Description

[Technical field]

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

[0002] The present disclosure relates to the field of cleaning appliances, and more particularly to cleaning brushes and smart cleaning appliances. [Background technology]

[0003] The cleaning brush is an important functional part of the cleaning device, and the end cap of the cleaning brush is used to receive wound material such as hair or thread that gets wound around the cleaning device during operation, and to prevent the wound material from stretching too much at the end of the cleaning brush and getting stuck on the output power end and bearing end of the motor.

[0004] The size of the end cap of the conventional cleaning brush is relatively small, the end of the shaft of the cleaning brush is exposed outside the end cap, and the end cap is located outside the cylindrical member that sleeves around the cleaning brush shaft telescopic cover, so that the wound material wound around the cylindrical member is easily wound from the end of the cylindrical member to the end of the shaft, but the winding position is relatively deep, and it is necessary to remove the end cap to take out the wound material from inside the cylindrical member, which is troublesome. In addition, the size of the end cap of the conventional cleaning brush is relatively small, and if the end cap is not attached while the cleaning brush is being attached, it is difficult to find, so it is necessary to install a corresponding mechanism to prevent the end cap from being attached.

It should be understood that the present disclosure may have various modifications in different embodiments, none of which departs from the scope of the present disclosure, and the description and accompanying drawings therein are only used for illustrative purposes in nature, and are not intended to limit the present disclosure.

It should also be understood that other specific arrangements of parts, structures, exemplary devices, systems and steps can be used, and modifications of structure and functionality can be made without departing from the scope of the present disclosure. And, although terms such as "on", "between", and "within" can be used in this specification to describe different exemplary features and elements of the present disclosure, these terms are used herein for convenience only, such as the orientation of the examples shown in the accompanying drawings. Nothing in this specification should be understood as requiring a specific three-dimensional orientation of a structure to fall within the scope of the present disclosure.

[0036] Referring to FIG. 1, it is a representative diagram showing the three-dimensional structure of the cleaning brush proposed in the present disclosure. In this exemplary embodiment, the cleaning brush proposed in the present disclosure is described as being applied to a smart cleaning robot. As can be easily understood by those skilled in the art, in order to apply the related design of the present disclosure to other types of cleaning equipment, multiple modifications, additions, substitutions, deletions or other changes can be made to the following specific embodiments, and these changes are within the scope of the principle of the cleaning brush proposed in the present disclosure.

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

[0038] As shown in FIG. 1 to FIG. 4, in one embodiment of the present disclosure, the axial rod 100 has two first ends 110 opposite along the axial direction, i.e., both ends of the axial rod 100 are the respective first ends 110. The tubular member 200 is sleeved coaxially around the axial rod 100, and the tubular member 200 has two second ends 210 opposite along the axial direction, i.e., both ends of the tubular member 200 are the respective second ends 210. A brush member is installed on the outer surface of the tubular member 200. Two end members 300 are respectively attached to the two first ends 110 of the axial rod 100. Each end member 300 has a stopper structure 310 that can prevent a winding such as hair or thread from excessively stretching away from the cleaning brush. And, the end member 300 and the first end 110 corresponding to the end member 300 each have a fitting structure 400 that fits with each other. In addition, the second end 210 of the tubular member 200 corresponding to the end member 300 covers at least a part of the end member 300, specifically, refer to the coverage area A shown in FIG. 4. With the above design, the present disclosure utilizes at least a part of the end member 300 being interposed between the shaft rod 100 and the corresponding end of the tubular member 200, avoiding the winding material wound on the tubular member 200 being directly wound on the shaft rod 100, and the winding material is mainly wound on the end member 300, and furthermore, the winding material is removed together with the removal of the end member 300, making cleaning more convenient. In addition, if the end member 300 is not installed during installation of the cleaning brush, the cleaning brush will obviously have missing parts, which will be easily found.

[0039] It should be noted that in the embodiments described herein, the end member 300 is installed on each of the two first ends 110 of the shaft rod 100. It should be understood that in some embodiments, the present disclosure provides that the end member 300 can be attached to only one first end 110 of the shaft rod 100. In other words, in various possible embodiments that meet the design concept of the present disclosure, the cleaning brush proposed in the present disclosure includes at least one end member 300, and the at least one end member 300 is attached to at least one first end 110 of the shaft rod 100.

