Description

Technical Field

[0001] This application relates to the field of cleaning technology, and more specifically, to a cleaning organization and cleaning equipment. Background Technology

[0002] Cleaning equipment includes robotic vacuum cleaners, vacuum cleaners, and multi-functional cleaning base stations. Most cleaning equipment is equipped with a cleaning mechanism, which is used to clean up external garbage and collect it into the cleaning equipment.

[0003] Cleaning mechanisms typically include a housing and a cleaning component. The housing has a mounting cavity in which the cleaning component is rotatably mounted. However, existing cleaning components may cause damage or soiling to the actuator when the actuator (e.g., a user or a robotic arm) assembles or disassembles the cleaning component. Utility Model Content

[0004] The main objective of this application is to provide a cleaning mechanism and cleaning equipment to at least solve the problem in the prior art where cleaning components cause damage to or soiling of the execution body.

[0005] According to one aspect of this application, a cleaning facility is provided, comprising:

[0006] case;

[0007] A cleaning component, comprising a cleaning assembly and a connecting assembly, wherein the cleaning assembly is rotatably and detachably mounted on the housing via the connecting assembly;

[0008] The connecting component is provided with at least two force-bearing parts, which are spaced apart along the outer periphery of the connecting component. The at least two force-bearing parts are used for the execution body to clamp the connecting component so as to install the cleaning component onto the housing or to remove the cleaning component from the housing.

[0009] Furthermore, the force-bearing part includes at least one of a force-bearing plane and a force-bearing concave surface.

[0010] Furthermore, at least one of the force-bearing parts includes a first force-bearing plane, and at least another force-bearing part includes a second force-bearing plane. The first force-bearing plane is disposed on the outer surface of a first side of the connecting component, and the second force-bearing plane is disposed on the outer surface of a second side of the connecting component opposite to the first side.

[0011] Furthermore, the included angle A between the first force-bearing plane and the second force-bearing plane satisfies the relationship: 30°≤A≤180°.

[0012] Furthermore, a first locking portion is provided on the outer periphery of the first side of the connecting component, the first force-bearing plane is provided on the first locking portion, and a second locking portion is provided on the housing to cooperate with the first locking portion. The first locking portion has a first position to lock the connecting component in the housing by cooperating with the second locking portion, and a second position to release the connecting component by separating from the second locking portion.

[0013] Wherein, the first force-bearing plane is subjected to an external force to cause the first locking part to switch between the first position and the second position.

[0014] Furthermore, the first locking part includes:

[0015] A support segment is connected to the connecting assembly and is reciprocating in a direction away from the connecting assembly. Along a first direction, the support segment has a first plane on the side away from the connecting assembly.

[0016] The control section is disposed on the first plane, and the control section is provided with the first force-bearing plane on the side opposite to the connecting component, and the first force-bearing plane is connected to the first plane.

[0017] The angle B between the first force-bearing plane and the first plane satisfies the following relationship: 50°≤B≤120°.

[0018] Furthermore, the second side of the connecting component is provided with a second force-bearing plane, and a first limiting part is provided on the second force-bearing plane. The housing is provided with a second limiting part that cooperates with the first limiting part. The connecting component has a third position where it rotates along a first rotation direction to a position where the first limiting part cooperates with the second limiting part, and a fourth position where it rotates along a second rotation direction opposite to the first rotation direction to a position where the first limiting part separates from the second limiting part.

[0019] When the connecting component rotates to the third position, the first force-bearing plane is subjected to an external force, causing the first locking part to switch between the first position and the second position.

[0020] Furthermore, the first limiting part has a second plane connected to the second force-bearing plane, and the included angle C between the second force-bearing plane and the second plane satisfies the relationship: 45°≤C≤135°.

[0021] Furthermore, the maximum length L1 of the first force-bearing plane along the second direction and the maximum width W1 of the first force-bearing plane along the third direction satisfy the following relationship: 1.67 ≤ L1 / W1 ≤ 5.00; the maximum length L1 of the first force-bearing plane satisfies the following relationship: 10mm ≤ L1 ≤ 15mm; and the maximum width of the first force-bearing plane satisfies the following relationship: 3mm ≤ W1 ≤ 6mm; and / or,

[0022] The maximum length L2 of the second force-bearing plane along the second direction and the maximum width W2 of the second force-bearing plane along the fourth direction satisfy the following relationship: 0.83 ≤ L2 / W2 ≤ 1.20; the maximum length L1 of the second force-bearing plane satisfies the following relationship: 5mm ≤ L2 ≤ 6mm; the maximum width of the second force-bearing plane satisfies the following relationship: 5mm ≤ W2 ≤ 6mm; and / or,

[0023] The maximum length L1 of the first force-bearing plane is less than or equal to the maximum length L2 of the second force-bearing plane; and / or,

[0024] The cleaning component further includes a seal, which is disposed between the cleaning component and the connecting component, and the projection surface of the seal protrudes from the projection surface of the connecting component in the axial direction of the cleaning component.

