Description

Technical Field

[0001] (Related Application) This application is proposed based on the Chinese patent application with application number 202210022939.2 and filed on January 10, 2022, claims the priority of this Chinese patent application, and all the contents of this Chinese patent application are incorporated into this application by reference.

[0002] This disclosure relates to the technical field of cleaning equipment, particularly to cleaning brushes and smart cleaning equipment.

Background Art

[0003] The cleaning brush is an important functional part of the cleaning equipment. The end cap of the cleaning brush receives winding objects such as hair or thread wound during the operation of the cleaning equipment, and is used to avoid the phenomenon that the winding object extends excessively to the end of the cleaning brush and winds around the output power end and bearing end of the motor to cause blockage.

[0004] [[ID=二十二]]The size of the end cap of the conventional cleaning brush is relatively small, the end of the shaft rod of the cleaning brush is long exposed outside the end cap, and the end cap is located outside the cylindrical member sleeved around the periphery of the cleaning brush shaft telescopic cover, so that the winding object wound around the cylindrical member is easy to wind from the end of the cylindrical member to the end of the shaft rod, the winding position is relatively deep, and it is necessary to remove the end cap to take out the winding object from the inside of the cylindrical member, which is time-consuming. In addition, the size of the end cap of the conventional cleaning brush is relatively small. When the end cap is not properly installed during the installation of the cleaning brush, it is difficult to detect, so it is necessary to install a corresponding anti-installation leakage structure.

It should be understood that this disclosure may have various variations in different embodiments, none of which deviate from the scope of this disclosure, and that the descriptions and accompanying drawings are for illustrative purposes only and do not limit this disclosure.

[0035] In the following descriptions of different exemplary embodiments of the Disclosure, reference is made to the accompanying drawings, which illustrate different exemplary structures, systems and steps that form part of the Disclosure and which can realize multiple aspects of the Disclosure in an exemplary manner. It should also be understood that modifications to the structure and functionality can be made using other specific arrangements of parts, structures, exemplary devices, systems and steps, and without departing from the scope of the Disclosure. Furthermore, while terms such as “above,” “between,” and “inside” may be used to describe different exemplary features and elements of the Disclosure, these terms are used solely for convenience herein, such as the example orientation shown in the accompanying drawings. It should not be understood that any content herein requires a specific three-dimensional orientation of a structure to address the scope of the Disclosure.

[0036] Referring to Figure 1, a representative schematic diagram of the three-dimensional structure of the cleaning brush proposed in this disclosure is shown. In this exemplary embodiment, the cleaning brush proposed in this disclosure is described as being applied to a smart cleaning robot. To the extent that it will be easily understood by those skilled in the art, several modifications, additions, substitutions, deletions or other changes have been made to the following specific embodiments in order to apply the relevant designs of this disclosure to other types of cleaning equipment, and these changes are within the scope of the principle of the cleaning brush proposed in this disclosure.

[0037] As shown in Figure 1, in this embodiment, the cleaning brush proposed in this disclosure mainly includes a shaft 100 (not shown), a cylindrical member 200, and two end members 300. Referring to Figures 2 to 8 in combination, Figure 2 shows a typical schematic exploded view of the cleaning brush, Figure 3 shows a typical front view of Figure 1, Figure 4 shows a typical cross-sectional view of the shaft side of Figure 3, Figure 5 shows a typical front view of Figure 2, Figure 6 shows a typical cross-sectional view of the shaft side of Figure 5, Figure 7 shows a typical schematic diagram of the three-dimensional structure of the shaft 100 and the end members 300, and Figure 8 shows a typical enlarged schematic diagram of the exploded state of some of the structures shown in Figure 7, specifically showing the exploded state of one end member 300 and one first end 110 of the pole. The structure, connection method, and functional relationship of each main component of the cleaning brush proposed in this disclosure will be described in detail below, referring to the above-mentioned attached drawings.

[0038] As shown in Figures 1 to 4, in one embodiment of the present disclosure, the shaft 100 has two opposite first ends 110 along the axial direction, i.e., both ends of the shaft 100 are the respective first ends 110. The cylindrical member 200 is coaxially sleeved around the shaft 100, and the cylindrical member 200 has two opposite second ends 210 along the axial direction, i.e., both ends of the cylindrical member 200 are the respective second ends 210. A brush member is installed on the outer surface of the cylindrical member 200. Two end members 300 are attached to the two first ends 110 of the shaft 100, respectively. Each end member 300 has a stopper structure 310 that can prevent a coiled material such as hair or thread from stretching excessively away from the cleaning brush. Each end member 300 and the corresponding first end 110 have a mounting structure 400 that fits together with each other. Furthermore, the second end 210 of the cylindrical member 200, which corresponds to the end member 300, covers at least a portion of the end member 300, specifically referring to coverage area A shown in Figure 4. With the above design, the present disclosure utilizes the fact that at least a portion of the end member 300 is interposed between the shaft 100 and the corresponding end of the cylindrical member 200, thereby avoiding the winding material wound around the cylindrical member 200 being directly wound around the shaft 100. The winding material is mainly wound around the end member 300, and furthermore, the winding material is removed when the end member 300 is removed, making cleaning more convenient. In addition, if the end member 300 is not installed while the cleaning brush is being installed, the cleaning brush will clearly have a missing part, making it easier to spot.

