[0041] To enable those skilled in the art to more clearly understand this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0042] To address the technical problems mentioned in the background art, this disclosure provides a roller brush cleaning device, cleaning equipment, and cleaning system to prevent the accumulation of debris on the roller brush surface, improve the cleaning effect of the cleaning equipment, and ensure the normal operation of the roller brush.

[0043] The design concept of the roller brush cleaning device disclosed herein is as follows: the scraper abuts against the surface of the roller brush to clean the debris on the surface of the roller brush, so as to avoid affecting the cleaning effect of the cleaning equipment and the normal operation of the roller brush. The seal at the bottom of the scraper fills the gap at the bottom of the scraper to prevent the debris cleaned from the surface of the roller brush from entering the support through the gap between the scraper and the support of the bracket, thus affecting the rotation of the scraper and ensuring the cleaning effect on the surface of the roller brush.

[0044] Specific technical solutions will now be described in detail with reference to the accompanying drawings, which are not necessarily drawn to scale. In the drawings, similar or identical reference numerals may be used to designate the same or similar parts in different figures. The use of similar or identical reference numerals in different figures does not mean that all figures including similar or identical reference numerals constitute a single or the same embodiment. The accompanying drawings illustrate the various embodiments discussed in this disclosure in a generalized, illustrative, and not restrictive manner.

[0045] Figure 1 shows a partial structural schematic diagram of a cleaning device according to one or more embodiments of the present disclosure; Figure 2 shows a structural schematic diagram of a roller brush cleaning device according to some embodiments of the present disclosure; Figure 3 shows a top view of the roller brush cleaning device in Figure 2; Figure 4 shows a cross-sectional schematic diagram of AA in Figure 3; and Figure 5 shows an enlarged schematic diagram of point A in Figure 4. Referring to Figures 1-5, the roller brush cleaning device A provided by the present disclosure is used to clean the surface of a roller brush 500. The device includes a support 100, a scraper 200, and a seal 300. The support 100 is provided with a support portion 101. The scraper 200 is connected to the support 100, at least a portion of the scraper 200 is disposed on the support portion 101, and the scraper 200 abuts against the surface of the roller brush 500. The seal 300 is disposed on the support portion 101, and at least a portion of the seal 300 elastically abuts against the scraper 200.

[0046] The roller brush cleaning device A provided in this disclosure, since the scraper 200 is connected to the bracket 100 and abuts against the surface of the roller brush 500, can clean the debris on the surface of the roller brush 500 during operation, thus ensuring the cleaning effect of the cleaning equipment. Since at least a portion of the gap of the scraper 200 is placed on the support portion 101 of the bracket 100, and the seal 300 is placed on the support portion 101, with at least a portion of the seal 300 elastically abutting against the scraper 200, the seal 300 can fill the gap between the scraper 200 and the support portion 101 of the bracket 100, preventing debris cleaned from the surface of the roller brush 500 from entering the bracket 100 through the gap between the scraper 200 and the support portion 101 of the bracket 100, thereby affecting the rotation of the scraper 200, and ensuring the normal operation of the roller brush 500, has good practicality. The specific details of the roller brush cleaning device A are now further described with reference to Figures 1-13.

[0047] Referring to Figures 1 and 2, according to one embodiment of this disclosure, the roller brush 500 is rotatably mounted on the base 400 of the cleaning equipment. A bracket 100 may be integrated into the base 400 of the cleaning equipment. The bracket 100 and the roller brush 500 are spaced apart. For ease of description, the side of the bracket 100 facing the roller brush 500 is defined as the front side, and the side of the bracket 100 facing away from the roller brush 500 is defined as the rear side.

[0048] Figure 6 shows a schematic diagram of the base of the roller brush cleaning device in Figure 2. Referring to Figure 6, the support 100 includes a partition plate 102 and two side plates 103. The partition plate 102 is placed within the base 400 to divide the base 400 into a water-receiving area and a mounting area for the roller brush 500. The two side plates 103 are arranged opposite each other on both sides of the front side of the partition plate 102. The side plates 103 of the support 100 are provided with receiving grooves 104 that match at least a portion of the circumferential surface of the roller brush 500. At least a portion of the circumferential surface of the roller brush 500 rotates within the receiving grooves 104 to clean the floor.