[0025] On the other hand, this application also provides a cleaning device, which includes the above-mentioned cleaning mechanism.

[0026] Compared to existing technologies, this application features at least two force-bearing portions spaced apart along the outer periphery of the connecting component. This means that the executing entity can apply force to the connecting component through at least two force-bearing portions. For example, when installing or disassembling the connecting component, if the executing entity is a hand, the operator can apply force to the two force-bearing portions with two fingers to facilitate the installation and disassembly of the connecting component. Furthermore, since the force-bearing portions are located on the connecting component, the executing entity does not need to contact the cleaning component when installing or disassembling the connecting component, thereby preventing the cleaning component from damaging or soiling the executing entity to a certain extent.

[0042] The existing cleaning component 30, after being installed on the housing 10, typically requires screws, bolts, or other fasteners to secure it to the housing 10. This makes installing or removing the cleaning component 30 from the housing 10 time-consuming and laborious.

[0043] See Figures 1 to 9 As shown, according to an embodiment of this application, a cleaning device is provided, the cleaning device including a cleaning mechanism, the cleaning mechanism including: a housing 10, a cleaning component 30 and a locking component 40.

[0044] The cleaning component 30 includes a cleaning assembly 31 and a connecting assembly 32. The cleaning assembly 31 is rotatably and detachably mounted on the housing 10 via the connecting assembly 32. The locking assembly 40 includes a first locking part 41 and an elastic part 42. The first locking part 41 is disposed on the connecting assembly 32, and the elastic part 42 is disposed between the connecting assembly 32 and the first locking part 41. The first locking part 41 is movably disposed along the inward and outward directions of the connecting assembly 32. A second locking part 101 is provided on the housing 10. The first locking part 41 has a first position where it engages with the second locking part 101 to lock the cleaning component 30 under external force, and a second position where it disengages from the second locking part 101 to unlock the cleaning component 30. The elastic part 42 is at least used to apply a spring force to the first locking part 41 along the inward and outward directions of the connecting assembly 32.

[0045] Specifically, in this embodiment, when installing the cleaning component 31, the first locking part 41 on the moving connecting component 32 is moved along the direction from the inside to the outside of the connecting component 32. When the first locking part 41 reaches the first position that engages with the second locking part 101, the connecting component 32 and the cleaning component 31 are locked onto the housing 10. When it is necessary to remove the cleaning component 30 from the housing 10, an external force is applied to the first locking part 41. When the external force on the first locking part 41 can overcome the elastic force applied to the first locking part 41 by the elastic part 42, the first locking part 41 moves along the direction from the outside to the inside of the connecting component 32, and the first locking part 41 disengages from the second locking part 101. At this time, the cleaning component 30 is unlocked from the housing 10, so that the cleaning component 30 can be removed.

[0046] It is understood that, through the provision of the elastic part 42, the first locking part 41, and the second locking part 101 in this embodiment, the cleaning component 30 can be quickly assembled and disassembled from the housing 10, thereby improving the assembly efficiency of the housing 10 and the cleaning component 30. Furthermore, thanks to the provision of the elastic part 42, when the external force applied to the first locking part 41 is less than the elastic force applied by the elastic part 42 to the first locking part 41, the first locking part 41 will not switch from the first position to the second position, preventing the first locking part 41 from being subjected to other external forces transmitted from the cleaning device during operation, thus avoiding the cleaning component 30 from detaching from the cleaning device. In this embodiment, the elastic part 42 can be a spring or elastic rubber.

[0047] Furthermore, the first locking part 41 includes a support section 411 and a locking section 412. The support section 411 is movably disposed on the connecting assembly 32 along the inward and outward directions, and the side of the support section 411 near the connecting assembly 32 abuts against the first end of the elastic part 42. The locking section 412 is connected to the side of the support section 411 opposite to the connecting assembly 32. When the locking section 412 is subjected to an external force, it moves toward the side opposite to the connecting assembly 32 to cooperate with the second locking part 101, thereby placing the first locking part 41 in a first position.

