The general working principle of the rolling brush is that the rolling brush is in rotational contact with the cleaned surface to clean the surface by contact. However, whether the cleaning performance of the rolling brush can be further improved is of great significance to the cleaning device.

[0003] The cleaning device referred to in the present application generally refers to a household or small cleaning device. The small cleaning device requires small size and is sensitive to cost. Under these premises, it is very difficult to develop a rolling brush suitable for small cleaning devices.

[0004] The applicant has been engaged in the cleaning field for a long time. Through the applicant's unremitting research, the applicant proposes a rolling brush in the present application. The rolling brush can be heated to simulate the cleaning principle of wiping the surface with a hot cloth, which makes it easier to remove stains and improves cleaning efficiency and effect. The rolling brush is independently arranged and is not limited by an external power supply. That is, the rolling brush and the external power supply can be independent of each other. According to the present application, the rolling brush itself does not need to be powered. SUMMARY

[0005] The present application solves the technical problem of overcoming the defects of the prior art and proposes a rolling brush. The rolling brush can be heated to simulate the cleaning principle of wiping the surface with a hot cloth, which makes it easier to remove stains and improves cleaning efficiency and effect. The rolling brush is independently arranged and is not limited by an external power supply. That is, the rolling brush and the external power supply can be independent of each other. According to the present application, the rolling brush itself does not need to be powered. A cleaning device is also proposed.

[0006] Compared with the prior art, the present application proposes a rolling brush comprising two ends and a barrel between the two ends. A cleaning portion is arranged on the outer periphery of the barrel. The barrel is provided with an electric heating body. The electric heating body is connected with an input structure. The input structure is arranged in at least one of the two ends. The input structure is used to rotatably and detachably connect an external power supply to supply power to the electric heating body.

[0007] Compared with the prior art, the present application has the following advantages: the present application heats the rolling brush by the heating body, and proposes a new scheme for introducing electrical connection in the rolling brush structure, that is, the electrical heating body is connected with an input structure, the input structure is arranged at least one of the two ends, and the input structure is used to rotatably and detachably connect an external power supply to supply power to the electrical heating body. The rotatable and detachable connection means that, under the premise that the rolling brush can rotate freely by 360 degrees, the external power supply and the rolling brush are electrically connected in a detachable manner through the input structure, that is, the detachable structure satisfies the condition that the rolling brush can rotate freely by 360 degrees and the external power supply can continuously supply power. After such design, the rolling brush is independently arranged and is not limited by the external power supply, that is, the rolling brush and the external power supply are independent of each other. According to the present application, the rolling brush itself does not need a power supply, thereby achieving the purpose of the present application. If the cleaning device is taken as an example, after the foregoing design, the rolling brush and the cleaning device can be conveniently disassembled, the power supply in the cleaning device can conveniently supply power to the electrical heating body in the rolling brush, and the rolling brush can rotate freely by 360 degrees. The rolling brush after heating has a certain temperature because the cleaning part has been heated, so the cleaning part can simulate the cleaning principle of wiping the surface with a hot cloth when cleaning the surface, which can more easily remove stains and improve cleaning efficiency and effect. Therefore, the rolling brush of the present application has better cleaning performance.

DETAILED DESCRIPTION

[0036] The following description is presented to enable any person skilled in the art to practice the application as claimed. Stated examples are provided only as examples, and other examples can be employed without departing from the spirit and scope of the application. The basic principles defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions without departing from the spirit and scope of the application.

[0037] The application is further described in detail as follows:

[0038] To help understanding, the example of the set is the inner cylinder 4, and the specific structural form of the set can be changed and is not limited to the structural form of the inner cylinder 4.

[0039] It is worth noting that the following one end, the other end is only a relative description, not absolute limit, that is, does not constitute a limitation on the scope of protection of the invention.

[0040] Embodiment one, for the overall structure, the structure is characterized in that, can not have outer cylinder 3 and inner cylinder 4, when need to replace, electric heating body 2 with the brush together with the replacement.

[0041] The overall structure of the appearance can refer to Figure 1 As shown, the overall structure can be only one cylinder, the cylinder buried electric heating body 2 and / or cylinder set electric heating body 2 and / or cleaning part 1 set electric heating body 2, when removed, the brush through the first rotating support end and the first side 10 can be detachably connected, the second rotating support end and the second side 11 can be detachably connected the two detachable connection from the brush holder, installation is also through the first rotating support end and the first side 10 can be detachably connected, the second rotating support end and the second side 11 can be detachably connected the two detachable connection overall installation in the brush holder.

[0042] Input structure can be a variety of structures, such as can draw lessons from, for example Figure 3 , 4 , the first input structure shown in figure 5, also can draw lessons from, for example Figure 11 , 12 The second input structure shown in figure 3. Any suitable input structure for the application can be applied.

[0043] Embodiment two is a kind of split structure, the structure is characterized in that, including outer cylinder 3 and inner cylinder 4, when need to replace, need to remove the outer cylinder 3 and inner cylinder 4, then the outer cylinder 3 and inner cylinder 4 can be separated, inner cylinder 4 can be reused, the outer cylinder 3 is replaced, can refer to the specific Figure 1 To figure 6, such design can greatly reduce the cost of use, also can greatly reduce waste and environmental burden. The following in combination with inner cylinder 4 are more detailed description:

[0044] As shown in Figure 1 The brush includes two ends and the cylinder between the two ends, the cylinder includes outer cylinder 3 and inner cylinder 4 which can be axially connected and disassembled, the outer cylinder 3 is provided with cleaning part 1, Figure 1 Although the cleaning part 1 is not drawn, but not hinder understanding, if you want to understand the cleaning part 1, can be combined Figure 9 Understanding.

