In all examples shown and discussed here, any specific values should be interpreted as being merely exemplary, not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0045] See also Figures 1 to 13 As shown, according to an embodiment of the present application, a cleaning device is provided. The cleaning device includes a main body 10 , a cleaning assembly 20 and a driving mechanism 30 .

[0046] The cleaning assembly 20 is arranged at the bottom of the main body 10, and the cleaning assembly 20 is arranged along the height direction of the main body 10 (such as the attached Figure 2 The cleaning assembly 20 is arranged to be raised and lowered in the middle Z direction, and has a first position protruding from the outer edge of the main body 10 and a second position retracted inside the main body 10. A driving mechanism 30 is provided between the main body 10 and the cleaning assembly 20 to drive the cleaning assembly 20 to rise and fall, and at the same time drive the cleaning assembly 20 to switch between the first position and the second position.

[0047] The cleaning device in this embodiment can be, for example, a sweeper, a scrubber, or a base station equipped with a sweeper or scrubber. The cleaning assembly 20 can be a mop 22 or a side-sweeping brush. Specifically, the drive mechanism 30 in this embodiment can drive the cleaning assembly 20 up and down in the height direction of the cleaning device, while also driving the cleaning assembly 20 to switch between a first position and a second position. This means that there are two possible positions: the cleaning assembly 20 is in the first position when descending and in the second position when ascending; and the cleaning assembly 20 is in the first position when ascending and in the second position when descending.

[0048] Compared with the prior art, the driving mechanism 30 in this embodiment is arranged between the main body 10 and the cleaning component 20 to drive the cleaning component 20 to rise and fall, and at the same time drive the cleaning component 20 to switch between the first position and the second position. The lifting of the cleaning component 20 can enable the cleaning device to cross obstacles when cleaning the floor, and the cleaning component 20 can switch between the first position and the second position so that the cleaning device has the ability to clean along the edge, thereby improving the cleaning effect of the cleaning device.

[0049] In a preferred embodiment, the cleaning assembly 20 is in a first position when it is lowered and in a second position when it is raised. When the cleaning assembly 20 is lowered and can protrude from the outer edge of the main body 10, there is a certain distance between the cleaning assembly 20 and the main body 10, and the cleaning assembly 20 is in contact with the ground at this time, thereby preventing the cleaning assembly 20 from interfering with the main body 10 during cleaning. In addition, when the cleaning assembly 20 protrudes from the main body 10, it can clean corners such as wall corners. When the cleaning assembly 20 is blocked by an obstacle, the driving mechanism 30 drives the cleaning assembly 20 to rise and then retracts it inside the main body 10. The cleaning assembly 20 is separated from the ground, and the obstacle cannot exert external force on the cleaning assembly 20, thereby allowing the cleaning device to cross the obstacle.

[0050] Of course, in some embodiments, the cleaning component 20 may also be in the second position when descending and in the first position when rising. For example, when the cleaning component 20 is a side sweeping brush, the side sweeping brush is in contact with the ground when descending to clean the ground, and when the side sweeping brush is raised, the side sweeping brush is separated from the ground and protrudes from the cleaning device, which is suitable for cleaning the side wall surfaces of corners.

[0051] Furthermore, the driving mechanism 30 includes a guide portion 32, a sliding portion 31, and a driving assembly 33. The guide portion 32 is fixedly mounted on the main body 10. The sliding portion 31 is slidably mounted on the guide portion 32, and the sliding portion 31 is fixedly connected to the cleaning assembly 20. The driving assembly 33 is mounted on the main body 10, and the driving assembly 33 is connected to the sliding portion 31 to drive the sliding portion 31 up and down, while driving the sliding portion 31 to reciprocate along the first direction. When the driving assembly 33 drives the sliding portion 31 to descend, it simultaneously drives the cleaning assembly 20 to switch from the second position to the first position; when the driving assembly 33 drives the sliding portion 31 to ascend, it simultaneously drives the cleaning assembly 20 to switch from the first position to the second position.

