The invention discloses a carpet cleaning machine with a pump pressure relief protection circuit. The carpet cleaning machine comprises a body, a pump, a water inlet pipe, a water outlet pipe and the pump pressure relief protection circuit, the pump is arranged in the body, the water inlet pipe and the water outlet pipe are connected with two ends of the pump respectively, the pump pressure relief protection circuit is connected with the pump and comprises a pressure relief valve, a pressure relief container and connecting pipes, the pressure relief valve is connected with the water outlet pipe and a pump tee, the pressure relief container is connected with the water inlet pipe and the pump tee, and the connecting pipes are connected with the pressure relief valve and the pressure relief container respectively. When a water channel is plugged or the pressure of the water channel is suddenly enlarged, water pressure acts to a valve spool of the pressure relief valve, a spring is compressed, so that sealing between a sealing gasket and a valve body is lost, and the pressure relief valve is opened, water flow moves towards a valve cover from the valve body, then the pressure relief container begins to store water until input of water in a water tank is stopped, normal water pressure difference between two ends of the pump is maintained, so that the pump is in a normal working state, and the service lives of the water channel and the pump are prolonged.
Description
technical field [0001] The invention relates to a carpet cleaning machine with a pump pressure relief protection circuit. Background technique [0002] When the existing carpet cleaners block the waterway or the waterway pressure suddenly increases, it is easy to make the pump in a high-pressure state, which will seriously damage the pump, affect the use of the product, and greatly shorten the life of the waterway and the pump. Contents of the invention [0003] The object of the present invention is to provide a carpet cleaning machine with a pump pressure relief protection circuit. [0004] A technical solution of the present invention is: a carpet cleaning machine with a pump pressure relief protection circuit, which includes a body, a pump arranged inside the body, water inlet and outlet pipes connected to both ends of the pump, and a pump connected to the pump A pressure relief protection circuit, wherein the pump pressure relief protection circuit includes a pressur...
