Description

[0001] This disclosure is a divisional application. The original application has the application number 202210022939.2, the application date is January 10, 2022, and the invention title is "Cleaning Brush and Intelligent Cleaning Device". Technical Field

[0002] This invention relates to the field of cleaning equipment technology, and more particularly to a cleaning brush and an intelligent cleaning device. Background Technology

[0003] The cleaning brush is an important functional component of cleaning equipment. The end cap of the cleaning brush is used to prevent hair or thread from getting tangled during the operation of the cleaning equipment, so as to prevent the tangled material from extending too far to the end of the cleaning brush and causing the motor output power end and bearing end to get tangled and stuck.

[0004] Existing cleaning brushes have small end caps, resulting in a significant portion of the brush shaft protruding beyond the end cap. Furthermore, the end cap is located outside the cylindrical component surrounding the brush shaft cap, causing any material wrapped around the cylindrical component to easily extend from its end to the end of the shaft, resulting in deep wrapping. This necessitates removing the end cap to remove the material from the cylindrical component, which is time-consuming and labor-intensive. Additionally, due to the small size of the existing end caps, it is difficult to detect if an end cap is missing during assembly, requiring a more robust anti-missing structure. Summary of the Invention

[0063] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different embodiments without departing from the scope of the present invention, and the description and drawings therein are for illustrative purposes only and not intended to limit the present invention.

[0064] In the following description of different exemplary embodiments of the invention, reference is made to the accompanying drawings, which form part of the invention, and in which different exemplary structures, systems, and steps that can implement various aspects of the invention are shown by way of example. It should be understood that other specific embodiments of the components, structures, exemplary devices, systems, and steps may be used, and structural and functional modifications may be made without departing from the scope of the invention. Furthermore, although the terms “above,” “between,” “within,” etc., may be used in this specification to describe different exemplary features and elements of the invention, these terms are used herein only for convenience, such as the orientation according to the examples shown in the drawings. Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of the invention.

[0065] See Figure 1 The illustration shows a three-dimensional structural diagram of the cleaning brush proposed in this invention. In this exemplary embodiment, the cleaning brush proposed in this invention is described using an application in an intelligent cleaning robot as an example. It will be readily understood by those skilled in the art that various modifications, additions, substitutions, deletions, or other changes may be made to the specific embodiments described below in order to apply the relevant designs of this invention to other types of cleaning equipment, and these changes are still within the scope of the principles of the cleaning brush proposed in this invention.

[0066] like Figure 1 As shown, in this embodiment, the cleaning brush proposed by the present invention mainly includes a shaft 100 (not shown in the figure), a cylindrical component 200, and two end components 300. See also... Figures 2 to 8 As shown, Figure 2 The diagram shows a representative three-dimensional exploded view of the cleaning brush; Figure 3 China representatively shows Figure 1 The main view; Figure 4 China representatively shows Figure 3 Axonometric sectional view; Figure 5 China representatively shows Figure 2 The main view; Figure 6 China representatively shows Figure 5 Axonometric sectional view; Figure 7 The diagram shows a representative three-dimensional structural schematic of the shaft 100 and the end member 300; Figure 8 China representatively shows Figure 7The diagram shows an enlarged view of the exploded structure, specifically illustrating the exploded state of an end member 300 and a first end 110 of the rotating rod. The structure, connection method, and functional relationship of the main components of the cleaning brush proposed in this invention will be described in detail below with reference to the above-mentioned figures.

[0067] like Figures 1 to 4 As shown, in one embodiment of the present invention, the shaft 100 has two first ends 110 opposite in the axial direction, that is, the two ends of the shaft 100 are respectively the first ends 110. The cylindrical member 200 is coaxially sleeved around the shaft 100, and the cylindrical member 200 has two second ends 210 opposite in the axial direction, that is, the two ends of the cylindrical member 200 are respectively the second ends 210. A brush is provided on the outer surface of the cylindrical member 200. Two end members 300 are respectively mounted on the two first ends 110 of the shaft 100. Each end member 300 has a blocking structure 310, which can prevent entangled objects such as hair or thread from extending excessively away from the cleaning brush. Furthermore, the end member 300 and its corresponding first end 110 each have mutually cooperating mounting structures 400. Based on this, the second end 210 of the cylindrical member 200 corresponding to the end member 300 covers at least a portion of the end member 300, as can be seen in the following description. Figure 4 The coverage area A is shown. Through the above design, the present invention utilizes at least a portion of the end member 300 to intervene between the corresponding ends of the shaft 100 and the cylindrical member 200, preventing the material wrapped around the cylindrical member 200 from directly wrapping around the shaft 100. Instead, the material is primarily wrapped around the end member 300, allowing it to be removed as the end member 300 is disassembled, making cleaning more convenient. Furthermore, during the assembly of the cleaning brush, when the end member 300 is not assembled, the cleaning brush is noticeably missing a part, making it easier to spot.

