Description

Technical Field

[0001] The present application relates to the technical field of bubble blowing, and in particular to a bubble machine. Background Art

[0002] A bubble machine is a machine that can be used to generate bubbles, which can not only be used as daily entertainment, but also can be used to create a certain atmosphere for the stage.

[0003] The Chinese utility model patent with the announcement number: CN209137981U discloses a smoke bubble machine, including an oil pump for conveying smoke oil, a heater connected to the oil pump through an oil delivery pipe, a smoke collection box for collecting smoke generated by the heater, a mist bubble nozzle connected to the smoke collection box and having a nozzle opening, an infusion pump for conveying bubble water to the nozzle opening of the mist bubble nozzle, a film brushing rod that can be hung at the nozzle opening to form a bubble film, and a brush rod driver that drives the film brushing rod to reciprocate at the nozzle opening. The smoke bubble machine is provided with a bubble delivery fan located below the mist nozzle, and the blowing direction of the bubble delivery fan forms an angle with the spraying direction of the mist nozzle.

[0070] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way constitutes a limitation on the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present application.

[0071] Reference to "embodiment" or "embodiment mode" in this text means that a particular feature, structure, or characteristic described in connection with the embodiment or embodiment mode may be included in at least one embodiment of the present application. The phrase appears at various positions in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0072] As Figures 1 to 11 shown, an embodiment of the present application provides a bubble machine 10, which has a height direction D1, a length direction D2, and a width direction D3.

[0073] Exemplarily, the height direction D1 of the bubble machine 10 is substantially perpendicular to the length direction D2 and the width direction D3 of the bubble machine 10, and the length direction D2 and the width direction D3 of the bubble machine 10 are substantially perpendicular.

[0074] Exemplarily, the dimension of the bubble machine 10 along the length direction D2 is not less than the dimension of the bubble machine 10 along the width direction D3, such as the dimension of the bubble machine 10 along the length direction D2 is greater than the dimension of the bubble machine 10 along the width direction D3.

[0075] Exemplarily, the bubble machine 10 includes a liquid storage 200, a film-forming nozzle 500, a film-brushing body 600, and a bubble-sending fan 400. It should be understood that the bubble machine 10 in the embodiments of the present application may further include other components. In an alternative embodiment of the present application, as Figures 12 to 14 shown, the bubble machine 10 further includes a driving device 700, which is used to drive the movement of the film-brushing body, and the driving device 700 is also used to drive the bubble liquid in the liquid storage to be conveyed to the bubble channel 530 of the film-forming nozzle.

[0076] Among them, the liquid storage 200 can also be referred to as a liquid storage box or a liquid storage tank, and the liquid storage 200 is used to store bubble liquid. It should be understood that the bubble liquid is used to generate a bubble film, or the bubble is called a bubble film. The liquid storage 200 has a bottom 203 at the bottom end and a top 204 at the top end. Among them, the bottom 203 can be understood as the bottom plate of the liquid storage 200, and the top 204 can be understood as the top end of the side plate of the liquid storage 200. The bottom end of the side plate of the liquid storage 200 is connected to the bottom plate of the liquid storage 200 to enclose a liquid storage tank 210. Or rather, the liquid storage 200 has a liquid storage tank 210. The opening of the liquid storage tank 210 faces from the bottom 203 of the liquid storage 200 towards the top 204 of the liquid storage 200, or rather, the opening of the liquid storage tank 210 is located at the top 204 of the liquid storage 200.

[0077] As Figure 1 , and in combination with Figure 12 and Figure 13 shown, the film-forming nozzle 500 has a bubble channel 530. In the height direction D1, the film-forming nozzle 500 is arranged above the liquid storage 200, and the projections of the film-forming nozzle 500 and the liquid storage 200 in the height direction D1 at least partially overlap. Exemplarily, as Figure 1 and Figure 2 shown, in the height direction D1, the film-forming nozzle 500 is arranged directly above the liquid storage 200, and the projection of the film-forming nozzle 500 in the height direction D1 is completely located within the projection of the liquid storage 200 in the height direction D1.

