[0045] The existing cleaning equipment needs to be manually removed and cleaned after completing the cleaning of the building stairs, or the cleaning equipment is moved to the base station to clean the cleaning equipment with the cleaning tank of the base station. However, the manual removal and cleaning of the cleaning equipment increases the cleaning burden of the user, cannot realize the complete automation of the cleaning equipment, and makes the user feel poor. The cleaning of the cleaning equipment by the base station increases the overall cost of the cleaning equipment, increases the overall occupied area of the cleaning equipment, reduces the economic performance of the cleaning equipment, and makes the practicality of the cleaning equipment lower. In view of the above problems, the present application provides a cleaning equipment 100.

[0046] Reference Figures 1 to 10 In the embodiment of the present application, the cleaning equipment 100 has a height direction and a front-back direction, the cleaning equipment 100 comprises a cleaning main body 10, a supporting unit 30 and a moving mechanism 50, the bottom of the cleaning main body 10 is provided with a wiping and mopping piece 11; the supporting unit 30 is arranged below the bottom of the cleaning main body 10; the moving mechanism 50 connects the cleaning main body 10 and the supporting unit 30, the moving mechanism 50 comprises a first moving assembly 51 and a second moving assembly 53, the first moving assembly 51 is used to drive the supporting unit 30 to ascend and descend, and the second moving assembly 53 is used to drive the supporting unit 30 to move along the front-back direction. The surface of the supporting unit 30 facing the cleaning main body 10 is provided with a scraping piece 315, and the scraping piece 315 is used to abut against the wiping and mopping piece 11.

[0047] It is understood that when the cleaning device 100 is in operation, the moving mechanism 50 can be used to cause the cleaning device 100 to climb step by step from bottom to top along the stairs 200, or to descend step by step from top to bottom along the stairs 200. In this case, a device for driving the cleaning device 100 to move along the direction extending along the surface of the stairs 200 can be provided on the bottom of the cleaning body 10 or the support unit 30, so that the wiping member 11 of the cleaning body 10 can move left and right on the surface of the stairs 200 in a direction perpendicular to the front-to-back direction during the step-by-step movement along the stairs 200 to clean the stairs 200.

[0048] For example, the cleaning device 100 climbs up the stairs 200 from bottom to top. Figures 1 to 3 As shown, the process of the cleaning device 100 moving on the stair 200 and cleaning the stair 200 can be divided into a cleaning process and a climbing process. During the cleaning process, the cleaning device 100 can start operating from one side of the stair 200 in a direction perpendicular to the front-to-back direction. At this time, the first moving assembly 51 is used to drive the support unit 30 downward. Since the support unit 30 is now located on the surface of the stair 200, the interaction of forces can cause the first moving assembly 51 to reversely drive the cleaning body 10 upward, causing the cleaning body 10 to move toward the surface of the upper stair 200. When the bottom of the cleaning body 10 is flush with the surface of the upper stair 200, the first moving assembly 51 is stopped, and the second moving assembly 53 is used to drive the support unit 30 forward in the front-to-back direction. At this time, since the support unit 30 abuts the front riser connecting the upper and lower steps of the stair 200, the interaction of forces can cause the second moving assembly 53 to reversely drive the cleaning body 10 forward to the surface of the upper stair 200. When the cleaning body 10 abuts the front riser of the upper stair 200, the second moving assembly 53 can be stopped. At this time, a device can be set on the bottom of the cleaning body 10 or the support unit 30 to drive the cleaning equipment 100 to move along the extension direction of the surface of the stairs 200, so that the cleaning equipment 100 can be moved left and right along the surface of the stairs 200 as a whole, so that the wiping and mopping part 11 of the cleaning body 10 can abut against the surface of the stairs 200 and drag left and right to clean the stairs 200 at that level.

[0049] When the cleaning of the surface of the step of the stair 200 is completed, the cleaning device 100 can enter the climbing process, and the first moving assembly 51 can be started to drive the support unit 30 to ascend. By using the counterweight device or increasing the weight of the front half of the cleaning body 10, the overall center of gravity of the cleaning device 100 can be located in the front half, so that the cleaning device 100 can be kept stationary as a whole when the support unit 30 ascends, and the support unit 30 can be stably lifted in the height direction towards the bottom of the cleaning body 10. When the support unit 30 approaches the bottom of the cleaning body 10 and is flush with the upper step of the stair 200, the first moving assembly 51 is stopped, and the second moving assembly 53 is started to drive the support unit 30 to move forward. At this time, the lifting device can be arranged on the cleaning body 10, so that the lifting device can lift the cleaning body 10 or the wiping member 11 to a certain height to avoid the support unit 30, so that the support unit 30 can smoothly move forward between the cleaning body 10 and the surface of the stair 200. Alternatively, the bottom of the cleaning body 10 can be spaced apart from the surface of the stair 200 near the edge of the lower step of the stair 200, so that the support unit 30 can be located between the cleaning body 10 and the surface of the stair 200 when the support unit 30 moves forward to contact the edge of the surface of the stair 200. At this time, the first moving assembly 51 is started again to drive the support unit 30 to descend, so that the cleaning body 10 can be lifted a certain distance under the action of force, and then the support unit 30 can gradually move forward between the cleaning body 10 and the surface of the stair 200. Thus, the cleaning process and the climbing process can be cyclically performed when the cleaning device 100 operates, so that the cleaning device 100 can effectively climb and clean the steps of the stair 200 from bottom to top, and the automatic cleaning of the building stair 200 can be realized.

