[0002] The intelligent cleaning device is used to move on the surface to be cleaned, and cleans the surface to be cleaned by using the movement of the cleaning member at the bottom of the cleaning main body relative to the surface to be cleaned. Generally, the cleaning member can be one of a sweeping member or a washing and mopping member, for example, the sweeping member can be a sweeping brush, and the washing and mopping member can be a rolling brush.

[0087] The cleaning device 10 provided in the embodiment of the present application can be controlled according to the method for controlling the cleaning device 10 provided in the present application.

[0088] The cleaning device 10 includes a device body 13, a first cleaning mechanism 11, and a second cleaning mechanism 12. The first cleaning mechanism 11 includes a first cleaning member 112 movably connected to the device body 13, and the second cleaning mechanism 12 includes a second cleaning member 122 movably connected to the device body 13; the first cleaning member 112 and the second cleaning member 122 both have a lifting position and a working position, and can be switched between the lifting position and the working position; wherein the lifting position is higher than the working position.

[0089] Among them, the state in which the first cleaning member 112 is in the raised position and the second cleaning member 122 is in the working position is the first working mode of the cleaning device 10; the state in which the first cleaning member 112 is in the working position and the second cleaning member 122 is in the raised position is the second working mode of the cleaning device 10; the state in which the first cleaning member 112 and the second cleaning member 122 are both in the working position is the third working mode of the cleaning device 10; the state in which the first cleaning member 112 and the second cleaning member 122 are both in the raised position is the fourth working mode of the cleaning device 10.

[0090] In the cleaning device 10 provided in the embodiment of the present application, the state in which the first cleaning member 112 is in the raised position and the second cleaning member 122 is in the working position is the first working mode of the cleaning device 10; the state in which the first cleaning member 112 is in the working position and the second cleaning member 122 is in the raised position is the second working mode of the cleaning device 10; the state in which the first cleaning member 112 and the second cleaning member 122 are both in the working position is the third working mode of the cleaning device 10; the state in which the first cleaning member 112 and the second cleaning member 122 are both in the raised position is the fourth working mode of the cleaning device 10. The cleaning device 10 not only has the first working mode, the second working mode, the third working mode and the fourth working mode, but also can switch between any working modes. When the cleaning device 10 tends to develop in the direction of comprehensive functions such as sweeping, mopping and washing, it can satisfy the control of multiple cleaning members of the cleaning device 10 to achieve switching of multiple working modes.

[0091] Furthermore, the first cleaning mechanism 11 further includes a first lifting mechanism 111, and the first cleaning member 112 is disposed on the first lifting mechanism 111. The second cleaning mechanism 12 further includes a second lifting mechanism 121, and the second cleaning member 122 is disposed on the second lifting mechanism 121. Moreover, the first lifting mechanism 111 and the second lifting mechanism 121 are respectively movably connected to the device body 13 and can be changed in height relative to the device body 13, so as to respectively drive the first cleaning member 112 and the second cleaning member 122 to rise and fall relative to the device body 13.

[0092] Furthermore, the device body 13 is provided with a control unit for controlling at least one of the first cleaning member 112 and the second cleaning member 122 to switch between the lifting position and the working position through the first lifting mechanism 111 and the second lifting mechanism 121 respectively.

[0093] The following is combined with Figure 1-Figure 32 The cleaning device 10 and the method for controlling the cleaning device 10 provided in the embodiment of the present application are described.

[0094] The cleaning mechanism mentioned separately below may refer to the first cleaning mechanism 11 or the second cleaning mechanism 12, or to the first cleaning mechanism 11 and the second cleaning mechanism 12. The cleaning member mentioned separately below may refer to the first cleaning member 112 or the second cleaning member 122, or to the first cleaning member 112 and the second cleaning member 122. The swing assembly 101, the lifting assembly 102, and the lifting frame 1027 mentioned separately below may belong to the first lifting mechanism 111 or the second lifting mechanism 121, or the first lifting mechanism 111 and the second lifting mechanism 121 have the same structure, and they respectively have the swing assembly 101, the lifting assembly 102, and the lifting frame 1027.

[0095] Reference Figures 1 to 32 As shown, the cleaning device 10 provided in the embodiment of the present application includes a device body 13, and a first cleaning mechanism 11 and a second cleaning mechanism 12. The first cleaning mechanism 11 includes a first lifting mechanism 111 and a first cleaning member 112 configured on the first lifting mechanism 111, and the second cleaning mechanism 12 includes a second lifting mechanism 121 and a second cleaning member 122 configured on the second lifting mechanism 121. Moreover, the first lifting mechanism 111 and the second lifting mechanism 121 are respectively movably connected to the device body 13 and can be changed in height relative to the device body 13, so as to respectively drive the first cleaning member 112 and the second cleaning member 122 to rise and fall relative to the device body 13.

[0096] Compared with the prior art, the cleaning device 10 provided in the embodiment of the present application, wherein the first cleaning mechanism 11 includes a first lifting mechanism 111 and a first cleaning member 112 configured on the first lifting mechanism 111, wherein the second cleaning mechanism 12 includes a second lifting mechanism 121 and a second cleaning member 122 configured on the second lifting mechanism 121. The first lifting mechanism 111 and the second lifting mechanism 121 are respectively movably connected to the device body 13, and both can independently change the height relative to the device body 13, and independently drive the first cleaning member 112 and the second cleaning member 122 to rise and fall relative to the device body 13.