[0078] Exemplarily, the bubble channel 530 of the film-forming nozzle 500 is communicated with the liquid storage tank 210 of the liquid storage 200. Exemplarily, the film-forming nozzle 500 and the liquid storage 200 are connected by an infusion tube 702. For example, the inlet side 510 of the film-forming nozzle 500 is connected to the infusion tube 702, and a part of the infusion tube 702 is placed in the liquid storage tank 210. The bubble channel 530 of the film-forming nozzle 500 is communicated with the liquid storage tank 210 of the liquid storage 200 through the pipeline of the infusion tube 702. The infusion tube 702 can transport the bubble liquid located in the liquid storage tank 210 to the bubble channel 530, and the bubble liquid in the bubble channel 530 can be transmitted from the inlet side 510 of the film-forming nozzle 500 to the outlet side 520 of the film-forming nozzle 500.

[0079] Exemplarily, the film-forming nozzle 500 can be installed on the mounting plate 706.

[0080] As Figure 1 and Figure 2 , and in combination with Figure 12 and Figure 13As shown, the film brushing body 600 is installed on the outlet side 520 of the film forming nozzle 500 and can move on the outlet side 520 of the film forming nozzle 500. The film brushing body 600 can also be referred to as a film covering body or a film brushing rod. During the movement of the film brushing body 600, bubble liquid can form a bubble film on the outlet side 520 of the film forming nozzle 500. Specifically, during the movement of the film brushing body 600, bubble liquid located in the bubble channel 530 of the film forming nozzle 500 can form a bubble film.

[0081] Exemplarily, the film brushing body 600 is connected to a driving device 700, and the driving device 700 can drive the film brushing body 600 to move. In an optional embodiment of the present application, the driving device 700 can drive the film brushing body 600 to rotate. The film brushing body 600 is connected to a shaft body 7171, and the film brushing body 600 can rotate around the shaft body 7171 or the film brushing body 600 can rotate together with the shaft body 7171. Specifically, the shaft body 7171 is directly or indirectly connected to a motor 701 in the driving device 700, and the motor 701 can directly or indirectly drive the shaft body 7171 and the film brushing body 600 to rotate. Exemplarily, the driving device 700 further includes a transmission member 717 connected to the shaft body 7171. The transmission member 717 is directly or indirectly connected to the motor 701. The motor 701 drives the transmission member 717 to rotate and drives the shaft body 7171 and the film brushing body 600 to rotate through the transmission member 717. Exemplarily, the driving device 700 includes one or more gears. The transmission member 717 is connected to one of the gears. For example, the transmission member 717 is disposed on one side of a gear, and the gear is connected to the motor 701. The motor 701 drives the gear to rotate. Thus, during the rotation of the film brushing body 600 on the outlet side 520 of the film forming nozzle 500, bubble liquid in the bubble channel 530 of the film forming nozzle 500 can form a bubble film on the outlet side 520 of the film forming nozzle 500.

[0082] In other optional embodiments, the driving device 700 can drive the film brushing body 600 to swing.

[0083] Wherein, the shaft body 7171 is disposed on the side of the film forming nozzle 500. Wherein, a part of the film brushing body 600 is connected to the shaft body 7171, and another part of the film brushing body 600 is disposed on the outlet side 520 of the film forming nozzle 500.

[0084] Exemplarily, as Figure 16 shown, the film brushing body 600 includes a rotating part 601 and a film brushing part 602 connected to the rotating part 601. The film brushing part 602 is disposed on the circumferential side of the rotating part 601. The film brushing body 600 further includes a shaft hole 611 penetrating through both end faces of the rotating part 601. The shaft hole 611 is used for the shaft body 7171 to pass through. A part of the shaft body 7171 passes through the shaft hole 611 and is connected to the transmission member 717 to fix the rotating part 601 between the shaft body 7171 and the transmission member 717.

[0085] Please continue to refer to Figure 16 , the film brushing part 602 has a rod-shaped structure, and the film brushing part 602 is generally a cylindrical structure. It should be understood that the film brushing part 602 can also be of other shapes.

