[0035] Fig.10 Shown is a schematic structural diagram of a dust-pushing assembly provided in one embodiment of the present application. Fig.11 The present invention provides an embodiment of the present invention. Fig.10 A partial enlarged view of the dust pusher assembly in area G is shown. Fig.12 Shown is a schematic structural diagram of a maintenance cover provided in one embodiment of the present application. Fig.13 The figure is a schematic diagram of the structure of a cleaning robot provided by an embodiment of the present application. Figures 1 to 3 As shown, the dust pusher assembly 10 includes: a support assembly 100, a roller brush assembly 200, a cleaning assembly 300 and a dust box assembly 400.

[0036] like Fig.13As shown, the dust pusher assembly 10 is applied to the cleaning robot 1. The support assembly 100 can be connected to the main body 20 of the cleaning robot 1. Exemplarily, the support assembly 100 can be detachably connected to the main body 20. For example, the support assembly 100 is detachably connected to the main body 20 by bolts. For another example, the support assembly 100 is detachably connected to the main body 20 by a snap-on method.

[0037] The roller brush assembly 200 is rotatably connected to the support assembly 100 around the first axis L1. The roller brush assembly 200 can rotate around the first axis L1 to clean the surface to be cleaned 2 during the rotation. Exemplarily, the roller brush assembly 200 is a long strip structure, and both ends of the roller brush assembly 200 are rotatably connected to the support assembly 100 around the first axis L1. The outer side of the roller brush assembly 200 is wrapped with a dust absorbing structure such as flannel hair, and the dust absorbing structure rubs against the surface to be cleaned 2 to clean the surface to be cleaned 2. Exemplarily, the surface to be cleaned 2 is a surface to be cleaned such as the ground and the desktop.

[0038] For example, Fig.13 As shown, the cleaning robot 1 has a running wheel 30. The first axis L1 is parallel to the rotation axis of the running wheel 30. The rotation direction of the roller brush assembly 200 is opposite to the rotation direction of the running wheel 30, so that the roller brush assembly 200 can clean the surface 2 to be cleaned. For example, the running wheel 30 rotates counterclockwise, that is, the cleaning robot 1 moves in the third direction Z1, and the roller brush assembly 200 rotates clockwise. For another example, the running wheel 30 rotates clockwise, that is, the cleaning robot 1 moves in the fourth direction Z2, and the roller brush assembly 200 rotates counterclockwise. The fourth direction Z2 is opposite to the third direction Z1.

[0039] The cleaning assembly 300 is rotatably connected to the supporting assembly 100 around the second axis L2. The outer side of the cleaning assembly 300 contacts the outer side of the roller brush assembly 200. The cleaning assembly 300 can rotate around the second axis L2 to clean the roller brush assembly 200 during the rotation. Exemplarily, the outer side of the cleaning assembly 300 has a cleaning structure such as a flexible brush and comb teeth, and the cleaning structure contacts the outer side of the roller brush assembly 200 and generates friction with the outer side of the roller brush assembly 200 to clean up the debris adsorbed on the outer side of the roller brush assembly 200.

[0040] The dust box assembly 400 is disposed below the cleaning assembly 300, connected to the support assembly 100, and configured to receive the debris cleaned by the cleaning assembly 300 from the roller brush assembly 200. The dust box assembly 400 has an air suction channel 410, which can be communicated with the dust box assembly 21 of the cleaning robot 1, so that the dust box assembly 21 can suck away the debris in the dust box assembly 400.

[0041] Exemplarily, the dust box assembly 400 is detachably connected to the support assembly 100 to facilitate maintenance of the dust box assembly 400. Exemplarily, the dust box assembly 400 has a storage space 420 and an air suction channel 410 connecting the storage space and the dust box assembly 21. The storage space 420 can receive the debris cleaned from the roller brush assembly 200 by the cleaning assembly 300, and the dust box assembly 21 can suck away the debris in the storage space 420 through the air suction channel 410. Exemplarily, as Figure 1 As shown, the dust box assembly 400 includes a third hand screw 430 and a fifth threaded hole, and the support assembly 100 has a sixth threaded hole. The third hand screw 430 is screwed to the fifth threaded hole and the sixth threaded hole respectively to achieve a detachable connection between the dust box assembly 400 and the support assembly 100.

[0042] By setting up the cleaning component 300, the cleaning component 300 can be used to clean the debris on the roller brush component 200 to the dust box component 400, thereby realizing automatic cleaning of the roller brush component 200, reducing the frequency of manual cleaning of the roller brush component 200, thereby reducing the frequency of manual cleaning of the dust pusher component 10, and realizing the long endurance effect of the cleaning robot 1.

