[0052] The roller brush cleaning device A provided by the present application is used to clean the surface of the roller brush 500. The device includes a bracket 100, a scraping member 200, and a sealing member 300. Among them, the bracket 100 is provided with a supporting portion 101. The scraping member 200 is connected to the bracket 100. At least part of the gap of the scraping member 200 is placed on the supporting portion 101. The scraping member 200 abuts against the surface of the roller brush 500. The sealing member 300 is placed on the supporting portion 101, and at least part of the sealing member 300 elastically abuts against the scraping member 200. Figure 1 -Attached Figure 13 The specific details of the roller brush cleaning device A will be further described.

[0053] Combined with Figure 1 And Figure 2, according to an embodiment of the present application, the rotary brush 500 is rotatably mounted on the base 400 of the cleaning device. The bracket 100 can be integrated on the base 400 of the cleaning device, and the bracket 100 and the rotary brush 500 are spaced apart. For the convenience of description, the side of the bracket 100 facing the rotary brush 500 is defined as the front side, and the side facing away from the rotary brush 500 is defined as the rear side.

[0054] Figure 6 shows Figure 2 a schematic structural view of the base in Figure 6 . Combining

[0055] , the bracket 100 includes a partition plate 102 and two side plates 103. The partition plate 102 is placed inside the base 400 to divide the base 400 into a water storage area and an installation area for the rotary brush 500. The two side plates 103 are oppositely arranged on both sides of the front side of the partition plate 102. The side plates 103 of the bracket 100 are provided with receiving grooves 104 that match at least a part of the circumferential surface of the rotary brush 500. At least a part of the circumferential surface of the rotary brush 500 rotates in the receiving grooves 104 to clean the ground.

[0055] Combining Figure 6 , a rotating shaft 105 is provided on the bracket 100, and the dirt scraping member 200 is rotatably connected to the rotating shaft 105. Since the dirt scraping member 200 abuts against the surface of the rotary brush 500, during the rotation of the rotary brush 500, a frictional force is generated between the rotating rotary brush 500 and the dirt scraping member 200 to drive the dirt scraping member 200 to rotate.

[0056] Combining Figure 6 , in one embodiment, the above-mentioned rotating shafts 105 are provided on both opposite sides of the two side plates 103 of the bracket 100, that is, the bracket 100 is configured with two rotating shafts 105, and there is a distance between the two rotating shafts 105. Mounting holes 201 are respectively provided on both sides in the length direction of the dirt scraping member 200, and the rotating shafts 105 are movably assembled in the mounting holes 201 on the same side of the dirt scraping member 200 to rotatably assemble the dirt 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 rotating shaft 105, and the rotating shaft 105 penetrates through the dirt scraping member 200 to rotatably assemble the dirt scraping member 200 in the bracket 100.

[0057] Figure 7 shows Figure 2 an exploded schematic view of Figure 7 . Combining , the dirt scraping member 200 and the bracket 100 are also connected by an elastic member 600. During the rotation of the rotary brush 500, when the rotating rotary brush 500 drives the dirt scraping member 200 to rotate, due to the setting of the elastic member 600, the dirt scraping member 200 can only swing reciprocally within a preset angle to form a floating posture to adapt to different types of garbage on the surface of the rotary brush 500 and ensure the cleaning effect of the dirt scraping member 200 on the surface of the rotary brush 500.

[0058] Figure 8 shows Figure 7 a schematic structural diagram of the scraping member in Figure 8 , the scraping member 200 includes a back plate 202, and the mounting holes 201 are provided at the tops on both sides of the back plate 202, so that the back plate 202 is rotatably connected to the rotating shaft 105 of the bracket 100.

[0059] Combined with Figure 7 and Figure 8 , the elastic member 600 can be a spring, one end of which is connected to the rear side of the back plate 202, and the other end is connected to the partition plate 102. Specifically, in one embodiment, one end of the elastic member 600 can be clamped or welded to the rear side of the back plate 202, and the other end of the elastic member 600 can pass through the partition plate 102 and abut against a certain component in the water storage area to provide guidance for the deformation of the elastic member 600. In order to improve the elastic support effect on the scraping member 200, more than two elastic members 600 can be arranged at 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.

[0060] Combined with Figure 7 and Figure 8 , the scraping member 200 further includes a scraper 203, and the scraper 203 is connected to the front side of the bottom of the back plate 202, so that the scraping member 200 is generally L-shaped, and the front side of the scraper 203 preferably faces below the central axis of the roller brush 500 to effectively clean the garbage 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 through a connecting member such as a screw. In another embodiment, the scraper 203 can also be integrally formed with the back plate 202, as long as it is ensured that the scraper 203 is fixedly connected to the back plate 202 and rotates synchronously, and the connection method between the two is not limited herein.

[0061] Figure 9 shows Figure 3 a schematic cross-sectional view taken along line B-B in Figure 9 . In order to enable the scraping member 200 to swing within a set angle, the bracket 100 of the present application is provided with a constraint portion 106, and the scraping member 200 is provided with a limiting portion 204. The limiting portion 204 swings back and forth within the constraint portion 106 at a set angle to ensure the cleaning effect of the scraping member 200 on the surface of the roller brush 500.

