[0037] Figure 1 and Figure 2 FIG. 1 shows a bubble blowing device 10 in some embodiments of the present invention, which can generate bubbles. Figures 1 to 5 As shown, the bubble blowing device 10 includes a bracket 1, a motor 2, a bubble blowing device 3, a speed reducing device 4 and a liquid pumping device 5, and the motor 2, the bubble blowing device 3, the speed reducing device 4 and the liquid pumping device 5 are respectively arranged on the bracket 1.

[0038] As can be understood, the bracket 1 serves to support and fix the device. The motor 2 is used to output torque. The bubble blowing device 3 is used to generate bubbles. The reduction gear 4 is used to further transmit the torque of the motor 2 to the bubble blowing device 3. The pumping device 5 is used to pump liquid, such as the bubble liquid used to generate bubbles.

[0039] like Figures 1 to 5 As shown, the motor 2 is mounted on the bracket 1 and has an output shaft 21. The bubble blowing device 3 includes a fan blade 31 and a bubble net 32. The fan blade 31 is driven and connected to the output shaft 21, and the bubble net 32 ​​is movably mounted on the bracket 1. The pumping device 5 is used to pump liquid to the bubble net 32. The reduction gear 4 is disposed along the longitudinal extension direction D1 of the output shaft 21 and is located between the fan blade 31 and the bubble net 32. One end of the reduction gear 4 is driven and connected to the output shaft 21, and the other end of the reduction gear 4 is driven and connected to the bubble net 32. The motor 2 drives the output shaft 21 to rotate, which in turn drives the fan blade 31 to rotate, and drives the bubble net 32 ​​to rotate via the reduction gear 4.

[0040] It is understood that the bracket 1 is used to fix and install other components, ensuring the stability and structural integrity of the entire device. The motor 2 outputs torque through the output shaft 21. When the motor 2 is working, the output shaft 21 will rotate.

[0041] The fan blades 31 are directly connected to the output shaft 21 of the motor 2 and rotate with the rotation of the output shaft 21 to generate airflow; the bubble net 32 ​​is movably set on the bracket 1 and is indirectly connected to the output shaft 21 through the reduction device 4.

[0042] The speed reducer 4 is located along the lengthwise extension D1 of the output shaft 21, between the fan blades 31 and the bubble net 32. One end of the speed reducer is connected to the output shaft 21, and the other end is connected to the bubble net 32. The speed reducer 4 primarily regulates the rotational speed transmitted from the output shaft 21, ensuring that the bubble net 32 ​​operates at a stable speed.

[0043] It should be noted that when the motor 2 is started, the output shaft 21 begins to rotate. The fan blades 31 rotate accordingly, generating airflow. Simultaneously, the reduction gear 4 converts the high rotational speed of the output shaft 21 into a low rotational speed suitable for the operation of the bubble net 32. This has the following advantages: on the one hand, the reduction gear 4 can reduce the vibration of the bubble net 32 ​​caused by the high-speed rotation, thereby enhancing the stability of the bubble blowing device 10 during operation; on the other hand, the speed regulation of the reduction gear 4 allows the bubble net 32 ​​to rotate at a more uniform speed, which is conducive to the formation of more stable and continuous bubbles.

[0044] Furthermore, by positioning the reduction gear 4 along the lengthwise extension direction D1 of the output shaft 21, the entire bubble blowing device 10 is made more compact, making it easier to carry and store. This is particularly important for children's toys, as the smaller size not only makes it easier for children to operate but also provides greater convenience for families. Specifically, by positioning the reduction gear 4 along the lengthwise extension direction D1 of the output shaft 21, the output shaft 21 can be connected to the bubble net via the reduction gear over a shorter distance, eliminating the need for an oversized ring gear around the periphery of the bubble net for torque transmission. This also eliminates the need for a long rod with a gear, eliminating the need to reserve more space around the periphery of the bubble net for torque transmission components. This results in a smaller overall volume for the bubble blowing device 10, improving overall compactness.

