Description

Technical Field

[0001] This application relates to the field of cleaning device technology, and more particularly to a cleaning component and a cleaning device. Background Technology

[0002] Cleaning equipment is gradually evolving from basic intelligence to a higher level of automation, replacing manual cleaning and becoming an indispensable cleaning helper for many households, such as cleaning robots and handheld vacuum cleaners. In many of these technologies, the roller brushes on cleaning equipment are replaceable. The roller brush is usually integrated with the support frame, and replacing it requires disassembling both the frame and the brush, a relatively complex process. Utility Model Content

[0003] This application provides a cleaning component and a cleaning device that allows for the separate disassembly of the roller brush, facilitating the replacement of the roller brush in the cleaning component.

[0004] In a first aspect, embodiments of this application provide a cleaning component, including:

[0005] The housing has a receiving cavity and a first opening communicating with the receiving cavity, and the housing is provided with an output part for drive connection with an external motor.

[0006] The mounting bracket includes a bracket body and a rotating part. The rotating part is disposed on the side of the bracket body and is rotatably connected to the housing about a first axis, so as to drive the bracket body to rotate about the first axis.

[0007] The roller brush is detachably connected to the main body of the bracket. The roller brush is rotatable relative to the housing about a second axis line of the roller brush, and the second axis line is parallel to the first axis line.

[0008] When the support body rotates relative to the housing around the first axis, it drives the roller brush to enter and exit the receiving cavity through the first opening.

[0009] Secondly, this application also provides a cleaning device, including a main unit, a drive component, and a cleaning component as described in any of the above embodiments. The drive component and the cleaning component are both disposed on the main unit, and the drive component is used to drive the roller brush to rotate around the second axis.

[0010] Based on the cleaning components and cleaning devices in the embodiments of this application, this embodiment installs the roller brush by setting a mounting bracket. The user can manually adjust the movement of the bracket body relative to the housing so that the roller brush can move synchronously with the bracket body and leave the receiving cavity. This allows the mounting bracket to be reused repeatedly. The roller brush can be disassembled and replaced individually without disassembling the mounting bracket, which simplifies the installation and replacement steps of the roller brush and reduces the cost of replacement consumables in the cleaning components.

[0029] To more clearly illustrate the technical solutions in the embodiments of this application or related technologies, a clear and complete description will be provided below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0030] In related technologies, the roller brushes on many cleaning devices are replaceable. The roller brush is usually assembled with the bracket. When replacing the roller brush, the bracket and the roller brush need to be disassembled together. The disassembly process is complicated, and the roller brush and the bracket need to be replaced together, which will increase the cost of replacement consumables.

[0031] Regarding the above situation, firstly, please refer to [link / reference needed]. Figures 1-3 This application proposes a cleaning component 1, which can generally be installed as an integral structure in a cleaning device 2. The cleaning component 1 includes a housing 10, a mounting bracket 20, and a roller brush 30. The roller brush 30 is installed in the housing 10 through the mounting bracket 20. The housing 10 has a receiving cavity 11 and a first opening 12 communicating with the receiving cavity 11. After the roller brush 30 is installed in the receiving cavity 11, the receiving cavity 11 is a semi-enclosed cavity. The receiving cavity 11 communicates with the outside through the first opening 12. A part of the roller brush 30 extends out of the receiving cavity 11 through the first opening 12. The roller brush 30 exposed outside the receiving cavity 11 is used to sweep the floor.

[0032] like Figures 2-3As shown, the mounting bracket 20 includes a bracket body 24 and a rotating part 23. The rotating part 23 is disposed on the side of the bracket body 24 and is rotatably connected to the housing 10 around a first axis L1, thereby driving the bracket body 24 to rotate around the first axis L1. The roller brush part 30 is detachably connected to the bracket body 24 and can rotate relative to the housing 10 around a second axis L2. The first axis L1 and the second axis L2 are parallel. When the bracket body 24 rotates relative to the housing 10 around the first axis L1, the bracket body 24 can drive the roller brush part 30 to enter and exit the receiving cavity 11 through the first opening 12, making the disassembly and replacement of the roller brush part 30 easier.

