Description

[0001] This application claims priority to Chinese Patent Application No. 2024229809193, filed on December 3, 2024, entitled "Cleaning Equipment", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of cleaning equipment technology, and more specifically, to a cleaning device. Background Technology

[0003] Nowadays, cleaning devices such as robotic vacuum cleaners have greatly reduced people's cleaning burden by helping them with household chores. To enable robotic vacuum cleaners to meet the cleaning requirements of various complex environments, the main unit of a robotic vacuum cleaner is usually equipped with an extendable side sweeper or mop to clean hard-to-reach corners and edges. However, in existing robotic vacuum cleaners, when the main unit passes over low obstacles such as carpets or door thresholds, the mop is easily pulled outwards, preventing the main unit from completing its cleaning work properly. Utility Model Content

[0004] The main purpose of this application is to provide a cleaning device that at least solves the problem that the extended mop of a sweeping machine is easily pulled out accidentally.

[0005] According to one aspect of this application, a cleaning apparatus is provided, comprising:

[0006] Host;

[0007] A first cleaning mechanism is rotatably disposed on the host unit, and the first cleaning mechanism includes a first cleaning component, the first cleaning component is rotatably disposed on the first cleaning mechanism, and the first cleaning component can rotate along a first direction or a second direction opposite to the first direction. The first cleaning component has an inward position disposed close to the host unit and an outward position extending beyond the outer edge of the host unit. In the projection of the host unit in the height direction, the area of ​​the first cleaning component extending beyond the outer edge of the host unit when it is in the outward position is greater than the area of ​​the first cleaning component extending beyond the outer edge of the host unit when it is in the inward position.

[0008] The limiting component has a first state that avoids the first cleaning component to allow the first cleaning component to switch between the retracted position and the outward position, and the limiting component also has a second state that stops the first cleaning component to prevent the first cleaning component from being pulled by an external force to switch from the retracted position to the outward position.

[0009] Furthermore, the host is provided with a clearance notch that extends from the inside of the host to the edge of the host, and an opening is provided at one end of the clearance notch near the edge of the host. The first cleaning mechanism moves along the clearance notch to move between the outward expansion position and the inward contraction position. The opening is at least used to avoid the first cleaning mechanism so that when the first cleaning component is in the outward expansion position, the rotation center of the first cleaning component is located outside the host.

[0010] The limiting component is disposed at the edge of the clearance notch, and the limiting component switches between the first state and the second state by at least one of rotation, movement and swing. When the first cleaning component is in the retracted position and rotates along the first direction, the first cleaning component moves the limiting component to switch the limiting component to the first state. When the first cleaning component is in the retracted position and rotates along the second direction, the limiting component automatically switches to the second state. When the first cleaning component is in the expanded position and switches to the retracted position, the first cleaning component moves the limiting component to switch the limiting component to the first state.

[0011] Furthermore, the limiting component is rotatably mounted on the main unit, and the main unit is provided with a fixed spindle, the fixed spindle being located on the outer periphery of the clearance notch; the limiting component includes:

[0012] A limiting member is sleeved on the fixed spindle and can rotate around the limiting member to switch between the first state and the second state;

[0013] An elastic reset member, the two ends of which abut against the host and the limiting member respectively, the elastic reset member being configured to cause the limiting member to automatically return to the second state.

[0014] Furthermore, the elastic reset member includes a torsion spring, which is sleeved on the fixed spindle, with one end of the torsion spring abutting against the limiting member and the other end of the torsion spring abutting against the main unit.

[0015] Furthermore, the main unit includes a bottom shell, the clearance notch and the fixed spindle are both disposed on the bottom shell, and a first limiting part is provided on the side of the fixed spindle near the opening of the clearance notch. The first limiting part is at least used to limit the extreme position of the limiting member when it rotates toward the opening side of the clearance notch.

[0016] Furthermore, a limiting opening is provided at the edge of the avoidance notch, and a second limiting part is provided on the bottom shell;

[0017] The first limiting part is located at one end of the limiting port near the opening of the clearance notch, and the second limiting part is located at one end of the limiting port away from the opening of the clearance notch. The second limiting part is at least used to limit the extreme position of the limiting member when it rotates toward the side away from the opening of the clearance notch. The fixed spindle is located on the side of the limiting port away from the first cleaning mechanism. The limiting member is inserted into the limiting port and can swing within the limiting port, and the swing angle of the limiting member within the limiting port is less than or equal to 60°.

[0018] Furthermore, the first cleaning mechanism also includes a first power component, which includes a first drive element and a first transmission assembly;

[0019] The first transmission assembly is rotatably mounted on the host. The housing of the first drive member is fixedly connected to the housing of the first transmission assembly. The first transmission assembly is connected between the first drive member and the first cleaning component. The first drive member drives the first transmission assembly to drive the first cleaning component to rotate along the first direction or the second direction. The first transmission assembly is provided with a meshing port. The meshing port is at least used to mesh with the limiting component when the first cleaning component rotates along the first direction, and to move the limiting component from the second state to the first state.

[0020] Furthermore, the width of the limiting component is d1, and the width of the engagement opening is d2. d1 and d2 satisfy the relationship: d1 < d2.

[0021] When the limiting component engages with the engagement port, there is a gap between the limiting component and the engagement port, the width of the gap being D, and the depth of the engagement port being G. D and G satisfy the following relationship:

[0022] Furthermore, the first transmission assembly includes a first transmission member and a second transmission member. The first driving member is driven to the first transmission member to drive the first transmission member to rotate along the first direction or the second direction. The first transmission member abuts against the second transmission member. The second transmission member rotates along the first direction or the second direction under the drive of the first transmission member and rises or falls along the height direction of the host. The engagement port is provided on the outer surface of the second transmission member.

[0023] When the first cleaning component is in the retracted position, the limiting component and the second transmission component are misaligned within the projection of the host in the height direction;

[0024] When the first cleaning component switches between the retracted position and the expanded position, the second transmission component contacts the limiting component and moves the limiting component through the engagement port to switch the limiting component from the second state to the first state.

[0025] Furthermore, the second transmission member includes an annular protrusion that extends along the outer peripheral surface of the second transmission member, and the engagement port is disposed on the annular protrusion and recessed along the radial direction of the annular protrusion.

[0026] Furthermore, the second transmission component also includes a baffle rib, which is disposed on the outer surface of the second transmission component and extends along the height direction of the second transmission component. The engagement port is disposed at the first position of the annular protrusion, and the position where the baffle rib and the annular protrusion intersect is the second position. The first position and the second position are misaligned.

[0027] Furthermore, the second transmission member, under the support of the first transmission member, has the ability to rise to the highest first limit position along the height direction of the host, or to descend to the lowest second limit position along the height direction of the host.

[0028] Along the height direction of the host, the height of the limiting component is greater than the thickness of the annular protrusion, and the height of the limiting component is greater than or equal to the maximum stroke of the second transmission component in the height direction. When the first cleaning component is in the first extreme position, the top of the limiting component is higher than or equal to the top of the annular protrusion. When the first cleaning component is in the second extreme position, the bottom of the limiting component is lower than or equal to the bottom of the annular protrusion.

[0029] Furthermore, the first cleaning mechanism also includes a first stop component, which is disposed in the first cleaning mechanism and has a clearance opening. The clearance opening is at least used to avoid the limiting component to prevent interference between the first stop component and the first stop component.

[0030] When the first cleaning component protrudes from the edge of the host to clean and comes into contact with an obstacle, the first stop component is driven by the force exerted by the obstacle to swing the first cleaning mechanism, thereby moving the first cleaning component toward the inward position.

[0031] In the actual operation of the cleaning device of this application, when the cleaning device is not performing edge cleaning, the first cleaning component rotates in the second direction. During this process, due to the friction between the surface to be cleaned (which may be the ground, tabletop, etc.) and the first cleaning component, and since the direction of the friction force on the first cleaning component is tangential to the first direction, the first cleaning component can swing in the first direction to maintain an inward position for cleaning the surface to be cleaned. Simultaneously, during the swinging of the first cleaning component in the first direction, the limiting component can maintain a second state to further prevent the first cleaning component from protruding beyond the outer edge of the main unit. When the cleaning device performs edge cleaning, the first cleaning component rotates in the first direction. During this process, due to the friction between the surface to be cleaned and the first cleaning component, and since the direction of the friction force on the first cleaning component is tangential to the second direction, the first cleaning component can swing in the second direction to change from an inward position to an outward position, thereby cleaning the edges of obstacles such as walls and furniture. Simultaneously, during the swinging of the first cleaning mechanism in the second direction (i.e., the first cleaning component moves from the retracted position to the outward position), the limiting component can switch from the second state to the first state, thereby avoiding the first cleaning component and allowing it to protrude beyond the outer edge of the main unit. Furthermore, when the first cleaning component rotates in the second direction or stops rotating, if an external force pulls the first cleaning component from the retracted position to the outward position, the limiting component can maintain the second state to stop the first cleaning component, thus preventing it from being accidentally pulled outside the main unit.

