[0054] With the development of science and technology, cleaning equipment has become more and more popular. Most cleaning equipment uses a cleaning roller brush to achieve the cleaning function of the ground. During the cleaning process, hair-like linear objects on the ground are easily entangled on the outer circumference of the cleaning roller brush. If there are many entangled objects, it will affect the cleaning function at the least, and cause the cleaning roller brush to be blocked and damage the machine at the worst. Therefore, the embodiment of the present application provides a cleaning roller brush, a cleaning device and a cleaning system. The cleaning roller brush, the cleaning device and the cleaning system provided by the embodiment of the present application can automatically clean the entangled objects entangled on the cleaning roller brush during the cleaning process, reduce the impact of the entangled objects on the cleaning roller brush, improve the working effect of the cleaning roller brush, and increase the service life of the cleaning roller brush.

[0055] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0056] See also Figure 1 The embodiment of the present application provides a cleaning roller brush 100, which is installed on a cleaning device and is mainly used to clean objects to be cleaned. The cleaning roller brush 100 provided in the embodiment of the present application can automatically clean the entangled objects wrapped around the cleaning roller brush 100 during the cleaning process, reduce the influence of the entangled objects on the cleaning roller brush 100, improve the working effect of the cleaning roller brush 100, and increase the service life of the cleaning roller brush 100.

[0057] See also Figure 1 and Figure 2 In an embodiment of the present application, the cleaning roller brush 100 includes: a shell 110, a cutting assembly 120, and a cleaning portion 150 installed on the shell 110. The cutting assembly 120 is connected to the shell 110 and can rotate relative to the shell 110. The cutting direction of the cutting assembly 120 is set at an angle to the rotation direction of the shell 110.

[0058] The housing 110 is the main body of the entire cleaning roller brush 100, and provides a mounting base for structures such as the cleaning unit 150 and the cutting assembly 120. The housing 110 is generally cylindrical and can be connected to a driving mechanism of the cleaning device. The cleaning unit 150 can rotate relative to the main body of the cleaning device under the drive of the driving mechanism. The cleaning unit 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 unit to clean the ground.

[0059] Among them, the cleaning part 150 can be in the shape of a long strip, and the cleaning part 150 can be arranged along the extension direction of the shell 110. Specifically, the cleaning part 150 can be arranged in a straight line in the extension direction of the shell 110, or in an arc shape in the extension direction of the shell 110, or can be arranged in a spiral shape in the extension direction of the brush. The specific method is not limited.

[0060] There may be a plurality of cleaning parts 150 , and the plurality of cleaning parts 150 are arranged at intervals on the circumference of the housing 110 . The shapes of any two cleaning parts 150 may be the same or different.

[0061] When the cleaning device drives the cleaning roller brush 100 to rotate, the hair and other linear winding objects will be wound around the outer peripheral surface of the shell 110 as the shell 110 rotates, that is, the winding direction of the winding objects is the same as the rotation direction of the shell 110. Figure 1 and Figure 2 ) and the rotation direction of the housing 110 ( Figure 1 and Figure 2 The X direction shown in the figure is set at an angle, indicating that the cutting direction of the cutting assembly 120 is different from the rotation direction of the shell 110. Since the winding direction of the winding is the same as the rotation direction of the shell 110, it can be known that the cutting direction of the cutting assembly 120 is different from the winding direction of the winding, that is, the cutting direction of the cutting assembly 120 is different from the length direction of the linear winding. The cutting direction of the cutting assembly 120 is different from the length direction of the winding. During the rotation of the cutting assembly 120 relative to the shell 110, the cutting direction of the cutting assembly 120 at least has a component along the radial direction of the winding, so that the cutting assembly 120 can cut off the winding, avoid the winding of the winding on the shell 110 as much as possible, reduce the influence of the winding on the cleaning roller brush 100, improve the working effect of the cleaning roller brush 100, and improve the service life of the cleaning roller brush 100.

