An electronic atomizing device 300 is provided in this disclosure. FIG. 1 is a structural schematic view of an electronic atomizing device according to an embodiment of the present disclosure. FIG. 2 is a lateral structural view of an atomizer of the electronic atomizing device in FIG. 1. FIG. 3 is a cross-sectional structural schematic view of the atomizer in direction III-III in FIG. 2.

The electronic atomizing device 300 may be used for atomizing the e-cigarette liquid. The electronic atomizing device 300 may include an atomizer 100 and a body assembly 200 connected to the atomizer 100. The atomizer 100 may be used for storing liquid and atomizing the liquid to form smoke that can be inhaled by a person. The liquid may be liquid matrix such as e-liquid, liquid medicine, etc. The body assembly 200 can be used to supply power to the atomizer 100 for atomizing the e-liquid and forming smoke.

In this embodiment, the case of using e-liquid as the liquids will be described in detail.

The atomizer 100 generally includes a liquid storage assembly 101 and an atomizing core assembly 102. The atomizing core assembly 102 can be arranged in the liquid storage assembly 101. The liquid storage assembly 101 can be used to store the e-liquid, the atomizing core assembly 102 can be used to atomize the e-liquid to form smoke.

Specifically, the liquid storage assembly 101 includes a housing 10, an inner wall 30 and a cigarette holder 40. The housing 10 defines a liquid storage cavity 120 and a first assembling hole 140 (as shown in FIG. 5 and FIG. 6). The first assembling hole 140 can be used to receive an end of the atomizing core assembly 102. An inner wall 30 is arranged in the liquid storage cavity 120. The cigarette holder 40 covers the housing 10. The atomizing core assembly 102 is arranged in the liquid storage cavity 120, and has a liquid inlet 52. A capillary gap 31 capable of generating capillary action is defined between the inner wall 30 and an outer wall of the atomizing core assembly 102. When liquid level of the housing 10 below a position of the liquid inlet 52, the e-liquid stored in the storage assembly 101 may be guided to the liquid inlet 52 along the capillary gap 31. The e-liquid could be guided to the liquid inlet 52 and be atomized by the atomizing core assembly 102, therefore improving a utilization rate of the e-liquid and reducing waste of the e-liquid.

In some embodiments, the atomizing core assembly 102 and the liquid storage assembly 101 can be detachably connected, such that the atomizing core assembly 102 could be replace. Referring to FIG. 3, the atomizing core assembly 102 could be pulled out from the bottom side of the atomizer 100, so as to install a new atomizing core assembly 102 into the atomizer 100. When the atomizing core assembly 102 is needed to be replaced, a user could turn the atomizer 100 upside down, and pull out the atomizing core assembly 102, such that remaining e-liquid in the liquid storage cavity 120 could be placed on a side far away from the base 20 under gravity, and the inner wall could block the e-liquid, and the e-liquid cannot move into the atomizing core assembly 102. Therefore, the e-liquid remaining in the liquid storage cavity 120 cannot leak out due to blocking of the inner wall 30, thereby avoiding the e-liquid leakage during the replacement of the atomizing core assembly 102, improving user experience.

In this embodiment, referring to FIG. 3 and FIG. 5, the housing 10 includes a cylinder 12, a cover 14 and a base 20, the cover 14 is arranged on an end of the cylinder 12, and the base 20 is arranged on the other end of the cylinder 12. The cover 14, the cylinder 12 and the base 20 cooperatively define the liquid storage cavity 120. The liquid storage cavity 120 is used for storing e-liquid. The cover 14 defines the first assembling hole 140 communicating with the liquid storage cavity 120. The first assembling hole 140 is used to receive the end of the atomizing core assembly 102.

The cover 14 defines an air hole 142, and the air hole 142 communicates with the liquid storage cavity 120. A waterproof ventilated membrane 144 covers the air hole 142 for reducing a possibility of the e-liquid in the liquid storage cavity 120 leaking from the air hole 142, which could facilitate gas exchange between the liquid storage cavity 120 and atmosphere. As a result, air pressure in the liquid storage cavity 120 can be kept consistent with the atmospheric pressure, thereby improving an ability of the atomizer 100 to withstand higher temperatures. Therefore, intracavity temperature of the liquid storage cavity 120 will not excessively fluctuate and an unbalance between the intracavity pressure and atmospheric pressure will not happen. In this way, it is possible to avoid liquid leakage caused by excessively high air pressure in the liquid storage cavity 120, which is beneficial to reduce liquid leakage of the atomizer 100.