[0033] Specifically, the housing 10 provides a base and installation space for the mounting bracket 20 and the roller brush 30, such as Figure 1 As shown, the rotating part 23 is a rotating shaft, which is located on one side of the bracket body 24. For example, the orthographic projection of the bracket body 24 along the first axis L1 coincides with the edge of the orthographic projection of the rotating part along the first axis L1. When the rotating shaft rotates, it can drive the bracket body 24 to rotate as a whole. The bracket body 24 is rotatably connected to the housing 10 around the first axis L1 through the rotating shaft, and the first axis L1 is the axis of the rotating shaft. For example, the bracket body 24 can be in the shape of a disk, the rotating part 23 is located on the periphery of the disk of the bracket body 24, and the brush part 30 is disposed on the disk of the bracket body 24. The second axis L2 of the brush part 30 is the axis of the disk, so the first axis L1 and the second axis L2 do not coincide.

[0034] It should be noted that in this embodiment, the roller brush 30 is installed by setting the bracket body 24. The user can manually adjust the movement of the bracket body 24 relative to the housing 10 so that the roller brush 30 can move synchronously with the bracket body 24 and leave the receiving cavity 11. This allows the mounting bracket 20 to be reused repeatedly. The roller brush 30 can be disassembled and replaced separately without disassembling the mounting bracket 20, which simplifies the installation and replacement steps of the roller brush 30 and reduces the cost of replacement consumables in the cleaning component 1.

[0035] It should also be noted that the surface of the roller brush 30 may be provided with cleaning elements, such as bristles and / or brush strips, or the roller brush 30 may be a roller cloth. During the rotation of the roller brush 30, the cleaning elements of the roller brush 30 can come into contact with dust and other impurities on the surface to be cleaned, and remove the impurities from the surface to be cleaned during the rotation of the roller brush 30. In order to prevent the cleaning component 1 from deforming during rotation, both the transmission part 22 for driving the roller brush 30 to rotate and the mounting bracket 20 for mounting the cleaning component 1 can be made of metal. Among them, the rotation angle of the rotating part 23 driving the bracket body 24 to rotate around the first axis L1 is α, where α satisfies 0≤α≤90°.

[0036] Please see Figure 1 In some embodiments of this application, the housing 10 is provided with an output part 13 for transmission connection with an external motor; the bracket body 24 is provided with a transmission part 22 for transmission connection with the output part 13. The transmission part 22 is rotatably connected to the bracket body 24 through a bearing. The transmission part 22 is connected to the roller brush part 30, and the transmission part 22 can drive the roller brush part 30 to rotate around the second axis L2.

[0037] Specifically, the transmission unit 22 is mounted on the bracket body 24 and is rotatably connected to the bracket body 24 via bearings. An external motor can provide rotational torque to drive the output unit 13 to rotate the transmission unit 22. When the roller brush 30 is connected to the transmission unit 22, the transmission unit 22 can also drive the roller brush 30 to rotate synchronously. That is, when the transmission unit 22 rotates relative to the mounting bracket 20 around the second axis L2, the transmission unit 22 can drive the roller brush 30 to rotate relative to the mounting bracket 20 around the second axis L2. The bracket body 24 can be disc-shaped, with the rotating part 23 located on the periphery of the disc of the bracket body 24, and the transmission unit 22 located at the center of the disc of the bracket body 24.

[0038] Please see Figure 1 In some embodiments of this application, the bracket body 24 is slidably connected to the rotating part 23, and the bracket body 24 can slide relative to the rotating part 23 along the extension direction of the first axis L1 so that the transmission part 22 can contact and separate from the output part 13.

[0039] Understandably, when the cleaning component 1 is in operation, the output section 13 and the transmission section 22 are connected by transmission. The output section 13 can drive the transmission section 22 to rotate. When the roller brush section 30 is disassembled, the support body 24 needs to be rotated around the first axis L1, so that the support body 24 and the roller brush section 30 rotate away from the receiving cavity 11. In order to reduce the interference of the output section 13 on the movement of the transmission section 22, the support body 24 can slide along the extension direction of the first axis L1, so that the transmission section 22 and the output section 13 are separated first, and then the support body 24 is rotated, thereby avoiding the output section 13 interfering with the rotation process of the transmission section 22. After the roller brush section 30 is installed on the transmission section 22, the support body 24 can be rotated into the receiving cavity 11 first, and then the support body 24 can be slid along the extension direction of the first axis L1, so that the transmission section 22 and the output section 13 are in transmission contact, and the output section 13 can drive the transmission section 22 to rotate.

[0040] Please see Figure 4In some embodiments of this application, the cleaning component 1 further includes a limiting member 41, which is detachably connected to the housing 10. Thus, the limiting member 41 can move relative to the housing 10 so that it can contact the side of the mounting bracket 20 facing the roller brush portion 30, thereby restricting the sliding of the bracket body 24 relative to the rotating portion 23. That is, when the limiting member 41 is connected to the housing 10, the limiting member 41 is located on the side of the mounting bracket 20 facing the roller brush portion 30, and the housing 10 and the limiting member 41 are clamped on opposite sides of the mounting bracket 20, thereby preventing the bracket body 24 from sliding relative to the rotating axis 21 along the extension direction of the first axis L1, thereby preventing the roller brush portion 30 from jumping during operation.

