[0002] A cleaning robot is a smart home appliance that can automatically clean the floor in a room with a certain degree of artificial intelligence.

DETAILED DESCRIPTION

[0048] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0049] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

In all examples shown and discussed here, any specific values ​​should be interpreted as being merely exemplary, not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0051] As mentioned in the background technology, existing cleaning robots often need to switch between the sweeping and mopping cleaning modules simultaneously when switching working modes. Two different drive mechanisms are often set up inside the cleaning robot to control the lifting and lowering of the two cleaning modules respectively, thereby achieving the switching of the cleaning working modes. However, this will result in a large number of internal parts of the cleaning robot and increase the cost, which is not conducive to achieving a compact and miniaturized internal structure of the machine. To this end, the inventors of this application have designed a new cleaning device, which can solve the problem that cleaning robots in the prior art need to use multiple drive mechanisms to control different cleaning modules, resulting in a large number of internal parts and high costs. The cleaning device of this application will be described in detail below with reference to the accompanying drawings.

[0052] See also Figures 1 to 9 As shown, according to an embodiment of the present application, a cleaning device is provided, which includes a body 10 and a driving mechanism 20.

[0053] Specifically, a first cleaning member 11 and a second cleaning member 12 are provided at the bottom of the body 10; a driving mechanism 20 is provided on the body 10, and the driving mechanism 20 includes a driving component 21, a rotating member 22 and a connecting component 23, the connecting component 23 is connected to the rotating member 22, the first cleaning member 11 and the second cleaning member 12, and the driving component 21 is connected to the rotating member 22 to drive the rotating member 22 to rotate in a first direction or in a second direction opposite to the first direction; wherein the first cleaning member 11 and the second cleaning member 12 both have a lifting state and a lowering state, and ... When the cleaning device is in the initial position, both the member 11 and the second cleaning member 12 are in a lowered state; when the driving component 21 drives the rotating member 22 to rotate in the first direction, the connecting component 23 drives the first cleaning member 11 to switch from the lowered state to the raised state under the rotation of the rotating member 22, and makes the second cleaning member 12 in a lowered state; when the driving component 21 drives the rotating member 22 to rotate in the second direction, the connecting component 23 drives the second cleaning member 12 to switch from the lowered state to the raised state under the action of the rotating member 22, and makes the first cleaning member 11 in a lowered state.

[0054] It should be noted that the “first direction” in this application refers to the Figure 5 The direction indicated by the letter X in the figure is the direction indicated by the letter X in the figure. The second direction is the direction indicated by the letter X in the figure. Figure 5 The direction is indicated by the letter Y. For example, the first cleaning member 11 in this embodiment includes a roller, and the second cleaning member 12 includes a middle sweeper.

[0055] In this embodiment, when at least one of the first cleaning member 11 and the second cleaning member 12 is in a lowered state, the cleaning device can perform cleaning operations using the first cleaning member 11 and the second cleaning member 12. Because the connecting assembly 23 in this embodiment is connected to the rotating member 22, the first cleaning member 11, and the second cleaning member 12, when the cleaning device in this embodiment is in operation, the driving assembly 21 disposed on the body 10 can drive the rotating member 22 to rotate in a first direction or a second direction. As a result, the connecting assembly 23, under the rotation of the rotating member 22, drives the first cleaning member 11 and the second cleaning member 12 to alternately be raised and lowered, thereby achieving switching between different cleaning modules. In other words, in this embodiment, a single driving mechanism 20 can simultaneously control the raising and lowering of the first cleaning member 11 and the second cleaning member 12, eliminating the need for multiple additional driving mechanisms 20 to switch between different cleaning modules. This reduces the space occupancy within the body 10, effectively improving space utilization within the body 10 and reducing manufacturing costs.

[0056] Furthermore, in this embodiment, both the first cleaning member 11 and the second cleaning member 12 are provided with elastic members (not shown in the drawings). When the cleaning device is in the initial position, the elastic members are in a natural state. It should be noted that the "elastic members in a natural state" in this embodiment refers to a state in which the elastic members are neither stretched nor compressed.

