Cleaning rollers, cleaning equipment and cleaning systems

[0001] Cross-references to related applications

[0002] This application claims priority to Chinese Patent Application No. 202423112065.3, filed on December 16, 2024, the disclosure of which is incorporated herein by reference in its entirety. Technical Field

[0003] This application relates to the field of electrical equipment technology, and more particularly to a cleaning roller brush, cleaning equipment, and cleaning system. Background Technology

[0004] With the development of technology, cleaning equipment has become increasingly common. Most cleaning equipment uses cleaning rollers to clean the floor. As the cleaning roller rotates, the dust-raising components on it can lift dust, hair, and other debris from the surface, allowing the fan in the cleaning equipment to suck the debris into the dust box. During the cleaning process, thread-like debris such as hair can easily become entangled around the outer circumference of the cleaning roller. This entanglement can affect the cleaning function of the roller, and in severe cases, it can even cause blockage and damage to the cleaning equipment.

[0005] In related technologies, a cutting component is provided in the middle of the cleaning roller brush. This cutting component can move relative to the cleaning roller brush in the axial direction of the cleaning roller brush to cut off the entangled material on the cleaning roller brush and reduce the impact of the entangled material on the cleaning roller brush. However, if the cutting area of ​​the cutting component is too long, it will reduce the continuity of the dust-generating component, resulting in poor cleaning effect of the cleaning equipment; if the cutting area of ​​the cutting component is too short, it will reduce the cutting efficiency of the cutting component, causing linear debris to become entangled on the cleaning roller brush, thus affecting the normal operation of the cleaning equipment.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0034] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0036] In this specification, references to "one embodiment," "some embodiments," or simply "embodiment" mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. Furthermore, in one or more embodiments, specific features, structures, or characteristics may be combined in any suitable manner.

[0037] With the development of technology, cleaning equipment has become increasingly common. Most cleaning equipment uses cleaning rollers to clean the floor. As the cleaning roller rotates, the dust-raising components on it can lift dust, hair, and other debris from the surface, allowing the fan in the cleaning equipment to suck the debris into the dust box. During the cleaning process, thread-like debris such as hair can easily become entangled around the outer circumference of the cleaning roller. This entanglement can affect the cleaning function of the roller, and in severe cases, it can even cause blockage and damage to the cleaning equipment.

[0038] In related technologies, a cutting component is provided in the middle of the cleaning roller brush. This cutting component can move relative to the cleaning roller brush in the axial direction of the cleaning roller brush to cut off the entangled material on the cleaning roller brush and reduce the impact of the entangled material on the cleaning roller brush. However, if the cutting area of ​​the cutting component (referring to the range within which the cutting component can cut the entangled material) is too long, it will reduce the continuity of the dust-generating component, resulting in poor cleaning effect of the cleaning equipment; if the cutting area of ​​the cutting component is too short, it will reduce the cutting efficiency of the cutting component, causing linear debris to become entangled on the cleaning roller brush, thus affecting the normal operation of the cleaning equipment.

[0039] In view of the above problems, this application provides a cleaning roller brush, a cleaning device, and a cleaning system, aiming to solve the technical problem that the cleaning effect of the cleaning device and the cutting efficiency of the cutting component cannot be balanced.

[0040] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0041] Please refer to Figures 1 and 3. This application provides a cleaning roller brush, including a housing 1, a dust-raising component 2, and a cutting component 3.

[0042] The housing 1 is provided with a cutting part 11, the length of the cutting part 11 in the axial direction of the housing 1 is one-sixteenth to one-half of the total length of the housing 1 in the axial direction, and a cutting groove 12 is provided on the cutting part 11; the dust-raising component 2 is installed on the outer peripheral surface of the housing 1, and the dust-raising component 2 extends from one end of the housing 1 in the axial direction to the other end of the housing 1 in the axial direction; the cutting component 3 is disposed inside the housing 1, and the cutter 31 of the cutting component 3 is disposed in the cutting groove 12 and can move relative to the cutting part 11 to cut the wrapped material wrapped on the cutting part 11.

