[0033] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The cutting component 1 of the cleaning device according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0035] like Figures 1-3 , Figure 5 As shown, the cutting assembly 1 of the cleaning device according to an embodiment of the present invention includes a housing 10, a moving blade 20, and a driving device.

[0036] The housing 10 defines a receiving cavity 11 with an opening 111. The movable blade 20 is rotatably disposed in the housing 10. A driving device is used to drive the movable blade 20 to rotate. The movable blade 20 switches between a first state and a second state. When the movable blade 20 is in the first state, it is housed in the receiving cavity 11. At this time, the cleaning equipment can be used normally to clean the surface to be cleaned. This avoids the movable blade 20 affecting the rolling of the roller brush 62 in the cleaning equipment and prevents the movable blade 20 from scratching the user when the user cleans the cleaning equipment. This improves the safety of using the cleaning equipment.

[0037] When the moving blade 20 is in the second state, at least part of the moving blade 20 extends from the opening 111 to the outside of the receiving cavity 11. At this time, the moving blade 20 can cut fibrous debris such as hair outside the receiving cavity 11. For example, when the driving device drives the moving blade 20 to rotate, the moving blade 20 can cut off fibrous debris such as hair wrapped around the roller brush 62 to clean the roller brush 62 in the cleaning equipment, so as to avoid the fibrous debris such as hair wrapped around the roller brush 62 from affecting the cleaning of the surface to be cleaned by the roller brush 62.

[0038] Specifically, when the driving device drives the moving blade 20 to rotate and at least a portion of the moving blade 20 extends from the opening 111 to the outside of the receiving cavity 11, the moving blade 20 rotates towards the roller brush 62. When the moving blade 20 is retracted into the receiving cavity 11, the moving blade 20 rotates away from the roller brush 62. During this process, the moving blade 20 can pull and pull fibrous debris such as hair wrapped around the roller brush 62, so that there is a certain force between the moving blade 20 and the fibrous debris such as hair, so that the moving blade 20 can cut the fibrous debris located in its rotation path when rotating, so as to cut the long and thin fibrous debris such as hair into fragments, so that it can no longer be wrapped around the roller brush 62, thereby achieving the cleaning of the roller brush 62.

[0039] Therefore, the moving blade 20 of the cutting assembly 1 of the cleaning device according to the present invention can cut the hair located on its rotation path when it rotates. By cutting the fibrous debris on the roller brush 62, the fibrous debris will not continue to wrap around the roller brush 62 due to its shorter length, so as to facilitate the cleaning of fibrous debris such as hair and ensure the normal use of the roller brush 62.

[0040] The cutting component 1 of a cleaning device according to a specific embodiment of the present invention is described below with reference to the accompanying drawings.

[0041] In some specific embodiments of the present invention, such as Figures 1-3 , Figure 5 As shown, the cutting assembly 1 of the cleaning equipment includes a housing 10, a moving blade 20, and a drive unit.

[0042] In some embodiments of the present invention, such as Figure 3As shown, the portion of the movable blade 20 extending out of the receiving cavity 11 is formed in a hook shape, which makes it easier for the movable blade 20 to hook onto fibrous waste such as hair when it rotates, thereby making it easier for the movable blade 20 to cut the fibrous waste such as hair.

[0043] Specifically, in the embodiment where the cutting assembly 1 is used to cut fibrous waste such as hair wrapped around the roller brush 62, when the moving blade 20 hooks the fibrous waste such as hair and rotates away from the roller brush 62, since a part of the fibrous waste such as hair is wrapped and fixed on the roller brush 62, when the moving blade 20 moves the fibrous waste such as hair, a force is generated between the moving blade 20 and the fibrous waste such as hair, so that the moving blade 20 can cut the fibrous waste such as hair.

[0044] Furthermore, by controlling the length of the moving blade 20 extending out of the receiving cavity 11 and controlling the distance between the moving blade 20 and the roller brush 62, the moving blade 20 can hook the hair and other fibrous debris tightly wrapped around the roller brush, so as to thoroughly clean the hair wrapped around the roller brush 62.

[0045] Specifically, by using the hook-shaped portion of the movable blade 20 extending out of the receiving cavity 11, even if fibrous debris such as hair is tightly wrapped around the roller brush 62 of the cleaning equipment, the movable blade 20 can hook and pull the fibrous debris wrapped around the roller brush 62 to cut the fibrous debris wrapped around the roller brush 62, while avoiding the movable blade 20 from scratching the roller brush 62.

