Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more particularly to a cleaning module and cleaning equipment. Background Technology

[0002] Due to the size limitations of cleaning equipment, there are often blind spots during the cleaning process. In order to reduce these blind spots, some cleaning equipment has added an outward expansion function for cleaning components. By expanding the cleaning components, the size limitations of the cleaning equipment can be reduced, and the cleaning range of the cleaning equipment can be increased.

[0003] When the cleaning component extends outwards during cleaning, the force on the extended part of the cleaning component and the part located below the main body of the equipment is uneven, which makes it easy for the cleaning component and the main body of the equipment to move relative to each other. This causes the cleaning component to be unable to maintain downward pressure, thus affecting the cleaning effect. Summary of the Invention

[0004] This application provides a cleaning module and cleaning equipment to improve the technical problem that the cleaning component is prone to relative movement with the main body of the equipment during external cleaning, which makes it impossible for the cleaning component to maintain downward pressure.

[0005] The first aspect of this application provides a cleaning module, which includes a first support, a second support, a drive mechanism, a cleaning component, a lifting structure, and a locking mechanism. The first support is configured to be connected to the main body of a cleaning device; the second support is slidably mounted on the first support in a horizontal direction, and the second support has an outwardly extended position, an inwardly retracted position, and a retracted position relative to the first support; the drive mechanism drives the second support to move relative to the first support; the cleaning component is movably mounted on the second support; the lifting structure is disposed on the cleaning component and / or the second support, such that when the second support moves relative to the first support between the inwardly retracted position and the retracted position, it drives the cleaning component to move between a falling position and a raised position; the locking mechanism is disposed on the second support, and at least when the second support is in the outwardly extended position, the locking mechanism restricts the sliding of the cleaning component relative to the second support, so as to keep the cleaning component in the falling position.

[0006] The cleaning module of this application includes a first bracket and a second bracket. The second bracket is slidably mounted on the first bracket in the horizontal direction. The second bracket has an expanded position, a retracted position, and a retracted position relative to the first bracket. When the second bracket moves between the expanded and retracted positions, it drives the cleaning component to move synchronously. The cleaning component is always in the lowered position, but switches between the expanded state and the normal state. When the second bracket moves between the retracted and retracted positions, the cleaning component is always in the normal state, but its horizontal movement is restricted, causing the second bracket to drive the cleaning component to switch between the lowered position and the raised position. By driving the relative movement of the second bracket and the first bracket through a drive mechanism, the switching between the expanded state and the normal state of the cleaning component can be realized. The normal state refers to the state where the cleaning component is retracted into the main body of the device. On the other hand, in conjunction with the lifting mechanism, the switching between the lowered position and the raised position of the cleaning component can be realized. The movement of the cleaning component in the horizontal and vertical directions is realized through a single drive mechanism, reducing the number of drive mechanisms and lowering the drive cost.

[0007] The lifting structure can be installed on the cleaning component, so that when the second support moves horizontally, the lifting structure drives the cleaning component to move vertically; the lifting structure can also be installed on the second support, so that when the second support moves horizontally, the lifting structure drives the cleaning component to move vertically; the lifting structure includes two or more parts respectively installed on the cleaning component and the second support, so that when the second support moves horizontally, the lifting structure drives the cleaning component to move vertically.

[0008] The cleaning module of this application includes a locking mechanism. When the second support is in the extended position, the locking mechanism restricts the sliding of the cleaning component relative to the second support, thereby preventing the cleaning component from moving from the falling position to the rising position due to relative sliding with the second support. The cleaning component remains in the falling position under the weight of the device body, possessing sufficient downward pressure to ensure full contact with the surface to be cleaned, guaranteeing the cleaning effect and improving the problem of the cleaning component losing downward pressure in the extended state.

[0009] In an exemplary embodiment of this application, the lifting structure includes a lifting part and a sliding member. The lifting part is disposed on one of the second bracket and the cleaning component, and at least a portion of the surface of the lifting part is an inclined lifting surface; the sliding member is disposed on the other of the second bracket and the cleaning component, and the sliding member abuts against the lifting part. When the sliding member moves relative to the lifting part along the lifting surface, it has horizontal and vertical components.

[0010] The lifting unit can be mounted on the second support, and the sliding member can be mounted on the cleaning component. The sliding member moves relative to the lifting unit along the lifting surface, thereby enabling the second support to move horizontally and thus driving the cleaning component to move vertically. Alternatively, the lifting unit can be mounted on the cleaning component, and the sliding member can be mounted on the second support. The sliding member moves relative to the lifting unit along the lifting surface, thereby enabling the second support to move horizontally and thus driving the cleaning component to move vertically.

[0011] Preferably, the lifting part can be disposed on the second bracket, and the sliding member can be disposed on the cleaning component. Along the direction of movement of the second bracket from the inward position to the receiving position, the lifting surface is inclined downward, so that when the second bracket moves from the inward position to the receiving position, the sliding member moves along the surface of the lifting surface, causing the cleaning component to be lifted upward to the lifting position.

[0012] By using the cooperation of the sliding part and the lifting part, the second bracket moves horizontally, driving the cleaning component to move vertically. In turn, a drive mechanism enables the cleaning component to move in both the horizontal and vertical directions, reducing the number of drive mechanisms required and lowering production costs.

[0013] In an exemplary embodiment of this application, the locking mechanism includes a rocker arm and a drive member. The rocker arm is rotatably mounted on a second bracket and has a restricted position and an open position relative to the second bracket. When the rocker arm is in the restricted position, it is within the path of relative movement between the sliding member and the lifting part, thereby restricting the relative movement of the sliding member along the lifting surface and the lifting part. The drive member is used to drive the rocker arm to rotate relative to the second bracket. The drive member causes the rocker arm to move between the restricted position and the open position, or the drive member cooperates with the first bracket or the device body to cause the rocker arm to move between the restricted position and the open position.

[0014] The driving component can drive the swing arm to move between the restricted position and the open position independently, or the driving component can work in conjunction with the first bracket or the main body of the device to make the swing arm move between the restricted position and the open position.

[0015] When the swing arm is in the restricted position relative to the second bracket, it lies within the path of relative movement between the sliding member and the lifting part, thus restricting the relative movement of the sliding member along the lifting surface and the lifting part, keeping the cleaning component in the falling position. When the cleaning component is in the falling position, it is affected by the gravity of the main body of the equipment, ensuring the pressure of the cleaning component on the surface to be cleaned, thereby ensuring the cleaning effect on the surface.

[0016] When the swing arm is in the open position relative to the second support, it disengages from the path of relative movement between the sliding member and the lifting unit. The sliding member can then move relative to the lifting unit, allowing the cleaning component to move relative to the second support. The cleaning component can switch between a lowering position and a raised position. In the lowering position, the cleaning component cleans the surface to be cleaned. In the raised position, it facilitates the cleaning equipment's movement over obstacles and prevents contamination of the ground after cleaning or when cleaning is required, thus ensuring effective cleaning.

