FIGS. 1 and 2 show a bubble blowing mechanism in some embodiments of the present disclosure, which is used to blow out bubbles. The bubble blowing mechanism includes a housing 1, a driving device 2, a pumping liquid device 3, a bubbling device 7, and a fan blade 4. The driving device 2 is provided on the housing 1; the fan blade is connected to the driving device 2. The pumping liquid device 3 is provided on the housing 1, and the pumping liquid device 3 is connected to the driving device 2.

It can be understood that housing 1 plays a role in installation and load-bearing. The driving device 2 is used to output torque. The pumping liquid device 3 is used for pumping liquids. The fan blade 4 is used to drive gas to flow when it is rotated. The bubbling device 7 is used to generate a bubble film, thereby producing bubbles when the airflow blows through.

As shown in FIGS. 2 to 6, the bubble device 7 includes a bubble nozzle 71, a transmission shaft 72, and a foaming liquid stirring element 73. The bubble nozzle 71 is provided on the housing 1 and is communicated to the pumping liquid device 3. One end of the transmission shaft 72 is connected to the driving device 2, and the other end of the transmission shaft 72 is connected to the foaming liquid stirring element 73. The foaming liquid stirring element 73 is rotatably provided in the bubble nozzle 71. The bubble nozzle 71 includes a bubble outlet 713 with a gradually decreasing cross-sectional area in a direction of bubble formation, and the bubble outlet 713 is a funnel structure; when the fan blade 4 is rotated, it drives airflow into the bubble nozzle 71 and flows out through the foaming liquid stirring element 73 and the bubble outlet 713.

It should be noted that one end of the transmission shaft 72 is connected to the driving device 2 to receive torque, and the other end thereof is extended to an interior of the bubble nozzle 71 and is connected to the foaming liquid stirring element 73 to drive the foaming liquid stirring element 73 to rotate. The foaming liquid stirring element 73 is located in the bubble nozzle 71, which plays the role of stirring bubble liquid to ensure produced bubbles are fine and even. In particular, since the sectional area of the bubble outlet 713 in the foaming direction gradually decreases, the bubbles will gradually gather in a process of moving in the bubble outlet 71 to avoid an expansion of the bubble film, thus rendering blown bubbles more dense, concentrated and continuous.

As shown in FIGS. 2 to 6, in some embodiments of the bubble blowing mechanism 10, the driving device 2 includes a dual axis motor 21 and a gear transmission assembly. The dual axis motor 21 is provided on the housing 1, the gear transmission assembly is provided in the housing 1. A first driving shaft 211 of the dual axis motor 21 is provided at one end away from the bubble nozzle 71 and parallel to the bubble nozzle 71. The first driving shaft 211 is connected to the gear transmission assembly, which is connected to one end of the transmission shaft, and the other end of the transmission shaft is connected to the foaming liquid stirring element 73; the pumping liquid device 3 is connected to the gear transmission assembly.

It can be understood that the dual axis motor 21 is fixedly provided on the housing 1 and has two independently controlled driving shafts. The gear transmission assembly is an existing technology that can be configured to include multiple sequentially meshing gears, thereby transmitting a torque of the dual axis motor 21 at a predetermined transmission ratio and predetermined path. One end of the transmission shaft is connected to the gear transmission assembly, and the other end thereof is extended to the interior of the bubble nozzle 71 and is connected to the foaming liquid stirring element 73 so as to drive the foaming liquid stirring element 73 to rotate.

As shown in FIGS. 2 to 6, in some embodiments of the bubble blowing mechanism 10, the gear transmission assembly includes a pump gear 23, a transmission gear 24, and at least one reduction gear 22.

The first driving shaft 211 of the dual axis motor 21 is 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 connected to the transmission gear 24, and the other end of the transmission shaft is connected to the foaming liquid stirring element 73. The pumping liquid device 3 is connected to the pump gear 23.

It can be understood that the reduction gear 22 is provided in the housing 1 and can freely rotate around its own axis. The first driving shaft 211 of the dual axis motor 21 is connected to the reduction gear 22 through a suitable mechanical connection (such as keyway fitting) to transmit power. The reduction gear 22 is further engaged with the pump gear 23 to form a next power transmission chain. The pump gear 23 is further engaged with transmission gear 24 to achieve torque conversion.

It should be noted that the pumping liquid device 3 is directly provided on the pump gear 23. When the pump gear 23 is rotated, the pumping liquid device 3 acts accordingly to extract the bubble liquid and push it to the bubble nozzle 71.

As shown in FIGS. 2 to 6, 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 torque transmission sleeve 27 is provided on the foaming liquid stirring element 73.

Two ends of the transmission shaft are provided with a torque transmission part, and two torque transmission parts are correspondingly connected to the two torque transmission sleeves 27.

It can be understood that by a cooperation between the torque transmission part and the torque transmission sleeves, which plays a transmission role, it can also solve a problem of connecting two torque transmission parts that are not on the same horizontal line.

It can be understood that the two torque transmission sleeves 27 both play a role in transmission. When the transmission gear 24 is rotated, it drives the torque transmission sleeves 27 to rotate, thereby driving the transmission shaft to rotate through the torque transmission part. A rotation of the transmission shaft will drive another torque transmission sleeve 27 to rotate through another torque transmission part, thereby driving a stirring element 26 to rotate.