[0097] The heights of the first cleaning member 112 and the second cleaning member 122 are adjustable, and the two can work independently, so the cleaning members of the cleaning device 10 can be adjusted according to the specific needs of the scene to be cleaned. For example, the first cleaning member 112 is in a low position for cleaning, while the second cleaning member 122 is in a high position and away from the cleaning ground; or, the second cleaning member 122 is in a low position for cleaning, while the first cleaning member 112 is in a high position and away from the cleaning ground; or, the first cleaning member 112 and the second cleaning member 122 are both in a low position for cleaning; or, the first cleaning member 112 and the second cleaning member 122 are both in a high position and away from the cleaning ground.

[0098] The cleaning device 10 provided in the embodiment of the present application is respectively configured with an independently adjustable first lifting mechanism 111 and a second lifting mechanism 121 for the first cleaning member 112 and the second cleaning member 122, and the switching adjustment of various working modes is realized through the first lifting mechanism 111 and the second lifting mechanism 121, thereby meeting the user demand that the cleaning device 10 has multiple working modes.

[0099] In some embodiments, the first lifting mechanism 111 and the second lifting mechanism 121 have the same structure, so as to reduce the design cost of the first lifting mechanism 111 and the second lifting mechanism 121. Of course, in other embodiments, on the basis of being able to independently drive the first cleaning member 112 and the second cleaning member 122 to rise and fall, the first lifting mechanism 111 and the second lifting mechanism 121 may have completely different structures, or one part of them may be the same and the other part may be different.

[0100] In some embodiments, the first cleaning member 112 is a sweeping member, and the second cleaning member 122 is a washing and mopping member. The sweeping member refers to a cleaning member that can sweep the cleaned floor, including but not limited to a sweeping brush. The washing and mopping member refers to a cleaning member that can wash or mop the cleaned floor, wherein the difference between washing and mopping is that washing requires providing clean water to the cleaning member, while mopping does not require providing clean water to the cleaning member, and the cleaning member in a dry state is used to mop the cleaned floor to clean the water stains thereon.

[0101] The second cleaning member 122 is a washing and mopping member, and the second cleaning member 122 can have a washing function alone or a mopping function alone. Optimally, the second cleaning member 122 has a washing function and a mopping function, and the control unit on the device body 13 controls whether the clean water tank provides clean water to the second cleaning member 122. When clean water is provided, the washing and mopping member has a washing function, and when the washing and mopping member is dry, it has a mopping function.

[0102] In some other embodiments, the first cleaning member 112 is a sweeping member, and the second cleaning member 122 is also a sweeping member. The difference between the first cleaning member 112 and the second cleaning member 122 is that the sweeping bristles of the cleaning member located at the front side of the device body 13 in the direction of travel can be designed to have a larger spacing or a thicker diameter, so as to facilitate the cleaning member located at the front side to first clean up the garbage with larger particles on the cleaning ground. The sweeping bristles of the cleaning member located at the rear side of the device body 13 in the direction of travel can be designed to have a smaller spacing or a thinner diameter, so as to facilitate the cleaning member located at the rear side to perform a secondary fine cleaning on the ground cleaned by the front cleaning member, clean up the garbage with smaller particles on the cleaning ground, and fully sweep and clean the cleaning ground with sweeping bristles of different spacing or different thicknesses.

[0103] In some other embodiments, the first cleaning member 112 is a floor scrubber, and the second cleaning member 122 is a floor mopping member. The difference between the first cleaning member 112 and the second cleaning member 122 is that the cleaning member located at the front side of the device body 13 in the direction of travel is a floor scrubber, which has a floor scrubbing function under the condition of providing clean water, so that the cleaning member located at the front side can first scrub the cleaned floor. The cleaning member located at the rear side of the device body 13 in the direction of travel is a floor mopping member, which has a floor mopping function under the condition of drying the floor mopping member, so that the cleaning member located at the rear side can dry the floor cleaned by the front cleaning member, and the two cleaning members with floor scrubbing and floor mopping functions can complete the high cleanliness of the cleaned floor by washing and mopping.

[0104] In some embodiments, along the moving direction of the device body 13, the first lifting mechanism 111 and the second lifting mechanism 121 are arranged in parallel and spaced apart, and the first cleaning member 112 and the second cleaning member 122 are arranged in parallel and spaced apart, which is beneficial for the first cleaning mechanism 11 and the second cleaning mechanism 12 to be conveniently arranged along the moving direction of the device body 13.

[0105] In other embodiments, at least one of the first lifting mechanism 111 and the second lifting mechanism 121 can have a slight angle with the direction of travel, and at least one of the first cleaning member 112 and the second cleaning member 122 can have a slight angle with the direction of travel, which does not affect the implementation and completion of the functions of the first cleaning mechanism 11 and the second cleaning mechanism 12.

[0106] The bottom cover 133 is used to cover the lower side of the device body 13 and can be detached or installed on the device body 13 .

