Description

[Technical Field]

[0001] This disclosure belongs to the field of electrical equipment technology, and particularly relates to a cleaning roller brush, cleaning equipment and cleaning system. [Previous Technology]

[0002] With the development of technology, cleaning equipment has become increasingly popular. Floor cleaning in homes and offices is gradually being handled by cleaning equipment. Most cleaning equipment uses cleaning rollers to achieve its cleaning function. During the cleaning process, hair and other thread-like objects on the floor can easily become entangled around the outer circumference of the cleaning roller. If there is a lot of entangled material, it can affect the cleaning function, or even clog the cleaning roller and damage the machine. [Summary of the Invention]

[0003] This disclosure claims priority to Chinese Patent Application No. 202410698269.5, filed on May 31, 2024, entitled “A Cleaning Roller Brush, Cleaning Equipment and Cleaning System”, and Chinese Patent Application No. 202421236752.3, filed on May 31, 2024, entitled “A Cleaning Roller Brush, Cleaning Equipment and Cleaning System”, the entire contents of which are incorporated herein by reference.

[0004] This disclosure aims to at least partially solve the technical problem of poor cleaning effect of cleaning roller brushes. To this end, this disclosure provides a cleaning roller brush, cleaning equipment, and cleaning system.

During the rotation of the housing, linear entanglements such as hair will wrap around the housing along the rotation direction of the housing.

[0034] With the development of science and technology, cleaning equipment has become increasingly popular. Most cleaning equipment achieves its floor cleaning function through cleaning roller brushes. During the cleaning process, hair and other thread-like objects on the floor can easily become entangled on the outer circumference of the cleaning roller brush. If there is a lot of entangled material, it will at least affect the cleaning function, and at worst, it will cause the cleaning roller brush to become clogged and damage the machine. Therefore, this disclosure embodiment provides a cleaning roller brush 100, a cleaning device 1, and a cleaning system. The cleaning roller brush 100, cleaning device 1, and cleaning system provided in this disclosure embodiment can automatically clean the entangled material on the cleaning roller brush 100 during the cleaning process, thereby reducing the impact of the entangled material on the cleaning roller brush 100, improving the working effect of the cleaning roller brush 100, and increasing the service life of the cleaning roller brush 100.

[0035] The technical solution disclosed herein is described below with reference to the accompanying drawings and specific embodiments.

[0036] Please refer to Figure 1. A cleaning roller brush 100 is provided according to an embodiment of this disclosure. The cleaning roller brush 100 is installed on the cleaning device 1 and is mainly used for cleaning objects to be cleaned. During the cleaning process, the cleaning roller brush 100 can automatically clean up the tangled objects wrapped around it, thereby reducing the impact of the tangled objects on the cleaning roller brush 100, improving the working effect of the cleaning roller brush 100, and extending its service life.

[0037] Referring to Figures 1-3, in some embodiments, the cleaning roller brush 100 includes: a housing 110, a cutting assembly 120, and a cleaning section 150 mounted on the housing 110. The cutting assembly 120 is connected to the housing 110 and is rotatable relative to the housing 110. The cutting direction of the cutting assembly 120 is set at an angle to the rotation direction of the housing 110.

[0038] In some embodiments, the housing 110 is the main body 10 of the entire cleaning roller brush 100 and provides a mounting base for structures such as the cleaning section 150 and the cutting assembly 120. The housing 110 is generally cylindrical and can be connected to the drive mechanism of the cleaning device 1, thereby being able to rotate relative to the main body 10 of the cleaning device 1 under the drive of the drive mechanism. The cleaning section 150 is mounted on the outer peripheral surface of the housing 110 and is mainly used to contact the ground during the rotation of the brush section to clean the ground.

[0039] In some embodiments, the cleaning section 150 may be elongated. The cleaning section 150 may be arranged along the extending direction of the housing 110. The cleaning section 150 may be arranged in a straight line in the extending direction of the housing 110, or in an arc shape in the extending direction of the housing 110, or in a spiral shape in the extending direction of the housing 110, and there is no limitation on this.

[0040] Multiple cleaning sections 150 may be provided. Multiple cleaning sections 150 are arranged at intervals on the circumference of the housing 110. Any two cleaning sections 150 may have the same shape or different shapes.

