[0002] This application claims priority to Chinese patent application No. 2024103795216, filed on March 29, 2024. Technical Field

[0003] This application belongs to the field of cleaning equipment technology, and in particular relates to a cleaning device and a cleaning system. Background Technology

[0004] With the iterative updates and development of technology, cleaning equipment has entered ordinary household life and gradually become widespread. As cleaning equipment moves across the ground, it cleans the surface by contacting and rubbing its integrated cleaning components against the surface to be cleaned.

[0005] Currently, when the cleaning components in the cleaning equipment do not need to contact the surface to be cleaned, the common practice is to control the robot to avoid the area where the surface to be cleaned is located, or to control the robot to lift the cleaning components. However, controlling the robot to avoid the area where the surface to be cleaned is located can easily disrupt the cleaning plan of the cleaning equipment, while controlling the robot to lift the cleaning components does not completely achieve physical isolation between the surface to be cleaned and the cleaning components. Therefore, the current practices need to be improved. Utility Model Content

[0091] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0092] The following is for reference. Figures 1-29 This application describes a cleaning device and a cleaning apparatus according to embodiments thereof.

[0093] This application provides a cleaning device, such as... Figures 1-6 As shown, the cleaning device includes a body (not shown in the attached drawings), a support 100, a cleaning component 200, a drive mechanism 300, and a shielding component 400.

[0094] The bracket 100 is used to movably mount the cleaning component 200 at the bottom of the body of the cleaning equipment. The bracket 100 and the body can be fixedly connected or movably connected. For example, in some embodiments, the bracket 100 and the body are fixedly connected, and the cleaning component 200 can move vertically relative to the bracket 100. In other embodiments, the bracket 100 and the body are movably connected, and the bracket 100 can drive the cleaning component 200 to move vertically.

[0095] It should be noted that the vertical direction mentioned in this application refers to the height direction of the cleaning equipment.

[0096] In one embodiment, the bracket 100 is arranged to form an accommodating space, in which the cleaning component 200, the drive mechanism 300, and the shielding member 400 are at least partially disposed.

[0097] As shown in Figures 1-6 The cleaning assembly 200 includes a housing 210 and a cleaning member 220. The housing 210 is arranged in and connected with the support 100, and the support 100 is provided with a receiving cavity. The cleaning member 220 is rotatably arranged in the receiving cavity. In an embodiment, the housing 210 can be in a semi-cylindrical structure, and the bottom of the housing 210 is a cavity. The cleaning member 220 is arranged below the housing 210 and in the cavity of the housing 210.

[0098] As shown in Figures 1-6 In some embodiments, the housing 210 is movably connected with the support 100, and specifically, the housing 210 is movably arranged on the support 100 in the vertical direction, so that the housing 210 can be raised and lowered relative to the support 100 in the vertical direction. In other embodiments, the housing 210 is fixedly connected with the support 100, and the housing 210 and the support 100 are synchronously raised and lowered in the vertical direction. Details are described below.

[0099] The cleaning member 220 can include but is not limited to a dry cleaning member and a wet cleaning member. The dry cleaning member can include a roller brush or other types of dry cleaning members. The wet cleaning member can include a flat mop, a disc mop, a track-type cleaning mop, or other types of wet cleaning members. For example, the cleaning member 220 is a roller. In some embodiments, the cleaning assembly 200 is movably arranged on the support 100 in the vertical direction, and the cleaning assembly 200 can be raised and lowered relative to the support 100 in the vertical direction. In other embodiments, the cleaning assembly 200 is fixedly connected with the support 100 in the vertical direction, and the cleaning assembly 200 and the support 100 are synchronously raised and lowered in the vertical direction.

[0100] The outer periphery of the cleaning member 220 is provided with a mop for cleaning the floor. The mop can be detachably arranged on the outer periphery of the cleaning member 220 by adhesion, magnetic attraction, or other means, so as to facilitate the user to replace the mop later.

[0101] In addition to the housing 210 and the cleaning member 220, the cleaning assembly 200 can further include a squeegee (the squeegee is shown in Figure 16 , Figure 17 , Figure 23 , Figure 25 , Figure 27 The squeegee is arranged on one side of the cleaning member 220 and abuts against the cleaning member 220, and is used to scrape off the sewage on the cleaning member 220. Specifically, the squeegee scrapes off the sewage on the cleaning member 220, so that the cleaning member 220 can clean the surface to be cleaned in a clean state subsequently.

[0102] In an embodiment, the cleaning device further includes a sewage tank (the sewage tank is shown in Figure 16 、 Figure 17 、 Figure 23 、 Figure 25 、 Figures 27 to 29 It is shown that the sewage tank is arranged on the same side of the cleaning member 220 as the squeegee rib, and is used to collect the sewage on the cleaning member 220 scraped by the squeegee rib, that is, the sewage on the cleaning member 220 is scraped by the squeegee rib and then flows into the sewage tank along the squeegee rib, and the subsequent sewage in the sewage tank can be sucked into the sewage box under the action of the suction assembly.

[0103] It should be noted that in other embodiments, the sewage tank can also not be arranged, and the sewage on the cleaning member 220 is directly sucked into the sewage box after being pressed and scraped by the squeegee rib.

[0104] The shielding member 400 is movably arranged between the first position and the second position, when the shielding member 400 is located at the first position, the shielding member 400 is at least partially located below the cleaning member 220, and when the shielding member 400 is located at the second position, the shielding member 400 is separated from below the cleaning member 220, and at this time the shielding member 400 can be moved to other positions such as the side of the cleaning member 220, the upper side of the cleaning member 220, etc.

[0105] The driving mechanism 300 is connected with the shielding member 400, and is used to drive the shielding member 400 to move between the first position and the second position on the side of the cleaning member 220 away from the squeegee rib. It can be understood that the driving mechanism 300 is arranged to drive the shielding member 400 to move on the side of the cleaning member 220 away from the squeegee rib, which can avoid the interference between the shielding member 400 and the squeegee rib during the movement.

[0106] When the driving mechanism 300 drives the shielding member 400 to move from the second position to the first position, the shielding member 400 is located between the cleaning member 220 and the surface to be cleaned, which can avoid the contact between the cleaning member 220 and the surface to be cleaned, and realize the physical isolation between the cleaning member 220 and the surface to be cleaned, and when the driving mechanism 300 drives the shielding member 400 to move from the first position to the second position, the shielding member 400 is separated from between the cleaning member 220 and the surface to be cleaned, and then the cleaning member 220 can continue to clean the surface to be cleaned.

[0107] Through the above arrangement, when the cleaning assembly 200 does not need to contact the surface to be cleaned, the driving mechanism 300 can drive the shielding member 400 to move from the second position to the first position, which can avoid the pollution of the surface to be cleaned by the cleaning member 220 or the wetting of the surface to be cleaned (such as a blanket) by the water droplets on the cleaning member 220, and can realize the physical isolation between the surface to be cleaned and the cleaning assembly 200; when the cleaning assembly 200 needs to clean the surface to be cleaned, the driving mechanism 300 can drive the shielding member 400 to move from the first position to the second position to realize continuous cleaning, so that the arrangement of the present application can meet various needs of use.

[0108] In some embodiments, the cleaning device may further include structures such as a clean water pipe, a clean water box, a wastewater pipe, and a wastewater box. The clean water box supplies clean water to the cleaning component 220 through the clean water pipe, and the wastewater box collects wastewater from the wastewater tank or directly collects wastewater scraped off by the squeegee through the wastewater pipe.

[0109] In some embodiments, such as Figure 6 As shown, the shielding member 400 is disposed inside the receiving cavity formed by the housing 210. In some other embodiments, the shielding member 400 is disposed outside the receiving cavity formed by the housing 210, as described below.