[0043] In addition, the dust box assembly 400 has an air suction channel 410, which can be connected to the dust box assembly 21 of the cleaning robot 1, so that the dust box assembly 21 can suck away the debris in the dust box assembly 400, reduce the frequency of cleaning the dust box assembly 400, and further reduce the frequency of manual cleaning of the dust pushing assembly 10. Exemplarily, the dust box assembly 21 includes an air suction structure, which is used to provide negative pressure to the dust box assembly 400 to suck away the debris in the dust box assembly 400.

[0044] In some embodiments, the dust pusher assembly 10 further includes a transmission assembly 500. The transmission assembly 500 is connected to the roller brush assembly 200 and the cleaning assembly 300 so that the cleaning assembly 300 and the roller brush assembly 200 rotate in the same direction.

[0045] For example, Figure 3 As shown, the cleaning assembly 300 may be located on one side of the roller brush assembly 200. For example, the cleaning assembly 300 may be located above or below the roller brush assembly 200. Figure 3 As shown, there is a debris passage space above and on the left side of the cleaning assembly 300. When the cleaning assembly 300 rotates counterclockwise, debris can pass through the debris passage space above and on the left side of the cleaning assembly 300 and then fall into the dust box assembly 400.

[0046] Exemplarily, the transmission assembly 500 is a belt drive, a gear drive, a chain drive, etc. For example, Figure 4 The structure of the belt drive is shown. Figure 4As shown, the transmission assembly 500 includes a first pulley 510, a second pulley 520 and a transmission belt 530. The first pulley 510 is connected to the roller brush assembly 200, the second pulley is connected to the cleaning assembly 300, and the transmission belt 530 is sleeved on the first pulley 510 and the second pulley 520 to transmit the power of the first pulley 510 to the second pulley 520. The first pulley 510 and the second pulley 520 rotate in the same direction, so that the cleaning assembly 300 and the roller brush assembly 200 rotate in the same direction, which is convenient for increasing the friction between the cleaning assembly 300 and the roller brush assembly 200, and improving the cleaning effect of the cleaning assembly 300 on the roller brush assembly 200.

[0047] In some embodiments, Figure 6 As shown, the air suction channel 410 includes a plurality of sub-air suction channels 411. The plurality of sub-air suction channels 411 are sequentially arranged along a first direction X. The first direction X is parallel to the extension direction of the first axis L1.

[0048] By providing a plurality of sub-suction channels 411, the adsorption force can pass through the plurality of sub-suction channels 411 evenly, thereby improving the uniformity of suctioning away debris, and allowing debris in the edge area of ​​the dust box assembly 400 to be suctioned away, thereby improving the adsorption effect on the debris.

[0049] In some embodiments, Figure 3 and Figure 6 As shown, the air suction channel 410 includes a first channel section 412 , at least one partition 413 and a second channel section 414 .

[0050] The dimension of the first channel section 412 in the first direction X gradually decreases along the second direction Y, so that the first channel section 412 forms a trumpet-shaped structure, thereby improving the adsorption effect of the first channel section 412. The second direction Y is perpendicular to the first direction X, and the second direction Y is the direction from the dust box assembly 400 to the dust box assembly 21.

[0051] At least one partition 413 is sequentially arranged in the first channel section 412 along the first direction X to divide the first channel section 412 into a plurality of sub-suction channels 411. Figure 6 As shown, the partition 413 is a curved plate-like structure.

[0052] The second channel section 414 connects the plurality of sub-suction channels 411 with the dust box assembly 21. Exemplarily, the second channel section 414 is a tubular structure.

[0053] In some embodiments, the maximum dimension of the first channel section 412 in the first direction X is greater than or equal to the dimension of the roller brush assembly 200 from the first end to the second end in the first direction X, that is, the first channel section 412 covers the roller brush assembly 200 in the first direction X, so that debris dropped from the roller brush assembly 200 can be better absorbed through the first channel section 412.

[0054] In some embodiments, Figure 6 As shown, there are two partitions 413, and the two partitions 413 form three sub-suction channels 411. The size of the middle sub-suction channel 411 in the first direction X gradually decreases along the second direction Y, that is, the middle sub-suction channel 411 forms a trumpet-shaped structure, which improves the adsorption effect of the middle sub-suction channel 411.

[0055] In some embodiments, the roller brush assembly 200 includes a cylindrical body 210 and a spiral wool strip 220. The cylindrical body 210 is rotatably connected to the support assembly 100 around a first axis L1. The axis of the cylindrical body 210 coincides with the first axis L1. The spiral wool strip 220 is connected to the outer side of the cylindrical body 210.

[0056] Exemplarily, the material of the spiral wool strip 220 includes flannel wool. Flannel wool has strong adsorption force, and the spiral wool strip 220 made of flannel wool has stronger adsorption force on dust and other debris, further improving the adsorption effect of the roller brush assembly 200.

[0057] Exemplarily, the roller brush assembly 200 further includes a driving source 230. The driving source 230 is disposed in the cylindrical body 210 and connected to the cylindrical body 210 so that the driving source 230 drives the cylindrical body 210 to rotate around the first axis L1. Exemplarily, the driving source 230 is a roller motor. Exemplarily, the driving source 230 can also be a structure that can provide a rotational force, such as a rotary electric cylinder.

