[0061] To make the objectives, technical solutions, and advantages of the present disclosure more clear, the present disclosure will be further described in detail below with reference to the accompanying drawings. It is apparent that the embodiments described are only a portion of the embodiments of the present disclosure, rather than all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present disclosure without creative effort are intended to fall within the scope of protection of the present disclosure.

[0062] The terms used in the embodiments of the present disclosure are for the purpose of describing specific embodiments only and are not intended to limit the present disclosure. The singular forms "a," "the," and "the" used in the embodiments of the present disclosure and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. "A variety of" generally includes at least two, and other quantifiers are similar.

[0063] It should be understood that although the terms "first," "second," "third," etc. may be used to describe in the present disclosure, these descriptions should not be limited to these terms. These terms are only used to distinguish the objects being described. For example, without departing from the scope of the present disclosure, the first may also be referred to as the second, and similarly, the second may also be referred to as the first. In addition, the terms "first," "second," "third," etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0064] It should be understood that the term "and / or" as used herein is merely a description of an association between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, and B exists alone. Furthermore, the character " / " as used herein generally indicates that the associated objects are in an "or" relationship. The singular forms "a," "the," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0065] In the description of this disclosure, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; and direct connections or indirect connections through an intermediary.

[0066] It should also be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or device comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or device. In the absence of further limitations, an element defined by the phrase "comprises a..." does not exclude the presence of other identical elements in the product or device comprising the element.

[0067] In the related art, the roller brush moves the object to be cleaned to one end of the roller brush chamber during rotation, and then is sucked away by the dust suction port set at the end of the roller brush chamber for cleaning. This cleaning brush head increases the distance of the object to be cleaned and reduces cleaning efficiency. As user demand continues to increase, a cleaning brush head that can clean more conveniently and efficiently is urgently needed.

[0068] Therefore, the present disclosure provides a cleaning brush head, comprising: a roller brush magazine having an accommodating space; a roller brush assembly, comprising at least a first roller brush, a second roller brush, a third roller brush and a fourth roller brush, wherein the first roller brush, the second roller brush, the third roller brush and the fourth roller brush each include an assembly end and a free end, wherein the assembly end is driven by a driving device, and the free end of the first roller brush is arranged opposite to the free end of the second roller brush, and a first gap is formed; the free end of the third roller brush is arranged opposite to the free end of the fourth roller brush, and a second gap is formed; the first gap and the second gap at least partially overlap in the radial direction.

[0069] The cleaning brush head provided by the present disclosure includes a roller brush assembly, which includes at least a first roller brush, a second roller brush, a third roller brush and a fourth roller brush. The first roller brush, the second roller brush, the third roller brush and the fourth roller brush all include an assembly end and a free end. The free end of the first roller brush is arranged opposite to the free end of the second roller brush, and a first gap is formed; the free end of the third roller brush is arranged opposite to the free end of the fourth roller brush, and a second gap is formed. The first gap and the second gap at least partially overlap in the radial direction, so as to facilitate the cleaned object to move from the end of the roller brush to the middle and be sucked away, thereby improving the cleaning efficiency.

[0070] Optional embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0071] like Figure 1As shown, the first aspect of the present disclosure provides a cleaning brush head 1000 comprising: a roller brush bin 200, a roller brush support frame 300, a gear box 400, and a roller brush assembly 100. The cleaning brush head 1000 can be assembled in a cleaning device to clean objects to be cleaned on an operating surface. The cleaning brush head 1000 comprises a roller brush bin 200, and the roller brush bin 200 has a driving end 210, wherein the driving end 210 is provided with at least one. The driving end 210 is connected to the gear box 400, and the gear box 400 provides driving force through the driving element. The roller brush magazine 200 has a accommodating space 201, and the accommodating space 201 is configured to accommodate the roller brush assembly 100. The roller brush assembly 100 includes at least a first roller brush, a second roller brush, a third roller brush and a fourth roller brush. The first roller brush, the second roller brush, the third roller brush and the fourth roller brush all include an assembly end 101 and a free end 102. The assembly end 101 is connected to the end of the roller brush magazine 200, and the free end 102 extends roughly to the middle of the accommodating space 201; wherein, the assembly end 101 is driven by a driving device, the free end of the first roller brush is arranged opposite to the free end of the second roller brush, and a first gap is formed; the free end of the third roller brush is arranged opposite to the free end of the fourth roller brush, and a second gap is formed; the first gap and the second gap at least partially overlap in the radial direction, so that the cleaned object is moved from the end of the roller brush to the middle and then sucked away, thereby improving the cleaning efficiency. Optionally, the widths of the first gap and the second gap may be equal or unequal. Therefore, at least partial overlap of the first gap and the second gap in the radial direction generally includes at least one of the following situations: complete overlap when the first gap and the second gap are equal, partial overlap after misalignment; inclusive overlap when the first gap and the second gap are unequal, partial overlap after misalignment. The first gap and the second gap are configured to at least partially overlap in the radial direction so that the first gap and the second gap are connected in a direction perpendicular to the radial direction, thereby allowing the object to be cleaned to move freely in a direction perpendicular to the axial direction. When the object to be cleaned moves to the free end along the axial direction of any roller brush, it is freely sucked away after passing through the first gap and the second gap, thereby improving cleaning efficiency.

