DETAILED DESCRIPTION

[0036] ​For the convenience of understanding the utility model, the utility model will be explained in more detail below in combination with the drawings and specific embodiments. It should be noted that when an element is described as being "connected" to another element, it can be directly on the other element or one or more intervening elements can be present therebetween. The terms "upper", "lower", "left", "right", "upper end", "lower end", "top" and "bottom" and the like used in the specification indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model. In addition, the terms "first", "second", etc. are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0037] Unless otherwise defined, all technical and scientific terms used in the specification are the same as those commonly understood by those skilled in the art to which the utility model belongs. The terms used in the specification of the utility model are only for the purpose of describing the specific embodiments and are not used to limit the utility model.

[0038] At present, the cleaning robot mainly realizes the cleaning of garbage in the cleaning area such as the ground and the blanket through the rotation of the roller brush, so as to sweep the garbage into the dust box of the cleaning robot. However, in the process of the rotation of the roller brush, the brush bar on the roller brush is easy to be entangled with hair and other filamentous entanglements, which affects the cleaning efficiency and cleaning effect and increases the cleaning difficulty of the brush bar on the roller brush.

[0039] In order to reduce the entanglements on the brush bar, a comb structure can be arranged in the roller brush support of the cleaning robot, and in the process of the rotation of the roller brush, the comb structure interferes with the brush bar on the roller brush, so as to strip off the entanglements on the brush bar.

[0040] However, in this process, on the one hand, the rotation of the brush bar will hit the comb structure, which is easy to cause the brush bar to be damaged and generate a large noise, and on the other hand, the rotation of the brush bar will be in close contact with the comb structure, which is easy to make part of the hair and other entanglements more closely adhere to the brush bar and not easy to be cleaned, the stripping effect of the entanglements is poor, and the cleaning effect of the ground and the blanket is affected.

[0041] To solve the above problems, the utility model embodiment provides a roller brush assembly and a cleaning robot, which aims to balance the cleaning effect on the ground and the blanket and the stripping effect of the entanglements on the brush bar, and reduce the noise during cleaning operation.

[0042] The utility model will be described in detail below in combination with the drawings Figures 1 to 8 The roller brush assembly 20 and the cleaning robot 100 provided by the utility model embodiment will be described in detail.

[0043] Please refer toFigure 1 The utility model embodiment provides a kind of cleaning robot 100, and cleaning robot 100 includes body 10 and is set on the brush roller assembly 20 of body 10.

[0044] Specifically, cleaning robot 100 can move on the surface to be cleaned to clean the area passed by it, wherein the surface to be cleaned can be the surface of ground, carpet or blanket etc..Cleaning robot 100 can be generally circular but not limited to this, for example, cleaning robot 100 can also be D-shaped, square etc.

[0045] Cleaning robot 100 includes body 10 and brush roller assembly 20, and brush roller assembly 20 is usually installed at the bottom of body 10 to facilitate contact with the surface to be cleaned, and optionally, motor and dust box (not shown) etc. are also provided on body 10, when cleaning operation is needed, motor drives the rotation of brush roller 22 in brush roller assembly 20, and through the rotation of brush roller 22, garbage on ground or blanket can be swept into dust box.

[0046] Please refer to Figures 2 to 6 , brush roller assembly 20 includes support 21, brush roller 22 and comb piece 23,

[0047] Brush roller 22 is detachably installed on support 21, and brush roller 22 includes roller 220 and first cleaning strip 221, and first cleaning strip 221 is arranged at the axial outer periphery of roller 220, and a plurality of avoiding openings 2210 are arranged at the end of first cleaning strip 221 away from roller 220; comb piece 23 is fixedly connected to the side of support 21 facing brush roller 22, and comb piece 23 includes a plurality of tooth portions 231, and a plurality of tooth portions 231 are arranged at intervals in the axial direction of roller 220, a plurality of avoiding openings 2210 correspond to a plurality of tooth portions 231 one by one, and a plurality of avoiding openings 2210 cooperate with a plurality of tooth portions 231 to clean the winding on brush roller 22.

[0048] Support 21 is usually fixedly installed at the bottom of body 10 (see Figure 4 ), and as a whole, brush roller assembly 20 is fixedly connected to body 10 through the support 21 of brush roller assembly 20, so that brush roller assembly 20 is installed on body 10 as a whole. Optionally, support 21 can be integrally formed with body 10, and in addition, support 21 can be fixedly installed on body 10 by clamping, threaded connection etc.

[0049] Support 21 is provided with receiving cavity 210 (see Figure 2), the roller brush 22 is rotatably mounted in the receiving chamber 210. The roller 220 may be cylindrical and rotatable along its own axis. A first cleaning bar 221 is disposed on the outer circumference of the roller 220 and may be arranged along the axial direction of the roller 220. When cleaning areas such as floors and carpets, the roller 220 drives the first cleaning bar 221 to move, causing it to contact the surface to be cleaned and sweep debris from the surface into the dust box.