[0057] Specifically, the setting of the elastic member can provide a buffering effect for the first cleaning member 11 and the second cleaning member 12, reducing the impact force on the first cleaning member 11 and the second cleaning member 12 during the lifting or lowering process. When the connecting component 23 drives the first cleaning member 11 to switch from the lowered state to the raised state, the first cleaning member 11 will overcome the elastic force of the elastic member and lift; when the connecting component 23 drives the first cleaning member 11 to switch from the raised state to the lowered state, the first cleaning member 11 will release the force resisting the elastic member and descend; similarly, when the connecting component 23 drives the second cleaning member 12 to switch from the lowered state to the raised state, the second cleaning member 12 will overcome the elastic force of the elastic member and lift; when the connecting component 23 drives the second cleaning member 12 to switch from the raised state to the lowered state, the second cleaning member 12 will release the force resisting the elastic member and descend.

[0058] Illustratively, the elastic member in this embodiment includes a structure with elastic effect, such as a spring and an elastic pad.

[0059] Further, see Figure 3 As shown, the connecting component 23 in this embodiment includes a first connecting rope 231 and a second connecting rope 232. The opposite ends of the first connecting rope 231 are respectively connected to the rotating member 22 and the first cleaning member 11, and the opposite ends of the second connecting rope 232 are respectively connected to the rotating member 22 and the second cleaning member 12.

[0060] Specifically, in this embodiment, the rotational power of the rotating member 22 can be accurately transmitted to the first cleaning member 11 and the second cleaning member 12 through the first connecting rope 231 and the second connecting rope 232. When the cleaning device is in the initial position, the first connecting rope 231 and the second connecting rope 232 are both in a released state, so that the first cleaning member 11 and the second cleaning member 12 are both in a lowered state; when the driving assembly 21 drives the rotating member 22 to rotate in the first direction, the first connecting rope 231 is wound around the rotating member 22 under the rotation of the rotating member 22, driving the first cleaning member 11 to rise. At this time, the second connecting rope 232 is in a released state, causing the second cleaning member 12 to fall. When the driving assembly 21 drives the rotating member 22 to rotate in the second direction, the second connecting rope 232 is wound around the rotating member 22 under the rotation of the rotating member 22, driving the second cleaning member 12 to rise. At this time, the first connecting rope 231 is in a released state, causing the first cleaning member 11 to fall. In addition, the structures of the first connecting rope 231 and the second connecting rope 232 are relatively simple. Compared with a complex mechanical transmission structure, the connecting ropes are easier to install and maintain, thereby reducing the production cost of the cleaning device.

[0061] Further, see Figure 4 As shown, the rotating member 22 in this embodiment includes a pulley 221, and the outer surface of the pulley 221 is provided with a first annular groove 222 and a second annular groove 223. The first annular groove 222 and the second annular groove 223 are both arranged around the circumferential direction of the pulley 221, and are arranged side by side in sequence along the axial direction of the pulley 221, and at least part of the first connecting rope 231 is wound around the first annular groove 222, and at least part of the second connecting rope 232 is wound around the second annular groove 223.

[0062] Specifically, the arrangement of the first annular groove 222 and the second annular groove 223 provides a clear winding path for the first connecting rope 231 and the second connecting rope 232. This is because the first annular groove 222 and the second annular groove 223 are arranged along the circumferential direction of the spool 221, thereby allowing the first connecting rope 231 and the second connecting rope 232 to be neatly wound around the spool 221, effectively ensuring the stability of the first connecting rope 231 and the second connecting rope 232 during the winding and unwinding process. At the same time, since the first annular groove 222 and the second annular groove 223 in this embodiment are arranged side by side in sequence along the axis of the spool 221, this arrangement can effectively distinguish the first connecting rope 231 and the second connecting rope 232, effectively preventing the two connecting ropes from being entangled or interfering with each other, and to a certain extent ensuring the stability of the operation of the cleaning device. In addition, since at least part of the first connecting rope 231 in this embodiment is wound around the first annular groove 222, and at least part of the second connecting rope 232 is wound around the second annular groove 223, such an arrangement can ensure that the positions of the first connecting rope 231 and the second connecting rope 232 on the rotating member 22 are relatively fixed, thereby ensuring the stability of the connection and making power transmission more reliable.

[0063] Further, see Figure 4 As shown, in this embodiment, a first limiting portion 30 is provided in the first annular groove 222, and the first limiting portion 30 is used to limit the end of the first connecting rope 231 connected to the rotating member 22, and a second limiting portion 40 is provided in the second annular groove 223, and the second limiting portion 40 is used to limit the end of the second connecting rope 232 connected to the rotating member 22.

