[0037] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present 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 the present application and should not be regarded as an improper limitation on the present application.

[0038] In the description of the embodiments of the present application, "upper", "lower", "top", "bottom", orientation or position relationship is based on the attached Figure 1It should be understood that these directional terms are only used to facilitate the description of the present application and simplify 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 limiting the present application. For example, please refer to Figure 1 , the up and down directions are the directions indicated by arrow R1 in the figure.

[0039] In the related art, the cleaning device cleans the ground by rotating the cleaning member in the cleaning working condition. After the cleaning of the cleaned object is completed, in other working conditions, such as the transfer working condition in which the cleaning device moves to the base station after cleaning, there is sewage and other dirt left on the cleaning member, and the cleaning member needs to be separated from the ground as much as possible to prevent the sewage and other dirt on the cleaning member from polluting the ground again. However, the cleaning member of the current cleaning device is difficult to be separated from the ground because it cannot be raised or lowered, and it is difficult to meet both the cleaning working condition and the transfer working condition, making it difficult for the cleaning device to meet multiple different use conditions.

[0040] In view of this, the present application embodiment provides a cleaning device, please refer to Figure 1 and Fig. 9 The cleaning device comprises a body assembly 1, a driver 2, a mounting frame 3 and a cleaning member 4. The driver 2 is mounted on the body assembly 1. The mounting frame 3 is rotatably connected to the body assembly 1, and the central axis of rotation of the mounting frame 3 relative to the body assembly 1 is a first axis 31. The driver 2 is used to drive the mounting frame 3 to rotate. The cleaning member 4 is rotatably connected to the mounting frame 3, and the central axis of rotation of the cleaning member 4 relative to the mounting frame 3 is a second axis 41. The first axis 31 and the second axis 41 are arranged at intervals.

[0041] The first axis 31 and the second axis 41 are arranged at an interval, and the rotation center of the cleaning member 4 deviates from the rotation center of the mounting frame 3 .

[0042] Exemplarily, the first axis 31 and the second axis 41 are both arranged substantially horizontally.

[0043] Exemplarily, the driver 2 is a motor or a rotary cylinder.

[0044] Exemplarily, the motor has a self-locking function.

[0045] Exemplarily, the rotary cylinder has a self-locking function.

[0046] Exemplarily, the motor is a worm gear reduction motor.

[0047] Exemplarily, the body assembly 1 includes a handle and a housing connected to the handle. The driver 2 is mounted on the housing, and the mounting bracket 3 is rotatably connected to the housing.

[0048] Exemplarily, the first axis 31 and the second axis 41 are parallel.

[0049] Exemplarily, the cleaning device may be a mopping machine or an all-in-one washing and mopping machine, etc., and may also be applied to a sweeping machine.

[0050] In the embodiment of the present application, since the first axis 31 and the second axis 41 are arranged at intervals, the cleaning member 4 and the mounting frame 3 are arranged eccentrically. When the driver 2 drives the mounting frame 3 to rotate, the rotating mounting frame 3 will drive the eccentrically arranged cleaning member 4 to rise and fall, so that the cleaning member 4 of the cleaning device can be lowered to contact with the ground according to actual needs to meet the cleaning needs of the cleaning device for the ground under the cleaning condition, and can also be raised to be separated from the ground according to actual needs to meet the cleaning device to reduce the pollution of the cleaned ground under the transfer condition. Therefore, the cleaning device drives the mounting frame 3 to drive the cleaning member 4 to rise and fall through the driver 2, which can meet multiple different use conditions of the cleaning device. In addition, when the cleaning device passes over the carpet, the driver 2 can drive the mounting frame 3 to drive the cleaning member 4 to rise and lift off the carpet, which can reduce the degree to which the cleaning member 4 wets the carpet.

[0051] It can be understood that the cleaning member 4 and the mounting frame 3 are eccentrically arranged, and the cleaning member 4 can be lifted and lowered by rotating the mounting frame 3 on which the cleaning member 4 is mounted. There is no need to provide an additional lifting structure outside the mounting frame 3, which is beneficial to reducing the cost and volume of the cleaning equipment.