The cover 14 further defines a liquid injection hole 145 and a mounting hole 146, the liquid injection hole 145 and the mounting hole 146 are communicated with the liquid storage cavity 120. Referring to FIG. 3 and FIG. 7, the liquid storage assembly 101 further includes a sealing plug 15. The sealing plug 15 includes a connecting cover plate 150. A first sealing column 152 and a second sealing column 154 are disposed on one side of the connecting cover plate 150. The first sealing column 152 is configured to seal off the liquid injection hole 145, and the second sealing column 154 is configured to seal off the mounting hole 146.

In some embodiments, the liquid injection hole 145 has a larger hole diameter than that of the mounting hole 146.

In this embodiment, the sealing plug 15 may be made of silicone material, plastic material, etc., and the sealing plug 15 can be configured to block and seal off the first injection hole 145 and the second injection hole 146.

During a process of injecting liquid, liquid can be injected into the liquid storage cavity 120 through the liquid injection hole 145. The mounting hole 146 can communicate with the atmosphere and the liquid storage cavity 120. In this way, during the liquid injection process, the sealing plug 15 can rotate around sealed mounting hole 146 to expose unsealed liquid injection hole 145. The liquid can be injected into the liquid storage cavity 120 through the unsealed liquid injection hole, such that the sealing plug 15 does not need to be completely separated from the cover 14 during the process of injecting liquid, which can reduce a possibility of the sealing plug 15 being lost.

Referring to FIGS. 3 and 8, a base 20 is arranged at the other end of the cylinder 12 away from the cover 14. The base 20 is connected to the cylinder 12 in a sealing manner, the base 20 defines a second assembling hole 21 corresponding to the first assembling hole 140. The second assembling hole 21 is used to receive another end of the atomizing core assembly 102.

In this embodiment, the cylinder 12 and the cover 14 are formed of a single piece, and the base 20 is detachably connected to the cylinder 12. In other embodiments of the present disclosure, the cylinder 12 and the cover 14 also can be detachably connected and/or the base 20 and the housing 10 can be formed of a single piece.

In other embodiments, the housing 10 may be in a shape of an ellipse, a sphere, a cylinder, or a diamond, or the housing 10 may have a split combination structure. The housing 10 may include a spherical housing and a bottom cover. The bottom cover and the spherical housing are connected to form the liquid storage cavity 120. In other embodiments, the housing 10 may include a rectangular housing and a top cover. The rectangular housing and the top cover are connected to form the liquid storage cavity 120.

In some embodiments, referring to FIG. 9 and FIG. 10, the atomizing core assembly 102 is installed from the first assembling hole 140 to the second assembling hole 21. A retaining ring 22 is arranged at the base 20 and around the second assembling hole 21. The inner wall 30 is located outside the retaining ring 22. The retaining ring 22 is further assembled and hermetically connected to the atomizing core assembly 102. The retaining ring 22 is configured to block the residual e-liquid in the liquid storage cavity 120, so as to reduce a possibility of the residual e-liquid entering the second assembling hole 21 and leaking out when the atomizing core assembly 102 is removed from one side of the cover 14.

The base 20 further defines an air inlet 23, and the base 20 include an electrode 24 electrically connected with the atomizing core assembly 102. The air inlet 23 is communicated with an atomizing cavity in the atomizing core assembly 102. Air entering the atomizing cavity from the air inlet 23 can carry smoke in the atomizing cavity to a human oral cavity.

In some embodiment, the atomizing core assembly 102 could be pulled out from the top side of the atomizer 100 (as shown in FIG. 10). When the atomizing core assembly 102 replacement operation is needed, the user could remove the cigarette holder 40 firstly, and then pull out the atomizing core assembly 102. In this embodiment, in order to prevent the e-liquid in the liquid storage cavity 120 from leaking out, a blocking member 27 could be arranged on the base 20 to prevent the e-liquid in the liquid storage cavity 120 from leaking out from air inlet 23 during the replacement process of the atomizing core assembly 102.