[0017] In an exemplary embodiment of this application, the first bracket includes a support plate, and the second bracket is located above the support plate. A first notch is provided on the support plate. When the end of the swing rod is inserted into the first notch, it is in an open position, and when the end of the swing rod abuts against the upper surface of the support plate, it is in a restricted position. The driving member applies a force to the swing rod so that the swing rod has a tendency to move from the open position to the restricted position, so that when the end of the swing rod disengages from the upper surface of the support plate, the end of the swing rod is inserted into the first notch.

[0018] When the lever is not inserted into the first notch, the lever is located within the path of relative movement between the slider and the lifting part, thereby restricting the relative movement of the slider along the lifting surface and the lifting part, and thus restricting the relative movement between the cleaning component and the second bracket, so that the cleaning component is kept in the falling position.

[0019] When the second bracket moves relative to the first bracket, causing the end of the swing arm to detach from the upper surface of the support plate and be able to be inserted into the first notch, the driving component drives the swing arm to insert into the first notch, causing the swing arm to detach from the sliding component and move along the path of relative movement between the lifting surface and the lifting part, so that the swing arm moves to the open position.

[0020] In an exemplary embodiment of this application, the drive member includes a torsion spring, one end of which abuts against a second bracket and the other end against a rocker arm. The torsion spring applies a force to the rocker arm to move from an open position to a restricted position, so that when the end of the rocker arm disengages from the upper surface of the support plate, the end of the rocker arm inserts into a first notch.

[0021] The torsion spring applies force to the rocker arm. On one hand, it presses the rocker arm against the support plate of the second bracket, preventing it from disengaging from the path of relative movement between the sliding member and the lifting part. On the other hand, when the second bracket moves relative to the first bracket, causing the end of the rocker arm to disengage from the support plate surface to the first notch, the torsion spring allows the rocker arm to insert into the first notch, disengaging it from the path of relative movement between the sliding member and the lifting part. This allows the sliding member and the lifting part to move relative to each other, and consequently, the cleaning assembly and the second bracket to move relative to each other, enabling the cleaning assembly to move between the lowering and raising positions. The torsion spring is characterized by stable force and long durability, ensuring stable movement of the rocker arm and the proper functioning of the locking mechanism.

[0022] In an exemplary embodiment of this application, a lifting part is disposed on a second bracket, and the lifting part includes a first bearing surface, a second bearing surface, and a mounting groove. The first bearing surface is parallel to the horizontal direction and is located at the bottom end of the lifting surface; the second bearing surface is parallel to the horizontal direction and is disposed at the top end of the lifting surface; the mounting groove is disposed on the side of the lifting part near the support plate; the mounting groove extends through the lifting part at least vertically; and the swing arm is rotatably mounted in the mounting groove.

[0023] The first bearing surface is a surface parallel to the horizontal direction. The first bearing surface is located at the bottom of the lifting surface. When the cleaning component is in the falling position, the sliding member abuts against the first bearing surface, thereby maintaining the relative stability between the sliding member and the lifting part, reducing the relative movement between the cleaning component and the second bracket, and ensuring the cleaning effect of the cleaning component.

[0024] The second bearing surface is a surface parallel to the horizontal direction. The second bearing surface is located at the top of the lifting surface. When the cleaning component is in the raised position, the sliding member abuts against the second bearing surface, thereby maintaining the relative stability between the sliding member and the lifting part, so that the sliding member can be kept in the raised position.

[0025] The bottom of the lifting unit is provided with a mounting groove that runs vertically through the lifting unit, allowing the swing arm to be inserted downward into the first notch. This allows the sliding component to move relative to the lifting unit, and the cleaning component to move between the falling position and the rising position. Alternatively, the swing arm can protrude upward from the lifting unit, thereby restricting the relative movement between the sliding component and the lifting unit. This keeps the cleaning component in the falling position, thus improving the situation where the cleaning component loses downward pressure when it is in the outward expansion state, ensuring the contact state between the cleaning component and the surface to be cleaned, and ensuring the cleaning effect of the cleaning component on the surface to be cleaned.

[0026] In an exemplary embodiment of this application, the swing arm includes a swing rod and a protrusion. The swing rod is rotatably connected to the mounting groove; the protrusion is disposed at the end of the swing rod, and when the protrusion abuts against the support plate, it protrudes beyond the lifting surface and / or the first bearing surface; when the protrusion is inserted into the first notch, the protrusion does not extend beyond the lifting surface and the first bearing surface.

[0027] The swing arm facilitates installation of the swing arm and the mounting groove. Simultaneously, the rotation of the swing arm increases the swing amplitude of the protrusion at its end, ensuring the swing distance of the swing arm. When the protrusion presses against the support plate, it can protrude beyond the lifting surface and / or the first bearing surface. When the protrusion is inserted into the first notch, it does not extend beyond the lifting surface and the first bearing surface, thus ensuring the functionality of the swing arm.

[0028] In an exemplary embodiment of this application, the second bracket includes a limiting portion. The limiting portion is located above the first bearing surface to restrict the sliding member from moving vertically upward relative to the second bracket when the sliding member is located on the first bearing surface; when the rocker arm presses against the support plate, the gap between the rocker arm and the limiting portion is less than the minimum distance for the sliding member to pass through.

[0029] When the cleaning component is in the falling position and cleaning the surface to be cleaned, the cleaning component is subjected to an upward reaction force from the surface to be cleaned. The limiting part can restrict the upward movement of the cleaning component, so that the cleaning component fits the surface to be cleaned and ensures the cleaning effect of the cleaning component.

[0030] When the swing arm is pressed against the support plate, the gap between the swing arm and the limiting component is small, thereby preventing the relative movement of the sliding part and the lifting part, thus limiting the relative movement of the cleaning component and the second bracket, keeping the cleaning component in the falling position, ensuring the downward pressure of the cleaning component on the surface to be cleaned, thereby ensuring contact with the surface to be cleaned and ensuring the cleaning effect.

[0031] In an exemplary embodiment of this application, the first bracket includes a second notch having a first end and a second end; the second bracket includes a third notch having a third end and a fourth end, the direction from the third end to the fourth end being the same as the direction from the first end to the second end; the cleaning component includes a connecting portion, a sliding member being disposed at the end of the connecting portion away from the cleaning component, the end of the connecting portion where the sliding member is disposed passing through the second notch and the third notch, so that the sliding member abuts against the lifting portion; wherein, when the second bracket is in the retracted position, the connecting portion abuts against the first end, and when the second bracket moves from the retracted position to the receiving position, the relative movement of the sliding member and the lifting portion causes the cleaning component to move from the falling position to the lifting position.

[0032] After the connecting part passes through the second and third notches in sequence, the sliding part presses against the lifting part. When the second bracket is in the retracted position, the connecting part is located at the first end. The second notch limits the connecting part, so that when the second bracket moves from the retracted position to the receiving position, the connecting part cannot move horizontally synchronously with the second bracket. Through the cooperation of the sliding part and the lifting part, the horizontal movement of the lifting part drives the vertical movement of the sliding part, thereby causing the cleaning component to move from the falling position to the lifting position. This realizes that the drive mechanism drives the second bracket to move horizontally and drives the cleaning component to move vertically, ensuring the switching between the falling and lifting positions of the cleaning component.

