[0002] With the increasing demand for household cleaning, cleaning devices represented by sweep-and-mop integrated machines have been widely favored by users. Cleaning devices can clean floors and carpets, greatly reducing the workload of users and shortening the daily cleaning time. When cleaning the floor, the fluff on the roller is used to clean the floor. However, when encountering a carpet, the fluff on the roller is likely to come into contact with the carpet, causing the water stains or stains on the fluff to be transferred to the carpet, thereby polluting the carpet and resulting in a poor user experience.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0046] As Figure 1 As shown, an embodiment of the present application provides a cleaning device, which can be a mopping robot or a sweeping and mopping integrated robot. Among them, the mopping robot uses a mop arranged on a roller to mop and clean the ground, and the sweeping and mopping integrated robot uses a mopping and wiping member arranged on a roller to sweep and mop the ground. For the convenience of description, the present application takes the mopping robot as an example for illustration.

[0047] When the mopping robot moves on the ground, the mop arranged on the roller moves along with the device body. At the same time, the roller drives the mop to rotate itself, so that a sliding friction is generated between the rotating mop and the surface to be cleaned, realizing the mopping and cleaning of the surface to be cleaned. The surface to be cleaned can be, for example, a floor, a staircase, etc. However, when the cleaning device encounters a carpet, the fluff on the mop is likely to come into contact with the carpet, causing the water stains or stains on the fluff to be transferred to the carpet, thereby polluting the carpet and resulting in a poor user experience.

[0048] To this end, the cleaning device provided by the embodiment of the present application can prevent the stains on the roller from contaminating the carpet by using the shielding member to shield the roller when the cleaning task is performed by the roller, thereby improving the user experience. The specific structure of the cleaning device will be described in detail below with reference to the accompanying drawings.

[0049] As Figure 1 and Figure 2 shown, the embodiment of the present application provides a cleaning device, including: a body 3, a cleaning component 2, and a shielding component 1.

[0050] The body 3 has a receiving cavity 30 and an opening 31 communicating with the receiving cavity 30. The cleaning component 2 is located in the receiving cavity 30, and the cleaning component 2 includes a roller 21 that can rotate around its own axis. A fluffy mop is sleeved on the outer peripheral side of the roller 21. The rotating fluffy mop generates a sliding friction with the surface to be cleaned, so as to realize the mopping and cleaning of the surface to be cleaned.

[0051] The shielding component 1 is located in the receiving cavity 30 and is adjacent to the cleaning component 2. The shielding component 1 includes a movable shielding member 11. In the first state, the shielding member 11 opens the opening 31, so that the roller 21 can clean the surface to be cleaned through the opening 31; in the second state, the shielding member 11 closes the opening 31 to shield the roller 21.

[0052] In this embodiment, in the first state, the task of the cleaning device is to move and clean hard surfaces such as the floor according to a preset path plan. The shielding member 11 opens the opening 31 by rotating, so that a part of the fluffy mop is exposed through the opening 31 by the roller 21, and the roller 21 rotates to clean the surface to be cleaned. When the cleaning device moves to a flexible surface such as a carpet, it enters the second state. In order to prevent the carpet from curling and affecting the movement of the cleaning device, the shielding member 11 closes the opening 31 to shield the roller 21, preventing the stains on the roller from contaminating the carpet and improving the user experience.

[0053] In addition, since a fluffy mop is sleeved on the outer peripheral side of the roller 21 and the fluffy mop is a flexible member with a certain deformation amount, when the shielding member 11 closes the opening 31, the shielding member 11 compresses the fluffy mop into the receiving cavity 30. When the shielding member 11 opens the opening 31, the fluffy mop is thrown away under the action of centrifugal force during the rotation of the roller 21 and is used to clean the surface to be cleaned.

[0054] Furthermore, the cleaning assembly 2 is movable relative to the opening 31 to approach or move away from the opening 31, so as to avoid the friction between the shielding member 11 and the fluff mopping cloth, which may affect the opening or closing of the opening 31. There are various ways to implement its structure. For example, the cleaning assembly 2 realizes the lifting movement in the vertical direction through a lifting mechanism, or the cleaning assembly 2 realizes the rotational movement through a flipping mechanism. There is no limitation here, and all are within the protection scope of this application. In addition, there are also various ways to implement the structure for the shielding member 11 to open or close the opening 31. For example, a gear transmission mechanism, a crank and connecting rod mechanism, a pulley mechanism, etc. There is no limitation here, and all are within the protection scope of this application.

