Description

Technical Field

[0001] This disclosure relates to the field of cleaning equipment technology, and specifically to a cleaning device, cleaning apparatus, and covering assembly. Background Technology

[0002] With economic development and improved living standards, people's demands for environmental hygiene are increasing. To save manpower, various cleaning equipment has emerged. Cleaning equipment is usually equipped with cleaning devices for cleaning work surfaces, such as rollers and brushes.

[0003] In existing technologies, some cleaning devices have an upward lifting function so that the cleaning device can be lifted in time when it travels over the carpet to avoid contaminating the carpet. However, in practical applications, there is still a risk of water dripping from the lifted cleaning device, which may cause the carpet to be contaminated with dirty water. In addition, for long-pile carpets, if the lifting height of the cleaning device is insufficient, the long pile can easily come into contact with the cleaning device, which can also cause carpet contamination.

[0004] To address the aforementioned technical issues, existing technologies CN222303849 and CN119453864 incorporate an additional baffle on the cleaning device. This baffle can move to a position that isolates the cleaning device from the carpet, thereby preventing the cleaning device from contaminating the carpet after being lifted. However, these existing technologies require an additional drive motor for the baffle, and the movement of the baffle and the lifting of the cleaning device are controlled independently by different drive motors. This increases the cost and weight of the cleaning device, and complicates the control logic. Utility Model Content

[0011] When the cleaning component is in a state of being close to or in contact with the working surface, the covering component is located in the second position relative to the cleaning component.

[0012] In one embodiment of this disclosure, when the cleaning component moves to a first preset position in a direction away from the work surface, the transmission component is configured to begin applying a force to the covering component, so that the covering component tends to move toward the first position.

[0013] In one embodiment of this disclosure, the transmission component is guided and fitted onto the cleaning component and is pulsatorically connected to the covering component; when the covering component is in a second position, the transmission component is configured to be carried on the cleaning component via the covering component.

[0014] As the cleaning component continues to move away from the working surface from the first preset position, the transmission component is configured to begin to be subjected to an external force relative to the cleaning component, so as to push the covering component to move towards the first position.

[0015] In one embodiment of this disclosure, the covering assembly is configured to be connected to the cleaning assembly via an elastic component; in the absence of external force, the covering assembly is held in the second position under the elastic force of the elastic component;

[0016] When the cleaning component moves toward the working surface to the second preset position, the external force on the transmission component is removed, and the covering component moves from the first position to the second position under the action of the elastic force; the second preset position is the same position or a different position from the first preset position.

[0017] In one embodiment of this disclosure, a blocking member is further provided on the body, the blocking member being located on the path of the transmission assembly moving away from the working surface; when the cleaning assembly moves away from the working surface to a first preset position, the transmission assembly abuts against the blocking member;

[0018] As the cleaning component continues to move away from the working surface from the first preset position, the transmission component is configured to move relative to the cleaning component under the action of the blocking member, so as to drive the covering component to move towards the first position.

[0019] In one embodiment of this disclosure, the two sides of the cleaning device in the lateral direction are referred to as the first side and the second side, respectively; the motion component includes a movable seat that guides the body; the cleaning component is configured to be supported on the movable seat via a connecting arm; an inclined guide surface is provided on the movable seat at a position in the direction of the second side of the connecting arm;

[0020] During the movement of the movable seat towards the first side, the connecting arm is pressed and drives the cleaning component to move away from the working surface along the guide surface. During the movement of the movable seat towards the second side, the connecting arm drives the cleaning component to move closer to the working surface under its own weight.

[0021] In one embodiment of this disclosure, the transmission assembly is located in the direction of the first side of the cleaning assembly, and the blocking member is disposed at the end of the first side of the movable seat; during the process of the cleaning assembly moving away from the working surface, the movable seat drives the blocking member to extend in the direction of the first side to the path of the transmission assembly moving away from the working surface.

[0022] In one embodiment of this disclosure, the covering assembly is hinged to the cleaning assembly and configured to rotate between a second position and a first position along its hinge axis; the connection position of the transmission assembly and the covering assembly is configured to deviate from the hinge axis, so that the transmission assembly can drive the covering assembly to rotate toward the first position during movement relative to the cleaning assembly.

[0023] In one embodiment of this disclosure, one of the transmission component and the covering component is provided with a sliding groove, and the other is provided with a first flange that cooperates with the sliding groove; during the movement of the transmission component relative to the cleaning component, the first flange abuts against the inner wall of the sliding groove, so that the transmission component drives the covering component to rotate in the direction of the first position.

[0024] In one embodiment of this disclosure, the first flange is configured to be located adjacent to the hinge point between the covering assembly and the cleaning assembly.

[0025] In one embodiment of this disclosure, the forward direction of the cleaning device is referred to as the front; when in the first position, the covering component is configured to extend at least 30° forward and backward along the circumferential direction of the cleaning component from a position directly below the cleaning component.

[0026] In one embodiment of this disclosure, the covering assembly includes a main body and a mounting portion disposed on at least one side of the main body, the mounting portion being movably connected to at least one sidewall of the cleaning assembly; the main body is configured to extend along the axial direction of the cleaning assembly, and when located in the first position, at least a portion of the main body is located between the cleaning assembly and the working surface.

[0027] In one embodiment of this disclosure, the body includes a top cover assembly, and the cleaning assembly is movably mounted below the top cover assembly; a portion of the top cover assembly is configured to extend to the rear side of the cleaning assembly and enclose the cleaning assembly to form a receiving space; when in a second position, at least a portion of the covering assembly is housed in the receiving space.

[0028] In one embodiment of this disclosure, the cover assembly includes a first cover movably connected to the cleaning assembly, and a second cover disposed on the upper cover assembly and located behind the cleaning assembly; the first cover and the second cover cooperate via a guide mechanism; the first cover is configured to move to a second position retracted in the gap between the second cover and the cleaning assembly, and to move relative to the second cover to a first position disengaged from the gap.

[0029] In one embodiment of this disclosure, the second cover is configured to be connected to the upper cover assembly via a flexible connector, and the first cover is configured to move the second cover by a predetermined displacement against the elastic force of the flexible connector during movement toward the first position.

[0030] In one embodiment of this disclosure, one of the first cover and the second cover is provided with a second flange, and the other is provided with a guide groove that mates with the second flange.

[0031] According to a second aspect of this disclosure, a cleaning apparatus is also provided, comprising:

[0032] A cleaning component for cleaning a work surface; the cleaning component is configured to move in a direction away from or towards the work surface;

[0033] A covering assembly is movably connected to the cleaning assembly and configured to follow the cleaning assembly in a direction away from or towards the work surface; the covering assembly is movable relative to the cleaning assembly between a first position and a second position.

[0034] A transmission component is used to drive the covering component to move relative to the cleaning component;

[0035] When the cleaning component is in a state away from the working surface, the covering component is located in the first position, and at least part of the covering component is located between the cleaning component and the working surface;

[0036] When the cleaning component is in a state close to or in contact with the working surface, the covering component is located in the second position.