[0046] In some embodiments, such as Figure 3 As shown, the hook-shaped extension direction is consistent with the rotation direction of the moving blade 20, so that when the driving device drives the moving blade 20 to rotate, the moving blade 20 can hook and pull fibrous waste, thereby improving the cutting efficiency of the moving blade 20.

[0047] In some embodiments of the present invention, such as Figure 2 , Figure 3 As shown, the moving blade 20 includes a rotating part 21 and a blade body part 22. The rotating part 21 is rotatably disposed in the receiving cavity 11. The blade body part 22 is connected to the rotating part 21 so as to rotate together with the rotating part 21. The blade body part 22 has two oppositely arranged side edges. One end of the two side edges is connected to the rotating part 21 and the other end is connected to form a blade tip at the other end of the blade body part 22. The blade tip is used to cut fibrous waste such as hair or to hook and pull fibrous waste such as hair.

[0048] In some embodiments, such as Figure 2 , Figure 3As shown, both sides of the blade body 22 are curved and bend in the same direction, so that the tip of the blade body 22 is hook-shaped. When the moving blade 20 rotates, the tip of the moving blade 20 can hook onto fibrous waste such as hair, thereby facilitating the cutting of fibrous waste such as hair.

[0049] In other embodiments, both sides of the blade body 22 are formed in an arc shape and the bending directions are opposite; or, one side of the blade body 22 is formed in an arc shape and the other side is formed in a straight line shape, with the center of the arc shape located on the side of the arc shape away from the straight line shape; or, one side of the blade body 22 is formed in an arc shape and the other side is formed in a straight line shape, with the center of the arc shape located on the side of the arc shape facing the straight line shape.

[0050] In some embodiments, the cutting edge of the moving blade 20 is located at at least one side edge so that the moving blade 20 can cut fibrous debris such as hair it comes into contact with when rotating.

[0051] Specifically, when the moving blade 20 rotates and pulls fibrous waste such as hair, there is an interaction force between the moving blade 20 and the fibrous waste such as hair, and when the fibrous waste such as hair comes into contact with the blade of the moving blade 20, the moving blade 20 can easily cut the fibrous waste such as hair, so as to cut the fibrous waste such as hair into fragments.

[0052] In some embodiments, both sides of the blade body 22 are arc-shaped and bend in the same direction, so that the tip of the blade body 22 is hook-shaped. The rotation direction of the blade body 22 is consistent with the extension direction of the side edge. A cutting edge is provided on the side edge near the center of the arc shape so that the moving blade 20 can easily cut fibrous waste such as hair when rotating.

[0053] Specifically, the side edge closest to the center of the arc is called the first side edge, and the other side edge is called the second side edge. When the moving blade 20 rotates, the tip of the blade body 22 hooks onto fibrous waste such as hair. The fibrous waste such as hair will adhere to the first side edge. Therefore, the blade is set at the first side edge to facilitate the moving blade 20 to cut the fibrous waste such as hair.

[0054] In some embodiments of the present invention, such as Figure 3 As shown, there are multiple moving blades 20, which are arranged along the extension direction of the opening 111, so as to use multiple moving blades 20 to cut fibrous waste in different areas of the same plane, thus improving the cutting efficiency of the cutting assembly 1.

[0055] In some optional embodiments of the present invention, the extension direction of the opening 111 is perpendicular to the extension direction of the rotation axis of the moving blade 20, so that the rotation plane of the moving blade 20 is parallel to the extension direction of the opening 111. In the extension direction of the opening 111, the area swept by two adjacent moving blades 20 during rotation partially overlaps, so as to ensure the cutting effect of multiple moving blades 20 on fibrous waste such as hair and reduce the probability of cutting dead angles.

[0056] In some embodiments, such as Figure 2 , Figure 3 As shown, the opening 111 extends in the left-right direction, the rotation axis of the moving blade 20 extends in the front-back direction, and multiple moving blades 20 are arranged in the left-right direction (it should be understood that the above direction limitation is only for the convenience of describing the attached figure and will not limit the actual setting position and direction of the cutting component 1 of the cleaning equipment). Multiple moving blades 20 rotate in the same plane and the area swept by two adjacent moving blades 20 during rotation partially overlaps, so as to ensure the cutting effect of multiple moving blades 20 on fibrous waste such as hair, and avoid that fibrous waste such as hair in some areas is not cut.

