Abstract

The invention relates to oilless air compressors, and provides a cooling type oilless air compressor main body structure provided with a piston for air inflow. The cooling type oilless air compressor main body structure provided with the piston for air inflow comprises a crankcase, a compression cylinder and a crankshaft. The compression cylinder comprises a cylinder body, a cylinder cover and the piston, wherein one end of the cylinder body is connected with the crankcase, the cylinder cover covers the other end of the cylinder body and is provided with an exhaust hole, and the piston is located in the cylinder body; and a compression cavity is formed between the piston and an exhaust assembly, the exhaust assembly is arranged between the piston and the cylinder cover, and the piston is connected with the crankshaft through a connecting rod. The compression cylinder is sleeved with a cooling channel communicating with the crankcase. The piston is provided with an air inlet channel communicating with the crankcase and the compression cavity, and the air inlet channel is provided with a one-way valve which can be opened towards the compression cavity. The crankcase is provided with an air inlet, and the crankshaft is provided with an air inlet fan driving air flow to flow through the air inlet to enter the crankcase. The cooling type oilless air compressor main body structure provided with the piston for air inflow has the advantages that air inflow is achieved through the piston, and the compression cylinder can be cooled, and the problems that an air inlet component and an air outlet component of an existing oilless air compressor are seriously affected by each other, and the temperature of a compression cylinder is high are solved.

Description

technical field [0001] The invention relates to an oil-free air compressor, in particular to a main body structure of a piston air intake and heat dissipation type oil-free air compressor. Background technique [0002] An air compressor is a device used to generate compressed air. Air compressors are mainly composed of screw air compressors and oil-free air compressors. The air intake and exhaust of the existing oil-free air compressor are all on the cylinder head, which leads to high temperature of the cylinder head and affects the life of the air intake and exhaust components of the air compressor. Contents of the invention [0003] The present invention provides a piston air intake and heat dissipation type oil-free air compressor host structure through the piston air intake and heat dissipation for the compression cylinder, which solves the problem of the large mutual influence of the air inlet and outlet parts of the existing oil-free air compressor and the high temp...
