Rotation type air compressor

Abstract

The invention discloses a rotation type air compressor which comprises a rotor, a shell, an air inlet and an air outlet, wherein a shell chamber which can compress air is formed between the rotor and the shell; the rotor is arranged inside the shell chamber in an eccentric manner; an airtight contact part is arranged between one side of the rotor and the lower side of the shell chamber; the air inlet and the air outlet are respectively formed in two sides of the airtight contact part; end part sealing devices are arranged at two ends of the shell chamber; a rotor groove is formed in the rotor; a tongue piece device which makes reciprocation movement inside the rotor groove is arranged in the rotor groove; the end part of a tongue piece of the tongue piece device is always in airtight contact with the inner wall of the shell chamber of the shell and can compress the air inside the shell chamber when the rotor rotates. When the air compressor operates, as the rotor is arranged in the eccentric manner, one side of the rotor is in airtight contact with the shell chamber, and the tongue piece device makes reciprocation movement inside the rotor groove when the rotor rotates, the air sealed in the shell chamber is compressed, high pressure air is discharged from the air outlet, meanwhile, the air is sucked in through the air inlet, and the purpose of acquiring compressed air is achieved in the circulation and reciprocation movement.

Description

technical field [0001] The invention relates to an air compression device, in particular to an air compressor which rotates and outputs compressed gas. Background technique [0002] Most of the current air compressors are driven by a motor to reciprocate the piston, use the intake valve to inhale air, the piston reciprocates to generate high-pressure gas, and use the exhaust valve to discharge the high-pressure gas. The cylinder piston has a relatively complex structure, its effective working stroke is relatively short, and its working efficiency is relatively low. During the working process, the piston has to overcome the inertia of the reciprocating cycle, and the direction of the piston's movement changes frequently, so it has a large impact, which will generate a large noise during work, and when the intake valve is used to intake air, it will also produce noise. .

Problems solved by technology

The cylinder piston has a relatively complex structure, its effective working stroke is relatively short, and its working efficiency is relatively low

During the working process, the piston has to overcome the inertia of the reciprocating cycle, and the direction of the piston's movement changes frequently, so it has a large impact, which will generate a large noise during work, and when the intake valve is used to intake air, it will also produce noise.

[0003] The disclosed air compressor adopts rotary drive, the driving structure of the rotary tongue is complex, the movement reliability is not high, and because the expansion and contraction of the tongue requires a large space, no effective output will be performed during the expansion and contraction of the tongue, and the expansion and contraction Due to the existence of high-pressure gas in the process, there will be a lot of gas impact noise

[0004] From the above analysis, it can be seen that the existing reciprocating piston air compressors and rotary tongue air compressors have disadvantages such as complex structure, low working efficiency, and high working noise.
