[0003] At present, the cleaning device can include a main machine and a brush structure connected with the main machine, the main machine is connected with the brush structure through a connecting rod and is rotatably arranged relative to the brush structure. The main machine has a suction assembly and a sewage tank inside, the brush structure is used for dry or wet mopping of the surface to be cleaned (such as the ground), and the negative pressure generated by the suction assembly sucks the sewage on the brush structure into the sewage tank.

[0004] However, in order to avoid the sewage of the brush structure from flowing back to the inside of the main machine and causing damage, the height of the main machine needs to be always higher than that of the brush structure, which restricts the use occasions of the cleaning device. SUMMARY

[0005] The embodiments of the present application provide a brush structure and a cleaning device, which are convenient to clean and have high adjustment freedom.

[0006] In a first aspect, the present application provides a brush structure applied to a cleaning device, the brush structure comprising a housing, a rolling brush assembly and a water circulation assembly, the rolling brush assembly comprising a rolling brush, the rolling brush being rotatably arranged in the housing and partially exposed at the bottom of the housing;

[0007] The water circulation assembly comprises a water spraying unit and a sewage recovery unit, both of which are arranged on the housing, the water spraying unit comprising a clean water tank, and the water spraying unit being configured to spray the cleaning liquid in the clean water tank to the rolling brush, the sewage recovery unit comprising a water collecting member and a sewage tank, the water collecting member being communicated with the sewage tank and being configured to collect the sewage on the rolling brush to the sewage tank.

[0008] In this way, the height of the clean water tank and the sewage tank is always lower than or equal to the height of the main machine, so the sewage cannot flow into the inside of the main machine, and the cleaning device can maintain normal work in various postures. Therefore, the brush structure and the cleaning device can work in various occasions and postures, and are convenient and flexible to use.

[0009] In an optional embodiment, the clean water tank and the sewage tank are arranged side by side on the housing in the axial direction of the rolling brush.

[0010] In an alternative embodiment, the clean water tank and the dirty water tank are symmetrically arranged relative to the center line of the width direction of the housing. In this way, the mop structure is more balanced on both sides of the width direction of the housing, and the counterweight is more reasonable, thereby facilitating the user's manipulation of the mop structure and the advancing movement of the mop structure itself.

[0011] In an alternative embodiment, the clean water tank and the dirty water tank have a height dimension in the vertical direction that is smaller than the dimensions in other directions. In this way, the clean water tank and the dirty water tank have a flat horizontal structure as a whole, so that the clean water tank and the dirty water tank do not increase the overall height of the mop structure too much, effectively ensuring the convenience of the mop structure when cleaning.

[0012] In an alternative embodiment, at least one of the clean water tank and the dirty water tank is detachably connected to the housing. In this way, it is convenient to add cleaning liquid when the clean water tank is empty, or to pour out the dirty water in the dirty water tank when it is full.

At this time, the entire mop rolling brush is located within the range covered by the tank opening of the water collecting tank, thereby enabling the water collecting tank to have a better collection effect.

[0019] In an alternative embodiment, the water collecting tank is inclined towards the side away from the rolling brush, so that the height of the tank opening is greater than the height of the tank bottom of the water collecting tank. In this way, the water collecting and storage effect of the water collecting tank can be improved.

[0020] In a possible implementation, the sewage tank has a water inlet, and the water inlet is in communication with the bottom of the water collecting groove.

[0021] In a possible implementation, the sewage recovery unit further comprises a suction pump, the suction pump is in communication with the water inlet, and is configured to suck the sewage on the roller brush into the sewage tank. In this way, the suction pump can suck the sewage on the roller brush into the sewage tank by the suction force of the suction pump itself.

[0022] In a possible implementation, the sewage tank has an air outlet, and the air outlet is configured to extract air outward to form a negative pressure in the sewage tank. In this way, the sewage can be sucked into the sewage tank by the negative pressure generated by other structures or components outside the floor brush structure.

[0023] In a possible implementation, the shell has a suction port air duct, the suction port air duct is configured to be in communication with a dust collection main machine of the cleaning device, and the suction port air duct is in communication with the air outlet. In this way, most of the suction force of the dust collection main machine of the cleaning device is used to suck external dirt, and a small part of the suction force of the suction port air duct acts on the sewage tank through the air extraction hole to extract air in the sewage tank.

[0042] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application.

[0043] Firstly, it should be understood by those skilled in the art that the embodiments are only used for explaining the technical principles of the present application, and are not intended to limit the protection scope of the present application. Those skilled in the art can make adjustments according to the needs in order to adapt to specific application occasions.