[0055] The cleaning device provided by the embodiment of this application includes a shielding assembly 1 disposed adjacent to the cleaning assembly 2 in the accommodating cavity 30 of the machine body 3, and the shielding assembly 1 includes a movable shielding member 11. In the first state, the shielding member 11 opens the opening 31 of the accommodating cavity 30, so that the roller 21 cleans the surface to be cleaned through the opening 31; in the second state, the shielding member 11 closes the opening 31 to shield the roller 21. Thus, the cleaning device completes the cleaning task through the roller 21 in the first state, and when encountering a carpet in the second state, the roller 21 can be shielded by the shielding member 11 to prevent the stains on the roller 21 from contaminating the carpet, improving the user experience.

[0056] In some embodiments, the cleaning device further includes a lifting mechanism (not shown in the figure) located in the accommodating cavity 30. One end of the lifting mechanism is fixedly connected to the machine body 3, and the other end of the lifting mechanism drives the cleaning assembly 2 to perform a linear motion. In the first state, the lifting mechanism drives the roller 21 to descend to approach the opening 31; in the second state, the lifting mechanism drives the roller 21 to ascend to move away from the opening 31.

[0057] As described above, the cleaning assembly 2 is movable relative to the opening 31 to approach or move away from the opening 31, and there are various ways to implement its structure. In this embodiment, a lifting mechanism is used to drive the cleaning assembly 2 to rotate to approach or move away from the opening 31, so that when the roller 21 approaches the opening 31, the shielding member 11 opens the opening 31, and when the roller 21 moves away from the opening 31, the shielding member 11 closes the opening 31. The entire operation process is smooth without structural interference. The lifting mechanism can be, for example, a slide rail disposed in the vertical direction and a slider slidably connected to the slide rail. The cleaning assembly 2 is connected to the slider, and the slider is driven by a motor, a cylinder or a hydraulic cylinder, so as to drive the cleaning assembly 2 to descend or ascend, so that the roller 21 approaches or moves away from the opening 31.

[0058] In some embodiments, the cleaning device further includes a flipping mechanism 23 located in the accommodating cavity 30. One end of the flipping mechanism 23 is rotatably connected to the body 3, and the other end of the flipping mechanism 23 drives the cleaning assembly 2 to rotate around an axis L parallel to the axial direction of the drum 21. In the first state, the flipping mechanism 23 drives the drum 21 to rotate closer to the opening 31; in the second state, the flipping mechanism 23 drives the drum 21 to rotate in the opposite direction to move away from the opening 31. Compared with the lifting mechanism, the flipping mechanism 23 can reduce the occupied space of the cleaning device in the vertical direction and further improve the compactness of the cleaning device.

[0059] As described above, the cleaning assembly 2 is movable relative to the opening 31 to approach or move away from the opening 31, and there can be various structural implementation methods. In this embodiment, the flipping mechanism 23 is used to drive the cleaning assembly 2 to rotate to approach or move away from the opening 31, and the flipping mechanism 23 rotates around an axis L parallel to the axial direction of the drum 21. On the one hand, it can reduce the occupied space of the cleaning device in the vertical direction and improve the structural compactness of the cleaning device. On the other hand, the flipping mechanism 23 can cooperate with the rotational movement of the shielding assembly 1 without interference, so that the shielding member 11 opens the opening 31 while the drum 21 approaches the opening 31, and the shielding member 11 closes the opening 31 while the drum 21 moves away from the opening 31. The entire operation process is smooth without structural interference, reducing the occupied space of the accommodating cavity 30 and further improving the compactness of the cleaning device.

[0060] In some embodiments, the shielding member 11 is an arc-shaped structural member provided on the outer peripheral side of the drum 21, and the shielding member 11 opens or closes the opening 31 by rotating.

