DETAILED DESCRIPTION

[0111] It should be noted that, unless there is a conflict, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of this application and should not be regarded as an improper restriction on this application.

[0112] In the following description, the terms "first\second\..." are merely used to distinguish different objects and do not imply that the objects are identical or connected.

[0113] It should be noted that the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus comprising that element. "A plurality" means greater than or equal to two.

[0114] The cleaning device of the embodiment of the present application includes a device body and a cleaning device. The cleaning device is installed on the device body. The cleaning device includes a cleaning member. The device body or the cleaning device drives the cleaning member to move to clean the surface to be cleaned.

[0115] In the embodiment of the present application, the cleaning member is driven to move by the equipment body or the cleaning device, so that the cleaning member can automatically clean the surface to be cleaned, which helps to relieve the operator from repeatedly moving the cleaning member to clean the surface to be cleaned and can effectively reduce labor intensity.

[0116] In one embodiment, the cleaning member moves between a first position and a second position, the second position being farther from the center of the device body than the first position.

[0117] In the embodiment of the present application, since the second position is farther from the center of the device body than the first position, the cleaning member is moved to the second position farther from the center of the device body by switching the position of the cleaning member relative to the device body, so that the cleaning member can be closer to the side area relative to the device body, thereby being able to better clean the difficult-to-clean areas on the side of the device body.

[0118] First embodiment:

[0119] In the description of the embodiments of the present application, "up", "down", "top", "bottom", orientation or position relationship is based on the orientation or position relationship shown in the accompanying drawings. It should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0120] In the related art, the corresponding driving mechanism drives the cleaning member to rotate around the fixed axis so that the cleaning member cleans the floor, that is, the rotation centerline of the cleaning member cannot move. When the cleaning device moves along the edge (for example, along the wall) to clean the floor, the body component is spaced a certain distance from the target edge (for example, the wall, the edge of furniture). Since the rotation centerline of the cleaning member cannot move, the cleaning member may be spaced a certain distance from the target edge, making it difficult for the cleaning member to clean positions near corners. Therefore, there may be blind spots in cleaning, and it is difficult for the cleaning member to clean positions near corners of the surface to be cleaned.

[0121] In view of this, an embodiment of the present application provides a cleaning device, which includes a device body and a cleaning device. The cleaning device is installed on the device body. The cleaning device includes a cleaning piece. The device body or the cleaning device drives the cleaning piece to move to clean the surface to be cleaned.

[0122] Please refer to Figures 1 to 5. The main body of the device includes a body component 1, a first drive device 2 and a transmission device 3. The first drive device 2 is installed on the body component 1. The transmission device 3 connects the first drive device 2 and the cleaning member 4, and the first drive device 2 drives the cleaning member 4 to rotate through the transmission device 3. During the rotation of the cleaning member 4, the force generated by the rotation of the cleaning member 4 drives the cleaning member 4 to move from the first position to the second position. With such a structural form, the cleaning member 4 of the present application is driven by the first drive device 2 so that the cleaning member 4 can move to the second position according to actual needs. When the cleaning device is in the edge mode, it is necessary to clean the corner position close to the target edge 9. The transmission device 3 is driven by the first drive device 2 to drive the cleaning member 4 to rotate. The force generated by the rotation of the cleaning member 4 drives the cleaning member 4 to move from the first position to the second position, thereby facilitating the cleaning of the corner position of the target edge 9 and reducing the cleaning blind spot, so that the surface to be cleaned can be better cleaned as much as possible.

[0123] It should be noted that the force generated by the rotation of the cleaning member 4 is mainly the friction generated by the contact between the cleaning member 4 and the surface to be cleaned during the rotation process. This friction force reacts on the cleaning member 4 to form a counter torque opposite to the rotation direction of the cleaning member 4.

[0124] It should be explained that the cleaning member 4 is used to clean the surface to be cleaned, and the surface to be cleaned here is the surface to be cleaned of the object to be cleaned.

[0125] Exemplarily, the first drive device 2 is partially connected to the fuselage component 1 , so that the first drive device can be fixedly mounted on the fuselage component.

[0126] In one embodiment, referring to Figures 1 to 5, the device body further includes a reset member 5, which is connected to the cleaning member 4 and / or the transmission device 3. The force generated by the reset member 5 drives the cleaning member 4 to move from the second position to the first position.

[0127] In the embodiment of the present application, the cleaning member 4 is reset by the force generated by the reset member 5 , so that the cleaning member 4 can be reset from the second position to the first position, so as to better clean the main area under the fuselage assembly 1 .

[0128] In one embodiment, referring to Figures 3 to 6 , the transmission device 3 includes a transmission body 31, and an input shaft 32 and an output shaft 33 connected to the transmission body 31. With this structure, the transmission body 31 receives power input from the first drive device 2 via the input shaft 32, causing the input shaft 32 to rotate. During the rotation of the input shaft 32, the transmission body 31 transmits the rotational motion of the input shaft 32 to the output shaft 33, causing the output shaft 33 to rotate relative to the transmission body 31. The output shaft 33 then transmits power to the cleaning element 4, causing the cleaning element 4 to rotate, thereby cleaning the surface to be cleaned.

[0129] It should be noted that both the input shaft 32 and the output shaft 33 are rotatable relative to at least a portion of the structure of the transmission body 31 .

[0130] It is understandable that the specific structure of the transmission device 3 is not limited, as long as it can transmit the power of the first driving device 2 to the cleaning member 4, so that the cleaning member 4 moves to clean the surface to be cleaned.

[0131] In one embodiment, referring to Figures 3-6 , an input shaft 32 is rotationally connected to the body assembly 1. A first drive device 2 is used to drive the input shaft 32 to rotate, thereby causing the output shaft 33 to rotate accordingly. The cleaning member 4 is connected to the output shaft 33 to rotate with the output shaft 33. With this structure, the input shaft 32 is rotationally connected to the body assembly 1 and rotates along a fixed axis relative to the body assembly 1. That is, the central axis of the input shaft 32 barely moves relative to the body assembly 1. The rotation of the input shaft 32 driven by the first drive device 2 drives the output shaft 33 to rotate accordingly via the transmission body 31, thereby driving the cleaning member 4 connected to the output shaft 33 to rotate.

[0132] It is understandable that the connection relationship between the input shaft 32 and the output shaft 33 is not limited, as long as the first drive device 2 can drive the input shaft 32 to drive the output shaft 33 to rotate, and then the output shaft 33 can drive the cleaning member 4 to rotate.

[0133] In one embodiment, referring to Figures 3 to 5 , the transmission device 3 and the cleaning member 4 are integrally formed and are capable of rotating about the input shaft 32. With this structure, the cleaning member 4 rotates about the input shaft 32, and the position of the first drive device 2 is minimally affected by the cleaning member 4 during movement from the first position to the second position.

[0134] It can be understood that in the process of the force generated by the rotation of the cleaning member 4 driving the cleaning member 4 to move from the first position to the second position, the cleaning member 4, the output shaft 33 and the transmission body 31 rotate around the input shaft 32 as a whole. Since the input shaft 32 is rotationally connected to the fuselage assembly 1, the cleaning member 4, the output shaft 33 and the transmission body 31 rotate around the input shaft 32 as a whole. The corresponding mounting position of the first drive device 2 on the fuselage assembly 1 can basically remain unchanged, which is convenient for the installation of the first drive device 2. The wiring required for power supply, etc. connected to the first drive device 2 does not need to move with the first drive device 2, which is also convenient for the wiring required for power supply, etc. of the first drive device 2.

[0135] In one embodiment, referring to FIG. 3 to FIG. 6 , the input shaft 32 and the output shaft 33 are eccentrically arranged.

[0136] In one embodiment, please refer to Figures 1 to 5, the cleaning member 4 is used to clean the surface to be cleaned of the object to be cleaned, and the transmission device 3 and the cleaning member 4 as a whole can rotate around the input shaft 32 to switch between the second position and the first position. The number of cleaning members 4 is one or at least two, wherein the edge of the body component 1 along the preset direction toward the side corresponding to the cleaning member 4 is the preset edge 10, and the preset direction is perpendicular to the moving direction and the up and down direction of the body component 1 respectively, and the second position is located on the side of the first position along the preset direction toward the corresponding preset edge 10.

[0137] It should be noted that when the cleaning device needs to clean corners near the target edge 9, the cleaning member 4 switches from the first position to the second position under the action of the reaction torque exerted by the surface of the object to be cleaned, and the cleaning member 4 accordingly extends from the body assembly 1, and the cleaning member 4 extends further outside the outline of the body assembly 1. When the cleaning device no longer needs to clean corners near the target edge 9, the cleaning member 4 can be retracted from the second position to the first position.