[0050] When the cleaning device 100 falls down step by step along the steps 200 from top to bottom, the cleaning device 100 can first be driven by the first moving assembly 51 to drive the support unit 30 to descend to the surface of the next step 200, and then a device for driving the cleaning device 100 to move along the extension direction of the surface of the step 200 can be arranged on the bottom of the cleaning main body 10 or the support unit 30, so that the cleaning device 100 moves left and right along the surface of the step 200 to realize cleaning of the surface of the step 200. When the cleaning is completed, the second moving assembly 53 can be started to drive the cleaning main body 10 to move backward, and when the second moving assembly 53 leaves the surface of the step 200, the first moving assembly 51 can be started again to drive the cleaning main body 10 to descend to the surface of the next step 200, so that the cleaning main body 10 moves to the next step 200, and finally the first moving assembly 51 is started to drive the support unit 30 to move backward and leave the surface of the step 200, and the above-mentioned actions can be cycled to realize the cleaning device 100 falling down step by step along the steps 200 from top to bottom, realize the movement and cleaning of the cleaning device 100 on the building steps 200, so that the cleaning device 100 can better realize the automatic cleaning of the building steps 200, and reduce the cleaning burden of the user.

[0051] The scraping piece 315 can be arranged on the surface of the support unit 30 facing the bottom of the cleaning main body 10. When the cleaning device 100 moves on the stairs 200, the scraping piece 315 can be abutted against the wiping and mopping piece 11 of the cleaning main body 10 during the movement of the support unit 30 along the front and back directions close to the bottom of the cleaning main body 10, so that the scraping piece 315 can scrape off the dirt on the wiping and mopping piece 11, realize the self-cleaning function of the wiping and mopping piece 11, and clean the wiping and mopping piece 11 after cleaning each step of the stairs 200, so that the cleaning device 100 can clean each step of the stairs 200 with a clean wiping and mopping piece 11, and improve the cleaning effect of the cleaning device 100. At this time, a dirt collecting device or a dirt pumping device can be arranged on the bottom of the cleaning main body 10 or the support unit 30 to collect the dirt cleaned by the scraping piece 315, so as to avoid the cleaned dirt from directly falling on the stairs 200. Alternatively, when the cleaning of the stairs 200 is completed, the cleaning device 100 can be moved to a specific position by using the walking device 311, the specific position can be a corner of the stairs 200 or an idle position of the cleaning device 100 in the building, and a lifting frame can be arranged at the specific position, so that the cleaning device 100 can be lifted to a certain height by the lifting frame in the specific position, then the support unit 30 can be moved to the position below the wiping and mopping piece 11 by using the moving mechanism 50, so that the scraping piece 315 abuts against the surface of the wiping and mopping piece 11 facing away from the cleaning main body 10, and then the dirt on the wiping and mopping piece 11 can be scraped into the dirt collecting device at the bottom of the lifting frame during the movement of the support unit 30 driven by the moving mechanism 50, and a spraying device and a sewage recycling device can be arranged at the bottom of the lifting frame, so that the lifting frame can also spray and recycle the sewage after cleaning the wiping and mopping piece 315, realizing the self-cleaning function of the cleaning device 100. By arranging the scraping piece 315 on the support unit 30, the self-cleaning function of the cleaning device 100 can be effectively realized, so that the user does not need to regularly disassemble the wiping and mopping piece 11 of the cleaning main body 10 for cleaning, and does not need to equip a base station corresponding to the cleaning device 100 to clean the wiping and mopping piece 11 of the cleaning device 100, which is conducive to better reducing the overall cost of the cleaning device 100, reducing the burden of the user, meeting the actual use demand of the user, and effectively improving the overall structural reliability and practicality of the cleaning device 100.

[0052] In the embodiment of the present application, the wiping and mopping member 11 can be a brush or a cloth board or the like with a certain cleaning effect, and the cleaning effect on the surface of the staircase 200 is achieved by the wiping and mopping member 11 contacting the surface of the staircase 200 and wiping in the left-right direction. The scraping member 315 can adopt a scraping strip structure with a certain rigidity or a protruding structure formed on the surface of the support unit 30, so that the scraping member 315 can better contact the wiping and mopping member 11 during the movement of the support unit 30 close to the bottom of the cleaning main body 10 and in the front-back direction, increase the contact area between the scraping member 315 and the wiping and mopping member 11, and achieve better cleaning effect.

[0053] The technical scheme of the present application can make the cleaning device 100 climb or fall along the steps of the staircase 200 when cleaning the building staircase 200, realize the automatic cleaning operation of the cleaning device 100 on the building staircase 200, and reduce the cleaning burden of the user. By providing the scraping member 315 on the surface of the support unit 30 facing the cleaning main body 10, the scraping member 315 can abut against the wiping and mopping member 11 when the support unit 30 approaches the wiping and mopping member 11 at the bottom of the cleaning main body 10, so that the scraping member 315 can scrape and clean the wiping and mopping member 11 during the movement of the support unit 30 in the front-back direction, realize the self-cleaning function of the cleaning device 100 on the wiping and mopping member 11 of the cleaning main body 10, and thus the user does not need to manually clean the wiping and mopping member 11 and does not need to equip a base station to clean the cleaning device 100, effectively improving the practicality and structural reliability of the cleaning device 100, meeting the practicality requirement of the user, and optimizing the use experience of the user.