[0107] In some embodiments, the lifting mechanism includes a swing assembly 101 and a lifting assembly 102, and the lifting assembly 102 includes a cleaning member. The swing assembly 101 is rotatably connected to the device body 13, and the lifting assembly 102 is connected to a side of the swing assembly 101 away from the device body 13. When the swing assembly 101 rotates relative to the device body 13, the height of the lifting assembly 102 relative to the device body 13 is allowed to be variable.

[0108] Compared with making the lifting component 102 directly lift in a straight line along the height direction, the height of the lifting component 102 can be changed by rotating the swing component 101 relative to the equipment body 13, that is, the entire cleaning mechanism can occupy some space in the direction of travel, avoiding lifting in a straight line along the height direction and requiring the cleaning mechanism to occupy too much size in the height direction. Since the space of the cleaning device 10 along the height direction is relatively limited, it is not conducive to configuring most of the components of the cleaning mechanism along the height direction.

[0109] Of course, when the size of the cleaning device 10 in the height direction is relatively sufficient, the cleaning mechanism can be designed to be lifted and lowered directly in a straight line in the height direction.

[0110] In some embodiments, the first lifting mechanism 111 and the second lifting mechanism 121 both include a swing assembly 101 and a lifting assembly 102. Figure 1 and Figure 2 As shown, along the travel direction of the device body 13, the two swing components 101 are respectively arranged on the two opposite sides of the two lifting components 102. Figures 3 to 8 As shown, along the moving direction of the device body 13 , the two swing assemblies 101 are respectively arranged on the same side of the two lifting assemblies 102 .

[0111] The two swing assemblies 101 are respectively arranged on two opposite sides of the two lifting assemblies 102, that is, the rotation axes of the first cleaning mechanism 11 and the second cleaning mechanism 12 are arranged on two opposite sides of the two lifting assemblies 102, and will not interfere with each other. Compared with the solution in which the two swing assemblies 101 are respectively arranged on two opposite sides of the two lifting assemblies 102, the two swing assemblies 101 are respectively arranged on the same side of the two lifting assemblies 102, which can reduce the occupation of the space extending along the travel direction and reduce the total occupation space of the first cleaning mechanism 11 and the second cleaning mechanism 12 on the cleaning device 10.

[0112] In some embodiments, the swing assembly 101 includes a first swing member 1011 and a second swing member 1012, and the lifting assembly 102 includes a driving member 1021 having a driving shaft 1021a, and the driving shaft 1021a is transmission-connected to the cleaning member. The first end 1011a of the first swing member 1011 is rotationally connected to the device body 13, and the second end 1011b away from the first end 1011a is connected to the lifting assembly 102. The first head 1012a of the second swing member 1012 is movably connected to the device body 13 and has a lifting position relative to the device body 13, and the second head 1012b away from the first head 1012a can be transmission-connected to the driving shaft 1021a. The second swinging member 1012 is configured such that when the driving shaft 1021a drives the first head 1012a through the second head 1012b to be in the raised position, the first swinging member 1011 is fixed relative to the device body 13, so that the lifting assembly 102 is in the raised position, and is configured such that when the driving shaft 1021a drives the first head 1012a through the second head 1012b to be out of the raised position, the first swinging member 1011 is rotatable relative to the device body 13, so that the lifting assembly 102 is lowered from the raised position to the working position.

[0113] The device body 13 is fixed, the first end 1011a of the first swing member 1011 is rotatably connected to the device body 13, and the first swing member 1011 rotates around the first end 1011a, so the first swing member 1011 can be understood as a fixed-axis swing member. Since the cleaning mechanism as a whole can be raised and lowered relative to the device body 13, the second head 1012b of the second swing member 1012 can be transmission-connected to the drive shaft 1021a, and the drive shaft 1021a is part of the lifting assembly 102, so the central axis of the second head 1012b of the second swing member 1012 can be raised and lowered, so the second swing member 1012 can be understood as a dynamic-axis swing member.

[0114] The driving member 1021 can be a driving motor, and the driving shaft 1021a provides the motive force for the rotational cleaning of the cleaning member and the lifting of the cleaning mechanism. The driving shaft 1021a drives the first head 1012a to move relative to the device body 13 through the second head 1012b. In one aspect, when the first head 1012a moves to the lifting position, the rotation angle of the first swinging member 1011 relative to the device body 13 is fixed, so that the lifting assembly 102 is in the lifting position, and the cleaning mechanism is in the lifting position as a whole. On the other hand, when the first head 1012a is out of the lifting position, the first head 1012a loses the restriction on the first swinging member 1011, that is, the angle of the first swinging member 1011 relative to the device is converted from a fixed state to a released state, and the first swinging member 1011 is rotatable relative to the device body 13, so that the lifting assembly 102 is lowered from the lifting position to the working position.

[0115] In this part, the driving shaft 1021a drives the first head 1012a through the second head 1012b to move the first head 1012a to the raised position and keep the first head 1012a in the raised position. At this time, since the cleaning member is in the raised position, the cleaning member does not need to work, so the driving shaft 1021a can be in a stationary state.