[0072] In some embodiments, the first and second roller brushes are coaxial, and the third and fourth roller brushes are coaxial. Arranging the two roller brushes approximately on the same axis can reduce the perpendicular axial dimension of the cleaning brush head, thereby reducing the overall size of the cleaning brush head. The coaxial arrangement of the two roller brushes allows objects to be cleaned on both sides to simultaneously move toward the free ends of the roller brushes, where they are collected in the receiving space 201 and then sucked away, thereby improving cleaning efficiency.

[0073] like Figure 2As shown, the first roller brush, the second roller brush, the third roller brush, and the fourth roller brush can be tilted and rotated in a direction perpendicular to the axial direction as the roller brush support frame 300 rotates. When the first roller brush, the second roller brush, the third roller brush, and the fourth roller brush are rotated to the axially tilted position, the first roller brush, the second roller brush, the third roller brush, or the fourth roller brush can be freely removed from the roller brush support frame 300, or a new roller brush can be replaced and inserted into the roller brush support frame 300. Then, the first roller brush, the second roller brush, the third roller brush, or the fourth roller brush is rotated to the axial position, and the first roller brush, the second roller brush, the third roller brush, or the fourth roller brush is assembled in the accommodating space 201. It can be seen that the first roller brush, the second roller brush, the third roller brush, or the fourth roller brush of the cleaning brush head disclosed in the present invention can be independently disassembled and assembled, and replacement is convenient.

[0074] This disclosure takes the assembly method of one roller brush as an example to illustrate, and the assembly method of multiple roller brushes is understood by referring to the assembly method of one roller brush.

[0075] In some embodiments, as Figure 3 As shown, the roller brush includes a roller brush body 110, and the surface of the roller brush body 110 is provided with bristles and / or brush members 111, and the brush member 111 is, for example, a spiral brush member. The spiral brush member 111 is tilted on the roller brush body 110, and is configured to transport the dirt and dust on the operating surface to the dust collection channel 1100. The spiral brush member 111 can be inserted axially into a slot on the outer surface of the roller brush body 110, or can be integrally formed with the roller brush body 110, and there is no limitation on this. On the roller brush body 110, multiple groups of the spiral brush members 111 can be provided. The bristles can be arranged between at least two groups of the spiral brush members 111, and can be arranged roughly parallel to the spiral brush members 111, and can be configured to assist in cleaning the operating surface.

[0076] Furthermore, the spiral brush member 111 has a fixed end connected to the roller brush body 110 and a free end away from the roller brush body 110. The free end of the spiral brush member 111 can be tilted toward the middle of the roller brush body 110. Under this structural design, hair or dirt entangled on the roller brush body 110 will rotate with the roller brush. Under the action of the tilted spiral brush member 111, the entangled material is transported from the fixed end of the roller brush body 110 toward the free end of the roller brush body 110, so that the entangled material is transported to the dust collection channel 1100. The free end 102 of the roller brush can be provided with an end cap 140. The end cap 140 is configured to prevent dust from entering the roller brush, causing contamination of the drive shaft 320, and oxidation of the inner wall of the roller brush, which is difficult to separate from the drive shaft 320. The end cap 140 is also used during the assembly process of the spiral brush 111. When the end cap 140 is not installed, the spiral brush 111 can be axially inserted into a slot on the outer surface of the roller brush body 110 from the free end of the roller brush body 110. After the spiral brush 111 is assembled, the end cap 140 is snapped onto the free end 102 of the roller brush body 110 to prevent the spiral brush 111 from falling off. In some embodiments, the first roller brush, the second roller brush, the third roller brush, or the fourth roller brush further includes a rubber brush member and / or a bristle brush member. In response to the rotation of the first roller brush, the second roller brush, the third roller brush, or the fourth roller brush, the object to be cleaned moves along the rubber brush member and / or the bristle brush member from the assembly end to the free end. The first roller brush includes a first brush component, the second roller brush includes a second brush component, the third roller brush includes a third brush component, and the fourth roller brush includes a fourth brush component. The structures of at least two of the first brush component, the second brush component, the third brush component, and the fourth brush component are the same or different.