[0052] In one embodiment, the cleaning device further includes a roller brush. When the cleaning device passes over the carpet, the driver 2 drives the mounting frame 3 to drive the cleaning member 4 to be lifted off the carpet, and the carpet is cleaned by the roller brush.

[0053] In one embodiment, please refer to Figure 1 and Figure 2 , the distance between the first axis 31 and the second axis 41 is greater than or equal to 3 mm.

[0054] For example, see Figure 1 and Figure 2 , the distance between the first axis 31 and the second axis 41 is D1, D1 ≥ 3 mm.

[0055] For example, see Figure 1 and Figure 2 The distance between the first axis 31 and the second axis 41 may be 3 mm, 5 mm, 7 mm, 11 mm, 15 mm, 20 mm or 22 mm.

[0056] In the embodiment of the present application, the distance between the first axis 31 and the second axis 41 is arranged so that the rotating mounting frame 3 can drive the cleaning member 4 to be lifted to a greater extent, so that the cleaning member 4 can be lifted off the ground as much as possible.

[0057] In one embodiment, please refer to Figure 1 and Figure 2 , the distance between the first axis 31 and the second axis 41 may be 10 mm.

[0058] In the embodiment of the present application, the distance between the first axis 31 and the second axis 41 is relatively appropriate, which can not only lift the cleaning member 4 off the ground to a suitable height, but also make the space occupied by the cleaning device as a whole within a reasonable range.

[0059] It is understandable that the distance between the first axis 31 and the second axis 41 is not limited and can be set according to actual needs.

[0060] In one embodiment, please refer to Figure 1 and Figure 7 The mounting frame 3 includes a mounting body 32 and a cover 33. The mounting body 32 is rotatably connected to the fuselage assembly 1, and both ends of the cleaning member 4 are arranged on the mounting body 32. The cleaning member 4 is rotatably connected to the mounting body 32, and the driver 2 is used to drive the mounting frame 3 to rotate. The cover 33 is connected between the mounting bodies 32 at both ends, and the cover 33 is at least partially located on the side of the second axis 41 along the radial direction of the cleaning member 4 toward the first axis 31. The cover 33 and the mounting bodies 32 at both ends are surrounded by a receiving cavity 34, and the cleaning member 4 is partially located in the receiving cavity 34.

[0061] It should be explained that the cleaning member 4 rotates around the second axis 41 , the central axis of the cylindrical reference surface coincides with the second axis 41 , and the radial direction of the cleaning member 4 is the radial direction of the corresponding cylindrical reference surface.

[0062] For example, see Figure 1 to Figure 6 The cleaning member 4 is a roller, and the radial direction of the cleaning member 4 is the radial direction of the roller.

[0063] For explanation, see Figure 1 and Fig. 9 The cleaning member 4 rotates around the second axis 41 , and the axial direction of the cleaning member 4 is the direction in which the second axis 41 extends.

[0064] Exemplarily, the cross section of the housing 33 is arc-shaped.

[0065] Exemplarily, the cover 33 is a plate-shaped structure.

[0066] In the embodiment of the present application, the driver 2 drives the installation body 32 to rotate and drive the cleaning part 4 to rise and fall to meet multiple working conditions of the cleaning equipment. The cover shell 33 between the installation bodies 32 at both ends rotates around the circumference of the cleaning part 4 driven by the installation body 32. Since the cover 33 is at least partially located on the side of the second axis 41 that faces the first axis 31 along the radial direction of the cleaning member 4, when the cleaning member 4 descends to contact the ground, the second axis 41 is approximately below the first axis 31, and the cover 33 is at least partially above the first axis 31. The sewage thrown out by the cleaning member 4 during the rotation and mopping process is blocked by the cover 33, which can reduce the possibility of the sewage thrown out by the cleaning member 4 splashing onto the fuselage assembly 1 as much as possible, which is beneficial to reducing the pollution of the fuselage assembly 1 by the cleaning member 4. When the cleaning member 4 rises to be separated from the ground or the carpet, the second axis 41 is approximately above the first axis 31, and the cover 33 is at least partially below the first axis 31, so that the cover 33 is at least partially located below the cleaning member 4 to hold the cleaning member 4. In the process of the cleaning device being transferred to the base station or passing through the carpet, even if water drops from the cleaning member 4, it will be held by at least part of the cover 33 below the cleaning member 4, which can reduce the possibility of the cleaning member 4 wetting the carpet and reduce the possibility of the sewage and other dirt on the cleaning member 4 polluting the ground.

