Background

When the piston of the piston type air compressor reciprocates in the cylinder, the pressure of the left cavity of the piston in the cylinder is lower than the atmospheric pressure when the piston moves rightwards, the suction valve is opened, and the outside air is sucked into the cylinder, and the process is called as a compression process. When the pressure in the cylinder is higher than the pressure in the output air pipeline, the exhaust valve is opened. The reciprocating motion of the piston is formed by a slider-crank mechanism driven by an electric motor. The rotary motion of the crank is converted into the reciprocating motion of the piston.

In the prior patent (No. CN212615236U), a piston type air compressor ensures the convenient moving effect of the main body of the piston type air compressor by a pulling and moving component consisting of a connecting rod, a connecting block, a handle bar, a first rod block, a second rod block and other components, and the like, and the existence of a guide roller is matched, so that the pulling and moving component can be quickly recovered by utilizing the opening of a rod groove in a casing and the telescopic effect between the first rod block and the second rod block, does not occupy working space and has certain adjusting capability, and the rotating design of the connecting block, the handle bar and the first rod block and an anti-skid sleeve wrapped outside the handle bar can effectively reduce the vibration feeling of the hands of a person when the bottom of the main body of the piston type air compressor is vibrated, and when the person holds a handle on one side different from the connecting block, the handle bar is slightly lifted upwards to perform labor-saving position deflection operation on the main body of the piston type air compressor by taking the disk block as a rotating point, the auxiliary convenience maintenance personnel carry out corresponding observation and treatment, and the normal and efficient use and operation of the piston type air compressor are guaranteed.

In carrying out the above invention, the inventors found that at least the following problems are not solved:

1. when the air compressor runs for a long time, the piston moves back and forth in the piston cavity, more heat is generated due to continuous friction with the inner wall, and the sealing ring on the piston, the air inlet plug and the air outlet plug are deformed due to continuous accumulation of heat, so that the equipment cannot run normally;

2. the elasticity effect of the spring that the help was admitted air and is filled in and give vent to anger the stopper and reset is all fixed, can not adjust, the phenomenon that the spring in the air compressor machine used for a long time can the primary election become soft, and then the normal reset that influences the stopper of admitting air and giving vent to anger, this also can influence the efficiency of admitting air and giving vent to anger, secondly, when the air compressor machine long-term operation, the stopper of admitting air and giving vent to anger the stopper and constantly carry out reciprocating motion, soft rubber is generally adopted to the material of the two, easily the breakage appears, and then the condition that the exhaust is admitted air inefficiency appears.

To this end, a piston air compressor is proposed.
