Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0039] Figure 1 and Figure 2 The bubble blowing mechanism used in some embodiments of the present invention is shown. The bubble blowing mechanism is used to blow bubbles. The bubble blowing mechanism includes a housing 1, a drive device 2, a pumping device 3, a bubble producing device 7, and a fan 4. The drive device 2 is mounted on the housing 1; the fan is drivably connected to the drive device. The pumping device 3 is mounted on the housing 1 and drivably connected to the drive device 2.

[0040] As can be understood, housing 1 serves as a mounting and load-bearing mechanism. Drive device 2 is used to output torque. Pumping device 3 is used to pump liquid. Fan blades 4 are used to drive gas flow when rotating. Bubble device 7 is used to generate a bubble film, thereby producing bubbles when air flows through it.

[0041] like Figures 2 to 6 As shown, the bubble outlet device 7 includes a bubble nozzle 71, a transmission shaft 72 and a bubble-liquid stirring member 73. The bubble nozzle 71 is arranged on the shell, and the bubble nozzle 71 is connected to the pump liquid device 3. One end of the transmission shaft is driven and connected to the driving device 2, and the other end of the transmission shaft 72 is driven and connected to the bubble-liquid stirring member 73. The bubble-liquid stirring member 73 is rotatably arranged in the bubble nozzle 71. The bubble nozzle 71 has a bubble outlet 713 with a gradually decreasing cross-sectional area in the bubble outlet direction, and the bubble outlet 713 is funnel-shaped; when the fan blade 4 rotates, the airflow is driven to enter the bubble nozzle 71 and flow out through the bubble-liquid stirring member 73 and the bubble outlet 713.

[0042] It should be noted that one end of the drive shaft 72 is connected to the drive device 2 to receive torque, while the other end extends into the interior of the bubble nozzle 71 and connects to the bubble liquid stirring member 73, which is used to drive the bubble liquid stirring member 73 to rotate. The bubble liquid stirring member 73 is located in the bubble nozzle 71 and stirs the bubble liquid to ensure the production of fine and uniform foam. In particular, because the cross-sectional area of ​​the bubble outlet 713 gradually decreases in the bubble outlet direction, the foam will gradually converge as it moves within the bubble nozzle 71, preventing the bubble film from expanding, thereby making the blown foam more dense, concentrated, and continuous.

[0043] like Figures 2 to 6As shown, in some embodiments of the bubble blowing mechanism 10, the driving device 2 includes a dual-axis motor 21 and a gear transmission group, the dual-axis motor 21 is arranged on the shell 1, and the gear transmission group is arranged in the shell 1, and the first driving shaft 211 of the dual-axis motor 21 is arranged at one end away from the bubble nozzle 71 and parallel to the bubble nozzle 71, the first driving shaft 211 is driven and connected to the gear transmission group, the gear transmission group is driven and connected to one end of the transmission shaft, and the other end of the transmission shaft is driven and connected to the bubble-liquid stirring member 73; the liquid pumping device 3 is driven and connected to the gear transmission group.

[0044] As can be understood, the dual-axis motor 21 is fixedly mounted on the housing 1 and has two independently controlled drive shafts. The gear train is conventionally configured to include multiple sequentially meshing gears, thereby transmitting the torque of the dual-axis motor 21 at a predetermined transmission ratio and along a predetermined path. One end of the drive shaft is connected to the gear train, while the other end extends into the interior of the nozzle 71 and connects to the bubble liquid stirring member 73, driving the bubble liquid stirring member 73 to rotate.

[0045] like Figures 2 to 6 As shown, in some embodiments of the bubble blowing mechanism 10 , the gear transmission group includes a pump gear 23 , a transmission gear 24 and at least one reduction gear 22 ;

[0046] The first drive shaft 211 of the dual-axis motor 21 is driven and connected to the reduction gear 22, the reduction gear 22 is engaged with the pump gear 23, the pump gear 23 is engaged with the transmission gear 24, one end of the transmission shaft is driven and connected to the transmission gear 24, and the other end of the transmission shaft is driven and connected to the bubble liquid stirring member 73, and the pump liquid device 3 is driven and connected to the pump gear 23.

[0047] As will be understood, the reduction gear 22 is disposed within the housing 1 and is capable of freely rotating about its own axis. The first drive shaft 211 of the dual-shaft motor 21 is connected to the reduction gear 22 via a suitable mechanical connection (e.g., a keyway fit) to transmit power. The reduction gear 22, in turn, meshes with the pump gear 23, forming the next step in the power transmission chain. The pump gear 23 further meshes with the transmission gear 24 to achieve torque conversion.

