Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a cleaning component, cleaning equipment, and cleaning system for a cleaning device. Background Technology

[0002] With the advancement of technology and changes in people's lifestyles, intelligent cleaning equipment is gradually entering thousands of households and becoming an indispensable part of people's lives.

[0003] In related technologies, cleaning equipment (such as robot vacuums) usually uses a roller brush to clean the floor. Most robot vacuums use a single roller brush for cleaning. This method can easily cause hair to get tangled on the roller brush, making it difficult for the hair to be sucked into the dustbin. Therefore, users need to manually remove the hair from the roller brush afterward, which reduces cleaning efficiency. Utility Model Content

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of the present invention is to provide a cleaning component for a cleaning device that can ensure the cleaning coverage of the cleaning component and reduce the probability of hair entanglement, thereby improving the cleaning effect.

[0041] The embodiments of this utility model are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0042] The following is for reference. Figures 1-8 The cleaning component 100 according to an embodiment of the present invention ensures cleaning coverage and reduces the probability of hair entanglement, thereby improving cleaning effect. Here, the cleaning device 200 can be a handheld vacuum cleaner, canister vacuum cleaner, upright vacuum cleaner, or bin vacuum cleaner with a corresponding structure equipped with a roller brush, as long as it can provide suction to suck up dust and debris; this application embodiment does not limit this.

[0043] Combination Figures 1-8 As shown, the cleaning device 200 according to the first aspect embodiment of the present invention includes a cleaning component 100 comprising a drive mechanism 1, a first roller brush 2, and a second roller brush 3. The drive mechanism 1 provides power to at least one of the first roller brush 2 and the second roller brush 3 for axial (i.e., axial movement of the first roller brush 2), thereby causing the first roller brush 2 and the second roller brush 3 to move closer or further apart axially. The first roller brush 2 and the second roller brush 3, by rolling on the cleaning surface, lift up dirt adhering to them during their movement, thus cleaning the dirt.

[0044] Specifically, the first roller brush 2 and the second roller brush 3 are spaced apart along the axial direction of the first roller brush 2, and at least one of the first roller brush 2 and the second roller brush 3 is connected to the drive mechanism 1 so as to move along the axial direction of the first roller brush 2 under the drive action of the drive mechanism 1.

[0045] Specifically, the roller brushes (at least one of the first roller brush 2 and the second roller brush 3) connected to the drive mechanism 1 can move along the axial direction of the first roller brush 2. Thus, by controlling the drive mechanism 1, the first roller brush 2 and the second roller brush 3 can move closer to or further away from each other. For example, if the first roller brush 2 is connected to the drive mechanism 1 and the position of the second roller brush 3 remains unchanged, then the first roller brush 2 can move away from or closer to the position of the second roller brush 3 under the drive of the drive mechanism 1. Alternatively, if both the first roller brush 2 and the second roller brush 3 are connected to the drive mechanism 1, then the first roller brush 2 and the second roller brush 3 can move away from or closer to each other under the drive of the drive mechanism 1.

[0046] Specifically, under the driving action of the drive mechanism 1, the minimum distance d between the first roller brush 2 and the second roller brush 3 along the axial direction of the first roller brush 2 satisfies the relationship: 2mm≤d≤6mm. For example, d can be 2mm, 2.5mm, 3mm, 5mm, and 6mm, and is not limited to these.

[0047] The above arrangement can limit the minimum distance between the first roller brush 2 and the second roller brush 3 along the axial direction of the first roller brush 2. While maintaining the minimum distance, the first roller brush 2 and the second roller brush 3 can still complete the rotation cleaning work normally.