[0057] For example, the cutting component 1 is used to cut fibrous waste such as hair wrapped around the roller brush 62. The roller brush 62 extends axially in the left and right direction, and multiple moving blades 20 are arranged in the left and right direction to ensure that the area swept by the multiple moving blades 20 can cover the axial length of the roller brush 62, thereby ensuring the cleaning effect of the moving blades 20 on the roller brush 62.

[0058] Since the moving blade 20 rotates, a cutting dead angle similar to a triangular area will be formed between the areas swept by two adjacent moving blades 20, so that the areas swept by two adjacent moving blades 20 partially overlap, which makes it easier to reduce the area of ​​the cutting dead angle, thereby reducing the cutting dead angle on the roller brush 62 and improving the cleaning effect of the moving blade 20 on the roller brush 62.

[0059] In some specific embodiments of the present invention, the line connecting the end of the movable blade 20 away from its rotation center to the rotation center is the first line. In the extension direction of the opening 111, the first lines connecting two adjacent movable blades 20 are parallel to each other or set at an angle, so as to use multiple movable blades 20 to cut fibrous waste such as hair, so that multiple movable blades 20 can cut fibrous waste such as hair outside the receiving cavity 11 simultaneously or sequentially, so as to achieve a better cutting effect.

[0060] The distance between two adjacent moving blades 20 should be greater than the length of the first connecting line, so as to avoid collisions between two adjacent moving blades 20 when the driving device drives multiple moving blades 20 to rotate at the same time.

[0061] In some embodiments, the first line connecting two adjacent moving blades 20 is parallel to each other. When the driving device drives the multiple moving blades 20 to rotate, the multiple moving blades 20 are simultaneously in the first state or the second state, so that they can simultaneously cut fibrous waste such as hair outside the receiving cavity 11 or be simultaneously collected in the receiving cavity 11, so that the multiple moving blades 20 together cut the fibrous waste such as hair, so that the fibrous waste such as hair can be cut into shorter fragments, and the cut hair will not continue to be wrapped around the roller brush 62.

[0062] In other embodiments, such as Figure 2 As shown, the first lines connecting two adjacent moving blades 20 are arranged at an angle, dividing the multiple moving blades 20 into a first moving blade assembly and a second moving blade assembly. The first moving blade assembly includes multiple first moving blades 201, and the first lines connecting the multiple first moving blades 201 are parallel to each other. The second moving blade assembly includes multiple second moving blades 202, and the first lines connecting the multiple second moving blades 202 are parallel to each other. The first lines connecting the first moving blades 201 and the first lines connecting the second moving blades 202 are arranged at an angle. When the driving device drives the multiple moving blades 20 to rotate, the first moving blade assembly and the second moving blade assembly extend successively from the opening 111 of the receiving cavity 11 to cut fibrous waste such as hair outside the receiving cavity 11. This improves the cutting effect of the cutting assembly on fibrous waste.

[0063] In some examples, there are cutting dead angles in the areas swept by two adjacent moving blades 20, so that the two adjacent moving blades 20 clean the hair wrapped on the roller brush 62 one after the other. The moving blade 20 that cuts hair and other fibrous waste first can move the hair from the cutting dead angle into the cutting area, so that the moving blade 20 that cuts hair and other fibrous waste later can cut the fibrous waste smoothly, which facilitates the improvement of cleaning effect.

[0064] Specifically, when hair is entangled in the cutting dead corner, when the first moving blade 201 extends out of the receiving cavity to clean the hair and other fibrous debris on the roller brush 62, the first moving blade 201 can cut a portion of the hair entangled on the roller brush 62. At this time, some hair falls off the roller brush 62 and can move the hair located in the cutting dead corner to the area swept by the second moving blade 202. When the second moving blade 202 rotates, it can cut this portion of hair, so that the multiple moving blades 20 can fully cut the hair entangled on the roller brush 62, thereby improving the cleaning effect of the cutting assembly 1 on the roller brush.

[0065] In some examples, such as Figure 5As shown, the included angle between the first connecting lines of two adjacent moving blades 20 is 90°, so that the first moving blade assembly and the second moving blade assembly can be in the first state at the same time, that is, multiple first moving blades 201 and multiple second moving blades 202 are simultaneously housed in the receiving cavity 11. At this time, all moving blades 20 are housed in the receiving cavity 11 to avoid the moving blades 20 scratching the user and to improve the safety of the cutting assembly 1.