[0062] See also Figure 3 In some embodiments, the cutting assembly 120 includes a transmission member 130 and a cutting member 140 transmission-connected to the transmission member 130 , the transmission member 130 is fixedly connected to the housing 110 , and the cutting member 140 is rotationally connected to the housing 110 .

[0063] The transmission member 130 is fixed on the housing 110 and is in transmission connection with the cutting member 140. When the driving mechanism of the cleaning device drives the housing 110 to rotate, the transmission member 130 rotates along with the housing 110, so that the transmission member 130 can drive the cutting member 140 to rotate relative to the housing 110. The transmission member 130 mainly drives the cutting member 140 to rotate relative to the housing, and the cutting member 140 is mainly used to cut windings.

[0064] 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 .

[0065] The cutting direction of the cutting piece 140 can be considered as the rotation direction of the cutting piece 140 relative to the shell 110. The cutting direction of the cutting piece 140 is set at an angle to the rotation direction of the shell 110, that is, the rotation direction of the cutting piece 140 is different from the rotation direction of the shell 110. During the rotation of the shell 110, linear windings such as hair will be wound around the shell 110 along the rotation direction of the shell 110, and the rotation direction of the cutting piece 140 is different from the rotation direction of the shell 110, so that the cutting direction of the cutting piece 140 can have a certain angle with the winding direction of the winding on the shell 110, and the winding can be cut in the radial direction of the winding, so that the winding on the shell 110 can be cut off, thereby reducing the influence of the winding on the cleaning roller brush 100, improving the working effect of the cleaning roller brush 100, and improving the service life of the cleaning roller brush 100.

[0066] The transmission member 130 is fixedly mounted on the housing 110. The transmission member 130 and the housing 110 will not move. It can be considered that the transmission member 130 and the housing 110 are a whole. During the rotation of the housing 110, the transmission member 130 will rotate along with the housing 110. The rotation of the housing 110 can drive the rotation of the transmission member 130, and there is no need to set up another driving mechanism to drive the transmission member 130 to rotate separately, which reduces the number of parts of the cleaning roller brush 100 and can reduce the cost of the cleaning roller brush 100 to a certain extent. At the same time, since there is no need to set up a driving mechanism for the transmission member 130 separately, there is no need to reserve an installation position on the housing 110, which can also reduce the volume of the entire cleaning roller brush 100.

[0067] During the rotation of the housing 110, the transmission member 130 will rotate simultaneously with the housing 110, that is, when the housing 110 starts to rotate, the transmission member 130 will drive the cutting member 140 to rotate, that is, when the cleaning part 150 on the housing 110 starts to clean the floor, the transmission member 130 will drive the cutting member 140 to rotate, and then cut the entangled objects. In other words, when the cleaning roller brush 100 starts to clean, the cutting member 140 will rotate, and if there are entangled objects wrapped around the housing 110, the cutting member 140 can cut the entangled objects in time, and there will basically be no situation where there are too many entangled objects on the housing 110 and affect the cleaning effect.

[0068] In addition, since the cutting piece 140 will continue to rotate during the rotation of the shell 110, if there is a winding material wrapped around the shell 110, the cutting piece 140 will cut the winding material, and the winding material will be cut as it is wrapped, that is, the winding material will be cut when the number is small. Since the number of winding materials is small, it will be easier for the cutting piece 140 to cut, and the wear on the cutting piece 140 can also be reduced, thereby increasing the service life of the cutting piece 140.

[0069] 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 an extension direction of the housing 110 .

[0070] Since the shell 110 is roughly cylindrical, the extension direction of the shell 110 refers to the length direction of the shell 110, the rotating shaft and the transmission gear 132 are both installed inside the shell 110, and the transmission shaft 131 is arranged along the extension direction of the shell 110, so that at least one cutting member 140 can be arranged in the extension direction of the shell 110, so that the entanglements in different parts of the shell 110 can be cut, and it is ensured as much as possible that there are no entanglements on the shell 110, thereby improving the cleaning effect of the entanglements.

