Air compressor

The invention discloses an air compressor which comprises an air cylinder, an air suction module, a one-way air inlet part and a one-way air outlet part. Particularly, an air inlet, an air outlet and an installing opening are formed in the air cylinder. The air suction module is arranged on the air cylinder and comprises a vibrating membrane, wherein the vibrating membrane seals the installing opening. The one-way air inlet part seals the air inlet. The one-way air outlet part is matched with the air outlet. By means of the air compressor, the low-cost, low-power-consumption and low-noise air compressor scheme is achieved, an air compressor structure is simplified, and the manufacturing cost of the air compressor is reduced. In addition, the power conversion is reduced, the energy utilization rate is improved, and the air compressor is energy-saving and environment-friendly.
