[0057] With the development of science and technology, cleaning equipment has become more and more popular, and most of the cleaning equipment realizes the cleaning function of the floor through the cleaning roller brush. In the cleaning process, the hair-like linear objects on the ground are easy to wind around the outer circumference of the cleaning roller brush. If there are too many winding objects, it will affect the cleaning function, and even cause the cleaning roller brush to stop and damage the machine. Therefore, the embodiments of the present application provide a cleaning roller brush, a cleaning equipment and a cleaning system. The cleaning roller brush, the cleaning equipment and the cleaning system provided by the embodiments of the present application can automatically clean the winding objects wound on the cleaning roller brush during the cleaning process, reduce the influence of the winding objects on the cleaning roller brush, improve the working effect of the cleaning roller brush, and improve the service life of the cleaning roller brush.

[0058] The present application will be described below in conjunction with the drawings and specific embodiments:

[0059] Please refer to FIG. 1, the embodiments of the present application provide a cleaning roller brush 100, the cleaning roller brush 100 provided by the embodiments of the present application is installed on the cleaning equipment, and is mainly used for cleaning the to-be-cleaned object. The cleaning roller brush 100 provided by the embodiments of the present application can automatically clean the winding objects wound on the cleaning roller brush 100 during the cleaning process, reduce the influence of the winding objects 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.

[0060] Please refer to FIG. 1 and FIG. 2, in the embodiments of the present application, the cleaning roller brush 100 includes a cutting assembly 130, a shell 110, and a cleaning part 120 installed on the shell 110, wherein the cutting assembly 130 is installed in the shell 110; the cleaning part 120 can guide the winding objects to the cutting assembly 130, and the cutting assembly 130 is used for cutting the winding objects.

[0061] The shell 110 is the main body of the entire cleaning roller brush 100, and provides a mounting basis for the cleaning part 120, the cutting assembly 130 and the like. The shell 110 is approximately a cylinder, can be connected with the driving mechanism of the cleaning equipment, and can rotate relative to the main body of the cleaning equipment under the driving of the driving mechanism. The cleaning part 120 is installed on the outer circumferential surface of the shell 110, and is mainly used for contacting the ground and cleaning the ground during the rotation of the shell 110.

[0062] The cleaning portion 120 can be in a strip shape, and the cleaning portion 120 can be arranged along the extension direction of the housing 110. Specifically, the cleaning portion 120 can be arranged in a straight line along the extension direction of the housing 110, or arranged in an arc shape along the extension direction of the housing 110, or arranged in a spiral shape along the extension direction of the housing 110. The specific arrangement manner is not limited. The cleaning portion 120 can be provided in multiple numbers, and the multiple cleaning portions 120 can be arranged on the circumference of the housing 110 in a spaced manner. The shapes of any two cleaning portions 120 can be the same or different.

[0063] The cleaning portion 120 can guide the winding object to the cutting assembly 130. This means that the cleaning portion 120 can guide the winding object to the position of the cutting assembly 130, i.e., the cleaning portion 120 can guide the winding object to the cutting region of the cutting assembly 130.

[0064] During the rotation of the cleaning roller brush 100 driven by the cleaning device, the hair and other linear winding objects can be wound on the outer circumferential surface of the housing 110 due to the rotation of the housing 110. Since the housing 110 is in a strip shape, the winding object can be wound at different positions of the housing 110. After the cutting assembly 130 is installed on the housing 110, the position of the cutting assembly 130 on the housing 110 is fixed, so that the cutting assembly 130 can only cut the winding object in the cutting region of the cutting assembly 130. The cleaning portion 120 can guide the winding object to the cutting assembly 130, so that the winding object wound at different positions of the housing 110 can be guided into the cutting region of the cutting assembly 130, so that the cutting assembly 130 can cut the winding object, thereby avoiding the winding of the winding object on the housing 110 as much as possible, reducing the influence of the winding object on the cleaning roller brush 100, improving the working effect of the cleaning roller brush 100, and prolonging the service life of the cleaning roller brush 100.

[0065] In some embodiments, the cleaning portion 120 is protruded from the outer circumferential surface of the housing 110. The winding object is wound on the outer circumferential surface of the cleaning portion 120 (i.e., the cleaning portion 120 is away from the top surface of the housing 110). Most of the cleaning portion 120 has a certain elasticity. The winding object wound on the cleaning portion 120 can cause the cleaning portion 120 to deform, thereby cleaning the surface to be cleaned. The cleaning portion 120 can guide the winding object to the cutting assembly 130, so that the winding object wound at different positions of the cleaning portion 120 can be guided into the cutting region of the cutting assembly 130, so that the cutting assembly 130 can cut the winding object, thereby avoiding the winding of the winding object on the cleaning portion 120 as much as possible, reducing the influence of the winding object on the cleaning roller brush 100, improving the working effect of the cleaning roller brush 100, and prolonging the service life of the cleaning roller brush 100.