[0054] Referring to Figure 4 , Figure 9 and Figure 10 In an embodiment of the present application, the surface of the support unit 30 facing the cleaning main body 10 is also provided with a cleaning groove 313, and the scraping member 315 is arranged in the cleaning groove 313.

[0055] In the embodiment, by arranging the cleaning groove 313 on the surface of the cleaning main body 10 facing the supporting unit 30, and arranging the scraping member 315 in the cleaning groove 313, the scraping member 315 can better drop the garbage and dirt cleaned from the wiping and mopping member 11 into the cleaning groove 313 during the movement of the supporting unit 30 driven by the moving mechanism 50 to move close to the wiping and mopping member 11, so that the cleaning groove 313 can play a role of temporarily storing the dirt during the self-cleaning of the cleaning equipment, avoiding the garbage and dirt cleaned during the self-cleaning of the cleaning equipment 100 from falling around the cleaning equipment 100 to cause secondary pollution, and further improving the overall structural reliability and stability of the cleaning equipment 100, and guaranteeing the cleaning effect of the cleaning equipment 100. The cleaning main body 10 can be provided with a dirt suction device for sucking the dirt in the cleaning groove 313, or a dirt collecting device can be arranged in the supporting unit 30 and communicated with the cleaning groove 313, and the cleaning equipment 100 can automatically move to a garbage recycling place in the base station or the building after completing cleaning to clean the collected garbage, and guarantee the automatic operation of the cleaning equipment 100.

[0056] With reference to Figure 4 , Figure 9 and Figure 10 , in an embodiment of the present application, the scraping member 315 is movably connected to the cleaning groove 313 in the front-rear direction.

[0057] It can be understood that one scraping member 315 extending in the length direction of the cleaning groove 313 can be arranged in the cleaning groove 313 at a certain interval in the front-rear direction, or a scraping array composed of a plurality of scraping members 315 can be arranged on the groove bottom wall of the cleaning groove 313, so that the scraping member 315 can more comprehensively contact and clean the entire wiping and mopping member 11.

[0058] In the embodiment, by arranging the scraping member 315 to move in the cleaning groove 313 in the front-rear direction, the scraping member 315 can better scrape the entire wiping and mopping member 11 by moving in the front-rear direction on the surface of the wiping and mopping member 11 away from the cleaning main body 10 during the abutting and cleaning of the wiping and mopping member 11 by the scraping member 315, so as to achieve a more comprehensive and reliable cleaning effect, and effectively improve the self-cleaning effect of the cleaning equipment 100, and further improve the structural reliability and practicality of the cleaning equipment 100.

[0059] Further, with reference to Figure 9 and Figure 10 , in an embodiment of the present application, the inner side wall of the cleaning groove 313 is provided with a guide slide rail 3131, and the end of the scraping member 315 is movably inserted into the guide slide rail 3131.

[0060] In the embodiment, the end of the scraping member 315 is inserted into the guide sliding rail 3131 arranged on the inner side wall of the cleaning tank 313, so that the scraping member 315 can move in the front-rear direction along the extension direction of the guide sliding rail 3131 under the guidance of the guide sliding rail 3131, thereby achieving the overall cleaning of the wiping and mopping member 11 by the scraping member 315. The scraping member 315 can be moved in the cleaning tank 313 by being in contact with the wiping and mopping member 11 and moving relative to the wiping and mopping member 11 along the guide sliding rail 3131 under the friction force between the scraping member 315 and the wiping and mopping member 11. Alternatively, a transmission tooth belt or a connecting rod can be arranged in the guide sliding rail 3131 to connect the end of the scraping member 315, and a driving mechanism in the support unit 30 is used to drive the transmission tooth belt or the connecting rod to move the scraping member 315 in the cleaning tank 313.

[0061] In an embodiment of the present application, the support unit 30 is provided with a first driving device for driving the scraping member 315 to move in the cleaning tank 313.

[0062] In the embodiment, the support unit 30 can be provided with the first driving device below the scraping member 315 or at both ends of the scraping member 315. The first driving device can be a telescopic push rod device or a motor gear transmission assembly, so that the support unit 30 can directly drive the scraping member 315 to move in the cleaning tank 313 in the front-rear direction by using the first driving device, thereby achieving the comprehensive cleaning effect of the wiping and mopping member 11 by the scraping member 315 and further improving the overall structural reliability and practicability of the cleaning device 100. When the support unit 30 is provided with a driving device for moving the cleaning device 100, the first driving device can also have a certain linkage mechanism with the driving device arranged in the support unit 30, so that the movement of the support unit 30 and the movement of the scraping member 315 can be switched by changing the linkage mechanism, so that the cleaning device 100 can realize the driving of multiple movement structures by using one power source, thereby reducing the overall driving power source of the cleaning device 100, further reducing the production cost of the cleaning device 100, and improving the practicability of the cleaning device 100.