[0033] When the second support moves between the inward and outward positions, the connecting part can move along the second notch. The cleaning component moves synchronously with the second support under the combined action of gravity and the lifting part. The cleaning component can switch between the normal state and the outward state to clean the surface to be cleaned according to the actual situation, reduce cleaning blind spots, and improve the cleaning effect.

[0034] In an exemplary embodiment of this application, when the second bracket is in the retracted position, the swing arm presses against the support plate at the edge of the first notch. In response to the second bracket moving from the retracted position to the receiving position, the swing arm is driven by the driving member to insert into the first notch.

[0035] When the second bracket is in the retracted position, the swing arm presses against the edge of the first notch, so that when the second bracket moves from the retracted position to the receiving position, the first notch is exposed, allowing the swing arm to be inserted into the first notch and ensuring the function of the swing arm.

[0036] When the second bracket moves from the retracted position to the receiving position, the swing arm and the slider restrict each other. When the second bracket is in the retracted position, the swing arm presses against the edge of the first notch. When the second bracket moves a short distance from the retracted position to the receiving position, the swing arm can be inserted into the first notch. This allows the slider to have a small amount of movement margin on the lifting surface or the first bearing surface when the swing arm restricts the movement of the slider. This reduces the range of motion between the cleaning component and the second bracket when the swing arm restricts the movement of the slider, thereby reducing the shaking of the cleaning component and ensuring the cleaning effect of the cleaning component on the surface to be cleaned.

[0037] In an exemplary embodiment of this application, a driving member applies a force to the swing arm, causing the swing arm to have a tendency to move from a restricted position to an open position; wherein, in response to the second bracket moving from a receiving position to an outward position relative to the first bracket, the end of the swing arm moves along a guide surface of the first bracket or the device body, and the guide surface restricts the movement of the swing arm from the restricted position to the open position at least when the second bracket is in the outward position relative to the first bracket.

[0038] The guide surface can be set on the first bracket or on the main body of the device. When the second bracket is in the outward expansion position relative to the first bracket, the guide surface restricts the movement of the swing arm from the restricted position to the open position, so that the swing arm is kept in the restricted position, thereby keeping the cleaning component in the falling position. This improves the situation where the cleaning component is prone to losing downward pressure when in the outward expansion state, effectively ensuring the adhesion between the cleaning component and the surface to be cleaned, and ensuring the cleaning effect of the cleaning component on the surface to be cleaned.

[0039] The guide surface can also restrict the movement of the swing arm from the restricted position to the open position when the second bracket is in other positions relative to the first bracket. For example, when the guide surface is in a position between the outward expansion position and the inward contraction position relative to the first bracket, the swing arm restricts the movement of the swing arm from the restricted position to the open position, so that the cleaning component remains in the falling state when it expands outward synchronously with the second bracket.

[0040] When the second bracket moves toward the receiving position relative to the first bracket, the drive causes the swing arm to move from the restricted position to the open position, causing the swing arm to disengage from the slider and move along the motion path of the lifting surface relative to the lifting part, so that the cleaning component can move between the falling position and the lifting position.

[0041] The lever can move along the guide surface in response to the entire movement of the second bracket relative to the first bracket from the receiving position to the outward position. The lever can also move along the guide surface in response to a partial movement of the second bracket relative to the first bracket from the receiving position to the outward position. For example, the lever moves along the guide surface when the second bracket moves from the receiving position to the inward position relative to the first bracket; the lever moves along the guide surface when the second bracket moves from the inward position to the outward position relative to the first bracket; or the lever moves along the guide surface for any segment between the receiving position and the outward position of the second bracket relative to the first bracket.

[0042] In an exemplary embodiment of this application, the drive element includes a torsion spring, one end of which abuts against a second bracket and the other end against a rocker arm. The torsion spring applies a force to the rocker arm that tends to move from a restricted position to an open position. The guide surface includes at least an inclined section, and in response to the second bracket moving from an outwardly expanding position to a retractable position relative to the first bracket, the end of the rocker arm moves along the inclined section, causing the rocker arm to move from a restricted position to an open position.

[0043] The torsion spring drives the rocker arm to move away from the second bracket. When the second bracket moves from the outward expansion position to the retracted position relative to the first bracket, the gap between the guide surface and the second bracket where the rocker arm is located gradually increases. The rocker arm can then rotate along the guide surface away from the second bracket. This ensures that as the second bracket moves from the outward expansion position to the retracted position relative to the first bracket, the rocker arm can disengage from the sliding member and move along the relative movement path of the lifting surface and the lifting part. This allows the sliding member and the lifting part to move relative to each other, thereby enabling the cleaning component to move between the falling position and the lifting position.

[0044] A second aspect of this application provides a cleaning device, which includes a device body and a cleaning module as described above. The cleaning module is installed on the device body.

[0045] The cleaning module of the cleaning equipment in this application includes a locking mechanism. When the second support is in the outward expansion position, the locking mechanism restricts the sliding of the cleaning component relative to the second support, thereby preventing the cleaning component from moving from the falling position to the rising position due to relative sliding with the second support. The cleaning component remains in the falling position under the weight of the equipment body, possessing sufficient downward pressure to ensure full contact with the surface to be cleaned, thus guaranteeing the cleaning effect and mitigating the problem of the cleaning component losing downward pressure in the outward expansion state, thereby ensuring the cleaning effect of the cleaning equipment.

[0046] In combination with existing technologies, the beneficial effects of this application are as follows:

[0047] In existing cleaning equipment, the cleaning module easily loses downward pressure when in the expanded state, resulting in poor cleaning performance. The cleaning module of this application includes a first bracket and a second bracket. A drive mechanism drives the second bracket to move relative to the first bracket. This allows for switching between the expanded and normal states of the cleaning module (the normal state refers to the cleaning module being retracted within the main body of the equipment). Furthermore, in conjunction with a lifting mechanism, it allows for switching between a lowered and raised position of the cleaning module. A single drive mechanism enables both horizontal and vertical movement of the cleaning module, reducing the number of drive mechanisms required and lowering drive costs.

[0048] The cleaning module of this application includes a locking mechanism. When the second support is in the extended position, the locking mechanism restricts the sliding of the cleaning component relative to the second support, thereby preventing the cleaning component from moving from the falling position to the rising position due to relative sliding with the second support. The cleaning component remains in the falling position under the weight of the device body, possessing sufficient downward pressure to ensure full contact with the surface to be cleaned, guaranteeing the cleaning effect and improving the problem of the cleaning component losing downward pressure in the extended state.

[0067] The following specific examples illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0068] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. The drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0069] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present application. However, it will be apparent to those skilled in the art that embodiments of the present application may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present application.

[0070] It should be noted that the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity of description and are not intended to limit the scope of this application. Any changes or adjustments to their relative relationships, without substantially altering the technical content, shall also be considered as part of the scope of this application.

