Description

Technical Field

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

[0002] As the economy develops and people's living standards gradually improve, their requirements for environmental hygiene are also increasing. To save manpower, a variety of cleaning equipment has emerged on the market. Currently, when cleaning equipment works close to the wall, it is often difficult to achieve zero-distance contact, resulting in cleaning dead corners. For example, in a home setting, stains may still remain in the baseboard area, leading to a poor user experience.

[0003] In existing technologies, a motor can be used to drive the cleaning mechanism to move to the outside of the machine body, thereby achieving the purpose of mopping to the edge. However, when moving close to the edge, the cleaning mechanism will rub against the wall, causing continuous resistance to the cleaning equipment during its movement. This can easily lead to wear and tear on the cleaning mechanism and may even scratch the wall. Utility Model Content

[0019] In one embodiment of this disclosure, the cleaning mechanism is provided with a lifting component, and the cleaning mechanism is configured to be supported on the movable seat by the lifting component; wherein, an inclined guide surface is provided on the movable seat at a position in the direction of the second side of the lifting component; the lifting component is configured to cooperate with the guide surface under the action of an elastic component, and the elastic force of the elastic component is configured to be less than the lifting force of the lifting component moving upward along the guide surface.

[0020] In one embodiment of this disclosure, when in the first position, the movable seat is configured such that, during movement in the direction of the first side, the lifting assembly is pressed along the guide surface to lift the cleaning mechanism relative to the body, and when the movable seat is reset, the lifting assembly overcomes the elastic force of the elastic component under its own weight to lower the cleaning mechanism relative to the body.

[0021] In one embodiment of this disclosure, the movable seat is provided with a floating groove, which is configured to extend on the movable seat from the position of the guide surface toward the direction of the first side; the lifting assembly is configured to pass through the floating groove and support the movable seat; one end of the floating groove on its first side is the limiting part.

[0022] In one embodiment of this disclosure, the body is provided with a mounting base, the mounting base is provided with a through groove, the cleaning mechanism is configured to be located at the bottom of the mounting base, and the motion mechanism is configured to be located at the top of the mounting base; the lifting assembly is configured to be carried on the movable seat after the cleaning mechanism passes through the through groove and the floating groove.

[0023] In one embodiment of this disclosure, the two ends of the through groove are respectively referred to as the first end located on the first side and the second end located on the second side; when in the first position, the lifting assembly is restricted to the first end of the through groove, and the movable seat is configured such that during the movement in the direction of the first side, the lifting assembly is pressed along the guide surface to drive the cleaning mechanism to rise relative to the body, and when the movable seat is reset, the lifting assembly overcomes the elastic force of the elastic component under its own weight to drive the cleaning mechanism to fall relative to the body.

[0024] In one embodiment of this disclosure, the lifting assembly includes a lifting rod, on which rollers are provided for engaging with the guide surface.

[0025] In one embodiment of this disclosure, a first mounting hook is provided on the lifting assembly, and a second mounting hook is provided on the movable seat; in the lateral direction of the cleaning equipment, the opposite ends of the elastic component are respectively connected to the first mounting hook and the second mounting hook.

[0026] According to a second aspect of this disclosure, a cleaning device is provided, comprising:

[0027] Organism;

[0028] A cleaning mechanism configured to clean a work surface; wherein the cleaning mechanism is provided with a rolling part;

[0029] A motion mechanism is disposed on the body, and a cleaning mechanism is configured to be floatingly connected to the motion mechanism via an elastic component; the motion mechanism is configured to drive the cleaning mechanism to move relative to the body between a first position and a second position;

[0030] When in the second position, the cleaning mechanism is configured to extend outward relative to the body so that the rolling part rolls in coordination with the obstacle; during the movement of the cleaning device, the cleaning mechanism tends to move in the direction of the first position under the action of an external force.

[0031] According to a third aspect of this disclosure, a cleaning device is provided, comprising:

[0032] Organism;

[0035] In the second position, the cleaning mechanism is configured to extend outward relative to the body so that the rolling part rolls in conjunction with the obstacle.

