Air compression device and air compressor

Abstract

The invention provides an air compression device and an air compressor, pertaining to the technical field of air compression with the purpose of solving the problem that a conventional air compressor has poor compression effect. The air compression device comprises an air cylinder, a piston and a piston rod. The piston and the piston rod are arranged in the air cylinder. The air cylinder is provided with an air inlet and an air outlet. The piston has an inner cavity, in which a connecting rod is arranged. One end of the piston rod is arranged onto the connecting rod in a sleeving mode. The lower end of the piston is provided with an opening, in which multiple air inlet holes are formed. The air inlet holes are communicated with the air inlet by means of the inner cavity and the opening at the lower end. A diaphragm leaf base is arranged in the air cylinder. The upper end of the piston is provided with an air inlet diaphragm leaf enabling the air inlet holes to be sealed with or communicated with an above compression cavity. The upper end of the diaphragm leaf base is provided with multiple air outlet holes enabling the above compression cavity to be communicated with the air outlet of the air cylinder. The upper end of the diaphragm leaf base is provided with an air outlet diaphragm leaf. The air compression device is advantaged by being fine in air compression effect, high in efficiency and long in service lifetime.

Description

technical field [0001] The invention belongs to the technical field of air compression, and relates to an air compression device and an air compressor. Background technique [0002] At present, there are many types of air compressors, such as piston compressors, rotary compressors, and vane compressors. Most air compressor chambers adopt the reciprocating piston type. The compression element is a piston, which reciprocates in the cylinder to compress the air. The piston and cylinder structure adopts the existing common cylinder piston structure. The existing problems are: The existing common cylinder-piston structure is not effective when entering and exiting air, so that the air compression effect is not good. Contents of the invention [0003] The object of the present invention is to propose an air compression device for compressing air with high efficiency and high effect in view of the above-mentioned problems in the prior art. [0004] The purpose of the present in...