[0110] In some embodiments, the drive mechanism 300 drives the shielding member 400 to move along a straight line to below the cleaning member 220; in other embodiments, the drive mechanism 300 drives the shielding member 400 to move along an arc to below the cleaning member 220. In summary, this application does not limit the movement trajectory of the shielding member 400.

[0111] In some embodiments, such as Figures 1-6 As shown, the drive mechanism 300 is mounted on the cleaning assembly 200, as... Figure 9 As shown, the housing 210 can be provided with multiple mounting holes 211. The cleaning component 200 is connected to the drive mechanism 300 through the mounting holes 211 on the housing 210 and threaded connectors passing through the mounting holes 211. The drive mechanism 300 can also be installed on the cleaning component 200 by adhesive, snap-fit, or other means. In some other embodiments, the drive mechanism 300 can also be installed on the bracket 100, as described below.

[0112] In some embodiments, such as Figures 1-6 As shown, the drive mechanism 300, in addition to driving the blocking member 400 to move, is also used to drive the cleaning component 200 to move vertically, and to drive the cleaning member 220 of the cleaning component 200 to rotate.

[0113] In some other embodiments, the drive mechanism 300 can only drive the cleaning component 200 to move vertically, in addition to driving the shield 400 to move. In this case, another drive mechanism is needed to drive the cleaning component 220 to rotate.

[0114] In some other embodiments, the drive mechanism 300 can only drive the blocking member 400 to move. In this case, it is necessary to drive the cleaning component 200 to move vertically and drive the cleaning member 220 to rotate simultaneously through one or two drive mechanisms. It should be noted that the vertical movement of the cleaning component 200 and the rotation of the cleaning member 220 can be driven by the same drive mechanism or by two drive mechanisms respectively.

[0115] In some embodiments, when the drive mechanism 300 moves the shielding member 400 to the first position, it simultaneously drives the cleaning component 200 to move upward; and when the drive mechanism 300 moves the shielding member 400 to the second position, it simultaneously drives the cleaning component 200 to move downward. In other embodiments, the drive mechanism 300 may first drive the cleaning component 200 to move upward, and then drive the shielding member 400 to move from the second position to the first position; or the drive mechanism 300 may first drive the shielding member 400 to move from the first position to the second position, and then drive the cleaning component 200 to move downward. That is, the rising of the cleaning component 200 and the moving of the shielding member 400 from the second position to the first position can be simultaneous or sequential, and the moving of the shielding member 400 from the first position to the second position and the lowering of the cleaning component 200 can be simultaneous or sequential.

[0116] In some other embodiments, when the drive mechanism 300 drives the shield 400 to move to the first position, it simultaneously drives the cleaning component 200 to move downward, and when the drive mechanism 300 drives the shield 400 to move to the second position, it simultaneously drives the cleaning component 200 to move upward.

[0117] like Figures 1-6 As shown, in some embodiments, since the drive mechanism 300 is mounted on the cleaning component 200, the drive mechanism 300 can move vertically together with the cleaning component 200 when driving the cleaning component 200 to move vertically.

[0118] like Figures 3-6 and Figure 11 As shown, the shielding member 400 can be a plate-like structure or an arc-shaped structure. The shielding member 400 can also be a concave structure, a V-shaped structure, or other shapes with grooves. The shape of the shielding member 400 can match the shape of the cleaning member 220.

[0119] In some embodiments, such as Figure 6 and Figure 11 As shown, the cleaning component 220 has a roller-like structure, and the shielding component 400 can be an arc-shaped structure, with the center of curvature of the shielding component 400 located on the side of the shielding component 400 facing the cleaning component 220. The driving mechanism 300 drives the shielding component 400 to rotate around the shielding component 400. The arc-shaped structure of the shielding component 400 allows it to catch water droplets dripping from the mop of the cleaning component 220 and prevents water droplets from sliding off the edge of the shielding component 400.

[0120] In actual execution, when the cleaning device is used to clean the floor, the driving mechanism 300 drives the cleaning assembly 200 to move vertically downwards until the mop on the periphery of the cleaning member 220 is tightly attached to the floor, in the process, the shielding member 400 moves to the second position, i.e. the shielding member 400 moves to a position away from below the cleaning assembly 200, for example, the shielding member 400 can move to above, side or other positions of the cleaning assembly 200, and the driving mechanism 300 drives the cleaning member 220 of the cleaning assembly 200 to rotate, at this time, the mop on the periphery of the cleaning member 220 is tightly attached to the floor, and the cleaning member 220 rotates under the driving of the driving mechanism 300, so that the rotation of the cleaning member 220 can be used to clean the floor.

[0121] When the cleaning device is used to clean the carpet, or the cleaning device returns to the base station after cleaning, or the cleaning device enters a pre-set area which does not need to be cleaned by the cleaning member 220, the driving mechanism 300 drives the cleaning assembly 200 to move vertically upwards, and at the same time, the driving mechanism 300 drives the shielding member 400 to move to below the cleaning assembly 200, when the cleaning assembly 200 rises to the highest point, the driving mechanism 300 stops driving the movement of the cleaning assembly 200, the shielding member 400 and the cleaning member 220, at this time, the cleaning member 220 is separated from the surface to be cleaned, and the shielding member 400 is placed between the cleaning member 220 and the floor, so that the physical isolation between the cleaning member 220 and the surface to be cleaned can be achieved.

[0122] In some embodiments, as shown in Figures 3-5 、 Figure 7 and Figure 8 , the driving mechanism 300 comprises a first output end 321; the first output end 321 is connected with the cleaning assembly 200 to drive the cleaning assembly 200 to move vertically, and / or the first output end 321 is connected with the shielding member 400.

[0123] The first output end 321 can be connected with the cleaning assembly 200, or the first output end 321 is connected with the shielding member 400, or the first output end 321 is connected with both the cleaning assembly 200 and the shielding member 400.

[0124] By setting the first output end 321 of the driving mechanism 300 to be connected with the cleaning assembly 200 and / or the shielding member 400, the application range of the driving mechanism 300 can be increased.

[0125] In some embodiments, the first output end 321 is connected with the cleaning assembly 200 to drive the cleaning assembly 200 to move vertically, and the first output end 321 is connected with the shielding member 400 to drive the shielding member 400 to move to the first position when the cleaning assembly 200 moves upwards.

[0126] As shown in Figures 3-5 、 Figure 7And Figure 8 As shown in FIG. 4, there is a gap between the shielding member 400 and the cleaning member 220. Since the first output end 321 of the driving mechanism 300 simultaneously drives the cleaning assembly 200 to move vertically and drives the shielding member 400 to move, when the driving mechanism 300 drives the cleaning assembly 200 to move vertically, the shielding member 400 moves vertically together with the cleaning assembly 200, i.e., the gap distance between the shielding member 400 and the cleaning member 220 is fixed.

[0127] By simultaneously connecting the first output end 321 with the cleaning assembly 200 and the shielding member 400, the number of devices can be reduced, the size of the cleaning device can be reduced, and the gap distance between the shielding member 400 and the cleaning member 220 can be kept constant, thereby reducing the probability that water droplets splashed when falling on the shielding member 400 when the distance between the cleaning assembly 200 and the shielding member 400 is too large at the first position, and further reducing the probability that the carpet is soaked by the mop on the cleaning member 220 and the cleaned floor is secondarily contaminated.

[0128] In some embodiments, the driving mechanism 300 further comprises a second output end 322, which is connected with the cleaning member 220 to drive the cleaning member 220 to rotate.

