Description

Technical Field

[0001] This application belongs to the field of cleaning equipment technology, specifically relating to a cleaning component and cleaning equipment. Background Technology

[0002] Cleaning equipment, such as cleaning robots, is generally equipped with a rotary drive, a rotating disk, and a cleaning cloth. The cleaning cloth is attached to the rotating disk, and the rotating disk is usually equipped with a magnetic attachment. The magnetic attachment magnetically engages with the rotary drive, thereby connecting the magnetic attachment to the rotary drive and preventing the two from separating.

[0003] However, in traditional designs, the magnetic components are prone to detaching from the rotating disk, resulting in poor reliability of the connection between the rotating drive and the rotating disk, thus causing a high failure rate of the cleaning components. Utility Model Content

[0004] The purpose of this application is to provide a cleaning component and cleaning equipment that can solve the problem of high failure rate of cleaning components in related technologies.

[0005] In a first aspect, embodiments of this application provide a cleaning component, comprising:

[0006] Rotating disk;

[0007] A first magnetic attractor and a pressure ring are provided. The first magnetic attractor is disposed on the rotating disk. The pressure ring is connected to the rotating disk, and a portion of the first magnetic attractor is sandwiched between at least a portion of the pressure ring and the rotating disk. The inner cavity of the pressure ring can accommodate at least a portion of the rotary drive member. The first magnetic attractor and the inner cavity of the pressure ring are arranged opposite to each other in the centerline direction of the pressure ring, and the first magnetic attractor can magnetically engage with the portion of the rotary drive member located in the inner cavity of the pressure ring.

[0008] Secondly, embodiments of this application also provide a cleaning device, which includes a rotary drive and the cleaning components described above, wherein at least a portion of the rotary drive is located in the inner cavity of the pressure ring and magnetically engages with the first magnetic member.

[0009] In this embodiment, the pressure ring is connected to the rotating disk, and a portion of the first magnetic member is sandwiched between at least a portion of the pressure ring and the rotating disk. With this configuration, the first magnetic member is indirectly connected to the rotating disk via the pressure ring, and the pressure ring restricts the first magnetic member from moving away from the rotating disk. In other words, the pressure ring restricts the first magnetic member from detaching from the rotating disk, reducing the probability of it falling off. Consequently, the rotation drive and the rotating disk are less likely to separate, resulting in a lower failure rate for the cleaning assembly. Attached Figure Description

[0030] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0031] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0032] The cleaning components and cleaning equipment provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0033] Please refer to Figures 1 to 13 As shown in the embodiment of this application, a cleaning component is provided, which includes: a rotating disk 100, a first magnetic suction member 200, and a pressure ring 300.

[0034] Specifically, the rotating disk 100 is, for example, a disc. A first magnetic chuck 200 is disposed on the rotating disk 100, and a pressure ring 300 is connected to the rotating disk 100. A portion of the first magnetic chuck 200 is sandwiched between at least a portion of the pressure ring 300 and the rotating disk 100. The inner cavity of the pressure ring 300 can accommodate at least a portion of the rotation drive component. The first magnetic chuck 200 and the inner cavity of the pressure ring 300 are arranged opposite each other in the direction of the centerline of the pressure ring 300, for example, as follows: Figure 3 The direction indicated by the middle arrow line A, and the first magnetic attracting member 200 can magnetically engage with the part of the rotary drive member located in the inner cavity of the pressure ring 300.

[0035] The rotary drive includes, for example, a motor, whose output shaft is provided with a third magnetic chuck, which is located in the inner cavity of the pressure ring 300 and magnetically engages with the first magnetic chuck 200.

