The driving device 700 is further configured to drive bubble liquid in the liquid storage reservoir to be conveyed to a bubble liquid channel 530 of the film forming nozzle 500.

The liquid storage reservoir 200 is also known as a liquid storage box or a liquid storage can. The liquid storage reservoir 200 is configured to store bubble liquid. It should be understood that the bubble liquid is configured to produce bubble films, or the bubbles are called bubble films. The liquid storage reservoir 200 has a bottom portion 203 located at a bottom end of the liquid storage reservoir 200 and a top portion 204 located at a top end of the liquid storage reservoir 200. The bottom portion 203 is understood as a bottom plate of the liquid storage reservoir 200, and the top portion 204 is understood as top ends of side plates of the liquid storage reservoir 200.

As shown in FIGS. 1, 12, and 13, the film forming nozzle 500 defines a bubble liquid channel 530. In the height direction D1, the film forming nozzle 500 is mounted above the liquid storage reservoir 200, and a projection of the film forming nozzle 500 at least partially overlaps a projection of the liquid storage reservoir 200 in the height direction D1. As shown in FIGS. 1 and 2, in the height direction D1, the film forming nozzle 500 is mounted directly above the liquid storage reservoir 200, and the projection of the film forming nozzle 500 is completely within the projection of the liquid storage reservoir 200 in the height direction D1.

The bubble liquid channel 530 of the film forming nozzle 500 is communicated with the liquid storage cavity 210 of the liquid storage reservoir 200. For instance, the film forming nozzle 500 and the liquid storage reservoir 200 are connected by a liquid conveying pipe 702.

The bubble liquid channel 530 of the film forming nozzle 500 is communicated with the liquid storage cavity 210 of the liquid storage reservoir 200 through a pipeline of the liquid conveying pipe 702. The liquid conveying pipe 702 is configured to transport the bubble liquid in the liquid storage cavity 210 to the bubble liquid channel 530. The bubble liquid in the bubble liquid channel 530 is conveyed from the inlet side 510 of the film forming nozzle 500 to an outlet side 520 of the film forming nozzle 500.

The film forming nozzle 500 may be mounted on a mounting plate 706.

The film scraping body 600 is mounted on the outlet side 520 of the film forming nozzle 500 and is movable around the outlet side 520 of the film forming nozzle 500.

The film scraping body 600 is connected to a shaft 7171, and the film scraping body 600 is rotatable around the shaft 7171 or the film scraping body 600 is rotatable along with the shaft 7171. Specifically, the shaft 7171 is directly or indirectly connected to a driving motor 701 of the driving device 700, and the driving motor 701 directly or indirectly drives the shaft 7171 and the film scraping body 600 to rotate. The driving device 700 further includes a transmission piece 717 connected to the shaft 7171, and the transmission piece 717 is directly or indirectly connected to the driving motor 701. the driving motor 701 drives the transmission piece 717 to rotate and drives the shaft 7171 and the film scraping body 600 to rotate through the transmission piece 717. The driving device 700 includes one or more gears, and the transmission piece 717 is connected to one gear of the one or more gears. For instance, the transmission piece 717 is disposed on one side of the one gear, the one gear is connected to the driving motor 701, and the driving motor 701 drives the one gear to rotate. Therefore, the film scraping body 600 makes the bubble liquid in the bubble liquid channel 530 of the film forming nozzle 500 form the bubble film at the outlet side 520 of the film forming nozzle 500 when rotating around the outlet side 520 of the film forming nozzle 500.

In other optional embodiments, the driving device 700 drives the film scraping body 600 to swing.

The shaft 7171 is mounted on one side of the film forming nozzle 500. A first portion of the film scraping body 600 is connected to the shaft 7171, and a second portion of the film scraping body 600 is mounted on the outlet side 520 of the film forming nozzle 500.