[0064] Specifically, the first stopper 30 effectively prevents the first connecting rope 231 from disengaging from the first annular groove 222, and the second stopper 40 effectively prevents the second connecting rope 232 from disengaging from the second annular groove 223. When the rotating member 22 rotates at high speed or is subjected to a significant external force, the first and second connecting ropes 231, 232 are susceptible to centrifugal force or displacement. The first and second stopper 30, 40 secure one end of the first connecting rope 231 in the first annular groove 222, and one end of the second connecting rope 232 in the second annular groove 223, respectively, ensuring that the first and second connecting ropes 231, 232 remain in the correct positions during operation. Furthermore, the first stopper 30 helps determine the starting position of the first connecting rope 231 in the first annular groove 222, and the second stopper 40 helps determine the starting position of the second connecting rope 232 in the second annular groove 223, thereby ensuring the normal operation of the drive mechanism 20.

[0065] Further, see Figure 4As shown, in this embodiment, the projection of the first limiting portion 30 and the projection of the second limiting portion 40 are offset along the axis of the spool 221. It should be noted that "offset" in this embodiment means that the projection of the first limiting portion 30 and the projection of the second limiting portion 40 do not overlap along the axis of the spool 221. Alternatively, there may be a gap between the projection of the first limiting portion 30 and the projection of the second limiting portion 40, or the projection of the first limiting portion 30 may be adjacent to the projection of the second limiting portion 40.

[0066] Specifically, since the first limiting portion 30 in this embodiment is used to limit one end of the first connecting rope 231, and the second limiting portion 40 is used to limit one end of the second connecting rope 232, when the projection of the first limiting portion 30 and the projection of the second limiting portion 40 are staggered, the first connecting rope 231 and the second connecting rope 232 can cause the first cleaning member 11 and the second cleaning member 12 to be in different states during the rotation of the pulley 221. That is: when the pulley 221 rotates along the first direction, the first connecting rope 231 can be wound around the pulley 221 to drive the first cleaning member 11 to switch from the lowered state to the raised state, and at the same time, the second connecting rope 232 is released from the pulley 221 to drive the second cleaning member 12 to be in the lowered state; when the pulley 221 rotates along the second direction, the first connecting rope 231 is released from the pulley 221 to drive the first cleaning member 11 to switch from the raised state to the lowered state, and at the same time, the second connecting rope 232 can be wound around the pulley 221 to drive the second cleaning member 12 to switch from the lowered state to the raised state.

[0067] This staggered layout allows the retraction and extension of the first and second connecting cords 231, 232 to complement each other, preventing the simultaneous tightening or loosening of the first and second connecting cords 231, 232 due to overlapping projections of the first and second limiting portions 30, 40. This ensures that the first and second cleaning members 11, 12 can stably perform alternating movements of one rising and one falling, effectively completing the cleaning task. Furthermore, the staggered projections reduce the risk of entanglement between the first and second connecting cords 231, 232, lowering the impact of motion interference on the reliability of the device and extending the service life of the entire cleaning device.

[0068] Further, see Figure 4 As shown, the first limiting portion 30 in this embodiment includes a first limiting section 31, the first limiting section 31 has a first limiting hole 32, one end of the first connecting rope 231 connected to the rotating member 22 is located in the first limiting hole 32, and the maximum cross-sectional area of ​​the first connecting rope 231 (the area of ​​the cross section obtained by cutting the first connecting rope 231 along a direction perpendicular to the length of the first connecting rope 231) is smaller than the minimum cross-sectional area of ​​the first limiting hole 32 (the area of ​​the cross section obtained by cutting the first limiting hole 32 along an extension direction perpendicular to the first limiting hole 32).

[0069] Specifically, the maximum cross-sectional area of ​​the first connecting cord 231 is smaller than the minimum cross-sectional area of ​​the first limiting hole 32. This allows the first connecting cord 231 to be easily inserted into the first limiting hole 32, thereby improving assembly efficiency. Furthermore, because the first connecting cord 231 has ample room to maneuver within the first limiting hole 32, excessive friction between the first connecting cord 231 and the inner wall of the first limiting hole 32 is prevented from being excessively squeezed.