[0048] In this design, the minimum distance between the first roller brush 2 and the second roller brush 3 along the axial direction of the first roller brush 2 is smaller. Compared with a traditional single roller brush, this design can ensure the cleaning coverage effect of the two roller brushes on the cleaning surface (for example, the blank cleaning area between the first roller brush 2 and the second roller brush 3 is very small, or, through another embodiment of this case, there is no blank cleaning area between the first roller brush 2 and the second roller brush 3). It can also facilitate the removal of hair that is simultaneously wrapped on the two roller brushes, thereby improving the cleaning effect.

[0049] Furthermore, to ensure the cleaning coverage of the first roller brush 2 and the second roller brush 3 when performing cleaning work on the cleaning surface, the distance between the first roller brush 2 and the second roller brush 3 is as small as possible. This reduces the blank areas that the cleaning component 100 fails to cover in a single cleaning path, thereby ensuring the cleaning ability of the cleaning component 100. The gap between the first roller brush 2 and the second roller brush 3 also facilitates the removal of tangled hair at the gap, thus reducing the probability of hair entanglement. Additionally, under the driving action of the drive device, the first roller brush 2 and the second roller brush 3 can move away from each other, increasing the distance between them. This creates a pulling effect on the hair on both roller brushes, loosening or breaking the hair, further reducing the probability of hair entanglement on the roller brushes.

[0050] Furthermore, since hair may also get tangled in the small gap between the two roller brushes (i.e., it may get tangled on the end or on the brush or the structure that compensates for the gap), the hair in the gap can be released by moving the first roller brush 2 and the second roller brush 3 away from each other, thus solving the problem of hair easily getting tangled on the roller brushes.

[0051] Therefore, by setting a first roller brush 2 and a second roller brush 3 that can move relative to each other along the axial direction, the cleaning coverage of the cleaning component 100 can be guaranteed on the one hand, and the probability of hair entanglement can be reduced on the other hand, thereby improving the cleaning effect and thus improving the user experience.

[0052] According to some optional embodiments of the present invention, combined with Figures 3-7 As shown, the first roller brush 2 and the second roller brush 3 are both connected to the drive mechanism 1. Under the driving action of the drive mechanism 1, the first roller brush 2 and the second roller brush 3 move towards or away from each other along the axial direction of the first roller brush 2.

[0053] The drive mechanism 1 can drive both the first roller brush 2 and the second roller brush 3. This allows the first roller brush 2 and the second roller brush 3 to move closer or further away from each other more quickly within the same time. On the other hand, it also allows the two roller brushes to move a greater distance away from each other without increasing the overall size, thereby improving their ability to pull hair.

[0054] Specifically, in combination Figures 3-7 As shown, the drive mechanism 1 includes a first drive mechanism 11 and a second drive mechanism 12. The first drive mechanism 11 is connected to the first roller brush 2, and the second drive mechanism 12 is connected to the second roller brush 3. The first drive mechanism 11 and the second drive mechanism 12 are spaced apart and are independent of each other.

[0055] As described above, on the one hand, it is convenient for the first drive mechanism 11 and the second drive mechanism 12 to independently control the first roller brush 2 and the second roller brush 3 respectively (even if one drive mechanism 1 fails, the other drive mechanism 1 can still continue to work), thereby increasing the reliability of the cleaning assembly 100; on the other hand, it is also convenient for operators to perform individual maintenance and replacement of one of the first drive mechanism 11 and the second drive mechanism 12, thereby improving the ease of disassembly and assembly of the drive mechanism 1.

[0056] Furthermore, combined Figures 3-7As shown, both the first drive mechanism 11 and the second drive mechanism 12 include a drive motor 13 and a first transmission mechanism 14. The first transmission mechanism 14 is connected to the corresponding first roller brush 2 and second roller brush 3. The first transmission mechanism 14 cooperates with the drive motor 13. Under the driving action of the drive motor 13, the first transmission mechanism 14 drives the corresponding first roller brush 2 and second roller brush 3 to move along the axial direction of the first roller brush 2.

