For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0046] Then, it needs to be explained that in the description of the present application, the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise stated, the meaning of "multiple" is two or more.

[0048] As the background art shows, in the prior art, the rolling brush includes a shell, a brush body and a blade, the brush body is connected with the shell, and the brush body can rotate relative to the shell along the rotation axis to clean the cleaning surface. The blade is arranged on the shell, and the blade is used to cut the long fiber-like garbage such as hair to prevent the fiber-like garbage from winding around the brush body.

[0049] However, the blade on the existing rolling brush is exposed on the shell, and the blade has a risk of cutting and has a safety hazard.

[0050] Based on this, the rolling brush structure and the cleaning device provided by the present application, the rolling brush structure is provided by setting a rolling brush body, a driving piece, a support assembly and a cutting piece. The rolling brush body is used to contact the cleaning surface to realize the cleaning function. The driving piece is rotatably arranged in the rolling brush body, and the driving piece has a driving portion on the side. The support assembly is slidingly connected in the rolling brush body and abuts against the driving portion. The cutting piece is connected to the support assembly.

[0051] When the driving piece rotates, the driving portion periodically drives the support assembly to slide towards the inner wall of the rolling brush body to drive the cutting piece to extend out of the rolling brush body to realize the cutting function; or the driving portion drives the support assembly to slide away from the inner wall of the rolling brush body to drive the cutting piece to retract into the rolling brush body to reduce the time of the cutting piece exposed to the outside, reduce the possibility of accidental contact of the user to the cutting piece, and improve the safety.

[0052] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, of the embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0053] Reference Figures 1 to 4 As shown, in a first aspect, this application provides a roller brush structure, including: a roller brush body 100, a drive member 200, a support assembly 300 and a cutter 400, wherein the drive member 200 is rotatably disposed within the roller brush body 100, and the peripheral side of the drive member 200 has a drive portion 210.

[0054] The support component 300 is slidably connected within the roller brush body 100 and abuts against the drive unit 210.

[0055] Cutting component 400 is connected to support component 300.

[0056] The drive unit 210 is configured to periodically drive the support assembly 300 to slide toward or away from the inner wall of the brush body 100 when the drive member 200 rotates, so as to drive the cutter 400 to extend or retract from the brush body 100.

[0057] Understandably, in cleaning equipment, the roller brush body 100 can be used to contact the ground or other cleaning surfaces. The surface of the roller brush body 100 can be provided with different cleaning sections to adapt to different types of cleaning tasks, such as removing dust, dirt, or other impurities. The roller brush body 100 can also protect the internal components from damage by dust, moisture, or other external factors.

[0058] For example, the brush body 100 can be cylindrical or other shapes, and the embodiments of this application are subject to many limitations.

[0059] The driving component 200 rotates along its own axis, which can drive the movement of other components. In a specific implementation, the driving component 200 can be connected to an external power source so that the external power source provides power to the driving component 200 to drive its rotation.

[0060] By providing a drive unit 210 on the periphery of the drive member 200, when the drive member 200 rotates, the drive unit 210 can convert the rotational motion of the drive member 200 into the linear motion of the support assembly 300 and the cutting member 400.

[0061] The cutting member 400 is mounted on the support assembly 300, and is used to perform a cutting function. The support assembly 300 is slidingly connected to the roller brush body 100, and can support and guide the movement of the cutting member 400. The support assembly 300 transmits the movement of the driving portion 210 to the cutting member 400, so as to realize the extension and retraction function of the cutting member 400.

[0062] When the cutting member 400 does not need to perform the cutting function, it can be retracted into the roller brush body 100, thereby reducing the time of exposure of the cutting member 400 to the outside, and reducing the possibility of accidental contact of the cutting member 400 by a user or other objects, and improving the use safety of the roller brush structure.