[0061] As Figure 1 shown, the flipping mechanism 23 is rotatably connected to the cleaning assembly 2, the shielding member 11 is coaxially arranged with the drum 21, and the rotational direction of the shielding member 11 is the same as the rotational direction of the flipping mechanism 23. As shown by the arrow direction in the figure, in the first state, the flipping mechanism 23 drives the cleaning assembly 2 to rotate counterclockwise along the direction M around the rotation axis of the body 3 to approach the opening 31. At the same time, the shielding member 11 rotates counterclockwise along the direction N around the central axis of the drum 21 to open the opening 31, and the drum 21 is exposed from the opening 31 to perform tasks such as cleaning the floor. As Figure 2 shown, in the second state, the flipping mechanism 23 drives the cleaning assembly 2 to rotate clockwise along the direction M around the rotation axis of the body 3 to move away from the opening 31. At the same time, the shielding member 11 rotates clockwise along the direction N around the central axis of the drum 21 to close the opening 31, so that the shielding member 11 can shield foreign matters such as stains falling from the drum 21, preventing stains and other foreign matters from overflowing from the opening 31 and polluting the carpet. This not only meets the requirements for the structural compactness of the cleaning device but also ensures that there is no interference during the movement process, enhancing the user experience.

[0062] Further, the shielding component 1 further includes a driving motor 12 and a transmission mechanism 13. The input end of the transmission mechanism 13 is connected to the output shaft of the driving motor 12, and the output end of the transmission mechanism 13 is connected to the shielding member 11 to drive the shielding member 11 to rotate.

[0063] As Figure 1 shown, the driving motor 12 is fixedly connected to the flipping mechanism 23. On the one hand, it can ensure the synchronous movement of the drum 21 and the shielding member 11. On the other hand, it can reduce the occupied space of the accommodating cavity 30 and further improve the structural compactness of the cleaning device.

[0064] In some embodiments, the transmission mechanism 13 includes a gear 131 and an arc-shaped gear ring 132 that mesh with each other. The gear 131 is connected to the output shaft of the driving motor 12, and the arc-shaped gear ring 132 is fixedly connected to or integrally formed with the shielding member 11.

[0065] As described above, there are various structural implementation methods for the shielding member 11 to open the opening 31 by rotation and close the opening 31 by reverse rotation, such as a gear transmission mechanism, a crank and connecting rod mechanism, a pulley mechanism, etc. As Figure 3 shown, in this embodiment, a gear transmission mechanism is adopted, which can simplify the transmission mechanism 13 and is easy to implement. The arc-shaped gear ring 132 is fixedly connected to or integrally formed with the shielding member 11, which can ensure the synchronous rotation of the arc-shaped gear ring 132 and the shielding member 11, reduce the movement error between the two, and improve the movement accuracy.

[0066] Further, the cleaning component 2 further includes an arc-shaped outer shell 22. The arc-shaped outer shell 22 is arranged on the outer peripheral side of the drum 21 and is rotatably connected to the drum 21. The arc-shaped outer shell 22 is provided with an arc-shaped chute 220, and the shielding member 11 is movable along the arc-shaped chute 220.

[0067] As Figure 2 and Figure 3 shown, the arc-shaped outer shell 22 covers the outer peripheral side of the drum 21. The axial two ends of the arc-shaped outer shell 22 and the axial two ends of the drum 21 are cooperated through a rotating shaft to realize the rotation of the drum 21. An arc-shaped structure is arranged on the side of the arc-shaped outer shell 22 away from the drum 21. An arc-shaped chute 220 is arranged on the arc-shaped structure. A convex portion 111 extending along the arc length direction is arranged on the shielding member 11. The convex portion 111 can be accommodated in the arc-shaped chute 220 so that the shielding member 11 is movable along the arc-shaped chute 220 to shield the drum 21 or expose the drum 21. Such a setting can reduce the number of parts and further improve the structural compactness of the cleaning device.

[0068] In addition, the cleaning component 2 further includes components such as a motor for driving the drum 21 to rotate (not shown in the figure) and will not be elaborated.

[0069] Further, the arc-shaped gear ring 132 has a first end close to the opening 31 and a second end far from the opening 31 along its arc length direction, and the gear 131 and the driving motor 12 are arranged close to the first end.

