Description

Technical Field

[0001] The utility model belongs to the technical field of air pumps, in particular to an air pump. Background Art

[0002] As a gas compression and inflation device, the technical background of the air pump is to solve the problems of low efficiency and cumbersome operation of traditional inflation methods. With the development of science and technology, modern air pumps adopt advanced blowing components and pressure buffer components. The blowing component realizes one-way flow of air through a one-way valve to ensure that the air will not flow back during the inflation process. At the same time, the pressure buffer component is equipped with a sensor that can monitor the pressure in the cavity in real time. When the pressure reaches the preset value, the blowing motor stops working through intelligent control and the first air valve is closed. Subsequently, the pressurized motor starts, drives the piston movement through the gear transmission system and the eccentric block, realizes efficient air compression, and sends the compressed air into the pressure buffer component through the second air valve, and finally inflates the inflatable product. This design not only improves the inflation efficiency, but also ensures the safety and stability of inflation.

[0003] In the process of implementing this application, it was found that the technology has the following problems: the existing air pump is not equipped with a component for real-time air pressure detection, and cannot accurately grasp the air pressure changes during the inflation process, which may lead to over-inflation or under-inflation, affecting the inflation efficiency and increasing safety risks.

[0004] For this purpose, an air pump is proposed. Utility Model Content

[0017] 1. In the utility model, when an air pump is used to inflate an inflatable product, during the inflation process, after the blowing component is started, the air flow will enter through the first air valve, and then be released from the air outlet of the pressurized plastic part to provide inflation for the inflatable product. When the inflation operation stops, since the first air valve is designed as a one-way valve, the air in the pressure buffer component cannot flow back. The pressure buffer component is provided with a through hole connected to the sensor, which can detect the air pressure in real time. The first air valve is provided to prevent air leakage, and the air pressure changes during the inflation process can be accurately grasped to ensure that it will not be over-inflated or under-inflated, thereby improving the inflation efficiency.

Then, the pressurizing motor starts working, driving the large gear through the small gear to achieve a deceleration effect, and then connects the piston rod through the eccentric block to reciprocate inside the cylinder assembly to compress the air. The compressed air will pass through the second air valve and enter the pressure buffer component again to further inflate the inflatable product. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The implementation principle of an air pump embodiment of the present application is:

[0033] When an air pump is used to inflate an inflatable product, during the inflation process, after the blowing component 2 is started, the air flow will enter through the first air valve 12, and then be released from the air outlet of the pressurized plastic part 7 to provide inflation for the inflatable product. When the inflation operation stops, since the first air valve 12 is designed as a one-way valve, the air in the pressure buffer component cannot flow back. The pressure buffer component 103 is provided with a through hole connected to the sensor, which can detect the air pressure in real time. The first air valve 12 can prevent air leakage and can accurately grasp the air pressure changes during the inflation process to ensure that there will be no over-inflation or under-inflation, thereby improving the inflation efficiency. The pressurizing component and the blowing component are convenient for loading and unloading through the snap-fit ​​limit connection, and the snap-fit ​​connection is more efficient than screws.

[0034] On the other hand, the pressure buffer component 103 is equipped with a through hole connected to the sensor. When the sensor detects that the pressure in the cavity of the component reaches the preset 0.6PSI, the 390 motor 11 will automatically stop working, and the first air valve 12 will be closed. Then, the pressurizing motor 5 starts working, driving the large gear 27 through the small gear 32 to achieve a deceleration effect, and then connects the piston pull rod 20 through the eccentric block 25, and reciprocates inside the cylinder assembly 102 to compress the air. The compressed air will pass through the second air valve 15 and enter the pressure buffer component 103 again to further inflate the inflatable product.