[0032] In other words, this application provides a limiting component with two states (i.e., the first state and the second state) on the host, which has the functions of avoiding and stopping the first cleaning component. By controlling the first cleaning component to rotate in different directions (i.e., the first direction or the second direction) according to different cleaning needs, the first cleaning component can be prevented from being accidentally pulled out of the host, thereby improving the reliability and stability of the cleaning device.

[0061] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0064] As described in the background section, cleaning devices such as robotic vacuum cleaners can significantly reduce people's cleaning burden. While the extended side sweeper or mop design allows robotic vacuum cleaners to meet the cleaning requirements of many complex environments, the mop can easily be accidentally pulled out to the extended area when the main unit passes low obstacles such as carpets or thresholds, preventing the main unit from completing its cleaning work properly. Therefore, there is an urgent need for a cleaning device that can prevent the mop from being accidentally pulled out, so that the cleaning device can meet the cleaning requirements of even more complex environments.

[0065] See Figures 1 to 25 As shown, this application embodiment provides a cleaning device 100, which includes, but is not limited to, a sweeping robot (including one or more cleaning mechanisms), a floor scrubber (a robot with mopping function but no sweeping function), a sweeping and mopping robot, a floor scrubbing robot (such as a handheld floor scrubbing robot or a non-handheld floor scrubbing robot), or a base station having the above-mentioned sweeping robot, floor scrubber, sweeping and mopping robot, or floor scrubbing robot. The cleaning device 100 includes a main unit 10, a first cleaning mechanism 20, and a limiting component 60.

[0066] The first cleaning mechanism 20 is rotatably mounted on the main unit 10, and includes a first cleaning component 22. The first cleaning component 22 is rotatably mounted on the first cleaning mechanism 20, and can rotate in a first direction or a second direction opposite to the first direction. The first cleaning component 22 has an inwardly recessed position close to the main unit 10 (e.g., ...). Figure 1 , Figure 2 , Figure 6 as well as Figure 7 (as shown) and the extended positions beyond the outer edge of the host 10 (such as...) Figure 3 , Figure 8As shown in the figure, within the projection along the height direction of the host 10, the area of ​​the first cleaning component 22 extending beyond the outer edge of the host 10 when it is in the outward position is greater than the area of ​​the first cleaning component 22 extending beyond the outer edge of the host 10 when it is in the inward position. It is understood that when the first cleaning component 22 is in the inward position, it may partially extend beyond the outer edge of the host 10, or it may be entirely within the host 10 and not protrude beyond its outer edge at all; when the first cleaning component 22 is in the outward position, the area of ​​the first cleaning component 22 protruding beyond the outer edge of the host 10 is greater than the area of ​​the first cleaning component 22 protruding beyond its outer edge when it is in the inward position. In some embodiments of this application, when the first cleaning component 22 is in the outward position, it is preferable that the first cleaning component 22 protrudes beyond the outermost edge of the host 10 in a predetermined direction (perpendicular to the direction of movement of the host 10). This makes it more suitable for the host 10 to move and drive the first cleaning component 22 to clean the edges of obstacles such as walls and furniture. The limiting member 60 has a first state that avoids the first cleaning member 22 to allow the first cleaning member 22 to switch between an inward position and an outward position. The limiting member 60 also has a second state that stops the first cleaning member 22 to prevent the first cleaning member 22 from being pulled by an external force to switch from an inward position to an outward position.

[0067] In the actual operation of the cleaning device 100 of this application, when the cleaning device 100 is not performing edge cleaning, the first cleaning component 22 rotates in the second direction. During this process, due to the friction between the surface to be cleaned (which may be the ground, tabletop, etc.) and the first cleaning component 22, and since the direction of the friction force on the first cleaning component 22 is tangential to the first direction, the first cleaning component 22 can swing in the first direction to maintain an inward position for cleaning the surface to be cleaned. Simultaneously, during the swinging of the first cleaning component 22 in the first direction, the limiting component 60 can maintain a second state to further prevent the first cleaning component 22 from protruding beyond the outer edge of the main unit 10. When the cleaning device 100 performs edge cleaning, the first cleaning component 22 rotates in the first direction. During this process, due to the friction between the surface to be cleaned and the first cleaning component 22, and since the direction of the friction force on the first cleaning component 22 is tangential to the second direction, the first cleaning component 22 can swing in the second direction to change from an inward position to an outward position, thereby cleaning the edges of obstacles such as walls and furniture. Simultaneously, during the swinging of the first cleaning mechanism 20 in the second direction (i.e., the first cleaning component 22 moves from the retracted position to the outward expansion position), the limiting component 60 can switch from the second state to the first state, thereby avoiding the first cleaning component 22 so that the first cleaning component 22 can protrude beyond the outer edge of the main unit 10. Furthermore, when the first cleaning component 22 rotates in the second direction or stops rotating, if an external force pulls the first cleaning component 22 from the retracted position to the outward expansion position, the limiting component 60 can maintain the second state to stop the first cleaning component 22, thereby preventing the first cleaning component 22 from being accidentally pulled out of the main unit 10.

[0068] For example, the retracted position includes multiple retracted position points. When the first cleaning component 22 retracts to the innermost position of the host 10, the first cleaning component 22 is at the extreme position of the retracted position. The outward expansion position includes multiple outward expansion position points. When the first cleaning component 22 expands to the outermost position of the host 10, the first cleaning component 22 is at the extreme position of the outward expansion position. Positions within a first predetermined distance range from the extreme position of the retracted position to the extreme position of the outward expansion position are all considered retracted positions. Positions within a second predetermined distance range from the extreme position of the outward expansion position to the extreme position of the retracted position are all considered outward expansion positions. The specific sizes of the first and second predetermined distances can be adjusted according to needs and actual circumstances. This application does not limit the specific sizes of the first and second predetermined distances. Any implementation that adjusts the first and second predetermined distances under the concept of this application is within the scope of protection claimed in this application. See also Figure 11As shown, R1 is a first tangent line R1 that is tangent to the edge of the host 10 along a predetermined direction. When the first cleaning component 22 moves along the direction from N1 to N2, if the first cleaning component 22 is in a position that does not exceed the first tangent line R1 (i.e., the first cleaning component 22 is in a position that does not exceed the first tangent line R1), Figure 11 If the mop holder 221 is positioned as shown by the solid line in the middle, then the first cleaning component 22 is in the retracted position; if the first cleaning component 22 is positioned beyond the first tangent R1 (i.e., the first cleaning component 22 is positioned beyond the first tangent R1), then the first cleaning component 22 is in the retracted position; Figure 11 The position of the mop bracket 221 is shown by the solid line in the middle, for example... Figure 11 (The position of the mop bracket 221 is shown by the dashed line in the middle), then the first cleaning component 22 is in the outward expansion position.

[0069] In other words, by setting a limiting component 60 with two states (i.e., the first state and the second state) on the host 10, which has the functions of avoiding and stopping the first cleaning component 22 respectively, and by controlling the first cleaning component 22 to rotate in different directions (i.e., the first direction or the second direction) according to different cleaning needs, the first cleaning component 22 can be prevented from being accidentally pulled out of the host 10, thereby improving the reliability and stability of the cleaning device 100.

[0070] When the cleaning device 100 of this application is in operation, the cleaning device 100 is configured such that when the first cleaning component 22 rotates in the first direction and is subjected to a torque in the second direction, the first cleaning mechanism 20 swings relative to the main unit 10 in the second direction, thereby causing the first cleaning component 22 to be in an outwardly expanded position. Specifically, when the first power component 21 drives the first cleaning component 22 to rotate in the first direction, when the first cleaning component 22 contacts the surface to be cleaned, such as the ground or countertop, a torque is generated. This torque causes the entire first cleaning mechanism 20 to swing relative to the main unit 10 in the second direction, opposite to the first direction, thereby causing the first cleaning component 22 to protrude beyond the outer edge of the main unit 10 and be in an outwardly expanded position. At this time, the first cleaning component 22 can avoid interference between the main unit 10 and obstacles such as furniture or walls, and can contact the edge of the wall or furniture to perform edge cleaning.

[0071] The cleaning device is also configured such that when the first cleaning component 22 rotates in the second direction and is subjected to a torque in the first direction, the first cleaning mechanism 20 swings relative to the main unit 10 in the first direction, thereby causing the first cleaning component 22 to be in an inward position. Specifically, when the first power component 21 drives the first cleaning component 22 to rotate in the second direction, a torque is generated when the first cleaning component 22 contacts the surface to be cleaned, such as the ground or countertop. This torque causes the entire first cleaning mechanism 20 to swing relative to the main unit 10 in the first direction, which is opposite to the second direction, thereby causing the first cleaning component 22 to retract to the inside of the main unit 10 and be in an inward position. At this time, it is convenient to extend and retract the cleaning device 100.