[0048] In this embodiment, the support section 411 is used to improve the structural strength of the first locking part 41, preventing excessive internal stress in the first locking part 41, which could easily lead to damage. The locking section 412 is used to cooperate with the second locking part 101 to lock the cleaning component 30 onto the housing 10. Specifically, during the assembly of the cleaning component 30, the support section 411 moves away from the connecting assembly 32. When the first locking part 41 reaches the first position, the locking section 412 cooperates with the second locking part 101, thereby locking the cleaning component 30 onto the housing 10. When it is necessary to disassemble the cleaning component 30, the support section 411 is controlled to overcome the external force applied by the elastic part 42, so that the support section 411 moves towards the connecting assembly 32. When the first locking part 41 reaches the second position, the locking section 412 disengages from the second locking part 101, at which point the cleaning component 30 can be removed from the housing 10. In some embodiments, the support section 411 and the locking section 412 are integrally formed.

[0049] In some embodiments, the second locking portion 101 includes a slot. Optionally, the locking section 412 includes a locking protrusion protruding from the support section 411.

[0050] Specifically, the second locking part 101 is a slot on the side of the housing 10 near the cleaning component 30, and the locking section 412 is a locking protrusion. When the first locking part 41 moves to the first position, the locking protrusion passes through the slot, thereby improving the fixing effect of the locking assembly on the cleaning component 30.

[0051] In other embodiments, the second locking portion 101 may also be a latching protrusion protruding along the direction close to the connecting component 32, and the locking section 412 has a groove on the side near the second locking portion 101, so that the cleaning component 30 is locked by the cooperation of the latching protrusion and the groove. Of course, the second locking portion 101 may also be configured as a first magnetic attractor, and the locking section 412 may be provided with a second magnetic attractor or a metal layer on the side near the second locking portion 101.

[0052] Furthermore, the connecting component 32 is provided with a guide portion 322, which extends inward and outward along the connecting component 32. A first locking portion 41 is movably disposed on the guide portion 322, and a first end of an elastic portion 42 abuts against the first locking portion 41, while a second end of the elastic portion 42 abuts against the guide portion 322. In this embodiment, the guide portion 322 defines the movement direction of the support section 411 and the locking section 412. That is, when an external force is applied to the support section 411 or the locking section 412, the support section 411 or the locking section 412 can only move along the two ends extending from the guide portion 322. At the same time, the guide portion 322 also makes the direction of the elastic force applied by the elastic portion 42 to the first locking portion 41 almost consistent with the extension direction of the guide portion 322. Optionally, the guide portion 322 can be a groove or a guide rail.

[0053] Furthermore, a first limiting portion 321 is provided on the outer periphery of the second side of the connecting assembly 32, and a second limiting portion 102 is provided on the housing 10 to cooperate with the first limiting portion 321. The connecting assembly 32 has a third position where it rotates along a first rotation direction to cooperate with the first limiting portion 321 and the second limiting portion 102, and a fourth position where it rotates along a second rotation direction opposite to the first rotation direction to separate the first limiting portion 321 and the second limiting portion 102. When the connecting assembly 32 rotates to the third position, the first locking portion 41 is switched between the first position and the second position by an external force.

[0054] It is understandable that if the cleaning component 30 is fixed to the housing 10 solely by the first locking part 41, the second locking part 101, and the elastic part 42, the connecting component 32 may be subjected to external forces during the operation of the cleaning equipment, causing it to shake. Therefore, in this embodiment, a first limiting part 321 is provided on the outer periphery of the second side of the connecting component 32, and a second limiting part 102 is provided on the housing 10. When the first limiting part 321 and the second limiting part 102 cooperate, the first locking part 41 and the second locking part 101 cooperate to increase the force support point of the connecting component 32 and the housing 10, thereby preventing the connecting component 32 from shaking. Simultaneously, when assembling the cleaning component 30, first place the cleaning component 30 on the housing 10, then rotate the connecting assembly 32 in the first rotation direction. When the first limiting part 321 on the connecting assembly 32 rotates to the third position where it engages with the second limiting part 102, the first locking part 41 can be moved to the first position, thereby locking the cleaning component 30 onto the connecting assembly. To disassemble the cleaning component 30, first move the first locking part 41 to the second position, at which point the cleaning component 30 can move. Then rotate the connecting assembly 32 in the second rotation direction to separate the first limiting part 321 from the second limiting part 102, releasing the limiting effect of the second limiting part 102 on the cleaning component 30. Finally, the cleaning component 30 can be removed from the housing 10. In other words, when assembling or disassembling the cleaning component 30, simply control the first locking part 41 to switch between the first and second positions and control the rotation of the connecting assembly 32 to quickly assemble or disassemble the cleaning component 30.

