Referring to fig. 1 to 3, an embodiment of the present application provides a recycling assembly 40 including a recycling bin 41, a water full detection sensor 42, and an early warning device.

Referring to fig. 2 to 4, a recycling tank 41 is provided for containing recycled liquid. The recovery tank 41 has a liquid inlet 411, a recovery tank air duct 412 communicating with the liquid inlet 411, and a collection chamber 413 located outside the recovery tank air duct 412 and separated from the recovery tank air duct 412. The liquid inlet 411 is located at the bottom of the recovery tank 41, and the recovery tank air duct 412 is located downstream of the liquid inlet 411 and is used for conveying the recovered liquid. The recovered liquid enters the recovery tank 41 from the liquid inlet 411, passes through the recovery tank air channel 412, and falls into the collection chamber 413 for storage.

The full water detection sensor 42 is disposed in the recovery tank 41, and when the full water detection sensor 42 is in a liquid environment, the full water detection sensor 42 outputs a first signal, and when the full water detection sensor 42 is in an air environment, the full water detection sensor 42 outputs a second signal.

And the early warning device is electrically connected with the full water detection sensor 42 and receives the first signal and responds to the first signal to send out an early warning signal so as to warn that the liquid in the recovery box body 41 reaches a warning height.

Referring to fig. 2 to 3, the recovery tank air duct 412 includes a first end 414 close to the liquid inlet 411 and a second end 415 opposite to the first end 414, the second end 415 is higher than the first end 414 in the water level ascending and descending direction, and the water level detection sensor 42 is lower than the second end 415. Referring to fig. 7 and 8, the water full detection sensor 42 includes a light emitting unit 421, a light receiving unit 422, and a reflecting structure (423, 424) for reflecting light signals, and by setting the reflecting structure (423, 424) of the water full detection sensor 42 lower than the second end 415, when the liquid level of the liquid collected in the collection cavity 413 does not reach the second end 415, the early warning device will send out an early warning signal to prevent the liquid level from reaching the second end 415, which causes the sewage to flow back to the ground from the recovery tank air duct 412, which causes secondary pollution, and can prevent the sewage from being sucked into the motor and the machine after being over full.

The warning height may be a specific threshold, such as two-thirds of the height of the collection chamber 413, or a height range within the collection chamber 413 that is five centimeters lower than the second end 415, and so on, and the specific setting may be defined reasonably according to the actual volume of the product. In another embodiment, the warning height may refer to a mounting height of the full water level sensor 42, and since the full water level sensor 42 is mounted in the recycling bin 41, the warning height may be indirectly determined as long as the mounting height of the full water level sensor 42 is determined, and the full water level sensor 42 may be mounted at a higher position without affecting the cleaning performance, so as to ensure that the recycling bin 41 can collect as much liquid as possible at a single time, and reduce the number of times that a user dumps the liquid or cleans the recycling bin 41.
