The bubble outlet 2 includes a bubble forming frame 21 and an air guide frame 22. The air guide frame 22 is close to one side of the power compartment 4, and an axial hole 222 is provided at the center of the air guide frame 22.

[0032] Among them, the outer cover shell 1 is formed by snap-fitting between the shell 1 11 and the shell 2 12. The wind blown out from one side of the air guide frame 22 is used to blow out the bubble liquid transported to the bubble forming frame 21 through the infusion tube 3 to form abundant bubbles. Moreover, under the driving action of the power compartment 4, the bubble forming frame 21 rotates accordingly, while preventing the bubble liquid from accumulating at the liquid outlet 223 and continuously and evenly transporting it to the bubble forming frame 21.

[0033] Example 2

[0034] Based on Example 1, the solution in Example 1 is further detailed in combination with the following specific working methods. Figures 1 to 10 As shown, see the following description for details:

[0035] As a preferred embodiment, the inner wall of the bubble forming frame 21 facing the air guide frame 22 is provided with a circle of inner edge gear ring 212, and the inner edge gear ring 212 is meshed with a drive shaft 43, and the drive shaft 43 includes a reversing tooth 431 and a main wheel 432, and the outermost side of the bubble forming frame 21 is connected to a ring-shaped liquid collecting ring 211 by using several support columns 213; further, the bubble forming frame 21 is used to rotate at a uniform speed relative to the air guide frame 22 by using the inner edge gear ring 212, so that the ring-shaped liquid collecting ring 211 rotates at a uniform speed accordingly, and the structural design of the meshing between the drive shaft 43 and the inner edge gear ring 212 is adopted, so that the cross-sectional area of ​​the bubble forming frame 21 is increased, thereby increasing the effective bubble blowing diameter of the ring-shaped liquid collecting ring 211 connected to the bubble forming frame 21, and the volume of the bubbles blown through the liquid collecting ring 211 can be increased as much as possible without additionally increasing the diameter of the bubble forming frame 21, so that the bubble producing effect is better.

[0036] As a preferred embodiment, the power compartment 4 is equipped with a driving motor 41, and the two ends of the driving shaft of the driving motor 41 are respectively connected with a fan blade 411 and an output end gear 412. The blowing direction of the fan blade 411 is toward the wind guide frame 22, and the output end gear 412 is respectively engaged with the reversing tooth 431 and the extrusion tooth 133 through the relay gear set 42. The reversing tooth 431 rotates coaxially with the driving shaft 43, and the rod end of the driving shaft 43 away from the reversing tooth 431 is provided with a main wheel 432. The wind guide frame 22 is provided with an auxiliary wheel mounting shaft 224 for mounting an auxiliary wheel 44, and a drive shaft mounting groove 225 for supporting the driving shaft 43. Further, when the driving motor 41 rotates, it will synchronously drive The fan blades 411 and the output end gear 412 rotate, and the fan blades 411 will blow air toward the side of the air guide frame 22 when rotating, and when the output end gear 412 rotates, it first drives the relay gear set 42 to rotate, and then the reversing teeth 431 and the extrusion teeth 133 rotate respectively. When the reversing teeth 431 rotate, it drives the drive shaft 43 to rotate coaxially, and then the main wheel 432 and the inner edge gear ring 212 meshing with it rotate. While the bubble forming frame 21 rotates accordingly, the auxiliary wheel 44 provided on the air guide frame 22 assists the main wheel 432 in rotating to prevent it from shaking during the rotation process, thereby ensuring the smoothness of the relative rotation between the air guide frame 22 and the bubble forming frame 21.