[0045] In this example, as shown in Figure 2 , 3As shown, the electric heating body 2 is arranged in the inner cylinder 4, and the inner cylinder 4 is arranged in a closed manner, which is not required to be absolutely closed, as long as a certain closed requirement is met, but if it can be absolutely closed, it is better. With the foregoing scheme, on the one hand, it is beneficial to protect the components and facilitate the reuse of the inner cylinder 4, and has a long service life, on the other hand, the structural reliability is better, and in long-term use, it can have better performance, and on the other hand, it is beneficial to improve safety, in addition, the inner cylinder 4 is arranged as an independent component, which is also convenient for production and assembly, and is beneficial to the stability of product quality.

[0046] As shown in the Figure 2 , the inner cylinder 4 and the outer cylinder 3 are provided with a guide structure for guiding the sleeve connection and disassembly of the inner cylinder 4 and the outer cylinder 3. This can effectively improve the accuracy of installation and facilitate user use.

[0047] The guide structure also serves as a circumferential transmission structure between the inner cylinder 4 and the outer cylinder 3. This design can effectively simplify the structure and facilitate control of the radial dimension.

[0048] As shown in the Figure 2 , the guide structure includes a guide groove 5 and a guide rib 6, and the guide groove 5 and the guide rib 6 are inserted and matched. This design is beneficial to the reliability of circumferential transmission and also helps to avoid the loosening of the inner cylinder 4 and the outer cylinder 3. In this example, the guide groove 5 and the guide rib 6 are arranged in multiple along the axial direction of the inner cylinder 4 and are uniformly distributed along the circumference.

[0049] As shown in the Figure 6 , one of the two ends is arranged as a first rotating support end, which serves as a disassembly end, and the other end is arranged as a second rotating support end. The first rotating support end is arranged at one end of the outer cylinder 3 and / or one end of the inner cylinder 4, and the second rotating support end is arranged at the other end of the outer cylinder 3 and / or the other end of the inner cylinder 4. One end of the outer cylinder 3 is arranged as an opening, and the other end of the inner cylinder 4 can be inserted into the outer cylinder 3 through the opening to realize the mutual sleeve connection of the inner cylinder 4 and the outer cylinder 3. For distinction, the opening is marked as a second opening 9. In this example, since the second circumferential portion 20 is supported by the sleeve connection of one end of the inner cylinder 4, and the other end of the outer cylinder 3 is only in surface contact, without radial support, it can be understood that the first rotating support end is arranged at one end of the inner cylinder 4, that is, the rotating support is provided by one end of the inner cylinder 4, and as shown in the Figure 1 , 6 , the second rotating support end is arranged at the other end of the outer cylinder 3, and Figure 6It can be seen that the other end of the inner cylinder 4 does not extend to the other end of the outer cylinder 3 all the time, but is shorter than the length of the outer cylinder 3. Although the example is designed in this way, it is not limited to this design. As mentioned above and / or described, the first rotating support end and the second rotating support end can have different structural combinations, that is, whether the two ends of the inner cylinder 4 and the outer cylinder 3 are used as rotating support ends can be arranged and combined mathematically, thereby obtaining a variety of combination structure schemes. For example, the other end of the inner cylinder 4 extends to the other end of the outer cylinder 3 all the time. The transmission connection end 39 is connected to the other end of the outer cylinder 3 and the other end of the inner cylinder 4. The other end of the outer cylinder 3 and the other end of the inner cylinder 4 jointly provide radial support. It can be understood that the second rotating support end is provided at the other end of the outer cylinder 3 and at the other end of the inner cylinder 4.

[0050] In order to better understand the features of the roll brush disassembly and replacement in the example, further description is made in combination with the setting of the roll brush holder. The roll brush is installed in the roll brush holder, that is, the first rotating support end and the second rotating support end are respectively detachably rotatably connected with the roll brush holder. The roll brush holder is provided with two opposite sides, namely the first side 10 and the second side 11. The first rotating support end is detachably connected with the first side 10, and the second rotating support end is detachably connected with the second side 11. The roll brush can be integrally detachably connected with the roll brush holder through the two detachable connections mentioned above.

[0051] In the example, the disassembly structure of the outer cylinder 3 can be that the inner cylinder 4 and the outer cylinder 3 are detachably sleeved with each other. When disassembled, after the roll brush is integrally detached from the roll brush holder, the inner cylinder 4 and the outer cylinder 3 are disassembled and separated from each other along the axial direction by using the sleeving structure. When assembled, the inner cylinder 4 and the outer cylinder 3 can be first axially sleeved, then the transmission connection end 39 of the outer cylinder 3 is connected with the rotating output end, and the connection is used as a fulcrum. Then one end of the inner cylinder 4 is connected with the first side 10. Thus, the disassembly and replacement purposes are achieved.

