Description

Technical Field

[0001] This utility model relates to the field of cleaning technology, specifically to a cleaning component and cleaning equipment. Background Technology

[0002] If the cleaning mechanism remains in constant contact with the ground while the cleaning equipment is in motion, it will accelerate the wear and tear on the cleaning mechanism. Therefore, a lifting mechanism is usually installed on the cleaning equipment to lift the cleaning mechanism off the ground when it is not needed for cleaning operations.

[0003] In existing cleaning equipment, the cleaning mechanism typically undergoes significant horizontal movement during the lifting process. This not only causes the cleaning mechanism to wobble during lifting, affecting the operational stability of the equipment, but also requires a large amount of space to be reserved on the machine body due to the horizontal movement of the cleaning mechanism, thus limiting the compactness of the cleaning equipment's structure. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention provides a cleaning component and cleaning equipment to improve the technical problem that the existing cleaning mechanism is prone to shaking when it is raised and lowered, which affects the operational stability of the cleaning equipment.

[0005] To achieve the above and other related objectives, the present invention provides a cleaning assembly comprising: a first support, a cleaning mechanism, and a first lifting mechanism. The first support includes a first abutment portion; the cleaning mechanism is disposed below the first support and is used to clean the surface to be cleaned; the first lifting mechanism includes a first linkage assembly, a first drive member, and a first cam. The first linkage assembly connects the cleaning mechanism and the first support, and allows the cleaning mechanism and the first support to move closer and further apart; the first drive member is disposed on the cleaning mechanism; the first cam, driven by the first drive member, has a first state of abutting against the first abutment portion and a second state of being separated from the first abutment portion; wherein, in the first state, the cleaning mechanism and the first support are relatively close; and in the second state, the cleaning mechanism can move relatively away from the first support under the action of gravity.

[0006] The beneficial effects of this design are as follows: Because a first linkage assembly is provided between the first support and the cleaning mechanism, when the first drive unit drives the first cam to switch between the first and second states—that is, when the cleaning mechanism is relatively close to or relatively far from the first support—the first linkage assembly can constrain the movement trajectory of the cleaning mechanism through its telescopic operation. This allows the cleaning mechanism to move in a predetermined direction (lifting direction), restricting the horizontal movement of the cleaning equipment and thus guiding the vertical movement of the cleaning mechanism relative to the first support. The guiding effect of the first linkage assembly reduces swaying or deviation of the cleaning mechanism during lifting and lowering, thereby improving the stability of the cleaning equipment. Simultaneously, because the first cam directly abuts against the first supporting part, direct interaction between the first cam and the first support is achieved. This not only simplifies the design structure and improves the overall compactness but also shortens the force transmission path between the cam and the first support, which is beneficial for improving motion efficiency and transmission accuracy. Furthermore, in the second state, the cleaning mechanism can move relatively far from the first support under the influence of gravity. This gravity-based design not only saves energy but also allows the cleaning mechanism to quickly return to the lowered position, thereby improving the cleaning efficiency of the cleaning component.

[0007] In one embodiment of the present invention, the first link assembly includes a first link and a second link that is hinged to the first link. One end of the first link is hinged to the cleaning mechanism and the other end is movably connected to the first bracket. One end of the second link is hinged to the first bracket and the other end is movably connected to the cleaning mechanism.

[0008] The advantages of this design are as follows: The first linkage assembly, by setting up a first link and a second link and hinged them together, forms an approximate scissor-like structure. By controlling the cross angle between the first and second links, the extension and retraction function of the first linkage assembly can be achieved, thereby moving the cleaning mechanism closer to or further away from the first support, thus realizing the lifting and lowering of the cleaning mechanism. This linkage structure has good operational stability, occupies less installation space, and offers high design flexibility. Furthermore, due to the smaller number of parts, its manufacturing cost is also lower.

[0009] In one embodiment of the present invention, the first support includes a first slide groove, the cleaning mechanism includes a second slide groove, one end of the first connecting rod near the first support is slidably connected to the first slide groove and can rotate within the first slide groove; one end of the second connecting rod near the cleaning mechanism is slidably connected to the second slide groove and can rotate within the second slide groove.

[0010] The beneficial effects of this design are as follows: By setting a first sliding groove on the first support and a second sliding groove on the cleaning mechanism, and allowing the first connecting end to slide and rotate within the first sliding groove, and the second lifting end to slide and rotate within the second sliding groove, the horizontal movement of the connecting rod during the telescopic operation of the first connecting rod assembly can be achieved, thereby meeting the telescopic operation requirements of the first connecting rod assembly. This sliding structure design is simple, easy to assemble and maintain, and the sliding groove has a strong load-bearing capacity, resulting in a low failure rate during sliding. This helps reduce the failure rate during the lifting and lowering of the cleaning mechanism, ensuring the cleaning efficiency of the cleaning component.

