Specifically, as shown in fig. 2, the water tank of the present invention includes a base 600 and a water tank body 500 placed on the base 600. When water is changed, the water tank body 500 needs to be taken down from the base 600 and put back after being filled with clean water, and if the water tank body 500 is not correctly placed on the base 600, the normal use of the cleaning device is affected, so that the in-place situation of the water tank body 500 needs to be detected in real time. As shown in fig. 1, the in-place detection device of the water tank of the present invention includes an infrared transmitter 100, an infrared receiver 200 and an infrared reflection structure 300. Wherein, the infrared emitter 100 is fixed on the base 600 and emits infrared light to the outer wall 510 of the water tank body 500; the infrared receiver 200 is fixed on the base 600 and disposed toward the outer wall 510 to receive infrared light; the infrared reflection structure 300 is fixed on the outer wall 510 and is disposed corresponding to the infrared emitter 100 and the infrared receiver 200, so as to transmit the infrared light emitted from the infrared emitter 100 to the infrared receiver 200 when the water tank body 500 is correctly placed on the base 600. And when water tank body 500 is incorrectly placed on base 600, the infrared light emitted by infrared emitter 100 is scattered and cannot be received by infrared receiver 200, so that whether infrared receiver 200 receives infrared light or not can be accurately judged by judging whether water tank body 500 is correctly placed on base 600 or not.
The infrared reflection structure 300 arranged on the water tank body 500 guides infrared light, when the water tank body 500 is in place, namely the water tank body 500 is correctly placed on the base 600, the infrared light reflected and transmitted to the infrared receiver 200 by the infrared reflection structure 300 has less loss and less light intensity reduction; when the water tank body 500 is not in place, that is, the water tank body 500 is detached or not properly placed on the base 600, the infrared light is scattered and cannot return to the infrared light receiver 200, and the infrared light transmitted to the infrared light receiver 200 approaches zero. Therefore, whether the water tank is in place or not can be judged by detecting the intensity of the infrared light received by the infrared receiver 200, the structure is simple, the production cost is low, and the application prospect is wider.

Thus, the infrared receiver 200 can receive infrared light only when the water tank body 500 is properly placed on the base 600, that is, the water tank is in place, and the intensity of infrared light received by the infrared receiver 200 is zero when the water tank body 500 is disassembled for water exchange or the water tank body 500 is not properly placed on the base 600.