[0037] As a preferred embodiment, a tube squeezer 13 is provided on the side of the shell 11, and the side cover of the tube squeezer 13 is provided with an end cover 134 with a reserved axial hole. A tooth core shaft 131 and two squeezing rods 132 are provided on the side of the squeezing tooth 133 facing the end cover 134. The tooth core shaft 131 is inserted into the axial hole reserved on the end cover 134, and the tube body of the infusion tube 3 away from the end of the liquid outlet 223 is placed in the gap between the squeezing rod 132 and the shell 11; further, the squeezing tooth 133 provided in the toy bubble blowing mechanism is driven by the relay gear set 42, and it rotates around the tooth core shaft 131 as the center. At this time, the two squeezing rods 132 rotate accordingly, continuously squeezing the infusion tube 3 provided in the gap between the shells 11, so that the bubble liquid is continuously squeezed and transported to the liquid outlet 223.

[0038] As a preferred embodiment, an injection hole 2231 is provided at one end of the liquid outlet 223 connected to the infusion tube 3, and a liquid outlet hole 2232 is also provided on the infusion tube 3, and several groups of scrapers 221 are provided on the air guide frame 22, which are on the same circle as the liquid outlet hole 2232. The vertical distance between the center position of the liquid collecting circle 211, the liquid outlet hole 2232 and the scraper 221 is consistent from the center of the bubble outlet 2; further, after the bubble liquid flows out through the liquid outlet 2232, the bubble liquid is smeared on the rotating liquid collecting circle 211. At this time, the excess bubble liquid on the liquid collecting circle 211 is scraped off by the scraper 221 to prevent the bubble liquid from accumulating too much on the liquid collecting circle 211 and affecting the bubble effect. When the liquid collecting circle 211 is rotating, after the wind from one side of the fan blade 411 blows through it, the bubble liquid accumulated on it is blown out to form bubbles, which fly out through the bubble outlet 2, and the liquid collecting circle 211 continuously passes through the liquid outlet hole 2232, thereby ensuring that the bubble liquid replenishment process on the liquid collecting circle 211 is not interrupted, so that the bubble effect is better.

[0039] The working process of the present invention is as follows: first, the infusion tube 3 is inserted into the bubble liquid tank, and the air blown out from one side of the air guide frame 22 is used to blow the bubble liquid transported to the bubble forming frame 21 through the infusion tube 3 to form rich bubbles, and under the driving action of the power warehouse 4, the bubble forming frame 21 rotates accordingly, preventing the bubble liquid from accumulating at the liquid outlet 223, and continuously and evenly transporting it to the bubble forming frame 21, and the liquid collecting ring 211 continuously passes through the liquid outlet hole 2232, thereby ensuring that the liquid replenishing process of the bubble liquid on the liquid collecting ring 211 is not interrupted, so that the bubble producing effect is better, and the fan blade 411 will blow air toward the side of the air guide frame 22 when rotating, and when the output end gear 412 rotates, it first drives the relay gear set 42 to rotate, thereby causing the reversing gear 431 and the extrusion gear 133 to rotate respectively, and when the reversing gear 431 rotates, it drives the drive shaft 43 to rotate coaxially, thereby causing the main wheel 432 and the inner edge gear ring 212 meshing therewith to rotate;

[0040] As the bubble forming frame 21 rotates, the auxiliary wheel 44 provided on the air guide frame 22 assists the main wheel 432 in rotating to prevent it from shaking during the rotation process, thereby ensuring the smoothness of the relative rotation between the air guide frame 22 and the bubble forming frame 21. The structural design of the engagement between the drive shaft 43 and the inner edge gear ring 212 increases the cross-sectional area of ​​the bubble forming frame 21, thereby increasing the effective bubble blowing diameter of the annular liquid collecting ring 211 connected to the bubble forming frame 21. While being driven by the relay gear set 42, the extrusion teeth 133 rotate around the tooth core shaft 131 as the center. At this time, the two extrusion rods 132 rotate accordingly, continuously squeezing the infusion tube 3 provided in the gap between the shell 11, so that the bubble liquid is continuously squeezed and transported to the liquid outlet 223. The above is the working principle of the toy bubble blowing mechanism.