[0044] Secondly, it should be noted that, in the description of the present application, the terms indicating the direction or positional relationship such as "inner", "outer" and the like are based on the direction or positional relationship shown in the drawings, which is only for the convenience of description, and does not indicate or imply that the device or member must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0045] In addition, it should be noted that, in the description of the present application, unless otherwise explicitly specified and limited, the terms "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be the communication inside two members. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0046] In the description of the present specification, the description referring to the terms "one embodiment", "some embodiments", "illustrative embodiment", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present disclosure. In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0047] Currently, the cleaning device includes a main machine and a floor brush structure connected with the main machine, the floor brush structure is used for dry wiping or wet wiping a surface to be cleaned (for example, a floor); and the main machine is connected with the floor brush structure through a connecting rod or the like, and is rotatably arranged relative to the floor brush structure, so that a user holds or manipulates the main machine to realize cleaning operation, and can raise or lower the height of the main machine to avoid furniture and other obstacles in the cleaning process. Among them, the main machine generally has a suction assembly, the suction assembly and the floor brush structure are communicated, so as to use the negative pressure generated by the suction assembly to perform dust collection operation, or to suck the sewage on the floor brush structure into the sewage tank arranged in the main machine.

[0048] However, when the height of the main machine is too low, for example, the height of the main machine is lower than that of the floor brush structure, the sewage in the floor brush structure will flow back to the inside of the main machine, thereby damaging the main machine. Therefore, the user needs to maintain a higher height posture of the main machine during the cleaning process.

[0049] Therefore, the present application provides a floor brush structure and a cleaning device, the shell of the floor brush structure is provided with a clean water tank and a sewage tank, and the clean water tank provides cleaning liquid to the floor brush structure, and the sewage tank can collect sewage on the floor brush structure. In this way, clean water and sewage are always sprayed and recovered at the floor brush structure, and the collected sewage no longer flows to the main machine of the cleaning device, so that the main machine of the cleaning device does not need to maintain a higher height posture during cleaning operation, but can maintain a lying posture, and the use of the cleaning device is more free and convenient.

[0050] The structure and various possible implementation forms of the floor brush structure and the cleaning device provided by the present application are described in detail in combination with the specific embodiments.

[0051] Figure 1 is a structural schematic diagram of the floor brush structure provided by the embodiment of the present application. Figure 2 is Figure 1 is a structural schematic diagram of the floor brush structure in the figure when the roller brush assembly and the shell are in a disassembled state. Figure 3 is Figure 1 is an exploded schematic diagram of the floor brush structure in the figure. As shown in Figures 1 to 3 The floor brush structure 100 provided by the present application is applied to a cleaning device, and includes a shell 110, a roller brush assembly 120, and a water circulation assembly and other different components.

[0052] Among them, the roller brush assembly 120 includes a roller brush 121, the roller brush 121 is rotatably arranged in the shell 110, and part of the roller brush 121 is exposed at the bottom of the shell 110, so as to be used for contacting the ground and generating rotary motion relative to the shell 110, thereby realizing cleaning operation.

[0053] The water circulation assembly includes a water spraying unit 130 and a sewage recovery unit 140, both of which are arranged on the shell 110. The water spraying unit 130 includes a clean water tank 131, and is configured to spray the cleaning liquid in the clean water tank 131 to the roller brush 121. The sewage recovery unit 140 includes a water collecting member and a sewage tank 141, the water collecting member is communicated with the sewage tank 141, and is configured to collect the sewage on the roller brush 121 to the sewage tank 141.

[0054] Specifically, the floor brush structure 100 is mainly applied to household cleaning devices such as vacuum cleaners and mops, to clean the ground. The roller brush 121 in the floor brush structure 100 can be at least two, and part of the roller brush 121 can be a mop roller brush 121a. The mop roller brush 121a rotates relative to the shell 110, thereby performing the mopping operation. When performing the mopping operation, the surface of the mop roller brush 121a needs to be soaked with liquid, so the water circulation assembly can spray cleaning liquid to the mop roller brush 121a, thereby realizing the wetting of the mop roller brush 121a. During the mopping operation performed by the mop roller brush 121a, the sewage recovery unit 140 in the water circulation assembly can also collect the sewage on the mop roller brush 121a to keep the surface of the mop roller brush 121a clean, so that the mop roller brush 121a can be cleaned in real time by the water circulation assembly. The surface of the mop roller brush 121a can be attached with a layer of soft material, such as wool or bristles. During use, the wool or bristles clean the ground and absorb the sewage on the ground.

[0055] In addition, the plurality of roller brushes 121 can also include a dry suction roller brush 121b, which is configured to roll up dust, particulate matter and other impurities on the ground to clean dry garbage.

