The spray fan 10 includes a housing assembly 10a, a fan blade assembly 22, and a spray assembly 30. The housing assembly 10a is provided with a handheld housing 40, an air passage located at one end of the handheld housing 40, and an air outlet guard 24 arranged at one end of the air passage. It may be understood that one end of the handheld housing 40 is connected to the fan housing 21, and the fan housing 21 encloses an air passage and includes an air inlet guard 23 and an air outlet guard 24. The air outlet guard 24 is provided with a mist outlet hole 2410, and multiple air outlet holes 2420 annularly arranged at a periphery of the mist outlet hole 2410. The fan blade assembly 22 is mounted in the air passage. The spray assembly 30 includes a water tank 32, a water delivery pipeline 34, an atomizing portion 35, a fiber liquid guide strip 343, and an atomizer 31. The water tank 32 is arranged at the housing assembly 10a, the water delivery pipeline 34 is connected between the water tank 32 and the atomizing portion 34, the atomizing portion 35 is located at the mist outlet hole 2410, and the atomizer 31 is mounted at the atomizing portion 35 and exposed outside through the mist outlet hole 2410. The fiber liquid guide strip 343 is mounted in the water delivery pipeline 34, one end of the fiber liquid guide strip 343 extends into the water tank 32, and the other end of the fiber liquid guide strip 343 extends to an atomizing sheet.

Specifically, during use, a fan apparatus blows air in the fan, and meanwhile, water in the water tank 32 is transported into the atomizer 35 along the fiber liquid guide strip 343 in the water delivery pipeline 34, and then the water in the atomizing portion 35 is atomized by the atomizing sheet, and then mist spray is sprayed out through the mist outlet hole 2410. In this way, the mist outlet hole 2410 is in the middle of the multiple air outlet holes 2420, so the mist spray is in the middle of the airflow blown by the fan assembly 20, and the sprayed water mist will not be blown away. In addition, the fiber liquid guide strip 343 can stably transport the water to the atomizing sheet, so the spray interruption can be avoided, and stability of the spray mist is better.

According to the technical solution of the present invention, a housing assembly 10a, a fan assembly 20 and a spray assembly 30 are disposed. The housing assembly 10a is provided with a hand-held housing 40 and an air passage at one end of the hand-held housing 40, the fan assembly 20 is mounted in the air passage, and one end of the air passage is further provided with an air outlet guard 24. The air outlet guard 24 is provided with a mist outlet hole 2410, and multiple air outlet holes 2420 annularly arranged about the mist outlet hole 2410. The spray assembly 30 includes a water tank 32, at least one water delivery pipeline 34, an atomizing portion 35, a fiber liquid guide strip 343 and an atomizing sheet. The water tank 32 is arranged in the housing assembly 10a, and the water delivery pipeline 34 is connected between the water tank 32 and the atomizing portion 35. The atomizing portion 35 is located at the mist outlet hole 2410, the atomizing sheet is mounted at the atomizing portion 35 and exposed through the mist outlet hole 2410. The fiber liquid guide strip 343 is mounted in the water delivery pipeline 34, one end of the fiber liquid guide strip 343 extends into the water tank 32, and the other end of the fiber liquid guide strip 343 extends to the atomizer 31. In this way, even if the water delivery pipeline 34 is narrow, the fiber liquid guide strip 343 can continuously guide the water in the water tank 32 to the atomizer 31 in the atomizing portion 35, and the spray interruption can be avoided during the spraying of the atomizer 31. Moreover, the atomizing portion 35 is located at the mist outlet hole 2410, and the mist outlet hole 2410 is in the middle of the multiple air outlet holes 2420. In this way, the mist spray is in the middle of the fan assembly 20. Compared with a situation that the mist spraying position is located above or below the airflow, the mist spray will not be blown to deviate, and can be better integrated with the airflow, making the stability better.

As above, the housing assembly 10a includes a fan housing 21 and a handheld housing 40. The fan housing 21 is mounted at one end of the handheld housing 40, and provided with an air passage. The water tank 32 is arranged at one side, away from the handheld housing 40, of the fan housing 21. Specifically, the water tank 32 is arranged at a position of the fan housing 21 and located at one side away from the handheld housing 40, which can prevent the water tank 32 from being installed on the handheld housing 40, which would make the handheld housing too bulky and inconvenient for a user to hold. When air bubbles are generated in the atomizing portion 35, the air bubbles close to the fiber liquid guide strip will be absorbed by the fiber liquid guide strip 343 and float to an upper end of the fiber liquid guide strip 343 along the fiber liquid guide strip 343, so that unsmooth water flow caused by accumulation of air bubbles at the atomizing portion 35 and the water delivery pipeline 34 can be avoided.

In some embodiments, the fan housing 21 is arranged in a circular shape, the water tank 32 is arc-shaped, and is adaptively mounted at one side, away from the handheld housing 40, of the fan housing 21. Specifically, the air outlet guard 24 and the water tank 32 are both arc-shaped and in cooperation with each other. Compared with a conventional water tank 32, the water tank 32 can be prevented from protruding from an outer side of the air outlet guard 24.

In some embodiments, the number of the at least one water delivery pipeline 34 is two, which are arranged on both sides of the atomizing portion 35, respectively. One water delivery pipeline 34 is configured to communicate the atomizing portion 35 and one end of the water tank 32, and the other of the water delivery pipelines 34 is configured to communicate the atomizing portion 35 and the other end of the water tank 32. Specifically, the two water delivery pipes 34 are both provided with fiber liquid guide strips 343 to transport the water in the water tank 32 to the atomizer 31, so that the water guide is faster, and the water guide efficiency is higher.

It may be understood that one side (e.g., an outer frame 243 of the air outlet guard 24), away from the handheld housing 40, of the fan housing 21 may be provided with a mounting groove 211, and the water tank 32 is at least partially arranged in the mounting groove 211. Specifically, the water tank 32 is partially arranged in the mounting groove 211, making a part of the water tank 32 protruding from the fan housing 21 small. Moreover, the water tank 32 is limited by the air outlet guard 24, which can prevent the water tank 32 from shaking during use, and makes the structure of the water tank 32 firmer. In this way, the use of the handheld spray fan is more stable.

As above, the fan housing 21 includes an air outlet guard 24, and an air inlet guard 23. A rear side of the air outlet guard 24 is provided with an avoidance opening 2430, one side, away from the handheld housing 40, of the air outlet guard 24 is provided with a mounting groove 211, the water tank 32 is arranged in the mounting groove 211, and the water delivery pipeline 34 extends into the air outlet guard 24 through the avoidance opening 2430. The air inlet guard 23 is mounted on the rear side of the air outlet guard 24 to cover the avoidance opening 2430 and the rear side of the mounting groove 211. Specifically, the water tank 32 and the water delivery pipeline 34 can be placed between the air outlet guard 24 and the air inlet guard 23, and then the air outlet guard 24 and the air inlet guard 23 are mounted together, and the water delivery pipeline 34 extends into the avoidance opening 2430. The air inlet guard 23 and the mounting groove 211 form the installation groove 211, and the water tank 32 is arranged in the mounting groove 211. In this way, the air outlet guard 24 and the air inlet guard 23 are simple in structure and convenient to form, and convenient to assemble.