[0070] As Figure 2 and Figure 3 shown, the arc-shaped gear ring 132 is integrally formed with the shielding member 11, and the gear 131 and the driving motor 12 are arranged close to the first end of the arc-shaped gear ring 132, which can ensure that the shielding member 11 extends a sufficient length to shield the roller 21 while the rotation angle of the arc-shaped gear ring 132 is as small as possible, reduce the occupied space of the transmission mechanism 13 in the vertical direction, and further improve the structural compactness of the cleaning device.

[0071] Further, in the first state, the central angle corresponding to the orthographic projection of the opening 31 on the roller 21 is α, and the central angle of the arc-shaped gear ring 132 is β, and the following relationship is satisfied: β > 1 / 2 * α.

[0072] As Figure 1 and Figure 2 shown, the arc-shaped gear ring 132 is integrally formed with the shielding member 11. In the first state, the roller 21 is close to the opening 31, the central angle of the roller 21 corresponding to the opening 31 is α, and the central angle of the arc-shaped gear ring 132 is β; in the second state, the roller 21 is far from the opening 31, and the arc length required for the shielding member 11 to shield the roller 21 is less than the length dimension of the opening 31. At the same time, considering that the shielding member 11 needs to extend a sufficient length to shield the roller 21 and can expose the roller 21 and open the opening 31 when the roller 21 needs to be exposed to perform the task of cleaning the floor, the central angle β of the arc-shaped gear ring 132 and the central angle α of the roller 21 satisfy the following relationship: β > 1 / 2 * α. That is to say, the use requirements of the shielding member 11 can be ensured while the rotation angle of the arc-shaped gear ring 132 is as small as possible.

[0073] Optionally, α = 120° - 150°, β > 60°; in one example, α = 130°, β = 160°.

[0074] In some embodiments, the arc length of the shielding member 11 is greater than or equal to the arc length of the arc-shaped gear ring 132. Since the rotation angle of the arc-shaped gear ring 132 is restricted by the structure of the arc-shaped housing 22 or the flipping mechanism 23 and may not be able to rotate through a large angle, the arc length of the arc-shaped gear ring 132 is to ensure that it can always mesh with the gear 131. The arc length of the shielding member 11 is to ensure that it extends out a sufficient length to shield the drum 21, and at the same time, the length of the shielding member 11 can be fully opened at the opening 31 when the drum 21 needs to be exposed to perform the task of cleaning the floor without affecting the normal operation of the cleaning device. Thus, the arc length of the shielding member 11 being greater than or equal to the arc length of the arc-shaped gear ring 132 can ensure the usage requirements of the shielding member 11 while keeping the rotation angle of the arc-shaped gear ring 132 as small as possible.

[0075] It can be understood that the size of the opening 31 of the accommodation cavity 30 of the body 3, the central angle β of the arc-shaped gear ring 132, and the arc length of the shielding member 11 are determined according to specific application scenarios and are not limited.

[0076] In some embodiments, the number of the transmission mechanisms 13 and the driving motors 12 is at least two respectively, and the at least two transmission mechanisms 13 and driving motors 12 are spaced apart along the axial direction of the drum 21.

[0077] As Figure 4 shown, the number of the transmission mechanisms 13 and the driving motors 12 is two respectively, and the two transmission mechanisms 13 and driving motors 12 are spaced apart along the axial direction of the drum 21. Such a setting can ensure that the overall structure of the shielding member 11 remains balanced during rotation and avoid deflection that may affect the normal operation of the cleaning device.

[0078] It can be understood that when the cleaning device is large in volume and the drum 21 is long in length, three or more transmission mechanisms 13 and driving motors 12 can also be provided to drive the shielding member 11 to rotate to ensure the normal operation of the cleaning device.

[0079] Figure 5 Fig. shows a schematic structural diagram of a cleaning device provided by another embodiment of the present application. Figure 6 Fig. shows Figure 5 a top view of the cleaning device shown in Fig.

[0080] As Figure 5 and Figure 6 shown, the embodiments of the present application further provide a cleaning device, which is similar in structure to the cleaning device shown in Figures 1 to 4 Fig., and the shielding members 11 of the shielding assembly 1 shield the opening of the body 3 by rotating. The difference lies in that the transmission mechanisms 13 for driving the shielding members 11 to rotate are different.