[0071] Please see Figures 1 to 9 This application provides a cleaning module and cleaning equipment. The locking mechanism 600 restricts the sliding of the cleaning component 400 relative to the second bracket 200 at least in the outward expansion position, thereby keeping the cleaning component 400 in the falling position and ensuring the downward pressure of the cleaning component 400 on the surface to be cleaned when in the outward expansion state, thus effectively ensuring the cleaning effect of the cleaning component 400.

[0072] The cleaning equipment described in this application can be a self-propelled cleaning robot or a handheld floor scrubber. The self-propelled cleaning robot can be a mopping robot or a combined sweeping and mopping robot, etc.

[0073] For example, the cleaning equipment has a main body, the interior of which can accommodate various components of the cleaning equipment. The shape of the main body can be any shape, such as cylindrical, elliptical, or D-shaped, etc.

[0074] For example, self-moving cleaning equipment also includes a walking system conventionally provided on existing cleaning equipment, used to drive the machine body to move independently on the surface to be cleaned. The walking system includes at least a driver and drive wheels, which rotate under the action of the driver. There are generally two drive wheels, symmetrically arranged at the bottom of the equipment body. The specific structure of the walking system and the connection structure between the walking system and the equipment body can be found in the relevant structural descriptions of existing cleaning equipment, and will not be repeated here.

[0075] To perform its cleaning function, the cleaning equipment includes at least a cleaning component 400. The cleaning component 400 is detachably connected to the main body of the equipment, and the detachable connection method can be a snap-fit ​​connection, a bolt-fit connection, or the like. The cleaning component 400 can be configured for dry mopping or wet mopping. Optionally, in one embodiment, the cleaning component 400 is configured for wet mopping.

[0076] Optionally, the cleaning equipment may also include side brushes and roller brushes, which are located at the bottom of the main body of the equipment. Along the travel direction of the main body, both the side brushes and roller brushes are positioned in front of the cleaning assembly 400. The side brushes may be located at the edge of the main body and can rotate via a rotating mechanism, such as a motor, a combination of a motor and a reducer. When the side brushes rotate, they can gather debris from the edge of the main body towards the inside of the main body, thereby increasing the cleaning range of the cleaning equipment. The side brushes can be rubber strips or bristles, as long as they can clean the ground; there are no restrictions. The roller brushes are rotatably mounted in a roller brush cavity at the bottom of the main body. During rotation, the roller brushes can sweep away debris on the ground. The number of roller brushes can be set according to specific requirements; this embodiment does not limit the number.

[0077] Along the direction of travel of the main body of the equipment, the side brush and roller brush are positioned in front of the cleaning component 400. This facilitates the cleaning operation of dry sweeping followed by wet mopping, and also facilitates the layout of the internal space of the main body of the equipment.

[0078] In addition to the above, the cleaning equipment may also include a sensing system and a control system. The sensing system and the control system are electrically connected. The sensing system includes an LDS located on top of the equipment body, a buffer and vision sensor located at the front of the equipment body, and an edge sensor located on the front side wall of the equipment body. Among them, the LDS, buffer, and edge sensor can all measure or sense distance to obtain the distance between the edge of the equipment body and obstacles. The control system uses this distance to control the cleaning equipment to perform corresponding actions. For example, controlling the cleaning equipment to perform obstacle avoidance, edge cleaning, and returning to the base station.

[0079] The cleaning assembly 400 can be implemented in various ways. Optionally, in one embodiment, the cleaning assembly 400 includes a cleaning element 420 and a cleaning bracket 410.

[0080] The cleaning component 420 can be made of materials such as fiber cloth, sponge, or rubber, and is wound around the cleaning bracket 410. The winding shape of the cleaning component 420 on the cleaning bracket 410 can be planar, ring-shaped, or other shapes. For example, in some embodiments, the cleaning component 420 is wound around the cleaning bracket 410 in a shape similar to a ring track to form a track-like structure.

[0081] Please see Figures 1 to 9The cleaning module of this application is fixedly or detachably installed on the main body of the cleaning equipment. The cleaning module includes a first bracket 100, a second bracket 200, a drive mechanism 300, a cleaning component 400, a lifting structure 500, and a locking mechanism 600. The first bracket 100 is configured to be connected to the main body of the cleaning equipment; the second bracket 200 is slidably installed in the second bracket 100 in the horizontal direction, and the second bracket 200 has an outward expansion position, an inward retraction position, and a receiving position relative to the first bracket 100. The drive mechanism 300 drives the second support 200 to move relative to the first support 100; the cleaning component 400 is movably mounted on the second support 200; the lifting structure 500 is disposed on the cleaning component 400 and / or the second support 200, such that when the second support 200 moves relative to the first support 100 between the retracted position and the receiving position, it drives the cleaning component 400 to move between the falling position and the lifting position; the locking mechanism 600 is disposed on the second support 200, and at least when the second support 200 is in the outward expansion position, the locking mechanism 600 restricts the sliding of the cleaning component 400 relative to the second support 200, so as to keep the cleaning component 400 in the falling position.

[0082] The cleaning module of this application includes a first bracket 100 and a second bracket 200. The second bracket 200 is slidably mounted on the first bracket 100 in a horizontal direction. The second bracket 200 has an outward expansion position, an inward retraction position, and a receiving position relative to the first bracket 100. The outward expansion position is the position where the second bracket 200 drives the cleaning component 400 so that the cleaning component 400 extends out of the device body. The inward retraction position refers to the relative position of the second bracket 200 and the first bracket 100 when both the second bracket 200 and the cleaning component 400 are retracted into the device body and the cleaning component 400 is in the lowered position. The receiving position refers to the relative position of the second bracket 200 and the first bracket 100 when the second bracket 200 is retracted into the device body and the cleaning component 400 is in the raised position. When the second support 200 moves between the outward expansion position and the inward retraction position, the second support 200 drives the cleaning component 400 to move synchronously. The relative position of the cleaning component 400 and the second support 200 remains unchanged, and the cleaning component 400 is always in the falling position. When the second support 200 moves between the inward retraction position and the receiving position, the cleaning component 400 moves vertically along with the horizontal movement of the second support 200. The second support 200 drives the cleaning component 400 to switch between the falling position and the lifting position. The drive mechanism 300 drives the second bracket 200 to move relative to the first bracket 100. On the one hand, it can switch the cleaning component 400 between an extended state and a normal state. The extended state refers to the cleaning component 400 extending at least partially out of the main body of the equipment, while the normal state refers to the cleaning component 400 retracting into the main body of the equipment. On the other hand, in conjunction with the lifting mechanism, it can switch the cleaning component 400 between a falling position and a raised position. The movement of the cleaning component 400 in the horizontal and vertical directions can be achieved through a single drive mechanism 300, reducing the number of drive mechanisms 300 required and lowering the drive cost.