[0072] It is understood that the first direction in this application can be clockwise or counterclockwise. When the first direction is clockwise, the second direction is counterclockwise; when the first direction is counterclockwise, the second direction is clockwise. Figure 7 and Figure 18 As shown, in this embodiment, the first direction is clockwise (i.e., Figure 18 The direction indicated by 'e' is the first direction, and the second direction is counterclockwise (i.e., the direction indicated by 'e'). Figure 18 (The direction indicated by f in the middle). In this application, the specific directions referred to by the first direction and the second direction can vary depending on the viewing angle and the installation position of the first cleaning mechanism 20 on the bottom shell 14. Figure 7 From the presented perspective, if the first cleaning mechanism 20 is positioned where the second cleaning mechanism 30 is located, then the first direction is counterclockwise and the second direction is clockwise. This application mainly describes the case where the first direction is clockwise and the second direction is counterclockwise. Furthermore, the torque in this application can be the frictional torque exerted by the ground or countertop on the first cleaning component 22 when it rubs against the ground or countertop; it can also be the torque generated by the reaction force of other objects on the first cleaning component 22 when the centrifugal force of the first cleaning component 22's rotation acts on other objects; or it can be the torque exerted by other friction mechanisms on the first cleaning component 22 when the first cleaning component 22 comes into contact with other friction mechanisms.

[0073] Further, see Figures 17 to 21 , Figure 25As shown, the main unit 10 is provided with a clearance notch 141, which extends from the inside of the main unit 10 towards its edge. An opening 1411 is provided at one end of the clearance notch 141 near the edge of the main unit 10. The first cleaning mechanism 20 moves along the clearance notch 141 to move between an outwardly expanding position and an inwardly contracted position. The opening is at least used to allow the first cleaning mechanism 20 to move so that when the first cleaning component 22 is in the outwardly expanding position, the rotation center of the first cleaning component 22 is located outside the main unit 10. A limiting component 60 is rotatably disposed at the edge of the clearance notch 141, and the limiting component 60 switches between a first state and a second state by at least one of rotation, movement, and oscillation. When the first cleaning component 22 is in the inwardly contracted position and rotates in a first direction, the first cleaning component 22 pushes the limiting component 60 to rotate, causing the limiting component 60 to switch to the first state. When the first cleaning component 22 is in the inwardly contracted position and rotates in a second direction, the limiting component 60 automatically switches to the second state. When the first cleaning component 22 is in the outward expansion position and is switching to the inward retraction position, the first cleaning component 22 moves the limiting component 60 to switch the limiting component 60 to the first state.

[0074] Specifically, the clearance notch 141 on the main unit 10 allows the first cleaning mechanism 20 to swing flexibly inside the main unit 10 without interfering with other internal components. The clearance notch 141 also allows the first cleaning component 22 to pass through and connect to the first power component 21, thereby driving the first cleaning component 22 to rotate in a first or second direction and switch between an outward and inward position. When actually designing the clearance notch 141, it is necessary to consider not only the internal space of the main unit 10 but also the swing trajectory of the first cleaning mechanism 20, ensuring that the first cleaning component 22 can move along the clearance notch 141 without excessively affecting the structural strength of the main unit 10. The design allowing the first cleaning component 22 to switch between outward and inward positions expands the cleaning range of the cleaning device 100 and improves cleaning efficiency. The opening 1411 allows the rotation center of the first cleaning component 22 to protrude beyond the outer edge of the main unit 10 when the first cleaning component 22 is in the outward expansion position. This allows the first cleaning component 22 to expand further relative to the main unit 10, thereby increasing the cleaning range of the cleaning device 100. When the first cleaning component 22 rotates in the first direction, the limiting component 60 can be switched to the first state to avoid the swing path of the first cleaning component 22, ensuring that the first cleaning component 22 can switch between the outward expansion position and the inward retraction position. When the first cleaning component 22 rotates in the second direction, the limiting component 60 can automatically switch to the second state to stop the first cleaning component 22 in the swing path of the first cleaning component 22, thereby preventing the first cleaning component 22 from being accidentally pulled out to the outward expansion position from the inward retraction position. This not only prevents the first cleaning component 22 from being accidentally damaged, but also ensures that the cleaning operation of the cleaning device 100 can be carried out normally. In this application, the limiting component 60 switches between a first state and a second state through at least one of rotation, movement, and swinging. When actually setting the limiting component 60, the movement mode of the limiting component 60 can be reasonably selected according to the actual situation and the different structures of the cleaning device 100. This embodiment shows the situation where the limiting component 60 switches between the first state and the second state through swinging movement. This application mainly describes the situation where the limiting component 60 switches between the first state and the second state through swinging movement. That is to say, the cleaning device 100 of this application can limit the first cleaning mechanism 20 by switching the limiting component 60 between different states (first state and second state), preventing the first cleaning mechanism 20 from being pulled out unexpectedly (the first cleaning component 22 being forcibly pulled towards the outer edge of the host 10 under the action of external force), thereby preventing the first cleaning component 22 from being forcibly pulled out of the host 10, ensuring the reliability and safety of the cleaning device 100 during operation.

[0075] Further, see Figure 17 , Figure 18 , Figures 22 to 25 As shown, the limiting component 60 is rotatably mounted on the main unit 10, and the main unit 10 is provided with a fixed spindle 142, which is located on the outer periphery of the clearance notch 141. The limiting component 60 includes a limiting member 61 and an elastic reset member 62. The limiting member 61 is sleeved on the fixed spindle 142 and can rotate around the limiting member 61 to switch between a first state and a second state. The two ends of the elastic reset member 62 abut against the main unit 10 and the limiting member 61, respectively, and the elastic reset member 62 is configured to automatically restore the limiting member 61 to the second state.

[0076] Specifically, the fixed spindle 142 is fixedly connected to the main unit 10, and does not swing with the limiting component 60 during actual operation. The fixed spindle 142 provides a clear rotation center for the limiting component 60, ensuring that the limiting component 61 maintains precise positioning during rotation, thereby guaranteeing accurate transitions and stability of the first cleaning mechanism 20 between different states (first state and second state). The elastic reset component 62 not only provides elastic support for the rotation of the limiting component 61, but also ensures that the limiting component 61 automatically returns to the second state when no external force is applied. This automatic reset design improves the reliability and automation of the cleaning device 100, reducing the need for manual operation to some extent. Furthermore, the elastic reset component 62 provides a certain buffering effect during the rotation of the limiting component 61, reducing wear on the limiting component 61 or the main unit 10 caused by mechanical impact, and helping to extend the service life of the cleaning device 100. The combined use of the limiting component 61 and the elastic reset component 62 effectively prevents the first cleaning mechanism 20 from being accidentally pulled out to the outer edge of the main unit 10 under external force, avoiding malfunctions or damage caused by improper operation or environmental influences. Furthermore, the design of the fixed spindle 142 and the limiting component 60 makes the entire structure relatively simple and modular, facilitating disassembly and maintenance, and reducing the maintenance cost and time of the cleaning device 100. Moreover, due to the presence of the elastic reset component 62, the user does not need to manually intervene in the reset process of the limiting component 60, making operation more convenient and improving the user experience.

[0077] Further, see Figures 22 to 25 As shown, the elastic reset member 62 includes a torsion spring 621, which is sleeved on the fixed spindle 142. One end of the torsion spring 621 abuts against the limiting member 61, and the other end of the torsion spring 621 abuts against the main unit 10.

[0078] Specifically, the torsion spring 621 provides a stable torque, ensuring precise elastic support for the limiting member 61 during rotation, thereby guaranteeing the accuracy and stability of the limiting member 61's transition between different states (first state and second state). The design of the torsion spring 621 being sleeved on the fixed spindle 142 and the limiting member 61 being sleeved on the outer periphery of the torsion spring 621 fully utilizes the limited internal space of the main unit 10, while also making the overall structure of the limiting member 60 more compact, contributing to a reduction in the overall size of the cleaning device 100. The elastic force of the torsion spring 621 allows the limiting member 61 to quickly and reliably return to the second state without human intervention, ensuring operational continuity and the degree of automation of the cleaning device 100.

[0079] Further, see Figures 17 to 20 , Figure 25 As shown, the main unit 10 includes a bottom shell 14, an clearance notch 141 and a fixed spindle 142 are both disposed on the bottom shell 14. A first limiting part 143 is provided on the side of the fixed spindle 142 near the opening 1411 of the clearance notch 141. The first limiting part 143 is at least used to limit the extreme position of the limiting member 61 when it rotates toward the opening 1411 side of the clearance notch 141.

[0080] Specifically, the first limiting part 143 effectively prevents the limiting member 61 from rotating towards the outer edge of the host 10 when it is in the second state. This prevents the limiting member 61 from exceeding the predetermined limit position (i.e., the position of the limiting member 61 in the second state) during rotation, avoiding mechanical damage or functional failure that may be caused by excessive rotation, and improving the safety and reliability of the cleaning device 100. In this embodiment, when the limiting member 61 is in the second state, it is always in contact with the first limiting part 143 under the action of the elastic reset member 62. This ensures that when the first cleaning mechanism 20 rotates in the first direction, the limiting member 61 can stop the first cleaning mechanism 20 and prevent it from being accidentally pulled out to the outer edge of the host 10. In other embodiments of this application, a limiting member 61 may also be provided on the side of the fixed spindle 142 away from the opening of the avoidance notch 141, so as to ensure that the limiting member 61 does not rotate excessively when transitioning from the second state to the first state, thereby avoiding the embarrassing situation that the limiting member 61 cannot automatically return to the second state due to excessive rotation.

