Hand-held electric cleaning device

Abstract

The invention relates to a hand-held electric washer, which comprises a motor, a high-pressure pump, a spray gun and a control switch, wherein a plunger is arranged inside a pump body of the high-pressure pump; a water inlet valve is arranged inside a plunger hole; a pump head is provided with a water inlet A, a water outlet A and a water return opening; the water inlet A is communicated with a water inlet seat through the water inlet valve; the water inlet seat is provided with a water inlet B and a water outlet B; the water inlet B is connected with a water source; the water outlet B is communicated with the water inlet A and the water return opening; the water outlet A is communicated with the water outlet seat through a water outlet valve; and a water outlet seat is communicated with the water return opening. The hand-held electric washer is characterized in that the motor, the high-pressure pump, the spray gun and the control switch are arranged inside the same gun shell; the control switch comprises a high-pressure trigger and a low-pressure trigger; the high-pressure trigger is provided with a transmission shaft and connected with a water pause switch box of which the inside is provided with a sensitive switch control motor, and the inside of the high-pressure trigger is provided with an axle hole; the inside of the axle hole is provided with a rotating shaft which contacts a mandril; a gun valve is arranged below the mandril and on an opening A of a tee joint and communicated with the water outlet seat through a check valve; an opening C of the tee joint is connected with a high-pressure spray head through a high-pressure hose, a gun barrel connecting seat and a gun barrel; the high-pressure trigger is provided with a handle; and the low-pressure trigger controls a low-pressure spray head.

Description

technical field [0001] The invention relates to a cleaning machine, in particular to a hand-held electric cleaning machine, which is mainly used for cleaning cars, glass doors and windows, garden roads, livestock farms and the like. Background technique [0002] The appearance of electric cleaning machine brings great convenience to people's life, and it can be used for cleaning as automobile, glass doors and windows, courtyard road etc., not only efficient but also safe and convenient. The electric washing machine is mainly composed of a motor, a high-pressure pump, a spray gun and a control part. The existing electric washing machines are heavy in weight, so the motor, high-pressure pump, and control part are generally assembled into one body and placed fixedly, and the spray gun is moved to work. The disadvantages of this form are: first, the structure is complicated and the volume is large; Second, the cost is high; third, it is inconvenient to shut down when a fault oc...

Problems solved by technology

The existing electric washing machines are heavy in weight, so the motor, high-pressure pump, and control part are generally assembled into one body and placed fixedly, and the spray gun is moved to work. The disadvantages of this form are: first, the structure is complicated and the volume is large; Second, the cost is high; third, it is inconvenient to shut down when a fault occurs; fourth, the nozzle needs to be replaced when spraying cleaning fluid and low-pressure cleaning, which is troublesome to operate; fifth, the pressure is used to control the motor and the unloading valve at the same time during the cleaning process. The control pressure is high, which affects the life of the washing machine
