[0001] Cross-reference of related applications

[0002] This application claims the benefit of Chinese Patent Application No. 202520132900.5, filed on January 20, 2025, the contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of cleaning equipment, specifically to a cleaning component and cleaning equipment. Background Technology

[0004] As living standards improve, the use of household cleaning equipment is becoming increasingly widespread, leading to higher demands and more sophisticated functions. For example, some cleaning equipment features liftable squeegees to improve cleaning efficiency when there is a lot of dust or hair on the floor; others have liftable roller brushes or other liftable components to meet different usage needs. However, the increase in lifting components also leads to a greater need for drive mechanisms, resulting in increased costs and inconvenient space layout. Summary of the Invention

[0005] In view of the problems existing in the prior art, this application provides a cleaning component and cleaning equipment to improve the problems of increased cost and inconvenient space layout caused by the need for multiple drive mechanisms for multiple lifting components.

[0006] To achieve the above and other related objectives, a first aspect of this application provides a cleaning component, including a housing, a first lifting member, a second lifting member, and a drive mechanism; the housing has a suction chamber, and the suction chamber has a suction port at one end facing the surface to be cleaned; the first lifting member is movably disposed in the housing, and the first lifting member has at least a first position and a second position; the second lifting member is movably disposed in the housing, and the second lifting member has at least a third position and a fourth position; the drive mechanism drives the first lifting member and the second lifting member to move; the drive mechanism includes a first linkage assembly, a second linkage assembly, and a drive unit; the first linkage assembly drives the first lifting member to move between the first position and the second position; the second linkage assembly drives the second lifting member to move between the third position and the fourth position; the drive unit drives the first linkage assembly and the second linkage assembly to move, so as to respectively drive the first lifting member and the second lifting member to move.

[0007] The drive unit can drive the first linkage assembly and the second linkage assembly to drive the first lifting component and the second lifting component to move respectively, which effectively reduces the number of drive units, reduces costs, saves space for the cleaning components, and facilitates the spatial layout of the cleaning components.

[0008] In an exemplary embodiment of this application, the first linkage assembly includes a first driving member and a first driven member, the first driving member being connected to the driving unit, and the first driven member being rotatably connected to the first driving member; the second linkage assembly includes a second driving member and a second driven member, the second driving member being fixed to the first driving member, and the second driven member being rotatably connected to the second driving member.

[0009] The first driving member is driven to rotate by the drive unit, thereby driving the first driven member to move, and thus realizing the movement of the first lifting member. The second driving member is fixed to the first driving member and rotates synchronously with the first driving member, so that the drive unit simultaneously drives the second driving member and the first driving member to rotate, and thus simultaneously drives the first lifting member and the second lifting member to move.

[0010] In an exemplary embodiment of this application, the first driving member is a rotating wheel, and a first rotating shaft is provided at the eccentric part of the first driving member. The first driven member and the first driving member are rotatably connected through the first rotating shaft.

[0011] The first driving member is a rotating wheel, which can balance the force when the first driving member drives the first driven member to rotate, thereby improving the stability of the first driving member during rotation.

[0012] In an exemplary embodiment of this application, the second active member is fixed to the first active member via the first rotating shaft; the second active member is a rotating wheel.

[0013] The second driving member is fixedly connected to the first driving member via a first rotating shaft, preventing interference between the first driven member and the second driving member when the latter rotates. This effectively ensures that the second and first driving members move synchronously and that the first driven member moves along a predetermined trajectory. The second driving member is a rotating wheel, which balances the forces acting on it during rotation, effectively improving its stability.

[0014] In an exemplary embodiment of this application, a second rotating shaft is provided at the eccentric part of the second driving member, and the second driven member is rotatably connected to the second driving member through the second rotating shaft; the angle between the second rotating shaft and the first rotating shaft about the axis of the second driving member is 45° to 135°.

[0015] The first and second lifting components need to be configured in different positional combinations as required. For example, when the first lifting component is in the first position, the second lifting component may be in the third or fourth position; when the first lifting component is in the second position, the second lifting component may be in the third or fourth position. By setting the included angle between the second and first rotating axes, different positional combinations between the first and second lifting components can be effectively ensured, thereby guaranteeing their functional effects.

[0016] In an exemplary embodiment of this application, the cleaning component includes a support wheel, which is fixed to the second active member and is rotatably mounted on the housing.

[0017] By rotating the support wheels mounted on the housing, the drive mechanism can be supported, thereby reducing the radial shear force on the drive unit, reducing the risk of damage to the drive unit, and increasing the service life of the drive unit.

[0018] In an exemplary embodiment of this application, the cleaning component includes a detection module configured to detect the rotation angle of a first active member and / or a second active member to determine the positions of a first lifting member and a second lifting member.

[0019] The second driving member rotates synchronously with the first driving member. By detecting the rotational position of either the first driven member or the second driven member, the rotational position of the other driven member can be determined, thereby obtaining the current position of the first lifting member and the second lifting member. This allows the drive unit to be controlled to move the first lifting member and the second lifting member to the desired position.

[0020] In an exemplary embodiment of this application, the detection module includes a calibration module and a determination module. The calibration module includes a calibration sensor and a calibration sensing area. One of the calibration sensor and the calibration sensing area is fixed to the housing, and the other is fixed to the first active component. The calibration module is triggered when the calibration sensing area coincides with the calibration sensor. The determination module includes a determination sensor and at least two determination sensing areas. One of the determination sensor and the determination sensing area is fixed to the housing, and the other is fixed to the first active component. The determination module is triggered when the determination sensing area coincides with the determination sensor.

[0021] When the first active component rotates to a calibrated angle, the calibration module is triggered, at which point the first and second lifting components have a first position state combination. When the first active component continues to rotate to a second preset angle, the determination sensor is triggered once, at which point the first and second lifting components have a second position state combination. When the first active component continues to rotate to a third preset angle, the determination sensor is triggered twice, at which point the first and second lifting components have a third position state combination. By triggering the calibration module and the determination module respectively, the position state combination of the first and second lifting components can be obtained, thereby realizing the control of the positions of the first and second lifting components and effectively ensuring the functional realization of the first and second lifting components.

[0022] In an exemplary embodiment of this application, the detection module has at least three trigger positions within one rotation cycle of the first active member and / or the second active member.

[0023] Within one rotation cycle of the first active component, there are at least three trigger positions. The three trigger positions correspond to different position state combinations of the first and second lifting components, thereby realizing the control of the positions of the first and second lifting components, so that the first and second lifting components can stay at the expected positions.

[0024] In an exemplary embodiment of this application, the detection module includes a detector and a detection element, one of which is fixed relative to the first active element and the other is fixed relative to the housing. The detection element triggers the detector at least three times within one rotation cycle of the first active element.

[0025] One of the detection elements or detectors rotates synchronously with the first active element, while the other is fixed relative to the housing. When the first active element rotates to a preset position, the detection element triggers the detector, thereby monitoring the rotation angle of the first active element. When the first active element rotates to the expected position, the control drive unit stops the first active element, causing the first lifting element and the second lifting element to stop at the expected position.