[0052] Specifically, as attached Figure 4 , Attachment Figure 5 and attached Figure 13 As shown, the cleaning assembly 20 includes a base plate 21 and a mop 22. The mop 22 is mounted on the base plate 21. One end of a sliding portion 31 is fixedly connected to the base plate 21. When the sliding portion 31 slides in a first direction, it drives the base plate 21 from the second position to the first position, thereby causing the mop 22 to protrude from the outer edge of the main body 10 to clean the floor. When the sliding portion 31 slides in a direction opposite to the first direction under the drive assembly 33, the sliding portion 31 drives the base plate 21 from the first position to the second position. At this time, the mop 22 and the base plate 21 are raised to a certain height and no longer in contact with the floor.

[0053] In addition, the guide portion 32 and the sliding portion 31 each include one or more. When the guide portion 32 and the sliding portion 31 each include multiple, the multiple guide portions 32 and the multiple sliding portions 31 correspond to each other one by one and are arranged along the first direction (such as the attached Figure 4 In a specific embodiment, the guide portions 32 and the sliding portions 31 each include two, and the two guide portions 32 and the two sliding portions 31 are spaced apart along the first direction in a one-to-one correspondence. Since the bottom plate 21 is relatively long, in this embodiment, the two sliding portions 31 are connected to the bottom plate 21, thereby improving the connection strength between the sliding portions 31 and the bottom plate 21.

[0054] At this time, an installation cavity 101 is provided in the main body 10, and the guide portion 32 includes a wedge block 321, which is fixedly provided in the installation cavity 101 and extends along the first direction. The surface of the wedge block 321 facing away from the cleaning component 20 is a slope 3211, and the slope 3211 is inclined along the height direction of the main body 10, and the sliding portion 31 is slidably provided on the slope 3211.

[0055] Specifically, the main body 10 includes a mounting plate 11 and an upper cover 12. The upper cover 12 is mounted on the mounting plate 11 and surrounds the mounting cavity 101. When the driving assembly 33 drives the sliding portion 31 to slide from the top of the wedge block 321 to the bottom of the wedge block 321, the cleaning assembly 20 is driven by the sliding portion 31 to descend in a direction opposite to the height direction, and the cleaning assembly 20 switches from the second position to the first position, at which point the cleaning assembly 20 can clean the floor. When the driving assembly 33 drives the sliding portion 31 to slide from the bottom of the wedge block 321 to the top of the wedge block 321, the cleaning assembly 20 is driven by the sliding portion 31 to ascend in the height direction, and the cleaning assembly 20 switches from the first position to the second position. At this time, there is a certain distance between the cleaning assembly 20 and the floor, allowing the cleaning assembly 20 to avoid obstacles. In this embodiment, the cross-sectional area of the wedge block 321 gradually decreases along the first direction. The cross-sectional area of the wedge block 321 refers to the surface obtained by intercepting the wedge block 321 by a plane perpendicular to the first direction, thereby ensuring that when the sliding part 31 slides along the first direction, the cleaning component 20 switches from the second position to the first position.

[0056] Furthermore, the main body 10 is located in the width direction of the wedge block 321 (as shown in the attached Figure 12 Avoidance gaps 111 are provided on both sides (in the middle X direction), and the avoidance gaps 111 are connected to the installation cavity 101; the sliding portion 31 includes a slider 311, the slider 311 is installed in the installation cavity 101, and a slide groove 3111 is provided on the slider 311, the wedge block 321 is located in the slide groove 3111, and the opposite sides of the slider 311 pass through the avoidance gaps 111 to connect with the cleaning component 20.

[0057] In this embodiment, the slider 311 is U-shaped, with the U-shaped opening of the slider 311 forming a slide groove 3111, which is buckled on the wedge block 321. The two ends of the U-shaped opening of the slider 311 pass through the avoidance notch 111 and connect to the cleaning assembly 20, so that the slider 311 can slide on the wedge block 321 without interfering with the main body 10. In this embodiment, the extension direction of the avoidance notch 111 is consistent with the first direction. In addition, the extension length of the avoidance notch 111 can also limit the sliding range of the slider 311.