[0045] like Figures 3 to 5 As shown, in some embodiments of the bubble blowing device 10, the deceleration device 4 includes an eccentric wheel 411, a driving ring gear 412 and a driven ring gear 413, and the eccentric wheel 411, the driving ring gear 412 and the driven ring gear 413 are all located in the length extension direction D1 of the output shaft 21; the eccentric wheel 411 is driven and connected to the output shaft 21, the driving ring gear 412 is arranged on the eccentric wheel 411, and the driven ring gear 413 is arranged on the bubble net 32, the driving ring gear 412 is located in the driven ring gear 413, and the driving ring gear 412 is engaged with the driven ring gear 413; the output shaft 21 drives the eccentric wheel 411 to rotate, and the eccentric wheel 411 drives the driving ring gear 412 to rotate, so that the driving ring gear 412 drives the bubble net 32 ​​to rotate through the driven ring gear 413.

[0046] It can be understood that the eccentric wheel 411 is directly driven and connected to the output shaft 21. When the motor 2 is started, the output shaft 21 rotates, driving the eccentric wheel 411 to rotate synchronously. The driving ring gear 412 is set on the eccentric wheel 411. As the eccentric wheel 411 rotates, the driving ring gear 412 also rotates. The driven ring gear 413 is set on the bubble net 32 ​​and is located outside the driving ring gear 412. The driving ring gear 412 is engaged with the driven ring gear 413, which means that when the driving ring gear 412 rotates, it will drive the bubble net 32 ​​to rotate through the meshing action with the driven ring gear 413.

[0047] It should be noted that when the motor 2 is started, the output shaft 21 begins to rotate, driving the eccentric 411. The rotation of the eccentric 411 in turn drives the connected drive ring gear 412. Because the drive ring gear 412 meshes with the driven ring gear 413, the rotation of the drive ring gear 412 is transmitted to the bubble net 32 ​​through the driven ring gear 413, thereby driving the bubble net 32 ​​to rotate.

[0048] It should also be noted that the number of teeth on the driving ring gear 412 is less than the number of teeth on the driven ring gear 413 . Thus, when the bubble net is driven by the driving ring gear 412 and the driven ring gear 413 , speed reduction can be achieved.

[0049] like Figure 3 and Figure 4 As shown, in some embodiments of the bubble blowing device 10 , a limiting portion 414 is provided on the driving gear ring 412 , a limiting hole 11 is provided on the bracket 1 , the limiting portion 414 is movably inserted into the limiting hole 11 , and the limiting hole 11 is used to limit the limiting portion 414 .

[0050] As can be understood, the stopper 414 is movably inserted into the stopper hole 11 on the bracket 1, thereby limiting the radial displacement of the drive ring gear 412 during rotation, preventing it from swinging unnecessarily or deviating from its predetermined trajectory. This not only helps to reduce vibration that may occur during rotation of the bubble net 32, but also improves the reliability and durability of the entire transmission system.

[0051] It should be noted that when the eccentric rotates, the driving ring gear 412 will always remain in meshing with the driven ring gear 413. During the rotation of the driving ring gear 412, the limiting portion 414 will always remain at least partially inserted into the limiting hole 11, and the limiting portion 414 will move to a certain extent under the drive ring gear 412.

[0052] In other embodiments, the limiting hole 11 can be configured to be opened on the liquid distribution plate 52. In this way, the position of the limiting portion 414 can also be limited by a structure that does not change position relative to the bracket 1.

[0053] like Figures 3 to 5 As shown, in some embodiments of the bubble blowing device 10, the reduction gear 4 includes a sun gear 421, a planetary gear 422, a bracket 423 and a fixed ring gear 424, the sun gear 421 is sleeved on the output shaft 21, the planetary gear 422 is rotatably set on the bracket 423, the bracket 423 is driven and connected to the bubble net 32, the fixed ring gear 424 is set on the bracket 1, and the planetary gears 422 are respectively engaged with the sun gear 421 and the fixed ring gear 424.

