In combination with Figures 1-5 , the rolling brush cleaning device A provided by the application is used for cleaning the surface of the rolling brush 500, and the device comprises a support 100, a dirt scraping piece 200 and a sealing piece 300, wherein the support 100 is provided with a supporting part 101, the dirt scraping piece 200 is connected to the support 100, at least part of the gap of the dirt scraping piece 200 is arranged on the supporting part 101, and the dirt scraping piece 200 abuts against the surface of the rolling brush 500; the sealing piece 300 is arranged on the supporting part 101, and at least part of the sealing piece 300 abuts elastically against the dirt scraping piece 200.

[0051] The rolling brush cleaning device A provided by the application, since the dirt scraping piece 200 is connected to the support 100, the dirt scraping piece 200 abuts against the surface of the rolling brush 500, and during the operation of the rolling brush 500, the garbage on the surface of the rolling brush 500 can be cleaned by the dirt scraping piece 200, so as to guarantee the cleaning effect of the cleaning equipment; since at least part of the gap of the dirt scraping piece 200 is arranged on the supporting part 101 of the support 100, the sealing piece 300 is arranged on the supporting part 101, and at least part of the elastic sealing piece 300 abuts against the dirt scraping piece 200, therefore, the gap between the dirt scraping piece 200 and the supporting part 101 of the support 100 can be filled by the sealing piece 300, so as to avoid the garbage cleaned from the surface of the rolling brush 500 from entering the support 100 through the gap between the dirt scraping piece 200 and the supporting part 101 of the support 100, and then affecting the rotation of the dirt scraping piece 200, so that the rolling brush 500 can normally operate, and the rolling brush cleaning device A has good practicability. Figure 1 -attached Figure 13 , the specific details of the rolling brush cleaning device A are further described.

[0052] Combined Figure 1 and Figure 2 According to an embodiment of the application, the rolling brush 500 is rotatably installed on the base 400 of the cleaning equipment, the support 100 can be integrated on the base 400 of the cleaning equipment, and the support 100 and the rolling brush 500 are arranged in a spaced manner. For the sake of convenience, it is defined that the side of the support 100 facing the rolling brush 500 is defined as the front side, and the side of the support 100 facing away from the rolling brush 500 is defined as the back side.

[0053] Figure 6 The structure diagram of the base in Figure 2 is shown. Combined with Figure 6 , the support 100 includes a partition plate 102 and two side plates 103, the partition plate 102 is arranged in the base 400 to separate the base 400 into a water containing area and a mounting area of the rolling brush 500, the two side plates 103 are arranged opposite to the two sides of the front side of the partition plate 102, the side plate 103 of the support 100 is provided with a containing groove 104 matching at least part of the circumferential surface of the rolling brush 500, and at least part of the circumferential surface of the rolling brush 500 rotates in the containing groove 104 to clean the ground.

[0054] Combined with Figure 6 , the support 100 is provided with a rotating shaft 105, and the dirt scraping piece 200 is rotatably connected to the rotating shaft 105, since the dirt scraping piece 200 abuts against the surface of the rolling brush 500, during the rotation of the rolling brush 500, the rolling brush 500 generates a friction force with the dirt scraping piece 200 to drive the dirt scraping piece 200 to rotate.

[0055] Combined with Figure 6In an embodiment, the two side plates 103 of the bracket 100 are provided with the rotation shaft 105 on opposite sides, that is, the bracket 100 is provided with two rotation shafts 105, and the two rotation shafts 105 are spaced apart, and the length direction of the scraping member 200 is provided with the mounting hole 201 on both sides, and the rotation shaft 105 is movably assembled in the mounting hole 201 on the same side of the scraping member 200, so as to rotatably assemble the scraping member 200 in the bracket 100. In another embodiment, the two side plates 103 of the bracket 100 can also be connected by a rotation shaft 105, and the rotation shaft 105 penetrates the scraping member 200, so as to rotatably assemble the scraping member 200 in the bracket 100.

