Description

Technical Field

[0001] This application belongs to the field of cleaning technology, and specifically relates to a cleaning device. Background Technology

[0002] Cleaning equipment, such as robotic vacuum cleaners, is a type of smart home appliance that can automatically clean the floor in a room using a certain amount of artificial intelligence.

[0003] When cleaning equipment is performing edge cleaning, the cleaning component at the bottom of the equipment is a certain distance from the wall, making it difficult for the equipment to effectively clean the dirty area close to the wall. In order to clean the dirty area close to the wall, the relevant technology controls the cleaning component to extend along the length of the cleaning component so that one end of the cleaning component is close to the wall to clean the dirty area.

[0004] However, in related technologies, there is a certain distance between the cleaning components of the cleaning equipment and the rear of the main body of the cleaning equipment. When the cleaning equipment is cleaning, the cleaning components are not easy to fully fit the corner of the wall, which makes the cleaning of the edges not thorough enough, resulting in dead corners for hygiene. Utility Model Content

[0005] The purpose of this application is to provide a cleaning device that can solve the problem of insufficient edge cleaning and the existence of hygiene dead corners in related technologies.

[0006] This application provides a cleaning device, which includes:

[0007] Equipment body;

[0008] A cleaning component is movably disposed at the bottom of the main body of the device;

[0009] A drive mechanism is disposed on the main body of the device. The drive mechanism is connected to the cleaning component and is used to drive the cleaning component to switch between an initial position and an extended position. The direction from the initial position to the extended position intersects both the length direction and the width direction of the cleaning component.

[0010] Specifically, when the cleaning component is in the extended position, in the length direction of the cleaning component, the cleaning component protrudes from the device body or is flush with the edge of the device body, and in the width direction of the cleaning component, the cleaning component protrudes from the device body or is flush with the edge of the device body.

[0011] In this embodiment, the cleaning component can be switched between an initial position and an extended position via a drive mechanism. In the extended position, the cleaning component protrudes beyond the device body or is flush with its edge in both length and width directions. This arrangement shortens the distance between the cleaning component and the tail of the device body, allowing the component to be closer to or flush with the tail of the device body. This enables the cleaning component to get closer to wall edges and corners. When the cleaning device is near a wall or corner, the cleaning component can more fully contact these hard-to-clean areas, effectively removing dirt and grime close to walls and corners, significantly reducing the residue in hard-to-reach areas, and greatly improving the thoroughness of cleaning, thus effectively enhancing the overall cleaning effect.

[0026] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0027] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0028] The cleaning equipment provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0029] refer to Figures 1-7 The cleaning device provided in this application embodiment may include a device body 100, a cleaning component 200, and a drive mechanism 300.

[0030] like Figure 1 As shown, the cleaning component 200 is movably disposed at the bottom of the device body 100, and the drive mechanism 300 is disposed on the device body 100. The drive mechanism 300 can be connected to the cleaning component 200 and can be used to drive the cleaning component 200 to switch between the initial position and the extended position.

[0031] Among them, such as Figure 7 As shown, when the cleaning component 200 is in the extended position, the cleaning component 200 protrudes from the device body 100 or is flush with the edge of the device body 100 in the length direction, and the cleaning component 200 protrudes from the device body 100 or is flush with the edge of the device body 100 in the width direction.

[0032] Here, the direction from the initial position to the extended position can intersect both the length direction and the width direction of the cleaning component 200. For example, the direction from the initial position to the extended position can be a diagonally rearward direction of the device body 100, allowing the cleaning component 200 to move diagonally rearward of the device body 100, thereby shortening the distance between the cleaning component 200 and the tail of the device body 100. In this embodiment, the angle between the direction from the initial position to the extended position and the length direction of the cleaning component 200 is less than 90°. Optionally, the angle between the direction from the initial position to the extended position and the length direction of the cleaning component 200 can be 67°; of course, the angle between the direction from the initial position to the extended position and the length direction of the cleaning component 200 can also be less than or greater than 67°.