In some embodiments, the fan housing 21 is rotatably mounted on the handheld housing 40. Specifically, the fan assembly 20 includes a motor, and a blade assembly. The motor is mounted in the air outlet guard 24, and the blade assembly is mounted on a rotating shaft of the motor. When the air outlet guard 24 rotates relative to the handheld housing 40, the motor and the blade assembly rotate together with the air outlet guard 24. Therefore, the airflow blown out by the blade assembly can rotate accordingly, a blowing pitch angle of the fan assembly 20 can be adjusted by rotating the air outlet guard 24, and the user can use the fan more conveniently. Specifically, the handheld housing 40 includes a handheld main body 40b, and an arc-shaped bracket portion 40c connected to the handheld main body 40b, both ends of the arc-shaped bracket portion 40a are rotatably connected to two opposite sides of the fan housing 21, respectively, so that the fan assembly 20 can be arranged in a storage space of the arc-shaped bracket portion 40c and rotate relative to the handheld housing 40 to adjust a pitch blowing angle of the fan assembly 21.

Specifically, the handheld housing 40 may include two mounting portions 411 arranged at one end of the handheld housing 40, the two mounting portions 411 are arranged spaced apart from each other, rotation portions 212 are disposed on two opposite sides of the fan housing 21, and the two rotation portions 212 are coaxially arranged. The fan housing 21 is located between the two mounting portions 411, and each mounting portion 411 is rotatably connected to one mounting portion 411 correspondingly. Specifically, the fan housing 21 is mounted on the two mounting portions 411 through the rotating portions 212 on both sides. Compared with a way of mounting the fan housing 21 with only one rotating portion 212 and one mounting portion 411, the fan housing 21 is more stable and has a stronger structure when rotating.

Further, the water tank 32 may include a first trough body 311 and a first cover plate 322, the water delivery pipeline 34 includes a second trough body 312 and a second cover plate 331, and the atomizing portion 35 includes a third trough body 321 and a third cover plate 332. The first trough body 311, the second trough body 312 and the third trough body 321 are integrally formed, and the second trough body 312 is connected between the first trough body 311 and the third trough body 321. The first cover plate 322, the second cover plate 331 and the third cover plate 332 are integrally formed, the first cover plate 322 is correspondingly mounted on the first trough body 311, the second cover plate 331 is correspondingly mounted on the second trough body 312, and the third cover plate 332 is correspondingly mounted on the third trough body 321.

Specifically, after integrally forming the first trough body 311, the second trough body 312 and the third trough body 321, and integrally forming the first cover plate 322, second cover plate 331 and third cover plate 332, the water tank 32, the water delivery pipeline 34 and the atomizing portion 35 can be formed by covering the first trough body 311, the second trough body 312 and the third trough body 321 with the first cover plate 322, the second cover plate 331 and the third cover plate 333. Moreover, the mounting of the fiber liquid guide strip 343 is convenient, and the mounting of the fiber liquid guide strip 343 can be completed by placing a limit water guide strip between the second trough body 312 and the second cover plate 331 and then mounting the second trough body 312 and the second cover plate 331.

In some embodiments, the water tank 32, the water delivery pipeline 34 and the atomizing portion 35 are connected into a whole. Specifically, the molding of the water tank 32, the water delivery pipeline 34 and the atomizing portion 35 is relatively simple, and the assembling of the handheld spray fan is relatively convenient.

Further, the spray assembly 30 further includes a water guide sheet 355, the water guide sheet 355 is arranged in the atomizing portion 35 and attached to a back surface of the atomizer 31. Specifically, when the water tank 32 is located above the atomizing portion 35, a water pressure at the mist outlet hole 2410 is large. In this way, the water guide sheet 355 can prevent the water in the atomizing portion 35 from seeping out the mist outlet hole 2410. The water guide sheet 355 may be a cotton sheet.

It may be understood that the specific structures of the water tank 32, the water guide sheet 355, the fiber liquid guide strip 343, the atomizer 31, the decorative cover 36 and the like of the spray assembly 30 in this embodiment are basically the same as those in the first embodiment, and the description thereof will not be repeated here.

Further, the handheld housing 40 is internally provided with a main circuit board 41, the fan blade assembly 22 and the atomizer 32 are both electrically connected to the main circuit board 41. The handheld housing 40 is provided with a first key 421 and a second key 422 that are exposed outside, and the first key 421 and the second key 422 are both electrically connected to the main circuit board 41. The first key 421 is configured to control on/off and/or airflow volume of the fan blade assembly 22, and the second key 422 is configured to control the on/off of the atomizer 31. Specifically, the user can respectively control the fan assembly 20 and the spray assembly 30 through the two keys, the fan assembly 20 can be independently started to blow air, or the spray assembly 30 can be independently started to spray mist, which makes the use of the user more conveniently.

Further, the handheld housing 40 is internally provided with a charging battery 424, the charging battery 424 is electrically connected to the main circuit board 41, the handheld housing 40 is provided with a port assembly 423 exposed outside, and the port assembly 423 is electrically connected to the main circuit board 41 and connected to an external power supply for charging. Specifically, the handheld spray fan can be repeatedly charged for use, and there is no need for the user to additionally purchase a battery for replacement.

Further, the water injection port 370 of the water tank 32 is provided with a detachable sealing plug. In this way, the sealing effect of the water tank 32 is good, and compared with a method of disposing a threaded cap at the water injection port 370, such a water injection port 370 can be opened and closed more conveniently. In addition, in other embodiments, the water injection port 370 of the water tank 32 may be provided with a threaded cap. The sealing plug has the basically same structure as the sealing plug 371 in the first embodiment, and will not be described in detail here.

Further, a rear side of the water delivery pipeline 34 is provided with a second wire channel 340. In this way, an electric connection line between the atomizing sheet and the main circuit board 41 can pass through the second wire channel 340, which can prevent the electric connection line from being directly exposed to the outer side of the water delivery pipeline 34 and interfering with the motor or blade assembly.

Further, the rotation portion 212 is internally provided with a wire passing hole 210, the wire passing hole 210 communicates the second wire channel 340 and the inside of the handheld housing 40. In this way, an electric connection wire between the atomization sheet and the main circuit board 41 can enter the handheld housing 40 after passing through the second wire channel 340, then is connected to the main circuit board 41.

In this way, a remaining power of the battery 424 can be observed through bright and dark states of the multiple indicator lamps 425 or a color state of at least one indicator lamp 425.

