Handheld portable cleaning machine with dual-liquid-cooling pump

Abstract

The invention discloses a handheld portable cleaning machine with a dual-liquid-cooling pump. The handheld portable cleaning machine with the dual-liquid-cooling pump comprises the pump and a shell. The pump is driven by a motor and comprises a pump water inlet and a high-pressure water outlet. The shell wraps the pump and the motor in a sealing mode. The pump comprises at least one plunger, an inclined disc and a pump case. The inclined disc is driven by the motor to drive the plungers to move along the straight line. The pump case comprises a sealed cavity. The sealed cavity holds the plungers, the inclined disc and a lubricating cooling agent. The pump case comprises at least one cooling channel, a water inlet and a water outlet. The water inlet communicates with one end of each coolingchannel, and the water outlet communicates with the other end of each cooling channel. The water inlet is connected with an external water source, and the water outlet is connected with the pump water inlet. The handheld portable cleaning machine with the dual-liquid-cooling pump has the beneficial effects that the cooling conducted by flowing water located outside the pump is additionally arranged as the cooling conducted by the cooling agent located inside the pump, dual liquid cooling with the features of inside and outside combination and circulation and non-circulation combination is achieved, and therefore the pump body cooling problem can be thoroughly solved, and the service life of the pump is greatly prolonged. In addition, the situation that a human body is scalded in the usingprocess is avoided, and the handheld portable cleaning machine with the dual-liquid-cooling pump is safer in the using process.

Description