[0068] It should be noted that the various embodiments described in this specification are based on the example of both first ends 110 of the shaft 100 being provided with end members 300. It should be understood that in some embodiments, the present invention may also install an end member 300 on only one first end 110 of the shaft 100. In other words, in various possible embodiments conforming to the design concept of the present invention, the cleaning brush proposed by the present invention includes at least one end member 300, and at least one end member 300 is mounted on at least one first end 110 of the shaft 100.

[0069] like Figure 2 , Figure 4 and Figure 6As shown, in one embodiment of the present invention, the second end 210 of the cylindrical member 200 corresponding to the end member 300 can cover the first end 110 on which the end member 300 is mounted. In other words, the first end 110 on which the end member 300 is mounted is entirely within the coverage area of ​​the corresponding second end 210, that is, the first end 110 does not extend beyond the second end 210, i.e., the length of the shaft 100 is less than the length of the cylindrical member 200. In some embodiments, the first end 110 on which the end member 300 is mounted can also partially extend beyond the coverage area of ​​the corresponding second end 210, that is, the first end 110 can extend beyond... Figure 4 The coverage area shown is not limited to this embodiment; it is sufficient that the second end 210 covers at least a portion of the end member 300.

[0070] like Figures 1 to 6 As shown, in one embodiment of the present invention, the blocking structure 310 of the end member 300 may be located outside the second end 210 of the cylindrical member 200 corresponding to the end member 300. In other words, the blocking structure 310 of the end member 300 may be located outside the second end 210 of the cylindrical member 200 corresponding to the end member 300. Figure 4 Outside of the coverage area A shown.

[0071] like Figure 2 , Figure 4 and Figure 6 As shown, in one embodiment of the present invention, the mounting structure 400 may include a guide hole 411 and a guide shaft 412. Specifically, the guide hole 411 is coaxially formed on the end face of the first end portion 110. The guide shaft 412 is connected to the end member 300 and is inserted into the guide hole 411. Through the above design, the present invention can provide axial guiding and radial limiting functions during the installation of the end member 300 and the shaft 100 by utilizing the inserted guide shaft 412 and the guide hole 411.

[0072] like Figures 1 to 6 As shown, in one embodiment of the present invention, the mounting structure 400 may further include a guide sleeve 420. Specifically, the guide sleeve 420 is disposed at the end of the end member 300 facing the shaft 100, and the guide sleeve 420 can be sleeved around the periphery of the first end member 110. Based on this, a first limiting structure is provided on the side wall of the first end member 110, and a second limiting structure cooperating with the first limiting structure is provided on the inner wall of the guide sleeve 420. Accordingly, the cleaning brush can restrict relative rotation between the shaft 100 and the end member 300 through the cooperation of the first limiting structure and the second limiting structure.

[0073] In addition, such as Figure 2 , Figure 4 and Figure 6As shown, in one embodiment of the present invention, the mounting structure 400 may simultaneously include a guide hole 411, a guide shaft 412, and a guide sleeve 420. Furthermore, the guide sleeve 420 may be arranged at intervals around at least a portion of the periphery of the guide shaft 412. In some embodiments, the mounting structure 400 may also include only the guide hole 411 and the guide shaft 412, or only the guide sleeve 420, or other structures may be used to achieve the mounting and fixing of the end member 300 to the first end 110 of the shaft 100.

[0074] like Figure 4 As shown, in one embodiment of the present invention, along the axial direction of the shaft 100, the distance L1 between the blocking structure 310 and the end of the guide sleeve 420 furthest from the end member 300 corresponding to the same first end 110 can account for more than 5% of the length L0 of the shaft 100, for example, 5%, 8%, 10%, 15%, etc. Accordingly, compared with the smaller end cap design of existing cleaning brushes, the present invention, by partially intervening the guide sleeve 420 between the first end 110 and the second end 210, enables the end member 300 to have a larger size (including the size of the guide sleeve 420), thereby increasing the space for the end member 300 to be wound with the material, and further preventing the material from winding onto the shaft 100. In other words, the present invention, by adopting the above-mentioned design of the length relationship of the related components, extends the length of the mating portion between the end member 300 and the shaft 100, increases the size, and facilitates processing and production.