[0041] During the rotation of the cleaning roller brush 100 driven by the cleaning device 1, linear entanglements such as hair will wrap around the outer circumference of the housing 110 as the housing 110 rotates, meaning the winding direction of the entanglement is the same as the rotation direction of the housing 110. In some embodiments, the cutting direction of the cutting component 120 (the Y direction shown in Figures 1 and 2) is set at an angle to the rotation direction of the housing 110 (the X direction shown in Figures 1 and 2), indicating that the cutting direction of the cutting component 120 is different from the rotation direction of the housing 110. Since the winding direction of the entanglement is the same as the rotation direction of the housing 110, it can be known that the cutting direction of the cutting component 120 is different from the winding direction of the entanglement, meaning that the cutting direction of the cutting component 120 is different from the length direction of the linear entanglement. The cutting direction of the cutting component 120 is different from the length direction of the wrapped material. Therefore, during the rotation of the cutting component 120 relative to the housing 110, the cutting motion of the cutting component 120 has at least a component along the radial direction of the wrapped material, enabling the cutting component 120 to cut the wrapped material and minimize its entanglement on the housing 110. This reduces the impact of the wrapped material on the cleaning roller brush 100, improves the working effect of the cleaning roller brush 100, and extends the service life of the cleaning roller brush 100.

[0042] Referring to Figure 3, in some embodiments, the cutting assembly 120 includes a transmission member 130 and a cutting member 140 that is pulvinctly connected to the transmission member 130. The transmission member 130 is fixedly connected to the housing 110. The cutting member 140 is rotatably connected to the housing 110.

[0043] The transmission component 130 is fixed to the housing 110 and is connected to the cutting component 140 in a transmission manner. During the rotation of the housing 110 by the drive mechanism of the cleaning device 1, the transmission component 130 rotates with the housing 110, enabling the transmission component 130 to drive the cutting component 140 to rotate relative to the housing 110. In some embodiments, the transmission component 130 primarily functions to drive the cutting component 140 to rotate relative to the housing 110. The cutting component 140 is mainly used for cutting tangled materials.

[0044] In some embodiments, the transmission member 130 is arranged along the extension direction of the housing 110, and the cutting direction of the cutting member 140 is set at an angle to the rotation direction of the housing 110.

[0045] The cutting direction of the cutting element 140 can be considered as the rotation direction of the cutting element 140 relative to the housing 110. The cutting direction of the cutting element 140 is set at an angle to the rotation direction of the housing 110, that is, the rotation direction of the cutting element 140 is different from the rotation direction of the housing 110. During the rotation of the housing 110, thread-like entanglements such as hair will wrap around the housing 110 as the housing 110 rotates. Since the rotation direction of the cutting element 140 is different from the rotation direction of the housing 110, the cutting direction of the cutting element 140 can form a certain angle with the winding direction of the entanglement on the housing 110. Therefore, the cutting element 140 can cut the entanglement radially, thereby cutting off the entanglement on the housing 110, reducing the impact of the entanglement on the cleaning roller brush 100, improving the working effect of the cleaning roller brush 100, and increasing the service life of the cleaning roller brush 100.

[0046] In some embodiments, the transmission component 130 is fixedly mounted on the housing 110, meaning that the transmission component 130 and the housing 110 do not move and can be considered as a single unit. During the rotation of the housing 110, the transmission component 130 rotates along with it. The rotation of the housing 110 drives the rotation of the transmission component 130, eliminating the need for a separate drive mechanism to drive the transmission component 130, thus reducing the number of parts in the cleaning roller brush 100 and reducing its cost to some extent. Since a separate drive mechanism for the transmission component 130 is not required, there is no need to reserve an installation position on the housing 110, further reducing the overall size of the cleaning roller brush 100.

[0047] During the rotation of the housing 110, the transmission component 130 will rotate simultaneously with the housing 110. That is, when the housing 110 starts to rotate, the transmission component 130 will drive the cutting component 140 to rotate. In other words, when the cleaning part 150 on the housing 110 starts cleaning the floor, the transmission component 130 will drive the cutting component 140 to rotate, thereby cutting the tangled material. In other words, the cutting component 140 will rotate at the same time as the cleaning roller brush 100 starts cleaning. If there is tangled material wrapped around the housing 110, the cutting component 140 can cut the tangled material in time, and there will basically be no situation where there is a lot of tangled material on the housing 110, which will affect the cleaning effect.

