[0025] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0026] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the process, method, commodity or device including the elements.

[0027] See also Figures 1 to 6 The cleaning device 1 provided in the embodiment of the present application includes a host 100 and a cleaning device 200. The host 100 is provided with a water supply system 110 and a recovery system 120, and can be docked by the cleaning device 200, wherein the water supply system 110 is used to supply liquid, and the recovery system 120 is used to recover liquid.

[0028] The cleaning device 200 includes a device body 20 and a cleaning component 30. The device body 20 may be, but is not limited to, a shell 21 and an outer cover 22. The shell 21 is combined with the outer cover 22, and has a storage space in the shell 21 for installing at least a portion of the cleaning component 30 or other parts. The top of the outer cover 22 is provided with an opening 221 and a plurality of through holes 222 surrounding the opening 221, and the bottom is provided with a cleaning port 23. For the convenience of understanding and explanation, in the embodiment of the present application, the direction in which the shell 21 and the outer cover 22 overlap each other is used as the projection direction of the device body 20 (which can also be regarded as the projection direction of the outer cover 22), and in each implementation, the top, top surface and top end of each component are the parts of each component facing the side of the shell 21 in this projection direction, and the bottom, bottom surface and bottom end of each component are the parts of each component facing away from the side of the shell 21 in this projection direction, which are described first.

[0029] The outer cover 22 includes a substrate S and a side plate P. An opening 221 and a plurality of through holes 222 are provided on the substrate S. The side plate P is connected to the periphery of the substrate S, and forms a cavity around the substrate S, and a cleaning port 23 connected to the cavity and open to the outside is formed on a side away from the substrate S. In addition, a sewage discharge channel 24 is provided in the housing 21. One end of the sewage discharge channel 24 is connected to the opening 221 on the outer cover 22, and the other end is connected to the external environment, so as to be connected to the recovery system 120 of the host 100.

[0030] The cleaning assembly 30 includes a brush plate 31 and a water distribution plate 32. The brush plate 31 is arranged in the cleaning port 23 of the device body 20, and a sewage suction port 313 is arranged at a corresponding central position thereof. The sewage suction port 313 is connected to the recovery system 120 through the sewage discharge channel 24. The water distribution plate 32 is provided with a water inlet 321 and a plurality of water outlets 322. The water inlet 321 is connected to the water supply system 110 to receive the liquid supplied by the water supply system 110. The plurality of water outlets 322 are connected to the cleaning port 23 and are arranged around the periphery of the brush plate 31 to guide the liquid to flow to the cleaning port 23.

[0031] It is worth noting that when the brush disc 31 is disposed in the cavity of the outer cover 22, the brush disc 31 has a predetermined thickness on the substrate S of the outer cover. At the same time, the outer peripheral surface of the brush disc 31 and the side wall in the cavity (i.e., the surface of the side plate P) are separated by a predetermined distance, so that an annular groove T surrounding the edge of the cavity is formed between the outer peripheral surface of the brush disc 31 and the substrate S and the side plate P of the outer cover. The multiple water outlets 322 of the water distribution disc 32 are located in the annular groove T in the projection direction of the outer cover 22 and are arranged at intervals. In this way, the liquid flowing out of the multiple water outlets 322 can flow into the cavity along the side plate P more concentratedly and accurately, and flow toward the cleaning port 23, without splashing everywhere. At the same time, the liquid can also be evenly distributed on the brush 33 of the brush disc 31, and flow toward the sewage suction port 313 under the guidance of the brush 33.

[0032] In some embodiments of the present application, the cleaning device 200 further includes a driving assembly 40, which is disposed in the device body 20 and connected to the brush disc 31, for driving the brush disc 31 to rotate. In use, the user only needs to make the cleaning port 23 correspond to the surface of the object to be cleaned (such as a sofa or a carpet), and the object to be cleaned can be cleaned by rotating the brush disc 31. Among them, through the rotation of the brush disc 31, the liquid can be driven to move in the cleaning port 23, so that the cleaning assembly 30 can achieve the effect of brushing the object to be cleaned, and the liquid after brushing can be driven to flow toward the suction port 313, so as to be recovered by the recovery system 120. In this way, through the brushing of the brush disc 31, not only can the stains and impurities of the object to be cleaned be effectively removed, but also the liquid after brushing can be automatically recovered to avoid being retained on the object to be cleaned.