[0067] It is understandable that the specific structure of the mounting frame 3 is not limited. Exemplarily, the mounting frame 3 includes mounting bodies 32 at both ends of the cleaning member 4 , but does not include a cover shell 33 .

[0068] In one embodiment, please refer to Figure 3 , Figure 5 and Fig. 9 The mounting frame 3 has a trigger portion 35, which is located on the side of the mounting frame 3 radially away from the cleaning member 4. The cleaning device also includes a trigger switch 5. The trigger portion 35 can rotate with the mounting frame 3 to a position where the trigger switch 5 is triggered so that the trigger switch 5 generates a signal that the mounting frame 3 is rotated to the extreme position.

[0069] Exemplarily, the trigger switch 5 may be a push switch, and when the trigger portion 35 is located at a position to trigger the trigger switch 5 , the trigger portion 35 abuts against the trigger switch 5 .

[0070] Exemplarily, the trigger switch 5 may be a proximity switch. When the trigger portion 35 is located at a position to trigger the trigger switch 5 , the trigger portion 35 is spaced a certain distance from the trigger switch 5 , and the trigger portion 35 is not in contact with the trigger switch 5 .

[0071] Exemplarily, the trigger switch 5 may be an optical coupler detection switch or an infrared detection switch, etc. When the trigger portion 35 is located at the position to trigger the trigger switch 5 , the trigger portion 35 is spaced a certain distance from the trigger switch 5 , and the trigger portion 35 does not contact the trigger switch 5 .

[0072] Exemplarily, the triggering portion 35 is block-shaped.

[0073] In the embodiment of the present application, the trigger unit 35 follows the rotation of the mounting bracket 3 to the position where the trigger switch 5 is triggered, so that the trigger switch 5 generates a signal that the mounting bracket 3 is rotated to the extreme position. The controller can stop the driver 2 according to the signal generated by the trigger switch 5, so that the driver 2 drives the mounting bracket 3 to rotate to the appropriate position and stops, which is beneficial to protecting the mounting bracket 3 and the body assembly 1 and reducing damage between the mounting bracket 3 and the body assembly 1.

[0074] In one embodiment, please refer to Figure 3 and Figure 5 The trigger switch 5 includes a signal generator 51 and a probe rod installed on the signal generator 51. The trigger part 35 has a trigger surface 351 for abutting against the probe rod. When the trigger surface 351 abuts against the probe rod, the trigger surface 351 and the probe rod are arranged crosswise, and the trigger surface 351 is approximately perpendicular to the axial direction of the probe rod or forms a certain angle.

[0075] It should be noted that the trigger surface 351 is perpendicular to the axial direction of the probe rod, and the trigger surface 351 is a plane.

[0076] Exemplarily, there are two disconnected nodes on the signal generator 51 , and the probe rod is electrically connected to the two disconnected nodes on the signal generator 51 respectively, so that the two nodes of the signal generator 51 are turned on, so that the signal generator 51 generates a signal.

[0077] In the embodiment of the present application, the trigger surface 351 pushes the probe rod to be extended or retracted so that the signal generator 51 generates a signal that the mounting frame 3 is rotated to the extreme position. The trigger surface 351 is arranged crosswise with the probe rod. The trigger surface 351 is approximately perpendicular to or at a certain angle to the axis of the probe rod. The direction of the force exerted by the trigger surface 351 on the probe rod is approximately along the extension and retraction direction of the probe rod, which is conducive to the trigger surface 351 smoothly pushing the probe rod to be extended or retracted.