[0043] It should be noted that the cleaning principle of the cleaning equipment is as follows: the cleaning roller brush rolls relative to the cleaning surface, and the dust-raising component 2 on the rolling cleaning roller brush scrapes or fans the debris on the cleaning surface, thus raising the debris. The fan in the cleaning equipment generates suction to draw the raised debris into the dust box. Whether the dust-raising component 2 effectively raises the debris during the rolling of the cleaning roller brush is one of the important factors affecting the cleaning effect of the cleaning equipment. When the continuity of the dust-raising component 2 is poor, it cannot maintain constant contact with the cleaning surface or cannot continuously fan the debris during the rolling of the cleaning roller brush, resulting in ineffective debris raising and poor cleaning performance.

[0044] In a cleaning roller brush equipped with a cutting component 3, a cutting groove 12 is required on the housing 1 to accommodate the cutter 31 of the cutting component 3. The cutter 31 cuts the entangled material wrapped around the cutting part 11 at the opening of the cutting groove 12. The dust-raising component 2 needs to avoid the cutting groove 12. When the length of the cutting groove 12 on the cleaning roller brush is long, the cutting area of ​​the cutting component 3 is long and the cutting efficiency is high. However, the length reserved on the cleaning roller brush for setting the dust-raising component 2 is reduced, resulting in poor continuity of the dust-raising component 2. As a result, during the rolling of the cleaning roller brush, the dust-raising component 2 cannot always be in contact with the cleaning surface or cannot always be fanned on the cleaning surface, resulting in some debris on the cleaning surface not being lifted, thus affecting the cleaning effect of the cleaning equipment.

[0045] In the cleaning roller brush provided in this application, the upper limit of the length of the cutter 31 is determined by the length of the cutting part 11. By limiting the length of the cutting part 11 in the axial direction of the housing 1 to between one-sixteenth and one-half of the total length of the housing 1 in the axial direction, and the dust-raising component 2 extending from one end of the housing 1 in the axial direction to the other end of the housing 1 in the axial direction, the length of the cutter 31 can be extended as much as possible without affecting the continuity of the dust-raising component 2. Thus, without affecting the cleaning effect of the cleaning equipment with the cleaning roller brush of this application embodiment, the cutting efficiency of the cutting component 3 can be improved, and the cutting efficiency of the cutting component 3 and the cleaning effect of the cleaning equipment can be balanced.

[0046] Optionally, in some embodiments, the length of the cut portion 11 in the axial direction of the housing 1 is 10mm-100mm.

[0047] It should be noted that the sidewall of the cutting groove 12 has a certain thickness, defined as L thickness. Therefore, in the axial direction of the housing 1, the length of the cutting groove 12 (L cutting groove) is less than the length of the cutting part 11 (L cutting part), and L cutting groove = L cutting part - L thickness.

[0048] It should be noted that the thickness of the sidewall of the cutting groove 12 can be selected according to actual needs.

[0049] Please refer to Figure 1. In some embodiments, the cutting part 11 is provided in the middle of the housing 1 in the axial direction, so that the cleaning roller brush is suitable for cleaning devices with the suction port in the middle.

[0050] Please refer to Figure 1. In some embodiments, the dust-generating assembly 2 includes a dust-generating strip 21. The dust-generating strip 21 includes a first sub-part 211 and a second sub-part 212 connected to each other. The end of the first sub-part 211 away from the second sub-part 212 is located at one end of the housing 1, and the end of the second sub-part 212 away from the first sub-part 211 is located at the other end of the housing 1. The ends of the first sub-part 211 away from the second sub-part 212 and the ends of the second sub-part 212 away from the first sub-part 211 are both located on the same side of the connection between the first sub-part 211 and the second sub-part 212.

[0051] In the above embodiment, the dust-raising strip 21 forms a funnel-shaped space so that when the cleaning roller brush rotates, the dust-raising strip 21 can effectively raise debris on one side of the dust-raising strip 21.

[0052] Please refer to Figure 6. In some embodiments, in the circumferential direction of the housing 1, the connection between the first sub-part 211 and the second sub-part 212 is located on one side of the cutting portion 11. The end of the first sub-part 211 away from the second sub-part 212 is located at one end of the housing 1, and the end of the second sub-part 212 away from the first sub-part 211 is located at the other end of the housing 1. Both the end of the first sub-part 211 away from the second sub-part 212 and the end of the second sub-part 212 away from the first sub-part 211 are located on the other side of the cutting portion 11.