[0138] It should be noted that the second position is located on the side of the first position along the preset direction toward the corresponding preset edge 10. The cleaning member 4 located at the first position is closer to the middle position of the fuselage assembly 1 in the preset direction, and the cleaning member 4 located at the second position can extend further out of the fuselage assembly 1 along the preset direction.

[0139] Exemplarily, the transmission body 31 is a reduction gearbox.

[0140] For example, referring to FIG. 6 , the up and down directions are the directions indicated by arrows R1 in the figure.

[0141] Exemplarily, referring to FIG. 1 and FIG. 2 , the preset direction is the direction indicated by the arrow R2 in the figures.

[0142] For example, referring to FIG. 1 and FIG. 2 , the moving direction of the fuselage assembly 1 is the direction indicated by the arrow R4 in the figures.

[0143] For example, when the cleaning member 4 is separated from the surface to be cleaned, the cleaning member 4 is no longer affected by the counter torque of the surface to be cleaned, and the cleaning member 4 can be switched from the second position back to the first position.

[0144] For example, please refer to FIG. 1 , which shows that both the left and right cleaning members 4 are located in the first position.

[0145] For example, referring to FIG. 2 , the left cleaning member 4 is shown in the first position, and the right cleaning member 4 is shown in the second position.

[0146] For example, referring to FIG. 6 , the input shaft 32 is parallel to the output shaft 33 .

[0147] It should be noted that the input shaft 32 and the output shaft 33 are eccentrically arranged, that is, the input shaft 32 and the output shaft 33 are spaced apart by a certain distance along the radial direction of the input shaft 32 .

[0148] For example, the surface to be cleaned may be the ground, and the supporting surface of the object to be cleaned is the surface to be cleaned on the ground.

[0149] Exemplarily, the cleaning device is a mop.

[0150] Exemplarily, the cleaning member 4 is a mop tray provided with a rag.

[0151] Exemplarily, the cleaning member 4 may also be a side brush, a roller brush or other possible cleaning members.

[0152] In one embodiment, referring to FIG3 , the first drive device 2 is located on one side of the input shaft 32 along the radial direction of the input shaft 32. With this structure, the first drive device 2 drives the input shaft 32 from one side of the radial direction of the input shaft 32, allowing both ends of the input shaft 32 to be easily rotatably connected to the fuselage assembly 1 to achieve fixed-axis rotation of the input shaft 32.

[0153] It is understandable that the installation position of the first driving device is not limited. Exemplarily, the first driving device 2 is drivingly connected to one end of the input shaft 32 to drive the input shaft 32 to rotate.

[0154] In one embodiment, referring to FIG3 , the first drive device 2 includes a driver 21, a first transmission wheel 23, a second transmission wheel 24, and a worm 22. The driver 21 is mounted on the body assembly 1. The first transmission wheel 23 is rotationally connected to the body assembly 1. The second transmission wheel 24 is sleeved on the input shaft 32 and rotates with the input shaft 32. The worm 22 is mounted on the driver 21 so that the driver 21 drives the worm 22 to rotate. The worm 22 meshes with the first transmission wheel 23, and the first transmission wheel 23 meshes with the second transmission wheel 24. With this structural form, the first transmission wheel 23 is rotationally connected to the body assembly 1, rotates on a fixed axis, and the rotation center axis of the first transmission wheel 23 remains substantially unchanged relative to the body assembly 1. The worm 22 is driven to rotate by the driver 21, thereby rotating the first transmission wheel 23 and the second transmission wheel 24 that are meshed in sequence. The rotating second transmission wheel 24 drives the input shaft 32 to rotate. The two ends of the input shaft 32 do not need to receive kinetic energy input, so that the input shaft 32 can be more conveniently connected to the fuselage assembly 1 for rotation, and it is beneficial to reduce the axial size of the cleaning equipment along the input shaft 32.

[0155] Exemplarily, the driver 21 may be a motor.

[0156] Exemplarily, the first transmission wheel 23 and the second transmission wheel 24 are both helical gears.

[0157] For example, the input shaft 32 may be directly driven to rotate by the driver 21 .

[0158] For example, referring to FIG. 1 , FIG. 2 , FIG. 4 and FIG. 5 , the rotation direction of the cleaning member 4 is the direction indicated by the arrow R3 in the figures.

[0159] For example, referring to FIG. 4 and FIG. 5 , the reaction torque applied by the surface to be cleaned to the cleaning member 4 is M, and the direction indicated by the arrow corresponding to the reaction torque M in the figure is the direction of the reaction torque M.

[0160] It is understandable that the number of the cleaning members 4 is not limited. For example, the number of the cleaning members 4 may be one or at least two.

[0161] For example, referring to FIG. 1 and FIG. 2 , the number of the cleaning members may be at least two, and the at least two cleaning members may contact the surface to be cleaned one by one so that the corresponding cleaning members can switch between the second position and the first position.

[0162] Exemplarily, referring to FIG. 1 and FIG. 2 , the number of the cleaning members may be at least two, and among the at least two cleaning members, all the cleaning members are in contact with the ground together so that all the cleaning members switch between the corresponding second position and the first position together.

[0163] In one embodiment, referring to Figures 1 and 2 , the vertical projection area of ​​the cleaning member 4 is a first area 41, the vertical projection area of ​​the body assembly 1 is a second area 11, and the extreme boundaries of the second area 11 on opposite sides of the preset direction are the target boundary 12. When the cleaning member 4 is in the second position, the first area 41 is arranged along the preset direction on both sides of the corresponding target boundary 12. When the cleaning member 4 is in the first position, the first area 41 is located on the side of the target boundary 12 facing the second area 11, and the cleaning member 4 is below the body assembly 1. With this structural form, the cleaning member 4 switches between the second position and the first position. In the second position, the first area 41 is arranged along the preset direction on both sides of the corresponding target boundary 12. When the cleaning member 4 cleans the corner near the target edge 9, the cleaning member 4 extends outside the body assembly 1 close to the target edge 9, allowing the cleaning member 4 to clean the surface to be cleaned as thoroughly as possible. When the cleaning member 4 is in the first position, the first area 41 is located on the side of the target boundary 12 facing the second area 11 , and the cleaning member 4 is stored below the body assembly 1 , so as to facilitate cleaning the path along which the body assembly 1 passes.

[0164] It should be noted that the first area 41 is arranged on both sides of the corresponding target boundary 12 along the preset direction, that is, the first area 41 is at least partially offset from the second area 11, and there is an area of ​​the first area 41 that does not overlap with the second area 11.

[0165] It can be understood that the boundary of the second area 11 along the preset direction generally does not exceed the target boundary 12 .

[0166] It is understood that when the cleaning member 4 is in the first position, the arrangement of the first region 41 and the second region 11 in the embodiment of the present application is not limited. For example, when the cleaning member 4 is in the first position, the first region 41 can be arranged along a preset direction across both sides of the corresponding target boundary 12, and the cleaning member 4 can be partially exposed laterally outside the fuselage assembly 1. When the cleaning member 4 is in the second position, the first region 41 corresponding to the cleaning member 4 further protrudes toward the side of the target boundary 12 away from the second region 11, and the cleaning member 4 is more laterally exposed from the fuselage assembly 1. The projected area of ​​the portion of the cleaning member 4 exposed laterally from the fuselage assembly 1 along the vertical direction is larger.

[0167] For example, referring to FIG1 , the cleaning member 4 is disengaged from the second position and returned to the first position, and the cleaning device is in a normal cleaning mode for the cleaning member 4. For example, if the cleaning device is generally cleaning an open floor, and the cleaning device body assembly 1 is far from the target edge 9, the cleaning member 4 can be disengaged from the second position and returned to the first position as needed, and the cleaning device is no longer in the edge cleaning mode.

[0168] For example, please refer to Figure 2, which shows that the right cleaning member 4 is in the second position, the first area 41 is arranged on both sides of the corresponding target boundary 12 along the preset direction, and the cleaning device is in the edge cleaning mode in which the cleaning member 4 cleans the corners near the target edge 9.

[0169] It should be noted that the outer side of the target boundary 12 is the side of the target boundary 12 facing away from the second area 11 .

[0170] In one embodiment, referring to Figures 1 and 2 , when cleaning member 4 is in the first position, the projected area of ​​the cleaning member 4's edge outside the projected area of ​​the edge of body assembly 1 is smaller than the area of ​​the cleaning member 4's edge outside the projected area of ​​the edge of body assembly 1 when cleaning member 4 is in the second position. With this structural form, cleaning member 4 in the second position is more exposed to the edge of body assembly 1 than cleaning member 4 in the first position, allowing cleaning member 4 in the second position to better clean the corners of target edge 9.

[0171] It is understood that the vertical projection area of ​​the cleaning member 4 in the second position and the vertical projection area of ​​the cleaning member 4 in the first position can both be located within the vertical projection area of ​​the body assembly 1. This is sufficient as long as the cleaning member 4 in the second position is closer to the edge of the body assembly 1 than the cleaning member 4 in the first position.

