[0043] It should also be noted that the term "includes", "comprising" or any other variation thereof is intended to cover non-exclusive inclusion, so that a commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such commodity or device. In the absence of more restrictions, the elements defined by the sentence "comprising a ..." do not exclude the existence of other identical elements in the commodity or device including the elements.

[0044] In the cleaning module of the related art, the cleaning module has a single cantilever roller brush. Since the dust suction port of the single cantilever roller brush is arranged at the cantilever end, the garbage at the supporting end has to travel a long distance to reach the dust suction port. Since the single cantilever roller brush cannot form a closed space with the ground, the garbage must pass through the cooperation of the brush member to be swept into the dust suction port, and the cleaning efficiency is low.

[0045] Based on this, the utility model provides a cleaning module, including: a roller brush bracket; at least a first roller brush, one end of the first roller brush is mounted on the roller brush bracket, and the other end is a free end; at least a second roller brush, one end of the second roller brush is mounted on the roller brush bracket, and the other end is a free end; the first roller brush and the second roller brush are arranged side by side. . The cleaning module provided by the embodiment of the present disclosure includes a double cantilever roller brush arranged side by side. When cleaning the ground, the cleaning module can form a closed space through the double roller brushes and the ground, which is conducive to forming negative pressure, making it easy for garbage to be sucked into the cleaning device, and improving the cleaning efficiency.

[0046] The optional embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0047] The present disclosure provides a cleaning module. Figure 1 As shown, the cleaning module is used to clean the object to be cleaned on the cleaning surface. The cleaning module includes a roller brush bin 100, a cleaning brush head 600 and a gear box 400. The cleaning brush head 600 includes a roller brush cover 200 and a roller brush 300. The roller brush 300 is connected to the roller brush bin 100 on one side and rotates under the driving force provided by the gear box 400. Figure 2 As shown, the roller brush bin 100 has a driving end 110 and a non-driving end 120; wherein the driving end 110 is connected to the gear box 400, and the gear box 400 provides driving force through the driving end 110; between the driving end 110 and the non-driving end 120 of the roller brush bin 100 is a accommodating space 130, and the accommodating space is configured to accommodate two roller brushes 300, and the two roller brushes 300 are arranged side by side.

[0048] In some embodiments, Figure 2As shown, the roller brush bin 100 has a limiting groove 150 on one side close to the driving end 110. The closer the limiting groove 150 is to the driving end 110, the deeper it is, which is convenient for obliquely inserting the roller brush cover 200 and the roller brush 300. The roller brush bin 100 has a groove 170 on the end surface of the side wall, and the groove 170 is used for stably engaging with the roller brush cover 200.

[0049] In some embodiments, see Figure 2 The roller brush bin 100 further includes a locking member 160 , which is disposed on a side close to the non-driving end 120 of the roller brush bin 100 , and is used to lock the roller brush cover 200 .

[0050] In some embodiments, Figure 3 As shown, the roller brush bin 100 also has a dust suction port 140, and the dust suction port 140 is arranged on a side close to the non-driving end 120 of the roller brush bin 100. Optionally, the side wall of the roller brush bin 100 close to the dust suction port 140 has an eccentric structure 141, and the eccentric structure 141 is configured to make it easier for the cleaned object to enter the dust suction port 140. When the cleaned object moves along the brush member of the roller brush 300 from the driving end 110 of the roller brush bin 100 to the non-driving end 120 and falls off from the end of the brush member of the roller brush 300, it is just located at the eccentric structure 141. Since the cleaned object also has a spiral motion along the circumferential direction, it matches the eccentric direction of the eccentric structure 141 and smoothly enters the dust suction port 140, thereby improving the efficiency of dust removal.

[0051] In some embodiments, Figure 3 As shown, the driving end 110 of the roller brush bin 100 has an air inlet 111, which is configured to allow airflow to flow axially along the roller brush 300 to drive the object to be cleaned to move axially along the roller brush, and finally be sucked away through the suction port 140. The air inlet 111 enhances the efficiency of the object to be cleaned leaving the roller brush.