[0026] In an exemplary embodiment of this application, the detection element includes a first detection element and a second detection element; the first detection element is fixed relative to the first active element, and the first detection element has at least one first detection area; the second detection element is fixed relative to the first active element, and the second detection element has at least one second detection area; the detector includes a first detector and a second detector; the first detector is fixed relative to the housing, and the first detector is triggered when the first detection area rotates to the first detector; the second detector is fixed relative to the housing, and the second detector is triggered when the second detection area rotates to the second detector.

[0027] By setting a first detector and a second detector, on the one hand, the rotation angle of the first active member can be calibrated by triggering the first detector and / or the second detector, and on the other hand, the preset rotation angle of the first active member can be determined, thereby determining the position of the first lifting member and the second lifting member based on the rotation angle of the first active member, and then controlling the start and stop of the drive unit.

[0028] In an exemplary embodiment of this application, one first detection area is provided, and two second detection areas are provided. The first detection area and the second detection area do not trigger the first detector and the second detector simultaneously.

[0029] When the first detector in the first detection zone is triggered, the second detector in the second detection zone will not be triggered. When the first detector is triggered, it indicates that the first and second lifting components are in a first position state combination. Then, as the drive unit continues to operate, the number of times the second detector in the second detection zone is triggered determines the rotation angle of the first active component when the second detector is triggered, thus determining the current position state combination of the first and second lifting components. When the cleaning component starts operating but cannot determine the current position state combination of the first and second lifting components, it first drives the first active component to rotate to the first detector trigger angle via the drive unit, and then controls the drive unit to rotate the first active component to the expected angle according to actual needs, causing the first and second lifting components to move to the expected positions.

[0030] In an exemplary embodiment of this application, the first detection area and the second detection area do not coincide in the direction of the rotation axis of the first active member.

[0031] The positions of the first detection area and the second detection area do not overlap, ensuring that the first detector and the second detector are not triggered at the same time, thereby enabling the determination of different rotation angles of the first active component.

[0032] In an exemplary embodiment of this application, two first detection areas and two second detection areas are provided. In one case, the first detection area and the second detection area trigger the first detector and the second detector simultaneously, respectively. In the other case, the first detection area and the second detection area do not trigger the first detector and the second detector simultaneously.

[0033] When the first detector and the second detector are triggered simultaneously, the rotation angle of the first active component can be determined. When the first detector and the second detector are triggered separately, the other two rotation angles of the first active component can be determined. Thus, based on the cooperation of the first detector and the second detector, the three rotation angles of the first active component can be determined, obtaining three different combinations of the position states of the first lifting component and the second lifting component, which facilitates the control of the positions of the first lifting component and the second lifting component.

[0034] In an exemplary embodiment of this application, the first detection element and the second detection element are disc-type detection elements, the first detection area and the second detection area are through detection holes on the disc-type detection element, and the first detector and the second detector are optical coupler detectors.

[0035] When the disc-type detector rotates, the force on the drive unit is more even, reducing radial shear force on the drive unit and extending its service life. The through-hole and optical coupler detector facilitate detector triggering, making it easier to implement and less costly.

[0036] In an exemplary embodiment of this application, the cleaning component includes a support wheel fixed to the second active member, the support wheel being rotatably disposed on the housing; a connecting shaft is fixedly disposed at the axle of the support wheel; wherein, the first detection member is fixedly disposed on the connecting shaft so that the first detection member is relatively fixed to the first active member; the second detection member is fixedly disposed on the connecting shaft on the side of the first detection member away from the support wheel.

[0037] The support wheel supports the drive mechanism, reducing the stress on the drive unit and lowering the risk of damage. The first and second detection components are positioned on the side of the support wheel furthest from the drive unit, thus avoiding the problem of the drive mechanism being easily damaged due to its larger span. Simultaneously, the support wheel also provides support for the first and second detection components, improving their operational stability.

[0038] In an exemplary embodiment of this application, the cleaning component includes a rotary bearing, which is fixedly mounted on the housing, and the connecting shaft is fixed to the inner ring of the rotary bearing; the rotary bearing is disposed on the side of the second detection element away from the first detection element.

[0039] The support wheels and rotating bearings are located on both sides of the detection module, providing support to both ends of the detection module, improving the stability of the detection module during rotation, and improving the accuracy of the detection.

[0040] In an exemplary embodiment of this application, with the forward direction of the cleaning device as the front side, the second lifting member in the fourth position is located behind the suction port and abuts against the surface being cleaned.

[0041] The second lifting component is located behind the suction port and abuts against the surface being cleaned. It can scrape away dust, debris, etc. that have not yet been cleaned, reducing the situation where dust and debris remain on the surface being cleaned after the cleaning components move, and improving the cleaning ability of the cleaning components.

[0042] In an exemplary embodiment of this application, in the fourth position, the second linkage assembly applies a force to the second lifting member, causing the second lifting member to press against the surface being cleaned.

[0043] The second lifting component presses against the surface being cleaned, meaning that the second lifting component is in contact with the surface being cleaned and there is pressure, so that the second lifting component is in close contact with the surface being cleaned, so as to effectively clean the surface being cleaned.

[0044] In an exemplary embodiment of this application, the part where the second lifting member abuts against the surface being cleaned is a flexible part, and the second lifting member at the fourth position has a first interference fit with the surface being cleaned.

[0045] The second lifting component has a first interference fit with the surface to be cleaned, and the part that contacts the surface to be cleaned is a flexible part, so that the second lifting component is close to the surface to be cleaned, which improves the ability of the second lifting component to scrape dust and debris, and effectively improves the cleaning effect of the second lifting component.

[0046] In an exemplary embodiment of this application, when the second lifting member is in the fourth position, the flexible part is perpendicular to the surface being cleaned from top to bottom, or the flexible part is tilted from top to bottom in the opposite direction of the direction of movement of the cleaning device.

[0047] The flexible part is perpendicular to the surface being cleaned or tilted in the opposite direction of the cleaning equipment's forward movement. This facilitates relative movement between the flexible part and the surface being cleaned as the cleaning equipment moves forward. This effectively protects the second lifting component, slows down its wear, and extends its service life. At the same time, it reduces the forward resistance of the cleaning equipment, thus saving energy and reducing consumption.

[0048] In an exemplary embodiment of this application, a second cover plate is provided on the rear side of the housing, the second cover plate and the surface of the housing form a second limiting groove, and the second lifting member moves along the second limiting groove.

[0049] On the one hand, the second cover plate protects the second lifting component from damage; on the other hand, the second limiting groove formed between the second cover plate and the housing restricts the movement path of the second lifting component, allowing it to move along a predetermined trajectory between the third and fourth positions. For example, the second lifting component can move along the surface of the housing to avoid interference with other components during its movement. Furthermore, the addition of the second lifting component requires minimal alteration to the original structure of the cleaning assembly, facilitating its structural design.

[0050] In an exemplary embodiment of this application, the rear side of the housing is provided with a mounting portion extending away from the suction chamber, and the mounting portion is provided with a through hole; the second lifting member includes: an upper lifting portion disposed on the upper side of the mounting portion and rotatably connected to the second connecting rod assembly; a lower lifting portion disposed on the lower side of the mounting portion; and a reset member connected to the lower lifting portion to apply a force to the lower lifting portion toward the mounting portion; wherein the upper lifting portion and / or the lower lifting portion are provided with an abutment portion penetrating the through hole, so that the upper lifting portion abuts against the lower lifting portion, and when the second lifting member moves to the fourth position, the upper lifting portion drives the lower lifting portion to move.