[0129] As shown in FIG. 4, the first output end 321 and the second output end 322 are configured to be able to rotate forward and reverse, and the rotation directions can be opposite or the same. Figures 3-5 、 Figure 7 And Figure 8 As shown in FIG. 4, the first output end 321 and the second output end 322 are configured to be able to rotate forward and reverse, and the rotation directions can be opposite or the same.

[0130] By the above-mentioned first output end 321 and the second output end 322, the movement of the shielding member 400, the cleaning assembly 200 and the shielding member 400 is simultaneously driven by one driving mechanism 300, which can reduce the number of devices, reduce the size of the cleaning device, and keep the gap distance between the shielding member 400 and the cleaning member 220 constant, thereby reducing the probability that water droplets splashed when falling on the shielding member 400 when the distance between the cleaning assembly 200 and the shielding member 400 is too large at the first position, and further reducing the probability that the carpet is soaked by the mop on the cleaning member 220 and the cleaned floor is secondarily contaminated.

[0131] In some embodiments, as shown in FIG. 4, the first output end 321 comprises a first output shaft 3211, a one-way bearing 3212 and a first output gear 3213, the first output gear 3213 is installed on the first output shaft 3211 through the one-way bearing 3212, and the first output gear 3213 is power-coupled with the bracket 100 and the shielding member 400. Figures 3-5 、 Figure 7 And Figure 8 In some embodiments, as shown in FIG. 4, the first output end 321 comprises a first output shaft 3211, a one-way bearing 3212 and a first output gear 3213, the first output gear 3213 is installed on the first output shaft 3211 through the one-way bearing 3212, and the first output gear 3213 is power-coupled with the bracket 100 and the shielding member 400.

[0132] As shown in FIG. 4, the first output end 321 and the second output end 322 are configured to be able to rotate forward and reverse, and the rotation directions can be opposite or the same. Figures 3-5 、 Figure 7 and Figure 8 As shown in

[0133] As shown in Figure 8 , the first output gear 3213 is connected with the outer ring of the one-way bearing 3212, and the first output shaft 3211 is connected with the inner ring of the one-way bearing 3212.

[0134] From the perspective of Figure 4 and Figure 5 , the counterclockwise rotation direction of the first output gear 3213 is the rotatable direction of the one-way bearing 3212, and the clockwise rotation direction of the first output gear 3213 is the non-rotatable direction of the one-way bearing 3212.

[0135] Since the first output gear 3213 is installed on the first output shaft 3211 through the one-way bearing 3212, when the first output shaft 3211 rotates in the rotatable direction of the one-way bearing 3212, the inner ring of the one-way bearing 3212 can rotate relative to the outer ring, and there is no power transmission between the first output shaft 3211 and the one-way bearing 3212; when the first output shaft 3211 rotates in the non-rotatable direction of the one-way bearing 3212, the inner ring and the outer ring of the one-way bearing 3212 cannot rotate, at this time the first output gear 3213 rotates together with the first output shaft 3211 in the same direction under the action of the one-way bearing 3212.

[0136] In actual execution, as shown in Figure 4 and Figure 5 , when the first output shaft 3211 rotates in the rotatable direction of the one-way bearing 3212, the first output gear 3213 cannot be driven to rotate together with the first output shaft 3211, under the action of the driving mechanism 300 and the gravity of the cleaning assembly 200 itself, the driving mechanism 300 and the cleaning assembly 200 move vertically downward on the support 100, at this time the first output gear 3213 rotates in the rotatable direction of the one-way bearing 3212 under the action of the friction or other force between the first output gear 3213 and the support 100, and drives the shielding piece 400 to move to the second position, when the cleaning assembly 200 moves to the lowest position, the cleaning assembly 200 cannot continue to move downward, at this time the first output gear 3213 stops rotating, the shielding piece 400 stops moving, and the driving mechanism 300 only drives the cleaning piece 220 to rotate, so that the cleaning piece 220 can be used to clean the ground.

[0137] As shown in Figure 4 and Figure 5As shown, when the first output shaft 3211 rotates in the direction in which the one-way bearing 3212 cannot rotate, the first output shaft 3211 drives the first output gear 3213 to rotate, at which time the first output gear 3213 moves upward along the vertical direction under the action of friction or other force between the first output gear 3213 and the support 100, and drives the cleaning assembly 200 and the driving mechanism 300 to move upward along the vertical direction as a whole, and meanwhile the first output gear 3213 drives the shielding member 400 to move to the first position.

[0138] By arranging the first output shaft 3211, the first output gear 3213 and the one-way bearing 3212, the vertical movement of the cleaning assembly 200 and the movement of the shielding member 400 can be simultaneously driven, the structure is simple, the integration of the cleaning device can be improved, the space occupied by the driving mechanism 300 can be reduced, and thus the overall volume of the cleaning device can be reduced, and the production cost can be reduced to a certain extent.

[0139] In some embodiments, as shown in Figure 4 , Figure 5 and Figure 12 , the support 100 is provided with a rack 500 extending along the vertical direction, and the first output gear 3213 is engaged with the rack 500.

[0140] As shown in Figure 4 , Figure 5 and Figure 12 , the support 100 is provided with a rack 500 extending along the vertical direction on the inner wall of one side of the support 100 in the width direction, and the first output gear 3213 is engaged with the rack 500, and during the transmission between the first output gear 3213 and the rack 500, the first output gear 3213 can move along the vertical direction on the rack 500.

[0141] In actual execution, as shown in Figure 4 , Figure 5 and Figure 12 , when the first output shaft 3211 rotates in the direction in which the one-way bearing 3212 can rotate, the first output gear 3213 cannot be driven to rotate by the first output shaft 3211, and under the action of the gravity of the driving mechanism 300 and the cleaning assembly 200, the driving mechanism 300 and the cleaning assembly 200 move downward along the vertical direction on the support 100, at which time the first output gear 3213 is driven to rotate by the rack 500, and drives the shielding member 400 to move to the first position, and when the cleaning assembly 200 moves to the lowest position, the cleaning assembly 200 cannot move downward any more, at which time the first output gear 3213 stops rotating, the shielding member 400 stops moving, and the driving mechanism 300 only drives the cleaning member 220 to rotate, so that the cleaning member 220 can be used to clean the ground.

[0142] As shown in Figure 4 , Figure 5and Figure 12 As shown, when the first output shaft 3211 rotates in the direction where the one-way bearing 3212 cannot rotate, the first output shaft 3211 drives the first output gear 3213 to rotate together. At this time, the first output gear 3213 cooperates with the rack 500 to drive and move vertically upward, thereby driving the cleaning component 200 and the drive mechanism 300 to move vertically upward as a whole. At the same time, the first output gear 3213 drives the shield 400 to move below the cleaning component 200.

[0143] Since the cleaning component 200, the drive mechanism 300, and the shield 400 move vertically together, and the gear and rack 500 meshing has a large load-bearing capacity, the cleaning component 200 can be driven to move vertically by the first output gear 3213 meshing with the rack 500. This can improve the stability of the cleaning component 200, the drive mechanism 300, and the shield 400 when they move vertically, and reduce the probability of power transmission failure due to insufficient load-bearing capacity.

[0144] In some embodiments, such as Figures 3-5 and Figure 11 As shown, the blocking member 400 is provided with a blocking member gear 430, and the first output gear 3213 meshes with the blocking member gear 430.

[0145] Among them, such as Figures 3-5 and Figure 11 As shown, the shielding member 400 is sleeved on the outer periphery of the cleaning member 220, and one end of the shielding member 400 is supported on the second output end 322, while the other end of the shielding member 400 is supported on the end of the cleaning member 220. That is, the shielding member 400 can rotate relative to the cleaning member 220 and the second output end 322.

