Technical field

[0005] The present application belongs to the technical field of cleaning tools, and in particular relates to a cleaning device and a cleaning system. [Background Technology]

[0006] With the iterative updates and development of technology, cleaning equipment has entered the lives of ordinary families and has gradually become popular. As the cleaning equipment moves on the ground, its integrated cleaning parts come into contact with and rub against the surface to be cleaned, thereby achieving cleaning.

[0007] Currently, when it is not necessary for the cleaning device's cleaning components to come into contact with the surface being cleaned, the common approach is to control the robot to avoid the area where the surface is being cleaned, or to control the robot to lift the cleaning components. Controlling the robot to avoid the area where the surface is being cleaned can easily disrupt the cleaning schedule of the cleaning device, while controlling the robot to lift the cleaning components does not fully achieve physical isolation between the surface being cleaned and the cleaning components. Therefore, current practices need to be improved. [Summary of the invention]

[0142] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0143] The following describes a cleaning device and a cleaning apparatus according to an embodiment of the present application with reference to Figures 1 to 38.

[0144] 1 to 6 , the cleaning device includes a body (not shown in the drawings), a bracket 100, a cleaning assembly 200, a drive mechanism 300, and a shielding member 400. The cleaning device of the present application is used to operate on a surface to be cleaned and clean the surface to be cleaned.

[0145] The bracket 100 is used to movably mount the cleaning assembly 200 on the bottom of the cleaning device body. 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 assembly 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 assembly 200 to move vertically.

[0146] It should be noted that the vertical direction mentioned in this application refers to the height direction of the cleaning equipment.

[0147] In one embodiment, the bracket 100 is surrounded to form an accommodating space, and the cleaning assembly 200 , the driving mechanism 300 , and the shielding member 400 are at least partially disposed in the accommodating space.

[0148] As shown in Figures 1-6, the cleaning assembly 200 includes a housing 210 and a first cleaning member 220. The housing 210 is disposed within and connected to the bracket 100. The bracket 100 has a receiving cavity, and the first cleaning member 220 is rotatably disposed within the receiving cavity. In one embodiment, the housing 210 can be a semi-cylindrical structure with a cavity at the bottom of the housing 210. The first cleaning member 220 is mounted below the housing 210 and located within the cavity of the housing 210.

[0149] As shown in Figures 1-6, in some embodiments, the housing 210 is movably connected to the bracket 100. Specifically, the housing 210 is movably mounted on the bracket 100 in the vertical direction, allowing the housing 210 to be vertically raised and lowered relative to the bracket 100. In other embodiments, the housing 210 is fixedly connected to the bracket 100, allowing the housing 210 and the bracket 100 to be vertically raised and lowered synchronously, as described below.

[0150] The first cleaning member 220 may include but is not limited to a dry cleaning member and a wet cleaning member. The dry cleaning member may include a roller brush or other types of dry cleaning members, and the wet cleaning member may include a flat mop, a disc mop, a crawler cleaning mop or other types of wet cleaning members. In one embodiment, the rotating axis of the first cleaning member 220 is parallel to the surface to be cleaned. For example, the first cleaning member 220 is a roller.

[0151] In some embodiments, the cleaning assembly 200 is movably mounted on the bracket 100 in the vertical direction, and the cleaning assembly 200 can rise and fall vertically relative to the bracket 100. In other embodiments, the cleaning assembly 200 is fixedly connected to the bracket 100 in the vertical direction, and the cleaning assembly 200 and the bracket 100 rise and fall synchronously in the vertical direction.

[0152] A mop is provided on the periphery of the first cleaning member 220 for cleaning the surface to be cleaned. The mop can be detachably mounted on the periphery of the first cleaning member 220 by bonding, magnetism or other means, so that the user can replace the mop later.

[0153] In addition to the housing 210 and the first cleaning member 220, the cleaning assembly 200 may also include a wiper rib (the wiper rib is shown in Figures 16, 17, 23, 25, and 36, and the wiper rib is labeled 232 in the figures). The wiper rib is provided on one side of the first cleaning member 220, and the wiper rib abuts against the first cleaning member 220 to scrape off the dirty water on the first cleaning member 220. Specifically, the wiper rib scrapes off the dirty water on the first cleaning member 220, so that the first cleaning member 220 can subsequently clean the surface to be cleaned in a clean state. It should be noted that in other embodiments, the wiper rib may not be provided.

[0154] In one embodiment, the cleaning device further includes a sewage trough (the sewage trough is shown in Figures 16, 17, 23, 25, 36 to 38, and the sewage trough in the figure is labeled 231). The sewage trough and the wiper rib are arranged on the same side of the first cleaning member 220, and are used to collect the sewage scraped off the first cleaning member 220 by the wiper rib. That is, the sewage on the first cleaning member 220 is scraped off by the wiper rib and flows into the sewage trough along the wiper rib. Subsequently, the sewage in the sewage trough can be sucked into the sewage box under the action of the suction component.

[0155] It should be noted that, in other embodiments, the sewage tank may not be provided. In this case, after the scraping ribs squeeze and scrape the sewage off the first cleaning member 220 , the sewage is directly sucked into the sewage box.

[0156] The shielding member 400 is movably installed between a first position and a second position. When the shielding member 400 is located at the first position, the shielding member 400 is at least partially located below the first cleaning member 220; when the shielding member 400 is located at the second position, the shielding member 400 is pulled out from under the first cleaning member 220. At this time, the shielding member 400 can move to other positions such as the side and above the first cleaning member 220.

[0157] The drive mechanism 300 is connected to the shielding member 400 and is configured to drive the shielding member 400 to move between a first position and a second position. When the cleaning assembly 200 further includes a wiper bar, the drive mechanism 300 can be configured to drive the shielding member 400 to move between the first position and the second position on the side of the first cleaning member 220 facing away from the wiper bar. It will be appreciated that configuring the drive mechanism 300 to drive the shielding member 400 to move on the side of the first cleaning member 220 facing away from the wiper bar can prevent the shielding member 400 from interfering with the wiper bar during movement.

[0158] 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 first cleaning member 220 and the surface to be cleaned, which can avoid contact between the first cleaning member 220 and the surface to be cleaned, and realize physical isolation between the first cleaning member 220 and the surface to be cleaned. 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 pulled out from between the first cleaning member 220 and the surface to be cleaned, and then the first cleaning member 220 can continue to clean the surface to be cleaned.

[0159] Through the above-mentioned setting, when the cleaning component 200 is not needed 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 prevent the first cleaning member 220 from contaminating the surface to be cleaned or prevent water droplets on the first cleaning member 220 from falling and wetting the surface to be cleaned (such as a blanket), and can achieve physical isolation between the surface to be cleaned and the cleaning component 200; when the cleaning component 200 is needed 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 continue cleaning. Therefore, the setting of the present application can meet various usage needs.

[0160] In addition, in some embodiments, the cleaning device may further include a clean water pipe, a clean water box, a sewage pipe, a sewage box, etc. The clean water box provides clean water to the first cleaning member 220 through the clean water pipe, and the sewage box collects sewage from the sewage tank through the sewage pipe or directly collects sewage scraped by the scraping ribs.

[0161] 6 , the shielding member 400 is disposed inside the accommodating cavity formed by the housing 210. In other embodiments, the shielding member 400 is disposed outside the accommodating cavity formed by the housing 210, as described below.

[0162] In some embodiments, the driving mechanism 300 drives the shielding member 400 to move along a straight line to below the first cleaning member 220. In other embodiments, the driving mechanism 300 drives the shielding member 400 to move along an arc to below the first cleaning member 220. In short, the present application does not limit the movement trajectory of the shielding member 400.

[0163] In some embodiments, as shown in Figures 1 to 6, the drive mechanism 300 is mounted on the cleaning assembly 200. As shown in Figure 9, a plurality of mounting holes 211 may be provided on the housing 210. The cleaning assembly 200 is connected to the drive mechanism 300 via the mounting holes 211 on the housing 210 and threaded connectors passing through the mounting holes 211. The drive mechanism 300 may also be mounted to the cleaning assembly 200 by bonding, snap fasteners, or other means. In other embodiments, the drive mechanism 300 may also be mounted on the bracket 100, as described below.

[0164] In some embodiments, as shown in FIG. 1-6 , in addition to driving the shielding member 400 to move, the driving mechanism 300 is also used to drive the cleaning assembly 200 to move vertically and to drive the first cleaning member 220 of the cleaning assembly 200 to rotate.

[0165] In other embodiments, the driving mechanism 300 can only drive the cleaning assembly 200 to rise or fall vertically in addition to driving the shielding member 400 to move. In this case, another driving mechanism is required to drive the first cleaning member 220 to rotate.

[0166] In some other embodiments, the driving mechanism 300 can only drive the shielding member 400 to move. In this case, one or two driving mechanisms are required to simultaneously drive the cleaning component 200 to move vertically and drive the first cleaning member 220 to rotate. It should be noted that at this time, driving the cleaning component 200 to move vertically and driving the first cleaning member 220 to rotate can be driven by the same driving mechanism or by two driving mechanisms respectively.

[0167] In some embodiments, when the driving mechanism 300 drives the shielding member 400 to move to the first position, it simultaneously drives the cleaning assembly 200 upward, and when the driving mechanism 300 drives the shielding member 400 to move to the second position, it simultaneously drives the cleaning assembly 200 downward. In other embodiments, the driving mechanism 300 may first drive the cleaning assembly 200 upward and then drive the shielding member 400 from the second position to the first position, or the driving mechanism 300 may first drive the shielding member 400 from the first position to the second position and then drive the cleaning assembly 200 downward. In other words, the ascending of the cleaning assembly 200 and the movement of the shielding member 400 from the second position to the first position may occur simultaneously or sequentially, and the movement of the shielding member 400 from the first position to the second position and the descending of the cleaning assembly 200 may occur simultaneously or sequentially.

[0168] In some other embodiments, the driving mechanism 300 drives the cleaning assembly 200 downward when driving the shielding member 400 to move to the first position, and drives the cleaning assembly 200 upward when driving the shielding member 400 to move to the second position.

[0169] As shown in FIG. 1 to FIG. 6 , in some embodiments, since the driving mechanism 300 is installed on the cleaning assembly 200 , when the driving mechanism 300 drives the cleaning assembly 200 to move vertically, the driving mechanism 300 can move vertically together with the cleaning assembly 200 .

[0170] As shown in Figures 3-6 and 11, the shielding member 400 can be a plate-shaped structure or an arc-shaped structure. The shielding member 400 can 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 first cleaning member 220.

