Title:
WATER DISTRIBUTION STRUCTURE, WATER TANK STRUCTURE, AND CLEANING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/123855
Kind Code:
A1
Abstract:
A water distribution structure, a water tank structure, and a cleaning device. The water distribution structure comprises a suction source (1300), a water distributor (1400), and a first one-way valve (1430). The suction source (1300) is configured to be connected to a water supply tank (1200); the water distributor (1400) comprises a first distribution pipeline (1410) and a second distribution pipeline (1420); the first distribution pipeline (1410) and the second distribution pipeline (1420) are connected to the suction source (1300), the first one-way valve (1430) is connected between the suction source (1300) and the water distributor (1400), and the first one-way valve (1430) can be communicated with the suction source (1300) and the water distributor (1400) under a pressure value formed when the suction source (1300) is started. In the water distribution structure, the water tank structure, and the cleaning device, when there is residual water in a pipeline between the first one-way valve (1430) and the water distributor (1400), the first one-way valve (1430) can prevent water from the water supply tank (1200) from being conveyed downstream; at this time, the end having water therein in the pipeline at the downstream of the first one-way valve (1430) is sealed, one end of the water distributor (1400) is communicated with air, and under the action of atmospheric pressure, a sealing effect of the first one-way valve (1430) can enable the water in the pipeline located between the first one-way valve (1430) and the water distributor (1400) to not flow out of a main unit, thereby solving the problem of water leakage and ensuring the cleanness of the ground.