[0033] It should be noted that the liquid supplied by the water supply system 110 may be, but is not limited to, clean water, cleaning liquid or a combination thereof (for example, an appropriate cleaning liquid is selected according to the material characteristics of the object to be cleaned), and the liquid recovered by the recovery system 120 refers to the wastewater formed by the dirt mixed in the liquid after the object to be cleaned is scrubbed. For example, when the liquid is clean water, the dirt on the object to be cleaned can be effectively removed by the brushing of the brush plate 31; when the liquid is a mixture of cleaning liquid and clean water, the stains on the object to be cleaned can be further decomposed or dissolved, making it easier to clean the brush plate 31.

[0034] It is understandable that the sewage generated by the cleaning component 30 during the cleaning process, after being driven by the brush plate 31 and gathered at the sewage suction port 313, can be pumped to the recovery system 120 through the sewage discharge channel 24 to ensure effective recovery of the sewage and prevent the sewage from being retained on the object to be cleaned and affecting the cleaning effect. For example, the recovery system 120 includes an air pump to generate suction in the sewage discharge channel 24 so that the sewage can be quickly pumped to the recovery system 120.

[0035] In some embodiments of the present application, the brush plate 31 includes a plate body 311 and a cover body 312, and the cover body 312 is detachably arranged on the plate body 311. The sewage outlet 313 on the brush plate 31 forms a first sewage suction outlet 3131 and a second sewage suction outlet 3132 that are connected on the plate body 311 and the cover body 312, respectively. The first sewage suction outlet 3131 is arranged at the center of the plate body 311 and passes through the top and bottom surfaces of the plate body 311. A plurality of brushes 33 are arranged on the bottom surface of the plate body 311 and surround the first sewage suction outlet 3131.

[0036] The top of the cover 312 is provided with a shaft 3121 and a groove 3122, and a coupling portion 314 is provided at the bottom of the cover 312. The shaft 3121 is connected to the drive assembly 40, and the groove 3122 surrounds the outer periphery of the shaft 3121 and corresponds to the sewage discharge channel 24. The setting position of the coupling portion 314 on the cover 312 corresponds to the groove 3122, so that the coupling portion 314 protrudes from the bottom of the cover 312 and extends toward the first sewage suction port 3131 of the disk 311. The second sewage suction port 3132 is provided on the coupling portion 314 and is connected to the groove 3122, wherein the number of the second sewage suction ports 3132 can be one or more. This embodiment is illustrated by taking a plurality of second sewage suction ports 3132 arranged at intervals and arranged around the shaft 3121 along the groove 3122 as an example, but is not limited thereto.

[0037] In the assembly of the disk body 311 and the cover body 312, the cover body 312 can be assembled with the first sewage suction port 3131 of the disk body 311 by the joint portion 314, for example, by snap-fitting, or by providing matching internal and external threads on the outer circumference of the joint portion 314 and the inner edge of the first sewage suction port 3131, so as to connect them in a mutually tightened manner. Alternatively, they can be locked and fixed by fixing components such as screws or bolts, and the cover body 312 is further locked to the driving component 40 by the fixing component. At this time, the second sewage suction port 3132 and the first sewage suction port 3131 are coaxially arranged, overlap each other in the projection direction of the device body 20, and are connected to each other (such as Figure 5 shown).

[0038] See also Figures 1 to 4In the embodiment of the present application, a plurality of brushes 33 are arranged on the bottom surface of the disk 311. In some embodiments, the plurality of brushes 33 may also have different external structures, for example, the brush 33 may include a plurality of brush heads 33A or a plurality of wiper strips 33B, or a combination of a plurality of brush heads 33A and a plurality of wiper strips 33B. Each wiper strip 33B includes a comb tooth portion 331 and a wiper portion 332, wherein the comb tooth portion 331 has a comb tooth structure arranged in an array, so that its surface is a rough surface, and the surface of the wiper portion 332 is a smooth surface with a straight outer edge. For example, the wiper portion 332 may be a hard plastic formed in one piece, or a soft glue is provided on the surface, depending on the surface material of the object to be cleaned. For example, the hard plastic wiper portion 332 is suitable for scraping off water on the surface of a carpet, while the wiper portion 332 provided with a soft glue is suitable for a non-carpet plane, for example, scraping off water on a tile or floor for suction, etc., but is not limited thereto.