[0056] Figure 7 An exploded schematic view of the scraping member 200 is shown. Figure 2 In combination with Figure 7 , the scraping member 200 and the bracket 100 are also connected by the elastic member 600. In the process of rotating the roller brush 500, when the rotating roller brush 500 drives the scraping member 200 to rotate, the scraping member 200 can only reciprocate within a preset angle due to the arrangement of the elastic member 600, so as to form a floating posture, so as to adapt to different types of garbage on the surface of the roller brush 500, and guarantee the cleaning effect of the scraping member 200 on the surface of the roller brush 500.

[0057] Figure 8 An exploded schematic view of the scraping member 200 is shown. Figure 7 In combination with Figure 8 , the scraping member 200 includes the back plate 202, and the top of the two sides of the back plate 202 is provided with the mounting hole 201, so as to rotatably connect the back plate 202 to the rotation shaft 105 of the bracket 100.

[0058] In combination with Figure 7 and Figure 8 , the elastic member 600 can be a spring, one end of which is connected to the back side of the back plate 202, and the other end of which is connected to the partition plate 102. In an embodiment, one end of the elastic member 600 can be clamped or welded to the back side of the back plate 202, and the other end of the elastic member 600 can penetrate the partition plate 102 and abut against a component of the water containing area, so as to guide the deformation of the elastic member 600. In order to improve the elastic support effect of the scraping member 200, the elastic member 600 can be provided with two or more than two intervals. In another embodiment, the other end of the elastic member 600 can also be directly connected to the front side of the partition plate 102.

[0059] In combination with Figure 7 and Figure 8The scraping component 200 also includes a scraper 203, which 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 debris from 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 using 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.

[0060] Figure 9 It shows Figure 3 A schematic diagram of the BB cross-section. Combined with... Figure 9 In order to enable the scraper 200 to swing within a set angle, the bracket 100 of this application is provided with a constraint part 106, and the scraper 200 is provided with a limit part 204. The limit 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.

[0061] Combination Figure 9 The constraint part 106 is provided with an opening, and at least a portion of the limiting part 204 is placed inside the constraint part 106 through the opening. The limiting part 204 is provided with a limiting protrusion 2053. The limiting protrusion 2053 swings back and forth in the middle of the constraint part 106 and is constrained by both sides of the constraint part 106. By limiting the swing amplitude of the limiting protrusion 2053 of the limiting part 204 within the constraint part 106, the swing amplitude of the scraper 200 relative to the bracket 100 is simultaneously limited, thereby ensuring the cleaning effect of the scraper 200 on the surface of the roller brush 500.

[0062] According to one embodiment of this application, 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.

[0063] Figure 10 It shows Figure 6 A magnified diagram of point B. (Combined with...) Figure 6A 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. The first plate 1071, the second plate 1072 and the partition plate 102 are connected in sequence to form the aforementioned constraint part 106. The first plate 1071 can be arranged perpendicularly to the partition plate 102. The second plate 1072 is inclined upward toward the front side of the support 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.

[0064] Figure 11 It shows Figure 8 A magnified diagram of point C. (Combined with...) Figure 11 The scraper 200 is provided with a second hook-shaped structure 205, which 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 upward toward the roller brush 500. The 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 partition. On the front side of the partition plate 102, the fourth plate 2052 is placed on the upper side of the second plate 1072 and has a certain gap with the second plate 1072; 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 achieving the purpose of limiting the swing amplitude of the limiting protrusion 2053 of the limiting part 204, and thus achieving the purpose of controlling the swing amplitude of the scraper 200.

[0065] According to one embodiment of this application, a limiting portion 204 is provided on at least one side of the scraper 200 along its length, and a restraining portion 106 is disposed 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 specific implementation, the limiting portion 204 can be integrally formed on the side of the back plate 202 along its length.