[0075] like Figure 6 and Figure 8 As shown, in one embodiment of the present invention, the first limiting structure can be a limiting groove 431, and the second limiting structure can be a limiting rib 432, with the limiting groove 431 and the limiting rib 432 matching in shape. Accordingly, when the guide sleeve 420 is fitted onto the first end 110 of the shaft 100, the limiting rib 432 and the limiting groove 431 cooperate with each other, providing guiding and limiting functions during the installation process. In some embodiments, the first limiting structure can also be a limiting rib 432, and the second limiting structure can also be a limiting groove 431. In other words, in various possible embodiments conforming to the design concept of the present invention, one of the first limiting structure and the second limiting structure can be a limiting rib 432, and the other can be a limiting groove 431 whose shape matches the limiting rib 432. Furthermore, the first limiting structure and the second limiting structure can also adopt other forms of limiting cooperation structures, and are not limited thereto.

[0076] like Figure 6 and Figure 8As shown, in one embodiment of the present invention, the limiting rib 432 and the limiting groove 431 can be matched spiral shapes. Accordingly, during the assembly and disassembly of the end member 300 and the shaft 100, there is relative displacement along the axial direction and relative rotation along the circumferential direction between the two.

[0077] Based on the helical shape of the limiting rib 432 and the limiting groove 431, in one embodiment of the present invention, the helical direction of the helical limiting rib 432 and the limiting groove 431 can be opposite to the rotation direction of the shaft 100. Through this design, when the shaft 100 rotates in a cleaning device in a rotational direction, since the helical direction of the limiting rib 432 and the limiting groove 431 is opposite to that rotational direction, it is possible to further prevent the limiting rib 432 from becoming detached from the limiting groove 431, thus ensuring the installation stability and reliability of the shaft 100 and the end member 300.

[0078] like Figure 7 and Figure 8 As shown, based on the spiral design of the limiting rib 432 and the limiting groove 431, in one embodiment of the present invention, the outer wall of the guide sleeve 420 may be provided with at least one first assembly mark 421, which can mark the rotation direction (i.e. the spiral direction of the limiting rib 432 and the limiting groove 431) when the end member 300 is assembled with the shaft 100.

[0079] like Figure 7 and Figure 8 As shown, based on the design of the guide sleeve 420 with a first assembly mark 421, in one embodiment of the present invention, the outer wall of the guide sleeve 420 may be provided with a deformation groove. This deformation groove can prevent shrinkage deformation of injection molded parts such as the guide sleeve 420 and the end member 300. Furthermore, the deformation groove can adopt a special shape, such as approximately triangular or arrow-shaped, to serve as the aforementioned first assembly mark 421, marking the rotation direction when the end member 300 is assembled with the shaft 100 while preventing shrinkage deformation.

[0080] like Figure 4 and Figure 6 As shown, in one embodiment of the present invention, when the second limiting structure is a limiting rib 432, the limiting rib 432 can be integrally formed on the inner wall of the guide sleeve 420. In some embodiments, the limiting rib 432 can also be formed on the inner wall of the guide sleeve 420 using other processes, such as welding, or forming by stamping a portion of the structure of the guide sleeve 420. Furthermore, when the second limiting structure is a limiting groove 431, the limiting groove 431 can be a groove formed on the inner wall of the guide sleeve 420, or a through groove penetrating the guide sleeve 420.

[0081] In one embodiment of the present invention, the first end 110 may be provided with a plurality of first limiting structures, which may be evenly arranged at intervals along the circumferential direction of the shaft 100.

[0082] In one embodiment of the present invention, the guide sleeve 420 may be provided with a plurality of second limiting structures, which are evenly arranged at intervals along the circumferential direction of the guide sleeve 420.

[0083] As mentioned above, taking the first limiting structure and the second limiting structure as limiting groove 431 and limiting rib 432 respectively as examples, when there are multiple limiting grooves 431, there can be one or more limiting ribs 432, and the number of limiting ribs 432 is no more than the number of limiting grooves 431, but can be less than the number of limiting grooves 431.

[0084] like Figure 5 and Figure 8 As shown, in one embodiment of the present invention, the outer wall of the guide sleeve 420 may be provided with at least one second assembly mark 422, and the position of the at least one second assembly mark 422 may correspond to the position of at least one second limiting structure, thereby marking the position of at least one second limiting structure. In some embodiments, when the inner wall of the guide sleeve 420 is provided with multiple second limiting structures, the outer wall of the guide sleeve 420 may be provided with only one second assembly mark 422, which corresponds to any one of the second limiting structures; or, the outer wall of the guide sleeve 420 may also be provided with multiple second assembly marks 422, which respectively correspond to multiple second limiting structures.