As shown in FIG. 16, the film scraping body 600 includes a rotating portion 601 and a film scraping portion 602 connected to the rotating portion 601. The film scraping portion 602 is mounted on a peripheral side of the rotating portion 601. The film scraping body 600 further includes an axial hole 611 penetrating through two end surfaces of the rotating portion 601. The axial hole 611 is configured for the shaft 7171 to pass through. A portion of the shaft 7171 passes through the axial hole 611 and is connected to the transmission piece 717 to fix the rotating portion 601 between the shaft 7171 and the transmission piece 717.

As shown in FIG. 16, the film scraping portion 602 is a rod-shaped structure, and the film scraping portion 602 is roughly a cylindrical structure. It should be understood that the film scraping portion 602 may be in other shapes.

As shown in FIG. 16, at least one reinforcing rib 603 is connected between the film scraping portion 602 and the rotating portion 601, and the at least one reinforcing rib 603 increases a connection strength between the film scraping portion 602 and the rotating portion 601. For instance, a height or a thickness of the at least one reinforcing rib 603 gradually increases from one side thereof away from the rotating portion 601 to one side thereof close to the rotating portion 601. Exemplarily, the at least one reinforcing rib 603 is in a triangular structure. In other optional embodiments, the at least one reinforcing rib 603 may be in a trapezoidal structure or another structure, which is not limited thereto.

As shown in FIGS. 1, 5, 10, and 11, the fan 400 is mounted on the same side of the liquid storage reservoir 200 and the film forming nozzle 500. The fan 400 is mounted at the inlet side 510 of the film forming nozzle 500. The fan 400 and the film forming nozzle 500 are staggered in the height direction D1. The fan 400 is mounted at the inlet side 510 of the film forming nozzle 500, which is understood as being closer to the inlet side 510 of the film forming nozzle 500 than the outlet side 520 of the film forming nozzle 500 in the length direction D2 of the bubble machine 10.

The fan 400 of the present disclosure is not mounted below the film forming nozzle 500. In other words, the fan 400 is not mounted below the outlet side 520 of the film forming nozzle 500, but the fan 400 and the film forming nozzle 500 are mounted in a staggered manner. The fan 400 is mounted at the inlet side 510 of the film forming nozzle 500, so that the fan 400 is allowed to be mounted at a reasonable position of the bubble machine 10 according to needs, which improves an overall space utilization rate of the bubble machine 10 to a certain extent. For instance, the fan 400 is mounted in a middle portion of the bubble machine 10. Moreover, a size and a power of the fan 400 are determined according to needs.

The fan 400 and the liquid storage reservoir 200 are mounted side by side in the length direction D2 of the bubble machine 10, and the liquid storage reservoir 200 is close to a front end of the bubble machine 10. That is, the liquid storage reservoir 200 is located at the front end of the bubble machine 10. The fan 400 is mounted near the middle portion of the bubble machine 10.

It should be noted that if the fan is directly disposed below the film forming nozzle, the wind blown by the fan is not concentrated, such that only a part of the wind generated by the fan acts on the bubble film, and an amount of wind directly acting on the bubble film at the film forming nozzle position is limited, resulting in a large amount of waste of the wind generated by the fan.

The bubble machine 10 further includes an air duct 300, and the air conveying channel 350 of the air duct 300 is communicated with an air outlet 420 of the fan 400. Specifically, the air duct 300 and the fan 400 are connected. For instance, the air duct 300 is sleeved with the fan 400, so that the wind generated by the fan 400 is directly conveyed to the air duct 300, thereby reducing or even avoiding the waste of wind generated by the fan 400.

The air duct 300 is sleeved with the fan 400. That is, the fan 400 is plugged into the air duct 300. Specifically, the fan 400 is plugged into the air duct 300 from an air duct inlet 330 of the air duct 300, so that an air outlet 420 of the fan 400 is communicated with the air conveying channel 350 of the air duct 300, and the wind generated by the fan 400 is conveyed in the air conveying channel 350 and is conveyed to an air duct outlet 340 of the air duct 300. The, the wind is conveyed from the air duct outlet 340 to the outlet side 520 of the film forming nozzle 500 to blow the bubbles away from the film forming nozzle 500.