[0052] In the example, in order to realize the input structure for rotatably connecting the external power supply to supply power to the electric heating body 2, the external power supply can be selected to be connected with any one of the two ends of the roll brush. The specific structure can have different forms and can be selected. The present application mainly takes the following structure as an example: Figure 14 、 15 、20、 22, the second side 11 is provided with a first contact piece, the other end of the inner cylinder 4 is provided with a second contact piece, the second contact piece is electrically connected with the heating body, the second contact piece rotates with the inner cylinder 4, and the second contact piece is dynamically electrically connected with the first contact piece to supply power to the heating body under the rotating motion; the second kind, referring to Figure 6The first side 10 is provided with a third contact piece, and one end of the inner cylinder 4 is provided with a fourth contact piece. The fourth contact piece is electrically connected to the heating element. The fourth contact piece rotates together with the inner cylinder 4. The fourth contact piece is dynamically electrically connected to the third contact piece to realize the power supply to the heating element during rotation.

[0053] Regarding the specific rotational configuration at the input structure end, the following structure can be adopted: The first side 10 has a second rotating engagement portion 17 protruding towards the second side 11. This second rotating engagement portion 17 is sleeved and rotatably engaged with one end of the inner cylinder 4 and / or one end of the outer cylinder 3. In this example, as... Figure 6 As shown, the second rotating fitting part 17 is sleeved and rotated with one end of the inner cylinder 4. This structure is simple and the rotating fit is reliable and stable.

[0054] like Figure 6 As shown, a second input end is provided at one end of the inner cylinder 4. The second input end includes a second shaft 19 and a second circumferential portion 20. A second annular gap 21 is formed between the second shaft 19 and the second circumferential portion 20. The second annular gap 21 is sleeved and rotatably engaged with the second rotating fitting portion 17. This design results in a compact structure, which helps to reduce the structural volume.

[0055] like Figure 3 , 4 As shown in Figure 6, a second electrical connection terminal serving as an electrical connection structure is provided in the circumferential gap between the second shaft 19 and the second rotating mating part 17. The second electrical connection terminal includes a second rotatable part and a second fixed part. The second rotatable part is connected to the second input end and can rotate together with the inner cylinder 4. The second fixed part is connected to the second rotating mating part 17. This design results in a compact structure, which helps to reduce the structural volume and also promotes stable and reliable electrical connection.

[0056] like Figure 3 , 6 As shown, the second input end also includes a second end portion 18, which is used to close one end of the inner cylinder 4. In this way, while achieving a sealing purpose, the structure is simple and compact, which helps to reduce the axial volume of the structure.

[0057] like Figure 3 , 6 As shown, the second rotatable part is integrally formed with the second end 18 of the second input terminal, for example, by injection molding. The second rotatable part serves as an injection-molded metal insert, integrally molded with the second input terminal. This design offers significant advantages, such as achieving electrical connection while ensuring a sealed design, which helps guarantee the performance and safety of the electrical connection. Furthermore, the structure is more compact, and manufacturing is easier.

[0058] The electrical connection structure between the second rotatable part and the second fixed part adopts an electrical connection structure which can be axially sleeved and matched with the second annular gap 21 and the second rotation matching part 17 to complete the electrical connection matching. Since there is mechanical structure connection, electrical connection and continuous electrical connection in the rotating state, the foregoing design is relatively ingenious, which greatly facilitates the production and assembly and solves the foregoing assembly difficulty while ensuring the performance.

[0059] As known from the foregoing, the electrical connection structure includes a fixed part and a rotatable part. Specifically, in the example, the fixed part includes a positive electrode conductive part and a negative electrode conductive part which are sleeved around the second shaft 19, as shown in Figure 4 The positive electrode conductive part and the negative electrode conductive part are both connected with the second rotation matching part 17, and the rotatable part includes a positive electrode contact piece and a negative electrode contact piece, as shown in Figure 3 、 6 The positive electrode contact piece and the negative electrode contact piece are both connected with the second input end, and in the example, the positive electrode contact piece and the negative electrode contact piece are integrally provided with the second end part 18 of the second input end. The positive electrode contact piece is electrically connected with the positive electrode conductive part, and the negative electrode contact piece is electrically connected with the negative electrode conductive part. Such structure is simple and reliable, facilitates the production and assembly, and is reliable and stable in connection.

[0060] The contact connection between the positive electrode contact piece and the positive electrode conductive part and the contact connection between the negative electrode contact piece and the negative electrode conductive part can be completed by axially sleeving and matching the corresponding annular gap with the corresponding rotation matching part. Since there is mechanical structure connection, electrical connection and continuous electrical connection in the rotating state, the foregoing design is relatively ingenious, which facilitates the mechanical structure connection and also facilitates the electrical connection, greatly facilitates the production and assembly and solves the foregoing assembly difficulty.

[0061] In the example, as shown in Figure 3 、 6 The positive electrode conductive part and the negative electrode conductive part are both provided with an axial contact conductive part, i.e., a positive electrode axial contact conductive part 22 and a negative electrode axial contact conductive part 23, and the positive electrode contact piece and the negative electrode contact piece both adopt an annular contact piece, i.e., a positive electrode annular contact piece 24 and a negative electrode annular contact piece 25. The annular side surface of the annular contact piece is used for axially abutting and electrically connecting with the axial contact conductive part. Such design has certain advantages, such as simple and compact structure, stable and reliable connection, and convenient production and manufacturing.

[0062] In order to better contact, in the example, as shown in Figure 6 The annular side of the annular contact piece and the axial abutting and electrical connection with the axial contact conductive part both adopt elastic connection, such as the positive electrode axial contact conductive part 22 and the negative electrode axial contact conductive part 23 which are both provided with a spring 50.