[0048] Since the cutting element 140 rotates continuously during the rotation of the housing 110, once any entangled material is wrapped around the housing 110, the cutting element 140 will cut the entangled material. The entangled material is cut as it wraps around, meaning that the entangled material will be cut even when the quantity is small. Because the quantity of entangled material is small, the cutting element 140 will be easier to cut, which can also reduce the wear on the cutting element 140 and improve its service life.

[0049] In some embodiments, the transmission member 130 includes a transmission shaft 131 and a plurality of transmission gears 132. The transmission shaft 131 is mounted on the housing 110, and the plurality of transmission gears 132 are arranged along the extending direction of the housing 110.

[0050] Since the housing 110 is generally cylindrical, the extension direction of the housing 110 refers to the length direction of the housing 110. The rotating shaft and the transmission gear 132 are both installed inside the housing 110. The transmission shaft 131 is arranged along the extension direction of the housing 110, which allows at least one cutting element 140 to be arranged in the extension direction of the housing 110, thereby enabling the cutting of entangled material at different parts of the housing 110, ensuring that there is as little entangled material as possible on the housing 110, thereby improving the cleaning effect of entangled material.

[0051] In some embodiments, the drive shaft 131 is mounted on the housing 110. The drive shaft 131 drives multiple drive gears 132 to rotate together with the housing 110. That is, the rotation direction of the drive shaft 131 is the same as the rotation direction of the housing 110, while the rotation direction of the cutting component 140 is different from the rotation direction of the housing 110. Therefore, the cooperation between the drive gears 132 and the cutting component 140 needs to achieve the rotation direction of the cutting component 140. Therefore, the drive gears 132 can be bevel gears.

[0052] Please refer to Figures 4 and 5. In some embodiments, the drive shaft includes multiple shaft segments 131a and connecting sleeves 131b. Two adjacent shaft segments 131a are connected by connecting sleeves 131b. Each shaft segment 131a is provided with a drive gear 132.

[0053] Due to the relatively long length of the housing 110, the drive shaft 131 can be configured into multiple shaft segments 131a. Two adjacent shaft segments 131a can be connected by a coupling sleeve 131b. At least one drive gear 132 can be provided on each shaft segment 131a, thereby facilitating the fixing of the drive shaft 131.

[0054] In some embodiments, a bearing may be provided on each shaft segment 131a. For ease of description, the bearing on the shaft segment 131a is defined as the first bearing 131c. The first bearing 131c is fixedly connected to the housing 110 for mounting and fixing each shaft segment 131a, thereby providing support for the shaft segment 131a.

[0055] Multiple mounting slots 111 can be provided in the extending direction of the housing 110. Multiple first bearings 131c are respectively installed in the mounting slots 111. The first bearings 131c are fixed to the housing 110 through the mounting slots 111. The mounting slots 111 can limit and fix the first bearings 131c. In addition, other fixing structures can be provided to fix the bearings to the housing 110. In some embodiments, the coupling sleeve 131b can be fixed to the housing 110 by snap-fit ​​or by screws.

[0056] Referring to Figure 6, in some embodiments, there may be multiple cutting elements 140. The multiple cutting elements 140 are arranged sequentially at intervals along the extending direction of the housing 110.

[0057] Since the housing 110 is a long, cylindrical shape, the cutting element 140 needs to be mounted on the housing 110. Therefore, the size of the cutting element 140 is much smaller than that of the housing 110. The entangled material may be wrapped around any part of the housing 110. To clean the entangled material from any part, multiple cutting elements 140 can be provided. Multiple cutting elements 140 are arranged sequentially along the extension direction of the housing 110 to clean the entangled material from different parts of the housing 110, thereby minimizing the possibility of linear objects getting entangled on the housing 110 and affecting the operation of the cleaning roller brush 100. Since the cutting elements 140 all have relatively sharp blades, adjacent cutting elements 140 can be arranged at intervals to avoid interference between adjacent cutting elements 140.

[0058] It is easy to understand that the transmission gear 132 of the transmission component 130 is connected to the cutting component 140. Therefore, the number of transmission gears 132 should not be less than the number of cutting components 140, so that each cutting component 140 can rotate during the rotation of the housing 110, thereby cutting the entangled material.

[0059] In some embodiments, a plurality of cutting elements 140 are respectively disposed on both sides of the transmission element 130.