[0041] Specifically, the limiting member 41 can be detachably connected to the housing 10 by means of snap-fit, screw connection, etc. The limiting member 41 can be detachably connected to the housing 10 as a separate part, or the limiting member 41 can also be installed on the cover outside the cleaning component 1, and the limiting member 41 can be detachably connected to the housing 10 by the detachable connection between the cover and the housing 10.

[0042] Furthermore, the cleaning component 1 also includes a cover 40 detachably connected to the housing 10, wherein, as Figure 1 and Figure 4 As shown, the housing 10 is provided with a mounting groove 14, and the cover plate 40 is provided with a buckle 43. When the cover plate 40 is installed on the periphery of the first opening 12, the buckle 43 is engaged in the mounting groove 14 so that the cover is fixed on the housing 10.

[0043] It is easy to understand that when the mounting bracket 20 is installed on the housing 10, both the mounting bracket 20 and the roller brush portion 30 will be exposed through the first opening 12 into the receiving cavity 11 and will communicate with the outside. For example... Figures 4-5 As shown, the cover plate 40 has a second opening 42. When the cover plate 40 is closed on the first opening 12, the second opening 42 corresponds to the first opening 12, and the orthographic projection area of ​​the first opening 12 is larger than the orthographic projection area of ​​the second opening 42. Therefore, after the cover plate 40 is closed, the mounting bracket 20 can be blocked by the cover plate 40, leaving only the roller brush part 30 exposed in the receiving cavity 11 through the first opening 12 and the second opening 42, thereby preventing the mounting bracket 20 from accidentally touching and causing the roller brush part 30 to loosen.

[0044] In some embodiments, such as Figure 1 and Figure 4As shown, a limiting member 41 is provided on the cover plate 40. It is easy to understand that the cover plate 40 will only close after the roller brush part 30 is installed into the receiving cavity 11. When the cover plate 40 closes the first opening 12, the limiting member 41 is located on the side of the bracket body 24 away from the output part 13. At this time, the limiting member 41 is in contact with the mounting bracket 20. That is, the housing 10 and the limiting member 41 are clamped on opposite sides of the bracket body 24, thereby preventing the bracket body 24 from sliding relative to the rotation axis 21 along the extension direction of the first axis L1, thereby preventing the roller brush part 30 from jumping during operation.

[0045] In other embodiments, the cover plate 40 can also be rotatably connected to the housing 10 via a pivot. The cover plate 40 can rotate toward the housing 10 so that the cover plate 40 covers the first opening 12, the mounting bracket 20 is blocked by the cover plate 40, the roller brush 30 is exposed through the first opening 12 and the second opening 42 to the receiving cavity 11, and the limiting member 41 prevents the bracket body 24 from sliding. The cover plate 40 can also rotate away from the housing 10 so that the cover plate 40 is away from the first opening 12, the mounting bracket 20 is exposed from the first opening 12, and the bracket body 24 can slide relative to the housing 10.

[0046] Please see Figures 1-2 In some embodiments of this application, the bracket body 24 is provided with a snap-fit ​​part 25, the housing 10 is provided with a slot 15, and the movable trajectory of the bracket body 24 in the extension direction of the first axis L1 has a first preset position and a second preset position.

[0047] like Figure 1 As shown, when the bracket body 24 is in the first preset position, both the bracket body 24 and the roller brush 30 are located in the receiving cavity 11. The transmission part 22 is connected to the output part 13, and the output part 13 can drive the transmission part 22 to rotate. At this time, the locking part 25 engages with the locking groove 15 to lock the bracket body 24 with the housing 10. The transmission part 22 drives the roller brush 30 to rotate relative to the housing 10. The locking of the bracket body 24 with the housing 10 can make the roller brush 30 and the housing 10 relatively stable. When the roller brush 30 rotates, the shaking amplitude between the roller brush 30 and the housing 10 is reduced, the risk of damage to the roller brush 30 is reduced, and the noise generated by the roller brush 30 is also reduced.

[0048] like Figure 2 As shown, when the bracket body 24 is in the second preset position, the transmission part 22 is separated from the output part 13, reducing the rotational interference of the output part 13 on the transmission part 22. At the same time, the snap-fit ​​part 25 is separated from the slot 15, and the bracket body 24 can rotate around the first axis L1 so that the bracket body 24 and the roller brush part 30 leave the receiving cavity 11 through the first opening 12.