[0081] Further, see Figure 25As shown, a limiting opening 144 is provided at the edge of the clearance notch 141, and a second limiting part 145 is provided on the bottom shell 14. The first limiting part 143 is located at one end of the limiting opening 144 near the opening 1411 of the clearance notch 141, and the second limiting part 145 is located at one end of the limiting opening 144 away from the opening 1411 of the clearance notch 141. The second limiting part 145 is at least used to limit the extreme position of the limiting member 61 when it rotates toward the side away from the opening 1411 of the clearance notch 141. The fixed spindle 142 is located on the side of the limiting opening 144 away from the first cleaning mechanism 20. The limiting member 61 is inserted into the limiting opening 144 and can swing within the limiting opening 144, and the swing angle of the limiting member 61 within the limiting opening 144 is less than or equal to 60°.

[0082] Specifically, the first limiting part 143 is located at the end of the limiting opening 144 near the opening 1411 of the clearance notch 141, restricting the movement of the limiting member 61 in the direction of the clearance notch opening and preventing the limiting member 61 from swinging excessively or dislodging. In this embodiment, the first limiting part 143 restricts the position of the limiting member 61 at the first limiting part 143, preventing the limiting member 61 from continuing to rotate in the first direction (clockwise in this embodiment). The second limiting part 145 is located at the end of the limiting opening 144 away from the opening 1411, restricting the limiting member 61 to its rotational limit position away from the opening direction. In this embodiment, the second limiting part 145 restricts the position of the limiting member 61 at the second limiting part 145, preventing the limiting member 61 from continuing to rotate in the second direction (counterclockwise in this embodiment). This design ensures that the limiting member 61 will not exceed the predetermined range during swinging, allowing it to swing only between the first limiting part 143 and the second limiting part 145 (i.e., within the limiting opening 144), thus preventing interference or damage to other components. The fixed spindle 142 serves as a support point, enabling the limiting member 61 to rotate around it. This, combined with the structure of the limiting opening 144, ensures accurate movement of the limiting member 61. In this embodiment, the specific positions of the fixed spindle 142, the first limiting part 143, the limiting opening 144, and the second limiting part 145 should satisfy the requirement that the swing angle of the limiting member 61 within the limiting opening 144 is less than or equal to 60°. This allows the limiting member 61 to better avoid or stop the first cleaning component 22, while also ensuring precise control over its movement range. Through the coordinated action of the first limiting part 143, the second limiting part 145, and the fixed spindle 142, the movement of the limiting member 61 is strictly limited within a predetermined range, reducing the risk of failure due to excessive or unstable movement and improving the overall structural stability. Furthermore, the design of the limiting port 144 and the limiting parts (i.e., the first limiting part 143 and the second limiting part 145) makes the installation and disassembly of the limiting member 61 more convenient, facilitating maintenance and replacement. At the same time, the clearly defined limiting structure also helps ensure the correct position of each component during assembly, improving assembly efficiency.

[0083] Furthermore, a first stop component 23 is disposed on the first power component 21. This first stop component 23 is configured to contact the obstacle when the first cleaning component 22 is in the outwardly extended position, thereby preventing the first cleaning component 22 from making hard contact with the obstacle. It is understood that preventing the first cleaning component 22 from making hard contact with the obstacle means that there is no hard object in the first cleaning component 22 or other structures with hard supports inside that directly contact the obstacle.

[0084] The first stop component 23, under the reaction force exerted by the obstacle, causes the first cleaning mechanism 20 to swing (specifically, swing relative to the main unit 10), thereby moving the first cleaning component 22 toward a position closer to the inward retraction. It is understood that the obstacles described in this application include, but are not limited to, indoor walls, coffee tables, chairs, beds, refrigerators, and other furniture, as well as other objects placed in the space.

[0085] This application incorporates a first stop component 23. When the first cleaning component 22 extends outward to its outermost edge protruding from the main unit 10 in a predetermined direction to clean the edges of obstacles such as walls and furniture, if the first cleaning component 22 is close to the obstacle, the first stop component 23 contacts the obstacle to prevent hard contact, thus preventing the rotating first cleaning component 22 from scratching the obstacle. Simultaneously, the first stop component 23, subjected to the reaction force exerted by the obstacle, causes the entire first cleaning mechanism 20 to swing, moving the first cleaning component 22 towards an inward position. Afterward, when the force exerted by the obstacle on the first stop component 23 disappears, the first power component 21 continuously drives the first cleaning component 22 to rotate in the first direction. The frictional torque generated by the first cleaning component 22 contacting the ground can switch the first cleaning component 22 to the outward position to clean the edges of obstacles.

[0086] It is evident that the cleaning device 100 in this application not only facilitates cleaning the edges of obstacles, but also prevents scratching of obstacles.

[0087] See Figure 15 and Figure 16 As shown, the first cleaning component 22 rotates clockwise, where f is the frictional force between the first cleaning component 22 and the ground, F1 is the contact force generated when the obstacle comes into contact with the first cleaning component 22 or the first stop component 23, and F2 is the frictional force exerted by the obstacle on the first stop component 23 or the first cleaning component 22. The torques exerted by the above forces on the first cleaning mechanism 20 are M, respectively. f =f*L3,M F1 =F1*L2, M F2 =F1*L1. Wherein, the net torque of the first cleaning mechanism 20 is defined as follows: if the net torque is greater than 0, the first cleaning mechanism 20 rotates counterclockwise; if the torque is less than 0, the first cleaning mechanism 20 rotates clockwise. The net torque on the first cleaning mechanism 20 is M. f +M F1 +M F2 .

[0088] exist Figure 15 In the middle, based on the force analysis, it can be determined that: M f +M F1 +M F2>0, meaning that without the first stop component 23, when the first cleaning component 22 contacts the obstacle, the resultant torque of the first cleaning mechanism 20 is positive, the first cleaning mechanism 20 rotates counterclockwise, always exhibiting an outward expansion trend, and the first cleaning mechanism 20 cannot retract upon impact. Figure 16 In the middle, based on the force analysis, it can be determined that: M f +M F1 +M F2 <0, that is to say, when the first stop component 23 is set in this embodiment, when the first cleaning component 22 comes into contact with the obstacle, the resultant torque of the first cleaning mechanism 20 is negative, the first cleaning mechanism 20 rotates in the clockwise direction, and the torque generated by the contact force between the first stop component 23 and the obstacle on the rotation center of the entire first cleaning mechanism 20 will cause the component to retract, so that the entire first cleaning mechanism 20 can achieve flexible outward expansion.

[0089] like Figures 2 to 5 , Figure 8 as well as Figure 13 As shown, within the projection of the host 10 in the height direction, the first stop member 23 at least partially protrudes from the outer edge of the first cleaning member 22 to contact the obstacle, thereby preventing the first cleaning member 22 from making hard contact with the obstacle. That is to say, in this application, by connecting the first stop member 23 to the first power member 21 and making the first stop member 23 protrude from the outer edge of the first cleaning member 22 at least partially within the projection of the host 10 in the height direction, the first cleaning member 22 can contact the obstacle when it expands to the outward position, thereby preventing the first cleaning member 22 from making hard contact with the obstacle and preventing the first cleaning member 22 from scratching the obstacle when rotating. The structure is simple and easy to implement.

[0090] In some embodiments of this application, the first cleaning component 22 includes, but is not limited to, a mop assembly, a roller assembly, and a side sweeper assembly. This application focuses on the mop assembly as the first cleaning component 22. Specifically, the first cleaning component 22 includes a mop support 221 and a flexible mop 222. The mop support 221 is connected to a first power component 21 and rotates in a first direction or a second direction under the drive of the first power component 21; the flexible mop 222 is disposed on the bottom surface of the mop support 221. The first stop component 23 includes a stop plate 231. In the projection of the main unit 10 in the height direction, the stop plate 231 at least partially protrudes from the outer edge of the mop support 221. Thus, when the first cleaning component 22 expands to its expanded position, the stop plate 231 can contact the obstacle before the rigid mop support 221 on the first cleaning component 22, preventing the rigid mop support 221 from scratching the obstacle during the cleaning operation.

[0091] Optionally, within the projection of the host 10 in the height direction, the flexible mop 222 protrudes from the outer edge of the mop support 221, and the stop plate 231 is located inside the flexible mop 222. With this configuration, when the stop plate 231 contacts an obstacle, the flexible mop 222 can also contact the obstacle. At this time, if the mop support 221 drives the flexible mop 222 to rotate, the flexible mop 222 can effectively clean the edges of the obstacle. Therefore, during the cleaning operation, the cleaning device 100 of this application can not only clean the edges of obstacles but also avoid scratching them.

[0092] For ease of processing and assembly, the stop plate 231 in this application can be disposed on the first transmission component 212 of the first power component 21 by means of snap-fit, screw-fit, welding, magnetic attraction, integral molding, etc., specifically disposed on the outer shell or surface of the first transmission component 212, which is not specifically limited in this application. In addition, in other embodiments of this application, the first stop component 23 can also be a stop block, stop post, etc. Any other variation under the concept of this application is within the protection scope of this application.