[0055] In some embodiments, the first limiting portion 321 includes a first limiting protrusion that protrudes in a direction away from the connecting component 32, and the second limiting portion 102 includes a second limiting protrusion that protrudes in a direction close to the connecting component 32. When the first limiting portion 321 moves to the third position, the first limiting protrusion abuts against the second limiting protrusion.

[0056] To further enhance the limiting effect on the cleaning component 30 and prevent the connecting assembly 32 from shaking on the housing 10 during operation of the cleaning equipment, in this embodiment, a third limiting portion 323 is provided on the outer periphery of the first side of the connecting assembly 32 opposite to the second side. A locking component 40 is disposed on the third limiting portion 323, and the housing 10 is provided with a fourth limiting portion 103 that cooperates with the third limiting portion 323. When the first limiting portion 321 cooperates with the second limiting portion 102, the third limiting portion 323 can cooperate with the fourth limiting portion 103. When the first limiting portion 321 separates from the second limiting portion 102, the third limiting portion 323 can separate from the fourth limiting portion 103.

[0057] It is understandable that the arrangement of the first limiting part 321, the second limiting part 102, the third limiting part 323, and the fourth limiting part 103 not only improves the stability of the cleaning component 30 on the housing 10, but also provides a certain positioning effect during the assembly of the cleaning component 30. That is, when the connecting assembly 32 rotates along the first rotation direction, the first limiting part 321 engages with the second limiting part 102, and the third limiting part 323 engages with the fourth limiting part 103, indicating that the cleaning component 30 is now limited on the housing 10. The cleaning component 30 can be locked on the housing 10 by moving the first locking part 41 to engage with the second locking part 101. In this embodiment, the third limiting part 323 includes a third limiting protrusion that protrudes in a direction away from the first side, and the fourth limiting part 103 includes a limiting groove. When the connecting assembly 32 is rotated so that the third limiting protrusion passes through the limiting groove, the first limiting protrusion abuts against the second limiting protrusion. In some embodiments, the second locking part 101 may be the inner wall surface of the limiting groove or a slot provided on the inner wall surface of the limiting groove.

[0058] After the cleaning component 30 is installed on the housing 10, there may be a certain gap between the connecting component 32 and the housing 10. When the cleaning equipment is running, the gap may cause the connecting component 32 to be displaced in the radial direction of the cleaning component 31. Therefore, in this embodiment, at least three support limiting parts 60 are provided between the housing 10 and the connecting component 32. The at least three support limiting parts 60 are spaced apart along the circumferential direction of the connecting component 32 to limit the radial displacement of the connecting component 32 along the cleaning component 31.

[0059] Specifically, in this embodiment, at least three support and limiting portions 60 are provided between the housing 10 and the connecting assembly 32. When the connecting assembly 32 is displaced radially, the at least three support and limiting portions 60 can provide support and limitation in the circumferential direction of the connecting assembly 32, preventing the connecting assembly 32 from shaking or shifting in the radial direction of the cleaning assembly 31. In addition, the multiple spaced support and limiting portions 60 can evenly distribute the supporting force, thereby better limiting the radial displacement of the connecting assembly 32.

[0060] In some embodiments, three support limiting portions 60 are provided between the housing 10 and the connecting assembly 32. The first support limiting portion 60 is formed between the first limiting portion 321 and the second limiting portion 102. The second support limiting portion 60 is formed between the first locking portion 41 and the second locking portion 101. A first receiving groove 104 is provided on the housing 10, and the connecting assembly 32 is disposed in the first receiving groove 104. The bottom surface of the first receiving groove 104 and the outer peripheral surface of the connecting assembly 32 form a third support limiting portion 60. The bottom surface of the first receiving groove 104 is located between the second locking portion 101 and the second limiting portion 102.

[0061] In some embodiments, the first limiting portion 321 includes a first limiting protrusion, and the second limiting portion 102 includes a second limiting protrusion. The contact surfaces of the first limiting protrusion and the second limiting protrusion form a first supporting limiting portion 60. Alternatively, the second limiting portion 102 can be the inner wall surface of the first receiving groove 104 near the first limiting protrusion, and the contact point or contact surface between this inner wall surface and the first limiting protrusion forms the first supporting limiting portion 60. In some embodiments, the first locking portion 41 includes a locking protrusion, and the second locking portion 101 includes a slot. The contact point or contact surface between the locking protrusion and the slot forms a second supporting limiting portion 60. In some embodiments, a raised surface is provided on the outer peripheral surface of the first receiving groove 104, and the raised surface contacts the outer peripheral surface of the connecting component 32, forming a third supporting limiting portion 60. Optionally, a raised surface is provided on the outer peripheral surface of the connecting component 32. The raised surface contacts the bottom surface of the first receiving groove 104, and the raised surface forms a third support limiting part 60. Optionally, the raised surface can also be a protrusion.