[0066] Figure 12 A schematic diagram of a bracket with a support section is shown. Figure 12The bracket 100 further comprises a support plate 108 which is connected to the front side of the middle part of the partition plate 102 by clamping or integral forming, and the support plate 108 is configured as the support part 101 of the bracket 100.

[0067] In combination with Figure 12 The front side of the support plate 108 of the bracket 100 is provided with a positioning recess 1081, and the sealing member 300 is fitted in the positioning recess 1081 of the front side of the support plate 108 of the bracket 100, and the top surface of the sealing member 300 can be in the same plane as the top surface of the support plate 108.

[0068] Figure 13 The structure diagram of the sealing member in the bracket is shown. Figure 7 In combination with Figure 13 The top of the sealing member 300 is provided with a sealing protrusion 301 which is elastically abutted against the squeegee member 200. Since the squeegee member 200 is reciprocally swung, in the process of reciprocally swinging of the squeegee member 200, by compressing the sealing protrusion 301, the seamless gap between the squeegee member 200 and the support part 101 of the bracket 100 can be ensured, so as to avoid the garbage cleaned from the surface of the roller brush 500 from entering into the bracket 100 through the gap between the squeegee member 200 and the support part 101 of the bracket 100, and affecting the rotation of the squeegee member 200, so as to ensure the cleaning effect on the surface of the roller brush 500. It should be noted that the bottom of the scraper 203 of the squeegee member 200 is always in contact with the sealing protrusion 301 of the sealing member 300 in the process of reciprocally swinging of the squeegee member 200, and only the compression degree of the sealing protrusion 301 is different under different swinging amplitudes of the squeegee member 200.

[0069] In combination with Figure 13 In an embodiment, the sealing protrusion 301 is inclined to the top of the sealing member 300, and the sealing protrusion 301 extends towards the direction of the roller brush 500, so that the sealing protrusion 301 forms a Y-shaped structure with the sealing member 300, so as to block the garbage cleaned from the surface of the roller brush 500. In another embodiment, the sealing protrusion 301 can also be perpendicular to the top of the sealing member 300, or the sealing protrusion 301 extends away from the roller brush 500 (towards the direction of the partition plate 102 of the bracket 100), which can also block the garbage cleaned from the surface of the roller brush 500.

[0070] In combination with Figure 13 The bottom of the sealing member 300 is provided with a plurality of connecting protrusions 302 which are fixedly clamped on the positioning recess 1081 of the front side of the support plate 108. In another embodiment, the sealing member 300 can also be adhered or / and screw-connected on the positioning recess 1081 of the front side of the support plate 108.

[0071] In combination with Figure 12The support part 101 has multiple comb teeth 700 spaced apart on the side facing the roller brush 500. During the operation of the roller brush 500, the debris on the surface of the roller brush 500 will be combed by the multiple comb teeth 700. Combined 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.

[0072] Combination 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, and a plurality of comb teeth 700 are spaced apart on the mounting protrusions 109. The mounting protrusions 109 may protrude from the front side of the support portion 101 and be inclined away from the support portion 101 to improve the combing effect 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 the support portion 101 may have the aforementioned mounting protrusions 109 at both the bottom and top, without limitation.

[0073] In the relevant 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 interference amount can be about 0.4mm to ensure the cleaning effect on the surface of the roller brush 500.

[0074] Combination Figure 6 An inlet 1010 is also provided on the partition plate 102. The inlet 1010 is located below the support part 101 of the bracket 100. The inlet 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.

[0075] Figure 14 A schematic diagram of the structure of the roller brush cleaning device B according to another embodiment of this application is provided. Figure 15 It shows Figure 14 A top-down view. Figure 16 It shows Figure 15 A schematic diagram of the CC cross-section. Combined with... Figures 14-16 The roller brush cleaning device B provided in this application is used to clean the surface of the roller brush 500. The device includes a bracket 100 and a scraper 200. The bracket 100 is provided with a separate support portion 101. The scraper 200 is connected to the bracket 100 and abuts against the surface of the roller brush 500. The bottom of the scraper 200 abuts against the support portion 101.

