[0002] In modern industry and daily life, air pumps have become one of the indispensable equipment, widely used in the inflation needs of automobile tires, air mattresses, sports equipment, etc. The existing air pump technology mainly relies on the straight gear movement, which meets the market demand to a certain extent, but also has obvious shortcomings.

[0003] The existing spur gear movement air pump has the following main problems:

[0004] The movement structure is larger:

[0005] Due to the low space utilization efficiency of the straight tooth design, the overall movement structure is larger, which not only increases the volume and weight of the air pump, but also limits the application of the air pump in some compact spaces;

[0006] Lack of deflate function:

[0007] Most air pumps on the market do not have a deflation function. During use, users need additional tools or equipment to perform the deflation operation after inflation, which increases the complexity and inconvenience of use. Summary of the invention

[0008] In order to solve the above problems, the utility model provides an air pump turbine gear movement with a deflation function, which not only optimizes the space utilization efficiency, but also integrates an air release valve, greatly improving the practicality and convenience of the air pump.

[0009] The utility model is realized by the following technical scheme: an air pump turbine gear movement with a deflation function, comprising:

[0010] A pump body, wherein an air outlet is arranged at one end of the pump body, a sealing plug is arranged at the other end corresponding to the air outlet, and a connecting rod is arranged at the other end of the sealing plug;

[0011] An air release valve assembly is arranged on one side of the pump body and is used to release air from the pump body;

[0012] A bracket, on which a spiral toothed disc with tooth grooves facing downward is rotatably mounted, and an eccentric connecting shaft is provided on the spiral toothed disc, and the eccentric connecting shaft is connected to the connecting rod;

[0013] The motor has turbine gears installed on its driving shaft. The turbine gears extend into the bracket and mesh with a circle of teeth on the lower end surface of the spiral gear disk for transmission.

[0014] As a preferred technical solution, the upper end surface of the bracket is provided with a gear installation cavity, the center of the spiral gear plate is provided with a gear shaft, and the spiral gear plate is rotatably connected to the bracket through the gear shaft.

[0015] As a preferred technical solution, a bearing is embedded in the bottom surface of the gear installation cavity, and the gear shaft is installed in the bearing.

[0016] As a preferred technical solution, a spring is provided in the pump body near the air outlet, a mushroom head plug is mounted on the spring, the spring applies elastic force to the mushroom head plug, and the mushroom head plug seals the air hole inside the pump body.

[0017] As a preferred technical solution, a piston cavity is formed on one side of the pump body corresponding to the sealing plug, a sealing ring is provided on the outer wall of the sealing plug, and the sealing ring and the sealing plug are sealed and installed in the piston cavity.

[0018] As a preferred technical solution, the motor is a dual-axis motor, and a centrifugal fan is installed on the side of the motor facing away from the turbine teeth.

[0019] As a preferred technical solution, a sensor tube is further provided on the pump body, a sensor is installed in the sensor tube, and the sensor tube is communicated with the interior of the pump body.

[0020] The beneficial effects of the utility model are as follows: the utility model can greatly reduce the height of the gear plate and the connecting rod by selecting the turbine teeth with the gear plate facing downward, and the connecting rod is also made into an eccentric structure, so the utility model significantly reduces the overall thickness and volume of the movement, making the air pump more compact, suitable for various application scenarios that require space saving, and easy to carry and store;

[0021] The turbine teeth not only optimize space utilization, but also improve transmission efficiency. Compared with traditional straight teeth, the turbine tooth design can transmit power more quickly, allowing the air pump to complete the inflation operation in a shorter time, thus improving the working efficiency of the equipment.

[0022] The utility model integrates a deflation valve on the basis of a traditional air pump, and can achieve deflation after inflation through simple operation without the need for additional tools, thereby greatly improving user experience and operational convenience and avoiding the inconvenience of using a traditional air pump.