[0057] For example, the first transmission mechanism 14 is connected to the first roller brush 2. The drive motor 13 can transmit the driving force to the first transmission mechanism 14. Under the action of the driving force, the first transmission mechanism 14 drives the first roller brush 2 to move along its axial direction, thus ensuring that the first roller brush 2 can smoothly achieve the effect of axial movement.

[0058] Specifically, in combination Figures 3-6 As shown, the drive motor 13 is a rotary motor; the first transmission mechanism 14 includes a lead screw 141 and a lead screw sleeve 142. The lead screw 141 is connected to the drive motor 13, and the lead screw sleeve 142 is connected to the corresponding first roller brush 2 and second roller brush 3. The lead screw sleeve 142 is threadedly engaged with the lead screw 141. The rotary motor can convert electrical energy into rotational mechanical energy through the principle of electromagnetic induction.

[0059] For example, the lead screw sleeve 142 is connected to the first roller brush 2, and the drive motor 13 drives the lead screw 141 to rotate. The lead screw 141 and the lead screw sleeve 142 are threaded together. In this way, the lead screw sleeve 142 can be moved along the thread by driving the lead screw 141 to rotate (that is, the relative rotational motion of the lead screw sleeve 142 is converted into linear motion along the axial direction of the lead screw 141), thereby achieving the effect of the lead screw sleeve 142 driving the first roller brush 2 to extend or retract along the axial direction of the lead screw 141.

[0060] Furthermore, combined Figures 3-6 As shown, the cleaning assembly 100 also includes a first roller brush bracket 4 and a second roller brush bracket 5. The first roller brush 2 is rotatably disposed on the first roller brush bracket 4. The first roller brush bracket 4 is connected to the lead screw sleeve 142 of the first drive mechanism 11. The second roller brush 3 is rotatably disposed on the second roller brush bracket 5. The second roller brush bracket 5 is connected to the lead screw sleeve 142 of the second drive mechanism 12.

[0061] It is understandable that the first roller brush bracket 4 and the second roller brush bracket 5 can serve as mounting support carriers for the first roller brush 2 and the second roller brush 3, respectively. The first roller brush 2 is fixedly connected to the first roller brush bracket 4, which is in turn fixedly connected to the lead screw sleeve 142 of the first drive mechanism 11. This allows the lead screw sleeve 142 to drive the first roller brush bracket 4 to move synchronously under the drive of the first drive mechanism 11, thus achieving the effect of axial translation of the first roller brush 2. The second roller brush 3 is fixedly connected to the second roller brush bracket 5, which is in turn fixedly connected to the lead screw sleeve 142 of the second drive mechanism 12. This allows the lead screw sleeve 142 to drive the second roller brush bracket 5 to move synchronously under the drive of the second drive mechanism 12, thus achieving the effect of axial translation of the second roller brush 3.

[0062] In summary, the first roller brush 2 and the second roller brush 3 can utilize the principle of screw and nut cooperation to convert the rotational motion of the drive motor 13 into the axial translational motion of the two roller brushes.

[0063] Specifically, in combination Figures 3-7 As shown, the cleaning assembly 100 also includes a roller brush housing 6, which has a receiving cavity 61. The first roller brush 2 and the second roller brush 3 are disposed in the receiving cavity 61. The drive motor 13 in the first drive mechanism 11 and the second drive mechanism 12 is disposed in the roller brush housing 6, and the drive motor 13 is located above the receiving cavity 61.

[0064] The first roller brush 2 and the second roller brush 3 are located in the receiving cavity 61 of the roller brush housing 6. The roller brush housing 6 can protect the first roller brush 2 and the second roller brush 3. The drive motor 13 in the first drive mechanism 11 and the second drive mechanism 12 is located above the roller brush housing 6. This can make full use of the space above the roller brush housing 6 and avoid occupying additional space of the cleaning component 100 in the axial direction of the first roller brush 2, thereby improving the structural compactness and the rationality of the spatial arrangement.