[0053] By adopting the above technical solution, the dust-raising strip 21 forms a funnel-shaped space, and the cutting part 11 is located in the funnel-shaped space formed by the dust-raising strip 21. When the cleaning roller brush rotates, the dust-raising strip 21 can guide the tangled material to the cutting part 11.

[0054] Please refer to Figure 6. In some embodiments, the first sub-part 211 and the second sub-part 212 are spirally arranged, and the first sub-part 211 and the second sub-part 212 rotate in opposite directions, so that the dust strip 21 can guide the linear debris to the connection between the first sub-part 211 and the second sub-part 212 when the cleaning roller brush rotates.

[0055] Because the first sub-part 211 and the second sub-part 212 rotate in opposite directions, during the synchronous rotation of the dust-raising bar 21 and the housing 1, the first sub-part 211 and the second sub-part 212 guide the wound material in opposite directions. This guides the wound material on the housing 1 towards the connection point of the first sub-part 211 and the second sub-part 212, allowing the wound material in other positions on the housing 1 to move as close as possible to the central area of ​​the housing 1. The connection point of the first sub-part 211 and the second sub-part 212 is located on one side of the cutting section 11, allowing the wound material in other positions on the housing 1 to move to the cutting section 11 under the guidance of the dust-raising bar 21. With this arrangement, only one set of cutting components 3 needs to be set on the housing 1. The dust-raising bar 21 guides the wound material in other positions on the housing 1 to the cutting component 3, reducing the number of cutting components 3 and lowering costs.

[0056] During the rotation of the cleaning roller brush by the cleaning equipment, the tangled material rotates along with the housing 1 and wraps around the outer circumference of the housing 1. The tangled material wraps around different positions on the housing 1. Since the position of the cutting part 11 is fixed, the cutting component 3 at the cutting part 11 can only cut the tangled material wrapped around it. The first sub-part 211 and the second sub-part 212 can guide the tangled material to the cutting part 11, allowing the tangled material at different positions on the housing 1 to be guided into the cutting area of ​​the cutting component 3. This enables the cutting component 3 to cut the tangled material, minimizing the tangled material on the housing 1, reducing its impact on the cleaning roller brush, improving the working efficiency of the cleaning roller brush, and extending its service life.

[0057] Please refer to Figure 6. In some embodiments, the dust-generating assembly 2 further includes a guide bar 22. The guide bar 22 includes a first guide portion 221 and a second guide portion 222. The first guide portion 221 and the second guide portion 222 are spaced apart along the axial direction of the housing 1. The cutting portion 11 is located between the first guide portion 221 and the second guide portion 222. The end of the first guide portion 221 that is away from the second guide portion 222 is located at one end of the housing 1, and the end of the second guide portion 222 that is away from the first guide portion 221 is located at the other end of the housing 1. The first guide portion 221 and the second guide portion 222 are both spirally arranged, and the spiral directions of the first guide portion 221 and the second guide portion 222 are opposite.

[0058] Since the first guide portion 221 and the second guide portion 222 rotate in opposite directions, during the synchronous rotation of the guide bar 22 and the housing 1, the first guide portion 221 and the second guide portion 222 guide the winding material in opposite directions, which can guide the winding material on the housing 1 towards the middle area of ​​the housing 1, so that the winding material at other positions on the housing 1 can move as close as possible to the middle area of ​​the housing 1. The cutting portion 11 is disposed between the first guide portion 221 and the second guide portion 222, so that the winding material at other positions on the housing 1 can move to the cutting portion 11 under the guidance of the guide bar 22.

[0059] Please refer to Figure 6. In some embodiments, the cleaning roller brush also includes a guide brush 23, which is installed on the housing 1. The guide brush 23 is used to guide the wrapped material to the cutting section 11. Compared with the guide strip 22, the guide brush 23 is easier to guide the wrapped material, thereby reducing the difficulty of guiding the wrapped material and making it easier to guide the wrapped material to the cutting area of ​​the cutting component 3. This reduces the risk that the wrapped material will always be wrapped around the guide strip 22, thereby reducing the impact of the wrapped material on the operation of the cleaning roller brush.

