[0037] Figure 1 A schematic diagram of a roller brush system according to an embodiment of the utility model; Figure 2 for Figure 1 An exploded view of the roller brush system shown; Figure 3 for Figure 1 Another exploded view of the roller brush system is shown. Figure 1-Figure 3As shown, the roller brush system includes a shell 1, a cover 2, a main brush assembly 3 and a driving assembly 4. The shell 1 and the cover 2 are detachably connected, and the two enclose a receiving cavity for accommodating the main brush assembly 3; the main brush assembly 3 includes a bracket 31, a rotating shaft 32 and a roller brush 33, one end of the rotating shaft 32 passes through the bracket 31 and is rotatably connected to the bracket 31, the other end of the rotating shaft 32 is a free end, and the roller brush 33 is fixed to the circumference of the rotating shaft 32; the inner wall of the shell 1 is provided with a first placement groove 11, the inner wall of the cover 2 is provided with a second placement groove 21, and the first placement groove 11 is arranged opposite to the second placement groove 21 , the two enclose a receiving groove for accommodating the bracket 31; a fixing groove 12 is provided on the inner wall of the shell 1, and a limiting plate 22 is fixed on the inner wall of the cover body 2. When the cover body 2 is connected to the shell 1, the limiting plate 22 is inserted into the fixing groove 12 and abuts against the bracket 31, and the bracket 31 abuts against the inner wall of the receiving groove; a dust suction port 23 is provided through the cover body 2, and when the main brush assembly 3 is installed in the accommodating cavity, part of the roller brush 33 is exposed from the dust suction port 23; a connecting hole 13 is provided on the end surface of the shell 1 close to the bracket 31, and the output end of the driving assembly 4 passes through the connecting hole 13 and is drivingly connected to the rotating shaft 32.
[0038] When assembling, first align the bracket 31 with the first placement groove 11 in the shell body 1, place the main brush assembly 3 in the shell body 1, and place the bracket 31 in the first placement groove 11, then align the limiting plate 22 in the cover body 2 with the fixing groove 12 in the shell body 1, and connect the cover body 2 with the shell body 1, so that the bracket 31 is inserted into the second placement groove 21 in the cover body 2, and the accommodating groove enclosed by the first placement groove 11 and the second placement groove 21 constrains the longitudinal position of the bracket 31. At the same time, the limiting plate 22 is inserted into the fixing groove 12 and abuts against the bracket 31. Under the abutting action of the limiting plate 22, the bracket 31 further abuts against the side wall of the accommodating groove. Finally, the bracket 31 is constrained by the circumferential inner wall of the accommodating groove in the longitudinal direction, and is clamped and restricted by the limiting plate 22 and the side wall of the accommodating groove in the extending direction of the rotating shaft 32. The clamping force of the limiting plate 22 and the side wall of the accommodating groove on the bracket 31 is sufficient to support the gravity of the main brush assembly 3 itself, so that the position of the main brush assembly 3 in the accommodating cavity is fixed. After the main brush assembly 3 is installed, the output end of the driving assembly 4 passes through the connecting hole 13 penetrating the housing 1 and is drivingly connected to the rotating shaft 32 .
[0039] When in use, the roller brush system is installed inside the sweeper, and the drive assembly 4 is started. The rotating shaft 32 rotates under the drive of the drive assembly 4, thereby driving the circumferential roller brush 33 to rotate accordingly. The roller brush 33 exposes the dust suction port 23 to clean the debris and hair on the ground. The hair is entangled with the roller brush 33 and moves toward the free end as the roller brush 33 rotates, and finally comes out from the free end, and is then sucked into the dust storage box under the suction force of the fan inside the sweeper.
[0040] With the roller brush system of the present invention, a bracket 31 is provided at one end of the roller brush 33 and the other end is a free end. The bracket 31 is limited by the accommodating groove in the longitudinal direction and is clamped and constrained by the limiting plate 22 and the side wall of the accommodating groove in the extending direction of the roller brush 33, so that the position of the main brush assembly 3 is fixed. The hair entangled on the roller brush 33 moves toward the free end as the roller brush 33 rotates and finally escapes through the free end. There is no need for manual regular cleaning, which saves time and manpower.