In other embodiments, referring to FIGS. 3, 5 and 8, the atomizing core assembly 102 is installed from the second assembling hole 21 to the first assembling hole 140. A retaining ring 22 is arranged on the cover 14 and around the first assembling hole 140. The inner wall 30 is located outside the retaining ring 22. The retaining ring 22 is used to block the residual e-liquid in the liquid storage cavity 120, so as to reduce a possibility of the residual e-liquid entering the first assembling hole 140 and leaking out when the atomizing core assembly 102 is removed from one side of the base 20.

The atomizing core assembly 102 defines an air inlet 23, the atomizing core assembly 102 includes an electrode 24, the air inlet 23 is communicated with an atomizing cavity of the atomizing core assembly 102, and the electrode 24 is electrically connected to an atomizing member 70 of the atomizing core assembly 102.

The inner wall 30 is disposed corresponding to the liquid inlet 52, such that the capillary gap 31 can communicate with the liquid inlet 52. When the liquid level of the liquid storage cavity 120 is below the position of the liquid inlet 52, the liquid in the liquid storage cavity 120 can enter the liquid inlet 52 along the capillary gap 31 by the capillary action. Therefore, the residual e-liquid can flow into the liquid inlet 52 to be atomized by atomizing core assembly 102, which could improve the utilization rate of the e-liquid and reduce the waste of the e-liquid.

A gap 32 is defined between the base 20 and an end of the inner wall 30 facing the base 20. The gap 32 is in communication with the capillary gap 31. The thickness of the gap 32 is greater than or equal to 0.5 mm. The gap 32 is configured to allow the e-liquid in the liquid storage cavity 120 to pass through the capillary gap 31. The e-liquid can be guided to the liquid inlet 52 along the capillary gap 31 by the capillary action. Therefore, the e-liquid at the bottom of the liquid storage cavity 120 can flow into the liquid inlet 52 along the capillary gap 31, which could improve the utilization rate of the e-liquid and reducing the waste of the residue e-liquid. A width of the gap 32 can be greater than or equal to 0.5 mm, which could facilitate the e-liquid entering the capillary gap 31 from the gap 32.

The atomizing core assembly 102 defines the liquid inlet 52, and two ends of the atomizing core assembly 102 are respectively received the first assembling hole 140 and second assembling hole 21.

That is, the thickness of the capillary gap 31 defined between the inner wall 30 and the outer wall of the sleeve 50 is 0.1 mm to 0.6 mm. Within this numerical range, the capillary gap 31 has a strong capillary action, which is beneficial for the e-liquid to be guided to the atomizing core assembly 102 along the capillary gap 31 for atomizing.

In some embodiments, referring to FIG. 3 and FIG. 4, the inner wall 30 is connected to the cover 14 and/or the cylinder 12.

That is, the thickness of the non-capillary gap 35 is greater than that of the capillary gap 31.

The capillary gap 31 may have a significant capillary action, and the e-liquid below the level of the liquid inlet 52 could be guided to the liquid inlet 52 by the capillary action. The non-capillary gap 35 may have no capillary action or has an insignificant capillary action. The thickness of the non-capillary gap 35 is quite large, the e-liquid could easily enter the non-capillary gap 35.

The plurality of first wall 34 and the plurality of second wall 36 are in a cylindrical integrated structure. Furthermore, a plurality of liquid inlets 52 are evenly arranged on the outer wall of the atomizing core assembly 102. The e-liquid could be evenly guided to the plurality of liquid inlets 50 along the capillary gap 31 between the inner wall 30 and the outer wall of the atomizing core assembly 102, thereby improving liquid inletting process stability of the atomizing core assembly 102 and improving the atomizing efficiency of the atomizer 100.

Furthermore, one end of the first wall 34 facing the base 20 protrudes out of the second wall 36, and the notch 33 is defined between the second wall 36 and portions of two adjacent first walls 34 protruding out of the second wall 36. The gap 32 is defined between the first wall 34 and the base 20, the notch 33 is used to facilitate the e-liquid to enter the non-capillary gap 35 and the capillary gap 31, thereby improving the liquid inlet efficiency.

In other words, the outer wall of the sleeve 50 has a cylindrical shape, and the inner wall 30 having a cylindrical shape is sleeved on the outer periphery of the sleeve 50. The side surface of the first wall 34 facing the outer wall of the sleeve 50 is a flat surface 340, the capillary gap 31 defined between the flat surface 340 and the outer wall of the sleeve 50 is non-uniform. The side surface of the second wall 36 facing the outer wall of the sleeve 50 is a curved surface 360, the non-capillary gap 35 formed between the curved surface 360 and the outer wall of the sleeve 50 is uniform.