[0171] In some embodiments, as shown in Figures 6 and 11, the first cleaning member 220 is a roller-shaped structure, the shielding member 400 is an arc-shaped structure, and the center of curvature of the shielding member 400 is located on the side of the shielding member 400 facing the first cleaning member 220. The driving mechanism 300 drives the shielding member 400 to rotate around the shielding member 400. The shielding member 400 is an arc-shaped structure, which enables the shielding member 400 to catch water droplets dripping from the mop of the first cleaning member 220 and prevent the water droplets from sliding off the edge of the shielding member 400.

[0172] During the actual implementation process, when the cleaning equipment is used to clean the surface to be cleaned, the driving mechanism 300 drives the cleaning component 200 to move vertically downward until the first cleaning member 220 is close to the surface to be cleaned. During this process, the covering member 400 moves to the second position, that is, the covering member 400 moves to a position away from the bottom of the cleaning component 200. For example, the covering member 400 can move to the top, side or other position of the cleaning component 200, and the driving mechanism 300 drives the first cleaning member 220 of the cleaning component 200 to rotate. At this time, the outer periphery of the first cleaning member 220 is close to the surface to be cleaned, and the first cleaning member 220 rotates under the drive of the driving mechanism 300, so that the rotation of the first cleaning member 220 can be used to clean the surface to be cleaned.

[0173] 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 that does not need to be cleaned by the first cleaning member 220, the driving mechanism 300 drives the cleaning component 200 to move vertically upward, and at the same time, the driving mechanism 300 drives the shielding member 400 to move to the bottom of the cleaning component 200. When the cleaning component 200 rises to the highest point, the driving mechanism 300 stops driving the movement of the cleaning component 200, the shielding member 400 and the first cleaning member 220. At this time, the first cleaning member 220 is separated from the surface to be cleaned, and the shielding member 400 is placed between the first cleaning member 220 and the surface to be cleaned, thereby achieving physical isolation between the first cleaning member 220 and the surface to be cleaned.

[0174] In some embodiments, as shown in Figures 3-5, 7 and 8, the driving mechanism 300 includes a first output end 321; the first output end 321 is connected to the cleaning assembly 200 to drive the cleaning assembly 200 to move vertically, and / or, the first output end 321 is connected to the shielding member 400.

[0175] The first output end 321 may be connected to the cleaning assembly 200 , or the first output end 321 may be connected to the shielding member 400 , or the first output end 321 may be connected to both the cleaning assembly 200 and the shielding member 400 .

[0176] By arranging the first output end 321 of the driving mechanism 300 to be connected to the cleaning assembly 200 and / or the shielding member 400 , the applicable range of the driving mechanism 300 can be increased.

[0177] In some embodiments, the first output end 321 is connected to the cleaning assembly 200 to drive the cleaning assembly 200 to move vertically, and the first output end 321 is connected to the shielding member 400 to drive the shielding member 400 to move to the first position when driving the cleaning assembly 200 to move upward.

[0178] As shown in Figures 3-5, 7 and 8, there is a gap between the shielding member 400 and the first cleaning member 220. Since the first output end 321 of the driving mechanism 300 simultaneously drives the cleaning component 200 to move vertically and drives the shielding member 400 to move, when the driving mechanism 300 drives the cleaning component 200 to move vertically, the shielding member 400 moves vertically together with the cleaning component 200, that is, the gap distance between the shielding member 400 and the first cleaning member 220 is fixed.

[0179] By connecting the first output end 321 to the cleaning component 200 and the shielding member 400 at the same time, the number of devices can be reduced, the volume of the cleaning equipment can be reduced, and at the same time, a certain distance can always be maintained between the shielding member 400 and the first cleaning member 220, thereby reducing the probability of splashing when water droplets fall on the shielding member 400 due to the distance between the cleaning component 200 and the shielding member 400 being too large when in the first position, further reducing the probability of the carpet being soaked by the mop on the first cleaning member 220 and the cleaned floor being contaminated again.

[0180] In some embodiments, the driving mechanism 300 further includes a second output end 322 , and the second output end 322 is connected to the first cleaning member 220 to drive the first cleaning member 220 to rotate.

[0181] 3 to 5 , 7 and 8 , the first output end 321 and the second output end 322 are both configured to be capable of forward and reverse rotation, and the rotation directions can be opposite or the same.

[0182] By setting up the above-mentioned first output end 321 and second output end 322, a driving mechanism 300 is used to simultaneously drive the movement of the shielding member 400, the cleaning component 200 and the shielding member 400, thereby reducing the number of devices and the volume of the cleaning equipment. At the same time, a certain distance can be always maintained between the shielding member 400 and the first cleaning member 220, thereby reducing the probability of splashing when water droplets fall on the shielding member 400 due to the distance between the cleaning component 200 and the shielding member 400 being too large when in the first position, and further reducing the probability of the carpet being soaked by the mop on the first cleaning member 220 and the cleaned floor being contaminated again.

[0183] In some embodiments, as shown in Figures 3-5, 7 and 8, the first output end 321 includes: 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. The first output gear 3213 is dynamically coupled to the bracket 100 and the shielding member 400.

[0184] 3-5, 7 and 8, the first output gear 3213 and the bracket 100 can be connected by power coupling through meshing of a gear set, direct contact without meshing or other methods, and the first output gear 3213 and the shielding member 400 can also be connected by power coupling through meshing of a gear set, meshing of the gear rack 500 or other methods.

[0185] As shown in FIG. 8 , the first output gear 3213 is connected to the outer ring of the one-way bearing 3212 , and the first output shaft 3211 is connected to the inner ring of the one-way bearing 3212 .

[0186] 4 and 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 .

[0187] 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 along 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 no power is transmitted between the first output shaft 3211 and the one-way bearing 3212; when the first output shaft 3211 rotates along 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.

[0188] During the actual implementation process, as shown in Figures 4 and 5, 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 together by the first output shaft 3211. Under the action of the gravity of the driving mechanism 300 and the cleaning component 200 themselves, the driving mechanism 300 and the cleaning component 200 move vertically downward on the bracket 100. At this time, the first output gear 3213 rotates along the rotatable direction of the one-way bearing 3212 under the action of the friction between the bracket 100 or other forces, and drives the shielding member 400 to move to the second position. When the cleaning component 200 moves downward to the lowest point, the cleaning component 200 cannot continue to move downward. At this time, the first output gear 3213 stops rotating, the shielding member 400 stops moving, and the driving mechanism 300 only drives the first cleaning member 220 to rotate, so that the first cleaning member 220 can be used to clean the floor.

[0189] As shown in Figures 4 and 5, 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 together. At this time, the first output gear 3213 moves vertically upward under the action of friction or other forces between it and the bracket 100, and drives the cleaning component 200 and the driving mechanism 300 to move vertically upward as a whole. At the same time, the first output gear 3213 drives the shielding member 400 to move to the first position.

[0190] Through the arrangement of the above-mentioned first output shaft 3211, the first output gear 3213 and the one-way bearing 3212, the cleaning component 200 can be driven to move vertically and the shielding member 400 can be driven to move simultaneously. The structure is simple, which can improve the integration of the cleaning equipment, reduce the space occupied by the driving mechanism 300, and thus reduce the overall volume of the cleaning equipment, and at the same time reduce the production cost to a certain extent.

[0191] In some embodiments, as shown in FIG. 4 , FIG. 5 and FIG. 12 , the bracket 100 is provided with a rack 500 extending vertically, and the first output gear 3213 is engaged with the rack 500 .

[0192] As shown in Figures 4, 5 and 12, a rack 500 extending vertically is provided on the inner wall of one side of the bracket 100 in the width direction, and the first output gear 3213 is engaged with the rack 500. During the transmission process between the first output gear 3213 and the rack 500, the first output gear 3213 can move vertically on the rack 500.

[0193] During the actual implementation process, as shown in Figures 4, 5 and 12, 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 by the first output shaft 3211 to rotate together. Under the action of the gravity of the driving mechanism 300 and the cleaning component 200 themselves, the driving 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, and the first output gear 3213 rotates and drives the covering member 400 to move to the first position. When the cleaning component 200 moves downward to the lowest point, the cleaning component 200 cannot continue to move downward. At this time, the first output gear 3213 stops rotating, the covering member 400 stops moving, and the driving mechanism 300 only drives the first cleaning member 220 to rotate, so that the first cleaning member 220 can be used to clean the floor.

[0194] As shown in Figures 4, 5 and 12, 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 together. At this time, the first output gear 3213 cooperates with the rack 500 for transmission and moves vertically upward, thereby driving the cleaning component 200 and the driving mechanism 300 to move vertically upward as a whole. At the same time, the first output gear 3213 drives the shielding member 400 to move to the bottom of the cleaning component 200.

[0195] Since the cleaning component 200, the driving mechanism 300 and the shielding member 400 move vertically together, and the meshing of the gear rack 500 has a large load-bearing capacity, the cleaning component 200 is driven to move vertically by meshing the first output gear 3213 with the rack 500. This can improve the stability of the cleaning component 200, the driving mechanism 300 and the shielding member 400 when they move vertically, and reduce the probability of failure of power transmission due to insufficient load-bearing capacity.

[0196] In some embodiments, as shown in FIG. 3 to FIG. 5 and FIG. 11 , the shielding member 400 is provided with a shielding member gear 430 , and the first output gear 3213 is engaged with the shielding member gear 430 .

[0197] As shown in Figures 3-5 and 11, the shielding member 400 is sleeved on the outer periphery of the first cleaning member 220, and one end of the shielding member 400 is supported on the second output end 322, and the other end of the shielding member 400 is supported on the end of the first cleaning member 220, that is, the shielding member 400 can rotate relative to the first cleaning member 220 and the second output end 322.

[0198] As shown in FIG3-FIG5 and FIG11 , a shielding member gear 430 is provided on the outer periphery of one end of the shielding member 400 close to the first output shaft 3211 , and the shielding member gear 430 is externally meshed with the first output gear 3213 .

[0199] In the actual implementation process, as shown in Figures 3-5 and 11, 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 by the first output shaft 3211 to rotate together. Under the action of the gravity of the driving mechanism 300 and the cleaning component 200 themselves, the driving 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, and the first output gear 3213 rotates. 3213 is engaged with the shielding member gear 430, so the first output gear 3213 drives the shielding member gear 430 to rotate, and then drives the shielding member 400 to rotate, so that the shielding member 400 rotates to the side or top of the cleaning component 200. When the cleaning component 200 moves downward to the lowest point, the cleaning component 200 cannot continue to move downward. At this time, the first output gear 3213 stops rotating, the shielding member 400 stops moving, and the driving mechanism 300 only drives the first cleaning member 220 to rotate, so that the first cleaning member 220 can be used to clean the floor.