[0049] Referring to Figure 6, a rotating shaft 105 is provided on the bracket 100. The scraper 200 is rotatably connected to the rotating shaft 105. Since the scraper 200 abuts against the surface of the roller brush 500, during the rotation of the roller brush 500, the rotating roller brush 500 generates friction with the scraper 200, thereby driving the scraper 200 to rotate.

[0050] Referring to Figure 6, in one embodiment, the bracket 100 has two rotating shafts 105 on opposite sides of its two side plates 103, meaning the bracket 100 has two rotating shafts 105. There is a gap between the two rotating shafts 105. Mounting holes 201 are provided on both sides of the scraper 200 along its length. The rotating shaft 105 is movably fitted into the mounting hole 201 on the same side of the scraper 200, so that the scraper 200 is rotatably fitted into the bracket 100. In another embodiment, the two side plates 103 of the bracket 100 can also be connected by a rotating shaft 105. This rotating shaft 105 passes through the scraper 200, so that the scraper 200 is rotatably fitted into the bracket 100.

[0051] Figure 7 shows an exploded view of the roller brush cleaning device in Figure 2. Referring to Figure 7, the scraper 200 and the support 100 are also connected by an elastic element 600. During the rotation of the roller brush 500, as the rotating roller brush 500 drives the scraper 200 to rotate, the elastic element 600 ensures that the scraper 200 can only oscillate within a preset angle, forming a floating posture to adapt to different types of debris on the surface of the roller brush 500, thus ensuring the effective cleaning of the roller brush 500 surface by the scraper 200.

[0052] Figure 8 shows a schematic diagram of the structure of the scraper in Figure 7. Referring to Figure 8, the scraper 200 includes a back plate 202. The top of both sides of the back plate 202 are provided with the aforementioned mounting holes 201, so that the back plate 202 is rotatably connected to the pivot 105 of the bracket 100.

[0053] Referring to Figures 7 and 8, the elastic element 600 can be a spring, with one end connected to the rear side of the back plate 202 and the other end connected to the partition plate 102. In some embodiments, one end of the elastic element 600 can be snapped or welded to the rear side of the back plate 202, and the other end of the elastic element 600 can pass through the partition plate 102 and abut against a component in the water-retaining area to guide the deformation of the elastic element 600. To improve the elastic support effect on the scraper 200, two or more elastic elements 600 can be provided at intervals. In another embodiment, the other end of the elastic element 600 can also be directly connected to the front side of the partition plate 102.

[0054] Referring to Figures 7 and 8, the scraping component 200 also includes a scraper 203. The scraper 203 is connected to the front side of the bottom of the back plate 202, so that the scraping component 200 is approximately L-shaped. The front side of the scraper 203 preferably faces below the central axis of the roller brush 500 to effectively clean the debris on the surface of the roller brush 500. In one embodiment, the scraper 203 can be detachably connected to the bottom of the back plate 202 by means of screws or other connectors; in another embodiment, the scraper 203 can also be integrally formed with the back plate 202, as long as the scraper 203 is fixedly connected to the back plate 202 and rotates synchronously, the connection method between the two is not limited here.

[0055] Figure 9 shows a schematic cross-sectional view of BB in Figure 3. Referring to Figure 9, in order to enable the scraper 200 to swing within a set angle, in some embodiments, the bracket 100 is provided with a constraint part 106, and the scraper 200 is provided with a limiting part 204. The limiting part 204 swings back and forth within the constraint part 106 at a set angle to ensure the cleaning effect of the scraper 200 on the surface of the roller brush 500.

[0056] Referring to Figure 9, the constraint portion 106 is provided with an opening. At least a portion of the limiting portion 204 is placed within the constraint portion 106 through the opening. The limiting portion 204 is provided with a limiting protrusion 2053. The limiting protrusion 2053 reciprocates in the middle of the constraint portion 106 and is constrained by both sides of the constraint portion 106, so as to limit the swing amplitude of the limiting protrusion 2053 of the limiting portion 204 within the constraint portion 106, and limit the swing amplitude of the scraper 200 relative to the bracket 100, thereby ensuring the cleaning effect of the scraper 200 on the surface of the roller brush 500.