[0062] Furthermore, a shock-absorbing pad is provided between the connecting component 32 and the housing 10.

[0063] It is understood that, due to the possible gap between the connecting component 32 and the housing 10, relative vibration between the connecting component 32 and the housing 10 may occur during the operation of the cleaning equipment. Therefore, in this embodiment, a shock-absorbing pad is provided between the connecting component 32 and the housing 10 to prevent vibration from easily damaging the connecting component 32 or the housing 10. In some embodiments, a shock-absorbing pad is provided on the outer surface of the connecting component 32 relative to the bottom surface of the first receiving groove 104, or a shock-absorbing pad is provided on the bottom surface of the first receiving groove 104. In some embodiments, a shock-absorbing pad is provided on at least one of the first limiting protrusion and the second limiting protrusion. In some embodiments, a shock-absorbing pad is provided on at least one of the first locking part 41 and the second locking part 101.

[0064] Furthermore, the cleaning mechanism also includes a cover 20, which covers the housing 10, and a connecting component 32 is located between the cover 20 and the housing 10, with a gap between the connecting component 32 and the cover 20.

[0065] Specifically, in this embodiment, the cover 20 is used to improve the protective performance of the cleaning component 30. In some existing technologies, the cleaning component 30 needs to be covered by the cover 20 onto the connecting assembly 32 to be fixed between the housing 10 and the cover 20; that is, there is no gap between the cover 20 and the connecting assembly 32, and the cover 20 needs to apply a resisting force to the connecting assembly 32. In this embodiment, due to the provision of the first locking part 41, the second locking part 101, and the elastic part 42, the cleaning component 30 can be fixed to the housing 10 without the cover 20 applying a resisting force. Simultaneously, in this embodiment, when the connecting assembly 32 is installed between the cover 20 and the housing 10, there is a gap between the connecting assembly 32 and the cover 20. This gap is a reserved space that acts as a buffer, preventing thermal expansion of the connecting assembly 32 and thus preventing damage to the cover 20 or the connecting assembly 32.

[0066] Furthermore, the housing 10 is provided with a first receiving groove 104 and a second receiving groove 105 that are interconnected. The first receiving groove 104 is disposed on one side of the second receiving groove 105. The cleaning component 31 is disposed in the first receiving groove 104, and the connecting component 32 is disposed in the second receiving groove 105. The cleaning mechanism also includes a sealing element 70, which is disposed in the second receiving groove 105 and located between the connecting component 32 and the cleaning component 31. The sealing element 70 abuts against the housing 10 and the cover 20.

[0067] Specifically, since the cleaning component 31 may cause dust, sewage or other impurities to enter the receiving groove during cleaning, the housing 10 of this embodiment is provided with a first receiving groove 104 and a second receiving groove 105, and the connecting component 32 is disposed in the second receiving groove 105. The sealing member 70 is disposed between the connecting component 32 and the cleaning component 31, and the sealing member 70 abuts between the housing 10 and the cover 20, thereby preventing dust, sewage or other impurities from entering the second receiving groove 105 and causing pollution or impact on the connecting component 32.

[0068] In existing connecting components 32, the connecting component 32 is typically an annular sleeve, meaning that the outer circumferential surface of the annular sleeve is a convex arc surface. When the actuator operates on the annular sleeve, it is easy to cause slippage. Therefore, it is necessary to apply force to the cleaning component 31 to control the connecting component 32.

[0069] Furthermore, the connecting component 32 is provided with at least two force-bearing parts 50, which are spaced apart along the outer periphery of the connecting component 32. The at least two force-bearing parts 50 are used for the execution body to clamp the connecting component 32 so as to install the cleaning component 30 onto the housing 10 or to remove the cleaning component 30 from the housing 10.

[0070] In this embodiment, since at least two force-bearing portions 50 are provided at intervals along the outer periphery of the connecting component 32, the executing body can apply force to the connecting component 32 through at least two force-bearing portions 50. For example, when it is necessary to install or remove the connecting component 32, the operator can apply force to the two force-bearing portions 50 with two fingers to facilitate the installation and removal of the connecting component 32. Furthermore, since the force-bearing portions 50 are provided on the connecting component 32, the executing body does not need to contact the cleaning component 31 when installing or removing the connecting component 32, thereby avoiding damage or soiling of the executing body by the cleaning component 31 to a certain extent.