[0036] One beneficial effect of this disclosure is that by floatingly connecting the cleaning mechanism and the motion mechanism through an elastic component, the cleaning mechanism can maintain a second position extending outward relative to the main body during edge cleaning, thereby reaching into cleaning dead corners, increasing the cleaning coverage area, and achieving comprehensive cleaning. Furthermore, when the cleaning mechanism collides with an obstacle such as a wall, it can adaptively retract inward. After the external force is removed, the cleaning mechanism has a tendency to move back to the second position under the action of elasticity, thereby extending outward again to allow the rolling part to roll and engage with the obstacle, achieving complete edge cleaning. During the edge-cleaning process, the rolling part maintains contact with obstacles such as walls, thus avoiding the problem of continuous resistance to the cleaning mechanism. The cleaning mechanism will not scrape against the wall, reducing wear and tear and improving the user experience.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] This embodiment provides a cleaning device, which can be a handheld cleaning device, such as a handheld cleaning machine, 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 robotic vacuum cleaner, robotic mop, or a combined sweeping and mopping robot, used to clean work surfaces such as floors, sofas, and carpets.

[0059] refer to Figure 1 and Figure 3Taking this embodiment of the cleaning equipment as an example of a sweeping and mopping robot, the cleaning equipment disclosed herein includes a body 1, a cleaning mechanism 2, and a motion mechanism 3. The body 1 serves as the basic installation structure for the cleaning equipment. Wheels are installed on the body 1, enabling the robot to move independently on the work surface. The cleaning mechanism 2 is configured to clean the work surface. Specifically, the cleaning mechanism 2 can be components such as a roller, a roller brush, a mopping pad, or a floor brush. Taking a roller as an example, by applying water to the roller, wet mopping of the work surface can be achieved, thereby achieving a good cleaning effect.

[0060] The motion mechanism 3 is mounted on the body 1, and the cleaning mechanism 2 is configured to float and connect to the motion mechanism 3 via an elastic component 31. The motion mechanism 3 is configured to drive the cleaning mechanism 2 to move relative to the body 1 between a first position and a second position. Figure 1 As shown, the forward direction of the cleaning equipment is denoted as "front," and the two sides of the cleaning equipment in the lateral direction are denoted as the first side S1 and the second side S2, respectively. (Reference) Figure 1 In the view direction, the top is marked as the forward direction of the cleaning equipment, the left side is the first side S1, and the right side is the second side S2. The motion mechanism 3 can drive the cleaning mechanism 2 to move to the second position in the direction of the second side S2, and to move to the first position in the direction of the first side S1.

[0061] When the cleaning mechanism 2 is in the first position, its edge can be located within the edge projection area of ​​the body 1. This makes the overall size of the cleaning equipment smaller, easier to store, and less prone to collisions during operation. When the cleaning mechanism 2 is in the second position, it is configured to extend outward relative to the body 1. This allows the cleaning mechanism 2 to have a larger cleaning range, thus cleaning hard-to-reach corners that are difficult to reach in the first position, achieving thorough cleaning.

[0062] In a practical cleaning scenario, the cleaning equipment performs cleaning operations in open areas as well as along walls and furniture edges. When cleaning in open areas, the cleaning mechanism 2 can remain in the first position, eliminating the need for the motion mechanism 3 and thus saving energy. When cleaning along edges, the motion mechanism 3 moves the cleaning mechanism 2 to the second position, extending into the cleaning dead zones between the machine body 1 and the edge, thereby expanding the cleaning range and eliminating blind spots for thorough cleaning. In another specific implementation, the cleaning mechanism 2 can be kept in the second position throughout the entire cleaning process, achieving wide-area cleaning throughout, improving cleaning efficiency, and facilitating the optimization of the cleaning path.

[0063] However, the cleaning mechanism 2, located in the second position, is prone to collisions and scrapes against obstacles, and cannot retract in time after an impact, potentially causing the cleaning robot to get stuck at the obstacle. Furthermore, during edge cleaning, the side of the cleaning mechanism 2 may scrape against the wall, causing continuous resistance during movement, leading to wear and tear on the cleaning mechanism 2 and possibly damaging the wall. To solve these technical problems, the cleaning mechanism 2 of this disclosure is provided with a rolling part 21, which can specifically be a component with a rolling function such as a ball bearing or a small wheel.

