Title:
CLEANING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/272888
Kind Code:
A1
Abstract:
A cleaning apparatus, comprising a machine body (100), and a control module (200) and a waste water tank (300) that are arranged on the machine body (100). The machine body (100) is provided with a first conductive member (410) and a second conductive member (420), which are electrically connected to the control module (200); and the waste water tank (300) is provided with a third conductive member (510) for coming into contact the first conductive member (410), a fourth conductive member (520) for coming into contact the second conductive member (420), a first water level sensing member (610) electrically connected to the third conductive member (510), and a second water level sensing member (620) electrically connected to the fourth conductive member (520), wherein a sensing end of the first water level sensing member (610) and a sensing end of the second water level sensing member (620) are both located in the waste water tank (300). When the water level in the waste water tank (300) reaches the sensing ends of the first and second water level sensing members (610, 620), a first loop signal is formed among the first, second, third and fourth conductive members (410, 420, 510, 520), such that the control module (200) can determine the water level in the waste water tank (300) on the basis of the first loop signal.