[0041] like Figure 1-Figure 3 As shown, in this embodiment, the cross-sectional profiles of the housing 1 and the cover 2 are both semicircular as a whole, and when the two are connected, they enclose a nearly cylindrical accommodating cavity. Figure 2 As shown, a first placement groove 11 is provided on the inner wall of the housing 1 near the left end surface, and a fixing groove 12 is provided adjacent to the first placement groove 11. The depth of the fixing groove 12 is greater than that of the first placement groove 11, and the fixing groove 12 is close to the left end surface of the housing 1. Correspondingly, Figure 3 The inner wall of the middle cover 2 is provided with a second placement groove 21 at a position corresponding to the first placement groove 11, and a limiting plate 22 is fixed at a position corresponding to the fixing groove 12. The size of the bracket 31 matches the size of the receiving groove enclosed by the first placement groove 11 and the second placement groove 21, so that the bracket 31 can be placed in the receiving groove and constrained by the receiving groove. After the limiting plate 22 is inserted into the fixing groove 12, it can closely abut the bracket 31 and make the bracket 31 closely abut the side wall of the receiving groove, thereby cooperating to fix the bracket 31. Figure 2 As shown, a dust suction port 23 exposing a roller brush 33 is opened through the center of the cover body 2, and a connecting hole 13 is opened through the left end face of the shell 1. The output end of the driving component 4 can pass through the connecting hole 13 and be driven and connected to the rotating shaft 32. The shape of the limiting plate 22 can avoid the axial position of the connecting hole 13, and will not cause inconvenience to the connection between the output end of the driving component 4 and the rotating shaft 32. Figure 2 The left end of the middle roller brush 33 is provided with a bracket 31, and the right end is a free end. The hair wound around the roller brush 33 finally escapes from the roller brush 33 through the right end of the roller brush 33. According to the actual application, the specific shape and size of the shell 1 and the cover 2 can be adjusted according to the needs of the main brush assembly 3, the position of the first placement groove 11 in the shell 1 and the position of the second placement groove 21 in the cover 2 can be matched and adjusted, the setting positions of the fixing groove 12 and the limiting plate 22 can be matched and adjusted, and the driving assembly 4 can use any driving structure, as long as the bracket 31 can be fixed in position with the help of the accommodating groove and the limiting plate 22, and the driving assembly 4 can drive the rotating shaft 32 to rotate, thereby driving the roller brush 33 to rotate, and further allowing the hair wound around the roller brush 33 to escape from the free end.
[0042] Figure 4 for Figure 3 The exploded view shows a schematic diagram of a state in which the output shaft in the reduction box of the drive assembly is retracted into the reduction box; Figure 5 for Figure 4 The output shaft of the reduction gearbox is shown in the figure. Figure 4 and Figure 5 As shown, optionally, the driving assembly 4 includes a motor 41 and a reduction box 42. An input shaft 421 and an output shaft 422 are arranged in the reduction box 42. An input gear 423 is sleeved on the input shaft 421, and an output gear 424 is sleeved on the output shaft 422. The output gear 424 is meshed and connected with the input gear 423. The input shaft 421 is drivingly connected with the output end of the motor 41. The output shaft 422 can extend or retract from the reduction box 42 along the output gear 424. When the output shaft 422 extends from the reduction box 42 along the output gear 424, it is connected to the rotating shaft 32 and drives the rotating shaft 32 to rotate. The output shaft 422 can be extended and retracted in the output gear 424, so that when the main brush assembly 3 is installed in the housing 1, the output shaft 422 can be retracted, so that the main brush assembly 3 has enough space to be placed, and does not need to be placed in the housing 1 at an angle, which is convenient for installation.