[0065] Furthermore, combined Figures 3-6 As shown, the roller brush housing 6 has a dust collection port 62 that communicates with the receiving cavity 61, and the drive motors 13 in the first drive mechanism 11 and the second drive mechanism 12 are located on opposite sides of the dust collection port 62.

[0066] Understandably, the first roller brush 2 and the second roller brush 3 inside the receiving cavity 61 adhere to the dirt on the cleaning surface by rotating, and the dust collection port 62 is negatively pressured by the suction action of the suction device. This can create a suction effect on the dirt attached to the first roller brush 2 and the second roller brush 3, thereby smoothly guiding the dirt to the dust collection port 62, and then sucking the dirt into the special collection structure.

[0067] The drive motors 13 in the first drive mechanism 11 and the second drive mechanism 12 are located on opposite sides of the dust collection port 62. This avoids the risk of interference between the first drive mechanism 11 and the second drive mechanism 12 and the air passage of the dust collection port 62, thereby improving the rationality of the spatial arrangement.

[0068] Furthermore, the dust collection port 62 is located in the middle of the roller brush housing 6 along the axial direction of the first roller brush 2. This allows dirt on the first roller brush 2 and the second roller brush 3 to move naturally towards the adsorption area (i.e., the dust collection port 62). That is, the dirt moves towards the suspension end of the first roller brush 2 and the second roller brush 3 (in this application, the end where the first roller brush 2 and the first roller brush bracket 4 are connected is defined as the fixed end, and the end of the first roller brush 2 extending towards the second roller brush 3 is defined as the suspension end, and the same applies to the second roller brush 3). This allows the dirt to move away from the fixed end of the first roller brush 2 and the second roller brush 3, thereby effectively avoiding the problem of dust and hair accumulating at the fixed end and effectively solving the problem of hair getting tangled on one side of the fixed end, thus maintaining the cleaning effect of the cleaning component 100 for a long time.

[0069] Specifically, in combination Figures 3-6 As shown, the cleaning assembly 100 also includes a motor bracket 7. The roller brush housing 6 is provided with fixed seats 63 arranged circumferentially around the receiving cavity 61 above the receiving cavity 61. The motor bracket 7 is mounted on the fixed seats 63, and a positioning groove is formed between the fixed seats 63. The drive motor 13 is mounted on the motor bracket 7, and the drive motor 13 is located in the positioning groove.

[0070] Understandably, the motor bracket 7 can provide support and protection for the drive motor 13. Part of the outer surface of the roller brush shell 6 is arc-shaped, which can better match the rotation path of the first roller brush 2 and the second roller brush 3. The roller brush shell 6 is provided with fixed seats 63 at intervals along its own receiving cavity 61. The fixed seats 63 form positioning grooves for cooperating with the drive motor 13. This can limit the drive motor 13, thereby preventing the risk of the drive motor 13 shaking and falling off, and ensuring the positional stability of the drive motor 13.

[0071] Furthermore, the drive motor 13 is a rotary motor; the cleaning assembly 100 also includes a second transmission mechanism, which is connected to the drive motor 13 and the first transmission mechanism 14 respectively, and the second transmission mechanism transmits the rotational motion of the drive motor 13 to the first transmission mechanism 14.

[0072] For example, the second transmission mechanism may include a speed reducer that can convert the high-speed, low-torque output of the drive motor 13 into a low-speed, high-torque output. In this way, the output speed of the drive motor 13 can be reduced by the second transmission mechanism, thereby increasing the output torque of the drive motor 13 to the first transmission mechanism 14, thus improving the driving capability of the drive motor 13, reducing the noise level of the drive motor 13 during operation, and improving the user experience.