[0063] Referring to Figure 4 , Figure 9 and Figure 10 , in an embodiment of the present application, the cleaning tank 313 is provided with a nozzle 3133 facing the wiping and mopping member 11.

[0064] In the embodiment, by arranging the nozzle 3133 in the cleaning tank 313, the nozzle 3133 can be arranged on the tank bottom wall or the inner side wall of the cleaning tank 313 and faces the mop 11, so that the cleaning device 100 can spray water mist to the mop 11 by using the nozzle 3133 during the self-cleaning process of scraping the mop 11 by using the scraping member 315, so that the cleaning device 100 can realize the wet cleaning function of the mop 11, and by increasing the pressure of the water column sprayed by the nozzle 3133, the high-pressure water column can also be used to better flush the dirt on the mop 11, further improve the cleaning effect of the mop 11, so that the self-cleaning effect of the cleaning device 100 is better, and the structural reliability and practicability of the cleaning device 100 are further improved.

[0065] When the cleaning device 100 starts the self-cleaning function of the mop 11 by moving to the base station or the idle position of the cleaning device 100 in the building, the nozzle 3133 can be communicated with the water supply element in the base station to realize water supply, and the garbage collection device in the base station is communicated with the cleaning tank 313 to realize the recovery of garbage and dirt; or a water storage device with large capacity can be arranged at the idle position of the cleaning device 100 in the building, so that the nozzle 3133 is communicated with the water storage device to realize water supply after the cleaning device 100 is parked, and the garbage recovery device at the position recovers and processes the garbage scraped into the cleaning tank 313, so as to ensure the automatic operation of the cleaning device 100 and simplify the operation of the cleaning device by the user.

[0066] Secondly, the nozzle 3133 can also be arranged on the scraping member 315, so that the nozzle 3133 forms an integrated structure with the scraping member 315, and the scraping member 315 can directly spray water to the mop 11 for wet cleaning when the scraping member 315 scrapes and cleans the mop 11, so as to improve the self-cleaning effect of the cleaning device 100.

[0067] Referring to Figure 7 , Figure 9 and Figure 10 In an embodiment of the present application, the support unit 30 is provided with a clean water tank, the nozzle 3133 is communicated with the clean water tank, and one side of the support unit 30 is provided with a water inlet hole 317 communicated with the clean water tank. The bottom of the cleaning main body 10 is also provided with a water injection pipe 153, which is used to plug the water inlet hole 317.

[0068] It can be understood that the cleaning device 100 can be provided with a water tank for storing clean water in the cleaning body 10 or the supporting unit 30, and the water supply of the nozzle 3133 can be realized by connecting the nozzle 3133 and the water tank through a hose, wherein the cleaning body 10 can directly store clean water in the water tank on the surface opposite to the supporting unit 30, or the cleaning body 10 can be formed into a certain bearing structure, and the clean water tank in other devices carried by the cleaning body 10 can be connected with the water injection structure on the cleaning body 10 to realize the water supply of the supporting unit 30 by the cleaning body 10. In the embodiment, the clean water tank can be arranged in the supporting unit 30 and located below the cleaning tank 313, at this time, the nozzle 3133 can be directly arranged at the through hole of the inner wall of the cleaning tank 313 communicating with the clean water tank, or when the nozzle 3133 and the clean water tank are connected by a hose, the laying length of the hose can be effectively reduced, the pipeline arrangement in the supporting unit 30 is reduced, and the miniaturization design of the supporting unit 30 is facilitated. However, due to the overall structure of the supporting unit 30, the capacity of the clean water tank arranged in the supporting unit 30 is small, at this time, the water inlet hole 317 communicating with the clean water tank can be arranged on one side of the supporting unit 30, and a rubber valve can be arranged on the inner wall of the water inlet hole 317 to seal the water inlet hole 317 by the rubber valve when the water injection plug 153 is not inserted, so as to store the water amount in the clean water tank. At this time, the water injection plug 153 can be arranged on the bottom of the cleaning body 10, so that when the supporting unit 30 rises to close to the bottom of the cleaning body 10, the water injection plug 153 is inserted into the water injection hole to open the rubber valve, or the water injection plug 153 can be arranged on the front side of the bottom of the cleaning body 10, so that when the supporting unit 30 moves forward, the water injection plug 153 is inserted into the water injection hole, so that the water storage device with larger capacity arranged in the cleaning body 10 can better supply water to the clean water tank in the supporting unit 30 through the water injection plug 153, realize the automatic replenishment of the clean water tank, further improve the automation operation of the cleaning device 100, and improve the structural reliability and practicality of the cleaning device 100.

[0069] In an embodiment of the present application, the nozzle 3133 communicates with the cleaning tank 313, and the bottom of the cleaning body 10 is further provided with a water injection hole located above the slot of the cleaning tank 313 when the supporting unit 30 is close to the cleaning body 10.