[0064] In one embodiment of this disclosure, such as Figure 2 and Figure 10 As shown, at least one rolling part 21 is provided, and the at least one rolling part 21 is configured to protrude from the edge of the cleaning mechanism 2 on the side facing the second position direction. The rolling part 21 is provided on the second side S2 of the cleaning mechanism 2, and at least partially protrudes from the edge of the second side S2 of the cleaning mechanism 2. Therefore, when the cleaning device cleans along the edge, the side of the cleaning mechanism 2 will not directly contact the obstacle (e.g., a wall), but will achieve rolling engagement with the obstacle (e.g., a wall) through the rolling part 21, thereby reducing the frictional resistance between the cleaning device and the obstacle surface. This disclosure, by providing the rolling part 21, avoids the problem of continuous resistance to the cleaning mechanism 2, prevents the cleaning mechanism 2 from scraping against the wall, reduces wear and tear on the cleaning mechanism 2, and improves the user experience.

[0065] Figure 2 The dashed line in the middle indicates the location of the obstacle (e.g., a wall). The rolling part 21 can maintain line contact with the wall, while the side of the cleaning mechanism 2 does not contact the wall, leaving only a very small gap between them. In a specific embodiment of this disclosure, the rolling part 21 protrudes from the edge of the cleaning mechanism 2 by no more than 1 mm, that is, the gap between the cleaning mechanism 2 and the wall is no more than 1 mm. This greatly reduces the cleaning dead zone area and increases the cleaning coverage area of ​​the cleaning equipment.

[0066] In the second position, the cleaning mechanism 2 is configured to extend outward relative to the body 1 so that the rolling part 21 rolls and engages with the obstacle. During the movement of the cleaning device, the cleaning mechanism 2 tends to move towards the direction of the first position under the action of an external force, and when the external force is removed, the cleaning mechanism 2 tends to move towards the second position under the action of the elastic component 31, thus enabling the rolling part 21 to move again to roll and engage with the obstacle. This disclosure uses the elastic component 31 to float the cleaning mechanism 2 and the motion mechanism 3. When the cleaning mechanism 2 collides with an obstacle, such as a wall, the cleaning mechanism 2 can adaptively retract inward (i.e., move towards the direction of the first position), thereby preventing the cleaning mechanism 2 from being stuck by the obstacle. After the external force is removed, the cleaning mechanism 2 tends to move towards the second position under the elastic force of the elastic component 31, thus extending outward again to allow the rolling part 21 to roll and engage with the obstacle, achieving complete edge cleaning. The elastic component 31 can accurately adjust the relative position of the cleaning mechanism 2 and the body 1 according to the magnitude of the external force exerted by the obstacle. During the edge cleaning process, the rolling part 21 can maintain rolling cooperation with the obstacle, thereby ensuring complete edge contact.

[0067] In one embodiment of this disclosure, the forward direction of the cleaning equipment is referred to as "forward," and reference is made to... Figure 10 The system includes at least one rolling part 21, which is configured to protrude from the front edge of the cleaning mechanism 2 and from the edge of the cleaning mechanism 2 facing the second position direction. For example, the rolling part 21 can be positioned at the corner between the front and second side S2 of the cleaning mechanism 2. As mentioned above, the rolling part 21 protrudes from the edge of the second side S2 of the cleaning mechanism 2, thereby avoiding frictional contact between the side of the cleaning mechanism 2 and the surface of the obstacle, reducing resistance during movement. Furthermore, by simultaneously configuring the rolling part 21 to protrude from the front edge of the cleaning mechanism 2, when an obstacle appears in front, the front wall of the cleaning mechanism 2 protruding from the body 1 will not directly collide with the obstacle, but can be buffered by the rolling part 21. In addition, the rolling part 21 can reduce the friction between the cleaning mechanism 2 and the obstacle in front, thereby helping the cleaning equipment to turn around and avoid getting stuck at the obstacle.

[0068] In one embodiment of this disclosure, the rolling part 21 is disposed on the sidewall of the cleaning mechanism 2 facing the second position direction; and / or, the rolling part 21 is disposed on the top end face of the cleaning mechanism 2. (See reference...) Figure 9 In this embodiment, two rolling parts 21 may be provided, and the two rolling parts 21 may be spaced apart on the second side S2 sidewall of the cleaning mechanism 2. In another specific embodiment, refer to... Figure 10 The rolling part 21 can be installed on the top end face of the cleaning mechanism 2 at the corner between the front side and the second side S2 (i.e., Figure 10 The rolling part 21 (located at the upper right corner of the top surface of the cleaning mechanism 2 shown) is prone to wear after long-term use, so the user needs to replace it himself. The rolling part 21 installed on the top surface makes it easy for the user to disassemble and assemble it himself.