[0057] According to one embodiment of this disclosure, the distance from the limiting protrusion 2053 to the rotating shaft 105 must be greater than the distance from both sides of the restraining portion 106 to the rotating shaft 105, and less than the distance from the middle of the restraining portion 106 to the rotating shaft 105, so that the limiting protrusion 2053 swings back and forth in the middle of the restraining portion 106 and is restrained by both sides of the restraining portion 106. It should be noted that the distance from the restraining portion 106 to the rotating shaft 105 can be variable or fixed, but it must be ensured that the distance from the restraining portion 106 to the rotating shaft meets the above setting.

[0058] Figure 10 shows an enlarged schematic diagram of section B in Figure 6. Referring to Figure 6, a first hook-shaped structure 107 is provided on the front side of the partition plate 102. The first hook-shaped structure 107 is located below the rotating shaft 105 and can be integrally formed with the partition plate 102. The first hook-shaped structure 107 includes a first plate 1071 and a second plate 1072, which are sequentially connected to the partition plate 102 to form the aforementioned constraint part 106. In some embodiments, the first plate 1071 may be arranged perpendicularly to the partition plate 102, and the second plate 1072 may be inclined upward toward the front side of the bracket 100; the first plate 1071 is configured as the middle part of the constraint part, and the partition plate 102 and the second plate 1072 are configured as the two sides of the constraint part; the limiting protrusion 2053 of the limiting part 204 reciprocates inside the first plate 1071 and is constrained by the partition plate 102 and the second plate 1072 to limit the swing amplitude of the limiting protrusion 2053 of the limiting part 204.

[0059] Figure 11 shows an enlarged schematic diagram of point C in Figure 8. Referring to Figure 11, the scraper 200 is provided with a second hook-shaped structure 205. This second hook-shaped structure 205 includes a third plate 2051 and a fourth plate 2052. The fourth plate 2052 is connected to the front side of the bottom of the third plate 2051 and is inclined upwards towards the roller brush 500. A limiting protrusion 2053 is located at the bottom of the connection between the fourth plate 2052 and the third plate 2051. When the scraper 200 is not rotating, the third plate 2051 is attached to the front side of the partition plate 102, and the fourth plate 2052 is placed on the upper side of the second plate 1072, with a certain gap between them. When the scraper 200 rotates, the limiting protrusion 2053 rotates above the first plate 1071 and is limited by the second plate 1072 and the partition plate 102, thereby limiting the swing amplitude of the limiting protrusion 2053 of the limiting part 204, and thus controlling the swing amplitude of the scraper 200.

[0060] According to one embodiment of this disclosure, a limiting portion 204 is provided on at least one side of the scraper 200 along its length. A restraining portion 106 is provided between the bracket 100 and the scraper 200. Providing a limiting portion 204 on at least one side of the scraper 200 along its length means that the limiting portion 204 can be provided on both sides of the scraper 200 along its length, or it can be provided only on one side of the scraper 200 along its length. In some embodiments, the limiting portion 204 can be integrally formed on the side of the back plate 202 along its length.

[0061] Figure 12 shows a structural schematic diagram of a bracket with a support portion. Referring to Figure 12, the bracket 100 may further include a support plate 108, which can be snap-fitted or integrally formed to the front side of the middle portion of the partition plate 102. This support plate 108 is configured as the support portion 101 of the bracket 100.

[0062] Referring to Figure 12, a positioning recess 1081 is provided on the front side of the support plate 108 of the bracket 100. The seal 300 is assembled in the positioning recess 1081 on the front side of the support plate 108 of the bracket 100. The top surface of the seal 300 can be on the same plane as the top surface of the support plate 108.

