As shown in fig. 1 and 2, in any of the above embodiments, the housing 102 includes a main housing 1024, an upper housing 1022, and a lower housing 1026. The main housing 1024 has a cylindrical shape, the upper housing 1022 is fastened to the front end of the main housing 1024, and the connector 130 is mounted on the main housing 1024. The lower shell 1026 is fastened to the lower end of the main shell 1024, and the main shell 1024, the upper shell 1022, and the lower shell 1026 collectively enclose a space for accommodating the compression assembly 110 and the drive assembly 120.

Compression assembly 110 includes an upper bearing 111, an exhaust pipe 112, an upper cylinder 113, a partition 114, a lower cylinder 115, a piston 116, a lower bearing 117, a slide 118, and a crankshaft 119. Upper bearing 111 and lower bearing 117 are used to position crankshaft 119, and when drive assembly 120 drives crankshaft 119 in rotation, crankshaft 119 drives reciprocating motion to output compressed medium from exhaust pipe 112 to a target area.

The driving assembly 120 includes a rotor disc cover 122, a rotor 124 and a stator 126, wherein the rotor disc cover 122 is used for fixing the rotor 124, the rotor 124 rotates under the action of electromagnetic field after the stator 126 is electrified, and the rotating rotor 124 drives the crankshaft 119 to synchronously rotate so as to realize driving of the compression assembly 110.

The compressor 100 further includes an oil line member 160 and a reservoir 170, the reservoir 170 for storing a medium to be delivered in a cable, the oil line member 160 for delivering the medium in the reservoir 170 to the compression assembly 110.