[0049] Specifically, when the support body 24 moves from the first preset position to the second preset position, the support body 24 can slide away from the output part 13 along the extension direction of the first axis L1 until the support body 24 slides to the point where the transmission part 22 separates from the output part 13. Then the support body 24 can rotate around the first axis L1, so that the support body 24 and the roller brush part 30 leave the receiving cavity 11 through the first opening 12.

[0050] For example, the output section 13 includes an output gear, and the transmission section 22 is provided with a mating gear on the side facing the output section 13. When the bracket body 24 slides to the point where the transmission section 22 is connected to the output section 13, the mating gear meshes with the output gear, thereby enabling the output section 13 to drive the mating gear to rotate around the second axis L2 through the rotation of the output gear.

[0051] Furthermore, in some embodiments of this application, the mounting bracket 20 further includes a first elastic element (not shown in the figure). The first elastic element is connected to the bracket body 24 and the housing 10. When a force is applied to the bracket body 24, causing the bracket body 24 to be in a second preset position, the bracket body 24 exerts a force on the first elastic element, causing the first elastic element to be in an elastic deformation state (tension deformation or contraction deformation). If the external force on the bracket body 24 disappears, the force exerted by the bracket body 24 on the first elastic element disappears, and the elastic force of the first elastic element causes the bracket body 24 to slide back from the second preset position to the first preset position. The first elastic element can be a spring, which is disposed between the bracket body 24 and the housing 10.

[0052] In some embodiments of this application, the mounting bracket 20 further includes a second elastic element (not shown in the figure) sleeved on the rotating part 23. The second elastic element is connected to the bracket body 24 and the housing 10. When a force is applied to the bracket body 24, causing the bracket body 24 to be outside the receiving cavity 11, the bracket body 24 exerts a force on the second elastic element, causing the second elastic element to be in an elastic deformation state. If the external force on the bracket body 24 disappears, the force exerted by the bracket body 24 on the second elastic element disappears, and the elastic force of the second elastic element causes the bracket body 24 to rotate and return to the receiving cavity 11 from outside the receiving cavity 11. The second elastic element can be a torsion spring, which is sleeved on the rotating shaft 21. One end of the torsion spring is connected to the bracket body 24, and the other end of the torsion spring is connected to the housing 10.

[0053] Please see Figures 5-6In some embodiments of this application, two mounting brackets 20 are provided, and the two mounting brackets 20 are disposed on opposite sides of the roller brush portion 30. The roller brush portion 30 includes a first roller brush 33 and a second roller brush 34, which are arranged at intervals along the extension direction of the second axis L2. The axis of the first roller brush 33 coincides with the axis of the second roller brush 34, and the direction of the axis of the first roller brush 33 / the direction of the axis of the second roller brush 34 is the extension direction of the second axis L2. One end of the first roller brush 33 is mounted on one mounting bracket 20, and the other end of the first roller brush 33 is a free end. One end of the second roller brush 34 is mounted on the other mounting bracket 20, and the other end of the second roller brush 34 is a free end.

[0054] It is easy to understand that there is a first gap between the first roller brush 33 and the second roller brush 34, such as Figure 6 As shown, the two support bodies 24 are the first support body 271 and the second support body 272, respectively. The first roller brush 33 is installed on the first support body 271, and the second roller brush 34 is installed on the second support body 272. The housing 10 may also be provided with a first output part and a second output part. The first output part is used to connect with the first transmission part on the first support body 271, and the second output part is used to connect with the second transmission part on the second support body 272, so as to drive the transmission parts 22 on the two support bodies 24 to rotate respectively.

[0055] Specifically, such as Figure 6 As shown, taking the disassembly of the first roller brush 33 as an example, the first support body 271 is first slid along the extension direction of the first axis L1. That is, the first roller brush 33 moves towards the second roller brush 34. The distance of the first gap along the extension direction of the first axis L1 is greater than the sliding distance of the first roller brush 33 along the extension direction of the first axis L1, so that the first gap can provide movement space for the first roller brush 33 and prevent the second roller brush 34 from interfering with the disassembly process of the first roller brush 33. After the first support body 271 slides to the preset position, the first transmission part separates from the first output part, and the first support body 271 can rotate relative to the housing 10 around the first axis L1, so that the first support body 271 and the first roller brush 33 can rotate away from the receiving cavity 11 through the first opening 12. At this time, the user can remove the first roller brush 33 from the first transmission part, thereby completing the disassembly of the first roller brush 33. The disassembly method of the second roller brush 34 is the same as that of the first roller brush 33, and will not be described in detail here.