[0063] The electric connection structure can also be other structures, such as the positive electrode conductive part adopts a positive electrode conductive ring 26, the negative electrode conductive part adopts a negative electrode conductive ring 27, and an axial offset part is provided between the positive electrode conductive ring 26 and the negative electrode conductive ring 27. The positive electrode contact of the positive electrode tab is arranged in the positive electrode conductive ring 26 and is electrically connected to the inner surface of the positive electrode conductive ring 26. The negative electrode contact of the negative electrode tab is arranged in the negative electrode conductive ring 27 and is electrically connected to the inner surface of the negative electrode conductive ring 27. This structure has its own advantages, such as high structural strength, more reliable electrical connection, and can withstand large loads. In the foregoing structure, in order to facilitate electrical connection, the positive electrode conductive ring 26 is provided with a positive electrode lead-out tab 28, and the negative electrode conductive ring 27 is provided with a negative electrode lead-out tab 29, thereby further simplifying the wiring operation in production and assembly, and thereby facilitating improvement of production efficiency.

[0064] In this example, the contact connection between the positive electrode tab and the positive electrode conductive part, and the contact connection between the negative electrode tab and the negative electrode conductive part all adopt a carbon brush structure, that is, the contact adopts a carbon brush positive electrode 35 and a carbon brush negative electrode 36. This is low in cost, facilitates axial disassembly, and in addition, the connection is stable and reliable.

[0065] In order to prevent the outer cylinder 3 and the inner cylinder 4 from loosening after being connected, an elastic abutting structure can be provided between the outer cylinder 3 and the inner cylinder 4. The elastic abutting structure is used to elastically abut and connect the outer cylinder 3 and the inner cylinder 4 after the roller brush is connected to the roller brush holder. With the elastic abutting structure, the outer cylinder 3 and the inner cylinder 4 can be automatically elastically separated when disassembled, that is, automatically loosened, thereby facilitating the user to disassemble the outer cylinder 3 and the inner cylinder 4.

[0066] In this example, the second side 11 is provided with a driving structure, and the other end of the outer cylinder 3 is provided with a transmission connection end 39. The rotating output end of the driving structure is detachably connected to the transmission connection end 39. The rotating structure at one end of the inner cylinder 4 can be referred to as follows: after the roller brush holder is connected, the second rotating fitting part 17 is fixedly arranged, the second rotating fitting part 17 is mounted with a second bearing 42, the second bearing 42 rotatably supports a rotating connection shaft 40, the rotating connection shaft 40 is connected to a second shaft 19, and the second shaft 19 rotates together with the inner cylinder 4, that is, rotates together with the roller brush. When the roller brush rotates, it is rotatably supported by the second bearing 42, thereby realizing the rotating structure at one end of the inner cylinder 4, that is, the rotating structure at one end of the roller brush.

[0067] The cleaning part 1 adopts a wettable cleaning part 1. In this way, better cleaning ability can be obtained.

[0068] The cleaning part 1 is provided with a wetting member around the periphery, which is used to deliver cleaning liquid to the cleaning part 1. In this way, in cooperation with heating, better automatic cleaning can be realized.

[0069] The third embodiment is also a split structure, but the third embodiment has more advantages than the second embodiment. In addition to being reusable, the inner cylinder 4 is configured to remain on the roller brush holder when the outer cylinder 3 is removed. Specifically, after the detachable connection structure between the first rotating support end and the first side 10 is disengaged, the outer cylinder 3 can be removed and replaced along the axial direction, which is very convenient.

[0070] The third embodiment is described below in combination with the inner cylinder 4, and can also be understood in combination with the second embodiment.

[0071] As shown in Figure 9 , 11 , the roller brush includes two ends and a cylinder body between the two ends. The cylinder body includes an outer cylinder 3 and an inner cylinder 4 that can be axially coupled and detached. The outer cylinder 3 is provided with a cleaning part 1 on the outer periphery.

[0072] In this example, as shown in Figure 11 , 16 , the electric heating element 2 is arranged in the inner cylinder 4, and the inner cylinder 4 is provided in a closed manner. This closed arrangement does not require absolute closure, but only needs to meet certain closure requirements. However, if absolute closure can be achieved, it is even better. The above-mentioned scheme is beneficial to the protection of various components and the reuse of the inner cylinder 4, has a long service life, and has better structural reliability and performance in long-term use. In addition, the inner cylinder 4 is arranged as a separate component, which is convenient for production and assembly and is beneficial to the stability of product quality.

[0073] As shown in Figure 16 , 19 , a circumferential transmission structure is arranged between the inner cylinder 4 and the outer cylinder 3. The circumferential transmission structure is used to transmit rotation between the inner cylinder 4 and the outer cylinder 3 through the circumferential transmission structure while the driving structure drives the rotation of the inner cylinder 4 and / or the outer cylinder 3. This design can effectively simplify the structure and facilitate the control of the radial dimension.

[0074] The circumferential transmission structure also serves as a guide structure for the axial coupling between the inner cylinder 4 and the outer cylinder 3. The guide structure is used for guiding the coupling and disassembly of the inner cylinder 4 and the outer cylinder 3. This can effectively improve the accuracy of installation and facilitate user use.

[0075] The guide structure includes a guide groove 5 and a guide rib 6, and the guide groove 5 and the guide rib 6 are inserted and matched. This design is beneficial to the reliability of circumferential transmission and helps to avoid the loosening of the inner cylinder 4 and the outer cylinder 3. In this example, the guide groove 5 and the guide rib 6 are arranged in multiple along the axial direction of the inner cylinder 4 and are uniformly distributed along the circumference.