[0071] Among them, the transmission shaft 131 is installed on the shell 110, and the transmission shaft 131 will drive multiple transmission gears 132 to rotate along with the shell 110, that is, the rotation direction of the transmission shaft 131 is the same as the rotation direction of the shell 110, and the rotation direction of the cutting piece 140 is different from the rotation direction of the shell 110. Then, the cooperation between the transmission gear 132 and the cutting piece 140 needs to realize the steering of the cutting piece 140. Therefore, the transmission gear 132 can use a bevel gear.

[0072] See also Figure 4 and Figure 5 In some embodiments, the transmission shaft 131 includes a plurality of shaft segments 131 a and a coupling sleeve 131 b , two adjacent shaft segments 131 a are connected via the coupling sleeve 131 b , and each shaft segment 131 a is provided with a transmission gear 132 .

[0073] Since the shell 110 is relatively long, the transmission shaft 131 can be configured into multiple shaft segments 131a. Two adjacent shaft segments 131a can be connected via a shaft sleeve 131b. At least one transmission gear 132 can be provided on each shaft segment 131a, thereby facilitating the fixation of the transmission shaft 131.

[0074] Specifically, a bearing can be set on each shaft segment 131a. For the convenience of description, the bearing on the shaft segment 131a is defined as a first bearing 131c. The first bearing 131c is fixedly connected to the housing 110 and is mainly used to install and fix each shaft segment 131a, and can support the shaft segment 131a.

[0075] In the extension direction of the housing 110, a plurality of mounting grooves 111 may be provided, and a plurality of first bearings 131c may be respectively installed in the mounting grooves 111, and the first bearings 131c may be fixed to the housing 110 through the mounting grooves 111. The mounting grooves 111 may limit and fix the first bearings 131c, and in addition, other fixing structures may be provided to fix the bearings to the housing 110. For example, the coupling sleeve 131b may be fixed to the housing 110 by means of a clamping connection or by screws.

[0076] See also Figure 6 In some embodiments, there may be a plurality of cutting members 140 , and the plurality of cutting members 140 are arranged in sequence and spaced apart along the extension direction of the housing 110 .

[0077] Since the housing 110 is a long cylindrical body, the cutting piece 140 needs to be installed on the housing 110, so the size of the cutting piece 140 is much smaller than that of the housing 110, and the winding object may be wound around any part of the housing 110. In order to be able to clean the winding object at any part, multiple cutting pieces 140 can be provided, and the multiple cutting pieces 140 are arranged in sequence along the extension direction of the housing 110, which can clean the winding objects at different parts of the housing 110 and avoid the winding of the linear objects around the housing 110 as much as possible, which affects the work of the cleaning roller brush 100. Since the cutting pieces 140 have relatively sharp blades, in order to avoid interference between two adjacent cutting pieces 140, the two adjacent cutting pieces 140 can be arranged at intervals.

[0078] It is easy to understand that the transmission gear 132 of the transmission member 130 is transmission-connected with the cutting member 140 , and the number of the transmission gear 132 should be not less than the number of the cutting member 140 , so that each cutting member 140 can also rotate during the rotation of the shell 110 , thereby cutting the winding material.

[0079] In some embodiments, the plurality of cutting members 140 are respectively disposed on both sides of the transmission member 130 .

[0080] Among them, the transmission member 130 can be set in the middle of the shell 110, and the multiple cutting members 140 are respectively arranged on both sides of the transmission member 130, that is, the multiple cutting members 140 can be regarded as divided into two groups, and a group of cutting members 140 is respectively set on both sides of the transmission member 130, and the same group can also be multiple cutting members 140; similarly, the multiple cutting members 140 in the same group are arranged in sequence along the extension direction of the shell 110.

[0081] For example, if there are 8 cutting members 140, each group of cutting members 140 located on both sides of the transmission member 130 may be 4, and the 4 cutting members 140 in the same group are sequentially arranged at intervals along the extension direction of the housing 110. If there are 7 cutting members 140, one group may be 4 cutting members 140 and the other group may be 3. When the total number of the cutting members 140 is other numbers, the arrangement of the cutting members 140 may be specifically set according to the length of the housing 110.

