[0055] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by the person skilled in the art without making creative efforts are within the protection scope of the present application.

[0056] In order to realize the cleaning of the rolling brush, the existing cleaning equipment usually makes the squeegee into a comb tooth shape and is fixed on one side of the rolling brush, or uses a floating comb tooth squeegee which is pushed by a spring behind to realize the squeegeeing of the dirt on the rolling brush when the rolling brush rotates at high speed. In order to achieve the expected squeegeeing effect, the comb tooth squeegee needs to be in interference fit with the rolling brush to squeegee and suck the dirt, and under the driving of the rolling brush motor, the comb tooth squeegee is in interference fit with the rolling brush for a long time, which is easy to cause the abrasion of the bristles on the rolling brush, so that the bristles on the rolling brush are gradually shortened after long-term use of the cleaning equipment, the gap between the comb tooth squeegee and the rolling brush is increased, and the squeegeeing effect is gradually reduced.

[0057] When the cleaning equipment works normally, the main function is to remove the ground sewage and garbage by the rotation of the rolling brush, and the garbage is thrown and the water is splashed by the rotation of the rolling brush, so the rolling brush cover is usually installed on the rolling brush to avoid the problems of throwing garbage and splashing water. Because the main function of the rolling brush cover is to block the thrown garbage and splashed water, the rolling brush cover will be attached with garbage and sewage, so the rolling brush cover needs to be cleaned daily, and bacteria will breed and odor will be generated in the rolling brush cover if it is not cleaned for a long time.

[0058] During the self-cleaning process of the cleaning equipment on the base station, the rolling brush cover needs to be moved to a set self-cleaning position first so that the bristles on the rolling brush can contact the rolling brush cover, then the rolling brush is controlled to rotate forward and reverse to squeegee the dirt on the rolling brush cover, so as to realize the self-cleaning of the cleaning equipment. The whole control process is relatively complicated and high in cost. However, the self-cleaning process does not need the comb tooth squeegee to clean the dirt on the rolling brush, and the fixed squeegee or the floating squeegee cannot effectively avoid the rolling brush, which causes the long-time friction between the squeegee and the rolling brush, the length of the bristles on the rolling brush is shortened due to the long-time friction, the service life is shortened, the gap between the squeegee and the rolling brush is increased, the squeegeeing effect is reduced, and the cleaning effect is affected after a long time.

[0059] At present, in the industry, in order to solve the problem that the rolling brush of the cleaning equipment is easy to be abraded and the cleaning effect is gradually reduced after a long time, the rolling brush is usually replaced, the rolling brush needs to be replaced frequently, and the cost is high. Moreover, the existing self-cleaning equipment needs to be separately provided with a driving mechanism to drive the movement of the rolling brush cover, the control process is relatively complicated, the cost is high, and it is not conducive to the use and promotion of the product.

[0060] The embodiments of the utility model will be described below in combination with Figures 1 to 20 , the embodiments of the utility model.

[0061] According to the embodiment of the utility model, on the one hand, the utility model provides a ground brush device of cleaning equipment 100, ground brush device includes base 10, rolling brush subassembly 20, scrape dirty subassembly 30, rolling brush subassembly 20 includes rolling brush 21 and rolling brush cover 22, and rolling brush cover 22 is movably arranged on base 10;Scrape dirty subassembly 30 is movably arranged on base 10, and can move between the scraping position of interference fit with rolling brush 21 and the avoiding position of clearance fit with rolling brush 21;Linkage component 301, and scrape dirty subassembly 30 is connected with rolling brush cover 22 through linkage component 301, and when one of scrape dirty subassembly 30 and rolling brush cover 22 moves to the direction close to rolling brush 21, the other of scrape dirty subassembly 30 and rolling brush cover 22 moves to the direction away from rolling brush 21.

[0062] In the above embodiment, the reverse movement of the scraping assembly 30 and the rolling brush cover 22 relative to the rolling brush 21 means that when one of the scraping assembly 30 and the rolling brush cover 22 moves in the direction close to the rolling brush 21, the other of the scraping assembly 30 and the rolling brush cover 22 moves in the direction away from the rolling brush 21. For example, the cleaning equipment 100 has a working mode and a self-cleaning mode: when the cleaning equipment 100 is in the working mode, the scraping assembly 30 moves to the scraping position, and can drive the rolling brush cover 22 away from the rolling brush 21 and form a set gap between the rolling brush cover 22 and the rolling brush 21; when the cleaning equipment 100 is in the self-cleaning mode, the cleaning equipment 100 is located in the base station 200, the scraping assembly 30 moves to the avoiding position, and can drive the rolling brush cover 22 close to the rolling brush 21 and contact the bristles on the rolling brush 21 to realize self-cleaning of the rolling brush cover 22.