[0037] According to a third aspect of this disclosure, a covering assembly is also provided, the covering assembly being movably connected to the cleaning assembly, the covering assembly comprising:

[0038] A first cover, the first cover being configured to move relative to the cleaning component between a first position and a second position;

[0039] The second cover is configured to engage with the first cover via a guide mechanism and is configured to move relative to the cleaning assembly under the actuation of the first cover;

[0040] When in the first position, at least a portion of the first cover is located between the cleaning component and the work surface;

[0041] When in the second position, at least a portion of the first cover is configured to be accommodated in the gap between the second cover and the cleaning component.

[0042] In one embodiment of this disclosure, the first cover is movably connected to the cleaning component, the cover component is movably connected to the cleaning component, the cleaning component is mounted below the upper cover component, and the second cover is disposed on the upper cover component;

[0043] Part of the top cover assembly is configured to extend to the rear side of the cleaning assembly and enclose the cleaning assembly to form a receiving space; when in the second position, at least part of the first cover is housed in the receiving space.

[0044] In one embodiment of this disclosure, the second cover is configured to be connected to the upper cover assembly via a flexible connector, and the first cover is configured to move the second cover by a predetermined displacement against the elastic force of the flexible connector during movement toward the first position.

[0045] In one embodiment of this disclosure, one of the first cover and the second cover is provided with a second flange, and the other is provided with a guide groove that mates with the second flange.

[0046] One beneficial effect of this disclosure is that, when the cleaning equipment travels to the carpet and lifts the cleaning component, at least part of the covering component is located between the cleaning component and the working surface, thus physically isolating the cleaning component from the working surface and preventing the cleaning component from contaminating the carpet. Specifically, when the cleaning component is lifted and dripping water, the wastewater can be caught by the covering component; for long-pile carpets, even if the cleaning component is not lifted high enough, the long pile will only come into contact with the clean bottom surface of the covering component and will not come into contact with the cleaning component.

[0047] Furthermore, this disclosure achieves linkage between the cleaning component and the covering component by incorporating a transmission assembly: when the cleaning component is raised, the covering component moves to a first position, thereby blocking the cleaning component from the working surface; when the cleaning component is lowered, the covering component can return to a second position, allowing the cleaning component to make normal contact with the working surface and continue subsequent cleaning work. This linkage design eliminates the need for an additional drive source for the movement of the covering component, simplifying the cleaning equipment structure and reducing costs.

[0048] Furthermore, existing technologies require an additional drive source to control the movement of the covering component. To accurately determine when to start driving the covering component's movement, an additional sensor is typically needed to detect the lifting and lowering position of the cleaning component, and the position signal is used to control the forward and reverse rotation of the motor, resulting in highly complex control logic. In contrast, the covering component of this application is linked to the cleaning component. It automatically blocks the view whenever the cleaning component is raised and automatically avoids it whenever the cleaning component is lowered. Therefore, only the lifting and lowering of the cleaning component needs to be controlled, eliminating the need for independent control of the covering component, thus significantly simplifying the control logic.

[0049] Other features and advantages of this disclosure will become clear from the following detailed description of exemplary embodiments with reference to the accompanying drawings. Attached Figure Description

[0065] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0066] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0067] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0068] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0069] In this article, terms such as "up," "down," "front," "back," "left," and "right" are used only to indicate the relative positional relationship between related parts, rather than to define the absolute position of these related parts.

[0070] In this article, "first," "second," etc., are used only to distinguish one another, and not to indicate degree of importance, order, or prerequisite for each other.

[0071] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0072] This embodiment provides a cleaning device, which can be a handheld cleaning device, such as a handheld washer, handheld vacuum cleaner, handheld floor scrubber, handheld fabric cleaner, or other handheld cleaning devices well known to those skilled in the art. It can also be a sweeping robot, mopping robot, or a sweeping-mopping robot, used to clean work surfaces (such as floors) that require cleaning. This embodiment will use a sweeping-mopping robot as an example for explanation.

[0073] For ease of description later, such as Figure 1 As shown, a spatial rectangular coordinate system is established: the forward direction of the cleaning equipment is denoted as the front, and the front-back direction extends along the X-axis, denoted as X1 and X2 respectively; the lateral direction of the cleaning equipment extends along the Y-axis, specifically, the two sides of the cleaning equipment in the lateral direction are denoted as the first side and the second side respectively, the direction of the first side is denoted as Y1 and the direction of the second side is denoted as Y2; the height direction of the cleaning equipment extends along the Z-axis, denoted as Z1 above and Z2 below.

[0074] refer to Figure 1 The cleaning equipment includes a body 1 and a cleaning device, wherein the body 1 serves as the basic structure for installing the cleaning equipment. Figure 1 Only the portion of the structure on body 1 used for mounting the cleaning device is shown. In the case of a sweeping and mopping robot, wheels can be installed on the bottom surface of body 1, allowing the robot to move independently on the work surface.

[0075] refer to Figures 1 to 3 The cleaning device disclosed herein includes a cleaning component 2 and a motion component 3. The cleaning component 2 is used to clean the work surface. Specifically, the cleaning component 2 may include components such as a roller 22, a roller brush, a mop disc, and a floor brush. Taking the cleaning component 2 including the roller 22 as an example, the roller 22 extends along the Y-axis and its two ends are rotatably connected to the machine body 1. By applying water to the roller 22, wet mopping and cleaning of the work surface can be achieved, thereby achieving a good cleaning effect.

[0076] The cleaning component 2 is configured to move relative to the body 1 in a direction away from or towards the working surface under the action of the motion component 3. Specifically, the direction away from the working surface is the Z1 direction, and the cleaning component 2 can be raised to detach from the working surface under the action of the motion component 3; the direction towards the working surface is the Z2 direction, and the cleaning component 2 can be lowered to re-engage with the working surface under the action of the motion component 3, thereby continuing to clean the working surface.

[0077] In one embodiment of this disclosure, reference is made to Figure 3 , Figure 7 , Figure 10 and Figure 11 The motion component 3 includes a drive member 31 and a movable seat 32 that guides and engages with the body 1. The movable seat 32 extends along the Y-axis and can move along the Y-axis under the drive of the drive member 31. Specifically, the drive member 31 can be a motor fixed relative to the body 1, and a drive gear 311 can be provided on its output shaft. A rack 321 that meshes with the drive gear 311 can be provided on the movable seat 32. The operation of the drive member 31 causes the drive gear 311 to rotate, thereby driving the movable seat 32 to move relative to the body 1 through the rack 321. When the movable seat 32 moves toward the first side direction (i.e., the Y1 direction), the cleaning component 2 can be raised to detach from the working surface under the action of the movable seat 32. When the movable seat 32 moves toward the second side direction (i.e., the Y2 direction), the cleaning component 2 can be lowered to re-engage with the working surface under the action of the movable seat 32.