[0082] Multiple cutting members 140 are respectively arranged on both sides of the transmission member 130. On the same circumference of the shell 110, one cutting member 140 or two cutting members 140 can be arranged, that is, in the extension direction of the shell 110, the two groups of cutting members 140 located on both sides of the transmission member 130 can be arranged alternately, symmetrically, or partially overlapping.

[0083] Since the cutting members 140 all have blades, in order to avoid interference between two adjacent cutting members 140, the two cutting members 140 on the same side need to be arranged at intervals. Since the housing 110 is in the shape of a long strip, if all the cutting members 140 are arranged at intervals, the cutting areas of all the cutting members 140 cannot cover the entire housing 110, that is, there will be blind spots for the cutting members 140. The cutting members 140 are arranged on both sides of the transmission member 130, which can avoid interference between the two cutting members 140 on the same side, and can make the cutting areas of all the cutting members 140 cover the entire housing 110 as much as possible, avoiding the occurrence of blind cutting areas as much as possible, thereby improving the cleaning effect of the entangled objects, and further improving the cleaning effect of the cleaning roller brush 100.

[0084] In some embodiments, each cutting member 140 forms a cutting projection on the same side of the housing 110 along the direction of its rotation axis 141 , and two adjacent cutting projections partially overlap.

[0085] Among them, multiple cutting pieces 140 are arranged in sequence along the extension direction of the shell 110, and the projection of the cutting piece 140 along the direction of its own rotating axis 141 on the shell 110 actually refers to the projection of a single cutting piece 140 in the extension direction of the shell 110, and also refers to the coverage length of a single cutting piece 140 in the extension direction of the shell 110, that is, it can be considered as the cutting range of a single cutting piece 140 in the extension direction of the shell 110.

[0086] Since the multiple cutting members 140 may be arranged on the same side of the transmission member 130 or on different sides of the transmission member 130, no matter the multiple cutting members 140 are arranged on the same side of the transmission member 130 or on different sides, a single cutting member 140 can cover a certain length in the extension direction of the housing 110. Projecting the multiple cutting members 140 along their own rotation axes 141 onto the same side of the housing 110 can intuitively reflect the coverage of the multiple cutting members 140 in the extension direction of the housing 110.

[0087] Preferably, two adjacent cutting projections at least partially overlap, indicating that the cutting ranges of two adjacent cutting pieces 140 in the extension direction of the shell 110 have overlapping parts, that is, multiple cutting pieces 140 can basically completely cover the entire shell 110, avoiding the occurrence of cutting blind spots as much as possible, thereby improving the cleaning effect of the entangled objects, and further improving the cleaning effect of the cleaning roller brush 100.

[0088] In addition, the cutting piece 140 cuts the entangled material by rotating. During the rotation process, the cutting force at the edge of the cutting piece 140 is weakened compared to the cutting force at the middle part. Since the cutting areas of two adjacent cutting pieces 140 overlap, the edge area with weaker cutting force can be cut by two cutting pieces 140 at the same time, thereby improving the cleaning effect of the entangled material.

[0089] See also Figure 7 and Figure 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 installed on the housing 110. The cutting portion 142 is at least partially transmission-connected to the rotating shaft 141. The cutting portion 142 is transmission-connected to the transmission member 130.

[0090] The rotating shaft 141 is rotationally connected to the shell 110, and the cutting part 142 and the transmission part 143 are both installed on the rotating shaft 141. The transmission part 143 is transmission-connected to the transmission gear 132, thereby being able to drive the rotating shaft 141 and the cutting part 142 to rotate relative to the shell 110, wherein the transmission part 143 is a bevel gear, and the transmission gear 132 is also a bevel gear. The engagement of the two bevel gears can change the rotation direction of the cutting part 142, so that the rotation direction of the cutting part 142 is different from the rotation direction of the shell 110, thereby being able to cut the winding material.