[0051] Due to structural limitations, existing housings typically have a mounting portion extending away from the suction chamber, meaning the mounting portion extends outward from the cleaning component. If the second lifting member is directly positioned on the side of the mounting portion away from the suction chamber, it increases the volume of the cleaning component, resulting in an excessively large cleaning device and limiting its application scenarios. The second lifting member of this application includes an upper lifting portion and a lower lifting portion, respectively positioned on the upper and lower sides of the mounting portion. Utilizing the space above and below the mounting portion to install the second lifting member effectively reduces its impact on the volume of the cleaning component. When the second lifting member moves to the fourth position, the upper and lower lifting portions press against each other to move the lower lifting portion; when the second lifting member moves to the third position, the upper lifting portion is driven by the first connecting rod assembly, and the lower lifting portion is driven by the reset member, thus moving the second lifting member to the third position.

[0052] In an exemplary embodiment of this application, the rear side of the housing is provided with a mounting portion extending away from the suction chamber, and the mounting portion is provided with a through hole; the second lifting member includes: an upper lifting portion disposed on the upper side of the mounting portion and rotatably connected to the second connecting rod assembly; and a lower lifting portion disposed on the lower side of the mounting portion; wherein the upper lifting portion and / or the lower lifting portion are provided with a connecting portion through the through hole, so that the upper lifting portion and the lower lifting portion are fixedly connected.

[0053] The upper and lower lifting parts are fixed relative to each other after passing through the through hole, which not only effectively realizes the synchronous movement of the upper and lower lifting parts, but also avoids the problem of the cleaning component being too large due to the second lifting part being set on the side of the installation part far away from the suction chamber, thus improving the integration of the cleaning component.

[0054] In an exemplary embodiment of this application, a first cover plate is provided on the front side of the housing, the first cover plate and the surface of the housing form a first limiting groove, the first lifting member is at least partially disposed in the first limiting groove, and the first lifting member moves along the first limiting groove.

[0055] On the one hand, the first cover plate protects the first lifting component and reduces the risk of the first lifting component being damaged by collision; on the other hand, a first limiting groove is formed between the first cover plate and the housing to accommodate the sliding of the first lifting component, so that the first lifting component moves between the first position and the second position along a predetermined trajectory, avoiding interference with other components during the movement of the first lifting component.

[0056] In an exemplary embodiment of this application, when the first lifting member is in the second position, it covers part of the front side of the suction port, so that the ventilation area of ​​the front side of the suction port is smaller than the ventilation area of ​​the first lifting member when it is in the first position.

[0057] When the first lifting component is in the second position, the ventilation area in front of the suction port is reduced. While the suction force remains unchanged, the air velocity and pressure of the suction port are increased, which effectively improves the adsorption capacity for dust, hair, etc., and meets the usage needs of the cleaning components in different scenarios.

[0058] A second aspect of this application provides a cleaning device, including a device body and a cleaning component as described in any of the preceding claims, the cleaning component being mounted on the device body.

[0059] The cleaning assembly drives two linkage assemblies through a drive unit, which in turn drives the first and second lifting components to move, reducing the number of drive units required for the cleaning equipment and lowering the cost and weight of the cleaning equipment.

[0060] In combination with existing technologies, the beneficial effects of this application are as follows:

[0061] Existing cleaning components require an additional drive mechanism for each additional lifting component, leading to increased costs and inconvenient space layout. The cleaning component of this application uses a single drive unit to drive a first and second linkage assembly, thereby moving the first lifting component between a first and second position, and the second lifting component between a third and fourth position. By using a single drive unit and two linkage assemblies to move both lifting components, the number of drive units is effectively reduced, costs are lowered, and the space layout of the cleaning component is simplified.

[0074] 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, and 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. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other. It should also be understood that the terminology used in the embodiments of this application is for describing specific implementation schemes and not for limiting the scope of protection of this application. Test methods in the following embodiments that do not specify specific conditions are generally performed under conventional conditions or according to the conditions recommended by the respective manufacturers.

[0075] When numerical ranges are given in the embodiments, it should be understood that, unless otherwise stated in this application, both endpoints of each numerical range and any value between the two endpoints may be selected. Unless otherwise defined, all technical and scientific terms used in this application, as well as the prior art known to those skilled in the art and the descriptions in this application, may be implemented using any prior art methods, devices, and materials similar to or equivalent to the methods, devices, and materials in the embodiments of this application.

[0076] 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.

[0077] The cleaning components of the cleaning equipment may include a negative pressure mechanism, which includes a suction chamber and a negative pressure fan. The suction chamber is connected to the surface to be cleaned and the negative pressure fan. The negative pressure fan creates negative pressure in the suction chamber to suck up dust, particles, and other dirt from the surface to be cleaned. The negative pressure mechanism may include a housing, which may form the suction chamber. One end of the housing facing the surface to be cleaned has a suction port, and the other end has a dust outlet that connects to a dust collection duct. The dust collection duct can connect to the dust inlet of the dust box, and the dust collection duct of the dust box can connect to the negative pressure fan. The negative pressure fan can generate negative pressure in the suction chamber to suck up dust, large particles (such as cat litter), and other dirt from the surface to be cleaned. The airflow carrying the dirt passes through the suction port and dust outlet of the housing, the dust collection duct, the dust box, and the negative pressure fan, and is discharged through the outlet of the negative pressure fan, leaving the dirt in the dust box.

[0078] The cleaning components of the cleaning equipment may also include a roller brush module, which may include a roller brush drive and a roller brush. The roller brush may be set in the suction chamber, and the roller brush drive may be set on the surface of the housing away from the suction chamber. The roller brush drive may drive the roller brush to rotate, so as to further move the dirt on the cleaning surface in the suction chamber, and then use negative pressure to suck the dirt into the dust box, thereby improving the cleaning effect of the cleaning components on dust, particulate matter and other dirt on the cleaning surface.

[0079] With the widespread use of cleaning equipment, functional requirements are also increasing. For example, some cleaning equipment adds a rear scraper to reduce the escape of dust and particles from the suction chamber, improving cleanliness. The rear scraper usually needs to move up and down to meet the needs of different scenarios. Some cleaning equipment adds a movable baffle to change the air intake area of ​​the suction chamber, thereby changing the suction power to meet the needs of cleaning different surfaces such as floors and carpets. The rear scraper, baffle, etc., added to existing cleaning equipment all require an independent drive device to meet the movement needs of the moving parts, resulting in problems such as too many drive devices, increased costs, and inconvenient space layout.

[0080] In view of this, this application provides a cleaning component and cleaning equipment, which includes a drive mechanism 400. The drive mechanism 400 drives the first linkage assembly 410 and the second linkage assembly 420 to move via a drive unit 430, thereby driving the first lifting member 200 and the second lifting member 300 to move. By using one drive unit 430 to move multiple lifting members, the number of drive units 430 is effectively reduced, costs are lowered, and space layout is facilitated. The cleaning component of this application can also add linkage assemblies according to actual needs, so that multiple components can be moved via one drive unit 430, thereby simplifying the drive design of moving parts, reducing the number of drive units 430, and lowering costs.