Third Embodiment

Please referring to FIG. 18 to FIG. 23, the third embodiment of the present invention also provides a spray fan 10, and the spray fan 10 is also a handheld spray fan. It may be understood that parts of the spray fan 10 in the third embodiment that have essentially the same structure as those of the spray fans 10 in the first and second embodiment may not be described in detail in the third embodiment, but the descriptions in the first and second embodiments about basically the same structure as the third embodiment can be essentially appliable to the third embodiment.

In this embodiment, the spray fan 10 includes a fan assembly 20, a spray assembly 30, and a handheld housing 40. The fan assembly 20 includes a fan housing 21 and a fan blade assembly 22 arranged in the fan housing 21. The fan housing 21 includes an air inlet guard 23 located at an air inlet side A and an air outlet guard 24 located at an air outlet side B, the air outlet guard 24 includes a mist outlet portion 241 and multiple air outlet vanes 242 annularly connected around the mist outlet portion 241. The mist outlet portion 241 includes a mist outlet hole 2410, and multiple air outlet holes 2420 annularly arranged about the mist outlet hole 2410 are formed among the multiple air outlet vanes 242.

The atomizing assembly 30 includes an atomizer 31, and a water tank k32. The atomizer 31 is arranged in the fan housing 21 and corresponds to the mist outlet hole 2410. The water tank 32 includes a main tank body 33, at least one water delivery pipeline 34, and an atomizing portion 35. The at least one water delivery pipeline 34 communicates between the main tank body 33 and the atomizing portion 35, the atomizing portion 35 corresponds to the atomizer 31, and the atomizing portion 35 and the atomizer 31 are located between the fan blade assembly 22 and the air outlet guard 24, so that the fan blade assembly 22 can blow air from the air inlet side A to pass through a periphery of the atomizing portion 35 and a periphery of the atomizer 31 and spray the air out through the multiple air outlet holes 2420. Liquid in the main tank body 33 can be provided to the atomizer 31 through the at least one water delivery pipeline 34 and the atomizing portion 35, so that mist spray S formed by atomizing the liquid can be sprayed out from the mist outlet hole 2410 by the atomizer 31, and outlet airflow F from the multiple air outlet holes is annularly arranged about the mist spray S.

In the spray fan 10 in an embodiment of the present invention, the mist spray S formed by atomizing the liquid can be sprayed out from the mist outlet hole 2410 by the atomizer 31, the outlet airflow F of the multiple air outlet holes 2420 is annularly arranged about the mist spray, which makes the interference between the mist spray S of the spray fan 10 and the outlet airflow F relatively small, the air blowing and spray effects are both excellent, and the user experience is high.

At least one water delivery pipeline 34 is located at one side of the air outlet hole 2420. When viewed from an air outlet direction D1 of the air outlet hole 2420, a projection of the at least one water delivery pipeline 34 overlaps with that of at least one of the multiple air outlet holes 2420 or that of at least one of the air outlet vanes 242. In this embodiment, the spray fan 10 further includes at least one air shield structure 50. When viewed from the air outlet direction D1, a projection of the at least one air shield structure 50 overlaps with or is staggered from the projection of the at least one water delivery pipeline 34, and the at least one air shield structure 50 is configured to balance the outlet airflow of the multiple air outlet holes disrupted by at least one water delivery pipeline 34, making the outlet airflow of the multiple air outlet holes basically uniformly arranged around the mist spray S. A direction of the mist spray S is basically along a central axis of the mist outlet hole 2410. Because the airflow F of the multiple air outlet holes 2420 is basically uniformly arranged around the mist spray S, the mist spray S can be basically sprayed out along the air outlet direction D1, which not only has a good spraying effect, but also can avoid a phenomenon of water accumulation on the water outlet guard 24 or an element in front of the atomizer 31 (such as an outer surface of the decorative cover 36) caused by the deviation of the mist spray from the air outlet direction, making the user experience better.

It may be understood that when the number of the at least one water delivery pipeline 34 is multiple, and the multiple water delivery pipelines 34 are basically uniformly distributed in a circumferential direction of the air outlet guard 24, the number of the at least one air shield structure 50 may be the same as that of the at least one water delivery pipeline 34, and the projection of the air shield structure overlaps with that of the water delivery pipe, thereby achieving the effect of balancing the outlet airflow of the multiple air outlet holes 2420.

It may be understood that when the number of at least one water delivery pipeline 34 is one or more, and the water delivery pipelines are unevenly distributed in a circumferential direction of the air outlet guard 24, the number of at least one air shield structure 50 may be the same as or different from the number of at least one water delivery pipeline 34, but the projections of the air shield structure and the water delivery pipeline are staggered. In addition, the at least one air shield structure 50 and the at least one water delivery pipeline 34 are generally uniformly distributed in the circumferential direction of the air outlet guard 24, thereby achieving the effect of balancing the outlet airflow of the multiple air outlet holes 2420.

When viewed from the air outlet direction D1, the first air shield structure 51 and the second air shield structure 52 correspond to the first water delivery pipeline 341 and the second water delivery pipeline 342, respectively. When viewed from a circumferential direction of the air outlet guard 24, a circumferential distance W1 between the third air shield structure 53 and the first air shield structure 51 is equal to a circumferential distance W2 between the third air shield structure 53 and the second air shield structure 52, and a width H1 of the third air shield structure 53 is greater than or equal to a width H2 of the first air shield structure 51 and a width H2 of the second air shield structure 52.

At least one inner wall 332a includes two inner walls 332a, and the two inner walls 332a are located on both ends of the main tank body 33 and both ends of the decorative tank body 38, respectively. Each inner wall 332a is located between the cavity of the main tank body 33 and a cavity of the decorative tank body 38, and configured to separate the cavity of the main tank body 33 from the cavity of the decorative tank body 38. The fan housing 21 further includes an air guide housing 26, the air guide housing 26 is arranged between the air inlet guard 23 and the fan blade assembly 22, and an inner diameter of the air guide housing 26 gradually increases from the air inlet side A to the air outlet side B, and the air guide housing 26 is configured to guide the air from the air inlet guard 23 into the fan blade assembly 22.

In this embodiment, at least one air shield structure 50 includes a first air shield structure 51 and a second air shield structure 52. When viewed from an air outlet direction, the first air shield structure 51 and the second air shield structure 52 are located at a lower half side of the fan housing 21 in the direction of gravity D2. The first air shield structure 51 and the second air shield structure 52 are symmetrically arranged with the first water delivery pipeline 341 and the second water delivery pipeline 342, respectively.

Specifically, as shown in FIG. 30 and FIG. 31, the first air shield structure 51 and the second air shield structure 52 may include a first air shield 511 and a second air shield 512, the ends, close to the fan blade assembly 22, of the first air shield 511 and the second air shield 512 are connected. Specifically, the first air shield 511 and the second air shield 512 may be connected at a certain angle, but is not limited to the above, so that widths of the first air shield structure 51 and the second air shield structure 52 can gradually increase along air outlet direction. In addition, maximum widths of the first air shield structure 51 and the second air shield structure 52 may be essentially the same as those of the first water delivery pipeline 341 and the second water delivery pipeline 342, thereby achieving a better air balance effect.

