[0026] This application proposes a cleaning device 10, which can be used for cleaning floors or windows. For example, the cleaning device 10 may include a cleaning robot for cleaning floors, wherein the cleaning robot may include a sweeping robot, a mopping robot, or a sweeping and mopping robot, etc., without limitation.
[0027] Please refer to Figure 1 and Figure 2 The cleaning device 10 includes: a main unit 1 and a cleaning module 3.
[0028] The cleaning module 3 is connected to the host 1. The cleaning module 3 is used to abut against the surface to be cleaned (not shown in the figure), and the host 1 is used to drive the cleaning module 3 to move along the first direction X to clean the surface to be cleaned. The surface to be cleaned can be the ground, and the first direction X is the forward direction of the cleaning device 10.
[0029] The cleaning module 3 can be a sweeping module, a mop, a mop board, etc., and there is no limitation here.
[0030] Please refer to the reference image; cleaning equipment 10 (e.g.) Figure 1 The cleaning device 10 also includes: a connection component 2, which is connected to the main unit 1 (e.g., Figure 1 The main unit 1 is connected to the cleaning module 3, which is connected to the connecting component 2 and is used to abut against the surface to be cleaned. The main unit 1 is adapted to push the cleaning module 3 to move along the first direction X through the connecting component 2.
[0031] Understandably, when the cleaning device 10 moves along the first direction X, the main unit 1 drives the connecting component 2 to move, and the connecting component 2 drives the cleaning module 3 to move synchronously, thereby achieving linkage between the cleaning module 3 and the main unit 1. Specifically, the connecting component 2 pushing the cleaning module 3 means that the connecting component 2 applies a pushing force to the cleaning module 3. Under this pushing force, the connecting component 2 applies downward pressure to the cleaning module 3, allowing the cleaning module 3 to better contact the surface to be cleaned, thus reducing the problem of the cleaning module 3 lifting off the surface and increasing the contact area between the cleaning module 3 and the surface to be cleaned, thereby improving the cleaning effect.
[0032] For example, the main unit 1 is located below the cleaning module 3, and the surface to be cleaned is located below the cleaning module 3 (e.g., Figure 2 (Below the cleaning module 3 in the middle), the connecting component 2 is connected between the host 1 and the cleaning module 3.
[0033] When the host 1 pushes the cleaning module 3 along the first direction X through the connecting component 2, the first direction X is parallel to the surface to be cleaned. The connecting component 2 applies a pushing force to the cleaning module 3 that intersects with the surface to be cleaned, and the direction of the force is inclined downward. It can be understood that the inclined downward force can be decomposed into a horizontal component and a vertical component. The direction of the horizontal component is the same as the first direction X, and the direction of the vertical component is downward. In this way, the horizontal component allows the cleaning module 3 to move along the first direction X, while the vertical downward component will squeeze the cleaning module 3 towards the surface to be cleaned, so as to increase the downward pressure of the cleaning module 3, so that the cleaning module 3 can better contact the surface to be cleaned, thereby reducing the problem of the cleaning module 3 lifting off the top, and increasing the contact area between the cleaning module 3 and the surface to be cleaned, thereby improving the cleaning effect.
[0034] Wherein, the extension direction of connecting component 2 intersects with the first direction X, please refer to Figure 3 Please refer to the extension direction of connecting component 2. Figure 3The extension line L in the diagram. It is understood that the direction of the thrust is usually the same as the extension direction of the connecting component 2. In this application, the extension direction of the connecting component 2 intersects with the first direction X, so that the direction of the thrust applied by the connecting component 2 to the cleaning module 3 intersects with the first direction X. That is, the connecting component 2 applies a thrust to the cleaning module 3 that intersects with the surface to be cleaned, so that the cleaning module 3 can move along the first direction X under the action of the thrust. At the same time, it can increase the downward pressure between the cleaning module 3 and the surface to be cleaned, thereby increasing the contact area between the cleaning module 3 and the surface to be cleaned to improve the cleaning effect.