[0054] It can be understood that the output shaft 21 drives the sun gear 421 to rotate, the sun gear 421 drives the planetary gears 422 to rotate, and the planetary gears 422 drive the bracket 423 to rotate, and then the bracket 423 drives the bubble net 32 ​​to rotate.

[0055] The sun gear 421 is mounted on the output shaft 21 and rotates with the output shaft 21. The planetary gear 422 is mounted on the bracket 423 and can rotate freely around its own axis. The planetary gear 422 is engaged with the sun gear 421 and the fixed ring gear 424 at the same time. The bracket 423 is used to support the planetary gear 422 and is driven to be connected to the bubble net 32. When the planetary gear 422 rotates, the bracket 423 will also rotate, thereby driving the bubble net 32 ​​to rotate. The fixed ring gear 424 is set on the bracket 1 and engages with the planetary gear 422, but does not participate in the active rotation.

[0056] It should be noted that when the motor 2 is started, the output shaft 21 begins to rotate, driving the sun gear 421. The rotation of the sun gear 421 causes the meshing planetary gears 422 to rotate about their own axes. Because the planetary gears 422 are also meshed with the fixed ring gear 424, the rotation of the planetary gears 422 forces the bracket 423 to rotate along the circumference of the fixed ring gear 424. The bracket 423 ultimately drives the bubble net 32 ​​to rotate, allowing the bubble liquid used to generate bubbles to adhere evenly to the bubble net, ensuring stable and uniform bubble formation.

[0057] It should also be noted that, through the content of this embodiment, the product can achieve a high reduction ratio in a smaller size, making the bubble blowing device 10 more compact and easier to carry and use. Due to the dual meshing of the planetary gear 422 with the sun gear 421 and the fixed ring gear 424, the entire transmission system is more stable, reducing the shaking of the bubble net 32 ​​during rotation.

[0058] like Figures 3 to 5 As shown, in some embodiments of the bubble blowing device 10 , the sun gear 421 is disposed on the fan blade 31 .

[0059] As can be understood, the sun gear 421 is directly mounted on the fan blades 31. When the motor 2 is started, the output shaft 21 drives the fan blades 31 to rotate, which in turn drives the sun gear 421 to rotate synchronously. The rotation of the sun gear 421 is transmitted to the bubble net 32 ​​through the reduction gear 4, thereby driving the bubble net 32 ​​to rotate.

[0060] It should be noted that mounting the sun gear 421 directly on the fan blades 31 eliminates intermediate transmission links, making the entire torque transmission chain simpler and reducing the possibility of failure. Furthermore, the integrated design of the sun gear 421 and the fan blades 31 reduces vibration problems caused by excessive intermediate transmission links during rotation, making the rotation of the bubble net 32 ​​smoother and improving the stability and quality of bubble production.

[0061] like Figure 3 and Figure 4As shown, in some embodiments of the bubble blowing device 10 , the reduction gear 4 includes three planetary gears 422 , each planetary gear 422 is rotatably disposed on a bracket 423 , the sun gear 421 is meshed with each planetary gear 422 , and each planetary gear 422 is meshed with a fixed ring gear 424 .

[0062] It can be understood that configuring the number of planetary gears 422 to be three allows the product to transmit torque through multi-point contact, so that the load borne by each gear is relatively uniform, thereby extending the service life of the entire transmission system.

[0063] like Figure 3 and Figure 5 As shown, in some embodiments of the bubble blowing device 10 , at least one plug shaft 425 is provided on the bracket 423 , and each plug shaft 425 is provided with a planetary gear 422 .

[0064] It is understandable that the number of the insertion shafts 425 is configured to be equal to the number of the planetary gears 422. The insertion shafts 425 are used to support the planetary gears 422 for rotation. On the other hand, the planetary gears 422 can also drive the bracket 423 to rotate through the insertion shafts 425.