[0076] One of the two ends of the rolling brush of the third embodiment is provided as a first rotating support end, which is used as a disassembly end, and the other end is provided as a second rotating support end. The first rotating support end is arranged at one end of the outer cylinder 3 and / or one end of the inner cylinder 4, and the second rotating support end is arranged at the other end of the outer cylinder 3 and / or the other end of the inner cylinder 4. The other end of the outer cylinder 3 is provided with an opening, through which the outer cylinder 3 can be disassembled from the inner cylinder 4 through one end of the inner cylinder 4. In this example, the first rotating support end is arranged at one end of the outer cylinder 3, and the second rotating support end is arranged at the other end of the inner cylinder 4, which is beneficial to the simple and compact structure and is more conducive to achieving the design purpose of disassembling only the outer cylinder 3. Of course, other structures can also be used, such as and / or as described. For distinction, the opening is referred to as the first opening 8.

[0077] In order to better understand the disassembly and replacement features of the rolling brush in this example, further description is made in combination with the arrangement of the rolling brush holder. The rolling brush is installed in the rolling brush holder, that is, the rolling brush holder is provided with two opposite sides, namely a first side 10 and a second side 11. The other end of the inner cylinder 4 is connected with the second side 11, and when the outer cylinder 3 is connected with the inner cylinder 4 through the first opening 8 and the one end of the inner cylinder 4, the first rotating support end is detachably connected with the first side 10. Such a structure design is beneficial to greatly facilitating the disassembly of the outer cylinder 3, and is simple and compact in structure.

[0078] In this example, the disassembly structure of the outer cylinder 3 can be that a detachable connection structure is arranged between the first rotating support end and the first side 10. When disassembling, the other end of the inner cylinder 4 remains connected with the second side 11, and the outer cylinder 3 is disassembled along the direction from the second side 11 to the first side 10 after the detachable connection structure is released. When installing, the outer cylinder 3 can be inserted into the inner cylinder 4 through the first opening 8 and axially connected, and after being connected in place, the first rotating support end is connected with the first side 10 by using the detachable connection structure. Thus, the disassembly and replacement purposes are achieved.

[0079] In this example, in order to realize the input structure for rotating and detachably connecting the external power supply to supply power to the electric heating body 2, the external power supply can be selected to be connected with any one of the two ends of the rolling brush. The specific structure can have different forms and can be selected. The present application mainly takes the following structure as an example: Figure 14 、 15 、20、 22, the second side 11 is provided with a first contact piece, the other end of the inner cylinder 4 is provided with a second contact piece, the second contact piece is electrically connected with the heating body, the second contact piece rotates with the inner cylinder 4, and the second contact piece is dynamically electrically connected with the first contact piece to supply power to the heating body under the rotating motion; the second kind, referring to Figure 6The first side 10 is provided with a third contact, and one end of the inner cylinder 4 is provided with a fourth contact, the fourth contact is electrically connected with the heating body, the fourth contact rotates with the inner cylinder 4, and the fourth contact is dynamically electrically connected with the third contact to realize power supply for the heating body under rotating motion. In this example, the first type is adopted, so that the structure can be significantly simplified, and the safety is also very high. Because the user mainly operates at the first rotating support end when replacing the outer cylinder 3, according to the first design, the first rotating support end does not have any electrical connection structure, so the safety can be significantly improved. In addition, by adopting the first type and combining the characteristics that the inner cylinder 4 of this example remains connected, the electrical connection structure is also kept stable and protected, so the performance can be guaranteed, which is beneficial to prolong the service life and reliability.

[0080] At this end where the input structure is located, how to rotate is set as follows: the second side 11 is provided with a first rotating matching part 12 protruding towards the first side 10, the first rotating matching part 12 is sleeved and rotatingly matched with the other end of the inner cylinder 4 and / or the other end of the outer cylinder 3. In this example, as shown in Figure 11 、 12 , the first rotating matching part 12 is sleeved and rotatingly matched with the other end of the inner cylinder 4. In this way, the structure is simple, and the rotating matching is reliable and stable.

[0081] As shown in Figure 11 、 12 , the other end of the inner cylinder 4 is provided with a first input end, the first input end includes a first shaft 14 and a first peripheral part 15, a first annular interval 16 is formed between the first shaft 14 and the first peripheral part 15, and the first annular interval 16 is sleeved and rotatingly matched with the first rotating matching part 12. In this way, the structure is compact, which is beneficial to reduce the structure volume.

[0082] As shown in Figure 12 、 22 , a sealing ring 43 is arranged in the interval between the first peripheral part 15 and the first rotating matching part 12, the sealing ring 43 adopts an oil seal, on one hand, the oil seal stores oil inside, which is beneficial to rotating lubrication, thereby being beneficial to rotating connection, and on the other hand, the oil seal can isolate external dirt.

[0083] As shown in Figure 12 、 20 , a first electrical connection terminal used as an electrical connection structure is arranged in the circumferential interval between the first shaft 14 and the first rotating matching part 12, the first electrical connection terminal includes a first rotatable part and a first fixed part, the first rotatable part is connected with the first input end and can rotate with the inner cylinder 4, and the first fixed part is connected with the first rotating matching part 12. In this way, the structure is compact, which is beneficial to reduce the structure volume, and is also beneficial to stable and reliable electrical connection.

[0084] AsFigure 12 、 15 , 16, 17, the first input end further comprises a first end portion 13, the first end portion 13 is used to close the other end of the inner cylinder 4. In this way, the sealing purpose is achieved while the structure is simple and compact, which is conducive to reducing the axial volume of the structure.

