When the device is used, after the water pump 23 is started, the motor in the water pump 23 drives the impeller to start rotating, the high-speed rotation of the impeller forms a low-pressure area (also known as a vacuum area) at the center of the impeller, and the pressure of the low-pressure area is lower than the atmospheric pressure. Due to the pressure difference between the low-pressure area and the outside atmosphere, the liquid (such as water) is sucked into the pump body under the action of the outside atmospheric pressure. When draining, the sucked liquid is pushed to the outlet of the pump shell under the action of the impeller with the continuous rotation of the impeller. In this process, the kinetic energy of the liquid gradually increases, and the pressure also gradually increases, and when the liquid is compressed to a certain pressure, it will be discharged from the pump body, effectively improving the convenience of the device