[0081] Specifically, the transmission mechanism 13 includes a crank 133 and a connecting rod 134. The crank 133 is connected to the output shaft of the driving motor 12. One end of the connecting rod 134 is rotatably connected to the crank 133, and the other end of the connecting rod 134 is rotatably connected to the shielding member 11.

[0082] The driving motor 12 drives the crank 133 to rotate, driving the connecting rod 134 to rotate accordingly, so that the shielding member 11 rotates around the outer peripheral side of the drum 21, thereby opening or closing the opening 31. The length dimensions of the crank 133 and the connecting rod 134 are determined according to specific application scenarios and structural layouts, and are not limited here.

[0083] Furthermore, the cleaning assembly 2 further includes an arc-shaped housing 22. The arc-shaped housing 22 is disposed on the outer peripheral side of the drum 21 and is rotatably connected to the drum 21. The arc-shaped housing 22 is provided with an arc-shaped chute 220, and the shielding member 11 is movable along the arc-shaped chute 220.

[0084] As Figure 5 shown, the arc-shaped housing 22 covers the outer peripheral side of the drum 21. The axial two ends of the arc-shaped housing 22 and the axial two ends of the drum 21 are cooperated through a rotating shaft to realize the rotation of the drum 21. The shielding member 11 is located between the arc-shaped housing 22 and the drum 21. The arc-shaped housing 22 is provided with an arc-shaped chute 220 along the arc length direction. The shielding member 11 is provided with a convex portion (not shown in the figure) extending along the arc length direction. The convex portion can be received in the arc-shaped chute 220. One end of the connecting rod 134 away from the crank 33 passes through the arc-shaped chute 220 and is rotatably connected to the shielding member 11, so that the shielding member 11 can move along the arc-shaped chute 220 and shield or expose the drum 21. Such a setting can reduce the number of parts and further improve the structural compactness of the cleaning device.

[0085] Furthermore, the number of the transmission mechanisms 13 and the driving motors 12 is at least two respectively, and at least two transmission mechanisms 13 and driving motors 12 are spaced apart along the axial direction of the drum 21.

[0086] As Figure 6 shown, two arc-shaped chutes 220 are spaced apart along the axial direction of the arc-shaped housing 22 of the drum 21. One ends of the connecting rods 134 of the two transmission mechanisms 13 away from the crank 33 respectively pass through the corresponding arc-shaped chutes 220 and are rotatably connected to the shielding member 11. Such a setting can ensure that the overall structure of the shielding member 11 remains balanced during the rotation process and avoid deflection from affecting the normal operation of the cleaning device.

[0088] Figure 11 shown Figure 7 Schematic diagram of the shielding component of the cleaning device shown; Figure 12 shown Figure 7 Schematic diagram of the transmission component of the cleaning device shown.

[0089] As Figures 7 to 10 shown, an embodiment of the present application also provides a cleaning device, which is similar in structure to the cleaning device shown, except that the shielding member 11 of the shielding component 1 shields the opening of the body 3 by moving. Figures 1 to 6 Specifically, in the first state, the task of the cleaning device is to move and clean hard surfaces such as the floor according to a preset path plan. The cleaning component 2 approaches the opening 31, and at the same time, the shielding member 11 opens the opening 31 by moving along a preset direction, so that part of the fluffy mop is exposed through the opening 31 by the roller 21, and the roller 21 rotates to clean the surface to be cleaned. When the cleaning device moves to a flexible surface such as a carpet, it enters the second state. The cleaning component 2 moves away from the opening 31 to prevent the carpet from curling and affecting the movement of the cleaning device. At the same time, the shielding member 11 closes the opening 31 by moving in the reverse direction along the preset direction to shield the roller 21 and prevent the stains on the roller from contaminating the carpet, improving the user experience.

[0090] In addition, the preset direction can be a direction perpendicular to the axial direction of the roller or a direction parallel to the axial direction of the roller, depending on the specific application scenario and structural layout, and will not be elaborated here.