[0200] As shown in Figures 3-5 and 11, 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 together. At this time, the first output gear 3213 cooperates with the rack 500 for transmission and moves vertically upward, thereby driving the cleaning assembly 200 and the driving mechanism 300 to move vertically upward as a whole. At the same time, the first output gear 3213 drives the shielding member gear 430 to rotate, and then drives the shielding member 400 to rotate, so that the shielding member 400 rotates to the first position.

[0201] By utilizing the driving mechanism 300 to drive the shielding member 400 to rotate, the shielding member 400 can be disposed between the outer shell 210 and the first cleaning member 220, thereby reducing the size of the space occupied by the shielding member 400 and further reducing the volume of the cleaning equipment. At the same time, the shielding member 400 is driven to move by engaging with the first output gear 3213 and the shielding member gear 430, and the transmission is stable, which can improve the stability of the shielding member 400 during movement.

[0202] It should be noted that, in other embodiments, the first output end 321 may only include a first output shaft 3211 and a first output gear 3213. The first output gear 3213 engages with a shielding member gear 430 provided on the side of the shielding member 400 away from the first cleaning member 220. As the first output shaft 3211 rotates, the first output gear 3213 rotates synchronously, thereby driving the shielding member 400 to rotate around the first cleaning member 220.

[0203] In some embodiments, to prevent the shielding gear 430 from protruding and scratching the surface to be cleaned when the shielding member 400 is in the first position, a groove is provided on the surface of the shielding member 400 facing away from the first cleaning member 220. The shielding gear 430 is formed in the groove, and the notch of the groove is higher than the tooth top surface of the shielding gear 430. A detailed description of the groove is provided below.

[0204] In some embodiments, as shown in FIG. 3-FIG . 5 and FIG. 11 , the shutter 400 includes a shutter body 410 , a support structure 420 , and a shutter gear 430 .

[0205] As shown in Figures 3-5 and 11, the shielding member body 410 is used to move to the first position when the cleaning component 200 moves upward. The shielding member body 410 can be a concave structure, a V-shaped structure or other shape structure with a groove. For example, the shielding member body 410 is an arc-shaped structure, and the center of curvature of the shielding member body 410 is located on the side of the shielding member 400 facing the first cleaning member 220.

[0206] The support structure 420 is connected to the shielding member body 410. The support structure 420 may be a rectangular structure, a trapezoidal structure or other shaped structures with support holes. For example, as shown in FIG. 3-FIG . 5 and FIG. 11 , the support structure 420 is a circular ring structure.

[0207] As shown in Figures 3-5 and 11, the shielding member body 410 is connected to a supporting structure 420 at both ends along the axial direction. The shielding member body 410 is supported on the second output end 322 and the first cleaning member 220 respectively through the supporting structure 420, and the supporting axis coincides with the rotation axis of the first cleaning member 220, that is, the shielding member 400 and the first cleaning member 220 rotate around the same axis.

[0208] Lubricating oil, lubricating liquid or other lubricating substances may be injected between the support structure 420 , the second output end 322 and the first cleaning member 220 to achieve relative rotation among the support structure 420 , the second output end 322 and the first cleaning member 220 .

[0209] As shown in FIG3-FIG5 and FIG11 , the shielding gear 430 is mounted on the support structure 420 . The shielding gear 430 may be mounted on the support structure 420 supported on the second output end 322 , or may be mounted on each support structure 420 .

[0210] Through the arrangement of the above-mentioned shielding member body 410, supporting structure 420 and shielding member gear 430, the structure is simple, which can facilitate the rotation of the shielding member 400. At the same time, the supporting axis is set to coincide with the rotation axis of the first cleaning member 220, which can reduce the probability of the shielding member 400 interfering with the first cleaning member 220 during rotation.

[0211] In some embodiments, as shown in FIG. 3-FIG . 5 and FIG. 11 , the shutter gear 430 is located on a portion of the circumference of the support structure 420 .

[0212] As shown in FIG3-FIG5 and FIG11 , a shielding member gear 430 is installed on a portion of the outer periphery of the support structure 420 . For example, a shielding member gear 430 is installed on one-third of the circumference of the support structure 420 .

[0213] Since the shielding member 400 only needs to move to the first position when the cleaning component 200 moves upward, and move to the second position when the cleaning component 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 set to be located at a part of the circumference of the support structure 420, which can realize the movement of the shielding member 400 in different directions within the required angle, and at the same time can shorten the time for the shielding member 400 to move to the specified position, increase the speed of switching the shielding member 400, and reduce the production cost to a certain extent.

[0214] In some embodiments, as shown in Figures 3-5, 7 and 8, the second output end 322 includes: a second output shaft 3221 and a second output sleeve 3222, the second output sleeve 3222 is installed on the second output shaft 3221, and the second output sleeve 3222 is dynamically coupled to the first cleaning member 220.

[0215] 3-5, 7 and 8, the second output sleeve 3222 is installed on one end of the second output shaft 3221 close to the first cleaning member 220, and the end of the first cleaning member 220 close to the second output shaft 3221 is provided with an assembly hole 221, and the assembly hole 221 is plugged into the second output sleeve 3222.

[0216] During actual implementation, when the driving mechanism 300 drives the first 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 first cleaning member 220 to rotate.

[0217] By adopting the second output shaft sleeve 3222 to be connected to the first cleaning member 220 by power coupling, the wear between the second output shaft 3221 and the first cleaning member 220 can be reduced, and the position of the first cleaning member 220 can be easily fixed.

[0218] In some embodiments, as shown in FIG. 3 , the shielding member 400 is supported on the second output shaft sleeve 3222 .

[0219] As shown in FIG. 3 , the support structure 420 of the shielding member 400 is supported on the second output shaft sleeve 3222 , and lubricating oil, lubricating liquid or other lubricating objects can be poured between the support structure 420 and the second output shaft sleeve 3222 .

[0220] Since the shielding member gear 430 is provided on the supporting structure 420, the overall weight of the supporting structure 420 of the shielding member 400 is heavier. Therefore, supporting the shielding member 400 on the second output shaft sleeve 3222 can improve the stability of the support of the shielding member 400 and reduce the wear between the supporting structure 420 and the second output shaft 3221.

[0221] In some embodiments, as shown in Figures 7 and 8, the second output sleeve 3222 includes a first section 32221 and a second section 32222 connected to each other, the first section 32221 is dynamically coupled to the second output shaft 3221, the first section 32221 is a rotating body, and the shielding member 400 is supported on the first section 32221, the second section 32222 is a non-rotating body, and the second section 32222 is dynamically coupled to the first cleaning member 220.

[0222] As shown in Figures 7 and 8, the second output sleeve 3222 includes a first section 32221 and a second section 32222 connected in sequence along the axial direction. The first section 32221 is installed on the second output shaft 3221, the second section 32222 is plugged into the assembly hole 221 of the first cleaning member 220, and the supporting structure 420 of the shielding member 400 is supported on the first section 32221.

[0223] The first section 32221 can be a rotating body of a conical structure, a spherical structure, a truncated cone structure or other shaped structures. For example, as shown in Figures 7 and 8, the first section 32221 is a cylindrical structure; the second section 32222 can be a pyramidal structure, a prismatic structure or other shaped structures. Non-rotating body, for example, as shown in Figures 7 and 8, the second section 32222 is a rectangular structure.

[0224] By setting the first section 32221 as a rotating body, the shielding member 400 can be rotated relative to the first section 32221, reducing the probability that the second output sleeve 3222 transmits power to the shielding member 400, causing the shielding member 400 to rotate incorrectly; by setting the second section 32222 as a non-rotating body, the second output sleeve 3222 can transmit power to the first cleaning member 220, reducing the probability that slipping occurs between the second output sleeve 3222 and the first cleaning member 220, resulting in low power transmission efficiency.

[0225] In some embodiments, as shown in FIG. 1-FIG . 3 , FIG. 7 , and FIG. 8 , the driving mechanism 300 includes a driving motor 310 and a reducer 320 .

[0226] 1-3, 7 and 8, the input end of the reducer 320 is dynamically coupled to the output end of the drive motor 310, and the reducer 320 has a first output end 321 and a second output end 322, that is, a first output shaft 3211 and a second output shaft 3221 are provided in the reducer 320.

[0227] During the actual implementation process, when the driving mechanism 300 drives the cleaning component 200 and the shielding member 400 to move, the driving motor 310 transmits power to the reducer 320, and the reducer 320 transmits power to the first output shaft 3211 and the second output shaft 3221 after deceleration, and finally drives the cleaning component 200 and the shielding member 400 to move through the power of the first output shaft 3211 and the second output shaft 3221.

[0228] Through the arrangement of the above-mentioned drive motor 310 and the reducer 320, one drive motor 310 can be used to realize three functions: driving the cleaning component 200 to move vertically, driving the shielding member 400 to move, and driving the first cleaning member 220 to rotate. The structure is simple, which can further reduce the overall volume of the cleaning equipment and reduce production costs.

[0229] In other embodiments, two drive motors 310 may also be provided, wherein one drive motor 310 is used to realize two functions of driving the cleaning component 200 to move vertically, driving the shielding member 400 to move, and driving the first cleaning member 220 to rotate, and the other drive motor 310 is used to realize the other function of driving the cleaning component 200 to move vertically, driving the shielding member 400 to move, and driving the first cleaning member 220 to rotate.

[0230] In some other embodiments, three drive motors 310 may be provided. The three drive motors 310 are respectively used to drive the cleaning assembly 200 to move vertically, drive the shielding member 400 to move, and drive the first cleaning member 220 to rotate.

[0231] In some embodiments, as shown in FIG. 1-FIG . 6 and FIG. 9 , the cleaning assembly 200 is provided with a guide hole 212 , and the bracket 100 is provided with a guide post 110 . The guide hole 212 is plugged into the guide post 110 and slides in cooperation in the vertical direction.

[0232] As shown in Figures 1 to 6 and 9, the first cleaning member 220 and the shielding member 400 are both arranged in the accommodating cavity formed by the shell 210, and the shielding member 400 is arranged on the peripheral side of the first cleaning member 220. At the same time, the shell 210 of the cleaning component 200 is provided with a guide hole 212 extending vertically, and the bracket 100 is provided with a guide column 110 extending vertically. The guide hole 212 on the shell 210 is inserted into the guide column 110, and the cleaning component 200 can slide vertically on the guide column 110 through the guide hole 212.