[0069] In one embodiment of this disclosure, reference is made to Figure 3 , Figure 6 and Figure 8 The motion mechanism 3 includes a drive assembly 32 and a movable seat 33 that guides and cooperates with the body 1. The cleaning mechanism 2 is configured to float and connect to the movable seat 33 via an elastic component 31. The movable seat 33 is configured to be controlled by the drive assembly 32 to move the cleaning mechanism 2 to a second position in the direction of the second side S2 via the elastic component 31, and to move to a first position in the direction of the first side S1. Specifically, refer to... Figure 4 and Figure 7 The drive assembly 32 can be a motor that is fixed relative to the body 1, and a drive gear 321 can be provided on its output shaft; a rack 334 that meshes with the drive gear 321 can be provided on the movable seat 33. When the drive motor 32 is working, the drive gear 321 rotates, thereby driving the movable seat 33 to move relative to the body 1 through the rack 334.

[0070] The movable seat 33 and the cleaning mechanism 2 are floatingly connected via an elastic component 31. In one specific embodiment of this disclosure, refer to... Figures 3 to 5 The cleaning mechanism 2 is equipped with a lifting assembly 22, and the cleaning mechanism 2 is configured to be supported on a movable seat 33 via the lifting assembly 22. The movable seat 33 is provided with a floating groove 333, and the body 1 is provided with a mounting base 10, which is provided with a through groove 101. The cleaning mechanism 2 is configured to be located at the bottom of the mounting base 10, and the motion mechanism 3 is configured to be located at the top of the mounting base 10. The lifting assembly 22 is configured to pass through the through groove 101 and the floating groove 333 of the cleaning mechanism 2 and then support the movable seat 33. The lifting assembly 22 includes a lifting rod 221, which can be a pin. The head of the pin is located above the movable seat 33, and the tail extends downward through the floating groove 333 and the through groove 101, and is fixedly connected to the top of the cleaning mechanism 2.

[0071] Mounting base 10 can be a support component installed on the machine body 1. Cleaning mechanism 2 is located below mounting base 10, thus exposed outside the machine body 1, enabling cleaning of the working surface. Motion mechanism 3 is mounted above mounting base 10, thus concealed inside the machine body 1. (Reference) Figure 3 and Figure 4The motion mechanism 3 may also include a fixed base 34, which is fixedly mounted on the mounting base 10. The movable base 33 is movably mounted above the fixed base 34. A sliding groove 341 is provided on the fixed base 34 corresponding to the floating groove 333 and the through groove 101. The tail of the lifting rod 221 can sequentially pass through the floating groove 333, the sliding groove 341, and the through groove 101, thereby being fixedly connected to the top of the cleaning mechanism 2. Figure 3 As shown, the top of the cleaning mechanism 2 may be provided with a mounting column 23 for mounting the lifting rod 221. The bottom of the mounting column 23 is fixed to the top surface of the cleaning mechanism 2 and can extend upward to sequentially pass through the through groove 101, the sliding groove 341 and the floating groove 333. The lifting rod 221 can be nailed into the mounting column 23, thereby connecting the cleaning mechanism 2.

[0072] In one embodiment of this disclosure, two lifting components 22 may be separately provided. Correspondingly, two floating grooves 333 are provided on the movable seat 33, two sliding grooves 341 are provided on the fixed seat 34, two through grooves 101 are provided on the mounting seat 10, and two mounting columns 23 are provided on the top of the cleaning mechanism 2. The cleaning mechanism 2 is relatively heavy when wet. If only a single lifting component 22 is used, the connection may be unstable and easily damaged, making it impossible to smoothly drive the cleaning mechanism 2. This disclosure enhances the stability of the installation of the lifting component 22 and the cleaning mechanism 2 by providing two lifting components 22.

[0073] In one embodiment of this disclosure, reference is made to Figures 3 to 5 An elastic component 31 is disposed between a movable seat 33 and a lifting component 22. A first mounting hook 223 is provided on the lifting component 22, and a second mounting hook 335 is provided on the movable seat 33. In the lateral direction of the cleaning equipment, the opposite ends of the elastic component 31 are connected to the first mounting hook 223 and the second mounting hook 335, respectively. (Reference) Figure 3 In the view orientation, the flexible component 31 can be positioned between the movable seat 33 and the lifting component 22 on the right, such as... Figure 5 As shown, the first mounting hook 223 is located on the right side of the lifting assembly 22. The end of the elastic component 31 in the direction of the first side S1 (left side) is connected to the first mounting hook 223, and the end of its second side S2 (right side) is connected to the second mounting hook 335. Specifically, the elastic component 31 can be a tension spring, with its left and right ends connected to the first mounting hook 223 and the second mounting hook 335, respectively. When the lifting assembly 22 moves relative to the movable seat 33, the tension spring will deform. This achieves a floating connection between the lifting assembly 22 and the movable seat 33, and further achieves a floating connection between the movable seat 33 and the cleaning mechanism 2 via the elastic component 31.