It may be understood that the first air shield structure 51 and the second air shield structure 52 may also form air outlet holes 2420 with the air outlet vanes 242 on both sides.

Further, the fan housing 21 may also include a decorative hood 27, the decorative hood 27 is connected to one side, away from the fan blade assembly 22, of the atomizing portion 241 of the air outlet guard 24. The decorative hood 27 may be a decorative ring, and the decorative ring may be in snap fit with the mist outlet portion 241 through the fixing hole and the fixing post.

It may be understood that in this embodiment, the decorative cover 36 may be made of a metal material, multiple ribs 360 may be disposed on an outer surface of the decorative cover 36, and the multiple ribs 360 are annularly arranged on the outer surface of the decorative cover 36 to improve a water accumulation phenomenon of the mist spray S on the outer surface of the decorative cover 36, which is conducive to improving the product reliability.

Further, in this embodiment, an inner guard body 25 and an air outlet guard 24 are arranged on the air outlet side of the fan blade assembly 22 in turn. The air outlet guard 24 is provided with an atomizing portion 241, an outer frame 243 and air outlet vanes 242 connected between the atomizing portion 241 and the outer frame 243. The inner guard body 25 includes an inner frame 253 corresponding to the outer frame 243, multiple inner vanes 252 corresponding to the multiple air outlet vanes 242, and an inner plate portion 251 corresponding to the mist outlet portion 241. The multiple inner vanes 252 are connected between the inner plate portion 251 and the inner frame 253.

Multiple air outlet holes 2420 are formed among the multiple air outlet vanes 242, and multiple air holes 2520 are also formed between the multiple inner vanes 252.

The multiple air outlet vanes 242 are basically uniformly distributed in a circumferential direction of the air outlet guard 24, and each air outlet vane 242 is approximately arranged in a radius direction of the center of the annular structure of the air outlet guard 24. That is, a straight line where an extension direction R1 of each air outlet vane 242 is located passes through the center of the annular structure of the air outlet guard 24.

The multiple inner vanes 252 are basically uniformly distributed in a circumferential direction of the inner guard body 25, and each inner vane 252 deviates from a radius direction R2 of the center of the annular structure of the inner guard body 25 (the radius direction R2 is the same as the extension direction R1). That is, a straight line where an extension direction R3 of each inner vane 252 is located deviates from the center of the annular structure of the inner guard body 25, thereby being different from the extension direction R1 of each corresponding air outlet vane 242. In other words, the extension direction R3 of each inner vane 252 is different from the extension direction R1 of each corresponding air outlet vane 242, and an outer end of each inner vane 252 in the extension direction R3 (the end away from the center of the annular structure) deviates from the extension direction R1 toward a rotation direction R4 side of the fan blade assembly 22.

The extension direction R3 of each inner vane 252 is different from the extension direction R1 of each corresponding air outlet vane 242, so that the inner guard body 25 and the air outlet guard 24 form two air-gathering structures successively relative to the fan blade assembly 22. That is, the multiple inner vanes 252 and the multiple air outlet vanes 24 sequentially compress the outlet airflow of the fan blade assembly 22, so that the compressed outlet airflow can be blown out more concentratedly, which can effectively increase the airflow force to bring a cooler experience to the user.

In particular, the outer end of each inner vane plate 252 in the extension direction R3 (the end away from the center of the annular structure) deviates from the extension direction R1 toward a rotation direction R4 side of the fan blade assembly 22, which can further improve the compression effect of the outlet airflow, thereby increasing the airflow force.

It may be understood that parts of the spray fan 10 in the eighth embodiment that have essentially the same structure as those of the spray fans 10 in the first to seventh embodiment may not be described in detail in the eighth embodiment, but the descriptions in the first to seventh embodiments about essentially the same structure as the eighth embodiment can be essentially appliable to the eighth embodiment. The following mainly introduces the key parts of the spray fan 10 in the eighth embodiment or the differences from the spray fan 10 in the fourth embodiment.

Specifically, in the eighth embodiment, the fan assembly includes an air duct 10′ (which is equivalent to the inner guard body 25 in the fourth embodiment) and a blade assembly 20′. The air duct 10′ includes an outer duct body 11′, a mounting portion 12′ and multiple first blades 13′. The mounting portion 12′ is located inside the outer duct body 11′, and spaced apart from an inner wall surface of the outer duct body 11′. The multiple first blades 13′ are connected between the outer duct body 11′ and the mounting portion 12′, and distributed at intervals in a circumferential direction of the mounting portion 12′, and the outer duct body 11′ is provided with a mounting cavity 215′.

The blade assembly 20′ includes a hub 21′ and multiple second blades 22′. The hub 21′ is rotatably mounted at the mounting portion 12′, and arranged in the mounting cavity 215′. One side, away from the mounting portion 12′, of the hub 21′ is provided with a spherical surface 212′, and the multiple second blades 22′ are arranged on the spherical surface 212′ and distributed at intervals in a circumferential direction of the hub 21′, and an inclination direction of the second blades 22′ is opposite to that of the first blades 13′ (for example, when the first blade 13′ is right-handed, the second blade 22′ is left-handed; or, when the first blade 13′ is left-handed, the second blade 22′ is right-handed). A flow direction of the airflow is a direction that the first blade 13′ points to the second blade 22′.

According to the technical solution of the present invention, because the inclination direction of the second blade 22′ is opposite to that of the first blade 13′, after the blade assembly 20′ rotates to drive the airflow to enter the air duct 10′ and then to pass through the second blade 22′, the airflow can be compressed, so that the compressed airflow can be blown out more concentratedly, and the airflow force can be effectively increased. Moreover, a airward surface of the hub 21′ is configured as a spherical surface 212′, and the multiple second blades 22′ are arranged on the spherical surface 212′ to play a better guiding role on an operating spherical surface 212′ and effectively avoid the generation of turbulence, which not only can ensure that the airflow force is large, but also can avoid excessive noise.

In some embodiments, the hub 21′ includes a spherical shell 211′, a mounting inner cylinder 213′ and multiple reinforcing ribs 214. An outer side of the spherical shell 211′ is provided with a spherical surface 212′, and the multiple reinforcing ribs 214′ are arranged in the spherical shell 211′ and located at positions far away from the mounting portion 12′. The mounting inner cylinder 213′ is arranged in the spherical shell 211′ and located between the reinforcing ribs 214′ and the mounting portion 12′. Such an arrangement can increase the structural strength of the spherical shell 211′ through the reinforcing ribs 214′ and the mounting inner cylinder 213′. Moreover, the structure of the mounting inner cylinder 213′ is relatively regular, which is convenient for the mounting of the blade assembly 20′.