[0086] Please continue to refer to Figure 16 , one or more reinforcing ribs 603 are connected between the film brushing part 602 and the rotating part 601, and the reinforcing ribs 603 can increase the connection strength between the film brushing part 602 and the rotating part 601. Further, the height or thickness of the reinforcing ribs 603 gradually increases from the side away from the rotating part 601 to the side close to the rotating part 601. Exemplarily, the reinforcing ribs 603 have a triangular structure. In other alternative embodiments, the reinforcing ribs 603 can also have a trapezoidal or other shaped structure, and the embodiments of the present application do not limit the shape of the reinforcing ribs 603.

[0087] As Figures 1 to 5 , Figure 10 and Figure 11 shown, the bubble sending fan 400 is arranged on the same side of the liquid storage 200 and the film forming nozzle 500, and is arranged on the inlet side 510 of the film forming nozzle 500. The bubble sending fan 400 and the film forming nozzle 500 are arranged offset in the height direction D1. It can be understood that the bubble sending fan 400 being arranged on the inlet side 510 of the film forming nozzle 500 can be 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.

[0088] In the embodiment of the present application, the bubble sending fan 400 is not arranged below the film forming nozzle 500, or rather, the bubble sending fan 400 is not arranged below the outlet side 520 of the film forming nozzle 500. Instead, the bubble sending fan 400 and the film forming nozzle 500 are arranged offset, and the bubble sending fan 400 is arranged on the inlet side 510 of the film forming nozzle 500. Thus, the bubble sending fan 400 in the embodiment of the present application can be arranged at a reasonable position of the bubble machine 10 according to requirements, and can improve the overall space utilization rate of the bubble machine 10 to a certain extent. For example, the bubble sending fan 400 can be arranged at the middle position of the bubble machine 10. Moreover, the bubble sending fan 400 in the embodiment of the present application can set its size and power according to requirements.

[0089] Exemplarily, the bubble sending fan 400 and the liquid storage 200 are arranged side by side in the length direction D2 of the bubble machine 10. The liquid storage 200 is close to the front end of the bubble machine 10, or the liquid storage 200 is located at the front end of the bubble machine 10. The bubble sending fan 400 can be arranged at a position close to the middle of the bubble machine 10.

[0090] It should be noted that if the bubble-delivery fan is directly arranged below the film-forming nozzle, the wind blown by the bubble-delivery fan is dispersed, resulting in only a part of the wind generated by the bubble-delivery fan acting on the bubble film. The amount of wind directly acting on the bubble film at the position of the film-forming nozzle is limited, leading to a large waste of the wind generated by the bubble-delivery fan.

[0091] Exemplarily, the bubble machine 10 further includes a bubble-delivery air duct body 300. The air delivery duct 350 of the bubble-delivery air duct body 300 is communicated with the air outlet 420 of the bubble-delivery fan 400. Exemplarily, the bubble-delivery air duct body 300 and the bubble-delivery fan 400 are connected. For example, the bubble-delivery air duct body 300 and the bubble-delivery fan 400 are sleeved with each other, so as to directly convey the wind generated by the bubble-delivery fan 400 into the bubble-delivery air duct body 300, thereby reducing or even avoiding the waste of the wind generated by the bubble-delivery fan 400.

[0092] Exemplarily, the bubble-delivery air duct body 300 sleeves the bubble-delivery fan 400, or the bubble-delivery fan 400 is inserted into the bubble-delivery air duct body 300. Specifically, the bubble-delivery fan 400 is inserted into the bubble-delivery air duct body 300 from the air duct inlet 330 of the bubble-delivery air duct body 300, so that the air outlet 420 of the bubble-delivery fan 400 is communicated with the air delivery duct 350 of the bubble-delivery air duct body 300. The wind generated by the bubble-delivery fan 400 is conveyed in the air delivery duct 350 to the air duct outlet 340 of the bubble-delivery air duct body 300, and is conveyed from the air duct outlet 340 to the outlet side 520 of the film-forming nozzle 500 to blow the bubble film separated from the film-forming nozzle 500.