[0058] In some embodiments, the cleaning assembly 300 includes a columnar body 310 and a brush 320. The columnar body 310 is rotatably connected to the support assembly 100 around the second axis L2. The axis of the columnar body 310 coincides with the second axis L2. The brush 320 is connected to the columnar body 310. The brush 320 extends radially along the columnar body 310. At least part of the brush 320 can contact the spiral wool strip 220.

[0059] Exemplarily, the brush 320 is made of nylon hair, that is, the nylon hair is implanted on the columnar body 310, which is convenient for automated production and low in cost.

[0060] In some embodiments, Figure 3 , Figure 8 and Fig. 9 As shown, the dust pusher assembly 10 further includes a plurality of comb teeth 600. The plurality of comb teeth 600 are connected to the support assembly 100. The comb teeth 600 extend toward the brush 320, and at least a portion of the comb teeth 600 contacts at least a portion of the brush 320, so that at least a portion of the comb teeth 600 can clean the filaments wound around the brush 320, thereby using the comb teeth 600 to clean the brush 320, thereby reducing the frequency of manual cleaning of the cleaning assembly 300.

[0061] Exemplarily, the filament is hair, fur or the like.

[0062] In some embodiments, the roller brush assembly 200 is detachably connected to the support assembly 100 via a first hand screw 240 , so as to facilitate the disassembly of the roller brush assembly 200 .

[0063] Exemplarily, the dust pusher assembly 10 includes a first connecting shaft, and the first connecting shaft is connected to the hole axis of the support assembly 100. The first connecting shaft has a first threaded hole, and the first end of the roller brush assembly 200 has a second threaded hole. The first hand screw 240 realizes the detachable connection between the roller brush assembly 200 and the first connecting shaft through the first threaded hole and the second threaded hole. Exemplarily, a bearing can also be arranged between the first connecting shaft and the support assembly 100 to improve the flexibility of rotation of the first connecting shaft. Exemplarily, the second end of the roller brush assembly 200 is connected to the hole axis of the support assembly 100. A fisheye bearing can be arranged between the second end of the roller brush assembly 200 and the support assembly 100 to facilitate the disassembly of the roller brush assembly 200.

[0064] In some embodiments, the cleaning assembly 300 is detachably connected to the supporting assembly 100 via a second hand-tightening screw 330 , so as to facilitate the disassembly of the cleaning assembly 300 .

[0065] Exemplarily, the dust push assembly 10 includes a second connecting shaft, and the second connecting shaft is connected to the support assembly 100 hole shaft. The second connecting shaft has a third threaded hole, and the first end of the cleaning assembly 300 has a fourth threaded hole. The second hand screw 330 realizes the detachable connection between the cleaning assembly 300 and the second connecting shaft through the third threaded hole and the fourth threaded hole. Exemplarily, a bearing can also be provided between the second connecting shaft and the support assembly 100 to improve the flexibility of rotation of the second connecting shaft. Exemplarily, the second end of the cleaning assembly 300 is connected to the support assembly 100 hole shaft. A fisheye bearing can be provided between the second end of the cleaning assembly 300 and the support assembly 100 to facilitate the disassembly of the cleaning assembly 300.

[0066] In some embodiments, the dust pusher assembly 10 further includes a maintenance cover 700. Fig.12 As shown, the edge of the maintenance cover 700 has at least one first magnetic attraction member 710. Fig.11 As shown, the support assembly 100 has at least one second magnetic member 110 corresponding to at least one first magnetic member 710, and the maintenance cover 700 and the support assembly 100 are covered by at least one first magnetic member 710 and at least one second magnetic member 110, which facilitates the removal of the maintenance cover 700. After the maintenance cover 700 is removed, the operating space for replacing the roller brush assembly 200 and the cleaning assembly 300 is increased, the field of vision is wide, and it is convenient to better replace the roller brush assembly 200 and the cleaning assembly 300.

[0067] Exemplarily, the support assembly 100 has limiting parts at both ends in the first direction X, and the maintenance cover 700 can be engaged with the limiting parts of the support assembly 100 at both ends in the first direction X to achieve limiting of the maintenance cover 700 in the first direction X.

[0068] For example, Fig.12 As shown, the maintenance cover 700 is an arc-shaped structure, and the limiting portion of the support assembly 100 is an arc-shaped limiting portion that cooperates with the arc-shaped structure of the maintenance cover 700, so as to limit the maintenance cover 700 by utilizing the arc-shaped structure.

[0069] For example, Fig.12 As shown, the outer side surface of the maintenance cover 700 also has a mounting and disassembly groove 720, which is convenient for the user to take the maintenance cover 700 through the mounting and disassembly groove 720, thereby facilitating the mounting and disassembly of the maintenance cover 700.