[0233] By providing the guide holes 212 and the guide posts 110 , the cleaning assembly 200 can be moved vertically on the bracket 100 , and the structure is simple, which can reduce assembly difficulty and production costs.

[0234] In some embodiments, as shown in FIG1 , the cleaning device further includes a detection device 600 and a controller.

[0235] The detection device 600 is used to collect position information of the shielding member 400 . The detection device 600 may be a mechanical switch. When the shielding member 400 rotates to a specified position, it contacts the mechanical switch. At this time, the mechanical switch collects the position information of the shielding member 400 .

[0236] As shown in FIG1 , the detection device 600 may also be an optical coupling sensor, an infrared sensor, a mechanical sensor or other types of position detection sensors. The detection device 600 may be installed above the bracket 100 to realize contactless collection of the position information of the shielding member 400 through the sensor.

[0237] The controller is electrically connected to the detection device 600 and is used to control the working state of the driving mechanism 300 according to the position information collected by the detection device 600 .

[0238] 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 component 200, that is, in the first position, a signal is sent to the controller, and then when the controller receives a trigger signal to control the movement of the shielding member 400, the controller determines that the shielding member 400 is located below the cleaning component 200 based on the signal sent by the detection device 600, so the controller controls the driving mechanism 300 to drive the shielding member 400 to be withdrawn from under the cleaning component 200; when the detection device 600 collects that the shielding member 400 is located in the second position, a signal is sent to the controller, and then when the controller receives a trigger signal to control the movement of the shielding member 400, the controller determines that the shielding member 400 is not located below the cleaning component 200 at this time based on the signal sent by the detection device 600, so the controller controls the driving mechanism 300 to drive the shielding member 400 to move to below the first 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.

[0239] In 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 below the cleaning assembly 200. At this time, the detection device 600 collects the position information of the shielding member 400 as being below the cleaning assembly 200, sends a signal to the controller, and the controller controls the driving mechanism 300 to stop. In this case, when the driving mechanism 300 drives the shielding member 400 to move below the cleaning assembly 200, the driving mechanism 300 can be controlled to stop, so that the shielding member 400 can be maintained in the position below the cleaning assembly 200, thereby improving the accuracy of the shielding member 400 moving to the specified position.

[0240] In some embodiments, as shown in FIG. 4 and FIG. 5 , the cleaning device has a first working mode. In the first working mode, the cleaning assembly 200 rises vertically, and the shielding member 400 is located below the first cleaning member 220 .

[0241] 4 and 5 , in the first working mode, the cleaning device can be in the carpet cleaning, returning to the base station or single cleaning state. At this time, the driving mechanism 300 drives the cleaning component 200 to move vertically upward, and drives the shielding member 400 to move to the position below the cleaning component 200. When the cleaning component 200 moves vertically upward to the highest point, the shielding member 400 is located below the cleaning component 200. At the same time, the detection device 600 collects the position information of the shielding member 400 as being located below the cleaning component 200, and sends a signal to the controller. The controller controls the driving mechanism 300 to stop. At this time, the cleaning component 200 stops moving vertically, and the first cleaning member 220 and the shielding member 400 stop rotating.

[0242] By setting the above-mentioned first working mode, the cleaning device can lift the mop when cleaning the carpet, returning to the base station or in the single cleaning state, reducing the probability of the mop soaking the carpet or causing secondary pollution to the cleaned floor, expanding the scope of application of the cleaning device and improving the user experience.

[0243] In some embodiments, as shown in Figure 6, the cleaning device has a second working mode. When the cleaning device is in the second working mode, the cleaning component 200 descends to contact the surface to be cleaned, the first cleaning member 220 rotates, and the covering member 400 moves to the second position, which is different from the position below the first cleaning member 220.

[0244] The second position may be the side, top or other position of the first cleaning member 220 .

[0245] As shown in Figure 6, in the second working mode, the cleaning device can be in a state of cleaning the floor. At this time, the driving mechanism 300 drives the first output shaft 3211 to rotate along the rotatable direction of the one-way bearing 3212, and the first output gear 3213 cannot be driven to rotate together by the first output shaft 3211. Under the action of the gravity of the driving mechanism 300 and the cleaning component 200 themselves, the driving 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, and the first output gear 3213 rotates and drives the shielding 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 cannot continue to move downward. At this time, the first output gear 3213 stops rotating, the shielding member 400 stops moving, and the driving mechanism 300 only drives the first cleaning member 220 to rotate, so that the first cleaning member 220 can be used to clean the floor.

[0246] By setting the second working mode, when the cleaning device is located on the floor to be cleaned, the first cleaning member 220 can be used to clean the floor, thereby completing the task of cleaning the floor.

[0247] In some embodiments, the cleaning device further includes a sensor and a controller.

[0248] Among them, the sensor is used to detect at least one of the material information of the surface to be cleaned, the area where the surface to be cleaned is located, the cleanliness level of the surface to be cleaned, and the type of stains on the surface to be cleaned. The controller is electrically connected to the sensor and the driving mechanism, and is used to control the working state of the driving mechanism or the working mode of the cleaning equipment according to the information detected by the sensor.

[0249] In one application scenario, when the sensor detects that the material of the surface to be cleaned is the floor or other material that needs to be cleaned, it sends a signal to the controller, and the controller controls the driving mechanism 300 to drive the cleaning component 200 to descend to the lowest point, drive the first cleaning member 220 to rotate, and drive the shielding member 400 to move to the second position, or the controller 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 prevent the sewage on the first cleaning member 220 from dripping and wetting the carpet, the sensor sends a signal to the controller, and the controller controls the driving mechanism 300 to drive the cleaning component 200 to rise to the highest point, drive the first cleaning member 220 to stop rotating, and drive the shielding member 400 to move to the first position, or the controller controls the cleaning device to be in the first working mode.

[0250] In another application scenario, the user may pre-specify a target area that does not need to be cleaned by the first cleaning member 220. When the sensor detects that the cleaning device has entered the target area, the controller is triggered to control the drive mechanism 300 to drive the cleaning assembly 200 to its highest point and to control the shielding member 400 to move from the second position to the first position, thereby physically isolating the cleaning assembly 200 from the surface to be cleaned. When the sensor detects that the cleaning device has left the target area, the controller controls the drive mechanism 300 to drive the shielding member 400 from the first position to the second position, and to drive the cleaning assembly 200 to descend until it contacts the surface to be cleaned, and the first cleaning member 220 to rotate, so that the first cleaning member 220 can continue to clean the surface to be cleaned.

[0251] In another application scenario, when the sensor detects that the cleanliness level of the surface to be cleaned is very clean, in order to prevent the cleaning surface 220 from contaminating the surface to be cleaned, the controller is triggered to control the driving mechanism 300 to drive the cleaning component 200 to rise to the highest point, and control the covering member 400 to move from the second position to the first position, so as to achieve physical isolation between the cleaning component 200 and the surface to be cleaned. When the sensor detects that the cleanliness level of the surface to be cleaned reaches the level of dirtiness that requires the first cleaning member 220 to clean, the controller controls the driving mechanism 300 to drive the covering member 400 to move from the first position to the second position, and drives the cleaning component 200 to descend to contact with the surface to be cleaned, and the first cleaning member 220 to rotate, so that the first cleaning member 220 continues to clean the surface to be cleaned.

[0252] In another application scenario, when the first cleaning member 220 is a dry first cleaning member, such as a roller 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 roller brush member and affecting the subsequent cleaning of dust by the roller brush member, the controller controls the driving mechanism 300 to drive the cleaning component 200 to rise to the highest point, and controls the covering member 400 to move from the second position to the first position, so as to achieve physical isolation between the cleaning component 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 covering member 400 to move from the first position to the second position, and drives the cleaning component 200 to descend to contact with the surface to be cleaned, and the first cleaning member 220 rotates, so that the first cleaning member 220 continues to clean the surface to be cleaned.

[0253] Referring to the embodiment shown in Figures 13 to 17 , similar to the above-described embodiment, the drive mechanism 300 drives the shielding member 400 to move between a first position and a second position. Specifically, in this embodiment, the drive mechanism 300 drives the shielding member 400 to move between the first position and the second position on the side of the first cleaning member 220 facing away from the wiper rib 232. Furthermore, in this embodiment, the cleaning device further includes a sewage trough 231. Sewage scraped off the first cleaning member 220 by the wiper rib 232 flows along the wiper rib 232 into the sewage trough 231. As described above, in other embodiments, the sewage trough 231 may not be provided, and the sewage scraped off the first cleaning member 220 by the wiper rib 232 is directly sucked into the sewage box.

[0254] In one embodiment, referring to FIG. 16 and FIG. 17 , the scraper rib 232 is partially disposed in the sewage trough 231 and partially extends outside the sewage trough 231 to abut against the first cleaning member 220 to ensure that sewage flows smoothly into the sewage trough 231 .

[0255] In one embodiment, since the wiper rib 232 abuts against the first cleaning member 220 and squeezes the sewage off the first cleaning member 220, the wiper rib 220 is made of a relatively strong material, while the sewage tank 231 can be made of a common material such as plastic. In this embodiment, the sewage tank 231 and the wiper rib 232 can be two separate structures. This arrangement also facilitates the disassembly of the wiper rib 232 and the sewage tank 231, making them easier to clean.

[0256] In other embodiments, the sewage trough 231 and the wiper rib 232 may also be integrally formed.

[0257] 16 and 17 , similar to the above-described embodiment, the first cleaning member 220 is a roller-shaped structure, the shielding member 400 is an arc-shaped structure, and the center of curvature of the shielding member 400 is located on the side of the shielding member 400 facing the first cleaning member 220. The driving mechanism 300 drives the shielding member 400 to rotate about the first cleaning member 220. As shown in FIG16 , when the shielding member 400 is in the first position, the shielding member 400 covers the bottom portion of the first cleaning member 220 exposed from the accommodating cavity. As shown in FIG17 , when the shielding member 400 is in the second position, the bottom portion of the first cleaning member 220 is exposed from the accommodating cavity.

[0258] 14 and 15 , different from the embodiment of FIG. 1 to FIG. 12 , 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 drive the first cleaning member 220 to rotate.