In some embodiments, the mounting portion 12′ is provided with a mounting shaft 121′, the mounting inner cylinder 213′ surrounds the mounting shaft 121′ at intervals to form a mounting cavity 215′ with the mounting shaft 121′. The fan blade assembly also includes a motor, the motor is mounted in the mounting cavity 215′, a stator of the motor is connected to the mounting shaft 121′, and a rotor of the motor is connected to the hub 21′. That is, the motor can be integrated into the fan blade assembly to improve the structure compactness of the fan blade assembly and facilitate the assembling of the handheld fan.

In some embodiments, one side, away from the hub 21′, of the mounting portion 12′ is provided with a mounting groove 122′ and a wire passing hole 123′ for communicating the mounting cavity 215′ and the mounting groove 122′, and the mounting groove 122′ is used for mounting a circuit board. In this way, the circuit board is mounted by using the mounting groove 122′, which is convenient for the wiring of the motor. A connector can be arranged on the circuit board to facilitate the wiring when assembling the handheld fan.

In some embodiments, the number of the first blades 13′ is greater than that of the second blades 22′. Such an arrangement can improve the air gathering effect and increase the airflow force.

In some embodiments, an area of the airward surface of the second blade 22′ is larger than that of the airward surface of the first blade 13′. In this way, when the second blade 22′ rotates, more airflow can be driven to flow, which can increase the airflow force.

In some embodiments, the fan blade assembly further comprises an air guide duct 30′ (equivalent to the air outlet guard 24 in the fourth embodiment), which is located at one side, away from the hub 21′, of the mounting portion 12′, and includes an outer duct portion 31′ (equivalent to the outer frame 243), a central part 33′ (equivalent to the atomizing portion 241) arranged in the outer duct portion 31′, and multiple connecting portions 32′ (equivalent to the air outlet vanes 242) connected between the outer duct portion 31′ and the central portion 33′. The outer duct portion 31′ is butted with the outer duct body 11′, and an outer diameter of the central portion 33′ is greater than that of the mounting portion 12′. That is, a spacing between the central portion 33′ and the outer duct portion 31′ is less than a spacing between the mounting portion 12′ and the outer duct body 11′. The airflow, when flowing between the central portion 33′ and the outer duct portion 31′, can be further compressed, which can increase the airflow force. Specifically, the outer duct portion 31′ is butted with the air duct 10′, and an outer diameter of the air duct 10′ is larger than that of the mounting portion 12′. The central portion 33′ is provided with a mist outlet hole 2410.

In some embodiments, the air guide duct 30′ is detachably connected to the outer duct portion 31′. As such, the air guide duct 30′ can be conveniently disassembled for maintenance.

In some embodiments, one side, away from the mounting portion 12′, of the central portion 33′ is provided with an accommodation groove 331′. As such, when used for the handheld fan, the circuit structure can be mounted in the accommodation groove 331′, which can improve a space utilization rate of the central portion 33′.

Referring to FIG. 86-89, in fifteenth embodiment, another spray fan 1000 is provided, which can achieve a slim design to reduce its space occupancy rate and facilitate user portability.

This spray fan 1000 comprises a housing 1100 and a fan assembly 1200; the housing 1100 has a first main surface 110a and a second main surface 110b arranged opposite each other, as well as at least one peripheral side surface 110c located between the first main surface 110a and the second main surface 110b, with each peripheral side surface 110c connected to both the first main surface 110a and the second main surface 110b. The area of each peripheral side surface 110c is less than that of the first main surface 110a, and also less than that of the second main surface 110b. The first main surface 110a is positioned on the air inlet side M of the spray fan 1000, while the second main surface 110b is located on the air outlet side N. The second main surface 110b is provided with air outlet holes 113a. Along the direction from the air inlet side M to the air outlet side N of the spray fan 1000, the diameter of at least part of the air outlet holes 113a gradually decreases. The fan assembly 1200 is arranged corresponding to the air outlet holes 113a and is mounted on the housing 1100.

The first main surface 110a and second main surface 110b are the outer surfaces of the housing 1100 and are arranged opposite to each other. The first main surface 110a and/or the second main surface 110b may be flat, curved, or a combination of flat and curved surfaces.

The at least one peripheral side surface 110c can be a plane, a curved surface, or a combination of a plane and a curved surface; for example, when both the first main surface 110a and the second main surface 110b are rectangular surfaces, the number of peripheral side surfaces 110c is four, and all four peripheral side surfaces 110c can be rectangular surfaces (based on the fact that the size and shape of the first and second main surfaces are exactly the same) or isosceles trapezoidal surfaces (based on the fact that the size and shape of the first and second main surfaces are different but similar). For another example, when both the first main surface 110a and the second main surface 110b are circular surfaces, the number of the peripheral side surface 110c is one, and this peripheral side surface 110c can be a cylindrical surface with equal diameters at both ends (based on the case where the size and shape of the first main surface 110a and the second main surface 110b are exactly the same) or a fan-shaped surface with different diameters at both ends (based on the case where the size of the first main surface 110a and the second main surface 110b is different but their shapes are similar).

The area of each peripheral side surface 110c is less than the area of the first main surface 110a, and the area of each peripheral side surface 110c is less than the area of the second main surface 110b. For example, when both the first and second main surfaces 110a and 110b are rectangular surfaces, and all four peripheral side surfaces 110c are rectangular surfaces, by designing the area of each peripheral side surface 110c to be less than that of the first main surface 110a and the area of each peripheral side surface 110c to be less than that of the second main surface 110b, the housing 1100 as a whole is made into a flat rectangular body. For another example, when both the first main surface 110a and the second main surface 110b are circular surfaces, and the peripheral side surface 110c is a cylindrical surface, by designing the area of the peripheral side surface 110c to be less than that of the first main surface 110a, and designing the area of the peripheral side surface 110c to be less than that of the second main surface 110b, the housing 1100 as a whole is made into a flat cylindrical shape. The flat housing 1100 can realize the lightweight design of the spray fan 1000, reduce the space occupation of the spray fan 1000, and facilitate the user to carry.

The first main surface 110a is located at the air inlet side M of the spray fan 1000 (that is, the side where the air supply flow of the spray fan 1000 flows into the fan assembly 1200), and the second main surface 110b is located at the air outlet side N of the spray fan 1000 (that is, the side where the air supply flow of the spray fan 1000 flows out of the fan assembly 1200).