[0063] Figure 13 shows a schematic diagram of the seal in Figure 7. Referring to Figure 13, a sealing protrusion 301 is provided on the top of the seal 300. The sealing protrusion 301 elastically abuts against the scraper 200. Since the scraper 200 reciprocates, during this reciprocating motion, the sealing protrusion 301 is compressed, ensuring a seamless connection between the scraper 200 and the support portion 101 of the bracket 100. This prevents debris cleaned from the surface of the roller brush 500 from entering the bracket 100 through the gap between the scraper 200 and the support portion 101, thus affecting the rotation of the scraper 200 and ensuring effective cleaning of the roller brush 500 surface. It should be noted that during the reciprocating swing of the scraper 200, the bottom of the scraper 203 of the scraper 200 is always in contact with the sealing protrusion 301 of the seal 300. However, the degree of compression of the sealing protrusion 301 varies under different swing amplitudes of the scraper 200.

[0064] Referring to Figure 13, in one embodiment, the sealing protrusion 301 is inclined to the top of the seal 300 and extends toward the roller brush 500, so that the sealing protrusion 301 and the seal 300 form a Y-shaped structure to block debris from the surface of the roller brush 500. In another embodiment, the sealing protrusion 301 may also be perpendicular to the top of the seal 300, or the sealing protrusion 301 may extend away from the roller brush 500 (towards the partition plate 102 of the support 100), which can also block debris from the surface of the roller brush 500.

[0065] Referring to Figure 13, the bottom of the seal 300 is provided with a plurality of connecting protrusions 302 at intervals, and the plurality of connecting protrusions 302 are fixedly engaged with the positioning recess 1081 on the front side of the support plate 108. In another embodiment, the seal 300 may also be bonded or / and screwed to the positioning recess 1081 on the front side of the support plate 108.

[0066] Referring to Figure 12, the support part 101 has multiple comb teeth 700 spaced apart on its side facing the roller brush 500. During the operation of the roller brush 500, the debris on the surface of the roller brush 500 is combed by the multiple comb teeth 700, and with the cleaning of the surface of the roller brush 500 by the scraper 200, the cleaning effect of the surface of the roller brush 500 can be further improved.

[0067] Referring to Figure 12, in one embodiment, the support portion 101 has mounting protrusions 109 on its bottom and / or top sides facing the roller brush 500. Multiple comb teeth 700 are spaced apart on the mounting protrusions 109. The mounting protrusions 109 may protrude from the front of the support portion 101 and be inclined away from the support portion 101, thereby improving the combing effect on debris on the surface of the roller brush 500. In another embodiment, the mounting protrusions 109 may also be located at the bottom of the support portion 101, or both the bottom and top of the support portion 101 may have the aforementioned mounting protrusions 109; no limitation is made here.

[0068] In the related technology, the roller brush 500 includes a brush body and a mop on the surface of the brush body. Multiple comb teeth 700 are tangent to the brush body of the roller brush 500, or multiple comb teeth 700 are tangent to the concentric circles of the roller brush 500. When the cleaning equipment is working, the multiple comb teeth 700 have a certain amount of interference with the mop on the roller brush 500. This amount of interference can be about 0.4 mm to ensure the cleaning effect on the surface of the roller brush 500.

[0069] Referring to Figure 6, a suction port 1010 is also provided on the partition plate 102. The suction port 1010 is located below the support part 101 of the bracket 100. The suction port 1010 is connected to the sludge collection box of the cleaning equipment. A fan is also provided inside the cleaning equipment. Under the action of the fan, a negative pressure is formed inside the sludge collection box. The garbage cleaned by the cleaning device is sucked into the sludge collection box for collection, so as to ensure the cleaning effect of the roller brush 500.

[0070] Figure 14 shows a structural schematic diagram of a roller brush cleaning device B according to another embodiment of the present disclosure; Figure 15 shows a top view of the roller brush cleaning device in Figure 14; Figure 16 shows a CC cross-sectional view of Figure 15. Referring to Figures 14-16, the roller brush cleaning device B provided by the present disclosure is used to clean the surface of a roller brush 500. The device includes a support 100 and a scraper 200. The support 100 is provided with a separate support portion 101. The scraper 200 is connected to the support 100. The scraper 200 abuts against the surface of the roller brush 500. The bottom of the scraper 200 abuts against the support portion 101.