[0011] In one embodiment of the present invention, the first linkage assembly is disposed on one side of the width direction of the first bracket, and the first cam is disposed on the other side of the width direction of the first bracket. The width direction of the first bracket is consistent with the length of the cleaning mechanism.

[0012] The beneficial effects of this configuration are as follows: When the first support and the cleaning mechanism approach each other, the lifting force generated by the first connecting component on the cleaning mechanism and the abutting force generated by the first cam abutting the first abutting part can be spaced out along the length of the cleaning mechanism. This allows the force distribution on the cleaning mechanism to better adapt to the length requirements of the cleaning mechanism, thereby improving the stability and reliability of the lifting of the cleaning mechanism and reducing the shaking and deviation that occur during the lifting process.

[0013] In one embodiment of the present invention, the first cam includes a first protrusion for abutting against the first abutment, and the first bracket includes an extension that extends toward one side of the cleaning mechanism; the extension is provided with a channel for the first protrusion to enter and exit, and the lower side wall of the channel forms the first abutment.

[0014] The beneficial effects of this design are as follows: By incorporating the first protrusion and the channel, the first protrusion can slide within the channel during the rotation of the first cam, achieving mutual contact with the first abutment. This design creates a relatively stable and reliable contact between the first protrusion and the first abutment, thereby improving the stability of the cleaning mechanism's lifting and lowering operation. Simultaneously, the extension can shorten the height difference between the first abutment and the first cam, thus allowing for a reduction in the design dimensions of the first cam, optimizing its structure, and making it more compact, thereby saving materials and reducing manufacturing costs.

[0015] In one embodiment of the present invention, an opening is provided on one side of the channel for the first protrusion to enter and exit, and a stop is provided on the other side. When the cam is in the first state, the stop forms a stop on the first protrusion in the rotation direction.

[0016] The beneficial effects of this design are as follows: By incorporating a stop within the channel, when the first protrusion enters the channel from the opening, it slides along the first abutment towards the stop as it comes into contact with the first abutment. When the first protrusion comes into contact with the stop, it stops sliding relative to the first abutment, thus maintaining a fixed position relative to it. This design effectively prevents the first protrusion from excessively rotating or dislodging from its predetermined position while in contact with the first abutment, ensuring the stability and reliability of the lifting mechanism during the lifting process.

[0017] In one embodiment of the present invention, the cleaning mechanism is provided with a limiting member. When the first cam is in the second state, the limiting member is located below the first cam and abuts against the first cam.

[0018] The beneficial effects of this design are as follows: By setting a limiting member and having it abut against the first cam, the movement range of the first cam in the second state can be effectively limited, preventing the first cam from moving excessively downward or disengaging from its predetermined position, thereby ensuring the stable operation of the cleaning mechanism. Simultaneously, by setting the limiting member, collisions between the first protrusion and the housing can be avoided, thus better protecting the integrity of the first protrusion and ensuring stable contact between the first protrusion and the first abutting part.

[0019] In one embodiment of the present invention, the first driving member includes a first driving end, and a snap-fit ​​structure is provided between the first driving end and the first cam, wherein the first cam is snap-fitted to the first driving end through the snap-fit ​​structure.

[0020] The beneficial effects of this design are as follows: by setting a snap-fit ​​structure between the first drive end and the first cam, the installation efficiency between the first drive component and the first cam can be improved. Since the snap-fit ​​connection does not require the disassembly and assembly of fasteners, it is more conducive to operation in confined spaces. It also eliminates the need to reserve a large installation space between the cleaning mechanism and the first bracket, which helps to further improve the structural compactness of the cleaning component.

[0021] In one embodiment of the present invention, the snap-fit ​​structure includes a snap-fit ​​groove and a snap-fit ​​post. One of the snap-fit ​​groove and the snap-fit ​​post is disposed on the first cam, and the other is disposed on the first drive end. The snap-fit ​​post is snapped into the snap-fit ​​groove.

[0022] The beneficial effects of this design are as follows: by setting up a snap-fit ​​groove and a snap-fit ​​post, the snap-fit ​​connection between the first drive end and the first cam can be achieved by snapping the two together. This snap-fit ​​structure has a simple manufacturing process and is easy to process, which helps to reduce the processing cost of the snap-fit ​​structure. In addition, it can also improve the reliability and stability of the connection, reduce the risk of the first cam falling off from the first drive end during use, and help to improve the safety of the cleaning equipment operation.

[0023] In one embodiment of the present invention, the cleaning component further includes a second bracket and a second lifting mechanism. The second lifting mechanism connects the second bracket and the cleaning mechanism. The second lifting mechanism works together with the first lifting mechanism to drive the cleaning mechanism to move up and down.