[0093] Furthermore, such as Figure 13 As shown, within the projection along the height of the host 10, the maximum width D of the stop plate 231 protruding from the outer edge of the mop bracket 221 satisfies the relationship: 0 < D ≤ 5 mm. For example, the value of D can be 1 mm, 2 mm, 3 mm, 4 mm, or 5 mm. When the maximum width D of the stop plate 231 protruding from the outer edge of the mop bracket 221 is less than or equal to 0, the stop plate 231 cannot contact the obstacle before the mop bracket 221. When the maximum width D of the stop plate 231 protruding from the outer edge of the mop bracket 221 is greater than 5 mm, the mop bracket 221 cannot adequately support the flexible mop 222, making it difficult to effectively clean the edges of the obstacle. Therefore, by ensuring that the maximum width D of the stop plate 231 protruding from the outer edge of the mop bracket 221 satisfies the relationship 0 < D ≤ 5 mm, this application not only prevents the rigid mop bracket 221 from scratching the obstacle but also facilitates support for the flexible mop 222, enabling effective cleaning of the edges of the obstacle.

[0094] Optionally, the maximum width L of the flexible mop 222 protruding from the outer edge of the stop plate 231 in this application satisfies the relationship 0≤L≤5mm. For example, the value of L can be 0mm, 1mm, 2mm, 3mm, 4mm, or 5mm, etc. When the maximum width L of the flexible mop 222 protruding from the outer edge of the stop plate 231 is less than 0, the flexible mop 222 cannot contact the obstacle, making it inconvenient to clean the edge of the obstacle. When the maximum width of the flexible mop 222 protruding from the outer edge of the stop plate 231 is greater than 5mm, during the operation of the cleaning device 100, the flexible mop 222 is prone to snagging on objects in the space, and it is not convenient to stably install the flexible mop 222 on the mop bracket 221. When the cleaning device 100 is working, it is easy to get stuck. As can be seen, by making the maximum spacing width L of the flexible mop 222 protruding from the outer edge of the stop plate 231 satisfy the relationship 0≤L≤5mm, it is not only convenient to clean the edge of the obstacle, but also convenient to install the flexible mop 222 stably on the mop bracket 221, preventing the flexible mop 222 from getting caught on the obstacle or other objects in the space, thereby improving the operational stability and reliability of the cleaning device 100.

[0095] It should be noted that the maximum width L of the flexible mop 222 protruding from the outer edge of the stop plate 231 described in this application is the maximum width of the cleaning device 100 in its natural state. The cleaning device 100 in its natural state means that the cleaning device 100 is placed on a horizontal surface, the flexible mop 222 is in contact with the ground, and the flexible mop 222 is not subjected to pressure.

[0096] In actual assembly, the flexible mop 222 in this application is detachably mounted on the bottom of the mop bracket 221 via Velcro. This design facilitates the removal of the flexible mop 222 for cleaning or replacement. Of course, in other embodiments of this application, the flexible mop 222 can also be detachably mounted on the mop bracket 221 via fasteners such as snaps, magnets, or screws. Any other variations within the concept of this application are within the scope of protection of this application.

[0097] Combination Figures 1 to 10 As shown, the stop plate 231 in this application includes a circular plate or a sector-shaped plate. The accompanying drawings of this application show the case where the stop plate 231 is a sector-shaped plate. In this application, the stop plate 231 is set as a sector-shaped plate, which can reduce the space occupied by the stop plate 231 in the cleaning device 100 to a certain extent, making it easier to avoid other components on the cleaning device 100, thereby facilitating the lightweight and miniaturized design of the cleaning device 100, and also reducing the material cost of the cleaning device 100.

[0098] See Figures 10 to 12As shown, the mop bracket 221 in this application includes a circular bracket. Within the projection of the main unit 10 in the height direction, the stop plate 231 has an arcuate portion 23101 protruding from the circular bracket. This arcuate portion 23101 extends along the outer periphery of the circular bracket. In actual design, the minimum central angle of this arcuate portion 23101 is A, where A is the angle between the first radius line X and the second radius line Y. The first radius line X is the line connecting the center O of the circular bracket and the first tangent point B1. The first tangent point B1 is the point of tangency formed when the circular bracket expands outward to be tangent to the first tangent line R1 at the outermost edge of the main unit 10 in a predetermined direction. The first tangent line R1 is parallel to the moving direction of the main unit 10. The second radius line Y is the line connecting the center O of the circular bracket and the second tangent point B2. The second tangent point B2 is the point of tangency between the circular bracket and the second tangent line R2 when the circular bracket expands outward to its limit position. The second tangent line R2 is the point on the circular bracket furthest from the main unit 10 in the predetermined direction and is parallel to the first tangent line R1. It is understood that the extreme position described in this application refers to the position where the circular bracket extends to the position furthest from the outermost edge of the host 10 in a predetermined direction.

[0099] In this application, by setting the minimum central angle of the arc portion 23101 to A, and making A the angle between the first radius line X and the second radius line Y, the first stop component 23 can contact the obstacle before the mop bracket 221 when the cleaning device 100 moves and the first cleaning component 22 is at the outer edge of the main unit 10, thus preventing the obstacle from hitting the mop bracket 221. Furthermore, when designing the stop plate 231, it is only necessary to ensure that the stop plate 231 has an arc portion 23101 protruding from the mop bracket 221, and that the central angle corresponding to the arc portion 23101 is greater than or equal to A. This optimizes the size of the stop plate 231, thereby ensuring that the first stop component 23 contacts the obstacle before the mop bracket 221, while also rationally designing the smallest possible size for the first stop component 23, allowing it to effectively avoid other components on the cleaning device 100.

[0100] Combination Figures 1 to 5As shown, the main unit 10 is provided with a rotating part 11 and an elastic element 12. The first cleaning mechanism 20 is rotatably connected to the main unit 10 through the rotating part 11 to drive the first cleaning component 22 to switch between an outward expansion position and an inward retraction position. The elastic element 12 extends and retracts along the rotation direction of the rotating part 11, and both ends of the elastic element 12 are respectively connected to the first cleaning mechanism 20 and the main unit 10. For example, the elastic element 12 in this application can be a spring, an elastic rubber strip, etc. Through the action of the elastic element 12, when an obstacle applies a force to the first cleaning mechanism 20, the elastic element 12 can maintain the current position of the first cleaning mechanism 20, which is more suitable for making the flexible mop 222 on the first cleaning component 22 continuously contact the edge of the obstacle to perform cleaning operations. That is to say, the setting of the elastic element 12 allows the flexible mop 222 of the first cleaning component 22 to adhere to the obstacle for edge cleaning, and facilitates the flexible retraction of the first cleaning component 22.

[0101] like Figure 5 As shown, in order to limit and guide the elastic element 12, the main unit 10 in this application is provided with an arc-shaped groove 13. The center of the arc-shaped groove 13 coincides with the rotation center of the rotating part 11. The elastic element 12 is installed in the arc-shaped groove 13 and can extend and retract along the extension direction of the arc-shaped groove 13. Optionally, the two ends of the elastic element 12 in this application can be fixed to the main unit 10 and the first cleaning mechanism 20 respectively by means of hooks, buckles, welding, etc. Any other modifications under the concept of this application are within the protection scope of this application.

[0102] Further, see Figure 4 , Figure 5 , Figure 8 , Figures 17 to 21 As shown, the first cleaning mechanism 20 also includes a first power component 21, which includes a first drive member 211 and a first transmission assembly 212. The first transmission assembly 212 is rotatably mounted on the main unit 10, and the housing of the first drive member 211 is fixedly connected to the housing of the first transmission assembly 212. The first drive member 211 has a rotating shaft, which can be coaxially or separately mounted with the rotating part 11. The first transmission assembly 212 connects the first drive member 211 and the first cleaning component 22. The first drive member 211 drives the first transmission assembly 212 via the rotating shaft to drive the first cleaning component 22 to rotate in a first direction or a second direction. The first transmission assembly 212 is provided with an engagement port 23133, which is at least used to engage with the limiting member 60 and actuate the limiting member 60 from the second state to the first state when the first cleaning component 22 rotates in the first direction.

[0103] Specifically, the first power component 21 is mainly used to drive the first cleaning component 22 to move between the retracted position and the outward expansion position, and to drive the first cleaning component 22 to rotate along the first direction or the second direction. The cleaning device 100 of this application can use one first power component 21 to drive the first cleaning mechanism 20 to move (i.e., move between the retracted position and the outward expansion position) and to drive the first cleaning component 22 to rotate (i.e., rotate along the first direction or the second direction). Alternatively, multiple first power components 21 can be used to collaboratively drive the first cleaning mechanism 20 to move and to drive the first cleaning component 22 to rotate. This embodiment shows the case where the cleaning device 100 uses one first power component 21 to drive the first cleaning mechanism 20 to move and to drive the first cleaning component 22 to rotate. The first driving component 211 in this application includes a motor, and the rotating shaft of the motor and the rotating part 11 can be coaxially arranged, such as... Figure 4 and Figure 5 As shown, this optimizes the space occupied by the first power unit 21 when it swings relative to the main unit 10, making it more suitable for the rational layout of the components on the cleaning device 100. Furthermore, the motor shaft and the rotating part 11 can also be separated, as shown... Figures 17 to 21 As shown, the motor and the first transmission assembly 212 are connected and then encapsulated together within the housing of the first transmission assembly 212. The housing of the first transmission assembly 212 is then rotatably connected to the rotating part 11. Thus, the motor and the first transmission assembly 212 can rotate around the rotating part 11, thereby driving the first cleaning component 22 to switch between an outward-expanding position and an inward-retracting position. During this process, when the first cleaning component 22 rotates in the first direction, the motor and the first transmission assembly 212 can swing around the rotating part 11 in the second direction. When the first transmission assembly 212 rotates to the limiting component 60, the engagement port 23133 provided on the first transmission assembly 212 can engage with the limiting component 60, thereby causing the limiting component 60 to rotate in the second direction, causing the limiting component 60 to switch from the second state to the first state. This allows the limiting component 60 to avoid the first transmission assembly 212, thereby allowing the first cleaning component 22 to switch from the inward-retracting position to the outward-expanding position.