[0085] As shown in Figure 15 、 20 , 22, the electrical connection structure between the first rotatable part and the first fixed part adopts an electrical connection structure that can be axially sleeved and matched with the first annular gap 16 and the first rotating matching part 12 to complete the electrical connection matching. Since there is both mechanical structure connection and electrical connection, and the electrical connection needs to be continuously connected in the rotating state, the foregoing design is relatively ingenious, which greatly facilitates production and assembly while ensuring performance, and solves the aforementioned assembly difficulties.

[0086] As known from the foregoing, the electrical connection structure includes a fixed part and a rotatable part. For example, in this example, the fixed part includes a positive electrode conductive part and a negative electrode conductive part that are sleeved around the first shaft 14, as shown in Figure 14 , 16, the positive electrode conductive part and the negative electrode conductive part are connected with the first rotating matching part 12, and the rotatable part includes a positive electrode contact piece and a negative electrode contact piece, as shown in Figure 15 、 20 , 22, the positive electrode contact piece and the negative electrode contact piece are connected with the first input end. In this example, the positive electrode contact piece and the negative electrode contact piece are mounted on the first shaft 14 of the first input end and located in the circumferential direction of the first shaft 14. The positive electrode contact piece is electrically connected with the positive electrode conductive part, and the negative electrode contact piece is electrically connected with the negative electrode conductive part. In this way, the structure is simple and reliable, facilitates production and assembly, and the connection is reliable and stable.

[0087] The contact connection between the positive electrode contact piece and the positive electrode conductive part, and the contact connection between the negative electrode contact piece and the negative electrode conductive part can be completed by axially sleeving and matching the corresponding annular gap with the corresponding rotating matching part to complete the electrical connection matching. Since there is both mechanical structure connection and electrical connection, and the electrical connection needs to be continuously connected in the rotating state, the foregoing design is relatively ingenious, which facilitates mechanical structure connection and also facilitates electrical connection, greatly facilitates production and assembly, and solves the aforementioned assembly difficulties.

[0088] In this example, the structure is the first type. Specifically, the positive electrode conductive part adopts a positive electrode conductive ring 26, the negative electrode conductive part adopts a negative electrode conductive ring 27, an axially offset portion is provided between the positive electrode conductive ring 26 and the negative electrode conductive ring 27, the positive electrode contact of the positive electrode contact piece is arranged in the positive electrode conductive ring 26, and the positive electrode contact is electrically connected with the inner surface of the positive electrode conductive ring 26. The negative electrode contact of the negative electrode contact piece is arranged in the negative electrode conductive ring 27, and the negative electrode contact is electrically connected with the inner surface of the negative electrode conductive ring 27. This structure has its own advantages, such as high structural strength, more reliable electrical connection, and the ability to withstand large loads.

[0089] In this case, as shown in Figure 25 , the brush side connecting support 48 is provided with the positive conductive ring 26 and the negative conductive ring 27. This structure is compact, stable and reliable.

[0090] In addition, the positive conductive ring 26 and the negative conductive ring 27 are integrally injection molded with the support 48, and the injection material between the positive conductive ring 26 and the negative conductive ring 27 serves as the insulation separation part 34 of the positive conductive ring 26 and the negative conductive ring 27. This design is ingenious, not only setting up the insulation part, but also achieving installation and fixation. In addition, as shown in Figure 12 、 25 , the positive conductive ring 26 and the negative conductive ring 27 also become the skeleton of the first rotation matching part 12, significantly improving the strength of the first rotation matching part 12, thereby further facilitating the support of the first bearing 41, the drive shaft 44, the first shaft 14, the inner cylinder 4 and the outer cylinder 3. This is of great significance because the weight increases after the structure is increased, and better rotation support is more conducive to performance.

[0091] In the foregoing structure, in order to facilitate electrical connection, the positive conductive ring 26 is provided with a positive lead-out sheet 28, and the negative conductive ring 27 is provided with a negative lead-out sheet 29, thereby further simplifying the wiring operation in production and assembly, and further facilitating the improvement of production efficiency. In addition, when the positive conductive ring 26 and the negative conductive ring 27 are integrally injection molded with the support 48, the positive lead-out sheet 28 and the negative lead-out sheet 29 are also integrally injection molded, thereby solving the problem of fixation, and on the other hand, it is also conducive to reinforcing the strength of the support 48, having the effect of killing two birds with one stone.

[0092] In order to contact better, in this case, as shown in Figure 6 , the contact and the inner surface of the conductive ring are electrically connected by elastic connection, such as the positive contact sheet and the negative contact sheet, which are positive elastic sheet 32 and negative elastic sheet 33. The positive elastic sheet 32 and the negative elastic sheet 33 are, for example, spring sheets, and the spring sheets are provided with contacts and are arranged in an arc shape and are distributed in an axial direction around the first shaft 14. The first shaft 14 is provided with a mounting socket 51 for installing the corresponding spring sheet.