The second main surface 110b is provided with an air outlet 113a, along the direction of from the air inlet side M of the spray fan 1000 to the air outlet side N of the spray fan 1000, and the aperture of at least part of the air outlet 113a gradually decreases. For example, the aperture of the air outlet hole 113a can gradually decrease along the direction that the air inlet side M of the spray fan 1000 to the air outlet side N of the spray fan 1000 (as shown in FIG. 89, the distance between the hole wall surface of the air outlet hole 113a and the hole axis of the air outlet hole 113a gradually decreases along the direction that the air inlet side M of the spray fan 1000 points to the air outlet side N of the spray fan 1000). For another example, the hole diameter of the air outlet 113a may increase first and then decrease along the direction that the air inlet side M of the spray fan 1000 to the air outlet side N of the spray fan 1000. For another example, the hole diameter of the air outlet 113a can be reduced first and then increased along the direction that the air inlet side M of the spray fan 1000 to the air outlet side N of the spray fan 1000. It can be understood that in the direction where the air inlet side M of the spray fan 1000 to the air outlet side N of the spray fan 1000, the hole wall surface of the air outlet 113a is designed to be at least partially closed. On the one hand, it can guide the air flow to gather in the middle, so that the air flow can be more concentrated to the target area, and on the other hand, it can improve the air speed. A higher air speed means that the air flow has greater kinetic energy, which can be blown farther away, so that the heat exchange efficiency or cooling efficiency is higher. In addition, from the air inlet side M of the spray fan 1000 to the air outlet side N of the spray fan 1000, the hole wall surface of the air outlet 113a is designed to be at least partially tapered, providing a smooth transition for the air flow, enabling the air flow streamline to smoothly fit the hole wall flow, greatly reducing the air separation and the resulting large-scale turbulence, thus reducing the noise.

The fan assembly 1200 is used to drive air flow to form an airflow. The fan assembly 1200 corresponds to the air outlet hole 113a and is installed in the housing 1100. The specific installation method between the fan component 1200 (specifically the mounting bracket 1210 described below) and the housing 1100 is not limited here, and designers can make reasonable designs according to actual needs; For example, the fan component 1200 (specifically the mounting bracket 1210 described below) can be detachably connected to the housing 1100 through at least one of screw connection, card connection, or plug connection, but not limited to; For example, the fan component 1200 (specifically the mounting bracket 1210 described below) can also be non removable connected to the housing 1100 through adhesive or riveting, but not limited to.

Based on the spray fan 1000 in the embodiment of the present application, the housing 1100 is flat as a whole by the area of the peripheral side surface 110c is less than the area of the first main surface 110a, and the area of the peripheral side surface 110c is less than the area of the second main surface 110b. Such a flat housing 1100 can realize the lightweight design of the spray fan 1000, reduce the space occupation rate of the spray fan 1000, and facilitate the user to carry. In the direction from the air inlet side M of the spray fan 1000 to the air outlet side N of the spray fan 1000, the hole wall surface of the air outlet 113a is designed to be at least partially tapered, i.e, is partially decreased from the air inlet side M of the spray fan 1000 to the air outlet side N of the spray fan 1000. This design, on the one hand, it can guide the air flow to gather in the middle, so that the air flow can be more concentrated to the target area, and on the other hand, it can improve the air speed. A higher air speed means that the air flow has greater kinetic energy, which can be blown farther away, so that the heat exchange efficiency or cooling efficiency is higher. In addition, from the air inlet side M of the spray fan 1000 to the air outlet side N of the spray fan 1000, the hole wall surface of the air outlet 113a is designed to be at least partially tapered, providing a smooth transition for the air flow, enabling the air flow streamline to smoothly fit the hole wall flow, greatly reducing the air separation and the resulting large-scale turbulence, thus reducing the noise.

Referring to FIG. 86, 87, 90-92, the housing 1100 includes a water tank 1110, which includes a first front shell 111a, a first back shell 111b, and a first side shell 111c. The first front shell 111a and the first back shell 111b are arranged opposite to each other, and the first side shell 111c is located between the first front shell 111a and the first back shell 111b and is sealingly connected to them. The outer surface of the first back shell 111b is used to form a portion of the first main surface 110a (i.e., the first main surface 110a includes the outer surface of the first back shell 111b), and a portion of the outer surface of the first side shell 111c is used to form a portion of the peripheral side surface 110c (i.e., the peripheral side surface 110c includes a portion of the outer surface of the first side shell 111c). Among them, the first side shell 111c and the first back shell 111b can be a separate structure or an integrated structure. When the first side shell 111c and the first back shell 111b are a separate structure, the first side shell 111c can be sealed and connected to the first back shell 111b through ultrasonic welding to form a combination. When the first side shell 111c and the first back shell 111b are an integrated structure, the first side shell 111c can be, but is not limited to, molded as a whole with the first back shell 111b through injection molding or 3D printing. The combination formed by the first front shell 111a, the first side shell 111c, and the first back shell 111b is designed in a separate manner, and the first front shell 111a can be sealed and connected to the combination formed by the first side shell 111c and the first back shell 111b as a whole through ultrasonic welding.

The housing 1100 also comprises a bottom shell 1120, which is arranged on one side of the water tank 1110, and the bottom shell 1120 comprises a second back shell 112a and a second side shell 112b. The second side shell 112b is connected with the second back shell 112a and encircled with the first side shell 111c to form an accommodation cavity 112c with cavity opening set towards the air outlet side N of the spray fan 1000. The outer surface of the second back shell 112a is used to form the remaining part of the first main surface 110a (that is, the first main surface 110a also includes the outer surface of the second back shell 112a), and the outer surface of the second side shell 112b is used to form the remaining part of the peripheral side surface 110c (that is, the above-mentioned peripheral side surface 110c also includes the outer surface of the second side shell 112b). Among them, the second side shell 112b and the second back shell 112a can be a separate structure or an integrated structure. When the second side shell 112b and the second back shell 112a are separate structures, the second side shell 112b can be sealed and connected to the second back shell 112a by ultrasonic welding to form another assembly. When the second side shell 112b and the second back shell 112a are integrated structures, the second side shell 112b can be integrated with the second back shell 112a through injection molding or 3D printing, but not limited to.

The housing 1100 also includes an outer shell 1130, which has the aforementioned second main surface 110b and the aforementioned air outlet hole 113a, i.e., the outer shell 1130 is located at the outer surface of the spray fan. The outer shell 1130 is connected to at least one of the water tank 1110 and the bottom shell 1120 to cover the first front shell 111a and the cavity opening of the accommodating chamber 112c. Among them, the specific connection method between the opposite shell 1130 and the water tank 1110 (and/or the bottom shell 1120) is not limited here, and designers can make reasonable designs according to actual needs; for example, the outer shell 1130 can be, but is not limited to, detachably connected to the water tank 1110 (and/or the bottom shell 1120) through at least one of screwing, clamping, or plugging methods; for another example, the outer shell 1130 can also be non removable connected to the water tank 1110 (and/or the bottom shell 1120) through adhesive bonding or riveting, but not limited to.