[0083] The lifting structure 500 can be installed on the cleaning component 400, so that when the second support 200 moves horizontally, the lifting structure 500 drives the cleaning component 400 to move vertically; the lifting structure 500 can also be installed on the second support 200, so that when the second support 200 moves horizontally, the lifting structure 500 drives the cleaning component 400 to move vertically; the lifting structure 500 includes two or more parts respectively installed on the cleaning component 400 and the second support 200, so that when the second support 200 moves horizontally, the lifting structure 500 drives the cleaning component 400 to move vertically.

[0084] The cleaning module of this application includes a locking mechanism 600. When the second support 200 is in the outward expansion position, the locking mechanism 600 restricts the sliding of the cleaning component 400 relative to the second support 200, thereby preventing the cleaning component 400 from moving from the falling position to the rising position due to relative sliding with the second support 200. The cleaning component 400 remains in the falling position under the weight of the main body of the device, possessing sufficient downward pressure to ensure full contact with the surface to be cleaned, guaranteeing the cleaning effect and improving the problem of the cleaning component 400 losing downward pressure in the outward expansion state.

[0085] Please see Figure 4 In some embodiments, the lifting structure 500 includes a lifting part 510 and a sliding member 520.

[0086] The lifting part 510 is disposed on either the second bracket 200 or the cleaning component 400, and at least part of the surface of the lifting part 510 is an inclined lifting surface 511.

[0087] The lifting part 510 can be disposed on the second bracket 200 or on the cleaning component 400. At least a portion of the surface of the lifting part 510 is an inclined lifting surface 511. The sliding member 520 moves along the inclined lifting surface 511, so that when the second bracket 200 and the first bracket 100 move horizontally, the cleaning bracket 410 moves in the vertical direction.

[0088] The slider 520 is disposed on the other of the second bracket 200 and the cleaning component 400. The slider 520 abuts against the lifting part 510. When the slider 520 moves relative to the lifting part 510 along the lifting surface 511, it has horizontal and vertical components.

[0089] The sliding member 520 and the lifting part 510 are respectively disposed on the second bracket 200 and the cleaning component 400. The sliding member 520 moves relative to the lifting part 510 along the lifting surface 511, so that the second bracket 200 moves horizontally and drives the cleaning component 400 to move vertically.

[0090] Preferably, the lifting part 510 can be disposed on the second bracket 200, and the sliding member 520 can be disposed on the cleaning component 400. Along the direction of movement of the second bracket 200 from the retracted position to the receiving position, the lifting surface 511 is inclined downward, so that when the second bracket 200 moves from the retracted position to the receiving position, the sliding member 520 moves along the surface of the lifting surface 511, causing the cleaning component 400 to be lifted upward to the lifting position.

[0091] The sliding member 520 and the lifting part 510 work together to make the second bracket 200 move horizontally and drive the cleaning component 400 to move vertically. Then, the cleaning component 400 can move in both the horizontal and vertical directions through a drive mechanism 300, thereby reducing the number of drive mechanisms 300 and reducing production costs.

[0092] In some embodiments, two lifting structures 500 are provided, and the sliders 520 of the two lifting structures 500 are provided at both ends of the cleaning assembly 400.

[0093] For example, the two sliders 520 are equidistant from both ends of the cleaning component 400, so that both ends of the cleaning component 400 rise and fall synchronously, ensuring the stability of the lifting and lowering of the cleaning component 400 and the stability of the cleaning process.

[0094] In some embodiments, the locking mechanism 600 includes a rocker arm 610 and a drive member 620. The rocker arm 610 is rotatably mounted on the second bracket 200 and has a restricted position and an open position relative to the second bracket 200. When the rocker arm 610 is in the restricted position, it is within the path of relative movement between the sliding member 520 and the lifting part 510, thereby restricting the relative movement of the sliding member 520 and the lifting part 510 along the lifting surface. This keeps the cleaning component 400 in the falling position. When the cleaning component 400 is in the falling position, it can be affected by the gravity of the main body of the device, ensuring the pressure of the cleaning component 400 on the surface to be cleaned, thereby ensuring the cleaning effect on the surface to be cleaned. When the rocker arm 610 is in the open position, it is disengaged from the path of relative movement between the sliding member 520 and the lifting part 510. The sliding member 520 and the lifting part 510 can move relative to each other along the lifting surface, thereby allowing the cleaning component 400 to move relative to the second bracket 200. The cleaning component 400 can switch between the falling position and the raised position. When the cleaning component 400 is in the falling position, it cleans the surface to be cleaned. When the cleaning component 400 is in the raised position, it facilitates the cleaning equipment to cross obstacles, or prevents the cleaning component from contaminating the ground after cleaning or when the cleaning component needs to be cleaned, thus ensuring the cleaning effect.

[0095] The driving component 620 drives the swing arm 610 to rotate relative to the second bracket 200. The driving component 620 causes the swing arm 610 to move between a restricted position and an open position. Alternatively, the driving component 620, in conjunction with the first bracket 100 or the main body of the device, causes the swing arm 610 to move between a restricted position and an open position. The movement of the swing arm 610 between the restricted position and the open position enables the cleaning component 400 to be locked and unlocked. This ensures that the cleaning component 400 has stable downward pressure in the outward expansion state and that the cleaning component 400 can switch between the raised position and the lowered position, meeting the application needs of the cleaning component 400 in different scenarios and expanding the application scenarios of the main body of the device.

[0096] In some embodiments, the drive element 620 can independently realize the movement of the swing arm 610 between the restricted position and the open position. The movement of the swing arm 610 can be a unidirectional cyclic rotation or a cyclic reciprocating motion. The drive element 620 can be a motor, a combination of a motor and a reducer, a combination of a motor and a connecting rod, etc. The drive element 620 can also be a telescopic rod, with both ends of the telescopic rod rotatably connected to the second bracket 200 and the swing arm 610, respectively, to drive the swing arm 610 to reciprocate.

[0097] In some embodiments, the drive member 620 can cooperate with the first bracket 100 to move the swing arm 610 between a restricted position and an open position. For example, the drive member 620 can be a component that drives the swing arm 610 to rotate in one direction. When the second bracket 200 moves relative to the first bracket 100, the first bracket 100 applies a force to the swing arm 610, causing the swing arm 610 to rotate in the opposite direction. The drive member 620 can be an elastic element, a telescopic rod, a motor, etc.

[0098] In some embodiments, the drive member 620 can cooperate with the device body to move the swing arm 610 between a restricted position and an open position. For example, the drive member 620 can be a component that drives the swing arm 610 to rotate in one direction. When the second support 200 moves relative to the first support 100, the device body applies a force to the swing arm 610, causing the swing arm 610 to rotate in the opposite direction. The drive member 620 can be an elastic element, a telescopic rod, a motor, etc.

[0099] Please see Figures 3 to 5 In some embodiments, the first support 100 includes a support plate 110, and the second support 200 is located above the support plate 110, and the second support 200 is slidably connected to the first support 100 along the length direction of the support plate 110. A first notch 111 is provided on the support plate 110. The end of the swing rod 610 is in an open position when inserted into the first notch 111, and in a restricted position when the end of the swing rod 610 abuts against the upper surface of the support plate 110.