[0035] The end of the cleaning module 3 closest to the first direction X is the front end, and the end of the cleaning module 3 furthest from the first direction X is the rear end. The distance from the intersection of the extension direction of the connecting component 2 and the cleaning module 3 to the rear end is less than the distance from the intersection of the extension direction of the connecting component 2 and the cleaning module 3 to the front end.
[0036] It should be noted that the intersection of the extension direction of the connecting component 2 and the cleaning module 3 can fall inside the cleaning module 3 or outside the cleaning module 3, as long as the distance from the intersection of the extension direction of the connecting component 2 and the cleaning module 3 to the rear end is less than the distance from the intersection of the extension direction of the connecting component 2 and the cleaning module 3 to the front end. No restrictions are imposed here.
[0037] This ensures that the intersection of the extension direction of the connecting component 2 and the cleaning module 3 falls near the rear end of the cleaning module 3, allowing the thrust to act more directly on the rear half of the cleaning module 3, thereby reducing the problem of the cleaning module 3 lifting off the rear.
[0038] For example, the center of gravity of cleaning module 3 is located between the front and rear ends, and the intersection of the extension direction of connecting component 2 and cleaning module 3 is located at the center of gravity of cleaning module 3 (e.g., Figure 3 Point A in the diagram is located on the side away from the first direction X. The intersection of the extension direction of the connecting component 2 and the cleaning module 3 refers to the point where the thrust acts on the cleaning module 3 in the extension direction of the connecting component 2. This intersection point is set on the side of the center of gravity of the cleaning module 3 away from the first direction X so that the thrust can act more directly on the rear half of the cleaning module 3, thereby reducing the problem of the cleaning module 3 lifting off the tail.
[0039] According to the cleaning device 10 provided in the embodiments of this application, the extension direction of the connecting component 2 intersects with the first direction X, and the distance from the intersection of the extension direction of the connecting component 2 and the cleaning module 3 to the rear end is less than the distance from the intersection of the extension direction of the connecting component 2 and the cleaning module 3 to the front end. In this way, when the connecting component 2 pushes the cleaning module 3 to move along the first direction X, the connecting component 2 can apply a thrust to the rear half of the cleaning module 3 to reduce the problem of the cleaning module 3 lifting off the ground, and can increase the downward pressure between the cleaning module 3 and the ground, as well as increase the contact area between the cleaning module 3 and the surface to be cleaned, thereby improving the cleaning effect.
[0040] In some implementations, the cleaning module 3 is detachably installed on the connecting component 2 to facilitate the removal and replacement of the cleaning module 3. The cleaning module 3 and the connecting component 2 can be connected by bolts, snap-fit, or other detachable methods, which are not limited here.
[0041] In some embodiments, the intersection of the extending direction of the connecting component 2 and the cleaning module 3 falls within the cleaning module 3. This allows the connecting component 2 to be positioned closer to the cleaning module 3, resulting in a more compact arrangement of the connecting component 2 and the cleaning module 3.
[0042] In some embodiments, please refer to Figure 3 In the first direction X, the cleaning module 3 includes a first part 31 and a second part 32 connected together, the first part 31 and the second part 32 being located at the center of gravity of the cleaning module 3 (e.g., Figure 3 On both sides of point A in the diagram, the first part 31 is located on the side of the second part 32 closer to the first direction X, and the connecting component 2 is connected to the second part 32.
[0043] In this way, when the host 1 pushes the cleaning module 3 to move along the first direction X through the connecting component 2, the connecting component 2 mainly applies a thrust to the rear end of the cleaning module 3 to reduce the problem of the rear end of the cleaning module 3 lifting off the ground, and can increase the downward pressure between the cleaning module 3 and the ground, as well as increase the contact area between the cleaning module 3 and the surface to be cleaned, thereby improving the cleaning effect.
