Air pump with dust removal and anti-blocking structure

Abstract

An air pump with a dust removal and anti-blocking structure, including a pump body. The pump body is provided with a main air intake hole, an air intake chamber, and an air outlet chamber. , the main air intake hole is provided with a first valve body, the pump body is provided with an air intake sleeve connected with the main air intake hole, the air intake sleeve is provided with a filter screen, and the air intake chamber is provided with a movable baffle, The side wall of the air intake cavity is provided with auxiliary air intake holes, the bottom wall of the air intake cavity is provided with a dust removal air hole communicating with the air intake chamber, and the other end of the dust removal air hole and the main air intake hole are located on the outside of the first valve body. The parts are connected, the main air intake hole and the exhaust hole are used together as the first unit, the auxiliary air intake hole and the dust removal air hole are used together as the second unit, and the movable baffle blocks the first unit or the second unit in an optional way. There is a push screw used to adjust the movable baffle, and the invention can use the power of the air pump itself to carry out back blowing and dust removal without replacing and disassembling the filter screen. The structure is ingenious and easy to clean.

Description

technical field [0001] The invention belongs to the technical field of dust prevention for air pump air inlets. Background technique [0002] Air pump, that is, "air pump", is a device that removes air from a closed space or adds air to a closed space. In use, the air inlet of the air pump will draw air from the outside for compression, but in many cases the working environment of the air pump is It is not so clean, too much dust particles in the air will block the air inlet and cause the air pump to fail. The existing air pump filter device simply adds filters and other devices, which need to be disassembled, cleaned and replaced after long-term use , is very troublesome, and now an easy-to-clean air pump filter device is provided to solve this problem. Contents of the invention [0003] The object of the present invention is to provide an air pump with a dust removal and anti-blocking structure, which can use the power of the air pump itself to carry out back blowing an...
