Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0034] The present application provides a cleaning device and a lifting device, which are described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of the present application. In the following embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments.

[0035] See also Figure 1 and Figure 2 , Figure 1 is a schematic structural diagram of an embodiment of the cleaning device of the present application, Figure 2 yes Figure 1 A schematic cross-sectional view of the cleaning device shown.

[0036] In one embodiment, the cleaning device may be a cleaning robot with cleaning functions such as floor washing, floor mopping, and floor scrubbing. The cleaning device can automatically move on the surface to be cleaned to clean and remove dust from the surface to be cleaned, and the cleaning device of this embodiment can also scrub the surface to be cleaned. The surface to be cleaned may be the ground, or the surface of an object to be cleaned.

[0037] The cleaning device includes a device body. The device body is the main part of the cleaning device, which is used to carry and protect the other parts of the cleaning device. Optionally, the device body can be provided with a mechanism for driving the cleaning device to move, such as a driving wheel, a crawler, etc. In addition, the device body can also be provided with a wiping member such as a roller brush, and in addition, the device body can also have a dust collection function.

[0038] The cleaning device also includes a cleaning component 20, which is used to clean the surface to be cleaned. Specifically, when the cleaning device is applied to a cleaning robot, the cleaning component 20 can be rotatable, that is, the cleaning component 20 rotates around its own central axis to scrub the surface to be cleaned. Optionally, the cleaning component 20 may include a rotatable cleaning member (not shown), for example, the cleaning component 20 includes a cleaning disk 21 and a cleaning member disposed on the cleaning disk 21, and the cleaning member may be a wiping member such as a rag, for example Figure 2 shown.

[0039] The cleaning device further includes a lifting assembly 30. The lifting assembly 30 is disposed on the device body, and the lifting assembly 30 is in transmission connection with the cleaning assembly 20. The lifting assembly 30 is used to drive the cleaning assembly 20 to rise and fall. When the cleaning assembly 20 is needed to clean the surface to be cleaned, the lifting assembly 30 drives the cleaning assembly 20 to fall, so that the cleaning assembly 20 is close to the surface to be cleaned to clean the surface to be cleaned. When the cleaning assembly 20 is not needed to clean the surface to be cleaned, the lifting assembly 30 drives the cleaning assembly 20 to rise, so that the cleaning assembly 20 is away from the surface to be cleaned, which is conducive to improving the obstacle avoidance ability of the cleaning device.

[0040] The cleaning device further comprises a driving assembly 10. The driving assembly 10 is in driving connection with the cleaning assembly 20. The driving assembly 10 is the core driving component of the cleaning device, and the driving assembly 10 is used to drive the cleaning assembly 20 to rotate to clean the surface to be cleaned and also to drive the cleaning assembly 20 to be lifted and lowered through the lifting assembly 30.

[0041] Specifically, the driving assembly 10 includes a housing 11, a driving member 12 and a power output shaft 13. The housing 11 is connected to the main body of the device. The driving member 12 is arranged in the housing 11, and the driving member 12 is also connected to the power output shaft 13 in a transmission manner. The driving member 12 can be a power element such as a motor. The housing 11 includes a housing cover 111 and a housing seat 112. The housing cover 111 is covered on the housing seat 112, so that the housing cover 111 and the housing seat 112 cooperate to enclose a space for arranging the driving member 12 and the power output shaft 13. The driving assembly 10 uses the output shaft of the driving member 12 as the power input end, and transmits the power output of the driving member 12 to the power output shaft 13 through a multi-stage gear pair, so that the power output shaft 13 drives the cleaning assembly 20 to rotate and drives the cleaning assembly 20 to rise and fall. The power output shaft 13 has a central axis (such as Figure 2 The extension direction of the central axis is the axial direction of the power output shaft 13. The orthographic projection of the output shaft on the driving member 12 on the central axis O overlaps with the orthographic projection of the power output shaft 13 on the central axis O, making the structure of the driving assembly 10 more compact and reducing the size of the driving assembly 10 in the extension direction of the central axis O, that is, reducing the longitudinal space occupied by the driving assembly 10.