Specifically, the first wall 34 is corresponded to the liquid inlet 52, the capillary gap 31 is defined between the flat surface 340 and the curved surface 360. The thickness of the capillary gap 31 gradually decreases from a contacting edge where the flat surface 340 is in contact with the curved surface 360 to middle of the flat surface 340. The capillary action generated by the capillary gap 31 gradually increases from the contacting edge where the flat surface 340 is in contact with the curved surface 360 to the middle of the flat surface 340, thereby the e-liquid could easily flow into the capillary gap 31 from the non-capillary gap 35, and the e-liquid at the edge of the capillary gap 31 could easily flow to the middle of the capillary gap 31. Since the middle of the capillary gap 31 has stronger adhesion to the e-liquid, the e-liquid could enter the liquid inlet 52 by the capillary action more easily.

In this embodiment, the curved surface 360 is parallel to arc surface of the sleeve 50 to form the uniform non-capillary gap 35. The non-capillary gap 35 may have no capillary action, and the liquid level in the non-capillary gap 35 is almost consistent with the liquid level of the liquid storage cavity 120. The liquid level in the non-capillary gap 35 also changes with the change of the liquid level of the liquid storage cavity 120.

In other embodiments, the inner wall 30 has a cylindrical shape. The inner wall 30 may be connected to the base 20 or the atomizing core assembly 102. The uniform capillary gap 31 may be formed between the first wall 34 and the outer wall of the atomizing core assembly 102. A uniform non-capillary gap 35 or a non-uniform non-capillary gap 35 could be defined between the second wall 36 and the outer wall of the atomizing core assembly 102.

In other embodiments, a plurality of inner walls 30 may be arranged around the atomizing core assembly 102 at intervals, and each of the inner walls 30 corresponds to a liquid inlet 52.

Referring to FIG. 10, FIG. 11 and FIG. 12, the inner walls 30 and the cover 14 could be formed of a single piece, the inner wall 30 could be suspended in midair relative to the base 20, and a gap 32 is defined between the inner walls 30 and the base 20.

A side surface of the inner wall 30 facing the atomizing core assembly 102 comprises a capillary plane 341, a first cambered surface 343 connected to one side of the capillary plane 341 and a second cambered surface 345 connected to the other side of the capillary plane 341. The first cambered surface 343 and the second cambered surface 345 are bent inward relative to the capillary plane 341. The capillary gap 31 defined between the capillary plane 341 and the outer wall of the atomizing core assembly 102 is non-uniform. The first cambered surface 343 and the second cambered surface 345 are used to reduce fluctuation interference of the e-liquid in the liquid storage cavity 120 on the capillary gap 31, thereby reducing the fluctuation of the e-liquid due to blocking of the first cambered surface 343 and the second cambered surface 345, and reducing the interference of capillary action generated by the capillary gap 31.

The outer wall of the sleeve 50 may have a cylindrical shape, and the capillary gap 31 defined between the capillary plane 341 and the arc surface of the sleeve 50 is non-uniform. The thickness of the capillary gap 31 may gradually decrease from the edge where the capillary plane 341 is in contact with the first cambered surface 343 and the second cambered surface 345 to the middle of the capillary plane 341.

In other embodiments, the plurality of inner walls 30 may be connected to the base 20 or the atomizing core assembly 102. A uniform capillary gap 31 may be defined between the inner wall 30 and the outer wall of the atomizing core assembly 102.

Further, referring to FIG. 13, a plurality of capillary grooves 37 capable of generating capillary action are defined on side surface of the inner wall 30 facing the outer wall of the atomizing core assembly 102. The capillary grooves 37 are communicated with the capillary gap 31, and the e-liquid could be guided to the liquid inlet 52 along the capillary grooves 37 and the capillary gap 31. The capillary groove 37 could further increase a contacting area between the e-liquid and the capillary gap 31, thereby the capillary gap 31 has a stronger tension and adsorption force on a surface of the smoke liquid, and generating a stronger capillary action.

The capillary groove 37 may be defined in a straight line along the inner wall 30 from the side where the base 20 is located toward the liquid inlet 52, or the capillary groove 37 is tortuously arranged along the inner wall 30 from the side where the base 20 is located toward the liquid inlet 52.