[0044] In some embodiments, at least a portion of the connecting component 2 has its orthographic projection onto the cleaning module 3 falling within the cleaning module 3. Therefore, the gravity of the portion of the connecting component 2 located above the cleaning module 3 can be used to apply a certain downward pressure to the cleaning module 3, thereby further increasing the downward pressure between the cleaning module 3 and the ground, and increasing the contact area between the cleaning module 3 and the surface to be cleaned, thus improving the cleaning effect.
[0045] It is understood that when the cleaning device 10 is placed on a horizontal plane, the orthographic projection of at least a portion of the connecting component 2 onto the cleaning module 3 refers to the projection of the connecting component 2 onto the cleaning module 3 in the vertical direction.
[0046] For example Figure 3 As shown, the connecting component 2 is located above the second part 32, and at least a portion of the connecting component 2 is projected onto the cleaning module 3 within the second part 32, meaning that at least a portion of the connecting component 2 is located above the second part 32. In this way, the gravity of the portion of the connecting component 2 located above the second part 32 can be used to apply a certain downward pressure to the second part 32, thereby further increasing the downward pressure between the cleaning module 3 and the ground, and increasing the contact area between the cleaning module 3 and the surface to be cleaned, thereby improving the cleaning effect.
[0047] In some embodiments, please refer to Figure 3 The cleaning device 10 also includes a connector 4, which is connected to the main unit 1 (e.g., Figure 1 The main unit 1) is detachably connected, and the connecting component 2 includes at least one link 21, one end of which is connected to the connecting seat 4 and the other end is connected to the cleaning module 3, and the extension direction of at least one link 21 intersects the first direction X.
[0048] Therefore, the connecting rod 21 can be connected to the main unit 1 through the connecting seat 4. Since the connecting seat 4 is detachably connected to the main unit 1, the cleaning module 3 can be separated from the main unit 1 by separating the main unit 1 and the connecting seat 4, thereby reducing the difficulty of disassembling the cleaning module 3. Furthermore, the connecting rod 21 is connected between the connecting seat 4 and the cleaning module 3, so that the connecting rod 21 is not directly connected to the main unit 1, which facilitates the replacement and maintenance of the connecting rod 21, thereby reducing the maintenance difficulty of the connecting rod 21.
[0049] Please refer to Figure 3 The extension direction of the connecting rod 21 intersects the first direction X, so that the direction of the thrust applied by the connecting rod 21 to the cleaning module 3 intersects the first direction X. That is, the connecting rod 21 applies a thrust to the cleaning module 3 that intersects with the surface to be cleaned, so that the cleaning module 3 can move along the first direction X under the action of the thrust. At the same time, it can increase the downward pressure between the cleaning module 3 and the surface to be cleaned, thereby increasing the contact area between the cleaning module 3 and the surface to be cleaned to improve the cleaning effect.
[0050] Please refer to Figure 3 The extension direction of link 21 (please refer to...) Figure 3 The intersection of the extension line L of the connecting rod 21 and the cleaning module 3 is located on the side of the cleaning module 3 whose center of gravity is away from the first direction X. It can be understood that the intersection of the extension direction of the connecting rod 21 and the cleaning module 3 refers to the point where the thrust acts on the cleaning module 3 in the extension direction of the connecting rod 21. Setting this intersection point on the side of the cleaning module 3 whose center of gravity is away from the first direction X allows the thrust to act more directly on the rear half of the cleaning module 3, thus reducing the problem of the cleaning module 3 lifting off the edge.
[0051] In some implementations, the connector 4 and the host 1 can be connected by bolts, snap-fit, plug-in or magnetic attraction, etc., which are not limited here.
[0052] In some embodiments, please refer to Figure 3 Multiple connecting rods 21 are provided, and the multiple connecting rods 21 are spaced apart in the second direction Y, which is perpendicular to the first direction X.