[0042] It should be noted that the axial direction of the power output shaft 13 is the lifting direction of the cleaning assembly 20 (eg Figure 2Indicated by the arrow X in the middle, the same below). The lifting direction is perpendicular to the surface to be cleaned. The cleaning component 20 rises or falls along the lifting direction, that is, the cleaning component 20 moves toward or away from the surface to be cleaned along the lifting direction. The movement of the cleaning component 20 in the direction away from the surface to be cleaned means that the cleaning component 20 rises, and the movement of the cleaning component 20 toward the surface to be cleaned means that the cleaning component 20 falls. The rising or falling of the cleaning component 20 in the embodiment of the present application is with respect to the surface to be cleaned. When the surface to be cleaned is the ground, the lifting direction is the vertical direction perpendicular to the ground, and the cleaning component 20 rises or falls relative to the surface to be cleaned along the lifting direction. When the surface to be cleaned is the surface to be cleaned of an object, or the surface to be cleaned is inclined or vertically arranged relative to the horizontal plane, the lifting direction is the direction perpendicular to the surface to be cleaned, and the cleaning component 20 rises or falls relative to the surface to be cleaned along the lifting direction.

[0043] Please also read Figure 3 , Figure 3 yes Figure 1 The exploded structural diagram of the cleaning device is shown. The lifting assembly 30 of the embodiment of the present application is described below.

[0044] In one embodiment, the lifting assembly 30 includes a lifting member 31, a transmission member 32, a guide member 33 and a resistance member 34. The lifting member 31 is connected to the power output shaft 13 through the transmission member 32, so that the power output shaft 13 is connected to the cleaning assembly 20 through the lifting member 31. The lifting member 31 can rotate synchronously with the transmission member 32 and the cleaning assembly 20, and the power output shaft 13 drives the cleaning assembly 20 to rotate through the transmission member 32 and the lifting member 31 in turn to clean the surface to be cleaned. The lifting member 31 and the transmission member 32 can also move relative to each other, specifically, the lifting member 31 moves relative to the transmission member 32 along the axial direction of the power output shaft 13, so that the lifting member 31 can drive the cleaning assembly 20 to move relative to the transmission member 32 along the axial direction of the power output shaft 13, that is, drive the cleaning assembly 20 to lift. The guide member 33 is rotatably connected to the box 11 through the resistance member 34, and the guide member 33 can rotate around the power output shaft 13 relative to the box 11. The guide member 33 is also connected to the lifting member 31. The guide member 33 is used to guide the lifting member 31 to move relative to the transmission member 32 along the axial direction of the power output shaft 13 under the drive of the driving member 12, so as to guide the cleaning assembly 20 to be lifted and lowered. During the axial movement of the lifting member 31 relative to the transmission member 32 along the power output shaft 13, the resistance member 34 prevents the guide member 33 from rotating relative to the box body 11, and the guide member 33 preferably remains stationary. During the cleaning assembly 20 cleaning the surface to be cleaned, the driving member 12 drives the guide member 33 to rotate synchronously through the lifting member 31.

[0045] In the above manner, in this embodiment, under the drive of the driving member 12, the guide member 33 guides the lifting member 31 to move axially relative to the transmission member 32 along the power output shaft 13, so that the lifting member 31 drives the cleaning component 20 to move axially relative to the transmission member 32 along the power output shaft 13, that is, the lifting design of the cleaning component 20 is realized. In addition, during the axial movement of the lifting member 31 relative to the transmission member 32 along the power output shaft 13, the resistance member 34 prevents the guide member 33 from rotating relative to the box 11, so that the guide member 33 can reliably guide the movement of the lifting member 31. In the process of the cleaning component 20 cleaning the surface to be cleaned, the driving member 12 drives the guide member 33 to rotate synchronously through the lifting member 31, so that the guide member 33 adapts to the cleaning component 20 to clean the surface to be cleaned by rotation.

[0046] For details, please refer to Figure 4 , one of the lifting member 31 and the guide member 33 is provided with a spiral track 35, and the spiral track 35 extends spirally around the power output shaft 13. The lifting assembly 30 also includes a guide moving member 37. The guide moving member 37 is provided on the other of the lifting member 31 and the guide member 33, and the guide moving member 37 is movably provided on the spiral track 35. In this embodiment, the lifting member 31 is guided to move relative to the transmission member 32 along the axial direction of the power output shaft 13 by moving the guide moving member 37 along the spiral track 35. Specifically, the transmission member 32 may be fixed in the axial direction of the power output shaft 13, and the lifting member 31 moves along the axial direction of the power output shaft 13.

