Air compressor

Abstract

The invention discloses an air compressor, comprising at least one air pump, wherein the air pump is internally provided with a piston and an air cleaner installed at an air inlet, and further comprising an electrical motor, wherein the electrical motor comprises a stator and a magnetic core yoke, the center of the stator is provided with a through hole, the wall of the through hole is provided with at least one set of stator cores vertical to the axle of the through hole, the stator core is provided with a magnetic coil, the magnetic core yoke is provided with magnetic steel above two pairs of electrodes, the N pole and the S pole of the magnetic steel are set in alternating manner, the magnetic core yoke is installed inside the through hole, one end of the magnetic core yoke is providedwith at least one connecting bar connected with the piston of the air pump, and the magnetic core yoke is further provided with an elastic resetting device. The invention has the following advantage:the magnetic core yoke directly carries out reciprocating movement in the electrical motor to drive the piston by means of the advancement of the internal structure of the electrical motor, thereby efficiently improving the working efficiency, reducing the noises and prolonging the service life of the complete machine; and the reset position can be appointed by using the elastic resetting so as toconveniently re-start the air compressor.

Description

technical field [0001] The invention relates to an air compressor. Background technique [0002] Air is compressible, and the volume of the air is reduced by the mechanical movement of the air compressor, and the air after the pressure is increased is called compressed air. It is an important power source, and has the remarkable characteristics of no pollution, clear and transparent, convenient transportation, harmless, low flammability, and not afraid of loading. As an important form of energy generation, air compressors are widely used in machinery, metallurgy, electronic power, medicine, packaging, chemical industry, food, mining, textiles, transportation and many other industrial fields, becoming the mainstream product of compressed air. , is a device that outputs air at a standard atmospheric pressure through energy conversion to meet the needs of users. Energy conversion can generally be understood as the conversion of mechanical energy into kinetic energy. [0003] ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an air compressor, which can effectively solve the problems of low efficiency, high noise and low service life of the existing air compressors in which the rotary motor drives the piston or the swash plate to reciprocate through the reciprocating motion of the crankshaft connecting rod to make the plunger reciprocate. question