And/or, a plurality of capillary pores 38 capable of generating capillary action are defined on the inner wall 30. The capillary pores 38 may be communicated with the capillary gaps 31, and the capillary pores 38 may be configured to guide the liquid in the liquid storage cavity 120 to the liquid inlet 52.

For example, A plurality of capillary pores 38 are fully distributed inside the inner wall 30, such that the entire inner wall 30 and the capillary gap 31 both have capillary actions, thereby increasing guiding effect of capillary action and improving the liquid guiding efficiency greatly.

The plurality of capillary pores 38 may be evenly arranged inside the inner wall 30, or the plurality of capillary pores 38 may be randomly arranged inside the inner wall 30. The plurality of capillary pores 38 could be used to guide the e-liquid to the liquid inlet 52. Besides, the plurality of capillary pores 38 also could be communicated with each other. A liquid inlet port of the capillary pore 38 could be located on the side of the inner wall 30 away from the atomizing core assembly 102. The liquid inlet port of the capillary pore 38 also could be located on the side of the inner wall 30 facing the base 20. A liquid outlet port of the capillary pore 38 could be located on the side of the inner wall 30 facing the atomizing core assembly 102, and at least part of the liquid outlet port of the capillary pore 38 could be arranged corresponding to the liquid inlet port 52.

In at least one embodiment, referring to FIG. 14, the side of the inner wall 30 facing the atomizing core assembly 102 is provided with a capillary element 39, the capillary element 39 is used to guide the e-liquid located in the liquid storage cavity 120 to the inlet aperture 52.

The capillary element 39 may be made of cotton, sponge, etc., and the capillary element 39 is capable of guiding the e-liquid at a low liquid level to the liquid inlet 52 at a high position.

As shown in FIG. 14, the capillary element 39 may be filled between the inner wall 30 and the outer wall of the atomizing core assembly 102. The capillary element 39 connected to the liquid inlet 52 extends to the bottom of the liquid storage cavity 120. In another embodiment, as shown in FIG. 15, two capillary elements 39 are disposed on one edge of the inner wall 30 and respectively arranged at two sides of the capillary gap 31 to enhance the capillary action and avoid the fluctuation influence of the e-liquid on the capillary action.

Being different from the prior art, this disclosure discloses an atomizer, a liquid storage assembly of the atomizer, and an electronic atomizing device. A liquid storage cavity is defined in a housing, the housing defines a first assembling hole, a liquid inlet of the atomizing core assembly assembled in the first assembling hole is arranged in the liquid storage cavity. An inner wall is arranged in the liquid storage cavity. A capillary gap capable of generating capillary action is defined between the inner wall and an outer wall of the assembled atomizing core assembly. The inner wall corresponds to the liquid inlet. The capillary gap communicates with the liquid inlet. When liquid level in the liquid storage cavity is lower than the position of the liquid inlet, the liquid in the liquid storage cavity can enter the liquid inlet along the capillary gap by capillary action. E-liquid can enter the liquid inlet and is able to be atomized by the atomizing core assembly, thereby improving the utilization rate of the liquid in the liquid storage cavity, and reducing the residual quantity of the liquid in the liquid storage cavity, and a risk of dry burning of the atomizing core assembly also can be avoided. Therefore, in the present disclosure, the liquid below the liquid inlet of the atomizing core assembly can be guided to the liquid core assembly, the utilization rate of liquid in the liquid storage cavity can be improved, and the risk of dry burning of the atomizer can also be effectively reduced.

Another kind of electronic atomizing device 300 is further provided in the present disclosure. With reference to FIGS. 16-18. FIG. 16 is a structural schematic view of the electronic atomizing device 300 according to another embodiment of the present disclosure. FIG. 17 is a lateral structural schematic view of an atomizer of the electronic atomizing device 300 in FIG. 16. FIG. 18 is a first cross-sectional structural schematic view of the atomizer in direction VIII-VIII in FIG. 17.

Like the electronic atomizing device 300 illustrated in FIG. 1, the electronic atomizing device 300 may include an atomizer 100 and a body assembly 200 connected to the atomizer 100. The atomizer 100 may be used for storing atomizable material and atomizing the atomizable material to form smoke or vapor that can be inhaled by a person. The body assembly 200 may be used to supply power to the atomizer 100 for atomizing the atomizable material and forming smoke. The body assembly 300 may also be referred to as power supply. The atomizable material may be liquid matrix such as e-liquid, liquid medicine, etc.

