[0001] Cross-references to related applications
[0002] This application claims the benefit of Chinese Patent Application No. 202520132687.8, 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 technology, specifically to a cleaning component and cleaning equipment. Background Technology
[0004] With technological advancements, cleaning robots and other cleaning equipment are gaining increasing acceptance among users, leading to higher demands. Cleaning equipment typically includes cleaning components such as mops and brushes, usually equipped with a drive mechanism to raise and lower these components. However, existing drive mechanisms are limited to raising and lowering these components, resulting in a relatively low frequency of movement and significant idle time. As the demands on cleaning equipment increase, additional moving parts relative to the main body are often incorporated to meet diverse needs. For example, a retractable squeegee can be added to improve cleaning efficiency when there is a lot of dust or hair on the floor. With more moving parts, the required drive mechanism increases. Therefore, effectively utilizing the lifting drive mechanism to improve its utilization rate and reduce the number of drive mechanisms has become a pressing issue. 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 problem that the existing cleaning component lifting drive device has a single function and cannot be combined with other drive mechanisms.
[0006] To achieve the above and other related objectives, a first aspect of this application provides a cleaning component disposed on the main body of a cleaning device. The cleaning component includes at least one cleaning element, and the cleaning element has at least a third position and a fourth position on the cleaning device. The cleaning component includes a housing, a first lifting element, a first transmission mechanism, a drive unit, a second transmission mechanism, and a clutch. A suction chamber is formed within the housing, and a suction port is opened at one end of the suction chamber facing the surface to be cleaned. The first lifting element is disposed in the housing and has at least a first position and a second position. The first transmission mechanism drives the first lifting element to move between the first position and the second position. The drive unit is disposed in the housing and drives the first transmission mechanism to move. The second transmission mechanism drives the cleaning element to move between the third position and the fourth position. The clutch is connected to both the drive unit and the second transmission mechanism to control the connection between the drive unit and the second transmission mechanism.
[0007] The first transmission mechanism of the cleaning component is directly connected to the drive unit, and the second transmission mechanism is connected to the drive unit through a clutch. The clutch controls the connection between the drive unit and the second transmission mechanism. When the cleaning component does not need to be raised or lowered, the clutch controls the drive unit to disconnect from the second transmission mechanism, and the drive unit drives the first transmission mechanism alone to move the first lifting component. The first lifting component utilizes the drive unit for the raising and lowering of the cleaning component, which expands the function of the drive unit for the raising and lowering of the cleaning component, effectively reduces the number of drive units, reduces costs, and facilitates the spatial layout of the cleaning component.
[0008] In an exemplary embodiment of this application, the clutch includes a drive wheel, a transmission wheel, and an intermediate wheel. The drive wheel is connected to the drive unit and has a first transmission part. The transmission wheel is connected to the first transmission mechanism and has a fourth transmission part extending spirally in a first direction. The intermediate wheel has a second transmission part opposite to the first transmission part and a third transmission part opposite to the fourth transmission part, the third transmission part extending spirally in the first direction. The first transmission part cooperates with the second transmission part to drive the intermediate wheel to rotate forward when the drive wheel rotates forward, and to move towards the transmission wheel to the point where the third transmission part and the fourth transmission part cooperate, thereby driving the transmission wheel to rotate forward. When the drive wheel rotates in reverse, the third transmission part disengages from the fourth transmission part.
[0009] When the drive wheel rotates clockwise, the first and second transmission units cooperate, causing the intermediate wheel to move towards the drive wheel. This, in turn, causes the third and fourth transmission units to cooperate, meaning the intermediate wheel drives the drive wheel to rotate, and the drive unit drives the second transmission mechanism. When the drive wheel rotates counterclockwise, under the action of the third and fourth transmission units, the intermediate wheel moves towards the drive wheel until the third and fourth transmission units separate or only make contact without transmission. In this case, the second transmission mechanism is not driven by the drive unit, meaning the drive unit does not drive the cleaning component. The connection between the drive unit and the second transmission mechanism is switched on and off through the cooperation of the first and second transmission units, as well as the cooperation of the third and fourth transmission units, simplifying control.
[0010] In an exemplary embodiment of this application, the first transmission part includes a first rib, which is disposed on the side of the drive wheel facing the intermediate wheel, and the first rib is inclined away from the intermediate wheel along the forward rotation direction.
[0011] The first rib is inclined away from the intermediate wheel in the direction of forward rotation. In other words, the rear side of the first rib is closer to the intermediate wheel than the front side in the direction of forward rotation. When the drive wheel rotates forward, the second transmission part cooperates with the first transmission part. The second transmission part moves along the surface of the first rib. Since the drive wheel does not move horizontally, the translation component applied to the second transmission part by the first rib causes the intermediate wheel to move away from the drive wheel, that is, the intermediate wheel moves closer to the transmission wheel, so that the third transmission part cooperates with the fourth transmission part, and the intermediate wheel drives the transmission wheel to rotate.
[0012] In an exemplary embodiment of this application, the first transmission part includes a first limiting block, which cooperates with the second transmission part to cause the drive wheel to drive the intermediate wheel to rotate.
[0013] The combined action of the first rib and the first limiting block enables the drive wheel to both drive the intermediate wheel to rotate and, when the drive wheel rotates forward, to move the intermediate wheel away from the drive wheel.
[0014] In an exemplary embodiment of this application, the end of the first limiting block near the intermediate wheel extends beyond the end of the first rib near the intermediate wheel.
[0015] The first limiting block is closer to the intermediate wheel than the first rib, so that when the second transmission part moves to the end of the first rib, the first limiting block restricts the second transmission part from continuing to rotate relative to the first rib, which facilitates the drive part to drive the intermediate wheel to rotate.
[0016] In an exemplary embodiment of this application, the second transmission part includes a second rib and a second limiting block. The second rib is disposed on the side of the intermediate wheel facing the drive wheel, and the second rib is inclined towards the drive wheel in the forward rotation direction; the second limiting block cooperates with the first transmission part so that the drive wheel drives the intermediate wheel to rotate; wherein, the end of the second limiting block near the drive wheel extends beyond the end of the second rib near the drive wheel.