[0040] As shown in Figures 2, 4 and 6, in one embodiment of the present disclosure, the second end 210 of the tubular member 200 corresponding to the end member 300 can cover the first end 110 to which the end member 300 is attached. In other words, the entire first end 110 to which the end member 300 is attached is located 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 rod 100 is smaller than the length of the tubular member 200. In some embodiments, the first end 110 to which the end member 300 is attached may protrude partially outside the coverage range of the corresponding second end 210, i.e., the first end 110 may protrude outside the coverage area A shown in Figure 4, as long as it is ensured that the second end 210 covers at least a part of the end member 300, not limited to this embodiment.

[0041] 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 210 corresponding to the end member 300 in the tubular member 200. In other words, the stopper structure 310 of the end member 300 may be located outside the coverage area A shown in FIG.

[0042] As shown in Figures 2, 4 and 6, in an 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 opened on the end face of the first end portion 110. The guide shaft 412 is connected to the end member 300, and the guide shaft 412 is used to be inserted into the guide hole 411. With the above design, the present disclosure can provide an axial guide function and a radial position limiting function for the mounting of the end member 300 and the shaft rod 100 by using the guide shaft 412 and the guide hole 411 that are inserted and fitted.

[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 rod 100, and the guide bush 420 can be sleeved around the first end 110. In addition, 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. Thus, the cleaning brush can restrict the relative rotation between the shaft rod 100 and the end member 300 due to the fit between the first position limiting structure and the second position limiting structure.

[0044] 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. In addition, the guide bush 420 may be spaced apart to surround the periphery of at least a portion of a segment 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 may include only the guide bush 420, or may realize the mounting and fixing of the end member 300 and the first end 110 of the shaft rod 100 by other structures.

[0045] As shown in FIG. 4, in one embodiment of the present disclosure, the ratio of the distance L1 between the stopper structure 310 corresponding to the same first end 110 and the end of the guide bush 420 away from the end member 300 along the axial direction of the shaft rod 100 to the length L0 of the shaft rod 100 may be greater than 5%, for example, 5%, 8%, 10%, 15%, etc. As a result, compared with the design of the end cap of the conventional cleaning brush having a relatively small size, the present disclosure has a design in which the guide bush 420 portion is interposed between the first end 110 and the second end 210, thereby giving the end member 300 a relatively large size (including the size of the guide bush 420), thereby increasing the space in which the wound material of the end member 300 is wound, and further preventing the wound material from being wound around the shaft rod 100. In other words, the present disclosure adopts a design related to the length of the above-mentioned related members, so that the length of the mating segment between the end member 300 and the shaft rod 100 is longer, the size is larger, and processing production is facilitated.

[0046] As shown in FIG. 6 and FIG. 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 consistent with the shape of the position limiting rib 432. Thus, in the process of the guide bush 420 being sleeved onto the first end 110 of the shaft rod 100, the position limiting rib 432 can be fitted into the position limiting groove 431 to provide a guide and stop function during the above-mentioned installation process. In some embodiments, the first position limiting structure may be the position limiting rib 432, and the second position limiting structure may be the position limiting groove 431. In other words, in various possible embodiments that meet the design concept of the present disclosure, one of the first position limiting structure and the second position limiting structure may be the position limiting rib 432, and the other may be the position limiting groove 431 whose shape is consistent with the position limiting rib 432. In addition, the first position limiting structure and the second position limiting structure may adopt other types of stopper fitting structures and are not limited thereto.

[0047] 6 and 8, in one embodiment of the present disclosure, the shape of the position limiting rib 432 and the position limiting groove 431 may be a matching spiral shape, so that during disassembly and assembly of the end member 300 and the axial rod 100, they can have a relative displacement along the axial direction and a relative rotation along the circumferential direction.

[0048] Based on the design that the position limiting rib 432 and the position limiting groove 431 are spiral-shaped, in one embodiment of the present disclosure, the spiral direction of the spiral-shaped position limiting rib 432 and the position limiting groove 431 may be opposite to the rotation direction of the axial rod 100. With the above design, when the axial rod 100 rotates in one rotation direction in the cleaning device, the spiral direction of the position limiting rib 432 and the position limiting groove 431 is opposite to the rotation direction, so that the position limiting rib 432 and the position limiting groove 431 can be further prevented from coming off, and the installation stability and reliability of the axial rod 100 and the end member 300 can be ensured.

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

[0050] 7 and 8, based on the design of the first mounting mark 421 on the guide bush 420, in one embodiment of the present disclosure, a deformation groove may be opened on the outer wall of the guide bush 420, which can play a role in preventing shrinkage deformation of the injection molded products such as the guide bush 420 and the end member 300. In addition, the deformation groove may adopt a special shape, such as a roughly triangular shape, an arrow shape, etc., which is used as the first mounting mark 421 to prevent shrinkage deformation and at the same time indicate the rotation direction when the end member 300 and the shaft rod 100 are mounted.

