The dust collecting box 400 can effectively prevent dust from flying to cause secondary pollution in the process of cleaning and filtering, and meanwhile, the dust collecting box 400 can effectively prevent the dust from being discharged to the indoor environment or the outdoor environment to cause environmental pollution.

Optionally, the filter screen 200 includes a frame 210 and a filter screen, the frame 210 includes a first frame and a second frame, the first frame is disposed opposite to the second frame, the first frame is configured with a first folded edge 211 towards the accommodating space, the second frame is configured with a second folded edge 212 towards the accommodating space, and a side surface of the second folded edge 212 towards the first folded edge 211 is configured with a sliding rail 213; a screen disposed on the frame 210; wherein, the dust collection device 300 is slidingly connected to the sliding rail 213.

The filter screen 200 comprises a frame 210 and a filter screen, wherein the frame 210 is arranged at the air outlet 411, and the filter screen is arranged on the frame 210. By adopting the arrangement form, on one hand, the filter screen is convenient to install and fix; on the other hand, the frame 210 can effectively prevent the filter screen from being deformed, thereby effectively ensuring the filtering effect of the filter screen 200 on the air flowing through the air inlet.

The frame 210 includes a first frame and a second frame, and the first frame and the second frame are disposed opposite to each other. The first frame and the second frame respectively form a first folded edge 211 and a second folded edge 212 in a direction facing the accommodating space inside the housing 100, and a sliding rail 213 is formed on a side surface of the second folded edge 212 facing the first folded edge 211. With such arrangement, the first flange 211 and the second flange 212 together define an installation space, thereby facilitating installation and arrangement of the dust suction device 300.

Meanwhile, by providing the second flange 212, the slide rail 213 is configured at the second flange 212. Thus, the sliding rail 213 is convenient to set, and the overall structural strength of the frame 210 can be improved, so that the bearing capacity of the frame 210 is ensured, and the service life of the filter screen 200 is effectively prolonged.

The dust collection device 300 is connected with the sliding rail 213 in a sliding way, and dust on the filter screen 200 is cleaned in an omnibearing way by moving the dust collection device 300 along the sliding rail 213. With such arrangement, the comprehensiveness and cleaning effect of cleaning the filter screen 200 can be effectively improved.

In the embodiment of the disclosure, the first frame and the second frame may be two frames perpendicular to the ground in the use state, or may be two frames parallel to the ground in the use state, which is not limited specifically.

Thus, the air at the suction nozzle 310 is flowed by the driving of the blower fan, and flows from the suction nozzle 310 to the dust box 400 through the air inlet hose 320. Dust on the filter screen 200 enters the dust box 400 through the air inlet hose 320 by the wind suction force.

With this arrangement, the air is driven by the fan to flow to suck the dust on the filter screen 200 into the dust box 400. Dust on the filter screen 200 can only enter the suction nozzle 310 along the air flow direction under the action of wind suction force, and the dust can not fly to the surrounding environment. So that the secondary pollution caused by the flying of the dust can be effectively prevented, and at the same time, the dust is collected by the dust collecting box 400 to effectively prevent the dust from being discharged to the indoor environment or the outdoor environment, thereby causing the environmental pollution.

By arranging the driving component 330 to be in driving connection with the suction nozzle 310, the driving component 330 drives the suction nozzle 310 to move along the sliding rail 213, so that the comprehensiveness and cleaning effect of cleaning the filter screen 200 can be effectively improved. Meanwhile, the mode of driving the suction nozzle 310 to move by the driving assembly 330 is set to replace the manual movement mode, so that the convenience of cleaning the filter screen 200 can be effectively improved, and the use experience of a user is improved.