[0116] Therefore, in one embodiment, the driving shaft 1021a may be continuously supplied with power, so that the driving shaft 1021a maintains the first head 1012a in the raised position, thereby maintaining the entire cleaning mechanism in the raised position.

[0117] In another embodiment, the second swing member 1012 is configured such that when the first head 1012a is in the raised position, the first head 1012a, the second head 1012b, and the first end 1011a are respectively located at the three vertices of the same triangle to form a self-locking. The triangle has stability, so the three vertices of the same triangle can form a self-locking balance and remain stationary, that is, when the first head 1012a, the second head 1012b, and the first end 1011a are respectively located at the three vertices of the same triangle, they can be kept in the raised position by pure mechanical force until the drive shaft 1021a rotates and breaks the self-locking balance again. In this embodiment, the drive shaft 1021a can also be continuously supplied with power, so that the cleaning mechanism is kept in the raised position by electricity and mechanical force.

[0118] like Figure 5 and Figure 6 As shown, optionally, the first head 1012a and the first end 1011a are located on the same side of the height plane where the second head 1012b is located. Optionally, the first head 1012a and the first end 1011a can also be located on both sides of the height plane where the second head 1012b is located. Wherein, the height plane refers to the vertical plane where the central axis of the second head 1012b is located. Compared with the solution in which the first head 1012a and the first end 1011a are located on both sides of the height plane where the second head 1012b is located, the first head 1012a and the first end 1011a are located on the same side of the height plane where the second head 1012b is located, and the stability of the triangle formed by them is better, which is more conducive to stably maintaining the cleaning mechanism in the raised position.

[0119] In some embodiments, the driving shaft 1021a and the cleaning member are arranged in parallel from top to bottom. The first swing member 1011 and the second swing member 1012 are arranged on the same side of the height plane where the driving shaft 1021a and the cleaning member are located, which is beneficial to the overall stability of the swing assembly 101 and reduces the size occupied by the swing assembly 101 along the travel direction. The first swing member 1011 and the second swing member 1012 are staggered along the axis of the driving shaft 1021a to prevent the first swing member 1011 and the second swing member 1012 from interfering with each other during the lifting process.

[0120] In some embodiments, reference Figure 20 to Figure 24 As shown, the device body 13 is configured with a slideway structure 131, which extends horizontally along the travel direction of the device body 13, and the first head 1012a is slidably configured in the slideway structure 131. When the first head 1012a is located at the extreme position of the slideway structure 131 close to the second head 1012b, the first head 1012a is located in a raised position.

[0121] When the first head 1012a is located at the extreme position of the slideway structure 131 close to the second head 1012b, the first head 1012a is located at the lifting position. At this time, the first head 1012a has no space to continue sliding. The first head 1012a is against the extreme position of the slideway structure 131 close to the second head to form a tight state. At this time, the motor stops rotating, and the position of the second head 1012b remains fixed, so that the first head 1012a, the second head 1012b, and the first end 1011a are respectively located at the three vertices of the same triangle and form a self-locking. At this time, the cleaning mechanism is in the lifting position as a whole. Among them, when the first head 1012a is out of the lifting position, the first head 1012a can slide freely in other areas of the slideway structure 131 outside the extreme position close to the second head 1012b.

[0122] It should be noted that the extension length of the slide structure 131 along the travel direction can be flexibly designed. The longer the extension length of the slide structure 131 is, the longer the length space allowed for the first head 1012a to slide, that is, the longer the swing space of the second swing member 1012 is, which allows the angle between the second swing member 1012 and the slide structure 131 to be infinitely smaller. In this way, the lifting height of the lifting assembly 102 can be adjusted, and the lifting height of the lifting assembly 102 can be flexibly adjusted according to the height of the equipment body 13, and the lifting height can be increased or reduced.

[0123] Reference Fig. 9 and Fig.19 As shown, in some embodiments, the lifting assembly 102 further includes a one-way bearing 1023, which is disposed on the transmission path of the drive shaft 1021a and the second head 1012b. The one-way bearing 1023 is configured to allow the drive shaft 1021a to drive the second head 1012b to move relative to the device body 13 when the drive shaft 1021a rotates in the first direction, and is configured to prevent the drive shaft 1021a from driving the second head 1012b when the drive shaft 1021a rotates in the second direction. The first direction and the second direction are opposite.

[0124] The one-way bearing 1023 allows the shaft member sleeved therein to rotate in one direction, and can lock the shaft member in another direction opposite to the one direction, thereby preventing the shaft member from rotating in the other direction. The one-way bearing 1023 is also called an overrunning clutch. A plurality of rollers, needle rollers or balls are mounted in the one-way bearing 1023. The shape of the rolling seat of the one-way bearing 1023 only allows the rollers, needle rollers or balls therein to roll in one direction, while generating a large resistance in the other direction, thereby achieving the above-mentioned purpose.

[0125] In some embodiments, the lifting assembly 102 further includes a camshaft 1022 and a cam 1024. The camshaft 1022 is in transmission connection with the drive shaft 1021a, and the cam 1024 is sleeved on the camshaft 1022 via a one-way bearing 1023. The second head 1012b is rotatably connected to the camshaft 1022, and the rotation axis of the second head 1012b is spaced apart from the rotation axis of the camshaft 1022.