[0091] In some embodiments, the extension direction of the rotating shaft 141 is arranged at an angle to the extension direction of the housing 110 , that is, the cutting direction of the cutting portion 142 is different from the rotation direction of the housing 110 .

[0092] The cutting part 142 is mainly used for cutting windings. During the cutting process, the cutting part 142 can cut with one blade or two relatively moving blades. The two different structures of the cutting part 142 will be specifically introduced below.

[0093] In some embodiments, Figure 7-8 As shown, the cutting portion 142 includes a first cutting blade 142 c and a second cutting blade 142 a . The second cutting blade 142 a is fixedly connected to the housing 110 , and the first cutting blade 142 c is drivingly connected to the rotating shaft 141 .

[0094] The first cutting knife 142c and the second cutting knife 142a are both mounted on the rotating shaft 141, but only the first cutting knife 142c will rotate with the rotating shaft 141, and the second cutting knife 142a is fixed on the shell 110. The transmission member 130 enables the rotating shaft 141 to drive the first cutting knife 142c to rotate through the engagement of the transmission gear 132 and the transmission part 143, that is, the first cutting knife 142c and the second cutting knife 142a generate relative rotation, so that the entanglement between the first cutting knife 142c and the second cutting knife 142a can be cut.

[0095] The first cutting knife 142c and the second cutting knife 142a move towards each other, and the cutting principle of the two is the same as the working principle of scissors, so that the entangled object is subjected to force from two different directions, which can increase the force applied to the entangled object, so that the entangled object can be cut off quickly, thereby improving the cutting effect of the entangled object.

[0096] In some embodiments, the second cutting knife 142a has multiple second cutting edges 142b, which are arranged at intervals along the circumference of the second cutting knife 142a, and the first cutting knife 142c has multiple first cutting edges 142d, which are arranged at intervals along the circumference of the first cutting knife 142c, and the second cutting edges 142b and the first cutting edges 142d are arranged facing each other.

[0097] When the first cutting knife 142c and the second cutting knife 142a cooperate with each other, during the process of the first cutting knife 142c following the rotation of the rotating shaft 141, since the first cutting knife 142c has multiple first cutting blades 142d and the second cutting knife 142a has multiple second cutting blades 142b, the first cutting knife 142c can achieve multiple cutting of the winding material through the cooperation of multiple second cutting blades 142b and multiple first cutting blades 142d every time it rotates one circle, thereby improving the cutting efficiency.

[0098] Since the first cutting blade 142c and the second cutting blade 142a apply forces to the winding from two different directions of the winding, the first cutting blade 142d and the second cutting blade 142b can cut the winding by applying smaller forces respectively during the process of cutting the winding. In other words, the first cutting blade 142d and the second cutting blade 142b are respectively subjected to smaller reaction forces of the winding. Therefore, the strength requirement for the first cutting blade 142c is lower than that in the case of only one cutting blade, and the first cutting blade 142c can be set in a disc shape with a smaller thickness. The first cutting blade 142c can include a blade portion 142e and a first body 142f, the blade portion 142e is convexly arranged on the first body 142f, and the first cutting blade 142d is arranged on the side wall of the blade portion 142e.

[0099] Since the same blade portion 142e has left and right sides, the first cutting edges 142d may be provided on both sides of each blade portion 142e, or the first cutting edge 142d may be provided on one side of the blade portion 142e. In the case where the first cutting edge 142d is provided on only one side of the blade portion 142e, the first cutting edges 142d of the plurality of blade portions 142e may be provided in the same manner, i.e., they may all be provided on the left side of the blade portion 142e, or they may all be provided on the right side of the blade portion 142e.

[0100] The first cutting edge 142d is arranged on one side of the blade portion 142e. Since the reaction force of the winding object on the first cutting edge 142d is small, the force on the single blade portion 142e is also small. Therefore, the strength requirement for the single blade portion 142e is not high, the width of the single blade portion 142e can be set smaller, and the length protruding from the first body 142f can be set shorter.

