[0023] Please also refer to Figures 1 to 5 The present embodiment provides a bubble blowing toy movement, including a shell 1, in which a driving component 2 and a bubble blowing component 3 are arranged. The driving component 2 is drivingly connected to the bubble blowing component 3, so that when the driving component 2 is started, the bubble liquid can be transported to the bubble blowing component 3, so that the bubble blowing component 3 spreads the bubble liquid into a film and then blows out to form bubbles.

[0024] The shell 1 is used to install and fix the drive assembly 2 and the bubble blowing assembly 3. A cavity 11 is provided in the shell 1. A part of the drive assembly 2 is rotatably provided in the cavity 11. The outer wall of the cavity 11 is provided with an inlet 12 and an outlet 13 for the conduit to enter and exit.

The shell 1 is also provided with other conventional structures such as air holes and a wick fixing seat. Since the conventional structures have been disclosed in the prior art, they are not described in detail. In other embodiments, the shell 1 can also adopt other detachable methods to connect the first shell and the second shell, such as bolt connection.

[0025] The driving assembly 2 includes a motor 21 and a transmission group 23. In this embodiment, the motor 21 is a dual-shaft motor. One of the output shafts of the motor 21 is fixed to the fan blades of the bubble blowing assembly 3, and is used to control the bubble blowing assembly 3 to rotate and generate wind when the motor 21 is started.

In other embodiments, the motor 21 can also be a single-shaft motor, in which case the fan blades of the bubble blowing assembly 3 and the transmission group 23 are both fixed to the same output shaft of the motor 21.

[0026] The transmission group 23 includes an output gear 231, a liquid pumping gear 232 and a driving gear 233. The output gear 231 is fixed to the output shaft of the motor 21.

The transmission ratio of the second reduction gear system 23b is less than half of the transmission ratio of the first reduction gear system 23a, and is used to control the rotation speed of the liquid pumping gear 232 to adapt to the rotation speed of the bubble blowing component 3. With the above arrangement, when only one liquid pumping gear 232 is provided, the liquid pumping gear 232 can be used to control the conduit to supply liquid to multiple liquid outlets, and at the same time, the film forming member of the bubble blowing component 3 can be controlled to rotate in accordance with the liquid outlet speed, thereby maintaining the bubble liquid application efficiency at a high level. It should be noted that the above arrangement is also applicable to a bubble blowing toy movement having a single liquid outlet structure.

[0027] It can be understood that in the first reduction gear system 23a, the output gear 231 is a worm gear, which is used to cooperate with other gears so that the transmission group 23 can extend along one end of the motor 21 to the bubble blowing component 3, thereby making the distribution of the transmission group 23, the motor 21, and the bubble blowing component 3 more compact, so as to achieve the purpose of reducing the shell 1. Two squeezing columns 2321 are provided on one side of the liquid pumping gear 232 away from the axis, and a conduit is provided between the squeezing columns 2321 and the inner wall of the cavity 11, and the conduit is used to transport bubble liquid to the air guide of the bubble blowing component 3 under the squeezing of the squeezing columns 2321.

[0028] In this embodiment, the first gear set 234 includes a first gear 2341, and the first gear 2341 and the liquid pumping gear 232 are spur gears with different diameters, and the diameter of the first gear 2341 is smaller than the diameter of the liquid pumping gear 232. Among them, the gear ratio between the first gear 2341 and the output gear 231 is 4:1, and the gear ratio between the first gear 2341 and the liquid pumping gear 232 is 2:5. At this time, the transmission ratio of the first reduction gear system 23a is 10. According to the gear ratio setting between the above-mentioned meshing gears, in this embodiment, the number of teeth of the output gear 231 is set to 5, the number of teeth of the first gear 2341 is set to 20, and the number of teeth of the liquid pumping gear 232 is set to 50. In other embodiments, the first gear set 234 may also include more than two meshing gears. At this time, the gear ratio setting between the meshing gears in the first reduction gear system 23a can be adjusted according to the number of liquid outlets. At this time, the transmission ratio of the first reduction gear system 23a can be other values.

[0029] In this embodiment, the second gear set 235 includes a second gear 2351, a third gear 2352 and a fourth gear 2353 that mesh in sequence, the second gear 2351 meshes with the pumping gear 232, and the fourth gear 2353 meshes with the driving gear 233. The second gear 2351, the fourth gear 2353 and the driving gear 233 are double gears, the large gear of the driving gear 233 is a crown gear, and the third gear 2352 is a spur gear.