[0078] Specifically, refer to Figure 7The cleaning component 2 is configured to be supported on the movable seat 32 via a connecting arm 23. The connecting arm 23 can be fixedly installed on the top cover 21 of the cleaning component 2. The connecting arm 23 includes a lifting rod 231 extending upward along the Z1 direction and a roller 232 rotatably connected to the top end of the lifting rod 231. The lifting rod 231 can be a pin structure, and the roller 232 is rotatably connected to the head position of the lifting rod 231. The cleaning component 2 can be supported on the movable seat 32 via the roller 232. The tail of the lifting rod 231 extends downward and is fixed or integrally formed to the upper end surface of the top cover 21.

[0079] refer to Figure 8 The machine body 1 is provided with a mounting base 10, which can serve as a support component for the machine body 1. The cleaning component 2 is located below the mounting base 10, thereby exposing the bottom of the roller 22 outside the machine body 1 to achieve cleaning of the working surface. The motion component 3 is installed above the mounting base 10, thereby being hidden inside the machine body 1. The mounting base 10 is provided with a through groove 101 extending along the Y-axis, and the movable seat 32 is provided with a floating groove 325 extending along the Y-axis. The lifting rod 231 of the connecting arm 23 passes through the through groove 101 of the mounting base 10 and the floating groove 325 of the movable seat 32 sequentially from the top cover 21 of the cleaning component 2, thereby allowing the top roller 232 to be supported on the movable seat 32.

[0080] refer to Figure 7 , Figure 10 and Figure 11 An inclined guide surface 322 is provided on the movable seat 32 at a position in the direction (Y2 direction) where the connecting arm 23 is located on the second side. During the movement of the movable seat 32 in the direction (Y1 direction) where the first side is located, the connecting arm 23 is pressed and moves along the guide surface 322 to move the cleaning component 2 away from the working surface (Z1 direction). During the movement of the movable seat 32 in the direction (Y2 direction) where the second side is located, the connecting arm 23 moves the cleaning component 2 towards the working surface (Z2 direction) under its own weight. Specifically, the roller 232 of the connecting arm 23 is used to cooperate with the guide surface 322. The roller 232 can climb the slope on the guide surface to lift the cleaning component 2 relative to the machine body 1; and the roller 232 can roll down the guide surface 322 under the weight of the cleaning component 2 to lower the cleaning component 2 relative to the machine body 1.

[0081] The process of the cleaning component 2 moving away from the working surface (Z1 direction) relative to the machine body 1 under the action of the motion component 3 is as follows: the drive component 31 works to make the drive gear 311 rotate, thereby driving the movable seat 32 to move in the direction of the first side (Y1 direction) through the rack 321; when the driving force provided by the drive component 31 reaches the lifting force required for the connecting arm 23 to climb the slope on the guide surface 322 (that is, at least the weight of the cleaning component 2 itself needs to be overcome), the guide surface 322 on the movable seat 32 can scoop up the roller 232, so that the roller 232 rolls up the slope along the guide surface 322, and drives the cleaning component 2 to be lifted through the lifting rod 231.

[0082] The process of the cleaning component 2 moving relative to the machine body 1 in the direction closer to the working surface (Z2 direction) under the action of the motion component 3 is as follows: the drive component 31 can provide the movable seat 32 with a force to reset in the direction of the second side (Y2 direction). During the process of the movable seat 32 moving relative to the cleaning component 2 in the Y2 direction, the roller 232 can roll downhill along the guide surface 322 under the gravity of the cleaning component 2 and the connecting arm 23, and drive the cleaning component 2 to descend through the lifting rod 231.

[0083] In one specific embodiment of this disclosure, reference is made to Figure 7 , Figure 8 and Figure 10 A limiting part 323 is provided on the movable seat 32. The limiting part 323 can be located at the end of the floating groove 325 in the Y1 direction, thereby restricting the degree of freedom of the connecting arm 23 to move relative to the movable seat 32 in the Y1 direction. When the roller 232 rolls downhill along the guide surface 322, the roller 232 can only roll up to abut against the limiting part 323, thereby preventing the roller 232 from detaching from the movable seat 32 due to inertia.

[0084] In one specific embodiment of this disclosure, two connecting arms 23 may be provided separately. Correspondingly, two floating grooves 325, two guide surfaces 322, and two limiting parts 323 are provided on the movable seat 32, and two through grooves 101 are provided on the mounting seat 10. The roller 22 of the cleaning component 2 is relatively heavy when wet. If only a single connecting arm 23 is provided, the connection may be unstable, easily damaged, unable to smoothly drive the cleaning component 2, and there may be a shift in the center of gravity. This disclosure enhances the lifting stability of the cleaning component 2 by providing two separate connecting arms 23.

[0085] It should be noted that cleaning equipment may pass over surfaces that do not require cleaning during operation. For example, for a robot vacuum and mop used for floor cleaning, when it passes over a carpet, the motion component 3 needs to be controlled to lift the cleaning component 2 upwards to prevent it from contacting the carpet and causing contamination. However, in practical applications, there is a risk of water dripping from the lifted cleaning component 2, which could still contaminate the carpet. Furthermore, for long-pile carpets, if the cleaning component 2 is not lifted high enough, the long fibers can easily come into contact with it, also causing carpet contamination.

[0086] To address the aforementioned problems, the cleaning apparatus of this disclosure further includes a covering assembly 4 and a transmission assembly 5. The covering assembly 4 is movably connected to the cleaning assembly 2 and is configured to follow the cleaning assembly 2 in a direction away from or towards the working surface. The covering assembly 4 is movable relative to the cleaning assembly 2 between a first position and a second position, and the transmission assembly 5 is used to drive the covering assembly 4 to move relative to the cleaning assembly 2. When the cleaning assembly 2 is in a state away from the working surface, the covering assembly 4 is located in the first position, at least partially positioned between the cleaning assembly 2 and the working surface; when the cleaning assembly 2 is in a state close to or in contact with the working surface, the covering assembly 4 is located relative to the cleaning assembly 2 in the second position.

[0087] It should be noted that the concepts of cleaning component 2 being far from and close to the working surface are relative. When the covering component 4 is in the first position, there is a large distance between the cleaning component 2 and the working surface; when the covering component 4 is in the second position, the cleaning component 2 can be close to the working surface or in contact with it. Specifically, in the following text, the cleaning component 2 is defined as having a first preset position and a second preset position relative to the working surface. At this point, the cleaning component 2 is at the critical position where the covering component 4 is about to move, and the height below the first preset position and the second preset position can be considered as being close to the working surface.

[0088] Specifically, the transmission assembly 5 is configured to drive the covering assembly 4 to a first position relative to the cleaning assembly 2 as the cleaning assembly 2 moves away from the working surface (Z1 direction). As the cleaning assembly 2 moves towards the working surface (Z2 direction), the covering assembly 4 moves to a second position relative to the cleaning assembly 2. During normal cleaning operation, the cleaning assembly 2 contacts the working surface for cleaning, while the covering assembly 4 remains in the second position. The covering assembly 4 in the second position does not affect the normal cleaning operation of the cleaning assembly 2; at least the bottom of the roller 22 is exposed and in contact with the working surface, allowing it to rotate relative to the working surface for cleaning.