[0043] like Figure 2 , Figure 4 and Figure 5 As shown, during the installation of the main brush assembly 3, the output shaft 422 of the reduction box 42 is retracted into the reduction box 42, so that part of the space in the housing 1 can be released. When the main brush assembly 3 is placed in the housing 1, it can be placed vertically without interfering with the output shaft 422. When cleaning is required, the output shaft 422 is extended out of the reduction box 42 and connected to the rotating shaft 32, thereby driving the rotating shaft 32 to rotate, and then driving the roller brush 33 to rotate for cleaning. The output shaft 422 of the reduction box 42 is the output end of the drive assembly 4.
[0044] Figure 6 for Figure 4 An exploded view of the reduction gearbox shown; Figure 7 for Figure 6 The schematic diagram of the output shaft and output gear of the reduction gearbox is shown in FIG. Figure 6 and Figure 7 As shown, optionally, the output shaft 422 is threadedly connected to the output gear 424; a damper 425 is also provided in the reduction box 42, one end of the damper 425 is fixedly connected to the inner wall of the reduction box 42, and the other end interferes with the output shaft 422; a driving block 426 is fixed to the inner wall of the output gear 424, and a driven arm 427 is fixed to the outer wall of the output shaft 422. When the output shaft 422 extends out of the reduction box 42 and is connected to the rotating shaft 32, the driven arm 427 abuts against the driving block 426. This arrangement makes the extension and retraction structure of the output shaft 422 simple and easy to assemble.
[0045] like Figure 6 and Figure 7As shown, in this embodiment, the outer wall of the output shaft 422 is provided with an outer thread 431, and the inner wall of the output gear 424 is provided with an inner thread 430, and the two are threadedly connected by means of the inner thread 430 and the outer thread 431. Two driving blocks 426 are fixed at intervals at one end of the inner thread 430 of the output gear 424 away from the housing 1, and two driven arms 427 are fixed at intervals at one end of the output shaft 422 away from the housing 1. When the output shaft 422 is screwed into the output gear 424 toward the housing 1 to the position of the driving blocks 426 by means of the outer thread 431 and the inner thread 430, the two driven arms 427 are respectively in contact with the two driving blocks 426. Figure 6 The left end of the middle damper 425 is fixed to the inner wall of the reduction box 42 and is coaxially arranged with the output shaft 422. A groove is provided on the end surface of the output shaft 422 facing the damper 425, and the groove extends a distance away from the damper 425. The right end of the damper 425 is inserted into the groove and interferes with the inner wall of the groove. The motor 41 rotates forward, driving its output end and the input shaft 421 of the reduction box 42 that is drivingly connected to the output end to rotate, thereby driving the input gear 423 sleeved with the input shaft 421 to rotate synchronously. The input gear 423 is meshed and connected with the output gear 424 through the transmission gear 428, thereby driving the output gear 424 to rotate. The output gear 424 is threadedly connected with the output shaft 422 of the reduction box 42. At the same time, the output shaft 422 interferes with the damper 425. Under the interference of the damper 425, the output shaft 422 does not rotate synchronously with the output gear 424, but generates a relative rotation to the output gear 424. 24 rotates, and then with the cooperation of the internal thread 430 and the external thread 431, the output shaft 422 produces axial movement toward the direction of the shell 1, and finally extends out of the reduction box 42, and is connected with the coaxially arranged rotating shaft 32. When the output shaft 422 is connected to the rotating shaft 32, the driving block 426 on the inner wall of the output gear 424 abuts against the driven arm 427 on the outer wall of the output shaft 422, so that the output shaft 422 will not continue to move toward the direction of the shell 1, but will rotate synchronously with the output gear 424, thereby driving the rotating shaft 32 and the roller brush 33 circumferentially of the rotating shaft 32 to rotate, thereby realizing the cleaning work of the roller brush 33. When the cleaning work is completed, the motor 41 is reversed, and its output end and the input shaft 421 of the reduction box 42 connected to the output end are reversed accordingly, thereby driving the input gear 423 mounted on the input shaft 421 to reverse synchronously, and further driving the output gear 424 to reverse. Under the interference of the damper 425, the output shaft 422 does not reverse synchronously with the output gear 424, but rotates relative to the output gear 424. Then, under the cooperation of the internal thread 430 and the external thread 431, the output shaft 422 moves axially away from the housing 1, thereby releasing the connection with the rotating shaft 32 and finally retracting the reduction box 42. After the output shaft 422 retracts into the reduction box 42, the motor 41 is turned off. Figure 6As shown, the input gear 423 is meshed with the output gear 424 by means of two meshing transmission gears 428. According to the actual application, the number of transmission gears 428 can be adjusted, and the specific position and number of the driving block 426 on the inner wall of the output gear 424 and the position and number of the driven arm 427 on the outer wall of the output shaft 422 can be matched and adjusted. The damper 425 is a mature existing technology, and its specific structure and working principle are not repeated here.