[0066] In some alternative embodiments of the present invention, such as Figure 2 , Figure 4 As shown, the driving device includes a driving component 31 and a transmission mechanism 32. The transmission mechanism 32 includes a transmission component 321 and multiple rotating components 322. The multiple rotating components 322 are arranged along the extension direction of the opening 111. Adjacent rotating components 322 are connected by transmission component 321. The driving component 31 is used to drive the transmission component 321 or the rotating component 322 to move. The moving blade 20 is fixed to the rotating component 322 to rotate together with the rotating component 322. When the driving component 31 is working, the transmission component 321 and the multiple rotating components 322 can work simultaneously, thereby driving the multiple moving blades 20 to rotate together. The multiple moving blades 20 are used to cut fibrous waste such as hair outside the receiving cavity 11.

[0067] In some embodiments, the cutting assembly 1 includes two moving blades 20, and the transmission mechanism 32 includes a transmission member 321 and two rotating members 322. The transmission member 321 meshes with the two rotating members 322 respectively, and the driving member 31 is used to drive the transmission member 321 or the rotating members 322 to rotate, thereby realizing the synchronous rotation of the transmission member 321 and the two rotating members 322 to drive the two moving blades 20 to rotate.

[0068] In other embodiments, such as Figure 2 As shown, the cutting assembly 1 includes multiple moving blades 20, the number of moving blades 20 is greater than 2, the transmission mechanism 32 includes multiple transmission components 321 and multiple rotating components 322, a transmission component 321 is provided between two adjacent rotating components 322 and all of them are engaged with the transmission component 321, the driving component 31 cooperates with one of the transmission components 321 to drive the transmission component 321 to rotate, when the driving component 31 drives the transmission component 321 to rotate, it can simultaneously drive multiple transmission components 321 and multiple rotating components 322 to rotate together, thereby driving multiple moving blades 20 to rotate together.

[0069] In some specific embodiments of the present invention, such as Figure 3 As shown, the transmission component 321 is rotatably disposed within the housing 10. The rotation center of the transmission component 321 is located on one side of the line connecting the rotation centers of two adjacent rotating components 322, so as to compactly arrange the transmission component 321 and the rotating component 322, thereby reducing the space occupied by the transmission mechanism 32.

[0070] like Figure 4 As shown, in this embodiment, the transmission mechanism 32 includes multiple transmission components 321 and multiple rotating components 322. The multiple rotating components 322 are arranged at intervals in the left-right direction. The multiple transmission components 321 are located on one side of the line connecting the rotation centers of two adjacent rotating components 322. The multiple transmission components 321 are arranged at intervals in the left-right direction. This arrangement is to compactly arrange the multiple transmission components 321 and multiple rotating components 322, thereby reducing the space occupied by the transmission mechanism 32.

[0071] In some embodiments of the present invention, such as Figure 2 As shown, the cutting assembly 1 of the cleaning equipment also includes a fixed blade 40, which is fixed to the housing 10 and partially extends out of the receiving cavity 11 from the opening 111. When the moving blade 20 is in the second state, the blade of the fixed blade 40 is in contact with the blade of the moving blade 20 so that the fixed blade 40 and the moving blade 20 form a scissor structure, which can cut fibrous waste such as hair.

[0072] Specifically, when the fibrous waste is hard, it is not easy to cut the fibrous waste by relying solely on the moving blade 20. By setting a fixed blade 40, when the moving blade 20 rotates, the moving blade 20 can hook the fibrous waste onto the blade of the fixed blade 40, so that the scissor structure formed by the fixed blade 40 and the moving blade 20 can cut the fibrous waste.

[0073] In some embodiments, such as Figure 2 As shown, the housing 10 includes a first housing portion 101 and a second housing portion 102. The first housing portion 101 and the second housing portion 102 are fixedly connected and define a receiving cavity 11 with an opening 111. The first housing portion 101 is provided with a plurality of first connecting shafts 121 and a plurality of second connecting shafts 122. The plurality of first connecting shafts 121 are arranged at intervals in the left-right direction, and the plurality of second connecting shafts 122 are arranged at intervals in the left-right direction. The plurality of second connecting shafts 122 are located on one side of the first connecting shafts 121. A rotating member 322 is rotatably disposed on the first connecting shaft 121 so as to rotatably dispose of the rotating member 322 within the receiving cavity 11. A transmission member 321 is rotatably disposed on the second connecting shaft 122 so as to rotatably dispose of the transmission member 321 within the receiving cavity 11.