[0172] It is understandable that the projection area of ​​the cleaning member 4 in the second position along the vertical direction and the projection area of ​​the cleaning member 4 in the first position along the vertical direction may both be partially located outside the projection area of ​​the fuselage assembly 1 along the vertical direction.

[0173] In one embodiment, referring to Figures 3 and 4 , the body assembly 1 includes a second stopper 13. When the cleaning member 4 is in the second position, the second stopper 13 engages the transmission mechanism 3 to prevent the cleaning member 4 from moving due to the force generated by rotation. This structure maintains the cleaning member 4 in the second position as much as possible through the abutment between the second stopper 13 and the transmission mechanism 3, thereby preventing the cleaning member 4 from moving excessively outward due to the reaction torque of the surface to be cleaned.

[0174] Exemplarily, the second limiting portion 13 abuts against the transmission body 31 for limiting position.

[0175] Exemplarily, the second limiting portion 13 abuts against the output shaft 33 for limiting position.

[0176] It is understandable that the embodiment of the present application is not limited to limiting the transmission device 3 by the second limiting portion 13. For example, the transmission device 3 can be limited by the housing of the first driving device 2.

[0177] In one embodiment, referring to Figures 3 to 5 , the reset member 5 is an elastic member. With such a structure, the cleaning member 4 is reset by the elastic force of the elastic member.

[0178] It is understandable that the specific structural form of the reset member 5 is not limited. For example, the reset member 5 can be a structure with active reset power.

[0179] In one embodiment, referring to Figures 3 to 5, the cleaning member 4 is capable of moving in the vertical direction relative to the body assembly 1. When the cleaning member 4 contacts the surface to be cleaned, the force generated by the rotation of the cleaning member 4 drives the cleaning member 4 to overcome the elastic force of the elastic member and move from the first position to the second position. When the cleaning member 4 is disengaged from the surface to be cleaned, the cleaning member 4, which is in an upwardly lifted state relative to the body assembly 1, can move from the second position to the first position under the elastic force of the elastic member. With such a structural form, the cleaning member 4 can be raised and lowered in the vertical direction relative to the body assembly 1 to make the cleaning member 4 contact or disengage with the surface to be cleaned. The cleaning member 4 in contact with the surface to be cleaned overcomes the elastic force of the elastic member and moves to the second position under the action of the counter torque applied by the surface to be cleaned, so that the cleaning member 4 can better clean the corners near the target edge 9. When the corners near the target edge 9 are cleaned, the cleaning member 4 can be lifted upward relative to the body assembly 1 to disengage from the surface to be cleaned. The surface to be cleaned no longer applies a reaction torque to the cleaning member 4, and the transmission device 3 is reset from the second position to the first position under the action of the elastic force of the elastic member.

[0180] For example, referring to FIG. 3 to FIG. 5 , the reset member 5 is connected to the body assembly 1 and the transmission device 3 respectively.

[0181] Exemplarily, the restoring member 5 is connected to the body assembly 1 and the cleaning member 4 respectively.

[0182] For example, referring to Figures 3 to 5 , the force generated by the rotation of the cleaning member 4 drives the cleaning member 4 to rotate about the input shaft 32, overcoming the elastic force of the elastic member, so that the cleaning member 4 moves to the second position. For example, the reset member 5 may be a spring, an elastic cord, or other elastic material or structure, and is not specifically limited herein.

[0183] Exemplarily, the output shaft 33 is a telescopic shaft, and the extension and retraction of the output shaft 33 drives the cleaning member 4 to move in the vertical direction relative to the body assembly 1. For example, when the cleaning member 4 is needed for cleaning, the output shaft 33 is extended and locked, so that the cleaning member 4 disposed on the output shaft 33 contacts the surface to be cleaned. After cleaning is completed, the output shaft 33 can be retracted and locked, so that the cleaning member 4 disposed on the output shaft 33 is separated from the surface to be cleaned.

[0184] Exemplarily, the output shaft 33 includes a main shaft and a telescopic rod, the telescopic rod is arranged coaxially with the main shaft, one end of the telescopic rod is connected to the main shaft to rotate with the main shaft, and the other end of the telescopic end is connected to the cleaning member. The main shaft rotates under the action of the input shaft and the transmission body, thereby driving the telescopic rod and the cleaning member to rotate, and the cleaning member is driven to rise and fall by the extension and retraction of the telescopic rod.

[0185] For example, the first driving device 2, the transmission device 3 and the cleaning member 4 can be driven by the body assembly 1 to move up and down as a whole, so as to drive the cleaning member 4 to move in the up and down direction relative to the body.

[0186] It is understandable that the second limiting portion 13 may not be provided, and the cleaning member 4 can be maintained approximately near the second position by balancing the reaction torque applied by the cleaning member 4 and the elastic force of the reset member 5 .

[0187] Exemplarily, the reset member 5 is connected to the body assembly 1 and the transmission body 31 respectively, and the transmission body 31 is pulled to move by the pulling force of the reset member 5, so that the cleaning member 4 is released from the second position and reset.

[0188] For example, referring to Figures 3 to 5 , one end of the reset member 5 is connected to the body assembly 1, and the other end of the reset member 5 is connected to the transmission body 31. The location where the reset member 5 is connected to the transmission body 31 is located on the side of the input shaft 32 facing away from the output shaft 33. When the cleaning member 4 is in the first position, the center line connecting the input shaft 32 and the output shaft 33 and the direction of the elastic force of the reset member 5 are arranged in a cross direction.

[0189] In one embodiment, referring to FIG5 , the body assembly 1 has a first stopper 14. When the cleaning member 4 is in the first position, the first stopper 14 can abut against the transmission device 3 to prevent the transmission device 3 from moving under the action of the reset member 5. With this structure, when the first stopper 14 abuts against the transmission device 3, the first stopper 14 prevents the transmission device 3 from moving under the action of the reset member 5. The transmission device 3 is then reset to its limit position abutting against the first stopper 14 under the action of the reset member 5.

[0190] Illustratively, when the cleaning member 4 is located at the first position, the first limiting portion 14 abuts against the transmission device 3 to limit the position.

[0191] Exemplarily, the body assembly 1 has a second limiting portion 13 and a first limiting portion 14, the transmission device 3 abuts against the second limiting portion 13 to limit the cleaning member 4 to the second position, and the transmission device 3 abuts against the first limiting portion 14 to limit the cleaning member 4 to the first position.

[0192] Exemplarily, the first limiting portion 14 abuts against the transmission body 31 for limiting position.

[0193] Exemplarily, the first limiting portion 14 abuts against the output shaft 33 for limiting position.

[0194] In one embodiment, referring to Figures 3-5 , the body assembly 1 has a connecting mounting cavity 15 and an escape groove 16. A first drive unit 2 and a transmission body 31 are located within the mounting cavity 15. An output shaft 33 extends through the escape groove 16 and partially extends outside the mounting cavity 15. The cleaning member 4 is located outside the mounting cavity 15. This structure allows the first drive unit 2 and transmission body 31 to be located within the mounting cavity 15 of the body assembly 1, minimizing the risk of exposure. The body assembly 1 effectively protects the first drive unit 2 and transmission body 31 within the mounting cavity 15, minimizing the risk of damage from external impacts and other factors. The output shaft 33 partially extends outside the mounting cavity 15, facilitating rotation of the cleaning member 4 outside the mounting cavity 15, thereby cleaning the surface to be cleaned.

[0195] For example, referring to FIG. 3 to FIG. 5 , the avoidance groove 16 is waist-shaped.

[0196] For example, referring to Figures 3 to 5, the second limiting portion 13 is located at one end of the avoidance groove 16, the first limiting portion 14 is located at the other end of the avoidance groove 16, and the groove wall of the avoidance groove 16 spans the second limiting portion 13 and the first limiting portion 14.

[0197] It is understandable that the fuselage assembly 1 may not be provided with the installation cavity 15 and the avoidance groove 16. For example, the first drive device 2 and the transmission body 31 may be arranged below the fuselage assembly 1 as appropriate, and the first drive device 2 and the transmission body 31 are downwardly located outside the fuselage assembly 1.

[0198] For example, please refer to Figures 3 to 6. The fuselage assembly 1 includes a fuselage body 18 and a drive shell 19. The installation cavity 15 and the avoidance groove 16 are formed in the fuselage body 18. The drive shell 19 is located in the installation cavity 15. The drive shell 19 is connected to the fuselage body 18. The transmission body 31 is located in the drive shell 19. The input shaft 32 of the transmission device 3 is rotatably connected to the drive shell 19. The input shaft 32 rotates relative to the drive shell 19, and accordingly, the input shaft 32 rotates relative to the fuselage body 18.