[0081] Please refer to Figures 1 to 11. A first aspect of this application provides a cleaning assembly, including a housing 100, a first lifting member 200, a second lifting member 300, and a drive mechanism 400. A suction chamber 140 is formed within the housing 100. A suction port 141 is provided at one end of the suction chamber 140 facing the surface to be cleaned. The suction port 141 draws dust, particles, and other contaminants from the surface to be cleaned into the suction chamber 140. A first lifting member 200 is movably disposed on the housing 100, and the first lifting member 200 has at least a first position and a second position; a second lifting member 300 is movably disposed on the housing 100, and the second lifting member 300 has at least a third position and a fourth position; a driving mechanism 400 drives the first lifting member 200 and the second lifting member 300 to move; the driving mechanism 400 includes a first link assembly 410, a second link assembly 420 and a driving part 430; the first link assembly 410 drives the first lifting member 200 to move between the first position and the second position; the second link assembly 420 drives the second lifting member 300 to move between the third position and the fourth position; the driving part 430 drives the first link assembly 410 and the second link assembly 420 to move, so as to drive the first lifting member 200 and the second lifting member 300 to move respectively.

[0082] By using a single drive unit 430 to drive the first linkage assembly 410 and the second linkage assembly 420 to move the first lifting member 200 and the second lifting member 300 respectively, the number of drive units 430 is effectively reduced, costs are lowered, space is saved for the cleaning assembly, and the spatial layout of the cleaning assembly is facilitated. At the same time, the number of linkage assemblies can be increased according to actual needs, so that one drive unit 430 can drive multiple linkage assemblies to move multiple lifting members, simplifying the design process.

[0083] The first lifting member 200 and the second lifting member 300 are components that have relative movement with the housing 100. For example, the lifting member can be a baffle provided at the front of the housing 100 to block part of the air intake channel of the suction port 141; the lifting member can also be a scraper provided at the rear of the housing 100 to scrape dust and particles on the surface to be cleaned; the lifting member can also be a scraper for scraping dirt off the surface of the roller brush module 600, etc.

[0084] Of course, as some possible approaches, the first lifting component 200 and the second lifting component 300 can also be other components that have relative movement with the housing 100, in order to realize different functions of the cleaning components and expand the application scenarios of the cleaning equipment.

[0085] The first lifting member 200 is movably disposed on the housing 100. The relative movement between the first lifting member 200 and the housing 100 can be relative movement, for example, the first lifting member 200 is a baffle for blocking part of the air intake passage at the front of the suction port 141, and the baffle moves along the surface of the housing 100 between a first position and a second position; the relative movement between the first lifting member 200 and the housing 100 can be relative rotation, for example, the first lifting member 200 is a baffle for blocking part of the air intake passage at the suction port 141, and the baffle is rotatably disposed on the housing 100, and the baffle rotates around the rotation axis of the baffle between a first position and a second position; the relative movement between the first lifting member 200 and the housing 100 can also be a combination of relative movement and rotation, etc.

[0086] Similarly, the second lifting member 300 is movably disposed on the housing 100, and the relative movement between the second lifting member 300 and the housing 100 can be in the form of relative movement, relative rotation, or a combination of relative movement and relative rotation.

[0087] The drive unit 430 includes, but is not limited to, a motor, which drives the first linkage assembly 410 and the second linkage assembly 420 to move along a predetermined trajectory. Preferably, the drive unit 430 is a motor. The output shaft of the motor can be directly connected to the first linkage assembly 410 and / or the second linkage assembly 420, or the output shaft of the motor can be connected to a gearbox, and the output shaft of the gearbox is connected to the first linkage assembly 410 and / or the second linkage assembly 420.

[0088] Referring to Figures 4 and 7, in one embodiment, the first linkage assembly 410 includes a first driving member 411 and a first driven member 412. The first driving member 411 is connected to the drive unit 430, and the first driven member 412 is rotatably connected to the first driving member 411. The drive unit 430 drives the first driving member 411 to rotate, and the first driving member 411 drives the first driven member 412 to move, thereby driving the first lifting member 200 to move along a predetermined trajectory between a first position and a second position. The second linkage assembly 420 includes a second driving member 421 and a second driven member 422. The second driving member 421 is fixed to the first driving member 411, such that the second driving member 421 is connected to the drive unit 430. The drive unit 430 synchronously drives the first driving member 411 and the second driving member 421 to move, and the second driving member 421 drives the second driven member 422 to move, thereby driving the second lifting member 300 to move along a predetermined trajectory between a third position and a fourth position. By fixing the second active member 421 to the first active member 411, the drive unit 430 can simultaneously drive the first linkage assembly 410 and the second linkage assembly 420 to move, thereby driving the first lifting member 200 and the second lifting member 300 to move, reducing the number of drive units 430, lowering costs, and facilitating structural layout.

[0089] Please refer to Figures 7 and 8. In one embodiment, the first driving member 411 is a rotating wheel. On the one hand, when the driving unit 430 drives the first driving member 411 to rotate, the rotating wheel can balance the force on the driving unit 430, reduce the shear force on the driving unit 430, and improve the service life of the driving unit 430. On the other hand, the rotating wheel can balance the force on the first driving member 411 when it drives the first driven member 412 to rotate, play a balancing role, and improve the stability of the first driving member 411 when it rotates.

[0090] The rotating wheel can be weight-reduced according to actual needs, such as by creating hollow areas or weight-reducing holes. The hollow areas can penetrate the rotating wheel radially or axially, or they can not penetrate it. Of course, the rotating wheel can also be left untreated for weight reduction.

[0091] Please refer to Figures 7 and 8. A first rotating shaft 413 is provided at the eccentric part of the first driving member 411, and the first driven member 412 is rotatably connected to the first driving member 411 through the first rotating shaft 413. The first rotating shaft 413 is fixed to the first driving member 411, and the fixing method includes, but is not limited to, welding connection, integral molding, plug connection, etc., which can satisfy the requirement that the first rotating shaft 413 is fixed to the first driving member 411 and rotates with the first driving member 411. There are multiple ways to realize the rotatable connection between the first driven member 412 and the first rotating shaft 413. For example, the first driven member 412 is provided with a through hole, and the first rotating shaft 413 passes through the through hole and rotates with the first driven member 412; or a bearing is fixed to the first driven member 412, and the first rotating shaft 413 is fixed to the inner ring of the bearing, so that the first driven member 412 and the first rotating shaft 413 are rotatably connected; or other methods to make the first driven member 412 and the first rotating shaft 413 rotatably connected.

[0092] Please refer to Figures 7 and 8. In one embodiment, the second active member 421 is fixed to the first active member 411 via the first rotating shaft 413. The second active member 421 and the first active member 411 are respectively disposed at both ends of the first rotating shaft 413 to avoid interference between the first driven member 412 and the second active member 421 when the first driven member 412 rotates, so that the first driven member 412 moves along a predetermined trajectory and effectively ensures that the second active member 421 moves synchronously with the first active member 411.

[0093] The first rotating shaft 413 is fixed to the first active member 411, and the fixing method includes, but is not limited to, welding connection, integral molding, plug connection, etc.

