[0058] In order to make the objective, technical solution and advantages of the present invention clearer, the technical solution in embodiments will be clearly and completely described below with reference to the accompanying drawings in embodiments of the present invention. The following embodiments are intended to illustrate the present invention rather than limit the scope of the present invention.

[0059] In the description of the present invention, it should be noted that directions or positional relations indicated by terms, such as upper, lower, internal, external, and the like, are directions or positional relations shown in the accompanying drawings, which are merely intended to conveniently describe the present invention and simplify description rather than indicate or imply that the indicated device or components must have specific directions and be structured and operated according to the specific directions, and therefore should not be interpreted as limitations on the present invention.

[0060] In the description of the present disclosure, it should be noted that unless clearly specified and defined otherwise, terms, such as mounting and connection, should be broadly comprehended as a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, a direct connection or an indirect connection through an intermediate. For those of ordinary skill in the art, specific meanings of the above terms in the present invention can be understood according to specific conditions.

[0061] Refer to FIG. 1 to FIG. 8. An embodiment of the present application provides a bubble blowing device, including a shell 1, an air guide disc 2, a drive gear train, a bubble solution bottle, and at least two solution-feeding tubes 3. The air guide disc 2 is arranged in the shell 1. At least two solution supply nozzles are arranged on the air guide disc 2, and the solution-feeding tubes 3 are connected to the corresponding solution supply nozzles respectively. The drive gear train is arranged in the shell 1, and is configured to drive the solution-feeding tubes 3 to feed solution respectively. The bubble solution bottle is connected to the shell 1, and an end of each solution-feeding tube 3 extends into the bubble solution bottle. The drive gear train can drive the solution-feeding tubes 3, so that the solution-feeding tubes can suck bubble solution in the bubble solution bottle and feed it into the solution supply nozzles.

[0062] According to the bubble blowing device provided in the present application, the at least two solution-feeding tubes 3 are arranged and each solution-feeding tube 3 directly extends into the bubble solution bottle, to form at least two independent solution supply paths, so that more solution can be fed and more bubbles can be produced, making the bubble blowing device more interesting and bringing good experience to players.

[0063] In some possible embodiments, the drive gear train includes at least two solution-feeding squeeze gears 4, the solution-feeding tubes 3 pass through the corresponding solution-feeding squeeze gears 4 in a surrounding manner respectively, and the solution-feeding squeeze gears 4 can rotate to squeeze the corresponding solution-feeding tubes 3 to feed the solution.

[0064] The bubble blowing device includes a motor 5, which is in a transmissive connection with the drive gear train. When the motor 5 rotates, the drive gear train can be driven to drive the two solution-feeding squeeze gears 4 therein to rotate and squeeze the solution-feeding tubes 3, so that the solution in the solution-feeding tubes 3 flows towards the solution supply nozzle, to be jetted out. The solution-feeding squeeze gears 4 can keep rotating to repeatedly squeeze the solution-feeding tubes 3, so that the bubble solution in the bubble solution bottle can be continuously sucked by the solution-feeding tubes 3.

[0065] In some possible embodiments, as shown in FIG. 2 and FIG. 3, the shell 1 is provided with at least two accommodating grooves, each solution-feeding squeeze gear 4 is provided with an eccentric shaft 41, at least the eccentric shaft 41 is located in the accommodating groove, the solution-feeding tubes 3 extend through the corresponding accommodating grooves respectively, and the solution-feeding tubes 3 pass through the corresponding eccentric shafts 41 in a surrounding manner respectively. The solution-feeding squeeze gears 4 can rotate to drive the eccentric shafts 41 to squeeze the solution-feeding tubes 3, thus realizing solution feeding by driving. It should be noted that working principles of the solution-feeding squeeze gears 4 and the solution-feeding tubes 3 are the mature prior art, and do not pertain to the inventive points of the present application as well, so the present application does not limit them.

[0066] In some possible embodiments, the bubble blowing device includes the motor 5, the drive gear train includes at least two side gear trains, and the motor 5 and each side gear train are both arranged in the shell 1. Each side gear train is provided with a plurality of gears, the gears are arranged in sequence, adjacent gears are meshed, and one of the gears is the solution-feeding squeeze gear 4. The motor 5 is connected with a worm 51, and a gear at an input end of each side gear train is meshed with the worm 51.

[0067] In the present application, the motor 5 needs to drive two sets of drive gear trains to operate at the same time, and adopts a gear-worm 51 transmission fit mode to reduce power output of the motor 5. Compared with pure gear transmission, the transmission of the worm 51 has a greater reduction ratio and can also achieve a greater output torque. Consequently, usage of gears can be reduced, noise generated in a transmission process can be reduced, and durability is better than that of full gear reduction as well.

[0068] In some possible embodiments, the bubble blowing device includes a rotatable bubble disc 6 and a transmission rod 7. The rotatable bubble disc 6 is rotatably connected to the shell 1, and a toothed ring is arranged on the rotatable bubble disc 6. Both ends of the transmission rod 7 are connected with a first gear 71 and a second gear 72 respectively, the first gear 71 is meshed with a gear of one of the side gear trains, and the second gear 72 is meshed with the toothed ring. The operation of the drive gear train can drive the transmission rod 7 to rotate, so that the transmission rod 7 can drive the rotatable bubble disc 6 to rotate.