[0056] When the water circulation assembly sprays or recovers and collects the cleaning liquid or sewage on the mop roller brush 121a and other roller brushes, in order to store the cleaning liquid or sewage, the water spraying unit 130 in the water circulation assembly includes a clean water tank 131, and the sewage recovery unit includes a sewage tank 141. The clean water tank 131 and the sewage tank 141 are arranged on the shell 110 of the floor brush structure 100. Since the roller brush 121 in the floor brush structure 100 always contacts the ground, the clean water tank 131 and the sewage tank 141 always have a short distance from the ground with the floor brush structure 100.

[0057] In the prior art, the sewage storage and other components of the cleaning device are generally arranged on the main machine. If the sewage flows into the interior of the main machine, it may cause short circuit of the electrical control elements in the interior of the main machine, or cause the sewage to mix with the dust, hair and other dirt of the suction assembly in the interior of the main machine, and cause a difficult-to-clean condition. In the floor brush structure 100 in the embodiment, since the clean water tank 131 and the sewage tank 141 are always at a height close to the ground with the floor brush structure 100, no matter how the user adjusts the attitude of the cleaning device (i.e. adjusts the height of the main machine relative to the floor brush structure 100), the height of the clean water tank 131 and the sewage tank 141 is always lower than or equal to the height of the main machine, and the distance between the sewage tank 141 and the main machine of the cleaning device is also relatively far. Therefore, the sewage cannot flow into the interior of the main machine, and the working of the main machine of the cleaning device is not easily affected by the sewage, so that the cleaning device can maintain normal working in various attitudes. Therefore, the floor brush structure 100 and the cleaning device can work in various occasions and attitudes, and are convenient and flexible to use.

[0058] In order to have a large liquid storage capacity, the clean water tank 131 and the sewage tank 141 can have a large size. In order to facilitate the arrangement of the clean water tank 131 and the sewage tank 141, in an optional embodiment, the clean water tank 131 and the sewage tank 141 can be arranged side by side on the shell 110 in the axial direction of the rolling brush 121. At this time, since the floor brush structure 100 has a large size in the axial direction of the rolling brush 121, there is a relatively sufficient space to arrange the clean water tank 131 and the sewage tank 141, so that the clean water tank 131 and the sewage tank 141 have a large size and volume, which is beneficial to the long-time working and continuous cleaning of the floor brush structure 100.

[0059] In the cleaning work, the user needs to manipulate the floor brush structure 100 to travel relative to the ground to clean different areas. In order to facilitate the user to operate, optionally, the clean water tank 131 and the sewage tank 141 can be symmetrically arranged relative to the middle line of the width direction of the shell 110. Since the connecting rod and other structures of the cleaning device are generally connected to the middle line position of the shell 110 in the width direction, the clean water tank 131 and the sewage tank 141 are symmetrically arranged relative to the middle line, the structure on both sides of the shell 110 in the width direction is balanced, and the counterweight is reasonable, so as to facilitate the user to manipulate the floor brush structure 100 and the floor brush structure 100 to move.

[0060] The floor brush structure 100 needs to always contact the ground during cleaning, and accordingly, the floor brush structure 100 needs to have a relatively low height and a relatively compact size in order to facilitate the cleaning operation. At this time, as an optional structure, the height of the clean water tank 131 and the sewage tank 141 in the vertical direction is smaller than the size in other directions.

[0061] For example, the water tank 131 and the sewage tank 141 are square as a whole, the width direction of the water tank 131 and the sewage tank 141 can be consistent with the width direction of the shell 110 of the floor brush structure 100, the length direction of the water tank 131 and the sewage tank 141 is along the front-rear direction of the floor brush structure 100, and the height dimension of the water tank 131 and the sewage tank 141 in the vertical direction is smaller than the length direction or the width direction. In this way, the water tank 131 and the sewage tank 141 are in a flat horizontal structure as a whole, so that when the water tank 131 and the sewage tank 141 are arranged on the shell 110, the overall height of the floor brush structure 100 is not increased too high, and the convenience of the floor brush structure 100 during cleaning is effectively ensured.

[0062] In order to realize the installation of the water tank 131 and the sewage tank 141 on the shell 110, the water tank 131 and the sewage tank 141 can have various different arrangement modes on the shell 110, for example, the water tank 131 and the sewage tank 141 can be integrated with the shell 110, or the water tank 131 and the sewage tank 141 can be embedded in the shell 110.

