This utility model discloses a tank-type stacked pressure-free variable frequency secondary water supply device, relating to the technical field of water supply equipment. It includes a flow stabilizing tank, a pump assembly, a pressure stabilizing tank, and a detection assembly. The flow stabilizing tank is connected to the equipment's inlet pipe. The pump assembly is connected to the outlet pipe of the flow stabilizing tank and includes multiple pump units, each independently frequency-controlled, pumping water to the outlet pipe. The pressure stabilizing tank is connected to the outlet pipe and used to balance water pressure fluctuations. The pressure stabilizing tank includes a shell and multiple air chambers, each with a different internal pressure. The detection assembly, located on the outlet pipe, includes a pressure sensor and a pressure switch. The pressure sensor detects water pressure changes on the outlet pipe, and the pressure switch controls the start and stop of the pump units. The technical solution provided by this utility model aims to solve the problem of insufficient capacity of traditional large-capacity single-chamber tanks to cope with high-frequency pressure fluctuations, ensuring a stable water supply.

And the purposes of energy conservation and environmental protection are achieved.

This application discloses a control method for a surface cleaning device. The surface cleaning device includes a floor brush with cleaning components and a suction system for removing dirt. The floor brush includes a housing, on which are a movable front scraper located in front of the cleaning components and a floor scraper located behind the cleaning components and in contact with the ground. When the floor brush moves forward, the front scraper moves upward away from the ground; when the floor brush moves backward, the front scraper moves downward and in contact with the ground. The method includes reducing the operating power of the suction system when the floor brush moves backward. In this application, when the floor brush moves backward, the front scraper contacts the ground, and together with the floor scraper in contact with the ground, the brush chamber and the ground form a relatively sealed space. Under the action of the front scraper, the floor scraper, and the suction airflow of the suction system, the resistance of the floor brush to the ground increases. At this time, reducing the operating power of the suction system can ensure the dirt removal effect of the surface cleaning device and reduce the operating resistance of the floor brush to the ground, thus ensuring the cleaning effect.