[0066] The cutting direction of the cutting assembly 130 can be different from the rotating direction of the shell 110. Since the winding direction of the winding object is the same as the rotating direction of the shell 110, it can be known that the cutting direction of the cutting assembly 130 is different from the winding direction of the winding object, that is, the cutting direction of the cutting assembly 130 is different from the length direction of the linear winding object. The cutting direction of the cutting assembly 130 is different from the length direction of the winding object. During the rotation of the cutting assembly 130 relative to the shell 110, the cutting direction of the cutting assembly 130 at least has a component along the radial direction of the winding object, so that the cutting assembly 130 can cut the winding object, as much as possible to avoid the winding of the winding object on the shell 110, reduce the influence of the winding object 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.

[0067] In some embodiments, the cleaning part 120 is at least partially arranged in a spiral.

[0068] The cleaning part 120 is at least partially arranged in a spiral, which means that the cleaning part 120 can be partially arranged in a spiral or entirely arranged in a spiral. During the synchronous rotation of the cleaning part 120 and the shell 110, the winding object moves along with the spiral cleaning part 120.

[0069] Since the cleaning part 120 is arranged in a spiral along the extension direction (axial direction) of the shell 110, the winding object can move in the extension direction (axial direction) of the shell 110, and then move into the cutting area of the cutting assembly 130, so that the cutting assembly 130 can cut the winding object, as much as possible to avoid the winding of the winding object on the shell 110, reduce the influence of the winding object 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.

[0070] The cleaning part 120 can be arranged in multiple numbers, and the cutting assembly 130 can be arranged close to one of the cleaning parts 120, so that the distance between the cutting assembly 130 and the cleaning part 120 is small. In the case that the winding object moves along with the spiral cleaning part 120 in the extension direction of the shell 110, the distance between the winding object and the cutting assembly 130 is small, so that the cutting assembly 130 can cut the winding object as soon as possible, reduce the winding time of the winding object on the cleaning roller brush 100, and then reduce the influence of the winding object on the cleaning effect of the cleaning roller brush 100.

[0071] The cutting assembly 130 is arranged close to one of the cleaning parts 120, and the distance between the cutting assembly 130 and the cleaning part 120 is very small, which can be ignored.

[0072] Referring to FIG. 2, in some embodiments, the cleaning part 120 comprises a first cleaning section 122 and a second cleaning section 123, the first cleaning section 122 and the second cleaning section 123 are sequentially arranged along the extension direction of the housing 110, the first cleaning section 122 and the second cleaning section 123 are opposite in rotation direction, and the cutting assembly 130 is arranged close to the first cleaning section 122 and the second cleaning section 123.

[0073] The sequential arrangement of the first cleaning section 122 and the second cleaning section 123 along the extension direction of the housing 110 means that the first cleaning section 122 and the second cleaning section 123 are arranged along the extension direction of the housing 110, the first cleaning section 122 and the second cleaning section 123 are located at different positions of the housing 110 in the extension direction of the housing 110, and the first cleaning section 122 and the second cleaning section 123 are arranged staggered in the axial direction of the housing 110.

[0074] The rotation direction of the first cleaning section 122 and the second cleaning section 123 is related to the rotation direction of the housing 110. Taking the first cleaning section 122 as an example, the first cleaning section 122 has one end close to the second cleaning section 123 and one end away from the second cleaning section 123. For convenience of description, the end close to the second cleaning section 123 is defined as the first end, and the end away from the second cleaning section 123 is defined as the second end. In the rotation direction of the housing 110, the second end is located in front of the first end, so that in the process of rotation of the housing 110, the entanglement can move from the second end to the first end, thereby guiding the entanglement into the cutting area of the cutting assembly 130.

[0075] Similarly, the second cleaning section 123 is arranged in the same way as the first cleaning section 122. The end of the second cleaning section 123 close to the first cleaning section 122 is defined as the third end, and the end away from the first cleaning section 122 is defined as the fourth end. In the rotation direction of the housing 110, the fourth end is located in front of the third end, so that in the process of rotation of the housing 110, the entanglement can move from the fourth end to the third end, thereby guiding the entanglement into the cutting area of the cutting assembly 130.

[0076] Since the first cleaning section 122 and the second cleaning section 123 are opposite in rotation direction, during the synchronous rotation of the cleaning part 120 and the shell 110, the first cleaning section 122 and the second cleaning section 123 are opposite in the guiding direction of the winding object, the winding object on the shell 110 can be guided to the middle region of the shell 110, so that the winding object on other positions of the shell 110 can move to the middle region of the shell 110 as much as possible, and the cutting assembly 130 can be arranged at the middle position of the shell 110, so that the winding object on other positions of the shell 110 can be guided to the cutting assembly 130 under the guidance of the cleaning part 120. In this way, only one set of cutting assemblies 130 can be arranged on the shell 110, and the winding object on other positions of the shell 110 can be guided to the cutting assembly 130 by the cleaning part 120, so that the number of cutting assemblies 130 can be reduced, and the cost can be reduced.