[0091] Furthermore, the cleaning component 2 is movable relative to the opening 31 to approach or move away from the opening 31, and there are various ways to implement its structure. For example, the cleaning component 2 realizes the lifting movement in the vertical direction through a lifting mechanism, or the cleaning component 2 realizes the rotational movement through a flipping mechanism. As mentioned above, all are within the protection scope of the present application. In addition, there are also various ways to implement the opening of the opening 31 by moving the shielding member 11 along the preset direction and closing the opening 31 by moving in the reverse direction along the preset direction, such as a gear transmission mechanism, a crank connecting rod mechanism, a pulley mechanism, a conveyor belt assembly, a conveyor chain assembly, etc. There is no limitation here, and all are within the protection scope of the present application.

[0092] In some embodiments, the shielding member 11 is a rolling curtain with a preset length, and the shielding member 11 can extend or contract along the preset direction to open or close the opening 31.

[0093] In some embodiments, the shielding member 11 is a rolling curtain with a preset length, and the shielding member 11 can extend or contract along the preset direction to open or close the opening 31.

[0094] AsFigure 9 and Figure 10 As shown in , the flip mechanism is rotatably connected to the cleaning assembly 2, and the shielding member 11 is a rolling curtain with a preset length, which can be extended or retracted along a preset direction. As shown in Figure 9 As shown in the direction of the arrow M, in the first state, the flip mechanism drives the cleaning assembly 2 to rotate around the rotating axis of the machine body 3 to approach the opening 31. At the same time, the roller curtain of the shielding member 11 is in a retracted state to open the opening 31, and the roller 21 is exposed from the opening 31 to perform tasks such as cleaning the floor. As Figure 10 As shown in the figure, in the second state, the flip mechanism 23 drives the cleaning assembly 2 to rotate in the opposite direction around the rotating axis of the body 3 to move away from the opening 31. At the same time, the shielding member 11 extends in a preset direction to close the opening 31, so that the shielding member 11 can block foreign objects such as stains falling from the drum 21, and prevent foreign objects such as stains from overflowing from the opening 31 and contaminating the carpet, which not only meets the structural compactness requirements of the cleaning device, but also ensures that there will be no interference in the movement process, thereby improving the user experience.

[0095] Furthermore, the shielding assembly 1 also includes a guide rod 15 and a drum 16, the drum 16 is detachably connected to the body 3, one end of the rolling curtain is wound around the drum 16, and the other end of the rolling curtain is wound around the guide rod 15, and the guide rod 15 can drive the shielding member 11 to extend or contract along a preset direction.

[0096] If Figure 7 and Figure 11 As shown, the side wall of the accommodating cavity 30 of the body 3 is provided with a groove, the roller 16 can be placed in the groove, one end of the rolling curtain is wound around the roller 16, and the other end of the rolling curtain is wound around the guide rod 15, and the guide rod 15 can drive the shielding member 11 to extend or contract along the first direction X. With such a configuration, the shielding assembly 1 can be detachably connected to the body 3, so that when the shielding member 11 blocks a lot of foreign objects such as stains dropped from the drum 21, the rolling curtain of the shielding member 11 can be disassembled for cleaning or replacement and maintenance, further improving the user experience.

[0097] Furthermore, the cleaning device also includes a driving motor 12 and a transmission assembly 13. The transmission assembly 13 is arranged at both ends of the axial direction of the guide rod 15. The output shaft of the driving motor 12 is connected to the input end of the transmission assembly 13. The transmission assembly 13 drives the guide rod 15 to drive the shielding member 11 to extend or contract along the first direction X perpendicular to the axial direction of the drum 21.

[0098] If Figure 7 ​​As shown, the output shaft of the drive motor 12 is connected to the input end of the transmission assembly. The transmission assembly is arranged at both axial ends of the guide rod 15. When the preset direction is the first direction X perpendicular to the axial direction of the drum 21, the overall occupied space of the shielding assembly can be reduced. The transmission assembly drives the guide rod 15 to drive the shielding member 11 to extend or contract along the first direction X, which can ensure that the shielding member 11 remains balanced during movement and will not deflect.

[0099] In some embodiments, the transmission assembly 13 includes a first conveyor belt assembly 161 and a second conveyor belt assembly 162. The output shaft of the drive motor 12 is connected to the driving pulley 16a of either the first conveyor belt assembly 161 or the second conveyor belt assembly 162. Axial ends of the guide rod 15 are respectively embedded in the conveyor belts 16c of the first conveyor belt assembly 161 and the second conveyor belt assembly 162.