A portion of the fan 400 is plugged into the air duct 300. For instance, the air inlet 410 of the fan 400 is not mounted in the air duct 300, but is disposed outside the air duct 300. It is understood that the portion of the fan 400 plugged into the air duct 300 is configured as needed, which is not limited thereto.

In other optional embodiments, a portion of the air duct 300 is plugged into the fan 400.

For example, there are three first connectors 304 and three second connectors 404, all of which are mounted at intervals. Optionally, the three first connectors 304 or the three second connectors 404 are mounted at equal intervals.

In one optional embodiment, as shown in FIGS. 7-11, in order to further increase the connection stability between the housing 401 and the first duct 301, at least one clamping groove 360 is defined in an inner surface of the first duct 301, and at least one positioning structure 405 is disposed on one end of the housing 401 away from the air inlet 410 of the fan, and the at least one positioning structure 405 is plugged into the at least one clamping groove 360 from one end of the first duct 301 close to the air duct inlet 330 of the air duct 300. The at least one clamping groove 360 limits the at least one positioning structure 405, thereby increasing the connection stability between the first duct 301 and the housing 401. It should be understood that the air duct inlet 330 of the air duct 300 is disposed in the first duct 301.

The at least one clamping groove 360 includes three clamping grooves 360. Each of the three clamping grooves 360 is mounted adjacent to a corresponding one of the three first connectors 304. For instance, each of the three clamping grooves 360 is mounted below the corresponding one of the three first connectors 304 in the height direction D1 of the bubble machine 10.

It should be understood that the connection method between the fan 400 and the air duct 300 is not limited thereto.

The fan 400 and the first duct 301 are mounted in the height direction D1 of the bubble machine 10.

The air duct outlet 340 of the air duct 300 is close to or disposed on one side of the liquid storage reservoir 200 away from the fan 400. In the height direction D1, at least a portion of the air duct 300 is mounted below the liquid storage reservoir 200. The air duct outlet 340 of the air duct 300 is disposed at or close to the bottom end of the liquid storage reservoir 200 away from the film forming nozzle 500.

The air duct 300 includes the first duct 301 and a second duct 302 connected to the first duct 301. The air outlet 420 of the fan 400 is communicated with a first air conveying channel of the first duct 301, and the first duct 301 is communicated with a second air conveying channel of the second duct 302. It should be understood that the air conveying channel 350 of the air duct 300 includes the first air conveying channel of the first duct 301 and the second air conveying channel of the second duct 302. It should further be understood that the air duct inlet of the air duct 300 is defined in the first duct 301, and the air duct outlet 340 of the air duct 300 is defined in the second duct 302.

The first duct 301 and the second duct 302 are bent toward each other. For instance, the first duct 301 is approximately perpendicular to the second duct 302. Alternatively, an included angle formed by the first duct 301 and the second duct 302 is 90 degrees or close to 90 degrees, such as 89 degrees, 91 degrees, etc.

The first duct 301 is mounted on the same side of the liquid storage reservoir 200 and the film forming nozzle 500, and the first duct 301 is mounted on the inlet side 510 of the film forming nozzle 500. The first duct 301 and the film forming nozzle 500 are staggered in the height direction D1.

In the height direction D1, the second duct 302 is at least partially mounted below the liquid storage reservoir 200.

A first inclined portion 310 is disposed on one side of the first duct 301 away from the second duct 3012. The first inclined portion 310 is disposed on one end of the first duct 301 away from the fan 400. A head portion 311 of the first inclined portion 310 is closer to the second duct 302 than a tail portion 312 of the first inclined portion 310.

A second inclined portion 320 is disposed at one end of the second duct 302 away from the first duct 301, and a head portion 321 of the second inclined portion 320 is closer to the first duct 301 than a tail portion 322 of the second inclined portion 320.

An inclination direction of the first inclined portion 310 is different from an inclination direction of the second inclined portion 320. For instance, the inclination directions of the first inclined portion 310 is substantially opposite to the second inclined portion 320.