[0062] Combined with Figure 9, the restraining part 106 is provided with an opening, at least a part of the limiting part 204 is placed inside the restraining part 106 through the opening, the limiting part 204 is provided with a limiting convex part 2053, and the limiting convex part 2053 swings back and forth in the middle of the restraining part 106 and is restrained by both sides of the restraining part 106, so as to synchronously limit the swinging amplitude of the scraping part 200 relative to the bracket 100 by restricting the swinging amplitude of the limiting convex part 2053 of the limiting part 204 inside the restraining part 106, and ensure the cleaning effect of the scraping part 200 on the surface of the roller brush 500.

[0063] In an embodiment of the present application, the distance from the limiting convex part 2053 to the rotating shaft 105 needs to be greater than the distance from both sides of the restraining part 106 to the rotating shaft 105 and less than the distance from the middle of the restraining part 106 to the rotating shaft 105, so that the limiting convex part 2053 swings back and forth in the middle of the restraining part 106 and is restrained by both sides of the restraining part 106. It should be noted that the distance from the restraining part 106 to the rotating shaft 105 is variable or can be fixed, but it must be ensured that the distance from the restraining part 106 to the rotating shaft meets the above settings.

[0064] Figure 10 shows Figure 6 The enlarged schematic view at position B of. Combining 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 placed 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 body 1071 and a second plate body 1072. The first plate body 1071, the second plate body 1072 and the partition plate 102 are connected in sequence to form the above-mentioned restraining part 106. Among them, the first plate body 1071 can be arranged perpendicular to the partition plate 102, and the second plate body 1072 is inclined upward toward the front side of the bracket 100. The first plate body 1071 is configured as the middle part of the restraining part, and the partition plate 102 and the second plate body 1072 are configured as both sides of the restraining part. The limiting convex part 2053 of the limiting part 204 moves back and forth inside the first plate body 1071 and is restrained by the partition plate 102 and the second plate body 1072 to limit the swinging amplitude of the limiting convex part 2053 of the limiting part 204.

[0065] Figure 11 shows Figure 8 The enlarged schematic view at position C of. Combining Figure 11, the scraping member 200 is provided with a second hook-like structure 205. The second hook-like structure 205 includes a third plate body 2051 and a fourth plate body 2052. The fourth plate body 2052 is connected to the front side of the bottom of the third plate body 2051 and is inclined upward toward the roller brush 500. The limiting convex portion 2053 is disposed at the bottom of the connection between the fourth plate body 2052 and the third plate body 2051. Under the condition that the scraping member 200 does not rotate, the third plate body 2051 is attached to the front side of the partition plate 102, and the fourth plate body 2052 is disposed above the second plate body 1072 and has a certain gap from the second plate body 1072; under the condition that the scraping member 200 rotates, the limiting convex portion 2053 rotates above the first plate body 1071 and is limited by the second plate body 1072 and the partition plate 102, that is, the purpose of limiting the swing amplitude of the limiting convex portion 2053 of the limiting portion 204 is achieved, and then the purpose of controlling the swing amplitude of the scraping member 200 is achieved.

[0066] According to an embodiment of the present application, a limiting portion 204 is provided on at least one side in the length direction of the scraping member 200, and the constraining portion 106 is disposed between the bracket 100 and the scraping member 200. The fact that a limiting portion 204 is provided on at least one side in the length direction of the scraping member 200 means that the above-mentioned limiting portions 204 can be provided on both sides in the length direction of the scraping member 200, or only on one side in the length direction of the scraping member 200. Specifically, in implementation, the limiting portion 204 can be integrally formed on the side portion in the length direction of the back plate 202.

[0067] Figure 12 The structural schematic diagram of the bracket with a support portion is shown. Combining Figure 12 , the bracket 100 further includes a support plate 108, which can be connected to the front side of the middle part of the partition plate 102 by clamping or integrally formed, and the support plate 108 is configured as the support portion 101 of the bracket 100.

[0069] Figure 13 The structural schematic diagram of the sealing member in Figure 7 is shown. Combining Figure 13, a sealing convex part 301 is arranged on the top of the seal 300, and the sealing convex part 301 elastically abuts against the dirt scraping part 200. Since the dirt scraping part 200 swings back and forth, during the reciprocating swing of the dirt scraping part 200, by compressing the sealing convex part 301, it can ensure that there is no gap between the dirt scraping part 200 and the supporting part 101 of the bracket 100, so as to prevent the garbage cleaned from the surface of the rolling brush 500 from entering the bracket 100 through the gap between the dirt scraping part 200 and the supporting part 101 of the bracket 100, which affects the rotation of the dirt scraping part 200, so as to ensure the cleaning effect on the surface of the rolling brush 500. It should be noted that during the reciprocating swing of the dirt scraping part 200, the bottom of the scraper 203 of the dirt scraping part 200 always contacts the sealing convex part 301 of the seal 300, but the compression degree of the sealing convex part 301 is different under different swing amplitudes of the dirt scraping part 200.