[0093] In addition, the positive electrode contact piece and the negative electrode contact piece are integrally formed with the first input end by injection molding, which has the advantage that, since the positive electrode contact piece and the negative electrode contact piece need to be provided with parts that are introduced into the inner cylinder body 4, i.e. the positive electrode pin 30 and the negative electrode pin 31, and the electrical connection with the electric heating body 2 is achieved through the positive electrode pin 30 and the negative electrode pin 31, in this example, the positive electrode contact piece and the positive electrode pin 30 are integrally designed, the negative electrode contact piece and the negative electrode pin 31 are integrally designed, and are integrally formed with the first input end by injection molding, the positive electrode pin 30 and the negative electrode pin 31 are sealed on the inner side through the first end, and the contact points of the positive electrode contact piece and the negative electrode contact piece are on the outer side. This design has great advantages, on the one hand, the electrical connection is stable and reliable, and the safety is guaranteed, on the other hand, it greatly facilitates production and assembly, and on the other hand, it effectively simplifies the structure, which is conducive to compact structure.

[0094] The electrical connection structure can also be other structures, such as: the positive electrode conductive part and the negative electrode conductive part are each provided with an axial contact conductive part, i.e. the positive electrode axial contact conductive part 22 and the negative electrode axial contact conductive part 23, and the positive electrode contact piece and the negative electrode contact piece are each a ring-shaped contact piece, i.e. the positive electrode ring-shaped contact piece 24 and the negative electrode ring-shaped contact piece 25, and the ring-shaped side surface of the ring-shaped contact piece is used for axial abutting electrical connection with the axial contact conductive part. This design has certain advantages, such as simple and compact structure, stable and reliable connection, and convenient production and manufacturing.

[0095] In this example, the contact connection between the positive electrode contact piece and the positive electrode conductive part, and the contact connection between the negative electrode contact piece and the negative electrode conductive part each adopt a carbon brush structure, i.e. the contact points adopt a carbon brush positive electrode 35 and a carbon brush negative electrode 36. This has low cost, facilitates axial disassembly, and has stable and reliable connection.

[0096] In order to prevent the outer cylinder body 3 and the inner cylinder body 4 from loosening after being connected, an elastic abutting structure can be provided between the outer cylinder body 3 and the inner cylinder body 4, which is used to elastically abut and connect the outer cylinder body 3 and the inner cylinder body 4 with each other after the roller brush is connected to the roller brush holder. By using the elastic abutting structure, the outer cylinder body 3 and the inner cylinder body 4 can be automatically elastically separated when they are disassembled, i.e. automatically loosened, thereby facilitating the user to disassemble the outer cylinder body 3 and the inner cylinder body 4. The aforementioned structure can play a greater role in the third embodiment, i.e. once the detachable connection structure between the first rotation support end and the first side 10 is loosened, the outer cylinder body 3 can be automatically elastically separated away from the second side 11, i.e. loosened, thereby greatly facilitating the user to disassemble the outer cylinder body 3 for replacement, which greatly improves the user experience.

[0097] As Figure 11 , 19As shown, the elastic abutting structure comprises an elastic column 38 supported by the elastic member 37, which is arranged in the outer cylinder 3 and located at one end of the inner cylinder 4, and is used to elastically abut against one end of the inner cylinder 4. This structure is simple and convenient to use.

[0098] The second side 11 is provided with a driving structure connected with the other end of the inner cylinder 4 and / or connected with the other end of the outer cylinder 3, which is used to drive the inner cylinder 4 and / or the outer cylinder 3 to rotate. With the design of the other designs of embodiment three, the arrangement of the driving structure can be greatly simplified, which is conducive to improving the compactness of the structure, controlling the overall structure size, and also facilitating production and assembly. In this example, the driving structure is connected with the other end of the inner cylinder 4, which is used to drive the inner cylinder 4 to rotate, and the inner cylinder 4 and the outer cylinder 3 are driven to rotate through the circumferential transmission structure, thereby further achieving the purpose of simplifying the structure, and also facilitating production and use.

[0099] In order to illustrate the dynamic driving process, the electric motor assembly 49 is further illustrated as follows in this example: the driving structure is connected with the electric motor assembly 49 through the support 48, the output shaft of the electric motor assembly 49 is connected with the first driving wheel 45, the support 48 is installed with the first bearing 41, the first bearing 41 rotatably supports the right end of the driving shaft 44, the right end of the driving shaft 44 is also installed with the second driving wheel 46, the left end of the driving shaft 44 is connected with the first shaft 14 in cooperation, and the first driving wheel 45 and the second driving wheel 46 are connected with the driving belt 47. The working principle is that the output shaft of the electric motor assembly 49 drives the first driving wheel 45, the first driving wheel 45 drives the second driving wheel 46 through the driving belt 47, the second driving wheel 46 drives the driving shaft 44, the driving shaft 44 drives the inner cylinder 4 to rotate, and the inner cylinder 4 and the outer cylinder 3 are driven to rotate through the circumferential transmission structure. The rotating structure at one end of the outer cylinder 3 can be referred to embodiment two, and the rotating structure at one end of the outer cylinder 3 is realized through the rotating connecting shaft 40 and the second bearing 42 between the first side 10 and the outer cylinder 3. However, the outer cylinder 3 is provided with the second shaft 19 and the second circumferential part 20, and the second circumferential part 20 is connected with the outer cylinder 3 for circumferential transmission. The specific structure is that the second shaft 19 simultaneously serves as the rotating connecting shaft 40, the second shaft 19 is arranged in the second rotating cooperation part 17, the second rotating cooperation part 17 is fixedly arranged after connecting the roller brush holder, the second bearing 42 rotatably supports the second shaft 19, the second shaft 19 is connected with the second circumferential part 20, and the second shaft 19 rotates with the outer cylinder 3 through the second circumferential part 20, that is, rotates with the roller brush. When the roller brush rotates, it is rotatably supported by the second bearing 42, thereby realizing the rotating structure at one end of the outer cylinder 3, that is, the rotating structure at one end of the roller brush. The foregoing structure can be referred to Figure 11 、 12 as shown.