The atomizer 100 may include housing 10. As illustrated in FIG. 19, FIG. 19 is an axial side structural schematic view of a housing 10 of the atomizer 100 in FIG. 17. Specifically, a liquid storage cavity 120 is defined in the housing 10. The housing 10 defines the first assembling hole 140. The first assembling hole 140 is used to receive the end of the atomizing core assembly 102.

The housing 10 may include an inner wall 30. The atomizer 100 may include an outer wall 54. The outer wall 54 is at least partially arranged within the inner wall 30. Namely, the outer wall 54 is at least partially arranged radially inside the inner wall 30.

In some embodiments, the inner wall 30 of the housing 10 may be eliminated, the outer wall 54 and the housing 10 are formed of a single piece, and sever as the inner wall 30 of the housing 10. In this case, the housing 10 and the outer wall 54 jointly define the liquid storage cavity 120.

The atomizing core assembly 102 is arranged within the housing 10 and at least partially arranged within the outer wall 54. Namely, the outer wall 54 at least partially surrounds the atomizing core assembly 102. As illustrated in FIG. 20, the outer wall 54 may define a first liquid inlet 541 or a plurality of first liquid inlets 541. The atomizing core assembly 102 includes a sleeve 50, and the sleeve 50 is configured to define a plurality of fluid passage holes 502. The plurality of fluid passage holes 502 may be distributed circumferentially in the sleeve 50. The sleeve 50 is at least partially arranged radially inside the outer wall 54, and configured to jointly define a capillary gap 31 with the outer wall 54. Each of the first liquid inlet 541 and the fluid passage hole 502 is connected to the capillary gap 31, and define a fluid path from any of the plurality of fluid passage holes 502 directly through the capillary gap 31 to the first liquid inlet 541. The fluid path is continuous fluid path formed by the capillary gap 31. The fluid path is from any of the fluid passage holes 502 to the first liquid inlet 541.

In the related art, when the amount of oil in the liquid storage cavity 120 drops to, for example, below half, in case the electronic atomizing device 300 is placed on its side, the first liquid inlet 541 of the atomizing core assembly 102 may be directly exposed to the air. The cavity in the liquid storage cavity 120 may easily form a pressure equilibrium with a gas channel and the external atmosphere. The oil may then continuously flow through the first liquid inlet 541 exposed to the air, resulting in oil leakage.

However, in the present disclosure, by setting a flow path formed by the capillary gap 31, surface tension and wall surface viscous resistance preventing oil flow both exit between the capillary gap 31 and the first liquid inlet 541. The surface tension and the wall viscous resistance may work together to trap the oil within the capillary gap 31, thereby preventing the first liquid inlet 541 from being directly exposed to the air. This maintains a negative pressure within the liquid storage cavity 120, creating a pressure difference between the inside and outside of the atomizing core assembly 102, so as to hinder the continuous flow of the oil into the atomizing core assembly 102 and prevent the oil leakage.

Specifically, when the electronic device 300 is placed on its side, the oil inside the atomizing core assembly 102 may flow from at least one of the fluid passage holes 502 currently at a lower position, then enter the capillary gap 31, and be guided by the capillary gap 31 to the first liquid inlet 501. The surface tension of the oil around the first liquid inlet 501 and the wall viscous resistance of the capillary gap 31 may thus prevent oil leakage through the first liquid inlet 501.

In the present embodiment, as illustrated in FIG. 19, the housing 10 includes a cylinder 12 and the inner wall 30 connected by an end plate 122. The cylinder 12, the inner wall 30 and the end plate 122 of the housing 10 together defines the liquid storage cavity 120. As illustrated in FIG. 18, the atomizer 100 includes a base 20. The base 20 is arranged on the end of the cylinder 12 opposite to the end plate 122. The cylinder 12 and the base 20 cooperatively define the liquid storage cavity 120 120. The liquid storage cavity 120 120 is used for storing or accommodating the atomizable material, such as oil. The liquid storage cavity 120 may have a shape of an annular cavity, but the shape of the liquid storage cavity 120 is not limited in the present disclosure.

The housing 10 also defines the first assembling hole 140. The first assembling hole 140 is used to receive the end of the atomizing core assembly 102.

