Title:
LIQUID STORAGE DEVICE AND CLEANING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/205998
Kind Code:
A1
Abstract:
A liquid storage device and a cleaning device. The liquid storage device comprises: a liquid storage structure (1), the liquid storage structure (1) being used for storing a liquid; a liquid inlet structure (2), wherein the liquid can flow into the liquid storage structure (1) through the liquid inlet structure (2); and a blocking structure (3), an inductive field generating part (4) for generating an inductive field, a sensing part (5), and an electric control part, wherein the blocking structure (3) is provided in the liquid storage structure (1); the sensing part (5) can sense the inductive field; the blocking structure (3) can float under the buoyancy of the liquid; the blocking structure (3) can block the sensing of the sensing part (5) for the inductive field when floating to a first liquid level; and the electric control part is used for controlling, when the blocking structure (3) blocks the sensing of the sensing part (5) for the inductive field, the liquid inlet structure (2) to stop inputting the liquid to the liquid storage structure (1). The cleaning device comprises the liquid storage device. When the liquid collected in the liquid storage device reaches a preset liquid level, the liquid storage device can stop the liquid from entering the liquid storage device, thereby avoiding the occurrence of accidents caused by overflow of the liquid storage device.