[0077] In some embodiments, to prevent entangled objects on the surface of the roller brush body 110 from entering the interior of the drive end 210, the roller brush further includes a roller brush baffle 150. The roller brush baffle 150 is disposed at one end of the roller brush body 110 and extends in a radially annular manner toward the roller brush body 110. In the radial direction of the roller brush body 110, the diameter of the roller brush baffle 150 is greater than the diameter of the roller brush body 110, and is configured to isolate the roller brush body 110 from the drive end 210, thereby preventing entangled objects on the roller brush body 110 from entering the interior of the drive end 210.

[0078] Specifically, when the roller brush is in normal working condition and rotates at high speed, the dirt and dust wrapped around the surface of the roller brush body 110 will be transported from the assembly end 101 of the roller brush body 110 toward the free end 102. The setting of the roller brush baffle 150 can effectively prevent the dirt and dust from entering the interior of the driving end 210.

[0079] In some embodiments, as Figure 1-Figure 3As shown, the roller brush support frame 300 is assembled to the drive end 210 of the roller brush chamber 200 and is configured to rotate within a preset angle about the connection position with the drive end 210. One end of each of the first, second, third, and fourth roller brushes includes a plug-in structure 120. Specifically, the plug-in structure 120 is disposed within the interior of each of the first, second, third, and fourth roller brushes and is in communication with at least one end surface of each of the first, second, third, and fourth roller brushes. The plug-in structure 120 is configured to allow the first, second, third, and fourth roller brushes to be freely plugged in and out of the roller brush support frame 300. When the first, second, third, and fourth roller brushes are connected to the roller brush support frame 300 via the plug-in structure 120, the first, second, third, and fourth roller brushes can rotate with the rotation of the roller brush support frame 300. In response to the roller brush support frame 300 rotating to the axial inclined position, the first roller brush, the second roller brush, the third roller brush and the fourth roller brush can be assembled or disassembled from the roller brush support frame 300. In response to the roller brush support frame 300 rotating to the axial position, the first roller brush, the second roller brush, the third roller brush and the fourth roller brush are assembled in the accommodating space 201.

[0080] In some embodiments, the roller brush body 110 is hollow, and the plug-in structure 120 is disposed inside the roller brush and communicates with at least one end surface of the roller brush, configured to allow the roller brush to be freely plugged in and out of the roller brush support frame 300. The plug-in structure 120 has a step portion. In the axial direction of the roller brush, the distance from the step portion to the plane where the roller brush baffle 150 is located is the depth of the plug-in structure 120; in the radial direction of the roller brush, the thickness from the step portion to the inner sidewall of the plug-in structure 120 is the height of the step portion. In actual applications, the depth or height of the step portion can be adjusted to allow the plug-in structure 120 to have different inner diameters. Plug-in structures 120 with different inner diameters are used to accommodate different models of support frame bodies 310.

[0081] In some embodiments, Figure 4 This is a schematic structural diagram of a roller brush support frame in an embodiment of the present disclosure; Figure 5 This is a schematic diagram of the structure of the support frame body in an embodiment of the present disclosure; Figure 6 Schematic diagram of the drive shaft structure in the embodiment of the present disclosure; Figure 4-Figure 6As shown, the roller brush support frame 300 includes: a support frame body 310 and a drive shaft 320. The support frame body 310 is disposed at the driving end 210, and at least one side of the support frame body 310 is in contact with the gear box 400. Specifically, the support frame body 310 is sleeved on the outside of the drive shaft 320 to support the drive shaft 320. One end of the drive shaft 320 is inserted into the support frame body 310 and is detachably connected to the roller brush assembly 100, configured to drive the roller brush assembly 100 to rotate. In response to the roller brush assembly 100 being mounted on the drive shaft 320, the roller brush assembly 100 wraps at least a portion of the support frame body 310.