[0053] Therefore, by setting multiple connecting rods 21, the connection stability between the main unit 1 and the cleaning module 3 can be enhanced, and the thrust of the connecting rods 21 on the cleaning module 3 can be increased through multiple connecting rods 21, thereby reducing the problem of the cleaning module 3 lifting off the ground. It can also increase the downward pressure between the cleaning module 3 and the ground, and increase the contact area between the cleaning module 3 and the surface to be cleaned, thereby improving the cleaning effect.
[0054] In some embodiments, please refer to Figure 3 Any two links 21 are arranged parallel to each other in the second direction Y. This ensures that no two links 21 will interfere with each other, which helps to reduce the difficulty of arranging multiple links 21.
[0055] In some embodiments, multiple connection components 2 are provided, and the center of gravity of the cleaning module 3 is located between at least two connection components 2.
[0056] Therefore, by setting multiple connecting components 2, forces can be applied to the cleaning module 3 at multiple positions on the cleaning module 3 in a direction close to the surface to be cleaned, thereby increasing the downward pressure between the cleaning module 3 and the ground, reducing the problem of the cleaning module 3 lifting off the ground, and thus increasing the contact area between the cleaning module 3 and the surface to be cleaned, thereby improving the cleaning effect.
[0057] The center of gravity of the cleaning module 3 is located between at least two connecting components 2, so as to balance the forces on both sides of the center of gravity of the cleaning module 3, so as to keep the cleaning module 3 in balance.
[0058] In some embodiments, the cleaning device 10 further includes a lifting member (not shown in the figure), one end of which is connected to the main unit 1 and the other end of which is connected to the cleaning module 3. The lifting member is used to drive the cleaning module 3 to rise or fall along a second direction, Y, which is perpendicular to the first direction X. Thus, the lifting of the cleaning module 3 can be achieved by the lifting member.
[0059] For example, the second direction Y is Figure 2In the vertical direction, the lifting component can drive the cleaning module 3 to rise or fall along the second direction Y. When the cleaning module 3 rises, it can be stored in the main unit 1 to reduce the overall size of the cleaning device 10 and reduce storage difficulty. When the cleaning module 3 falls, it can extend out of the main unit 1 to clean the surface to be cleaned. Thus, the lifting component can be used to raise or lower the cleaning module 3, thereby switching the mode of the cleaning module 3.
[0060] In some implementations, the lifting component includes an electric telescopic rod, a pull rope, or other structures capable of lifting, which are not limited here.
[0061] In some embodiments, the connecting rod 21 and the connecting seat 4 are slidably engaged in a second direction, and the lifting member is connected to the connecting rod 21. The lifting member may be connected to the middle region of the connecting rod 21, and the connection method between the lifting member and the connecting rod 21 may be snap-fit, bolted, or welded, etc., which is not limited here.
[0062] This allows the connecting rod 21 and the connecting seat 4 to slide relative to each other in the second direction to achieve the raising or lowering of the cleaning module 3. For example, the connecting rod 21 and the connecting seat 4 can slide together in the second direction via a slide rail, so that the lifting and lowering movement of the cleaning module 3 can be achieved via the slide rail. The slide rail is relatively simple to set up, which helps to reduce the difficulty of setting up.
[0063] In some embodiments, one end of the connecting rod 21 is rotatably connected to the connecting seat 4, and the other end of the connecting rod 21 is rotatably connected to the cleaning module 3.
[0064] It is understandable that one end of the connecting rod 21 is hinged to the connecting seat 4, and the other end of the connecting rod 21 is hinged to the cleaning module 3. In this way, when the lifting component drives the cleaning module 3 to rise or fall in the second direction Y, the connecting rod 21 and the connecting seat 4 can rotate relative to each other, and the cleaning module 3 and the connecting rod 21 can rotate relative to each other. This allows the connecting rod 21 to rotate to match the rising or falling movement of the cleaning module 3, so as to better realize the rising or falling of the cleaning module 3.
[0065] It should be noted that the descriptions of each embodiment in the above embodiments have different focuses. For parts that are not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