[0063] Specifically, by connecting the scraping assembly 30 with the rolling brush cover 22 through the linkage component 301, when the scraping assembly 30 moves to the avoiding position, the rolling brush cover 22 can be rotated to the self-cleaning position in contact with the rolling brush 21 under the driving of the linkage component 301, so that the rolling brush 21 can conveniently clean the rolling brush cover 22; when the scraping assembly 30 moves to the scraping position, the rolling brush cover 22 can be rotated to the initial position in clearance fit with the rolling brush 21 under the driving of the linkage component 301 and / or the action of the reset member, so as to effectively ensure that the cleaning equipment 100 has a set gap between the rolling brush cover 22 and the rolling brush 21 when normally performing cleaning work, and does not interfere with the movement of the rolling brush 21.

[0064] Specifically, when the scraping assembly 30 moves to the avoiding position, the linkage component 301 can convert the movement of the scraping assembly 30 into a downward movement pressure applied to the rolling brush cover 22, so that the rolling brush cover 22 is in contact with the rolling brush 21. The limiting fit mode of the linkage component 301 and the rolling brush cover 22 includes but is not limited to hinging, hooking, abutting and the like. Exemplarily, the linkage component 301 can adopt a hinge seat, a pull ring, a hook, a protrusion and the like.

[0065] When the cleaning device 100 is normally performing the cleaning work, the scraping assembly 30 moves to the scraping position in interference fit with the bristles of the roller brush 21, and can effectively clean the dirt on the bristles. After the cleaning work is completed, the whole machine is placed on the base station 200 to start the self-cleaning mode, the scraping assembly 30 moves to the avoiding position in clearance fit with the bristles of the roller brush 21, so that the scraping assembly 30 is separated from the roller brush 21, avoiding the problem of interference fit between the two and bristle wear during the self-cleaning mode. At the same time, since the scraping assembly 30 is in linkage fit with the roller brush cover 22, the scraping assembly 30 can drive the roller brush cover 22 to rotate towards the roller brush 21 when moving to the avoiding position, so that the roller brush cover 22 is kept close to the roller brush 21. At this time, the self-cleaning of the roller brush cover 22 can be realized by controlling the forward and reverse rotation of the roller brush 21.

[0066] In the present application, the scraping assembly 30 is linked with the roller brush cover 22. When the cleaning device 100 is performing self-cleaning, the scraping assembly 30 can not only move to the avoiding position to avoid the roller brush 21 and reduce the friction therebetween, thereby prolonging the service life of the roller brush 21 and reducing the replacement frequency of the roller brush 21, but also drive the roller brush cover 22 to move to the position in contact with the roller brush 21, thereby cleaning the dirt on the roller brush cover 22. Only one driving device 40 is needed to control the movement of the scraping assembly 30 and the roller brush cover 22, thereby saving the control cost, simplifying the control steps, and effectively solving the problem of the related art that the scraping assembly 30 and the roller brush cover 22 of the self-cleaning device need to be separately provided with driving mechanisms for driving, and the control process is relatively complicated and high in cost.

[0067] In the present embodiment, the roller brush cover 22 is located above the roller brush 21, and the roller brush cover 22 and the scraping assembly 30 can be in linkage transmission fit or direct contact fit. When the cleaning device 100 is normally performing the cleaning work, the roller brush 21 rotates at high speed, the scraping assembly 30 is in the scraping position in interference fit with the bristles of the roller brush 21, and can timely scrape the dirt on the bristles. At this time, the roller brush cover 22 has a set gap with the roller brush 21, and the dirt on the roller brush 21 that is not scraped off by the scraping assembly 30 can be thrown onto the roller brush cover 22 under the action of centrifugal force. When the cleaning device 100 completes the cleaning work and is placed in the base station 200, the roller brush 21 no longer performs the cleaning work, and the scraping assembly 30 does not need to clean the roller brush 21. The scraping assembly 30 moves to the avoiding position in clearance fit with the bristles of the roller brush 21. At this time, the roller brush cover 22 rotates downward under the linkage of the scraping assembly 30, and keeps close to the roller brush 21. Then, the self-cleaning of the dirt attached to the roller brush cover 22 is realized by controlling the forward and reverse rotation of the roller brush 21.