[0036] In conventional designs, the first magnetic member 200 is directly connected to the rotating disk 100, for example. However, in this embodiment, the pressure ring 300 is connected to the rotating disk 100, and a portion of the first magnetic member 200 is sandwiched between at least a portion of the pressure ring 300 and the rotating disk 100. With this arrangement, the first magnetic member 200 is indirectly connected to the rotating disk 100 via the pressure ring 300, and the pressure ring 300 restricts the first magnetic member 200 from moving away from the rotating disk 100; that is, the pressure ring 300 prevents the first magnetic member 200 from detaching from the rotating disk 100.

[0037] Compared to the traditional design where the first magnetic suction component 200 is directly connected to the rotating disk 100, the solution provided in this embodiment adds a pressure ring 300, which can prevent the first magnetic suction component 200 from falling off the rotating disk 100. This reduces the probability of the first magnetic suction component 200 falling off the rotating disk 100, making it less likely for the rotating drive component and the rotating disk 100 to separate, thus reducing the failure rate of the cleaning component.

[0038] In one alternative embodiment, reference is made to... Figure 10 As shown, the inner wall of the pressure ring 300 is provided with a connecting rib 340, and the part of the rotary drive member located in the inner cavity of the pressure ring 300 is provided with a groove, and the connecting rib 340 is located in the groove, so that the rotary drive member is connected to the pressure ring 300 in a transmission, thereby enabling the rotary drive member to drive the pressure ring 300 to rotate.

[0039] In actual use, the first magnetic suction component 200 magnetically engages with the rotary drive component to prevent the rotary disk 100 and the rotary drive component from moving relative to each other in the direction of the center line of the pressure ring 300. The connecting rib 340 engages with the groove so that the pressure ring 300 can rotate with the rotary drive component. The pressure ring 300 is connected to the rotary disk 100 so that the rotary disk 100 rotates with the rotary drive component.

[0040] In another embodiment, reference Figure 3 and Figure 13As shown, the first magnetic attractor 200 is located in the inner cavity of the pressure ring 300, and the end of the first magnetic attractor 200 facing the rotary drive member is provided with a stepped groove 210 along its own circumference. The inner wall of the pressure ring 300 is provided with a limiting ring 310 along its own circumference. The limiting ring 310 is located in the stepped groove 210 and is in upper limit engagement with the groove wall of the stepped groove 210 in the direction of the center line of the pressure ring 300. The inner wall of the limiting ring 310 and the groove wall of the stepped groove 210 are in upper limit engagement in the direction perpendicular to the center line of the pressure ring 300, so as to restrict the movement of the first magnetic attractor 200 in the plane perpendicular to the center line of the pressure ring 300.

[0041] In this embodiment, the pressure ring 300 can not only restrict the movement of the first magnetic member 200 in the direction of the center line of the pressure ring 300, but also restrict the movement of the first magnetic member 200 in a plane perpendicular to the center line of the pressure ring 300, thereby improving the stability of the first magnetic member 200.

[0042] In other alternative embodiments, the first magnetic accumulator 200 may not have the stepped groove 210. In this case, the first magnetic accumulator 200 is, for example, a cylindrical structure. The center line of the first magnetic accumulator 200 is parallel to or coincides with the center line of the pressure ring 300, and the limiting ring 310 is, for example, pressed on the side of the first magnetic accumulator 200 facing the rotating drive member.

[0043] In one alternative embodiment, reference is made to... Figure 3 and Figure 13 As shown, in the direction of the centerline of the pressure ring 300, the end face of the first magnetic member 200 facing the rotary drive member protrudes beyond the end face of the limiting ring 310 facing the rotary drive member. Optionally, referring to... Figure 13 As shown, the end face of the first magnetic member 200 facing the rotary drive member is, for example, the first surface 220 of the first magnetic member 200, for reference. Figure 10 As shown, the end face of the limiting ring 310 facing the rotary drive member is, for example, the second face 311 of the limiting ring 310. With this configuration, the rotary drive member only contacts the first magnetic member 200, while there is a gap between the rotary drive member and the limiting ring 310. This prevents the limiting ring 310 from interfering with the engagement between the rotary drive member and the first magnetic member 200, thereby resulting in a higher degree of engagement between the rotary drive member and the first magnetic member 200, and thus a more reliable connection between the rotary drive member and the first magnetic member 200.

