In combination with Figures 1-5 , the roller brush cleaning device A provided by the present application is used for cleaning the surface of the roller 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 roller brush 500; the sealing piece 300 is arranged on the supporting part 101, and at least part of the sealing piece 300 elastically abuts against the dirt scraping piece 200.

[0050] The roller brush cleaning device A provided by the present application has the following advantages. Since the dirt scraping piece 200 is connected to the support 100 and abuts against the surface of the roller brush 500, the garbage on the surface of the roller brush 500 can be cleaned by the dirt scraping piece 200 during the operation of the roller brush 500, so as to guarantee the cleaning effect of the cleaning device. 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 sealing piece 300 elastically abuts against the dirt scraping piece 200, 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 roller 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, thereby affecting the rotation of the dirt scraping piece 200, so as to make the roller brush 500 normally operate, and the roller brush cleaning device A has good practicability. Figure 1 -attached Figure 13 , the specific details of the roller brush cleaning device A are further described.

[0051] In combination with Figure 1 and Figure 2According to an embodiment of the present application, the rolling brush 500 is rotatably mounted on the base 400 of the cleaning device, and the support 100 is integrated on the base 400 of the cleaning device, and the support 100 and the rolling brush 500 are arranged in a spaced manner. For the convenience of description, it is defined that the side of the support 100 facing the rolling brush 500 is defined as the front side, and the side facing away from the rolling brush 500 is defined as the back side.

[0052] Figure 6 A structural schematic view of the base in Figure 2 is shown. In combination 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 divide 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 each other on the two sides of the front side of the partition plate 102. The side plate 103 of the support 100 is provided with a receiving groove 104 matching at least part of the circumferential surface of the rolling brush 500. At least part of the circumferential surface of the rolling brush 500 rotates in the receiving groove 104 to clean the ground.

[0053] In combination with Figure 6 , the support 100 is provided with a rotating shaft 105, and the scraping member 200 is rotatably connected to the rotating shaft 105. Since the scraping member 200 abuts against the surface of the rolling brush 500, the rolling brush 500 generates a friction force with the scraping member 200 during rotation to drive the scraping member 200 to rotate.

[0054] In combination with Figure 6 , in an embodiment, the two side plates 103 of the support 100 are each provided with the rotating shaft 105, i.e., the support 100 is provided with two rotating shafts 105, and the two rotating shafts 105 have a spacing therebetween. The scraping member 200 is provided with mounting holes 201 on both sides in the length direction. The rotating shaft 105 is movably assembled in the mounting holes 201 on the same side of the scraping member 200 to rotatably assemble the scraping member 200 in the support 100. In another embodiment, the two side plates 103 of the support 100 can also be connected by a rotating shaft 105. The rotating shaft 105 penetrates the scraping member 200 to rotatably assemble the scraping member 200 in the support 100.

[0055] Figure 7 An exploded schematic view of Figure 2 is shown. In combination with Figure 7 , the scraping member 200 and the support 100 are further connected by an elastic member 600. During rotation of the rolling brush 500, the rolling brush 500 drives the scraping member 200 to rotate. Due to the arrangement of the elastic member 600, the scraping member 200 can only reciprocate within a preset angle to form a floating posture to adapt to different types of garbage on the surface of the rolling brush 500, thereby guaranteeing the cleaning effect of the scraping member 200 on the surface of the rolling brush 500.

[0056] Figure 8 a structure diagram of the scraping member in the Figure 7 is shown, in combination with Figure 8 The scraping member 200 comprises a back plate 202, and the top of both sides of the back plate 202 is provided with the mounting hole 201 described above, so that the back plate 202 is rotatably connected to the rotating shaft 105 of the support 100.

[0057] 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 a specific implementation, 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 pass through the partition plate 102 and abut against a certain 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 elastic members 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.

[0058] In combination with Figure 7 and Figure 8 The scraping member 200 further comprises a scraper 203, which is connected to the front side of the bottom of the back plate 202, so that the scraping member 200 is roughly L-shaped, and the front side of the scraper 203 is preferably directed below the central axis of the rolling brush 500, so as to effectively clean the garbage on the surface of the rolling brush 500. In an embodiment, the scraper 203 can be detachably connected to the bottom of the back plate 202 through a connecting member such as a screw, and 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 with the back plate 202 and rotates synchronously, and the connecting mode of the two is not limited herein.