[0259] Continuing with reference to Figures 14 and 15, 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 and meshes with the shielding member gear 430 on the side of the shielding member 400 facing away from the first cleaning member 220. As a result, the first output shaft 3211 drives the first output gear 3213 to rotate, and as the first output gear 3213 rotates, the shielding member 400 moves between the first position and the second position. Specifically, assuming that the first output shaft 3211 drives the first output gear 3213 to rotate in a first rotational 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 rotational direction opposite to the first rotational direction, the shielding member 400 moves from the second position to the first position.

[0260] Referring to FIG. 18 , in some embodiments, the outer circumferential surface of the shielding member 400 is provided with a groove 411, within which the shielding member gear 430 is disposed. The notch of the groove 411 is higher than the tooth top surface of the shielding member gear 430. This arrangement prevents the shielding member gear 430 from protruding and scratching the surface to be cleaned when the shielding member 400 is in the first position. Of course, in other embodiments, the groove 411 may not be provided.

[0261] 14 to 18 , in order to increase the rotation range of the shielding member 400 , the shielding member 400 is provided with a shielding member body 410 having an arc-shaped structure and a transmission arm 440 having an arc-shaped structure. The center of curvature of the shielding member body 410 is located on the side of the shielding member body 410 facing the first cleaning member 220. At the same time, the shielding member gear 430 is formed on the surface of the shielding member body 410 facing away from the first cleaning member 220 and extends along the circumference of the shielding member body 410. The transmission arm 440 is connected to 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 may not include the transmission arm 440 , and in this case, the shielding member gear 430 is only formed on the shielding member body 410 .

[0262] 14 to 18 , in one embodiment, a groove 411 is formed on the shielding member body 410 and the transmission arm 440 , and a shielding member gear 430 is formed on the groove 411 to prevent the shielding member gear 430 from protruding and scratching the surface to be cleaned when the shielding member 400 is in the first position.

[0263] Continuing to refer to FIG. 18 , in one 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.

[0264] Referring to Figures 14 and 15 , in some embodiments, there is one shielding gear 430, which is positioned axially midway around the shielding member 400. This arrangement maintains force balance on the shielding member 400 and ensures stable rotation of the shielding member 400. In this embodiment, when the shielding member 400 includes a shielding member body 410 and a transmission arm 440, there is one transmission arm 440, which is connected axially midway around the shielding member body 410.

[0265] Of course, in other embodiments, the shielding member gear 430 may also be disposed at an end position of the shielding member 400 in the axial direction.

[0266] 15, 16, and 17, in some embodiments, the housing 210 is fixedly connected to the bracket 100, and the bracket 100 and the cleaning assembly 200 are vertically synchronously raised and lowered. However, in other embodiments, the housing 210 and the bracket 100 may be vertically movable.

[0267] 13 , 14 , and 15 , in some embodiments, the driving mechanism 300 is fixedly mounted on the bracket 100 , and the driving mechanism 300 rises and falls synchronously with the bracket 100 in the vertical direction.

[0268] In some embodiments, referring to Figures 16 and 17 , the bracket 100 includes a plurality of connecting plates 120 , which are arranged to form a housing space within which the cleaning assembly 200 is disposed. In some embodiments, the housing 210 can be fixedly connected to one of the connecting plates 120 . Furthermore, in some embodiments, the housing 210 can be integrally formed with one of the connecting plates 120 .

[0269] 14 and 15 , in some embodiments, the shielding member 400 is disposed outside the accommodating cavity formed by the housing 210 and is supported by the housing 210. In other embodiments, the shielding member 400 may also be disposed inside the accommodating cavity formed by the housing 210, in which case the shielding member 400 may be supported by a support structure protruding from the side wall of the bracket 100.

[0270] In the embodiments of Figures 13 to 18 , the drive mechanism 300 only drives the shielding member 400 to rotate. However, a single drive mechanism 300 may be provided to simultaneously drive the cleaning assembly 200 to move vertically and the first cleaning member 220 to rotate. Alternatively, two drive mechanisms 300 may be provided, with one drive mechanism 300 driving the cleaning assembly 200 to move vertically and the other drive mechanism 300 driving the first cleaning member 220 to rotate.

[0271] 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 to the embodiments of Figures 13 to 18, and the driving mechanism 300 is further provided to include a second output end 322, and the second output end 322 is connected to the first cleaning member 220 to drive the first cleaning member 220 to rotate. For example, referring to the embodiment in Figure 3, the driving mechanism 300 is provided to include, in addition to the first output shaft 3211 and the first output gear 3213, a second output shaft 3221 and a second output shaft sleeve 3222, the second output shaft sleeve 3222 being mounted on the second output shaft 3221, and the second output shaft sleeve 3221 being connected to the first cleaning member 220, wherein the specific connection relationship between the second output shaft sleeve 3221 and the first cleaning member 220 can be referred to the above description and will not be repeated here.

[0272] 13 to 18 , a shielding member 400 may be provided to be 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 in the above description and will not be further elaborated here.

[0273] In addition, in the embodiment of Figures 13 to 18, the driving mechanism 300 may only include the driving motor 310 without the reducer 320. In this case, the output shaft of the driving motor 310 directly serves as the first output shaft 3211. However, the embodiment of Figures 1 to 12 may also be improved to provide the driving mechanism 300 including the driving motor 310 and the reducer 320. Similarly, in this case, the input end of the reducer 320 is also provided with a power coupling connection with the output end of the driving motor 310. The reducer 320 has a first output end 321 and a second output end 322, that is, a first output shaft 3211 and a second output shaft 3221 are provided in the reducer 320. The first output gear 3213 provided on the first output shaft 3211 drives the shielding member 400 to rotate, and the second output shaft sleeve 3222 installed on the second output shaft 3221 drives the first cleaning member 220 to rotate.

[0274] 19 to 26 , the difference from the embodiment of FIG. 13 to 18 is that there are multiple shielding member gears 430 , which are spaced apart in the axial direction of the shielding member body 410 ; the driving mechanism 300 further includes a transmission gear 330 and a transmission shaft 340 .

[0275] There are multiple transmission gears 330, and the multiple transmission gears 330 are arranged in a one-to-one correspondence with the multiple shielding member gears 430. The correspondingly arranged transmission gears 330 and the shielding member gears 430 are engaged with each other, wherein one of the multiple transmission gears 330 is engaged with the first output gear 3213; the transmission shaft 340 is arranged along the axial direction of the shielding member body 410, connecting the multiple transmission gears 330.

[0276] 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 via 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, the multiple transmission gears 330 and the multiple shielding gears 430 ultimately drive the shielding body 410 to rotate. The number of transmission gears 330 can be two, three, or more, without limitation. It is understood that the number of transmission gears 330 is equal to the number of shielding gears 430.

[0277] 22 , in one embodiment, there are two shielding member gears 430 , which are respectively disposed at two ends of the shielding member body 410 in the axial direction.

[0278] Referring to Figures 19 to 22, in some embodiments, the driving mechanism 300 also includes a cam 350, which is sleeved on the transmission shaft 340. At the same time, the cam 350 is limited in the limited space formed by the base 11 of the body and the limit member 12. At this time, the shell 210 is arranged in the accommodating space surrounded by the bracket 100, and the bracket 100 is fixedly connected to the shell 210. The first cleaning member 220 and the shielding member 400 are both arranged in the accommodating cavity formed by the shell 210, and the shielding member 400 is arranged on the peripheral side of the first cleaning member 220. At the same time, a gap 101 is formed between the two axial ends of the shell 210 and the bracket 100. The shielding member gear 430 on the shielding member 400 is exposed from the gap 101. The side of the shell 210 facing away from the first cleaning member 220 is connected to the connecting component 213, and the transmission shaft 340 passes through the connecting component 213.

[0279] Specifically, the limiting member 12 is a U-shaped structure, which is fixedly connected to the base 11 and cooperates to form a limiting space. The cam 350 is always in the limiting space. As the cam 350 rotates, the transmission shaft 340 moves vertically up and down. Since the transmission shaft 340 passes through the connecting component 213 connected to the outer shell 210, the transmission shaft 340 can drive the outer shell 210 to move vertically. Driven by the outer shell 210, the bracket 100 moves vertically up and down, and all structures in the bracket 100 move synchronously vertically up and down.

[0280] Referring to Figure 20 , in one embodiment, a shaft sleeve 341 is sleeved around the transmission shaft 340. The connecting assembly 213 may include a shaft sleeve bracket 2131 and a shaft sleeve retainer 2132. The shaft sleeve retainer 2132 is connected to the shaft sleeve bracket 2131, and the two cooperate to form a rotational space within which the shaft sleeve 341 is restrained. Specifically, the shaft sleeve 341 directly contacts the transmission shaft 340. A wear-resistant, self-lubricating material can be used to ensure stable rotation of the transmission shaft 340. In one embodiment, the shaft sleeve bracket 2131 is integrally formed with the housing 210.

[0281] 20 , in some embodiments, the drive motor 310 and the transmission shaft 340 are disposed on the same side of the housing 210 and the drive motor 310 is mounted on the housing 210. In some embodiments, referring to FIG20 , the output shaft of the drive motor 310 directly serves as the first output shaft 3211.

[0282] 20 and 21 , in some embodiments, both ends of the shielding member 400 are supported by support structures 102 disposed on opposite side walls of the bracket 100 (the opposite side walls being spaced apart in the axial direction of the first cleaning member 220). In some embodiments, to prevent interference between the first cleaning member 220 and the shielding member 400, a radial gap exists between the first cleaning member 220 and the shielding member 400.

[0283] 22 , in some embodiments, to ensure balanced force on the transmission shaft 340 , the cam 350 is sleeved at the middle of the transmission shaft 340 , that is, the distances from the cam 350 to both ends of the transmission shaft 340 are equal.

[0284] Referring to Figures 23 and 24, when the cam 350 rotates to the point 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 component 200 rises vertically to the highest point; referring to Figures 25 and 26, when the cam 350 rotates to the point 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 component 200 descends vertically to the lowest point.

[0285] Referring to Figures 23 and 24, in one embodiment, as the first output shaft 3211 rotates, when the transmission shaft 340 drives the cleaning component 200 to rise vertically to the highest point, the shielding member 400 moves to the first position; referring to Figures 25 and 26, when the transmission shaft 340 drives the cleaning component 200 to descend vertically to the lowest point, the shielding member 400 moves to the second position.

[0286] Referring to Figures 19 to 21, in order to ensure that the cleaning assembly 200 operates smoothly in the vertical direction relative to the base 11, a buffer column 214 is further provided on the top of the cleaning assembly 200. The buffer column 214 passes through the base 11 and is movably connected to the base 11. At the same time, an elastic member 215 is sleeved on the buffer column 214 and elastically supported 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 toward the base 11 and the elastic member 215 is compressed. 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 extends. The elastic member 215 can specifically be a spring or other structure, and this application does not limit the structure of the elastic member 215.

