Micro high-pressure air compressor

A micro high-pressure air compressor comprising a housing and an air compression mechanism and a drive mechanism mounted in the housing, characterized in that, the air compression mechanism includes a low-pressure cylinder, a high-pressure cylinder, a primary piston, a secondary piston, a piston rod and a pressure cylinder;

• the high-pressure cylinder is mounted in the low-pressure cylinder coaxially, and fixed on the first end of the low-pressure cylinder to form an annular piston chamber between the low-pressure cylinder and the high-pressure cylinder;
• the primary piston is mounted in the annular piston chamber to separate the annular piston chamber into a suction chamber and a compression chamber;
• the secondary piston is mounted in the high-pressure cylinder;
• the piston rod is penetrated into the low-pressure cylinder from the second end of the low-pressure cylinder;
• the piston rod includes a sleeve and an inner rod;
• the sleeve of the piston rod is covered on the high-pressure cylinder and connected to the primary piston;
• the inner rod of the piston rod is inserted into the high-pressure cylinder and connected to the secondary piston;
• the low-pressure cylinder is equipped with an air inlet of the suction chamber, an air inlet of the high-pressure cylinder and an air outlet of the high-pressure cylinder on the first end;
• the low-pressure cylinder is equipped with an air outlet of the compression chamber at the second end;
• the pressure cylinder is equipped with an air inlet and an air outlet;
• the air inlet of the pressure cylinder is connected with the air outlet of compression chamber and the air outlet of the pressure cylinder connected with the air inlet of the high-pressure cylinder through the gas tube;
• the air inlet of the suction chamber is equipped with a primary one-way valve;
• the primary piston is equipped with a secondary one-way valve connecting the suction chamber and compression chamber;
• a third one-way valve is mounted between the air outlet of the compression chamber and the air inlet of the pressure cylinder;
• a fourth one-way valve is mounted between the air outlet of pressure cylinder and the air inlet of high-pressure cylinder;
• the air outlet of the high-pressure cylinder is equipped with a fifth one-way valve;
• the drive mechanism drives the piston rod to enable the primary piston and the secondary piston to perform piston movement in the annular piston chamber and high-pressure cylinder respectively.