[0077] The cutting region of the cutting assembly 130 refers to the range in which the cutting assembly 130 can cut the winding object.

[0078] In some embodiments, the first cleaning section 122 and the second cleaning section 123 are arranged at intervals, and part of the cutting assembly 130 is located between the first cleaning section 122 and the second cleaning section 123.

[0079] Part of the cutting assembly 130 is located between the first cleaning section 122 and the second cleaning section 123, which means that part of the cutting assembly 130 can be located in the region corresponding to the gap between the first cleaning section 122 and the second cleaning section 123. In the extension direction of the shell 110, of course, another part of the cutting assembly 130 can be arranged to overlap at least one of the first cleaning section 122 and the second cleaning section 123.

[0080] Part of the cutting assembly 130 is arranged between the first cleaning section 122 and the second cleaning section 123, so that the winding object wound on the first cleaning section 122 can be guided to the cutting assembly 130 by the first cleaning section 122, and the winding object wound on the second cleaning section 123 can be guided to the cutting assembly 130 by the second cleaning section 123. That is, part of the cutting assembly 130 is arranged between the first cleaning section 122 and the second cleaning section 123, so that the same cutting assembly 130 can cut the winding object guided by the first cleaning section 122 and the second cleaning section 123 at the same time, which can reduce the number of cutting assemblies 130, and further can reduce the cost of the entire cleaning roller brush 100.

[0081] It should be noted that the part of the cutting assembly 130 between the first cleaning section 122 and the second cleaning section 123 does not mean that the part of the cutting assembly 130 is arranged in the gap between the first cleaning section 122 and the second cleaning section 123. The shell 110 is cylindrical, the cleaning part 120 is arranged on the outer peripheral wall of the shell 110, the gap between the first cleaning section 122 and the second cleaning section 123 corresponds to a circumferential surface, and the part of the cutting assembly 130 between the first cleaning section 122 and the second cleaning section 123 means that the part of the cutting assembly 130 is arranged on the circumferential surface corresponding to the gap (the area corresponding to the gap).

[0082] In some embodiments, the first cleaning section 122 has a first guide surface 122a at one end close to the second cleaning section 123.

[0083] The first cleaning section 122 is convex on the outer peripheral surface of the shell 110, and there is a certain height difference between the top surface of the first cleaning section 122 and the outer surface of the shell 110. The cutting assembly 130 is also arranged on the shell 110, so that there can be a certain height difference between the top surface of the first cleaning section 122 and the cutting assembly 130. The first guide surface 122a is arranged at the end of the first cleaning section 122 close to the second cleaning section 123, so that the winding on the first cleaning section 122 can be almost completely guided into the cutting area of the cutting assembly 130, reducing the risk of guiding the winding out of the cutting area of the cutting assembly 130, so that the winding can be almost completely cut, and the winding on the shell 110 is avoided as much as possible, reducing the influence of the winding on the cleaning roller brush 100, improving the working effect of the cleaning roller brush 100, and prolonging the service life of the cleaning roller brush 100.

[0084] The first guide surface 122a can be inclined, and the height of the first guide surface 122a relative to the shell 110 gradually decreases in the direction close to the second cleaning section 123.

[0085] In some embodiments, the second cleaning section 123 has a second guide surface 123a at one end close to the first cleaning section 122.

[0086] Similarly, the second cleaning section 123 is arranged on the outer circumferential surface of the housing 110, and the top surface of the second cleaning section 123 is higher than the outer surface of the housing 110. The cutting assembly 130 is arranged on the housing 110, so that the top surface of the second cleaning section 123 is higher than the cutting assembly 130. A second guide surface 123a is arranged at the end of the second cleaning section 123 close to the first cleaning section 122, so that the winding object on the second cleaning section 123 can be almost completely guided into the cutting area of the cutting assembly 130, reducing the risk of guiding the winding object out of the cutting area of the cutting assembly 130, so that the winding object can be almost completely cut, and the winding of the winding object on the housing 110 is avoided as much as possible, reducing the influence of the winding object on the cleaning roller brush 100, improving the working effect of the cleaning roller brush 100, and prolonging the service life of the cleaning roller brush 100.

[0087] The second guide surface 123a can be inclined, and the height of the second guide surface 123a relative to the housing 110 gradually decreases in the direction close to the first cleaning section 122.

[0088] In some embodiments, the first cleaning section 122 and the second cleaning section 123 are integrally formed, and the cutting assembly 130 is arranged at the connection between the first cleaning section 122 and the second cleaning section 123.

[0089] The first cleaning section 122 and the second cleaning section 123 can be an integral whole, and the integral whole of the first cleaning section 122 and the second cleaning section 123 is approximately v-shaped due to the opposite rotation directions of the first cleaning section 122 and the second cleaning section 123. The cutting assembly 130 is arranged at the connection between the first cleaning section 122 and the second cleaning section 123, which means that the cutting assembly 130 can be arranged on the circumference at the connection between the first cleaning section 122 and the second cleaning section 123.