[0050] The comb teeth 23 are arranged in the receiving chamber 210. For example, the comb teeth 23 can be fixedly connected to the inner wall of the receiving chamber 210. Optionally, the comb teeth 23 has a roughly strip-shaped structure and is arranged along the axial direction of the roller 220. During the rotation of the roller 220, the first cleaning strip 221 on the roller 220 cooperates with the comb teeth 23 to peel off the entanglement attached to the first cleaning strip 221.

[0051] like Figure 5 and Figure 6 As shown, the comb-tooth member 23 is provided with a plurality of teeth 231 at intervals along the axial direction of the roller 220, and the end of the first cleaning strip 221 facing the comb-tooth member 23 is provided with a plurality of avoidance openings 2210 that cooperate with the plurality of teeth 231. The plurality of avoidance openings 2210 are adapted to the size of the plurality of teeth 231 and the positions correspond one to one.

[0052] During the rotation of the roller brush 22, the avoidance opening 2210 on the first cleaning bar 221 can avoid the teeth 231 of the comb member 23, allowing the first cleaning bar 221 to bypass the comb member 23, preventing the first cleaning bar 221 from colliding or rubbing with the comb member 23 and causing damage. This reduces the noise caused by the first cleaning bar 221 hitting the comb member 23 during the cleaning process, avoids increasing the load on the motor due to the first cleaning bar 221 hitting the comb member 23, and reduces the risk of motor stalling. At the same time, entangled objects on the first cleaning bar 221 will come into contact with the comb member 23, and the comb member 23 can effectively peel off and clean entangled objects such as hair attached to the first cleaning bar 221, improving the cleaning effect of the entangled objects on the first cleaning bar 221 and ensuring the cleaning effect on areas such as floors and carpets.

[0053] In some embodiments, a plurality of first cleaning strips 221 may be provided, and the plurality of first cleaning strips 221 are evenly arranged along the circumference of the roller 220. During the rotation of the roller 220, each first cleaning strip 221 intermittently cooperates with the comb tooth member 23, thereby further improving the ability to clean the entangled objects on the first cleaning strip 221.

[0054] Optionally, there are multiple comb-tooth members 23 , and the multiple comb-tooth members 23 can increase the contact frequency between the entangled objects on the first cleaning bar 221 and the comb-tooth members 23 , thereby improving the cleaning efficiency of the entangled objects on the first cleaning bar 221 .

[0055] In some embodiments, the first cleaning strip 221 may be made of a relatively hard elastic material to ensure a cleaning effect on areas such as carpets and rugs.

[0056] In some embodiments, the first cleaning strip 221 can be a rubber strip. For example, the rubber strip can be made of rubber, silicone or other elastic materials, which has good adhesion and hardness. When cleaning carpets, blankets and other areas, the rubber strip can fit tightly to the surface of the carpets and blankets, thereby improving the cleaning effect of large and small particles of garbage and hair on carpets and blankets and other areas.

[0057] like Figure 4 and Figure 5 As shown, in some embodiments, the roller brush 22 further includes a second cleaning strip 222 , which is disposed on the periphery of the roller 220 , and the first cleaning strip 221 and the second cleaning strip 222 are spaced apart along the circumferential direction of the roller 220 .

[0058] The second cleaning strip 222 is a wool strip. Optionally, the wool strip can be made of nylon, polyester fiber, or other synthetic fibers. Compared to the first cleaning strip 221, the second cleaning strip 222 is made of a softer material and is more suitable for cleaning hard floors, such as tiles, wooden floors, marble, etc. The second cleaning strip 222 can effectively remove dust, fine particles, and debris from the floor without leaving scratches. It is understandable that during the cleaning process, the second cleaning strip 222 can also cooperate with the comb member 23, and the teeth 231 of the comb member 23 can penetrate into the second cleaning strip 222, thereby peeling off the entanglement on the second cleaning strip 222 through the comb member 23.

[0059] The first cleaning strip 221 and the second cleaning strip 222 are respectively provided on the outer circumferential surface of the roller 220, and the first cleaning strip 221 and the second cleaning strip 222 are spaced apart along the circumferential direction of the roller 220. The number of the first cleaning strip 221 and the number of the second cleaning strip 222 can be one or more, and the first cleaning strip 221 and the second cleaning strip 222 are alternately distributed along the circumferential direction of the roller 220. The first cleaning strip 221 can effectively clean areas such as carpets and blankets, while the second cleaning strip 222 can effectively clean hard floors. Thus, the cleaning effect of both hard floors and carpets and blankets can be taken into account, and it is suitable for a wider range of cleaning scenarios.

