Micro compressor

Abstract

A micro compressor includes a motor with a driving gear and a fan respectively connected to the first and second ends thereof. A plastic-made frame is connected to the first end of the motor. A transmission device is connected to the frame and connected to the driving gear. A Nylon link is located in the frame and connected to the transmission device. A mount is connected to the frame and a cylinder cap is connected to the top of the mount. The mount is snapped to the frame. The compressor is light in weight and has lower manufacturing cost. The cylinder has a short travel with less noise.

What is claimed is: 
     
         1 . A micro compressor comprising:
 a motor;   a driving gear connected to a first end of the motor, a fan connected to a second end of the motor;   a frame connected to the first end of the motor, the frame being made by plastic;   a transmission device connected to the frame and connected to the driving gear, a Nylon link located in the frame and connected to the transmission device, and   a mount being snapped to the frame and a cylinder cap connected to a top of the mount.   
     
     
         2 . The micro compressor as claimed in  claim 1 , wherein the transmission device comprises a driven gear which is engaged with the driving gear, a cam is connected to the driven gear and has an eccentric shaft which is connected with an eccentric wheel, the eccentric wheel is connected to the Nylon link by a plane bearing. 
     
     
         3 . The micro compressor as claimed in  claim 2 , wherein the eccentric shaft is connected to the frame by a needle bearing. 
     
     
         4 . The micro compressor as claimed in  claim 1 , wherein the frame comprises a left part and a right part, the left and right parts are respectively located on two sides of the Nylon link. 
     
     
         5 . The micro compressor as claimed in  claim 1 , wherein the cylinder cap is made by plastic.