[0090] The cutting assembly 130 is arranged at the connection between the first cleaning section 122 and the second cleaning section 123, which means that the cutting assembly 130 is arranged at the end of the first cleaning section 122 and the second cleaning section 123. Due to the spiral arrangement of the cleaning part 120 along the extension direction of the housing 110 (the axial direction of the housing 110), the winding object can move in the extension direction of the housing 110 (the axial direction of the housing 110), and then the winding object can move into the cutting area of the cutting assembly 130, so that the cutting assembly 130 can cut the winding object, the winding of the winding object on the housing 110 is avoided as much as possible, the influence of the winding object on the cleaning roller brush 100 is reduced, the working effect of the cleaning roller brush 100 is improved, and the service life of the cleaning roller brush 100 is prolonged.

[0091] The helical parameters of the first cleaning section 122 of the plurality of cleaning sections 120 can be the same or different. Similarly, the helical parameters of the second cleaning section 123 of the plurality of cleaning sections 120 can be the same or different. No specific limitation is made.

[0092] The helical parameters include the diameter, the pitch, and the inclination angle of the helix, and the like. The helical parameters being the same means that at least one of the diameter, the pitch, and the inclination angle of the helix is the same.

[0093] In some embodiments, the cleaning roller brush 100 further comprises a guide portion 140 mounted to the housing 110. The guide portion 140 is configured to guide the entanglement to the cutting assembly 130.

[0094] The guide portion 140 is mounted to the outer surface of the housing 110 and is configured to guide the entanglement to the cutting assembly 130. Since the entanglement is mostly linear entanglement such as hair, the guide portion 140 can be made of the same material or similar material as the entanglement. Thus, the entanglement can more easily follow the guide portion 140, i.e., the guide portion 140 can more easily guide the entanglement than the cleaning portion 120. Thus, the difficulty of guiding the entanglement is reduced, and the entanglement can be more easily guided to the cutting region of the cutting assembly 130. Thus, the risk of the entanglement being entangled on the cleaning portion 120 is reduced, and the influence of the entanglement on the working of the cleaning roller brush 100 is reduced.

[0095] That is, the cleaning portion 120 can play a guiding role, and the guide portion 140 can also play a guiding role. Under the dual action of the guide portion 140 and the cleaning portion 120, the guiding effect of the entanglement is improved, and the entanglement at different positions of the housing 110 can be as much as possible guided to the cutting assembly 130. Thus, the risk of the entanglement being entangled on the cleaning portion 120 is reduced, and the influence of the entanglement on the working of the cleaning roller brush 100 is reduced.

[0096] In some embodiments, the guide portion 140 comprises a plurality of guide portions 140 arranged in a helix. The plurality of guide portions 140 can be arranged in a helix along the extension direction of the housing 110 (the axial direction of the housing 110). Since the plurality of guide portions 140 are arranged in a helix along the extension direction of the housing 110 (the axial direction of the housing 110), the entanglement can move along the extension direction of the housing 110 (the axial direction of the housing 110), and thus the entanglement can move to the cutting region of the cutting assembly 130. Thus, the cutting assembly 130 can cut the entanglement, the entanglement on the housing 110 can be avoided as much as possible, the influence of the entanglement on the cleaning roller brush 100 is reduced, the working effect of the cleaning roller brush 100 is improved, and the service life of the cleaning roller brush 100 is also improved.

[0097] The cleaning part 120 is also arranged in a spiral, and the spiral parameters of the plurality of guide parts 140 can be the same as the spiral parameters of the cleaning part 120. The spiral parameters of the plurality of guide parts 140 being the same as the spiral parameters of the cleaning part 120 can make the guide directions of the cleaning part 120 and the guide part 140 consistent, so that the winding object can move in one direction, i.e., toward the cutting assembly 130, so that the winding object can be quickly guided to the cutting assembly 130 and then cut off by the cutting assembly 130.

[0098] The spiral parameters include the diameter, pitch, and inclination angle of the spiral, and the spiral parameters of the plurality of guide parts 140 being the same as the spiral parameters of the cleaning part 120 means that at least one of the diameter, pitch, and inclination angle of the spiral is the same.

[0099] Please refer to FIG. 3. In some embodiments, the cutting assembly 130 includes a transmission part 150 and a cutting part 160 in transmission connection with the transmission part 150. The transmission part 150 is fixedly connected with the shell 110, and the cutting part 160 is rotationally connected with the shell 110.

[0100] The transmission part 150 is fixed to the shell 110 and is in transmission connection with the cutting part 160. During the rotation of the shell 110 driven by the driving mechanism of the cleaning device, the transmission part 150 rotates with the shell 110, so that the transmission part 150 can drive the cutting part 160 to rotate relative to the shell 110. The transmission part 150 mainly serves to drive the cutting part 160 to rotate relative to the shell 110, and the cutting part 160 is mainly used to cut the winding object.