[0047] Figure 3 and Figure 4 Demonstrated exemplary guide member 33 is provided with spiral track 35, and lifting member 31 is provided with guide moving member 37.Guide moving member 37 can be roller etc., and guide moving member 37 is installed on lifting member 31 by fixed shaft.Spiral track 35 specifically can be chute structure etc.Guide moving member 37 protrudes from the outer side wall of lifting member 31, makes guide moving member 37 can be embedded in spiral track 35, and guide moving member 37 can roll along spiral track 35, to guide lifting member 31 relative transmission member 32 along the axial movement of power output shaft 13.Guide moving member 37 is rolling friction fit with spiral track 35, helps to reduce the friction resistance between guide moving member 37 and spiral track 35.Certainly, in other embodiments of the present application, guide moving member 37 also can adopt non-rollable design, and guide moving member 37 can slide along spiral track 35 instead, is not limited at this.

[0048] The resistance member 34 is a resistance bearing. The resistance member 34 has an inner ring and an outer ring which are nested with each other. One of the housing 11 and the guide member 33 is connected to the inner ring, and the other is connected to the outer ring. The central axis of the resistance member 34 coincides with the central axis of the power output shaft 13. For example, the guide member 33 is generally a hollow cylindrical structure, and the guide member 33 is arranged around the outer periphery of the lifting member 31, so that the structure of the lifting assembly 30 is relatively compact, which is conducive to the miniaturization design of the lifting assembly 30. The spiral track 35 is located on the inner side of the guide member 33, and the guide moving member 37 is located on the outer side of the lifting member 31. The guide member 33 is connected to the outer ring of the resistance member 34, and the housing 11 is connected to the inner ring of the resistance member 34. The resistance member 34 can provide bidirectional resistance, that is, when the guide member 33 rotates bidirectionally relative to the housing 11, the resistance member 34 can apply resistance between the housing 11 and the guide member 33 to hinder the relative rotation between the housing 11 and the guide member 33. The fact that the resistance member 34 hinders the relative rotation between the box body 11 and the guide member 33 does not mean that the box body 11 and the guide member 33 cannot rotate relative to each other. In fact, the direction of the resistance provided by the resistance member 34 is opposite to the direction of the driving force that drives the guide member 33 to rotate relative to the box body 11. When the driving force is large enough, the driving force can overcome the resistance provided by the resistance member 34 and cause the guide member 33 to rotate relative to the box body 11.

[0049] Of course, in other embodiments of the present application, the resistance member 34 may also be a roller, etc. The resistance member 34 is fixed to the box body 11, and the resistance member 34 abuts against the guide member 33 with interference, so that the resistance member 34 applies resistance to the guide member 33 to hinder the relative rotation between the box body 11 and the guide member 33. Alternatively, the resistance member 34 may also be an elastic element such as a spring or a spring sheet, and the resistance member 34 elastically abuts against the guide member 33, so that the resistance member 34 can provide resistance in the direction in which the guide member 33 rotates relative to the box body 11.

[0050] Furthermore, the drive assembly 10 also includes a rotating bearing 14. The power output shaft 13 is arranged in the housing 11 through the rotating bearing 14. The rotating bearing 14 and the resistance member 34 are nested with each other, and specifically, the resistance member 34 is arranged around the outer periphery of the rotating bearing 14. The drive assembly 10 also includes a baffle 15, which is fixed to the housing 11. The rotating bearing 14 and the resistance member 34 are clamped between the baffle 15 and the housing 11. The baffle 15 is located on the inner side of the neck of the guide member 33, that is, the baffle 15 is located in the internal space of the guide member 33 and close to the housing 11. The baffle 15 is annular. The baffle 15 can be locked to the housing 11 by fasteners such as screws, and the baffle 15 simultaneously fixes the rotating bearing 14 and the resistance member 34 to the housing 11.