[0024] The beneficial effects of this design are as follows: By incorporating a second lifting mechanism and a second support, the first and second lifting mechanisms work together to distribute the load on the cleaning mechanism, preventing tilting or imbalance caused by unilateral force during lifting. This design ensures smooth operation of the cleaning mechanism during lifting, reducing vibration and swaying, and improving the stability of the cleaning equipment. Furthermore, the inclusion of a first and second support allows for more flexible use of the base support's installation space, further enhancing the overall structural compactness of the cleaning equipment.

[0025] A second aspect of this invention also provides a cleaning device, which includes the cleaning components in any of the above embodiments. Attached Figure Description

[0057] Please see Figures 1 to 25 This utility model provides a cleaning component 100 and a cleaning device 200. The first lifting mechanism 130 provided in the cleaning component 100 can play a guiding role in the lifting process of the cleaning mechanism 110, reduce the horizontal swaying generated by the cleaning mechanism 110 during the lifting process, thereby improving the stability of the operation of the cleaning device 200.

[0058] Please see Figure 1 The cleaning device 200 provided by this utility model includes a body 210 and a cleaning component 100.

[0059] The interior of the body 210 has a storage space to accommodate various components of the cleaning equipment 200. The shape of the body 210 can be arbitrary, such as circular, elliptical, or D-shaped. The cleaning equipment 200 may also include a walking assembly conventionally provided on existing cleaning equipment 200, located below the body 210 to drive the cleaning equipment 200 to achieve self-movement.

[0060] The cleaning component 100 can be detachably connected to the machine body 210. The detachable connection method can be a snap-fit ​​connection, a bolt-fit connection, etc. The number of cleaning components 100 on the cleaning equipment 200 can be one or multiple sets, depending on the cleaning area and efficiency requirements of the cleaning equipment 200. Specifically, in this embodiment, the cleaning equipment 200 is equipped with one set of cleaning components 100, which are installed on the machine body 210 to perform cleaning operations on the surface to be cleaned during the movement of the cleaning equipment 200.

[0061] Please see Figure 2 and Figure 6 In one embodiment of this utility model, the cleaning component 100 includes a first bracket 120, a cleaning mechanism 110, and a first lifting mechanism 130. The first bracket 120 is fixedly connected to the body 210. The first bracket 120 can be directly fixedly connected to the body 210, or it can be connected to the body 210 through other brackets. Optionally, in this embodiment, please refer to... Figure 1 , Figure 3 and Figure 4 The cleaning device 200 also includes a base bracket 220, which is fixedly connected to the body 210 of the cleaning device 200. A first bracket 120 is also fixedly connected to the base bracket 220, thus achieving a fixed connection between the first bracket 120 and the body 210. The first bracket 120 includes a first abutment 121, which can be any structure that meets the abutment requirements, such as a wedge structure or a groove structure, provided on the first bracket 120. Along the height direction of the cleaning device 200, a cleaning mechanism 110 is located below the first bracket 120 and is used to clean the surface to be cleaned. The surface to be cleaned can be, but is not limited to, surfaces or scenes such as the ground, tabletop, glass, and walls. For ease of description, the surface to be cleaned below will be described using the ground as an example.

[0062] It should be noted that when the cleaning equipment 200 is placed on the ground, the main body 210 maintains a fixed height relative to the ground, regardless of whether cleaning is being performed. Correspondingly, the base bracket 220 fixedly connected to the main body 210 also maintains a fixed height relative to the ground; the first bracket 120 fixedly connected to the base bracket 220 also maintains a fixed height relative to the ground.

[0063] Please see Figure 2The cleaning mechanism 110 includes a housing 112 and a cleaning component (not shown in the figure). The cleaning component is rotatably mounted on the housing 112 to perform cleaning operations on the surface to be cleaned. The cleaning component can be a roller brush assembly, a flat mop assembly, a rotary brush assembly, etc. One or more cleaning components can be provided. Optionally, in this embodiment, the cleaning component is a roller brush assembly, and two sets of roller brush assemblies are provided on the housing 112.

[0064] Please see Figures 5 to 7 The first lifting mechanism 130 includes a first linkage assembly 131, a first drive member 132, and a first cam 133. Along the height direction of the cleaning assembly 100 (e.g., ... Figure 6 (As shown on the Z-axis), the first linkage assembly 131 is disposed between the first support 120 and the housing 112, connecting the first support 120 and the housing 112. The first linkage assembly 131 can extend and retract along the height direction of the cleaning assembly 100, so that the cleaning mechanism 110 and the first support 120 are relatively close or far apart. The first linkage assembly 131 can be a scissor-type structure composed of two hinged links, a four-link structure composed of four hinged links, or a foldable or unfoldable linkage structure composed of multiple hinged links to achieve extension and retraction. Since the first support 120 is fixedly connected to the body 210 of the cleaning equipment 200, when the cleaning mechanism 110 and the first support 120 are relatively close, it indicates that the cleaning mechanism 110 is in a raised position and is out of contact with the ground. When the cleaning mechanism 110 and the first support 120 are relatively far apart, it indicates that the cleaning mechanism 110 is in a lowered position and in contact with the ground for normal cleaning operations.