[0060] In some embodiments, the transmission member 130 may be disposed in the middle of the housing 110. Multiple cutting members 140 are respectively arranged on both sides of the transmission member 130, that is, the multiple cutting members 140 can be considered as being divided into two groups, with one group of cutting members 140 disposed on each side of the transmission member 130, or multiple cutting members 140 in the same group. Similarly, multiple cutting members 140 in the same group are arranged sequentially at intervals along the extending direction of the housing 110.

[0061] In some embodiments, if there are 8 cutting elements 140, then each group of cutting elements 140 located on both sides of the transmission member 130 can have 4 cutting elements 140; the 4 cutting elements 140 in the same group are arranged sequentially at intervals along the extension direction of the housing 110. If there are 7 cutting elements 140, one group of cutting elements 140 can have 4 cutting elements 140, and another group of cutting elements 140 can have 3 cutting elements 140. When the total number of cutting elements 140 is other than 140, the arrangement of the cutting elements 140 can be specifically set according to the length of the housing 110.

[0062] Multiple cutting elements 140 are respectively arranged on both sides of the transmission element 130. On the same circumference of the housing 110, one cutting element 140 or two cutting elements 140 can be arranged. That is, in the extension direction of the housing 110, the two sets of cutting elements 140 located on both sides of the transmission element 130 can be arranged alternately, symmetrically, or partially overlapping.

[0063] Since all the cutting elements 140 have blades, to avoid interference between adjacent cutting elements 140, the two cutting elements 140 on the same side need to be spaced apart. Furthermore, since the housing 110 is elongated, if all the cutting elements 140 are spaced apart, the cutting area of ​​all the cutting elements 140 cannot cover the entire housing 110, meaning there will be blind spots. By providing cutting elements 140 on both sides of the transmission element 130, interference between the two cutting elements 140 on the same side can be avoided, while also ensuring that the cutting area of ​​all the cutting elements 140 covers the entire housing 110 as much as possible, minimizing cutting blind spots, thereby improving the cleaning effect on tangled materials and ultimately improving the cleaning effect of the cleaning roller brush 100.

[0064] In some embodiments, each cutter 140 forms a cut projection on the same side of the housing 110 along its axis of rotation 141, and two adjacent cut projections partially overlap.

[0065] In some embodiments, a plurality of cutting elements 140 are arranged sequentially along the extension direction of the housing 110. The projection of the cutting element 140 on the housing 110 along its own axis of rotation 141 essentially refers to the projection of a single cutting element 140 in the extension direction of the housing 110, and also refers to the length covered by a single cutting element 140 in the extension direction of the housing 110, that is, it can be considered as the cutting range of a single cutting element 140 in the extension direction of the housing 110.

[0066] Multiple cutting elements 140 may be disposed on the same side of the transmission member 130 or on different sides of the transmission member 130. Regardless of whether the multiple cutting elements 140 are disposed on the same side or different sides of the transmission member 130, each individual cutting element 140 can cover a certain length in the extending direction of the housing 110. Projecting the multiple cutting elements 140 along their own axis of rotation 141 onto the same side of the housing 110 can visually reflect the coverage range of the multiple cutting elements 140 in the extending direction of the housing 110.

[0067] In some embodiments, the two adjacent cutting projections at least partially overlap, indicating that the cutting ranges of the two adjacent cutting elements 140 in the extending direction of the housing 110 overlap, that is, the multiple cutting elements 140 can basically completely cover the entire housing 110. This avoids cutting blind spots as much as possible, thereby improving the cleaning effect on tangled materials, and thus improving the cleaning effect of the cleaning roller brush 100.

[0068] In some embodiments, the cutting element 140 cuts the tangled material by rotating. During the rotation of the cutting element 140, the cutting force at the edge of the cutting element 140 is weaker than that in the middle. Since the cutting areas of two adjacent cutting elements 140 overlap, the edge area with slightly weaker cutting force can be cut simultaneously by two cutting elements 140, thereby improving the cleaning effect on the tangled material.

[0069] Referring to Figures 7 and 8, in some embodiments, the cutting member 140 includes a rotating shaft 141, a cutting portion 142, and a transmission portion 143. The transmission portion 143 and the cutting portion 142 are sleeved on the rotating shaft 141. The rotating shaft 141 is mounted on the housing 110. The cutting portion 142 is at least partially driven connected to the rotating shaft 141. The cutting portion 142 is driven connected to the transmission member 130.