[0071] The roller brush cleaning device B provided in this disclosure features a scraper 200 connected to the support 100 and resting against the surface of the roller brush 500. During operation of the roller brush 500, the scraper 200 cleans debris from its surface, ensuring effective cleaning. Since the scraper 200 abuts against the support 101, and the support 101 is separate from the support 100, the support 101 can rotate synchronously with the scraper 200. There are no gaps between the scraper 200 and the support 101, preventing debris cleaned from the roller brush 500 from entering the support 100 through gaps and affecting its rotation. This ensures the roller brush 500 operates normally and provides excellent practicality. Further details of the roller brush cleaning device B are now described with reference to Figures 14-19.

[0072] The roller brush cleaning device B shown in Figure 14 is a type of roller brush cleaning device, similar to roller brush cleaning device A. This roller brush cleaning device B also includes an elastic element 600, a rotating shaft 105, a restraining part 106, and a limiting part 204. Unless otherwise specified, the structure and function of these components in roller brush cleaning device B are substantially the same as those in roller brush cleaning device A; therefore, the corresponding description of roller brush cleaning device A can be referred to, and will not be repeated here.

[0073] Figure 17 shows a schematic diagram of the scraper with a support portion of the roller brush cleaning device in Figure 14; Figure 18 shows a schematic diagram of the scraper in Figure 17; Figure 19 shows a schematic diagram of the scraper in Figure 17. Referring to Figures 17-19, the scraper 200 also includes a clamping portion 206. This clamping portion 206 is positioned above the support portion 101 at a distance. The scraper 203 of the scraper 200 is disposed between the clamping portion 206 and the support portion 101. The thickness of the scraper 200 matches the gap between the clamping portion 206 and the support portion 101, so that the support 100 forms a sealed structure to prevent debris cleaned from the surface of the roller brush 500 from entering the support 100 through the gap between the clamping portion 206 and the support portion 101. In some embodiments, the head of the scraper 203 extends out of the clamping portion 206 and the support portion 101 of the scraper 200 so that the scraper 203 can contact the surface of the roller brush 500 to clean the debris on the surface of the roller brush 500.

[0074] Referring to Figures 18 and 19, in one embodiment, a plurality of spaced-apart connecting posts 207 are provided between the clamping part 206 and the support part 101. The scraper 203 is also provided with mounting holes 2031. The connecting posts 207 and mounting holes 2031 are correspondingly provided. The connecting posts 207 are inserted into the corresponding mounting holes 2031 to limit the displacement of the scraper 203, thereby ensuring the reliability of the assembly of the scraper 203 between the clamping part 206 and the support part 101 of the scraping member 200.

[0075] In one embodiment, the clamping portion 206 and the supporting portion 101 of the scraper 200 can be integrally formed with the scraper 203. In some embodiments, the scraper 203 of the scraper 200 can be made of metal, while other structures of the scraper 200 can be made of plastic, and these other structures are integrally formed with the scraper 203. In another embodiment, the clamping portion 206 and the supporting portion 101 of the scraper 200 can also be connected to the scraper 203 by bolts or other connecting members, and this is not limited thereto.

[0076] Referring to Figures 17 and 18, the support 101 is also a plate-like structure, positioned between the two side plates 103 of the bracket 100, and oscillating back and forth between the two side plates 103. Under the action of the elastic member 600, the side of the support 101 facing away from the roller brush 500 (the rear side of the support 101) has a certain gap with the partition plate 102 of the bracket 100. Multiple comb teeth 700 are spaced apart on the side of the support 101 facing the roller brush 500 (the front side of the support 101). During the operation of the roller brush 500, debris on the surface of the roller brush 500 is combed by the multiple comb teeth 700, and combined with the cleaning of the roller brush 500 surface by the scraper member 200, the cleaning effect of the roller brush 500 surface can be further improved.

[0077] As can be seen from the above, the main difference between the roller brush cleaning device A and the roller brush cleaning device B provided in this disclosure is that the scraping component 200 and the support portion 101 in the roller brush cleaning device A are spaced apart, and the gap between them is filled by the sealing component 300. In the roller brush cleaning device B, the scraping component 200 and the support portion 101 are integrated together, therefore, the sealing component 300 in the roller brush cleaning device A can be eliminated.