[0100] In this example, the elastic structure is further optimized, which can significantly simplify the structure, facilitate production and assembly, and be conducive to the control of the axial size. Specifically, the second shaft 19 and the second peripheral part 20 are connected into an independent sleeve assembly, the second shaft 19 includes an outer end and an inner end, the outer end is connected with the second bearing 42, and the inner end is used for mounting the elastic column 38. The elastic member 37 is arranged between the inner end and the elastic column 38. After the design, the elastic structure can be set first, and then the sleeve assembly is connected with the outer cylinder 3, which is very convenient for production and assembly, and the structure is simple and compact.

[0101] Additionally, as shown in Figure 11 the partition part 52 is arranged, the second shaft 19 and the second peripheral part 20 are connected with the partition part respectively, and the second shaft 19, the second peripheral part 20 and the partition part 52 form an integrated cylindrical structure. In this way, the second shaft 19 is divided into an outer end and an inner end by the partition part 52, the partition part 52 can play a good isolation, and at the same time, the second shaft 19 and the second peripheral part 20 are also well supported, thereby facilitating the addition of the electric heating body.

[0102] The cleaning part 1 can be arranged in the same way as in example two.

[0103] Example four:

[0104] Compared with example three, example four can be that the first rotating support end is detachably connected with the first side 10, the second rotating support end is detachably connected with the second side 11, and the two detachable connections of the rolling brush with the first rotating support end and the first side 10 and the second rotating support end and the second side 11 can realize the overall detachable connection with the rolling brush frame.

[0105] The dismounting structure of the outer cylinder 3 is that, after the two detachable connections of the rolling brush with the first rotating support end and the first side 10 and the second rotating support end and the second side 11 are integrally dismounted from the rolling brush frame, the outer cylinder 3 and the inner cylinder 4 are dismounted and separated along the axial direction through the mutual detachable sleeve connection structure.

[0106] From the above, compared with example three, the main difference is that the inner cylinder 4 is also dismounted.

[0107] Example five: a cleaning device is provided with a suction port, and the suction port is provided with the rolling brush.

[0108] The cleaning device refers to a household cleaning device or a small cleaning device, which is also a feature of the roll brush, and the overall structure size is well controlled, so that the roll brush can be applied to a small cleaning device. In addition, such cleaning devices are not high in price and are cost sensitive, so another feature of the roll brush is low cost. As known from the above, the roll brush reduces the cost through structural improvement, and also reduces the cost through the proposed structure for convenient production and assembly, so that the roll brush can be applied to a cleaning device, and the user can bear the purchase cost. In addition, through the split structure design, the user does not need to spend a lot of cost every time the roll brush is replaced.

[0109] The specific arrangement of the electric heating body 2 can also be changed, such as embedding the electric heating body 2 in the cylinder.

[0110] The cylinder can adopt a heat conductor and / or a heat conduction layer arranged between the inner periphery of the cylinder and the electric heating body 2, so as to improve the heat utilization rate.

[0111] The electric heating body 2 is one or more, and is arranged around the cylinder axis. In the example, there are multiple, which is beneficial to more uniform distribution of heat, so as to uniformly heat. The electric heating body 2 arranged around the cylinder axis can refer to Figure 3 、 17 , 22, as can be seen from the figure, the electric heating body 2 is uniformly arranged around the cylinder axis, and can also be grouped along the axis direction, and the adjacent groups are arranged in a circumferential direction. The electric heating body 2 in each group is uniformly arranged around the cylinder axis.

[0112] In order to be more convenient to disassemble and assemble, the first rotating support end is provided with a disassembling handle 7, one end of the disassembling handle 7 is connected with the rotating structure of the first rotating support end, and the other end of the disassembling handle 7 is provided with a locking structure, such as a lock tongue. The first rotating support end is locked on the first side 10 through the lock tongue. The structure is simple and reliable, and does not need to be assisted by tools, and the disassembling operation is convenient.

[0113] In the present application, the electric heating body 2 can adopt an electric heating film. This is beneficial to further control the structure size, and also has good use performance.

[0114] The electric heating film is arranged on the outer periphery of the cylinder and located between the cleaning part 1 and the outer periphery of the cylinder. This is beneficial to convenient production and manufacturing, and also beneficial to shorten the transmission path and reduce the loss, so that the infrared radiation and / or heat converted by the electric heating film is more to heat the cleaning part 1 and / or the cleaned surface and / or the liquid in the cleaning part 1 and / or the liquid on the cleaned surface.

[0115] The electric heating film, such as carbon fiber electric heating film, is heated by the principle that the carbon molecular groups in the heating body produce "Brown motion" under the action of electric field, the carbon molecules rub and collide with each other, and the generated heat energy is transmitted to the outside in the form of far infrared radiation and convection, and the conversion rate of electric energy and heat energy is as high as 98% or more. The action of carbon molecules makes the surface of the system rapidly heat up.

[0116] In understanding the present application, the above-described structure can refer to other embodiments / appendices if necessary Figure 1 And it is understood that here is not redundant.

[0117] The above-described is only the embodiment of the present application for illustration, therefore, equivalent changes or modifications made to the structure, features and principles described in the scope of the patent protection of the present application are included in the scope of the patent protection of the present application.