[0063] In order to facilitate the filling or pouring of the liquid, in an optional embodiment, at least one of the water tank 131 and the sewage tank 141 can be detachably connected with the shell 110. In this way, the water tank 131 or the sewage tank 141 can be separated from and removed from the shell 110, so as to facilitate the filling of the cleaning liquid when the water tank 131 is empty, or the sewage is poured out when the sewage tank 141 is full of sewage.

[0064] Specifically, the water tank 131 and the sewage tank 141 are detachably connected with the shell 110. The outer top wall of the shell 110 can be provided with a mounting groove, the shape of the mounting groove is matched with the shape of the water tank 131 and the sewage tank 141, and the water tank 131 and the sewage tank 141 can be embedded in the corresponding mounting groove to realize the cooperative installation with the shell 110.

[0065] In addition, it should be noted that the water tank 131 and the sewage tank 141 can also be detachably connected with the shell 110 through buckles or other types of quick-release structures, as long as the water tank 131 and the sewage tank 141 can be conveniently taken and placed, and can be reliably fixed on the shell 110.

[0066] In order to let the water spraying unit 130 spray the cleaning liquid to the rolling brush 121, correspondingly, as an optional water spraying unit structure, the water spraying unit 130 further comprises a water spraying member 132, which is in communication with the clean water tank 131 and is used for spraying the cleaning liquid to the rolling brush 121. Wherein, the water spraying member 132 can be fixedly connected with the shell 110 of the floor brush structure 100, or can be detachably mounted on the shell 110. The water spraying member 132 can be in communication with the clean water tank 131 through a pipe such as a hose.

[0067] Wherein, Figure 4 is a structure diagram of a water spraying member in the floor brush structure provided by the embodiment of the present application. As shown in Figure 4 Optionally, the water spraying member 132 extends along the axial direction (Y direction in the figure) of the rolling brush 121, and a plurality of water spraying openings 1321 facing the rolling brush 121 are formed on the water spraying member 132, and the plurality of water spraying openings 1321 are arranged in the axial direction of the rolling brush 121. By arranging the plurality of water spraying openings 1321 in the axial direction of the rolling brush 121, the water spraying member 132 can spray the cleaning liquid such as water to different parts in the axial direction of the rolling brush 121, so that each part of the rolling brush 121 can be uniformly wetted by the cleaning liquid.

[0068] In the specific implementation, in order to normally spray the cleaning liquid, the water spraying unit 130 further comprises a driving pump 133 connected between the water spraying member 132 and the clean water tank 131, so as to spray the cleaning liquid in the clean water tank 131 out through the water spraying member 132.

[0069] As can be easily understood by those skilled in the art, in addition to the above-mentioned arrangement mode connected between the water spraying member 132 and the clean water tank 131, the driving pump 133 can also be directly connected to the clean water tank 131, so as to displace the cleaning liquid in the clean water tank 131 to the water spraying member 132 by spraying air flow into the clean water tank 131. It should be noted that at this time, the clean water tank 131 should have a sealed cavity to ensure the normal work of the driving pump 133.

[0070] In order to collect and recycle the sewage on the rolling brush 121, the sewage recycling unit 140 further comprises a water collecting member in addition to the sewage tank 141, which can be used to collect the sewage on the rolling brush 121 and transport the collected sewage into the sewage tank 141.

[0071] Specifically, when the rolling brush 121 in the floor brush structure 100, for example, the mopping rolling brush 121a rotates, the sewage on the mopping rolling brush 121a can be thrown into the water collecting member, or a scraper structure is arranged on the shell 110, the sewage on the mopping rolling brush 121a is scraped down by the scraper structure, and then is collected into the water collecting member to collect the sewage on the mopping rolling brush 121a.

[0072] Figure 5 is a cross-sectional view of a part of the water circulation assembly in the mop structure provided by an embodiment of the present application. Figure 6 is Figure 5 is a local enlarged view of A in Figure 5 and Figure 6 As shown in

[0073] In order to improve the collection efficiency of the water on the mop, the water collecting tank 142 is usually arranged at the lower part of the mop 121, and in an example, the water collecting tank 142 can be arranged at one side of the mop 121 and below the rotation axis of the mop 121. The water splashed or scraped off by the scraping plate structure on the mop 121 can be collected into the water collecting tank 142 under the action of gravity.

[0074] Optionally, the extension direction of the water collecting tank 142 is consistent with the axis of the mop 121, and the water collecting tank 142 extends at least to both ends of the mop 121. In this way, the edge of the water collecting tank 142 can be flush with the end of the mop 121, or extend to the outside of the end of the mop 121. At this time, the entire mop 121 is located within the range covered by the slot 1421 of the water collecting tank 142, so that the water collecting tank 142 has a better collection effect.