[0048] It should be noted that the liquid pumping device 3 is directly mounted on the pump gear 23 . When the pump gear 23 rotates, the liquid pumping device 3 operates accordingly to extract the foam liquid and push it to the foam nozzle 71 .

[0049] like Figures 2 to 6 As shown, in some embodiments of the bubble blowing mechanism 10, the driving device 2 further includes two torque transmission sleeves 27, one of which is provided on the transmission gear 24, and the other is provided on the bubble-liquid stirring member 73;

[0050] A torque transmission part is provided at each end of the transmission shaft, and the two torque transmission parts are drive-connected to the two torque transmission sleeves 27 in a one-to-one correspondence.

[0051] It can be understood that the cooperation between the torque transmission part and the torque transmission sleeve, in addition to playing a transmission role, can also solve the connection problem of the two torque transmission parts not being on the same horizontal line.

[0052] It can be understood that both torque transmission sleeves 27 play a transmission role. When the transmission gear 24 rotates, it drives the torque transmission sleeve 27 to rotate, thereby driving the transmission shaft to rotate through the torque transmission part. The rotation of the transmission shaft will drive the other torque transmission sleeve 27 to rotate through the other torque transmission part, and then drive the stirring member 26 to rotate.

[0053] like Figures 2 to 6 As shown, in some embodiments of the bubble blowing mechanism 10, each torque transmission sleeve 27 is provided with a hexagonal hole 271, each torque transmission part includes a nut 722, and studs 721 are provided at both ends of the transmission shaft. The two nuts 722 are screwed onto the two studs 721 one by one, and each nut 722 is inserted into the two hexagonal holes 271 one by one.

[0054] As will be appreciated, the dimensions of the hexagonal hole 271 match the outer diameter of the nut 722, ensuring that the nut 722 can be securely inserted therein. The torque transmission unit includes a nut 722. This nut 722 has internal threads for threaded engagement with studs 721 at the ends of the drive shaft. Studs 721 are provided at each end of the drive shaft. These studs 721 have external threads that mate with the internal threads of the nut 722.

[0055] It should be noted that the nut 722 and the stud 721 can be configured to be fixedly connected, specifically by locking with threads, or by clamping and fixing with welding, bonding, or other clamping structures, thereby fixing the relative position and relative angle between the nut 722 and the transmission shaft, ensuring that the torque can be effectively fixed through the nut 722. In other embodiments, a non-threaded column can be used instead of the stud 721, and a hexagonal structure that can adapt to the hexagonal hole 271 can be provided on the column. The hexagonal structure placed in the hexagonal hole 271 can also achieve the purpose of torque transmission.

[0056] like Figures 2 to 6 As shown, in some embodiments of the bubble blowing mechanism 10 , the driving device 2 includes two transmission gears 24 ;

[0057] The driving device 2 also includes a transmission bevel gear 28 and a connecting shaft 29. One end of the connecting shaft 29 is connected to the transmission bevel gear 28, and the transmission bevel gear 28 is meshed with the pump gear 23. The other end of the connecting shaft 29 is connected to one of the transmission gears 24. The torque transmission sleeve 27 is set on the other transmission gear 24, and the two transmission gears 24 are meshed with each other.

[0058] It is understandable that the two transmission gears 24 mesh with each other to form a gear set that can change the direction of power transmission and adjust the speed and torque through an appropriate gear ratio to adapt to different work requirements.

[0059] The transmission bevel gear 28 is meshed with the pump gear 23, ensuring that the power from the pump gear 23 can be smoothly turned and transmitted to the connecting shaft 29. One end of the connecting shaft 29 is fixedly connected to the transmission bevel gear 28, and the other end is connected to one of the transmission gears 2, thereby forming a power transmission path from the pump gear 23 to the transmission gear 24. The torque transmission sleeve 27 is set on another transmission gear 24 that is not directly connected to the connecting shaft 29. In this way, the torque can be transmitted to the torque transmission sleeve 27 through the pump gear 23. Figures 1 to 6 As shown, in some embodiments of the bubble blowing mechanism of the present invention, the torque transmission sleeve 27 and the transmission gear 24 are an integrally formed structure.

[0060] It can be understood that the torque transmission sleeve 27 and the transmission gear 24 formed as one piece have a higher connection strength, thereby improving the durability of the product.

[0061] like Figures 2 to 6 As shown, in some embodiments of the bubble blowing mechanism 10, an air cavity 51 and an air duct 52 are opened on the shell 1; the fan blade 4 is located in the air cavity 51, the air duct 52 is respectively connected to the ventilation cavity 51 and the bubble nozzle 71, and the transmission shaft passes through the air duct 52.