The water tank 1110 is equipped with a perforation 111f, and the outer shell 1130 is equipped with an installation hole 113e corresponding to the perforation 111f. When the installation hole 113e is a threaded hole, a screw is threaded through the perforation 111f and connected to the threaded hole to achieve relative fixation between the water tank 1110 and the outer shell 1130; when the installation hole 113e is a snap fit hole, the snap pin is pierced through a hole 111f and connected to the snap fit hole to achieve relative fixation between the water tank 1110 and the outer shell 1130.

The bottom shell 1120 is equipped with at least one of a buckle 113f and a buckle hole 112d, and the side of the outer shell 1130 facing the bottom shell 1120 is equipped with at least the other of the buckle 113f and the buckle hole 112d. The buckle 113f is engaged with the buckle hole 112d to achieve relative fixation of the position between the bottom shell 1120 and the outer shell 1130.

By designing the housing 1100 three mutually independent parts, namely, the water tank 1110, the bottom shell 1120 and the outer shell 1130, the water tank 1110 is used for water storage, and the water tank 1110 is also used as the shell of the spray fan 1000 as a part of the housing 1100, which can save materials and reduce production costs. Compared with the design of the water tank 1110 inside the spray fan 1000, it is also conducive to achieving the lightweight design of the spray fan 1000.

As shown in FIGS. 86, 87, 90-92, the outer surface of the first back shell 111b is provided with an air inlet hole 111b1, the outer surface of the first front shell 111a is provided with a first through hole 111a1 corresponding to the air inlet hole 111b1, and the air outlet hole 113a is provided corresponding to the first through hole 111a1. The water tank 1110 also includes an inner shell 111d, which is arranged around the air inlet hole 111b1 and the first through hole 111a1. The two ends of the inner shell 111d are respectively sealed and connected to the first front shell 111a and the first back shell 111b, so that the first front shell 111a, the first back shell 111b, the first side shell 111c, and the inner shell 111d are enclosed together to form a water storage chamber 111e. Among them, the inner shell 111d and the first back shell 111b can be a separate structure or an integrated structure. When the inner shell 111d and the first back shell 111b are a separate structure, the inner shell 111d can be sealed and connected to the first back shell 111b by ultrasonic welding to form a combination. When the inner shell 111d and the first back shell 111b are an integrated structure, the inner shell 111d can be integrated with the first back shell 111b through injection molding or 3D printing, but not limited to. The combination formed by first front shell 111a, the first side shell 111c, the first back shell 111b, and the inner shell 111d is designed in a separate manner, and the first front shell 111a can be sealed and connected to the combination formed by the first side shell 111c, the first back shell 111b, and the inner shell 111d as a whole through ultrasonic welding.

The fan assembly 1200 is located within a hollow area 111d1 enclosed by the inner shell 111d. In this way, while ensuring that sufficient water can be stored in the water storage chamber 111e of the water tank 1110, the fan assembly 1200 can make the fan assembly 1200 and the water tank 1110 more compact in spatial layout by reasonably utilizing the hollow area 111d1 enclosed by the inner shell 111d, which is also conducive to the miniaturization design of the spray fan 1000 and easy for users to carry.

The fan assembly 1200 includes a mounting bracket 1210, a motor 1220, and a fan blade body 1230. The mounting bracket 1210 is connected to the inner shell 111d, the motor 1220 is connected to the mounting bracket 1210, and the fan blade body 1230 is connected to the rotating shaft of the motor 1220.

Among them, the specific connection method between the mounting bracket 1210 and the inner shell 111d is not limited here, and designers can make reasonable designs according to actual needs; for example, the mounting bracket 1210 can be, but is not limited to, detachably connected to the inner shell 111d through at least one of screw connection, clamping or buckle connection, or plug-in connection; for example, the mounting bracket 1210 can also, but is not limited to, be non removable connected to the inner shell 111d through adhesive bonding or riveting. Specifically, the mounting bracket 1210 includes a base body 121a, a surrounding wall 121c, and multiple air outlet grilles 121b. The base body 121a has a mounting cavity 121a1, and the surrounding wall 121c is arranged around the circumference of the base body 121a and spaced apart from the base body 121a. Multiple air outlet grilles 121b are located in the gap between the base body 121a and the surrounding wall 121c and arranged around the circumference of the base body 121a. One end of the multiple air outlet grilles 121b is connected to the base body 121a, and the other end of the multiple air outlet grilles 121b is connected to the surrounding wall 121c. The outer side of the surrounding wall 121c is provided with at least one of a clamping flange 111g and a clamping groove 121d, and the surface of the inner shell 111d is provided with at least the other one of the clamping flange 111g and the clamping groove 121d, wherein the clamping flange 111g is engaged with the clamping groove 121d to achieve relative fixation of the position between the mounting bracket 1210 and the inner shell 111d.

The specific connection method between motor 1220 and mounting bracket 1210 is not limited here, and designers can make reasonable designs according to actual needs; for example, the motor 1220 can be detachably connected to the mounting bracket 1210 through at least one of screw connection, clamping or buckle connection, or plug-in connection. For another example, the motor 1220 can also be non removable connected to the mounting bracket 1210 through adhesive bonding or riveting, but not limited to. Specifically, the motor 1220 is located in the mounting cavity 121a1 of the base body 121a and is connected to the base body 121a by locking screws.

The specific connection method between the fan blade body 1230 of the fan blade and the rotating shaft of the motor 1220 is not limited here, and designers can make reasonable designs according to actual needs; for example, the fan blade body 1230 can be, but is not limited to, detachably connected to the shaft of the motor 1220 through at least one of screw connection, card connection, or plug-in connection.

By designing the mounting bracket 1210, motor 1220, and fan blade body 1230, the motor 1220 is connected to the inner shell 111d of the water tank 1110 through the mounting bracket 1210. The motor 1220 works to drive the fan blade body 1230 to rotate, and the fan blade body 1230 rotates to promote air flow and form an airflow, in order to achieve the purpose of cooling.

The water tank 1110 further includes an air inlet cover 111h, which is located within the hollow region 111d1 formed by the inner shell 111d and is arranged adjacent to the air inlet hole 111b1. The air inlet cover 111h is connected to the inner shell 111d. Among these, the air inlet cover 111h and the inner shell 111d can be either a separate structure or an integrated structure. When the air inlet cover 111h and the inner shell 111d are a separate structure, the air inlet cover 111h can be sealed and connected to the inner shell 111d as a combined unit through ultrasonic welding. When the air inlet cover 111h and the inner shell 111d are an integrated structure, the air inlet cover 111h can be formed integrally with the inner shell 111d through methods such as injection molding or 3D printing, but is not limited to these methods.