[0101] In some embodiments, the transmission part 150 is arranged along the extension direction of the shell 110, and the cutting direction of the cutting part 160 is arranged at an angle with the rotation direction of the shell 110.

[0102] The cutting direction of the cutting part 160 can be considered as the rotation direction of the cutting part 160 relative to the shell 110. The cutting direction of the cutting part 160 is arranged at an angle with the rotation direction of the shell 110, i.e., the rotation direction of the cutting part 160 is different from the rotation direction of the shell 110. During the rotation of the shell 110, the winding object such as hair will be wound on the shell 110 along the rotation direction of the shell 110, and the rotation direction of the cutting part 160 is different from the rotation direction of the shell 110, so that the cutting direction of the cutting part 160 can have a certain angle with the winding direction of the winding object on the shell 110, and the winding object can be cut in the radial direction of the winding object, so that the winding object on the shell 110 can be cut off, the influence of the winding object on the cleaning roller brush 100 is reduced, the working effect of the cleaning roller brush 100 is improved, and the service life of the cleaning roller brush 100 is improved.

[0103] The transmission member 150 is fixedly installed on the shell 110, and the transmission member 150 and the shell 110 do not move. It can be considered that the transmission member 150 and the shell 110 are an integral whole. In the process of rotating the shell 110, the transmission member 150 rotates with the shell 110. The rotation of the shell 110 can drive the rotation of the transmission member 150, and it is not necessary to separately drive the rotation of the transmission member 150 by setting another driving mechanism, thereby reducing the number of parts of the cleaning roller brush 100 and reducing the cost of the cleaning roller brush 100 to a certain extent. At the same time, since the driving mechanism of the transmission member 150 does not need to be separately set, the mounting position of the shell 110 does not need to be reserved, and the volume of the entire cleaning roller brush 100 can be reduced.

[0104] In the process of rotating the shell 110, the transmission member 150 rotates with the shell 110, that is, when the shell 110 starts to rotate, the transmission member 150 drives the cutting member 160 to rotate. That is, when the cleaning part 120 on the shell 110 starts to clean the ground, the transmission member 150 drives the cutting member 160 to rotate, and then cuts the winding object. In other words, when the cleaning roller brush 100 starts to clean, the cutting member 160 rotates. If the winding object is wound on the shell 110 at the same time, the cutting member 160 can cut the winding object in time, and the situation that the shell 110 has more winding objects and affects the cleaning effect basically does not occur.

[0105] In addition, since the cutting member 160 rotates in the process of rotating the shell 110, when the winding object is wound on the shell 110, the cutting member 160 cuts the winding object. The winding object is cut as it is wound, that is, the winding object is cut when the number of winding objects is small. Since the number of winding objects is small, the cutting member 160 is easier to cut, the wear of the cutting member 160 is reduced, and the service life of the cutting member 160 is improved.

[0106] Please refer to FIG. 4. In some embodiments, the transmission member 150 includes a transmission shaft 151 and a first transmission part 152. The transmission shaft 151 is installed on the shell 110, and the first transmission part 152 is arranged along the extension direction of the shell 110. The first transmission part 152 is in transmission cooperation with the cutting member 160 and the transmission shaft 151.

[0107] Since the shell 110 is substantially a cylinder, the extension direction of the shell 110 refers to the length direction of the shell 110 (the axial direction of the shell 110), the rotating shaft and the first transmission part 152 are both installed inside the shell 110, and the transmission shaft 151 is arranged along the extension direction of the shell 110. Among them, the transmission shaft 151 is installed on the shell 110, and the transmission shaft 151 will drive the first transmission part 152 to rotate with the shell 110, that is, the rotating direction of the transmission shaft 151 is the same as the rotating direction of the shell 110, and the rotating direction of the cutting piece 160 is different from the rotating direction of the shell 110, so the cooperation of the first transmission part 152 and the cutting piece 160 needs to realize the turning of the cutting piece 160, thereby, a bevel gear can be arranged on the transmission shaft 151, which can be defined as a first bevel gear 151b, and the first transmission part 152 cooperating with the transmission shaft 151 is also provided with a bevel gear, which can be defined as a second bevel gear 152b, and the turning is realized through the cooperation of the first bevel gear 151b and the second bevel gear 152b.

[0108] Since the transmission shaft 151 is installed on the shell 110, a bearing can be arranged on the transmission shaft 151 for supporting and fixing the transmission shaft 151. In order to facilitate description, the bearing on the transmission shaft 151 is defined as a first bearing 151a, and the first bearing 151a is fixedly connected with the shell 110, mainly for installing and fixing the transmission shaft 151, and can support the transmission shaft 151.