[0146] like Figures 3-5 and Figure 11 As shown, a blocking gear 430 is provided on the outer periphery of one end of the blocking member 400 near the first output shaft 3211, and the blocking gear 430 meshes with the first output gear 3213.

[0147] In actual implementation, such as Figures 3-5 and Figure 11As shown, when the first output shaft 3211 rotates along the rotatable direction of the one-way bearing 3212, the first output gear 3213 cannot be driven to rotate by the first output shaft 3211, and under the gravity of the driving mechanism 300 and the cleaning assembly 200, the driving mechanism 300 and the cleaning assembly 200 move vertically downward on the support 100. At this time, the first output gear 3213 is in transmission with the rack 500, and the first output gear 3213 rotates. Since the first output gear 3213 is engaged with the shielding gear 430, the first output gear 3213 drives the shielding gear 430 to rotate, and further drives the shielding piece 400 to rotate, so as to rotate the shielding piece 400 to the side or above the cleaning assembly 200. When the cleaning assembly 200 moves to the lowest position, the cleaning assembly 200 cannot continue to move downward, at this time, the first output gear 3213 stops rotating, the shielding piece 400 stops moving, and the driving mechanism 300 only drives the cleaning piece 220 to rotate, so that the cleaning piece 220 can be used to clean the ground.

[0148] As shown in FIGS. 1 and 2, the driving mechanism 300 includes a first output end 321, a second output end 322, a third output end 323, a fourth output end 324, a first transmission mechanism 331, a second transmission mechanism 332, a third transmission mechanism 333, and a fourth transmission mechanism 334. Figures 3-5 and Figure 11 As shown, when the first output shaft 3211 rotates along the rotatable direction of the one-way bearing 3212, the first output gear 3213 cannot be driven to rotate by the first output shaft 3211, and under the gravity of the driving mechanism 300 and the cleaning assembly 200, the driving mechanism 300 and the cleaning assembly 200 move vertically downward on the support 100. At this time, the first output gear 3213 is in transmission with the rack 500, and the first output gear 3213 rotates. Since the first output gear 3213 is engaged with the shielding gear 430, the first output gear 3213 drives the shielding gear 430 to rotate, and further drives the shielding piece 400 to rotate, so as to rotate the shielding piece 400 to the side or above the cleaning assembly 200. When the cleaning assembly 200 moves to the lowest position, the cleaning assembly 200 cannot continue to move downward, at this time, the first output gear 3213 stops rotating, the shielding piece 400 stops moving, and the driving mechanism 300 only drives the cleaning piece 220 to rotate, so that the cleaning piece 220 can be used to clean the ground.

[0149] By driving the shielding piece 400 to rotate by the driving mechanism 300, the shielding piece 400 can be arranged between the housing 210 and the cleaning piece 220, so as to reduce the size of the space occupied by the shielding piece 400, and further reduce the volume of the cleaning device. Meanwhile, the first output gear 3213 and the shielding gear 430 are engaged to drive the shielding piece 400 to move, which is stable in transmission and can improve the stability of the shielding piece 400 during movement.

[0150] It should be noted that in other embodiments, the first output end 321 can only include the first output shaft 3211 and the first output gear 3213, and the first output gear 3213 is engaged with the shielding gear 430 arranged on the side of the shielding piece 400 away from the cleaning piece 220. With the rotation of the first output shaft 3211, the first output gear 3213 rotates synchronously, thereby driving the shielding piece 400 to rotate around the cleaning piece 220.

[0151] In some embodiments, in order to avoid the shielding gear 430 scratching the surface to be cleaned when the shielding member 400 is in the first position, the surface of the shielding member 400 away from the cleaning member 220 is provided with a groove, the shielding gear 430 is formed in the groove, and the groove opening is higher than the tooth top surface of the shielding gear 430. The specific description of the groove can be referred to below.

[0152] In some embodiments, as shown in Figures 3-5 and Figure 11 , the shielding member 400 comprises a shielding member body 410, a supporting structure 420, and a shielding gear 430.

[0153] As shown in Figures 3-5 and Figure 11 , the shielding member body 410 is used to move to the first position when the cleaning assembly 200 moves upward, the shielding member body 410 can be a concave structure, a V-shaped structure, or other structures with grooves, for example, the shielding member body 410 is a circular arc structure, and the center of curvature of the shielding member body 410 is located on the side of the shielding member 400 facing the cleaning member 220.

[0154] The supporting structure 420 is connected with the shielding member body 410, and the supporting structure 420 can be a supporting hole in a rectangular structure, a trapezoidal structure, or other shape structures, for example, as shown in Figures 3-5 and Figure 11 , the supporting structure 420 is a circular ring structure.

[0155] As shown in Figures 3-5 and Figure 11 , the two ends of the shielding member body 410 in the axial direction are connected with the supporting structure 420, the shielding member body 410 is supported on the second output end 322 and the cleaning member 220 through the supporting structure 420, and the supporting axis coincides with the rotation axis of the cleaning member 220, that is, the shielding member 400 and the cleaning member 220 rotate around the same axis.

[0156] The supporting structure 420 and the second output end 322 and the cleaning member 220 can be filled with lubricating oil, lubricating liquid, or other objects for lubrication to realize the relative rotation between the supporting structure 420 and the second output end 322 and the cleaning member 220.

[0157] As shown in Figures 3-5 and Figure 11 , the shielding gear 430 is installed on the supporting structure 420, and the shielding gear 430 can be installed on the supporting structure 420 supported on the second output end 322, or the shielding gear 430 can be installed on each supporting structure 420.

[0158] Through the arrangement of the shielding member body 410, the supporting structure 420 and the shielding member gear 430, the structure is simple, the rotation of the shielding member 400 can be facilitated, the supporting axis is arranged to coincide with the rotation axis of the cleaning member 220, and the probability of interference between the shielding member 400 and the cleaning member 220 during rotation can be reduced.

[0159] In some embodiments, as shown in Figures 3-5 and Figure 11 , the shielding member gear 430 is located on a part of the supporting structure 420 in the circumferential direction.

[0160] In some embodiments, as shown in Figures 3-5 and Figure 11 , a part of the outer periphery of the supporting structure 420 is provided with the shielding member gear 430, for example, one third of the supporting structure 420 in the circumferential direction is provided with the shielding member gear 430.

[0161] Since the shielding member 400 only needs to move to the first position when the cleaning assembly 200 moves upward, and move to the second position when the cleaning assembly 200 moves downward, the shielding member 400 can move back and forth within a certain angle in the circumferential direction, that is, the meshing teeth of the shielding member gear 430 are arranged on a part of the supporting structure 420 in the circumferential direction, the movement of the shielding member 400 in different directions within the required angle can be realized, the time for the shielding member 400 to move to the specified position can be shortened, the speed of switching the position of the shielding member 400 can be improved, and the production cost can be reduced to a certain extent.

[0162] In some embodiments, as shown in Figures 3-5 , Figure 7 and Figure 8 , the second output end 322 includes a second output shaft 3221 and a second output shaft sleeve 3222, the second output shaft sleeve 3222 is installed on the second output shaft 3221, and the second output shaft sleeve 3222 is power-coupled to the cleaning member 220.

[0163] In some embodiments, as shown in Figures 3-5 , Figure 7 and Figure 8 , the second output shaft sleeve 3222 is installed on one end of the second output shaft 3221 close to the cleaning member 220, the cleaning member 220 is provided with a fitting hole 221 close to the end of the second output shaft 3221, and the fitting hole 221 is inserted and matched with the second output shaft sleeve 3222.

[0164] In actual execution, when the driving mechanism 300 drives the cleaning member 220 to rotate, the driving mechanism 300 transmits power to the second output shaft 3221, the second output shaft 3221 transmits power to the second output shaft sleeve 3222, and the second output shaft sleeve 3222 drives the cleaning member 220 to rotate.