An inclination angle of the first inclined portion 310 and the inclination angle of the second inclined portion 320 are substantially the same. That is, a slope of the first inclined portion 310 and a slope of the second inclined portion 320 are substantially the same.

The one side of the liquid storage reservoir 200 away from the fan 400 defines an inclined port 220. In other words, the one side of the liquid storage reservoir 200 away from the film forming nozzle 500 defines the inclined port 220. The inclined port 220 is communicated with the air duct outlet 340. The inclined port 220 and the air duct outlet 340 jointly define a flow direction of the wind generated by the fan 400.

A third inclined portion 201 is disposed on the one side of the liquid storage reservoir 200 away from the fan 400. In the height direction D1, the third inclined portion 201 is inclined from the bottom portion 203 of the liquid storage reservoir 200 toward the top portion 204 of the liquid storage reservoir 200. A head portion of the third inclined portion 201 is closer to the fan 400 than a tail portion thereof. Optionally, the third inclined portion 201 is a part of the inclined port 220.

The third inclined portion 201 faces the second inclined portion 320, and an inclination angle of the third inclined portion 201 is the same as the inclination angle of the second inclined portion 320. The third inclined portion 201 faces the second inclined portion 320, which means that an inclination direction of the third inclined portion 201 and the inclination direction of the second inclined portion 320 are roughly the same. Thus, the second inclined portion 320 and the third inclined portion 201 jointly limit the direction of the wind generated by the fan 400.

In other optional embodiments, the inclination directions of the third inclined portion 201 is different from the inclination directions of the second inclined portion 320, and the inclination angle of the third inclined portion 201 is different from the inclination angle of the second inclined portion 320. It should be noted that the inclination direction and inclination angle of the third inclined portion 201 and the inclination direction and inclination angle of the second inclined portion 320 are set according to actual needs.

A limiting ring 303 is disposed on one end of the second duct 302 away from the first duct 301. The limiting ring 303 is mounted around the air duct outlet 340 of the air duct 300. Correspondingly, the liquid storage reservoir 200 defines a limiting groove 230 for accommodating the limiting ring 303, and the limiting ring 303 is mounted in the limiting groove 230. A side wall of the liquid storage reservoir 200 defining the limiting groove 230 is configured to limit a position of the limiting ring 303, so as to limit a position of the second duct 302.

A blocking portion 202 configured to limit the position of the second duct 302 is disposed on the bottom portion 203 of the liquid storage reservoir 200. The blocking portion 202 is adjacent to one side or two sides of the second duct 302 to limit the portion of the second duct 302 in the width direction D3 of the bubble machine 10. Thus, the second duct 302 is at least limited by both the blocking portion 202 and the side wall defining the limiting groove 230. The embodiment of the present disclosure utilizes structural features of the liquid storage reservoir 200, which not only plays a role in storing the bubble liquid, but also limit the position of the air duct 300, so as to maintain the stability of the air duct 300 without the need for additional fastening structures to limit the air duct 300.

In the width direction D2, the second duct 302 does not exceed the liquid storage reservoir 200. For instance, one end of the second duct 302 away from the first duct 301 is roughly flush with or roughly overlaps with the one side of the liquid storage reservoir 200 away from the fan 400. The inclined port 220 of the liquid storage reservoir 200 is communicates with the air duct outlet 340 to jointly define the blowing direction of the wind generated by the fan 400, thereby effectively utilizing matching relationships between various components to improve the overall space utilization rate of the bubble machine 10. Compared with a care where the second duct 302 is completely disposed below the liquid storage reservoir 200, the air duct outlet 340 is disposed in front of the liquid storage reservoir 200 and away from the fan 400, a space occupied by the second duct 302 effectively reduces, making the matching relationship between the various components of the bubble machine 10 more compact.

