The filter 25 is provided with a fixing groove 26; the vibration motor 27 is embedded in the fixing groove 26. The filter 25 of the filter module 24 filters and isolates dust and foreign matter, so that dust and foreign matter fall into the dust box 6, and can also prevent dust and foreign matter from entering the fan 9 and causing blockage; when the filter 25 is blocked, the vibration motor 27 works to vibrate the dust and foreign matter on the filter 25 and drop it, so that the cleaning is completed in time and the work continues. The filter 25 is elastically connected to the housing 1 through the elastic member, which can play a role in shock absorption. When the vibration motor is working, the garbage on the filter 25 can be automatically shaken off. It avoids the decrease of suction force and the influence of dust collection effect due to the blockage of the filter module during the cleaning process.

[0080] Specifically, the filter element 25 includes a fixed grille and filter cotton, and the fixed grille is elastically connected to the housing 1 through the elastic member, so as to facilitate the disassembly, assembly and replacement of the filter cotton. Specifically, a motor cover 28 is provided on the vibration motor 27. In addition, as an alternative embodiment, the vibration motor 27 can be omitted, and a blowing component can also be provided on the filter element 25 to blow air through the filter element 25 toward the inside of the dust box 6.

A rotating drive mechanism 33 is provided on the roller brush 32, and the rotating drive mechanism 33 drives the roller brush 32 to rotate. During the cleaning process, the rotating drive mechanism 33 drives the roller brush 32 to rotate, brush the surface to be cleaned, and make the dust and foreign matter on the surface to be cleaned fall off. The fan 9 sucks the air duct, so that a negative pressure chamber is formed between the groove 30 at the bottom of the housing 1 and the surface to be cleaned, and the dust and foreign matter are sucked into the air duct through the groove 30, and the dust and foreign matter enter the dust box 6 through the first channel enclosed by the first flange 31.

The moving block 38 slides along the opening of the guide groove 36 so that the latch 37 is inserted into the limiting hole 35, so that the dust box 6 and the housing 1 are hingedly connected, and the dust box 6 can be turned around the latch 37 as an axis. When the dust box 6 needs to be disassembled, the moving block 38 is moved in a direction away from the limiting hole 35 so that the latch 37 is disengaged from the limiting hole 35, so as to facilitate the disassembly and assembly of the dust box 6. Specifically, a fastener 39 is provided on the moving block 38, and the fastener 39 is locked to limit the sliding of the latch 37 in the guide groove 36. In addition, as an alternative embodiment, the dust box 6 and the housing 1 can also be connected in other ways such as hinges.

Through the in-place sensor 41 on the outer wall of the shell 1, it is possible to monitor whether the dust box 6 is closed in place, so as to feed back a signal to the controller to control the start and stop of the flip drive assembly 8. Specifically, the in-place sensor 41 can be a travel switch, a pressure sensor, a photosensitive sensor, etc. In addition, as an alternative embodiment, the in-place sensor 41 can also be provided at the bottom of the mounting groove 5, and in the closed state, the second side of the fan-shaped structure of the dust box 6 contacts the in-place sensor 41.

[0086] It is necessary to add that, if Figure 1 , Figure 6 , Figure 8 As shown, the shell 1 includes three parts: an upper shell 2, a lower shell 3 and a cover 4. The upper shell is used to install the dust box 6, the filter module 24, the flip drive assembly 8 and the rotation drive mechanism 33. The cover 4 is arranged on the top of the upper shell 2, and the lower shell 3 is used to install the roller brush 32.

When it is necessary to dump the dust and foreign matter, the flip drive component 8 drives the dust box 6 to flip outward toward the outside of the mounting groove 5, and the discharge port 7 of the dust box 6 faces below the horizontal plane and is located outside the mounting groove 5, so that the dust and foreign matter are dumped out from the discharge port 7 of the dust box 6. After the garbage dumping is completed, the flip drive component 8 drives the dust box 6 to reset. Automatic dumping of dust and foreign matter in the dust box 6 is achieved.

[0090] In addition, if Fig.10As shown, this embodiment also provides a photovoltaic cleaning robot, including a body 42 and a cleaning mechanism described in the above embodiment, wherein the cleaning mechanism is detachably mounted on the body 42. The body 42 carries the cleaning mechanism to walk on the surface to be cleaned for cleaning, and when the dust box 6 is full, the cleaning robot moves to the dumping position to dump the dust box 6.
