[0035] When the compressor 100 is working, the driver 120 is started, and the crankshaft 130 is driven to rotate by the driver 120. The crankshaft 130 rotates to drive the piston rod 142 to move through the eccentric shaft 131, and the piston rod 142 drives the piston member to perform reciprocating linear motion in the cylinder body 141, so that the gas that is pressurized and delivered to the cylinder 140 by the suction device 150 is transmitted to the outside of the shell 110 through the cylinder 140 to achieve gas compression.

[0037] Specifically, when assembling the compressor 100 of the present application, the driver 120, the crankshaft 130 and the cylinder 140 are first installed in the housing 110, and the driver 120, the crankshaft 130 and the cylinder 140 are connected by transmission. Then, the adapter 153 is installed on the eccentric shaft 131 of the crankshaft 130, the impeller 152 is installed on the adapter 153, and the suction housing 151 is installed outside the impeller 152. When the impeller 152 and the eccentric shaft 131 are connected by the adapter 153, the first connection portion is connected to the impeller 152. 1532 is connected to the eccentric shaft 131, the second connecting part 1533 is connected to the impeller 152, and the distance between the first connecting part 1532 and the second connecting part 1533 is equal to the eccentricity of the eccentric shaft 131, so that the driver 120 drives the crankshaft 130 to rotate, the eccentric shaft 131 on the crankshaft 130 drives the adapter 153 to move, and the adapter 153 drives the impeller 152 to rotate coaxially with the crankshaft 130, so as to realize the pressurized delivery of the gas in the suction housing 151 through the impeller 152.

[0039] Specifically, when the adapter 153 and the crankshaft 130 are connected, the first locking protrusion 1532a on the first connecting portion 1532 and the first locking groove 1311 on the eccentric shaft 131 can be locked to prevent the adapter 153 and the eccentric shaft 131 on the crankshaft 130 from relative movement.

[0044] It can be understood that the air inlet pipe 1514 is indirectly connected to the first air inlet 111 to prevent the vibration of the pump body from being transmitted to the housing 110 .

[0045] When the compressor 100 is working, the driver 120 is started, the driver 120 drives the crankshaft 130 to rotate, the eccentric shaft 131 on the crankshaft 130 drives the adapter 153 to move, and the adapter 153 drives the impeller 152 to rotate coaxially with the crankshaft 130, so that the gas from the first air inlet 111 is sucked into the intake housing 151 through the intake pipe 1514, and the gas in the intake housing 151 is pressed and sent to the cylinder 140 through the outlet pipe 1515 by the impeller 152 in the intake housing 151.

The piston rod 142 moves, and the piston rod 142 drives the piston member to perform reciprocating linear motion in the cylinder body 141, so that the gas compressed by the suction device 150 to the cylinder 140 is transmitted to the outside of the shell 110 through the cylinder 140 to achieve gas compression. The present application drives the cylinder 140 and the suction device 150 to move through the driver 120, and realizes the pressurized transmission of the gas outside the shell 110 to the cylinder 140 through the suction device 150, and then further pressurized and transported through the cylinder 140, and realizes double compression through the suction device 150 and the cylinder 140, thereby improving the compression efficiency of the compressor 100.

[0046] In a feasible embodiment of the present application, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the air intake housing 151 includes an upper cover body 1511 and a lower cover body 1512 , the second air inlet 1513 is arranged on the upper cover body 1511 , and the air outlet is arranged on the lower cover body 1512 .

[0047] Specifically, when assembling the compressor 100 of the present application, the driver 120, the crankshaft 130 and the cylinder 140 are first installed in the housing 110, and the driver 120, the crankshaft 130 and the cylinder 140 are connected by transmission.