As shown in FIGS. 86, 87, 90-93, the outer surface of first front shell 111a is also equipped with an water outlet 111a2 connected to the water storage cavity 111e of tank 1110, while the outer surface of outer shell 1130 features a second through hole 113b corresponding to water outlet 111a2. The spray fan 1000 further includes a spray assembly 1300, which consists of an atomizer 1310 and a sealing element 1320. The atomizer 1310 is positioned corresponding to the water outlet 111a2 and is configured to atomize water from the water storage cavity 111e of tank 1110, forming mist spray. The sealing element 1320 ensures tightness at the gap between the atomizer 1310 and first front shell 111a at the water outlet 111a2. The atomizer 1310 may include, but is not limited to, ultrasonic humidifiers, atomizing plates 131a, or piezoelectric nozzles. The sealing element 1320 may comprise elastic sealing rings 132a or sealing adhesive layers. By designing the atomizer 1310, it atomizes water from the water storage cavity 111e of tank 1110 to form mist spray (composed of countless tiny water droplets). The heat absorption process accompanying spray evaporation effectively removes heat from the airflow blown at the air outlet hole 113a, resulting in genuinely cooled air. This enhances the cooling and heat-relieving effect. Through the design of the sealing element 1320, it seals the gap between the atomizer 1310 and first front shell 111a at the water outlet 111a2, preventing water leakage from the water outlet 111a2 of tank 1110 and ensuring effective sealing. Motor 1220 drives the rotation of fan blade body 1230, which moves air to create airflow (i.e., wind). During this process, the atomizer 1310 atomizes water from the water storage cavity 111e of tank 1110, forming spray that exits through the second through hole 113b of outer shell 1130. The evaporation of spray absorbs heat, effectively cooling the airflow blown air outlet hole 113a to achieve the purpose of temperature reduction and heat relief.

Specifically, the outer surface of first front shell 111a is also equipped with a mounting groove 111a3, which is arranged around the water outlet 111a2. The atomizer 1310 includes an atomizing sheet 131a, and the sealing element 1320 includes an elastic sealing ring 132a. The elastic sealing ring 132a is fitted over the atomizing sheet 131a and achieves an interference fit with the sidewall of the mounting groove 111a3, thereby securing the atomizing sheet 131a to the first front shell 111a. The spray fan 1000 also includes a first sealing plug 1400, which is movably connected to the outer shell 1130 to open or close the second through hole 113b of the outer shell 1130. The first sealing plug 1400 can be connected to the outer shell 1130 via a rotating joint. In this configuration, when the user needs to utilize the spray function of the spray fan 1000, the first sealing plug 1400 is rotated to open the second through hole 113b, allowing the spray formed by the atomizing sheet 131a to be discharged through the second through hole 113b. Conversely, when the spray function is not required, the first sealing plug 1400 is rotated to close the second through hole 113b. Alternatively, the first sealing plug 1400 can be connected to the outer shell 1130 via a sliding joint; in this case, when the spray function is needed, the first sealing plug 1400 is slid to open the second through hole 113b, enabling the spray to be discharged through the second through hole 113b; when the spray function is not required, the first sealing plug 1400 is slid to close the second through hole 113b.

In particular, referring to FIGS. 91 and 93, specifically, when the first sealing plug 1400 is rotatably connected to the outer shell 1130, the first sealing plug 1400 includes a main body 1410, a sealing portion 1420, and a rotating shaft 1430. The main body 1410, the sealing portion 1420, and the rotating shaft 1430 can be integrally formed by injection molding. The rotating shaft 1430 passes through a through-hole on the outer shell 1130 and is designed with an anti detachment flange. Users can apply force to the main body 1410 to allow the sealing part 1420 open or close the second through hole 113b. By designing the rotating shaft 1430 to connect it to the outer shell 1130, the first sealing plug 1400 will not detach from the outer shell 1130 (see FIG. 93), effectively avoiding the loss of the first sealing plug 1400.

By designing the atomizer 1310 as an atomizing sheet 131, and designing the sealing element 1320 as an elastic sealing ring 132a, which is looped around the periphery of the atomizing sheet 131, it is possible to avoid direct contact between the rigid atomizing sheet 131 and the rigid first front shell 111a, which may cause damage to the atomizing sheet 131. By designing an mounting groove 111a3 on the outer surface of first front shell 111a, the elastic sealing ring 132a can fit snugly with the groove wall surface of the mounting groove 111a3; on one hand, it can effectively seal the gap between the atomizing sheet 131a and first front shell 111a at the water outlet 111a2, avoiding water leakage at the water outlet 111a2 of the water tank 1110 and providing a good sealing effect; on the other hand, it can achieve relative fixation of the position between the atomizing sheet 131a and first front shell 111a, reducing the assembly difficulty between the atomizing sheet 131a and first front shell 111a. By designing the first sealing plug 1400, it can close the second through hole 113b of the outer shell 1130 to achieve dual sealing in conjunction with the design of the sealing element 1320 mentioned above. Of course, the sealing element 1320 can also include a sealing adhesive layer; in this case, the atomizing sheet 131a achieves relative fixation with the first front shell 111a through the sealing adhesive layer, as well as sealing with the first front shell 111a at the water outlet 111a2.

The outer surface of the first side shell 111c is provided with a water inlet 111c1 which is in communication with the water storage cavity 111e of the water tank 1110. The spray fan 1000 also includes a second sealing plug 1910, which is movably connected with the first side shell 111c to open or close the water inlet 111c1. Among them, the second sealing plug 1910 can be connected with the first side shell 111c by rotating connection; at this time, when the user needs to inject water into the water storage cavity 111e of the water tank 1110, rotate the second sealing plug 1910 to open the water inlet 111c1, so that the water flows from the water inlet 111c1 to the water storage cavity 111e of the water inlet tank 1110. After water storage cavity 111e is filled with water, rotate the second sealing plug 1910 until water inlet 111c1 is closed. The second sealing plug 1910 can also be connected to the first side shell 111c by sliding connection; at this time, when the user needs to fill the water storage chamber 111e of the water tank 1110 with water, slide the second sealing plug 1910 to open the water inlet 111c1, so that water flows from the water inlet 111c1 into the water storage chamber 111e of the water tank 1110; after the water storage chamber 111e of the water tank 1110 is filled with water, slide the second sealing plug 1910 to close the water inlet 111c1.

The second switch 1540 can be another button, and at this time, the second electrical signal is generated by pressing the other button. Each time the other button is pressed, the other button generates a second electrical signal, in this way, the user presses the other button multiple times to make the controller of the main control board 1510 control the atomization gear of the atomizer 1310 according to the second electrical signal. The second switch 1540 can also be another knob. At this time, the second electrical signal is generated by rotating the other knob; every time the other knob is rotated, the other knob generates a second electrical signal, in this way, the user rotates the other knob multiple times to make the controller of the main control board 1510 control the atomization gear of the atomizer 1310 according to the second electrical signal. It should be noted that the particle diameter of the spray formed by atomizer 1310 in the first stage atomization gear is larger than the particle diameter of the spray formed by atomizer 1310 in the second stage atomization gear is larger than the particle diameter of the spray formed by atomizer 1310 in the third stage atomization gear.