[0070] In the embodiment, the bottom of the cleaning main body 10 can be provided with a water injection hole communicating with the water storage structure in the cleaning main body 10, and when the support unit 30 rises to close to the bottom of the cleaning main body 10, the cleaning groove 313 can be arranged corresponding to the water injection hole, so that the water injection hole is located above the slot of the cleaning groove 313. At this time, the water injection hole is opened, so that the cleaning main body 10 can inject clean water into the cleaning groove 313 through the water injection hole. Further, during the movement of the support unit 30 in the front and back directions to make the scraping piece 315 abut against the wiping piece 11, the nozzle 3133 can extract clean water in the cleaning groove 313 to spray on the wiping piece 11 to realize wet cleaning of the wiping piece 11. During the cleaning process, the scraping piece 315 can scrape the sewage on the wiping piece 11 into the cleaning groove 313. At this time, the sewage in the cleaning groove 313 can be discharged by using the sewage discharge structure in the cleaning groove 313, so that the clean water can be injected into the cleaning groove 313 through the water injection hole before the next cleaning of the wiping piece 11, so as to ensure the self-cleaning effect of the cleaning equipment 100, and further improve the practicability and structural reliability of the cleaning equipment 100.

[0071] Referring to Figure 6 , Figure 7 , Figure 9 and Figure 10 , in an embodiment of the application, a sewage tank is arranged in the support unit 30, the groove bottom wall of the cleaning groove 313 is provided with a drain port 3135 communicating with the sewage tank, and one side of the support unit 30 is provided with a sewage discharge hole 319 communicating with the sewage tank. The bottom of the cleaning main body 10 is further provided with a sewage discharge pipe 155, which is used to plug the sewage discharge hole 319.

[0072] In the embodiment, by arranging the sewage tank in the support unit 30, the sewage in the cleaning groove 313 can be directly temporarily stored by using the sewage tank, which is beneficial to reduce the sewage discharge pipeline between the cleaning groove 313 and the cleaning main body 10, and facilitate the miniaturization design of the cleaning equipment 100. The sewage tank can be arranged in the support unit 30 corresponding to the position below the cleaning groove 313, and the drain port 3135 communicating with the sewage tank is arranged on the groove bottom wall of the cleaning groove 313 to discharge water, which can effectively reduce the pipeline arrangement in the support unit 30, and is beneficial to better reduce the overall volume of the support unit 30. Of course, the application is not limited to this, and in other embodiments, a shorter hose can be used to communicate the drain port 3135 of the cleaning groove 313 and the sewage tank to realize the sewage discharge in the cleaning groove 313, so as to avoid that the accumulation of too much sewage in the cleaning groove 313 affects the self-cleaning effect of the cleaning equipment 100, and further improves the structural reliability and practicability of the cleaning equipment 100.

[0073] And limited to the volume of the support unit 30, the sewage tank capacity in the support unit 30 is small, at this time, the sewage hole 319 communicating with the sewage tank can be arranged on one side of the support unit 30, and a rubber valve can be arranged on the inner wall of the sewage hole 319, so that the sewage hole 319 can be sealed by the rubber valve when it is not inserted with the sewage plug pipe 155, and the storage of sewage in the sewage tank is guaranteed. At this time, by arranging the sewage plug pipe 155 on the bottom of the cleaning main body 10, the sewage plug pipe 155 can be inserted into the sewage hole 319 to open the rubber valve when the support unit 30 rises to the bottom of the cleaning main body 10, or the sewage plug pipe 155 can be arranged on the front side of the bottom of the cleaning main body 10, so that the sewage plug pipe 155 is inserted into the sewage hole 319 when the support unit 30 moves forward, so that the larger capacity sewage storage device arranged in the cleaning main body 10 can better extract the sewage in the sewage tank of the support unit 30 through the sewage plug pipe 155, realize the automatic sewage operation of the support unit 30, further improve the automatic operation of the cleaning equipment 100, and improve the structural reliability and practicality of the cleaning equipment 100. Among them, the cleaning main body 10 can directly arrange a sewage storage tank on the surface facing away from the support unit 30, so that the sewage storage tank communicates with the sewage plug pipe 155 to realize the sewage extraction of the sewage tank in the support unit 30; or a certain bearing structure can be formed on the cleaning main body 10, a larger capacity sewage storage device is arranged in other equipment carried by the cleaning main body 10, so that the sewage storage device of other equipment communicates with the sewage plug pipe 155 on the cleaning main body 10, and then the sewage in the sewage tank of the support unit 30 can be stored in other equipment through the sewage plug pipe 155 to realize the automatic sewage of the cleaning equipment 100.

[0074] Secondly, when the cleaning main body 10 and the support unit 30 are respectively provided with corresponding water injection structures, the sewage structure and the water injection structure can be arranged on the same side of the support unit 30 and the same side of the cleaning main body 10, which is beneficial to better meet the overall structural arrangement requirements of the cleaning equipment 100, and facilitate the miniaturization of the cleaning equipment 100. The sewage structure and the water injection structure can be arranged at a certain interval along the length direction of the support unit 30, or can be arranged at a certain interval along the height direction of the support unit 30, and at this time, the water injection structure can be located above the sewage structure, which is beneficial to better realize the self-cleaning, water injection and sewage of the support unit 30.