[0070] The rotating shaft 141 is rotatably connected to the housing 110. Both the cutting part 142 and the transmission part 143 are mounted on the rotating shaft 141. The transmission part 143 is connected to the transmission gear 132, thereby enabling the rotating shaft 141 and the cutting part 142 to rotate relative to the housing 110. In some embodiments, the transmission part 143 can be a bevel gear, and the transmission gear 132 can also be a bevel gear. The meshing of the two bevel gears can change the rotation direction of the cutting part 142, making its rotation direction different from that of the housing 110, thereby enabling the cutting of the wound material.

[0071] In some embodiments, the extending direction of the rotating shaft 141 is set at an angle to the extending direction of the housing 110. That is, the cutting direction of the cutting part 142 is different from the rotation direction of the housing 110.

[0072] In some embodiments, the cutting part 142 is mainly used to cut the wrapped material. During the cutting process, the cutting part 142 can cut the wrapped material with one blade or with two blades moving in opposite directions. The following will introduce two different structures of the cutting part 142.

[0073] In some embodiments, as shown in Figures 7 and 8, the cutting section 142 includes a first cutting blade 142c and a second cutting blade 142a. The second cutting blade 142a is fixedly connected to the housing 110. The first cutting blade 142c is drive-connected to the rotating shaft 141.

[0074] Both the first cutting blade 142c and the second cutting blade 142a are sleeved on the rotating shaft 141. However, only the first cutting blade 142c rotates with the rotating shaft 141. The second cutting blade 142a is fixed on the housing 110. The transmission member 130, through the meshing of the transmission gear 132 and the transmission part 143, enables the rotating shaft 141 to drive the first cutting blade 142c to rotate, that is, the first cutting blade 142c and the second cutting blade 142a rotate relative to each other, thereby cutting the entanglement between the first cutting blade 142c and the second cutting blade 142a.

[0075] The first cutting blade 142c and the second cutting blade 142a move towards each other. Their cutting principle is the same as that of scissors, which causes the wrapped material to be subjected to force from two different directions, thereby increasing the force applied to the wrapped material. This allows the wrapped material to be cut off quickly, thus improving the cutting effect.

[0076] In some embodiments, the second cutting blade 142a may be provided with a plurality of second cutting edges 142b. The plurality of second cutting edges 142b are arranged at intervals along the circumference of the second cutting blade 142a. The first cutting blade 142c is provided with a plurality of first cutting edges 142d. The first cutting edges 142d are arranged at intervals along the circumference of the first cutting blade 142c. The second cutting edges 142b and the first cutting edges 142d are arranged facing each other.

[0077] When the first cutting blade 142c and the second cutting blade 142a are working together, as the first cutting blade 142c rotates with the rotating shaft 141, since the first cutting blade 142c is provided with multiple first cutting blades 142d and the second cutting blade 142a is provided with multiple second cutting blades 142b, the first cutting blade 142c can perform multiple cuts on the entangled material by cooperating with multiple second cutting blades 142b and multiple first cutting blades 142d for each rotation, thereby improving the cutting efficiency.

[0078] Because the first cutting blade 142c and the second cutting blade 142a apply force to the winding material from two different directions, the first cutting blade 142d and the second cutting blade 142b can cut the winding material with relatively small forces during the cutting process. In other words, the reaction force from the winding material on the first cutting blade 142d and the second cutting blade 142b is relatively small. Therefore, the strength requirement for the first cutting blade 142c is lower than that for a single cutting blade, and the first cutting blade 142c can be made into a disc shape with a small thickness. The first cutting blade 142c may include a blade portion 142e and a first body 142f. The blade portion 142e protrudes from the first body 142f. The first cutting blade 142d is disposed on the side wall of the blade portion 142e.

[0079] Since the same cutting edge 142e includes left and right sides, the first cutting edge 142d can be provided on both sides of each cutting edge 142e, or the first cutting edge 142d can be provided on only one side of the cutting edge 142e. When the first cutting edge 142d is provided on only one side of the cutting edge 142e, the first cutting edge 142d of multiple cutting edge 142es can be provided in the same way, that is, they can all be provided on the left side of the cutting edge 142e, or they can all be provided on the right side of the cutting edge 142e.

[0080] The first cutting edge 142d is disposed on one side of the blade portion 142e. Since the reaction force of the wrapped material on the first cutting edge 142d is small, the force on a single blade portion 142e is also small. Therefore, the strength requirement for a single blade portion 142e is not high. The width of a single blade portion 142e can be set to be small, and the length protruding from the first body 142f can be set to be short.