[0074] In one embodiment of this disclosure, the elastic force of the elastic component 31 is configured to be greater than the resistance to the movement of the cleaning mechanism 2 in the direction of the second position. Under the action of the drive component 32, the movable seat 33 can move in the direction of the second position. At this time, the movable seat 33 pulls the elastic component 31. Since the elastic force of the elastic component 31 is greater than the resistance to the movement of the cleaning mechanism 2 in the direction of the second position, the elastic component 31 can pull the lifting component 22 and the cleaning mechanism 2 connected thereto to move together in the direction of the second side S2 to the second position. During this movement, there is basically no relative movement between the movable seat 33 and the cleaning mechanism 2.

[0075] Similarly, under the action of the drive component 32, the movable seat 33 can move towards the first position. At this time, the movable seat 33 pushes the elastic component 31. Since the elastic force of the elastic component 31 is greater than the resistance of the cleaning mechanism 2 to move towards the first position, the elastic component 31 can push the lifting component 22 and the cleaning mechanism 2 connected to it to move together towards the first side S1 to the first position. During this movement, there is basically no relative movement between the movable seat 33 and the cleaning mechanism 2.

[0076] In one embodiment of this disclosure, reference is made to Figure 4 and Figure 7 A limiting part 331 is provided on the movable seat 33. The cleaning mechanism 2 is configured to cooperate with the limiting part 331 after moving a predetermined distance in the direction of the first side S1 under external force. When the cleaning mechanism 2 is subjected to an external force from an obstacle, the cleaning mechanism 2 can drive the lifting assembly 22 to move relative to the movable seat 33 in the direction of the first side S1. At this time, the lifting rod 221 of the lifting assembly 22 and the mounting column 23 on the cleaning mechanism 2 can slide in the floating groove 333, the sliding groove 341 and the through groove 101, and the first mounting hook 223 can pull the elastic component 31 to deform. Figure 7 As shown, the maximum distance that the cleaning mechanism 2 can move relative to the movable seat 33 in the first side S1 direction is the predetermined distance M. When the movement distance reaches the predetermined distance M, the lifting component 22 will abut against the limiting part 331, thereby preventing the cleaning mechanism 2 from continuing to move in the first side S1 direction.

[0077] In one specific embodiment of this disclosure, the cleaning mechanism 2 can extend outward relative to the body 1 by a distance (i.e., the distance between the first position and the second position) of not less than 10 mm. Based on this, the predetermined distance can be set to not less than 10 mm. In this embodiment, the predetermined distance can be substantially consistent with the distance between the first position and the second position. In this way, under the action of an obstacle, the cleaning mechanism 2, which was originally located in the second position, can retract inward to the first position at most, thus avoiding being stuck by the obstacle.

[0078] In one embodiment of this disclosure, an inclined guide surface 332 is provided on the movable seat 33 in the direction of the second side S2 of the lifting assembly 22. The lifting assembly 22 is configured to cooperate with the guide surface 332 under the action of the elastic component 31, and the elastic force of the elastic component 31 is configured to be less than the lifting force required for the lifting assembly 22 to move upward along the guide surface 332. Specifically, a roller 222 for cooperating with the guide surface 332 is provided on the lifting rod 221. Under the elastic force of the elastic component 31 alone, the roller 222 cannot roll upward along the guide surface 332. In this embodiment, the elastic force of the elastic component 31 is approximately 2N, while the lifting force required for the roller 222 to climb the slope on the guide surface 332 is approximately 40N. This allows the guide surface 332 to limit the lifting assembly 22 in the direction of the second side S2, and the lifting assembly 22 can be held at the bottom of the slope of the guide surface 332 under the elastic traction of the elastic component 31 when no external force is applied.