[0058] Furthermore, a limiting portion 40 is provided on the wedge block 321 , and the limiting portion 40 is provided at both ends of the inclined surface 3211 along the first direction.

[0059] Specifically, the limiting portion 40 on the wedge block 321 is used to limit the sliding range of the slider 311. If the slider 311 slides too far from the bottom of the wedge block 321 to the top of the wedge block 321, the cleaning assembly 20 may rise too far, causing interference between the cleaning assembly 20 and the main body 10. If the limiting portion 40 is not provided when the slider 311 slides from the top of the wedge block 321 to the bottom of the wedge block 321, the cleaning assembly 20 may descend too far, causing excessive pressure on the ground by the cleaning assembly 20, thereby causing the cleaning assembly 20 to lock and malfunction. It may also cause the slider 311 to detach from the wedge block 321, ultimately preventing the cleaning assembly 20 from switching between the first position and the second position.

[0060] Furthermore, the limiting portion 40 includes a limiting protrusion 41 and / or a limiting baffle 42 , and the limiting protrusion 41 and / or the limiting baffle 42 protrude from the inclined surface 3211 .

[0061] It should be noted that "the limiting portion 40 includes the limiting protrusion 41 and / or the limiting baffle 42" refers to one of the following situations: the limiting portion 40 includes the limiting protrusion 41, the limiting baffle 42, or the limiting protrusion 41 and the limiting baffle 42. Similarly, "the limiting protrusion 41 and / or the limiting baffle 42 protrude from the inclined surface 3211" refers to one of the following situations: the limiting protrusion 41 protrudes from the inclined surface 3211, the limiting baffle 42 protrudes from the inclined surface 3211, or the limiting protrusion 41 and the limiting baffle 42 protrude from the inclined surface 3211. In this embodiment, the limiting portion 40 includes the limiting protrusion 41 and the limiting baffle 42, and both the limiting protrusion 41 and the limiting baffle 42 protrude from the inclined surface 3211.

[0062] Furthermore, the limiting portion 40 is provided on the top of the wedge block 321 , and the limiting portion 40 extends downwardly by a predetermined length along the inclined direction of the inclined surface 3211 .

[0063] As attached Figure 12As shown, in a specific embodiment, the limiting portion 40 provided on the top of the wedge block 321 is a limiting protrusion 41. The limiting protrusion 41 extends downwardly by a predetermined length along the inclination direction of the inclined surface 3211. That is, the limiting protrusion 41 extends a predetermined length from the top of the wedge block 321 along the inclination direction of the inclined surface 3211 to the bottom of the wedge block 321, thereby limiting the sliding movement of the slider 311. The limiting portion 40 provided on the bottom of the wedge block 321 is a limiting stopper 42. The limiting stopper 42 extends along the height direction of the main body 10, thereby preventing the slider 311 from separating from the wedge block 321.

[0064] Furthermore, the driving assembly 33 includes an elastic member 331, which is arranged between the sliding part 31 and the guide part 32 and / or the elastic member 331 is arranged between the sliding part 31 and the main body 10, and the extension and contraction direction of the elastic member 331 is consistent with the first direction or the inclination direction of the inclined surface 3211.