[0287] In the embodiment of Figures 19 to 26, the drive mechanism 300 can drive both the shielding member 400 and the cleaning assembly 200 to move vertically. However, the embodiment of Figures 19 to 26 can also be improved by referring to the above-mentioned improvement method for the embodiment of Figures 13 to 18. In this case, the drive mechanism 300 can be further configured to include a second output end 322, which is connected to the first cleaning member 220 to drive the first cleaning member 220 to rotate.

[0288] For example, in a specific example, a driving mechanism 300 is provided including a driving motor 310 and a reducer 320. Similarly, the input end of the reducer 320 is also provided with a power coupling connection with the output end of the driving motor 310. The reducer 320 has a first output end 321 and a second output end 322, that is, a first output shaft 3211 and a second output shaft 3221 are provided in the reducer 320. The second output shaft sleeve 3222 installed on the second output shaft 3221 drives the first cleaning member 220 to rotate. The first output gear 3213 sleeved on the first output shaft 3211 is engaged with one of the multiple transmission gears 330. The multiple transmission gears 330 are connected through the transmission shaft 340 and the multiple transmission gears 330 are correspondingly engaged with the multiple shielding member gears 430 on the shielding member 400. At the same time, a cam 350 is also sleeved on the transmission shaft 340.

[0289] In addition, in the embodiments presented in Figures 13 to 26, the embodiments of Figures 1 to 12 can also be referred to, and the cleaning equipment is further provided to include components such as a detection device 600, a sensor, and a controller, and the coordinated working process between the detection device 600, the sensor, and the controller can be the same as that of the embodiments of Figures 1 to 12. For details, please refer to the above-mentioned relevant content.

[0290] In addition, in the embodiments presented in Figures 13 to 26, the embodiments of Figures 1 to 12 can also be referred to, and the cleaning equipment is set to have a first working mode and a second working mode. For the specific processes of the first working mode and the second working mode, please refer to the above-mentioned related content and will not be repeated here.

[0291] 27 to 35 , another specific implementation scheme for driving the cleaning assembly 200 to move vertically using the drive mechanism 300 is described below. In this scheme, the bracket 100 is movably disposed on the body 1 and is movable relative to the body 1. For example, the bracket 100 is movable in an up-and-down direction relative to the body 1, where the up-and-down direction is the direction indicated by arrow R1 in the figures.

[0292] In this embodiment, a drive mechanism 300 is provided on the body 1, which drives the bracket 100 to rise and fall, thereby driving the first cleaning member 220 mounted on the bracket 100 to rise and fall together. When the first cleaning member 220 is required to clean the object being cleaned during a cleaning operation, the drive mechanism 300 mounted on the body 1 drives the bracket 100 downward, driving the first cleaning member 220 mounted on the bracket 100 downward until it contacts the object being cleaned, allowing the first cleaning member 220 to clean the object. The drive mechanism 300 mounted on the body 1 can also drive the bracket 100 upward, driving the first cleaning member 220 mounted on the bracket 100 upward until it is separated from the object being cleaned, thereby reducing contamination of the object by the first cleaning member 220 during a transfer operation. Therefore, the cleaning device can meet multiple different operating conditions.

[0293] In one embodiment, referring to FIG. 28 , FIG. 30 , FIG. 32 and FIG. 33 , the first cleaning member 220 is a mopping device.

[0294] Exemplarily, the mopping device may be a roller or a rotating cleaning disc.

[0295] Illustratively, the rotational centerline of the drum is substantially parallel to the horizontal direction.

[0296] Exemplarily, the rotation centerline of the cleaning disc is substantially parallel to the vertical direction.

[0297] In an embodiment of the present application, when the cleaning device requires a mopping device to mop the floor during cleaning operation, the drive mechanism 300 drives the bracket 100 to move the mopping device downward until it contacts the ground to perform mopping operations. After mopping is completed, dirt such as sewage remains on the mopping device. The drive mechanism 300 drives the bracket 100 to lift the mopping device upward. When the cleaning device is transferred to the base station after mopping, the raised mopping device will not come into contact with the ground or carpet, regardless of whether the cleaning device passes over the ground or carpet. The mopping device with residual dirt such as sewage will contaminate the ground and carpet due to the lowering of the mopping device. In addition, since the mopping device is lifted upward, a wet mopping device will not wet the carpet, and the cleaning device can pass smoothly over the carpet without wetting the carpet.

[0298] In one embodiment, the cleaning device further includes a second cleaning member, which may be a cleaning device. The second cleaning member is installed on the bracket 100 or the body 1 .

[0299] The cleaning device can clean the floor or carpet.

[0300] Exemplarily, the cleaning device can be a roller brush, which cleans the floor or carpet. For example, it cleans debris on the floor or carpet.

[0301] For example, the cleaning device is mounted on the body 1. The driving mechanism 300 drives the bracket 100 to move the mopping device upward and away from the carpet. The cleaning device moves over the carpet, and the cleaning device cleans the carpet. Since the mopping device moves upward and away from the carpet, the possibility of the wet mopping device wetting the carpet is reduced. As the cleaning device moves over the carpet, the cleaning device can clean the carpet while effectively reducing the possibility of the wet mopping device wetting the carpet.

[0302] For example, the first cleaning member 220 and the second cleaning member may be mounted on the same bracket 100 .

[0303] For example, there are at least two drive mechanisms 300, each of which is provided with a corresponding bracket 100. The mopping device is mounted on the bracket 100 corresponding to one of the drive mechanisms 300, and the cleaning device is mounted on the bracket 100 corresponding to the other drive mechanism 300. The cleaning device can be driven downward by the corresponding drive mechanism 300 to contact the carpet, and the mopping device can be driven upward by the corresponding drive mechanism 300 to disengage from the carpet.

[0304] In the embodiment of the present application, the cleaning device is used to sweep away dirt on the object being cleaned. Most of the dirt swept away will be separated from the cleaning device and collected, and the dirt remaining on the cleaning device is relatively small. Even if the cleaning device is installed on the body 1 so that the cleaning device is always in contact with the object being cleaned, the cleaning device will not cause significant contamination to the floor and / or carpet after cleaning. The installation of the cleaning device on the body 1 will not have a significant negative impact on the floor and carpet after cleaning. The cleaning device can be installed on the drive mechanism 300, and the drive mechanism 300 drives the bracket 100 to drive the cleaning device upward, which can still reduce the contamination of the cleaning device to the cleaned object to a certain extent.

[0305] In one embodiment, referring to Figures 28, 29, and 32, a drive mechanism 300 includes a driver 31 and an actuator 32. Driver 31 is disposed on body 1. Actuator 32 is connected to driver 31, and driver 31 drives actuator 32 to rotate. Actuator 32 has a lifting portion 3201 that protrudes radially from actuator 32. Lifting portion 3201 is disposed through bracket 100 so that bracket 100 is at least partially positioned above lifting portion 3201.

[0306] It should be explained that, referring to Figures 29 and 34, the radial direction of the actuator 32 is based on the cylindrical reference surface P. The central axis of the cylindrical reference surface P coincides with the central axis of rotation of the actuator 32. The radial direction of the actuator 32 is the radial direction of the cylindrical reference surface P.

[0307] It should be explained, referring to Figures 29 and 34 , that the lifting portion 3201 protrudes radially from the actuator 32. The outer contour of the actuator 32 surrounding the rotational axis of the actuator 32 has different distances from the rotational axis of the actuator 32. The lifting portion 3201 corresponds to the portion of the actuator 32 where the outer contour surrounding the rotational axis of the actuator 32 has a greater distance from the rotational axis of the actuator 32. Because the lifting portion 3201 protrudes radially from the actuator 32, at least one cylindrical reference surface P of a corresponding diameter exists. As a result, the outer contour of the actuator 32 surrounding the rotational axis of the actuator 32 is partially located on the side of the reference surface P facing the rotational axis of the actuator 32, while partially located on the side of the reference surface P facing away from the rotational axis of the actuator 32. For example, the driver 31 may be a motor.

[0308] Exemplarily, the motor is a horizontal motor.

[0309] Exemplarily, the driver 31 may be a rotary cylinder.

[0310] In this embodiment of the present application, because the lifting portion 3201 provided through the bracket 100 protrudes radially from the actuator 32, when the driver 31 drives the actuator 32 to rotate, the lifting portion 3201 of the actuator 32 gradually rotates above the actuator 32, thereby lifting the bracket 100 via the lifting portion 3201, thereby elevating the bracket 100 and the first cleaning member 220 mounted on the bracket 100. The driver 31 drives the actuator 32 to rotate, causing the lifting portion 3201 to move away from above the actuator 32, gradually reducing the radial dimension above the actuator 32. Accordingly, the bracket 100 gradually descends under the action of gravity. The driver 31 drives the actuator 32 with the radially protruding lifting portion 3201 to rotate, thereby driving the bracket 100 to rise and fall.

[0311] It is understandable that the solution of using the driver 31 to drive the actuator 32 to rotate and drive the lifting part 3201 to rotate and lift can reduce the volume of the driving mechanism 300.

[0312] It is understood that the driving mechanism 300 is not limited to a structure in which the driver 31 and the actuator 32 cooperate. For example, the driving mechanism 300 may not include the actuator 32, and the driver 31 may be a telescopic cylinder, which drives the bracket 100 to rise and fall through the telescopic cylinder.

[0313] In one embodiment, referring to Figures 28 and 29 , the actuator 32 includes a drive shaft 3202, a lifting shaft 3203, and a first connecting arm 3204. The drive shaft 3202 is connected to the driver 31, which drives the drive shaft 3202 to rotate. The lifting shaft 3203 is eccentrically arranged relative to the drive shaft 3202, and the lifting portion 3201 is formed on the lifting shaft 3203. There is at least one lifting shaft 3203. The first connecting arm 3204 is respectively connected to the drive shaft 3202 and at least one of the lifting shafts 3203.

[0314] Exemplarily, the lifting shaft 3203 is coaxially arranged with the driving shaft 3202 .