[0089] In one embodiment of this disclosure, reference is made to Figure 1 and Figure 2 The main body 1 includes a top cover assembly 12, and a cleaning assembly 2 is movably mounted below the top cover assembly 12. It should be noted that "below" here refers to the top cover assembly 12 and the cleaning assembly 2 having a positional relationship of one being higher than the other, and does not exclude the possibility that the two may partially overlap in height; both the top cover assembly 12 and the cleaning assembly 2 have a certain height dimension, and there is a part of their height that overlaps, and this positional relationship also falls within the scope of protection of "below" in this article.

[0090] Part of the top cover assembly 12 is configured to extend to the rear side of the cleaning assembly 2 and enclose the cleaning assembly 2 to form a receiving space 13. In the second position, at least part of the covering assembly 4 is housed in the receiving space 13. Specifically, the receiving space 13 can be formed by the rear inner wall of the roller 22 and the top cover assembly 12, and the covering assembly 4 in the second position is housed in the receiving space 13 so as not to interfere with the normal cleaning operation of the roller 22.

[0091] Furthermore, such as Figure 3 As shown, the top cover 21 of the cleaning assembly 2 can extend to the front side of the roller 22, as... Figure 1 As shown, in this embodiment, the cover assembly 4 is housed at the rear side of the roller 22, so that the cover assembly 4 in the second position can together with the top cover 21 to form a semi-enclosed chamber for accommodating the roller 22. During the cleaning process of the roller 22 rotating, dirt on the roller 22 may be thrown outward under the action of centrifugal force. The cover assembly 4 in the second position can be used to block the dirt thrown backward by the roller 22, thereby preventing contamination from extending to the top cover assembly 12 at the rear of the cleaning assembly 2, and preventing contamination of the clean working surface behind the cleaning equipment that has already been cleaned.

[0092] During the movement of the cleaning component 2 away from the work surface (Z1 direction), that is, during the upward lifting process under the action of the motion component 3, the transmission component 5 can drive the covering component 4 from the second position to the first position. As mentioned earlier, the cleaning component 2 is usually only lifted when the cleaning equipment travels to a work surface that does not need to be cleaned (such as a carpet). At this time, at least part of the covering component 4 is located between the cleaning component 2 and the work surface, thus physically isolating the cleaning component 2 from the work surface and preventing the cleaning component 2 from contaminating the carpet. Specifically, when the cleaning component 2 is lifted and dripping water, the wastewater can be caught by the covering component 4; for long-pile carpets, even if the lifting height of the cleaning component 2 is insufficient, the long pile will only contact the clean bottom surface of the covering component 4 and will not contact the cleaning component 2.

[0093] Furthermore, this disclosure achieves linkage between the cleaning component 2 and the covering component 4 by setting up a transmission component 5: when the cleaning component 2 is raised, the covering component 4 moves to a first position, thereby blocking the cleaning component 2 from the working surface; when the cleaning component 2 is lowered, the covering component 4 can return to a second position, allowing the cleaning component 2 to make normal contact with the working surface, thus continuing subsequent cleaning work. Through this linkage design, there is no need to set up an additional drive source for the movement of the covering component 4, which helps to simplify the structure of the cleaning equipment and reduce costs.

[0094] Furthermore, existing technologies require an additional drive source to control the movement of the covering component 4. To accurately determine when to start driving the covering component 4, an additional sensor is typically needed to detect the lifting and lowering position of the cleaning component 2, and the forward and reverse rotation of the motor is controlled by the position signal, resulting in very complex control logic. In contrast, the covering component 4 of this application is linked to the cleaning component 2. It automatically blocks the view whenever the cleaning component 2 is raised, and automatically avoids the view whenever the cleaning component 2 is lowered. Therefore, only the lifting and lowering of the cleaning component 2 needs to be controlled, without the need for independent control of the covering component 4, thus greatly simplifying the control logic.

[0095] In one embodiment of this disclosure, reference is made to Figure 3 and Figure 4 The covering assembly 4 includes a main body 401 and a mounting portion 402 disposed on at least one side of the main body 401, the mounting portion 402 being movably connected to at least one side wall of the cleaning assembly 2. The main body 401 is configured to extend along the axial direction (Y-axis direction) of the cleaning assembly 2, and when in the first position, at least a portion of the main body 401 is located between the cleaning assembly 2 and the working surface. Specifically, the main body 401 is a structure on the covering assembly 4 for physically isolating the roller 22 from the working surface, while the mounting portion 402 is a structure for movably connecting with the cleaning assembly 2. The main body 401 may have an arc adapted to the roller 22, and its extension length is at least the same as the length of the roller 22, thereby achieving complete isolation between the roller 22 and the working surface when in the first position.

[0096] In one specific embodiment of this disclosure, a single mounting portion 402 is provided, which can be located on the Y1 direction side of the main body 401. The mounting portion 402 and the main body 401 can be fixedly connected, or they can be integrally formed. Since the cover assembly 4 is a lightweight shell structure, the mounting portion 402 provided on one side is sufficient to stably and movably connect the entire cover assembly 4 to the cleaning assembly 2.

[0097] As previously described, this disclosure achieves linkage between the cleaning component 2 and the covering component 4 by setting a transmission component 5. Specifically, in this embodiment, the structure for transmission cooperation with the transmission component 5 is set on the mounting part 402, thereby ensuring the structural integrity of the main body 401 and ensuring its physical isolation effect. Based on this, if mounting parts 402 on both sides are set, corresponding transmission components 5 on both sides are required, which would result in very high requirements for assembly accuracy. Once there is a large assembly error, it may cause uneven force on both sides of the covering component 4, which may lead to the covering component 4 tilting or jamming during movement. This disclosure sets a single-sided mounting part 402, thereby driving the covering component 4 to rotate on one side, thereby reducing the assembly accuracy requirements and avoiding tilting and jamming of the covering component 4 during movement.

[0098] In one embodiment of this disclosure, reference is made to Figure 3 , Figure 4 and Figure 12 The cover assembly 4 can be hinged to the cleaning assembly 2 and is configured to rotate between a second position and a first position along its hinge axis. A hinge hole 25 is provided on the side wall of the cleaning assembly 2, and a through hole 43 can be provided on the cover assembly 4. Specifically, the through hole 43 can be provided on the mounting portion 402. The hinge member 431 is configured to pass through the through hole 43 and extend into the hinge hole 25, thereby hinged the cover assembly 4 to the cleaning assembly 2. Figure 12 As shown, Figure ① on the left shows the state of the covering assembly 4 in the second position, and Figure ② on the right shows the state of the covering assembly 4 in the first position. The covering assembly 4 is capable of rotating along the hinge axis (i.e., the axis of the hinge 431), thereby switching between the second position and the first position.

