The cleaning head 200 is used to contact with a floor surface to be cleaned for cleaning.

The main machine of the cleaning device 100 comprises a machine body 1, a clean water tank 2, a sewage tank 3, a suction component 4 and a water shortage detection component, wherein the clean water tank 2 is used for storing clean water or cleaning fluid, the sewage tank 3 is used for storing dirt, the suction component 4 is used for sucking the dirt on the surface to be cleaned into the sewage tank 3, and the water shortage detection component is used for detecting the liquid level in the clean water tank 2. The clean water tank 2, the sewage tank 3 and the suction assembly 4 are arranged on the machine body 1.

As shown in fig. 4 to 7, the water shortage detection module includes a first detection terminal 51 and a second detection terminal 52, the first detection terminal 51 and the second detection terminal 52 are connected to or disconnected from each other based on the liquid level inside the fresh water tank 2, the first detection terminal 51 has a first inner end 511 and a first outer end 512, the second detection terminal 52 has a second inner end 521 and a second outer end 522, the first inner end 511 and the second inner end 521 are exposed to the inside of the fresh water tank 2, and the first outer end 512 and the second outer end 522 protrude outside the fresh water tank 2. The first inner end 511 and the second inner end 521 exposed to the inside of the fresh water tank 2 means that the first inner end 511 and the second inner end 521 can come into contact with the liquid stored in the fresh water tank 2. The first outer end 512 and the second outer end 522 extending out of the water purifying tank 2 may be connected to other electronic parts by wires, which can determine whether the first detecting terminal 51 and the second detecting terminal 52 are connected or disconnected, and further determine to perform the next operation, such as giving an alarm.

When the liquid level in the fresh water tank 2 is above the water shortage level, i.e., the fresh water tank 2 is not short of water, both the first inner end 511 and the second inner end 521 can be brought into contact with the liquid, and the first detection terminal 51 and the second detection terminal 52 are conducted to each other due to the conductivity of the liquid. When the liquid level in the fresh water tank 2 is below the water shortage level, that is, the fresh water tank 2 has reached the water shortage state, at least one of the first inner end 511 and the second inner end 521 is completely exposed above the liquid level, and at this time, the first detection terminal 51 and the second detection terminal 52 are disconnected because there is no liquid passing through between the first inner end 511 and the second inner end 521. Thus, the first detection terminal 51 and the second detection terminal 52 can be turned on or off from each other based on the liquid level inside the fresh water tank 2.