[0070] Combined with Figure 13 , in an embodiment, the sealing convex part 301 is inclined to the top of the seal 300, and the sealing convex part 301 extends towards the direction of the rolling brush 500, so that the sealing convex part 301 and the seal 300 form a Y-shaped structure to block the garbage cleaned from the surface of the rolling brush 500. In another embodiment, the sealing convex part 301 can also be perpendicular to the top of the seal 300, or the sealing convex part 301 extends away from the rolling brush 500 (towards the partition plate 102 of the bracket 100), and it can also block the garbage cleaned from the surface of the rolling brush 500.

In another embodiment, the seal 300 can also be bonded or / and screwed to the positioning recess 1081 on the front side of the support plate 108.

[0072] Combined with Figure 12 , a plurality of comb teeth 700 are arranged at intervals on the side of the supporting part 101 facing the rolling brush 500. During the operation of the rolling brush 500, the garbage on the surface of the rolling brush 500 will be combed by the plurality of comb teeth 700, and then combined with the cleaning of the surface of the rolling brush 500 by the dirt scraping part 200, which can further improve the cleaning effect on the surface of the rolling brush 500.

[0073] Combined with Figure 12, in one embodiment, mounting protrusions 109 are provided on the bottom side and / or the top side of the side of the supporting portion 101 facing the roller brush 500, and a plurality of comb teeth 700 are arranged at intervals on the mounting protrusions 109. The mounting protrusions 109 can protrude from the front side of the supporting portion 101 and incline away from the supporting portion 101, so as to improve the combing effect on the garbage on the surface of the roller brush 500. In another embodiment, the mounting protrusions 109 can also be placed at the bottom of the supporting portion 101, or the mounting protrusions 109 are provided on both the bottom and the top of the supporting portion 101, which is not limited herein.

[0074] In the related art, the roller brush 500 includes a brush body and a mop on the surface of the brush body. A plurality of comb teeth 700 are tangent to the brush body of the roller brush 500, or a plurality of comb teeth 700 are tangent to the concentric circles of the roller brush 500. When the cleaning device is working, a certain interference amount exists between the plurality of comb teeth 700 and the mop on the roller brush 500, and the interference amount can be about 0.4 mm to ensure the cleaning effect on the surface of the roller brush 500.

[0075] Combined with Figure 6 , a suction port 1010 is further provided on the partition plate 102. The suction port 1010 is located below the supporting portion 101 of the bracket 100, and the suction port 1010 is communicated with the dirt collection box of the cleaning device. A blower is also provided in the cleaning device. Under the action of the blower, a negative pressure is formed inside the dirt collection box, and the garbage cleaned from the roller brush 500 by the cleaning device is sucked into the dirt collection box for collection to ensure the cleaning effect of the roller brush 500.

[0081] In one embodiment, the clamping portion 206 and the supporting portion 101 of the scraping member 200 can be integrally formed with the scraping blade 203. Specifically, when implemented, the scraping blade 203 of the scraping member 200 can be made of metal, and other structures of the scraping member 200 can be made of plastic, and other structures of the scraping member 200 are integrally formed with the scraping blade 203. In another embodiment, the clamping portion 206 and the supporting portion 101 of the scraping member 200 can also be connected to the scraping blade 203 through connecting members such as bolts, which is not limited herein.

[0082] Combined with Figure 17 and Figure 18 , the supporting portion 101 is also a plate-like 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, there is a certain gap between the side portion of the supporting portion 101 facing away from the rolling brush 500 (the rear side of the supporting portion 101) and the partition plate 102 of the bracket 100. A plurality of comb teeth 700 are arranged at intervals on the side portion of the supporting portion 101 facing the rolling brush 500 (the front side of the supporting portion 101). During the operation of the rolling brush 500, the garbage on the surface of the rolling brush 500 will be combed by the plurality of comb teeth 700, and combined with the cleaning of the surface of the rolling brush 500 by the scraping member 200, the cleaning effect of the surface of the rolling brush 500 can be further improved.

[0083] As can be seen from the above, the main difference between the rolling brush cleaning device A and the rolling brush cleaning device B provided in the present application is that: the scraping member 200 in the rolling brush cleaning device A is spaced apart from the supporting portion 101, and the gap between the two is filled with the sealing member 300. The scraping member 200 in the rolling brush cleaning device B is integrated with the supporting portion 101. Therefore, the sealing member 300 in the rolling brush cleaning device A can be cancelled.

[0084] Based on the same inventive concept, the present application also provides a cleaning device, which includes the above rolling brush cleaning device.

[0085] The cleaning device having the above rolling brush cleaning device can ensure the cleaning effect of the cleaning device and the normal operation of the rolling brush. Among them, the cleaning device can be a sweeping robot, a floor washer or a mopping machine, etc.

[0086] Based on the same inventive concept, the present application also provides a cleaning system, which includes a cleaning base station and the above-mentioned cleaning device that are used in cooperation with each other.