Specifically, the liquid storage reservoir 200 further includes a baffle 205 disposed on its top portion 204 of the liquid storage reservoir 200, and the baffle 205 is disposed on the one side of the liquid storage reservoir 200 close to the fan 400, and the baffle 205 is closer to the fan 400 than the outlet side 520 of the film forming nozzle 500. The baffle 205 prevents the bubble liquid flowing out of the outlet side 520 of the film forming nozzle 500 from entering the fan 400.

In other optional embodiments, the second duct 302 passes through the liquid storage reservoir 200.

In other optional embodiments, in the height direction D1 of the bubble machine 10, the air duct 300 is at least partially disposed on the peripheral side of the liquid storage reservoir 200. That is, in the width direction D3 of the bubble machine 10, the air duct 300 is at least partially mounted aligned with the liquid storage reservoir 200.

In other optional embodiments, both the fan 400 and the first duct 301 are mounted in the length direction D2 or the width direction D3 of the bubble machine 10.

In other optional embodiments, the liquid storage reservoir 200 may be disposed above the film forming nozzle 500 so that the bubble liquid in the liquid storage reservoir 200 flows to the film forming nozzle 500 under gravity.

As shown in FIGS. 1, 2, and 12-14, the driving device 700 not only drives the film scraping body 600 to move, but also drives the bubble liquid in the liquid storage reservoir 200 to be conveyed to the bubble liquid channel 530 of the film forming nozzle 500. That is, the driving device 700 drives both the film scraping body 600 and the bubble liquid. Compared with a method of providing two driving devices to drive the film forming nozzle 500 and the bubble liquid respectively, the present disclosure only provides one driving device to save the space and costs.

The bubble machine 10 includes the liquid conveying pipe 702, and the pipeline of the liquid conveying pipe 702 communicates the liquid storage cavity 210 of the liquid storage reservoir 200 and the bubble liquid channel 530 of the film forming nozzle 500. The driving device 700 includes one or more rollers 703, and during the rotation of the one or more rollers 703, the liquid conveying pipe 702 is squeezed to drive the bubble liquid in the liquid storage reservoir 200 to be conveyed to the bubble liquid channel 530 of the film forming nozzle 500.

Optionally, an outer surface of each roller 703 is generally smooth. Optionally, the outer surface of each roller 703 fits the outer surface of the liquid conveying pipe 702, and each roller 703 squeezes the liquid conveying pipe 702 to deform the liquid conveying pipe 702, so that a pipeline shape of the liquid conveying pipe 702 changes. It should be understood that the liquid conveying pipe 702 is able to be deformed under an action of each roller 703. The liquid conveying pipe 702 is made of a flexible material.

Optionally, a portion where the outer surface of each roller 703 fits the outer surface of the liquid conveying pipe 702 is an arc structure, such as a circular arc structure.

Optionally, each roller 703 includes a first roller body 7031 and a second roller body 7032 connected to the first roller body 7031. Along the rotation direction D4 of each roller 703, the first roller body 7031 is connected to a peripheral surface of the second roller body 7032. Along the rotation direction D4 of each roller 703, an outer surface of the first roller body 7031 and an outer surface of the second roller body 7032 are arc-shaped, and the outer surface of the first roller body 7031 and the outer surface of the second roller body 7032 are in contact with the outer surface of the liquid conveying pipe 702.

In each roller 703, a size of the first roller body 7031 is less than a size of the second roller body 7032, and along the rotation direction D4 of each roller 703, the first roller body 7031 is in front of the second roller body 7032. In each roller 703, the size of the first roller body 7031 is less than the size of the second roller body 7032, which means that a height of the first roller body 7031 is less than a height of the second roller body 7032, and/or a diameter of the first roller body 7031 is less than a diameter of the second roller body 7032.

The second roller body 7032 of each roller 703 is hollow. Since the size of the second roller body 7032 of each roller 703 is greater than the size of the first roller body 7031 of each roller 703, even if the second roller body 7032 of each roller 703 is hollow, the second roller body 7032 of each roller 703 has sufficient strength. Thus, a weight of the second roller body 7032 of each roller 703 is reduced, which is conducive to driving the driving motor 701 of the driving device 700.

