Specifically, as shown in fig. 3, the fan 16 and the sewage tank 15 are arranged in the front-rear direction. This can reduce the size of the main body 10 in the left-right direction, and make the shape of the main body 10 more suitable for the use habit of the user.

More specifically, as shown in fig. 3, the air inlet of the fan 16 is located at the upper end of the fan 16 and the air outlet is located at the lower end of the fan 16. This allows the fan 16 to be inverted to facilitate communication between the fan 16 and the waste tank 15.

Further, as shown in fig. 3, the inlet of the wastewater tank 15 is located at the lower end of the wastewater tank 15 and the outlet is located at the upper end of the wastewater tank 15. This facilitates communication of the waste tank 15 with the fan 16 and the interface 11.

Further, as shown in fig. 3, the interface 11 is located on the lower surface of the housing 18. This facilitates communication of the port 11 with the waste water tank 15.

Fig. 3 shows a cleaning device 1 according to some examples of the invention. As shown in fig. 3, the sewage tank 15 is connected to the fan 16 through a duct 17. Therefore, the communication between the fan 16 and the sewage tank 15 is convenient, and the flexibility of position selection of the fan 16 and the sewage tank 15 is improved.

Specifically, the fan 16 may be located near the center of the foul water tank 15 in the up-down direction. This allows the height of the fan 16 to be reduced, thereby lowering the overall center of the airframe 10, while facilitating the placement of structure beneath the fan 16.

A three-way valve 100 may be provided below the fan 16. This can improve the space utilization, further facilitating the reduction in the overall size and height of the body 10.

Specifically, as shown in fig. 3, the air duct 17 includes a vertical sewage tank section, a vertical fan section, and a connecting section, the lower end of the vertical sewage tank section is connected to the upper end of the sewage tank 15, the lower end of the vertical fan section is connected to the upper end of the fan 16, and the connecting section is connected to the vertical sewage tank section and the vertical fan section, respectively. This facilitates the manufacture and installation of the air guide duct 17.

Optionally, as shown in fig. 3, the upper end of the vertical fan section is lower than the vertical sewage tank section. Therefore, the fan 16 with a lower connecting position can be conveniently connected, the space occupied by the air guide pipe 17 can be reduced, and the space in the shell 18 can be fully utilized.

More specifically, as shown in fig. 3, the connection section extends from the vertical section of the waste water tank to the vertical section of the fan in a downward inclination manner. Therefore, the connection between the vertical section of the sewage tank and the vertical section of the fan can be facilitated.

Advantageously, an air filter is connected between the waste tank 15 and the air duct 17. Therefore, impurities in the air can be filtered by the air filter before the air enters the air guide pipe 17 and the fan 16, and the phenomenon that the impurities enter the fan 16 to influence the operation of the fan 16 is avoided.

Figures 1-3 illustrate a body of a cleaning device according to some examples of the invention. As shown in fig. 1-3, the interface 11 is adapted to be detachably connected to a floor brush 21 of the cleaning device 1. Thus, the body 10 can be detached from the floor brush 21 to allow the body 10 to be placed alone.

In particular, the interface 11 is adapted to be selectively detachably connectable with a floor brush 21 of the cleaning device 1 or with an air suction duct of the cleaning device. This enables the body 10 to switch between the functions of cleaning with the floor brush 21 and cleaning with the air intake duct, thereby expanding the use scene of the body 10.

Specifically, as shown in fig. 1 to 3, the cleaning apparatus 1 is an upright type cleaning apparatus. This allows the body 10 to be applied to an upright type cleaning apparatus.

It will be appreciated by those skilled in the art that cleaning devices such as sweeping robots do not present the problem of being prone to tipping themselves.

Optionally, the ratio of the height of the housing 18 to the dimension in the front-to-rear direction is 2-2.5. This allows the fuselage 10 to have a reasonable shape, avoiding the tendency to topple over at too high a height.

Other configurations and operations of the cleaning apparatus 1 according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail herein.