[0109] In the extension direction of the shell 110, a first mounting groove 111 can be arranged, and the first bearing 151a is respectively installed in the first mounting groove 111, and the first bearing 151a is fixed on the shell 110 through the first mounting groove 111. The first mounting groove 111 can limit and fix the first bearing 151a, in addition to which other fixing structures can be arranged to fix the bearing on the shell 110. For example, the first bearing 151a and the shell 110 can be fixed by clamping or screws.

[0110] Among them, the number of first bearings 151a can be set according to the length of the transmission shaft 151. If the length of the transmission shaft 151 is relatively long, multiple first bearings 151a can be arranged, if the length of the transmission shaft 151 is relatively short, only one first bearing 151a can be arranged, and the number of first bearings 151a can not be specifically limited.

[0111] Please refer to FIG. 5, similarly, the first transmission part 152 needs to realize the transmission between the transmission shaft 151 and the cutting member 160, and the first transmission part 152 can be provided with a second bevel gear 152b matched with the transmission shaft 151, and a first transmission gear 152c matched with the cutting member 160. Similarly, in order to facilitate the installation of the first transmission part 152, a bearing can be arranged on the first transmission part 152 for supporting and fixing the first transmission part 152. In order to facilitate the description, the bearing matched with the first transmission part 152 is defined as a second bearing 152a, and a second mounting groove 112 can be arranged on the shell 110, and the second bearing 152a is mounted in the second mounting groove 112.

[0112] Since the cutting direction of the cutting member 160 is substantially along the length direction of the shell 110, the cutting member 160 is relatively long in the length direction of the shell 110, which may interfere with the transmission shaft 151 or the first transmission part 152. The first transmission part 152 can be arranged in different forms. Specifically, the first transmission part 152 can include a first transmission section 152d and a second transmission section 152e. The first transmission section 152d is provided with the second bevel gear 152b and the first transmission gear 152c, and the second bevel gear 152b is matched with the first bevel gear 151b, and the plurality of first transmission gears 152c are sequentially engaged. The number of the second transmission section 152e can also be set according to the diameter of the cutting member 160.

[0113] Please refer to FIG. 6, in some embodiments, the cutting member 160 includes a rotating shaft 161, a cutting section 162 and a second transmission part 163. The second transmission part 163 and the cutting section 162 are sleeved on the rotating shaft 161, the rotating shaft 161 is mounted on the shell 110, the cutting section 162 is at least partially in transmission connection with the rotating shaft 161, and the cutting section 162 is in transmission connection with the transmission member 150.

[0114] The rotating shaft 161 is in rotational connection with the shell 110, the cutting section 162 and the second transmission part 163 are both mounted on the rotating shaft 161, and the second transmission part 163 is in transmission connection with the first transmission part 152, so as to drive the rotating shaft 161 and the cutting section 162 to rotate relative to the shell 110.

[0115] In some embodiments, the extension direction of the rotating shaft 161 is arranged at an angle with the extension direction of the shell 110. That is, the cutting direction of the cutting section 162 is different from the rotational direction of the shell 110.

[0116] Among them, the cutting section 162 is mainly used for cutting the winding object. In the cutting process, the cutting section 162 can cut through a cutting edge, or two opposite cutting edges can cut the winding object.

[0117] Please refer to FIG. 7 and FIG. 8, in some embodiments, the cutting part 162 includes a first cutting knife 162a and a second cutting knife 162c, the second cutting knife 162c is fixedly connected with the shell 110, and the first cutting knife 162a is in transmission connection with the rotating shaft 161.

[0118] The first cutting knife 162a and the second cutting knife 162c are both sleeved on the rotating shaft 161, but only the first cutting knife 162a rotates with the rotating shaft 161, and the second cutting knife 162c is fixed on the shell 110. The transmission member 150 can drive the rotating shaft 161 to rotate the first cutting knife 162a through the engagement of the first transmission part 152 and the second transmission part 163, that is, the relative rotation between the first cutting knife 162a and the second cutting knife 162c is generated, so that the winding between the first cutting knife 162a and the second cutting knife 162c can be cut.

[0119] The first cutting knife 162a and the second cutting knife 162c move towards each other, and the cutting principle of the two is the same as that of a pair of scissors, so that the winding is subjected to force from two different directions, the acting force on the winding can be improved, the winding can be quickly cut off, and the cutting effect on the winding is improved.

[0120] In some embodiments, the second cutting knife 162c has a plurality of second cutting edges 162d, the plurality of second cutting edges 162d are arranged at intervals along the circumference of the second cutting knife 162c, the first cutting knife 162a has a plurality of first cutting edges 162b, the plurality of first cutting edges 162b are arranged at intervals along the circumference of the first cutting knife 162a, and the second cutting edges 162d and the first cutting edges 162b are oppositely arranged.

[0121] In the case of cooperation between the first cutting knife 162a and the second cutting knife 162c, during the rotation of the first cutting knife 162a following the rotating shaft 161, because the first cutting knife 162a has a plurality of first cutting edges 162b and the second cutting knife 162c has a plurality of second cutting edges 162d, the first cutting knife 162a can cut the winding multiple times through the cooperation of the plurality of second cutting edges 162d and the plurality of first cutting edges 162b during one rotation, and the cutting efficiency is improved.