[0099] In one specific embodiment of this disclosure, reference is made to Figure 12 In Figure ② on the right, when in the first position, the covering component 4 is configured to extend at least 30° forward and backward along the circumferential direction of the cleaning component 2 from a position directly below the cleaning component 2. Specifically, after the roller 22 is lifted, wastewater easily flows under gravity and drips from a position directly below the roller 22. Therefore, the main body 401 of the covering component 4 in the first position is at least partially located directly below the cleaning component 2, thereby accurately catching the dripping wastewater and preventing the cleaning component 2 from contaminating the carpet.

[0100] Furthermore, the covering component 4 located in the first position should have a certain covering area below the cleaning component 2, such as... Figure 12As shown in Figure ②, the angle α of the covering component 4 extending forward (X1 direction) from the position directly below the cleaning component 2 along the circumferential direction of the cleaning component 2 is denoted as the covering component 4, and the angle β of the covering component 4 extending backward (X2 direction) is denoted as the covering component 4. Here, α ≥ 30°, β ≥ 30°, and α and β may be equal or unequal. The central angle of the covering component 4 is at least 60°. When in the first position, the covering component 4 has sufficient covering area directly below the cleaning component 2, so that even if the roller 22 is tilted and drips wastewater, the wastewater can be caught by the covering component 4, preventing the cleaning component 2 from contaminating the carpet.

[0101] In one embodiment of this disclosure, reference is made to Figure 1 , Figure 3 and Figure 6 The covering component 4 is configured to be connected to the cleaning component 2 via the elastic component 6. When no external force is applied, the covering component 4 is held in a second position by the elastic force of the elastic component 6. Specifically, the elastic component 6 can be a tension spring. A first mounting hook 24 can be provided on the side wall of the cleaning component 2, and a second mounting hook 44 can be provided on the side wall of the covering component 4. The two ends of the tension spring are connected to the cleaning component 2 and the covering component 4 respectively via the first mounting hook 24 and the second mounting hook 44.

[0102] In this embodiment, the covering component 4, located in the second position, is positioned at the rear side of the roller 22. The first mounting hook 24 can be located at the front side of the roller 22, and the second mounting hook 44 can be located at the end of the mounting portion 402 away from the main body portion 401. Under the pulling force of the elastic component 6, the second mounting hook 44 can be held as close as possible to the first mounting hook 24. This ensures that the end of the mounting portion 402 away from the main body portion 401 is held at the front side of the roller 22, and the main body portion 401 is correspondingly held at the rear side of the roller 22. That is, the covering component 4 can be held in the second position under the action of the elastic component 6.

[0103] In one embodiment of this disclosure, when the cleaning component 2 moves to a first preset position in a direction away from the working surface (Z1 direction), the transmission component 5 is configured to begin applying a force to the covering component 4, causing the covering component 4 to tend to move towards the first position. The cleaning component 2 can lift or lower the covering component 4 together. Before it is lifted to the first preset position, the covering component 4 is not subjected to a force from the transmission component 5 and can remain in the second position during the lifting process. When it is lifted to the first preset position, the transmission component 5 begins to apply a force to the covering component 4. During the process of continuing to lift upward from the first preset position, the transmission component 5 can overcome the elastic force of the elastic component 6 and push the covering component 4 to the first position.

[0104] In one embodiment of this disclosure, the cleaning component 2 is capable of floating up and down during the cleaning process. During this floating process, the covering component 4 remains in the second position and does not rotate towards the first position. It is understood that the amplitude of the vertical floating of the cleaning component 2 is very small, and the lifting height during the floating process is much less than the height of the first preset position. Therefore, the transmission component 5 does not exert any force on the covering component 4, and the covering component 4 can remain in the second position.

[0105] In one embodiment of this disclosure, the transmission assembly 5 is guided and fitted onto the cleaning assembly 2, with reference to... Figure 2 and Figure 3 The transmission component 5 is guided and installed on the side wall of the cleaning component 2 by the bracket 52. The bracket 52 forms a vertical groove 521 extending along the Z-axis. The transmission component 5 can move relative to the cleaning component 2 along the Z-axis under the limiting action of the vertical groove 521.

[0106] The transmission assembly 5 is drively connected to the cover assembly 4. When the cover assembly 4 is in the second position, the transmission assembly 5 is configured to be supported on the cleaning assembly 2 via the cover assembly 4. The connection position between the transmission assembly 5 and the cover assembly 4 is configured to offset from the hinge axis of the cover assembly 4, so that the transmission assembly 5 can drive the cover assembly 4 to rotate towards the first position during movement relative to the cleaning assembly 2. The force applied by the transmission assembly 5 to the cover assembly 4 is non-radial and does not pass through the rotation center of the cover assembly 4 (the hinge point between the cover assembly 4 and the cleaning assembly 2). The eccentric connection between the transmission assembly 5 and the cover assembly 4 enables the transmission assembly 5 to drive the cover assembly 4 to rotate.

[0107] In one specific embodiment of this disclosure, reference is made to Figure 6 One of the transmission component 5 and the covering component 4 has a sliding groove 51, and the other has a first flange 45 that mates with the sliding groove 51. In this embodiment, the first flange 45 is disposed on the covering component 4, the sliding groove 51 is disposed on the transmission component 5, and the first flange 45 extends into the sliding groove 51. When the covering component 4 moves away from the working surface (Z1 direction) along with the cleaning component 2, the first flange 45 applies a force to the upper inner wall of the sliding groove 51, thereby driving the transmission component 5 to move upward together.

[0108] As the cleaning component 2 continues to move away from the working surface (Z1 direction) from the first preset position, the transmission component 5 is configured to begin to move relative to the cleaning component 2 under external force, in order to push the covering component 4 to move towards the first position. In the initial lifting stage, the cleaning component 2, the covering component 4, and the transmission component 5 rise synchronously, and there is no relative movement between the three; until the movement reaches the first preset position, the transmission component 5 begins to be acted upon by external force, thus causing the transmission component 5 to be unable to continue rising; during the continued upward lifting process from the first preset position, the cleaning component 2 drives the covering component 4 to continue to rise, and the transmission component 5 remains stationary under the action of external force, that is: the transmission component 5 moves relative to the cleaning component 2 and the covering component 4, and the covering component 4 is subjected to the force from the transmission component 5, thereby overcoming the elastic force of the elastic component 6 and beginning to move towards the first position.

[0109] During the movement of the transmission assembly 5 relative to the cleaning assembly 2, the first flange 45 abuts against the inner wall of the sliding groove 51, causing the transmission assembly 5 to drive the covering assembly 4 to rotate towards the first position. Specifically, when the covering assembly 4 rises and the transmission assembly 5 remains stationary, the upper inner wall of the sliding groove 51 applies a downward force to the first flange 45. The sliding groove 51 has a certain dimension at least in the X-axis direction and can restrict the degree of freedom of the first flange 45 in the Z-axis direction; for example, the sliding groove 51 can be a transverse groove extending along the X-axis direction. When subjected to a downward force, the covering assembly 4 will rotate towards the first position along the hinge axis, at which time the first flange 45 moves along the X-axis direction within the sliding groove 51. This achieves the goal of the transmission assembly 5 driving the covering assembly 4 to move towards the first position during its movement relative to the cleaning assembly 2.