[0069] In some possible embodiments, the bubble blowing device includes a fan blade 8, and the shell 1 includes a cylindrical shell 11 and a power shell 12, which are arranged in sequence. The air guide disc 2 and the rotatable bubble disc 6 are both arranged in the cylindrical shell 11, and the power shell 12 is connected to a side that is of the cylindrical shell 11 and that is away from the rotatable bubble disc 6. The motor 5 and the drive gear train are both arranged in the power shell 12. The fan blade 8 is located in the cylindrical shell 11, and is in a transmissive connection with the motor 5. A rotary shaft of the motor 5 penetrates through the shell 1 of the motor 5, and both ends of the rotary shaft are connected with the worm 51 and the fan blade 8 respectively.

[0070] In some possible embodiments, as shown in FIG. 1, the power shell 12 is connected to an opening edge of the cylindrical shell 11 through a plurality of connecting ribs 13, and a hollow portion communicating with an internal cavity of the cylindrical shell 11 is formed between adjacent connecting ribs 13. During high-speed rotation of the fan blade 8, outside air can enter the cylindrical shell 11 via the hollow portion and ultimately be exhausted by the rotatable bubble disc 6. The hollow portion is arranged to make an air path unobstructed.

[0071] In some possible embodiments, as shown in FIG. 5, the rotatable bubble disc 6 is provided with a plurality of bubble solution-applying components. Each bubble solution-applying component includes a plurality of bubble solution-applying rings 61 which are arranged in a circumferential direction of the rotatable bubble disc 6 in sequence, and the bubble solution-applying rings 61 are located on a same circular track. The bubble solution-applying components are arranged in a radial direction of the rotatable bubble disc 6 in sequence. During rotation of the rotatable bubble disc 6, each circle of bubble solution-applying rings 61 on the rotatable bubble disc 6 are in contact with the corresponding solution supply nozzle respectively. In embodiments of the present application, there are a large number of solution-feeding tubes 3, so a plurality of circles of bubble solution-applying rings 61 may be arranged correspondingly, thus increasing a number of produced bubbles.

[0072] In some possible embodiments, lengths of all the solution supply nozzles are different, the solution supply nozzles are arranged at intervals in the circumferential direction of the rotatable bubble disc 6 in sequence, and each solution supply nozzle extends from a bubble solution-applying component on an outermost circle to a side of a circle center of the rotatable bubble disc 6. Since the number of the outer circle of bubble solution-applying rings 61 is larger than the number of the inner circle of bubble solution-applying rings 61, in the present application, through the specific setting of the length of each solution supply nozzle, the number of the solution supply nozzles for applying the bubble solution onto the corresponding outer circle of bubble solution-applying rings 61 is also larger, so that the fed solution amounts and solution feeding frequencies of the outer circle of bubble solution-applying rings and the inner circle of bubble solution-applying rings are relatively balanced.

[0073] In some possible embodiments, as shown in FIG. 5 and FIG. 6, the rotatable bubble disc 6 is provided with three bubble solution-applying components, which form three circles of bubble solution-applying rings from inside to outside. Each of the solution supply nozzles includes any two or all of a first solution supply nozzle 21, a second solution supply nozzle 22, and a third solution supply nozzle 23. The first solution supply nozzle 21 only extends through the inside of the outermost bubble solution-applying component, and can apply the solution onto the outermost circle of bubble solution-applying rings. The second solution supply nozzle 22 only extends through the inside of the outermost bubble solution-applying component and the inside of the middle bubble solution-applying component, and the first solution supply nozzle 21 can apply the solution onto the outermost circle of bubble solution-applying rings and the middle circle of bubble solution-applying rings. The third solution supply nozzle 23 extends through the outermost bubble solution-applying component, the middle bubble solution-applying component, and the innermost bubble solution-applying component. The third solution supply nozzle 23 can apply the solution onto the outermost circle of bubble solution-applying rings, the middle circle of bubble solution-applying rings, and the innermost circle of bubble solution-applying rings.

[0074] Optionally, as shown in FIG. 6 to FIG. 8, the solution supply nozzle includes a main body 201 and a cover 202. The main body 201 is connected to the air guide disc 2. The main body 201 is provided with a solution reservoir 2011 and a connecting nozzle 2012 communicating with the solution reservoir 2011, and the solution reservoir 2011 and the connecting nozzle 2012 are located at two sides of the air guide disc 2 in a thickness direction respectively. The solution-feeding tube 3 is connected to the connecting nozzle 2012. The cover 202 is connected to the main body 201, and covers the solution reservoir 2011. The cover 202 is provided with a through hole 2021 communicating with the solution reservoir 2011, and an annular groove 2022 is provided around an edge of an outer surface of the cover 202. The rotatable bubble disc 6 is in contact with or close to the cover 202. The solution in the solution-feeding tube 3 can be injected into the connecting nozzle 2012 and then flow into the solution reservoir 2011 from the connecting nozzle 2011. The bubble solution in the solution reservoir 2011 flows out of the through hole 2021 and enters the annular groove 2022, so that the bubble solution can be applied onto the bubble solution-applying ring when the bubble solution-applying ring is in contact with the cover 202.

[0075] In some possible embodiments, an edge of a side that is of the main body 201 and that is away from the cover 202 is provided with a flange 2013, and portions that are of the flange 2013 and that are located at both sides of the connecting nozzle 2012 are provided with notches 2014. The notches 2014 are arranged to avoid the connecting nozzles 2012, so that ends of the solution-feeding tubes 3 can be conveniently sleeved onto the connecting nozzles 2012 by manual or equipment operation.