[0056] It should be noted that the roller brush section 30 includes two independently detachable split roller brushes, which shortens the overall length of a single roller brush, making it easier to clean. Both the first roller brush 33 and the second roller brush 34 can be provided with spiral bristle structures on their periphery. When the roller brush section 30 sweeps, it picks up hair, causing most of the hair to gather from the outside of the roller brush section 30 towards the gap between the first roller brush 33 and the second roller brush 34. This improves the problem of hair being difficult to clean from various locations on the roller brush section 30, and also makes hair removal on the roller brush section 30 more convenient.

[0057] In some embodiments, the transmission part 22 and the roller brush part 30 can be detachably connected by snap-fit ​​and / or magnetic adsorption. Optionally, the transmission part 22 and the roller brush part 30 can be fixed separately by magnetic adsorption, with one of an iron sheet and a magnet provided on the end of the transmission part 22, and the other of an iron sheet and a magnet provided on the roller brush part 30, and the iron sheet and the magnet are magnetically adsorbed together.

[0058] Optionally, the transmission part 22 and the roller brush part 30 can be separately fixed by snap-fit, specifically, as shown in the example below. Figures 6-7 As shown, the roller brush part 30 has a insertion groove 31 on the side facing the transmission part 22, and the transmission part 22 has an insertion part 26 at the end away from the rotating part 23. The insertion part 26 is inserted into the insertion groove 31 and abuts against the inner wall of the insertion groove 31.

[0059] Further, please see Figures 6-7 The cross-section of the insertion part 26 and the insertion groove 31 along the direction perpendicular to the second axis L2 is square. That is, the insertion groove 31 is a square groove and the insertion part 26 is a square column. When the transmission part 22 is inserted into the insertion groove 31, the square column and the square groove cooperate to prevent the transmission part 22 and the roller brush part 30 from rotating relative to each other around the second axis L2.

[0060] like Figure 8 As shown, the insertion part 26 is provided with a protruding structure 261, and the inner wall of the insertion groove 31 is provided with a stepped structure 32. Specifically, the stepped structure 32 is located on the inner side wall of the square groove, and the protruding structure 261 is located at the end of the square column. When the transmission part 22 is inserted into the insertion groove 31, the square column and the square groove cooperate, and the protruding structure 261 at the end of the square column is engaged with the stepped structure 32 on the inner side wall of the square groove, thereby preventing the roller brush part 30 from disengaging from the transmission part 22 without external force, that is, preventing the roller brush part 30 and the transmission part 22 from sliding relative to each other along the extension direction of the second axis L2.

[0061] Secondly, this application also provides a cleaning device 2, including a main unit 50, a drive assembly, and a cleaning assembly 1 as described in any of the above embodiments. Both the drive assembly and the cleaning assembly 1 are disposed on the main unit 50. The drive assembly is connected to the output portion 13 on the housing 10 of the cleaning assembly 1, and the drive assembly is used to drive the output portion 13 to rotate around a second axis L2. After the roller brush portion 30 is installed in the receiving cavity 11, the drive assembly provides rotational torque to drive the output portion 13 to rotate around the second axis L2. The output portion 13 drives the roller brush portion 30 to rotate around the second axis L2 via the transmission portion 22 on the support body 24, thereby realizing that the drive assembly drives the roller brush portion 30 on the cleaning assembly 1 to rotate. The drive assembly may include a motor for outputting power and a gearbox for speed regulation.

[0062] like Figure 9 As shown, taking a robotic vacuum cleaner as an example, the cleaning device 2 can be installed on the bottom of the main unit 50. When the robotic vacuum cleaner is moving, the cleaning component 1 at the bottom can rotate to perform the sweeping work. Since other parts are provided on both sides of the cleaning component 1 on the robotic vacuum cleaner, the roller brush 30 cannot be disassembled from the sides of the robotic vacuum cleaner. Therefore, in this embodiment, the roller brush 30 is installed by setting a mounting bracket 20. The user can manually adjust the movement of the bracket body 24 relative to the housing 10 so that the roller brush 30 can slide and rotate synchronously with the bracket body 24. This allows the bracket body 24 to drive the roller brush 30 to rotate out of the bottom cavity of the robotic vacuum cleaner, so as to facilitate the disassembly of the roller brush 30. The roller brush 30 can be disassembled and replaced separately without having to be pulled out from the side of the robotic vacuum cleaner.