[0093] Exemplarily, a part of the bubble-delivery fan 400 is inserted into the bubble-delivery air duct body 300. For example, the air inlet 410 of the bubble-delivery fan 400 is not arranged in the bubble-delivery air duct body 300 but outside the bubble-delivery air duct body 300. It can be understood that the amount of the bubble-delivery fan 400 inserted into the bubble-delivery air duct body 300 can be set as needed, and the embodiments of the present application do not make limitations.

[0094] In other alternative embodiments, a part of the bubble-delivery air duct body 300 is inserted into the bubble-delivery fan 400.

[0095] Such as Figures 7 to 11As shown, in order to increase the connection stability between the bubble delivery duct body 300 and the bubble delivery fan 400, the bubble delivery duct body 300 includes a first connector 304, and the bubble delivery fan 400 includes a second connector 404. The bubble delivery fan 400 is inserted into the bubble delivery duct body 300, and the first connector 304 and the second connector 404 are connected to define the relative positional relationship between the bubble delivery duct body 300 and the bubble delivery fan 400.

[0096] Exemplarily, the bubble delivery fan 400 includes a fan housing 401, a fan blade 402 disposed within the fan housing 401, and a fan motor 403 connected to the fan blade 402. The fan motor 403 is configured to drive the fan blade 402 to rotate within the fan housing 401 to generate wind. Exemplarily, the fan blade 402 is disposed near the air inlet 410, and the fan motor 403 is disposed near the air outlet 420.

[0097] Exemplarily, the bubble delivery duct body 300 includes a first duct 301 that is sleeved with the fan housing 401, and the inner surface of the first duct 301 is in contact with the outer surface of the fan housing 401.

[0098] The first connector 304 is disposed on the first duct 301. Exemplarily, the first connector 304 is disposed at one end of the first duct 301.

[0107] Exemplarily, the first pipe body 301 and the second pipe body 302 are bent relative to each other, such as the first pipe body 301 and the second pipe body 302 being substantially perpendicular to each other, or the included angle formed by the first pipe body 301 and the second pipe body 302 being 90 degrees or close to 90 degrees, such as 89 degrees, 91 degrees, etc.

[0108] Exemplarily, the first pipe body 301 is disposed on the same side of the liquid storage 200 and the film forming nozzle 500, and the first pipe body 301 is disposed on the inlet side 510 of the film forming nozzle 500, and the first pipe body 301 and the film forming nozzle 500 are disposed offset from each other in the height direction D1.

[0109] Exemplarily, in the height direction D1, at least a part of the second pipe body 302 is disposed below the liquid storage 200.

[0110] Exemplarily, a first inclined portion 310 is provided on a side of the first pipe body 301 away from the second pipe body 302, and the first inclined portion 310 is located at an end of the first pipe body 301 away from the bubble sending fan 400, and a first end position 312 of the first inclined portion 310 is closer to the second pipe body 302 than its first start position 311.

[0112] Exemplarily, the inclination directions of the first inclined portion 310 and the second inclined portion 320 are different, such as the inclination directions of the first inclined portion 310 and the second inclined portion 320 being substantially opposite.

[0113] Exemplarily, the inclination angles of the first inclined portion 310 and the second inclined portion 320 are substantially the same, or the slopes of the first inclined portion 310 and the second inclined portion 320 are substantially the same.

[0114] An inclined port 220 is provided on a side of the liquid storage 200 away from the bubble sending fan 400, or an inclined port 220 is provided on a side of the liquid storage 200 away from the film forming nozzle 500, and the inclined port 220 is communicated with the air duct outlet 340, and the inclined port 220 and the air duct outlet 340 jointly define the flow direction of the wind generated by the bubble sending fan 400.