[0046] Optionally, the outer wall of one end of the output shaft 422 extending out of the reduction box 42 is fixed with multiple clamping strips 429 at intervals; the end surface of one end of the rotating shaft 32 passing through the bracket 31 is provided with a placement groove, and the inner wall of the placement groove is provided with multiple clamping grooves (not shown) at intervals, and the multiple clamping grooves correspond to the multiple clamping strips 429 one by one and are clamped in cooperation. With the cooperation of the clamping strips 429 and the clamping grooves, the connection between the output shaft 422 of the reduction box 42 and the rotating shaft 32 is achieved, and the structure is simple and easy to operate.
[0047] like Figure 7 As shown, in this embodiment, a plurality of snap-in strips 429 are evenly arranged on the outer wall of the right end of the output shaft 422 in the circumferential direction. Correspondingly, Figure 5 The middle rotating shaft 32 passes through the left end face of the bracket 31 and is provided with a placement groove. The placement groove is provided with a plurality of snap-in grooves corresponding to the positions of the snap-in strips 429 in the circumferential direction. After the output shaft 422 extends out of the reduction box 42 under the driving action of the motor 41, it is inserted into the placement groove, and the plurality of snap-in strips 429 on the output shaft 422 are snap-in one by one with the plurality of snap-in grooves. According to the actual application, the number and specific distribution of the snap-in grooves and the snap-in strips 429 can be matched and adjusted.
[0048] Optionally, platforms 14 are respectively provided at both ends of the first placement groove 11 in the extension direction, and when the main brush assembly 3 is installed in the accommodating cavity, the bracket 31 overlaps the platform 14, and the cover body 2 abuts against the bracket 31. The height of the platform 14 is adjusted so that after the bracket 31 overlaps the platform 14, the rotating shaft 32 and the connecting hole 13 of the housing 1 can be coaxially arranged, thereby ensuring that after the output end of the driving assembly 4 passes through the connecting hole 13, it can match the position of the rotating shaft 32 and realize the driving connection.
[0049] If the shape and size of the bracket 31 deviate, the rotating shaft 32 rotatably connected to the bracket 31 may not be coaxially arranged with the connecting hole 13 of the housing 1 after the bracket 31 is placed in the receiving groove, and the output end of the driving assembly 4 cannot be smoothly driven and connected with the rotating shaft 32 after passing through the connecting hole 13. The bracket 31 is overlapped on the platform 14, and a gap is maintained between the bracket 31 and the inner wall of the first placement groove 11, which not only ensures that the height of the rotating shaft 32 can match the connecting hole 13 after the bracket 31 is overlapped with the platform 14, but also ensures that the bracket 31 will not interfere with the inner wall of the first placement groove 11 when there is a shape or size deviation. At the same time, the cover 2 abuts against the bracket 31 to further limit the bracket 31, thereby ensuring that the positions of the rotating shaft 32 and the connecting hole 13 always correspond. According to actual application conditions, the setting height of the platform 14 is adjusted according to the opening height of the connecting hole 13 on the housing 1 and its relative height to the bracket 31 and the rotating shaft 32.