[0051] In one embodiment, the lifting assembly 30 further includes a limiting portion 36. The limiting portion 36 is disposed on the spiral track 35, and specifically can be disposed at the end of the spiral track 35 close to the surface to be cleaned. During the descent of the cleaning assembly 20, the guide moving member 37 moves along the spiral track 35 and toward the surface to be cleaned, driving the lifting member 31 to move toward the surface to be cleaned. During the axial movement of the lifting member 31 relative to the transmission member 32 along the power output shaft 13, the force applied by the guide moving member 37 to the guide member 33, the resistance applied by the resistance member 34 to the guide member 33, and the force applied by the power output shaft 13 to the guide moving member 37 increase in sequence. Specifically, the resistance force applied by the resistance member 34 to the guide member 33 is greater than the force applied by the guide movable member 37 to the guide member 33, and the resistance force applied by the resistance member 34 to the guide member 33 is much smaller than the force applied by the power output shaft 13 to the guide movable member 37, so that the guide member 33 remains stationary during the axial movement of the lifting member 31 relative to the transmission member 32 along the power output shaft 13 (including the movement of the lifting member 31 toward the surface to be cleaned and the movement of the lifting member 31 away from the surface to be cleaned), so that the guide member 33 can reliably guide the movement of the lifting member 31. When the guide movable member 37 moves to the abutment limit portion 36, the lifting member 31 drives the guide member 33 to rotate synchronously, specifically, the lifting member 31 supports the limit portion 36 through the guide movable member 37 to drive the guide member 33 to rotate synchronously, so that the guide member 33 can adapt to the cleaning assembly 20 to clean the surface to be cleaned by rotating.

[0052] The end of the spiral track 35 away from the surface to be cleaned has a limiting surface 353. When the guide moving member 37 moves to abut the limiting surface 353, the limiting surface 353 limits the guide moving member 37 to continue to move away from the surface to be cleaned along the spiral track 35, thus limiting the lifting member 31 from continuing to move away from the surface to be cleaned.

[0053] It should be noted that, in this embodiment, when the driving member 12 drives the power output shaft 13 to rotate in the first rotation direction, the power output shaft 13 drives the transmission member 32 to rotate synchronously with the lifting member 31, so as to drive the guide moving member 37 to move along the spiral track 35 and toward the surface to be cleaned through the lifting member 31, and then guide the lifting member 31 to drive the cleaning component 20 to move toward the surface to be cleaned. In this process, due to the transmission cooperation between the cleaning component 20 and the lifting member 31, the cleaning component 20 rotates adaptively. When the guided moving member 37 moves to the contact limit portion 36, the cleaning component 20 drops to the working position, and the power output shaft 13 continues to drive the cleaning component 20 to rotate to clean the surface to be cleaned. At the same time, the power output shaft 13 also drives the guide member 33 to rotate synchronously. When the driving member 12 drives the power output shaft 13 to rotate in the second rotation direction, the power output shaft 13 also drives the transmission member 32 to rotate synchronously with the lifting member 31, so as to drive the guide moving member 37 to move along the spiral track 35 and in a direction away from the surface to be cleaned through the lifting member 31, thereby guiding the lifting member 31 to drive the cleaning assembly 20 to move in a direction away from the surface to be cleaned, until the guide moving member 37 moves to the contact limit surface 353. The first rotation direction is opposite to the second rotation direction, which means that in this embodiment, the driving member 12 drives the power output shaft 13 to rotate forward and reversely, so as to control the cleaning assembly 20 to rise and fall.

[0054] Furthermore, the limiting portion 36 is detachably connected to the spiral track 35, and the limiting portion 36 is configured to be connected to the spiral track 35 after the guide movable member 37 is installed in the spiral track 35. Considering that the limiting surface 353 and the guide member 33 are an integral structure, the limiting portion 36 and the guide member 33 are detachably connected in this embodiment, and the guide movable member 37 is installed in the spiral track 35 from the end of the spiral track 35 close to the surface to be cleaned, and then the limiting portion 36 is connected to the guide member 33 to prevent the guide movable member 37 from falling out of the spiral track 35, so that assembly is convenient.