As illustrated in FIG. 18, the base 20 is arranged at the other end of the cylinder 12 opposite to the end plate 122, and is configured to cover an end of the housing 10. The base 20 is connected to the cylinder 12 in a sealing manner. The base 20 is also configured to secure the other end of the atomizing core assembly 102.

In the present embodiment, the base 20 and the cylinder 12 may be detachably connected.

The base 20 further defines an air inlet (not illustrated). The atomizer 100 includes an electrode 24 arranged in the base 20. The electrode 24 is electrically connected with the atomizing core assembly 102. The air inlet is communicated with an atomizing cavity in the atomizing core assembly 102. Air entering the atomizing cavity from the air inlet 23 can carry smoke in the atomizing cavity to a human oral cavity.

As illustrated in FIG. 17, the electronic atomizing device 300 further includes an inhaling tube 80. The inhaling tube 80 is configured to pass through the first assembly hole 140 of the housing 10 and extend into the atomizing cavity within the atomizing core assembly 102, so as to guide the smoke in the atomizing cavity into a person's oral cavity.

Specifically, as illustrated in FIG. 18, the housing 10 further includes a liquid guiding member 61. The liquid guiding member 61 may be a liquid absorbing cotton which could be used for absorbing the oil and guides the oil to the atomizing core assembly 102. One end of the liquid guiding member 61 may extend into the liquid storage cavity 120, another end of the liquid guiding member 61 may be positioned near or abutting the first liquid inlet 541. As illustrated in FIG. 18, the other end of the first liquid-absorbing member is positioned near the first liquid inlet 541, so as to guide the oil to a cavity near the first liquid inlet 541, allowing the oil to flow into the atomizing core assembly 102 through the first liquid inlet 541. The liquid guiding member 61 60 may be supported by the base 20 or the cylinder 12, which is not restricted in the present embodiment.

As illustrated in FIGS. 20-23, FIG. 20 is a perspective view of the atomizing core assembly and the outer wall of the atomizer 100 of FIG. 17. FIG. 21 is a cross-sectional perspective view of the atomizing core assembly and the outer wall in direction X-X of FIG. 20. FIG. 22 is an axial side structural schematic view of an outer wall of FIG. 20. FIG. 23 is an axial side structural schematic view of a sleeve of the atomizing core assembly in FIG. 20

As illustrated in those Figures, the outer wall 54 has a cylindrical shape. As an example, but not a limitation, the outer wall 54 has a shape of a cylinder. The outer wall 54 defines one or a plurality of first liquid inlets 541 distributed circumferentially. The number of first liquid inlets 541 may be 2, 3, 4, 6 or 8, which is not limited here.

One end of the outer wall 54 may be fixedly connected to the base 20. Optionally, the outer wall 54 completely surrounds the atomizing core assembly 102. In this way, the oil from the liquid storage cavity 120 may enter the atomizing core assembly 102 only through the first liquid inlet 541, thereby helping to prevent oil leakage. The liquid guiding member 61 may guide the oil to the first liquid inlet 541. In this way, the first liquid inlet 541 is configured to be in fluid communication with the liquid storage cavity 120.

The atomizing core assembly 102 includes a sleeve 50, a first liquid absorbing member 62, a second liquid absorbing member 63 and the atomizing member 70.

The sleeve 50 is surrounded by the outer wall 54, and the capillary gap 31 is formed between the inner side surface of the outer wall 54 and the outer side surface of the sleeve 50 that faces each other. The thickness of the capillary gap 31 ranges from 0.1 mm to 0.6 mm. Within this numerical range, the capillary gap 31 has a strong capillary action, which is beneficial for the oil to flow along the capillary gap 31. The capillary gap 31 may be an annular gap, for example, the annular gap between the inner surface of the outer wall 54 and the outer surface of the sleeve 50.

The sleeve 50 may define a plurality of second liquid inlets 501. The plurality of second liquid inlets 501 may be arranged circumferentially in the sleeve 50. Further, the plurality of second liquid inlets 501 may be arranged evenly and circumferentially in the sleeve 50. The number of the plurality of the second liquid inlets may be 3, 4, 5, 6 or more, and is not limited here. The second liquid inlet 501 may be positioned corresponding to the first liquid inlet 541. For example, the second liquid inlet may face the first liquid inlet 541, allowing the oil from the liquid storage cavity 120 to quickly pass through the second liquid inlet 501 into the atomizing core assembly 102 when the user inhales.