[0075] Referring to Figures 4 to 8 In an embodiment of the present application, the wiping and mopping member 11 is connected to the bottom of the cleaning main body 10 in a lifting manner, the bottom of the cleaning main body 10 forms an avoiding space when the wiping and mopping member 11 is lifted, and the height of the support unit 30 along the height direction is smaller than the width of the avoiding space along the height direction.

[0076] In the embodiment, the mop 11 can be better lowered to close to the surface of the stairs 200 for cleaning when the cleaning main body 10 is placed on the surface of the stairs 200, so that a better cleaning effect is achieved. Meanwhile, during the process of the cleaning device 100 climbing the stairs 200 for cleaning, the support unit 30 can be lifted to close to the cleaning main body 10, so that the mop 11 is lifted at the bottom of the cleaning main body 10, so that the bottom of the cleaning main body 10 can form a certain avoiding space. By making the height of the support unit 30 in the height direction less than the width of the avoiding space in the height direction, the support unit 30 can better move forward into the avoiding space, so that the support unit 30 moves from the surface of the next level of stairs 200 to the surface of the upper level of stairs 200. During the process of the support unit 30 entering the avoiding space, the scraping piece 315 of the cleaning groove 313 can abut against and scrape the mop 11 to realize the self-cleaning function of the support unit 30 on the mop 11, so as to protect the automatic operation of the cleaning device 100. By lifting and lowering the mop 11 on the cleaning main body 10, the self-cleaning function of the mop 11 can be realized while the cleaning device 100 moves on the stairs 200, and the support unit 30 can be better moved between the cleaning main body 10 and the surface of the stairs 200 to realize the movement of the cleaning device 100 on the stairs 200, so as to further improve the overall structural reliability and stability of the cleaning device 100. The mop 11 can be lifted and lowered by the telescopic pull rod structure arranged in the cleaning main body 10, or the cam structure can be used to contact the mop 11 to realize the rotation of the cam structure to drive the movement of the mop 11 to realize the lifting of the mop 11.

[0077] Referring to Figure 4 , Figure 5 , Figure 6 and Figure 8 In an embodiment of the present application, the bottom of the cleaning main body 10 is provided with a swing mechanism 13, the swing mechanism 13 comprising a second driving device 131 and a swing plate 133, the second driving device 131 being installed on the cleaning main body 10; the swing plate 133 being connected to the second driving device 131 and abutting against the surface of the mop 11 facing the bottom of the cleaning main body 10, the swing plate 133 being arranged to extend in the front-rear direction, the second driving device 131 driving the swing plate 133 to swing in the direction towards or away from the bottom of the cleaning main body 10, so as to lift the mop 11 by the swing plate 133.

[0078] In the embodiment, the swing plate 133 can be arranged between the bottom of the cleaning main body 10 and the wiping and mopping piece 11 and extend along the front and back directions. At this time, the second driving device 131 can adopt a rotating speed motor. By connecting the rotating rod of the second driving device 131 to the end of the swing plate 133 close to the bottom of the cleaning main body 10, the second driving device 131 can drive the swing plate 133 to swing with one side of the swing plate 133 as the rotating center axis, so that when the swing plate 133 swings towards the direction away from the bottom of the cleaning main body 10, the wiping and mopping piece 11 can be pushed by the side of the swing plate 133 away from the cleaning main body 10, so that the wiping and mopping piece 11 moves towards the direction away from the cleaning main body 10, and then the swing plate 133 can drive the wiping and mopping piece 11 to descend. The side of the swing plate 133 away from the cleaning main body 10 can be rotationally connected with the wiping and mopping piece 11, or an elastic structure with a certain elasticity can be arranged between the wiping and mopping piece 11 and the bottom of the cleaning main body 10, so that when the second driving device 131 drives the swing plate 133 to swing towards the bottom of the cleaning main body 10, the wiping and mopping piece 11 can be pulled by the swing plate 133 or be subjected to the elastic restoring force of the elastic structure, so that the wiping and mopping piece 11 can ascend towards the bottom of the cleaning main body 10 along the swing of the swing plate 133, and then the swing plate 133 can drive the wiping and mopping piece 11 to ascend, so as to realize the ascending and descending operation of the wiping and mopping piece 11 at the bottom of the cleaning main body 10, further guarantee the automatic operation of the cleaning equipment 100, and improve the structural reliability and stability of the cleaning equipment 100.