[0100] The drive member 620 applies a force to the rocker arm 610, causing the rocker arm 610 to have a tendency to move from the open position to the restricted position, so that when the end of the rocker arm 610 disengages from the upper surface of the support plate 110, the end of the rocker arm 610 inserts into the first notch 111.

[0101] When the end of the swing arm 610 abuts against the upper surface of the support plate 110 but is not inserted into the first notch 111, the swing arm 610 is located at the path of relative movement between the sliding member 520 and the lifting part 510, thereby restricting the relative movement of the sliding member 520 along the lifting surface 511 and the lifting part 510, and restricting the relative movement between the cleaning component 400 and the second bracket 200, so that the cleaning component 400 is kept in the falling position. When the cleaning component 400 is kept in the falling position, it can be affected by the gravity of the main body of the equipment, ensuring the pressure of the cleaning component 400 on the surface to be cleaned, thereby ensuring the cleaning effect on the surface to be cleaned.

[0102] When the second bracket 200 moves relative to the first bracket 100, allowing the swing arm 610 to be inserted into the first notch 111, the drive member 620 drives the swing arm 610 to insert into the first notch 111. This causes the swing arm 610 to disengage from the sliding member 520 along the path of relative movement between the lifting surface 511 and the lifting part 510, allowing the sliding member 520 to move relative to the lifting part 510. Consequently, the cleaning component 400 and the second bracket 200 can slide relative to each other, and the cleaning component 400 can switch between a falling position and a rising position. When the cleaning component 400 is in the falling position, it cleans the surface to be cleaned. When the cleaning component 400 is in the rising position, it facilitates the cleaning equipment to cross obstacles, or prevents the cleaning component 420 from contaminating the ground after cleaning or when cleaning is required, thus ensuring the cleaning effect.

[0103] Please see Figure 4 and Figure 7 In some embodiments, the lifting part 510 is disposed on the second bracket 200, and the lifting part 510 includes a first bearing surface 512, a second bearing surface 513 and a mounting groove 514.

[0104] The first bearing surface 512 is parallel to the horizontal direction and is located at the bottom end of the lifting surface 511. The first bearing surface 512 is parallel to the horizontal direction. When the cleaning component 400 is in the falling position, the sliding member 520 abuts against the first bearing surface 512, thereby maintaining the relative stability between the sliding member 520 and the lifting part 510, reducing the relative movement between the cleaning component 400 and the second bracket 200, and ensuring the cleaning effect of the cleaning component 400.

[0105] The second bearing surface 513 is parallel to the horizontal direction and is disposed at the top of the lifting surface 511. The second bearing surface 513 is a surface parallel to the horizontal direction. When the cleaning component 400 is in the raised position, the sliding member 520 abuts against the second bearing surface 513, thereby maintaining the relative stability between the sliding member 520 and the lifting part 510, so that the sliding member 520 can be kept in the raised position.

[0106] The mounting groove 514 is provided on the side of the lifting part 510 near the support plate 110. The mounting groove 514 extends through the lifting part 510 at least in the vertical direction, and the swing arm 610 is rotatably mounted in the mounting groove 514.

[0107] The mounting groove 514 is provided at the bottom of the lifting part 510. The mounting groove 514 extends vertically through the lifting part 510, so that the swing rod 610 can be inserted downward into the first notch 111, so that the sliding member 520 can move relative to the lifting part 510, and the cleaning member 420 can move between the falling position and the rising position. The swing rod 610 can also protrude upward from the lifting part 510, thereby restricting the relative movement between the sliding member 520 and the lifting part 510, so that the cleaning component 400 is kept in the falling position, thereby improving the situation where the cleaning component 400 loses downward pressure when it is in the outward expansion state, ensuring the fit between the cleaning component 400 and the surface to be cleaned, and ensuring the cleaning effect of the cleaning component 400 on the surface to be cleaned.

[0108] Please see Figure 9 In some embodiments, the rocker arm 610 includes a rocker arm 611 and a protrusion 612. Preferably, the protrusion 612 is integrally formed with the rocker arm 611.

[0109] The swing rod 611 is rotatably connected to the mounting groove 514. The swing rod 611 facilitates the installation of the swing rod 610 and the mounting groove 514. At the same time, when the swing rod 611 rotates, it can increase the swing amplitude of the protrusion 612 at the end of the swing rod 611 and ensure the swing distance of the swing rod 611.

[0110] For example, the swing arm 611 is rotatably connected to the mounting groove 514 via a rotating shaft.

[0111] The rotating shaft can be fixed to the swing arm 611 and rotatably connected to the mounting groove 514 to achieve the rotatable connection between the swing arm 611 and the mounting groove 514.

[0112] The rotating shaft can also be rotatably connected to the mounting groove 514 and fixedly connected to the swing rod 611, thereby realizing the rotatable connection between the swing rod 611 and the mounting groove 514.

[0113] The rotating shaft can also be rotatably connected to the mounting groove 514 and to the swing rod 611 to achieve the rotatable connection between the swing rod 611 and the mounting groove 514.

[0114] In one embodiment, the swing rod 611 is provided with a first through hole, and the two sides of the mounting groove 514 are provided with second through holes penetrating the lifting part 510. The rotating shaft connects the first through hole and the second through hole to realize the rotational connection between the swing rod 611 and the mounting groove 514.

[0115] To reduce the risk of the swing arm 611 dislodging from the mounting groove 514, the rotating shaft is interference-fitted with the first through hole or the second through hole, thereby reducing the risk of the rotating shaft dislodging from the first and second through holes, and thus reducing the risk of the swing arm 611 dislodging from the mounting groove 514.

[0116] The protrusion 612 is provided at the end of the swing arm 611. When the protrusion 612 presses against the support plate 110, it protrudes out of the lifting surface 511 and / or the first bearing surface 512. When the protrusion 612 is inserted into the first notch 111, the protrusion 612 does not exceed the lifting surface 511 and the first bearing surface 512, thereby ensuring the realization of the function of the swing arm 610.

[0117] When the protrusion 612 presses against the support plate 110, it can protrude beyond the lifting surface 511 to restrict the relative movement of the slider 520 along the lifting surface 511 and the lifting part 510. When the protrusion 612 presses against the support plate 110, it can also protrude beyond the first bearing surface 512, thereby restricting the movement of the slider 520 towards the lifting surface 511, and further restricting the relative movement of the slider 520 and the lifting part 510, thus keeping the cleaning assembly 400 in the lowered position. When the protrusion 612 presses against the support plate 110, it can partially protrude beyond the lifting surface 511 and partially protrude beyond the first bearing surface 512 to restrict the relative movement of the slider 520 and the lifting part 510, thus keeping the cleaning assembly 400 in the lowered position.

[0118] One end of the protrusion 612 near the support plate 110 extends beyond the swing rod 611, and / or the other end of the protrusion 612 away from the support plate 110 extends beyond the swing rod 611, in order to facilitate the realization of the function of the protrusion 612.