[0050] Optionally, the distance between the side surface of the bracket 31 facing the roller brush 33 and the roller brush 33 gradually increases in the direction away from the rotation shaft 32. This arrangement ensures that there is a certain gap between the bracket 31 and the roller brush 33, preventing the roller brush 33 from interfering with the bracket 31 during the rotation of the rotation shaft 32.
[0051] like Figure 4 and Figure 5 As shown, the left end surface of the bracket 31 is a plane, and the right end surface is inclined from the center position connected to the rotating shaft 32 to the circumferential direction in the direction away from the roller brush 33, so that the gap between the bracket 31 and the roller brush 33 gradually increases from the center to the edge. According to the actual application, the inclination angle of the surface of the bracket 31 facing the roller brush 33 can be appropriately adjusted.
[0052] Optionally, the housing 1 is provided with an outlet on one side near the free end of the rotating shaft 32, and the outlet is connected to a delivery pipe 15, which is used to be connected to a dust storage box in the sweeper. The hair wound around the roller brush 33 continuously moves toward the free end thereof during the rotation of the roller brush 33. The outlet is provided at a position of the housing 1 near the free end of the roller brush 33, and the hair coming out of the free end of the roller brush 33 can be smoothly sucked into the dust storage box through the outlet and the delivery pipe 15 under the suction of the fan inside the sweeper, thereby completing the collection of the hair.
[0053] like Figure 2 As shown, a bracket 31 is provided at the left end of the roller brush 33, and the right end is a free end. Correspondingly, an outlet is opened through the side wall of the shell 1 near the right end, and is connected to a bent conveying pipe 15. The end of the conveying pipe 15 away from the shell 1 is connected to the dust storage box in the sweeper.
[0054] Optionally, the housing 1 is provided with a plurality of snap holes 16, and the cover 2 is provided with a plurality of snap buckles 24, which correspond to and are snap-connected with the plurality of snap holes 16. The housing 1 and the cover 2 are detachably connected by the cooperation of the snap buckles 24 and the snap holes 16, and the structure is simple and easy to assemble.
[0055] like Figure 3 As shown, two buckles 24 are arranged at intervals on the upper edge of the cover 2, and three buckles 24 are arranged at intervals on the lower edge. Correspondingly, two clamping holes 16 are arranged at intervals on the upper edge of the shell 1, and three clamping holes 16 are arranged at intervals on the lower edge. When the cover 2 is connected to the shell 1, the buckles 24 are inserted into the corresponding clamping holes 16 to achieve the clamping connection between the cover 2 and the shell 1. According to the actual application, the setting positions and quantities of the buckles 24 and the clamping holes 16 can be matched and adjusted.
[0056] Optionally, a guide plate 25 is provided on the side of the cover body 2 facing away from the shell 1, and the guide plate 25 extends away from the shell 1 and toward the dust suction port 23. During the cleaning operation, if the sweeper encounters an obstacle, the inclined surface of the guide plate 25 can provide a guiding effect to help the sweeper to smoothly pass the obstacle.
[0057] like Figure 2 As shown, the cover 2 faces away from the side of the housing 1, that is, Figure 2 There are four guide plates 25 on the upper surface of the middle cover body 2. The four guide plates 25 are spaced apart along the length direction of the dust suction port 23. Each guide plate 25 is tilted toward the dust suction port 23. When the sweeper moves, the inclined surface of the guide plate 25 faces the moving direction.
[0058] The utility model also provides a sweeping machine, comprising a shell and a roller brush system as described in any one of the above embodiments, wherein the roller brush system is installed in the shell.
[0059] With the sweeping machine of the present invention, a bracket 31 is provided at one end of the roller brush 33 and the other end is a free end. The bracket 31 is limited by the accommodating groove in the longitudinal direction and is clamped and constrained by the limiting plate 22 and the side wall of the accommodating groove in the extending direction of the roller brush 33, so that the position of the main brush assembly 3 is fixed. The hair entangled on the roller brush 33 moves toward the free end as the roller brush 33 rotates and finally escapes through the free end. There is no need for manual regular cleaning, which saves time and manpower.