[0100] As Figure 7 and Figure 12 shown, the transmission assembly includes a first conveyor belt assembly 161 and a second conveyor belt assembly 162. The first conveyor belt assembly 161 and the second conveyor belt assembly 162 respectively include a driving pulley 16a, a driven pulley 16b, and a conveyor belt 16c. Axial ends of the guide rod 15 are respectively embedded in the conveyor belts 16c of the first conveyor belt assembly 161 and the second conveyor belt assembly 162. When the drive motor 12 drives the driving pulley 16a of either the first conveyor belt assembly 161 or the second conveyor belt assembly 162 to rotate, it will drive the guide rod 15 to move along the first direction X, and further cause the shielding member 11 to extend or contract along the first direction X.

[0101] In some embodiments, the transmission assembly 13 includes a first conveyor chain assembly and a second conveyor chain assembly. The output shaft of the drive motor 12 is connected to the driving sprocket of either the first conveyor chain assembly or the second conveyor chain assembly. Axial ends of the guide rod 15 are respectively embedded in the conveyor chains of the first conveyor chain assembly and the second conveyor chain assembly.

[0102] The transmission assembly 13 includes a first conveyor chain assembly and a second conveyor chain assembly. The first conveyor chain assembly and the second conveyor chain assembly respectively include a driving sprocket, a driven sprocket, and a conveyor chain. Axial ends of the guide rod 15 are respectively embedded in the conveyor chains of the first conveyor chain assembly and the second conveyor chain assembly. When the drive motor 12 drives the driving sprocket of either the first conveyor chain assembly or the second conveyor chain assembly to rotate, it will drive the guide rod 15 to move along the first direction X, and further cause the shielding member 11 to extend or contract along the first direction X.

[0103] In some embodiments, the ratio of the length of the rolling curtain to the length of the opening 31 along the first direction X is 2 to 3. The unit 3 has a storage space for the rolling curtain. Under the premise that the diameter of the rolling curtain in the retracted state can be placed in the storage space, the length of the rolling curtain can be made in different batches to adapt to cleaning equipment of different sizes and corresponding openings 31.

[0104] It can be understood that the size of the opening 31 of the accommodating cavity 30 of the body 3 and the length of the rolling curtain of the shielding member 11 are determined according to the specific application scenario and are not specifically limited.

[0105] In some embodiments, the body 3 includes a pair of side plates 33 forming the accommodating cavity 30, the pair of side plates 33 are respectively arranged at the axial ends of the drum 21, and the transmission assembly is arranged on the end surfaces of the pair of side plates 33 along the height direction.

[0106] If Figure 8 As shown, in order to facilitate the fixing of the transmission assembly, the first conveyor belt assembly 161 and the second conveyor belt assembly 162 are respectively arranged on the end surface of the corresponding side plate 33 along the height direction, and are detachably connected to the side plate 33 through the cover plate 16d. For example, a plurality of first threaded holes are arranged on the end surface of the side plate 33 along the height direction, and a plurality of first through holes are correspondingly arranged on the cover plate 16d. Fasteners such as screws are passed through the first through holes on the cover plate 16d and are threadedly connected to the first threaded holes of the side plate 33, so that the shielding assembly 1 can be disassembled for cleaning or replacement and maintenance.

[0107] Furthermore, the body 3 also includes a sealing plate 34, which covers the accommodating cavity 30 and is detachably connected to the end surface of the side plate 33, and the sealing plate 34 is provided with an opening 31. A plurality of second threaded holes are provided on the end surface of the side plate 33 along the height direction, and a plurality of second through holes are correspondingly provided on the sealing plate 34. Fasteners such as screws pass through the second through holes on the sealing plate 34 and are threadedly connected to the second threaded holes of the side plate 33, so as to facilitate the disassembly of the shielding assembly 1 and the cleaning assembly for maintenance.

[0108] Furthermore, the drive motor 12 is fixedly connected to any one of the pair of side plates 33, and the drive motor 12 is located on the side of the side plate 33 away from the accommodating cavity 30.