[0119] In some embodiments, one end of the protrusion 612 near the support plate 110 extends beyond the swing rod 611 to facilitate the insertion of the protrusion 612 into the first notch 111. At the same time, when the protrusion 612 presses against the support plate 110, it is easier for the other end of the protrusion 612 to protrude out of the lifting part 510 to limit the relative movement between the sliding member 520 and the lifting part 510.

[0120] In some embodiments, the drive member 620 includes a torsion spring, one end of which abuts against the second bracket 200 and the other end against the rocker arm 610, to apply a force to the rocker arm 610 as it disengages from the support plate 110, causing it to tend to insert into the first notch 111.

[0121] The torsion spring applies a force to the rocker arm 610. On one hand, it causes the rocker arm 610 to press against the support plate 110 of the second bracket 200, thus preventing the rocker arm 610 from disengaging from the path of relative movement between the sliding member 520 and the lifting part 510. On the other hand, when the second bracket 200 moves relative to the first bracket 100, causing the rocker arm 610 to disengage from the support plate 110 and be located at the first notch 111, the rocker arm 610 can be inserted into the first notch 111, thus disengaging from the path of relative movement between the sliding member 520 and the lifting part 510. This allows the sliding member 520 and the lifting part 510 to move relative to each other, thereby allowing the cleaning component 400 and the second bracket 200 to move relative to each other, enabling the cleaning component 400 to move between the falling position and the rising position. The torsion spring has the characteristics of stable force and long durability, ensuring the stable movement of the rocker arm 610 and ensuring the functioning of the locking mechanism 600.

[0122] In some embodiments, the swing arm 611 is provided with a mounting shaft and a mounting groove for the insertion of a torsion spring. The torsion spring is sleeved outside the mounting shaft and embedded in the mounting groove. The end of the torsion spring away from the mounting groove presses against the wall of the mounting groove 514, thereby allowing the torsion spring to apply a force to the swing arm 611 to rotate toward the first notch 111. This ensures that when the second bracket 200 and the first bracket 100 move relative to each other to an appropriate position, the torsion spring drives the protrusion 612 of the swing arm 610 to insert into the first notch 111. The mounting shaft and the rotation shaft can be coaxial or non-coaxial.

[0123] In one embodiment, the rotation angle of the rocker arm 610 is small, and the mounting shaft and the rotation shaft are not coaxial, so as to reduce the stroke of the torsion spring, reduce the compression of the torsion spring, and improve the service life of the torsion spring.

[0124] Please see Figure 3 and Figure 4 In some embodiments, the second support 200 includes a limiting portion 210. The limiting portion 210 is located above the first bearing surface 512 to restrict the sliding member 520 from moving vertically upward relative to the second support 200 when the sliding member 520 is located on the first bearing surface 512.

[0125] When the cleaning component 400 is in the falling position and cleaning the surface to be cleaned, the cleaning component 400 is subjected to an upward reaction force from the surface to be cleaned. The limiting part 210 can restrict the upward movement of the cleaning component 400, so that the cleaning component 400 fits the surface to be cleaned and ensures the cleaning effect of the cleaning component 400.

[0126] When the rocker arm 610 presses against the support plate 110, the gap between the rocker arm 610 and the limiting part 210 is less than the minimum distance that accommodates the sliding member 520.

[0127] When the swing arm 610 is pressed against the support plate 110, the gap between the swing arm 610 and the limiting part 210 is small, thereby preventing the relative movement of the sliding part 520 and the lifting part 510, thus limiting the relative movement of the cleaning component 400 and the second bracket 200, so that the cleaning component 400 is kept in the falling position, ensuring the downward pressure of the cleaning component 400 on the surface to be cleaned, thereby ensuring contact with the surface to be cleaned and ensuring the cleaning effect.

[0128] In some embodiments, when the second bracket 200 is in the retracted position, the swing arm 610 presses against the support plate 110 at the edge of the first notch 111. In response to the second bracket 200 moving from the retracted position to the receiving position, the swing arm 610 is driven by the drive member 620 to insert into the first notch 111.

[0129] When the second bracket 200 is in the retracted position, the swing arm 610 presses against the edge of the first notch 111, so that when the second bracket 200 moves from the retracted position to the receiving position, the first notch 111 is exposed, so that the swing arm 610 can be inserted into the first notch 111, ensuring the realization of the function of the swing arm 610.

[0130] When the second support 200 moves from the retracted position to the receiving position, the swing rod 610 and the slider 520 restrict each other. When the second support 200 is in the retracted position, the swing rod 610 presses against the edge of the first notch 111. When the second support 200 moves a short distance from the retracted position to the receiving position, the swing rod 610 can be inserted into the first notch 111. This allows the slider 520 to have a small amount of movement margin on the lifting surface 511 or the first bearing surface 512 when the swing rod 610 restricts the movement of the slider 520. This reduces the range of motion between the cleaning component 400 and the second support 200 when the swing rod 610 restricts the movement of the slider 520, thereby reducing the shaking of the cleaning component 400 and ensuring the cleaning effect of the cleaning component 400 on the surface to be cleaned.

[0131] In some embodiments, the first support 100 includes a second notch 120 having a first end 121 and a second end 122; the second support 200 includes a third notch 220 having a third end and a fourth end, the direction from the third end to the fourth end being the same as the direction from the first end 121 to the second end 122; the cleaning component 400 includes a connecting portion 411, a sliding member 520 being disposed at the end of the connecting portion 411 away from the cleaning component 420, the connecting portion 411 passing through the second notch 120 and the third notch 220, such that the sliding member 520 abuts against the lifting portion 510; wherein, when the second support 200 is in the retracted position, the connecting portion 411 abuts against the first end 121, and when the second support 200 moves from the retracted position to the receiving position, the sliding member 520 moves relative to the lifting portion 510, causing the cleaning component 400 to move from the falling position to the lifting position.

[0132] After the connecting part 411 passes through the second notch 120 and the third notch 220 in sequence, the sliding member 520 presses against the lifting part 510. When the second bracket 200 is in the retracted position, the connecting part 411 abuts against the first end 121. The second notch 120 limits the connecting part 411, so that when the second bracket 200 moves from the retracted position to the receiving position, the connecting part 411 cannot move horizontally synchronously with the second bracket 200. Through the cooperation of the sliding member 520 and the lifting part 510, the horizontal movement of the lifting part 510 drives the sliding member 520 to move vertically, thereby causing the cleaning component 400 to move from the falling position to the lifting position. This realizes that the drive mechanism 300 drives the second bracket 200 to move horizontally and drives the cleaning component 400 to move vertically, ensuring the switching between the falling position and the lifting position of the cleaning component 400.

[0133] When the second support 200 moves between the inward and outward positions, the connecting part 411 can move along the second notch 120. The cleaning component 400 moves synchronously with the second support 200 under the combined action of gravity and the lifting part 510. The cleaning component 400 can switch between the normal state and the outward state to clean the surface to be cleaned according to the actual situation, reduce blind spots, and improve the cleaning effect.