[0070] Further, see Figure 4 As shown, the second limiting portion 40 in this embodiment includes a second limiting section 41, the second limiting section 41 has a second limiting hole 42, the second connecting rope 232 is connected to one end of the rotating member 22 and is located in the second limiting hole 42, and the maximum cross-sectional area of ​​the second connecting rope 232 is smaller than the minimum cross-sectional area of ​​the second limiting hole 42 (the area of ​​the cross section obtained by cutting the second limiting hole 42 along an extension direction perpendicular to the second limiting hole 42).

[0071] Specifically, the maximum cross-sectional area of ​​the second connecting cord 232 is smaller than the minimum cross-sectional area of ​​the second limiting hole 42. This allows the second connecting cord 232 to be easily inserted into the second limiting hole 42, thereby improving assembly efficiency. Furthermore, because the second connecting cord 232 has ample room to maneuver within the second limiting hole 42, excessive friction between the second connecting cord 232 and the inner wall of the second limiting hole 42 is prevented from being excessively squeezed.

[0072] Further, see Figure 4 As shown, in this embodiment, a first avoidance gap 33 is provided on the first limiting section 31, the first avoidance gap 33 is connected to the first limiting hole 32 and extends along the length direction of the first limiting hole 32, and the first connecting rope 231 is connected to one end of the rotating member 22 and has a first stop protrusion 233. The first connecting rope 231 enters the first limiting hole 32 from the first avoidance gap 33 so that the first stop protrusion 233 abuts against the first limiting section 31, and the minimum cross-sectional area of ​​the first stop protrusion 233 is larger than the maximum cross-sectional area of ​​the first limiting hole 32 (the area of ​​the cross section obtained by cutting the first limiting hole 32 along the extension direction perpendicular to the first limiting hole 32).

[0073] Specifically, the presence of the first avoidance notch 33 facilitates the installation of the first connecting rope 231. When inserting the first connecting rope 231 into the first limiting hole 32, the operator can guide the first connecting rope 231 through the first avoidance notch 33, making it easier for the first connecting rope 231 to enter the first limiting hole 32. At the same time, after the first connecting rope 231 is inserted into the first limiting hole 32, the first stop protrusion 233 abuts against the first limiting section 31, thereby ensuring that the first connecting rope 231 is accurately positioned within the first limiting hole 32. This is because the minimum cross-sectional area of ​​the first stop protrusion 233 is larger than the maximum cross-sectional area of ​​the first limiting hole 32. Therefore, the first stop protrusion 233 can be stuck on the first limiting section 31, preventing the first connecting rope 231 from excessively moving or falling out of the first limiting hole 32.

[0074] Further, see Figure 4 As shown, in this embodiment, a second avoidance notch 43 is provided on the second limiting section 41, the second avoidance notch 43 is connected to the second limiting hole 42 and extends along the length direction of the second limiting hole 42, and the second connecting rope 232 is connected to one end of the rotating member 22 and has a second stop protrusion 234. The second connecting rope 232 enters the second limiting hole 42 from the second avoidance notch 43 so that the second stop protrusion 234 abuts against the second limiting section 41, and the minimum cross-sectional area of ​​the second stop protrusion 234 is larger than the maximum cross-sectional area of ​​the second limiting hole 42 (the area of ​​the cross section obtained by cutting the second limiting hole 42 along the extension direction perpendicular to the second limiting hole 42).

[0075] Specifically, the presence of the second avoidance notch 43 facilitates the installation of the second connecting rope 232. When inserting the second connecting rope 232 into the second limiting hole 42, the operator can guide the second connecting rope 232 through the second avoidance notch 43, making it easier for the second connecting rope 232 to enter the second limiting hole 42. At the same time, after the second connecting rope 232 is inserted into the second limiting hole 42, the second stop protrusion 234 abuts against the second limiting section 41, thereby ensuring that the second connecting rope 232 is accurately positioned within the second limiting hole 42. This is because the minimum cross-sectional area of ​​the second stop protrusion 234 is larger than the maximum cross-sectional area of ​​the second limiting hole 42, so the second stop protrusion 234 can be stuck on the second limiting section 41, preventing the second connecting rope 232 from excessively moving or falling out of the second limiting hole 42.

