Abstract

The invention discloses an air pump which comprises an upper cover, an air bag and an air outlet one-way valve. A first air exhaust channel is defined in the upper cover, an air outlet is formed in one end of the first air exhaust channel, a second air exhaust channel is defined in the air bag, the air bag is provided with a communicating opening communicating the first air exhaust channel and the second air exhaust channel, the air outlet one-way valve is arranged at the communicating opening and comprises a valve plate and a matching column, the valve plate is of a cylindrical structure and is integrally formed on the edge of the communicating opening, an inlet and an outlet are formed in the two axial ends of the valve plate respectively, and the matching column is tightly inserted into the inner side of the valve plate in a matched mode in the direction from the inlet to the outlet, so that the air outlet one-way valve guides airflow in the second air exhaust channel to the first air exhaust channel. The air pump is convenient to assemble and low in cost.

Description

technical field [0001] The invention relates to the technical field of fluid machinery, in particular to an air pump. Background technique [0002] The air pump has the functions of pumping air, boosting air, vacuuming, pressurizing, gas circulation, etc., and is widely used in various industries. In the related art, the assembly of the air pump is complicated and the cost is high. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention proposes an air pump, which is easy to assemble and low in cost. [0004] The air pump according to the embodiment of the present invention includes: an upper cover, defining a first exhaust channel inside the upper cover, and one end of the first exhaust channel forms an air outlet; an air bag, defining a second row of An air passage, and the air bag is formed with a communication port communicating with the first exhaust pa...