[0074] The movable blade 20 is fixed to the rotating member 322 and located on the side of the rotating member 322 away from the first housing 101, so as to avoid the movable blade 20 interfering with the first connecting shaft 121 and the second connecting shaft 122 when rotating.

[0075] In some embodiments, the movable blade 20 is fixed to the rotating member 322 and faces the side of the second housing portion 102, and the fixed blade 40 is fixed to the side of the second housing portion 102 facing the first housing portion 101, so that the movable blade 20 and the fixed blade 40 are in contact, thereby enabling the movable blade 20 and the fixed blade 40 to cut fibrous waste such as hair.

[0076] The cleaning apparatus according to an embodiment of the present invention is described below. The cleaning apparatus according to an embodiment of the present invention includes a cutting component 1 according to the cleaning apparatus of the above embodiment of the present invention.

[0077] According to the cleaning device of the present invention, by utilizing the cutting component 1 of the cleaning device of the present invention described above, the moving blade 20 of the cutting component 1 can cut the hair located on its rotation path when rotating. By cutting the fibrous debris on the roller brush 62, the fibrous debris will not continue to wrap around the roller brush 62 due to the shortening of its length, so as to facilitate the cleaning of fibrous debris such as hair and ensure the normal use of the roller brush 62.

[0078] In some embodiments of the present invention, the cleaning device defines a cleaning chamber 61 and the bottom of the cleaning device has a dust inlet 611 communicating with the cleaning chamber 61. The cleaning chamber 61 is provided with a rotatable roller brush 62. The roller brush 62 includes a rotating rod 621 and a plurality of bristles 622. The plurality of bristles 622 are disposed on the peripheral wall of the rotating rod 621. When the cleaning device is working, the roller brush 62 rotates to clean the surface to be cleaned using the plurality of bristles 622.

[0079] In the second state, the moving blade 20 is inserted between the multiple bristles 622 and spaced apart from the rotating rod 621. This prevents the moving blade 20 from scratching the rotating rod 621 when cutting fibrous debris such as hair entangled on the bristles 622. The axial direction of the roller brush 62 is aligned with the extending direction of the opening 111, allowing the moving blade 20 to have a wider contact range with the bristles 622, thus enabling it to effectively cut the fibrous debris such as hair entangled on the bristles 622. Specifically, the movable blade 20 is inserted into the bristles 622 so that the movable blade 20 can cut the fibrous waste such as hair tightly wrapped in the bristles 622 and cut the fibrous waste near the rotating rod 621, which facilitates the improvement of the cutting effect of the cutting component 1 on the fibrous waste and improves the cutting efficiency of the cutting component 1 on the fibrous waste.

[0080] It needs to be explained here that when the moving blade 20 is in the second state and the length of the moving blade 20 extending out of the receiving cavity 11 is the longest, the end of the moving blade 20 away from the rotation center is always spaced apart from the rotating rod 621, so as to avoid the moving blade 20 scratching the rotating rod 621 during the rotation of the moving blade 20.

[0081] like Figure 6 , Figure 7 As shown, in this embodiment, the cutting assembly 1 includes a plurality of moving blades 20, which are arranged along the extension direction of the opening 111, so that the axial direction of the roller brush 62 is consistent with the extension direction of the opening 111, so that the sweeping area of ​​the plurality of moving blades 20 can cover the axial length of the roller brush 62, thereby ensuring the cleaning effect of the moving blades 20 on the roller brush 62.

[0082] In some embodiments, the rotation axis of the moving blade 20 is perpendicular to the extension direction of the opening 111, and the rotation plane of the moving blade 20 is parallel to the extension direction of the opening 111, so as to increase the overlap area of ​​the brush bristles 622 and the sweeping range of the moving blade 20, so that the moving blade 20 can fully cut the fibrous debris such as hair wrapped around the brush bristles 622.