[0044] In other alternative embodiments, the end face of the first magnetic member 200 facing the rotary drive member may also be flush with the end face of the limiting ring 310 facing the rotary drive member, or the end face of the first magnetic member 200 facing the rotary drive member may also be located inside the limiting ring 310.

[0045] In another embodiment, reference Figure 3As shown, the end of the pressure ring 300 facing the rotating disk 100 is in contact with the rotating disk 100, and the pressure ring 300 and the rotating disk 100 are in upper limit engagement along the centerline direction of the pressure ring 300. With this configuration, during actual use, the pressure ring 300 and the rotating disk 100 are less likely to move relative to each other along the centerline direction of the pressure ring 300, thus making the operation of the cleaning component more stable and reliable. In addition, with this configuration, when the pressure ring 300 and the rotating disk 100 are in contact, it indicates that the pressure ring 300 and the rotating disk 100 are properly installed, thereby reducing the assembly difficulty of the pressure ring 300 and the rotating disk 100.

[0046] In other alternative embodiments, a gap may also exist between the end of the pressure ring 300 facing the rotating disk 100 and the rotating disk 100.

[0047] In another embodiment, reference Figure 3 and Figure 10 As shown, the rotating disk 100 is provided with a connecting cylinder 110. A portion of the pressure ring 300 and the first magnetic suction member 200 are located inside the connecting cylinder 110, while another portion of the pressure ring 300 is located outside the connecting cylinder 110 and is provided with a limiting part 330. The limiting part 330 and the connecting cylinder 110 are engaged in a limiting fit along the centerline direction of the pressure ring 300. With this arrangement, the limiting part 330 and the connecting cylinder 110 cooperate with each other to restrict the relative movement of the pressure ring 300 and the rotating disk 100 along the centerline direction of the pressure ring 300, which also makes the operation of the cleaning component more stable and reliable. In addition, with this arrangement, when the limiting part 330 and the connecting cylinder 110 are in contact, it also indicates that the pressure ring 300 and the rotating disk 100 are installed in place. Thus, the assembly difficulty of the pressure ring 300 and the rotating disk 100 is also reduced by the solution of this embodiment.

[0048] Optionally, refer to Figure 10 As shown, a portion of the sidewall of the pressure ring 300 extends, for example, in a direction away from the center line of the pressure ring 300, thereby forming a limiting portion 330. Additionally, refer to... Figures 5-8 As shown, the rotating disk 100 includes, for example, a disk body 140 and a connecting cylinder 110, and the disk body 140 and the connecting cylinder 110 are, for example, an integral structure. The disk body 140 is the main body of the rotating disk 100, and the first magnetic suction member 200 and the cleaning cloth of the cleaning device are, for example, both provided on the disk body 140.

[0049] Furthermore, the number of limiting parts 330 is, for example, two. The two limiting parts 330 are symmetrically arranged about a plane parallel to the center line of the pressure ring 300. The center line of the pressure ring 300, the center line of the connecting cylinder 110, and the center line of the disk body 140 coincide. In this way, the force between the pressure ring 300 and the rotating disk 100 is distributed more evenly in the circumferential direction of both the pressure ring 300 and the rotating disk 100, thereby extending the service life of both the pressure ring 300 and the rotating disk 100. It should be noted that the number of limiting parts 330 can be arbitrary; the specific number of limiting parts 330 in this embodiment is not limited.

[0050] In other alternative embodiments, the pressure ring 300 may also omit the limiting portion 330.

[0051] In another embodiment, reference Figure 3 As shown, the rotating disk 100 is provided with a connecting cylinder 110. At least a portion of the pressure ring 300 and the first magnetic suction member 200 are located in the inner cavity of the connecting cylinder 110, and the pressure ring 300 and the connecting cylinder 110 are in a circumferential upper limit engagement. With this arrangement, the relative rotation between the pressure ring 300 and the rotating disk 100 is restricted, thereby making the operation of the cleaning assembly more stable and reliable.