[0115] On one side of the liquid storage 200 away from the bubble sending fan 400, a third inclined portion 201 is provided. In the height direction D1, the third inclined portion 201 is inclined from the bottom 203 of the liquid storage 200 towards the top 204 of the liquid storage 200. The third starting position of the third inclined portion 201 is closer to the bubble sending fan 400 than its third ending position. Exemplarily, the third inclined portion 201 is a part of the inclined opening 220.

[0116] Exemplarily, the third inclined portion 201 and the second inclined portion 320 are oppositely arranged, and the inclination degrees of the third inclined portion 201 and the second inclined portion 320 are the same. The opposite arrangement of the third inclined portion 201 and the second inclined portion 320 can be understood as that the inclination directions of the third inclined portion 201 and the second inclined portion 320 are generally the same. Thus, the second inclined portion 320 and the third inclined portion 201 in the embodiment of the present application can jointly limit the direction of the wind generated by the bubble sending fan 400.

[0117] In other alternative embodiments, the inclination directions of the third inclined portion 201 and the second inclined portion 320 are different, and the inclination degrees of the third inclined portion 201 and the second inclined portion 320 are different. It should be noted that the inclination directions and inclination degrees of the third inclined portion 201 and the second inclined portion 320 can be set according to actual needs.

[0118] Exemplarily, a limiting ring 303 is provided at one end of the second pipe body 302 away from the first pipe body 301. The limiting ring 303 is arranged around the air duct outlet 340 of the bubble sending air duct body 300. Correspondingly, the liquid storage 200 is provided with a limiting groove 230 for placing the limiting ring 303, and the limiting ring 303 is arranged in the limiting groove 230. The wall of the liquid storage 200 used to form the limiting groove 230 can limit the limiting ring 303, thereby being able to limit the second pipe body 302.

[0119] Exemplarily, a blocking portion 202 for limiting the second pipe body 302 is further provided at the bottom 203 of the liquid storage 200. The blocking portion 202 can be arranged on one side or both sides of the second pipe body 302 to limit the second pipe body 302 in the width direction D3 of the bubble machine 10. Thus, the second pipe body 302 is at least doubly limited by the blocking portion 202 and the wall of the limiting groove 230. The embodiment of the present application utilizes the structural characteristics of the liquid storage 200, which not only plays the role of storing the bubble liquid, but also can limit the bubble sending air duct body 300 to maintain the stability of the bubble sending air duct body 300 without the need to additionally adopt a fastening structure to overly limit the bubble sending air duct body 300.

[0120] Exemplarily, in the width direction D2, the second pipe body 302 does not protrude outside the liquid storage 200. For example, the end of the second pipe body 302 away from the first pipe body 301 is substantially flush with, or substantially coincides with, the side of the liquid storage 200 away from the bubble sending fan 400. In the embodiment of the present application, the inclined port 220 of the liquid storage 200 is also communicated with the air duct outlet 340 to jointly define the blowing direction of the wind generated by the bubble sending fan 400, effectively utilizing the cooperation relationship between the structural members and improving the overall space utilization rate of the bubble machine 10. Compared with completely arranging the second pipe body 302 below the liquid storage 200 and arranging the air duct outlet 340 in front of the liquid storage 200, or on the outer side away from the bubble sending fan 400, the occupation of the overall space of the bubble machine 10 by the second pipe body 302 can be effectively reduced, making the arrangement relationship between the components of the bubble machine 10 more compact.

[0121] Exemplarily, the liquid storage 200 further includes a baffle 205 provided on its top 204, and the baffle 205 is provided on the side of the liquid storage 200 close to the bubble sending fan 400, and the baffle 205 is closer to the bubble sending fan 400 than the outlet side 520 of the film forming nozzle 500. The setting of the baffle 205 prevents the bubble liquid flowing out from the outlet side 520 of the film forming nozzle 500 from entering the side of the bubble sending fan 400.

[0122] In other alternative embodiments, the second pipe body 302 penetrates through the liquid storage 200.

[0123] In other alternative embodiments, in the height direction D1 of the bubble machine 10, at least a part of the bubble sending air duct body 30 is arranged on the periphery of the liquid storage 200; or it can be understood that in the width direction D3 of the bubble machine 10, at least a part of the bubble sending air duct body 30 is arranged side by side with the liquid storage 200.