[0055] For example, the spiral track 35 includes a first spiral track 351 and a second spiral track 352. The first spiral track 351 and the second spiral track 352 are spaced apart along the circumference of the power output shaft 13, and the spiral direction of the first spiral track 351 is the same as the spiral direction of the second spiral track 352. The first spiral track 351 and the second spiral track 352 are opened on the inner wall of the guide member 33. The limiting portion 36 includes a first limiting portion 361 and a second limiting portion 362, the first limiting portion 361 is arranged at the end of the first spiral track 351 close to the surface to be cleaned, and the second limiting portion 362 is arranged at the end of the second spiral track 352 close to the surface to be cleaned. In addition, the end of the first spiral track 351 away from the surface to be cleaned and the end of the second spiral track 352 away from the surface to be cleaned are respectively provided with corresponding limiting surfaces 353. Please refer to Figure 5The guide moving member 37 includes a first guide moving member 371 and a second guide moving member 372, the first guide moving member 371 and the second guide moving member 372 are spaced apart along the circumference of the power output shaft 13, the first guide moving member 371 is movably arranged on the first spiral track 351, and the second guide moving member 372 is movably arranged on the second spiral track 352. When the first guide moving member 371 moves to abut the first limit portion 361 and the second guide moving member 372 moves to abut the second limit portion 362, the lifting member 31 drives the guide member 33 to rotate synchronously. The present embodiment is conducive to reliably and stably guiding the lifting member 31 to move relative to the transmission member 32 along the axial direction of the power output shaft 13 by arranging at least two groups of spiral tracks 35 and guide moving members 37.

[0056] Of course, in other embodiments of the present application, only one set of spiral tracks 35 and guide moving parts 37 may be provided, which can also realize the axial movement of the guiding lifting member 31 relative to the transmission member 32 along the power output shaft 13 and simplify the structure of the lifting assembly 30.

[0057] Please also read Figure 6 and Figure 7 , Figure 6 yes Figure 5 The structural diagram of the lifting member from another perspective is shown. Figure 7 It is a structural schematic diagram of an embodiment of a transmission member of the present application.

[0058] In one embodiment, one of the lifting member 31 and the transmission member 32 is provided with a stop track 38, and the stop track 38 extends along the axial direction of the power output shaft 13. The lifting assembly 30 also includes a stop moving member 39. The stop moving member 39 is provided at the other of the lifting member 31 and the transmission member 32, and the stop moving member 39 is movably provided at the stop track 38 to allow the lifting member 31 to move relative to the transmission member 32 along the axial direction of the power output shaft 13 and limit the relative rotation between the lifting member 31 and the transmission member 32. The stop moving member 39 can move along the stop track 38, so that the lifting member 31 and the transmission member 32 can move relative to each other along the axial direction of the power output shaft 13, and the stop track 38 can cooperate with the stop moving member 39 to limit the relative rotation between the lifting member 31 and the transmission member 32.

[0059] Alternatively, the non-rotating moving member 39 can be a roller etc., and the non-rotating moving member 39 is installed on the lifting member 31 and / or the transmission member 32 by a fixed shaft. The non-rotating track 38 can specifically be a chute structure etc., and the non-rotating moving member 39 is embedded in the non-rotating track 38, and the non-rotating moving member 39 can roll along the non-rotating track 38, so that the lifting member 31 and the transmission member 32 can move relative to each other along the axial direction of the power output shaft 13. Between the non-rotating moving member 39 and the non-rotating track 38, there is a rolling friction fit, which helps to reduce the friction resistance between the non-rotating moving member 39 and the non-rotating track 38. Of course, in other embodiments of the present application, the non-rotating moving member 39 can also adopt a non-rollable design, and the non-rotating moving member 39 can slide along the non-rotating track 38 instead, which is not limited here.

The first guide moving member 371 and the second guide moving member 372 are located on the outer side wall of the guide part 313, and the first guide moving member 371 and the second guide moving member 372 are arranged opposite to each other. The interior of the first transmission part 311 has a transmission cavity 312, and a part of the cleaning component 20 is embedded in the transmission cavity 312 to be transmission-connected with the first transmission part 311. Please refer to Figure 8The cleaning disc 21 of the cleaning assembly 20 has a transmission column 22 on the side facing away from the cleaning member. The transmission column 22 is a prism. The inner side wall of the transmission cavity 312 is a polyhedral structure corresponding to the transmission column 22, such as Figure 6 As shown. The transmission column 22 is embedded in the transmission cavity 312, and the outer wall of the transmission column 22 and the inner wall of the transmission cavity 312 cooperate with each other to stop rotation, so that the lifting member 31 is connected to the cleaning component 20 in a transmission manner, that is, the lifting member 31 can drive the cleaning component 20 to rotate. The guide part 313 is also connected to the guide member 33. The inner wall of the guide part 313 and the outer wall of the first transmission part 311 are spaced apart from each other to form a accommodating cavity 315. The second anti-rotation moving member 392 is located on the inner wall of the guide part 313. The number of the second anti-rotation moving member 392 can be one or more, Figure 5 The example shows that there are two second anti-rotation moving members 392, and the two second anti-rotation moving members 392 are evenly spaced along the circumference of the guide portion 313.