[0068] In some embodiments, the rolling brush cover 22 is rotatably arranged on the base 10 through a first rotating shaft, and the rolling brush cover 22 comprises a rolling brush cover body 221 and a connecting portion 222 which are arranged in a distributed manner and connected with the first rotating shaft, and the connecting portion 222 drives the rolling brush cover body 221 to move towards or away from the rolling brush 21 through the linkage component 301.

[0069] In the above embodiments, one end of the connecting portion 222 is fixed with the rolling brush cover body 221, the other end is limitedly matched with the linkage component 301, and the middle part is rotatably connected with the base 10 through the first rotating shaft; when the scraping assembly 30 moves to the scraping position, the rolling brush cover body 221 can be rotated away from the rolling brush 21 under the driving of the linkage component 301; when the scraping assembly 30 moves to the avoiding position, the linkage component 301 can push the rolling brush cover body 221 to rotate towards the rolling brush 21 through the connecting portion 222.

[0070] The rolling brush cover 22 is designed by using the above connecting portion 222, which can not only realize the rotating connection between the rolling brush cover 22 and the base 10, but also realize the linkage between the rolling brush cover 22 and the scraping assembly 30 through the limited matching with the linkage component 301, which is multi-purpose and further simplifies the structure. In addition, the connecting portion 222 is rotatably connected with the base at the middle part and matched with the rolling brush cover body and the scraping assembly at both ends, so that the whole rolling brush cover 22 forms a lever structure, which can change the direction of force, so that the whole rolling brush cover forms a lever structure, which can change the direction of force, so that the scraping assembly can drive the rolling brush cover body to move downward when pushing the connecting portion upward, which is close to the rolling brush. Not only the position of the scraping assembly is not limited, but also the installation and layout of the scraping assembly are facilitated, and the scraping assembly can drive the rolling brush cover to move more easily and labor-savingly.

[0071] Specifically, the rolling brush cover body 221 is an arc-shaped plate structure, the middle part of the connecting portion 222 is provided with a first shaft hole, the first shaft hole and the base 10 are connected through the first rotating shaft 23, and the rotating connection between the rolling brush cover 22 and the base 10 is realized. Of course, in other alternative embodiments, the middle part of the connecting portion 222 can be integrally provided with the first rotating shaft 23.

[0072] When the cleaning device 100 normally performs the cleaning work, the scraping assembly 30 moves to the scraping position, at this time, the rolling brush cover body 221 can be rotated away from the rolling brush 21 under the driving of the linkage component 301, so as to avoid interfering with the high-speed rotating rolling brush 21; when the cleaning device 100 performs self-cleaning, the scraping assembly 30 moves to the avoiding position, at this time, the linkage component 301 can push the rolling brush cover body 221 to rotate towards the rolling brush 21 through the connecting portion 222, so that the rolling brush cover body 221 is in contact with the bristles of the rolling brush 21, at this time, the dirt on the inner wall of the rolling brush cover body 221 is cleaned by controlling the rolling brush 21 to rotate in reverse.

[0073] In some embodiments, the linkage component 301 is configured to be in contact with the connection part 222 of the roller brush cover main body 221. Figures 18 to 20 As shown, the linkage component 301 includes a push protrusion arranged on the squeegee assembly 30 and abutting against the connection part 222. When the squeegee assembly 30 moves away from the roller brush 21, the push protrusion of the squeegee assembly 30 pushes the connection part 222 to move the roller brush cover main body 221 towards the roller brush 21.

[0074] In the above embodiments, the linkage component 301 is in the form of a push protrusion, which is simple in structure and easy to process and form. The linkage between the squeegee assembly and the roller brush cover is achieved by the abutting contact between the push protrusion and the roller brush cover, which is simpler and more reliable than the hinged or hooked mode, and is also convenient for disassembly and maintenance.

[0075] Further, the roller brush cover main body 221 has an inner side wall facing the roller brush 21 and an outer side wall facing away. The connection part 222 is a connecting rib fixedly arranged on the outer side wall, and the connecting rib is in abutting contact with the push protrusion. The connection part 222 is in the form of a connecting rib fixedly arranged on the outer side wall of the roller brush cover main body 221, which is simple in structure and easy to process and form.