[0065] Specifically, "the elastic member 331 is arranged between the sliding portion 31 and the guide portion 32 and / or the elastic member 331 is arranged between the sliding portion 31 and the main body 10" refers to one of the three situations: the elastic member 331 is arranged between the sliding portion 31 and the guide portion 32, the elastic member 331 is arranged between the sliding portion 31 and the main body 10, and the elastic member 331 is arranged between the sliding portion 31 and the guide portion 32 and between the sliding portion 31 and the main body. When the elastic member 331 is arranged between the sliding portion 31 and the guide portion 32, after the driving mechanism 30 drives the cleaning component 20 to rise, the elastic member 331 is compressed. At this time, the elastic member 331 applies a certain elastic force to the sliding portion 31 to prevent the sliding portion 31 from colliding with the limiting protrusion 41; after the driving mechanism 30 removes the external force applied to the cleaning component 20, the elastic member 331 applies elastic force to the sliding portion 31, so that the sliding portion 31 descends along the inclined surface 3211, and finally causes the cleaning component 20 to descend. When the elastic member 331 is arranged between the main body 10 and the sliding part 31, the elastic member 331 is compressed after the cleaning component 20 descends. At this time, the elastic member 331 applies a certain elastic force to the sliding part 31, thereby preventing the sliding part 31 from continuing to descend along the inclined surface 3211, and eventually causing the sliding part 31 to collide with the limit baffle 42; on the other hand, after the driving mechanism 30 removes the external force applied to the cleaning component 20, the elastic member 331 gradually returns to its original state from the extended state. At this time, the elastic member 331 applies a certain pulling force to the sliding part 31, thereby driving the sliding part 31 to move downward along the inclined surface 3211.

[0066] In a specific embodiment, as shown in the attached Figure 7As shown, the elastic member 331 is a spring 3331, and the springs 3331 include multiple ones, at least one of which is disposed between the slider 311 and the wedge block 321, and at least one of which is disposed between the slider 311 and the main body 10. Specifically, when the cleaning assembly 20 is in the first position, the elastic force exerted on the sliding portion 31 by the spring 3331 disposed between the slider 311 and the wedge block 321 is greater than the elastic force exerted on the slider 311 by the spring 3331 disposed between the slider 311 and the main body 10, thereby causing the slider 311 to be pressed against a position close to the limiting baffle 42, thereby preventing the slider 311 from sliding on the wedge block 321 when the cleaning assembly 20 is subjected to an external force. Of course, when the cleaning component 20 is in the first position, the elastic force applied to the sliding portion 31 by the spring 3331 arranged between the slider 311 and the wedge block 321 can be the same as the elastic force applied to the slider 311 by the spring 3331 arranged between the slider 311 and the main body 10. At this time, if the cleaning component 20 is subjected to an external force opposite to the first direction or an external force opposite to the inclination direction of the inclined surface 3211, the cleaning component 20 can rise a certain distance, so that the cleaning component 20 can cross the obstacle.

[0067] Of course, the spring 3331 may be provided only between the sliding portion 31 and the guide portion 32, or only between the sliding portion 31 and the main body. Furthermore, the elastic member 331 in this embodiment may extend and retract in other directions, as long as the elastic force exerted by the spring 3331 on the slider 311 generates a force component in the direction of the inclined surface 3211.

[0068] In addition, as attached Figure 7 As shown, a guide channel 3212 is defined at the top of the wedge block 321. The extension direction of the guide channel 3212 is aligned with the inclination direction of the inclined surface 3211. The drive assembly 33 also includes a drive member 332 and a pull cord 333. The drive member 332 is disposed within the mounting cavity 101. The first end of the pull cord 333 is connected to the drive member 332. The second end of the pull cord 333 passes through the guide channel 3212 and is connected to the sliding portion 31. Driven by the drive member 332, the pull cord 333 pulls the sliding portion 31 along the inclination direction of the inclined surface 3211.

[0069] Specifically, as attached Figure 12As shown, the guide channel 3212 extends from the top of the wedge block 321 along the inclined direction of the inclined surface 3211 to the bottom of the wedge block 321. The pull rope 333 passes through the end of the guide channel 3212 near the top of the wedge block 321 and is connected to the slider 311. When the driving member 332 drives the pull rope 333, the pull rope 333 pulls the slider 311 upward along the inclined direction of the inclined surface 3211, thereby causing the cleaning assembly 20 to rise and switch from the second position to the first position. When the driving member 332 is not in operation, the pull rope 333 is relaxed. At this time, the spring 3331 disposed between the slider 311 and the wedge block 321 applies an elastic force downward along the inclined surface 3211 to the slider 311, or the spring 3331 disposed between the slider 311 and the main body applies a tensile force to the slider 311, thereby causing the slider 311 to move downward along the inclined direction of the inclined surface 3211. At this time, the cleaning assembly 20 descends and moves from the second position to the first position.