[0063] Specifically, when the driving member 200 rotates in the +W direction shown by the arrow in FIG. 8, the support assembly 300 is periodically driven to slide towards the inner wall of the roller brush body 100 (i.e., in the +Y direction shown by the arrow in FIG. 8), so as to drive the cutting member 400 to extend out of the roller brush body 100, so as to realize the cutting function. Alternatively, the support assembly 300 is driven to slide away from the inner wall of the roller brush body 100 (i.e., in the -Y direction shown by the arrow in FIG. 8), so as to drive the cutting member 400 to retract into the roller brush body 100, thereby improving the safety. Figure 2 Figure 2 Specifically, since the support assembly 300 is in abutment with the driving portion 210, that is, the support assembly 300 is in abutment with the first driving segment 211. When the driving member 200 rotates in the +W direction shown by the arrow in FIG. 8, the first driving segment 211 sequentially contacts the support assembly 300 from the first end 2111 to the second end 2112. Since the first driving segment 211 is arc-shaped, and the distance between the second end 2112 and the rotation center of the driving member 200 is greater than the distance between the first end 2111 and the rotation center of the driving member 200, the distance between the support assembly 300 in abutment with the first driving segment 211 and the rotation center of the driving member 200 gradually increases, that is, the support assembly 300 moves towards the inner wall of the roller brush body 100 (i.e., in the +Y direction shown by the arrow in FIG. 8). Figure 2

[0064] In some embodiments, as shown in FIGS. 9 and 10, the driving portion 210 includes at least one first driving segment 211, the first driving segment 211 is arc-shaped, and the first driving segment 211 has a first end 2111 and a second end 2112. The distance between the second end 2112 and the rotation center of the driving member 200 is greater than the distance between the first end 2111 and the rotation center of the driving member 200. Figure 3 Figure 4 Specifically, since the support assembly 300 is in abutment with the driving portion 210, that is, the support assembly 300 is in abutment with the first driving segment 211. When the driving member 200 rotates in the +W direction shown by the arrow in FIG. 8, the first driving segment 211 sequentially contacts the support assembly 300 from the first end 2111 to the second end 2112. Since the first driving segment 211 is arc-shaped, and the distance between the second end 2112 and the rotation center of the driving member 200 is greater than the distance between the first end 2111 and the rotation center of the driving member 200, the distance between the support assembly 300 in abutment with the first driving segment 211 and the rotation center of the driving member 200 gradually increases, that is, the support assembly 300 moves towards the inner wall of the roller brush body 100 (i.e., in the +Y direction shown by the arrow in FIG. 8).

[0065] Figure 2 Figure 2 ​​​​​slides in the +Y direction (indicated by the middle arrow). Until the second end 2112 leaves the support assembly 300, the distance between the support assembly 300 abutting the first driving section 211 and the rotation center of the driving member 200 becomes smaller, that is, the support assembly 300 deviates from the inner wall of the rolling brush body 100 (i.e. Figure 2 slides in the -Y direction (indicated by the middle arrow). Since the cutting member 400 is arranged on the support assembly 300, the support assembly 300 can drive the cutting member 400 to extend out of or retract into the rolling brush body 100.

[0066] In some embodiments, referring to Figure 4 As shown, the driving part 210 further comprises at least one second driving section 212, the second driving section 212 is arc-shaped, and the distance between the middle of the second driving section 212 and the rotation center of the driving member 200 is greater than the distance between the two ends of the second driving section 212 and the rotation center of the driving member 200.

[0067] Specifically, when the second driving section 212 is sequentially contacted by the first end and the middle of the support assembly 300, the distance between the support assembly 300 abutting the second driving section 212 and the rotation center of the driving member 200 gradually becomes larger, that is, the support assembly 300 approaches the inner wall of the rolling brush body 100 (i.e. Figure 2 slides in the +Y direction (indicated by the middle arrow).

[0068] When the second driving section 212 is sequentially contacted by the middle and the second end of the support assembly 300, the distance between the support assembly 300 abutting the second driving section 212 and the rotation center of the driving member 200 gradually becomes smaller, that is, the support assembly 300 deviates from the inner wall of the rolling brush body 100 (i.e. Figure 2 slides in the -Y direction (indicated by the middle arrow).