[0065] Please see Figure 5 , Figure 16 and Figure 17 The first driving member 132 is disposed on the cleaning mechanism 110. Specifically, the first driving member 132 is mounted on the housing 112. The first driving member 132 includes a first driving end 1321, and a first cam 133 is connected to the first driving end 1321. When the first driving member 132 operates, it drives the first cam 133 to rotate. The first driving member 132 can be any driving structure capable of driving the first cam 133 to rotate, such as an electric motor or a hydraulic motor. The first cam 133 can be directly connected to the first driving end 1321, or it can be connected through other transmission components (such as gear assemblies, transmission belt assemblies, etc.). Optionally, in this embodiment, the first cam 133 is directly connected to the first driving end 1321. This configuration can achieve higher transmission efficiency and improve transmission accuracy between the first cam 133 and the first driving member 132.

[0066] Please see Figure 5 and Figure 9The first cam 133, driven by the first drive member 132, has a first state in which it abuts against the first abutment portion 121 (e.g., Figure 9 (as shown) and the second state separated from the first abutment 121 (as shown) Figure 5 (As shown). In the first state, the cleaning mechanism 110 and the first support 120 are relatively close to each other, as shown. Figure 10 As shown. In the second state, the cleaning mechanism 110 can move away from the first support 120 relative to each other under the influence of gravity, as... Figure 6 As shown. The first cam 133 can have various structural forms, which are not limited here. For example, the first cam 133 can be a disc cam, a constant-width cam, a cylindrical cam, etc. The first abutting part 121 can abut against the contour surface of the first cam 133 or against other parts of the first cam 133, as long as it ensures that the first cam 133 can switch between the first state and the second state when the first driving member 132 is running.

[0067] It should be noted that the first linkage assembly 131 can be provided in one set or in two sets, depending on the connection stability requirements between the cleaning mechanism 110 and the first support 120. Optionally, in this embodiment, one set of the first linkage assembly 131 is provided, which makes it easier to control the guiding accuracy of the first linkage assembly 131.

[0068] In this embodiment, a first linkage assembly 131 is provided between the first support 120 and the cleaning mechanism 110. When the first drive member 132 drives the first cam 133 to switch between the first state and the second state, that is, when the cleaning mechanism 110 is relatively close to or relatively far from the first support 120, the first linkage assembly 131 can constrain the movement trajectory of the cleaning mechanism 110 through telescopic operation, so that the cleaning mechanism 110 moves in a predetermined direction (lifting direction), restricting the horizontal movement of the cleaning device 200, and thus guiding the vertical movement of the cleaning mechanism 110 relative to the first support 120. The guiding effect of the first linkage assembly 131 can reduce the swaying or deviation of the cleaning mechanism 110 during lifting operation, thereby improving the stability of the cleaning device 200 operation. Meanwhile, since the first cam 133 directly abuts against the first supporting part 121, a direct interaction between the first cam 133 and the first support 120 can be achieved. This not only simplifies the design structure and improves the overall compactness of the structure, but also shortens the force transmission path between the first cam 133 and the first support 120, which is beneficial to improving motion efficiency and transmission accuracy. Furthermore, since in the second state, the cleaning mechanism 110 can move relatively away from the first support 120 under the action of gravity, this gravity-based design not only saves energy but also allows the cleaning mechanism 110 to quickly return to the lowered position, thereby improving the cleaning efficiency of the cleaning component 100.

[0069] Optionally, please refer to Figure 7 and Figure 12 In one embodiment of this utility model, the first link assembly 131 includes a first link 1311 and a second link 1312 that is cross-hinged with the first link 1311. The first link 1311 and the second link 1312 may have the same shape or different shapes. The first link 1311 and the second link 1312 are hinged at the middle by a hinge shaft 1313, forming a cross connection. One end of the first link 1311 is hinged to the cleaning mechanism 110, and the other end is movably connected to the first support 120. This movable connection includes both hinged and sliding connections. One end of the second link 1312 is hinged to the first support 120, and the other end is movably connected to the housing 112 of the cleaning mechanism 110. This movable connection includes both hinged and sliding connections.