In some embodiments, at least a portion of the capillary gap 31 surrounds the plurality of second liquid inlets 501, so as to form a fluid path directly through the capillary gap 31 between the plurality of second liquid inlets 501. Therefore, the plurality of second liquid inlets 501 are connect through a continuous capillary gap 31. In case that the electronic atomizing device 100 is placed on its side, a second liquid inlet 501 currently at a lower height may be immersed in oil. The oil may thus pass through this second liquid inlet 501, and enter the capillary gap 31, and finally arrive at another second liquid inlet 501 at a higher height. In this way, the second liquid inlet 501 at the higher height may be prevented from being exposed to the air, and like the reason discussed above, the surface tension and the wall viscous resistance may prevent oil leakage through the second liquid inlet 501. Further, at least a portion of the capillary gap 31 may surround the plurality of fluid passage holes 502, and form a fluid path directly through the capillary gap 31 between the plurality of second liquid inlets 501 and the plurality of fluid passage holes 502. In this way, the plurality of second liquid inlets 501 and the plurality of fluid passage holes 502 may be connected by a continuous capillary gap 31. The oil passing through the plurality of fluid passage holes 502 may be guided to the second liquid inlets 501, and helps to prevent oil leakage through the second liquid inlets 501.

The first liquid absorbing member 62 is arranged between the first liquid inlet 541 and the second liquid inlet 501. The first liquid absorbing member 62 may be a liquid absorbing cotton which could be used for absorbing and guiding the oil. The first liquid absorbing member 62 may seal at least one of the first liquid inlet 541 and the second liquid inlet 501.

In some embodiments, as specifically illustrated in FIG. 23, the sleeve 50 defines a plurality of fluid passage holes 502. The fluid passage holes 502 may include a plurality of fluid passage holes 502 arranged circumferentially in the sleeve 50. The plurality of fluid passage holes 502 may be evenly distributed circumferentially. The number of the plurality of fluid passage holes 502 may be 3, 4, 5 or more, and is not limited here.

The second liquid absorbing member 63 may be arranged within or inside the sleeve 50. The second liquid absorbing member 63 may be a liquid absorbing cotton which could be used for absorbing the oil. The second liquid absorbing member 63 may be configured to seal the plurality of second liquid inlets 501, thus may directly absorb the oil passing through the plurality of second liquid inlets 501. In some embodiment, the fluid passage hole 502 may be defined in a portion of the sleeve 50 that is distal to the second liquid absorbing member 63, thus the plurality of fluid passage holes 502 are arranged to be offset from the second liquid absorbing member 63. In this way, when the electronic atomizing device 300 is placed on its side, the oil inside the sleeve 50 may be facilitated to flow from inside the sleeve 50 to the capillary gap 31, without being directly absorbed by the second liquid absorbing member 63.

The second liquid-absorbing member 63 may, for example, be in the form of a cylinder, such as a cylindrical shape. The second liquid absorbing member 63 is configured to surround the atomizing member 70.

In some embodiments, the second liquid-absorbing member 63 defines an atomizing cavity inside itself. The atomizing cavity may, for example, be a columnar cavity. The atomizing member 70 may be arranged inside the atomizing cavity and may be in contact with the second liquid-absorbing member 63. The atomizing member 70 may be a heating wire, a ceramic atomizing core or the like which could atomize the oil. The atomizing core assembly 102 may include an atomizing member bracket 72. One end of the bracket 72 is fixed to the base 20, another end of the bracket 72 is connected to the atomizing member 70. As illustrated in FIG. 18 and FIG. 21, the bracket 72 may include two supporting arms. The atomizing member 70 is mounted on the supporting arms. As mentioned above, the atomizing member 70 is configured to connect with the electrode 24, to receive electrical energy and generate heat, thereby heating the oil in the atomizing cavity to produce smoke. The inhaling tube 80 may extend into the atomizing cavity to guide the vapor or smoke generated inside the atomizing cavity to the user's mouth.

The embodiments of the present disclosure have been described in detail above. Specific examples have been used herein to explain the principles and implementation of the present disclosure. The descriptions of the embodiments are only to help understand the method of the present disclosure and core ideas. For those skilled in the art, there will have a change in the specific embodiments and the scope of present disclosure according to the idea of the present disclosure.
