Abstract

The invention relates to the field of washing equipment and aims at providing a low-pressure maintaining high-pressure washing device. The low-pressure maintaining high-pressure washing device comprises a high-pressure pump which is provided with a motor. The low-pressure maintaining high-pressure washing device further comprises a low-pressure maintaining device. The low-pressure maintaining device comprises a valve body, a low-pressure maintaining valve and a control switch, wherein the valve body is provided with a pressure relief outlet, a high-pressure outlet and a high-pressure inlet communicating with an outlet hole of the high-pressure pump, the rear end of the low-pressure maintaining valve extends out of a valve rod at the rear end of the valve body, and the control switch is provided with a drive rod which is opposite to the rear end of the valve rod and is electrically connected with the motor. According to the low-pressure maintaining high-pressure washing device, when a high-pressure washing machine pauses, the high-pressure pump can achieve pressure maintaining with relatively low pressure, and no damage is caused.