[0199] Exemplarily, the fuselage assembly 1 also includes a lifting cylinder installed on the fuselage body 18, which drives the corresponding drive shell 19 to rise and fall. The transmission body 31 in the drive shell 19 follows the rise and fall of the drive shell 19, driving the corresponding output shaft 33 and the cleaning part 4 on the output shaft 33 to rise and fall together.

[0200] In one embodiment, referring to FIG. 3 to FIG. 5 , FIG. 7 and FIG. 8 , a locking platform 311 is formed on the transmission body 31 .

[0201] In one embodiment, referring to Figures 3 to 5, 7, and 8, the cleaning device further comprises a locking mechanism 6 disposed on the body assembly 1 and configured to lock or unlock the cleaning member 4 in the first position. When the locking mechanism 6 is unlocked, the force generated by the rotation of the cleaning member 4 drives the cleaning member 4 from the first position to the second position.

[0202] In the embodiment of the present application, when the cleaning device is in a non-edge-walking cleaning mode, the cleaning member 4 is locked in the first position by the locking mechanism 6, which is conducive to better cleaning the surface to be cleaned on the path of the cleaning device.

[0203] It should be noted that the locking mechanism 6 is used to lock or unlock the cleaning member 4 located in the first position. The locking mechanism 6 can directly lock or unlock the cleaning member 4, or the locking mechanism 6 can also lock or unlock the transmission device 3 corresponding to the cleaning member 4 located in the first position.

[0204] Exemplarily, the force generated by the rotation of the cleaning member 4 drives the cleaning member 4 to rotate around the input shaft 32 to the first position.

[0205] For example, the cleaning element 4 is locked in the first position by the locking mechanism 6 .

[0206] In one embodiment, referring to Figures 3 to 5, 7, and 8, the locking mechanism 6 can be locked with the locking platform 311 to prevent the cleaning member 4 from moving to the second position. The locking mechanism 6 can also unlock the locking platform 311 to allow the cleaning member 4 to move to the second position. With this structure, the locking mechanism 6 and the locking platform 311 are locked together, making it almost impossible for the output shaft 33 and the transmission body 31 to rotate relative to the input shaft 32. When the cleaning member 4 is normally cleaning the surface to be cleaned, the locking mechanism 6 and the locking platform 311 can prevent the cleaning member 4 from moving to the second position under the action of the counter torque applied by the surface to be cleaned, thereby reducing the possibility of the cleaning member 4 malfunctioning and moving to the second position under the action of the counter torque applied by the surface to be cleaned. When the cleaning member 4 needs to be moved to the second position to clean the corners close to the target edge 9 when the main body 18 is close to the target edge 9, the locking platform 311 can be unlocked by the locking mechanism 6, and the rotation of the output shaft 33 and the transmission body 31 relative to the input shaft 32 is no longer restricted. The cleaning member 4 arranged on the output shaft 33 can rotate around the input shaft 32, thereby moving to the second position.

[0207] It should be explained that, here, the cleaning member 4 cleans the surface to be cleaned normally, which means that the cleaning member 4 cleans the surface to be cleaned in a relatively open place when it is reset after leaving the second position, and the main body 18 is not close to the target edge 9 .

[0208] In one embodiment, referring to Figures 7 and 8 , a locking platform 311 is formed on the transmission device 3, a support portion 17 is formed on the body assembly 1, and the locking mechanism 6 includes a locking pin 61 and a locking elastic member 62. The locking pin 61 is movably disposed on the body assembly 1. The locking elastic member 62 is positioned between the locking pin 61 and the support portion 17, and contacts the locking pin 61 and the support portion 17, respectively. The locking pin 61 can be extended to a locked position under the elastic force of the locking elastic member 62. The locking platform 311 can abut against the locking pin 61 in the locked position to lock the cleaning member 4. With this structural form, the locking elastic member 62 is supported by the support portion 17, and the locking elastic member 62 applies an elastic force to the locking pin 61, so that the locking pin 61 can be extended to the locked position. At the locked position, the locking pin 61 abuts and limits the locking platform 311. The locking platform 311 is blocked by the locking pin 61 and cannot move to the second position, thereby locking the cleaning member 4. The extended locking pin 61 and the locking platform 311 abut and limit the cleaning member 4 to a state of being released from the second position and reset, so that the cleaning member 4 can clean the surface to be cleaned normally. When the locking pin 61 overcomes the elastic force of the locking elastic member 62 and retracts, the locking pin 61 releases the locking platform 311, and the cleaning member 4 moves to the second position, driving the output shaft 33 and the transmission body 31 to rotate about the input shaft 32. The cleaning member 4 can clean the surface to be cleaned near the target edge 9 when the fuselage assembly 1 is close to the target edge 9.

[0209] For example, referring to FIG5 , when the cleaning member 4 is in the first position, the transmission body 31 partially abuts between the locking pin 61 and the first limiting portion 14 , and the first limiting portion 14 and the locking pin 61 constrain the transmission body 31 so that the cleaning member 4 remains in the first position.

[0210] Exemplarily, the locking elastic member 62 may be a spring.

[0211] Exemplarily, the locking platform is formed on the transmission body 31 .

[0212] It is understandable that the body assembly 1 may not be provided with the first limiting portion 14. For example, when the cleaning member 4 contacts the surface to be cleaned, the reaction torque exerted by the surface to be cleaned on the cleaning member 4 and the limiting effect of the locking pin 61 on the locking pot keep the cleaning member 4 in the reset state out of the second position, so that the cleaning member 4 can clean the surface to be cleaned normally.

[0213] In one embodiment, referring to Figures 7 and 8, the locking pin 61 has an actuating portion 611, and the cleaning device further includes a second driving device and a cam 8. The second driving device is mounted on the body assembly 1. The cam 8 is mounted on the second driving device, and the cam 8 and the locking elastic member 62 are respectively located on opposite sides of the actuating portion 611. The second driving device drives the cam 8 to rotate and drive the actuating portion 611 to move, so that the locking pin 61 overcomes the elastic force of the locking elastic member 62 and retracts from the locked position to a position that releases the locking platform 311. In such a structural form, the cam 8 is driven to rotate by the second driving device. When the portion of the cam 8 with a larger radius gradually abuts against the actuating portion 611, the rotating cam 8 pushes the actuating portion 611 of the locking pin 61 to overcome the elastic force of the locking elastic member 62 and move, driving the entire locking pin 61 to release the locking platform 311. The second drive device drives the cam 8 to rotate. When the smaller radius portion of the cam 8 gradually abuts the actuator 611, the actuator 611 extends under the elastic force of the locking elastic member 62, causing the entire lock pin 61 to extend to a locked position abutting the lock base 311. The second drive device drives the cam 8 to rotate, which automatically locks or unlocks the lock base 311.

[0214] Exemplarily, the second driving device may be a motor.

[0215] It is understandable that the embodiment of the present application is not limited to the second driving device driving the cam 8 to rotate so that the lock pin 61 locks or unlocks the lock platform 311. For example, the operator can manually pull the lock pin 61 to switch.

[0216] It is understood that the specific structure of the locking mechanism 6 in the embodiment of the present application is not limited. For example, the transmission body 31 can be limited by a baffle or a block to keep the cleaning member 4 in the reset state of being out of the second position.

[0217] In one embodiment, referring to the figure, the input shaft 32 is rotatably connected to the body assembly 1 at one end thereof, facing away from the cleaning member 4, along the axial direction of the input shaft 32. With this structural configuration, when the cleaning member 4 contacts the surface to be cleaned to clean it, because the end of the input shaft 32 facing away from the cleaning member 4 is rotatably connected to the body assembly 1, the force exerted by the surface to be cleaned on the cleaning member 4 along the axial direction of the input shaft 32 can be largely balanced by the force exerted by the body assembly 1 on the end of the input shaft 32 facing away from the cleaning member 4. This prevents the cleaning member 4 from lifting relative to the body assembly 1, creates greater friction between the cleaning member 4 and the surface to be cleaned, and facilitates better cleaning of the surface by the cleaning member 4.

[0218] It is understood that the position of the rotational connection of the input shaft 32 is not limited. For example, both ends of the input shaft 32 pass through the transmission body 31. One end of the input shaft 32, which faces the cleaning element 4 along the axial direction of the input shaft 32, is rotationally connected to the body assembly 1. The other end of the input shaft 32, which faces away from the cleaning element 4 along the axial direction of the input shaft 32, is spaced apart from the body assembly 1. For example, both ends of the input shaft 32 pass through the transmission body 31, and both ends of the input shaft 32 can be rotationally connected to the body assembly 1.

[0219] Second embodiment:

[0220] It should be understood that the orientation descriptions "above", "below", "outside" and "inside" are all orientations in normal use status, and the directions "left" and "right" represent the left and right directions shown in the specific corresponding schematic diagrams, which may or may not be the left and right directions in normal use status.