The one or more gears of the driving device 700 include a first gear 711 and a second gear 712. The driving motor 701 is configured to drive the first gear 711 and the second gear 712 to rotate. It should be understood that the driving motor 701 directly or indirectly drives the first gear 711 and the second gear 712 to rotate. The driving motor 701 directly or indirectly drives the first gear 711 and the second gear 712 through a driving gear 713 disposed on the output shaft 7011 thereof.

The one or more rollers 703 are mounted on one side of the first gear 711. When the one or more rollers 703 include a plurality of rollers 703, the plurality of rollers 703 are mounted on the same side of the first gear 711 and are mounted at intervals.

The second gear 712 is connected to the film scraping body 600. The second gear 712 is able to drive the film scraping body 600 to rotate during rotation.

The driving device 700 further includes a fourth gear 714, a fifth gear 715, and a sixth gear 716. The driving gear 713 is meshed with the fourth gear 714, the fourth gear 714 is meshed with the first gear 711, the first gear 711 is meshed with the fifth gear 715, the fifth gear 715 is meshed with the sixth gear 716, and the sixth gear 716 is meshed with the second gear 712. When the driving motor 701 is powered on, or in other words, when the driving motor 701 is in a working state, the output shaft 7011 is driven to rotate, thereby driving the driving gear 713 to rotate. Then, the driving gear 713 sequentially drives the fourth gear 714, the first gear 711, the fifth gear 715, the sixth gear 716, and the second gear 712 to rotate. During the rotation of the first gear 711, the plurality of rollers 703 mounted on one side thereof are driven to rotate together, thereby squeezing the liquid conveying pipe 702 and driving the bubble liquid in the liquid storage reservoir 200 to the film forming nozzle 500. Further, one side of the second gear 712 of the embodiment of the present disclosure is connected to the transmission piece 717, and during the rotation of the second gear 712, the shaft 7171 fixed on the transmission piece 717 and the film scraping body 600 are driven to rotate together to form the bubble films.

The plurality of rollers 703 include at least three rollers. The at least three rollers 703 are mounted at equal intervals along a rotating shaft 704 of the first gear 711, and a portion of the liquid conveying pipe 702 is mounted around the rotating shaft 704 and fits with the at least three rollers 703.

In other optional embodiments, each roller is a cylindrical structure, a conical structure, or a truncated cone. As shown in FIG. 15, in another optional embodiment, each roller 703b is the cylindrical structure. Other structures shown in FIG. 15, such as the first gear 711 and the rotating shaft 704, are the same as the first gear 711 and the rotating shaft 704 shown in FIG. 14.

It should be noted that in actual applications, when the bubble liquid reaches the film forming nozzle 500, the film scraping body 600 rotates to scrape the bubble liquid flowing to the outlet side of the film forming nozzle to form the bubble film. When the bubble liquid does not reach the film forming nozzle 500, the rotation of the film scraping body 600 is invalid, which wastes electricity. Based on this, in the process of the driving motor 701 driving the at least three rollers 703 and the shaft 7171, the driving motor 701 first drives the at least three rollers 703 and then drives the shaft 7171. It is understood that a driving order of the driving motor 701 is: driving the at least three rollers 703 to rotate first, and then driving the shaft 7171. It is understood that the driving motor 701 drives the at least three rollers 703 before driving the shaft 7171. It is also understood that the shaft 7171 is driven by the first gear 711 where the at least three rollers 703 are located, and there is at least one gear between the first gear 711 and the shaft 7171. It should be understood that the film scraping body 600 is connected to the shaft 7171, and the driving motor 701 drives the film scraping body 600 after driving the at least three rollers 703, or drives the at least three rollers 703 before driving the film scraping body 600.

In other optional embodiments, the driving motor 701 may use different paths to drive the at least three rollers 703 and the shaft 7171 respectively, such as the driving motor 701 uses two sets of gear sets to drive the at least three rollers 703 and the shaft 7171 respectively.
