The embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 1 to 4, the embodiment of the present application discloses a cleaning apparatus including a body 500, a fan assembly 300, a filter assembly 400, and a sump 100.

Wherein, the blower assembly 300 and the sewage tank 100 are both installed on the body 500. Alternatively, the fan assembly 300 may be mounted inside the fuselage 500; the sewage tank 100 may be installed inside the body 500, and of course, a portion of the sewage tank may be located inside the body 500 and a portion of the sewage tank may be located outside the body 500 to facilitate the disassembly of the sewage tank 100.

The fan assembly 300 is connected to the waste water tank 100, and the filtering assembly 400 is disposed between the fan assembly 300 and the waste water tank 100 for filtering the air sucked into the fan assembly 300. Optionally, the fan assembly 300 has an air inlet to communicate the air inlet with the waste water tank 100, for example, the air inlet is connected with the waste water tank 100 through a pipe to achieve communication.

Thus, when the fan assembly 300 is started, the air in the sewage tank 100 can be sucked into the fan assembly 300 and discharged, and in the process, the air passes through the filtering assembly 400, so that the air is filtered by the filtering assembly 400, and further, odor and the like in the air can be filtered by the filtering assembly 400, so that the odor in the sewage tank 100 is prevented from being discharged to the surrounding environment by the fan assembly 300 to influence the quality of the surrounding air.

Considering that the sewage has oil stains therein, when the sewage is collected in the sewage tank 100, the water stains and the oil stains in the sewage are easily adhered to the inner wall of the sewage tank 100 and are not easily separated. Based on this, the inner wall of the sewage tank 100 is provided with the hydrophobic and oil-repellent layer 120, and the hydrophobic and oil-repellent layer 120 has good waterproof, hydrophobic, oil-proof and oil-repellent functions, so that water stains and oil stains are not easy to adhere, and dirt can be prevented from adhering to the inner wall of the sewage tank 100.