[0033] In one configuration, the cleaning component 200 can move linearly from its initial position to its extended position. This configuration allows a single drive mechanism 300 to move the cleaning component 200 between the initial and extended positions, simplifying the structure of the cleaning equipment. In another configuration, the cleaning component 200 can first move along its length, so that it protrudes beyond the device body 100 or is flush with its edge. Then, it can move further along its width, so that it protrudes beyond the device body 100 or is flush with its edge. This configuration requires two drive mechanisms 300 to drive the cleaning component 200's movement in both the length and width directions, respectively.

[0034] In this embodiment, the driving mechanism 300 can drive the cleaning component 200 to switch between an initial position and an extended position. When in the extended position, the cleaning component 200 can protrude from the device body 100 in both its length and width directions, or be flush with the edge of the device body 100. This arrangement shortens the distance between the cleaning component 200 and the tail of the device body 100, allowing the cleaning component 200 to be closer to or flush with the tail of the device body 100. This enables the cleaning component 200 to get closer to wall edges and corners, making it easier for it to fully conform to the corners. When the cleaning device is close to walls or corners, the cleaning component 200 can more fully contact these hard-to-clean areas, effectively removing dirt close to walls and corners, greatly reducing the residue in hard-to-clean areas, significantly improving the thoroughness of cleaning, and thus effectively enhancing the overall cleaning effect.

[0035] In an optional embodiment of this application, the cleaning component 200 is vertically and vertically connected to the drive mechanism 300. This configuration allows the cleaning component 200 to be raised during cleaning when encountering items that should not be wetted, such as carpets, to prevent direct contact between the cleaning component 200 and the carpets or other items. When cleaning ordinary floors, the cleaning component 200 can be lowered to clean the floor. This allows the cleaning equipment to adapt to different cleaning scenarios, thereby improving the efficiency and convenience of cleaning work.

[0036] In other embodiments, the cleaning component 200 and the drive mechanism 300 may also be connected in a non-liftable manner.

[0037] In optional embodiments, such as Figure 1 , Figure 5 and Figure 6 As shown, the cleaning equipment may also include a guide member 400, to which the cleaning component 200 can be vertically connected. The guide member 400 can be connected to the drive mechanism 300, meaning the cleaning component 200 can be vertically connected to the drive mechanism 300 via the guide member 400. This configuration facilitates the lifting and lowering of the cleaning component 200 compared to a direct vertical connection between the cleaning component 200 and the drive mechanism 300. Alternatively, the cleaning equipment may not include the guide member 400, in which case the cleaning component 200 can be directly vertically connected to the drive mechanism 300.

[0038] The main body 100 of the equipment may be provided with a limiting part (not shown in the figure). When the cleaning component 200 is in the initial position, the cleaning component 200 is limited and engaged with the limiting part in the direction from the extended position to the initial position. The drive mechanism 300 can drive the guide member 400 to move in the direction from the extended position to the initial position, thereby causing the cleaning component 200 to rise. In this embodiment, the limiting part prevents the cleaning component 200 from continuing to move horizontally. The drive mechanism 300 continues to drive the guide member 400 to move in the direction from the extended position to the initial position, which can convert the horizontal movement of the cleaning component 200 into upward movement, thereby realizing the rising of the cleaning component 200. With this configuration, there is no need to set up an additional lifting drive structure to control the lifting and lowering of the cleaning component 200. The lifting and lowering of the cleaning component 200 can be realized by relying only on the drive mechanism 300 and the guide member 400 in cooperation with the limiting part, which can effectively simplify the structure of the cleaning equipment and help reduce manufacturing costs.

[0039] In other embodiments, the main body 100 of the device may not be provided with a limiting part, and the cleaning device may also include a lifting drive structure, which can be connected to the cleaning component 200 and used to drive the cleaning component 200 to lift.

