The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1 and 2, the present embodiment provides a cleaning module 100 including an edge brush assembly 1 and a cleaning pad assembly 2 disposed at the bottom of the edge brush assembly 1. The side brush assembly 1 can clean the garbage on the surface to be cleaned. The cleaning pad assembly 2 is capable of wiping a surface to be cleaned. The side brush assembly 1 and the cleaning pad assembly 2 can be selectively operated.

In this embodiment, the edge brush assembly 1 includes a brush body 11 and a plurality of brush portions 12 arranged along the circumferential direction of the brush body 11. The brush body 11 is generally in the shape of a thick disc. The brush portion 12 is inclined downward, and the plurality of brush portions 12 form an approximately umbrella-shaped structure. The bristle part 12 optionally includes bristles and a connecting sleeve, and the bristles are connected with the brush body 11 through the connecting sleeve, which is the prior art and is not described in detail.

Illustratively, in order to increase the cleaning area and improve the cleaning capability, the bristle parts 12 are arranged in multiple groups, the multiple groups of bristle parts 12 are arranged at intervals up and down along the circumferential side wall of the brush body 11, and the multiple bristle parts 12 in each group are arranged at intervals circumferentially along the circumference of the brush body 11; alternatively, the plurality of brush hair portions 12 are spirally distributed on the circumferential side wall of the brush body 11.

When the side brush assembly 1 works, the brush body 11 inclines relative to a surface to be cleaned, the end part of the bristle part 12 on the inclined side is in contact with the surface to be cleaned, the brush body 11 rotates, the bristle part 12 rotates under the driving of the brush body 11, and the bristle parts 12 sequentially rotate to the inclined side. The end of the brush part 12 rotated to the inclined side cleans the garbage on the surface to be cleaned, and guides and gathers the garbage to the non-inclined side. Wherein, the inclined side is the side of the brush body 11 closer to the surface to be cleaned.

The distance and the inclination angle of the brush body 11 relative to the surface to be cleaned can be controlled, so that the end parts of all the bristle parts 12 on the inclined side can be in contact with the surface to be cleaned, the cleaning area is increased, and the cleaning efficiency and the cleaning capability are improved.

The cleaning pad assembly 2 is attached to the bottom of the brush body 11, i.e., the cleaning pad assembly 2 is located inside the approximately umbrella-like structure formed by the plurality of bristle parts 12. When the cleaning pad component 2 works, the bottom end face of the cleaning pad component is tightly attached to a surface to be cleaned, the cleaning pad component 2 rotates along with the brush body 11, and the surface to be cleaned is cleaned through the friction force between the cleaning pad component 2 and the surface to be cleaned.

Alternatively, the cleaning pad assembly 2 may comprise a cotton pad or a scouring pad. Compared with a cotton pad, the cleaning pad has stronger cleaning capability on a surface to be cleaned. The cotton pad is mainly used for wiping the surface to be cleaned to realize mopping. The scouring pad is mainly used for cleaning and even polishing the surface to be cleaned so as to realize ground washing. That is, the cleaning pad assembly 2 can be used for mopping or washing the floor.

The side brush assembly 1 mainly cleans large-particle garbage on a surface to be cleaned, and a floor sweeping mode is achieved. The cleaning pad assembly 2 mainly cleans and wipes small-particle garbage on a surface to be cleaned and garbage adhered to the surface to be cleaned, so that a mopping or floor washing mode is realized.