[0069] In some embodiments, referring to Figures 3 to 5 As shown, the support assembly 300 comprises a support member 310 and a rolling member 320 rotationally connected to the support member 310, and the surface of the rolling member 320 is in contact with the surface of the driving part 210.

[0070] The support member 310 is slidingly connected to the rolling brush body 100, and the cutting member 400 is arranged on the support member 310.

[0071] It should be noted that the contact between the rolling member 320 and the surface of the driving part 210 can reduce the friction, reduce energy loss, and improve the efficiency of the system.

[0072] By arranging the rolling member 320, the support member 310 can move more stably under the action of the driving part 210, reducing the shaking or jamming phenomenon caused by uneven friction, which helps to improve the stability and accuracy of the movement of the cutting member 400.

[0073] In some embodiments, referring to Figure 3 and Figure 5 The support assembly 300 further includes a connecting piece 330 and an elastic piece 340, the connecting piece 330 connects the cutting piece 400 and the support piece 310.

[0074] The elastic piece 340 is sleeved on the connecting piece 330, one end of the elastic piece 340 abuts against the support piece 310, and the other end of the elastic piece 340 abuts against the roller brush body 100.

[0075] Specifically, when the driving part 210 is sequentially in contact with the rolling piece 320 from the first end 2111 to the second end 2112, the first driving section 211 drives the support piece 310 to slide along the +Y direction shown by the arrow in the middle through the rolling piece 320, and the elastic piece 340 is squeezed because the elastic piece 340 abuts against the support piece 310 and the roller brush body 100. Figure 2

[0076] Until the second end 2112 leaves the rolling piece 320, the rolling piece 320 loses the force of the first driving section 211, the elastic piece 340 gives the support piece 310 a force along the -Y direction shown by the arrow in the middle, and the support piece 310 slides along the -Y direction to make the support piece 310 and the rolling piece 320 return to the initial position. Because the connecting piece 330 connects the cutting piece 400 and the support piece 310, the support piece 310 drives the cutting piece 400 to return to the initial position synchronously through the connecting piece 330. Figure 2

[0077] Exemplarily, the connecting piece 330 can be connected with the cutting piece 400 and the support piece 310 by welding, bolt connection, plug-in connection, and clamping, respectively, and other connection modes can also be adopted, and the embodiments of the present application do not make too many limitations in this regard.

[0078] In some embodiments, referring to Figure 6 and Figure 7 The roller brush body 100 has at least one pair of guide pieces 110, the support piece 310 is located between the two guide pieces 110, and the support piece 310 is in sliding connection with the roller brush body 100 through the guide pieces 110.

[0079] It should be noted that the guide pieces 110 provide a clear sliding path for the support piece 310, ensuring that the support piece 310 moves along a predetermined direction, thereby helping to improve the operation precision of the cutting piece 400.

[0080] By limiting the movement direction of the support piece 310, unnecessary lateral movement or shaking can also be prevented, thereby improving the stability and reliability of the entire system.

[0081] In some embodiments, referring to Figure 7 ​​As shown, one of the guide 110 and the support 310 is provided with a sliding rail 111, and the other is provided with a sliding groove 311 matched with the sliding rail 111, and the sliding groove 311 is in sliding connection with the sliding rail 111.

[0082] It can be understood that the cooperation of the sliding rail 111 and the sliding groove 311 provides precise linear guidance, so that the support 310 can move smoothly along the extension direction of the guide 110.

[0083] In specific implementation, the sliding rail 111 and the sliding groove 311 can be provided as low-friction contact surfaces, which can effectively reduce the friction during movement, not only reducing wear, but also prolonging the service life of the guide 110 and the support 310.

[0084] In some embodiments, referring to Figures 1 to 3 As shown, the roller brush body 100 is provided with an access 120 for the cutting member 400 to extend out of or retract into the roller brush body 100.

[0085] Specifically, the access 120 allows the cutting member 400 to extend out of the roller brush body 100 when needed to perform cutting tasks, and to retract into the roller brush body 100 when not needed, thereby reducing the possibility of accidental contact of the cutting member 400 by the user, and improving the safety of the roller brush structure.