[0165] By adopting the second output shaft sleeve 3222 to be coupled with the cleaning member 220, the abrasion between the second output shaft 3221 and the cleaning member 220 can be reduced, and the position of the cleaning member 220 can be fixed.

[0166] In some embodiments, as shown in Figure 3 The shielding member 400 is supported on the second output shaft sleeve 3222.

[0167] In some embodiments, as shown in Figure 3 The supporting structure 420 of the shielding member 400 is supported on the second output shaft sleeve 3222, and lubricating oil, lubricating liquid or other objects for lubrication can be filled between the supporting structure 420 and the second output shaft sleeve 3222.

[0168] Since the supporting structure 420 of the shielding member 400 is provided with the shielding member gear 430, the supporting structure 420 has a relatively heavy weight, and therefore, the shielding member 400 is supported on the second output shaft sleeve 3222, the stability of the shielding member 400 can be improved, and the abrasion between the supporting structure 420 and the second output shaft 3221 can be reduced.

[0169] In some embodiments, as shown in Figure 7 and Figure 8 The second output shaft sleeve 3222 includes a first section 32221 and a second section 32222 connected with each other, the first section 32221 is coupled with the second output shaft 3221, the first section 32221 is a rotary body, and the shielding member 400 is supported on the first section 32221, the second section 32222 is a non-rotary body, and the second section 32222 is coupled with the cleaning member 220.

[0170] In some embodiments, as shown in Figure 7 and Figure 8 The second output shaft sleeve 3222 includes a first section 32221 and a second section 32222 connected with each other in sequence along the axial direction, the first section 32221 is installed on the second output shaft 3221, the second section 32222 is inserted and matched with the assembly hole 221 of the cleaning member 220, and the supporting structure 420 of the shielding member 400 is supported on the first section 32221.

[0171] The first section 32221 can be a rotary body with a conical structure, a spherical structure, a circular truncated cone structure or other shape structures, for example, as shown in Figure 7 and Figure 8 The first section 32221 is a cylindrical structure; the second section 32222 can be a non-rotary body with a pyramid structure, a prism structure or other shape structures, for example, as shown in Figure 7 and Figure 8 The second section 32222 is a rectangular structure.

[0172] By setting the first section 32221 as a rotary body, rotation of the shielding piece 400 relative to the first section 32221 can be achieved, reducing the probability that the second output shaft sleeve 3222 causes the shielding piece 400 to rotate incorrectly when transmitting power to the shielding piece 400. By setting the second section 32222 as a non-rotary body, power transmission from the second output shaft sleeve 3222 to the cleaning piece 220 can be achieved, reducing the probability that slippage between the second output shaft sleeve 3222 and the cleaning piece 220 results in low power transmission efficiency.

[0173] In some embodiments, as shown in Figures 1-3 、 Figure 7 and Figure 8 , the driving mechanism 300 includes a driving motor 310 and a speed reducer 320.

[0174] As shown in Figures 1-3 、 Figure 7 and Figure 8 , the input end of the speed reducer 320 is power-coupled to the output end of the driving motor 310, and the speed reducer 320 has a first output end 321 and a second output end 322, i.e., the speed reducer 320 is provided with a first output shaft 3211 and a second output shaft 3221.

[0175] In actual execution, when the driving mechanism 300 drives the cleaning assembly 200 and the shielding piece 400 to move, the driving motor 310 transmits power to the speed reducer 320, which transmits power to the first output shaft 3211 and the second output shaft 3221 after deceleration, and finally drives the cleaning assembly 200 and the shielding piece 400 to move through the power of the first output shaft 3211 and the second output shaft 3221.

[0176] By the above arrangement of the driving motor 310 and the speed reducer 320, one driving motor 310 can be used to achieve the functions of driving the cleaning assembly 200 to move vertically, driving the shielding piece 400 to move, and driving the cleaning piece 220 to rotate, which is simple in structure and can further reduce the overall size of the cleaning device and production costs.

[0177] In other embodiments, two driving motors 310 can also be provided, one of which is used to achieve two of the functions of driving the cleaning assembly 200 to move vertically, driving the shielding piece 400 to move, and driving the cleaning piece 220 to rotate, and the other is used to achieve the other function.

[0178] In yet other embodiments, three driving motors 310 can also be provided, each of which is used to achieve the functions of driving the cleaning assembly 200 to move vertically, driving the shielding piece 400 to move, and driving the cleaning piece 220 to rotate.

[0179] In some embodiments, as shown in Figures 1-6 and Figure 9 The cleaning assembly 200 is provided with a guide hole 212, and the support 100 is provided with a guide column 110, the guide hole 212 is inserted into the guide column 110 and is in vertical sliding fit.

[0180] As shown in Figures 1-6 and Figure 9 The cleaning member 220 and the shielding member 400 are arranged in the accommodating cavity formed by the shell 210, and the shielding member 400 is arranged on the periphery of the cleaning member 220, and the shell 210 of the cleaning assembly 200 is provided with a guide hole 212 extending in the vertical direction, the support 100 is provided with a guide column 110 extending in the vertical direction, the guide hole 212 on the shell 210 is inserted into the guide column 110, and the cleaning assembly 200 can slide in the vertical direction on the guide column 110 through the guide hole 212.

[0181] Through the arrangement of the guide hole 212 and the guide column 110, the vertical movement of the cleaning assembly 200 on the support 100 can be realized, and the structure is simple, and the assembly difficulty and the production cost can be reduced.

[0182] In some embodiments, as shown in Figure 1 The cleaning device further comprises a detection device 600 and a controller.

[0183] The detection device 600 is used for collecting position information of the shielding member 400, and the detection device 600 can be a mechanical switch, which is contacted by the shielding member 400 when the shielding member 400 is rotated to a specified position, and at this time, the position information of the shielding member 400 is collected by the mechanical switch.

[0184] As shown in Figure 1 The detection device 600 can also be an optical coupling sensor, an infrared sensor, a mechanical sensor or other types of position detection sensors, and the detection device 600 can be installed above the support 100, and the position information of the shielding member 400 is collected by the sensor in a non-contact manner.

[0185] The controller is electrically connected with the detection device 600, and is used for controlling the working state of the driving mechanism 300 according to the position information collected by the detection device 600.

[0186] In some embodiments, when the driving mechanism 300 can only drive the shielding member 400 to move, when the detection device 600 collects the position information of the shielding member 400 as being located below the cleaning assembly 200, i.e. in the first position, a signal is sent to the controller, and then when the controller receives a trigger signal for controlling the movement of the shielding member 400, the controller determines, according to the signal sent by the detection device 600, that the shielding member 400 is located below the cleaning assembly 200, and thus the controller controls the driving mechanism 300 to drive the shielding member 400 to move away from below the cleaning assembly 200; when the detection device 600 collects the position information of the shielding member 400 as being in the second position, a signal is sent to the controller, and then when the controller receives a trigger signal for controlling the movement of the shielding member 400, the controller determines, according to the signal sent by the detection device 600, that the shielding member 400 is not located below the cleaning assembly 200, and thus the controller controls the driving mechanism 300 to drive the shielding member 400 to move to below the cleaning member 220. At this time, the controller controls the driving mechanism 300 to drive the shielding member 400 to move from the first position to the second position or from the second position to the first position according to the position of the shielding member 400 collected by the detection device 600.