[0052] As one specific implementation method, refer to Figure 5 and Figure 9 As shown, the pressure ring 300 is provided with the limiting part 330 mentioned above. The end face of the connecting cylinder 110 facing the limiting part 330 is provided with, for example, a limiting groove 111. At least a part of the limiting part 330 is located in the limiting groove 111 and is in a limiting fit with the groove wall of the limiting groove 111 in the circumferential direction of the connecting cylinder 110, thereby realizing the limiting fit between the pressure ring 300 and the connecting cylinder 110 in the circumferential direction of the pressure ring 300.

[0053] In other alternative embodiments, the pressure ring 300 and the connecting cylinder 110 may not have a limiting fit relationship in the circumferential direction of the pressure ring 300.

[0054] In another embodiment, reference Figure 5 As shown, the rotating disk 100 is provided with at least two positioning parts 120, the exact number of which depends on actual needs. Each positioning part 120 is spaced apart circumferentially along the first magnetic member 200, and each positioning part 120 is engaged with the first magnetic member 200 in a direction perpendicular to its center line. With this arrangement, the first magnetic member 200 can be positioned relatively easily and quickly in the plane perpendicular to its center line by means of at least two positioning parts 120, thereby reducing the assembly difficulty between the first magnetic member 200 and the rotating disk 100.

[0055] Further, refer to Figure 5As shown, the positioning part 120 extends along the direction close to the center line of the rotating disk 100 on the side facing the first magnetic member 200, and forms a positioning protrusion 121, which contacts the first magnetic member 200. With this arrangement, the contact area between the positioning part 120 and the first magnetic member 200 is small, thereby reducing the friction between the positioning part 120 and the first magnetic member 200, and thus reducing the assembly difficulty of the first magnetic member 200.

[0056] In other alternative embodiments, the rotating disk 100 may also omit the positioning part 120.

[0057] In another embodiment, the cleaning assembly further includes a threaded component, and the pressure ring 300 and the rotating disk 100 are detachably connected, for example, via the threaded component. In conventional designs, the first magnetic component 200 is connected to the rotating disk 100, for example, by adhesive bonding. Adhesive bonding is relatively complex, and when the first magnetic component 200 includes a magnet, special adhesive is required to bond the magnet to the rotating disk 100, resulting in high connection costs between the first magnetic component 200 and the rotating disk 100. In this embodiment, the pressure ring 300 and the rotating disk 100 are connected by a threaded component, thereby indirectly connecting the first magnetic component 200 to the rotating disk 100. Compared to adhesive bonding, the solution provided in this embodiment is simpler to operate and lower in cost. Furthermore, using the solution provided in this embodiment, the pressure ring 300 and the rotating disk 100 can be easily disassembled and assembled, making the replacement of the pressure ring 300, the rotating disk 100, and the first magnetic component 200 more convenient.

[0058] In other alternative embodiments, the pressure ring 300 and the rotating disk 100 can also be connected by adhesive. It should be noted that in actual operation, the pressure ring 300 and the rotating disk 100 can be connected in any way, and this embodiment of the application does not impose any restrictions on this.

[0059] In another embodiment, reference Figure 3 and Figure 6 As shown, the cleaning assembly also includes a second magnetic member 400 and a connector 500. The rotating disk 100 has a receiving groove 130 on the side facing away from the pressure ring 300. The second magnetic member 400 is located in the receiving groove 130, and the second magnetic member 400, the rotating disk 100 and the pressure ring 300 are connected by the connector 500. The second magnetic member 400 is used to magnetically engage with the fixed base of the cleaning equipment.