[0073] Specifically, in combination Figures 3-6 and Figure 8 As shown, the first transmission mechanism 14 includes a rotating shaft 143 with an external thread, and the rotating shaft 143 is disposed on the corresponding first roller brush 2 and second roller brush 3; the second transmission mechanism includes a first transmission component, a second transmission component, and a limiting component. The first transmission component is connected to the drive motor 13, and the second transmission component is in transmission cooperation with the first transmission component. The second transmission component forms a threaded hole, which is in cooperation with the external thread. The limiting component is disposed on the second transmission component. After the rotating shaft 143 rotates relative to the second transmission component to a preset position, the limiting component is in limiting cooperation with the rotating shaft 143, so that the second transmission component rotates synchronously with the corresponding first roller brush 2 or second roller brush 3 through the rotating shaft 143.

[0074] It is understood that the fixed ends of the first roller brush 2 and the second roller brush 3 are respectively connected to the rotating shaft 143. The drive motor 13 transmits the driving force to the first transmission component. The first transmission component transmits the driving force to the second transmission component through transmission cooperation. The threaded hole on the second transmission component has an internal thread, which is threadedly engaged with the external thread on the rotating shaft 143. Since the position of the second transmission component along the axial direction of the first roller brush 2 remains unchanged, and is affected by the friction generated by the first roller brush 2 and the second roller brush 3 against the cleaning surface, the first roller brush 2 and the second roller brush 3 will not rotate radially synchronously with the second transmission component, but will move linearly along the axial direction with the mutually engaged threads. Thus, by controlling the rotation direction of the drive motor 13, the effect of the first roller brush 2 and the second roller brush 3 moving closer to each other and further away from each other can be achieved.

[0075] The second transmission component is equipped with a limiting component. When the rotating shaft 143 rotates to a preset position relative to the second transmission component, the limiting component and the rotating shaft 143 are engaged in an axial upper limit cooperation. This can form an axial limiting effect on the rotating shaft 143, preventing the rotating shaft 143 from continuing to move along the original movement trend. This forces the rotating shaft 143 to rotate synchronously with the second transmission component, thereby achieving the effect of the rotating shaft 143 driving the corresponding first roller brush 2 and second roller brush 3 to rotate synchronously.

[0076] In addition, the limiting member is fixedly connected to one end of the second transmission member away from the fixed end of the first roller brush 2 and the second roller brush 3, so that the limiting member can limit the extreme position of the rotating shaft 143 relative to the outer side of the second transmission member for axial linear movement.

[0077] Furthermore, combined Figure 2 , Figure 3 and Figure 7 As shown, the cleaning assembly 100 also includes a roller brush housing 6, which has a receiving cavity 61. The first roller brush 2 and the second roller brush 3 are disposed in the receiving cavity 61. The first drive mechanism 11 and the second drive mechanism 12 both include a first magnetic element and a second magnetic element. The first magnetic element is disposed in the roller brush housing 6, and the second magnetic element is disposed in the corresponding first roller brush 2 and second roller brush 3. One of the first magnetic element and the second magnetic element is an electromagnetic element. When the electromagnetic element is energized, the first magnetic element and the second magnetic element generate magnetic force to drive the corresponding first roller brush 2 and the second roller brush 3 to move along the axial direction of the first roller brush 2.

[0078] The first roller brush 2 and the second roller brush 3 are located in the receiving cavity 61 of the roller brush shell 6, and the roller brush shell 6 can protect the first roller brush 2 and the second roller brush 3.

[0079] Optionally, the first magnetic element of the first driving mechanism 11 is disposed on the brush shell 6, and the second magnetic element of the first driving mechanism 11 is disposed on the first brush 2. The first magnetic element is an electromagnetic element, which can generate a magnetic field when energized (that is, it does not generate a magnetic field when not energized). This facilitates the generation of magnetic attraction between the first magnetic element and the second magnetic element by utilizing the magnetic field principle of opposite poles attracting each other, thereby successfully achieving the effect of the first driving mechanism 11 driving the first brush 2 to move along its axial direction toward the position of the first magnetic element in the brush shell 6.