[0221] As shown in Figures 9 and 10, Figure 9 illustrates the front side of a cleaning device 901 during normal use, and Figure 10 illustrates the back side of the cleaning device 901 during normal use. The present embodiment of the utility model provides a cleaning device 901 that can be used to automatically clean dust and hair from a floor. If a rag is provided on the cleaning device 901, the cleaning device 901 can mop the floor after cleaning it.

[0222] For example, the dust collection principle of cleaning device 901 when cleaning the floor can be understood as follows: cleaning device 901 has three cleaning functions: dust collection, dust collection, and dust filtration. When the machine is operating normally, the DC motor in the vacuum cleaner drives the fan impeller to rotate at high speed, causing air to be discharged at high speed. A momentary vacuum is generated inside the dust collector, forming a negative pressure difference with the external atmospheric pressure. Under the action of the pressure difference, the air in the dust suction port at the front end of the fan continuously replenishes the air in the fan. The vacuum cleaner inhales the dust-laden air, filters it through the dust filter, and discharges clean air. The filtered garbage is collected in the dust box.

[0223] For example, the cleaning device is a cleaning robot.

[0224] As shown in FIG11 and FIG12 , the cleaning device 901 includes a device body and a cleaning device. The cleaning device is installed on the device body. The cleaning device includes a cleaning member. The device body or the cleaning device drives the cleaning member to move to clean the surface to be cleaned.

[0225] The main body of the device includes a chassis assembly, and the cleaning device is a mopping pan assembly. Multiple mopping pan assemblies 903 are provided, and these mopping pan assemblies 903 are evenly arranged behind the chassis assembly 902, thereby increasing the cleaning range of the mopping pan assemblies 903. The mopping pan assemblies 903 are rotatably connected to the chassis assembly 902, and at least partially protrude from the chassis assembly 902 to clean the floor. During the cleaning process of the cleaning device 901, the mopping pan assemblies 903 rotate relative to the chassis assembly 902, so that the portion of the mopping pan assemblies 903 protruding from the chassis assembly 902 rubs against the floor, thereby cleaning the floor. The mopping disc assembly 903 is provided with a receiving space 904 recessed toward the chassis assembly 902. During the actual use of the cleaning device 901, the cleaning device 901 moves on the ground, and the mopping disc assembly 903 at least partially protrudes downward from the chassis assembly 902 to contact and clean the floor; the chassis assembly 902 is located above the mopping disc assembly 903. Up and down refer to the direction of the cleaning device 901 relative to the ground during actual use. Downward means approaching the ground, and upward means moving away from the ground.

[0226] As shown in Figures 11 and 12, the mopping disc assembly 903 is provided with an upwardly recessed receiving space 904, thereby forming a recessed receiving space 904 between the mopping disc assembly 903 and the floor. During the operation of the cleaning device 901, the mopping disc assembly 903 attracts metal parts. The present embodiment does not limit the method by which the mopping disc assembly 903 attracts metal parts; for example, electrostatic attraction or magnetic attraction may be used. The receiving space 904 is used to accommodate the attracted metal parts. The bottom of the mopping disc assembly 903 forming the receiving space 904 has a first surface 905. Metal parts on the floor are attracted to the first surface 905 and accumulate in the receiving space 904. The first surface 905 is recessed toward the chassis assembly 902, i.e., the first surface 905 is recessed upward. This increases the distance between the first surface 905 and the floor when the cleaning device is in use, further increasing the volume of the receiving space 904, and thus increasing the number of metal parts that can be accommodated in the receiving space 904.

[0227] The bottom of the embodiment of the utility model has a first surface, which is recessed toward the chassis assembly to form a accommodating space. During the movement of the cleaning device, metal parts on the floor are adsorbed to the first surface and accumulated in the accommodating space. Since the first surface is recessed toward the chassis assembly, the distance between the first surface and the floor of the cleaning device is increased when in use, and the accommodating volume of the accommodating space is further increased, so that the metal parts adsorbed to the first surface are farther away from the floor, and the accommodating space can also adsorb more metal parts, so that the metal parts accumulated at the bottom of the cleaning device are not easy to scratch the floor, which is beneficial to improving the user experience.

[0228] In some embodiments, as shown in Figures 11 and 12 , the mopping pan assembly 903 includes a mopping pan body 906 and a mopping pan cover 907. The mopping pan body 906 is rotatably connected to the chassis assembly 902. A rag 909 is mounted on a side of the mopping pan body 906 away from the chassis assembly 902. The rag 909 is removable and replaceable and is used to contact and clean the floor. The mopping pan cover 907 is connected to the mopping pan body 906 and is located in the middle of the mopping pan body 906. The mopping pan cover 907 is removable relative to the mopping pan body 906. The rag 909 is arranged around the middle of the mopping pan cover 907. As shown in Figures 13 and 14 , the recess 908 shown in Figure 13 is recessed. The side of the mopping pan cover 907 that is closest to the accommodating space 904 is a first surface 905. This first surface 905 of the mopping pan cover 907 is at a certain distance from the floor, allowing the rag 909 to contact the floor. Thus, the rag 909 and the mopping pan cover 907 together form the accommodating space 904. The first surface 905 is recessed away from the floor to form a recess 908, thereby increasing the volume of the accommodating space 904. The depth of the accommodating space 904 is affected by the thickness of the rag 909. If rags 909 of varying thickness are installed in the mopping pan body 906, the size of the accommodating space 904 will vary. The thicker the rag 909, the deeper the accommodating space 904.

[0229] The mop pan assembly of the embodiment of the utility model includes a mop pan body and a mop pan cover. The side of the mop pan cover close to the accommodating space is a first surface, and the first surface is recessed to form a recess. When the user needs to replace the mop pan cover with a recess of a different size, it is only necessary to remove the mop pan cover and replace it. When cleaning the metal parts in the accommodating space, the mop pan cover can also be directly removed for cleaning, thereby facilitating the use of the user.

[0230] In some embodiments, as shown in Figures 13 and 14, the outer diameter of recess 908 ranges from 10 mm to 20 mm. The larger the outer diameter of recess 908, the more metal parts it can accommodate; and / or the depth of recess 908 ranges from 1 mm to 3 mm. The greater the depth of recess 908, the more metal parts it can accommodate. The embodiments of the present invention limit the outer diameter range and / or the depth range of the recess. Within this range, the outer diameter and / or the depth of recess 908 are appropriate to accommodate a certain volume of metal parts, thereby reducing the risk of the floor being scratched by accumulated metal parts to a certain extent. At the same time, it can save material for the mop cover and reduce the space it occupies, ensuring the compactness of the overall structure of the cleaning device.

[0231] In some embodiments, as shown in Figures 13 and 14, the mop pan cover 907 is a magnetic component that is used to attract metal parts. For example, the mop pan cover 907 can be made of materials such as magnets. In the embodiment of the utility model, the mop pan cover itself is a magnetic component that is used to attract metal parts. Therefore, the magnetic attraction force generated by the mop pan cover itself is relatively large, and the metal parts are easily attracted to the first surface of the mop pan cover and are not easily scattered elsewhere, thereby reducing the possibility of metal parts scratching the floor. In addition, the mop pan cover and the rag form a storage space and also serve as a magnetic component, realizing multiple functions of one component, thereby reducing the need for the provision of other components. In other words, there is no need to provide other magnetic components for adsorption, thereby saving production costs and ensuring the compactness of the overall structure of the cleaning device.

[0232] In some embodiments, as shown in Figures 11 and 12, the mopping pan assembly 903 further includes a magnetic assembly 910. A space is provided between the mopping pan cover 907 and the mopping pan body 906 for mounting the magnetic assembly 910. The magnetic assembly 910 is used to attract metal components. The magnetic assembly 910 is fixed to the mopping pan body 906, so that the magnetic assembly 910 does not easily wobble in the area between the mopping pan cover 907 and the mopping pan body 906, thereby ensuring its stability in attracting the metal components. The mopping pan assembly of this embodiment of the utility model further includes a magnetic assembly. By separately providing the magnetic assembly for attracting metal components, the mopping pan cover does not need to be used as a magnetic attraction component. Therefore, it can be made of a relatively easy-to-process and cheaper material, such as plastic. Therefore, by separately providing the magnetic assembly, the mopping pan cover can be easily processed and manufactured during actual production.

[0233] In some embodiments, as shown in FIG12 , the magnetic assembly 910 includes a fixing bracket 911 and a magnetic member 912. The fixing bracket 911 is fixed to the mopping pan body 906, thereby preventing the fixing bracket 911 from easily swinging in the area between the mopping pan cover 907 and the mopping pan body 906. The magnetic member 912 can be stably disposed within the fixing bracket 911 to attract metal components. For example, the magnetic member 912 can be made of a material such as a magnet. The magnetic member 912 is disposed adjacent to the first surface 905 of the mopping pan cover 907, so that the magnetic field generated by the magnetic member 912 easily covers the accommodation space 904 below the mopping pan cover 907 and stably attracts the metal component to the first surface 905.

