Document Type and Number:
WIPO Patent Application WO/2022/001339
Kind Code:
A1
Abstract:
A device for directly detecting a state of a water tank (1) by means of an electrical signal, a method for detecting a state of a water tank (1), and a floor cleaning machine. Said device comprises a water tank (1) and a detection device (2) connected to the water tank (1); the detection device (2) is located inside the water tank (1), and the detection device (2) comprises a first electrically conductive contact body (21), a second electrically conductive contact body (22), and a microprocessor (23); the first electrically conductive contact body (21) is located at the bottom of the water tank (1) and is connected to the bottom of the water tank (1); the second electrically conductive contact body (22) is located at an upper end of the water tank (1), is connected to a side wall of the water tank (1) and is located at the highest water level of the water tank (1); when the water tank (1) is mounted in place, the first electrically conductive contact body (21) and the second electrically conductive contact body (22) are electrically connected to the microprocessor (23) respectively. The device for directly detecting a state of a water tank (1) by means of an electrical signal has a simple structure, is convenient to mount, has low requirements for the structure of the water tank (1), has a wide range of application, has a high measurement precision, and is not affected by impurities in water.