[0051] 4 and 6, in an embodiment of the present disclosure, when 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, pressing a part of the structure of the guide bush 420, etc. In addition, when the second position limiting structure is a position limiting groove 431, the position limiting groove 431 may be a recessed groove opened on the inner wall of the guide bush 420, or may be a through groove penetrating the guide bush 420.

[0052] In one embodiment of the present disclosure, the first end 110 may be provided with a plurality of first position limiting structures which may be evenly spaced apart along the circumferential direction of the axial rod 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 evenly spaced apart along the circumferential direction of the guide bush 420 .

[0054] To summarize the above, take the example of the first position limiting structure and the second position limiting structure being the position limiting groove 431 and the position limiting rib 432 respectively. When there are multiple position limiting grooves 431, the number of position limiting ribs 432 may be one or more, and the number of position limiting ribs 432 may be no more than the number of position limiting grooves 431, but may be less than the number of position limiting grooves 431.

[0055] 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 the at least one second mounting mark 422 may correspond to the position of the at least one second position limiting structure, thereby indicating the position of the at least one second position limiting structure. In some embodiments, when multiple 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 corresponds to any one of the second position limiting structures, or multiple second mounting marks 422 may be provided on the outer wall of the guide bush 420, and each of the multiple second mounting marks 422 corresponds to the multiple second position limiting structures.

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

[0057] As shown in FIG. 1 to FIG. 7, in one embodiment of the present disclosure, the two first ends 110 of the shaft rod 100 are both fitted with end members 300. A transmission structure 320 for transmitting torque is installed on one of the two end members 300. The other of the two end members 300 is used to install a bearing structure 500. The end member 300 on which the transmission structure 320 is installed is used to connect to a driving mechanism of a cleaning device through the transmission structure 320, and the end member 300 on which the bearing structure 500 is installed is used to rotate and connect to another structure (such as a main body) of the cleaning device through the bearing structure 500. Thus, when the end member 300 on which the transmission structure 320 is installed (i.e., the driving end cap) is installed, the driving end cap rotates around the guide hole 411, and the spiral position limiting groove 431 and the position limiting rib 432 cause the driving end cap to move along the axial direction while rotating, thereby completing the installation and removal of the entire end cap. Similarly, when the end member 300 (i.e., the bearing side end cap) for mounting the bearing structure 500 is mounted, the bearing side end cap may be mounted or removed with the same movement logic. At the same time, the spiral sense of the spiral position limiting rib 432 and the position limiting groove 431 is opposite to the rotation direction of the shaft 100 (i.e., the main brush operating direction), so that the spiral does not come off during operation. According to the above design, when the end member 300 is not mounted during the installation of the cleaning brush, the fitting structures (e.g., the stacked structure and the bearing structure 500) to which the two end members 300 are respectively mounted or installed are also not installed. Therefore, if the end member 300 is not installed properly, the main brush members (e.g., the shaft 100 and the tubular member 200) cannot be installed properly. This can achieve a more thorough function of preventing installation from being missed. In addition, when end members 300 are attached to both of the two first ends 110 of the axial rod 100, the same mounting structure 400 is adopted between the two first ends 110 of the axial rod 100 and the two end members 300, which makes it easier to prevent incorrect mounting during production, reduces the rate of processing errors, and helps improve the production rate.

[0058] As shown in Figures 1 and 2, based on the 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 with a regular polygonal cross section, and the axis of the columnar structure overlaps with the axis of both the end member 300 and the axial rod 100, so that the transmission structure 320 is used to engage with the output end of a driving mechanism, such as a 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 guide shaft 412 installed in this end member 300, which faces away from the shaft rod 100, protrudes from the end member 300 as an engaging segment 4121 that engages with the bearing structure 500, and the bearing structure 500 is removably installed on this engaging segment 4121 of the guide shaft 412.

[0060] 5 and 6, based on the design of the guide shaft 412 having the mating segment 4121, in one embodiment of the present disclosure, the mating segment 4121 of the guide shaft 412 may be provided with a positioning groove 4122 along the circumferential direction, for example, by designing the outer diameter of the mating segment 4121 to be smaller than that of other segments of the guide shaft 412, so that the positioning groove 4122 is formed in the mating segment 4121. In addition, the positioning groove 4122 is used to position and fit with the bearing structure 500 and prevent the bearing structure 500 from swinging.

[0061] As shown in FIG. 8, in one embodiment of the present disclosure, the end member 300 may be provided with a friction structure 330, such as but not limited to friction lines, friction protrusions, etc., which makes the end member 300 easier to screw in during installation.