[0065] like Figures 3 to 5 As shown, in some embodiments of the bubble blowing device 10, the reduction gear 4 includes a sun gear 421, a planetary gear 422, a bracket 423 and a fixed ring gear 424, the sun gear 421 is sleeved on the output shaft 21, the planetary gear 422 is rotatably set on the bracket 423, the bracket 423 is driven and connected to the bubble net 32, the fixed ring gear 424 is set on the bracket 1, and the planetary gears 422 are respectively engaged with the sun gear 421 and the fixed ring gear 424; the output shaft 21 drives the sun gear 421 to rotate, the sun gear 421 drives the planetary gear 422 to rotate, so that the planetary gear 422 drives the bracket 423 to rotate, and then the bracket 423 drives the bubble net 32 ​​to rotate.

[0066] In addition, in this embodiment, the reduction gear 4 further includes an eccentric wheel 411, a driving ring gear 412, and a driven ring gear 413. The eccentric wheel 411, the driving ring gear 412, and the driven ring gear 413 are all located in the length extension direction D1 of the output shaft 21.

[0067] The eccentric wheel 411 is disposed on the bracket 423 , the driving ring gear 412 is disposed on the eccentric wheel 411 , and the driven ring gear 413 is disposed on the bubble net 32 ​​. The driving ring gear 412 is located inside the driven ring gear 413 and meshes with the driven ring gear 413 .

[0068] When the bracket 423 drives the eccentric wheel 411 to rotate, the eccentric wheel 411 drives the driving ring gear 412 to rotate, so that the driving ring gear 412 drives the bubble net 32 ​​to rotate through the driven ring gear 413.

[0069] As will be understood, when motor 2 is started, the torque shaft 22 and output shaft 21 of the dual-shaft motor begin to rotate. The torque shaft 22 drives the liquid pump 51, which pumps liquid from the liquid storage container to the liquid distribution plate 52. The liquid is evenly distributed onto the bubble net 32 ​​through the liquid guide holes 53 in the liquid distribution plate 52. The drive ring gear 412 meshes with the driven ring gear 413.

[0070] At the same time, the output shaft 21 rotates the fan blades 31, which in turn rotates the sun gear 421. The sun gear 421 meshes with the planetary gears 422, transmitting rotational force to the planetary gears 422. The planetary gears 422 then rotate the bracket 423 via the fixed ring gear 424. The bracket 423 rotates the eccentric 411, which in turn rotates the driving ring gear 412. The driving ring gear 412, in turn, rotates the bubble net 32 ​​via the driven ring gear 413.

[0071] This embodiment utilizes a planetary gear reduction mechanism and an eccentric gear reduction mechanism to achieve multiple decelerations of the bubble net's rotation, significantly reducing potential vibrations during rotation and ensuring more stable bubble generation. Specifically, the coordination of the sun gear 421, planetary gears 422, and fixed ring gear 424, combined with further deceleration by the eccentric gear 411, driving ring gear 412, and driven ring gear 413, results in smoother rotation of the bubble net 32 ​​and reduced shaking.

[0072] like Figures 3 to 5 As shown, in some embodiments of the bubble blowing device 10, the deceleration device 4 also includes a connecting seat 43, which is plugged into the bubble net 32. The connecting seat 43 is provided with a avoidance groove 431 on the surface away from the bubble net 32, and the driven gear ring 413 is integrally formed in the avoidance groove 431.

[0073] It is understandable that the connection between the connection base 43 and the bubble net 32 ​​allows the product to be quickly disassembled in a short time, improving the maintenance convenience of the product. At the same time, users can also replace different bubble nets according to different usage needs.