[0234] The magnetic assembly of the embodiment of the utility model includes a fixed bracket and a magnetic part. The fixed bracket is fixed to the mop plate body to facilitate the stable setting of the magnetic part. The adsorption function of the magnetic part is strong. By setting the magnetic part, the cleaning device can better adsorb metal parts. In addition, the material of the magnetic part is very common in life and is cheap, which can save mass production costs.

[0235] In some embodiments, as shown in FIG15 , the chassis assembly 902 includes a third drive device 913 for driving the mopping disc assembly 903 to rotate. The third drive device 913 is connected to the magnetic assembly 910 via a drive shaft 914. The magnetic assembly 910 is fixedly connected to the mopping disc body 906. Thus, the third drive device 913 drives the mopping disc body 906 to rotate via the drive shaft 914 to clean the floor. For example, the third drive device 913 can be driven by a motor or a mechanical drive. The chassis assembly of the present embodiment includes a third drive device for driving the mopping disc assembly to rotate. The third drive device is connected to the magnetic assembly via a drive shaft, thereby driving the mopping disc body to rotate to clean the floor. The third drive device provides driving force for the rotation of the mopping disc body, allowing the cleaning device to operate normally, ensuring the stability of the rotation of the mopping disc body and the efficiency of the cleaning device.

[0236] In some embodiments, as shown in Figures 11 and 12, the drive shaft 914 is ferromagnetic and can exhibit magnetism by being in contact with or positioned close to the magnetic member 912. In other words, being positioned close to the magnetic member 912 means that the distance between the drive shaft 914 and the magnetic member 912 ensures that the drive shaft 914 exhibits magnetism in the divergent magnetic field of the magnetic member 912. For example, the distance between the drive shaft 914 and the magnetic member 912 is no more than 20 mm. For example, the drive shaft 914 is a metal shaft.

[0237] It should be noted that after the drive shaft 914 contacts the magnetic member 912 , the drive shaft 914 becomes magnetic. When the drive shaft 914 separates from the magnetic member 912 , the drive shaft 914 becomes demagnetized.

[0238] The sensing element is disposed on the chassis assembly 902 and includes a sensor and a magnetic conductor. The sensor and the magnetic conductor are disposed adjacent to each other to detect the magnetic field of the drive shaft 914. The type of the sensing element is not limited and may be a Hall sensor, a magnetoresistive sensor, or a fluxgate sensor.

[0239] It can be understood that if the sensor can detect the magnetic signal of the drive shaft 914, it is confirmed that the mopping disc assembly 903 is located at the bottom end of the drive shaft 914; if the sensor does not detect the magnetic signal of the drive shaft 914, it is confirmed that the mopping disc assembly 903 is not installed at the bottom end of the drive shaft 914. In other words, by detecting the magnetism of the drive shaft 914 through the sensor, it is possible to detect whether the mopping disc assembly 903 is installed in place, or detect whether the mopping disc assembly 903 falls off during the cleaning process.

[0240] Proximity placement means placing the magnet close to the sensor. For example, the distance between the magnet and the sensor is no more than 20 mm. Preferably, the sensor's induction head and the magnet are perpendicular to each other. The specific arrangement of proximity placement is not limited.

[0241] It is understandable that due to the limitation of sensor sensitivity, the effective detection distance of the sensor is generally 0 to 20 mm. Theoretically, improving the sensitivity of the sensor and increasing the magnetic field strength of the corresponding magnetic component 912 can expand the detection distance. However, in actual application, the structural space is generally limited, and the size of the magnetic component 912 cannot be increased indefinitely. Once the sensor selection and structural design are completed, it is difficult to adjust the above two parameters.

[0242] In the embodiment of the present application, a magnetic conductor can be arranged around the sensor to focus the magnetic field.

[0243] The material of the magnetic conductor is not limited and can be a common metal material with good magnetic conductivity. For example, the material of the magnetic conductor can be pure iron, low carbon steel, ferrosilicon alloy or iron-nickel alloy.

[0244] It should be noted that the reason why the magnet has high magnetic conductivity is that there are spontaneous magnetization units inside the magnet, called magnetic domains. Under normal circumstances, the magnetic domains are arranged in a disorderly manner and therefore do not show magnetism to the outside. However, under the action of an external magnetic field, the magnetic domains are arranged regularly along the direction of the external magnetic field, thereby forming an additional magnetic field superimposed on the external magnetic field. It is understandable that there is a gap between the magnet and the drive shaft 914 to be measured of the sensor element. The magnet produces a certain magnetization, which will form a gap field between the drive shaft 914 to be measured. In this way, the gap field will concentrate the magnetic lines of force on the side of the drive shaft 914 to be measured close to the sensor element, which can increase the suction force and magnetic density, thereby increasing the magnetic field. In other words, the magnet can change the magnetic lines of force of the gap field, thereby changing the magnetic flux, and then changing the magnetic field strength.

[0245] The cleaning device 901 provided in the embodiment of the present application can detect the mopping disc assembly 903 through the sensing element and the magnetic member 912. Specifically, the presence of the mopping disc assembly 903 is detected by the sensing element sensing the magnetism of the drive shaft 914, thereby achieving high detection accuracy. Furthermore, by providing a magnetic conductor, the previously dispersed magnetic field can be gathered near the sensor, increasing the magnetic field strength near the sensor and making it easier for the sensor to detect the magnetic signal from the magnetized drive shaft 914. This in turn increases the sensor's detection distance, improves the sensor's sensitivity, and further enhances detection accuracy. Furthermore, by using a pre-installed sensor, the sensor's detection performance can be improved by simply adding a magnetic conductor during installation, which is cost-effective and facilitates the sensor's expanded use.

[0246] In some embodiments, as shown in Figures 11 and 12, the mopping disc body 906 is disposed around the outside of the drive shaft 914, and the magnetic assembly 910 is connected between the mopping disc body 906 and the drive shaft 914. It can be understood that the mopping disc body 906, the magnetic assembly 910, and the drive shaft 914 are disposed and connected in sequence. In the embodiment of the present invention, the mopping disc body is disposed around the outside of the drive shaft, and the magnetic assembly is connected between the mopping disc body and the drive shaft. Thus, the arrangement of the magnetic assembly more fully utilizes the gap between the mopping disc body and the drive shaft, making the overall structure more compact and facilitating the miniaturization of the cleaning device.

[0247] In some embodiments, as shown in FIG10 , the cleaning device 901 further includes a side brush 915 and / or a roller brush 916. The side brush 915 is disposed at the front corner of the chassis assembly 902 to clean debris at the corners of the floor; the roller brush 916 is disposed in the middle of the chassis assembly 902 to clean debris in the middle of the floor. When the cleaning device 901 is cleaning the floor, a rotating roller brush 916 is provided in the middle area of ​​the bottom of the cleaning device 901 to roll up larger debris and dirt on the floor; two relatively rotating side brushes 915 are installed on the left and right sides of the bottom front of the cleaning device 901 to increase the effective area of ​​the floor cleaned each time, and to sweep dust and garbage from corners and under furniture into the cleaning device 901.

[0248] The cleaning device of the embodiment of the present invention also includes a side brush and a roller brush. The roller brush can roll up larger debris and dirt on the ground; the side brush can be used to increase the effective area of ​​the ground swept each time, and sweep dust and garbage in corners and under furniture into the cleaning device; after the side brush and the roller brush sweep the floor, the rag can easily clean finer dirt and dust on the ground, making the ground cleaner and tidier; through the side brush, the roller brush and the rag, the ground can be cleaned more comprehensively.

[0249] In some embodiments, as shown in Figures 9 and 10, a power terminal 917 is provided on the rear side of the cleaning device 901 for electrically connecting to the cleaning base station to charge the cleaning device 901. The power terminal is provided on the rear side of the cleaning device of the embodiment of the present invention, which can be used to electrically connect to the charging terminal of the cleaning base station, thereby ensuring that the cleaning device can be charged after returning to the cleaning base station, and ensuring that the battery of the cleaning device is sufficiently charged and can operate normally after leaving the cleaning base station.

[0250] The cleaning device 901 mainly moves on the ground to perform vacuum cleaning and mopping cleaning. Vacuum cleaning mainly uses a fan to suck the garbage on the ground into the dust box inside the cleaning device 901 for collection. When the cleaning device 901 works for a certain period of time, the garbage in the dust box needs to be dumped and disposed of; mopping cleaning mainly uses cleaning parts to mop the ground. When the cleaning device 901 works for a certain period of time, the cleaning parts need to be cleaned.

[0251] Exemplarily, the cleaning base station is used to perform at least one of charging, dust removal, and mop cleaning on the cleaning device 901 docked in its accommodation space.