[0086] In some embodiments, referring to Figure 1 As shown, the roller brush body 100 is further provided with a protection member 130, and the protection member 130 is arranged around the periphery of the access 120.

[0087] It should be noted that by arranging the protection member 130, the dust, liquid or other impurities entering the interior of the roller brush body 100 through the access 120 can be reduced, thereby protecting the cleanliness and normal operation of the internal components.

[0088] Exemplarily, the protection member 130 can be made of silica gel or rubber material, which not only can provide good sealing performance, but also has good elasticity and buffering performance, and can provide buffering when the cutting member 400 extends out or retracts, thereby reducing damage caused by collision or vibration.

[0089] In some embodiments, referring to Figure 3 and Figure 5 As shown, the protection member 130 is provided with at least one abutting portion 131 on the side facing the elastic member 340, and the abutting portion 131 is used to abut against the other end of the elastic member 340.

[0090] It should be noted that by providing the abutting portion 131 on the protection piece 130, the other end of the elastic piece 340 abuts against the abutting portion 131, and since one end of the elastic piece 340 abuts against the support piece 310, the elastic piece 340 provides an elastic support between the support piece 310 and the abutting portion 131, so that the support piece 310 can move within a certain range.

[0091] In some embodiments, with reference to Figure 3 and Figure 5 As shown, the protection piece 130 is provided with at least one pair of limiting portions 132 on the side facing the cutting piece 400, and the pair of limiting portions 132 are symmetrically arranged on the opposite sides of the cutting piece 400.

[0092] Specifically, the symmetrically arranged limiting portions 132 can limit the transverse movement range of the cutting piece 400, prevent the cutting piece 400 from shaking or deviating, ensure that the cutting piece 400 maintains the correct position during operation, and improve the stability and reliability of the cutting piece 400.

[0093] By limiting the movement of the cutting piece 400, unnecessary friction and collision can be reduced, thereby reducing the possibility of wear and damage and prolonging the service life of the cutting piece 400.

[0094] In some embodiments, the driving portion 210 is further configured to drive the roller brush body 100 to rotate synchronously through the support assembly 300 when the driving piece 200 rotates reversely.

[0095] Specifically, when the driving piece 200 rotates forward (in the +W direction as indicated by the arrow in FIG. 13), the support assembly 300 is periodically driven to slide towards the inner wall of the roller brush body 100 (i.e., in the +Y direction as indicated by the arrow in FIG. 13) to make the cutting piece 400 extend out of the roller brush body 100 to realize the cutting function. Alternatively, the support assembly 300 is driven to slide away from the inner wall of the roller brush body 100 (i.e., in the -Y direction as indicated by the arrow in FIG. 13) to make the cutting piece 400 retract into the roller brush body 100 to improve safety. Figure 2 Figure 2 When the driving piece 200 rotates reversely (in the -W direction as indicated by the arrow in FIG. 13), the driving portion 210 drives the roller brush body 100 to rotate synchronously in the -W direction through the support assembly 300, so that the roller brush body 100 realizes the cleaning function. Thus, by providing the driving piece 200, both the cutting function of the cutting piece 400 and the cleaning function of the roller brush body 100 can be realized, which reduces the space and the cost. Figure 2 It should be noted that when the driving piece 200 rotates in the +W direction, the support assembly 300 is driven to slide towards the inner wall of the roller brush body 100 (i.e., in the +Y direction as indicated by the arrow in FIG. 13) to make the cutting piece 400 extend out of the roller brush body 100 to realize the cutting function. Alternatively, the support assembly 300 is driven to slide away from the inner wall of the roller brush body 100 (i.e., in the -Y direction as indicated by the arrow in FIG. 13) to make the cutting piece 400 retract into the roller brush body 100 to improve safety.