[0060] Referring to Figure 6, in some embodiments, guide brushes 23 are disposed on both sides of guide strip 22, and each guide brush 23 has multiple bristles arranged spirally in the spiral direction of guide strip 22. The combined effect of the guide brushes 23 and guide strip 22 improves the guiding effect on the tangled material, allowing tangled material at different positions on housing 1 to be guided to cutting assembly 3 as much as possible. This reduces the risk of the tangled material remaining entangled on guide strip 22, thereby reducing the impact of the tangled material on the operation of the cleaning roller brush.

[0061] In some embodiments, the dust-generating component 2 is configured to maintain a preset distance from the cleaning surface at all times when the cleaning equipment is in operation. That is, when the cleaning equipment is in operation, the dust-generating component 2 can maintain a preset distance from the cleaning surface as the cleaning roller brush rotates.

[0062] By adopting the above technical solution, when the cleaning equipment is working, the dust-generating component 2 on the cleaning roller brush can always be in contact with the cleaning surface or the distance between the dust-generating component 2 on the cleaning roller brush and the cleaning surface can be maintained at a preset distance, so as to reduce the noise generated when the cleaning equipment is working.

[0063] Please refer to Figures 1 and 2. In some embodiments, the housing 1 includes two half-shells 13. Each half-shell 13 has a half-hole 131 and a protrusion 132. The protrusion 132 has a receiving groove 1321 that communicates with the half-hole 131. The two half-shells 13 are spliced ​​together by threaded fasteners to form the housing 1. The half-holes 131 on the two half-shells 13 enclose a cavity. The protrusions 132 on the two half-shells 13 are spliced ​​together to form a cutting part 11. The receiving grooves 1321 on the two half-shells 13 are opposite to each other and enclose a cutting groove 12 that communicates the cavity with the outside space. The cutting component 3 is disposed in the cavity, and part of the cutting component is movably disposed between the two protrusions 132.

[0064] Referring to Figure 1, optionally, in some embodiments, the housing 1 is provided with two dust-raising strips 21, and each half-shell 13 is provided with one dust-raising strip 21. The connection between the first sub-part 211 and the second sub-part 212 of the dust-raising strip 21 is located on one side of the protrusion 132, and both ends of the dust-raising strip 21 extend to the connection between the two half-shells 13. When the cleaning equipment is working, as the cleaning roller brush rotates, the dust-raising strip 21 on the cleaning roller brush can always contact the cleaning surface, or the distance between the dust-raising strip 21 on the cleaning roller brush and the cleaning surface remains unchanged.

[0065] Referring to Figure 6, in some embodiments, the housing 1 is provided with two dust-raising strips 21 and two guide strips 22. The connection between the first sub-part 211 and the second sub-part 212 of the dust-raising strip 21 is located on one side of the protrusion 132 on one of the half-shells 13, and the dust-raising strip 21 passes around the protrusion 132 and extends to the other half-shell 13 through the connection between the two half-shells 13. Each half-shell 13 is provided with one dust-raising strip 21. When the cleaning equipment is working, as the cleaning roller brush rotates, the dust-raising strip 21 or guide strip 22 on the cleaning roller brush can contact the cleaning surface, or the distance between the dust-raising strip 21 or guide strip 22 on the cleaning roller brush and the cleaning surface is a preset distance.

[0066] According to the design requirements of the cleaning equipment, in some embodiments, when the cleaning equipment is placed on the cleaning surface (e.g., the ground), the dust-generating component 2 is interference-fitted with the cleaning surface, that is, as the cleaning roller brush rotates, the dust-generating component 2 can always maintain a preset distance from the cleaning surface, which means that the dust-generating component 2 can always be in contact with the cleaning surface.

[0067] In the above embodiments, the dust-generating component 2 is always in contact with the cleaning surface to prevent impurities from leaking between the dust-generating component 2 and the cleaning surface, thereby enhancing the cleaning efficiency of the cleaning equipment.

[0068] Optionally, in the above embodiments, the interference fit between the dust-generating component 2 and the cleaning surface is 0.1mm-0.5mm.

[0069] According to the design requirements of the cleaning equipment, in some embodiments, when the cleaning equipment is placed on the cleaning surface (e.g., the ground), the dust-generating component 2 is spaced apart from the cleaning surface. That is, as the cleaning roller brush rotates, the dust-generating component 2 can always maintain a preset distance from the cleaning surface. This means that the dust-generating component 2 can always be spaced apart from the cleaning surface, and the distance between the dust-generating component 2 and the cleaning surface is maintained at a preset distance.