[0081] Similarly, the strength requirement for the second cutting blade 142a is lower than that for the case of only one cutting blade. The second cutting blade 142a can also be set as a disc with a smaller thickness, and the length of the second cutting blade 142b can also be set to be smaller.

[0082] Referring to Figures 9 and 10, in some embodiments, the second cutting blade 142a is disposed between the transmission member and the first cutting blade 142c. The cutting member 140 may also include a second bearing 144 and an elastic member 145. The second bearing 144 is sleeved on the rotating shaft 141 and is located between the first cutting blade 142c and the housing 110. The elastic member 145 is disposed between the housing 110 and the second bearing 144. The two ends of the elastic member 145 abut against the housing 110 and the second bearing 144, respectively, and can provide a restoring force to the first cutting blade 142c through the second bearing 144 to maintain contact with the second cutting blade 142a, so that there is always a certain pressure between the second cutting blade 142a and the first cutting blade 142c, and can maintain contact during the relative movement of the second cutting edge 142b and the first cutting edge 142d, thereby increasing the force applied to the wound material and enabling rapid cutting of the wound material. Please refer to Figures 11 and 12. The foregoing detailed the case where the cutting unit 142 has two cutting blades. However, in other embodiments, the cutting unit 142 may only have one cutting blade, i.e., the cutting unit 142 includes only the first cutting blade 142c'. The wound material is cut solely by the moving first cutting blade 142c'. When the cutting unit 142 only has the first cutting blade 142c', the first cutting blade 142c' has the same installation position and movement method as the first cutting blade 142c in the case where both the second cutting blade 142a and the first cutting blade 142c are provided. The description of other structures in this disclosure will not separately list the arrangement position of the cutting unit 142 when only the first cutting blade 142c' is provided. The installation position and movement method of the first cutting blade 142c' are the same as the installation position and movement method of the first cutting blade 142c in the case where both the first cutting blade 142c and the second cutting blade 142a are provided; other configurations can be deduced similarly.

[0083] The difference between the cutting section 142 including only the first cutting blade 142c' and the cutting section 142 including both the first cutting blade 142c and the second cutting blade 142a, lies in the different lengths, widths, and thicknesses of the blade portion 142e' and the different diameters of the first body 142f'. In the first case, i.e., when the cutting section 142 includes only the first cutting blade 142c', the winding material is subjected to force in only one direction when the first cutting blade 142c' cuts the winding material. In this case, the force required to cut the same winding material by the first cutting blade 142c' is greater than that required by the case of two cutting blades, thus requiring greater strength from the first cutting blade 142c'. Therefore, the width, thickness, and length of the blade portion 142e' can be set to be larger, thereby improving the strength of the first cutting blade 142c'. In the second case, where the cutting section 142 includes a first cutting blade 142c and a second cutting blade 142a, the outer diameters of the first cutting blades 142c and 142c' need to be the same in order to fit the same housing 110. Therefore, in the case where the cutting section 142 only includes the first cutting blade 142c', the diameter of the first body 142f' is set to be smaller.

[0084] Referring to Figures 13 and 14, in some embodiments, the housing 110 has a receiving cavity 112 and a plurality of cutting grooves 113 communicating with the receiving cavity 112. The transmission member 130 and the cutting member 140 are disposed within the receiving cavity 112. The plurality of cutting members 140 are respectively disposed corresponding to the plurality of cutting grooves 113, and the second cutting blade 142b is at least partially offset from the cutting grooves 113.

[0085] The entire cutting assembly 120 is disposed inside the receiving cavity 112. The second cutting blade 142a and the first cutting blade 142c can extend out of the receiving cavity 112 through the cutting groove 113, thereby cutting the wrapped material wrapped around the outer circumference of the housing 110. At least a portion of the second cutting blade 142b is misaligned with the cutting groove 113, so that the wrapped material can be inserted into the cutting groove 113, and then into the space between the second cutting blade 142b and the first cutting blade 142d, so that the first cutting blade 142c can cooperate with the second cutting blade 142a during rotation to cut the wrapped material.

[0086] Multiple fixing grooves 114 can be provided in the receiving cavity 112. Multiple cutting parts 140 are respectively set in multiple fixing grooves 114, that is, the second bearing 144 can be fixed in the fixing groove 114.