[0109] If Figure 7 As shown in FIG. 1 , the drive motor 12 is fixedly connected to any one of the side plates 33 of the pair of side plates 33. The side plates 33 are provided with avoidance grooves 14 corresponding to the position of the drive motor. The drive motor 12 is located on the side of the side plate 33 away from the accommodating chamber 30. Such a configuration can reduce the occupied space of the accommodating chamber 30 and further improve the compactness of the cleaning device.

[0110] The following describes the technical solution provided by this embodiment in combination with specific application scenarios.

[0111] Application scenario 1​​

[0112] As Figure 1 and Figure 2 shown, the cleaning device is a mopping robot, the surface to be cleaned is the floor of the user's living room, and a carpet is laid at a specific position on the floor. A fluffy mop cloth is sleeved on the outer peripheral side of the roller 21 of the cleaning assembly 2, the shielding member 11 is an arc-shaped structural member arranged on the outer peripheral side of the roller 21, and the transmission mechanism 13 for driving the shielding member 11 to rotate is a gear 131 and an arc-shaped gear ring 132, or a crank 133 and a connecting rod 134.

[0113] When the user starts the cleaning device to perform a cleaning task, the cleaning device moves on the floor of the living room according to a preset path plan. The flipping mechanism 23 drives the cleaning assembly 2 to rotate counterclockwise along the rotation axis of the body 3 to approach the opening 31. At the same time, the shielding member 11 rotates counterclockwise along the central axis of the roller 21 to open the opening 31, and the roller 21 is exposed from the opening 31. Sliding friction can be generated between the rotating fluffy mop cloth and the floor to wipe stains and other foreign matters on the floor onto the fluffy mop cloth.

[0114] When the cleaning device moves to the carpet, the flipping mechanism 23 drives the cleaning assembly 2 to rotate clockwise along the rotation axis of the body 3 to move away from the opening 31. At the same time, the shielding member 11 rotates clockwise along the central axis of the roller 21 to close the opening 31, so that the shielding member 11 can block stains and other foreign matters falling from the roller 21, and prevent stains and other foreign matters from overflowing from the opening 31 and polluting the carpet. This mopping robot can complete the task of cleaning the floor through the roller 21, and at the same time, when encountering a carpet, it can also use the shielding member 11 to block the roller 21 to prevent the stains of the roller 21 from polluting the carpet, improving the user experience.

[0115] Application scenario two

[0116] As Figure 9 and Figure 10 shown, the cleaning device is a mopping robot, the surface to be cleaned is the floor of the user's living room, and a carpet is laid at a specific position on the floor. A fluffy mop cloth is sleeved on the outer peripheral side of the roller 21 of the cleaning assembly 2, the shielding member 11 is a rolling curtain with a preset length, and the transmission mechanism 13 for driving the shielding member 11 to move includes a first conveyor belt assembly 161 and a second conveyor belt assembly 162, or a first conveyor chain assembly and a second conveyor chain assembly.

[0117] When the user starts the cleaning device to perform a cleaning task, the cleaning device moves on the floor of the living room according to a preset path plan. The flipping mechanism drives the cleaning component 2 to rotate around the rotation axis of the machine body 3 to approach the opening 31. At the same time, the roller blind of the shielding member 11 moves in the first direction X perpendicular to the axial direction of the roller 21 to open the opening 31 of the accommodating cavity 30, and the roller 21 is exposed from the opening 31. Sliding friction can be generated between the rotating fluffy mop and the floor to wipe stains and other foreign objects on the floor onto the fluffy mop.

[0118] When the cleaning device moves to the carpet, the flipping mechanism drives the cleaning component 2 to rotate in the reverse direction around the rotation axis of the machine body 3 to move away from the opening 31. At the same time, the shielding member 11 moves in the reverse direction of the first direction X to close the opening 31, so that the shielding member 11 can block stains and other foreign objects falling from the roller 21, avoiding stains and other foreign objects from overflowing from the opening 31 and polluting the carpet. This mopping robot can complete the task of cleaning the floor through the roller 21, and at the same time, when encountering a carpet, it can also use the shielding member 11 to block the roller 21 to prevent the stains on the roller 21 from polluting the carpet, improving the user experience.