[0040] In optional embodiments, such as Figure 6 As shown, one of the guide member 400 and the cleaning component 200 may be provided with a guide groove 410, and the other may be provided with a guide post 250. The guide post 250 and the guide groove 410 can be slidably connected. The guide groove 410 can be inclined, and its extension direction intersects the vertical direction and the horizontal direction. In this embodiment, the guide groove 410 is inclined and intersects the vertical and horizontal directions. When the guide post 250 slides in the guide groove 410, the movement trajectory of the guide post 250 is decomposed into horizontal and vertical movements. Since the cleaning component 200 is limited by the limiting part, the limiting part restricts the cleaning component 200 from continuing to move horizontally. Therefore, when the guide member 400 continues to move, the relative sliding between the guide groove 410 and the guide post 250 will cause the cleaning component 200 to produce a vertical displacement, thereby realizing the lifting function of the cleaning component 200. Meanwhile, the inclined guide groove 410 eliminates the need for an additional lifting drive structure for the lifting movement of the cleaning component 200; the lifting of the cleaning component 200 can be achieved solely by the inclined direction of the guide groove 410, thus simplifying the structure of the cleaning equipment. Furthermore, the sliding connection between the guide groove 410 and the guide column 250, which connects the guide member 400 to the cleaning component 200, reduces the swaying of the cleaning component 200 during movement and lifting.

[0041] Of course, the guide groove 410 and guide post 250 may not be provided on either the guide member 400 or the cleaning component 200. For example, the guide member 400 and the cleaning component 200 can be connected by a pull rod or a pull rope. After the cleaning component 200 moves to the initial position, the guide member 400 can continue to move in the direction from the extended position to the initial position. At this time, the guide member 400 can drive the cleaning component 200 to rise by pulling the rod or the pull rope.

[0042] Optionally, such as Figure 6 As shown, there are at least two guide grooves 410 and at least two guide posts 250. Each guide groove 410 is spaced apart along the direction from its extended position to its initial position, and each guide post 250 is also spaced apart along the same direction. Each guide groove 410 corresponds one-to-one with each guide post 250. This arrangement connects the cleaning component 200 and the guide member 400 through at least two guide posts 250 and guide grooves 410, improving the connection stability between the cleaning component 200 and the guide member 400, reducing swaying and tilting of the cleaning component 200 during movement, and distributing the forces acting on the cleaning component 200 during movement to different connection points through at least two guide posts 250 and at least two guide grooves 410, thus helping to ensure the force balance of the guide member 400.

[0043] Of course, the number of guide grooves 410 can also be one, and the number of guide posts 250 can also be one.

[0044] In some embodiments, such as Figure 2 , Figures 4-6 As shown, the cleaning component 200 may be provided with a connecting part 240, such as... Figure 5 and Figure 6 As shown, the guide member 400 may be provided with a connecting cavity 430, and at least a portion of the connecting part 240 may be located within the connecting cavity 430. This configuration allows the connecting cavity 430 to limit the connection part 240, preventing the cleaning component 200 from shifting or shaking during movement.

[0045] Of course, the guide member 400 may not have the connecting cavity 430, and the connecting part 240 may be located on one side of the guide member 400.

[0046] Here, one of the guide groove 410 and the guide post 250 can be disposed on the cavity wall of the connecting cavity 430, and the other can be disposed on the connecting part 240. This arrangement facilitates the connection between the cleaning component 200 and the guide member 400. On the other hand, the sliding fit between the guide groove 410 and the guide post 250 can further limit the connection part 240, thereby further preventing the cleaning component 200 from shifting or shaking during movement.

[0047] Of course, one of the guide groove 410 and the guide post 250 may not be provided on the cavity wall of the connecting cavity 430, and the other may not be provided on the connecting part 240.