[0080] Alternatively, the first magnetic element of the second drive mechanism 12 is disposed on the brush shell 6, and the second magnetic element of the second drive mechanism 12 is disposed on the second brush 3. The second magnetic element is an electromagnetic element, which can generate a magnetic field when energized (that is, it does not generate a magnetic field when not energized). This facilitates the generation of magnetic attraction between the second magnetic element on the second brush 3 and the first magnetic element on the brush shell 6 using the principle of magnetic field attraction between opposite poles, thereby successfully achieving the effect of the second drive mechanism 12 driving the second brush 3 to move along its axial direction toward the position of the first magnetic element on the brush shell 6.

[0081] Specifically, both the first drive mechanism 11 and the second drive mechanism 12 further include an elastic element, one end of which abuts against the brush shell 6, and the other end of which abuts against the corresponding first brush 2 and second brush 3.

[0082] It is understandable that, since the elastic element abuts between the roller brush shell 6 and the corresponding first roller brush 2 and second roller brush 3, when the external force on the elastic element is less than the elastic force it generates, the first roller brush 2 and the second roller brush 3 will move closer to each other under the action of the elastic restoring force of the elastic element.

[0083] For example, the first magnetic component of the first driving mechanism 11 is disposed on the brush shell 6, and the second magnetic component of the first driving mechanism 11 is disposed on the first brush 2. The first magnetic component is an electromagnetic component, which can generate a magnetic field when energized (that is, it does not generate a magnetic field when not energized). This facilitates the generation of a magnetic attraction force between the first and second magnetic components using the magnetic field principle of opposite poles attracting each other (at this time, the magnetic attraction force is greater than the elastic restoring force), thereby smoothly achieving the effect of the first driving mechanism 11 driving the first brush 2 to move along its axial direction toward the position of the first magnetic component in the brush shell 6. When the energization of the first magnetic component is stopped, the magnetic attraction force between the first and second magnetic components disappears. At this time, the first brush 2 is subjected to an elastic restoring force from the elastic component in the axial direction, and the first brush 2 will move toward the direction of the second brush 3.

[0084] Furthermore, the driving mechanism 1 includes a third magnetic element and a fourth magnetic element. The third magnetic element is disposed on the first roller brush 2, and the fourth magnetic element is disposed on the second roller brush 3. Both the third and fourth magnetic elements are electromagnetic elements. When the electromagnetic element is energized, the third and fourth magnetic elements generate magnetic force to drive the corresponding first roller brush 2 and second roller brush 3 to move along the axial direction of the first roller brush 2.

[0085] Optionally, the third and fourth magnetic components are respectively disposed on the first roller brush 2 and the second roller brush 3. The third and fourth magnetic components can generate a magnetic field when energized (that is, they do not generate a magnetic field when not energized). This allows the third and fourth magnetic components to generate a magnetic repulsion force by utilizing the principle of like poles repelling each other after being energized, thereby smoothly achieving the effect of the drive mechanism 1 driving the first roller brush 2 and the second roller brush 3 to move in opposite directions along the axial direction.

[0086] In addition, the drive mechanism 1 also includes an elastic element. One end of the elastic element abuts against the brush shell 6, and the other end of the elastic element abuts against the corresponding first brush 2 and second brush 3. Since the elastic element abuts between the brush shell 6 and the corresponding first brush 2 and second brush 3, when the external force on the elastic element (such as the magnetic repulsion force generated by the third magnetic element and the fourth magnetic element when energized) is less than the elastic force generated by itself, the first brush 2 and the second brush 3 will move towards each other under the action of the elastic restoring force of the elastic element.

[0087] According to some optional embodiments of the present invention, combined with Figure 2 , Figure 3 and Figure 7 As shown, the cleaning assembly 100 also includes a roller brush housing 6, which has a receiving cavity 61 in which the first roller brush 2 and the second roller brush 3 are disposed; wherein, the end of the roller brush housing 6 is provided with a clearance space, which is used to avoid the corresponding first roller brush 2 and second roller brush 3.