[0124] In other alternative embodiments, the bubble sending fan 400 and the first pipe body 301 are arranged side by side in the length direction D2 or width direction D3 of the bubble machine 10.

[0125] In other alternative embodiments, the liquid storage 200 can be arranged above the film forming nozzle 500, so that the bubble liquid in the liquid storage 200 flows to the film forming nozzle 500 by gravity.

[0126] Please continue to refer to Figure 1 and Figure 2 and refer to Figures 12 to 14As shown, the driving device 700 in the embodiment of the present application can not only drive the brush film body 600 to move, but also drive the bubble liquid in the liquid storage 200 to be transported to the bubble channel 530 of the film forming nozzle 500. Thus, in the embodiment of the present application, one driving device 700 can be used to drive the brush film body 600 and drive the bubble liquid. Compared with the method of using two driving devices to separately drive the film forming nozzle 500 and the bubble liquid, the embodiment of the present application can save a set of driving devices.

[0127] Specifically, the bubble machine 10 includes at least one infusion tube 702, and the pipeline of the infusion tube 702 communicates with the liquid storage tank 210 of the liquid storage 200 and the bubble channel 530 of the film forming nozzle 500. The driving device 700 includes at least one roller 703. During the rotation of at least one roller 703, the roller 703 can squeeze the infusion tube 702 to drive the bubble liquid in the liquid storage 200 to be transported to the bubble channel 530 of the film forming nozzle 500.

[0128] Exemplarily, the outer surface of the roller 703 is generally smooth.

[0129] Exemplarily, the outer surface of any roller 703 is in contact with the outer surface of the infusion tube 702, and the roller 703 can squeeze the infusion tube 702 to deform, so as to change the pipeline shape of the infusion tube 702. It should be understood that the material used for the infusion tube 702 can at least deform under the extrusion of the roller 703. Exemplarily, the infusion tube 702 is made of a flexible material.

[0130] Exemplarily, the part of the outer surface of any roller 703 in contact with the outer surface of the infusion tube 702 is an arc structure, such as a circular arc structure.

[0131] Exemplarily, any roller 703 includes a first roller body 7031 and a second roller body 7032 connected to each other. Along the rotation direction D4 of the roller 703, the first roller body 7031 is connected to the peripheral surface of the second roller body 7032. Along the rotation direction D4 of the roller 703, the outer surfaces of the first roller body 7031 and the second roller body 7032 are both arc structures, and the outer surfaces of the first roller body 7031 and the second roller body 7032 are both in contact with the outer surface of the infusion tube 702.

[0132] Wherein, the size of the first roller body 7031 is smaller than the size of the second roller body 7032, and along the rotation direction D4 of the roller 703, the first roller body 7031 is located in front of the second roller body 7032.

[0133] Exemplarily, the fact that the size of the first roller body 7031 is smaller than the size of the second roller body 7032 includes but is not limited to:

[0134] The height of the first roller body 7031 is less than the height of the second roller body 7032; and / or

[0135] The diameter of the first roller body 7031 is less than the diameter of the second roller body 7032.

[0136] Exemplarily, the second roller body 7032 is provided with a hollow interior. In the embodiments of the present application, since the size of the second roller body 7032 is larger than that of the first roller body 7031, even if the second roller body 7032 has a hollow interior, the second roller body 7032 can still have sufficient strength. Thus, the weight of the second roller body 7032 can be reduced, which is beneficial for driving by the motor 701 of the driving device 700.

[0137] Exemplarily, the gears of the driving device 700 include a first gear 711 and a second gear 712. The motor 701 is configured to drive the first gear 711 and the second gear 712 to rotate. It should be understood that the motor 701 can directly or indirectly drive the first gear 711 and the second gear 712 to rotate. In an alternative embodiment of the present application, the motor 701 directly or indirectly drives the first gear 711 and the second gear 712 through a driving gear 713 on its output shaft 7011.