[0096] Figure 2 When the driving piece 200 rotates reversely (in the -W direction as indicated by the arrow in FIG. 13), the driving portion 210 drives the roller brush body 100 to rotate synchronously in the -W direction through the support assembly 300, so that the roller brush body 100 realizes the cleaning function. Thus, by providing the driving piece 200, both the cutting function of the cutting piece 400 and the cleaning function of the roller brush body 100 can be realized, which reduces the space and the cost.

[0097] It should be noted that when the driving piece 200 rotates in the +W direction, the support assembly 300 is driven to slide towards the inner wall of the roller brush body 100 (i.e., in the +Y direction as indicated by the arrow in FIG. 13) to make the cutting piece 400 extend out of the roller brush body 100 to realize the cutting function. Alternatively, the support assembly 300 is driven to slide away from the inner wall of the roller brush body 100 (i.e., in the -Y direction as indicated by the arrow in FIG. 13) to make the cutting piece 400 retract into the roller brush body 100 to improve safety. Figure 2 ​​When rotating in the W direction as indicated by the middle arrow, the second end 2112 of the first driving section 211 abuts against the support assembly 300, and the second end 2112 can drive the support assembly 300 to rotate synchronously. Since the support assembly 300 is in sliding connection with the roller brush body 100, the support assembly 300 can drive the roller brush body 100 to rotate together.

[0098] In some embodiments, referring to Figure 2 As shown, at least one of the inner wall of the roller brush body 100 and the driving member 200 is provided with at least one protrusion 140, and the other is provided with a groove 220 matched with the protrusion 140, and the protrusion 140 is located in the groove 220 to limit the driving member 200 on the roller brush body 100.

[0099] It should be noted that the cooperation of the protrusion 140 and the groove 220 improves the accurate positioning of the driving member 200 on the roller brush body 100, reduces the displacement or shaking of the driving member 200 during operation, and improves the stability of the driving member 200.

[0100] Exemplarily, referring to Figure 2 As shown, the protrusion 140 can be provided on the inner wall of the roller brush body 100, and the groove 220 matched with the protrusion 140 can be provided on the driving member 200; or the protrusion 140 can be provided on the driving member 200, and the groove 220 matched with the protrusion 140 can be provided on the inner wall of the roller brush body 100 (not shown in the drawings), and the embodiments of the present application do not make too many limitations.

[0101] In some embodiments, referring to Figure 2 As shown, the end of the driving member 200 is provided with a mounting portion 230, the mounting portion 230 extends out of the roller brush body 100, and the mounting portion 230 is used for connecting with an external power source.

[0102] It can be understood that the mounting portion 230 provides an interface, so that the external power source can be effectively connected to the driving member 200, so as to transmit power to the driving member 200, and realize the driving function of the cutting member 400 or the roller brush body 100.

[0103] In some embodiments, referring to Figure 2 As shown, the mounting portion 230 is a polygonal connecting hole.

[0104] It should be noted that the polygonal connecting hole provides a stable connection mode, reduces the risk of loosening or falling off due to vibration or load change during operation.

[0105] In some embodiments, referring to Figure 1 As shown, the roller brush body 100 is a brush or a rubber brush.

[0106] It should be noted that the fibers of the brush can penetrate into the gap to remove dust and debris. The brush is suitable for cleaning and cleaning various surfaces, especially carpets, fabrics or uneven surfaces.

[0107] The rubber brush can effectively adhere and remove dust, hair and fine particles on the surface. The rubber brush is usually used for cleaning smooth surfaces such as floors or glass.

The support assembly 300 is slidably connected in the rolling brush body 100, and abuts against the driving portion 210. The cutting member 400 is connected to the support assembly 300.

[0111] When the driving member 200 rotates, the driving portion 210 periodically drives the support assembly 300 to slide towards the inner wall of the rolling brush body 100, so as to drive the cutting member 400 to extend out of the rolling brush body 100, so as to realize the cutting function; or the driving portion 210 drives the support assembly 300 to slide away from the inner wall of the rolling brush body 100, so as to drive the cutting member 400 to retract into the rolling brush body 100, so as to reduce the time of the cutting member 400 exposed to the outside, reduce the possibility of accidental contact of the cutting member 400 by the user, and improve the safety.