[0087] In some embodiments, the cutting component 120 is mounted on the housing 110 and can rotate synchronously with the housing 110 during rotation, thereby cutting the wrapped material wrapped around the outer peripheral surface of the housing 110. The specific structure and cutting method of the cutting component 120 have been described in detail above. The following will describe in detail how the cutting component 120 is installed and arranged on the housing 110.

[0088] In some embodiments, the housing 110 includes a receiving cavity 112 and a cutting groove 113 communicating with the receiving cavity 112. The cutting assembly 120 is installed in the receiving cavity 112, and the cutting portion 142 of the cutting member 140 is at least partially exposed in the cutting groove 113.

[0089] The cleaning unit 150 is disposed outside the housing 110, that is, outside the receiving cavity 112. The cutting assembly 120 is installed outside the receiving cavity 112, so that the housing 110 can provide a certain degree of protection for the cutting assembly 120 and minimize the damage to the cutting assembly 120 caused by external structures.

[0090] Installing the cutting component 120 inside the receiving cavity 112 eliminates the need to occupy space outside the housing 110, making the structure of the entire cleaning roller brush 100 more compact without increasing the diameter of the cleaning roller brush 100.

[0091] In some embodiments, at least a portion of the cutting portion 142 of the cutting member 140 being exposed outside the cutting groove 113 means that at least a portion of the second cutting edge 142b and the first cutting edge 142d can be exposed outside the cutting groove 113. This can be either the entire second cutting edge 142b and the first cutting edge 142d extending out of the receiving cavity 112 from the cutting groove 113, or only a portion extending out of the receiving cavity 112 from the cutting groove 113. Since the winding material is wrapped around the outer peripheral surface of the housing 110, the second cutting edge 142b and the first cutting edge 142d extend from the cutting groove 113 to the outside of the receiving cavity 112. This facilitates cutting the winding material on the outer peripheral surface and enables effective cutting of the winding material.

[0092] In some embodiments, the cutting groove 113 is provided with a plurality of spaced sub-grooves 113a. Along the extending direction of the housing 110, some sub-grooves 113a of two adjacent cutting grooves 113 are connected.

[0093] The same cutting groove 113 is provided with multiple spaced sub-grooves 113a, which can be considered as dividing the same cutting groove 113 into multiple spaced sub-grooves 113a. The width of each sub-groove 113a is smaller than the width of the cutting groove 113, that is, the width of a single sub-groove 113a is relatively small, which can prevent larger external impurities from entering the receiving cavity 112 to a certain extent, so as to play a certain protective role.

[0094] In the extending direction of the housing 110 (i.e., in the length direction of the housing 110), the cutting portion 142 of each cutting element 140 is installed in the corresponding cutting groove 113 and cuts the area corresponding to the cutting groove 113. If some sub-grooves 113a of two adjacent cutting grooves 113 are connected, it means that the cutting areas of two adjacent cutting elements 140 partially overlap, that is, multiple cutting elements 140 can basically completely cover the entire housing 110, so as to avoid cutting blind spots as much as possible, thereby improving the cleaning effect of entangled objects, and thus improving the cleaning effect of the cleaning roller brush 100.

[0095] Since the second cutting blade 142a is provided with multiple second cutting edges 142b, and the second cutting blade 142a is fixed inside the receiving cavity 112, the gap between two adjacent second cutting edges 142b can be set to correspond to the sub-groove 113a. That is, the multiple second cutting edges 142b and the multiple sub-groove 113a are staggered, so that the wrapped material can fall into the space between two adjacent second cutting edges 142b through the sub-groove 113a. Therefore, during cutting, the force applied to the wrapped material can be increased by making the lower part of the second cutting edge 142b and the first cutting edge 142d cut the wrapped material as much as possible, thereby improving the cutting effect.

[0096] Please refer to Figures 14 and 15. In some embodiments, the housing 110 is provided with a mounting portion 115. A cutting groove 113 is provided on the mounting portion 115. Since the winding material is wound around the outer surface of the housing 110, and the cutting groove 113 is provided on the mounting portion 115 protruding from the housing 110, the cutting portion 142 (the second cutting blade 142b and the first cutting blade 142d) can extend out of the outer surface of the housing 110, that is, the cutting portion 142 (the second cutting blade 142b and the first cutting blade 142d) can protrude from the outer surface of the housing 110, that is, it can protrude from the winding position of the winding material, so that the cutting portion 142 (the second cutting blade 142b and the first cutting blade 142d) can cut the winding material.