[0017] The second rib is inclined towards the drive wheel in the forward rotation direction. In other words, the rear side of the second rib in the reverse rotation direction is closer to the drive wheel than the front side. Since the second rib is positioned facing the drive wheel, when the drive wheel rotates forward, the second rib rotates in the reverse direction relative to the drive wheel. The first transmission part moves along the surface of the second rib, and the intermediate wheel moves away from the drive wheel, that is, the intermediate wheel moves away from the drive wheel and gets closer to the transmission wheel, so that the third and fourth transmission parts cooperate, and the intermediate wheel drives the transmission wheel to rotate. Through the combined action of the second rib and the second limiting block, the drive wheel can both drive the intermediate wheel to rotate and, when the drive wheel rotates forward, cause the intermediate wheel to move away from the drive wheel. The second limiting block is closer to the drive wheel than the second rib, so that when the first transmission part moves to the end of the second rib, the second limiting block restricts the first transmission part from continuing to rotate relative to the second rib, facilitating the drive part to drive the intermediate wheel to rotate.
[0018] In an exemplary embodiment of this application, the second transmission mechanism includes a spool and a traction member. The spool is connected to the clutch member so that when the drive unit is connected to the second transmission mechanism, the drive unit drives the spool to rotate; one end of the traction member is fixed to the spool, and the other end is fixed to the body of the cleaning device or the cleaning component, so that when the spool rotates, it drives the cleaning component to move between the third position and the fourth position.
[0019] One end of the traction component is fixed to the reel, and the other end is fixed to the main body of the cleaning equipment. When the reel rotates, the traction component winds around the reel, thereby driving the cleaning component and the cleaning assembly to move together relative to the main body of the cleaning equipment. When the clutch controls the drive unit to disconnect from the second transmission mechanism, under the gravity of the cleaning assembly, the cleaning assembly moves downward and drives the traction component to move, which in turn drives the reel to rotate until the cleaning assembly moves to the point where the traction component is fully open and no longer winds around the reel or other limited positions, at which point the cleaning assembly stops moving. The cleaning component moves to the fourth position (descending position) by gravity and to the third position (retracted position) driven by the traction component. The drive unit only needs to drive the cleaning component in the forward direction; when the drive unit reverses, it only drives the first transmission mechanism, expanding the application of the drive unit, reducing the number of drive units, and lowering costs.
[0020] When one end of the traction component is fixed to the reel and the other end is fixed to the cleaning component, the traction component winds around the reel as the reel rotates, thereby driving the cleaning component to move relative to the housing of the cleaning assembly. When the clutch controls the drive unit to disconnect from the second transmission mechanism, the cleaning component moves downward under the gravity of the cleaning component and drives the traction component to move, which in turn drives the reel to rotate until the cleaning component moves to the point where the traction component is fully open and no longer winds around the reel or other limiting positions, at which point the cleaning component stops moving.
[0021] In an exemplary embodiment of this application, the first transmission mechanism includes a first driving member and a first driven member. The first driving member is connected to the driving unit; the first driven member is rotatably disposed on the first driving member and rotatably connected to the first lifting member.
[0022] Through the combined action of the first driving member and the first driven member, the first lifting member is driven to move between the first position and the second position. The movement trajectory is stable and controllable, which facilitates structural design.
[0023] In an exemplary embodiment of this application, the clutch is fixed relative to the first driving member so that the clutch is connected to the driving unit.
[0024] The clutch component is fixed relative to the first driving component, which facilitates the arrangement of the second transmission mechanism and the first transmission mechanism along the axial direction of the drive unit, making full use of the space in the length direction of the cleaning component and facilitating the structural layout of the cleaning component.
[0025] In an exemplary embodiment of this application, the first driving member is a wheel structure, and the first driven member is rotatably disposed at the eccentric position of the first driving member.
[0026] The wheel structure can effectively balance the force on the drive unit, reduce the shear force on the drive unit, reduce the risk of damage to the drive unit, and improve the service life of the drive unit.
[0027] In an exemplary embodiment of this application, the cleaning assembly includes a third transmission mechanism and a second lifting member. The third transmission mechanism is connected to the first transmission mechanism; the second lifting member is disposed on the housing, and the second lifting member has at least a fifth position and a sixth position relative to the housing, and the third transmission mechanism drives the second lifting member to move between the fifth position and the sixth position.
[0028] By adding a third transmission mechanism, the movement of the second lifting component can be realized, thereby enabling the lifting drive unit of the cleaning component to drive the movement of multiple lifting components, realizing the multi-purpose use of the drive unit, expanding the application range of the drive unit, reducing the number of drive units required, reducing costs, and facilitating structural layout.
[0029] 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 sixth position is located behind the suction port and abuts against the surface being cleaned.
[0030] 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 component moves, and improving the cleaning ability of the cleaning component.
[0031] 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 sixth position has a first interference fit with the surface being cleaned.
[0032] 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.
[0033] In an exemplary embodiment of this application, the third transmission mechanism includes a third driving member and a third driven member. The third driving member is fixed to the first driving member; the third driven member is rotatably disposed on the third driving member and rotatably connected to the second lifting member.
[0034] The third driving member and the third driven member enable the drive unit to move the second lifting member between the fifth and sixth positions. By fixing the third driving member relative to the first driving member and rotating synchronously with the first driving member, the drive unit can simultaneously drive the first and second driving members to move, thereby causing the first and second lifting members to move simultaneously.
[0035] In an exemplary embodiment of this application, the first transmission mechanism includes a first rotating shaft fixedly disposed on the first driving member, the first driven member rotating around the first rotating shaft and the first driving member, and the third driving member being fixed to the first driving member through the first rotating shaft.
[0036] The first driven member rotates around the first rotating shaft, and the third driving member is fixed to the first driving member through the first rotating shaft to avoid collisions or interference between the first driven member and the third driving member when the first driven member rotates.
[0037] In an exemplary embodiment of this application, the cleaning assembly includes a support wheel. The support wheel is rotatably disposed on the housing; wherein, a second rotating shaft is disposed on the third driving member, and the third driven member is rotatably connected to the third driving member about the second rotating shaft; the support wheel is fixed to the third driving member through the second rotating shaft.