[0110] In one specific embodiment of this disclosure, reference is made to Figure 4 The first flange 45 is configured to be located near the hinge point between the cover assembly 4 and the cleaning assembly 2. This results in a shorter lever arm when the upper inner wall of the sliding groove 51 applies force to the first flange 45, thereby reducing force loss during transmission and allowing the applied force to be more efficiently converted into power to rotate the cover assembly 4. Furthermore, the proximity to the hinge point means that even a small displacement of the first flange 45 can cause the cover assembly 4 to rotate significantly around the hinge axis, allowing the cover assembly 4 to move quickly from the second position to the first position. In addition, because the first flange 45 is located near the hinge point, the travel distance of the first flange 45 within the sliding groove 51 can be correspondingly shortened, allowing the sliding groove 51 to be shorter. The shortened length of the sliding groove 51 allows for a smaller overall size of the transmission assembly 5, which helps to avoid interference between the transmission assembly 5 and other structures on the cleaning equipment, improving the overall compactness of the cleaning equipment.

[0111] During the rotation of the covering assembly 4, the transmission assembly 5 may structurally interfere with the second mounting hook 44 because the second mounting hook 44 on the covering assembly 4 protrudes outward. To solve this problem, in one embodiment of this disclosure, reference is made to... Figure 5 The transmission component 5 can be constructed in a crank shape, and the side wall of the transmission component 5 near the second mounting hook 44 can be constructed in a curved shape, thereby forming a clearance area 53. The shape of the clearance area 53 is adapted to the rotation path of the second mounting hook 44, thereby allowing the cover component 4 to rotate smoothly without structural interference with the transmission component 5.

[0112] In one embodiment of this disclosure, the cleaning device further includes a blocking member 324 disposed on the body 1, located on the path of the transmission assembly 5 moving away from the working surface (Z1 direction). When the cleaning assembly 2 moves away from the working surface (Z1 direction) to a first preset position, the transmission assembly 5 abuts against the blocking member 324, thereby causing the transmission assembly 5 to be subjected to external force, preventing the transmission assembly 5 from continuing to rise. During the process of the cleaning assembly 2 continuing to move away from the working surface (Z1 direction) from the first preset position, the cleaning assembly 2 drives the covering assembly 4 to continue to rise, while the transmission assembly 5 remains stationary under the action of external force. That is, the transmission assembly 5 is configured to move relative to the cleaning assembly 2 under the action of the blocking member 324, so as to drive the covering assembly 4 to move in the direction of the first position.

[0113] This disclosure achieves linkage between the lifting and lowering of the cleaning component 2 and the movement of the covering component 4 by setting a blocking member 324. The blocking member 324 is located on the rising path of the transmission component 5, so that when the transmission component 5 rises to the first preset position, it abuts against the blocking member 324, and the transmission component 5 can convert this resistance into the power for the covering component 4 to move to the first position. Through the above linkage design, there is no need to set a drive source for the movement of the covering component 4, which helps to simplify the structure of the cleaning equipment and reduce costs.

[0114] In one specific embodiment of this disclosure, the blocking member 324 may be a blocking rod, blocking block, or other structure fixed to the body 1, and the blocking member 324 is at least partially located directly above the transmission assembly 5. When the transmission assembly 5 moves upward together with the cleaning assembly 2 and the covering assembly 4 to the first preset position, the transmission assembly 5 comes into contact with the blocking member 324, and the blocking member 324 can prevent the transmission assembly 5 from continuing to rise.

[0115] In another specific embodiment of this disclosure, reference is made to Figures 6 to 9The transmission assembly 5 is located in the first side direction (Y1 direction) of the cleaning assembly 2, and the blocking member 324 is disposed at the end of the movable seat 32 in the first side direction (Y1 direction). During the movement of the cleaning assembly 2 away from the working surface (Z1 direction), the movable seat 32 drives the blocking member 324 to extend in the first side direction (Y1 direction) onto the path of the transmission assembly 5 moving away from the working surface (Z1 direction). Specifically, the blocking member 324 can be a part fixedly disposed at the Y1 direction end of the movable seat 32, or it can be integrally formed with the movable seat 32.

[0116] In the normal cleaning state without lifting, the blocking member 324 is in a retracted state, and the upper movement path of the transmission component 5 is not obstructed. As mentioned above, the cleaning component 2 can float up and down during the cleaning process. During the floating process, the upper part of the transmission component 5 is never obstructed, so the covering component 4 can remain in the second position. During the process of the motion component 3 driving the cleaning component 2 to lift upward, the movable seat 32 can move in the Y1 direction, thereby driving the blocking member 324 to move in the Y1 direction as well. When the cleaning component 2 is lifted to the first preset position, or before it is lifted to the first preset position, the blocking member 324 is at least partially located directly above the transmission component 5, so that the transmission component 5 can abut against the blocking member 324 when it reaches the first preset position. During the process of continuing to lift upward from the first preset position, the movable seat 32 will continue to drive the blocking member 324 to move in the Y1 direction, and the transmission component 5 will always abut against the blocking member 324 during this process.

[0117] Furthermore, in one specific embodiment of this disclosure, reference is made to... Figure 6 , Figure 8 and Figure 9 An extension opening 103 for the blocking member 324 to pass through is provided at the end of the first side of the mounting base 10 in the Y1 direction, and an extension opening 102 for the transmission assembly 5 to pass through is provided on the bottom wall of the mounting base 10 corresponding to the position of the transmission assembly 5. When not being lifted, the blocking member 324 is in a retracted state before reaching the extension opening 102, and the upward path of the transmission assembly 5 is not blocked; during the lifting process to the first preset position, the blocking member 324 gradually moves in the Y1 direction to a position covering the position directly above the extension opening 102, and the transmission assembly 5 rises so that its top enters the extension opening 102; when lifted to the first preset position, the transmission assembly 5 penetrating the extension opening 102 abuts against the bottom surface of the blocking member 324; when continuing to lift upward from the first preset position, the position of the transmission assembly 5 remains unchanged, and the blocking member 324 continues to move in the Y1 direction; when lifted to the highest position, at least part of the blocking member 324 extends outward through the extension opening 103.

[0118] In one embodiment of this disclosure, when the cleaning component 2 moves towards the working surface (Z2 direction) to the second preset position, the external force on the transmission component 5 is removed, and the covering component 4 moves from the first position to the second position under the action of the elastic force. As mentioned above, the covering component 4 can be held in the second position under the action of the elastic component 6. Under the action of the transmission component 5, the covering component 4 overcomes the elastic force and rotates to the first position, during which the elastic component 6 accumulates elastic force. When the cleaning component 2 descends to the second preset position, the cleaning component 2 is close to the working surface, the external force on the transmission component 5 is removed, and the elastic component 6 can release its accumulated elastic force, so that the covering component 4 quickly returns to the second position under the action of the elastic force.