[0138] Exemplarily, the roller 703 is disposed on one side surface of the first gear 711. When there are multiple rollers 703, the multiple rollers 703 are disposed on the same side surface of the first gear 711 and are spaced apart.

[0139] Exemplarily, the second gear 712 is connected to the brush film body 600, and the second gear 712 can drive the brush film body 600 to rotate during the rotation process.

[0140] In an alternative embodiment of the present application, the driving device 700 further includes a fourth gear 714, a fifth gear 715, and a sixth gear 716. The driving gear 713 meshes with the fourth gear 714, the fourth gear 714 meshes with the first gear 711, the first gear 711 meshes with the fifth gear 715, the fifth gear 715 meshes with the sixth gear 716, and the sixth gear 716 meshes with the second gear 712. When the motor 701 is powered on, or in other words, when the motor 701 is in a working state, its output shaft 7011 is driven to rotate and drives the driving gear 713 to rotate together. 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 roller 703 provided on one side thereof is driven to rotate together, thereby squeezing the infusion tube 702 to drive the bubble liquid located in the liquid storage 200 to the film forming nozzle 500. In addition, in an embodiment of the present application, one side of the second gear 712 is connected to the transmission member 717. During the rotation of the second gear 712, the shaft body 7171 fixed on the transmission member 717 and the film brushing body 600 are driven to rotate together to achieve the purpose of film brushing.

[0141] Exemplarily, the driving device 700 includes at least three rollers 703. The at least three rollers 703 are equidistantly arranged along the rotation axis 704 of the first gear 711. A part of the infusion tube 702 is arranged around the rotation axis 704 and is in contact with all the rollers 703.

[0142] In other alternative embodiments, any one of the rollers has a cylindrical structure, a conical structure, or a frustum structure. As Figure 15 shown, in another alternative embodiment of the present application, the roller 703b has a cylindrical structure. Figure 15 The other structures shown, such as the first gear 711 and the rotation axis 704, are the same as Figure 14 the first gear 711 and the rotation axis 704 shown.

[0143] It should be noted that in practical applications, when the bubble liquid reaches the film-forming nozzle 500, the film-brushing body 600 can rotate to achieve the purpose of brushing the film, that is, forming a bubble film. When the bubble liquid does not reach the film-forming nozzle 500, the rotation of the film-brushing body 600 is an ineffective rotation, wasting electricity. Based on this, in the process of the motor 701 driving the roller 703 and the shaft body 7171 in the embodiment of the present application, the driving motor 701 first drives the roller 703 and then drives the shaft body 7171. It can be understood that the driving sequence of the motor 701 is: first driving the roller 703 to rotate and then driving the shaft body 7171. It can also be understood that: the motor 701 drives the roller 703 before driving the shaft body 7171. It can also be understood that: the shaft body 7171 is driven by the first gear 711 where the roller 703 is located, and there is at least one stage of gear between the first gear 711 and the shaft body 7171. It should be understood that the film-brushing body 600 is connected to the shaft body 7171, and the motor 701 drives the film-brushing body 600 after driving the roller 703, or drives the roller 703 before driving the film-brushing body 600.

[0144] In other alternative embodiments, the motor 701 can also drive the roller 703 and the shaft body 7171 respectively by different paths. For example, the motor 701 drives the roller 703 and the shaft body 7171 respectively by two sets of gear sets.

[0145] Please continue to refer to Figure 12 and Figure 13 , the motor 701 is installed on the mounting seat 705. The motor 701 further includes a motor body 7012 and a protruding portion 7013.

The motor body 7012 is installed in the first groove 7015, and the protruding portion 7013 is installed in the second groove 7052. There are at least two limits between the motor 701 and the mounting seat 705 in the embodiment of the present application, which increases the installation stability of the motor 701 and at the same time increases the stability of the motor 701 during operation, and can reduce the impact of the vibration generated during the operation of the motor 701 on the bubble machine 10 to a certain extent.

[0146] Exemplarily, the mounting seat 705 can be connected to the mounting plate 706.