[0071] In existing connecting components 32, the outer peripheral surface of the connecting component 32 is usually a force-bearing convex surface. This causes the actuator to slip easily when applying external force to the force-bearing convex surface, making it difficult for the actuator to operate the connecting component 32. In this embodiment, the force-bearing part 50 includes at least one of a force-bearing plane and a force-bearing concave surface.

[0072] It is understandable that when the actuator is a finger, the contact area between the finger and the force-bearing plane and the force-bearing concave surface is significantly larger than the contact area between the finger and the force-bearing convex surface. This makes it less likely for the finger to slip when operating the connecting component 32, thus making it easier for the actuator to operate the connecting component 32. In some embodiments, the force-bearing concave surface includes a concave arc surface or a concave toothed groove surface.

[0073] Furthermore, the locking component 40 is disposed on the outer periphery of the first side of the connecting component 32, and a first force-bearing plane 4131 is provided on the locking component 40. A second force-bearing plane 324 is provided on the outer periphery of the second side of the connecting component 32 opposite to the first side. The first force-bearing plane 4131 and the second force-bearing plane 324 are used for the execution body to clamp the connecting component 32 so as to install the cleaning component 30 on the housing 10 or to remove the cleaning component 30 from the housing 10.

[0074] Specifically, the presence of a first force-bearing plane 4131 and a second force-bearing plane 324 provides a clear point of force application for the executing entity. Furthermore, in this embodiment, since the first force-bearing plane 4131 and the second force-bearing plane 324 are respectively located on the outer periphery of the first side of the connecting component 32 and on the locking component 40, a certain distance exists between them. This facilitates the executing entity clamping the connecting component 32 using the first force-bearing plane 4131 and the second force-bearing plane 324, preventing them from getting too close and making it difficult for the executing entity to apply clamping force to the connecting component 32. Of course, in some other embodiments, the force-bearing part 50 may also include multiple force-bearing planes or multiple force-bearing concave surfaces, spaced apart, so that the executing entity can clamp different force-bearing planes according to different situations.

[0075] As attached Figure 7 As shown, the included angle A between the first force-bearing plane 4131 and the second force-bearing plane 324 satisfies the relationship: 30°≤A≤180°.

[0076] It is known that when the angle A between the first force-bearing plane 4131 and the second force-bearing plane 324 is too small, for example, A is less than 30°, it may cause the actuator to have difficulty applying force to the first force-bearing plane 4131 and the second force-bearing plane 324. For example, if the actuator is two fingers, the two fingers may come into contact with each other when applying force to the two planes with a small angle. When the angle between the first force-bearing plane 4131 and the second force-bearing plane 324 is too large, for example, A is greater than 180°, it may cause the actuator to have difficulty clamping the connecting component 32 through the first force-bearing plane 4131 and the second force-bearing plane 324. For example, if the actuator is two fingers, even when the two fingers are at their maximum opening angle, they may not be able to clamp the first force-bearing plane 4131 and the second force-bearing plane 324 at the same time. When the value of A is within the above range, the actuator can more easily clamp and apply force to the first force-bearing plane 4131 and the second force-bearing plane 324. The value of A can be 30°, 60°, 90°, 120°, 150°, or 180°.

[0077] Furthermore, the first force-bearing plane 4131 is disposed on the first locking part 41, and the first force-bearing plane 4131 is subjected to external force to switch the first locking part 41 between the first position and the second position.

[0078] It is understandable that, since the first force-bearing plane 4131 is disposed on the first locking part 41, when the first locking part 41 is in the first position, applying an external force to the first force-bearing plane 4131 causes the first locking part 41 to move in the direction closer to the connecting component 32, and eventually move to the second position. Conversely, applying an external force to the first force-bearing plane 4131 causes the first locking part 41 to move in the direction away from the connecting component 32, and eventually move the first locking part 41 to the second position.

[0079] Furthermore, along the first direction, the support segment 411 has a first plane 4111 on the side away from the connecting assembly 32. The first locking part 41 includes a control segment 413, which is disposed on the first plane 4111, and a first force-bearing plane 4131 is disposed on the side of the control segment 413 away from the connecting assembly 32, and the first force-bearing plane 4131 is connected to the first plane 4111. The included angle B between the first force-bearing plane 4131 and the first plane 4111 satisfies the relationship: 50°≤B≤120°.