[0078] It is understandable that the trigger surface 351 may not be perpendicular to the axial direction of the probe rod, and the trigger surface 351 may form an acute angle or an obtuse angle with the axial direction of the probe rod.

[0079] In one embodiment, please refer to Figure 3 and Figure 5The trigger portion 35 is in the shape of a plate, and there are multiple trigger switches 5. The probe rod of at least one of the trigger switches 5 is a first probe rod 521, and the first probe rod 521 has a first contact surface 5211 that abuts against the trigger surface 351. The probe rod of at least one of the trigger switches 5 is a second probe rod 522. The second probe rod 522 and the first probe rod 521 are arranged along the circumference of the cleaning member 4. The first probe rod 521 is located on one side of the cleaning member 4 along a preset direction, and the preset direction is respectively arranged to cross the axial direction and the up and down direction of the cleaning member 4. The second probe rod 522 is located on the other side of the cleaning member 4 along the preset direction. The second probe rod 522 has a second contact surface 5221 that abuts against the trigger surface 351. The first contact surface 5211 or the second contact surface 5221 coincides with the second axis 41. The distance between the first contact surface 5211 and the second contact surface 5221 is equal to the thickness of the trigger portion 35 in the shape of a plate.

[0080] It should be noted that the coincidence of the first contact surface 5211 or the second contact surface 5221 with the second axis 41 means that the plane where the first contact surface 5211 is located coincides with the second axis 41 , or the plane where the second contact surface 5221 is located coincides with the second axis 41 .

[0081] In the embodiment of the present application, the first contact surface 5211 or the second contact surface 5221 coincides with the second axis 41, and the distance between the first contact surface 5211 and the second contact surface 5221 is equal to the thickness of the trigger portion 35 in a flat plate shape. When the trigger portion 35 rotates from contacting one of the first contact surface 5211 and the second contact surface 5221 to contacting the other of the first contact surface 5211 and the second contact surface 5221, the trigger portion 35 rotates approximately 180 degrees, and the height difference between the first contact surface 5211 and the second contact surface 5221 just leaves a space for arranging the trigger portion 35 approximately along the thickness direction of the trigger portion 35. The trigger portion 35 is formed on the mounting frame 3, and the trigger portion 35 rotates approximately 180 degrees, that is, the mounting frame 3 rotates approximately 180 degrees, which basically enables the cleaning member 4 to switch between the highest position and the lowest position more accurately.

[0082] It is understandable that the arrangement of the trigger switch 5 is not limited. Exemplarily, when the trigger portion 35 rotates from contacting one of the first contact surface 5211 and the second contact surface 5221 to contacting the other of the first contact surface 5211 and the second contact surface 5221, the angle of rotation of the cover 33 can be 145 degrees.

[0083] In one embodiment, please refer to Figure 3 and Figure 5 , the first contact surface 5211 or the second contact surface 5221 is parallel to the horizontal plane, and the distance between the first contact surface 5211 and the second contact surface 5221 is the height difference between the first contact surface 5211 and the second contact surface 5221 .

[0084] For example, see Figure 3 and Figure 5 , the first contact surface 5211 is parallel to the horizontal plane.

[0085] For example, see Figure 3 and Figure 5 , the first contact surface 5211 is parallel to the horizontal plane. When the trigger portion 35 contacts the first contact surface 5211, the cover 33 is at least partially located below the cleaning member 4, and can hold the water dripping from the cleaning member 4, reduce the pollution of the cleaning member 4 to the ground or carpet, and reduce the degree of wetting of the carpet by the cleaning member 4. When the trigger portion 35 contacts the second contact surface 5221, the cover 33 is at least partially located above the cleaning member 4, and can to a certain extent block the water splashed by the cleaning member 4 during the rotation and mopping process, and reduce the pollution of the body assembly 1 by the water thrown out by the cleaning member 4.