[0076] Further, see Figures 5 to 9As shown, the drive assembly 21 in this embodiment includes a gearbox 211 and a drive motor 215. The gearbox 211 is disposed in the body 10 and includes a housing 212 and a gear set 213. The gear set 213 is disposed within the housing 212. A protective shell 50 is disposed on the housing 212, which encloses a mounting cavity 501. A first escape channel 60 and a second escape channel 70 are disposed on the sidewall of the protective shell 50. The rotating member 22 is rotatably disposed within the mounting cavity 501 and connected to the gear set 213 via a rotating shaft 214. A first connecting rope 231 passes through the first escape channel 60, and a second connecting rope 232 passes through the second escape channel 70. The drive motor 215 is disposed on the housing 212 and is drivingly connected to the gear set 213 to drive the gear set 213 to rotate, thereby driving the rotating member 22 to rotate.

[0077] Specifically, the protective housing 50 not only provides installation space for the rotating member 22 but also isolates it from other components, effectively preventing it from being affected by other components. Furthermore, the coordination between the drive motor 215, the gear set 213, and the rotating member 22 plays a key role in the cleaning device's performance of cleaning operations. The connection between the gear set 213 and the rotating member 22 allows the rotational direction and speed of the rotating member 22 to be precisely controlled under the control of the drive motor 215, effectively ensuring the stability of the rotating member 22's operation. Among them, when the drive motor 215 rotates forward, the drive motor 215 drives the gear group 213 to rotate, thereby driving the rotating member 22 to rotate in the first direction, so that the first connecting rope 231 is wrapped around the rotating member 22, and the second connecting rope 232 is released from the rotating member 22, thereby causing the first cleaning member 11 to switch from the lowered state to the raised state under the action of the first connecting rope 231, and the second cleaning member 12 is in the lowered state under the action of the second connecting rope 232; when the drive motor 215 is reversed, the drive motor 215 drives the gear group 213 to rotate, thereby driving the rotating member 22 to rotate in the second direction, so that the second connecting rope 232 is wrapped around the rotating member 22, and the first connecting rope 231 is released from the rotating member 22, thereby causing the second cleaning member 12 to switch from the lowered state to the raised state under the action of the second connecting rope 232, and the first cleaning member 11 is in the lowered state under the action of the first connecting rope 231. Of course, in other embodiments of the present application, the drive motor 215 can rotate forward to drive the gear set 213 to rotate, thereby driving the rotating member 22 to rotate in the second direction; the drive motor 215 can rotate backward to drive the gear set 213 to rotate, thereby driving the rotating member 22 to rotate in the first direction.

[0078] Further, see Figure 3 as well as Figures 5 to 8As shown, in this embodiment, a first protective sleeve 80 is sleeved on the first connecting rope 231, and a first limiting groove 81 is provided on one of the first protective sleeve 80 and the first avoidance channel 60, and a first limiting protrusion 61 that matches the first limiting groove 81 is provided on the other of the first protective sleeve 80. That is to say, in this embodiment, the first limiting groove 81 can be provided on the first avoidance channel 60 and the first limiting protrusion 61 can be provided on the first protective sleeve 80, or the first limiting groove 81 can be provided on the first avoidance channel 60 and the first limiting protrusion 61 can be provided on the first protective sleeve 80. Figure 6 The first avoidance channel 60 is provided with a first limiting protrusion 61 and an attached Figure 3 FIG. 8 shows a situation where the first protective sleeve 80 is provided with a first limiting groove 81 .

[0079] Specifically, the first connecting rope 231 may come into contact with and rub against various surfaces during use. The provision of the first protective sleeve 80 can provide protection for the first connecting rope 231, reducing wear and tear caused by friction. Furthermore, during the movement of the first connecting rope 231, the first protective sleeve 80 may slide relative to the first avoiding passage 60 due to external forces or its own vibration. The cooperation between the first limiting protrusion 61 and the first limiting groove 81 can effectively secure the first protective sleeve 80 to the first avoiding passage 60, thereby preventing the first protective sleeve 80 from shifting with the movement of the first connecting rope 231. Furthermore, the provision of the first limiting protrusion 61 and the first limiting groove 81 facilitates the installation of the first protective sleeve 80. Operators can quickly and accurately complete installation by aligning the first limiting groove 81 with the first limiting protrusion 61, effectively improving installation efficiency.