[0060] In some embodiments, the first cleaning strip 221 and the second cleaning strip 222 are in a V-shaped structure or a spiral structure, for example, the first cleaning strip 221 can be in a substantially V-shaped structure, and the second cleaning strip 222 can be in a substantially spiral structure.

[0061] During the process of cleaning the ground, the first cleaning strip 221 or the second cleaning strip 222 in a V-shaped structure can effectively gather the garbage on both sides to the center, and the first cleaning strip 221 or the second cleaning strip 222 in a spiral structure can generate a centripetal force when rotating to push the surrounding garbage to the spiral center. In this way, by adopting the V-shaped structure or the spiral structure for the first cleaning strip 221 and the second cleaning strip 222, the garbage gathering capacity and the cleaning effect of the cleaning robot 100 can be significantly improved.

[0062] In some embodiments, the comb tooth member 23 can be detachably installed on the support 21, for example, the comb tooth member 23 can be fixed on the support 21 by clamping, threaded connection, adhesion or the like, so as to facilitate the disassembly and assembly of the comb tooth member 23.

[0063] In specific use, the user can decide whether to install the comb tooth member 23 on the support 21 according to the actual cleaning environment, for example, in a cleaning environment with more hair, the user can install the comb tooth member 23 structure to better strip off the hair and other winding objects attached to the first cleaning strip 221 and the second cleaning strip 222, while in a cleaning environment with more particle garbage, the comb tooth member 23 is not required to be installed to avoid the particle garbage from being accumulated on the comb tooth member, affecting the cleaning effect, and also to avoid the interaction between the comb tooth member 23 and the first cleaning strip 221 and the second cleaning strip 222 to increase the resistance when the roller 220 rotates, further reducing the noise in the cleaning process.

[0064] Please refer to Figure 6 In some embodiments, the comb tooth member 23 includes a base plate 232 and a clamping portion 233 arranged on the side of the base plate 232 away from the tooth portion 231, the clamping portion 233 is clamped and matched with the support 21, and a plurality of tooth portions 231 are arranged on the side of the base plate 232 away from the clamping portion 233.

[0065] As Figure 6As shown, the base plate 232 is a long plate-like structure, and the clamping portion 233 is provided on one side of the base plate 232. The clamping portion 233 is engaged with the bracket 21 to achieve a fixed connection between the comb tooth member 23 and the bracket 21. Optionally, the base plate 232, the clamping portion 233 and the tooth portion 231 can be an integrally formed structure to ensure the structural reliability of the comb tooth member 23. The clamping portion 233 can be a columnar structure protruding from one side of the base plate 232. Correspondingly, the bracket 21 is provided with a clamping groove (not shown) that cooperates with the clamping portion 233. During assembly, the clamping portion 233 is inserted into the clamping groove to achieve installation of the comb tooth member 23 on the bracket 21. This method is simple to assemble and disassemble, and is convenient for maintenance and replacement of the comb tooth member 23.

[0066] It is understandable that, in other embodiments, the comb-tooth member 23 may also be configured as an integrally formed structure with the bracket 21 . In addition, the comb-tooth member 23 may not have the base plate 232 and the clamping portion 233 .

[0067] Optionally, the teeth 231 may be arranged at intervals or in a staggered manner on the base plate 232. The teeth 231 may be straight teeth or oblique teeth, that is, the teeth 231 may be arranged perpendicularly on the base plate 232 or obliquely on the base plate 232. For example, in some embodiments, the teeth 231 may be oblique teeth. Oblique teeth can provide a larger contact area with the entangled material, and the inclination angle of the oblique teeth can help the entangled material be peeled off better, thereby improving the cleaning effect.

[0068] like Figure 6 As shown, in some embodiments, the tooth portion 231 is a trapezoidal structure, and the size of the tooth portion 231 gradually decreases from one end of the tooth portion 231 close to the substrate 232 to the end of the tooth portion 231 away from the substrate 232. That is, the end of the trapezoidal tooth portion 231 connected to the substrate 232 is larger in size, and the end of the trapezoidal tooth portion 231 facing the roller 220 (avoidance opening 2210) is smaller in size.

[0069] On the one hand, the trapezoidal structure can provide a larger contact area and form a certain inclination angle, so that hair and other entanglements on the first cleaning strip 221 are easier to be peeled off. On the other hand, the trapezoidal tooth portion 231 has good structural strength. The trapezoidal tooth portion 231 is configured to have a smaller size at one end facing the avoidance opening 2210, so that the tooth portion 231 can be better embedded in the avoidance opening 2210 of the cleaning strip, avoiding the tooth portion 231 being larger at one end facing the avoidance opening 2210 and being stuck with the avoidance opening 2210.