[0038] The support wheels can support the first transmission mechanism and other components to balance the forces on the drive unit and reduce the risk of damage to the drive unit.
[0039] In an exemplary embodiment of this application, the cleaning component includes a detection module. The detection module is configured to detect the rotational position of the first active member to obtain the position of the first lifting member.
[0040] The detection module detects the rotational position of the first active component, thereby obtaining the position of the first lifting component, so that the first lifting component can be accurately moved to the expected position.
[0041] 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, and the detection element triggers the detector at least twice within one rotation cycle of the first active element.
[0042] One of the detection element or detector 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, so that the first lifting element stops at the expected position.
[0043] In an exemplary embodiment of this application, the detection element includes a first detection element and a second detection element; the detector includes a first detector and a second detector. 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 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 detection element is fixed relative to the first active element, and the second detection element has at least one second detection area; 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.
[0044] By setting a first detector and a second detector, on the one hand, the rotation angle of the first active component can be calibrated by triggering the first detector and / or the second detector. On the other hand, the preset rotation angle of the first active component can be determined, thereby determining the two positions of the first lifting component based on the rotation angle of the first active component, and then controlling the start and stop of the drive unit so that the first lifting component stays at the expected position.
[0045] In an exemplary embodiment of this application, the driving unit includes a motor; the rotation angle by which the motor drives the cleaning component to move from a fourth position to a third position is a first stroke, and the rotation angle by which the motor drives the first lifting member between the first position and the second position is a second stroke, wherein the second stroke is an integer multiple of the first stroke.
[0046] When the drive unit rotates forward, it can drive the first transmission mechanism and the second transmission mechanism. When it rotates in reverse, it only drives the second transmission mechanism. The second stroke is adjusted to be an integer multiple of the first stroke. When the cleaning component needs to be raised to the third position, the first lifting member is first moved to the first position or the second position. Then, the drive unit rotates forward to drive the first lifting member and the cleaning component to move, so that when the cleaning component is raised to the third position, the first lifting member moves to the retracted first position.
[0047] In an exemplary embodiment of this application, the detection module is triggered when the first active member rotates to a third preset angle. When the first active member drives the cleaning component to move from the fourth position to the third position from the third preset angle, the first lifting member rises to the first position.
[0048] The detection module is triggered when the first active component rotates to the third preset angle. The first active component starts to move from the third preset angle, and when it moves the cleaning component from the fourth position to the third position, the first lifting component follows and rises to the first position. That is, when the cleaning component rises, the first lifting component rises at the same time, which facilitates the movement of the cleaning equipment.
[0049] 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.
[0050] 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.
[0051] 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.
[0052] 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.
[0053] 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.
[0054] The first lifting component of the cleaning equipment utilizes the drive unit of the cleaning assembly, effectively reducing the number of drive units, lowering costs, and facilitating the spatial layout of the cleaning assembly.
[0055] In combination with existing technologies, the beneficial effects of this application are as follows:
[0056] Existing cleaning equipment has a driving mechanism for its cleaning components to move relative to the main body of the equipment. Each additional moving component requires an additional driving mechanism, leading to increased costs and inconvenient space layout. This application includes a driving unit, a first transmission mechanism, and a second transmission mechanism. The first transmission mechanism is directly connected to the driving unit, and the second transmission mechanism is connected to the driving unit via a clutch. The clutch controls the connection between the driving unit and the second transmission mechanism. When the cleaning component does not need to be raised or lowered, the clutch disconnects the driving unit from the second transmission mechanism, allowing the driving unit to independently drive the first transmission mechanism to move the first lifting component. The first lifting component utilizes the driving unit for the raising and lowering of the cleaning component, effectively reducing the number of driving units, lowering costs, and facilitating the spatial layout of the cleaning components.

[0076] 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.
[0077] 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.
[0078] It should be noted that the terms such as "upper", "lower", "left", "right", "middle" and "one" used in this specification are only for clarity of description and are not intended to limit the scope of this application. 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.
[0079] For every additional component that moves relative to the cleaning unit in existing cleaning equipment, an additional drive mechanism is required, resulting in higher costs and inconvenient spatial layout.
[0080] In view of this, referring to Figures 1 to 18, the first aspect of this application provides a cleaning device 1, which includes a main body and a cleaning component 10.
[0081] It is understood that the specific type of cleaning device 1 is not limited in this application. Any device that cleans the surface to be cleaned using cleaning component 700 falls within the protection scope of cleaning device 1 in this application. Cleaning device 1 can be a sweeper, mop, or a combined sweeper and mop, etc.; specifically, it can be a handheld cleaning device 1, a vertical cleaning device 1, or a horizontal cleaning device 1; cleaning device 1 can be used to clean surfaces such as floors, tiles, carpets, and glass. Cleaning device 1 can be a wirelessly connected cleaning device 1 or a wired cleaning device 1.
[0082] Please refer to Figure 18. The cleaning component 10 is generally located at the bottom of the housing. The cleaning component 10 includes at least one cleaning element 700. The cleaning element 700 is movable in the direction of approaching and moving away from the main body. The cleaning element 700 has at least a third position and a fourth position relative to the main body. The third position refers to the position of the cleaning element 700 when it is close to the main body, and the fourth position refers to the position of the cleaning element 700 when it is away from the main body.
[0083] The specific form of the cleaning component 700 corresponds to the specific function of the cleaning equipment 1. It can be a brush, a cleaning cloth, a roller brush, etc. The cleaning component 10 can also have multiple cleaning components 700. The multiple cleaning components 700 can be the same cleaning component 700 or different cleaning components 700, depending on the specific function of the cleaning equipment 1.
[0084] In one embodiment, the cleaning component 700 and the housing 100 of the cleaning assembly 10 may be relatively fixed, and the cleaning component 700 may move together with the cleaning assembly 10 in directions toward and away from the main body of the cleaning device 1. In another embodiment, the cleaning assembly 10 and the main body of the cleaning device 1 may be relatively fixed, while the cleaning component 700 and the housing 100 may be movably disposed, thereby allowing the cleaning component 700 to move toward or away from the main body of the cleaning device 1. In other embodiments, the cleaning component 700, the cleaning assembly 10, and the main body of the cleaning device 1 may be connected in other ways to allow relative movement between the cleaning component 700 and the cleaning device 1, and / or relative movement between the cleaning assembly 10 and the cleaning device 1.