[0070] In the above embodiments, the dust-generating component 2 is always spaced apart from the contact surface to reduce the noise generated when the cleaning equipment is working.

[0071] Optionally, in the above embodiments, the distance between the dust-generating component 2 and the cleaning surface is 0.2mm-0.3mm.

[0072] Please refer to Figure 2. In some embodiments, the protrusions 132 on the two half-shells 13 are provided with a plurality of toothed grooves 1322 that are spaced apart in the axial direction of the shell 1.

[0073] When the entangled material is wrapped around the cutting part 11 on the cleaning roller brush of the above embodiment, the entangled material is accommodated in the tooth groove 1322 on the protrusion 132 on the two half shells 13, so that the entangled material is horizontally placed at the opening of the cutting groove 12. When the cutting component 3 moves relative to the cutting part 11, the cutting component 3 can cut off the entangled material horizontally placed at the opening of the cutting groove 12.

[0074] Please refer to Figures 3 and 4. In some embodiments, the cutting assembly 3 further includes a drive group 32 and a transmission group 33. The cutter 31 includes a first moving blade 311 and a second moving blade 312. Under the drive of the drive group 32, the transmission group 33 can drive the first moving blade 311 and the second moving blade 312 to move relative to the cutting part 11 along the axial direction of the housing 1, and the moving directions of the first moving blade 311 and the second moving blade 312 are opposite.

[0075] In the above embodiment, the first moving blade 311 and the second moving blade 312 move in opposite directions, so that the first moving blade 311 and the second moving blade 312 move alternately, which can improve the cutting efficiency of the cutter 31.

[0076] Please refer to Figures 3 and 4. In some embodiments, the first moving blade 311 and the second moving blade 312 are arranged at a distance in the radial direction of the housing 1, and both the first moving blade 311 and the second moving blade 312 are provided with a plurality of cutting teeth arranged at a distance in the axial direction of the housing 1. When the first moving blade 311 and the second moving blade 312 move alternately, the cutting teeth on the first moving blade 311 and the cutting teeth on the second moving blade 312 can cooperate to cut the wrapped material, so as to improve the cutting efficiency of the cutter 31.

[0077] In some embodiments, the number of cutting teeth on the first moving blade 311 and the number of cutting teeth on the second moving blade 312 are both greater than or equal to 5.

[0078] It should be noted that sufficient space needs to be reserved in the cutting groove 12 for the first moving blade 311 and the second moving blade 312. That is, in the axial direction of the housing 1, the length of the first moving blade 311 and the length of the second moving blade 312 are both less than the length of the cutting groove 12. The length of the reserved space in the axial direction of the housing 1 is defined as L_allowance, and the length of the first moving blade 311 and the second moving blade 312 = L_cutting portion - L_thickness - L_allowance.

[0079] Optionally, the length of the first moving blade 311 in the axial direction of the housing 1 is 2mm-92mm, and / or the length of the second moving blade 312 in the axial direction of the housing 1 is 2mm-92mm.

[0080] Please refer to Figure 4. In some embodiments, the cutting part 11 has two cutting grooves 12 that are radially connected to the housing 1. There are two sets of cutters 31, which are correspondingly arranged in the cutting grooves 12. The two sets of cutters 31 are connected to the transmission group 33.

[0081] In the above embodiment, the cutting effect can be improved by increasing the number of cutters 31.

[0082] Please refer to Figure 4. In some embodiments, the transmission assembly 33 includes a first transmission rod 331, a second transmission rod 332, and a third transmission rod 333. Two first moving blades 311 are rotatably connected to both ends of the first transmission rod 331, and two second moving blades 312 are rotatably connected to both ends of the second transmission rod 332. The first moving blades 311 and the second moving blades 312, which are located on both sides of the axial direction of the housing, are rotatably connected to both ends of the third transmission rod 333. The end of the third transmission rod 333 connected to the second moving blades 312 is located on the side of the end of the third transmission rod 333 connected to the first moving blades 311 that is close to the first transmission rod 331. The drive assembly 32 is connected to the first transmission rod 331 and is used to drive the first transmission rod 331 to reciprocate along the axial direction of the housing 1.