[0062] The transmission member 32 includes a second connecting portion 321 and a second transmission portion 322. The second connecting portion 321 is in transmission connection with the power output shaft 13. The second connecting portion 321 can be locked to the power output shaft 13 by fasteners such as screws. The second transmission portion 322 is arranged around the outer periphery of the second connecting portion 321. The transmission member 32 generally presents a hollow sleeve structure. The second transmission portion 322 is embedded in the accommodating cavity 315, so that the structure of the lifting member 31 and the transmission member 32 is relatively compact, which is conducive to the miniaturization design of the lifting assembly 30.

[0065] In one embodiment, the lifting device includes a driving assembly 10. The driving assembly 10 includes a housing 11, a driving member 12 and a power output shaft 13, the driving member 12 is arranged in the housing 11, and the driving member 12 is also connected to the power output shaft 13, so as to drive the cleaning assembly 20 to rotate through the power output shaft 13 to clean the surface to be cleaned. The lifting device also includes a lifting assembly 30. The lifting assembly 30 includes a lifting member 31, a transmission member 32, a guide member 33 and a resistance member 34. The lifting member 31 is connected to the power output shaft 13 through the transmission member 32, so that the power output shaft 13 is connected to the cleaning assembly 20 through the lifting member 31, and the lifting member 31 can also drive the cleaning assembly 20 to move axially relative to the transmission member 32 along the power output shaft 13. The guide member 33 is rotatably connected to the housing 11 through the resistance member 34, and the guide member 33 is also connected to the lifting member 31, and the guide member 33 is used to guide the lifting member 31 to move axially relative to the transmission member 32 along the power output shaft 13 under the drive of the driving member 12. During the axial movement of the lifting member 31 relative to the transmission member 32 along the power output shaft 13, the resistance member 34 hinders the guide member 33 from rotating relative to the box body 11. During the cleaning assembly 20 cleaning the surface to be cleaned, the driving member 12 drives the guide member 33 to rotate synchronously through the lifting member 31.

[0066] It should be noted that the driving assembly 10 and the lifting assembly 30 of this embodiment have been described in detail in the above embodiments and will not be repeated here.

[0067] The technical solution provided in the embodiments of the present application is described below in conjunction with specific application scenarios.

[0068] Application scenario 1:

[0069] The cleaning device is a cleaning robot. The cleaning assembly 20 on the cleaning device includes a rotatable rag. The cleaning device also includes a lifting assembly 30, which is used to drive the cleaning assembly 20 to descend when the cleaning assembly 20 is needed to clean the floor, and to drive the cleaning assembly 20 to rise when the cleaning assembly 20 is not needed to clean the floor. The cleaning device also includes a driving assembly 10, which is used to drive the cleaning assembly 20 to rotate to clean the floor and is also used to drive the cleaning assembly 20 to rise and fall through the lifting assembly 30.

[0070] The power output by the driving member 12 of the driving assembly 10 is transmitted to the power output shaft 13 through a multi-stage gear pair, so that the power output shaft 13 can rotate forward and backward around its own central axis. The transmission member 32 of the lifting assembly 30 is fixedly connected to the power output shaft 13, so that the transmission member 32 can also rotate forward and backward around the central axis of the power output shaft 13. The lifting member 31 and the transmission member 32 can rotate together, and the lifting member 31 and the transmission member 32 can also perform relative linear motion along the axial direction of the power output shaft 13. The first spiral track 351 and the second spiral track 352 on the guide member 33 are provided with upper and lower limit points. The upper limit points of the first spiral track 351 and the second spiral track 352 are the corresponding limit surfaces 353, and the lower limit points of the first spiral track 351 and the second spiral track 352 are the first limit portion 361 and the second limit portion 362. Therefore, when the first guide movable member 371 and the second guide movable member 372 have not moved to the first limit portion 361 and the second limit portion 362, the guide member 33 is stationary, and the lifting member 31 makes a spiral motion relative to the guide member 33. At this time, the lifting member 31 drives the cleaning component 20 to descend; when the first guide movable member 371 and the second guide movable member 372 move to the first limit portion 361 and the second limit portion 362, the lifting member 31 and the guide member 33 make a rotational motion around the central axis of the power output shaft 13, and at the same time, the lifting member 31 drives the cleaning component 20 to make a rotational motion to clean the floor.