[0030] In the second reduction gear system 23b, the second gear 2351 includes two coaxial large and small gears with a gear ratio of 2:1, the gear ratio between the large gear of the second gear 2351 and the liquid pumping gear 232 is 2:5, and the gear ratio between the small gear of the second gear 2351 and the third gear 2352 is 1:2. The fourth gear 2353 includes two coaxial large and small gears with a gear ratio of 7:4, the driving gear 233 includes two coaxial large and small gears with a gear ratio of 20:9, the gear ratio between the small gear of the fourth gear 2353 and the third gear 2352 is 2:5, the gear ratio between the large gear of the fourth gear 2353 and the large gear of the driving gear 233 is 7:10, and the gear ratio between the small gear of the driving gear 233 and the gear ring in the bubble blowing component 3 is 9:92. At this time, the transmission ratio of the second reduction gear system 23b is 4.67, which is slightly less than half of the transmission ratio of the first reduction gear system 23a.

[0031] According to the tooth ratio setting between the above-mentioned meshing gears, in this embodiment, the number of teeth of the large and small gears of the second gear 2351 is set to 20 and 10, the number of teeth of the third gear 2352 is set to 20, the number of teeth of the large and small gears of the fourth gear 2353 is set to 14 and 8, the number of teeth of the large and small gears of the driving gear 233 is set to 20 and 9, and the number of teeth of the ring gear in the bubble blowing component 3 is set to 92.

[0032] In other embodiments, the second gear set 235 may also include one, two or more than four meshing gears. In this case, the gear ratio setting between the meshing gears in the second reduction gear system 23b can be adaptively adjusted according to the transmission ratio value of the first reduction gear system 23a.

[0033] The bubble blowing component 3 includes a film forming member 31, an air guide member 32 and a fan blade 33, wherein the film forming member 31 can be rotatably arranged on the shell 1, the air guide member 32 is fixed in the shell 1 and is located between the film forming member 31 and the fan blade 33, the air guide member 32 is rotationally connected to the film forming member 31, and the fan blade 33 is fixed to the output shaft of the motor 21.

[0034] The film forming member 31 includes a central axis 311, a gear ring 312 located on the outer wall of the film forming member 31, and a plurality of film forming rings 313 distributed in a concentric circle structure with the central axis 311 as the center. The central axis 311 is rotatably connected with the air guide member 32 to improve the stability of the rotation of the film forming member 31. The gear ring 312 is meshed with the pinion of the driving gear 233 to enable the film forming member 31 to rotate under the driving control of the transmission group 23. Each film forming ring 313 can collide with the liquid outlet of the air guide member 32 during the rotation process, so as to apply the bubble liquid to form a film during the rotation process.

[0035] In this embodiment, the air guide member 32 includes a central groove 321, a plurality of air guide plates 322 with the central groove 321 as the center and distributed in a radial structure, and two liquid outlet platforms 323 spaced apart from the air guide plates 322. Among them, a central axis 311 is rotatably connected in the central groove 321. The air guide plates 322 are arranged opposite to the air outlet direction of the fan blades 33, and are used to guide the airflow generated by the fan blades 33 to the film forming member 31. The two liquid outlet platforms 323 are relatively arranged on the same straight line, and each liquid outlet platform 323 is provided with two liquid outlets 3231 in the straight line direction. The liquid outlet platform 323 is connected to the liquid storage tank through the conduit, and is used to transport bubble liquid to the film forming ring 313 through the liquid outlet 3231.

[0036] The working principle of the bubble blowing toy movement provided in this embodiment is as follows: when the motor 21 is started, it will drive the fan blades 33 and the transmission group 23 to rotate at the same time. At this time, the first reduction gear system 23a drives the liquid pumping gear 232 to rotate at a certain speed, so as to squeeze the conduit to simultaneously deliver bubble liquid to the two liquid outlets 323. Since the transmission ratio of the second reduction gear system 23b is less than half of the transmission ratio of the first reduction gear system 23a, the second reduction gear system 23b drives the gear ring 312 to rotate at a speed that is several times slower than the speed of the liquid pumping gear 232, so that the film forming member 31 can rotate in accordance with the liquid outlet speed of the liquid outlet 3231, so as to maintain a high efficiency of the bubble liquid coating and film forming, so that the bubble blowing toy movement can continuously blow out a large number of bubbles.

[0037] Since the ratio of the rotational speed of the pumping gear 233 to the rotational speed of the ring gear 312 is equal to the transmission ratio of the second reduction gear system 23b, the ratio of the rotational speed of the output shaft of the motor 21 to the rotational speed of the pumping gear 233 is equal to the transmission ratio of the first reduction gear system 23a, and the transmission ratio of the second reduction gear system 23b is less than half of the transmission ratio of the first reduction gear system 23a, it can be known that the rotational speed of the pumping gear 233 is a multiple of the rotational speed of the ring gear 312.