[0187] In some other embodiments, when the driving mechanism 300 can drive both the shielding member 400 to move and the cleaning assembly 200 to move vertically, when the driving mechanism 300 drives the cleaning assembly 200 to move vertically upward to the first position, the shielding member 400 moves to below the cleaning assembly 200, at this time the detection device 600 collects the position information of the shielding member 400 as being located below the cleaning assembly 200, and sends a signal to the controller, and the controller controls the driving mechanism 300 to stop. At this time, the driving mechanism 300 can be controlled to stop when the driving mechanism 300 drives the shielding member 400 to move to below the cleaning assembly 200, so that the shielding member 400 can be kept at the position below the cleaning assembly 200, and the accuracy of the movement of the shielding member 400 to the specified position is improved.

[0188] In some embodiments, as shown in Figure 4 and Figure 5 The cleaning device has a first working mode, and in the first working mode, the cleaning assembly 200 rises along the vertical direction and the shielding member 400 is located below the cleaning member 220.

[0189] In some embodiments, as shown in Figure 4 and Figure 5As shown, in the first working mode, the cleaning equipment can be in the state of cleaning carpet, returning to base station, or single cleaning. At this time, the drive mechanism 300 drives the cleaning component 200 to move vertically upward and drives the blocking component 400 to move to a position below the cleaning component 200. When the cleaning component 200 moves vertically upward to the highest point, the blocking component 400 is located below the cleaning component 200. At the same time, the detection device 600 collects the position information of the blocking component 400 as being located below the cleaning component 200 and sends a signal to the controller. The controller controls the drive mechanism 300 to stop. At this time, the cleaning component 200 stops moving vertically, and the cleaning component 220 and the blocking component 400 stop rotating.

[0190] By setting the first working mode as described above, the cleaning equipment can raise the mop when cleaning carpets, returning to the base station, or in single cleaning mode, reducing the probability of the mop wetting the carpet or causing secondary pollution to the already cleaned floor, expanding the scope of application of the cleaning equipment, and improving the user experience.

[0191] In some embodiments, such as Figure 6 As shown, the cleaning equipment has a second working mode. In the second working mode, the cleaning component 200 descends to contact the surface to be cleaned, the cleaning part 220 rotates, and the shielding part 400 moves to a second position, which is different from the position below the cleaning part 220.

[0192] The second position can be the side, top, or other position of the cleaning component 220.

[0193] like Figure 6 As shown, in the second working mode, the cleaning device can be in the state of cleaning the floor. At this time, the drive mechanism 300 drives the first output shaft 3211 to rotate in the direction in which the one-way bearing 3212 can rotate. The first output gear 3213 cannot be driven to rotate together by the first output shaft 3211. Under the gravity of the drive mechanism 300 and the cleaning component 200, the drive mechanism 300 and the cleaning component 200 move vertically downward on the bracket 100. At this time, the first output gear 3213 cooperates with the rack 500 for transmission. The first output gear 3213 rotates and drives the blocking member 400 to move to a position away from the bottom of the cleaning component 200. When the cleaning component 200 moves downward to the lowest point, the cleaning component 200 can no longer move downward. At this time, the first output gear 3213 stops rotating, the blocking member 400 stops moving, and the drive mechanism 300 only drives the cleaning component 220 to rotate, so that the cleaning component 220 can be used to clean the floor.

[0194] By setting the second working mode as described above, the cleaning unit 220 can be used to clean the ground when the cleaning equipment is located on the ground that needs to be cleaned, thus completing the cleaning task.

[0195] In some embodiments, the cleaning device further comprises a sensor and a controller.

[0196] The sensor is configured to detect at least one of material information of the surface to be cleaned, an area where the surface to be cleaned is located, a cleaning degree of the surface to be cleaned, and a stain type on the surface to be cleaned. The controller is electrically connected with the sensor and the driving mechanism, and is configured to control a working state of the driving mechanism or a working mode of the cleaning device according to the information detected by the sensor.

[0197] In an application scenario, when the sensor detects that the material of the surface to be cleaned is the material of a floor or other parts that need to be cleaned, the sensor sends a signal to the controller, and the controller controls the driving mechanism 300 to drive the cleaning assembly 200 to descend to the lowest point, drive the cleaning member 220 to rotate, and drive the shielding member 400 to move to the second position, or controls the cleaning device to be in the second working mode. When the sensor detects that the material of the surface to be cleaned is the material of a carpet, in order to avoid the water on the cleaning member 220 from wetting the carpet, the sensor sends a signal to the controller, and the controller controls the driving mechanism 300 to drive the cleaning assembly 200 to ascend to the highest point, drive the cleaning member 220 to stop rotating, and drive the shielding member 400 to move to the first position, or controls the cleaning device to be in the first working mode.

[0198] In another application scenario, the user can also specify a target area that does not need to be cleaned by the cleaning member 220 in advance. When the sensor detects that the cleaning device enters the target area, the controller is triggered to control the driving mechanism 300 to drive the cleaning assembly 200 to ascend to the highest point, and control the shielding member 400 to move from the second position to the first position, so as to realize physical isolation between the cleaning assembly 200 and the surface to be cleaned. When the sensor detects that the cleaning device leaves the target area, the controller controls the driving mechanism 300 to drive the shielding member 400 to move from the first position to the second position, and drive the cleaning assembly 200 to descend to be in contact with the surface to be cleaned, and the cleaning member 220 rotates, so that the cleaning member 220 continues to clean the surface to be cleaned.

[0199] In yet another application scenario, when the sensor detects that the cleaning degree of the surface to be cleaned is very clean, in order to avoid the cleaning member 220 from polluting the surface to be cleaned, the controller is triggered to control the driving mechanism 300 to drive the cleaning assembly 200 to ascend to the highest point, and control the shielding member 400 to move from the second position to the first position, so as to realize physical isolation between the cleaning assembly 200 and the surface to be cleaned. When the sensor detects that the cleaning degree of the surface to be cleaned reaches a dirty degree that needs to be cleaned by the cleaning member 220, the controller controls the driving mechanism 300 to drive the shielding member 400 to move from the first position to the second position, and drive the cleaning assembly 200 to descend to be in contact with the surface to be cleaned, and the cleaning member 220 rotates, so that the cleaning member 220 continues to clean the surface to be cleaned.

[0200] In another application scenario, when the cleaning member 220 is a dry cleaning member, for example, a rolling brush member, when the sensor detects that the stain on the surface to be cleaned is a wet stain, in order to avoid the wet stain from wetting the rolling brush member and affecting the subsequent cleaning of dust by the rolling brush member, the controller controls the driving mechanism 300 to drive the cleaning assembly 200 to rise to the highest point, and controls the shielding member 400 to move from the second position to the first position, realizing the physical isolation between the cleaning assembly 200 and the surface to be cleaned. When the sensor detects that the stain on the surface to be cleaned is a dry stain, the controller controls the driving mechanism 300 to drive the shielding member 400 to move from the first position to the second position, and drives the cleaning assembly 200 to descend to be in contact with the surface to be cleaned, and the cleaning member 220 rotates, so that the cleaning member 220 continues to clean the surface to be cleaned.

[0201] Referring to Figures 13 to 17 The same as the above-mentioned embodiments is that the driving mechanism 300 drives the shielding member 400 to move between the first position and the second position on the side of the cleaning member 220 away from the squeegee 232. In this embodiment, the cleaning device further comprises a sewage tank 231, and the sewage on the cleaning member 220 is scraped down by the squeegee 232 and flows into the sewage tank 231 along the squeegee 232. As described above, in other embodiments, the sewage tank 231 can also not be provided, and the sewage on the cleaning member 220 is directly sucked into the sewage box after being scraped down by the squeegee 232.

[0202] In an embodiment, referring to Figure 16 and Figure 17 In an embodiment, the squeegee 232 is partially arranged in the sewage tank 231 and partially extends out of the sewage tank 231 to abut against the cleaning member 220, so as to ensure that the sewage flows smoothly into the sewage tank 231.