[0122] Since the first cutting knife 162a and the second cutting knife 162c apply force to the winding from two different directions of the winding, the first cutting edge 162b and the second cutting edge 162d can cut the winding by applying smaller force respectively during cutting the winding. In other words, the first cutting edge 162b and the second cutting edge 162d are subjected to smaller reaction force of the winding respectively. Thus, the strength requirement of the first cutting knife 162a is lower than that of the case of having only one cutting knife, and the first cutting knife 162a can be provided in a disc shape with a smaller thickness. The first cutting knife 162a can include a blade portion 162e and a first body 162f, the blade portion 162e is protruded from the first body 162f, and the first cutting edge 162b is provided on a side wall of the blade portion 162e.

[0123] Since each blade portion 162e has left and right sides, the first cutting edge 162b can be provided on both sides of each blade portion 162e, or the first cutting edge 162b can be provided on one side of each blade portion 162e. In the case of providing the first cutting edge 162b on one side of each blade portion 162e, the first cutting edges 162b of the plurality of blade portions 162e can be provided in the same manner, i.e., all of the first cutting edges 162b can be provided on the left side of the blade portion 162e, or all of the first cutting edges 162b can be provided on the right side of the blade portion 162e.

[0124] Since the first cutting edge 162b is subjected to smaller reaction force of the winding, the single blade portion 162e is also subjected to smaller force, and thus the strength requirement of the single blade portion 162e is not high. The width of the single blade portion 162e can be set smaller, and the length of the single blade portion 162e protruded from the first body 162f can be set shorter.

[0125] Similarly, the strength requirement of the second cutting knife 162c is lower than that of the case of having only one cutting knife, and the second cutting knife 162c can also be provided in a disc shape with a smaller thickness. The length of the second cutting edge 162d can also be set smaller.

[0126] Please refer to FIG. 9, in some embodiments, the cutting member 160 further comprises a third bearing 164 sleeved on the rotating shaft 161 and between the first cutting knife 162a and the shell 110, and an elastic member 165 arranged between the shell 110 and the third bearing 164. The elastic member 165 abuts against the second cutting knife 162c and the shell 110 at both ends, respectively, and can provide a restoring force for the first cutting knife 162a to contact the second cutting knife 162c, so that the first cutting knife 162a and the second cutting knife 162c always have a certain pressure therebetween, and can always maintain contact during the movement of the first cutting edge 162b and the second cutting edge 162d, thereby improving the force applied to the winding and quickly cutting off the winding.

[0127] The foregoing details the case where the cutting part 162 has two cutting knives, of course, in addition to this, in other embodiments, the cutting part 162 can be provided with only one cutting knife, i.e. the cutting part 162 comprises the first cutting knife 162a, and the winding is cut only by the moving first cutting knife 162a. When the cutting part 162 is provided with only the first cutting knife 162a, the mounting position and movement mode of the first cutting knife 162a are the same as when the first cutting knife 162a and the second cutting knife 162c are provided at the same time, and the description of other structures in this application does not separately list the arrangement position when the cutting part 162 is provided with only the first cutting knife 162a. The mounting position and movement mode of the first cutting knife 162a when the first cutting knife 162a and the second cutting knife 162c are provided at the same time can be analogized accordingly.

[0128] Please refer to FIG. 10, in some embodiments, the shell 110 has a receiving cavity 113 and a cutting groove 114 communicating with the receiving cavity 113, the transmission member 150 and the cutting member 160 are arranged in the receiving cavity 113, and the second cutting edge 162d is at least partially arranged in a staggered manner with the cutting groove 114.

[0129] The entire cutting assembly 130 is arranged inside the receiving cavity 113, and the second cutting knife 162c and the first cutting knife 162a can extend out of the receiving cavity 113 through the cutting groove 114, thereby cutting the winding wound on the outer circumference of the shell 110. The second cutting edge 162d is at least partially arranged in a staggered manner with the cutting groove 114, so that the winding can be clamped into the cutting groove 114 and then clamped between the second cutting edge 162d and the first cutting edge 162b, so that the first cutting knife 162a can cooperate with the second cutting knife 162c during rotation to cut off the winding.

[0130] A fixing groove 115 can be arranged in the receiving cavity 113, and the cutting member 160 is arranged in the fixing groove 115, i.e. the third bearing 164 is fixed in the fixing groove 115.

[0131] In the embodiment of the present application, the cutting assembly 130 is mounted on the housing 110 and can rotate synchronously with the housing 110 during rotation of the housing 110, thereby cutting the winding object wound on the outer circumferential surface of the housing 110. The specific structure and cutting mode of the cutting assembly 130 are described in detail above, and how the cutting assembly 130 is mounted and arranged on the housing 110 will be described in detail below.