[0085] The cleaning device 1 can be used to clean floors, carpets, and glass, which makes its orientation in use varied and inconsistent. However, in order to facilitate a detailed explanation of the relative orientation relationships of the various components in the cleaning device 1, the following embodiments will use the cleaning device 1 placed on a horizontal surface such as the floor or carpet as an example. Therefore, the cleaning component 700 can move up and down.
[0086] The cleaning component 10 of the cleaning equipment 1 may include a negative pressure mechanism, which includes a suction chamber 140 and a negative pressure fan. The suction chamber 140 is connected to the surface to be cleaned and the negative pressure fan. The negative pressure fan draws negative pressure into the suction chamber 140 to remove dust, particles and other dirt from the surface to be cleaned. The negative pressure mechanism may include a housing 100, which may form a suction chamber 140. The housing 100 has a suction port 141 at one end facing the surface to be cleaned and a dust outlet at the other end connected to the suction duct. The suction duct may be connected to the dust inlet of the dust box, and the suction duct of the dust box may be connected to the negative pressure fan. The negative pressure fan may generate negative pressure in the suction chamber 140 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 141 and dust outlet of the housing 100, the suction duct, the dust box, and the negative pressure fan, and is discharged through the outlet of the negative pressure fan. The dirt is left in the dust box.
[0087] The cleaning component 10 of the cleaning device 1 may also include a roller brush module 600. The roller brush module 600 may include a roller brush drive and a roller brush. The roller brush may be disposed in the suction chamber, and the roller brush drive may be disposed 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. Then, by using negative pressure, the dirt is sucked into the dust box, thereby improving the cleaning effect of the cleaning component 10 on the cleaning surface such as dust and particulate matter.
[0088] Since this application mainly improves the structure of the cleaning component 10, the cleaning component 10 will be specifically described in the following embodiments with reference to the accompanying drawings.
[0089] Please refer to Figures 1 to 17. A second aspect of this application provides a cleaning assembly 10, disposed on the main body of a cleaning device 1. The cleaning assembly 10 has at least one cleaning component 700, and the cleaning component 700 has at least a third position and a fourth position on the cleaning device 1. The cleaning assembly 10 also includes a housing 100, a first lifting component 200, a first transmission mechanism 410, a drive unit 401, a second transmission mechanism 470, and a clutch component 430. A suction chamber 140 is formed within the housing 100, and a suction port 141 is provided at one end of the suction chamber 140 facing the surface to be cleaned. The first lifting member 200 is disposed on the housing 100, and the first lifting member 200 has at least a first position and a second position; the first transmission mechanism 410 drives the first lifting mechanism to move between the first position and the second position; the drive unit 401 is disposed on the housing 100, and the drive unit 401 drives the first transmission mechanism 410 to move; the second transmission mechanism 470 drives the cleaning member 700 to move between a third position and a fourth position; the clutch member 430 is connected to the drive unit 401 and the second transmission mechanism 470 respectively to control the connection between the drive unit 401 and the second transmission mechanism 470.
[0090] Please refer to Figure 5. The first transmission mechanism 410 of the cleaning component 10 is directly connected to the drive unit 401, and the second transmission mechanism 470 is connected to the drive unit 401 through a clutch 430. The clutch 430 controls the connection between the drive unit 401 and the second transmission mechanism 470. When the cleaning component 700 does not need to be raised or lowered, the clutch 430 controls the drive unit 401 to disconnect from the second transmission mechanism 470. The drive unit 401 drives the first transmission mechanism 410 alone to move the first lifting component 200. The first lifting component 200 utilizes the drive unit 401 that raises and lowers the cleaning component 700, effectively reducing the number of drive units 401, reducing costs, and facilitating the spatial layout of the cleaning component 10.
[0091] Please refer to Figures 6-13. In one embodiment, the clutch 430 includes a drive wheel 431, a transmission wheel 432, and an intermediate wheel 433. The drive wheel 431 is connected to the drive unit 401, and a first transmission unit 4311 is provided on the drive wheel 431; the transmission wheel 432 is connected to the first transmission mechanism 410, and a fourth transmission unit 4321 extending spirally in a first direction is provided on the transmission wheel 432; the intermediate wheel 433 is provided with a second transmission unit 4331 opposite to the first transmission unit 4311, and a third transmission unit 4334 opposite to the fourth transmission unit 4321, and the third transmission unit 4334 extends spirally in the first direction; wherein, the first transmission unit 4311 cooperates with the second transmission unit 4331 to drive the intermediate wheel 433 to rotate forward when the drive wheel 431 rotates forward, and moves towards the transmission wheel 432 to the point where the third transmission unit 4334 and the fourth transmission unit 4321 cooperate, thereby driving the transmission wheel 432 to rotate forward; when the drive wheel 431 rotates in reverse, the third transmission unit 4334 separates from the fourth transmission unit 4321.
[0092] It should be noted that the forward rotation direction can be either clockwise or counterclockwise rotation of the drive unit 401. The forward rotation direction in this application is only a unified direction and does not represent a specific clockwise or counterclockwise rotation.
[0093] Referring to Figures 9 and 10, when the drive wheel 431 rotates clockwise, the first transmission part 4311 cooperates with the second transmission part 4331, causing the intermediate wheel 433 to move towards the transmission wheel 432. This, in turn, causes the third transmission part 4334 to cooperate with the fourth transmission part 4321. That is, the intermediate wheel 433 drives the transmission wheel 432 to rotate, and the drive part 401 drives the second transmission mechanism 470 to move. When the drive wheel 431 rotates counterclockwise, under the action of the third transmission part 4334 and the fourth transmission part 4321, the intermediate wheel 433 moves towards the drive wheel 431 until the third transmission part 4334 separates from the fourth transmission part 4321 or the third transmission part 4334 and the fourth transmission part 4321 are only in contact without transmission. In this case, the second transmission mechanism 470 is not driven by the drive part 401, that is, the drive part 401 does not drive the cleaning component 10 to move. The cooperation between the first transmission unit 4311 and the second transmission unit 4331, and the cooperation between the third transmission unit 4334 and the fourth transmission unit 4321, enables the drive unit 401 to rotate forward and drive the second transmission mechanism 470 to move. When the drive unit 401 rotates in reverse, it does not drive the second transmission mechanism 470 to move. The control is convenient, simple and effective.