[0203] In an embodiment, considering that the squeegee 232 needs to abut against the cleaning member 220 and press the sewage on the cleaning member 220, a material with high strength is used to prepare the squeegee 232, and the sewage tank 231 can be prepared by using a common material such as plastic. In this embodiment, the sewage tank 231 and the squeegee 232 can be arranged as two independent structures, which are independent of each other. At the same time, this arrangement can also facilitate the disassembly of the squeegee 232 and the sewage tank 231, and facilitate the cleaning of the two.

[0204] In other embodiments, the sewage tank 231 can also be integrally formed with the squeegee 232.

[0205] Referring to Figure 16 and Figure 17As same as the above embodiments, the cleaning member 220 is in a drum shape, the shielding member 400 is in a circular arc shape, the center of curvature of the shielding member 400 is located on the side of the shielding member 400 facing the cleaning member 220, and the driving mechanism 300 drives the shielding member 400 to rotate around the cleaning member 220. As shown in Figure 16 , when the shielding member 400 is in the first position, the shielding member 400 wraps the bottom of the cleaning member 220 exposed from the containing cavity, as shown in Figure 17 , when the shielding member 400 is in the second position, the bottom of the cleaning member 220 is exposed from the containing cavity.

[0206] Referring to Figure 14 and Figure 15 , different from the above embodiments, at this time, the first output end 321 of the driving mechanism 300 only drives the shielding member 400 to move, and does not drive the cleaning assembly 200 to move vertically or the cleaning member 220 to rotate. Figures 1 to 12 Continuing to refer to

[0207] and Figure 14 , the first output end 321 includes a first output shaft 3211 and a first output gear 3213, the first output gear 3213 is sleeved on the first output shaft 3211, the first output gear 3213 is engaged with the shielding member gear 430 on the side of the shielding member 400 away from the cleaning member 220, so that the first output shaft 3211 drives the first output gear 3213 to rotate, and with the rotation of the first output gear 3213, the shielding member 400 moves between the first position and the second position. Specifically, assuming that when the first output shaft 3211 drives the first output gear 3213 to rotate in a first rotation direction, the shielding member 400 moves from the first position to the second position, then when the first output shaft 3211 drives the first output gear 3213 to rotate in a second rotation direction opposite to the first rotation direction, the shielding member 400 moves from the second position to the first position. Figure 15 Referring to

[0208] , in some embodiments, the outer circumferential surface of the shielding member 400 is provided with a groove 411, the shielding member gear 430 is arranged in the groove 411, and the groove opening of the groove 411 is higher than the tooth top surface of the shielding member gear 430. This arrangement can avoid scratching the surface to be cleaned when the shielding member gear 430 protrudes when the shielding member 400 is in the first position. Of course, in other embodiments, the groove 411 can also not be provided. Figure 18 Referring to

[0209] , in some embodiments, the outer circumferential surface of the shielding member 400 is provided with a groove 411, the shielding member gear 430 is arranged in the groove 411, and the groove opening of the groove 411 is higher than the tooth top surface of the shielding member gear 430. This arrangement can avoid scratching the surface to be cleaned when the shielding member gear 430 protrudes when the shielding member 400 is in the first position. Of course, in other embodiments, the groove 411 can also not be provided. Figures 14 to 18In order to increase the rotation range of the shielding member 400, the shielding member 400 comprises a shielding member body 410 in a circular arc structure and a transmission arm 440 in a circular arc structure, the center of curvature of the shielding member body 410 is located on the side of the shielding member body 410 facing the cleaning member 220, and the shielding member gear 430 is formed on the surface of the shielding member body 410 away from the cleaning member 220 and extends along the circumference of the shielding member body 410. The transmission arm 440 is connected with the shielding member body 410, and the center of curvature of the transmission arm 440 coincides with the center of curvature of the shielding member body 410, that is, the transmission arm 440 and the shielding member body 410 rotate around the same rotation axis, and the shielding member gear 430 further extends from the shielding member body 410 to the transmission arm 440. It should be noted that in other embodiments, the shielding member 400 can also not comprise the transmission arm 440, and at this time the shielding member gear 430 is only formed on the shielding member body 410.

[0210] Referring to Figures 14 to 18 In an embodiment, the recess 411 is formed on the shielding member body 410 and the transmission arm 440, and the shielding member gear 430 is formed on the recess 411, so as to avoid scratching the surface to be cleaned when the shielding member 400 is in the first position.

[0211] Continuing to refer to Figure 18 In an embodiment, in order to ensure the overall strength of the shielding member 400, the shielding member body 410 and the transmission arm 440 are integrally formed.

[0212] Referring to Figure 14 and Figure 15 In some embodiments, the number of shielding member gears 430 is one, and the shielding member gear 430 is arranged at the middle position in the axial direction of the shielding member 400. This arrangement can keep the shielding member 400 balanced and ensure stable rotation of the shielding member 400. In this embodiment, when the shielding member 400 comprises the shielding member body 410 and the transmission arm 440, the number of transmission arms 440 is one, and the transmission arm 440 is connected with the middle position in the axial direction of the shielding member body 410.

[0213] Of course, in other embodiments, the shielding member gear 430 can also be arranged at the end position in the axial direction of the shielding member 400.

[0214] Referring to Figure 15 , Figure 16 and Figure 17 In some embodiments, the housing 210 and the support 100 are fixedly connected, and the support 100 and the cleaning assembly 200 are synchronously raised and lowered along the vertical direction. However, in other embodiments, the housing 210 and the support 100 can also be movably connected in the vertical direction.

[0215] Referring to Figure 13 、 Figure 14 and Figure 15 In some embodiments, the driving mechanism 300 is fixedly installed on the support 100, and the driving mechanism 300 is synchronously raised and lowered with the support 100 in the vertical direction.

[0216] In some embodiments, referring to Figure 16 and Figure 17 the support 100 comprises a plurality of connecting plates 120, and the plurality of connecting plates 120 surround to form a containing space, and the cleaning assembly 200 is arranged in the containing space. In some embodiments, the shell 210 can be fixedly connected with one of the connecting plates 120. In some embodiments, the shell 210 can be integrally formed with one of the connecting plates 120.

[0217] Continuing to refer to Figure 14 and Figure 15 In some embodiments, the shielding member 400 is arranged outside the containing cavity formed by the shell 210 and is supported by the shell 210. In some other embodiments, the shielding member 400 can also be arranged inside the containing cavity formed by the shell 210, and in this case, the shielding member 400 can be supported by the supporting structure protruding from the side wall of the support 100.

[0218] In the embodiments of Figures 13 to 18 the driving mechanism 300 only drives the shielding member 400 to rotate. However, another driving mechanism 300 can also be arranged to drive the cleaning assembly 200 to move in the vertical direction and drive the cleaning member 220 to rotate, or two driving mechanisms 300 can be arranged, one of which drives the cleaning assembly 200 to move in the vertical direction, and the other drives the cleaning member 220 to rotate.

[0219] It should be noted that in the embodiments of Figures 13 to 18 the driving mechanism 300 only drives the shielding member 400 to rotate, but improvements can be made on the embodiments of Figures 13 to 18 to further arrange the driving mechanism 300 to comprise a second output end 322, and the second output end 322 is connected with the cleaning member 220 to drive the cleaning member 220 to rotate. For example, referring to the embodiments of Figure 3 , the driving mechanism 300 comprises a second output shaft 3221 and a second output shaft sleeve 3222 in addition to the first output shaft 3211 and the first output gear 3213, the second output shaft sleeve 3222 is installed on the second output shaft 3221, and the second output shaft sleeve 3221 is connected with the cleaning member 220. The specific connection relationship between the second output shaft sleeve 3221 and the cleaning member 220 can be referred to the above description, and will not be repeated here.