[0070] Please see Figure 12 and Figure 18 The first connecting rod 1311 has a first connecting end 13111 and a first lifting end 13112 at its two ends along its length. The first lifting end 13112 is hinged to the housing 112. Specifically, the first lifting end 13112 is a pin structure, and the housing 112 has a first hinge hole 1121, in which the first lifting end 13112 is rotatably connected. The first connecting end 13111 is movably connected to the first bracket 120. The movable connection method is not limited. For example, the first bracket 120 may have a sliding groove, and the first connecting end 13111, being a pin structure, may slide along the sliding groove and rotate within it. Alternatively, the first bracket 120 may have a guide rail, and the first connecting end 13111 may have a slider, which is hinged to the first connecting end 13111 and slides along the guide rail. The second connecting rod 1312 has a second connecting end 13121 and a second lifting end 13122 at both ends along its length. Specifically, the second connecting end 13121 is a pin structure, and the first bracket 120 has a second hinge hole 124, in which the second connecting end 13121 is rotatably connected. The second lifting end 13122 is movably connected to the housing 112. The movable connection method can refer to the movable connection method between the first connecting end 13111 and the first bracket 120, and will not be described again here.

[0071] When the cleaning mechanism 110 approaches the first support 120, the first connecting end 13111 slides relative to the first support 120 toward the side away from the second connecting end 13121, while the second lifting end 13122 slides synchronously relative to the housing 112 toward the side away from the first lifting end 13112. Along the height direction of the cleaning mechanism 110, the first lifting end 13112 moves toward the side closer to the second connecting end 13121, and the second lifting end 13122 moves synchronously toward the side closer to the first connecting end 13111, thereby shortening the first linkage assembly 131 along the height direction of the cleaning device 200. This causes the cleaning mechanism 110, connected to the first lifting end 13112 and the second lifting end 13122, to move upward to approach the first support 120, thus raising the cleaning mechanism 110. When the cleaning mechanism 110 moves away from the first support 120, the first connecting end 13111 slides relative to the first support 120 toward the side closer to the second connecting end 13121, and the second lifting end 13122 slides synchronously relative to the housing 112 toward the side closer to the first lifting end 13112. Along the height direction of the cleaning mechanism 110, the first lifting end 13112 moves away from the second connecting end 13121, and the second lifting end 13122 moves synchronously away from the first connecting end 13111, so as to realize the extension of the first linkage assembly 131 along the height direction of the cleaning equipment, thereby causing the cleaning mechanism 110 to move downward so as to move away from the first support 120, thus realizing the descent of the cleaning mechanism 110.

[0072] In this embodiment, the first linkage assembly 131, by setting a first link 1311 and a second link 1312 and hinged them together, forms an approximate scissor-like structure. By controlling the cross angle between the first link 1311 and the second link 1312, the telescopic function of the first linkage assembly 131 can be realized, thereby driving the cleaning mechanism 110 to move away from or closer to the first support 120, that is, realizing the lifting and lowering of the cleaning mechanism 110. This linkage structure has good operational stability, occupies less installation space, and has high design flexibility. Moreover, due to the small number of parts, its manufacturing cost is also low.

[0073] Optionally, please refer to Figure 7 , Figure 12 , Figure 14 and Figure 18In one embodiment of this utility model, the first support 120 includes a first slide groove 122, and the housing 112 of the cleaning mechanism 110 is provided with a second slide groove 111. The first connecting end 13111 is slidably connected to the first slide groove 122 and can rotate within the first slide groove 122. The second lifting end 13122 is slidably connected to the second slide groove 111 and can rotate within the second slide groove 111. The sliding direction of the first connecting end 13111 in the first slide groove 122 is not limited. In this embodiment, the first slide groove 122 extends along the width direction of the cleaning mechanism 110, that is, the first connecting end 13111 extends along the width direction of the cleaning mechanism 110 (e.g., ...). Figure 6 The first groove 122 slides along the width direction (as shown by the Y-axis). Of course, in other embodiments, the first groove 122 may also extend in other directions, such as along the length direction of the cleaning mechanism 110 (e.g., along the Y-axis). Figure 2 As shown on the X-axis, the first connecting end 13111 slides along the length of the cleaning mechanism 110. The extension direction of the second slide groove 111 is the same as the extension direction of the first slide groove 122, that is, the sliding direction of the second lifting end 13122 in the second slide groove 111 is the same as the sliding direction of the first connecting end 13111 in the first slide groove 122. Specifically, the first connecting end 13111 is a pin structure, which slides in the first slide groove 122 and rotates relative to the first slide groove 122, thereby realizing the sliding and rotation of the first connecting end 13111 in the first slide groove 122. The second lifting end 13122 is also a pin structure, which slides in the second slide groove 111 and rotates relative to the second slide groove 111, thereby realizing the sliding and rotation of the second lifting end 13122 in the second slide groove 111.

[0074] By setting a first slide groove 122 on the first bracket 120 and a second slide groove 111 on the cleaning mechanism 110, and by allowing the first connecting end 13111 to slide and rotate within the first slide groove 122, and the second lifting end 13122 to slide and rotate within the second slide groove 111, the horizontal movement of the connecting rod during the telescopic operation of the first connecting rod assembly 131 can be achieved, thereby meeting the telescopic operation requirements of the first connecting rod assembly 131. This sliding structure design is simple, easy to assemble and maintain, and the slide groove has a strong load-bearing capacity and a low failure rate during sliding, which helps to reduce the failure rate during the lifting and lowering of the cleaning mechanism 110 and ensure the cleaning efficiency of the cleaning component 100.