[0082] In some embodiments, as Figure 6 As shown, the drive shaft 320 includes a fastening structure 321, which is connected to the roller brush assembly 100 to provide driving force for the roller brush assembly 100. When the drive shaft 320 is installed inside the first, second, third, or fourth roller brush, the fastening structure 321 forms an interference fit with the first, second, third, or fourth roller brush, ensuring a tight connection between the first, second, third, or fourth roller brush and the drive shaft 320 and preventing separation. Specifically, the surface of the fastening structure 321 is at least partially recessed, matching the protrusion on the inner wall of the roller brush body 110. The two cooperate to further tighten the connection between the roller brush body 110 and the drive shaft 320.

[0083] In some embodiments, the specific structures of the recesses included in the fastening structures 321 of each drive shaft 320 may be different. For example, the widths or shapes of the recesses in the circumferential direction of the drive shaft 320 may be inconsistent, thereby ensuring that each roller brush must be assembled to the corresponding drive shaft 320, preventing the roller brush from being assembled incorrectly and causing it to be loose or fall off easily during cleaning.

[0084] In some embodiments, the end of the fastening structure 321 has at least one claw 322. When the claw 322 is squeezed under the action of an external force, it can tilt the claw 322 in the direction of the pressure. The claw 322 is configured to be fastened to the locking structure 130 within the first roller brush, the second roller brush, the third roller brush, or the fourth roller brush. Specifically, the locking structure 130 is disposed within the roller brush body 110, on a side of the plug-in structure 120 away from the roller brush baffle 150, and is configured to engage with the fastening structure 321 of the drive shaft 320 to limit the position of the drive shaft 320 within the first roller brush, the second roller brush, the third roller brush, or the fourth roller brush.

[0085] When the drive shaft 320 is installed inside the first, second, third, or fourth roller brush, the drive shaft 320 moves axially inside the roller brush body 110 under the action of thrust. As the drive shaft 320 moves under the action of thrust, the inner wall of the roller brush body 110 applies a certain pressure to the claw 322, causing the claw 322 to deform during movement. In response to the fastening structure 321 moving to the locking structure 130, the claw 322 engages with the locking structure 130. The provision of the fastening structure 321 can prevent the first, second, third, or fourth roller brush from easily falling off the drive shaft 320 in the axial direction. In addition, it can also enable the first, second, third, or fourth roller brush to rotate stably under the drive of the gear box 400. Under the joint action of the plug-in structure 120 and the locking structure 130, the first roller brush, the second roller brush, the third roller brush or the fourth roller brush is engaged with the drive shaft 320, so that the first roller brush, the second roller brush, the third roller brush or the fourth roller brush can be freely plugged in and out of the roller brush support frame 300, and rotates with the rotation of the roller brush support frame 300.

[0086] In some embodiments, as Figure 6 As shown, the drive shaft 320 has a connecting end 324, which is connected to the gear box 400 of the drive end 210 and is configured to drive the roller brush assembly 100 to rotate at high speed to clean the work surface under the drive of the gear box 400. The connecting end 324 of the drive shaft 320 is movably connected to the drive end 210. In response to the pull of the drive shaft 320 under the action of an external force, the drive shaft 320 can tilt relative to the gear box 400 in the axial direction of the drive shaft 320. When the support frame body 310 is mounted on the drive shaft 320, the drive shaft 320 penetrates the support frame body 310 and connects to the roller brush assembly 100. At this time, the roller brush assembly 100 can be pulled to drive the drive shaft 320 and the support frame body 310 to tilt simultaneously in the axial direction of the drive shaft 320. Under this rotation condition, the assembly and disassembly of the roller brush assembly 100 can be made more convenient, and in actual application, the first roller brush, the second roller brush, the third roller brush or the fourth roller brush can be quickly replaced.

[0087] In some embodiments, the connecting end 324 has a bonding structure 323, and the bonding structure 323 is configured to be connected to the driving end 210 of the roller brush bin 200, and the bonding structure 323 is set to a polygonal or plum-shaped structure, such as Figure 5As shown, the drive end 210 of the roller brush cartridge 200 is connected to the gear box 400. The gear box 400 has a snap-in recess 410. This snap-in recess 410 snaps into the bonding structure 323 to drive the first, second, third, or fourth roller brush to rotate. The snap-in recess 410 also has a polygonal or plum-shaped structure, matching the outer contour of the bonding structure 323. This allows the bonding structure 323 to be stably connected to the snap-in recess 410 and rotate under the drive of the output shaft of the gear box 400.