[0126] The cam 1024 refers to a wheel body provided with a convex portion 1024a, wherein the convex portion 1024a is provided on the outer periphery of the wheel body. When the cam 1024 rotates around its central axis, the convex portion 1024a is synchronously driven to rotate axially, so the position of the convex portion 1024a changes with the rotation of the wheel body.

[0127] Specifically, in some embodiments, the first direction may be counterclockwise, and the second direction may be clockwise. Figure 29 to Figure 31 As shown, in one aspect, the driving shaft 1021a drives the camshaft 1022 to rotate along the first direction, and the one-way bearing 1023 allows the driving shaft 1021a to drive the camshaft 1022 along the first direction, so that the camshaft 1022 can drive the cam 1024 to rotate along the first direction. The second head 1012b is in transmission connection with the camshaft 1022, and the rotation axis of the second head 1012b is spaced from the rotation axis of the camshaft 1022, then the second head 1012b is driven by the camshaft 1022, so that the second head 1012b moves around the central axis of the cam 1024, and the movement trajectory of the second head 1012b is located outside the central axis of the cam 1024. At this time, the triangular self-locking formed by the first head 1012a, the second head 1012b and the first end 1011a is broken, the first swinging member 1011 rotates downward relative to the device body 13, and the lifting assembly 102 switches from the lifting position to the working position.

[0128] In between Fig.31 and Fig.32 The working process is as follows: after the lifting assembly 102 is switched to the working position, the drive shaft 1021a switches to rotate in the second direction, and the drive shaft 1021a drives the cleaning member to perform cleaning work in the second direction. During this process, the drive shaft 1021a drives the cam shaft 1022 to rotate in the second direction, and the one-way bearing 1023 does not allow the drive shaft 1021a to drive the cam shaft 1022 in the second direction, so the cam shaft 1022 cannot drive the cam 1024 to rotate in the second direction. At this time, the cam 1024 is in a roughly natural state due to the action of gravity, and its convex part 1024a is located at the bottom. After the cleaning member completes the cleaning work, the drive shaft 1021a stops rotating in the second direction, and switches the rotation direction to rotate in the first direction.

[0129] Reference Fig.32As shown, on the other hand, the driving shaft 1021a drives the camshaft 1022 again along the first direction, the camshaft 1022 drives the cam 1024, the cam 1024 drives the second head 1012b of the second swinging member 1012 to move, and the second head 1012b drives the first head 1012a to start moving toward the above-mentioned extreme position of the slide structure 131, and when the driving shaft 1021a stops rotating along the first direction, the rotation angle of the cam 1024 is fixed, and the first head 1012a just moves to the above-mentioned extreme position of the slide structure 131, that is, the driving shaft 1021a drives the lifting assembly 102 to switch from the working position to the lifting position again, and after lifting, the first head 1012a, the second head 1012b and the first end 1011a re-form a triangle for self-locking, thereby keeping the lifting assembly 102 in the lifting position.

[0130] In some embodiments, the lifting assembly 102 further includes an elastic member 1028b, which is disposed beside the cam 1024 and extends radially along the cam 1024. The cam 1024 is configured such that the first head 1012a is located in the lifting position when its protrusion 1024a abuts against the elastic member 1028b and remains fixed, and is configured to overcome the elastic force of the elastic member 1028b under the driving of the driving shaft 1021a along the first direction, and drive the first head 1012a to leave the lifting position through the second head 1012b, and is configured to continue to rotate under the driving of the driving shaft 1021a along the first direction and abut against the elastic member 1028b again, and drive the first head 1012a to move to the lifting position again through the second head 1012b.

[0131] The elastic member 1028b serves to keep the protrusion 1024a of the cam 1024 in a fixed position through elastic force, and the cam 1024 can overcome the elastic force and leave the fixed position when the driving shaft 1021a is driven along the first direction.

[0132] Specifically, refer to Figures 14 to 19As shown, the lifting assembly 102 includes a lifting frame body 1027, and all the components of the lifting assembly 102 that can be driven to lift by the swing assembly 101 are arranged on the lifting frame body 1027. A limit assembly 1028 is arranged on the lifting frame body 1027, and the limit assembly 1028 includes a limit bracket 1028d and an elastic member 1028b, and the limit bracket 1028d can be fixed to the lifting frame body 1027 by a screw connection. The limit bracket 1028d is provided with an opening 1028c facing the cam 1024, and a limit member 1028a is movably arranged on the opening 1028c, a part of the limit member 1028a is arranged inside the limit bracket 1028d, and another part of the limit member 1028a is arranged outside the limit bracket 1028d. The elastic member 1028b is movably disposed inside the elastic member 1028b, and the elastic member 1028b is sleeved on the part of the limiting member 1028a located inside the limiting bracket 1028d. The limiting member 1028a can move inward or outward along the opening 1028c, and the limiting member 1028a can compress or relax the elastic member 1028b.

[0133] The above paragraph only provides an optional installation method for one elastic member 1028b. The elastic member 1028b may be assembled using other methods. This embodiment does not impose any specific restrictions on the assembly method of the elastic member 1028b.