[0094] Referring to Figures 7 and 8, in one embodiment, the second active member 421 is a rotating wheel. The rotating wheel can balance the forces acting on the second active member 421 during rotation, effectively improving the stability of the second active member 421 during rotation. The rotating wheel can be weight-reduced, for example, by providing a hollow area or weight-reducing holes on the rotating wheel, or the rotating wheel can be left untreated.

[0095] Referring to Figures 7 and 8, in one embodiment, a second rotating shaft 423 is provided at the eccentric position of the second driving member 421, and the second driven member 422 is rotatably connected to the second driving member 421 via the second rotating shaft 423. The second rotating shaft 423 can be rotatably mounted on the second driving member 421 or fixedly mounted on the second driving member 421. Preferably, the second rotating shaft 423 is fixedly mounted on the second driving member 421 to facilitate the fixing of other components, such as a third driving member, a support wheel 440, etc., on the side of the second rotating shaft 423 opposite to the second driving member 421. The fixing method between the second rotating shaft 423 and the second driving member 421 can be welding connection, integral molding, plug-in connection, interference fit, etc. When the second rotating shaft 423 is rotatably mounted on the second driving member 421, the second driven member 422 can be rotatably connected to the second rotating shaft 423 or fixedly connected; when the second rotating shaft 423 is fixedly mounted on the second driving member 421, the second driven member 422 is rotatably connected to the second rotating shaft 423; there are multiple ways in which the second driven member 422 and the second rotating shaft 423 can be rotatably connected. For example, the second driven member 422 is provided with a through hole, and the second rotating shaft 423 passes through the through hole on the second driven member 422 and rotates with the second driven member 422.

[0096] Referring to Figure 9, in one embodiment, the angle α between the second rotating shaft 423 and the first rotating shaft 413 about the axis of the second driving member 421 is 45° to 135°. The angle α can be any value between 45° and 135°, such as 45°, 60°, 90°, 100°, 135°, etc. The first lifting member 200 and the second lifting member 300 can be configured in different position combinations as needed. For example, when the first lifting member 200 is in the first position, the second lifting member 300 is in the third or fourth position; when the first lifting member 200 is in the second position, the second lifting member 300 is in the third or fourth position. By setting the angle α between the second rotating shaft 423 and the first rotating shaft 413, different position combinations between the first lifting member 200 and the second lifting member 300 can be effectively ensured, thereby effectively guaranteeing the functional effects of the first lifting member 200 and the second lifting member 300. It is understood that the axis of the second rotating shaft 423 and the center of the second driving member 421 can form a first connecting line, and the axis of the first rotating shaft 413 and the center of the second driving member 421 can form a second connecting line. The angle α between the second rotating shaft 423 and the first rotating shaft 413 about the axis of the second driving member 421 is the angle formed by the first connecting line and the second connecting line.

[0097] For example, the retracted position of the first lifting member 200 is the first position, and the functional position is the second position. The retracted position of the second lifting member 300 is the third position, and the functional position is the fourth position. The first lifting member 200 and the second lifting member 300 do not act simultaneously. The included angle α between the second rotating shaft 423 and the first rotating shaft 413 can achieve the following: when the first lifting member 200 is in the functional position, the second lifting member 300 is in the non-functional position. Similarly, when the second lifting member 300 is in the functional position, the first lifting member 200 is in the non-functional position.

[0098] Of course, as some alternatives, the included angle α between the second rotating shaft 423 and the first rotating shaft 413 can also be other values ​​other than 45° to 135°. For example, when the first lifting member 200 and the second lifting member 300 need to perform functions synchronously, the included angle α between the first rotating shaft 413 and the second rotating shaft 423 is 0° or 180°.

[0099] The first driven member 412 can be a rod-shaped structure, or it can be bent or shaped according to the position of the first driving member 411 and the first lifting member 200, as well as the spatial layout of the housing 100, so as to drive the first lifting member 200 to move along a predetermined trajectory, and the first driven member 412 does not interfere with other components during the movement.

[0100] Similarly, the second driven member 422 can be a straight rod structure or have a bent part, or it can be an irregular structure, as long as it can drive the second lifting member 300 to move along a predetermined trajectory, and the second driven member 422 does not interfere with other components during the movement.

[0101] Referring to Figure 8, in one embodiment, the cleaning assembly includes a support wheel 440, which is fixed to the second driving member 421 and rotatably mounted on the housing 100. By rotating the support wheel 440 mounted on the housing 100, the drive mechanism 400 can be supported. The drive mechanism 400 is no longer cantilevered by the drive unit 430, but is instead supported jointly by the drive unit 430 and the support wheel 440. This reduces the radial shear force on the drive unit 430, lowers the risk of damage to the drive unit 430, and increases the service life of the drive unit 430.

[0102] In one embodiment, the support wheel 440 is fixedly connected to the second rotating shaft 423 so that the support wheel 440 is fixed to the second driving member 421.

[0103] Of course, as an alternative, the support wheel 440 can also be rotatably connected to the second driving member 421. For example, the end of the second rotating shaft 423 away from the second driving member 421 can be bent and rotatably connected to the axis of the support wheel 440. The support wheel 440 can provide support for the drive mechanism 400.

[0104] In one embodiment, with the forward direction of the cleaning device as the front side, the second lifting member 300 in the fourth position is located behind the suction port 141 and abuts against the surface to be cleaned. After the cleaning components of the cleaning assembly, such as the roller brush module 600, clean, some dust particles remain temporarily in the suction chamber 140. As the cleaning device moves forward, there is a risk that the dust particles may escape from the rear side of the suction port 141. On the one hand, the second lifting member 300 can scrape away the dust and debris that have not yet been cleaned. On the other hand, the second lifting member 300 can close the rear side of the suction port 141, thereby reducing the situation where dust and debris remain on the surface to be cleaned after the cleaning assembly moves, and improving the cleaning ability of the cleaning assembly.

[0105] In one embodiment, in the fourth position, the second linkage assembly 420 applies a force to the second lifting member 300, causing the second lifting member 300 to press against the surface to be cleaned, that is, the second lifting member 300 abuts against the surface to be cleaned and there is pressure, so that the second lifting member 300 is close to the surface to be cleaned, so as to effectively clean the surface to be cleaned.

[0106] Please refer to Figures 3 and 11. In one embodiment, the part of the second lifting member 300 that abuts against the surface to be cleaned is a flexible part 310. The second lifting member 300 at the fourth position has a first interference fit with the surface to be cleaned. In other words, the second lifting member 300 at the fourth position is close to the surface to be cleaned, effectively sealing the rear side of the suction port 141, reducing the escape of dust particles and other debris from the rear side of the suction port 141, improving the ability of the second lifting member 300 to scrape dust and debris, and effectively improving the cleaning effect of the second lifting member 300.

[0107] In one embodiment, when the second lifting member 300 is in the fourth position, the flexible part 310 is perpendicular to the surface to be cleaned from top to bottom. The flexible part 310 is close to the surface to be cleaned, so as to facilitate the first lifting member to close the rear side of the suction port 141 and to facilitate the flexible part 310 to scrape away dust, particles and other objects on the surface to be cleaned.

[0108] In one embodiment, when the second lifting member 300 is in the fourth position, the flexible part 310 tilts downwards in the opposite direction to the forward direction of the cleaning equipment, which facilitates the relative movement of the flexible part 310 and the surface to be cleaned when the cleaning equipment moves forward. This effectively protects the second lifting member 300, delays the wear of the second lifting member 300, extends the service life of the second lifting member 300, and at the same time reduces the forward resistance of the cleaning equipment, saving energy and reducing consumption.