[0220] In addition, Figures 13 to 18 An improvement is made to the previous embodiment by providing a shielding member 400 supported on the second output shaft sleeve 3221. The specific connection relationship between the shielding member 400 and the second output shaft sleeve 3221 can be found above and will not be repeated here.

[0221] In addition Figures 13 to 18 In this embodiment, the drive mechanism 300 may include only the drive motor 310, excluding the reducer 320. In this case, the output shaft of the drive motor 310 directly serves as the first output shaft 3211. However, it can also be referred to... Figures 1 to 12 The embodiments, for Figures 13 to 18 The embodiment is improved by setting the drive mechanism 300 to include a drive motor 310 and a reducer 320. Similarly, the input end of the reducer 320 is also connected to the output end of the drive motor 310 by power coupling. The reducer 320 has a first output end 321 and a second output end 322. That is, the reducer 320 is provided with a first output shaft 3211 and a second output shaft 3221. The first output gear 3213 sleeved on the first output shaft 3211 drives the shield 400 to rotate, and the second output shaft sleeve 3222 installed on the second output shaft 3221 drives the cleaning component 220 to rotate.

[0222] See Figures 19 to 26 ,and Figures 13 to 18 The difference in this embodiment is that there are multiple blocking gears 430, which are spaced apart axially on the blocking body 410; the drive mechanism 300 further includes a transmission gear 330 and a transmission shaft 340.

[0223] There are multiple transmission gears 330, and each of the multiple transmission gears 330 is arranged in a one-to-one correspondence with a multiple shielding gear 430. The corresponding transmission gears 330 and shielding gears 430 mesh with each other. One of the multiple transmission gears 330 meshes with the first output gear 3213. The transmission shaft 340 is arranged along the axial direction of the shielding body 410 and connects the multiple transmission gears 330.

[0224] Specifically, in this embodiment, as the first output shaft 3211 rotates, the transmission gear 330 directly meshing with the first output gear 3213 rotates. Since multiple transmission gears 330 are connected through the transmission shaft 340, as the transmission gear 330 directly meshing with the first output gear 3213 rotates, the other transmission gears 330 also rotate. Simultaneously, because the multiple transmission gears 330 interact with multiple blocking gears 430, they ultimately drive the blocking body 410 to rotate. The number of transmission gears 330 can be two, three, or more, and is not limited here. It is understood that the number of transmission gears 330 is equal to the number of blocking gears 430.

[0225] Referring to Figure 22 In an embodiment, the number of the shield gears 430 is two, and the two shield gears 430 are arranged at two axial ends of the shield body 410 respectively.

[0226] Referring to Figures 19 to 22 In some embodiments, the driving mechanism 300 further comprises a cam 350, which is sleeved on the transmission shaft 340, and the cam 350 is limited in a limiting space formed by the base 11 of the machine body and the limiting member 12. At this time, the shell 210 is arranged in the accommodation space formed by the bracket 100, and the bracket 100 and the shell 210 are fixedly connected. The cleaning member 220 and the shield 400 are arranged in the accommodation cavity formed by the shell 210, and the shield 400 is arranged on the circumferential side of the cleaning member 220. At the same time, gaps 101 are formed between the two ends of the shell 210 in the axial direction and the bracket 100. The shield gears 430 on the shield 400 are exposed from the gaps 101. The side of the shell 210 away from the cleaning member 220 is connected with a connecting assembly 213, and the transmission shaft 340 penetrates through the connecting assembly 213.

[0227] Specifically, the limiting member 12 has a U-shaped structure, which is fixedly connected with the base 11 and cooperatively forms a limiting space. The cam 350 is always in the limiting space. With the rotation of the cam 350, the transmission shaft 340 moves up and down along the vertical direction. Since the transmission shaft 340 penetrates through the connecting assembly 213 connected with the shell 210, the transmission shaft 340 can drive the shell 210 to move in the vertical direction. Under the driving of the shell 210, the bracket 100 moves up and down along the vertical direction, and all the structures in the bracket 100 move synchronously up and down along the vertical direction.

[0228] Referring to Figure 20 In an embodiment, the transmission shaft 340 is sleeved with a shaft sleeve 341. The connecting assembly 213 can comprise a shaft sleeve bracket 2131 and a shaft sleeve fixing member 2132. The shaft sleeve fixing member 2132 is connected with the shaft sleeve bracket 2131, and a rotating space is formed between the shaft sleeve fixing member 2132 and the shaft sleeve bracket 2131. The shaft sleeve 341 is limited in the rotating space. Specifically, the shaft sleeve 341 is in direct contact with the transmission shaft 340. The shaft sleeve 341 can be made of wear-resistant and self-lubricating materials to ensure the stable rotation of the transmission shaft 340. In an embodiment, the shaft sleeve bracket 2131 is integrally formed with the shell 210.

[0229] Referring to Figure 20 In some embodiments, the driving motor 310 and the transmission shaft 340 are arranged on the same side of the shell 210, and the driving motor 310 is mounted on the shell 210. Figure 20 In some embodiments, the output shaft of the driving motor 310 directly serves as the first output shaft 3211.

[0230] Referring to Figure 20 and Figure 21 In some embodiments, the shield 400 is supported by the support structure 102 provided on the opposite two side walls of the bracket 100 which are spaced in the axial direction of the cleaning member 220. In some embodiments, in order to avoid interference between the cleaning member 220 and the shield 400, there is a gap in the radial direction between the cleaning member 220 and the shield 400.

[0231] Referring to Figure 22 In some embodiments, in order to ensure that the transmission shaft 340 is in force balance, the cam 350 is sleeved at the middle position of the transmission shaft 340, that is, the distance from the cam 350 to the two ends of the transmission shaft 340 is equal.

[0232] Referring to Figure 23 and Figure 24 When the cam 350 rotates to the position where the small end is above the large end, the transmission shaft 340 rises vertically to the highest point, that is, at this time the cleaning assembly 200 rises vertically to the highest point; referring to Figure 25 and Figure 26 When the cam 350 rotates to the position where the large end is above the small end, the transmission shaft 340 descends vertically to the lowest point, that is, at this time the cleaning assembly 200 descends vertically to the lowest point.

[0233] Referring to Figure 23 and Figure 24 In an embodiment, as the first output shaft 3211 rotates, when the transmission shaft 340 drives the cleaning assembly 200 to rise vertically to the highest point, the shield 400 moves to the first position; referring to Figure 25 and Figure 26 When the transmission shaft 340 drives the cleaning assembly 200 to descend vertically to the lowest point, the shield 400 moves to the second position.

[0234] Referring to Figures 19 to 21 In order to ensure that the cleaning assembly 200 runs stably in the vertical direction relative to the base 11, the top of the cleaning assembly 200 is further provided with a buffer column 214 which penetrates the base 11 and is movably connected with the base 11, and the elastic member 215 is sleeved on the buffer column 214 and elastically supports between the cleaning assembly 200 and the base 11. When the transmission shaft 340 drives the cleaning assembly 200 to rise vertically to the highest point, the buffer column 214 moves towards the base 11, and the elastic member 215 is compressed, and when the transmission shaft 340 drives the cleaning assembly 200 to descend vertically to the lowest point, the buffer column 214 moves away from the base 11, and the elastic member 215 is elongated. The elastic member 215 can be a spring or the like structure, and the structure of the elastic member 215 is not limited in the present application.

[0235] In Figures 19 to 26In some embodiments, the driving mechanism 300 is configured to drive the movement of the shielding member 400 and the vertical movement of the cleaning assembly 200.
