As shown in fig. 1 to 5, the cleaning machine in the present embodiment includes a machine body 1 and a water tank 2 detachably attached to the machine body 1. The water tank 2 may be a clean water tank 2 or a sewage tank 2. There is sewage in the sewage tank 2, if the water level information transmission scheme is realized through the contact structure in the prior art, the condition of pollution detection contact appears more easily, so the following technical scheme in this embodiment is more applicable to in the sewage tank 2, can avoid the condition that the contact leads to unable normal work to the maximum extent.

The water tank 2 comprises a tank body 21 and a tank cover 22, the machine body 1 is provided with a tank position matched with the water tank 2 in a clamping manner, the tank cover 22 and the tank body 21 can be clamped on the tank position of the machine body 1 after being buckled, and then the part of the water tank 2 faces the machine body 1.

Two water level detection electrodes 3 are arranged in the water tank 2 at intervals, specifically, the two water level detection electrodes 3 are arranged on the tank cover 22, the upper end of the water level detection electrode 3 is positioned in the tank cover 22, and the water level detection electrode 3 penetrates downwards from the tank cover 22 and extends to a water level alarm position in the tank body 21. When the water level in the tank 21 reaches the set alarm water level, the water in the tank 21 conducts the two electrodes. In order to avoid the pollution to the water level detection sheet as much as possible, the service life of the water level detection sheet is prolonged, the water level detection sheet is wrapped with a shell, the lower end of the shell is opened, and then the lower end of the water level detection sheet is exposed out of the shell to realize the detection of the water level in the box 21.