[0048] Optionally, such as Figures 4-6 As shown, each of the two opposing cavity walls of the connecting cavity 430 is provided with one of a guide groove 410 and a guide post 250, and each of the two opposing sides of the connecting portion 240 is provided with the other of a guide groove 410 and a guide post 250. Each guide post 250 is slidably connected to its corresponding guide groove 410. This arrangement improves the connection stability between the connecting portion 240 and the guide member 400. Furthermore, when the cleaning assembly 200 is subjected to lateral forces, the cooperation between each guide post 250 and its corresponding guide groove 410 can effectively disperse and bear these lateral forces, preventing the connecting portion 240 from lateral displacement or offset within the connecting cavity 430, thus making the cleaning assembly 200 less prone to offset or shaking during movement. For example, as... Figure 4As shown, a connecting hole 241 may be provided on the connecting part 240, and the guide post 250 may be connected to the connecting hole 241. In some embodiments, the guide post 250 may be a screw, the connecting hole 241 may be a threaded hole, the screw shank may pass through the guide groove 410 and be threaded into the connecting hole 241, and in order to prevent the guide post 250 from coming out of the guide groove 410, the diameter of the head of the guide post 250 is greater than the width of the guide groove 410.

[0049] In this embodiment, as Figure 6 As shown, guide grooves 410 can be provided on both opposite cavity walls of the connecting cavity 430, such as... Figure 4 and Figure 5 As shown, guide posts 250 can be provided on both opposite sides of the connecting portion 240. Of course, guide posts 250 can also be provided on both opposite cavity walls of the connecting cavity 430, and guide grooves 410 can also be provided on both opposite sides of the connecting portion 240.

[0050] Of course, it is also possible that only one cavity wall of the connecting cavity 430 is provided with a guide groove 410, and a guide post 250 is provided on one side of the connecting part 240.

[0051] In optional embodiments, such as Figure 2 and Figure 3 As shown, the main body 100 of the device may be provided with a slide groove 130, the extension direction of which is parallel to the direction from the initial position to the extended position, and the cleaning component 200 may be slidably connected to the slide groove 130. This configuration can provide clear guidance for the movement of the cleaning component 200 and prevent the cleaning component 200 from deviating or shaking during movement.

[0052] Of course, the main body of the equipment 100 may not have the slide 130.

[0053] Optionally, the limiting part described above may include the groove wall of the slide 130 in the direction from the extended position to the initial position. Here, the length of the slide 130 may be less than the travel of the guide 400, so that after the cleaning component 200 reaches the initial position, the guide 400 can still move in the direction from the extended position to the initial position, thereby driving the cleaning component 200 to rise.

[0054] like Figures 4-6As shown, the cleaning component 200 is provided with a connecting part 240, which is connected to the drive mechanism 300. In the vertical direction, the orthographic projection of the connecting part 240 is offset from the orthographic projection of the center of the cleaning component 200 in the length direction. This arrangement ensures that, on the one hand, when the cleaning component 200 moves to its initial position, it is located directly below the main body 100 of the equipment, preventing one end of the cleaning component 200 from extending beyond the edge of the main body 100; on the other hand, it prevents the connecting part 240 from interfering with other components of the cleaning equipment and provides more installation space for other components.

[0055] Of course, in the vertical direction, the orthographic projection of the connecting part 240 can also coincide with the orthographic projection of the center of the cleaning component 200.

[0056] In optional embodiments, such as Figures 1-3 As shown, the drive mechanism 300 may include a lead screw 330, a lead screw nut 340, and a drive motor 310. The lead screw 330 can be rotatably connected to the main body 100 of the equipment. The lead screw 330 can be parallel to the direction from the extended position to the initial position. The lead screw nut 340 can be threadedly connected to the lead screw 330 and can be connected to the cleaning component 200. The drive motor 310 can be connected to the lead screw 330 and is used to drive the lead screw 330 to rotate. In this embodiment, the drive motor 310 can precisely control the rotation speed of the lead screw 330 according to the cleaning needs, thereby controlling the moving speed of the cleaning component 200, thus ensuring the cleaning effect. Furthermore, the movement of the cleaning component 200 is achieved by driving the lead screw 330 to rotate through the drive motor 310, which has a simple structure and is easy to maintain. Here, the cleaning component 200 can be connected to the lead screw nut 340 through a guide member 400.