[0109] Referring to Figure 3, in one embodiment, a second cover plate 120 is provided on the rear side of the housing 100. The second cover plate 120 and the surface of the housing 100 form a second limiting groove 121, and the second lifting member 300 moves along the second limiting groove 121. On the one hand, the second cover plate 120 protects the second lifting member 300 from damage; on the other hand, the second limiting groove 121 formed between the second cover plate 120 and the housing 100 restricts the movement path of the second lifting member 300, so that the second lifting member 300 moves between a third position and a fourth position along the second limiting groove 121. For example, the second lifting member 300 can move along the surface of the housing 100 to avoid interference with other components during the movement of the second lifting member 300. At the same time, the addition of the second lifting member 300 has little impact on the original structure of the cleaning assembly, which facilitates the structural design of the cleaning assembly.

[0110] The movement path of the second driving member 421 is determined by the driving unit 430, and the movement path of the second lifting member 300 is limited by the second limiting groove 121. Together, they determine the movement path of the second driven member 422, thereby facilitating the arrangement of the second driven member 422 and avoiding interference with other components during the movement.

[0111] It should be noted that when the fourth position of the second lifting member 300 is the functional position, the third position is the retracted position. The retracted position can be a fixed position, or any position where the second lifting member 300 does not function can be referred to as the retracted position. For example, any position where the second lifting member 300 does not contact the surface being cleaned and does not obstruct the rear side of the suction port 141 can be referred to as the retracted position, i.e., the third position.

[0112] Due to structural limitations, the existing housing 100 typically has a mounting portion 130 extending away from the suction chamber 140 on its rear side, meaning the mounting portion 130 extends outward from the cleaning assembly. If the second lifting member 300 is directly positioned on the side of the mounting portion 130 away from the suction chamber 140, it will increase the volume of the cleaning assembly, resulting in an excessively large cleaning device body, limiting the cleaning area of ​​the cleaning device, and affecting the application scenarios of the cleaning device.

[0113] Referring to Figures 3 and 5, in one embodiment, the rear side of the housing 100 is provided with a mounting portion 130 extending away from the suction chamber 140, and the mounting portion 130 is provided with a through hole. As shown in Figure 11, the second lifting member 300 includes an upper lifting portion 320 and a lower lifting portion 330. The upper lifting portion 320 is disposed on the upper side of the mounting portion 130 and is rotatably connected to the second connecting rod assembly 420; the lower lifting portion 330 is disposed on the lower side of the mounting portion 130. The upper lifting portion 320 and the lower lifting portion 330 are respectively disposed on the upper and lower sides of the mounting portion 130. The second lifting member 300 is installed using the space above and below the mounting portion 130, which effectively reduces the impact of the second lifting member 300 on the volume of the cleaning component.

[0114] Referring to Figure 5, the cleaning assembly includes a reset member 340, which is mounted on the housing 100 and connected to the lower lifting part 330 to apply a force to the lower lifting part 330 toward the mounting part 130, thereby moving the lower lifting part 330 to a third position. The upper lifting part 320 and / or the lower lifting part 330 are provided with through holes and abutment portions 350, allowing the upper lifting part 320 to abut against the lower lifting part 330. When the second lifting member 300 moves to the fourth position, the upper lifting part 320 and the lower lifting part 330 are pressed together to move the lower lifting part 330. When the second lifting member 300 moves to the third position, the upper lifting part 320 is driven by the first connecting rod assembly 410, and the lower lifting part 330 is driven by the reset member 340, thus moving the second lifting member 300 to the third position.

[0115] Please refer to Figures 5 and 11. The abutment part 350 can be provided on the upper lifting part 320 or on the lower lifting part 330. Alternatively, the abutment part 350 can be provided on both the upper lifting part 320 and the lower lifting part 330. The abutment part 350 passes through the through hole and moves within the through hole, so that when the upper lifting part 320 moves to the fourth position, the upper lifting part 320 abuts against the lower lifting part 330, thereby driving the lower lifting part 330 to move to the fourth position.

[0116] The reset member 340 can be an elastic member, such as a spring or torsion spring, to apply a force to the lower lifting part 330 toward the mounting part 130 using its own elasticity, so that the lower lifting part 330 can move to the third position.

[0117] In another embodiment, the second lifting member 300 includes an upper lifting portion 320 and a lower lifting portion 330. The upper lifting portion 320 is disposed on the upper side of the mounting portion 130 and is rotatably connected to the second connecting rod assembly 420; the lower lifting portion 330 is disposed on the lower side of the mounting portion 130. The upper lifting portion 320 and / or the lower lifting portion 330 are provided with connecting portions through through holes, so that the upper lifting portion 320 and the lower lifting portion 330 are fixedly connected. The upper lifting portion 320 and the lower lifting portion 330 are fixed after being installed on the upper and lower sides of the mounting portion 130, respectively, which facilitates the assembly of the second lifting member 300, effectively realizes the synchronous movement of the upper lifting portion 320 and the lower lifting portion 330, and avoids the problem of the cleaning component being large due to the second lifting portion being located on the side of the mounting portion 130 away from the suction chamber 140, thus improving the integration of the cleaning component.

[0118] The connecting part can be provided on the upper lifting part 320, and the connecting part passes through the through hole from the top and connects to the lower lifting part 330; the connecting part can also be provided on the lower lifting part 330, and the connecting part passes through the through hole from the bottom and connects to the upper lifting part 320; the connecting part can also be provided on the upper lifting part 320 and the lower lifting part 330 respectively, so that the upper lifting part 320 and the lower lifting part 330 are respectively installed above and below the mounting part 130 and are relatively fixed.

[0119] Referring to Figure 3, in one embodiment, a first cover plate 110 is provided on the front side of the housing 100. The first cover plate 110 and the surface of the housing 100 form a first limiting groove 111. The first lifting member 200 is at least partially disposed within the first limiting groove 111, and the first lifting member 200 moves along the first limiting groove 111. On the one hand, the first cover plate 110 protects the first lifting member 200, reducing the risk of the first lifting member 200 being damaged by impact. On the other hand, the first limiting groove 111, which accommodates the sliding of the first lifting member 200, is formed between the first cover plate 110 and the housing 100. The first limiting groove 111 limits the movement of the first lifting member 200, allowing the first lifting member 200 to move between a first position and a second position along the first limiting groove 111, thus preventing interference with other components during the movement of the first lifting member 200.

[0120] The movement path of the first active member 411 is determined by the drive unit 430, and the movement path of the first lifting member 200 is limited by the first limiting groove 111. Together, they determine the movement path of the first driven member 412, thereby facilitating the arrangement of the first driven member 412 and avoiding interference with other components during the movement of the first driven member 412.