[0076] The roller brush cleaning device B provided in this application, because 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 the scraper 200 abuts against the support 101, and the support 101 is separate from the bracket 100, the support 101 can rotate synchronously with the scraper 200. There is no gap between the scraper 200 and the support 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 101, thus affecting the rotation of the scraper 200 and ensuring the normal operation of the roller brush 500. It has excellent practicality. The following is an example... Figure 14 - Appendix Figure 19 Further details of the roller brush cleaning device B are described below.

[0077] Figure 14 The roller brush cleaning device B shown is a type of roller brush cleaning device, similar to roller brush cleaning device A. 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 generally 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.

Figure 18 It shows Figure 17 A schematic diagram of the structure of the cleaning component in the middle. Figure 19 It shows Figure 17 A schematic diagram of the scraper's structure. (Combined with...) Figures 17-19 The scraper 200 also includes a clamping portion 206, which is spaced above the support portion 101. 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 bracket 100 forms a sealed structure to prevent debris cleaned from the surface of the roller brush 500 from entering the bracket 100 through the gap between the clamping portion 206 and the support portion 101. In addition, 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.

[0079] Combination Figure 18 as well as Figure 19In an embodiment, a plurality of connection columns 207 are arranged at intervals between the clamping portion 206 and the support portion 101, and the scraper 203 is also provided with assembly holes 2031, the connection columns 207 and the assembly holes 2031 are arranged correspondingly, the connection columns 207 are inserted into the corresponding assembly holes 2031 to limit the displacement of the scraper 203, so as to guarantee the reliability of the assembly of the scraper 203 between the clamping portion 206 and the support portion 101 of the dirt scraping piece 200.

[0080] In an embodiment, the clamping portion 206 and the support portion 101 of the dirt scraping piece 200 can be integrally formed with the scraper 203. In a specific implementation, the scraper 203 of the dirt scraping piece 200 can be made of metal, and other structures of the dirt scraping piece 200 can be made of plastic, and the other structures of the dirt scraping piece 200 are integrally formed with the scraper 203. In another embodiment, the clamping portion 206 and the support portion 101 of the dirt scraping piece 200 can also be connected with the scraper 203 through bolts or other connecting members, which is not limited herein.

[0081] In combination with Figure 17 and Figure 18 , the support portion 101 is also a plate-shaped structure, which is placed between the two side plates 103 of the bracket 100 and swings back and forth between the two side plates 103. Under the action of the elastic member 600, the side portion of the support portion 101 away from the roller brush 500 (the back side of the support portion 101) has a certain gap with the partition plate 102 of the bracket 100, and the side portion of the support portion 101 towards the roller brush 500 (the front side of the support portion 101) is provided with a plurality of comb teeth 700 at intervals. In the process of operation of the roller brush 500, the garbage on the surface of the roller brush 500 can be combed by the plurality of comb teeth 700, and then the surface of the roller brush 500 is cleaned by the dirt scraping piece 200, so that the cleaning effect of the surface of the roller brush 500 can be further improved.

[0082] From the above, the main difference between the roller brush cleaning device A and the roller brush cleaning device B provided in the application is that the dirt scraping piece 200 in the roller brush cleaning device A is separated from the support portion 101, and the gap between the two is filled by the sealing member 300. The dirt scraping piece 200 in the roller brush cleaning device B is integrated with the support portion 101, so the sealing member 300 in the roller brush cleaning device A can be cancelled.

[0083] Based on the same inventive concept, the application further provides a cleaning device, which comprises the above-mentioned roller brush cleaning device.

[0084] The cleaning device with the above-mentioned roller brush cleaning device can guarantee the cleaning effect of the cleaning device and the normal operation of the roller brush. The cleaning device can be a sweeping robot, a scrubber or a mop, etc.
