Pump

Abstract

The invention relates to the field of adjustment, in particular to a pump with good heat dissipation performance, which comprises a shell and a first motor, the pump comprises a first cavity, a first opening and a second opening corresponding to the shell, at least part of the first motor is located in the first cavity, the first opening is communicated with the first cavity, and the pump comprises a pipeline assembly and an extrusion part located in the first cavity; at least part of the pipeline assembly is located in the first cavity, the pipeline assembly at least comprises a first port and a second port, the first port is communicated with the first cavity, and the second port is communicated with the second port; the pipeline assembly comprises a first part, the first part is a hose and at least provided with a first part and a second part, at least part of the extrusion part abuts against the first part, the flow area corresponding to the first part is smaller than that of the second part, and at least part of the extrusion part can move relative to the first part. The movement path corresponding to the extrusion part is at least partially in the extending direction of the first part, liquid enters the first cavity to take away heat in time, and the heat dissipation performance of the pump is improved.
