Embodiment Construction

[0060] Detailed description and technical content of the present invention, now just explain as follows with respect to matching drawing:

[0061] see Figure 1 to Figure 3 The present invention provides an air pump 100 with an external pressure relief valve. The air pump 100 includes an air pump body 10, a flow channel seat 20 and at least one air valve 30. The flow channel seat 20 is arranged on the air pump body 10. The air pump body 100 The valve 30 is connected to the flow channel seat 20 . Specifically, the air pump body 10 includes a drive motor 11 and at least one airbag group 12 that is actuated by the drive motor 11 and generates an output airflow. The airbag group 12 outputs the output airflow. The implementation of the drive motor 11 and the airbag group 12 can refer to the Chinese patent announcement number CN 206290397U and the Chinese patent application number CN 201810141741.X filed by the applicant, which will not be repeated here. repeat. On the other hand...

Abstract

The invention discloses an air pump provided with an external decompression valve. The air pump comprises an air pump body, a channel seat and at least one air valve, wherein the air pump body comprises a drive motor and at least one air sac group generating airflow; an airflow passage and a decompression passage are arranged on the channel seat; the decompression passage communicates with the airflow passage and extends to any side wall surface of the channel seat; a mounting hole of the decompression passage outlet is formed in the side wall surface; and a decompression component arranged inthe decompression passage is arranged through the mounting hole. According to the air pump, the decompression passage is arranged and extends to any side wall surface, so that the air pump can be connected with different to-be-inflated articles, and an assembling staff can easily adjust the output air pressure of the air pump.

Description

technical field [0001] The invention relates to an air pump with an external pressure relief valve, in particular to an air pump which utilizes a pressure relief channel which can extend to any side wall of the flow channel seat to facilitate users to adjust the pressure of the air pump. Background technique [0002] Due to the limited assembly space in a car seat in the automotive electronics industry, most of the air pumps now have a combined solenoid valve to reduce the volume. Specifically, the combined solenoid valve includes at least one solenoid valve and at least a pair of solenoid valves. The check valve should be set by the solenoid valve. The air pump is equipped with the related technology of the combined solenoid valve as disclosed in Chinese Patent No. CN102161321B and the like. The air pump includes at least one fluid chamber and a valve assembly communicating with the at least one fluid chamber, and the valve assembly includes a check valve and an electromag...