[0101] Similarly, the strength requirement for the second cutting blade 142a is lower than that for a case where there is only one cutting blade. The second cutting blade 142a can also be configured to be a disc with a smaller thickness, and the length of the second cutting edge 142b can also be configured to be smaller.

[0102] See also Fig. 9 and Fig.10In some embodiments, the second cutting blade 142a is disposed between the transmission member 130 and the first cutting blade 142c, and the cutting member 140 further includes a second bearing 144 and an elastic member 145. The second bearing 144 is sleeved on the rotating shaft 141 and between the first cutting blade 142c and the housing 110, and the elastic member 145 is disposed between the housing 110 and the second bearing 144. The two ends of the elastic member 145 are respectively in contact with the housing 110 and the second bearing 144, and the second bearing 144 can provide a restoring force to the first cutting blade 142c to contact 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 the second cutting blade 142b and the first cutting blade 142d can always maintain contact during the relative movement, thereby increasing the force applied to the winding object and quickly cutting the winding object. Please refer to Fig.11 and Fig.12 The above detailed description of the case where the cutting portion 142 has two cutting knives. Of course, in addition to this, in other embodiments, the cutting portion 142 may be provided with only one cutting knife, that is, the cutting portion 142 only includes the first cutting knife 142c', and the winding material is cut only by the moving first cutting knife 142c'. When the cutting portion 142' is provided with only the first cutting knife 142c', the installation position and movement method of the first cutting knife 142c in the second cutting knife 142a and the first cutting knife 142c are the same as those of simultaneously providing the second cutting knife 142a and the first cutting knife 142c. The description of other structures in the present application no longer separately lists the arrangement position when the cutting portion 142 is provided with only the first cutting knife 142c', and the installation position and movement method of the first cutting knife 142c in the second cutting knife 142a can be the same as those of simultaneously providing the first cutting knife 142c and the second cutting knife 142a, and so on.

[0103] The difference between the cutting part 142 including only the first cutting knife 142c' and the cutting part 142 including both the first cutting knife 142c and the second cutting knife 142a is that the length, width and thickness of the blade part 142e' are different and the diameter of the first body 142f' is different. In the case where the cutting part 142 includes only the first cutting knife 142c', when the first cutting knife 142c' cuts the winding, the winding is subjected to force in only one direction. Compared with the case where there are two cutting knives, the first cutting knife 142c' needs to apply a greater force to cut the same winding, so the strength requirement for the first cutting knife 142c' is relatively large. Therefore, the width of the blade part 142e' can be set larger, the thickness can also be set larger, and the length can be set longer, so as to improve the strength of the first cutting knife 142c'. In both cases, in order to fit the same housing 110 , the outer diameters of the first cutting blades 142c ( 142c ′) in both cases need to be set to be the same, so the diameter of the first body 142f ′ in the cutting portion 142 including only the first cutting blade 142c ′ is set to be smaller.

[0104] See also Fig.13 and Fig.14 In some embodiments, the shell 110 has a accommodating cavity 112 and a plurality of cutting grooves 113 connected to the accommodating cavity 112, the transmission member 130 and the cutting member 140 are arranged in the accommodating cavity 112, the plurality of cutting members 140 are respectively arranged corresponding to the plurality of cutting grooves 113, and the second cutting edge 142b is at least partially offset from the cutting groove 113.

[0105] The entire cutting assembly 120 is arranged inside the accommodating cavity 112, and the second cutting knife 142a and the first cutting knife 142c can extend out of the accommodating cavity 112 through the cutting groove 113, so as to cut the winding material wrapped around the outer circumference of the shell 110. At least a part of the second cutting edge 142b is offset from the cutting groove 113, so that the winding material can be inserted into the cutting groove 113, and then inserted between the second cutting edge 142b and the first cutting edge 142d, so that the first cutting knife 142c can cooperate with the second cutting knife 142a during the rotation process to cut off the winding material.

[0106] A plurality of fixing grooves 114 may be provided in the accommodating cavity 112 , and the plurality of cutting members 140 may be respectively disposed in the plurality of fixing grooves 114 , that is, the second bearing 144 may be fixed in the fixing grooves 114 .