[0080] Understandably, when the value of B is between 50° and 90°, the angle between the first force-bearing plane 4131 and the first plane 4111 is acute or right, providing a certain space between them. This allows the finger to easily rest between the two planes, and the planes provide some support for the finger. When the value of B is between 90° and 120°, the first force-bearing plane 4131 does not obstruct the finger, allowing the finger to apply a greater force. If the value of B is less than 50°, the space between the two planes is smaller, making it difficult for the finger to apply force. When the value of B is greater than 120°, the finger is prone to slipping when applying force to the first force-bearing plane 4131. The value of B can be 50°, 60°, 70°, 80°, 90°, 100°, 110°, or 120°.

[0081] Furthermore, a second force-bearing plane 324 is provided on the second side of the connecting component 32, and a first limiting part 321 is provided on the second force-bearing plane 324. The first limiting part 321 has a second plane 3211 connected to the second force-bearing plane 324, and the included angle C between the second force-bearing plane 324 and the second plane 3211 satisfies the relationship: 45°≤C≤135°.

[0082] Similar to the first force-bearing planes 4131 and 4111, when the value of C is between 45° and 90°, there is a certain space between the second force-bearing plane 324 and the second plane 3211, allowing fingers to grip the second force-bearing plane 324. When the value of C is between 90° and 135°, the fingers can apply a large gripping force to the second force-bearing plane 324, and the fingers are less likely to slip on the second force-bearing plane 324. However, when C is less than 45°, the space between the second force-bearing plane 324 and the second plane 3211 may be too small, allowing the fingers to grip the second force-bearing plane 324 through this space. When C is greater than 135°, the fingers may easily slip when gripping the second force-bearing plane 324. The value of C can be 45°, 55°, 65°, 75°, 85°, 95°, 105°, 115°, 125°, and 135°.

[0083] Furthermore, the maximum length L1 of the first force-bearing plane 4131 along the second direction and the maximum width W1 of the first force-bearing plane 4131 along the third direction satisfy the following relationship: 1.67≤L1 / W1≤5.00.

[0084] When L1 / W1 is greater than 5, this results in a large difference between the width-to-length ratio of the maximum length L1 and the maximum width W1 of the first force-bearing plane 4131, thus affecting the bending stiffness of the first force-bearing plane 4131. That is, when the actuator applies a large pressure to the first force-bearing plane 4131, it may cause the first force-bearing plane 4131 to bend. Simultaneously, an excessively large aspect ratio of the first force-bearing plane 4131 will require the first locking part 41 to be longer or wider, reducing its seismic resistance. Conversely, when L1 / W1 is less than 1.67, it is inconvenient for the actuator to apply force to the first force-bearing plane 4131. For example, if the actuator is a finger, the L1 / W1 ratio should be set to fit the length of the finger. In this embodiment, the value of L1 / W1 can be 1.67, 2, 2.5, 3, 3.5, 4, 4.5, and 5.

[0085] Furthermore, in some embodiments, in order to conform to the force applied by the finger to the first force-bearing plane 4131, the maximum length L1 of the first force-bearing plane 4131 satisfies the relationship: 10mm≤L1≤15mm, and the maximum width of the first force-bearing plane 4131 satisfies the relationship: 3mm≤W1≤6mm.

[0086] When L1 and W1 satisfy the above relationship, the finger can fit as closely as possible to the first force-bearing surface 4131, increasing the contact area between the finger and the first force-bearing surface 4131, and making it easier for the finger to apply force to the first force-bearing surface 4131, thereby preventing the finger from slipping on the first force-bearing surface 4131. The value of L1 can be 10mm, 11mm, 12mm, 13mm, 14mm, and 15mm. The value of W1 can be 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, and 6mm.

[0087] In some embodiments, the maximum length L2 of the second force-bearing plane 324 along the second direction and the maximum width W2 of the second force-bearing plane 324 along the fourth direction satisfy the following relationship: 0.83≤L2 / W2≤1.20.

[0088] Similar to the first force-bearing plane 4131, the ratio between the maximum length L2 and the maximum width W2 of the second force-bearing plane 324 should not be too large or too small. However, considering that when operating the connecting component 32, the thumb is typically used to contact the first force-bearing plane 4131, while the index finger is used to contact the second force-bearing plane 324, and since the surface area of ​​the index finger is smaller than that of the thumb, the ratio between the maximum length L2 and the maximum width W2 of the second force-bearing plane 324 can be closer in this embodiment. The value of L2 / W2 can be 0.83, 0.9, 1.0, 1.1, or 1.2.