[0079] Furthermore, such as Figure 7 As shown, the floating groove 333 is constructed to extend from the guide surface 332 towards the first side S1 on the movable seat 33, with a limiting part 331 at one end of the floating groove 333 on the first side S1. The length of the floating groove 333 limits the movable distance of the lifting rod 221, and the length of the floating groove 333 can be the aforementioned predetermined distance M. When no external force is applied, the lifting rod 221 can remain at the end position of the second side S2 of the floating groove 333, i.e., at the bottom of the slope of the guide surface 332; when subjected to external force, the lifting rod 221 can move at most within the floating groove 333 towards the first side S1 until it engages with the limiting part 331, i.e., it moves to the end position of the first side S1 of the floating groove 333.

[0080] In one embodiment of this disclosure, when in the first position, the movable seat 33 is configured such that, during movement toward the first side S1, the lifting component 22 is pressed along the guide surface 332 to lift the cleaning mechanism 2 relative to the body 1, and when the movable seat 33 returns to its original position, the lifting component 22, under its own weight, overcomes the elastic force of the elastic component 31 to lower the cleaning mechanism 2 relative to the body 1. Specifically, the two ends of the through groove 101 are respectively referred to as the first end located on the first side S1 and the second end located on the second side S2; when in the first position, the lifting component 22 is confined to the first end of the through groove 101, and the movable seat 33 is configured such that, during movement toward the first side S1, the lifting component 22 is pressed along the guide surface 332 to lift the cleaning mechanism 2 relative to the body 1, and when the movable seat 33 returns to its original position, the lifting component 22, under its own weight, overcomes the elastic force of the elastic component 31 to lower the cleaning mechanism 2 relative to the body 1.

[0081] The lifting assembly 22 can lift the cleaning mechanism 2 upward under the action of the motion mechanism 3. Specifically, the drive assembly 32 can provide a force to the movable seat 33 in the direction of the first side S1. When this driving force reaches the lifting force required for the lifting assembly 22 to climb the guide surface 332, the movable seat 33 can move relative to the cleaning mechanism 2 in the direction of the first side S1, thereby allowing the roller 222 to roll uphill along the guide surface 332 and lift the cleaning mechanism 2 through the lifting rod 221. When it is necessary to control the cleaning mechanism 2 to descend, the drive assembly 32 can provide a force to the movable seat 33 to return to its original position in the direction of the second side S2. During the process of the movable seat 33 moving relative to the cleaning mechanism 2 in the direction of the second side S2, the roller 222 can roll downhill along the guide surface 332 under the gravity of the cleaning mechanism 2 and the lifting assembly 22.

[0082] The lifting cleaning mechanism 2 allows the cleaning equipment to adapt to different work surface materials (such as hard floors, carpets, etc.), preventing scratches and enabling it to overcome obstacles at low heights. Furthermore, in environments with a lot of long fibers or hair, the lifting roller brush reduces the likelihood of hair getting tangled on the cleaning mechanism 2, lowering maintenance frequency. The motion mechanism 3 of this disclosure can simultaneously drive the cleaning mechanism 2 to swing laterally and lift it. By controlling the forward and reverse rotation of the drive component 32, various positional states of the cleaning mechanism 2 can be flexibly controlled. This disclosure enhances the integration of the motion mechanism 3, eliminating the need for separate drive and transmission components for the swinging and lifting of the cleaning mechanism 2, thereby saving drive costs and internal space of the machine body 1.

[0083] According to a second aspect of this disclosure, a cleaning device is provided, comprising: a body 1, a cleaning mechanism 2, and a motion mechanism 3. The cleaning mechanism 2 is configured to clean a work surface, wherein a rolling part 21 is provided on the cleaning mechanism 2. The motion mechanism 3 is disposed on the body 1, and the cleaning mechanism 2 is configured to be floatingly connected to the motion mechanism 3 via an elastic component 31. The motion mechanism 3 is configured to drive the cleaning mechanism 2 to move relative to the body 1 between a first position and a second position; wherein, when in the second position, the cleaning mechanism 2 is configured to extend outward relative to the body 1 so that the rolling part 21 rolls in cooperation with an obstacle; during the movement of the cleaning device, the cleaning mechanism 2, under the action of an external force, has a tendency to move in the direction of the first position.