[0134] In other embodiments, the locking mechanism 600 includes a rocker arm and a drive member. The rocker arm is rotatably mounted on the second bracket 200 and has a restricted position and an open position relative to the second bracket 200. When the rocker arm is in the restricted position, it is within the path of relative movement between the slider 520 and the lifting part 510, thereby restricting the relative movement of the slider 520 along the lifting surface 511 and the lifting part 510, so that the cleaning assembly 400 is held in the falling position.

[0135] The driving component is used to drive the swing arm to rotate relative to the second bracket 200. The driving component works with the first bracket 100 or the main body of the equipment to make the swing arm move between the restricted position and the open position.

[0136] For example, the driving member applies a force to the rocker arm such that the rocker arm has a tendency to move from a restricted position to an open position; wherein, in response to the second bracket 200 moving from a receiving position to an outward position relative to the first bracket 100, the end of the rocker arm moves along a guide surface of the first bracket 100 or the device body, the guide surface restricting the rocker arm from moving from the restricted position to the open position at least when the second bracket 200 is in the outward position relative to the first bracket 100.

[0137] The guide surface can be set on the first support 100 or on the main body of the equipment. When the second support 200 is in the outward expansion position relative to the first support 100, the guide surface restricts the movement of the swing arm from the restricted position to the open position, so that the swing arm is kept in the restricted position, thereby keeping the cleaning component 400 in the falling position. This improves the situation where the cleaning component 400 is prone to losing downward pressure when in the outward expansion state, effectively ensuring the adhesion between the cleaning component 400 and the surface to be cleaned, and ensuring the cleaning effect of the cleaning component 400 on the surface to be cleaned.

[0138] The guide surface can also restrict the movement of the swing arm from the restricted position to the open position when the second bracket 200 is in other positions relative to the first bracket 100. For example, when the second bracket 200 is in a position between the outward expansion position and the inward contraction position relative to the first bracket 100, the guide surface restricts the movement of the swing arm from the restricted position to the open position, thereby ensuring that the cleaning component 400 remains in the falling state when it expands outward synchronously with the second bracket 200. On the one hand, it can be ensured that when the second bracket 200 is in the outward expansion position relative to the first bracket 100, the guide surface restricts the movement of the swing arm from the restricted position to the open position, and the cleaning component 400 remains in the falling position, maintaining downward pressure in the outward expansion state; on the other hand, when the second bracket 200 moves from the inward contraction position to the receiving position relative to the first bracket 100, the swing arm can move to the open position, allowing the cleaning component 400 to switch between the falling position and the lifting position.

[0139] When the second bracket 200 moves toward the receiving position relative to the first bracket 100, the drive causes the swing arm to move from the restricted position to the open position. The swing arm disengages from the slider 520 and moves along the movement path of the lifting surface 511 relative to the lifting part 510, so that the cleaning assembly 400 can move between the falling position and the lifting position.

[0140] The rocker arm can move along the guide surface in response to the entire movement of the second support 200 relative to the first support 100 from the receiving position to the outward position. The rocker arm can also move along the guide surface in response to a partial movement of the second support 200 relative to the first support 100 from the receiving position to the outward position. For example, the rocker arm moves along the guide surface when the second support 200 moves from the receiving position to the inward position relative to the first support 100; the rocker arm moves along the guide surface when the second support 200 moves from the inward position to the outward position relative to the first support 100; or the rocker arm moves along the guide surface for any segment between the receiving position and the outward position of the second support 200 relative to the first support 100.

[0141] It should be noted that when the swing arm moves from the receiving position to the outward position relative to the first support 100 as the second bracket 200 moves, the movement of the swing arm lags behind the movement of the sliding member 520 and the lifting surface 511. That is, the relative movement of the sliding member 520 and the lifting surface 511 first causes the cleaning component 400 to move from the raised position to the lowered position, and only then does the swing arm move to the restricted position. Similarly, when the second support 200 moves from the outward position to the receiving position relative to the first support 100, the path of the swing arm disengaging from the relative movement of the sliding member 520 and the lifting part 510 must precede the relative movement of the sliding member 520 and the lifting part 510, thereby ensuring that the sliding member 520 and the lifting part 510 can move relative to each other so that the cleaning component 400 can move between the lowered position and the raised position.

[0142] In one embodiment, the guide surface is located at the bottom of the main body of the device, and there is a gap between the guide surface and the second bracket 200. As the second bracket 200 moves from the inward position to the outward position, the gap between the guide surface and the second bracket 200 where the swing rod 610 is located gradually decreases, so the swing rod 610 can rotate along the guide surface towards the second bracket 200 until the end of the swing rod 610 moves to the movement path of the sliding member 520 and the lifting part 510 relative to each other.

[0143] In some embodiments, the drive element includes a torsion spring, one end of which abuts against the second bracket 200 and the other end against the rocker arm, the torsion spring applying a force to the rocker arm that tends to move from the restricted position to the open position.

[0144] The guide surface includes at least an inclined section, and in response to the second support 200 moving relative to the first support 100 from an outward position to a receiving position, the end of the rocker arm moves along the inclined section so that the rocker arm moves from a restricted position to an open position.

[0145] The torsion spring drives the rocker arm to move away from the second bracket 200. When the second bracket 200 moves from the inward position to the outward position relative to the first bracket 100, the gap between the guide surface and the second bracket 200 where the rocker arm is located gradually decreases. The rocker arm can then rotate along the guide surface towards the second bracket 200. This ensures that when the second bracket 200 is in the outward position, the rocker arm is located at the movement path of the slider 520 along the lifting surface 511 and the lifting part 510, thereby limiting the relative movement of the slider 520 and the lifting part 510. This keeps the cleaning component 400 in the falling position, allowing the cleaning component 400 to adhere to the surface to be cleaned, thus ensuring the cleaning effect of the cleaning component 400.

[0146] In some embodiments, the end of the lever has a protrusion extending away from the bottom of the device body to limit the relative movement of the slider and the lifting part.

[0147] A second aspect of this application provides a cleaning device, which includes a device body and a cleaning module as described above. The cleaning module is installed on the device body.

[0148] The cleaning module can be fixedly installed on the main body of the equipment or detachably installed on the main body of the equipment. Preferably, the cleaning module can be detachably installed on the main body of the equipment to facilitate the replacement and cleaning of the cleaning module.

[0149] The cleaning equipment described in this application may include a walking system, a sensing system, a control system, etc. Please refer to existing cleaning equipment; this application will not elaborate on these aspects.

[0150] The cleaning module of the cleaning equipment of this application includes a locking mechanism 600. When the second support 200 is in the outward expansion position, the locking mechanism 600 restricts the sliding of the cleaning component 400 relative to the second support 200, thereby preventing the cleaning component 400 from moving from the falling position to the rising position due to relative sliding with the second support 200. The cleaning component 400 remains in the falling position under the weight of the equipment body, possessing sufficient downward pressure to ensure full contact with the surface to be cleaned, thus guaranteeing the cleaning effect and mitigating the problem of the cleaning component 400 losing downward pressure in the outward expansion state, thereby ensuring the cleaning effect of the cleaning equipment.

[0151] Therefore, this application effectively overcomes some practical problems in the prior art and thus has high utilization value and significance.

[0152] The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