[0039] It should be noted that in each embodiment of this specification, the end members 300 are provided on both of the two first ends 110 of the shaft 100 as an example. It should be understood that in some embodiments, the disclosure may provide an end member 300 attached to only one of the first ends 110 of the shaft 100. In other words, in various possible embodiments that fit the design concept of the disclosure, the cleaning brush proposed herein includes at least one end member 300, and at least one end member 300 is attached to at least one first end 110 of the shaft 100.

[0040] As shown in Figures 2, 4, and 6, in one embodiment of the present disclosure, the second end 210 of the cylindrical member 200, which corresponds to the end member 300, can cover the first end 110 to which the end member 300 is attached. In other words, the entirety of the first end 110 to which the end member 300 is attached lies within the coverage range of the corresponding second end 210, i.e., the first end 110 does not protrude from 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 to which the end member 300 is attached may partially protrude from outside the coverage range of the corresponding second end 210, i.e., the first end 110 may protrude from outside the coverage area A shown in Figure 4, and is not limited to this embodiment, as long as it is ensured that the second end 210 covers at least a portion of the end member 300.

[0041] As shown in Figures 1 to 6, in one embodiment of the present disclosure, the stopper structure 310 of the end member 300 may be located outside the second end portion 210 of the cylindrical member 200 that corresponds to the end member 300. In other words, the stopper structure 310 of the end member 300 may be located outside the coverage region A shown in Figure 4.

[0042] As shown in Figures 2, 4, and 6, in one embodiment of the present disclosure, 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 used for insertion into the guide hole 411. With the above design, the present disclosure can provide axial guiding and radial position limiting functions for mounting the end member 300 and the shaft 100 by utilizing the insertable guide shaft 412 and the guide hole 411.

[0043] As shown in Figures 1 to 6, in one embodiment of the present disclosure, the mounting structure 400 may further include a guide bush 420. Specifically, the guide bush 420 is installed on the end of the end member 300 facing the shaft 100, and the guide bush 420 can be sleeved around the first end 110. Furthermore, a first position limiting structure is installed on the side wall of the first end 110, and a second position limiting structure that fits into the first position limiting structure is installed on the inner wall of the guide bush 420. This restricts the cleaning brush from relative rotation between the shaft 100 and the end member 300 through the fitting of the first and second position limiting structures.

[0044] Furthermore, as shown in Figures 2, 4, and 6, in one embodiment of the present disclosure, the mounting structure 400 may simultaneously include a guide hole 411, a guide shaft 412, and a guide bush 420. The guide bush 420 may be spaced apart to surround at least some segments of the guide shaft 412. In some embodiments, the mounting structure 400 may include only the guide hole 411 and the guide shaft 412, or only the guide bush 420, or other structures may be used to achieve mounting and fixing of the end member 300 and the first end 110 of the shaft rod 100.

[0045] As shown in Figure 4, in one embodiment of the present disclosure, the distance L1 between the stopper structure 310 corresponding to the same first end 110 and the end of the guide bush 420 that moves away from the end member 300, along the axial direction of the shaft 100, may be greater than 5% of the length L0 of the shaft 100, for example, 5%, 8%, 10%, or 15%. Compared to the design of conventional cleaning brushes with relatively small end caps, the present disclosure, by designing the guide bush 420 portion to be interposed between the first end 110 and the second end 210, allows the end member 300 to have a relatively large size (including the size of the guide bush 420), thereby increasing the space around which the winding material on the end member 300 is wound, and further preventing the winding material from being wound around the shaft 100. In other words, by adopting a design related to the length of the above-mentioned related members, the present disclosure increases the length of the fitting segment between the end member 300 and the shaft 100, increases the size, and facilitates processing and production.