[0075] Considering that the length of the cleaning mechanism 110 is generally much larger than its width, in order to obtain a more stable lifting force when the first support 120 and the cleaning mechanism 110 approach each other, optionally, please refer to Figure 2 and Figure 5In one embodiment of this utility model, the first connecting rod assembly 131 is disposed on one side of the width direction of the first bracket 120, and the first cam 133 is disposed on the other side of the width direction of the first bracket 120. The width direction of the first bracket 120 is consistent with the length of the cleaning mechanism 110. With this arrangement, when the first bracket 120 and the cleaning mechanism 110 approach each other, the lifting force generated by the first connecting assembly on the cleaning mechanism 110 and the abutting force generated by the first cam 133 abutting against the first abutting part 121 can be spaced apart along the length direction of the cleaning mechanism 110. This allows the force distribution on the cleaning mechanism 110 to better adapt to the length requirements of the cleaning mechanism 110, thereby improving the stability and reliability of the lifting of the cleaning mechanism 110 and reducing swaying and deviation during the lifting process.

[0076] To facilitate the contact between the first cam 133 and the first abutment 121, optionally, please refer to Figure 9 , Figure 13 and Figure 15 In one embodiment of this utility model, the first cam 133 includes a first protrusion 1331 for abutting against the first abutting part 121. The first protrusion 1331 can be a column, a rectangular block, or other structural forms. Optionally, in this embodiment, the first protrusion 1331 is a cylindrical structure. Since the first protrusion 1331 will have a sliding displacement relative to the first abutting part 121 during the abutting process, setting the first protrusion 1331 as a cylindrical structure allows for smooth sliding displacement when it contacts the first abutting part 121, reducing jamming or obstruction, thereby improving the smoothness of the lifting movement of the cleaning mechanism 110.

[0077] Please see Figure 13 The first support 120 includes an extension 123, which extends downwards in the direction of the arrow in the figure, which represents the height direction of the cleaning assembly 100. The extension 123 is provided with a channel 1231 for the first protrusion 1331 to enter and exit, and the lower wall of the channel 1231 forms a first abutment 121. It should be noted that the lower wall of the channel 1231 refers to the bottom wall of the channel 1231 in the height direction of the cleaning equipment 200. The channel 1231 can be a groove structure formed on one side of the extension 123, such as a U-shaped groove structure. The channel 1231 can also be a through-groove structure penetrating the thickness of the extension 123, etc. In actual design and production, it is sufficient to ensure that a stable abutment relationship is formed between the first protrusion 1331 and the first abutment 121 during rotation.

[0078] By providing the first protrusion 1331 and the channel 1231, the first protrusion 1331 can slide within the channel 1231 during the rotation of the first cam 133, thereby achieving mutual contact with the first abutment 121. This design allows for a relatively stable and reliable contact between the first protrusion 1331 and the first abutment 121, thus improving the stability of the lifting operation of the cleaning mechanism 110. Simultaneously, the extension 123 can shorten the height difference between the first abutment 121 and the first cam 133, thereby reducing the design dimensions of the first cam 133, optimizing its structure, making it more compact, and thus saving materials and reducing manufacturing costs.

[0079] Optionally, please refer to Figure 9 and Figure 13 In one embodiment of this utility model, a channel 1231 has an opening 12311 on one side for the first protrusion 1331 to enter and exit, and a stop portion 12312 on the other side. When the first cam 133 is in the first state, the stop portion 12312 provides a stop to the first protrusion 1331 in the rotational direction. The stop portion 12312 can be a wall of the channel 1231 away from the opening 12311, or it can be a block structure separately disposed within the channel 1231. Specifically, in this embodiment, the channel 1231 is an approximately rectangular groove structure. Along the length direction of the rectangular groove structure, one side wall of the rectangular groove is penetrated to form the opening 12311, and the other side wall of the rectangular groove forms the stop portion 12312. Along the width direction of the rectangular groove, the lower wall of the rectangular groove forms a first abutment portion 121.

[0080] By providing a stop 12312 inside the channel 1231, when the first protrusion 1331 enters the channel 1231 from the opening 12311, the first protrusion 1331 slides along the first abutment 121 towards the stop 12312 during the process of abutting against the first abutment 121. When the first protrusion 1331 abuts against the stop 12312, the first protrusion 1331 stops sliding relative to the first abutment 121, thus maintaining a relatively fixed state with respect to the first abutment 121. This design effectively prevents the first protrusion 1331 from excessively rotating or dislodging from its predetermined position while abutting against the first abutment 121, ensuring the stability and reliability of the lifting mechanism during the lifting process.