[0094] Referring to Figure 9, in one embodiment, the first transmission part 4311 includes a first rib 4312. The first rib 4312 is disposed on the side of the drive wheel 431 facing the intermediate wheel 433. The first rib 4312 is inclined away from the intermediate wheel 433 in the forward rotation direction. In other words, the rear side of the first rib 4312 in the forward rotation direction is closer to the intermediate wheel 433 than the front side. When the drive wheel 431 rotates forward, the second transmission part 4331 cooperates with the first transmission part 4311. Moving along the surface of the first rib 4312, since the drive wheel 431 does not move horizontally, the translation component applied by the first rib 4312 to the second transmission part 4331 causes the intermediate wheel 433 to move away from the drive wheel 431, that is, the intermediate wheel 433 moves closer to the transmission wheel 432, so that the third transmission part 4334 cooperates with the fourth transmission part 4321, and the third transmission part 4334 drives the fourth transmission part 4321 to rotate, that is, the intermediate wheel 433 drives the transmission wheel 432 to rotate in the same direction.
[0095] Referring to Figure 9, in one embodiment, the first transmission part 4311 includes a first limiting block 4313. The first limiting block 4313 cooperates with the second transmission part 4331 to cause the drive wheel 431 to drive the intermediate wheel 433 to rotate. The first protruding rib 4312 is mainly used to apply a translational component to the second transmission part 4331 so that the intermediate wheel 433 and the drive wheel 431 move horizontally. The first limiting block 4313 is mainly used to limit the second transmission part 4331 so that the first limiting block 4313 drives the second transmission part 4331 to rotate in the same direction, that is, the drive part 401 drives the intermediate wheel 433 to rotate in the same direction. Through the combined action of the first protruding rib 4312 and the first limiting block 4313, the drive wheel 431 can both drive the intermediate wheel 433 to rotate and, when the drive wheel 431 rotates forward, cause the intermediate wheel 433 to move away from the drive wheel 431.
[0096] Referring to Figure 9, in one embodiment, the end of the first limiting block 4313 near the intermediate wheel 433 extends beyond the end of the first rib 4312 near the intermediate wheel 433. In other words, the first limiting block 4313 is deeper into the intermediate wheel 433 than the first rib 4312, so that when the second transmission part 4331 moves to the end of the first rib 4312, the first limiting block 4313 restricts the second transmission part 4331 from continuing to rotate relative to the first rib 4312, so that the drive part 401 can drive the intermediate wheel 433 to rotate.
[0097] Please refer to Figures 10 and 11. In one embodiment, the second transmission part 4331 includes a second rib 4332. The second rib 4332 is disposed on the side of the intermediate wheel 433 facing the drive wheel 431. The second rib 4332 is inclined towards the drive wheel 431 in the forward rotation direction. In other words, the rear side of the second rib 4332 in the reverse rotation direction is closer to the drive wheel 431 than the front side. Since the second rib 4332 is disposed facing the drive wheel 431, when the drive wheel 431 rotates forward, the second rib 4332 rotates in reverse relative to the drive wheel 431. The first transmission part 4311 moves along the surface of the second rib 4332, and the intermediate wheel 433 moves away from the drive wheel 431. That is, the intermediate wheel 433 moves away from the drive wheel 431 and approaches the transmission wheel 432, so that the third transmission part 4334 cooperates with the fourth transmission part 4321, and the intermediate wheel 433 drives the transmission wheel 432 to rotate.
[0098] Referring to Figure 10, in one embodiment, the second transmission part 4331 includes a second limiting block 4333. The second limiting block 4333 cooperates with the first transmission part 4311 to cause the drive wheel 431 to drive the intermediate wheel 433 to rotate. The second protruding rib 4332 is mainly used to cooperate with the first transmission part 4311, so that the first transmission part 4311 applies a translational component to the second transmission part 4331 to cause the intermediate wheel 433 and the drive wheel 431 to move horizontally. The second limiting block 4333 is mainly used to limit the first transmission part 4311, so that the first transmission part 4311 drives the second limiting block 4333 to rotate in the same direction, that is, the drive wheel 431 drives the intermediate wheel 433 to rotate in the same direction. Through the combined action of the second protruding rib 4332 and the second limiting block 4333, the drive wheel 431 can both drive the intermediate wheel 433 to rotate and, when the drive wheel 431 rotates forward, cause the intermediate wheel 433 to move away from the drive wheel 431.
[0099] Referring to Figure 10, in one embodiment, the end of the second limiting block 4333 near the drive wheel 431 extends beyond the end of the second rib 4332 near the drive wheel 431. In other words, the second limiting block 4333 extends deeper into the drive wheel 431 than the second rib 4332, so that when the first transmission part 4311 moves to the end of the second rib 4332, the second limiting block 4333 restricts the first transmission part 4311 and the second rib 4332 from continuing to move relative to each other, so that the drive wheel 431 can drive the intermediate wheel 433 to rotate.
[0100] Referring to Figures 9 and 10, in one embodiment, the first transmission part 4311 includes a first rib 4312 and a first limiting block 4313, and the second transmission part 4331 includes a second rib 4332 and a second limiting block 4333. The first rib 4312 and the second rib 4332 cooperate, with the inclined surface of the first rib 4312 near the intermediate wheel 433 abutting against the inclined surface of the second rib 4332 near the drive wheel 431. This allows the first rib 4312 to apply a horizontal component to the second rib 4332 when the drive wheel 431 rotates forward, driving the intermediate wheel 433 to move towards the transmission wheel 432. The first limiting block 4313 cooperates with the second limiting block 4333, causing the drive wheel 431 to drive the intermediate wheel 433 to rotate.