[0046] As shown in Figures 6 and 8, in one embodiment of the present disclosure, the first position limiting structure may be a position limiting groove 431, and the second position limiting structure may be a position limiting rib 432, and the position limiting groove 431 is shaped to match the position limiting rib 432. This allows the position limiting rib 432 to engage with the position limiting groove 431 during the process of sleeved the guide bush 420 onto the first end 110 of the shaft rod 100, thereby providing a guide and stopper function during the installation process. In some embodiments, the first position limiting structure may be a position limiting rib 432, and the second position limiting structure may be a position limiting groove 431. In other words, in various possible embodiments that fit the design concept of the present disclosure, one of the first and second position limiting structures may be a position limiting rib 432, and the other may be a position limiting groove 431 whose shape matches that of the position limiting rib 432. Furthermore, the first and second position-limiting structures may employ other types of stopper fitting structures, and are not limited thereto.

[0047] As shown in Figures 6 and 8, in one embodiment of the present disclosure, the shapes of the position-limiting rib 432 and the position-limiting groove 431 may be a matching spiral shape. This allows both to undergo relative displacement along the axial direction and relative rotation along the circumferential direction during disassembly and assembly of the end member 300 and the shaft 100.

[0048] Based on the design in which the position-limiting rib 432 and position-limiting groove 431 have a spiral shape, in one embodiment of the present disclosure, the helical direction of the spiral-shaped position-limiting rib 432 and position-limiting groove 431 may be opposite to the rotational direction of the shaft 100. With the above design, when the shaft 100 rotates in one rotational direction within the cleaning equipment, the helical direction of the position-limiting rib 432 and position-limiting groove 431 is opposite to this rotational direction, thereby further preventing the position-limiting rib 432 and position-limiting groove 431 from coming off and ensuring the mounting stability and reliability of the shaft 100 and the end member 300.

[0049] As shown in Figures 7 and 8, based on a design in which the shape of the position-limiting rib 432 and the position-limiting groove 431 is spiral, in one embodiment of the present disclosure, at least one first mounting mark 421 may be provided on the outer wall of the guide bush 420, and this first mounting mark 421 can indicate the rotational direction when the end member 300 and the shaft rod 100 are mounted (i.e., the helical direction of the position-limiting rib 432 and the position-limiting groove 431).

[0050] As shown in Figures 7 and 8, based on a design in which a first mounting mark 421 is installed on the guide bush 420, in one embodiment of the present disclosure, a deformation groove may be provided on the outer wall of the guide bush 420, which can serve to prevent shrinkage deformation of injection molded products such as the guide bush 420 and the end member 300. Furthermore, the deformation groove may adopt a special shape, such as a roughly triangular shape or an arrow shape, and this will be used as the first mounting mark 421 to prevent shrinkage deformation and at the same time indicate the rotational direction when the end member 300 and the shaft rod 100 are mounted.

[0051] As shown in Figures 4 and 6, in one embodiment of the present disclosure, if the second position-limiting structure is a position-limiting rib 432, the position-limiting rib 432 may be installed on the inner wall of the guide bush 420 by an integral molding process. In some embodiments, the position-limiting rib 432 may be installed on the inner wall of the guide bush 420 by other processes, such as welding or forming from a part of the structure of the guide bush 420 by pressing. If the second position-limiting structure is a position-limiting groove 431, the position-limiting groove 431 may be a recessed groove opened in the inner wall of the guide bush 420, or it may be a through groove that penetrates the guide bush 420.

[0052] In one embodiment of the present disclosure, a plurality of first position limiting structures may be installed on the first end 110, which may be evenly spaced along the circumferential direction of the shaft 100.

[0053] In one embodiment of the present disclosure, the guide bush 420 may be provided with a plurality of second position limiting structures that are spaced evenly apart along the circumferential direction of the guide bush 420.

[0054] To summarize, taking the example that the first and second position-limiting structures are a position-limiting groove 431 and a position-limiting rib 432, respectively, if there are multiple position-limiting grooves 431, there may be one or more position-limiting ribs 432, and the number of position-limiting ribs 432 may not be greater than the number of position-limiting grooves 431, but may also be less than the number of position-limiting grooves 431.

[0055] As shown in Figures 5 and 8, in one embodiment of the present disclosure, at least one second mounting mark 422 may be provided on the outer wall of the guide bush 420, and the position of at least one second mounting mark 422 may correspond to the position of at least one second position limiting structure, thereby indicating the position of at least one second position limiting structure. In some embodiments, when a plurality of second position limiting structures are provided on the inner wall of the guide bush 420, only one second mounting mark 422 may be provided on the outer wall of the guide bush 420, and the one second mounting mark 422 may correspond to any of the second position limiting structures, or a plurality of second mounting marks 422 may be provided on the outer wall of the guide bush 420, and each of the plurality of second mounting marks 422 may correspond to a plurality of second position limiting structures.