[0076] Specifically, the linkage component 301 is a protrusion fixedly arranged on the squeegee assembly 30. The connecting rib includes a shaft body part in the middle and first and second arm body parts arranged at a set angle on both sides of the shaft body part. The shaft body part has a shaft hole formed therein. The end of the first arm body part is fixed to the outer side wall of the roller brush cover main body 221, and the end of the second arm body part is configured as an abutting end adapted to abut against the linkage component 301.

[0077] Further, along the axial direction of the roller brush 21, the two ends of the roller brush cover main body 221 are provided with two groups of connection parts 222. Correspondingly, two groups of linkage components 301 are arranged. The two groups of linkage components 301 are in one-to-one corresponding contact with the two groups of connection parts 222. Through the two groups of connection parts 222 arranged at the two ends of the roller brush cover main body 221 and the two groups of linkage components 301 arranged correspondingly, the two groups of linkage components 301 are in one-to-one corresponding abutting contact with the two groups of connection parts 222, so as to push the roller brush cover main body 221 from both sides, making the movement of the roller brush cover main body 221 more balanced and stable.

[0078] In some embodiments, the roller brush assembly 20 further includes a first reset member 24 arranged on the first rotating shaft 23. The first rotating shaft 23 is connected to the base 10 through the first reset member 24. When the squeegee assembly 30 moves towards the roller brush 21, the first reset member 24 can apply a reset force to the roller brush cover main body 221 to move away from the roller brush 21.

[0079] In the above embodiment, the first reset member arranged on the first rotating shaft can make the roller brush cover have a tendency to rotate away from the roller brush. When the scraping assembly moves to the scraping position and no longer presses the roller brush cover, the first reset member can provide an upward reset force to the roller brush cover body, so that the roller brush cover can automatically reset to the initial position in which the roller brush cover cooperates with the gap of the roller brush, thereby effectively ensuring the normal cleaning work.

[0080] Preferably, the first reset member 24 is a torsion spring, which is sleeved on the first rotating shaft 23 and abuts against the roller brush cover body 221 and the base 10 at two ends. When the push protrusion does not push the connecting portion to press the roller brush cover body, the torsion spring can provide an upward reset force to the roller brush cover body, so that the roller brush cover body and the roller brush restore the gap to normally perform the cleaning work.

[0124] When the floor cleaning machine finishes cleaning the floor, it is placed in the base station 200, and after receiving the self-cleaning instruction, the driving motor 411 drives the scraper 32 to rotate backward through the transmission mechanism 42, when the trigger 4211 on the driving gear 421 touches the second position switch 45, the driving motor 411 stops rotating backward, at this time the scraper rotates to the last end, the scraper 32 is separated from the roller brush 21, the scraper 32 and the bristles keep a gap, and self-cleaning can be performed, at the same time, the linkage part 301 on the scraper 32 rotates upward, drives the linkage roller brush cover 22, and drives the roller brush cover 22 to rotate downward, so that the roller brush cover 22 is slightly interference-fitted with the bristles on the roller brush 21, and the bristles can clean the dirt on the roller brush cover 22 after the roller brush starts to rotate.

[0125] The cleaning device 100 provided in the embodiment mainly improves the dirt scraping function of the scraper 32 and the service life of the roller brush 21, under the premise of ensuring the dirt scraping performance of the scraper 32, in order to increase the service life of the roller brush 21, the scraper 32 is controlled to be separated from the roller brush 21 during self-cleaning, the friction between the scraper 32 and the roller brush 21 is reduced, the linkage between the dirt scraping assembly 30 and the roller brush cover 22 can also realize the cleaning function of the roller brush cover 22, the service life of the roller brush 21 is improved, and the dirt on the roller brush cover 22 is also cleaned synchronously, the self-cleaning of the dirt on the roller brush cover 22 is realized, and the service life of the roller brush 21 and the cleaning effect of the whole machine are improved.

[0126] 3. The control method of the cleaning device 100 is as follows:

[0127] Step A, working mode, including intelligent mode or strong mode, which is to select whether cleaning is needed according to the user's judgment;

[0128] Step B, self-cleaning mode; which is to select whether self-cleaning is needed according to the user's judgment;