[0088] In some embodiments, as Figure 7 、 Figure 8 As shown, the outer edge of the engaging recess 410 has an inclined surface 411 away from the center. The outer contour of the inclined surface 411 is larger than the inner diameter of the engaging recess 410. This arrangement facilitates the installation of the bonding structure 323. When the drive shaft 320 is installed in the gearbox 400, it is necessary to first insert the drive shaft 320 into the engaging recess 410 at an angle so that the bonding structure 323 is connected to the engaging recess 410, and then push the drive shaft 320 horizontally toward the inside of the engaging recess 410 along the axial direction. During the inclined insertion process, the bonding structure 323 first contacts the inclined surface 411. The larger outer contour of the inclined surface 411 provides the bonding structure 323 with more redundant space, allowing the bonding structure 323 of the drive shaft 320 to be smoothly inserted into the engaging recess 410, thereby connecting to the gearbox 400. At this time, the drive shaft 320 is in an axially inclined position.

[0089] In some embodiments, the drive shaft 320 has an axially tilted position and an axial position after being connected to the gearbox 400. In response to the drive shaft 320 being tilted and inserted into the engaging recess 410, the key structure 323 is connected to the engaging recess 410, and the drive shaft 320 is in the axially tilted position. At this point, the first, second, third, or fourth roller brush can be assembled or removed from the roller brush support frame 300. In response to the drive shaft 320 being tilted and inserted into the engaging recess 410, the key structure 323 is connected to the engaging recess 410, and then the drive shaft 320 is pushed horizontally axially toward the interior of the engaging recess 410, so that the drive shaft 320 is axially connected to the engaging recess 410. At this point, the drive shaft 320 rotates to the axial position, and the first, second, third, or fourth roller brush is assembled in the accommodating space 201, making it impossible to assemble or remove the first, second, third, or fourth roller brush.

[0090] Because the first, second, third, or fourth roller brush is mounted on the drive shaft 320, the first, second, third, or fourth roller brush can rotate synchronously with the drive shaft 320. When the drive shaft 320 is in an axially tilted position, the first, second, third, or fourth roller brush is also in an axially tilted position, but the first, second, third, or fourth roller brush cannot function properly. When the drive shaft 320 is in an axial position, the first, second, third, or fourth roller brush is also in an axial position, and the first, second, third, or fourth roller brush can function properly. In actual application, when the first, second, third, or fourth roller brush is in an axially tilted position, it is easier to assemble or detach the first, second, third, or fourth roller brush from the drive shaft 320. The drive shaft 320 drives the first roller brush, the second roller brush, the third roller brush or the fourth roller brush to extend out from the inside of the roller brush bin 200, thereby preventing the user from getting a lot of dust on their hands when installing or removing the first roller brush, the second roller brush, the third roller brush or the fourth roller brush, thereby improving the user's experience.

[0091] In some embodiments, as Figure 5 、 Figure 9 As shown, the support frame body 310 includes a support end plate 330 and a connecting rod 340, which may be a hollow connecting rod. The hollow connecting rod 340 is configured to fit over the exterior of the drive shaft 320 to assist in switching the drive shaft 320 between an axially tilted position and an axial position. The number of hollow connecting rods 340 corresponds to the number of first, second, third, or fourth roller brushes, and is used to support the first, second, third, or fourth roller brushes. One end of the hollow connecting rod 340 is connected to the support end plate 330 and extends axially along the first, second, third, or fourth roller brush. When the drive shaft 320 is connected to the first, second, third, or fourth roller brush, the drive shaft 320 can drive the first, second, third, or fourth roller brush to rotate relative to the hollow connecting rod 340 to clean the work surface.

[0092] The support end plate 330 is disposed on a side of the hollow connecting rod 340 away from the roller brush assembly 100 and is configured to support the roller brush assembly 100 and isolate the roller brush assembly 100 from the driving end 210, thereby preventing entangled objects on the surface of the roller brush assembly 100 from entering the driving end 210 and causing the driving end 210 to malfunction. In response to the roller brush assembly 100 being installed on the support frame body 310, the end of the roller brush assembly 100 abuts against the support end plate 330.