[0104] For example, the rotating part 11 in this application includes a rotating shaft and other structures. In actual installation, a bearing is installed on the first driving member 211, i.e. the housing of the motor, and the bearing is fixedly sleeved on the rotating shaft. Any other modifications under the concept of this application are within the protection scope of this application.

[0105] Further, see Figure 22As shown, the width of the limiting component 60 is d1, and the width of the engagement port 23133 is d2. d1 and d2 satisfy the relationship: d1 < d2. When the limiting component 60 engages with the engagement port 23133, there is a gap between the limiting component 60 and the engagement port 23133. The width of the gap is D, and the depth of the engagement port 23133 is G. D and G satisfy the relationship:

[0106] Specifically, the depth of the engagement port 23133 is the depth of the engagement port 23133 extending radially along the second transmission member 2313, and the width of the gap is the width of the gap extending radially along the second transmission member 2313. In this application, the width D of the gap is set to be greater than or equal to but less than 1 / 3 of the depth G of the engagement port 23133 (i.e., This is because this arrangement allows for better engagement between the second transmission component 2313 and the limiting component 60. The reason the gap width D can be zero is that gaps exist between the fixed spindle 142 and the limiting component 61, as well as between the torsion spring 621, and between the flexible mop 222 and the shaft supporting its rotation. This increases the gap width D. Therefore, in actual installation, the gap width D can be set to zero to prevent the second transmission component 2313 from disengaging from the limiting component 60. If the gap width D is greater than 1 / 3 of the depth G of the engagement opening 23133, during engagement between the second transmission component 2313 and the limiting component 60, tooth disengagement is likely to occur, preventing the second transmission component 2313 from effectively rotating the limiting component 60. Therefore, this application sets the gap width D to be greater than 1 / 4 of the depth G of the engagement opening 23133 but less than 1 / 3 of the depth G of the engagement opening 23133.

[0107] In some embodiments of this application, the cleaning device 100 may be provided with only one cleaning mechanism, namely the first cleaning mechanism 20 (as shown in Figures 1 to 20). Figure 5 (As shown). In some other embodiments of this application, the cleaning device 100 may also be provided with multiple cleaning mechanisms, such as... Figures 6 to 10As shown, the cleaning device 100 includes two cleaning mechanisms, which are designated as the first cleaning mechanism 20 and the second cleaning mechanism 30 for ease of operation. When the cleaning device 100 has two cleaning mechanisms, it is configured such that: when the first cleaning component 22 of the first cleaning mechanism 20 rotates in a first direction and is subjected to a torque in a second direction, the first cleaning component 22 of the first cleaning mechanism 20 swings relative to the main unit 10 in the second direction to an outward position, and the second cleaning component 32 of the second cleaning mechanism 30 rotates in the second direction; when the first cleaning component 22 of the first cleaning mechanism 20 rotates in the second direction and is subjected to a torque in the first direction, the first cleaning component 22 of the first cleaning mechanism 20 swings relative to the main unit 10 in the first direction to an inward position, and the second cleaning component 32 of the second cleaning mechanism 30 rotates in the first direction. That is, when the first cleaning component 22 rotates in the first direction, the second cleaning component 32 rotates in the second direction; when the first cleaning component 22 rotates in the second direction, the second cleaning component 32 rotates in the first direction.

[0108] Combination Figures 6 to 10 , Figures 12 to 14 As shown, in the cleaning device 100, when the first cleaning mechanism 20 is subjected to frictional torques in different directions (such as when the first cleaning mechanism 20 rotates and contacts the ground, the first cleaning mechanism 20 will be subjected to frictional torques from the ground), the first cleaning mechanism 20 can swing relative to the main unit 10, thereby achieving the swaying of the first cleaning mechanism 20. At the same time, the second cleaning mechanism 30 rotates in the opposite direction to the first cleaning mechanism 20, and the frictional forces subjected to the second cleaning mechanism 30 and the first cleaning mechanism 20 can cancel each other out, thereby ensuring the stability of the cleaning device 100 during operation.

[0109] When the cleaning device 100 simultaneously has a first cleaning mechanism 20 and a second cleaning mechanism 30, at least one of the first cleaning mechanism 20 and the second cleaning mechanism 30 can swing relative to the main unit 10. (This application's appendix...) Figure 10 The diagram illustrates a scenario where the first cleaning mechanism 20 can swing relative to the host 10, while the second cleaning mechanism 30 cannot. Of course, in other embodiments of this application, the second cleaning mechanism 30 can also swing relative to the host 10. When both the first cleaning mechanism 20 and the second cleaning mechanism 30 can swing relative to the host 10, the structures of the first cleaning mechanism 20 and the second cleaning mechanism 30 are identical, but the rotation directions of the first cleaning component 22 and the second cleaning component 32 are opposite.

[0110] Further, see Figure 12 , Figure 13 as well as Figures 17 to 25As shown, the first transmission assembly 212 includes a first transmission member 2312 and a second transmission member 2313. A first driving member 211 is driven to connect with the first transmission member 2312 to drive the first transmission member 2312 to rotate in a first direction or a second direction. The first transmission member 2312 and the second transmission member 2313 abut against each other. The second transmission member 2313 rotates in the first direction or the second direction under the drive of the first transmission member 2312 and rises or falls in the height direction of the host 10. The engagement port 23133 is provided on the outer surface of the second transmission member 2313. When the first cleaning member 22 is in the retracted position, the limiting member 60 is misaligned with the second transmission member 2313 in the projection of the host 10 in the height direction. When the first cleaning member 22 switches between the retracted position and the outward position, the second transmission member 2313 contacts the limiting member 60 and moves the limiting member 60 through the engagement port 23133 to switch the limiting member 60 from the second state to the first state.

[0111] Specifically, through the cooperation of the first transmission member 2312 and the second transmission member 2313, efficient power transmission from the first drive member 211 to the second transmission member 2313 is achieved, ensuring the stability and reliability of rotation. The second transmission member 2313 can not only rotate in a specific direction (first direction or second direction) under the drive of the first transmission member 2312, but also rise or fall along the height direction of the main unit 10, thereby realizing the vertical position adjustment of the cleaning component (first cleaning component 22 or second cleaning component 32, mainly referring to the first cleaning component 22 in this embodiment), enhancing the adaptability of the cleaning device 100. In this application, when the first cleaning component 22 is in the retracted position, the limiting component 60 and the second transmission component 2313 are misaligned within the projection of the main unit 10 in the height direction. That is, the limiting component 60 and the second transmission component 2313 do not contact each other at this time. This arrangement is because when the first cleaning component 22 is in the retracted position, it is necessary to prevent the limiting component 60 from interfering with the movement of the second transmission component 2313, thereby allowing the first cleaning component 22 to perform its cleaning work more effectively. If, when the first cleaning component 22 is in the retracted position, the projections of the limiting component 60 and the second transmission component 2313 overlap within the projection of the main unit 10 in the height direction, that is, the limiting component 60 and the second transmission component 2313 may come into contact. This would not only interfere with the movement of the second transmission component 2313 but also accelerate the wear of the limiting component 60 and the second transmission component 2313, reducing their service life and potentially even affecting the lifespan of the entire cleaning device.

[0112] This application describes the second cleaning mechanism 30 in detail as being unable to swing relative to the main unit 10. In this embodiment, the second power component 31 of the second cleaning mechanism 30 is fixedly mounted on the main unit 10. The second power component 31 has a second drive member 311 and a second transmission assembly 312. The second drive member 311 is a drive motor. Both the second transmission assembly 312 and the first transmission assembly 212 include a reduction gearbox 2311, a first transmission member 2312, a second transmission member 2313, and an elastic element 2314. The first transmission member 2312 connects the reduction gearbox 2311 and the second transmission member 2313. The second transmission member 2313 connects the first cleaning member 22 or the second cleaning member 32. The second transmission member 2313 has a track surface 23131. The first transmission member 2312 is movably held against the track surface 23131. The elastic element 2314 holds against the second transmission member 2313 to apply a restoring force to the second transmission member 2313.

[0113] The gearbox 2311 is configured to drive the first transmission member 2312 to rotate along the first direction and the second direction under the drive of the first drive member 211 or the second drive member 311, so that the first transmission member 2312 moves on the track surface 23131, and the first cleaning member 22 moves up and down along the height direction of the host 10 and rotates along the first direction or the second direction.