[0039] A plurality of wiper strips 33B protrude outward from the bottom surface of the plate body 311 and surround the first sewage suction port 3131, and a water collection port C is formed on the plate body 311, so that the first sewage suction port 3131 is located in the water collection port C and communicated with it. In this embodiment, wiper strips 33B are respectively arranged on the left and right sides of the first sewage suction port 3131, and one end of the comb tooth portion 331 and the wiper portion 332 of each wiper strip 33B is connected to each other, and the connection position corresponds to the first sewage suction port. The ends of the comb tooth portion 331 and the wiper portion 332 that are away from each other, that is, the ends of the wiper strips 33B on the opposite sides in the length direction, respectively extend into the annular groove T. At this time, the gap between the ends of the two wiper strips 33B located on both sides of the first sewage suction port 3131 constitutes a suction nozzle structure V, so that the water collection port C formed by the two wiper strips 33B is connected to the annular groove T through the suction nozzle structure V. In this way, a good water supply and scrubbing effect can be achieved, and the sewage can be gathered and scraped toward the sewage suction port 313. When the driving assembly 40 drives the brush plate 31 to rotate, it can drive the multiple comb teeth 331 to brush the object to be cleaned (repeatedly rub to effectively clean the dirt), and drive the multiple scraping parts 332 to move the sewage generated during the scrubbing process toward the sewage suction port 313.

[0040] Specifically, in the application scenario of the present application, when the cleaning device 200 performs fixed-point cleaning within the working range, the cleaning port 23 on the outer cover 22 can be attached to the surface to be cleaned, and water can be sprayed toward the cleaning port 23 through multiple water outlets 322 surrounding the outer periphery of the brush plate 31. The water sprayed from the multiple water outlets 322 is evenly sprayed on the area of ​​the surface to be cleaned corresponding to the annular groove T. At the same time, the two wiper strips 33B on the brush plate 31 extend to the suction nozzle structure V in the annular groove T, and the water is sucked toward the water collection port C located in the middle. At this time, the water sprayed on the surface to be cleaned corresponding to the annular groove V is guided by the suction force of the water collection port C and flows to the suction port 313 located in the center of the brush plate in the water collection port C. The flowing water can wet the surface to be cleaned corresponding to the brush plate 31, thereby improving the cleaning effect. On the other hand, the water flowing in the water collection port C will also be evenly wiped on the surface to be cleaned by the rotating wiper strip 33B, and the surface to be cleaned will be evenly wetted. Through the above means, the liquid sprayed from the multiple water outlets 322 can completely wet the area to be cleaned covered by the outer cover 22, thereby achieving a better cleaning effect.

[0041] In addition, in some other embodiments of the present application, the plurality of comb-tooth portions 331 and the plurality of wiper portions 332 between two adjacent wiper strips 33B are arranged in a staggered manner (eg, Figure 3 As shown in the figure, when the brush plate 31 rotates, the brushing range of the multiple comb teeth 331 covers the cleaning port 23. Through the staggered arrangement, when the comb teeth 331 first brush the object to be cleaned, the sewage enters the water collection port C between the two wiper strips 33B through the gap between the comb teeth structure, and the wiper 332 can then use its smooth edge to move the brushed sewage to the sewage suction port 313. Figure 3 As shown, when the brush plate 31 rotates clockwise, the comb teeth 331 is in front and the wiper 332 is in the back. In the rotation direction of the brush plate 31, the comb teeth 331 combs the cleaning objects, and the sewage can enter the first sewage suction port 3131 through the gaps between the comb teeth structures. The wiper 332 located behind the comb teeth 331 scrapes the sewage generated by the cleaning objects through its straight outer edge and collects the sewage in the water collection port C to reduce the sewage from escaping and the large amount of sewage remaining on the surface of the cleaning objects, and the sewage collected in the water collection port C is sucked away by the sewage suction port 313 under the action of vacuum pressure. In this way, the cycle process of continuous water supply by the water supply system 110 and instant sewage pumping by the recovery system 120 can not only achieve an effective brushing effect on the cleaning objects, but also has the function of automatically recovering sewage.

[0042] The following is an explanation of the configuration of other components in the cleaning device 200 provided in the embodiment of the present application. In some embodiments of the present application, the drive assembly 40, the water distribution plate 32 and the sewage channel 24 are respectively arranged in the shell 21 of the device body 20, so that the groove 3122 on the brush plate 31 corresponds to the opening 221, the drive assembly 40 is connected to the brush plate 31 through the opening 221, and the multiple water outlets 322 of the water distribution plate 32 correspond to the multiple through holes 222. In some embodiments, the shell 21 includes an upper shell 211 and a lower shell 212, and the upper shell 211 and the lower shell 212 can be fixed by means of, but not limited to, snap-fitting or screw locks. Among them, the drive assembly 40 and the sewage channel 24 can be assembled in the upper shell 211 or the lower shell 212, and the outer cover 22 can be fixed to the lower shell 212 by means of, but not limited to, snap-fitting or screw locks. It is understandable that, through the above-mentioned assembly method, the user can quickly disassemble and assemble the cleaning device 200 for inspection or replacement, thereby effectively improving the efficiency of maintenance.

