Specifically, the lifting assembly 30 includes a lifting member 31 and a push rod motor 32, and the lifting member 31 is connected to the cleaning assembly 10. The pulling member 31 may be a wire rope, a pull rod, etc., and is not limited thereto. The push rod motor 32 may drive the cleaning assembly 10 via the pull member 31. In the event that it is desired to lift the cleaning assembly 10, the pusher motor 32 is operated to lift the cleaning assembly 10 by the pull member 31 to separate the first cleaning portion 12 from the surface to be cleaned. In the event that the cleaning assembly 10 is to be lowered, the pusher motor 32 lowers the cleaning assembly 10 via the pull member 31 so that the first cleaning portion 12 engages the surface to be cleaned.

Referring to fig. 2 to 4, the cleaning assembly 10 includes a supporting portion 11, a first cleaning portion 12, a second cleaning portion 13, a first driving portion 14 and a second driving portion 15. The support portion 11 includes a bracket 111 and a plurality of supporting members 112, and the plurality of supporting members 112 are connected to the bracket 111. The first cleaning part 12 is disposed around the plurality of supporting members 112 and the bracket 111, and the first cleaning part 12 is supported by the plurality of supporting members 112 and the bracket 111 and is expanded in a polyhedral shape. The second cleaning portion 13 is attached to the bracket 111, the second cleaning portion 13 being in contact with the first cleaning portion 12, the second cleaning portion 13 also being in contact with the surface to be cleaned to clean the surface to be cleaned. The first driving part 14 is connected to the supporting part 11, and the first driving part 14 is used for driving the first cleaning part 12 to roll relative to the supporting part 112. The second driving part 15 is connected to the supporting part 11, the second driving part 15 is used for driving the second cleaning part 13 to roll, and the second cleaning part 13 can rub against the first cleaning part 12 when rolling to clean the first cleaning part 12.

Referring to fig. 5 and 8, the cleaning assembly 10 uses the bracket 111 and the supporting member 112 to support the first cleaning portion 12, so that the first cleaning portion 12 is expanded in a polyhedral shape. The first cleaning part 12 is arranged on the bracket 111 and the supporting part 112 in a surrounding way, when the first driving part 14 moves, the first cleaning part 12 rolls relative to the supporting part 112, and because the first cleaning part 12 is unfolded in a polyhedral way, each surface on the first cleaning part 12 rolls alternately when rolling, so that the first cleaning part 12 can realize the effect of automatically changing the surface.

The cleaning assembly 10 is further provided with a second cleaning portion 13, the second cleaning portion 13 being in contact with the surface to be cleaned, while the second cleaning portion 13 is also in contact with the first cleaning portion 12. When the second driving part 15 moves, the second cleaning part 13 rolls. Since the second cleaning portion 13 is in contact with the surface to be cleaned, the second cleaning portion 13 can clean the surface to be cleaned. The second cleaning portion 13 is also in contact with the first cleaning portion 12, and the second driving portion 15 can rub against the first cleaning portion 12 when the second cleaning portion 13 rolls, so that the second cleaning portion 13 can clean the waste on the first cleaning portion 12. Thus, the cleaning assembly 10 can perform the function of automatically exchanging the surface of the first cleaning part 12 without frequently exchanging the first cleaning part 12, and the cleaning assembly 10 can also automatically clean the first cleaning part 12. The cleaning assembly 10 can reduce the times of manually replacing the first cleaning part 12 and cleaning the first cleaning part 12, save manpower and material resources and prevent secondary pollution.

The first cleaning portion 12 may be a rag, a dust cloth, a scouring pad, etc., which are not limited herein. The first cleaning part 12 is disposed around the bracket 111 and the plurality of supporting members 112, and the first cleaning part 12 is supported by the bracket 111 and the plurality of supporting members 112 and is expanded in a polyhedral shape. The first cleaning portion 12 includes a working surface 121, and the working surface 121 is a surface of the first cleaning portion 12 for contacting a surface to be cleaned.

When the cleaning assembly 10 is lowered by the lifting assembly, the first cleaning portion 12 is brought into contact with the surface to be cleaned, the second cleaning portion 13 is rolled to clean the surface to be cleaned, and the first cleaning portion 12 is held stationary to clean the surface to be cleaned. The second driving part 15 drives the second cleaning part 13 to roll relative to the support 112, and the surface to be cleaned can be cleaned when the second cleaning part 13 rolls because the second cleaning part 13 is in contact with the surface to be cleaned. Since the first cleaning portion 12 remains stationary and the first cleaning portion 12 is attached to the surface to be cleaned, the first cleaning portion 12 is also capable of cleaning the surface to be cleaned. The second cleaning portion 13 cleans the surface to be cleaned first, and the first cleaning portion 12 further cleans the surface to be cleaned after the cleaning by the second cleaning portion 13 is completed, so that the cleaning robot 100 cleans the surface to be cleaned more thoroughly, and the surface to be cleaned is cleaned more cleanly.