[0315] In the embodiment of the present application, the lifting shaft 3203 is eccentrically arranged with the drive shaft 3202, so that the lifting shaft 3203 radially protrudes from the drive shaft 3202. Accordingly, the lifting portion 3201 formed on the lifting shaft 3203 radially protrudes from the drive shaft 3202, thereby achieving the lifting portion 3201 protruding radially from the actuator 32. The eccentric lifting shaft 3203 is connected to the drive shaft 3202 via the first connecting arm 3204, and the drive shaft 3202 drives the lifting shaft 3203 to rotate together through the first connecting arm 3204.

[0316] In one embodiment, referring to Figures 28 and 29 , the actuator 32 further includes a support shaft 3205 and a second connecting arm 3206. The support shaft 3205 is spaced apart from the drive shaft 3202 along its axial direction and is rotationally connected to the body 1. The second connecting arm 3206 is connected to the support shaft 3205 and at least one of the lifting shafts 3203. The lifting shaft 3203 is located between the first connecting arm 3204 and the second connecting arm 3206. The drive shaft 3202 drives the support shaft 3205 to rotate together with it via the first connecting arm 3204, the lifting shaft 3203, and the second connecting arm 3206.

[0317] Illustratively, the support shaft 3205 is coaxially arranged with the drive shaft 3202 .

[0318] Referring to Figures 28 and 34 , the support shaft 3205 is coaxially arranged with the drive shaft 3202. The driver 31 rotates the corresponding drive shaft 3202, causing the first connecting arm 3204, the lifting shaft 3203, the second connecting arm 3206, and the support shaft 3205 to rotate together. The rotational axis of the actuator 32 is the target axis 3207, i.e., the central axis of the drive shaft 3202 and the support shaft 3205. The central axis of a reference plane P coincides with the target axis 3207. At least one cylindrical reference plane P of corresponding diameter exists, such that the diameters of the drive shaft 3202 and the support shaft 3205 are both smaller than the diameter of the reference plane P. The diameter of the reference plane P is smaller than the maximum distance between the outer contour of the lifting shaft 3203 and the target axis 3207, and the lifting shaft 3203 is at least partially located outside the reference plane P. For the entire actuator 32 , the diameter of the drive shaft 3202 and the support shaft 3205 are located within the reference plane P, and the lifting shaft 3203 is at least partially located outside the reference plane P, so that the lifting portion on the lifting shaft 3203 protrudes radially of the actuator 32 .

[0319] Please refer to Figure 35, which is a projection view generally along the target axis. Of the outer contours of actuator 32 surrounding the actuator's central axis of rotation (target axis 3207), the outer contours of drive shaft 3202 and support shaft surrounding target axis 3207 are both located within reference plane P, i.e., on the side of the reference plane facing target axis 3207. The outer contour of lift shaft 3203 surrounding target axis 3207 is at least partially located outside reference plane P, i.e., on the side of the reference plane P facing away from target axis 3207.

[0320] In this embodiment of the present application, one end of the actuator 32 is supported on the driver 31 via a drive shaft 3202, and the other end of the actuator 32 is supported on the body 1 via a support shaft 3205. This ensures that both ends of the actuator 32 are well supported, reducing the degree of overhang of the actuator 32. The eccentric lifting shaft 3203 is connected to the support shaft 3205 via a second connecting arm 3206, allowing the lifting shaft 3203 to drive the support shaft 3205 to rotate via the second connecting arm 3206.

[0321] In one embodiment, referring to FIG. 28 and FIG. 29 , there is only one lifting shaft 3203 , and the lifting shaft 3203 is connected to the first connecting arm 3204 and the second connecting arm 3206 , respectively.

[0322] In the embodiment of the present application, a guide shaft connected between the first connecting arm 3204 and the second connecting arm 3206 enables the entire guide shaft to have a larger contact area with the bracket 100, which is conducive to the bracket 100 to be raised and lowered more smoothly under the action of the lifting shaft 3203.

[0323] It is understood that the number of lifting shafts 3203 is not limited. Exemplarily, there are at least two lifting shafts 3203. The actuator 32 further includes a transition shaft and a third connecting arm. The transition shaft is coaxially arranged with the drive shaft 3202. A corresponding transition shaft and third connecting arm are provided between each two adjacent lifting shafts 3203. The third connecting arm is respectively connected to the transition shaft and the lifting shaft 3203. Exemplarily, the lifting shafts 3203 can be coaxial or non-coaxial.

[0324] It is understood that the specific structure of the actuator 32 in the embodiment of the present application is not limited. For example, the actuator 32 can be a crank or a cam.

[0325] In one embodiment, as shown in Figures 28 to 30 and 32 , a support frame 100 includes a main frame 11 and a lifting frame 12. A first cleaning member 220 is mounted on the main frame 11. The lifting frame 12 is detachably connected to the upper portion of the main frame 11. The lifting frame 12 and the main frame 11 enclose an execution area 13, and a lifting portion 3201 is disposed through the execution area 13.

[0326] It should be noted that the execution area 13 is the space enclosed by the lifting frame 12 and the main frame 11. This part of the space is located between the lifting frame 12 and the main frame 11, which are at least partially separated. The lifting part 3201 can pass through this part of the space corresponding to the execution area 13 to lift the lifting frame 12 upward.

[0327] For example, when the lifting unit 3201 drives the lifting frame 12 to rise and fall, the lifting unit 3201 that passes through the execution area 13 is located near the top of the execution area 13, and the lifting unit 3201 abuts against the bottom of the lifting frame 12. When the lifting unit 3201 descends and separates from the lifting frame 12, the lifting unit 3201 still passes through the execution area 13.

[0328] For example, referring to Figure 32, the lifting frame 12 is a plate-shaped structure. For example, the lifting frame 12 is a lifting top plate.

[0329] For example, referring to FIG. 32 , the lifting frame 12 is in the shape of a Chinese numeral “X”.

[0330] Exemplarily, the lifting frame 12 is connected to the main frame 11 by bolts.

[0331] In the embodiment of the present application, since the lifting frame 12 is detachably connected to the top of the main frame 11, during the installation of the actuator 32 and the driver 31, the actuator 32 can be first installed on the driver 31, the lifting frame 12 can be removed from the main frame 11, and the assembled actuator 32 and driver 31 can be installed as a whole from top to bottom on the main frame 11. The lifting frame 12 can then be installed on the main frame 11 so that the lifting portion 3201 passes through the execution area 13 enclosed by the lifting frame 12 and the main frame 11. The actuator 32 and the driver 31 can be installed as a whole in the vertical direction, which helps to save assembly space on the bracket 100 along the central axis of the actuator 32.

[0332] It is understood that the specific structural form of the bracket 100 is not limited. For example, the main frame 11 and the lifting frame 12 are non-detachably connected. For example, the main frame 11 and the lifting frame 12 can be welded or integrally formed.

[0333] In one embodiment, referring to FIG. 29 , the central axis of rotation of the actuator 32 is the target axis 3207 , and the span of the lifting frame 12 along the target axis 3207 is greater than or equal to 1 mm.

[0334] For example, referring to FIG. 29 , the span of the lifting frame 12 along the target axis 3207 is D1 , and D1 ≥ 1 mm.

[0335] Illustratively, the span of the carriage 12 along the target axis 3207 may be 1 mm, 2 mm, 3 mm, 5 mm, 10 mm, 20 mm, or 30 mm.

[0336] In an embodiment of the present application, the span of the lifting frame 12 along the target axis 3207 is greater than or equal to 1 mm, so that the span of the lifting frame 12 along the target axis 3207 is large enough. When the lifting part 3201 lifts the lifting frame 12 to raise the entire bracket 100, the situation where the bracket 100 and the cleaning parts installed on the bracket 100 are tilted along one end of the target axis 3207 can be alleviated.

[0337] In one embodiment, referring to FIG. 29 , the span of the lifting frame 12 along the target axis 3207 is greater than or equal to 2 mm.

[0338] For example, referring to FIG. 29 , the span of the lifting frame 12 along the target axis 3207 is D1, and D1 ≥ 2 mm.

[0339] Illustratively, the span of the carriage 12 along the target axis 3207 may be 2 mm, 3 mm, 5 mm, 10 mm, 20 mm, 25 mm, 30 mm, or 40 mm.

[0340] In the embodiment of the present application, the span of the lifting frame 12 along the target axis 3207 is greater than or equal to 2 mm. The span of the lifting frame 12 along the target axis 3207 is large, and the contact dimension between the lifting frame 12 and the lifting part 3201 along the target axis 3207 is longer, which is conducive to the lifting frame 12 being lifted more smoothly by the lifting part 3201.

[0341] In one embodiment, please refer to Figures 30 and 31, the body 1 is formed with a first limiting portion 111, and the cleaning equipment also includes a limiting member 5 connected to the bracket 100, the limiting member 5 has a second limiting portion 51, and the second limiting portion 51 is located above the first limiting portion 111. The second limiting portion 51 is used to abut against the first limiting portion 111 to determine the lowest position of the bracket 100.

[0342] Exemplarily, referring to FIG. 30 and FIG. 31 , the first limiting portion 111 protrudes upward from the body 1 .

[0343] 30 and 31 , the limiting member 5 is passed through the bracket 100 to be connected to the bracket 100. The second limiting portion 51 is a limiting flange.

[0344] For example, referring to FIG. 30 and FIG. 31 , the limiting member 5 is a limiting sleeve.

[0345] In the embodiment of the present application, since the limit member 5 is connected to the bracket 100, when the driving mechanism 300 drives the bracket 100 to descend, the downward moving bracket 100 drives the limit member 5 to move downward, so that the second limit portion 51 of the limit member 5 moves downward to abut against the first limit portion 111. The lowest position of the bracket 100 is determined by the abutment between the first limit portion 111 and the second limit portion 51, preventing the bracket 100 from descending too low, or preventing the bracket 100 from moving downward excessively and causing damage to more sensitive components under the action of gravity.

[0346] In one embodiment, please refer to Figures 28 to 30, the bracket 100 has a first trigger part 14, and the cleaning device also includes a first trigger switch 6 installed on the body 1. The first trigger switch 6 is located above the first trigger part 14. The driving mechanism 300 can drive the bracket 100 to rise so that the first trigger part 14 contacts the first trigger switch 6 for triggering.

[0347] Exemplarily, the first trigger switch 6 may be a push switch, an optical coupler detection switch, an infrared detection switch, a proximity switch, or the like.

[0348] For example, referring to FIG. 29 , the first trigger portion 14 protrudes from the bracket 100 .

[0349] In the embodiment of the present application, the first trigger part 14 is driven by the bracket 100 to trigger the first trigger switch 6 during the rising process, and the bracket 100 rises to the corresponding predetermined position. The first trigger switch 6 sends a signal that the bracket 100 has risen to the corresponding predetermined position.