[0101] In one embodiment, the first limiting block 4313 extends between the second limiting block 4333 and the second protruding rib 4332, and the first limiting block 4313 can rotate relative to the intermediate wheel 433 between the second limiting block 4333 and the second protruding rib 4332. When the drive wheel 431 rotates clockwise, the first limiting block 4313 presses against the second limiting block 4333, so that the drive unit 401 drives the intermediate wheel 433 to rotate in the same direction; when the drive wheel 431 rotates counterclockwise, the first limiting block 4313 presses against the end wall of the second protruding rib 4332, so that the drive wheel 431 drives the intermediate wheel 433 to rotate counterclockwise.
[0102] Furthermore, the second limiting block 4333 extends between the first limiting block 4313 and the second protruding rib 4332, and the second limiting block 4333 can rotate relative to the drive wheel 431 between the first limiting block 4313 and the second protruding rib 4332.
[0103] In one embodiment, multiple first limiting blocks 4313 and multiple first protruding ribs 4312 are respectively provided. The multiple first limiting blocks 4313 are arranged circumferentially along the drive wheel 431, and the multiple first protruding ribs 4312 are arranged circumferentially along the drive wheel 431. Multiple second limiting blocks 4333 and multiple second protruding ribs 4332 are respectively provided. The multiple second limiting blocks 4333 are arranged circumferentially along the intermediate wheel 433, and the multiple second protruding ribs 4332 are arranged circumferentially along the intermediate wheel 433, so as to balance the force on the drive wheel 431 and the intermediate wheel 433 and improve the service life of the drive wheel 431 and the intermediate wheel 433. The number of first limiting blocks 4313, first protruding ribs 4312, second limiting blocks 4333 and second protruding ribs 4332 are equal, for example, 2, 3, 4, etc.
[0104] Please refer to Figure 12. In one embodiment, a fourth transmission part 4321 extending spirally along a first direction is provided on the transmission wheel 432. The first direction is from the transmission wheel 432 to the intermediate wheel 433. The fourth transmission part 4321 is inclined towards the intermediate wheel 433 in the reverse direction. As shown in Figure 11, the third transmission part 4334 is inclined towards the transmission wheel 432 in the forward rotation direction. When the third transmission part 4334 rotates forward, the end wall of the third transmission part 4334 abuts against the end wall of the fourth transmission part 4321, thereby causing the third transmission part 4334 to drive the fourth transmission part 4321 to rotate in the same direction. When the fourth transmission part 4321 or the third transmission part 4334 rotates in reverse, the inclined surface of the fourth transmission part 4321 near the intermediate wheel 433 abuts against the inclined surface of the third transmission part 4334 near the transmission wheel 432, causing the intermediate wheel 433 to move away from the transmission wheel 432. The intermediate wheel 433 and the transmission wheel 432 do not drive each other, that is, the drive part 401 does not drive the second transmission mechanism 470 to move.
[0105] In one embodiment, multiple third transmission parts 4334 and fourth transmission parts 4321 are provided, and the number of third transmission parts 4334 and fourth transmission parts 4321 is equal, which can be 2, 3, 4, 5, etc., to balance the force on the intermediate wheel 433 and the transmission wheel 432, improve the stability of the intermediate wheel 433 and the transmission wheel 432 when rotating, and extend the service life of the intermediate wheel 433 and the transmission wheel 432.
[0106] Referring to Figures 5 and 6, in one embodiment, the second transmission mechanism 470 includes a reel 471 and a traction member 472. The reel 471 is connected to a clutch member 430 so that when the drive unit 401 is connected to the second transmission mechanism 470, the drive unit 401 drives the reel 471 to rotate; one end of the traction member 472 is fixed to the reel 471, and the other end is fixed to the main body of the cleaning device 1 or the cleaning component 700, so that when the reel 471 rotates, it drives the cleaning component 700 to move between a third position and a fourth position.
[0107] One end of the traction member 472 is fixed to the reel 471, and the other end is fixed to the main body of the cleaning device 1. When the reel 471 rotates, the traction member 472 winds around the reel 471, thereby driving the cleaning component 10 to move relative to the main body of the cleaning device 1. When the clutch member 430 controls the drive unit 401 to disconnect from the second transmission mechanism 470, under the action of gravity, the cleaning component 10 moves downward and drives the traction member 472 to move, which in turn drives the reel 471 to rotate until the cleaning component 10 moves to the point where the traction member 472 is fully open and no longer winds around the reel 471 or other limited positions, at which point the cleaning component 10 stops moving. The cleaning component 700 moves to the fourth position, i.e., the descending position, by gravity, and moves to the third position, i.e., the retracted position, driven by the traction member 472. The drive unit 401 only needs to drive the cleaning component 10 to move in the forward direction. When the drive unit 401 reverses, it only drives the first transmission mechanism 410 to work, which expands the application of the drive unit 401, reduces the number of drive units 401, and reduces costs.
[0108] When one end of the traction member 472 is fixed to the reel 471 and the other end is fixed to the cleaning member 700, the traction member 472 winds around the reel 471 when the reel 471 rotates, thereby driving the cleaning member 700 to move relative to the housing 100 of the cleaning assembly 10. When the clutch member 430 controls the drive unit 401 to disconnect from the second transmission mechanism 470, the cleaning member 700 moves downward under the gravity of the cleaning member 700 and drives the traction member 472 to move, thereby driving the reel 471 to rotate until the cleaning member 700 moves to the point where the traction member 472 is fully open and not winds around the reel 471 or other limited positions, the cleaning member 700 stops moving, thereby completing the movement of the cleaning member 700 relative to the cleaning device 1 between the third position and the fourth position.
[0109] In one embodiment, the spool 471 is fixed to the drive wheel 432 of the clutch 430. The fixing method includes, but is not limited to, integral molding, welding connection, adhesive connection, and bolt connection. Preferably, the spool 471 and the clutch 430 are integrally molded to reduce the number of assembly parts and improve the quality stability of the components.