[0114] In the initial state, the first cleaning component 22 and the second cleaning component 32 are positioned relatively high on the main unit 10, i.e., the first cleaning component 22 and the second cleaning component 32 are off the ground or tabletop. When the gearbox 2311 drives the first transmission component 2312 to rotate in the first direction, the first transmission component 2312 abuts against the track surface 23131 and rotates along the track surface 23131. In this application, the track surface 23131 is a convex arc surface. As the first transmission component 2312 moves from a low position to a high position along the track surface 23131, the first transmission component 2312 applies a resisting force to the second transmission component 2313, which can cause the second transmission component 2313 to move away from the first transmission component 2312, i.e., move towards the ground along the height direction of the main unit 10. This can then drive the first cleaning component 22 or the second cleaning component 32 connected to the second transmission component 2313 to move towards the ground. The second transmission component 2313 in this application is provided with a limiting structure 23132. When the first cleaning component 22 and the second cleaning component 32 are in contact with the ground, the reduction gearbox 2311 continuously drives the first transmission component 2312 to move along the height direction of the host 10. At this time, the side of the first transmission component 2312 is in contact with the limiting structure 23132. The second transmission component 2313 can rotate along the first direction under the drive of the first transmission component 2312 to clean the ground. During this process, the first cleaning mechanism 20 is subjected to the frictional torque applied by the ground and can swing relative to the host 10 along the second direction to drive the first cleaning component 22 to switch to the outward expansion position to clean the obstacles along the edge. Since the second driving component 311 of the second cleaning mechanism 30 is fixed, the second cleaning component 32 remains in a fixed position relative to the host 10 and performs cleaning operations in place. It should be noted that the rotation direction of the reduction gearbox 2311 in the second cleaning mechanism 30 is always opposite to the rotation direction of the reduction gearbox 2311 in the first cleaning mechanism 20 to ensure that the cleaning device 100 can operate smoothly.

[0115] When the gearbox 2311 drives the first transmission member 2312 to rotate in a second direction opposite to the first direction, the first transmission member 2312 disengages from the limiting structure 23132. The first transmission member 2312 rotates from the highest position of the track surface 23131 to the lowest position of the moving track surface 23131. During this process, the elastic element 2314 applies a restoring force to the second transmission member 2313, that is, applies a supporting force away from the ground along the height direction of the host 10. At this time, the second transmission member 2313 rises in a direction away from the ground, which can drive the first cleaning component 22 and the second cleaning component 32 to rise and detach from the ground.

[0116] As can be seen, the first cleaning component 22 and the second cleaning component 32 in this application can rise and fall, which helps to protect the ground and reduces the difficulty of the cleaning device 100 in overcoming obstacles.

[0117] Specifically, along the height direction of the main unit 10, the first transmission component 2312 can be connected below the reduction gearbox 2311. The first transmission component 2312 can be U-shaped and is fixedly mounted on the reduction gearbox 2311 or the output shaft 23111 of the motor. In this case, the output shaft 23111 of the motor or reduction gearbox 2311 extends along the height direction of the main unit 10. The second transmission component 2313 is cylindrical and is sleeved on the output shaft 23111 and can move up and down relative to the output shaft 23111. The elastic element 2314 can be a spring, elastic sleeve, or other structure. The elastic element 2314 is capable of elastic deformation and is sleeved on the output shaft 23111. A support block 23112 is provided at the bottom end of the output shaft 23111. The two ends of the elastic element 2314 abut against the second transmission member 2313 and the support block 23112, respectively. After being compressed by the second transmission member 2313, the elastic element 2314 can recover its elastic deformation, causing it to extend and push the second transmission member 2313 to move along the output shaft 23111. The first cleaning component 22 or the second cleaning component 32 is fixedly connected below the second transmission member 2313. A limiting structure 23132 is provided on the inner or outer wall surface of the second transmission member 2313.

[0118] In this application, the trajectory surface 23131 can be disposed on the outer peripheral surface of the second transmission member 2313, or it can be disposed on the inner wall surface of the second transmission member 2313. (See attached diagram of this application.) Figure 14 The diagram shows the case where the trajectory surface 23131 is disposed on the outer peripheral surface of the second transmission member 2313. The limiting structure 23132 is disposed on the trajectory surface 23131 and located at the top of the trajectory surface 23131. In this application, the limiting structure 23132 can be a protrusion structure, consisting of two protrusions respectively disposed on opposite sides of the second transmission member 2313. During actual operation, the two ends of the U-shaped first transmission member 2312 abut against the trajectory surface 23131 between the two limiting structures 23132 and slide along the trajectory surface 23131 to drive the second transmission member 2313 to rise and fall in the first direction. When the two ends of the U-shaped first transmission member 2312 are stopped by the two limiting structures 23132, the second transmission member 2313 rises and falls to its limit position in the first direction.

[0119] In some implementations, please refer to Figures 12 to 14As shown, the trajectory surface 23131 includes a first region 23131a, a second region 23131b, a third region 23131c, and a connecting region 23131d. In the circumferential direction of the second transmission member 2313, the first region 23131a, the second region 23131b, and the third region 23131c are sequentially connected, with the second region 23131b lower than the first region 23131a and the third region 23131c. Adjacent regions can be connected via the connecting region 23131d, and the first transmission member 2312 can move from one region to another via the connecting region 23131d. When the first transmission member 2312 abuts against the first region 23131a or the third region 23131c, the first cleaning component 22 or the second cleaning component 32 is in a cleaning position that abuts against the ground. When the first transmission member 2312 abuts against the second region 23131b, the first cleaning component 22 or the second cleaning component 32 is in a position that allows it to detach from the ground. Thus, through the three areas of the trajectory surface 23131, the first cleaning component 22 or the second cleaning component 32 can switch between the ground-lift position and the cleaning position.

[0120] Further, see Figures 22 to 24 As shown, the second transmission member 2313 includes an annular protrusion 23134, which extends along the outer peripheral surface of the second transmission member 2313. The engagement port 23133 is disposed on the annular protrusion 23134 and recessed along the radial direction of the annular protrusion 23134.

[0121] Specifically, the design of the annular protrusion 23134 not only provides a suitable machining position for the engagement port 23133, but also saves materials to a certain extent. Without the annular protrusion 23134, the size of the second transmission component 2313 would need to be enlarged in the radial direction, leading to unnecessary material waste and increased weight, which would affect its start-up and shutdown. Furthermore, the increased size of the second transmission component 2313 would also increase the space it occupies in the main unit 10, hindering the saving of internal installation space. Moreover, the annular protrusion 23134 allows the second transmission component 2313 to effectively contact the limiting component 60 during rotation, enabling it to move the limiting component 60 between the first and second states via the engagement port 23133.

[0122] Further, see Figures 22 to 24As shown, the second transmission member 2313 also includes a baffle 23135. The baffle 23135 is disposed on the outer surface of the second transmission member 2313 and extends along the height direction of the second transmission member 2313. The meshing port 23133 is disposed at the first position of the annular protrusion 23134. The position where the baffle 23135 and the annular protrusion 23134 intersect is the second position. The first position and the second position are offset.

[0123] Specifically, the baffle 23135 can extend along the height direction of the second transmission member 2313 to the annular protrusion 23134, or it can extend along the height direction of the second transmission member 2313 and be spaced apart from the annular protrusion 23134. This embodiment shows the case where the baffle 23135 extends along the height direction of the second transmission member 2313 to the annular protrusion 23134. The baffle 23135 not only improves the structural strength of the second transmission member 2313 to a certain extent, but also makes the connection between the first transmission member 2312 and the second transmission member 2313 more effective, avoiding radial misalignment between the first transmission member 2312 and the second transmission member 2313 during the process of the first transmission member 2312 driving the second transmission member 2313, which would prevent the normal transmission of movement from the first transmission member 2312 to the second transmission member 2313. Furthermore, the engagement port 23133 is located at the first position of the annular protrusion 23134, and the position where the retaining rib 23135 intersects with the annular protrusion 23134 is the second position. The first and second positions are offset, meaning that along the height direction of the main unit, the retaining rib 23135 and the engagement port 23133 are not on the same axis. This arrangement prevents stress concentration from affecting the structural strength of the second transmission component 2313 and also prevents the retaining rib 23135 from interfering with the movement of the limiting component 60, thus allowing the second transmission component 2313 and the limiting component 60 to complete their respective functions.

[0124] Further, see Figure 10 , Figures 22 to 24 As shown, the second transmission member 2313, under the support of the first transmission member 2312, has the ability to rise to the highest first limit position along the height direction of the main unit 10, or to descend to the lowest second limit position along the height direction of the main unit 10; along the height direction of the main unit 10, the height of the limiting member 60 (i.e., Figure 23 and Figure 24 The thickness of H in the figure is greater than the thickness of the annular protrusion 23134 (i.e. Figure 23 and Figure 24In the case of h), the height of the limiting component 60 is greater than or equal to the maximum stroke of the second transmission component 2313 in the height direction. When the first cleaning component 22 is in the first limit position, the top of the limiting component 60 is higher than or equal to the top of the annular protrusion 23134. When the first cleaning component 22 is in the second limit position, the bottom of the limiting component 60 is lower than or equal to the bottom of the annular protrusion 23134.