[0086] In the embodiment of the present application, the first contact surface 5211 or the second contact surface 5221 is parallel to the horizontal plane, and the distance between the first contact surface 5211 and the second contact surface 5221 is the height difference between the first contact surface 5211 and the second contact surface 5221. Since the distance between the first contact surface 5211 and the second contact surface 5221 is equal to the thickness of the flat trigger portion 35, the height difference between the first contact surface 5211 and the second contact surface 5221 is equal to the thickness of the flat trigger portion 35. The installation heights of the trigger switches 5 on both sides are relatively close, and the trigger switches 5 on both sides can be roughly installed at a position above the cleaning member 4 of the fuselage assembly 1, which is convenient for folding the trigger switches 5.

[0087] In one embodiment, please refer to Figure 1 to Figure 6 When the driver 2 drives the mounting bracket 3 to rotate in a first direction so that the cleaning member 4 rotates to an ascending state, the trigger portion 35 is located at a position corresponding to one of the trigger switches 5 being triggered to generate a signal that the mounting bracket 3 rotates to an extreme position in the first direction. When the driver 2 drives the mounting bracket 3 to rotate in a second direction so that the cleaning member 4 rotates to a descending state, the second direction is opposite to the first direction. The trigger portion 35 is located at a position corresponding to another trigger switch 5 being triggered to generate a signal that the mounting bracket 3 rotates to an extreme position in the second direction.

[0088] It should be explained that the first direction and the second direction are the directions in which the driver 2 drives the mounting frame 3 to rotate. The driver 2 drives the mounting frame 3 to rotate along the first direction to make the cleaning member 4 rise, and the driver 2 drives the mounting frame 3 to rotate along the second direction to make the cleaning member 4 descend.

[0089] For example, see Figure 3 to Figure 6 , the first direction is the direction indicated by the arrow R2 in the figure.

[0090] For example, see Figure 3 to Figure 6 , the second direction is the direction indicated by arrow R3 in the figure.

[0091] In the embodiment of the present application, the driver 2 drives the mounting frame 3 to rotate in the first direction so that the trigger part 35 triggers the corresponding trigger switch 5, and the trigger switch 5 generates a corresponding signal, thereby making it clear that the mounting frame 3 rotates to the limit position in the first direction, the corresponding cleaning member 4 rises to the limit position, and the cleaning member 4 rotates to the raised state. The driver 2 drives the mounting frame 3 to rotate in the second direction so that the corresponding trigger part 35 triggers the trigger switch 5, and the trigger switch 5 generates a corresponding signal, thereby making it clear that the mounting frame 3 rotates to the limit position in the second direction, the corresponding cleaning member 4 descends to the limit position, and the cleaning member 4 rotates to the descended state. By triggering the corresponding trigger switch 5, the state of the cleaning member 4 can be made clear.

[0092] In one embodiment, please refer to Figure 4 , Figure 6 , Figure 7 and Figure 8 A limiting portion 11 is provided at at least one end of the body assembly 1 along the axial direction of the cleaning member 4 , and the mounting frame 3 has a limiting rib 36 . When the trigger portion 35 is located at a position to trigger the trigger switch 5 , the limiting portion 11 abuts against the corresponding limiting rib 36 .

[0093] For example, see Figure 7 and Figure 8 The limiting portion 11 and / or the limiting rib 36 are block-shaped.

[0094] For example, see Figure 7 The limiting rib 36 is formed on the installation body 32 .

[0095] In the embodiment of the present application, the abutment between the limiting portion 11 and the limiting rib 36 can alleviate the impact of the trigger portion 35 on the trigger switch 5, which is beneficial to protecting the trigger switch 5.

[0097] In the embodiment of the present application, the limiting parts 11 at both ends abut against the corresponding limiting ribs 36, so that the two ends of the cleaning member 4 are evenly stressed, which can better alleviate the impact of the trigger part 35 between the limiting parts 11 on both sides on the trigger switch 5, which is beneficial to protecting the trigger switch 5.