[0083] In some alternative embodiments of the present invention, such as Figure 6 As shown, the cleaning equipment also has a suction channel 63 and a suction port 64. The suction port 64 connects the cleaning chamber 61 and the suction channel 63. When the cleaning equipment is working, the debris on the surface to be cleaned enters the cleaning chamber 61 through the dust inlet 611 and enters the suction channel 63 through the suction port 64. The cutting component 1 is located above the roller brush 62 and close to the suction port 64. In this way, after the cutting component 1 cuts the hair and other fibrous debris on the roller brush 62 into small pieces, the small pieces of debris can easily enter the suction channel 63 through the suction port 64, preventing the small pieces of debris from falling onto the surface to be cleaned and affecting the cleaning of the surface by the cleaning equipment.

[0084] In some alternative embodiments of the present invention, such as Figure 6 As shown, the roller brush 62 includes multiple rows of bristles 622 and rubber strips 65. A single row of bristles 622 extends along the axial direction of the rotating rod 621, and multiple rows of bristles 622 are arranged circumferentially along the rotating rod 621. A rubber strip 65 is provided between two adjacent rows of bristles 622. The rubber strip 65 is used to reduce the gap between the cleaning device and the surface to be cleaned, so as to improve the suction power of the cleaning device, so that the cleaning device can pick up the garbage on the surface to be cleaned, thereby achieving the cleaning of the surface to be cleaned.

[0085] Other configurations and operations of the cleaning equipment according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0086] The cleaning system 7 according to an embodiment of the present invention is described below. Figure 10As shown, the cleaning system 7 according to an embodiment of the present invention includes a cleaning robot 71 and a clothing handling device 72. The cleaning robot 71 is a cleaning device according to the above embodiment of the present invention. The clothing handling device 72 integrates a cleaning base station. The cleaning base station defines a placement cavity 721. The placement cavity 721 is used to accommodate the cleaning robot 71 and to reserve space for the cleaning robot 71 to dock. By integrating the cleaning robot 71 and the clothing handling device 72 together, it is easy to reduce the space occupied by the cleaning robot 71 and the clothing handling device 72 in the room.

[0087] The cleaning robot 71 can be a sweeping robot, which can be placed in the placement cavity 721, so that the cleaning base station can charge the cleaning robot 71 or clean and dry the roller brush 62 of the cleaning robot 71 in the placement cavity 721; or, the cleaning robot 71 can also be a floor scrubber, at least part of which can be placed in the placement cavity 721, so that the cleaning base station can charge the cleaning robot 71 or clean and dry the roller brush 62 of the cleaning robot 71 in the placement cavity 721.

[0088] According to the cleaning system of the present invention, by integrating the cleaning robot 71 and the clothing handling device 72 together, it is easy to reduce the space occupied by the cleaning robot 71 and the clothing handling device 72 in the room.

[0089] In some embodiments of the present invention, the placement cavity 721 is located below the clothing handling device 72 and has a front opening, so that the cleaning robot 71 can be conveniently moved into the placement cavity 721 from the front opening after cleaning the floor.

[0090] The following describes a control method for a cleaning device according to an embodiment of the present invention. The cleaning device is the cleaning device described in the above embodiment of the present invention, such as... Figure 8 As shown, the control method includes the following steps: S1: Receive cleaning instructions for the roller brush; S2: Control the working state of the roller brush and drive device to clean the roller brush using the moving blades; The roller brush 62 and the drive unit do not work simultaneously to prevent the moving blade 20 from cutting the bristles 622.

[0091] It should be explained here that the roller brush 62 and the drive device not working at the same time includes the roller brush 62 rotating while the drive device is not working, the roller brush 62 stopping rotating while the drive device is working, and the roller brush 62 stopping rotating while the drive device is not working.

[0092] Specifically, when the received cleaning instruction is to clean the roller brush 62, the roller brush 62 stops rotating, and the drive device drives the moving blade 20 to rotate, so that the moving blade 20 can cut the hair wrapped around the roller brush 62, thereby cleaning the roller brush 62. The drive device starts working after the roller brush 62 stops rotating to avoid the moving blade 20 and the roller brush 62 rotating simultaneously, thus preventing the moving blade 20 from cutting the bristles 622.

[0093] According to the control method of the cleaning equipment of the present invention, the drive device starts working after the roller brush 62 stops rotating, so as to avoid the moving blade 20 and the roller brush 62 rotating at the same time, and to prevent the moving blade 20 from cutting the bristles 622.

[0094] In some embodiments of the present invention, controlling the operating state of the roller brush and the drive device to clean the roller brush using a moving blade includes: Control the drive unit to operate and detect the status of the moving blade; Once the operating time of the drive device reaches the preset time and the moving blade is in the first state, the drive device is controlled to stop working.