[0119] It should be noted that the first preset position and the second preset position refer to the height position of the cleaning component 2 relative to the working surface. In a specific embodiment of this disclosure, the second preset position can be the same as the first preset position. For example, in an embodiment where the blocking member 324 is a blocking rod, blocking block, or other structure fixed to the body 1, the position of the blocking member 324 remains unchanged, and the height position of the lower end face of the blocking member 324 is both the second preset position and the first preset position. When the cleaning component 2 drives the transmission component 5 to rise to this height position, it abuts against the transmission component 5 (at this moment, the blocking member 324 has not yet applied external force to the transmission component 5; the transmission component 5 only begins to be subjected to external force when the cleaning component 2 continues to rise), and when the cleaning component 2 descends back to this height position, the transmission component 5 is no longer subjected to external force. Therefore, during the continued descent, the covering component 4 can be reset from the first position to the second position under the action of elastic force.

[0120] In another specific embodiment of this disclosure, the second preset position may be different from the first preset position. For example, in the embodiment where the blocking member 324 is disposed on the movable seat 32, the blocking member 324 may have already reached the position "at least partially above the transmission component 5" before the cleaning component 2 is raised to the first preset position. The cleaning component 2 needs to continue to drive the transmission component 5 to rise until it reaches the first preset position, at which point the transmission component 5 comes into contact with the blocking member 324. During the descent, when the cleaning component 2 reaches the first preset position, the blocking member 324 remains in contact with the transmission component 5, and as the cleaning component 2 continues to descend from the first preset position, it continues to apply external force to the transmission component 5; until it descends to the second preset position, the blocking member 324 retracts under the action of the movable seat 32, and the area directly above the transmission component 5 is no longer blocked. Only then is the external force on the transmission component 5 removed, and the covering component 4 can be reset from the first position to the second position under the action of elastic force.

[0121] In one embodiment of this disclosure, reference is made to Figures 1 to 3The cover assembly 4 includes a first cover 41 movably connected to the cleaning assembly 2, and a second cover 42 disposed on the upper cover assembly 12 and located behind the cleaning assembly 2. The first cover 41 and the second cover 42 are connected by a guide mechanism. The first cover 41 is configured to move to a second position retracted into the gap between the second cover 42 and the cleaning assembly 2, and to move relative to the second cover 42 to a first position disengaged from the gap. Both the first cover 41 and the second cover 42 include a main body portion 401 extending along the axial direction (Y-axis direction) of the cleaning assembly 2, while the mounting portion 402 may be disposed only on the first cover 41. The first cover 41 can, under the action of the elastic component 6, move the second cover 42 together to maintain it in the second position, and under the action of the transmission component 5, move the second cover 42 to the first position.

[0122] refer to Figure 12 When in the second position, the first cover 41 and the second cover 42 overlap, thereby allowing the cover assembly 4 to be stored in the receiving space 13 with a smaller overall volume. When in the first position, the first cover 41 moves relative to the second cover 42, thereby significantly increasing the covering area of ​​the cover assembly 4 directly below the cleaning assembly 2, improving the covering effect, and further reducing the risk of soiling the carpet after the cleaning assembly 2 is raised.

[0123] In one embodiment of this disclosure, such as Figure 2 As shown, the second cover 42 is configured to be connected to the upper cover assembly 12 via a flexible connector 11. The first cover 41 is configured to move the second cover 42 by a predetermined displacement against the elastic force of the flexible connector 11 during movement to the first position. Specifically, the flexible connector 11 can be made of a waterproof and flexible material such as silicone or rubber. When in the second position, the flexible connector 11 can be folded inwards and stored together with at least part of the cover assembly 4 in the receiving space 13.

[0124] When in the first position, the front end (X1 direction) of the second cover 42 is connected to the first cover 41, and the rear end (X2 direction) is connected to the upper cover assembly 12 via the flexible connector 11. The first cover 41 can move the second cover 42 to the position where the flexible connector 11 is taut. This makes the two ends of the cover assembly 4 in the first position balanced by forces. One end is subjected to the elastic force of the elastic component 6, and the other end is subjected to the tension of the flexible connector 11. This allows the cover assembly 4 in the first position to remain stable and not to sway relative to the body 1.

[0125] In one embodiment of this disclosure, reference is made to Figure 6 and Figure 12One of the first cover 41 and the second cover 42 is provided with a second flange 411, and the other is provided with a guide groove 421 that mates with the second flange 411. In this embodiment, the second flange 411 is provided on the first cover 41, and the guide groove 421 is provided on the second cover 42. The second flange 411 extends into the guide groove 421, thereby driving the second cover 42 to move through the first cover 41. Specifically, the shape of the guide groove 421 can be adapted to the movement trajectory of the second flange 411. In the embodiment where the cover assembly 4 is hinged to the cleaning assembly 2, the guide groove 421 can be constructed as an arc.

[0126] The guide groove 421 has a first end and a second end. In the second position, the second flange 411 is located at the first end of the guide groove 421. Under the action of the transmission assembly 5, the first cover 41 moves to the first position. During this process, the second flange 411 moves along the guide groove 421 to the second end, and after reaching the second end, it abuts against the inner wall of the second end of the guide groove 421, thereby driving the second cover 42 to move together to the first position. In the first position, the second flange 411 is located at the second end of the guide groove 421. Under the action of the elastic assembly 6, the first cover 41 moves to the second position. During this process, the second flange 411 moves along the guide groove 421 to the first end, and after reaching the first end, it abuts against the inner wall of the first end of the guide groove 421, thereby driving the second cover 42 to move together to the second position.

[0127] In one specific embodiment of this disclosure, such as Figure 4 As shown, two second flanges 411 can be provided, symmetrically arranged at opposite ends of the first cover 41. Correspondingly, two guide grooves 421 can also be provided, symmetrically arranged at opposite ends of the second cover 42. This achieves dual-sided synchronous guidance between the two covers, improving the stability of the transmission engagement.

[0128] According to a second aspect of this disclosure, a cleaning device is also provided, comprising: a cleaning component 2, a covering component 4, and a transmission component 5. The cleaning component 2 is used to clean a work surface and is configured to move in a direction away from or towards the work surface; the covering component 4 is movably connected to the cleaning component 2 and is configured to follow the cleaning component 2 in the direction away from or towards the work surface; the covering component 4 is movable relative to the cleaning component 2 between a first position and a second position; the transmission component 5 is used to drive the covering component 4 to move relative to the cleaning component 2. When the cleaning component 2 is in a state away from the work surface, the covering component 4 is located in the first position, with at least a portion of the covering component 4 located between the cleaning component 2 and the work surface; when the cleaning component 2 is in a state close to or in contact with the work surface, the covering component 4 is located in the second position. This cleaning device can be applied to the cleaning equipment described above, and the specific structure and working principle of this cleaning device are completely consistent with the cleaning device of the cleaning equipment described above, and will not be repeated here.