[0121] In one embodiment, when the first lifting member 200 is in the second position, it partially covers the front side of the suction port 141, so that the ventilation area of ​​the front side of the suction port 141 is smaller than the ventilation area of ​​the first lifting member 200 in the first position. The reduced ventilation area of ​​the front side of the suction port 141 in the second position increases the air velocity and pressure of the suction port 141 while maintaining the same suction power, effectively improving the adsorption capacity for dust, hair, etc., and meeting the usage needs of the cleaning component in different scenarios. For example, when the surface to be cleaned is a carpet, dust, particles, etc., may be hidden deep within the carpet. By covering part of the front area of ​​the suction port 141 with the first lifting member 200, the suction power of the front part of the suction port 141 is increased, making it easier to clean dust, particles, etc., deep within the carpet, expanding the application scenarios of the cleaning equipment and meeting the usage requirements of the cleaning equipment on different surfaces.

[0122] It should be noted that when the second position of the first lifting member 200 is the functional position, the first position is the retracted position. The retracted position can be a fixed position, or any position where the first lifting member 200 does not function can be referred to as the retracted position. For example, the first position is when the first lifting member 200 does not block the air intake at the front of the suction port 141.

[0123] The first lifting component 200 can be a flexible component, such as rubber, silicone, or flexible plastic; it can also be a rigid component, such as rigid plastic; or it can be a combination of flexible and rigid components, for example, the part connected to the first link assembly 410 is a rigid component, and the end away from the first link assembly 410 is a flexible component.

[0124] Of course, the first lifting component 200 can also be in other combinations, as long as the functional requirements of the first lifting component 200 are met.

[0125] Referring to Figures 1 and 4, in one embodiment, the cleaning assembly includes a detection module 500 configured to detect the rotation angle of a first active member 411 and / or a second active member 421 to determine the positions of a first lifting member 200 and a second lifting member 300. The second active member 421 rotates synchronously with the first active member 411. By detecting the rotation angle of the first active member 411 and / or the second active member 421, the current positions of the first lifting member 200 and the second lifting member 300 can be determined. This allows the drive unit 430 to stop moving when the first lifting member 200 and the second lifting member 300 reach a desired position, thus maintaining the first lifting member 200 and the second lifting member 300 in the desired position.

[0126] In one embodiment, the detection module 500 includes a calibration module and a determination module. The calibration module includes a calibration sensor and a calibration sensing area. One of the calibration sensor and the calibration sensing area is fixed to the housing 100, and the other is fixed to the first active member 411. The calibration module is triggered when the calibration sensing area coincides with the calibration sensor. The determination module includes a determination sensor and at least two determination sensing areas. One of the determination sensor and the determination sensing area is fixed to the housing 100, and the other is fixed to the first active member 411. The determination module is triggered when the determination sensing area coincides with the determination sensor. When the first active component 411 rotates to a calibrated angle, the calibration module is triggered. At this time, the first lifting component 200 and the second lifting component 300 have a first position state combination. Because there is only one calibration sensing area, the rotation angle of the first active component 411 is also unique when the calibration module is triggered. The calibration module can calibrate the rotation angle of the first active component 411 to ensure that the first active component 411 can be calibrated at any angle when the cleaning equipment is turned on, thereby controlling the first lifting component 200 and the second lifting component 300 to move to a suitable preset position. When the first active component 411 continues to rotate, the determination sensor is triggered once. At this time, the first lifting component 200 and the second lifting component 300 have a second position state combination. When the first active component 411 continues to rotate until the determination sensor is triggered twice, the first lifting component 200 and the second lifting component 300 have a third position state combination. By triggering the calibration module and the judgment module respectively, the position state combination of the first lifting component 200 and the second lifting component 300 can be obtained, thereby realizing the control of the position of the first lifting component 200 and the second lifting component 300, effectively ensuring the functional realization of the first lifting component 200 and the second lifting component 300.

[0127] In one embodiment, the detection module 500 has at least three trigger positions within one rotation cycle of the first active member 411 and / or the second active member 421. The first active member 411 and the second active member 421 are relatively fixed, therefore their rotation cycles are the same. The three trigger positions correspond to different positional combinations of the first lifting member 200 and the second lifting member 300, thereby controlling the positions of the first lifting member 200 and the second lifting member 300 so that they can remain at the expected positions.

[0128] For example, if the first active member 411 rotates in one direction, one rotation cycle is one revolution of the first active member 411; if the first active member 411 rotates in a reciprocating motion, one reciprocating motion is two rotation cycles.

[0129] Of course, as some alternatives, the rotation cycle of the first active member 411 can also have other options, such that the first lifting member 200 has a first position and a second position, and the second lifting member 300 has a third position and a fourth position within one rotation cycle.

[0130] In one embodiment, the detection module includes a detector and a detection element. One of the detection element and the detector is fixed relative to the first active member 411, and the other is fixed relative to the housing 100. The detection element triggers the detector at least three times within one rotation cycle of the first active member 411. One of the detection element or the detector rotates synchronously with the first active member 411, and the other is fixed relative to the housing 100. When the first active member 411 rotates to a preset position, the detection element triggers the detector, thereby monitoring the rotation angle of the first active member 411. When the first active member 411 rotates to the expected position, the drive unit 430 is controlled to stop the first active member 411, so that the first lifting member 200 and the second lifting member 300 stop at the expected position.

[0131] Referring to Figure 10, in one embodiment, the detection element includes a first detection element 510 and a second detection element 530, and the detector includes a first detector 520 and a second detector 540. The first detection element 510 is fixed relative to the first active element 411, and has at least one first detection area 511. The first detector 520 is fixed relative to the housing 100, and is triggered when the first detection area 511 rotates to the position of the first detector 520. The second detection element 530 is fixed relative to the first active element 411, and has at least one second detection area 531. The second detector 540 is fixed relative to the housing 100, and is triggered when the second detection area 531 rotates to the position of the second detector 540. By setting the first detector 520 and the second detector 540, on the one hand, the rotation angle of the first active member 411 can be calibrated by triggering the first detector 520 and / or the second detector 540; on the other hand, the preset rotation angle of the first active member 411 can be determined, thereby determining the position of the first lifting member 200 and the second lifting member 300 based on the rotation angle of the first active member 411, and then controlling the start and stop of the drive unit 430 so that the first lifting member 200 and the second lifting member 300 are kept in the expected position. For example, the first lifting member 200 is set on the front side of the housing 100 to block part of the air intake area on the front side of the suction port 141, and the second lifting member 300 is set on the rear side of the housing 100 to scrape dust particles and other objects close to the ground and reduce the escape of dust particles. The first lifting member 200 and the second lifting member 300 need to have three different position state combinations: when the first lifting member 200 is in the second functional position, the second lifting member 300 is in the third retracted position; when the first lifting member 200 is in the first retracted position, the second lifting member 300 is in the fourth functional position; when the first lifting member 200 is in the first retracted position, the second lifting member 300 is in the third retracted position. The first detector 520 and / or the second detector 540 are triggered three times by the three preset rotation angles of the first active member 411, thereby determining the three position state combinations of the first lifting member 200 and the second lifting member 300 to realize the functions of the first lifting member 200 and the second lifting member 300.

[0132] The first active member 411 has at least three preset rotation angles that can trigger the first detector 520 and the second detector 540. The preset rotation angles correspond to different position state combinations of the first lifting member 200 and the second lifting member 300. By triggering at least three preset rotation angles, it can be determined that the first lifting member 200 and the second lifting member 300 have at least three position state combinations to satisfy the functions of the first lifting member 200 and the second lifting member 300.