[0081] In one embodiment of this utility model, please refer to Figure 5The cleaning mechanism 110 is provided with a limiting member 140, which is connected to the housing 112. The limiting member 140 can be integrally formed into the housing 112, such as through injection molding, or it can be fixed to the housing 112 by bolts. The limiting member 140 can be a columnar structure, a rectangular block structure, or other structures. When the first cam 133 is in the second state, that is, when the first cam 133 is separated from the first abutment 121, the limiting member 140 is located below the first cam 133 and abuts against the first cam 133. By providing the limiting member 140 and abutting against the first cam 133, the movement range of the first cam 133 in the second state can be effectively limited, preventing the first cam 133 from moving excessively downward or leaving the predetermined position, thereby ensuring the stable operation of the cleaning mechanism 110. Meanwhile, by setting the limiting member 140, the first protrusion 1331 can be prevented from colliding with the housing 112, which is more conducive to protecting the integrity of the first protrusion 1331 and ensuring stable contact between the first protrusion 1331 and the first abutting part 121.

[0082] To facilitate the connection between the first driving member 132 and the first cam 133, optionally, in one embodiment of this utility model, please refer to... Figures 15 to 17 The first driving component 132 includes a first driving end 1321. A snap-fit ​​structure 150 is provided between the first driving end 1321 and the first cam 133, and the first cam 133 is snap-fitted to the first driving end 1321 through the snap-fit ​​structure 150. The snap-fit ​​structure 150 can have various structural forms. For example, the snap-fit ​​structure 150 can be a pin and pin hole structure, with one of the pin and pin hole located in the first driving end 1321 and the other in the first cam 133. The pin and pin hole achieve the snap-fit ​​connection between the first driving end 1321 and the first cam 133 through the engagement of the pin and pin hole. The snap-fit ​​structure 150 can also be a connector and a slot structure, with one of the connector and slot located at the first drive end 1321 and the other at the first cam 133. The slot can be a polygonal hole structure (such as a square hole or a hexagonal hole) or an irregular hole structure. The connector is inserted into the slot to achieve a snap-fit ​​connection between the first drive end 1321 and the first cam 133. By setting the snap-fit ​​structure 150 between the first drive end 1321 and the first cam 133, the installation efficiency between the first drive component 132 and the first cam 133 can be improved. Since the snap-fit ​​connection does not require the disassembly and assembly of fasteners, it is more conducive to operation in confined spaces. It also eliminates the need to reserve a large installation space between the cleaning mechanism 110 and the first bracket 120, which helps to further improve the structural compactness of the cleaning component 100.

[0083] Optionally, in one embodiment of this utility model, please refer to Figures 15 to 17The snap-fit ​​structure 150 includes a snap-fit ​​groove 151 and a snap-fit ​​post 152. The snap-fit ​​groove 151 is disposed on the first cam 133, and the snap-fit ​​post 152 is disposed on the first drive end 1321. The snap-fit ​​post 152 snaps into the snap-fit ​​groove 151. In other embodiments, the snap-fit ​​groove 151 may be disposed on the first drive end 1321, and the snap-fit ​​post 152 may be disposed on the first cam 133, snapping into the snap-fit ​​groove 151. The snap-fit ​​groove 151 may be a square snap-fit ​​groove, a hexagonal snap-fit ​​groove, or other irregularly shaped snap-fit ​​groove structures. Correspondingly, the structure of the snap-fit ​​post 152 matches the structure of the snap-fit ​​groove 151. Optionally, in this embodiment, the snap-fit ​​groove 151 is an approximately elongated hole structure, and the snap-fit ​​post 152 is an approximately elongated column structure. By setting the snap-fit ​​groove 151 and the snap-fit ​​post 152, the snap-fit ​​connection between the first drive end 1321 and the first cam 133 can be realized. The snap-fit ​​structure 150 has a simple manufacturing process and is easy to process, which helps to reduce the processing cost of the snap-fit ​​structure 150. It can also improve the reliability and stability of the connection, reduce the risk of the first cam 133 falling off from the first drive end 1321 during use, and help to improve the safety of the cleaning equipment 200 operation.

[0084] The cleaning component 100 provided in this utility model, when the cleaning mechanism 110 needs to approach the first support 120, that is, when the cleaning mechanism 110 needs to be lifted and detached from the ground, activates the first drive member 132, which drives the first cam 133 to rotate. During the rotation of the first cam 133, the first protrusion 1331 gradually enters the interior of the channel 1231 from the opening 12311 and abuts against the first abutment 121. Since the height of the first abutment 121 relative to the ground remains fixed, during the abutment between the first protrusion 1331 and the first abutment 121, under the action of the abutment force between the two, the first protrusion 1331 moves upward relative to the ground, thereby generating an upward lifting force on the cleaning mechanism 110, causing the cleaning mechanism 110 to gradually move upward. The first connecting rod assembly 131 shortens synchronously along the height direction of the cleaning device 200 to guide the upward movement of the cleaning mechanism 110. When the first protrusion 1331 abuts against the stop 12312 inside the channel 1231, the first drive member 132 stops running, the first protrusion 1331 stops rotating, the first linkage assembly 131 stops shortening, and the cleaning mechanism 110 stops moving upward and remains in the raised position.