[0057] Of course, the drive mechanism 300 may also include a cylinder, a hydraulic cylinder, or other structures capable of linear movement.

[0058] Optionally, such as Figures 1-3 As shown, the drive mechanism 300 may further include a transmission assembly 320, through which the drive mechanism 300 is connected to the lead screw 330. In this embodiment, the transmission assembly 320 can be flexibly designed according to the spatial structure of the cleaning equipment, and the relative position and transmission direction between the drive motor 310 and the lead screw 330 can be changed so that the positions of the drive motor 310 and the lead screw 330 can adapt to the spatial structure of the cleaning equipment, thereby preventing interference between the drive motor 310 and the lead screw 330 and other components of the cleaning equipment.

[0059] Further optional, such as Figures 1-3As shown, the transmission assembly 320 may include a first gear 321 and a second gear 322 meshing with the first gear 321. The first gear 321 is coaxially connected to the output shaft of the drive motor 310, and the second gear 322 is coaxially connected to the lead screw 330. The diameter of the first gear 321 is larger than the diameter of the second gear 322. This configuration causes the second gear 322 to rotate faster than the output shaft of the drive motor 310, thereby increasing the rotational speed of the lead screw 330. The drive motor 310 drives the first gear 321 to rotate, which in turn drives the second gear 322 to rotate. The second gear 322 then drives the lead screw 330 to rotate. The rotation of the lead screw 330 causes the lead screw nut 340 to translate along the axial direction of the lead screw 330, which in turn drives the guide member 400 to translate. The guide member 400, via the guide post 250, causes the cleaning assembly 200 to extend from its initial position to its extended position to the rear of the device body 100.

[0060] In this embodiment, the drive mechanism 300 can be disposed within the device body 100, and, as... Figure 3 As shown, two spaced-apart fixed seats 140 can be provided on the base plate 110 of the main body 100 of the equipment, and the two ends of the lead screw 330 can be rotatably connected to the two fixed seats 140 respectively.

[0061] like Figure 1 As shown, a motor mounting bracket 150 can also be provided on the base plate 110. The motor mounting bracket 150 can be located near the rear side wall 120 of the main body 100, and the drive motor 310 is mounted on the motor mounting bracket 150.

[0062] Optionally, such as Figure 5 and Figure 6 As shown, the guide member 400 may be provided with a nut fixing part 440, which can be connected to the lead screw nut 340. The nut fixing part 440 can be parallel to the base plate 110, and the nut fixing part 440 and the base plate 110 can be vertically locked together. On the one hand, the base plate 110 can provide a certain support for the guide member 400, and on the other hand, it can prevent the guide member 400 from rotating in the circumferential direction of the lead screw 330. Further optionally, the guide member 400 may be provided with a folded edge 420 on the side away from the nut fixing part 440. The folded edge 420 can fit against the base plate 110 so that the guide member 400 and the base plate 110 are locked together in the circumferential direction of the lead screw 330, thereby further preventing the guide member 400 from flipping or shaking during movement.

[0063] In optional embodiments, such as Figure 4As shown, the cleaning assembly 200 may include a connecting bracket 210, a roller brush assembly 220, and a squeegee assembly 230. Both the roller brush assembly 220 and the squeegee assembly 230 are connected to the connecting bracket 210, and the length direction of the roller brush assembly 220 and the length direction of the squeegee assembly 230 are parallel. The connecting bracket 210 can be connected to the connecting part 240. Here, the roller brush assembly 220 is used to clean dust, stains, or debris on the floor, and the squeegee assembly 230 can remove debris and wastewater from the floor, thereby preventing debris and wastewater residue and improving the cleaning effect of the cleaning equipment.

[0064] Of course, the cleaning component 200 may also include other cleaning structures, such as a flatbed mop component.

[0065] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