[0095] Specifically, when the roller brush 62 stops rotating and the control drive device is working, the drive device stops working when the duration of the drive device driving the moving blade 20 to rotate exceeds the preset duration and the moving blade 20 is stored in the receiving cavity 11. At this time, the moving blade 20 completes the cleaning of the upper part of the roller brush 62 directly opposite it.

[0096] In some embodiments, the housing 10 is provided with a sensor for sensing the position of the moving blade 20. When the working time of the drive device reaches a preset time and the sensor senses that the moving blade 20 is in a first state, the drive device is controlled to stop working.

[0097] In some optional embodiments of the present invention, after the control drive device stops working, the method further includes: Control the rotation of the roller brush until the rotation angle of the roller brush reaches the first preset angle; The control drive device is activated again until the operating time of the drive device reaches the preset time again and the moving blade is in the first state.

[0098] The movable blade 20 can cut fibrous debris such as hair in a certain area of ​​the roller brush 62 when it rotates. Specifically, after the roller brush 62 stops rotating, the drive device works for the first time. At this time, the drive device drives the movable blade 20 to rotate to cut the fibrous debris wrapped around a certain area of ​​the roller brush 62. After the drive device works for more than a preset time and the movable blade 20 is in the first state, the drive device stops working. At this time, the roller brush 62 is controlled to rotate a first preset angle and then stops rotating. The drive device works for the second time to cut the fibrous debris wrapped around other areas of the roller brush 62.

[0099] Among them, such as Figure 9 As shown, by repeating the above process, the fibrous waste wrapped around the roller brush 62 circumferentially is fully cut, and the longer fibrous waste is cut into fragments to facilitate the cleaning of the fibrous waste.

[0100] In some specific embodiments of the present invention, the first preset angle is less than 360°, wherein the smaller the first preset angle, the more precisely the cutting component 1 cuts the fibrous waste wrapped on the roller brush 62.

[0101] For example, the first preset angle can be 30°, 45°, 90°, 135°, 150° or 180°.

[0102] In some specific embodiments of the present invention, controlling the operating state of the roller brush 62 and the driving device to clean the roller brush 62 using the moving blade 20 further includes: Detect the total rotation angle of the roller brush relative to its initial position or the number of operations of the drive device; When the total rotation angle reaches the second preset angle or the number of operations reaches the preset number, the control drive device stops working.

[0103] This ensures that the cutting component 1 fully cuts the fibrous waste that is wrapped around the roller brush 62 in the circumference, making it easier to reduce cutting dead angles.

[0104] It needs to be explained here that the rotation of the roller brush 62 includes a first rotation state and a second rotation state. The first rotation state is that the roller brush 62 rotates to clean the surface to be cleaned, and the second rotation state is that the roller brush 62 rotates at a first preset angle to adjust the area that the cutting component 1 can cut in the circumferential direction of the roller brush 62.

[0105] When the driving device drives the moving blade 20 to rotate, the roller brush 62 is stopped. When the roller brush 62 is in the second rotating state and the total rotation angle of the roller brush 62 reaches the second preset angle or the number of working times of the driving device reaches the preset number, the driving device stops working. At this time, the cutting component 1 has completed the cleaning of the roller brush 62, and then the roller brush 62 can be used normally. Alternatively, the roller brush 62 can be in the first rotating state to clean the surface to be cleaned.

[0106] In some embodiments, the second preset angle is greater than or equal to 360°, so that the total angle of rotation of the roller brush 62 relative to the moving blade 20 is greater than or equal to 360°, thereby ensuring that the moving blade 20 fully cuts the fibrous waste wrapped around the roller brush 62 in a circumferential direction.

[0107] In some embodiments, the first preset angle is 30° and the second preset angle is 360°, and the drive device operates 12 times during the cleaning process of the moving blade 20 on the roller brush 62. In other embodiments, the first preset angle is 30° and the second preset angle is 390°, and the drive device operates 13 times during the cleaning process of the moving blade 20 on the roller brush 62. In still other embodiments, the first preset angle is 45° and the second preset angle is 360°, and the drive device operates 8 times during the cleaning process of the moving blade 20 on the roller brush 62. In still other embodiments, the first preset angle is 90° and the second preset angle is 360°, and the drive device operates 4 times during the cleaning process of the moving blade 20 on the roller brush 62.