In this embodiment, when the bottom end surface of the cleaning pad assembly 2 is closely attached to the surface to be cleaned, the end of the bristle part 12 is separated from the surface to be cleaned. Meanwhile, the radius of the outer edge of the bottom of the approximately umbrella-shaped structure formed by the plurality of bristle parts 12 is larger than that of the cleaning pad 222. The brush body 11 can be tilted with respect to the surface to be cleaned so that the brush bristle part 12 and the cleaning pad assembly 2 can be alternatively brought into contact with the surface to be cleaned, thereby achieving an alternative operation of the edge brush assembly 1 and the cleaning pad assembly 2. Specifically, when the brush body 11 is not tilted with respect to the surface to be cleaned, the bottom end surface of the cleaning pad assembly 2 completely abuts against the surface to be cleaned, and the end portions of the bristle part 12 do not extend to the surface to be cleaned, i.e., only the cleaning pad assembly 2 operates, in a mopping or washing mode. When setting up brush body 11 and keeping away from the face of waiting to clean to when waiting to clean the face slope simultaneously, the bottom terminal surface of cleaning pad subassembly 2 with wait to clean the face separation, the tip that lies in brush hair portion 12 of the slope side of brush body 11 simultaneously with wait to clean the face contact, only limit brush subassembly 1 work this moment promptly, for the mode of sweeping the floor. That is, the cleaning module 100 of the present embodiment has an edge brush assembly operating state and a cleaning pad assembly operating state, and the two operating states are switched by tilting the brush body 11 with respect to the surface to be cleaned.

When cleaning, accessible control brush body 11 is for treating the inclination of cleaning the face, controls limit brush subassembly 1 and works earlier to treat the large granule rubbish on the cleaning face earlier and clean, later switch and clean the work of filling up subassembly 2, clean and clean with the rubbish of treating the tiny particle rubbish on the cleaning face and adhesion on the cleaning face. The edge brush assembly 1 serves as a pre-cleaning module and the cleaning pad assembly 2 serves as a secondary cleaning module to enhance the cleaning effect. The side brush assembly 1 cleans in advance of the cleaning pad assembly 2, and can avoid large-particle garbage on the surface to be cleaned from damaging the cleaning pad assembly 2, so that the service life of the cleaning module 100 is prolonged. In addition, the edge brush assembly 1 and the cleaning pad assembly 2 are integrated into one cleaning module, which can effectively reduce the size of the product.

Alternatively, the thickness of the cleaning pad assembly 2 can be designed to ensure that the ends of the bristle portion 12 do not contact the surface to be cleaned during operation of the cleaning pad assembly 2. That is, the thickness of the cleaning pad assembly 2 should ensure that the ends of the bristle part 12 do not contact the surface to be cleaned when the cleaning pad assembly 2 is pressed and deformed by the surface to be cleaned during operation.

Obviously, in other embodiments, it can be arranged that when the bottom end surface of the cleaning pad assembly 2 is completely attached to the surface to be cleaned, and the end of the brush bristle part 12 is also extended to the surface to be cleaned, the cleaning pad assembly 2 is operated, and the side brush assembly 1 is also operated at the same time, so as to improve the cleaning effect.

After finishing preliminary cleaning, the lifting component 4 continues to descend, the first trigger part 423 continues to contact with the second trigger part 31, the side brush component 1 and the cleaning pad component 2 thereon are driven by the first trigger part 423 to rotate reversely relative to the lifting component 4, namely, the side brush component 1 and the cleaning pad component 2 are inclined relative to the surface to be cleaned in the second direction (opposite to the first direction), the inclination angles of the side brush component 1 and the cleaning pad component 2 relative to the surface to be cleaned are reduced, the bristle part 12 on the inclined side of the brush body 11 is gradually separated from the surface to be cleaned, meanwhile, the bottom end face of the cleaning pad component 2 is gradually attached to and attached to the surface to be cleaned, and the cleaning module 100 is switched to the working state of the side brush component.

Specifically, the first trigger part 423 includes a protrusion, and the second trigger part 31 includes a rotation member. The protruding direction of setting up becomes the contained angle with the direction of going up and down of limit brush subassembly 1. The rotating member is located in the direction in which the projection ascends or descends. The projection includes a top end, an upper end, and a lower end. The top end is the end of the bulge deviating from the side brush component 1. The upper end and the lower end are both positioned at the root of the bulge and are respectively arranged at the two opposite ends of the bulge in the lifting direction. The convex outer profile includes a first profile and a second profile. The second profile extends from the apex of the projection to its upper end. The first profile extends from the top end of the projection to its lower end.

The lifting assembly 4 has upper and lower extreme positions which are opposite up and down. When the cleaning robot does not need to be cleaned, the lifting assembly 4 is located at the upper limit position, and the edge brush assembly 1 and the cleaning pad assembly 2 are both separated from the surface to be cleaned at the moment so as to avoid influencing the normal walking of the cleaning robot.