[0079] By setting the swing mechanism 13 between the cleaning main body 10 and the wiping and mopping piece 11 to drive the wiping and mopping piece 11 to lift and drop, compared with the mode of driving the wiping and mopping piece 11 to lift and drop by using the telescopic push rod and the cam structure, it is beneficial to better reduce the occupied volume of the lifting and dropping structure on the cleaning main body 10, facilitate the miniaturization design of the cleaning equipment 100, and facilitate the reduction of the interference of the wiping and mopping piece 11 and the swing mechanism 13 to the space above the cleaning main body 10, so that the upper part of the cleaning main body 10 facing away from the support unit 30 can be better used to set other parts to realize the miniaturization design, or the cleaning main body 10 can form a better bearing structure, so that the cleaning equipment 100 can also realize a certain transportation function when moving and cleaning on the building stairs 200, further enriching the functionality of the cleaning equipment 100 and improving the practicality and structural reliability of the cleaning equipment 100. The length of the swing plate 133 in the front-rear direction can be set according to the width of the wiping and mopping piece 11 in the front-rear direction, so that the swing of the swing plate 133 under the driving action of the second driving device 131 can better drive the wiping and mopping piece 11 to lift and drop. The length of the swing plate 133 in the front-rear direction can be slightly greater than half of the width of the wiping and mopping piece 11 in the front-rear direction, which is beneficial to better act on the whole of the wiping and mopping piece 11 during the swing of the swing plate 133, so that the wiping and mopping piece 11 can better follow the whole lifting and dropping of the swing plate 133, reduce the deviation of the wiping and mopping piece 11 during the lifting and dropping, and further improve the structural reliability of the cleaning equipment 100. In addition, the swing plate 133 can also be set at the center position of the wiping and mopping piece 11 at the bottom of the cleaning main body 10, so that the whole wiping and mopping piece 11 can be more evenly affected by the force of the swing plate 133, and the wiping and mopping piece 11 can be more stably and reliably lifted and dropped.

[0080] Referring to Figures 4 to 6 In an embodiment of the present application, the wiping and mopping piece 11 is provided with a guide groove 111 facing the surface of the cleaning main body 10, the guide groove 111 extends in a direction perpendicular to the front-rear direction, and the swing plate 133 is provided with a traction protrusion 1331 movably inserted into the guide groove 111.

[0081] In the embodiment, the guide groove 111 is arranged on the surface of the wiping and mopping piece 11 facing the cleaning main body 10, and the traction protrusion 1331 on the swing plate 133 is inserted into the guide groove 111. The traction protrusion 1331 can be arranged on the end face of the swing plate 133 close to the wiping and mopping piece 11. At this time, the guide groove 111 can limit the movement of the traction protrusion 1331. When the wiping and mopping piece 11 swings towards the bottom of the cleaning main body 10, the traction protrusion 1331 can slide along the extension direction of the guide groove 111 with the swing of the swing plate 133. In turn, the wiping and mopping piece 11 can be lifted by the wiping and mopping piece 11 under the interaction of the traction protrusion 1331 and the guide groove 111. The effect of lifting the wiping and mopping piece 11 by the swing plate 133 in the swing process is realized, and the overall structural stability and reliability of the cleaning equipment 100 are further improved. The swing plate 133 can be provided with traction protrusions 1331 on both end faces close to the wiping and mopping piece 11 in the front-back direction, and the guide grooves 111 corresponding to the two ends of the swing piece are arranged on the surface of the wiping and mopping piece 11. In this way, the wiping and mopping piece 11 can be better lifted by the swing plate 133, and the cleaning equipment 100 can operate more stably and reliably.

[0082] With reference to Figure 8 In an embodiment of the present application, the swing mechanism 13 further comprises an elastic member 135 arranged between the bottom of the cleaning main body 10 and the wiping and mopping piece 11. The two ends of the elastic member 135 are connected to the cleaning main body 10 and the wiping and mopping piece 11, respectively.

[0083] In the embodiment, the elastic member 135 is arranged between the bottom of the cleaning main body 10 and the wiping and mopping piece 11. The elastic member 135 can be a spring or a soft rubber pad with certain elasticity. The two ends of the elastic member 135 are connected to the cleaning main body 10 and the wiping and mopping piece 11, respectively. When the swing plate 133 swings away from the bottom of the cleaning main body 10 and drives the wiping and mopping piece 11 to descend, the wiping and mopping piece 11 stretches the elastic member 135 to deform elastically. In the process of the swing plate 133 swinging towards the bottom of the cleaning main body 10, the elastic member 135 recovers the elastic deformation to drive the wiping and mopping piece 11 to ascend towards the bottom of the cleaning main body 10. In this way, the swing mechanism 13 effectively realizes the lifting and descending of the wiping and mopping piece 11 on the bottom of the cleaning main body 10, guarantees the automatic operation of the cleaning equipment 100, and further improves the structural stability and reliability of the cleaning equipment 100.

[0084] With reference to Figures 4 to 8In an embodiment of the present application, the cleaning main body 10 is provided with a stand column 15 connected to the bottom of the cleaning main body 10 and arranged at least at the edge of the bottom surface of the cleaning main body 10 close to the front end surface of the cleaning main body 10. The side of the stand column 15 facing the wiping and mopping member 11 is provided with a lifting guide rail 151, and the side of the wiping and mopping member 11 is provided with a guide protrusion 113 movably inserted into the lifting guide rail 151.

[0085] It can be understood that, by arranging the stand column 15 on the bottom of the cleaning main body 10, the cleaning main body 10 can be supported and fixed by the stand column 15 when moving to the surface of the building stairs 200, so as to ensure the lifting of the wiping and mopping member 11 on the surface of the stairs 200 to realize the cleaning of the stairs 200 by the cleaning equipment 100 and the avoidance of the wiping and mopping member 11 to the support unit 30. The stand column 15 can be arranged around the edge or corner of the bottom surface of the cleaning main body 10, or at least arranged at the edge of the bottom surface of the cleaning main body 10 close to the front end surface of the cleaning main body 10, so that the cleaning main body 10 can better keep the center of gravity at the front end of the cleaning equipment 100, and ensure that the moving mechanism 50 can more stably and reliably move the support unit 30 on the stairs 200 step by step, and ensure the automatic operation of the cleaning equipment 100. At the same time, universal wheel sets can also be arranged on the surface of the stand column 15 opposite to the cleaning main body 10, so that the cleaning equipment 100 can move laterally on the surface of the stairs 200 or move on the horizontal plane through the universal wheel sets on the cleaning main body 10, further ensuring the automatic operation of the cleaning equipment 100 and improving the structural reliability and stability of the cleaning equipment 100.