[0134] Reference Fig.29 As shown, in the raised position, the convex portion 1024a of the cam 1024 just abuts against the stopper 1028a, and the stopper 1028a supports the convex portion 1024a through the elastic force provided by the elastic member 1028b, so that the convex portion 1024a is kept in this position, that is, the cam 1024 is kept at this angle. At this time, the first head 1012a, the second head 1012b and the first end 1011a form a triangular self-locking, and the lifting assembly 102 is kept in the raised position.

[0135] Reference Figure 29 to Figure 31As shown, in one aspect, the driving shaft 1021a drives the camshaft 1022 to rotate along the first direction, and the camshaft 1022 can drive the cam 1024 to rotate along the first direction. The convex portion 1024a of the cam 1024 overcomes the elastic force of the elastic member 1028b and rotates along the first direction. The second head 1012b is driven by the camshaft 1022, so that the second head 1012b moves around the central axis of the cam 1024, and the movement trajectory of the second head 1012b is located outside the central axis of the cam 1024. At this time, the triangular self-locking formed by the first head 1012a, the second head 1012b and the first end 1011a is broken, the first swinging member 1011 rotates downward relative to the device body 13, and the lifting assembly 102 switches from the lifting position to the working position. Among them, after the convex portion 1024a of the cam 1024 passes over the limiter 1028a, the elastic member 1028b returns to its original position.

[0136] In between Fig.31 and Fig.32 The working process is as follows: after the lifting assembly 102 is switched to the working position, the driving shaft 1021a is switched to rotate along the second direction, and the driving shaft 1021a drives the cleaning member to perform cleaning work along the second direction. During this process, the elastic member 1028b returns to the original position and remains in the original position, and the cam 1024 is in a substantially natural state due to the action of gravity, and its convex portion 1024a is located at the lowest end.

[0137] Reference Fig.32 As shown, on the other hand, the driving shaft 1021a drives the camshaft 1022 again along the first direction, and the camshaft 1022 drives the cam 1024 to rotate back to the position of the limit member 1028a along the first direction, and again leans against the limit member 1028a, and the limit member 1028a re-supports the protrusion 1024a through the elastic force provided by the elastic member 1028b, so that the protrusion 1024a is restricted again. During this process, the cam 1024 drives the second head 1012b of the second swinging member 1012 to move, and the second head 1012b drives the first head 1012a to start moving toward the above-mentioned extreme position of the slide structure 131. When the driving shaft 1021a stops rotating along the first direction, the rotation angle of the cam 1024 is fixed, and the first head 1012a just moves to the above-mentioned extreme position of the slide structure 131, that is, the driving shaft 1021a drives the lifting assembly 102 from the working position to the lifting position again, and after lifting, the first head 1012a, the second head 1012b and the first end 1011a re-form a triangle for self-locking, thereby keeping the lifting assembly 102 in the lifting position.

[0138] In the previous embodiment, the elastic member 1028b and the limit member 1028a are dynamic members. In other embodiments, the limit member 1028 can be replaced by a limit structure 1029 fixed relative to the lifting frame. In the two embodiments, the descending drive process of the lifting assembly 102 is different. In the embodiment using the elastic member 1028b and the limit member 1028a, the drive shaft 1021a provides power along the first direction, thereby driving the lifting assembly 102 to switch from the lifting position to the working position. In the embodiment using the limit structure 1029, the drive shaft 1021a rotates along the second direction to provide an inertial force, and the inertial force serves as a driving force, thereby driving the lifting assembly 102 to switch from the lifting position to the working position. In the two embodiments, the ascending drive process of the lifting assembly 102 is consistent.

[0139] In some other embodiments, the lifting assembly 102 further includes a limiting structure 1029, which is disposed beside the cam 1024 and fixed relative to the cam 1024. The cam 1024 is configured such that when its protruding portion 1024a abuts against the limiting structure 1029 and remains fixed, the first head 1012a is located in the lifting position, and is configured such that when the drive shaft 1021a rotates in the second direction, the cam 1024 is driven by inertia to separate from the limiting structure 1029 in the second direction, so that the cam 1024 drives the first head 1012a to separate from the lifting position through the second head 1012b, and is configured such that when the drive shaft 1021a is driven in the first direction, the cam 1024 rotates in the opposite direction and abuts against the limiting structure 1029 again, and drives the first head 1012a to move to the lifting position again through the second head 1012b.

[0140] Reference Fig.25 As shown, in the lifting position, the convex portion 1024a of the cam 1024 just abuts against the limiting structure 1029, which is fixed and supports the convex portion 1024a, so that the convex portion 1024a is kept in this position, that is, the cam 1024 is kept at this angle. At this time, the first head 1012a, the second head 1012b and the first end 1011a form a triangular self-locking, and the lifting assembly 102 is kept in the lifting position.