[0129] According to a third aspect of this disclosure, a cover assembly 4 is also provided, movably connected to a cleaning assembly 2. The cover assembly 4 includes a first cover 41 and a second cover 42. The first cover 41 is configured to move relative to the cleaning assembly 2 between a first position and a second position. The second cover 42 is configured to cooperate with the first cover 41 via a guide mechanism and is configured to move relative to the cleaning assembly 2 under the driving force of the first cover 41. In the first position, at least a portion of the first cover 41 is located between the cleaning assembly 2 and the working surface. In the second position, at least a portion of the first cover 41 is configured to be housed in the gap between the second cover 42 and the cleaning assembly 2. This cover assembly 4 can be applied to the cleaning device described above, and the specific structure and working principle of the cover assembly 4 can be completely consistent with the cleaning device of the cleaning equipment described above, and will not be repeated here. In addition, the external force driving the movement of the first cover 41 can come from the transmission assembly 5, or other types of driving structures can be additionally provided for the first cover 41, which is not limited in this disclosure.

[0130] In one embodiment of this disclosure, a first cover 41 is movably connected to a cleaning component 2, which is mounted below an upper cover assembly 12, and a second cover 42 is disposed on the upper cover assembly 12. A portion of the upper cover assembly 12 is configured to extend to the rear side of the cleaning component 2 and enclose a receiving space 13 with the cleaning component 2; in the second position, at least a portion of the first cover 41 is housed within the receiving space 13. Specifically, in the second position, the first cover 41 and the second cover 42 overlap, thereby allowing the cover assembly 4 to be housed as a whole within the receiving space 13 with a relatively small volume. In the first position, the first cover 41 moves relative to the second cover 42, thereby significantly increasing the covering area of ​​the cover assembly 4 directly below the cleaning component 2, improving the covering effect, and further reducing the risk of carpet contamination after the cleaning component 2 is raised.

[0131] In one embodiment of this disclosure, the second cover 42 is configured to be connected to the upper cover assembly 12 via a flexible connector 11, and the first cover 41 is configured to move the second cover 42 by a predetermined displacement against the elastic force of the flexible connector 11 during movement to the first position. Specifically, the flexible connector 11 can be made of a waterproof and flexible material such as silicone or rubber. When in the first position, the relatively forward end of the second cover 42 is connected to the first cover 41, and the relatively rearward end is connected to the upper cover assembly 12 via the flexible connector 11. The first cover 41 can move the second cover 42 to a position where the flexible connector 11 is taut, which balances the forces at both ends of the cover assembly 4 in the first position.

[0132] In one embodiment of this disclosure, one of the first cover 41 and the second cover 42 is provided with a second flange 411, and the other is provided with a guide groove 421 that mates with the second flange 411. In this embodiment, the second flange 411 is provided on the first cover 41, and the guide groove 421 is provided on the second cover 42. The second flange 411 extends into the guide groove 421, thereby driving the second cover 42 to move via the first cover 41. Specifically, the shape of the guide groove 421 can be adapted to the movement trajectory of the second flange 411. In embodiments where the cover assembly 4 is hinged to the cleaning assembly 2, the guide groove 421 can be constructed as an arc.

[0133] Application scenarios

[0134] In a home cleaning scenario, the cleaning device is a robot vacuum and mop. When cleaning the living room, the robot vacuum and mop will pass over a carpet in its cleaning path. To prevent the carpet from getting dirty, when the robot vacuum and mop moves over the carpet, the cleaning component 2 can be lifted upwards (in the Z1 direction) relative to the body 1 under the action of the motion component 3.

[0135] Specifically, the operation of the drive component 31 causes the drive gear 311 to rotate, thereby driving the movable seat 32 to move in the Y1 direction via the rack 321. When the driving force provided by the drive component 31 reaches the lifting force required for the connecting arm 23 to climb the guide surface 322, the guide surface 322 on the movable seat 32 can scoop up the roller 232, causing the roller 232 to roll uphill along the guide surface 322, and driving the cleaning component 2 to rise via the lifting rod 231. A blocking component 324 is provided at the Y1 end of the movable seat 32. During the lifting process, the blocking component 324 can move in the Y1 direction along with the movable seat 32. When the cleaning component 2 is raised to the first preset position, or before it is raised to the first preset position, the blocking component 324 is at least partially located directly above the transmission component 5.

[0136] In the initial lifting stage, the cleaning component 2, the covering component 4, and the transmission component 5 rise synchronously without relative movement between them. Until they reach the first preset position, the transmission component 5 comes into contact with the blocking member 324, thus preventing the transmission component 5 from rising further. During the upward lifting process from the first preset position, the cleaning component 2 drives the covering component 4 to continue rising, while the transmission component 5 remains stationary due to the contact with the blocking member 324. That is, the transmission component 5 moves relative to the cleaning component 2 and the covering component 4, and the covering component 4 is subjected to a force from the transmission component 5, thereby overcoming the elastic force of the elastic component 6 and beginning to move towards the first position.

[0137] When in the first position, at least part of the covering component 4 is located between the cleaning component 2 and the carpet, thus physically isolating the cleaning component 2 from the carpet and preventing the cleaning component 2 from contaminating the carpet. Specifically, when the cleaning component 2 is raised and dripping water, the wastewater can be caught by the covering component 4; for long-pile carpets, even if the cleaning component 2 is not raised high enough, the long pile will only come into contact with the clean bottom surface of the covering component 4, and will not come into contact with the cleaning component 2.

[0138] When the robot vacuum and mop moves from the carpet back to the ground, the cleaning component 2 can be lowered (in the Z2 direction) relative to the body 1 under the action of the motion component 3. The drive component 31 can provide a force to the movable seat 32 to reset in the Y2 direction. During the movement of the movable seat 32 relative to the cleaning component 2 in the Y2 direction, the roller 232 can roll downhill along the guide surface 322 under the gravity of the cleaning component 2 and the connecting arm 23, and drive the cleaning component 2 to descend through the lifting rod 231.

[0139] During the descent, the blocking member 324 can move in the Y2 direction along with the movable seat 32. When the cleaning component 2 descends to the second preset position, the blocking member 324 retracts so that the top of the transmission component 5 is not blocked, thereby canceling the external force on the transmission component 5. The covering component 4 can be reset from the first position to the second position under the action of the elastic force of the elastic component 6.

[0140] This disclosure achieves linkage between the cleaning component 2 and the covering component 4 by setting up a transmission component 5: when the cleaning component 2 is raised, the covering component 4 moves to a first position, thereby blocking the cleaning component 2 from the working surface; when the cleaning component 2 is lowered, the covering component 4 can return to a second position, allowing the cleaning component 2 to make normal contact with the working surface, thus continuing subsequent cleaning work. Through this linkage design, there is no need to set up an additional drive source for the movement of the covering component 4, which helps to simplify the structure of the sweeping and mopping robot and reduce costs.