[0052] In some embodiments, Figure 4As shown, the cleaning brush head 600 includes a roller brush cover 200 and a roller brush 300, and the cleaning brush head 600 is detachably connected to the roller brush bin 100, and one side of the roller brush cover 200 has a roller brush support frame 210, and the roller brush support frame 210 is configured to be connected to one end of the roller brush 300 so that the roller brush 300 is set on the roller brush cover 200, so that the roller brush 300 and the roller brush cover 200 form an integral structure that can be freely assembled or freely disassembled from the roller brush bin 100; in response to one end of the roller brush cover 200 with the roller brush support frame 210 being inserted into the driving end 110 of the roller brush bin 100, the roller brush cover 200 equipped with the roller brush 300 is set in the roller brush bin 100. It can be understood from the above structure that the roller brush 300 provided by the utility model is arranged on the roller brush cover 200 through the roller brush support frame 210 to form an integrally detachable cleaning brush head 600. Since the roller brush 300 and the roller brush cover 200 are a firmly connected structure, and the roller brush cover 200 and the roller brush bin 100 are also firmly connected structures, the roller brush 300 is not easy to fall off from the roller brush bin 100 during the rotation and use process. In addition, when the roller brush needs to be replaced, the roller brush can be directly removed together with the cleaning brush head by disassembling it, without having to disassemble the roller brush cover first and then disassembling the roller brush, which saves the disassembly procedures and facilitates the replacement of the roller brush.

[0053] In some embodiments, reference Figure 5-Figure 7 In the cleaning brush head 600, the roller brush cover 200 has a roller brush support frame 210 on one side close to the driving end 110 of the roller brush bin 100. The number of roller brush support frames 210 corresponds to the number of roller brushes 300 and is used to support the roller brushes 300. The roller brush support frame 210 includes an axially extending connecting rod 211. One end of the roller brush 300 has an axially extending recessed portion 310. The connecting rod 211 is inserted into the recessed portion 310 so that the roller brush 300 is arranged on the roller brush cover 200. Figure 6 shown.

[0054] In some embodiments, Figure 5 As shown, the cleaning brush head 600 also includes a driving structure 500, and the driving structure 500 is connected to the hollow connecting rod 211 and the roller brush 300 along the axial direction of the roller brush, so that the driving structure 500, the roller brush cover 200 and the roller brush 300 form a stable connection structure, and the driving structure 500 drives the roller brush 300 to rotate under the drive of the driving box 400.

[0055] In some embodiments, Figure 6As shown, the driving structure 500 includes a driving shaft 510 extending in the axial direction, and the driving shaft 510 passes through the connecting rod 211 in the axial direction and is connected to the roller brush 300. In some embodiments, the driving shaft 510 has a bonding structure 511 at one end away from the roller brush, and the bonding structure 511 is configured to be connected to the driving end 110 of the roller brush bin 100, and the bonding structure 511 is set to a polygonal or plum-shaped structure. Correspondingly, as Figure 7 As shown, the output shaft end of the gearbox 400 has a snap-in recess 410, which is also a polygonal or plum-shaped structure. The snap-in recess 410 matches the outer contour of the bonding structure 511, so that the bonding structure 511 can be stably connected to the snap-in recess 410 and rotate under the drive of the output shaft of the gearbox 400. In some embodiments, as Figure 6-7 As shown, the outer edge of the snap-in recess 410 has an inclined surface 411 away from the center, and the size of the outer contour of the inclined surface 411 is larger than the size of the internal aperture of the snap-in recess 410. This arrangement facilitates the installation of the bonding structure 511. When the overall structure of the roller brush cover 200 and the roller brush 300 is assembled in the roller brush bin 100, the overall structure of the roller brush cover 200 and the roller brush 300 needs to be first inserted into the roller brush bin 100 at an angle, and then inserted into the snap-in recess 410 horizontally along the axial direction. During the inclined insertion process, the bonding structure 511 first contacts the inclined surface 411. The larger outer contour size of the inclined surface 411 provides the bonding structure 511 with a larger redundant space, so that the overall structure of the roller brush cover 200 and the roller brush 300 can be smoothly inserted into the snap-in recess 410, thereby connecting with the output shaft of the gear box 400. One end of the driving shaft 510 inserted into the roller brush 300 has a spiral structure 512, and the spiral structure 512 is configured to be tightly connected to the spiral groove of the roller brush 300. The setting of the spiral structure 512 can make it difficult for the roller brush 300 to fall off the roller brush cover 200 in the axial direction. In addition, it can also make the roller brush able to rotate stably under the drive of the driving structure 500.