[0043] In addition, in some other embodiments of the present application, the water distribution tray 32 is an annular structure and is arranged on the outer cover 22 (for example, fixed to the outer cover 22 by means of screw locks and located in the lower shell 212), and the water distribution tray 32 is provided with a plurality of nozzles 323. Among them, a plurality of water outlets 322 are respectively arranged on the plurality of nozzles 323, and the plurality of nozzles 323 protrude from the surface of the water distribution tray 32 facing the outer cover 22, and the water inlet 321 is arranged on the surface of the water distribution tray 32 facing away from the outer cover 22. The inner layer of the water distribution tray 32 may have an annular multi-layer water distribution channel, which respectively connects the water inlet 321 and the plurality of water outlets 322. When the water distribution tray 32 is arranged on the outer cover 22, the plurality of nozzles 323 pass through the plurality of through holes 222 correspondingly, and the water outlet 322 faces the cleaning port 23. For example, the water supply system 110 is connected to the water inlet 321 through the water inlet pipe 111 , so that the liquid can enter the water inlet 321 through the water inlet pipe 111 , and pass through the multi-layer water distribution channels and be evenly sprayed from each water outlet 322 to the cleaning port 23 .

[0044] It is worth mentioning that in this embodiment, multiple nozzles 323 surround the sewage suction port 313 in the projection direction. Through such a configuration, the liquid can be sprayed from the periphery of the sewage suction port 313 to the cleaning port 23, or flow from the inner wall of the outer cover 22 to the cleaning port 23 (to prevent the liquid sprayed by the nozzle 323 from approaching the sewage suction port 313 and being directly sucked into the recovery system 120), so as to cooperate with the comb teeth 331 to brush the object to be cleaned, and after cleaning and combing, the sewage on the surface of the object to be cleaned is scraped to the center of the sewage suction port 313 through the multiple scraping parts 332, and can be sucked into the recovery system 120 (the liquid spraying direction and the recovery direction are as shown in FIG. Figure 5 The purpose of automatic scrubbing and recycling is achieved.

[0045] In some embodiments of the present application, the driving assembly 40 includes a motor 41 and a bracket 42. The motor 41 is disposed on the bracket 42, and the bracket 42 can be assembled and connected to the outer cover 22. The bracket 42 is provided with a connected alignment hole 421 and a docking port 422, the alignment hole 421 corresponds to the opening 221 of the outer cover 22, the alignment hole 421 is eccentrically arranged relative to the center of the brush plate 31, and will not rotate with the rotation of the brush plate 31, the sewage discharge channel 24 is engaged with the docking port 422, so that the motor 41 is connected to the brush plate 31 through the alignment hole 421 and the opening 221, and the sewage suction port 313 and the groove 3122 are connected to the sewage discharge channel 24 through the connected alignment hole 421 and the docking port 422.

[0046] In some embodiments, the cleaning device 200 further includes an air duct 25, and the sewage discharge channel 24 is disposed in the air duct 25. The air duct 25 is detachably disposed in the housing 21, and the sewage discharge channel 24 forms an inlet 241 and an outlet 242 at two opposite ends of the air duct 25, respectively. Among them, the inlet 241 is connected to the docking port 422, and the outlet 242 is connected to the recovery system 120, so that the sewage suction port 313 can be connected to the recovery system 120. It is worth mentioning that in this embodiment, the caliber of the inlet 241 of the sewage discharge channel 24 is smaller than the caliber of the outlet 242, and the pressure difference between the inlet 241 and the outlet 242 effectively improves the sewage suction efficiency.

[0047] In addition, the host 100 may also be provided with a control unit 130. The control unit 130 is electrically connected to the drive assembly 40, the water supply system 110 and the recovery system 120, respectively, to drive the water supply system 110, the recovery system 120 and the drive assembly 40 to operate, so that the drive assembly 40 drives the brush plate 31 to rotate, the water supply system 110 delivers liquid to the water outlet 322, and the recovery system 120 generates suction in the sewage discharge channel 24, guides the liquid into the sewage suction port 313, and transmits it to the recovery system 120 through the sewage discharge channel 24, which has the advantages and functions of automatic scrubbing and automatic sewage recovery. For example, the control unit 130 is provided with an operation interface or a power switch for the user to start and shut down.
