Air compressor

Abstract

This invention relates to an air pump, which includes a cover element, a compression mechanism, and a power mechanism. The cover element has an air inlet chamber and a first air inlet end, the first air inlet end being in communication with the air inlet chamber; the compression mechanism has a connecting chamber communicating with the outside, the first air inlet end extending into the connecting chamber and directly communicating with the connecting chamber; the power mechanism is connected to the compression mechanism and is used to drive the compression mechanism to operate. By extending the first air inlet end into the connecting chamber and directly communicating with it, the air inlet path of the air pump is shortened, gas loss during transmission is reduced, and the reliability and efficiency of the air pump are improved.