[0080] Further, see Figure 3 as well as Figures 5 to 8 As shown, in this embodiment, a second protective sleeve 90 is sleeved on the second connecting rope 232, and a second limiting groove 91 is provided on one of the second protective sleeve 90 and the second avoidance channel 70, and a second limiting protrusion 71 adapted to the second limiting groove 91 is provided on the other. That is to say, in this embodiment, the second limiting groove 91 can be provided on the second avoidance channel 70 and the second limiting protrusion 71 can be provided on the second protective sleeve 90, or the second limiting protrusion 71 can be provided on the second avoidance channel 70 and the second limiting groove 91 can be provided on the second protective sleeve 90. Figure 6 The second avoidance channel 70 is provided with a second limiting protrusion 71, an attached Figure 3 FIG. 3 shows the situation when the second protective sleeve 90 is provided with a second limiting groove 91 .

[0081] Specifically, the second connecting rope 232 may come into contact with and rub against various surfaces during use. The provision of the second protective sleeve 90 can provide protection for the second connecting rope 232, reducing wear and tear caused by friction. Furthermore, during the movement of the second connecting rope 232, the second protective sleeve 90 may slide relative to the second avoiding passage 70 due to external forces or its own vibration. The cooperation between the second limiting protrusion 71 and the second limiting groove 91 can effectively secure the second protective sleeve 90 to the second avoidance passage 70, thereby preventing the second protective sleeve 90 from shifting as the second connecting rope 232 moves. Furthermore, the provision of the second limiting protrusion 71 and the second limiting groove 91 facilitates installation of the second protective sleeve 90. Operators can quickly and accurately complete installation by aligning the second limiting groove 91 with the second limiting protrusion 71, effectively improving installation efficiency.

[0082] Further, see Figure 6 As shown, the first protective sleeve 80 is provided with a first limiting groove 81, a first outer flange 82 and a second outer flange 83. The first limiting groove 81 is provided on the outer surface of the first protective sleeve 80 and is arranged around the circumference of the first protective sleeve 80, and there is a first limiting groove 81 between the first outer flange 82 and the second outer flange 83; a first limiting protrusion 61 is provided in the first avoidance channel 60, the first limiting protrusion 61 is provided on two opposite sides of the first avoidance channel 60, and there is a first avoidance gap 601 between the two first limiting protrusions 61, the first limiting groove 81 passes through the first avoidance gap 601 to cooperate with the first limiting protrusion 61 so that the first outer flange 82 abuts against the first limiting protrusion 61.

[0083] Specifically, see Figure 7 As shown, a first arcuate step 62 is also provided in the first avoidance channel 60 in this embodiment. The first arcuate step 62 is recessed toward the bottom of the first avoidance channel 60 , and when the first limiting groove 81 passes through the first avoidance gap 601 to cooperate with the first limiting protrusion 61 , the second outer flange 83 contacts the first arcuate step 62 .

[0084] Specifically, the cooperation between the first limiting groove 81 and the first limiting protrusion 61 provides a precise positioning function. When the first protective sleeve 80 is installed in the first avoidance channel 60, the first limiting protrusion 61 is embedded in the first limiting groove 81, which can accurately determine the position of the first protective sleeve 80 in the first avoidance channel 60. This makes the installation position of the first protective sleeve 80 more fixed and accurate, and avoids the impact of position deviation during use on its protective and other related functions. At the same time, the first outer flange 82 abuts against the first limiting protrusion 61, and the second outer flange 83 contacts the first arc-shaped step 62, thus forming a two-point support structure in the extension direction of the first avoidance channel 60. This structure can effectively prevent the first protective cover 80 from moving in the first avoidance channel 60. Moreover, the first limiting protrusion 61 and the first arc-shaped step 62 respectively generate resistance to the first outer flange 82 and the second outer flange 83 of the first protective cover 80, so that the first protective cover 80 is not easy to escape from the first avoidance channel 60 when subjected to external forces (such as vibration, slight collision, etc.).

[0085] Further, see Figure 7 As shown, the second protective sleeve 90 is provided with a second limiting groove 91, a third outer flange 92 and a fourth outer flange 93. The second limiting groove 91 is provided on the outer surface of the second protective sleeve 90 and is arranged around the circumference of the second protective sleeve 90, and a second limiting groove 91 is provided between the third outer flange 92 and the fourth outer flange 93; a second limiting protrusion 71 is provided in the second avoidance channel 70, and the second limiting protrusion 71 is provided on two opposite sides of the second avoidance channel 70, and a second avoidance gap 701 is provided between the two second limiting protrusions 71, and the second limiting groove 91 passes through the second avoidance gap 701 to cooperate with the second limiting protrusion 71 so that the third outer flange 92 abuts against the second limiting protrusion 71.