[0056] In some embodiments, Figure 8 As shown, the cleaning module includes a first roller brush 301, one end of the first roller brush 301 is mounted on the roller brush bracket, and the other end is a free end; a second roller brush 302, one end of the second roller brush 302 is mounted on the roller brush bracket, and the other end is a free end; the first roller brush 301 and the second roller brush 302 are arranged side by side, and the cleaning module may also include multiple first roller brushes 301 and multiple second roller brushes 302 to form multiple side-by-side structures. This embodiment is described by taking two roller brushes arranged side by side as an example.

[0057] like Figure 8As shown, when the cleaning module is cleaning the floor, the first roller brush 301 and the second roller brush 302 rotate counterclockwise and clockwise respectively, forming a first triangular area 350 between the first roller brush 301 and the second roller brush 302 and the cleaning floor, in which a negative pressure is formed by the suction of the fan, so that the garbage is sucked into the suction port 140. At the same time, a second triangular area 360 is formed between the first roller brush 301 and the second roller brush 302 and the inner wall of the cleaning chamber 100, in which a negative pressure is also formed by the suction of the fan, so that the garbage is sucked into the suction port 140. Therefore, the design of the double roller brush can enhance the adsorption strength of the cleaned object through the two triangular areas and improve the cleaning efficiency. The suction port of the cantilever main brush must be set at the cantilever end, so that the garbage at the support end has to travel a long distance to reach the suction port, and the single cantilever main brush needs to cooperate with the brush member to sweep the garbage into the suction port. Therefore, the single roller brush lacks the "triangular area channel" of the double roller brushes, and often requires the main brush to rotate in the roller brush compartment multiple times before reaching the dust suction port, affecting the cleaning efficiency.

[0058] In some embodiments, Fig. 9 , Fig.10 As shown, the roller brush 300 includes a brush member 340 spirally extending from the assembly end 320 to the free end 330. In response to the rotation of the roller brush 300, the object to be cleaned moves along the brush member 340 from the assembly end 320 to the free end 330. Optionally, the roller brush 300 includes a cylindrical member and a shaft, the cylindrical member is sleeved outside the shaft and rotates with the rotation of the shaft, and the length of the cylindrical member is not less than the length of the shaft to prevent hair and the like from entering the shaft. Optionally, the brush member 340 extends from the cylindrical member in a direction away from the shaft, and the thickness of the distal end of the brush member 340 is different from the thickness of the root of the brush member 340, for example, the thickness of the distal end of the brush member 340 is greater than the thickness of the root of the brush member 340, so as to enhance the cleaning force of the brush member and improve the cleaning efficiency. Optionally, the brush member includes rubber and / or rubber hair, and the rubber hair can enhance the cleaning effect of the hair. Optionally, there are multiple brush members 340, and at least one of the multiple brush members 340 has a chamfer 341 or a rounded corner 342 at the free end 330 of the roller brush 300. The chamfer 341 is a slope extending from the free end 330 toward the assembly end 320 at the end of the roller brush 340. The design of the chamfer 341 makes it easier for hair and the like to fall off the brush member 340. The rounded corner 342 is a circular arc structure at the end of the roller brush 340. The design of the rounded corner 342 also makes it easier for hair and the like to fall off the brush member 340. Optionally, at the free end of the roller brush, the arc of the rounded corner 342 of one of the brush members 340 is greater than a preset value. The preset value makes the end of the brush member 340 extend in a direction close to perpendicular to the axial direction of the roller brush, thereby increasing the cleaning width and having little effect on the shedding of hair on the roller brush.