[0132] In some embodiments, the housing 110 includes a receiving cavity 113 and a cutting groove 114 in communication with the receiving cavity 113, the cutting assembly 130 is mounted in the receiving cavity 113, and the cutting portion 162 of the cutting member 160 is at least partially exposed to the cutting groove 114.

[0133] The cleaning part 120 is arranged outside the housing 110, i.e., outside the receiving cavity 113, and the cutting assembly 130 is mounted outside the receiving cavity 113, so that the housing 110 can protect the cutting assembly 130 to some extent and reduce damage to the cutting assembly 130 by external structures as much as possible.

[0134] In addition, mounting the cutting assembly 130 inside the receiving cavity 113 can avoid occupying space outside the housing 110, so that the structure of the entire cleaning roller brush 100 is more compact and the diameter of the cleaning roller brush 100 is not increased additionally.

[0135] In the embodiment of the present application, the cutting assembly 130 is mounted on the housing 110 and can rotate synchronously with the housing 110 during rotation of the housing 110, thereby cutting the winding object wound on the outer circumferential surface of the housing 110. The specific structure and cutting mode of the cutting assembly 130 are described in detail above, and how the cutting assembly 130 is mounted and arranged on the housing 110 will be described in detail below.

[0136] In some embodiments, the cutting groove 114 has a plurality of sub-grooves 114a arranged at intervals, i.e., the cutting groove 114 can be considered to be divided into a plurality of sub-grooves 114a arranged at intervals, and the width of each sub-groove 114a is relatively small compared to the width of the cutting groove 114, i.e., the width of a single sub-groove 114a is relatively small, which can prevent relatively large impurities from entering the receiving cavity 113 to some extent and play a certain protective role.

[0137] In addition, since the second cutting knife 162c has a plurality of second cutting edges 162d and is fixed inside the accommodating cavity 113, the gap between two adjacent second cutting edges 162d can be arranged corresponding to the sub-groove 114a, that is, the plurality of second cutting edges 162d are staggered with the plurality of sub-grooves 114a, so that the winding object can fall between two adjacent second cutting edges 162d through the sub-groove 114a, and the second cutting edge 162d and the first cutting edge 162b cut the winding object from below as much as possible, which can improve the force applied to the winding object and further improve the cutting effect.

[0138] In some embodiments, the housing 110 is provided with a mounting portion 116, and the cutting groove 114 is arranged on the mounting portion 116. Since the winding object is wound on the outer surface of the housing 110, the cutting groove 114 is arranged on the mounting portion 116 protruding from the housing 110, so that the cutting portion 162 (the second cutting edge 162d and the first cutting edge 162b) can protrude from the outer surface of the housing 110, that is, the cutting portion 162 (the second cutting edge 162d and the first cutting edge 162b) can protrude from the winding position of the winding object, so that the cutting portion 162 (the second cutting edge 162d and the first cutting edge 162b) can cut the winding object.

[0139] The mounting portion 116 is mainly used to accommodate the cutting portion 162, and the shape of the mounting portion 116 can be matched with the shape of the cutting portion 162. If the cutting portion 162 is approximately circular, the mounting portion 116 can be arranged in a circular arc shape, which can accommodate the cutting portion 162 while minimizing the external size.

[0140] In some embodiments, the height of the mounting portion 116 protruding from the housing 110 is less than the height of the cleaning portion 120 protruding from the housing 110. The cleaning portion 120 is mainly used for cleaning the ground. If the height of the mounting portion 116 protruding from the housing 110 is greater than the height of the cleaning portion 120 protruding from the housing 110, the mounting portion 116 will contact the ground during the rotation of the housing 110, so that the cleaning portion 120 cannot contact the ground and cannot clean the ground.

[0141] The height of the mounting portion 116 protruding from the housing 110 is less than the height of the cleaning portion 120 protruding from the housing 110, which can avoid interference with the ground during the cleaning process of the cleaning portion 120, so that the cleaning portion 120 cannot normally clean the ground.

[0142] In some embodiments, the cutting member 160 corresponds to two mounting portions 116, and the two mounting portions 116 are arranged on opposite sides of the housing 110, respectively. The cleaning portion 120 can be arranged between the two mounting portions 116.

[0143] Since the cutting part 162 of the cutting piece 160 is circular, the cutting part 162 corresponds to two mounting parts 116 arranged at opposite sides, that is, the same winding can be cut by the same cutting part 162 from the cutting grooves 114 on the two mounting parts 116, the same cutting part 162 can cut the same winding twice to cut the winding into smaller lengths, which can reduce the risk of winding on the shell 110 again.

[0144] The cleaning part 120 can be arranged between the two mounting parts 116 corresponding to the cutting piece 160, so that the cleaning part 120 is arranged in the gap between the two mounting parts 116 of the same cutting piece 160, so that the structure of the whole cleaning roller brush 100 is more compact.