[0086] Specifically, see Figure 7 As shown, a second arc-shaped step 72 is also provided in the second avoidance channel 70 in this embodiment. The second arc-shaped step 72 is recessed toward the bottom of the second avoidance channel 70 , and when the second limiting groove 91 passes through the second avoidance gap 701 to cooperate with the second limiting protrusion 71 , the fourth outer flange 93 contacts the second arc-shaped step 72 .

[0087] Specifically, the cooperation between the second limiting groove 91 and the second limiting protrusion 71 provides a precise positioning function. When the second protective cover 90 is installed in the second avoidance channel 70, the second limiting protrusion 71 engages with the second limiting groove 91, accurately determining the position of the second protective cover 90 in the second avoidance channel 70. This makes the installation position of the second protective cover 90 more fixed and accurate, and avoids the impact of position deviation during use on its protective and other related functions. At the same time, the third outer flange 92 abuts against the second limiting protrusion 71, and the fourth outer flange 93 contacts the second arc-shaped step 72, thus forming a two-point support structure in the extension direction of the second avoidance channel 70. This structure can effectively prevent the second protective cover 90 from moving in the second avoidance channel 70. Moreover, the second limiting protrusion 71 and the second arc-shaped step 72 respectively generate resistance to the third outer flange 92 and the fourth outer flange 93 of the second protective cover 90, so that the second protective cover 90 is not easy to escape from the second avoidance channel 70 when subjected to external forces (such as vibration, slight collision, etc.).

[0088] Further, see Figures 10 and 11 As shown, the driving assembly 21 in this embodiment is provided with a photoelectric switch 27, and the rotating member 22 is provided with a first baffle 24, a second baffle 25 and a third baffle 26. The first baffle 24, the second baffle 25 and the third baffle 26 are arranged at intervals along the circumference of the rotating member 22 and protrude from the top surface of the rotating member 22. The rotating member 22 has a first position in which the first baffle 24 is rotated to block the photoelectric switch 27, a second position in which the second baffle 25 is rotated to block the photoelectric switch 27, and a third position in which the third baffle 26 is rotated to block the photoelectric switch 27; wherein, when the rotating member 22 is in the first position, the first cleaning member 11 is in a raised state and the second cleaning member 12 is in a lowered state; when the rotating member 22 is in the second position, the first cleaning member 11 and the second cleaning member 12 are both in a lowered state; when the rotating member 22 is in the third position, the first cleaning member 11 is in a lowered state and the second cleaning member 12 is in a raised state.

[0089] Specifically, this embodiment blocks the photoelectric switch 27 by means of the first baffle 24, the second baffle 25, and the third baffle 26, respectively, enabling the first cleaning member 11 and the second cleaning member 12 to switch between different operating states, thereby achieving diversified motion control of the first cleaning member 11 and the second cleaning member 12 to meet the needs of different cleaning scenarios. At the same time, the combination of a single photoelectric switch 27 and multiple baffles replaces the existing multi-sensor arrangement, simplifying the structure while reducing costs. The rotation angle of the rotating member 22 directly links the operating states of the first cleaning member 11 and the second cleaning member 12, enabling the control system to quickly respond and execute the corresponding cleaning strategy. Furthermore, the blocking state of the photoelectric switch 27 serves as the sole basis for judgment, avoiding the wear problem of mechanical contact limit switches and improving the reliability and service life of the system. At the same time, the arrangement of the three baffles forms a clear state boundary, preventing the first cleaning member 11 and the second cleaning member 12 from performing unexpected actions due to motor overload or transmission error.

[0090] Illustratively, the photoelectric switch 27 in this embodiment includes a grating switch.

[0091] Specifically, see Figure 10 As shown, in this embodiment, the line connecting the geometric center of the first baffle 24 and the geometric center of the rotating member 22 is a first line 241, the line connecting the geometric center of the second baffle 25 and the geometric center of the rotating member 22 is a second line 251, and the line connecting the geometric center of the third baffle 26 and the geometric center of the rotating member 22 is a third line 261. The angle θ1 between the first line 241 and the second line 251 is 122°, and the angle θ2 between the second line 251 and the third line 261 is 60°.