When cleaning work is needed, the lifting component 4 descends and drives the side brush component 1 and the cleaning pad component 2 on the side brush component to move towards the direction close to the surface to be cleaned. The movement of the side brush assembly 1 and the lifting assembly 4 is identical until the protrusions are not in contact with the rotating member. As the lifting assembly 4 continues to descend, the lower end of the projection first contacts the rotating member. The rotation piece rotates around its self axis under the effect with bellied frictional force, for continuing descending along with limit brush subassembly 1, contacts with the rotation piece by its lower extreme to each point on its top in proper order on the bellied first profile, and the result of contact is: the arch drives limit brush subassembly 1 and cleaning pad subassembly 2 and rotates for lifting unit 4, and limit brush subassembly 1 and cleaning pad subassembly 2 are for treating cleaning face first direction slope, along with continuing to descend, and turned angle constantly increases, brush hair portion 12 of 11 slopes sides of brush body with treat cleaning face contact, and cleaning pad subassembly 2's bottom surface with treat cleaning face contact, be limit brush subassembly operating condition this moment.

After the completion is cleaned tentatively, lifting unit 4 continues to descend, protruding through the second profile on by the top to the each point of upper end in proper order with rotate the piece contact, protruding through the second profile promptly with rotate the piece contact, the result of contact is: the arch drives limit brush subassembly 1 and clean subassembly and for 4 antiport of lifting unit, and limit brush subassembly 1 and cleaning pad subassembly 2 are for waiting to clean to the second direction (opposite with first direction) slope promptly, and limit brush subassembly 1 and cleaning pad subassembly 2 reduce for the inclination of waiting to clean the face, brush hair portion 12 of the slope side of brush body 11 gradually with wait to clean the face separation, the bottom terminal surface of cleaning pad subassembly 2 simultaneously gradually with wait to clean the face laminating and paste tightly. When the upper end of the protrusion contacts the rotation member (i.e., the protrusion is separated from the rotation member), the cleaning module 100 is switched to the cleaning pad assembly operating state when the lifting assembly 4 is lowered to the lower limit position (i.e., the lowest point).

After the edge brush assembly 1 finishes washing, the lifting assembly 4 is lifted from the lower limit position, the cleaning pad assembly 2 is separated from the surface to be cleaned, and meanwhile, the bulge is contacted with the rotating piece through points from the upper end to the top end of the second contour, and the contact result is as follows: the protrusion drives the side brush assembly 1 and the cleaning pad assembly 2 to rotate relative to the lifting assembly 4, the side brush assembly 1 and the cleaning pad assembly 2 incline towards the second direction relative to the surface to be cleaned, the brush hair part 12 on the inclined side of the brush body 11 gradually contacts with the surface to be cleaned, and the side brush assembly 1 can work or does not work at the moment. The angle of inclination of the edge brush assembly 1 and the cleaning pad assembly 2 with respect to the surface to be cleaned is maximized when the tips of the projections contact the rotating member. The lifting assembly 4 continues to rise, the projection then comes into contact with the rotating member through the first profile, as a result of which: the bulge drives the side brush assembly 1 and the cleaning pad assembly 2 on the side brush assembly to rotate reversely relative to the lifting assembly 4, the side brush assembly 1 and the cleaning pad assembly 2 incline towards the first direction relative to the surface to be cleaned, the inclination angles of the side brush assembly 1 and the cleaning pad assembly 2 relative to the surface to be cleaned are continuously reduced, and the brush hair part 12 on the inclined side of the side brush assembly 1 is gradually separated from the surface to be cleaned. When the lifting assembly 4 is lifted to the upper limit position, the side brush assembly 1 and the cleaning pad assembly 2 are completely separated from the surface to be cleaned.

It will be appreciated that the shape and size of the protrusions can be designed to ensure the angle of inclination of the edge brush assembly 1 and cleaning pad assembly 2 relative to the surface to be cleaned, and thus the sweeping effect.