[0110] In one embodiment, the first lifting member 200 is a component that moves relative to the housing 100. For example, the first lifting member 200 can be a baffle disposed at the front of the housing 100 to block part of the air intake channel of the suction port 141. When the first lifting member 200 is in the second position, it covers part of 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. When the first lifting member 200 is in the second position, the ventilation area of the front side of the suction port 141 is reduced, which increases the air velocity and pressure of the suction port while keeping the suction force unchanged. This effectively improves the adsorption capacity for dust, hair, etc., and meets the usage needs of the cleaning component 10 in different scenarios.
[0111] A first cover plate 110 is provided on the front side of the housing 100. The first cover plate and the housing surface form a first limiting groove. The first lifting member 200 is at least partially disposed in the first limiting groove and moves along the first limiting groove. On the one hand, the first cover plate protects the first lifting member and reduces the risk of the first lifting member being damaged by impact. On the other hand, the first limiting groove formed between the first cover plate and the housing accommodates the sliding of the first lifting member, so that the first lifting member moves along a predetermined trajectory between a first position and a second position, avoiding interference with other components during the movement of the first lifting member.
[0112] In another embodiment, the first lifting member 200 may also be a scraper strip disposed at the rear of the housing 100 for scraping dust and particles from the surface being cleaned; the first lifting member 200 may also be a scraper blade for scraping dirt off the surface of the roller brush module 600.
[0113] Of course, as some possible approaches, the first lifting member 200 can also be other components that move relative to the housing 100 to achieve different functions of the cleaning assembly 10 and expand the application scenarios of the cleaning device 1. Referring to Figures 1 and 4, 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 can be a baffle for blocking a portion of the air intake channel 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 can be a baffle for blocking a portion of the air intake channel at the suction port 141, and the baffle is rotatably disposed on the housing 100, rotating around the baffle's rotation axis 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.
[0114] The drive unit 401 includes, but is not limited to, a motor, which drives the first transmission mechanism 410 and the second transmission mechanism 470 to move along a predetermined trajectory. Preferably, the drive unit 401 is a motor. The output shaft of the motor can be directly connected to the first transmission mechanism 410 and / or the clutch 430, 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 transmission mechanism 410 and / or the clutch 430.
[0115] Referring to Figures 5 and 14, in one embodiment, the first transmission mechanism 410 includes a first driving member 411 and a first driven member 412. The first driving member 411 is connected to the drive unit 401; the first driven member 412 is rotatably mounted on the first driving member 411 and rotatably connected to the first lifting member 200. Through the combined action of the first driving member 411 and the first driven member 412, the first lifting member 200 is driven to move between a first position and a second position. The movement trajectory is stable and controllable, facilitating structural design.
[0116] In one embodiment, the clutch 430 is fixed relative to the first driving member 411, so that the clutch 430 is connected to the drive unit 401. The relative fixing of the clutch 430 and the first driving member 411 facilitates the arrangement of the second transmission mechanism 470 and the first transmission mechanism 410 along the axial direction of the drive unit 401, making full use of the space along the length of the cleaning assembly 10 and simplifying the structural layout of the cleaning assembly 10. The clutch 430 and the first driving member 411 can be directly fixed together, or they can be fixed together with other components at intervals, so as to achieve synchronous rotation of the first driving member 411 and the clutch 430.
[0117] Referring to Figures 14 and 15, in one embodiment, the first driving member 411 has a wheel-like structure, and the first driven member 412 is rotatably disposed at the eccentric position of the first driving member 411. The wheel-like structure can effectively balance the force on the drive unit 401, reduce the shear force on the drive unit 401, reduce the risk of damage to the drive unit 401, and improve the service life of the drive unit 401.
[0118] Referring to Figures 4 and 14, in one embodiment, the cleaning assembly 10 includes a third transmission mechanism 420 and a second lifting member 300. The third transmission mechanism 420 is connected to the first transmission mechanism 410; the second lifting member 300 is disposed on the housing 100, and the second lifting member 300 has at least a fifth position and a sixth position relative to the housing 100. The third transmission mechanism 420 drives the second lifting member 300 to move between the fifth position and the sixth position. By adding the third transmission mechanism 420, the movement of the second lifting member 300 can be realized, thereby enabling the lifting drive unit 401 of the cleaning assembly 10 to drive the movement of multiple lifting members, realizing the multi-purpose function of the drive unit 401, expanding the application range of the drive unit 401, reducing the number of required drive units 401, reducing costs, and facilitating structural layout.
[0119] In one embodiment, with the forward direction of the cleaning device 1 as the front side, the second lifting member 300 in the sixth position is located behind the suction port 141 and abuts against the surface to be cleaned. When the second lifting member 300 is in the sixth position, it can scrape away dust, debris, etc. that have not yet been cleaned, thereby reducing the situation where dust and debris remain on the surface to be cleaned after the cleaning component 10 moves, and improving the cleaning ability of the cleaning component 10.
[0120] In one embodiment, the part of the second lifting member 300 that abuts against the surface to be cleaned is a flexible part, and the second lifting member 300 at the sixth position has a first interference fit with the surface to be cleaned, so that the second lifting member 300 is close to the surface to be cleaned, thereby 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.
[0121] Referring to Figure 14, in one embodiment, the third transmission mechanism 420 includes a third driving member 421 and a third driven member 422. The third driving member 421 is fixed to the first driving member 411; the third driven member 422 is rotatably disposed on the third driving member 421 and rotatably connected to the second lifting member 300. Through the third driving member 421 and the third driven member 422, the driving unit 401 can drive the second lifting member 300 to move between the fifth position and the sixth position. By fixing the third driving member 421 to the first driving member 411 and rotating synchronously with the first driving member 411, the driving unit 401 can simultaneously drive the first driving member 411 and the second driving member to move, thereby driving the first lifting member 200 and the second lifting member 300 to move simultaneously.
[0122] Referring to Figure 15, in one embodiment, the first transmission mechanism 410 includes a first rotating shaft 413 fixedly mounted on the first driving member 411, a first driven member 412 rotating around the first rotating shaft 413 and rotating with the first driving member 411, and a third driving member 421 fixed to the first driving member 411 via the first rotating shaft 413. The rotation of the first driven member 412 around the first rotating shaft 413 and the fixed connection between the third driving member 421 and the first driving member 411 via the first rotating shaft 413 prevents collisions or interference between the first driven member 412 and the third driving member 421 during rotation.