[0085] like Figures 1 to 6 As shown, in one embodiment of the present invention, the blocking structure 310 of the end member 300 can be a blocking ring, which can surround the outer periphery of the end member 300 and form a closed loop structure.

[0086] like Figures 1 to 7As shown, in one embodiment of the present invention, each of the two first ends 110 of the shaft 100 is equipped with an end member 300. One of the two end members 300 is provided with a transmission structure 320 for transmitting torque. The other end member 300 is used to mount a bearing structure 500. The end member 300 with the transmission structure 320 is connected to the drive mechanism of the cleaning equipment via the transmission structure 320, and the end member 300 with the bearing structure 500 is rotatably connected to other structures of the cleaning equipment (e.g., the machine body) via the bearing structure 500. Accordingly, when the end member 300 with the transmission structure 320 (i.e., the drive-side end cover) is installed, the drive-side end cover rotates around the guide hole 411, and due to the helical limiting groove 431 and the limiting rib 432, the drive-side end cover moves axially while rotating, thereby completing the assembly and disassembly of the end cover. Similarly, when the end member 300 (i.e., the bearing side end cover) used to install the bearing structure 500 is installed, the bearing side end cover can also be installed and removed according to the same motion logic. Meanwhile, since the spiral direction of the helical limiting rib 432 and limiting groove 431 is opposite to the rotation direction of the shaft 100 (i.e., the working direction of the main brush), the spiral will not loosen during operation. Through the above design, during the assembly of the cleaning brush, if the end member 300 is not assembled, the mating structures (e.g., the stacked structure and the bearing structure 500) installed or provided by each of the two end members 300 are also not provided. This prevents the main brush component (e.g., the shaft 100 and the cylindrical component 200) from being installed after the end member 300 is missing, thus achieving a more thorough anti-missing installation function. In addition, when both first ends 110 of the shaft 100 are equipped with end members 300, since the two first ends 110 of the shaft 100 and the two end members 300 adopt the same mounting structure 400, it is convenient to prevent mistakes during production, which helps to reduce the processing error rate and increase the production yield.

[0087] like Figure 1 and Figure 2 As shown, based on the design of a transmission structure 320 provided on an end member 300, in one embodiment of the present invention, the transmission structure 320 may include a columnar structure with a regular polygonal cross-section. The axis of the columnar structure coincides with the axis of the end member 300 and the shaft 100. Accordingly, the transmission structure 320 can be used to cooperate with the output end of a drive mechanism, such as the final output gear of a gearbox.

[0088] like Figures 2 to 6As shown, based on the design of a bearing structure 500 mounted on another end member 300, in one embodiment of the present invention, the end of the guide shaft 412 provided on the end member 300 that faces away from the shaft rod 100 extends out of the end member 300, thereby serving as a mating section 4121 that mates with the bearing structure 500. The bearing structure 500 is detachably mounted on the mating section 4121 of the guide shaft 412.

[0089] like Figure 5 and Figure 6 As shown, based on the design of the guide shaft 412 having a mating section 4121, in one embodiment of the present invention, the mating section 4121 of the guide shaft 412 can be provided with a positioning groove 4122 along the circumferential direction. For example, by designing the outer diameter of the mating section 4121 to be smaller than the outer diameter of other sections of the guide shaft 412, the mating section 4121 forms the positioning groove 4122. On this basis, the positioning groove 4122 is positioned and mated with the bearing structure 500 to prevent the bearing structure 500 from moving.

[0090] like Figure 8 As shown, in one embodiment of the present invention, the end member 300 may be provided with a friction structure 330, such as but not limited to friction patterns, friction protrusions, etc., thereby making the end member 300 easier to screw during assembly.

[0091] In one embodiment of the present invention, the cylindrical member 200 can be a flexible member or a rigid member. In addition, the brush can be disposed on the outer surface of the cylindrical member 200 by means of bonding, insertion or other methods. When the cylindrical member 200 is a flexible member, the brush can also be integrally formed with the cylindrical member 200. In some embodiments, the brush can also be other forms such as blades or bristles.

[0092] It should be noted that the cleaning brushes shown in the accompanying drawings and described in this specification are merely a few examples among many cleaning brushes capable of employing the principles of the invention. It should be clearly understood that the principles of the invention are by no means limited to any detail or component of the cleaning brushes shown in the accompanying drawings or described in this specification.

[0093] For example:
