Description

Cleaning device

Technical Field

The present utility model relates to a cleaning device.

Background

An important component of the floor scrubber is the sewer sump. The sewage tank has the main function of collecting dirty water washed on the ground so as to be convenient for a user to pour. Therefore, it is necessary to detect whether the sewage tank is installed or not and whether the sewage tank is full of water after the installation.

The existing main technology for detecting whether the sewage tank is installed in place is through Hall switch detection or through two metal contacts. The Hall switch is simple in principle, a magnet is arranged in the sewage tank, and when the sewage tank approaches, a magnetic field is detected, namely, the sewage tank is judged to be arranged. For example, in the chinese patent application No. CN218635936U (application No. 202222176118.2), a water tank assembly and a water tank assembly mounting structure are disclosed, in which the water tank mounting structure uses a hall sensor and a magnet to realize the detection of whether the water tank is mounted in place. After the sewage tank is installed, the two metal electrodes on the machine body are conducted by the metal guide sheets on the sewage tank, namely, the sewage tank is judged to be installed. Such as the Chinese patent publication No. CN217659667U (202221054647.9), which discloses a sewage tank and a cleaning device, wherein the sewage tank and the structure adopting metal contacts are used for realizing the detection of the installation in place. And meanwhile, the detection of the water level reaching the set water level is realized by utilizing the metal contact.

The main technical drawbacks are evident for the above prior art means.

Firstly, in the Hall detection scheme, if the sensitivity is too high, the sewage tank is not mounted on the machine body, and the sewage tank is detected only when approaching; if the sensitivity is too low, the detection can be ensured after the sewage tank is assembled, but the structural size often has certain errors, especially when the floor washing machine with the sewage tank structure is applied, the whole machine moves when the floor washing machine works, the assembly gap between the sewage tank and the machine body can be enlarged, and the Hall detection signal can be lost. The sensitivity of the hall sensing scheme is therefore difficult to control.

The disadvantage of the contact scheme is more obvious, the contacts on the sewage tank and the machine body are in direct friction contact, and the sewage tank can be frequently disassembled and assembled, so that the contacts are worn after the sewage tank is used for a long time. Firstly, rust is generated, and the contact is not conducted; in addition, the contact is not achieved after the abrasion is serious, and the connection is gradually disconnected.

In addition, to simultaneously realize detection of three states of unfilled sewage tank, unfilled sewage tank in place and filled sewage tank in place, a plurality of sensors or a plurality of metal contacts are often required to be matched, the structure is relatively complex, and technical defects also exist.