[0141] Reference Figure 25 to Figure 27As shown, in one aspect, the driving shaft 1021a drives the camshaft 1022 to rotate along the second direction, and the camshaft 1022 cannot drive the cam 1024 to rotate along the second direction, but can provide driving force through the inertia force generated when the driving shaft 1021a is started, and the inertia force drives the cam 1024 to rotate along the second direction, and the second head 1012b is driven by the camshaft 1022 to move around the central axis of the cam 1024, and the movement trajectory of the second head 1012b is located outside the central axis of the cam 1024. At this time, the triangular self-locking formed by the first head 1012a, the second head 1012b and the first end 1011a is broken, the first swinging member 1011 rotates downward relative to the device body 13, and the lifting assembly 102 switches from the lifting position to the working position.

[0142] In between Fig. 27 and Fig.28 The working process is as follows: the lifting assembly 102 switches to the working position and the driving shaft 1021a continues to rotate in the second direction, and the driving shaft 1021a drives the cleaning member in the second direction to perform cleaning. During this process, the cam 1024 is in a substantially natural state due to gravity, and its convex portion 1024a is located at the lowest end.

[0143] Reference Fig.28 As shown, on the other hand, after the cleaning member completes the cleaning work, the driving shaft 1021a switches the rotation direction and switches from the second direction to the first direction, and re-drives the camshaft 1022. The camshaft 1022 drives the cam 1024 to rotate back along the first direction to the position of the limiting member 1028a, and re-abuts against the limiting structure 1029. The limiting structure 1029 re-supports the protrusion 1024a so that the protrusion 1024a is restricted again. During this process, the cam 1024 drives the second head 1012b of the second swinging member 1012 to move, and the second head 1012b drives the first head 1012a to start moving toward the above-mentioned extreme position of the slide structure 131. When the driving shaft 1021a stops rotating along the first direction, the rotation angle of the cam 1024 is fixed, and the first head 1012a just moves to the above-mentioned extreme position of the slide structure 131, that is, the driving shaft 1021a drives the lifting assembly 102 from the working position to the lifting position again, and after lifting, the first head 1012a, the second head 1012b and the first end 1011a re-form a triangle for self-locking, thereby keeping the lifting assembly 102 in the lifting position.

[0144] In some embodiments, the drive shaft 1021a, the cam shaft 1022 and the cleaning member are arranged in parallel and spaced apart. The drive shaft 1021a, the cam shaft 1022 and the cleaning member are sequentially connected in transmission. Alternatively, the cam shaft 1022 and the cleaning member are respectively connected in transmission to the drive shaft 1021a.

[0145] like Fig.12 , Figures 25 to 32 As shown, the driving shaft 1021a, the cam shaft 1022 and the cleaning member are arranged in parallel and spaced apart, and the driving shaft 1021a, the cam shaft 1022 and the cleaning member are located at three vertices of a triangle. The driving shaft 1021a and the cam shaft 1022 are connected by a first transmission belt 1025, and the cam shaft 1022 and the cleaning member are connected by a second transmission belt 1026.

[0146] In other embodiments, the camshaft 1022 and the cleaning member are respectively connected to the drive shaft 1021a by transmission. For example, the drive shaft 1021a and the camshaft 1022 are connected by transmission through the first transmission belt 1025, the drive shaft 1021a and the cleaning member are connected by transmission through the second transmission belt 1026, and the cleaning member and the camshaft 1022 are not connected by transmission.

[0147] like Fig.14 As shown, the lifting frame body 1027 is equipped with a transmission box 1027a, and the driving shaft 1021a, the camshaft 1022 and the cleaning member are sequentially connected in a transmission manner and arranged in the transmission box 1027a, wherein transmission components such as a support bearing and a synchronous wheel can be arranged. The transmission box 1027a can be provided with a transmission cover 1027b, and the transmission connection part can be repaired or replaced by installing or removing the transmission cover 1027b.

[0148] The second swinging member 1012 may include a main connecting member, the main connecting member having a first head 1012a and a second head 1012b, the first head 1012a is provided with two rollers 1012c, the two rollers 1012c are coaxially connected, the axes of the two rollers 1012c are consistent with the axis of the first head 1012a, the two rollers 1012c may be fixed to the first head 1012a by screws, and the two rollers 1012c may roll in the slideway structure 131. The second head 1012b may be fixed to a portion of the convex portion 1024a away from its central axis by a meson screw 1012d.

[0149] The above paragraph only provides an optional installation method for a second swinging member 1012 . The second swinging member 1012 may be assembled using other methods. This embodiment does not impose any specific restrictions on the assembly method of the second swinging member 1012 .

[0150] In some embodiments, such as Figure 8As shown, the lifting frame 1027 of the lifting assembly 102 in the first lifting mechanism 111 includes a first accommodating structure 1027c and a first channel structure 1027d, and the device body 13 includes a dust box structure. The first accommodating structure 1027c, the first channel structure 1027d and the dust box structure are arranged in sequence from bottom to top. The first accommodating structure 1027c has a first accommodating cavity, and the first accommodating cavity has a top opening and a bottom opening opened on both sides along the height direction. The first channel structure 1027d connects the dust box structure and the top opening, and the first channel structure 1027d is elastic and allows the height of the first accommodating structure 1027c relative to the dust box structure to be variable; the first cleaning member 112 is rotatably arranged in the first accommodating cavity and partially extends out of the bottom opening.