[0074] The relief groove 431 accommodates and limits the driven ring gear 413 and the driving ring gear 412, ensuring that they maintain stable and reliable meshing within the groove space. The driven ring gear 413 is integrally formed and disposed within the relief groove 431, allowing the driven ring gear 413 to be tightly coupled to the connecting seat 43, thereby enhancing the structural strength and stability of the entire reduction gear 4.

[0075] like Figures 3 to 5As shown, in some embodiments of the bubble blowing device 10, the liquid pump device 5 includes a liquid pump 51 and a liquid distribution plate 52. The liquid pump 51 is disposed on the bracket 1, and the liquid distribution plate 52 is disposed between the fan blades 31 and the bubble net 32. The liquid distribution plate 52 is provided with a liquid guide hole 53, and the liquid pump 51 is connected to the liquid distribution plate 52. The fixed gear ring 424 is disposed on the liquid distribution plate 52;

[0076] At least one clamping portion 54 is provided on the liquid distribution plate 52 , and at least one clamping hole 12 is opened on the bracket 1 . Each clamping portion 54 is clamped to each clamping hole 12 in a one-to-one correspondence.

[0077] As can be understood, the entirety of the pumping device 5 is conventional technology, and can be configured to deform the hose through a cyclically moving support member, thereby enabling liquid to be transported along the hose through the deformation. The provision of the clamping portion 54 allows the liquid distribution plate 52 to be quickly and securely mounted on the bracket 1, improving the production and assembly efficiency of the product.

[0078] It should be noted that the liquid can be guided through the tube. A connector can be provided on the liquid distribution plate 52 to guide the bubble liquid into the liquid distribution plate 52 through the connector. The number of the clamping portions 54 can be set to multiple, and the number of the clamping holes 12 can be configured to multiple, with each clamping portion 54 corresponding to each clamping hole 12 and clamping it.

[0079] like Figures 3 to 5 As shown, in some embodiments of the bubble blowing device 10, the motor 2 is a dual-axis motor, which has a torque shaft 22 and an output shaft 21, and the dual-axis motor is arranged on the bracket 1; the liquid pump 51 is driven and connected to the torque shaft 22, and the liquid pump 51 is driven by the torque shaft 22 to pump the liquid to the liquid distribution plate 52, and the liquid flows to the bubble net 32 ​​through the liquid guide hole 53.

[0080] As can be understood, the liquid pump 51 is driven by the torque shaft 22 to pump liquid to the liquid distribution plate 52, and the liquid (bubble liquid for forming bubbles) then flows through the liquid guide hole 53 to the bubble net 32. The bubble liquid can form a bubble film on the bubble net 32, and the gas flow causes the bubble film to deform to form bubbles.

[0081] The implementation of this utility model has the following beneficial effects:

[0082] The utility model relates to a bubble blowing device that effectively solves the problem of vibration of the bubble net during rotation by providing a reduction gear connecting the output shaft of a motor and the bubble net. Specifically, the reduction gear can slow down and stabilize the rotation speed of the bubble net when the output shaft rotates at high speed, thereby reducing vibration of the bubble net during operation and improving the smoothness and reliability of the bubble blowing device.

[0083] Furthermore, by arranging the deceleration device in the extension direction of the output shaft length, the torque transmission distance between the output shaft and the bubble net can be effectively shortened. On the one hand, this can avoid the problem of excessive vibration caused by the long torque transmission distance, further improving the operational smoothness and reliability of the product; on the other hand, it can also make the structure of the entire bubble blowing device more compact, which is not only easy to carry, but also saves storage space.

[0084] The scheme of the present invention has been described in detail above with reference to the accompanying drawings. In the above embodiments, the descriptions of each embodiment have their own emphases. For parts that are not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments. Those skilled in the art should also be aware that the actions and modules involved in the description are not necessarily required for the present invention. In addition, it can be understood that the steps in the method of the embodiment of the present invention can be adjusted in sequence, merged and deleted according to actual needs, and the modules in the device of the embodiment of the present invention can be merged, divided and deleted according to actual needs.
