[0062] After cleaning, the fan 32 works to pump external air into the heating chamber 31, and the electric heating wire 34 and the metal rod 33 heat the air. Then, the control valve 36 is opened, so that the hot air is sprayed toward the components through the heating tube 35 and the drying plate 37 to dry the components, thus realizing the drying function. The third electric telescopic rod 41 is shortened to drive the sealing plate 42 to move, and the sealing plate 42 is separated from the sealing groove 39, thereby opening the control valve 36 to facilitate air circulation.

[0063] When detecting the amount of water inside the cleaning box 17, the signal transmitter 45 transmits a signal, the signal receiver 46 receives the signal, the floating block 48 rises and falls with the liquid level, driving the reflecting plate 49 to rise and fall, and the reflecting plate 49 reflects the signal. The amount of water can be judged according to the length of the signal reflection time, thereby realizing the detection function. When detecting the content of waste liquid, the floating plate 52 floats with the liquid level. When the waste liquid is relatively large, the floating plate 52 drives the lifting rod 51 to rise, and the first spring 53 contracts, so that the conductive block 54 contacts the conductive rod 55, and the third water pump 61 is controlled to start working to pump out the waste liquid, thereby realizing the detection function.

[0064] When the warning is given, the warning light 57 and the buzzer 58 work to warn the surrounding staff.