[0098] In one embodiment, please refer to Fig. 9A trigger switch 5 and a corresponding limit portion 11 are provided on opposite sides of the cleaning member 4 along a preset direction.

[0099] For example, see Figure 3 to Figure 6 , the preset direction is the direction indicated by arrow R4 in the figure.

[0100] In the embodiment of the present application, the abutment between the limiting portion 11 and the limiting rib 36 on each side can reduce the impact of the trigger portion 35 on the corresponding side on the trigger switch 5, and the trigger switches 5 on the radially opposite sides of the cleaning member 4 can be better protected.

When the cleaning member 4 is in an ascending state, the first axis 31 is located below the second axis 41, and the mounting frame 3 is at least partially located below the cleaning member 4 to collect the liquid dripping downward from the cleaning member 4.

[0103] In the embodiment of the present application, when the cleaning member 4 is in the descending state, the cleaning member 4 cleans the surface to be cleaned below (for example, the ground), and the mounting frame 3 at least partially located above the cleaning member 4 plays a certain shielding role on the liquid splashed by the cleaning member 4, preventing the liquid from splashing onto the fuselage assembly 1. When the cleaning member 4 is in the ascending state, the cleaning member 4 is separated from the surface to be cleaned, and the mounting frame at least partially located below the cleaning member 4 is scooped under the cleaning member 4, preventing water on the cleaning member 4 that is separated from the surface to be cleaned from dripping onto the surface to be cleaned.

[0104] In one embodiment, the cleaning device also includes a sensor arranged on the body assembly 1, and the sensor is used to detect the material of the surface to be cleaned and generate a detection signal based on the material of the surface to be cleaned, and the detection signal is used as a basis for controlling the driver 2 to drive the mounting frame 3 to drive the cleaning member 4 to rise and fall.

[0105] The detection signal is used as a basis for controlling the driver 2 to drive the mounting frame 3 to lift the cleaning member 4 . The controller can control the driver 2 to move so as to lift the cleaning member 4 based on the detection signal.

[0106] In the embodiment of the present application, the material of the surface to be cleaned can be clearly identified through the detection signal of the sensor, so that different lifting actions can be performed according to different materials.

[0107] Illustratively, when it is determined through the detection signal that the material of the surface to be cleaned is carpet, the driver 2 drives the mounting frame 3 to drive the cleaning element 4 to rotate to an ascending state to prevent the carpet from getting wet; when it is determined through the detection signal that the material of the surface to be cleaned is a surface to be cleaned such as the ground that can be wetted with water, the driver 2 drives the mounting frame 3 to drive the cleaning element 4 to rotate to a descending state to clean the surface to be cleaned.

[0108] In one embodiment, the cleaning device is a cleaning robot.

[0109] In one embodiment, please refer to Figure 3 to Figure 6 , the cleaning member 4 is a roller.

[0110] Exemplarily, the drum may be a wet roller for mopping the floor, or may be a dry roller for absorbing water stains on the floor.

[0111] In one embodiment, the cleaning device further comprises a driving device, which is used to drive the cleaning member 4 to rotate, and the self-rotation of the cleaning member 4 around the second axis 41 and the rotation of the cleaning member 4 relative to the mounting frame 3 around the first axis 31 are not mutually exclusive.

[0112] Exemplarily, the driving device may be a motor.

[0113] Exemplarily, the driving device may be an electric motor with a built-in gearbox.

[0114] Exemplarily, the driving device may include a motor and an external gearbox, and the motor transmits power through the external gearbox.

[0115] By way of example, the drive device may be located inside the cleaning element 4 .

[0116] By way of example, the driving device may be located outside the cleaning element 4 .

[0117] Exemplarily, the driving device may be mounted on the mounting frame 3 .

[0118] In the embodiment of the present application, the driver 2 drives the mounting frame 3 to rotate to a lowered state, the driver 2 stops rotating, and the driving device drives the cleaning member 4 to rotate, so that the rotating cleaning member 4 can better clean the surface to be cleaned.