[0086] Secondly, by arranging the lifting guide rail 151 on the side of the stand column 15 facing the wiping and mopping member 11, the guide protrusion 113 of the wiping and mopping member 11 can be inserted into the lifting guide rail 151, so that the wiping and mopping member 11 can be limited and fixed by the lifting guide rail 151 during the lifting of the wiping and mopping member 11, avoiding the wiping and mopping member 11 from deviating along the length direction of the cleaning main body 10 when lifting on the bottom of the cleaning main body 10, ensuring the stable lifting of the wiping and mopping member 11 and further improving the overall structural stability and reliability of the cleaning equipment 100.

[0087] Further, referring to Figure 4 , Figure 5 , Figure 6 and Figure 8 , in an embodiment of the present application, the lifting guide rail 151 is arranged obliquely, and the distance between the lifting guide rail 151 and the front end surface of the cleaning main body 10 gradually increases from bottom to top along the height direction.

[0088] In the embodiment, by inclining the lifting guide rail 151 and gradually increasing the distance between the lifting guide rail 151 and the front end surface of the cleaning main body 10 in the height direction from bottom to top, the lifting guide rail 151 has a certain inclined guiding effect, so that the wiping and mopping piece 11 can better deviate a certain distance in the front-back direction during lifting, so that the wiping and mopping piece 11 can better move forward to clean the surface of the stairs 200 more comprehensively when it is required to lower the cleaning main body 10 to clean the surface of the stairs 200. When the scraping piece 315 moves to scrape the wiping and mopping piece 11, the inclined guiding effect of the lifting guide rail 151 can be used to move the wiping and mopping piece 11 backward when it is lifted so that the front end surface of the wiping and mopping piece 11 is not in the same plane as one side of the stand column 15, thereby facilitating the avoidance of interference between the supporting unit 30 and the stand column 15, which has a certain probability of causing the scraping piece 315 to be unable to completely scrape the wiping and mopping piece 11, better achieving the comprehensive cleaning of the wiping and mopping piece 11 by the scraping piece 315, further improving the self-cleaning effect of the cleaning equipment 100, improving the structural reliability and practicality of the cleaning equipment 100, and meeting the use requirements of users.

[0089] With reference to Figure 7 In an embodiment of the present application, the side of the supporting unit 30 opposite to the cleaning main body 10 is provided with a walking device 311.

[0090] In the embodiment, the walking device 311 is arranged at the bottom of the support unit 30, and the walking device 311 is used to drive the support unit 30 and the cleaning main body 10 to move in the horizontal direction. When the cleaning device 100 moves to the surface of each stair 200, the walking device 311 is used to drive the cleaning device 100 to move along the length direction of the stair 200, so that the cleaning mop 11 can clean the stair 200. The walking device 311 is used to drive the cleaning device 100 to move on each floor and the corner platform of the stair 200, so that the cleaning device 100 can move autonomously to clean, and the automation operation of the cleaning device 100 is improved, and the structural reliability and stability of the cleaning device 100 are improved. The walking device 311 can include two sets of walking wheels that are used to drive the support unit 30 to move in the front-back direction and the left-right direction on the surface of the stair 200, respectively. Alternatively, the walking device 311 can include a universal wheel set that can move in multiple directions on the horizontal plane. The cleaning device 100 can move in multiple degrees of freedom in the building autonomously, the autonomous movement effect of the cleaning device 100 is improved, and the practicality and structural reliability of the cleaning device 100 are improved. The driven wheel set or the movable wheel set is arranged at the bottom of the cleaning main body 10, so that the cleaning device 100 can move on the horizontal plane by using the wheel set at the bottom of the cleaning main body 10, and the cleaning main body 10 is prevented from interfering with the movement of the cleaning device 100 when the support unit 30 moves on the horizontal plane, and the structural reliability and stability of the cleaning device 100 are improved.

[0091] With reference to Figures 4 to 8 In one embodiment of the present application, the cleaning main body 10 is provided with a containing cavity 17, and the cleaning main body 10 is provided with an inlet and outlet that communicates with the containing cavity 17.

[0092] In the embodiment, by arranging the accommodating cavity 17 in the interior of the cleaning main body 10, the cleaning main body 10 can form a certain bearing accommodating structure, which is beneficial for the cleaning main body 10 to bear certain articles, such as cleaning robots for cleaning the building floor, during the movement of the cleaning main body 10 on the building stairs 200, so that the user can also carry the cleaning robot for cleaning the floor to other floors for cleaning by using the cleaning equipment 100, which solves the need for multiple cleaning robots for multi-storey buildings, better meets the use demand of the user, and further improves the practicability and structural reliability of the cleaning equipment 100.