[0083] In the above embodiments, since both first moving blades 311 are rotatably connected to the first transmission rod 331, when the drive assembly 32 drives the first transmission rod 331 to reciprocate along the axial direction of the housing 1, the two first moving blades 311 can move simultaneously and in different directions. Since the first moving blades 311 and the second moving blades 312 located on both sides of the axial direction of the housing are rotatably connected to the third transmission rod 333, one of the moving first moving blades 311 can drive the third transmission rod 333 to rotate, and the rotating third transmission rod 333 can drive one of the two second moving blades 312 to move. Since both second moving blades 312 are rotatably connected to the second transmission rod 332, under the drive of the third transmission rod 333, the two second moving blades 312 can move simultaneously and in different directions.

[0084] Furthermore, in the above embodiment, since the end of the third transmission rod 333 connected to the second moving blade 312 is located on the side of the end of the third transmission rod 333 connected to the first moving blade 311 close to the first transmission rod 331, when the drive assembly 32 drives the first transmission rod 331 to swing back and forth along the axial direction of the housing 1, the first moving blade 311 and the second moving blade 312 can move alternately.

[0085] Please refer to Figure 4. In some embodiments, the middle part of the first transmission rod 331 is rotatably disposed on the housing 1 so as to limit the position of the first transmission rod 331, so that the first transmission rod 331 can be stably rotated around the middle part of the first transmission rod 331.

[0086] Please refer to Figure 4. In some embodiments, the middle part of the second transmission rod 332 is rotatably disposed on the housing 1 so as to limit the position of the second transmission rod 332, so that the second transmission rod 332 can be stably rotated around the middle part of the second transmission rod 332.

[0087] Please refer to Figure 4. In some embodiments, the transmission assembly 33 further includes a first stabilizer 334 and a second stabilizer 335. Two first moving blades 311 are rotatably connected to both ends of the first stabilizer 334, and two second moving blades 312 are rotatably connected to both ends of the second stabilizer 335.

[0088] In the above embodiments, the first stabilizing rod 334 and the first transmission rod 331 cooperate to enable the first moving blade 311 to move more stably, and the second stabilizing rod 335 and the second transmission rod 332 cooperate to enable the second moving blade 312 to move more stably.

[0089] Please refer to Figure 4. In some embodiments, the drive assembly 32 includes a cam 321. A limiting part is provided on the first transmission rod 331. The cam 321 is connected to the limiting part. The cam 321 can rotate radially around the housing 1. The cam 321 abuts against two opposite side walls of the limiting part. As the cam 321 rotates, the first transmission rod 331 can swing back and forth along the axial direction of the housing 1.

[0090] In the above embodiments, the limiting part is a limiting cavity.

[0091] Referring to Figure 5, in some embodiments, the drive assembly 32 further includes a drive member, a transmission shaft 323, a driven gear 324, a first bevel tooth 325, a second bevel tooth 326, and a rotating shaft 327. The drive member is fixedly mounted on the housing 1, and a drive gear 322 is provided inside the drive member. The rotation shaft 327 of the drive gear 322 is parallel to the axial direction of the housing 1, and the drive gear 322 can rotate with the housing 1 around the central axis of the housing 1. The driven gear 324 and the first bevel tooth 325 are coaxially and fixedly connected to both ends of the transmission shaft 323, respectively. The central axis of the transmission shaft 323 coincides with the central axis of the housing 1, and the driven gear 324 meshes with the drive gear 322. The second bevel tooth 326 and the cam 321 are both coaxially and fixedly arranged with the rotating shaft 327, and the rotating shaft 327 is rotatably arranged on the housing 1. The second bevel tooth 326 meshes with the first bevel tooth 325.

[0092] By adopting the above technical solution, when the cleaning roller brush rotates, the driving gear 322 rotates around the central axis with the housing 1, so that the driven gear 324 drives the transmission shaft 323 and the first bevel gear 325 to rotate, thereby causing the second bevel gear 326, the cam 321 and the rotating shaft 327 to rotate, and then causing the cam 321 to drive the first transmission rod 331 to swing.

[0093] Please refer to Figure 4. In some embodiments, cam 321 is an eccentric wheel.