[0093] In some embodiments, the support frame body 310 further includes support side plates 350, which are disposed on both sides of the hollow connecting rod 340 and are configured to support the roller brush assembly 100 when the roller brush support frame 300 rotates to an axial position. A protrusion structure 351 is disposed at the root of the support side plates 350. The protrusion structure 351 is located on a side of the support frame body 310 close to the driving end 210 and is configured to engage with the side wall of the roller brush bin 200. Specifically, Figure 9 As shown, the roller brush chamber 200 has a limiting groove 202 on one side near the driving end 210. The closer the limiting groove 202 is to the driving end 210, the deeper it is, making it easier to insert the support frame body 310. In response to the support frame body 310 being assembled in the roller brush chamber 200, the protruding structure 351 is inserted into the limiting groove 202, stabilizing the position of the support frame body 310 in the roller brush chamber 200, thereby ensuring that the roller brush assembly 100 maintains a stable position in the roller brush chamber 200.

[0094] In some embodiments, as Figure 10 As shown, the support frame body 310 further includes a support member 360 , which is an arc-shaped member and is disposed on a side of the support end plate 330 away from the hollow connecting rod 340 .

[0095] In response to the support frame body 310 being mounted on the driving end 210, the support member 360 is connected to the roller brush chamber 200 and is configured to allow the roller brush support frame 300 to rotate around the support member 360. Correspondingly, the roller brush chamber 200 has a limiting hole 203, and the support member 360 passes through the limiting hole 203 and is rotatably connected to the driving end 210 of the roller brush chamber 200.

[0096] Specifically, two limiting holes 203 are provided on the side of the roller brush bin 200 facing the roller brush assembly 100, and the two limiting holes 203 are used to accommodate the support member 360. A through hole 204 is provided between the two limiting holes 203, and the through hole 204 is configured to allow the connecting bolt 370 to be detachably connected to the through hole 204. In response to the support frame body 310 being installed on the driving end 210, the support member 360 is installed inside the limiting hole 203. At this time, the connecting bolt 370 can be passed through the through hole 204 to connect the limiting hole 203 with the support member 360. In response to the movable connection between the limiting hole 203 and the support member 360, the support frame body 310 can rotate relative to the driving end 210 with the connecting bolt 370 as the center, so that the roller brush assembly 100 can switch between the axial position and the axial inclined position.

[0097] In some embodiments, the gear box 400 of the cleaning brush head 1000 may be provided with multiple gears, such as Figure 11As shown, the gear box 400 includes a first gear box 421 and a second gear box 422 , which are respectively arranged on both sides of the roller brush compartment 200 , and the first gear box 421 and the second gear box 422 are connected by a driving connecting rod 423 .

[0098] Specifically, the drive assembly is provided at the drive end 210 and is configured to drive the first gear box 421 to rotate, so that the drive shaft 320 of the drive end 210 drives the roller brush assembly 100 to rotate at high speed to clean the operating surface. The first gear box 421 and the second gear box 422 are connected by a drive connecting rod 423. Under the action of the drive connecting rod 423, the driving force generated by the first gear box 421 is transmitted to the second gear box 422. At this time, the driving force provided by the first gear box 421 and the second gear box 422 causes the first roller brush, the second roller brush, the third roller brush or the fourth roller brush to rotate clockwise or counterclockwise to clean the operating surface. The specific structure of the drive assembly is not described in detail.

[0099] It should be noted that the present disclosure does not limit the driving method of the roller brush assembly 100. It can be driven by a drive assembly or a gear box 400. In addition, the present disclosure does not specifically limit the number of the gear boxes 400. The gear boxes 400 can be provided with one, two, or even more.

[0100] In some embodiments, the roller brush bin 200 includes a dust collection channel 1100, which is arranged on the side close to the free end of the roller brush assembly 100. When the object to be cleaned reaches the vicinity of the free end of the roller brush assembly 100 along the spiral brush member 111, the dust collection channel 1100 is sucked into the dust collection device, thereby improving the cleaning efficiency.

[0101] In some embodiments, the roller brush bin 200 also includes a locking piece. When the connecting end of the roller brush assembly 100 is inserted into the roller brush bin 200, the free end of the roller brush assembly 100 is rotated so as to enter the roller brush bin 200, and then the elastic piece of the roller brush cover cooperates with the locking piece of the roller brush bin 200 to achieve locking, so that the roller brush assembly 100 is stably installed inside the cleaning brush head 1000.

[0102] A second aspect of the present disclosure provides a cleaning device, comprising the cleaning brush head 1000 provided in the first aspect of the present disclosure.

[0103] The cleaning equipment described in the present disclosure, such as a self-propelled robot, a mopping robot, a vacuum cleaner, a floor scrubber, a lawn mower, etc., is not limited to this. Any cleaning equipment that can be equipped with the cleaning brush head 1000 described in the present disclosure can be implemented.