[0252] Regarding the communication method between the cleaning device 901 and the cleaning base station, for example, the cleaning device 901 includes a first communication module, and the cleaning base station includes a second communication module. The cleaning device 901 and the cleaning base station can communicate with each other through the first communication module and the second communication module. For example, when the cleaning device 901 needs to remove dust or charge, it can communicate wirelessly through the first communication module and the second communication module, thereby returning to the cleaning base station.

[0253] Exemplarily, the first communication module and the second communication module may include but are not limited to one or more wireless data communication modules such as a Bluetooth module, a Wireless Fidelity (WIFI) module, a fourth generation or fifth generation (4G / 5G) communication module or an infrared module.

[0254] Third embodiment:

[0255] It should be understood that the terms used herein are for the purpose of describing specific example embodiments only and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "one", "an", and "" as used herein may also be meant to include plural forms. The terms "comprise", "include", "contain", and "have" are inclusive and therefore specify the presence of the stated features, steps, operations, elements, and / or parts, but do not exclude the presence or addition of one or more other features, steps, operations, elements, parts, and / or combinations thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring them to be performed in the specific order described or illustrated, unless the order of execution is clearly indicated. It should also be understood that additional or alternative steps may be used.

[0256] Although the terms first, second, third, etc. can be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms can only be used to distinguish an element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second" and other numerical terms do not imply order or sequence when used in the text. Therefore, the first element, component, region, layer or section discussed below can be referred to as the second element, component, region, layer or section without departing from the teaching of the example embodiments.

[0257] For ease of description, spatially relative terms may be used herein to describe the relationship of one element or feature relative to another element or feature as shown in the figures, such as "inside", "outside", "inside", "outside", "below", "beneath", "above", "over", etc. Such spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is flipped, then an element described as "below" or "below" other elements or features would then be oriented as "above" or "above" other elements or features. Thus, the example term "below" can include both above and below orientations. The device can be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein are interpreted accordingly.

[0258] A cleaning appliance is an intelligent household cleaning device that automatically sweeps away dust, debris, and crumbs from floors. It uses a built-in sensor system to sense its surroundings and then uses a motorized brush and vacuum to clean the floor. It can clean an entire room using a pre-set route or random motion, avoiding obstacles and edges.

[0259] Modern cleaning equipment is usually equipped with multiple functions. For example, a mopping function is achieved by adding a cleaning component. The mop of the cleaning component can be a rotating type that can rotate, a vibrating type that can vibrate, or a traditional fixed type. However, when the above cleaning components are used to clean the floor near the wall or cabinet, the mopping effect cannot meet the user's satisfaction. The reason is that when the body of the cleaning device moves to contact the wall or cabinet, the mop and other cleaning parts cannot move toward the wall or cabinet, resulting in the cleaning component being able to perform mopping operations only within a certain range and unable to cover all areas near the wall or cabinet.

[0260] In view of this, the present embodiment provides a cleaning device, which aims to improve its structure so that cleaning parts such as a mop can be extended or retracted into the body to perform all-round cleaning of the wall or cabinet edge.

[0261] The cleaning device may be a self-moving cleaning device.

[0262] The structure of the cleaning device provided in this embodiment is described below with reference to Figures 16-25.

[0263] Figure 16 schematically illustrates a schematic structural diagram of a cleaning device according to an embodiment of the present invention, Figure 17 schematically illustrates a schematic structural diagram of a cleaning device according to an embodiment of the present invention when the cleaning member is retracted, and Figure 18 schematically illustrates a schematic structural diagram of a cleaning device according to an embodiment of the present invention when the cleaning member is extended. It should be noted that Figure 16 illustrates a schematic structural diagram of the bottom structure of the cleaning device, while Figures 17 and 18 only illustrate partial structural diagrams of the lower shell of the cleaning device body.

[0264] As shown in Figures 16, 17 and 18, the cleaning device 901 provided in this embodiment includes an equipment body and a cleaning device. The cleaning device is installed on the equipment body. The cleaning device includes a cleaning piece. The equipment body or the cleaning device drives the cleaning piece to move to clean the surface to be cleaned.

[0265] The cleaning device is a cleaning component 945. The main body of the equipment includes a body 919 and a telescopic drive component 929. The telescopic drive component 929 is installed on the body 919. The telescopic drive component 929 is used to drive the cleaning member 4 to move between a first position and a second position. The first position corresponds to the retracted state of the telescopic drive component 929, and the second position corresponds to the extended state of the telescopic drive component. The telescopic drive component 929 is used to drive the cleaning component 945 to move, so as to drive at least part of the cleaning member 4 of the cleaning component 945 to extend or retract from one side of the body 919. Specifically, in the extended state in Figure 18, at least part of the body of the cleaning member protrudes from the outside of the circumferential side wall of the body. In the retracted state in Figure 17, the cleaning member is placed on the inner side of the circumferential side wall of the body.

[0266] Among them, the body 919 of this embodiment serves as the installation base of various functional components, which includes an upper shell (not shown in the figure) and a lower shell 920 connected to each other, running wheels 927 that drive the body 919 to move, and a dust suction component 928 for absorbing dust.

[0267] The telescopic drive component 929 of this embodiment is installed on the body 919, for example, between the upper shell and the lower shell 920. The "telescopic" in the telescopic drive component 929 can be understood as driving the cleaning component 4 of the cleaning component 945 to extend or retract, and cannot be simply understood as the driving form of the telescopic drive component 929 being a telescopic form. As long as the driving structure has the function of driving the cleaning component 4 to extend and retract, it can be used as the telescopic drive component 929 of this embodiment. The possible implementation methods of the telescopic drive component 929 are given below.

[0268] The cleaning assembly 945 of this embodiment can be a conventional mopping assembly or a motorized brush assembly. When the cleaning assembly 945 of this embodiment is a mopping assembly, the cleaning member 4 can be a mop cloth, and the structure in which the mopping assembly drives the mop cloth to mop the floor can be a rotating, vibrating, or fixed structure. In addition, when the cleaning assembly 945 of this embodiment is a mopping assembly, the cleaning device 901 can be equipped with a motorized brush assembly on the side facing away from the mopping assembly.

[0269] The cleaning member 4 of this embodiment is at least partially extended or retracted from one side of the body 919 under the drive of the telescopic drive assembly. The term "at least partially" can be understood as part of one side, most of one side, or the entire cleaning member 4. The term "extending or retracting from one side of the body 919" should be understood in a broad sense. For example, it can be understood that the cleaning member 4 extends or retracts within the range of the orthographic projection of the bottom of the body 919 on the ground. Therefore, the position of the cleaning member 4 should be within the range of the orthographic projection or the contour of the body 919. It should not be understood that the cleaning assembly 945 must be located inside the body 919. For example, a receiving groove 921 can be provided on the outer wall surface of the bottom wall of the lower shell 920 of the body 919 of this embodiment. The receiving groove 921 is open at the bottom and has an inlet and outlet opening on at least one side in the horizontal direction. The cleaning member 4 is located in the receiving groove 921 and extends or retracts from the inlet and outlet opening. The cleaning member 4 located in the receiving groove 921 is not completely located in the body 919, but is only located in the receiving groove 921 at the bottom of the body 919, and may be partially located in the receiving groove 921 in the vertical direction, but may not necessarily be completely accommodated in the receiving groove 921.

[0270] In some examples, optionally, the number of cleaning components 945 of this embodiment can be two. For example, two cleaning components 945 for mopping the floor can form a complete work surface, but only one cleaning component 945 can be connected to the telescopic drive component 929 of this embodiment. The reason is that when cleaning a corner of a wall on one side, only one cleaning component 4 needs to be extended. When the cleaning device 901 provided by the embodiment of the present invention is used to wipe the ground near the bottom of the wall, the telescopic drive component 929 can drive the cleaning component 4 near the wall in one cleaning component 945 to extend from one side of the body 919, so that the cleaning component 945 can cover the ground near the bottom of the wall and can clean the right angle between the wall and the ground. Compared with the existing cleaning device 901, the cleaning effect and cleaning efficiency near the bottom of the wall can be improved. When there is no need to clean near the wall, the extended cleaning component 945 is retracted so that the two cleaning components 945 can form a complete work surface during the walking process.

[0271] Exemplarily, the telescopic drive assembly 929 has an extended state and a retracted state that can be switched to each other.

[0272] Illustratively, the cleaning assembly 945 is connected to the telescopic drive assembly 929 .

[0273] The telescopic drive assembly 929 of this embodiment can have various structural forms. In some examples, the telescopic drive assembly 929 of this embodiment optionally includes a first drive component 930 and a transmission mechanism 932. The first drive component 930 is mounted on the body 919, and the transmission mechanism 932 is connected to the first drive component 930 and the cleaning assembly 945, respectively, and is used to drive the cleaning member 4 to extend or retract, that is, the transmission mechanism 932 is used to drive the cleaning member 4 to move between the first position and the second position.