[0070] In this embodiment, the driving member 332 is a motor 3321. When the motor 3321 rotates, the pull rope 333 is retracted, so that the pull rope 333 can apply tension to the slider 311. In this embodiment, the pull rope 333 includes two pull ropes, and the two pull ropes 333 are respectively connected to the two sliders 311. When the motor 3321 rotates, the two pull ropes 333 are tightened at the same time, so that the two pull ropes 333 apply tension to the two sliders 311 at the same time, so that the overall rising height of the cleaning component 20 is consistent.

[0071] In other embodiments, for example, when the cleaning component 20 is a side-sweeping brush, the driving component 33 does not need to be provided with a motor 3321 and a pull rope 333. The side-sweeping brush can be switched between the first position and the second position only by setting the initial elastic force of the spring 3331. That is, when the external force exerted by the obstacle on the side-sweeping brush is greater than the external force exerted by the spring on the side-sweeping brush, the side-sweeping brush can slide on the wedge block 321 to avoid the obstacle.

[0072] Furthermore, along the height direction of the main body 10 , a protective gap 50 is defined between the cleaning assembly 20 and the main body 10 , and a width A of the protective gap 50 is not less than 1 mm.

[0073] Specifically, to prevent interference between the cleaning assembly 20 and the main body 10 after it rises, a protective gap 50 is provided between the cleaning assembly 20 and the main body 10. The width of the protective gap 50 cannot be too small, that is, A is greater than or equal to 1mm. A protective gap 50 that is too small can easily cause interference between the cleaning assembly 20 and the main body 10. In addition, when the cleaning assembly 20 moves from the second position to the first position, the maximum distance of the protective gap 50 does not exceed 11mm to prevent the cleaning assembly 20 from being stuck on the ground and thus malfunctioning. When the cleaning assembly 20 switches between the first and second positions, the width A of the protective gap 50 can be 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, and 11mm.

[0074] In addition, in this embodiment, motor 3321 is a lifting motor, and one end of a pull cord 333 is wrapped around the lifting motor. When the lifting motor rotates clockwise, the extended portion of the pull cord 333 is retracted by the lifting motor, causing the pull cord 333 to pull the slider 311 upward along the inclined surface 3211. When the lifting motor rotates counterclockwise, the pull cord 333 relaxes, eliminating the tension exerted by the pull cord 333 on the slider 311, thereby causing the slider 311 to move downward along the inclined surface 3211 under the elastic force of the spring 3331. Furthermore, when an obstacle exerts excessive external force on the outwardly extending portion of the cleaning assembly 20 in a direction opposite to the first direction, the external force overcomes the elastic force exerted by the spring 3331, causing the cleaning assembly 20 to be lifted to a certain height and thereby cross the obstacle. Furthermore, in this embodiment, the drive mechanism 30 has a simple structure and does not interfere with the other components of the cleaning device, thereby improving the service life of the cleaning device to a certain extent.

[0075] In summary, the present application has the following beneficial effects: the cleaning device can simultaneously realize the outward expansion and lifting of the cleaning component 20, so that when the cleaning device is mopping the floor normally, the cleaning component 20 expands outward and mops the floor along the edge to cover a wide range, and the cleaning effect of the cleaning device is better than that of the prior art. In addition, when the cleaning device encounters an obstacle, the outward expansion portion of the cleaning component 20 is squeezed and passively lifted, thereby preventing the obstacle from damaging the cleaning component 20. Secondly, the cleaning device can also actively lift the cleaning component 20. For example, after the cleaning device returns to a stop state, in order to avoid friction between the cleaning component 20 and the floor, the cleaning component 20 will be lifted off the floor under the action of the motor 3321.

[0076] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0077] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0078] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