[0088] Specifically, the first roller brush 2 and the second roller brush 3 are located in the receiving cavity 61 of the roller brush housing 6. The roller brush housing 6 can protect the first roller brush 2 and the second roller brush 3. The roller brush housing 6 is provided with a clearance space at the end along the axial direction of the first roller brush 2. The clearance space can be a storage space for the first roller brush 2 and the second roller brush 3 to move away from each other along the axial direction, thereby avoiding the risk of interference and collision between the first roller brush 2 and the second roller brush 3 and the end of the roller brush housing 6, and thus improving the rationality of its arrangement.

[0089] According to some optional embodiments of the present invention, the end faces of the first roller brush 2 and the second roller brush 3 facing each other are arranged in parallel, and the end faces of the first roller brush 2 and the second roller brush 3 facing each other form an angle with the axis of the first roller brush 2, the angle being an acute angle or a right angle.

[0090] Optionally, combined Figure 2 and Figure 3 As shown, the end faces of the first roller brush 2 and the second roller brush 3 are parallel to each other, and an angle α, where α is an acute angle, is formed between the end faces of the first roller brush 2 and the axis of the first roller brush 2. This ensures that when the end faces of the first roller brush 2 and the second roller brush 3 are projected radially, they form at least a partial overlap. This guarantees that the first roller brush 2 and the second roller brush 3 form a continuous cleaning coverage contact surface along the axial direction of the first roller brush 2, avoiding any uncleaned blank areas during the cleaning process. This reduces hair entanglement while ensuring the cleaning effect of the roller brushes. When the first roller brush 2 and the second roller brush 3 are closest to each other, the two roller brushes rotate at the same frequency.

[0091] In particular, in the above embodiments, the first roller brush 2 and the second roller brush 3 form at least a partially overlapping area when projected radially in the two states of being closest and furthest apart. This ensures that the cleaning component 100 will not have a blank cleaning area in either of the above states, thereby improving its cleaning effect.

[0092] Alternatively, combine Figure 7 As shown, the end faces of the first roller brush 2 and the second roller brush 3 facing each other form an angle β with the axis of the first roller brush 2, where β is a right angle. This can reduce hair entanglement and simplify the manufacturing process of the first roller brush 2 and the second roller brush 3, thereby improving its practicality.

[0093] In this embodiment, when the first roller brush 2 and the second roller brush 3 are individually connected to the independent first drive mechanism 11 and the second drive mechanism 12, the first drive mechanism 11 and the second drive mechanism 12 can selectively control the first roller brush 2 and the second roller brush 3 to rotate at different frequencies. Thus, even when the first roller brush 2 and the second roller brush 3 are closest to each other, they can still pull the hairs simultaneously adhering to both roller brushes, effectively reducing the probability of hair entanglement. Furthermore, when the first roller brush 2 and the second roller brush 3 are closest to each other, the two roller brushes can selectively rotate at the same frequency or at different frequencies.

[0094] The cleaning device 200 according to the second aspect of the present invention includes the cleaning component 100 of the cleaning device 200 of the above embodiment. Thus, the cleaning device 200 having the cleaning component 100 can reduce the probability of hair getting tangled on the roller brush, thereby improving the cleaning effect of the cleaning device 200.

[0095] The cleaning system according to a third aspect of the present invention includes a base station 300 and a cleaning device 200 as described above, wherein the cleaning device 200 selectively interfaces with the base station 300.

[0096] For example, when the cleaning device 200 returns to the base station 300, the cleaning device 200 can dock with the base station 300 and control the first roller brush 2 and the second roller brush 3 of the cleaning component 100 to move in opposite directions, thereby creating a pulling and loosening effect on the hair on the two roller brushes, which makes it easier for the base station 300 to collect the hair on the roller brushes.