[0089] In some embodiments, the maximum length L1 of the second force-bearing plane 324 satisfies the relationship: 5mm≤L2≤6mm, and the maximum width of the second force-bearing plane 324 satisfies the relationship: 5mm≤W2≤6mm.

[0090] Similarly, considering that the index finger is typically used to contact the second force-bearing surface 324, the maximum length and maximum width of the second force-bearing surface 324 can be reduced compared to the first force-bearing surface 4131. The value of L2 can be 5mm, 5.2mm, 5.4mm, 5.6mm, 5.8mm, or 6mm. The value of W2 can be 5mm, 5.2mm, 5.4mm, 5.6mm, 5.8mm, or 6mm.

[0091] Furthermore, the maximum length L1 of the first force-bearing plane 4131 is less than or equal to the maximum length L2 of the second force-bearing plane 324.

[0092] Understandably, in some embodiments where the executing entity is a finger, the arrangement of the first force-bearing plane 4131 and the second force-bearing plane 324 needs to be designed according to ergonomics. That is, the thumb is used to grip the first force-bearing plane 4131, and the index finger is used to grip the second force-bearing plane 324. In this case, the maximum length L1 of the first force-bearing plane 4131 should be greater than the maximum length L2 of the second force-bearing plane 324. However, in some embodiments where the executing entity is not a finger but a robotic hand, the two grippers of the robotic hand are usually designed identically. In this embodiment, the maximum length L1 of the first force-bearing plane 4131 and the maximum length of the second force-bearing plane 324 need to be designed to be the same so that the robotic hand can apply the same force to the first force-bearing plane 4131 and the second force-bearing plane 324.

[0093] Furthermore, on the projection of the cleaning component 31 along its axial direction, the projection surface of the seal 70 protrudes beyond the projection surface of the connecting component 32.

[0094] Specifically, in this embodiment, the seal 70 acts as a stop, that is, when the connecting component 32 is disassembled or assembled onto the housing 10, since the projection surface of the seal 70 protrudes from the projection surface of the connecting component 32 in the axial direction of the cleaning component 31, the execution body will not come into contact with the cleaning component 31 under the action of the seal 70, thereby preventing the cleaning component 31 from damaging or soiling the execution body.

[0095] In some embodiments, the connecting component 32 is disposed at one end of the cleaning component 31 along its axial direction, and the end of the cleaning component 31 opposite to the connecting component 32 is a free end. Optionally, the connecting component 32 may include two sets, with the two sets of connecting components 32 respectively disposed at the ends of the cleaning component 31 along its axial direction.

[0096] In summary, the cleaning mechanism and equipment of this application, through the design of the first locking part 41, the elastic part 42, and the second locking part 101, apply external force to the first locking part 41, thereby enabling the cleaning component 30 to be quickly installed on or quickly removed from the housing 10. Furthermore, by providing a first limiting part 321 and a third limiting part 323 on the connecting assembly 32, and a second limiting part 102 and a fourth limiting part 103 on the housing 10, and by rotating the connecting assembly 32 so that when the first limiting part 321 engages with the second limiting part 102, the third limiting part 323 engages with the fourth limiting part 103 simultaneously, thereby preventing the connecting assembly 32 from shaking on the housing 10 to a certain extent. In addition, at least three supporting limiting parts 60 are provided between the connecting assembly 32 and the housing 10 to further prevent the connecting assembly 32 from shaking radially on the housing 10 during operation of the cleaning equipment. Furthermore, a shock-absorbing pad is provided between the connecting component 32 and the housing 10 to improve the shock resistance of the cleaning mechanism. On the other hand, the connecting component 32 of this application is provided with at least two force-bearing parts 50, which are used by the execution body to clamp the connecting component 32 to install the cleaning component 30 onto or remove the cleaning component 30 from the housing 10. This means that the execution body can apply force to the connecting component 32 through at least two force-bearing parts 50. For example, when it is necessary to install or remove the connecting component 32, the operator can use two fingers to apply force to the two force-bearing parts 50 respectively to facilitate the installation and removal of the connecting component 32. Moreover, since the force-bearing parts 50 are located on the connecting component 32, the execution body does not need to contact the cleaning component 31 when installing or removing the connecting component 32, thereby preventing the cleaning component 31 from damaging or soiling the execution body to a certain extent. Finally, a seal 70 is provided between the connecting component 32 and the cleaning component 31. On the projection of the connecting component 32 along its axial direction, the projection surface of the seal 70 protrudes from the projection surface of the connecting component 32. The seal 70 further separates the connecting component 32 and the cleaning component 31.

[0097] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures.