[0062] It can be understood that the air cavity 51 has an opening for airflow to enter and is used to accommodate the fan blades 4; the air duct 52 is a channel connecting the air cavity 51 and the bubble nozzle 71. The air cavity 51 provides a relatively closed working environment for the fan blades 4, so that the fan blades 4 can effectively generate airflow when rotating.

[0063] The fan blades 4 are located in the air cavity 51 and are driven to rotate by the second drive shaft 212 of the dual-axis motor 21, thereby generating a stable airflow. Through the air duct 52, the airflow can carry the foam liquid delivered by the pump device 3 out of the foam nozzle 71 to form continuous and uniform foam.

[0064] like Figures 2 to 6 As shown, in some embodiments of the bubble blowing mechanism 10, the liquid pumping device 3 includes a pump body 32 and a liquid infusion tube. The pump body 32 is driven and connected to the gear transmission group to pump the bubble liquid to the bubble nozzle 71 through the liquid infusion tube.

[0065] It can be understood that after the pump body 32 receives the torque and operates, it will continuously pump the bubble liquid into the bubble nozzle 71 through the liquid infusion tube.

[0066] like Figures 2 to 6 As shown, in some embodiments of the bubble blowing mechanism 10, the bubble nozzle 71 is cylindrical, and the bubble nozzle 71 is also provided with a bubble-liquid joint 711 and a liquid guide channel 712. The pump body 32 is connected to the bubble-liquid joint 711, and the bubble-liquid joint 711 receives the bubble liquid and guides it to the liquid guide channel 712, so that the bubble liquid is guided to the bubble-liquid stirring member 73 via the liquid guide channel 712, and then bubbles are formed when the air flow flows through the bubble-liquid stirring member 73 and is discharged through the bubble outlet 713.

[0067] It can be understood that the bubble nozzle 71 is cylindrical in shape as a whole. This shape facilitates smooth airflow and even distribution of the foam liquid. The bubble liquid joint 711 is located at one end of the bubble nozzle 71 and is used to communicate with the pump body 32. The bubble liquid joint 711 receives the foam liquid from the pump body 32 and introduces it into the bubble nozzle 71. The liquid guide channel 712 connects the bubble liquid joint 711 and the bubble outlet 713, and is the flow path of the foam liquid in the bubble nozzle 71. The bubble outlet 713 is located at the other end of the bubble nozzle 71 and is where the foam is finally discharged. The bubble outlet 713 is for the discharge of bubbles.

[0068] like Figures 1 to 6 As shown, the bubble machine includes a bubble blowing mechanism 10, a liquid storage unit 8 and a power supply unit 9; the housing 1 includes a body 11 and an inner shell 12, the inner shell 12 is arranged in the body 11, the driving device 2, the pumping device 3, the bubble device 7 and the fan blade 4 are respectively arranged in the inner shell 12, the bubble device 7 is connected to the body 11, and the body 11 is provided with a grip portion 111;

[0069] The inner shell 12, the gripping portion 111, the liquid storage unit 8 and the power supply unit 9 are respectively arranged on the body 11 in radial order. The liquid storage unit 8 is connected to the liquid pumping device 3, the power supply unit 9 is electrically connected to the driving device 2, and a hanging part 13 is also provided on the body 11.

[0070] It can be understood that the liquid storage unit 8 is used to store the liquid for blowing bubbles. The power supply unit 9 is used to transmit electric energy to the driving device 2. The hanging member 13 is used to hang and fix the product.

[0071] like Figures 1 to 6 As shown, in some embodiments of the bubble blowing mechanism of the present invention, the bubble machine further includes a control switch 6 , which is electrically connected to the dual-axis motor 21 .

[0072] It is understood that the control switch 6 is disposed at an easily accessible location on the housing 1, such as an end face, side face, or other conveniently accessible location of the housing 1. The control switch 6 is electrically connected to the dual-axis motor 21 via a wire or other suitable electrical connection method. Thus, a user can control the start, stop, and operating status of the dual-axis motor 21 by operating the control switch 6.

[0073] It should be noted that the control switch 6 and the dual-axis motor 21 can be directly connected or connected through a circuit board.

[0074] The implementation of this utility model has at least the following beneficial effects:

High-quality foam not only increases the visual beauty, but also improves the durability and stability of the bubbles. The bubble outlet is configured as a funnel-shaped structure with a gradually decreasing cross-sectional area, so that the foam is gradually compressed and concentrated during the formation process. This feature helps to control the size and shape of the foam, reduces the random scattering of the foam, and is conducive to the production of bubbles with specific shapes or patterns.