[0133] Of course, the preset rotation angle of the first active component 411 can be set as needed, such as three, four, five, etc., so that the first lifting component 200 and the second lifting component 300 can stay in different position combinations to meet different usage requirements.

[0134] Referring to Figure 10, in one embodiment, there is one first detection area 511 and two second detection areas 531. The first detection area 511 and the second detection area 531 do not trigger the first detector 520 and the second detector 540 simultaneously. In other words, when the first detection area 511 triggers the first detector 520, the second detection area 531 does not trigger the second detector 540; similarly, when the second detection area 531 triggers the second detector 540, the first detection area 511 does not trigger the first detector 520. When the first detector 520 triggers the second detector 520, it means that the first lifting member 200 and the second lifting member 300 are in a first position state combination. Then, when the drive unit 430 continues to work, the number of times the second detector 540 is triggered by the second detection area 531 can determine the rotation angle of the first driving member 411 when the second detector 540 is triggered, and thus determine the current position state combination of the first lifting member 200 and the second lifting member 300. When the cleaning assembly starts working but cannot determine the current position combination of the first lifting member 200 and the second lifting member 300, it first drives the first active member 411 to rotate to the trigger angle of the first detector 520 via the drive unit 430. At this time, the rotation angle of the first active member 411 is determined, and the rotation angle of the first active member 411 can be calibrated. If the current rotation angle of the first active member 411 is not the expected angle, the drive unit 430 continues to work to drive the first active member 411 to rotate to the second detector 540 for one or two triggers, then the drive unit 430 stops, so that the first lifting member 200 and the second lifting member 300 move to the expected position.

[0135] Of course, as some alternatives, the second detection zone 531 may also have three, four or more, depending on the usage requirements of the first lifting member 200 and the second lifting member 300.

[0136] Of course, the first detector 520 can also be used only to calibrate the rotation angle of the first active member 411, and determine the position state combination of the first lifting member 200 and the second lifting member 300 based on the number of triggers of the second detector 540, thereby controlling the start and stop of the drive unit 430.

[0137] In one embodiment, the first detection area 511 and the second detection area 531 do not coincide in the direction of the rotation axis of the first active member 411. The non-coincidence of the positions of the first detection area 511 and the second detection area 531 means that the first detector 520 and the second detector 540 are not triggered at the same time, thereby determining different rotation angles of the first active member 411 and identifying different positional combinations of the first lifting member 200 and the second lifting member 300.

[0138] In one embodiment, two first detection areas 511 and two second detection areas 531 are provided. One first detection area 511 and one second detection area 531 simultaneously trigger the first detector 520 and the second detector 540, respectively. The other first detection area 511 and the second detection area 531 do not simultaneously trigger the first detector 520 and the second detector 540. When the first detector 520 and the second detector 540 are triggered simultaneously, the rotation angle of the first active member 411 can be determined, that is, a positional combination of the first lifting member 200 and the second lifting member 300 can be determined. When the first detector 520 and the second detector 540 are triggered separately, two other rotation angles of the first active member 411 can be determined, thereby determining two other positional combinations of the first lifting member 200 and the second lifting member 300. By determining the three rotation angles of the first active member 411 based on the cooperation of the first detector 520 and the second detector 540, three different positional combinations of the first lifting member 200 and the second lifting member 300 are obtained, facilitating the control of the positions of the first lifting member 200 and the second lifting member 300.

[0139] Of course, the number of the first detection area 511 and the second detection area 531 can be increased as needed. The first detector 520 and the second detector 540 only need to be triggered once at the same time to calibrate the rotation angle of the first active member 411. When the first lifting member 200 or the second lifting member 300 needs to adjust its position, if the current position of the first lifting member 200 or the second lifting member 300 is unclear, the rotation angle of the first active member 411 can be calibrated, thereby controlling the first lifting member 200 and the second lifting member 300 to move to a suitable position state combination.

[0140] Referring to Figure 10, in one embodiment, the first detection element 510 and the second detection element 530 are disc-type detection elements, the first detection area 511 and the second detection area 531 are through detection holes on the disc-type detection elements, and the first detector 520 and the second detector 540 are optical couplers. When the disc-type detection element rotates, the force on the drive unit 430 is more uniform, reducing the radial shear force on the drive unit 430 and improving the service life of the drive unit 430. The through detection holes and optical couplers make it easier to trigger the detectors, which is convenient to implement and has a lower cost.

[0141] The disc-type detection component can be weight-reduced in non-detection areas to decrease its weight and lower the requirements for the drive unit 430. Of course, the disc-type detection component can also be left unweighted.

[0142] Referring to Figures 4 and 10, in one embodiment, the cleaning assembly includes a support wheel 440 and a connecting shaft 450. The support wheel 440 is fixed to the second driving member 421 and is rotatably mounted on the housing 100. The support wheel 440 supports the drive mechanism 400, reducing the load on the drive unit 430 and improving its service life. The connecting shaft 450 is fixedly mounted on the axle of the support wheel 440. A first detection element 510 is fixedly mounted on the connecting shaft 450, so that the first detection element 510 is fixed to the support wheel 440. Since the support wheel 440 is relatively fixed to the first driving member 411, the first detection element 510 is also relatively fixed to the first driving member 411. A second detection element 530 is fixedly mounted on the connecting shaft 450 on the side of the first detection element 510 away from the support wheel 440. The second detection element 530 is relatively fixed to the first driving member 411, and both the first detection element 510 and the second detection element 530 rotate synchronously with the first driving member 411. The first detection element 510 and the second detection element 530 are located on the side of the support wheel 440 away from the drive unit 430, which can avoid the problem that the large span on the drive mechanism 400 side is easily damaged. At the same time, the support wheel 440 can also provide support for the first detection element 510 and the second detection element 530, improving the stability of the operation of the first detection element 510 and the second detection element 530.

[0143] Referring to Figures 4 and 10, in one embodiment, the cleaning assembly includes a rotary bearing 460, which is fixedly mounted on the housing 100, and the connecting shaft 450 is fixed to the inner ring of the rotary bearing 460. The rotary bearing 460 is located on the side of the second detection element 530 away from the first detection element 510. The support wheel 440 and the rotary bearing 460 are respectively located on both sides of the detection module 500, providing support for both ends of the detection module 500, improving the stability of the detection module 500 during rotation, and improving the accuracy of detection, so as to control the first lifting element 200 and the second lifting element 300 to accurately stop in the appropriate position.

[0144] A second aspect of this application provides a cleaning device, including a device body and a cleaning component as described above, wherein the cleaning component is mounted on the device body. The cleaning component drives two linkage assemblies via a drive unit 430, thereby moving the first lifting member 200 and the second lifting member 300, reducing the number of drive units 430 required for the cleaning device and lowering the cost and weight of the cleaning device.

[0145] The cleaning assembly uses a drive unit 430 to drive a first linkage assembly 410 and a second linkage assembly 420, thereby causing the first lifting member 200 to move between a first position and a second position, and the second lifting member 300 to move between a third position and a fourth position. By using a single drive unit 430 and two linkage assemblies within a drive mechanism 400 to move the two lifting members, the number of drive units 430 is effectively reduced, costs are lowered, and the spatial layout of the cleaning assembly is facilitated. Therefore, this application effectively overcomes some practical problems in the prior art and thus has high utilization value and practical significance.

[0146] 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.