[0060] In this embodiment, the second magnetic chuck 400 can be reliably connected to the rotating disk 100 by means of the connector 500, thereby reducing the probability of the second magnetic chuck 400 falling off the rotating disk 100. In addition, the second magnetic chuck 400, the rotating disk 100, and the pressure ring 300 are connected by the connector 500. In this way, by means of the same connector 500, the second magnetic chuck 400 and the rotating disk 100 are connected to each other. This reduces the number of parts involved in the cleaning assembly, thereby reducing the assembly difficulty of the cleaning assembly.

[0061] In actual use, a cleaning cloth is usually connected to the rotating disk 100. Before cleaning the cleaning cloth, the second magnetic component 400 magnetically engages with the fixed base to position the rotating disk 100. During the cleaning process, the driving force provided by the rotating drive component is greater than the magnetic force between the second magnetic component 400 and the fixed base, so that the rotating drive component can drive the rotating disk 100 to rotate relative to the fixed base, thereby achieving the cleaning of the cleaning cloth.

[0062] As one specific implementation, the connector 500 is, for example, the threaded component mentioned above.

[0063] In other alternative embodiments, the second magnetic member 400 may also be interference-fitted with the receiving groove 130 to connect the second magnetic member 400 to the rotating disk 100. Alternatively, the connector 500 may also be used solely for connecting the second magnetic member 400 to the rotating disk 100.

[0064] In a further embodiment, reference is made to... Figure 2 As shown, the number of connectors 500 is, for example, at least two, and each connector 500 is spaced apart along the circumference of the second magnetic member 400. With this arrangement, the pressure ring 300, the rotating disk 100 and the second magnetic member 400 are connected by at least two connectors 500, thereby making the connection between the pressure ring 300, the rotating disk 100 and the second magnetic member 400 more reliable.

[0065] As one specific implementation method, refer to Figure 2 As shown, the number of connectors 500 is, for example, three, and the three connectors 500 are arranged in a roughly triangular pattern, with the three connectors 500 located at the three vertices of the triangle.

[0066] It should be noted that the more connectors 500 there are, the better the connection reliability between the pressure ring 300, the rotating disk 100, and the second magnetic suction member 400. In this embodiment, the specific number of connectors 500 is not limited, and can be selected according to actual needs. In addition, in other optional embodiments, the number of connectors 500 may also be one.

[0067] In a further embodiment, reference is made to... Figure 3 As shown, one end of the connector 500 is located inside the second magnetic member 400 and engages with the second magnetic member 400 at its upper limit in the direction near the rotating disk 100. The other end of the connector 500 passes through the second magnetic member 400 and the rotating disk 100 in sequence and is connected to the pressure ring 300. This arrangement prevents the connector 500 from interfering with the engagement between the second magnetic member 400 and the fixed base, which facilitates good contact between the second magnetic member 400 and the fixed base, thus making the engagement between the second magnetic member 400 and the fixed base more reliable.

[0068] Optionally, the connector 500 may be, for example, the threaded component mentioned above, and one end of the threaded component may be provided with a nut, which is located inside the second magnetic component 400 and engages with the second magnetic component 400 in the direction close to the rotating disk 100.

[0069] In other alternative embodiments, one end of the connector 500 may also be located on the side of the second magnetic member 400 away from the pressure ring 300, and engage with the second magnetic member 400 in the direction close to the rotating disk 100.

[0070] In a further embodiment, reference is made to... Figure 4 and Figure 6 As shown, the second magnetic chuck 400 has at least two circumferentially spaced limiting surfaces 410, and the groove wall of the receiving groove 130 has at least two circumferentially spaced mating surfaces 131. The limiting surfaces 410 and mating surfaces 131 correspond one-to-one, and each limiting surface 410 is engaged with the corresponding mating surface 131 in a circumferentially spaced engagement with the second magnetic chuck 400. With this arrangement, the mutual rotation between the second magnetic chuck 400 and the rotating disk 100 is restricted by the interaction of the limiting surfaces 410 and the mating surfaces 131, thereby improving the stability of the second magnetic chuck 400.