[0350] In one embodiment, please refer to Figures 28 and 30, the bracket 100 has a second trigger part 15, and the cleaning device also includes a second trigger switch 7 installed on the body 1, and the second trigger switch 7 is located below the second trigger part 15. The driving mechanism 300 can drive the bracket 100 to descend so that the second trigger part 15 contacts the second trigger switch 7 for triggering.

[0351] Exemplarily, the second trigger switch 7 may be a press switch, an optical coupler detection switch, an infrared detection switch, a proximity switch, or the like.

[0352] Exemplarily, referring to FIG. 28 and FIG. 30 , the second trigger portion 15 is a contact arm.

[0353] In the embodiment of the present application, the second triggering portion 15 is driven to trigger the second triggering switch 7 during the descent of the bracket 100, and the bracket 100 moves down to the corresponding preset position, and the second triggering switch 7 sends a signal indicating that the bracket 100 has moved down to the corresponding preset position.

[0354] It is understandable that during the downward movement of the bracket 100 , the first limiting portion 111 and the second limiting portion 51 abut against each other to determine the lowest downward position of the bracket 100 , thereby preventing the second trigger portion 15 from crushing the second trigger switch 7 under the action of gravity.

[0355] In one embodiment, referring to Figures 27, 32 and 33, the cleaning device also includes a four-bar linkage 8, and the lines connecting the four hinge points 81 of the four-bar linkage 8 in sequence form a parallelogram. The four-bar linkage 8 is installed on the fuselage 1 at two adjacent hinge points 81 of the four hinge points 81, and the four-bar linkage 8 is installed on the bracket 100 at the other two adjacent hinge points 81 of the four hinge points 81. The connecting rod of the four-bar linkage 8 that spans the fuselage 1 and the bracket 100 is the first connecting rod 82, and the first connecting rod 82 is rotatably connected to the fuselage 1 and the bracket 100 respectively.

[0356] For example, referring to FIG. 33 , in the four-bar linkage 8 , the links connected to the two first links 82 at two adjacent hinge points 81 are second links 83 , and the two first links 82 and the two second links 83 are arranged to form a parallelogram.

[0357] Exemplarily, the fuselage 1 has a first partition, and among the four hinge points 81 of the four-bar linkage 8 , two hinge points 81 installed on the fuselage 1 are separated by the first partition.

[0358] Exemplarily, the bracket 100 has a second partition, and two of the four hinge points 81 of the four-bar linkage 8 installed on the fuselage 1 are separated by the second partition.

[0359] In the embodiment of the present application, the lines connecting the four hinge points 81 of the four-bar linkage 8 in sequence form a parallelogram, and the arrangement directions of the two hinge points 81 of the two first links 82, which are respectively connected to the bracket 100 for rotation, remain basically unchanged, which is conducive to suppressing the rotation of the bracket 100 in the vertical plane and can better guide the bracket 100 to rise and fall.

[0360] In one embodiment, the central axis of rotation of the actuator 32 is the target axis 3207, and the driver 31 drives the actuator 32 to rotate. When the actuator 32 rotates so that the lifting portion 3201 and the target axis 3207 are arranged in the up and down directions and the lifting portion 3201 is located above the target axis 3207, the torque of the bracket 100 on the actuator 32 is small. When the driver 31 stops working, it is beneficial for the bracket 100 and the cleaning component installed on the bracket 100 to maintain in the corresponding raised position.

[0361] In one embodiment, when the actuator 32 rotates so that the lifting portion 3201 and the target axis 3207 are arranged in the up and down direction and the lifting portion 3201 is located below the target axis 3207, when encountering an obstacle, the obstacle can lift the cleaning member and drive the bracket 100 to move upward. After crossing the obstacle, the bracket 100 and the cleaning member move downward under the action of gravity, which is beneficial for the entire machine to avoid obstacles.

[0362] In one embodiment, the cleaning device further includes a sensor assembly disposed on the body 1, the sensor assembly being used to detect the material of the surface to be cleaned. Based on the material of the surface to be cleaned measured by the sensor assembly, the drive mechanism 300 is controlled to drive the bracket 100 up and down. With this structural form, the sensor assembly measures the surface to be cleaned, making it possible to clearly determine the material of the surface to be cleaned by the cleaning device and to raise and lower the bracket 100 accordingly. When the sensor detects that the surface to be cleaned is carpet, the drive mechanism 300 drives the bracket 100 to raise the first cleaning member 220 to prevent the first cleaning member 220 from wetting the carpet. When the sensor detects that the surface to be cleaned is a non-carpet material, such as a floor that can be soaked with water, the drive mechanism 300 drives the bracket 100 to lower the first cleaning member 220, allowing the first cleaning member 220 to clean the surface to be cleaned.

[0363] Referring to FIG. 36 , in some embodiments, the cleaning device further includes a filtering structure.

[0364] The filtration structure may include a first filter assembly 2331 having a first filter gap 2331a and a second filter assembly 2332 having a second filter gap 2332a. The first filter gap 2331a is smaller than the second filter gap 2332a. The first filter assembly 2331 is disposed within a sewage tank 231, and at least the first filter assembly 2331 defines a filter space 233a having a water absorption area 233a1 within the sewage tank 231. The second filter assembly 2332 is disposed on a side of the first filter assembly 2331 facing away from the water absorption area 233a1 and upstream of the first filter assembly 2331 in the direction of sewage flow. In other embodiments, only the first filter assembly 2331 or only the second filter assembly 2332 may be provided.

[0365] Please refer to Figure 36 and Figure 37. The second filter component 2332 can be set in the sewage tank 231 or outside the sewage tank 231.

[0366] The second filter assembly 2332 is positioned within the sewage tank 231. While filtering sewage, the filtered lint and trash can be temporarily stored within the tank 231, facilitating subsequent cleanup. After entering the sewage tank 231, the sewage first flows through the second filter assembly 2332, then through the first filter assembly 2331, and into the filter space 233a with a water absorption area 233a1. The second filter assembly 2332 filters lint and large trash particles, while the first filter assembly 2331 filters lint and smaller trash particles. The sewage is then discharged from the sewage tank 231 through the water absorption area 233a1.

[0367] The filtering structure shown in Figure 36 only has a first filter component 2331 and a second filter component 2332. In other embodiments, the filtering structure may also have one or more other filter components between the first filter component 2331 and the second filter component 2332. For example, the filtering structure may include a third filter component (not shown) having a third filter gap. The third filter component is located between the first filter component 2331 and the second filter component 2332. The gap size of the third filter gap is larger than the filter gap of the first filter gap 2331a and smaller than the gap size of the second filter gap 2332a. The third filter component can filter medium-sized garbage, reduce the filtering pressure of the first filter component 2331, reduce the probability of the first filter component 2331 being blocked by garbage, and further enhance the filtering effect of the filtering structure.

[0368] 37 and 38 , in some embodiments, the cleaning apparatus further includes a sewage pipe 700 and a sewage box 800. The water inlet 700a of the sewage pipe 700 is disposed within the water inlet region 233a1, and the outlet 700b of the sewage pipe 700 is connected to the sewage box 800. Sewage scraped off the first cleaning member 220 by the scraping ribs 232 flows along the scraping ribs 232 into the sewage tank 231. After lint, large particles of garbage, and small particles of garbage are filtered by the filter structure, the sewage is drawn into the sewage box 800 through the sewage pipe 700 in the water inlet region 233a1.

[0369] In one embodiment, referring to FIG36 , the inner sidewall of the sewage trough 231 and the first filter assembly 2331 can collectively enclose a filter space 233a. In FIG36 , the inner sidewall of the sewage trough 231 on the side opposite the wiper rib 232 and the first filter assembly 2331 collectively enclose the filter space 233a. After being filtered by the first filter assembly 2331, sewage can enter the filter space 233a. Since most of the lint and garbage have been filtered out, the sewage in the filter space 233a can be pumped out of the sewage pipe, reducing the probability of sewage pipe clogging. In another embodiment, the inner sidewall of the sewage trough 231 on another side and the first filter assembly 2331 can collectively enclose the filter space 233a.

[0370] In another embodiment, the filtering space 233 a may be enclosed by only the first filtering component 2331 .

[0371] In one embodiment, please refer to Figure 36, a sedimentation tank 233a2 may be provided in the filter space 233a, and the sedimentation tank 233a2 surrounds the circumference of the water absorption area 233a1. There are some fine garbage particles in the sewage filtered by the first filter component 2331. When the sewage flows through the sedimentation tank 233a2, some of the fine particles can be settled in the sedimentation tank 233a2, which can further reduce the risk of garbage clogging the sewage pipe 700.

[0372] In one embodiment, referring to Figures 36, 37 and 38, the first filter assembly 2331 may include a plurality of first filter ribs 23311 spaced apart, with a first filter gap 2331a formed between two adjacent first filter ribs 23311. The first filter ribs 23311 have a simple structure, are easy to process and manufacture, and can be integrally formed with the sewage tank 231.

[0373] In another embodiment, the first filter assembly 2331 may include a filter mesh having a first filter gap 2331 a .

[0374] In one embodiment, referring to Figures 36, 37 and 38, the second filter assembly 2332 may include a plurality of second filter ribs 23321 spaced apart, with a second filter gap 2332a formed between two adjacent second filter ribs 23321. The second filter ribs 23321 have a simple structure, are easy to process and manufacture, and can be integrally formed with the sewage tank 231.

[0375] In another embodiment, the second filter assembly 2332 may include a filter mesh having a second filter gap 2332a.

[0376] In one embodiment, referring to FIG. 36 , the second filter assembly 2332 can be located on a side of the sewage trough 231 near the wiper rib 232. The sewage trough 231 is divided into a first area 231a1 and a second area 231a2. The first area 231a1 is located between the wiper rib 232 and the second filter assembly 2332, while the second area 231a2 is located on a side of the second filter assembly 2332 facing away from the first area 231a1. The first filter assembly 2331 is disposed within the second area 231a2. Waste filtered by the second filter assembly 2332 can be temporarily stored in the first area 231a1, while waste filtered by the first filter assembly 2331 can be temporarily stored in the second area 231a2, facilitating subsequent waste removal.

[0377] In one embodiment, please refer to Figures 36 and 38, the width of the first filter rib 23311 is smaller than the width of the second filter rib 23321. The width of the second filter rib 23321 is larger, which can reduce the probability of hair and large particles of garbage clogging the second filter gap 2332a and enhance the filtering effect.