As shown in FIGS. 2 to 6, in some embodiments of the bubble blowing mechanism 10, each of the torque transmission sleeves 27 is provided with a hexagonal hole 271, and each of the torque transmission parts includes a nut 722. Two ends of the transmission shaft are provided with bolts 721, and two nuts 722 are screwed onto the two bolts 721 one by one, and each of the nuts 722 is inserted into two hexagonal holes 271 one by one.

It can be understood that a size of the hexagonal hole 271 matches outer diameters of the nuts 722, ensuring that the nuts 722 can be securely inserted into it. The torque transmission part includes one nut 722. The nut 722 has internal threads for screwing with the bolt 721 at an end of the transmission shaft. The two ends of the transmission shaft are respectively provided with bolts 721. The bolts 721 have external threads that match the internal threads of the nuts 722.

It should be noted that the nuts 722 and the bolts 721 can be configured as a fixed connection, which can be locked by threads, or clamped and fixed by welding, bonding, or other clamping structures to fix relative position and angle of the nuts 722 and the transmission shaft, ensuring that the torque can be effectively fixed through the nuts 722. In other ways, a non-threaded cylinder can be used instead of the bolts 721, and a hexagonal structure that can be adapted to the hexagonal hole 271 can be provided on the cylinder, which can also achieve the purpose of torque transmission by being placed in the hexagonal hole 271.

As shown in FIGS. 2 to 6, in some embodiments of the bubble blowing mechanism 10, the driving device 2 includes two transmission gears 24.

The driving device 2 further includes a transmission bevel gear 28 and a connection shaft 29. One end of the connection shaft 29 is connected to the transmission bevel gear 28, the transmission bevel gear 28 is engaged with the pump gear 23. The other end of the connection shaft 29 is connected to one of the transmission gears 24. The torque transmission sleeves 27 are provided on the other transmission gear 24, and the two transmission gears 24 are engaged with each other.

It can be understood that the two transmission gears 24 are engaged with each other to form a gear assembly. This gear assembly can change power transmission direction and adjust speed and torque through an appropriate gear ratio to meet different work requirements.

The transmission bevel gear 28 is engaged with the pump gear 23, ensuring that the power from the pump gear 23 can be smoothly turned and transmitted to the connection shaft 29. One end of the connection shaft 29 is fixedly connected to the transmission bevel gear 28, and the other end thereof is connected to one of the transmission gears 2, thus forming a power transmission path from the pump gear 23 to the transmission gear 24. The torque transmission sleeves 27 are provided on another transmission gear 24 that is not directly connected to the connection shaft 29. In this way, torque can be transmitted to the torque transmission sleeves 27 through the pump gear 23. As shown in FIGS. 1 to 6, in some embodiments of the bubble blowing mechanism of the present disclosure, the torque transmission sleeves 27 and the transmission gear 24 are integrally formed structures.

It can be understood that the torque transmission sleeve 27 and the transmission gear 24, which are integrally formed together, have higher connection strength, thereby improving the durability of the product.

As shown in FIGS. 2 to 6, in some embodiments of the bubble blowing mechanism 10, the housing 1 is provided with an air chamber 51 and an air duct 52. The fan blade 4 is located in the air chamber 51, and the air duct 52 is respectively connected to the air chamber 51 and the bubble nozzle 71 respectively. The transmission shaft passes through the air duct 52.

It can be understood that the air chamber 51 has an inlet for air flow to accommodate the fan blade 4. The air duct 52 is a channel connecting the air chamber 51 and the bubble nozzle 71. The air chamber 51 provides a relatively enclosed working environment for the fan blade 4, enabling it to effectively generate airflow when it is rotated.

The fan blade 4 is located in the air chamber 51 and is driven to rotate by a second drive shaft 212 of the dual axis motor 21, thereby generating a stable airflow. Through the air duct 52, the air flow can bring the bubble liquid delivered from the pumping liquid device 3 out of the bubble nozzle 71 to form continuous and uniform bubbles.

As shown in FIGS. 2 to 6, in some embodiments of the bubble blowing mechanism 10, the pumping liquid device 3 includes a pump body 32 and an infusion tube. The pump body 32 is connected to the gear transmission assembly, and the bubble liquid is pumped to the bubble nozzle 71 through the infusion tube.

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

As shown in FIGS. 2 to 6, in some embodiments of the bubble blowing mechanism 10, the bubble nozzle 71 is cylindrical, and the bubble nozzle 71 is further provided with a bubble joint 711 and a liquid guide channel 712. The pump body 32 is communicated to the bubble joint 711, and the bubble joint 711 is connected and guides the bubble liquid to the liquid guide channel 712, so that the bubble liquid is guided to the foaming liquid stirring element 73 through the liquid guide channel 712. When the airflow flows through the foaming liquid stirring element 73, bubbles are formed and discharged through the bubble outlet 713.

It can be understood that the bubble nozzle 71 is in a cylindrical shape as a whole, which facilitates a smooth passage of the air flow and a uniform distribution of the bubble liquid. The bubble joint 711 is located at one end of the bubble nozzle 71 and is used to communicate with the pump body 32. The bubble joint 711 receives bubble liquid from the pump body 32 and introduces it into the bubble nozzle 71. The liquid guide channel 712 is connected with the bubble joint 711 and the bubble outlet 713, which is a flow path of the bubble liquid in the bubble nozzle 71. The bubble outlet 713 is located at the other end of the bubble nozzle 71, which is a place where the bubbles are finally discharged. The bubble outlet 713 is used to discharge the bubbles.