[0071] In one specific implementation, initially, the second magnetic member 400 is, for example, a circular structure. Then, a portion of the circumferential edge of the second magnetic member 400 is cut off to form a limiting surface 410. Additionally, refer to... Figure 4 As shown, the portion of the circumferential edge of the second magnetic member 400 that has not been cut off has, for example, an opening 420, through which the connecting member 500 mentioned above passes, thereby passing through the second magnetic member 400.

[0072] In other alternative embodiments, the second magnetic member 400 may not have a limiting surface 410, and the receiving groove 130 may not have a mating surface 131. In this case, both the second magnetic member 400 and the receiving groove 130 may be circular structures, for example.

[0073] In a further embodiment, the first magnetic attractor 200 includes a magnet, and the second magnetic attractor 400 includes a ferromagnetic metal sheet. The magnet and the ferromagnetic metal sheet are magnetically attracted to each other, meaning that the first magnetic attractor 200 and the second magnetic attractor 400 are magnetically attracted to each other. With this configuration, the magnetic force between the first magnetic attractor 200 and the second magnetic attractor 400 can limit their movement away from each other, thereby restricting their movement away from the rotating disk 100 and improving the stability of both components. Furthermore, the ferromagnetic metal sheet has good wear resistance, resulting in a longer service life for the second magnetic attractor 400.

[0074] Alternatively, the ferromagnetic metal sheet may be, for example, an iron sheet.

[0075] In other alternative embodiments, there may be no magnetic attraction relationship between the first magnetic member 200 and the second magnetic member 400.

[0076] It should be noted that the first magnetic attractor 200, the second magnetic attractor 400 and the third magnetic attractor mentioned above are all magnetic attractors. Magnetic attractors may include a magnet or a component that can be attracted by a magnet. Specifically, the component that can be attracted by a magnet is, for example, the ferromagnetic metal sheet mentioned above.

[0077] In a further embodiment, reference is made to... Figure 3 As shown, the cleaning assembly also includes a connecting sleeve 600, which is embedded within the pressure ring 300. A portion of the connector 500 is located within the connecting sleeve 600 and is threadedly connected to the inner wall of the connecting sleeve 600. Optionally, the connector 500 may have an external thread, and correspondingly, the inner wall of the connecting sleeve 600 may have an internal thread. The external thread and the internal thread engage to achieve the threaded connection between the connector 500 and the inner wall of the connecting sleeve 600.

[0078] In this embodiment, the connection sleeve 600 helps to improve the connection reliability between the connector 500 and the pressure ring 300, thereby making the pressure ring 300, the rotating disk 100 and the second magnetic suction member 400 all more stable.

[0079] In one specific implementation, the pressure ring 300 is provided with a connecting post 320, and the connecting sleeve 600 is embedded in the connecting post 320. The connecting sleeve 600 is, for example, a metal sleeve, or more specifically, a copper sleeve.

[0080] As one specific implementation, the pressure ring 300 is, for example, an integral injection molded structure, and a connecting sleeve 600 is pre-embedded in the pressure ring 300 during injection molding.

[0081] In a further embodiment, the pressure ring 300 is provided with a connecting post 320, and the connector 500 includes a self-tapping screw, which is threadedly connected to the connecting post 320. Unlike the previous embodiment, where a connecting sleeve 600 is embedded within the connecting post 320 and the connector 500 is threadedly connected to the connecting sleeve 600, in this embodiment, the connecting sleeve 600 is not embedded within the connecting post 320. During actual assembly, the self-tapping screw is driven into the connecting post 320 and threadedly connected to it, thereby achieving the connection between the connector 500 and the pressure ring 300. Compared to the previous embodiment, the solution used in this embodiment involves fewer components, thus simplifying the structure of the cleaning assembly.

[0082] In one alternative embodiment, reference is made to...