[0070] See also Figure 2 、 Figure 4 、 Figure 7 and Figure 8 , Figure 8X represents the radial direction of the roller 220, in some embodiments, the bottom of the body 10 is provided with a battery accommodating cavity 11 (see Figure 7 ), and the battery accommodating cavity 11 is located on one side of the radial direction X of the roller 220, that is, on the upper side or the lower side of the roller 220 in the visual angle; the body 10 further comprises a battery cover 30, which is arranged on the bottom of the body 10 and corresponds to the position of the battery accommodating cavity 11. Figure 8

[0071] As shown in Figure 7 and Figure 8 , the battery accommodating cavity 11 is arranged adjacent to the support 21 and on one side of the radial direction of the roller 220, which helps to save the axial space of the cleaning robot 100 and improve the layout compactness.

[0072] The battery cover 30 is in a generally plate-shaped structure, which is mounted on the bottom of the body 10. The battery accommodating cavity 11 can be closed or opened through the battery cover 30. When the battery accommodating cavity 11 is in an open state, the user can install the battery into the battery accommodating cavity 11 or take out the battery in the battery accommodating cavity 11, which facilitates the disassembly and replacement of the battery. When the battery accommodating cavity 11 is closed through the battery cover 30, the battery cover 30 can protect the battery in the battery accommodating cavity 11 from water and dust.

[0073] In some embodiments, the roller brush assembly 20 further comprises a roller brush cover 24, which is arranged on the bottom of the body 10 and corresponds to the position of the support 21. The support 21 is provided with a roller brush cover mounting position for fixedly cooperating with the roller brush cover 24. Along the radial direction of the roller 220, the battery cover 30 partially overlaps with the roller brush cover 24 mounting position, which helps to reduce the transition space between the battery cover 30 and the roller brush cover 24, so that the layout of each component such as the battery, the roller brush assembly 20, etc. is more compact and reasonable, and the internal space of the cleaning robot 100 is saved.

[0074] The roller brush cover 24 is arranged on the bottom of the body 10, and the roller brush assembly 20 can be fixed and protected through the roller brush cover 24, so as to ensure the stability of the roller brush assembly 20 during work.

[0075] Optionally, one end of the roller brush cover 24 towards the battery cover 30 is fixedly connected with one end of the battery cover 30 towards the roller brush cover 24, and the roller brush cover 24 partially overlaps with the battery cover 30, which further reduces the transition space between the battery cover 30 and the roller brush cover 24, so that the layout of each component such as the battery, the roller brush assembly 20, etc. is more compact and reasonable, and the internal space of the cleaning robot 100 is saved.

[0076] Optionally, one end of the roller brush cover 24 towards the battery cover 30 is fixedly connected with one end of the battery cover 30 towards the roller brush cover 24 through buckling, screwing or other ways. ​

[0077] In some embodiments, the battery cover 30 is provided with a first plug-in part (not shown) at one end away from the roller brush cover 24, and a first plug-in slot 110 (see Figure 7 ) is formed on the groove wall of the battery accommodating cavity 11, and the first plug-in part can be plug-in matched with the first plug-in slot 110.

[0078] The battery cover 30 is provided with a second plug-in slot 31 (see Figure 4 ) at one end towards the roller brush cover 24, and the roller brush cover 24 is provided with a second plug-in part 41 at one end towards the battery cover 30, and the second plug-in part 41 can be plug-in matched with the second plug-in slot 31.

[0079] The roller brush cover 24 is provided with a clamping hook 42 (see Figure 2 ) at one end away from the battery cover 30, and a clamping slot 2100 (see Figure 7 ) is formed on the inner wall of the accommodating cavity 210, and the clamping hook 42 can be clamped matched with the clamping slot 2100.

[0080] In assembly, only the first plug-in part at one end of the battery cover 30 away from the roller brush cover 24 is inserted into the first plug-in slot 110, the battery cover 30 is closed to the battery accommodating cavity 11, then the second plug-in part 41 at one end of the roller brush cover 24 towards the battery cover 30 is inserted into the second plug-in slot 31, and the clamping hook 42 at one end of the roller brush cover 24 away from the battery cover 30 is clamped into the clamping slot 2100 on the inner wall of the accommodating cavity 210, and the assembly is completed. The double limiting and fixing of plug-in and clamping hook 42 in the embodiment makes the installation of the battery cover 30 plate and the roller brush cover 24 extremely simple, which helps to improve the installation efficiency, and on the other hand, ensures the stability and reliability of the battery cover 30 and the roller brush cover 24 after installation.

[0081] Optionally, in some embodiments, in order to further strengthen the connection stability between the battery cover 30 and the roller brush cover 24, the part overlapping between the battery cover 30 and the roller brush cover 24 can also be reinforced by fasteners such as screws and bolts.

[0082] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; under the idea of the present application, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other changes of different aspects of the present application as described above, which are not provided in details for the sake of simplicity; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