[0125] Specifically, when the second transmission member 2313 rises to the first limit position along the height direction of the main unit 10 under the support of the first transmission member 2312, the cooperation relationship between the first transmission member 2312, the second transmission member 2313, and the limiting member 60 is as follows: Figure 22 As shown, at this time, the first cleaning component 22 rises to its highest position along the height direction of the main unit 10 with the second transmission component 2313. The first cleaning component 22 does not contact the surface to be cleaned (which can be the ground or a tabletop), and the first cleaning component 22 is in a non-working state (not cleaning the surface to be cleaned). When the second transmission component 2313 descends to its lowest second limit position along the height direction of the main unit 10 under the support of the first transmission component 2312, the cooperation relationship between the first transmission component 2312, the second transmission component 2313, and the limiting component 60 is as follows: Figure 23 As shown, at this time, the first cleaning component 22 descends to its lowest position along the height direction of the main unit 10 along with the second transmission component 2313, and the first cleaning component 22 contacts the surface to be cleaned, and the first cleaning component 22 is in working state (cleaning the surface to be cleaned). In this application, the reason why the height of the limiting component is set to be greater than the thickness of the annular protrusion (i.e., H > h) is that this setting can ensure that the second transmission component 2313 and the limiting component 61 can effectively contact each other during the process of the second transmission component 2313 rising or falling along the height direction of the main unit 10, and this design can also simplify the assembly process between the second transmission component 2313 and the limiting component 61. In addition, when the first cleaning component 22 is in the first extreme position, the top of the limiting component 61 is higher than the top of the annular protrusion 23134 (i.e., Figure 23 As shown), or at the same height as the top of the annular protrusion 23134, when the first cleaning component 22 is in the second extreme position, the bottom of the limiting member 61 is lower than the bottom of the annular protrusion 23134 (i.e., as shown). Figure 24(As shown), or at the same height as the bottom of the annular protrusion 23134. This design not only ensures effective contact between the second transmission member 2313 and the limiting member 61 in the height direction of the host, but also prevents the first cleaning member 22 from disengaging from the top or bottom of the limiting member 61 when it is in the first or second extreme position. Furthermore, to further ensure that the second transmission member 2313 does not disengage from the limiting member 61 during its ascent or descent along the height direction of the host 10, the height of the limiting member 61 is always greater than or equal to the maximum stroke of the second transmission member 2313 in the height direction.

[0126] Further, see Figure 21 As shown, the first cleaning mechanism 20 also includes a first stop component 23, which is disposed on the first cleaning mechanism 20 and has a clearance opening 2321. The clearance opening 2321 is at least used to avoid the limiting component 60 to prevent interference between the first stop components 23 and the first stop component 23. When the first cleaning component 22 protrudes from the edge of the main unit 10 to clean and comes into contact with an obstacle, the first stop component 23 is driven by the force exerted by the obstacle to cause the first cleaning mechanism 20 to swing, thereby causing the first cleaning component 22 to move towards the inward position.

[0127] Specifically, the clearance opening 2321 allows the first stop component 23 to avoid the limiting component 60. This ensures that the first stop component 23 will not interfere with the limiting component 60 during the swinging of the first cleaning mechanism 20 in the first or second direction. It also ensures that during the transition between the outward and inward positions of the first cleaning component 22, the limiting component 61 can pass through the clearance opening 2321 to the inside of the first stop component 23 and contact the second transmission component 2313, allowing the limiting component 60 to transition from the second state to the first state under the influence of the second transmission component 2313. Furthermore, when the first cleaning component 22 protrudes from the edge of the main unit 10 and comes into contact with an obstacle, the force exerted by the obstacle on the first stop component 23 can cause the first cleaning mechanism 20 to swing, thereby moving the first cleaning component 22 towards the inward position. This achieves passive inward retraction of the first cleaning component 22, preventing it from being ejected by the force exerted by the obstacle. Once the force exerted by the obstacle disappears, the first cleaning component 22 can move back towards the outward expansion position to continue cleaning along the edge.

[0128] Further, see Figure 12 , Figure 13 as well as Figure 21As shown, the first transmission assembly 212 further includes a reduction gearbox 2311, and the first stop component 23 includes a connecting portion 232 and a stop plate 231; the connecting portion 232 is integrally formed or fixedly connected to the outer shell of the reduction gearbox 2311, and the connecting portion 232 surrounds the outer periphery of the first transmission component 2312 and the second transmission component 2313, the clearance opening 2321 is located at the connecting portion 232, the stop plate 231 is integrally formed or fixedly connected to the connecting portion 232, and the stop plate 231 covers part of the outer periphery of the first cleaning component 22; the power input end of the reduction gearbox 2311 is connected to the first driving component 211, and the power output end of the reduction gearbox 2311 is connected to the first transmission component 2312 to drive the first transmission component 2312 to rotate in a first direction or a second direction.

[0129] Specifically, the gearbox 2311 is typically used to reduce the motor speed while increasing the output torque. This means that by adjusting the motor's output speed and torque, the rotational movement of the first transmission component 2312 can be more precisely controlled, thereby further controlling the first cleaning component 22 to perform cleaning work. The connecting part 232 is integrally formed or fixedly connected to the housing of the gearbox 2311 and surrounds the outer periphery of the first transmission component 2312 and the second transmission component 2313. This design helps protect the first transmission component 2312 and the second transmission component 2313 from the influence of the external environment, such as dust and debris, and also prevents other components of the cleaning device 100 from interfering with the movement of the first transmission component 2312 and the second transmission component 2313. Furthermore, the stop plate 231 is integrally formed or fixedly connected to the connecting portion 232, and the stop plate 231 covers part of the outer periphery of the first cleaning component 22. This allows the stop plate 231 to be the first to contact a wall or obstacle when the first cleaning component 22 is in an outward-expanding position for cleaning, thus providing excellent protection for the first cleaning component 22. Additionally, the clearance opening 2321 on the connecting portion 232 can extend along the outer periphery of the connecting portion 232, and the specific position and size of the clearance opening 2321 on the connecting portion 232 can be reasonably adjusted according to actual conditions, as long as it ensures that the first stop component 23 does not interfere with the movement of the limiting component 60. The power input end of the gearbox 2311 is connected to the first drive member 211, and the power output end of the gearbox 2311 is connected to the first transmission member 2312, so that the first drive member 211 can effectively drive the first transmission member 2312 to rotate in two directions (the first direction and the second direction) through the gearbox 2311. This arrangement not only improves the flexibility of operation, but also enhances the adaptability of the internal system of the cleaning device 100 and the cleaning efficiency of the cleaning device 100.

[0130] Further, see Figures 2 to 5 , Figure 8 as well as Figure 13As shown, the first cleaning component 22 also includes a mop bracket 221 and a flexible mop 222. In the projection along the height of the main unit 10, the flexible mop 222 protrudes beyond the outer edge of the mop bracket 221. A stop plate 231 is located inside the flexible mop 222, and at least partially protrudes beyond the outer edge of the mop bracket 221. Thus, when the first cleaning component 22 is in its outward-expanding position and encounters an obstacle while cleaning along its edge, the edge of the flexible mop 222 can continue to clean the edge of the obstacle. If the first cleaning component 22 collides with an obstacle, the stop plate 231 can contact the obstacle, thereby providing good protection for the mop bracket 221 and preventing scratches on both the mop bracket 221 and the obstacle (when the obstacle is a table leg or a wall, scratches need to be prevented).

[0131] Combination Figures 1 to 25 As shown, the cleaning device 100 in this application also includes a central sweeping mechanism 40 and a set of moving wheels 50. The central sweeping mechanism 40 is located at the center of the bottom of the main unit 10, and the set of moving wheels 50 is located at the bottom of the main unit 10. The set of moving wheels 50 is driven by a motor or other drive mechanism. In actual operation, by controlling the motor or other drive mechanism, the main unit 10 can be moved within space. During this process, by acting on the first power component 21 and the second power component 31, the first cleaning component 22 and the second cleaning component 32 can be raised, lowered, and rotated to clean the floor or countertop. At the same time, the frictional torque generated by the first power component 21 driving the first cleaning component 22 to rotate can cause the first cleaning component 22 to expand outward to clean the edges of obstacles. Furthermore, as the first cleaning mechanism 20 rotates relative to the main unit 10, the first stop component 23 can move synchronously with the first cleaning mechanism 20. When the first cleaning component 22 approaches an obstacle, the first stop component 23 can contact the obstacle in the space, preventing the first cleaning component 22 from scratching the obstacle during edge cleaning and facilitating edge cleaning of the obstacle, thus avoiding missed areas. Additionally, when the first cleaning component 22 contacts an obstacle, it can apply a reaction force to the first cleaning mechanism 20, causing the first cleaning mechanism 20 to retract and move towards the retracted position. This allows the first cleaning mechanism 20 to achieve flexible retraction without the need for additional detection mechanisms or control logic, resulting in a simple structure that effectively improves the user comfort and design cost of the cleaning device 100.

[0132] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0133] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0134] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