[0123] Referring to Figure 15, in one embodiment, the cleaning assembly 10 includes a support wheel 440, which is rotatably mounted on the housing 100. A second rotating shaft 423 is provided on the third driving member 421, and a third driven member 422 is rotatably connected to the third driving member 421 around the second rotating shaft 423. The support wheel 440 is fixed to the third driving member 421 via the second rotating shaft 423, effectively preventing interference between the third driven member 422 and the support wheel 440 during rotation, and facilitating the path design of the third driven member 422. The support wheel 440 can support the first transmission mechanism 410, etc., reducing the force on the drive unit 401 and lowering the risk of damage to the drive unit 401.
[0124] Referring to Figure 5, in one embodiment, the cleaning assembly 10 includes a detection module 500. The detection module 500 is configured to detect the rotational position of the first active member 411 to obtain the position of the first lifting member 200. By detecting the rotational position of the first active member 411, the detection module 500 can obtain the position of the first lifting member 200, allowing the first lifting member 200 to move accurately to the desired position.
[0125] In one embodiment, the detection module 500 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 twice 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, while the other is fixed relative to the housing. When the first active member rotates to a preset position, the detection element triggers the detector to monitor the rotation angle of the first active member. When the first active member rotates to the expected position, the drive unit is controlled to stop the first active member, thereby stopping the first lifting member at the expected position.
[0126] Referring to Figure 17, 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 the first detection element 510 is provided with at least one first detection area 511; the first detector 520 is fixed relative to the housing 100, and the first detector 520 is triggered when the first detection area 511 rotates to the first detector 520; the second detection element 530 is fixed relative to the first active element 411, and the second detection element 530 is provided with at least one second detection area 531; the second detector 540 is fixed relative to the housing 100, and the second detector 540 is triggered when the second detection area 531 rotates to the second detector 540. The first active member 411 has at least two preset angles that can trigger the first detector 520 and / or the second detector 540. For example, the two preset angles can trigger the first detector 520 and the second detector 540 respectively, or one of the two preset angles can trigger the first detector 520 and the second detector 540 simultaneously, while the other preset angle can trigger either the first detector 520 or 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 based on the rotation angle of the first active member 411, and then controlling the start and stop of the drive unit 401 to keep the first lifting member 200 at the expected position. For example, the first detector 520 and the second detector 540 are triggered by two preset angles respectively. When the first detector 520 is triggered, it indicates that the first lifting member 200 is in the first position, and when the second detector 540 is triggered, it indicates that the first lifting member 200 is in the second position. Alternatively, the first detector 520 and the second detector 540 are triggered by one of the two preset angles at the same time. In this case, it indicates that the first lifting member 200 is in the first position. When the first detector 520 or the second detector 540 is triggered by the other preset angle, it indicates that the first lifting member 200 is in the second position.
[0127] In one embodiment, the first active member 411 has at least three preset rotation angles that can trigger the first detector 520 and / or 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 meet the functional requirements of the first lifting member 200 and the second lifting member 300.
[0128] Referring to Figure 17, 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 401 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 component 10 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 401. 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 401 continues to work to drive the first active member 411 to rotate to the trigger angle of the second detector 540 once or twice, and then controls the drive unit 401 to stop, so that the first lifting member 200 and the second lifting member 300 move to the expected position.
[0129] 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.
[0130] 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 401.
[0131] 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.
[0132] 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.
[0133] 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.
[0134] Referring to the figure, 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 401 is more uniform, reducing the radial shear force on the drive unit 401 and improving the service life of the drive unit 401. The through detection holes and optical couplers make it easier to trigger the detectors, which is convenient to implement and has a lower cost.
[0135] 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 401. Of course, the disc-type detection component may also be exempt from weight reduction.
[0136] In one embodiment, the detection module 500 is triggered when the first active member 411 rotates to the third preset angle. When the first active member 411 moves the cleaning member 700 from the fourth position to the third position from the third preset angle, the first lifting member 200 rises to the first position. The detection module 500 is triggered when the first active member 411 rotates to the third preset angle. When the first active member 411 starts moving from the third preset angle and moves the cleaning member 700 from the fourth position to the third position, the first lifting member 200 rises to the first position. That is, when the cleaning member 700 rises, the first lifting member 200 rises simultaneously, facilitating the movement of the cleaning device 1.
[0137] In one embodiment, the drive unit 401 includes a motor; the rotation angle by which the motor drives the cleaning component 700 to move from the fourth position to the third position is the first stroke, and the rotation angle by which the motor drives the first lifting component 200 between the first position and the second position is the second stroke, the second stroke being an integer multiple of the first stroke. When the drive unit 401 rotates forward, it can drive the first transmission mechanism 410 and the second transmission mechanism 470; when it rotates in reverse, it only drives the second transmission mechanism 470, adjusting the second stroke to an integer multiple of the first stroke. When the cleaning component 700 needs to be raised to the third position, the first lifting component 200 is first moved to the first position or the second position, and then the drive unit 401 rotates forward to drive the first lifting component 200 and the cleaning component 700 to move, so that when the cleaning component 700 is raised to the third position, the first lifting component 200 moves to the retracted first position, so that when the cleaning component 700 is retracted, the first lifting component 200 is also retracted. When the cleaning component 700 does not require height adjustment, the drive unit 401 reverses the drive of the first transmission mechanism 410 to adjust the position of the first lifting component 200.
[0138] This application controls the connection between the drive unit 401 and the second transmission mechanism 470 via a clutch 430. When the cleaning component 700 does not need to be raised or lowered, the clutch 430 controls the drive unit 401 to disconnect from the second transmission mechanism 470. The drive unit 401 then independently drives the first transmission mechanism 410 to move the first lifting component 200. The first lifting component 200 utilizes the drive unit 401 that raises and lowers the cleaning component 700, effectively reducing the number of drive units 401, lowering costs, and facilitating the spatial layout of the cleaning assembly 10. Therefore, this application effectively overcomes some practical problems in the prior art, thus having high utilization value and practical significance.

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.