[0056] As shown in Figures 1 to 6, in one embodiment of the present disclosure, the stopper structure 310 of the end member 300 may be a barrier ring that surrounds the periphery of the end member 300 and exhibits a closed-loop structure.

[0057] As shown in Figures 1 to 7, in one embodiment of the present disclosure, end members 300 are attached to both first ends 110 of the shaft 100. A transmission structure 320 for transmitting torque is installed on one of the two end members 300. The other end member 300 is used to attach a bearing structure 500. The end member 300 on which the transmission structure 320 is installed is used to connect to the drive mechanism of the cleaning equipment via the transmission structure 320, and the end member 300 on which the bearing structure 500 is installed is used to rotatably connect to other structures of the cleaning equipment (e.g., the main body) via the bearing structure 500. Thus, when the end member 300 on which the transmission structure 320 is installed (i.e., the drive-side end cap) is installed, the drive-side end cap rotates around the guide hole 411, and the spiral position-limiting groove 431 and position-limiting rib 432 cause the drive-side end cap to rotate and move axially, thereby completing the installation and removal of the entire end cap. Similarly, when an end member 300 (i.e., a bearing-side end cap) for mounting the bearing structure 500 is attached, the bearing-side end cap may be attached or removed using the same motion logic. At the same time, since the helical sense of the spiral position-limiting rib 432 and position-limiting groove 431 is in the opposite direction to the rotation direction of the shaft 100 (i.e., the main brush operating direction), the situation in which the helix comes loose during operation does not occur. With the above design, when the cleaning brush is installed, if the end member 300 is not installed, the fitting structure (e.g., the laminated structure and the bearing structure 500) to which the two end members 300 are attached or installed is also not installed. As a result, if the end member 300 is not attached, the main brush member (e.g., the shaft 100 and the cylindrical member 200) cannot be properly installed. This makes it possible to achieve a more thorough prevention of installation omissions. Furthermore, when end members 300 are attached to both first ends 110 of the shaft 100, the same mounting structure 400 is used between the two first ends 110 of the shaft 100 and the two end members 300, which helps to prevent incorrect installation during production, reduces the rate of processing errors, and improves the production yield.

[0058] As shown in Figures 1 and 2, based on a design in which the transmission structure 320 is installed on one end member 300, in one embodiment of the present disclosure, the transmission structure 320 may include a columnar structure having a regular polygonal cross-section, the axis of which the columnar structure coincides with the axis of both the end member 300 and the shaft 100, thereby the transmission structure 320 is used to engage with the output end of a drive mechanism, for example, the final stage output gear of a gearbox.

[0059] As shown in Figures 2 to 6, based on a design in which the bearing structure 500 is attached to another end member 300, in one embodiment of the present disclosure, one end of the shaft 100 facing away from the end member 300 of the guide shaft 412 installed on the end member 300 protrudes from the end member 300 and serves as a fitting segment 4121 that fits into the bearing structure 500, and the bearing structure 500 is detachably installed on this fitting segment 4121 of the guide shaft 412.

[0060] As shown in Figures 5 and 6, based on a design in which the guide shaft 412 has a fitting segment 4121, in one embodiment of the present disclosure, a positioning groove 4122 may be provided in the fitting segment 4121 of the guide shaft 412 along the circumferential direction. For example, the positioning groove 4122 is formed in the fitting segment 4121 by designing the outer diameter of the fitting segment 4121 to be smaller than that of the other segments of the guide shaft 412. The positioning groove 4122 is then used to position-fit with the bearing structure 500 and prevent the bearing structure 500 from oscillating.

[0061] As shown in Figure 8, in one embodiment of the present disclosure, a friction structure 330 may be installed on the end member 300, and is not limited to, for example, friction grooves or friction protrusions, thereby making it easier to screw in the end member 300 during installation.

[0062] In one embodiment of this disclosure, the cylindrical member 200 may be a flexible member or a rigid member. The brush member may be attached to the outer surface of the cylindrical member 200 by means of adhesive, insertion, etc. If the cylindrical member 200 is a flexible member, the brush member may be integrally molded with the cylindrical member 200. In some embodiments, the brush member may be of other forms such as blades or brushes.

[0063] The cleaning brushes shown in the accompanying drawings and described herein are merely some examples of the many cleaning brushes to which the principles of this disclosure can be employed. It should be clearly understood that the principles of this disclosure are not limited to any detail or component of the cleaning brushes shown in the accompanying drawings or described herein.

[0064] The following are some examples. In one embodiment of the present disclosure, a plurality of first position limiting structures are provided at the first end, which are evenly spaced and arranged along the circumferential direction of the shaft.