[0107] In the embodiment of the present application, the cutting assembly 120 is installed on the shell 110, and can rotate synchronously with the shell 110 during the rotation of the shell 110, so as to cut the winding material wound on the outer peripheral surface of the shell 110. The above details the specific structure and cutting method of the cutting assembly 120. The following will introduce in detail how the cutting assembly 120 is installed and arranged on the shell 110.

[0108] 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 .

[0109] The cleaning unit 150 is arranged outside the shell 110, that is, outside the accommodating cavity 112, and the cutting assembly 120 is installed outside the accommodating cavity 112, so that the shell 110 can play a certain protective role on the cutting assembly 120 and can minimize the damage of the external structure to the cutting assembly 120.

[0110] In addition, by installing the cutting assembly 120 inside the accommodating cavity 112 , the space outside the shell 110 does not need to be occupied, so that the structure of the entire cleaning roller brush 100 is more compact without increasing the diameter of the cleaning roller brush 100 .

[0111] Among them, at least part of the cutting portion 142 of the cutting member 140 is exposed outside the cutting groove 113, which means that at least part of the second cutting edge 142b and the first cutting edge 142d can be exposed outside the cutting groove 113. The second cutting edge 142b and the first cutting edge 142d can be extended from the cutting groove 113 to the outside of the accommodating cavity 112 in their entirety, or can be extended from the cutting groove 113 to the outside of the accommodating cavity 112 in part. Since the winding object is wound around the outer peripheral surface of the shell 110, the second cutting edge 142b and the first cutting edge 142d extend from the cutting groove 113 to the outside of the accommodating cavity 112, which facilitates the cutting of the winding object on the outer peripheral surface, and can effectively cut the winding object.

[0112] In some embodiments, the cutting groove 113 has a plurality of sub-grooves 113 a arranged at intervals, and along the extension direction of the housing 110 , parts of the sub-grooves 113 a of two adjacent cutting grooves 113 are connected.

[0113] The same cutting groove 113 has a plurality of spaced-apart sub-grooves 113a, that is, it can be considered that the same cutting groove 113 is divided into a plurality of spaced-apart sub-grooves 113a, and 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 accommodating cavity 112 to a certain extent, and play a certain protective role.

[0114] In the extension direction of the shell 110 (i.e., in the length direction of the shell 110), the cutting portion 142 of each cutting piece 140 is installed in the corresponding cutting groove 113, and cuts the area corresponding to the cutting groove 113. Some sub-grooves 113a of two adjacent cutting grooves 113 are connected, which means that the cutting areas of the two adjacent cutting pieces 140 are partially overlapped, that is, the multiple cutting pieces 140 can basically completely cover the entire shell 110, avoiding the occurrence of cutting blind spots as much as possible, thereby improving the cleaning effect of the entangled objects, and further improving the cleaning effect of the cleaning roller brush 100.

[0115] In addition, since the second cutting knife 142a has multiple second cutting blades 142b, and the second cutting knife 142a is fixed inside the accommodating cavity 112, the gap between two adjacent second cutting blades 142b can be set corresponding to the sub-groove 113a, that is, the multiple second cutting blades 142b and the multiple sub-grooves 113a are staggered, so that the winding material can pass through the sub-groove 113a and fall between two adjacent second cutting blades 142b. When cutting, the winding material is cut as much as possible below the second cutting blade 142b and the first cutting blade 142d, which can increase the force applied to the winding material and thereby improve the cutting effect.

[0116] See also Fig.14 and Fig.15 In some embodiments, a mounting portion 115 is protruding from the housing 110, and a cutting groove 113 is disposed on the mounting portion 115. Since the winding object is wound on the outer surface of the housing 110, the cutting groove 113 is disposed on the mounting portion 115 protruding from the housing 110, so that the cutting portion 142 (the second cutting edge 142b and the first cutting edge 142d) can extend from the outer surface of the housing 110, that is, the cutting portion 142 (the second cutting edge 142b and the first cutting edge 142d) can protrude from the outer surface of the housing 110, that is, can protrude from the winding position of the winding object, so that the cutting portion 142 (the second cutting edge 142b and the first cutting edge 142d) can cut the winding object.