[0061] According to an embodiment of the present application, the distance from the limiting protrusion 2053 to the rotating shaft 105 is greater than the distance from the two sides of the constraint portion 106 to the rotating shaft 105, and is less than the distance from the middle of the constraint portion 106 to the rotating shaft 105, so that the limiting protrusion 2053 reciprocally swings in the middle of the constraint portion 106 and is constrained by the two sides of the constraint portion 106. It should be noted that the distance from the constraint portion 106 to the rotating shaft 105 is variable or fixed, but it must be ensured that the distance from the constraint portion 106 to the rotating shaft 105 meets the above setting.

[0063] Figure 11 An enlarged schematic view of C of FIG. 1 is shown. Figure 8 Figure 11 ​​The scraping member 200 is provided with a second hook structure 205, which comprises a third plate body 2051 and a fourth plate body 2052 connected to the front side of the bottom of the third plate body 2051 and inclined upward toward the direction of the rolling brush 500. A limiting protrusion 2053 is arranged 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 is not rotated, the third plate body 2051 is attached to the front side of the partition plate 102, and the fourth plate body 2052 is arranged on the upper side of the second plate body 1072 and has a certain gap with the second plate body 1072. Under the condition that the scraping member 200 is rotated, the limiting protrusion 2053 is rotated 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 range of the limiting protrusion 2053 of the limiting portion 204 is achieved, and then the purpose of controlling the swing range of the scraping member 200 is achieved.

In combination with Figure 13The top of the sealing member 300 is provided with a sealing protrusion 301 which elastically abuts against the squeegee member 200. Since the squeegee member 200 reciprocally swings, during the reciprocating swing of the squeegee member 200, the sealing protrusion 301 is compressed to ensure that there is no gap between the squeegee member 200 and the supporting portion 101 of the support 100, so as to avoid the garbage cleaned from the surface of the roller brush 500 from entering the support 100 through the gap between the squeegee member 200 and the supporting portion 101 of the support 100, affecting the rotation of the squeegee member 200, and ensuring the cleaning effect on the surface of the roller brush 500. It should be noted that during the reciprocating swing of the squeegee member 200, 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, and only the compression degree of the sealing protrusion 301 is different under different swing amplitudes of the squeegee member 200.

[0068] In combination Figure 13 In an embodiment, the sealing protrusion 301 is inclined to the top of the sealing member 300 and extends towards the roller brush 500, so that the sealing protrusion 301 and the sealing member 300 form a Y-shaped structure 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 partition plate 102 of the support 100), which can also block the garbage cleaned from the surface of the roller brush 500.

[0070] In combination Figure 12 The supporting portion 101 is provided with a plurality of comb teeth 700 on the side facing the roller brush 500. During the operation of the roller brush 500, the garbage on the surface of the roller brush 500 is combed by the plurality of comb teeth 700, and then the surface of the roller brush 500 is cleaned by the squeegee member 200, which can further improve the cleaning effect on the surface of the roller brush 500.

[0071] In combination Figure 12In one embodiment, a mounting protrusion 109 is provided on the bottom and / or top side of the support portion 101 facing the roller brush 500, and a plurality of comb teeth 700 are spaced apart on the mounting protrusion 109.

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 garbage 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 garbage on the surface of the roller brush 500.

[0078] Combine 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.

[0079] 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. In another embodiment, the clamping portion 206 and the support portion 101 of the dirt scraping piece 200 can also be connected to the scraper 203 through bolts or other connecting members, which is not limited herein.

[0080] In combination with Figure 17 and Figure 18 , the support portion 101 is also a plate-shaped structure, which is arranged 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 toward 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 can be cleaned by the dirt scraping piece 200, so that the cleaning effect of the surface of the roller brush 500 can be further improved.

[0081] As known from the above, the main difference between the roller brush cleaning device A and the roller brush cleaning device B provided in the application lies in 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 that the sealing member 300 in the roller brush cleaning device A can be cancelled.