When the cleaning assembly 10 is lifted by the pulling assembly, the first cleaning portion 12 is separated from the surface to be cleaned, and the first cleaning portion 12 rolls with respect to the support 112 by the length of the working surface 121 to replace the working surface 121. After the cleaning assembly 10 cleans the surface to be cleaned for a period of time, the working surface 121 may have more garbage on the surface to be cleaned, the working surface 121 may not clean the surface to be cleaned any more, or the cleaning effect of the working surface 121 is poor. Since the first cleaning unit 12 is expanded in a polyhedral shape, the first driving unit 14 drives the first cleaning unit 12 to roll. The first cleaning part 12 rolls by the length of one working surface 121 relative to the support 112, the part of the first cleaning part 12 that has been soiled on the working surface 121 rolls to the other surface, and the clean part of the first cleaning part 12 rolls to the working surface 121, so that the first cleaning part 12 can continue to clean the surface to be cleaned. First cleaning portion 12 can realize the function of changing the face automatically, and at clean in-process, can reduce the number of times of changing first cleaning portion 12, the material resources of using manpower sparingly improve work efficiency.

When the cleaning assembly 10 is lifted by the lifting assembly, the first cleaning part 12 is separated from the surface to be cleaned, the first cleaning part 12 continuously rolls, the second cleaning part 13 rolls and rolls relative to the first cleaning part 12, and the second cleaning part 13 and the first cleaning part 12 rub against each other. After the first cleaning portion 12 has rolled one turn relative to the support 112, the entire first cleaning portion 12 is filled with debris. At this time, the first cleaning portion 12 has no cleaning effect or a poor cleaning effect, and may cause secondary contamination to the surface to be cleaned.

The first driving part 14 drives the first cleaning part 12 to continuously roll relative to the support 112, the second driving part 15 drives the second cleaning part 13 to roll, and the second cleaning part 13 rolls relative to the first cleaning part 12, i.e. the rolling direction of the second cleaning part 13 is opposite to that of the first cleaning part 12, or the rolling direction of the second cleaning part 13 is the same as that of the first cleaning part 12 and the rolling speed is different. Since the second cleaning portion 13 is in contact with the first cleaning portion 12, when the first cleaning portion 12 continuously rolls with respect to the second cleaning portion 13, the second cleaning portion 13 and the first cleaning portion 12 rub against each other, and the second cleaning portion 13 can clean the garbage on the first cleaning portion 12. After the second cleaning portion 13 cleans the first cleaning portion 12 for a period of time, the first cleaning portion 12 becomes cleaner, and the first cleaning portion 12 can clean the surface to be cleaned again. Therefore, the cleaning assembly 10 can automatically clean the first cleaning portion 12, reduce the number of times of replacing the first cleaning portion 12 during cleaning, save manpower and material resources, and improve the working efficiency of the cleaning robot 100.

In one example, the first cleaning portion 12 is a dust cloth. The circumference of one piece of dust cloth is 590 mm, and the length of the working surface 121 is 94 mm, so that the dust cloth rolls for six lengths of the working surface 121 relative to the support 112, i.e. rolls for one turn. In this example, the cleaning robot 100 has a small volume, a relatively simple structure, and a small cleaning area.

Referring to fig. 1, 5 and 6, the cleaning assembly 10 further includes a lifting bracket 18, a connecting bracket 19 and a travel switch 191.

Specifically, the lifting bracket 18 is connected with a hanging ring 181, and the lifting piece 31 is connected with the hanging ring 181. The lifting and lowering of the cleaning assembly 10 is accomplished by a pusher motor 32 controlling the lift. The connecting bracket 19 is connected with the supporting part 11, the connecting bracket 19 is also connected with a host computer, and the cleaning assembly 10 is connected with the host computer through the connecting bracket 19. The two ends of the connecting bracket 19 are respectively connected with the travel switches 191, and the travel switches 191 are arranged at the two ends of the connecting bracket 19, so that the cleaning robot 100 can be prevented from injuring a user in the moving process, such as pressing the foot of the user. When the cleaning robot 100 has a user at both ends or in front of the cleaning assembly 10 during the movement, the stroke switch 191 controls the cleaning robot 100 to stop the movement.

Referring to fig. 2, 7 and 8, the supporting portion 11 is a main portion of the cleaning assembly 10 for supporting various functional elements. The supporting portion 11 includes a bracket 111 and a supporting member 112, the bracket 111 includes a first sub-bracket 115 and a second sub-bracket 116, and the first sub-bracket 115 and the second sub-bracket 116 are disposed opposite to each other. The two ends of the supporting members 112 are respectively connected to the first sub-bracket 115 and the second sub-bracket 116. Thus, the plurality of supporters 112 are connected to the bracket 111 in a polyhedral shape. The first cleaning portion 12 is supported by the holder 111 and the plurality of supports 112 to be capable of being expanded in a polyhedral shape. The supporting function of the supporting member 112 and the supporting member 111 for the first cleaning part 12 can be enhanced by connecting both ends of the supporting member 112 to the first sub-holder 115 and the second sub-holder 116, respectively.