[0085] When the cleaning mechanism 110 needs to move away from the first support 120, that is, when the cleaning mechanism 110 needs to descend and contact the ground, the first drive member 132 moves in the opposite direction, driving the first cam 133 to rotate in the opposite direction. During the rotation of the first cam 133, the first protrusion 1331 gradually separates from the first abutment 121 and eventually disengages from the channel 1231 through the opening 12311. As the abutment force between the first protrusion 1331 and the first abutment 121 disappears, the cleaning mechanism 110 gradually moves downward under its own weight. The first linkage assembly 131 extends synchronously along the height direction of the cleaning device 200 to guide the downward movement of the cleaning mechanism 110. When the first cam 133 abuts against the limiting member 140 outside the channel 1231, the first drive member 132 stops operating, the first cam 133 stops rotating, the first connecting rod assembly 131 stops extending, and the cleaning mechanism 110 stops moving downward and remains in the descending position in contact with the ground. Although the lifting operation of the cleaning mechanism 110 can be achieved by only providing the first lifting mechanism 130 between the cleaning mechanism 110 and the body 210, preferably, in order to further improve the stability of the lifting operation of the cleaning mechanism 110, optionally, in one embodiment of this utility model, please refer to... Figure 2 , Figure 4 , Figure 19 and Figure 20 The cleaning component 100 also includes a second support 160 and a second lifting mechanism 170. The second lifting mechanism 170 connects the second support 160 and the cleaning mechanism 110. The second lifting mechanism 170 works together with the first lifting mechanism 130 to drive the cleaning mechanism 110 to move up and down.

[0086] The second bracket 160 is also fixedly connected to the base bracket 220 to achieve a fixed connection between the second bracket 160 and the body 210. The relative position between the second bracket 160 and the first bracket 120 is not limited; the second bracket 160 and the first bracket 120 can be distributed along the length direction of the cleaning mechanism 110 or along the width direction of the cleaning mechanism 110. The second lifting mechanism 170 can be the same cam-linkage structure as the first lifting mechanism 130, or it can be another lifting structure different from the first lifting mechanism 130, such as a combination of a winch mechanism and a pull rope. Optionally, in this embodiment, the second lifting mechanism 170 is a combination of a cam and a link structure similar to the first lifting mechanism 130.

[0087] Specifically, please refer to Figure 20 and Figure 25The second lifting mechanism 170 includes a second linkage assembly 171, a second drive member 172, and a second cam 173. The second bracket 160 includes a second abutment portion 161. The specific structure of the second linkage assembly 171 can be referred to the relevant description of the first linkage assembly 131 above, and will not be repeated here. The second drive member 172 is a motor, and the second drive member 172 includes a second drive end. The second cam 173 is snap-fitted to the second drive end. The snap-fit ​​connection method can refer to the snap-fit ​​connection method between the first protrusion 1331 and the first drive end 1321 above. The second cam 173 includes a second protrusion 1731. The second protrusion 1731 has a first state of abutting against the second abutment portion 161 under the drive of the second drive member 172 (e.g., Figure 20 (as shown) and the second state separated from the second abutment 161 (as shown) Figure 25 (As shown). In the first state, the cleaning mechanism 110 and the second support 160 are relatively close; in the second state, the cleaning mechanism 110 can move relatively away from the second support 160 under the action of gravity. The specific structure of the second abutment 161 and the mutual movement process between the second protrusion 1731 and the second abutment 161 can be referred to the structural description of the first abutment 121 and the mutual movement process between the first protrusion 1331 and the first abutment 121 in the above embodiments, and will not be repeated here.

[0088] It should be noted that when the cleaning mechanism 110 needs to be lifted, the first lifting mechanism 130 and the second lifting mechanism 170 operate synchronously to ensure that the cleaning mechanism 110 is lifted at the same time.

[0089] By incorporating a second lifting mechanism 170 and a second support 160, the first lifting mechanism 130 and the second lifting mechanism 170 work together to distribute the load on the cleaning mechanism 110, preventing tilting or imbalance caused by unilateral force during lifting. This design ensures that the cleaning mechanism 110 maintains stable operation during lifting, reducing vibration and swaying, and improving the stability of the cleaning equipment 200. Simultaneously, by incorporating the first support 120 and the second support 160, the installation space of the base support 220 can be utilized more flexibly, further enhancing the overall structural compactness of the cleaning equipment 200.

[0090] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