[0274] Illustratively, the transmission mechanism 932 has the aforementioned extended state and retracted state.

[0275] The first driving component 930 of this embodiment can generate a driving force by being energized or other means, and transmit the driving force to the transmission mechanism 932 of this embodiment, which then converts the transmission and driving force, ultimately driving the cleaning member 4 of this embodiment to extend or retract. Of course, the telescopic driving assembly 929 of this embodiment can also be directly a telescopic rod assembly or a swing rod assembly, etc. The telescopic rod assembly can be pneumatic, electric or hydraulic, and can drive the cleaning assembly 945 to move linearly by its own extension and retraction to achieve the extension or retraction of the cleaning member 4. The swing rod assembly can drive the cleaning assembly 945 to swing by its own swing to achieve the extension or retraction of the cleaning member 4.

[0278] The rotating shaft of the first motor 931 is coaxially connected to the first transmission gear 933 and can rotate synchronously. The first transmission gear 933 and the first transmission rack 934 are meshed with each other. The first transmission rack 934 is fixedly connected to the cleaning assembly 945. When the rotating shaft of the first motor 931 rotates, it drives the first transmission gear 933 to rotate, and then drives the first transmission rack 934 and the cleaning assembly 945 to move in a straight line to realize the extension or retraction of the cleaning member 4.

[0279] Of course, the structural form of the first transmission mechanism 932 of this embodiment is not limited to this.

The fixed connection method can be welding or threaded connection, or the two can be formed as one piece during processing.

[0282] In some examples, the transmission frame 935 is optionally slidably connected to the body 919. Designing the transmission frame 935 and the body 919 to be slidably connected allows the transmission frame 935 to slide within the body 919 while moving under the drive of the first transmission gear 933, thereby improving the stability of the transmission frame 935 during movement, thereby improving the stability of the telescopic movement of the cleaning member 4.

[0283] FIG22 schematically shows a partial structural diagram of the housing of the cleaning device according to an embodiment of the present invention.

[0284] As shown in FIG. 22 , in some examples, optionally, the transmission frame 935 is provided with a sliding hole 936 and a sliding member 937, the sliding member 937 having a first end and a second end opposite to each other (not marked in the figure), the first end being connected to the body 919, the second end being passed through the sliding hole 936 and provided with a third limiting portion 938, the third limiting portion 938 being used to limit the movement of the transmission frame 935 away from the first end.

[0285] A sliding hole 936 and a sliding member 937 are provided on the transmission frame 935. The sliding member 937 can be a structure such as a screw. The first end of the sliding member 937 is the tip of the screw, and the second end of the sliding member 937 is the end of the screw with a nut. During assembly, the first end is first passed through the sliding hole 936 and threadedly connected to the body 919, and then the second end is located in the sliding hole 936, and the nut is loosely matched or offset with the transmission frame 935 around the sliding hole 936. The nut can limit the movement of the transmission frame 935 away from the first end.

[0286] In addition, in order to further improve the stability of the transmission frame 935 during movement and enable the transmission frame 935 to move along the third direction, this embodiment further improves the structure of the transmission frame 935 and the body 919.

[0287] FIG22 schematically shows a partial structural diagram of the shell of the cleaning device according to an embodiment of the present invention, and FIG23 is an enlarged view of part a of FIG22 .

[0288] As shown in Figures 21, 22 and 23, in some examples, the transmission frame 935 of this embodiment is provided with a first guide structure 939, and accordingly, a second guide structure 922 is provided on the lower shell 920 of the body 919. The first guide structure 939 and the second guide structure 922 cooperate to guide the movement of the transmission frame 935 along the third direction.

[0289] In some examples, optionally, the first guide structure 939 of this embodiment includes a first guide plate 940 and a second guide plate 942 arranged relative to each other along a fourth direction, the fourth direction being perpendicular to the third direction, and the second guide structure 922 includes a support boss 923, which is located between the first guide plate 940 and the second guide plate 942.

[0290] The first guide plate 940 and the second guide plate 942 are parallel to each other and can be installed vertically on the transmission frame 935. The length directions of the first guide plate 940 and the second guide plate 942 extend along the third direction shown in the figure. The support boss 923 can be a runway shape as shown in the figure, or a rectangle or other similar shape. When the transmission frame 935 moves, the first guide plate 940 and the second guide plate 942 are limited by the support boss 923 to guide the moving direction of the transmission frame 935.

[0291] In some examples, optionally, the second guide structure 922 of this embodiment further includes a support bar 924, the first guide plate 940 is located between the support bar 924 and the support boss 923, the first guide plate 940 is provided with a plurality of protrusions 941 along a third direction, the side of the support bar 924 facing the first guide plate 940 is provided with a plurality of ribs 925 along the aforementioned third direction, a plurality of grooves 926 are formed between the plurality of ribs 925, the number of grooves 926 is greater than the number of protrusions 941, and the plurality of protrusions 941 are located one-to-one in some of the plurality of grooves 926.

[0292] The length direction of the support bar 924 extends along the third direction shown in the figure. The support bar 924 is not only used to support the first guide plate 940 adjacent to it, but also a plurality of grooves 926 are provided on the support bar 924, and a plurality of protrusions 941 are provided on the first guide plate 940. The number of grooves 926 is greater than the number of protrusions 941. The plurality of protrusions 941 convert the surface contact of the first guide plate 940 with the support boss 923 and the support bar 924 into point contact, thereby reducing the friction between the first guide plate 940 and the support boss 923 and the support bar 924. Of course, a protrusion 941 can also be provided on the second guide plate 942 of this embodiment to reduce the friction between the second guide plate 942 and the support boss 923.

[0293] Again referring to Figures 20 and 21 , in some examples, optionally, the cleaning assembly 945 of this embodiment includes a second driving component 950 , which is connected to the cleaning member 4 and is used to drive the cleaning member 4 to perform a cleaning action.

[0294] The second driving component 950 of this embodiment may include a second motor 951. The rotation of the rotating shaft of the second motor 951 drives the cleaning member 4 to perform a cleaning action. For example, when the cleaning member 4 is a mop, the second motor 951 can drive the cleaning member 4 to rotate to mop the floor. Of course, the second driving component 950 of this embodiment may also be a vibration member (this embodiment is not shown in the figure), which drives the cleaning member 4 to mop the floor through vibration.

When the telescopic drive assembly 929 is in the retracted state shown in Figure 17, the mating assembly is in the fourth position. The in-position detection assembly 952 is configured to detect whether the mating assembly is in the third position or the fourth position.

[0296] When the mating assembly is in the third position, the cleaning member 4 moves to the extreme position outside the body 919. When the mating assembly is in the fourth position, the transmission frame 935 drives the cleaning member 4 to move to the inside of the accommodating groove 921, and can abut against or have a gap with the side wall of the accommodating groove 921.

[0297] The in-place detection component 952 can determine whether the cleaning element 4 has moved to the extreme position outside the body 919, ensuring the cleaning effect of the cleaning element 4 on the wall or the floor near the cabinet during cleaning, and can determine whether the cleaning element 4 is located at the extreme position in the accommodating groove 921, so that the two cleaning elements 4 can form a complete cleaning surface when the cleaning device 901 moves back and forth.

[0299] The first in-place detection member 953 and the second in-place detection member 954 of this embodiment can be existing contact sensors. When the first matching structure 943 abuts against the first in-place detection member 953, the first in-place detection member 953 transmits the signal of the detected first matching structure 943 to the controller inside the cleaning device 901 (not shown in the figure). When the second matching structure 944 abuts against the second in-place detection member 954, the second in-place detection member 954 transmits the signal of the detected second matching structure 944 to the controller inside the cleaning device 901, so that the controller determines whether the cleaning member 4 retracts or extends to the preset position.

[0300] Of course, the structural form of the in-place detection component 952 of this embodiment is not limited to the above-mentioned first in-place detection component 953 and second in-place detection component 954. For example, the in-place detection component 952 can also be a distance sensor, which detects the distance from the transmission frame 935 or the transmission rack through infrared or other means. The controller of the cleaning device 901 determines whether the cleaning component 4 is retracted or extended to the preset position based on the detected distance.

[0301] In some examples, when the transmission mechanism 932 of this embodiment includes a first transmission gear 933, a first transmission rack 934, and a transmission frame 935, the aforementioned first mating structure 943 can be directly provided on one end of the first transmission rack 934. The first mating structure 943 can be integrally formed with the first transmission rack 934, so that the first transmission rack 934 can not only transmit power but also perform an in-position detection function, achieving multi-functionality. In addition, the second mating structure 944 can be formed on the second guide plate 942 on the transmission frame 935, thereby improving the functionality of the second guide plate 942.