[0117] The mounting portion 115 is mainly used to accommodate the cutting portion 142, and the shape of the mounting portion 115 can be adapted to the shape of the cutting portion 142. The cutting portion 142 is generally circular, and the mounting portion 115 can be configured in an arc shape, which can accommodate the cutting portion 142 while reducing the external dimensions as much as possible.

[0118] 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 to clean 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, so that the cleaning portion 150 cannot contact the floor and cannot clean the floor.

[0119] 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 , which may prevent the cleaning portion 150 from interfering with the ground during cleaning, causing the cleaning portion 150 to fail to clean the ground normally.

[0120] In some embodiments, the same cutting member 140 corresponds to two mounting portions 115 , the two mounting portions 115 corresponding to the same cutting member 140 are respectively arranged on opposite sides of the shell 110 , and the cleaning portion 150 is arranged between the two mounting portions 115 corresponding to the same cutting member 140 .

[0121] Since the cutting portion 142 of the cutting piece 140 is circular, the same cutting portion 142 corresponds to two mounting portions 115, and the two mounting portions 115 are respectively arranged on two opposite sides, that is, the same circle of winding can be cut from the cutting grooves 113 on the two mounting portions 115 by the same cutting portion 142, and the same cutting portion 142 can cut the same circle of winding twice, cutting the winding into a smaller length, which can reduce the risk of the winding being wound around the shell 110 again.

[0122] The cleaning portion 150 is disposed between two mounting portions 115 corresponding to the same cutting member 140 . The cleaning portion 150 can be arranged by utilizing the gap between the two mounting portions 115 of the same cutting member 140 , so that the structure of the entire cleaning roller brush 100 is more compact.

[0123] The housing 110 may include a detachably connected upper shell 116 and a lower shell 117. If the internal cutting assembly 120 needs to be repaired, the upper shell 116 and the lower shell 117 may be separated to expose the cutting assembly 120, and the cutting assembly 120 may be repaired or replaced.

[0124] To summarize, in the cleaning roller brush 100 provided in the embodiment of the present application, during the rotation of the shell 110, linear windings such as hair will be wound around the shell 110 along the rotation direction of the shell 110, and the rotation direction of the cutting member 140 is different from the rotation direction of the shell 110, so that the cutting direction of the cutting member 140 can have a certain angle with the winding direction of the winding on the shell 110, and the winding can be cut in the radial direction of the winding, thereby cutting off the winding on the shell 110, reducing the influence of the winding 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.

[0125] Based on the same utility model concept, the embodiment of the present application also provides a cleaning device, which includes a main body and the above-mentioned cleaning roller brush 100, and the cleaning roller brush 100 is installed on the main body. The main body is the main structure of the entire cleaning device, wherein the cleaning device can be a sweeping robot, a floor scrubber, a vacuum cleaner, etc.

[0126] See also Fig.15 and Fig.16 The cleaning device also includes a driving mechanism, and the cleaning roller brush 100 also includes a fixed portion 160 and a movable portion 170. The fixed portion 160 and the movable portion 170 are respectively arranged at two opposite ends of the shell 110. The fixed portion 160 is transmission-connected to the driving mechanism, and the movable portion 170 is rotationally connected to the main body.

[0127] The movable part 170 includes a core shaft 172 and a bearing sleeve 174 . The core shaft 172 is fixedly connected to the main body, and the bearing sleeve 174 is disposed between the core shaft 172 and the housing 110 , so that the housing 110 can rotate relative to the main body.

[0128] Based on the same utility model concept, the embodiment of the present application also provides a cleaning system, which includes a cleaning base station and the above-mentioned cleaning device. The cleaning base station can have the functions of charging the cleaning device, cleaning the cleaning device, collecting impurities of the cleaning device, etc.