[0084] This disclosure uses an elastic component 31 to float the cleaning mechanism 2 and the motion mechanism 3, allowing the cleaning mechanism 2 to maintain a second position extending outward relative to the body 1 during edge cleaning. This extends into cleaning dead corners, increasing the cleaning coverage and achieving comprehensive cleaning. Furthermore, when the cleaning mechanism 2 collides with an obstacle, such as a wall, it can adaptively retract inward, preventing it from getting stuck and thus stopping the cleaning device, and avoiding a reduced lifespan due to a hard collision. Additionally, thanks to the elastic component 31, the cleaning mechanism 2 can extend outward again after the external force is removed, achieving complete edge cleaning. During edge cleaning, the rolling part 21 maintains contact with obstacles, such as walls, preventing the cleaning mechanism 2 from experiencing continuous resistance. The cleaning mechanism 2 will not scrape against the wall, reducing wear and tear and improving the user experience.

[0085] According to a third aspect of this disclosure, a cleaning device is provided, comprising: a body 1, a cleaning mechanism 2, and a motion mechanism 3. The cleaning mechanism 2 is configured to clean a work surface, wherein a rolling part 21 is provided on the cleaning mechanism 2. The motion mechanism 3 is disposed on the body 1, and the cleaning mechanism 2 is configured to be floatingly connected to the motion mechanism 3. The motion mechanism 3 is configured to drive the cleaning mechanism 2 to move relative to the body 1 between a first position and a second position; wherein, when in the second position, the cleaning mechanism 2 is configured to extend outward relative to the body 1 so that the rolling part 21 rolls in cooperation with an obstacle.

[0086] The cleaning mechanism 2 disclosed herein can remain in a second position extending outward relative to the body 1 during edge cleaning, thereby reaching into cleaning dead corners, increasing the cleaning coverage area, and achieving comprehensive cleaning. During the cleaning device's movement along the edge, the rolling part 21 can maintain contact with obstacles such as walls, thereby avoiding the problem of continuous resistance to the cleaning mechanism 2. The cleaning mechanism 2 will not scrape against the wall, reducing wear and tear on the cleaning mechanism 2 and improving the user experience.

[0087] Application scenarios

[0088] In home cleaning scenarios, the cleaning device is a robot vacuum and mop combo. This robot can perform cleaning tasks in open areas of the living room, as well as along walls and furniture edges. When cleaning in open areas, the cleaning mechanism 2 can remain in the first position, at which point the motion mechanism 3 does not need to be activated, thus saving drive energy. When cleaning along edges, the motion mechanism 3 can move the cleaning mechanism 2 to the second position, thereby reaching into the cleaning dead corners between the body 1 and the edge, expanding the cleaning range, leaving no dead corners, and achieving thorough cleaning.

[0089] A rolling part 21 is provided on the cleaning mechanism 2, and the rolling part 21 is constructed to protrude from the edge of the cleaning mechanism 2 on the side facing the second position direction. Therefore, when the cleaning device cleans along the edge, the side of the cleaning mechanism 2 will not directly contact the wall surface, but will achieve rolling cooperation with the wall surface through the rolling part 21, thereby reducing the frictional resistance between the robot vacuum and the obstacle wall. This disclosure, by providing the rolling part 21, avoids the problem of continuous resistance to the cleaning mechanism 2, prevents the cleaning mechanism 2 from scraping against the wall surface, reduces wear and tear on the cleaning mechanism 2, and improves the user experience.

[0090] When in the second position, the cleaning mechanism 2 is configured to extend outward relative to the body 1 so that the rolling part 21 rolls and engages with the obstacle. During the movement of the sweeping and mopping robot, the cleaning mechanism 2 tends to move in the direction of the first position under the action of external force, and when the external force is removed, the cleaning mechanism 2 tends to move in the second position under the action of the elastic component 31, so that the rolling part 21 rolls and engages with the obstacle again.

[0091] This disclosure uses an elastic component 31 to floatally connect the cleaning mechanism 2 and the motion mechanism 3. When the cleaning mechanism 2 collides with an obstacle, such as a wall, the cleaning mechanism 2 can adaptively retract inward, thereby preventing the cleaning mechanism 2 from being stuck by the obstacle. After the external force is removed, the cleaning mechanism 2 can extend outward again under the elastic force of the elastic component 31, so that the rolling part 21 rolls and engages with the obstacle, thereby achieving complete edge cleaning. The elastic component 31 can accurately adjust the relative position of the cleaning mechanism 2 and the body 1 according to the magnitude of the external force of the obstacle. During edge cleaning, the rolling part 21 can maintain rolling engagement with the obstacle, thereby ensuring complete edge cleaning.