[0151] The dust box structure is used to collect garbage, such as dust, cleaned by the first cleaning member 112. The dust box structure is fixed relative to the device body 13, while the first cleaning member 112 can be raised and lowered relative to the device body 13. Therefore, the channel between the dust box structure and the first cleaning member 112 needs to be designed to be elastic and can be deformed with the lifting and lowering of the first cleaning member 112 to ensure that the first cleaning member 112 can be lifted and lowered normally.

[0152] In some embodiments, the lifting frame 1027 of the lifting assembly 102 in the first lifting mechanism 111 includes a second accommodating structure 1027e and a second channel structure 1027f, the device body 13 includes a sewage tank, and the second accommodating structure 1027e, the second channel structure 1027f and the sewage tank are arranged in sequence from bottom to top. The second accommodating structure 1027e has a second accommodating cavity, and the second accommodating cavity has an upper opening and a lower opening opened on both sides along the height direction. The second channel structure 1027f connects the sewage tank and the upper opening, and the second channel structure 1027f is elastic and allows the height of the second accommodating structure 1027e relative to the sewage tank to be variable; the second cleaning member 122 is rotatably arranged in the second accommodating cavity and partially extends out of the lower opening.

[0153] The sewage tank is used to collect sewage generated by the second cleaning member 122. The sewage tank is fixed relative to the device body 13, while the second cleaning member 122 can be raised and lowered relative to the device body 13. Therefore, the passage between the sewage tank and the second cleaning member 122 needs to be designed to be elastic and deformable with the raising and lowering of the second cleaning member 122 to ensure that the second cleaning member 122 can be raised and lowered normally.

[0154] In some embodiments, the device body 13 is provided with a cleaning mode switching switch and a control unit; wherein, the cleaning mode switching switch can be set on the outer wall of the device body 13, and can be a push button or a push mechanism, and the user can select the mode to be switched by the cleaning mode switching switch.

[0155] The cleaning mode switching switch is configured to be triggered and generate a mode switching signal.

[0156] The control unit is used to obtain a mode switching signal and determine the working mode to be switched according to the mode switching signal, and is used to obtain the current working mode of the cleaning device 10 to control at least one of the first cleaning member 112 and the second cleaning member 122 to complete a switch between the lifting position and the working position according to the current working mode, thereby switching to the working mode to be switched.

[0157] The control unit is also used to receive a mode switching signal, and determine whether to switch the cleaning member from the working position to the lifted position based on the mode switching signal, and generate a second drive instruction when it is determined that the cleaning member needs to be switched from the working position to the lifted position, and control the drive member 1021 to drive the cleaning member from the working position to the lifted position along a second direction based on the second drive instruction.

[0159] In some embodiments, the device body 13 is provided with a detection element 132 and a control unit. The detection element 132 is used to detect whether the cleaning member is in the lifting position, and generates a lifting position signal when the cleaning member is detected to be in the lifting position, and sends the lifting position signal to the control unit; the control unit is used to receive the mode switching signal and the lifting position signal, and judge whether to switch the cleaning member from the lifting position to the working position according to the mode switching signal and the lifting position signal, and when it is judged that the cleaning member needs to be switched from the lifting position to the working position, the control unit generates a first driving instruction and increases the current power of the driving member 1021 according to the first driving instruction and controls the driving member 1021 to drive the cleaning member out of the lifting position along the first direction.

[0160] The detection element 132 is also used to detect whether the cleaning member is in the lifted position, and generates a lift-off signal when it detects that the cleaning member has left the lifted position, and sends the lift-off signal to the control unit; the control unit is also used to receive the lift-off signal and stop driving the driving member 1021 according to the lift-off signal, allowing the cleaning member to descend to the working position using gravity.

For example, the magnetic member can be set on the above-mentioned lifting frame 1027. The detection element 132 is a Hall element, and the detection element 132 can be set on the device body 13.

[0162] When the lifting assembly 102 and the cleaning member therein switch from the working position to the lifting position and approach the detection element 132, the detection element 132 outputs a lifting position signal by sensing the magnetic field of the magnetic member. In addition, when the lifting assembly 102 and the cleaning member therein switch from the lifting position to the working position and move away from the detection element 132, the detection element 132 outputs a lifting separation signal by sensing the magnetic field of the magnetic member.

[0163] In other embodiments, the detection element 132 is a pressure sensing element, which is disposed on the device body 13 and is located directly above the lifting assembly 102. When the lifting assembly 102 and the cleaning member therein switch from the working position to the lifting position and press against the detection element 132, the detection element 132 senses whether there is a pressing force and outputs a lifting-in-place signal when it is determined that there is a pressing force. When the cleaning member switches from the lifting position to the working position and moves away from the detection element 132, the detection element 132 senses whether there is a pressing force and outputs a lifting-out signal when it is determined that there is no pressing force.

The cleaning device 10 not only has the first working mode, the second working mode, the third working mode and the fourth working mode, but also can switch between any working modes. When the cleaning device 10 tends to develop in the direction of comprehensive functions such as sweeping, mopping and washing, it can meet the switching of multiple working modes of the multiple cleaning members possessed by the cleaning device 10.