[0071] The working logic of the cleaning device is as follows: when the cleaning component 20 is needed to clean the ground, the driving member 12 drives the power output shaft 13 to rotate in the first rotation direction, driving the cleaning component 20 to move spirally downward, and after the first guide moving member 371 and the second guide moving member 372 move to the first limit portion 361 and the second limit portion 362, the cleaning component 20 contacts the ground, and the driving member 12 drives the cleaning component 20 to rotate around the central axis of the power output shaft 13 through the power output shaft 13 to clean the ground. When the cleaning component 20 needs to be folded to avoid obstacles, the driving member 12 drives the power output shaft 13 to rotate in the second rotation direction, driving the cleaning component 20 to move spirally upward, and stops after the first guide moving member 371 and the second guide moving member 372 move to the corresponding limit surface 353.

[0072] Application scenario 2:

[0073] The lifting device includes a lifting assembly 30, which is used to drive the cleaning assembly 20 to descend when the cleaning assembly 20 is needed to clean the ground, and to drive the cleaning assembly 20 to rise when the cleaning assembly 20 is not needed to clean the ground. The lifting device also includes a driving assembly 10, which is used to drive the cleaning assembly 20 to rotate to clean the ground and is also used to drive the cleaning assembly 20 to rise and fall through the lifting assembly 30.

[0074] The power output by the driving member 12 of the driving assembly 10 is transmitted to the power output shaft 13 through a multi-stage gear pair, so that the power output shaft 13 can rotate forward and backward around its own central axis. The transmission member 32 of the lifting assembly 30 is fixedly connected to the power output shaft 13, so that the transmission member 32 can also rotate forward and backward around the central axis of the power output shaft 13. The lifting member 31 and the transmission member 32 can rotate together, and the lifting member 31 and the transmission member 32 can also perform relative linear motion along the axial direction of the power output shaft 13. The first spiral track 351 and the second spiral track 352 on the guide member 33 are provided with upper and lower limit points. The upper limit points of the first spiral track 351 and the second spiral track 352 are the corresponding limit surfaces 353, and the lower limit points of the first spiral track 351 and the second spiral track 352 are the first limit portion 361 and the second limit portion 362. Therefore, when the first guide movable member 371 and the second guide movable member 372 have not moved to the first limit portion 361 and the second limit portion 362, the guide member 33 is stationary, and the lifting member 31 makes a spiral motion relative to the guide member 33. At this time, the lifting member 31 drives the cleaning component 20 to descend; when the first guide movable member 371 and the second guide movable member 372 move to the first limit portion 361 and the second limit portion 362, the lifting member 31 and the guide member 33 make a rotational motion around the central axis of the power output shaft 13, and at the same time, the lifting member 31 drives the cleaning component 20 to make a rotational motion to clean the floor.

[0075] The working logic of the lifting device is as follows: when the cleaning component 20 is needed to clean the ground, the driving member 12 drives the power output shaft 13 to rotate in the first rotation direction, driving the cleaning component 20 to move spirally downward, and after the first guide moving member 371 and the second guide moving member 372 move to the first limit portion 361 and the second limit portion 362, the cleaning component 20 contacts the ground, and the driving member 12 drives the cleaning component 20 to rotate around the central axis of the power output shaft 13 through the power output shaft 13 to clean the ground. When the cleaning component 20 needs to be folded to avoid obstacles, the driving member 12 drives the power output shaft 13 to rotate in the second rotation direction, driving the cleaning component 20 to move spirally upward, and stops after the first guide moving member 371 and the second guide moving member 372 move to the corresponding limit surface 353.

[0076] The cleaning device and lifting device provided by the present application are introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea; at the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation method and application scope.