[0092] Specifically, combined Figure 11 As shown, the working conditions of the rotating member 22 of the present application are as follows:

[0093] (1) When the rotating member 22 is initially in the second position, the second baffle 25 blocks the photoelectric switch 27, and the photoelectric switch 27 detects no light. At this time, the first cleaning member 11 and the second cleaning member 12 are both in the lowered state;

[0094] (1-1) When the second cleaning member 12 needs to be raised, the driving assembly 21 only needs to control the rotating member 22 to rotate in the second direction until the photoelectric switch 27 is blocked by the third baffle 26 and is in the third position. The driving assembly 21 stops working, and finally the second cleaning member 12 is in the raised state and the first cleaning member 11 is in the lowered state.

[0095] (1-2) When the first cleaning member 11 needs to be lifted, it is only necessary to control the rotating member 22 to rotate in the first direction through the driving component 21 until the photoelectric switch 27 is blocked by the first baffle 24 and is in the first position. The driving component 21 stops working, and finally the first cleaning member 11 is in the lifted state and the second cleaning member 12 is in the lowered state.

[0096] (2) When the rotating member 22 is initially in the third position, the third baffle 26 blocks the photoelectric switch 27, and the photoelectric switch 27 detects no light. At this time, the first cleaning member 11 is in the lowered state, and the second cleaning member 12 is in the raised state;

[0097] (2-1) When the first cleaning member 11 and the second cleaning member 12 need to be simultaneously lowered, the driving assembly 21 only needs to control the rotating member to rotate in the first direction until the photoelectric switch 27 is blocked by the second baffle 25 and is in the second position. The driving assembly 21 stops working, and finally the first cleaning member 11 and the second cleaning member 12 are both lowered.

[0098] (2-2) When the first cleaning member 11 needs to be lifted, the driving component 21 is used to control the rotating member 22 to rotate in the first direction until the photoelectric switch 27 is blocked by the first baffle 24 and is in the first position. The driving component 21 stops working, and finally the first cleaning member 11 is in the lifted state and the second cleaning member 12 is in the lowered state.

[0099] (3) When the rotating member 22 is initially in the first position, the first baffle 24 blocks the photoelectric switch 27, and the photoelectric switch 27 detects no light. At this time, the first cleaning member 11 is in the raised state, and the second cleaning member 12 is in the lowered state;

[0100] (3-1) When the first cleaning member 11 and the second cleaning member 12 need to be simultaneously in the lowered state, the driving assembly 21 only needs to control the rotating member 22 to rotate in the second direction until the photoelectric switch 27 is blocked by the second baffle 25 and is in the second position. The driving assembly 21 stops working, and finally the first cleaning member 11 and the second cleaning member 12 are both in the lowered state.

[0101] (3-2) When the second cleaning member 12 needs to be lifted, the driving assembly 21 is used to control the rotating member 22 to rotate in the second direction until the photoelectric switch 27 is blocked by the third baffle 26 and is in the third position, thereby finally making the first cleaning member 11 in a lowered state and the second cleaning member 12 in a raised state.

[0102] (4) When the photoelectric switch 27 is between the first position and the second position, or between the second position and the third position, the photoelectric switch 27 is not blocked by the baffle and detects light, and a reset operation needs to be performed at this time; using current protection, the driving component 21 is rotated forward and runs until it is blocked. At this time, the second cleaning member 12 is in a raised state, and the photoelectric switch 27 is blocked by the third baffle 26 and is in the third position, and then the above steps (2-1) and (2-2) can be repeated; or, using current protection, the driving component 21 is reversed and runs until it is blocked. At this time, the first cleaning member 11 is in a raised state, and the photoelectric switch 27 is blocked by the first baffle 24 and is in the first position, and then the above steps (3-1) and (3-2) can be repeated.

[0103] On the other hand, the embodiment of the present application further provides a cleaning system, which includes the above-mentioned cleaning device, and therefore, the cleaning system includes all the technical effects of the above-mentioned cleaning device. Since the technical effects of the cleaning device have been described in detail above, they will not be repeated here.

[0104] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0105] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0106] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