[0059] In some embodiments, Fig.11 As shown, the line connecting the end of the brush 340 to the root and the line connecting the root to the axis of the roller brush have a preset angle A, which is greater than 0 degrees and less than 90 degrees. Thus, the brush 340 can be made longer, the brush 340 as a whole becomes softer, the contact force with the ground is smaller, and the cleaning noise is smaller.

[0060] In some embodiments, a circumferentially extending wool ring is provided at the assembly end 320 of the roller brush 300. The wool ring rotates with the roller brush 300 and is configured to block hair and prevent the hair from entering the bearing and thus damaging the bearing.

[0061] In some embodiments, a blocking groove is provided at the assembly end 320 of the roller brush 300 to temporarily store some hair to prevent the hair from entering the bearing and damaging the bearing.

[0062] In some embodiments, Fig.12 As shown, the roller brush cover 200 includes a shell 240 and a roller brush support frame 210, the roller brush support frame 210 is arranged at one end of the shell 240, and the roller brush support frame 210 is configured to cooperate with the assembly end 320 of the roller brush 300. The roller brush cover 200 and the roller brush 300 form a structure that can be independently disassembled and installed from the cleaning device, so as to facilitate the user to replace the roller brush. Optionally, the shell 240 includes an avoidance portion 260, which is arranged at one end of the shell 240 away from the roller brush support frame 210, and the avoidance portion 260 is configured to avoid the free end 330 of the roller brush 300.

[0063] In some embodiments, Fig.12 As shown, the roller brush support frame 210 includes an end cap 212, which is substantially perpendicular to the axial direction of the roller brush 300 and configured to abut against the end of the roller brush 300; the end cap 212 has an edge portion extending along the axial direction of the roller brush 300, which is used to better support the roller brush 300. The roller brush support frame 210 also includes a connecting rod 211, which is substantially perpendicular to the end cap 212 and extends along the axial direction, and is configured to be connected to the assembly end 320 of the roller brush 300. The connecting rod 211 is a hollow structure, which is convenient for the driving structure 500 to pass through and drive the roller brush to rotate.

[0064] In some embodiments, Fig.12 As shown, the end cap 212 includes a step portion 2121, which is arranged around the root of the connecting rod 211 and is configured to abut against the end of the roller brush 300. The step portion 2121 generally forms a structure with different heights along the axial direction to adapt to the end of the roller brush 300 for stable connection.

[0065] In some embodiments, Fig.13 As shown, the roller brush support frame 210 further includes a clamping member 2122, which is disposed at the edge of the end cover 212, and is configured to elastically clamp the end of the roller brush 300. There is a gap between the clamping member 2122 and the edge of the end cover 212, so that it has a certain elasticity in the radial direction. When the roller brush 300 is assembled on the end cover 212, the clamping member 2122 is squeezed and expands radially outward. After the roller brush 300 is assembled on the end cover 212, the clamping member 2122 rebounds and clamps the end of the roller brush 300. Optionally, the clamping member 2122 has a clamping protrusion 2123 on one side facing the roller brush 300, and the clamping protrusion 2123 is configured to further clamp the end of the roller brush 300.

[0066] In some embodiments, Fig.13 As shown, the roller brush cover 200 further includes a limiting protrusion 220, which is disposed on one side of the housing 240 close to the roller brush assembly end 320. The limiting protrusion 220 is configured to be locked with the roller brush bin 100 in a limiting manner.

[0067] In some embodiments, Fig.13 As shown, the roller brush cover 200 further includes a limiting rib 250, which is axially extending and arranged on at least one side wall end face of the housing 240. When the roller brush cover 200 is assembled with the roller brush bin 100, the limiting rib 250 is engaged with the groove on the roller brush bin 100.

[0068] In some embodiments, Fig.14 As shown, the roller brush support frame 210 further includes at least one support portion 2124, which protrudes from the outer surface of the end cover 212 and extends in a direction away from the roller brush 300. The support portion 2124 is configured to assist in supporting the roller brush cover 200 when the roller brush cover 200 is assembled in the roller brush bin 100.