[0097] The mounting portion 115 is mainly used to accommodate the cutting portion 142. The shape of the mounting portion 115 can be adapted to the shape of the cutting portion 142. Since the cutting portion 142 is approximately circular, the mounting portion 115 can be provided in an arc shape. Thus, the mounting portion 115 can minimize its external dimensions while accommodating the cutting portion 142.

[0098] In some embodiments, the height of the mounting portion 115 protruding from the housing 110 is less than the height of the cleaning portion 150 protruding from the housing 110. The cleaning portion 150 is mainly used for cleaning the floor. If the height of the mounting portion 115 protruding from the housing 110 is greater than the height of the cleaning portion 150 protruding from the housing 110, the mounting portion 115 will contact the floor during the rotation of the housing 110, preventing the cleaning portion 150 from contacting the floor and thus preventing it from cleaning.

[0099] The height of the mounting part 115 protruding from the housing 110 is less than the height of the cleaning part 150 protruding from the housing 110, which can avoid interference with the ground during the cleaning part 150's cleaning process, thus preventing the cleaning part 150 from cleaning the ground normally.

[0100] In some embodiments, the same cutting element 140 corresponds to two mounting portions 115. The two mounting portions 115 corresponding to the same cutting element 140 can be respectively disposed on opposite sides of the housing 110. The cleaning portion 150 is disposed between the two mounting portions 115 corresponding to the same cutting element 140.

[0101] Since the cutting portion 142 of the cutting member 140 is circular, the same cutting portion 142 corresponds to two mounting portions 115, and the two mounting portions 115 are respectively provided on opposite sides. That is, the same turn of the winding material can be cut through the cutting grooves 113 on the two mounting portions 115 by the same cutting portion 142. The same cutting portion 142 can cut the same turn of the winding material twice, cutting the winding material into a smaller length, which can reduce the risk of the winding material re-winding onto the housing 110.

[0102] The cleaning part 150 is disposed between two mounting parts 115 corresponding to the same cutting member 140. The cleaning part 150 can be arranged by utilizing the gap between the two mounting parts 115 of the same cutting member 140, making the structure of the entire cleaning roller brush 100 more compact.

[0103] In some embodiments, the housing 110 may include a detachably connected upper housing 116 and lower housing 117. If it is necessary to repair the internal cutting assembly 120, the upper housing 116 and lower housing 117 can be separated to expose the cutting assembly 120 for repair or replacement.

[0104] In summary, a cleaning roller brush 100 is provided according to the embodiments disclosed herein. During the rotation of the housing 110, linear entanglements such as hair will wrap around the housing 110 in the direction of rotation. The rotation direction of the cutting member 140 is different from that of the housing 110, so that the cutting direction of the cutting member 140 can have a certain angle with the winding direction of the entanglement on the housing 110. The cutting member 140 can cut the entanglement radially, thereby cutting off the entanglement on the housing 110, reducing the impact of the entanglement on the cleaning roller brush 100, improving the working effect of the cleaning roller brush 100, and increasing the service life of the cleaning roller brush 100.

[0105] This embodiment also provides a cleaning device 1, which includes a main body 10 and the aforementioned cleaning roller brush 100, the cleaning roller brush 100 being mounted on the main body 10. The main body 10 is the main structure of the entire cleaning device 1. In some embodiments, the cleaning device 1 may be a robotic vacuum cleaner, a floor scrubber, a vacuum cleaner, etc.

[0106] Please refer to Figures 15 and 16. The cleaning device also includes a drive mechanism. The cleaning roller brush also includes a fixed part 160 and a moving part 170. The fixed part 160 and the moving part 170 are respectively disposed at opposite ends of the housing 110. The fixed part 160 is connected to the drive mechanism for transmission, and the moving part 170 is rotatably connected to the main body 10.

[0107] In some embodiments, the movable part 170 includes a spindle 172 and a bearing sleeve 174. The spindle 172 is fixedly connected to the main body 10, and the bearing sleeve 174 is disposed between the spindle 172 and the housing 110, so that the housing 110 can rotate relative to the main body 10.

[0108] This disclosure embodiment also provides a cleaning system. The cleaning system includes a cleaning base station 2 and the cleaning device 1 described above. The cleaning base station 2 may have functions such as charging the cleaning device 1, cleaning the cleaning device 1, and collecting impurities from the cleaning device 1. In some embodiments, the cleaning device 1 may be detachably disposed on the cleaning base station 2.