[0075] In order to improve the water collection and storage effect of the water collecting tank 142 and avoid the water entering the water collecting tank 142 from leaking out, in an optional structure, the water collecting tank 142 is inclined toward the side away from the mop 121, so that the height of the slot 1421 is greater than the height of the tank bottom 1422 of the water collecting tank 142.

[0076] In this way, the water collecting tank 142 is inclined as a whole, and the water entering the water collecting tank 142 flows downward along the tank wall from the slot 1421 and collects at the position of the tank bottom 1422, avoiding the backflow of the water out of the water collecting tank 142.

[0077] In order to suck the water into the water tank 141, the water recovery unit 140 can have various ways of sucking water, and the water sucking way of the water recovery unit 140 is further introduced below.

[0078] Figure 7 is a first structure schematic view of the water recovery unit in the mop structure provided by an embodiment of the present application. As shown in Figure 7As shown, in the first possible structure, the sewage can be sucked by the elements and structures inside the sewage recovery unit 140, at this time, the sewage tank 141 has a water inlet 1411, and the water inlet 1411 is communicated with the bottom 1422 of the water collecting groove 142. Correspondingly, the pump body can be arranged in the sewage recovery unit 140, and the pump body is used to suck the sewage into the sewage tank 141 through the water inlet.

[0079] Specifically, the sewage recovery unit 140 includes a suction pump 143, the suction pump 143 can be communicated with the water inlet 1411 through the first pipeline 1431, and the suction pump 143 and the bottom 1422 of the water collecting groove 142 can be communicated through the second pipeline 1432, so that the suction pump 143 can suck the sewage on the roller brush 121 into the sewage tank 141 through the suction force of the suction pump 143.

[0080] In this way, by arranging the suction pump 143 in the sewage recovery unit 140, the sewage can be sucked into the sewage tank 141 by the suction force of the suction pump 143 itself, without the help of external force of the main machine and other components, and the use is more convenient.

[0081] Figure 8 is a second structure schematic diagram of the sewage recovery unit in the floor brush structure provided by the embodiment of the application. As shown, Figure 8 In the second possible structure, the suction force can be provided by the main machine and other structures of the cleaning device to complete the extraction of the sewage. At this time, the sewage tank 141 has an air outlet 1412 in addition to the water inlet 1411, and the air outlet 1412 is configured to extract air outward to form negative pressure in the sewage tank 141. The air outlet 1412 can be communicated with other structures or components outside the floor brush structure 100, and the sewage can be sucked into the sewage tank 141 by the negative pressure generated by the other components.

[0082] When the suction force is provided by the main machine of the cleaning device, the main machine of the cleaning device is a main machine with a suction assembly, that is, a dust collection main machine; and the shell 110 has a suction port air duct 111, which is configured to be communicated with the dust collection main machine of the cleaning device, and the suction port air duct is communicated with the air outlet 1412.

[0083] When the cleaning device works, most of the suction force of the dust collection main machine is used to suck external dirt, and a small part of the suction force of the suction port air duct acts on the sewage tank 141 through the air outlet hole to extract the air in the sewage tank 141. After the air in the sewage tank 141 is extracted through the air outlet, the pressure in the sewage tank 141 is reduced, so that the suction force is generated at the water inlet 1411 to suck the sewage in the water collecting groove 142 connected with the water inlet 1411.

[0084] In addition, in order to guide the sewage on the rolling brush 121 to the water collecting tank 142, a scraping blade 144 can also be arranged above the water collecting tank 142. The end of the scraping blade 144 can be in contact with the surface of the rolling brush 121 and guide the sewage into the water collecting tank 142. In addition, a ground scraping blade 112 can also be arranged below the water collecting tank 142, and the ground scraping blade 112 is connected to the bottom of the shell 110.

[0085] Thus, the floor brush structure in the present application includes a shell, a rolling brush assembly and a water circulation assembly. The rolling brush assembly includes a rolling brush, which is rotatably arranged in the shell and partially exposed from the bottom of the shell. The water circulation assembly includes a water spraying unit and a sewage recovery unit, both of which are arranged on the shell. The water spraying unit includes a clean water tank, and is configured to spray the cleaning liquid in the clean water tank to the rolling brush. The sewage recovery unit includes a water collecting member and a sewage tank, and the water collecting member is communicated with the sewage tank and is configured to collect the sewage on the rolling brush to the sewage tank. Thus, the height of the clean water tank and the sewage tank is always lower than or equal to the height of the main machine, so that the sewage cannot flow into the main machine, and the cleaning device can maintain normal work in various postures. Therefore, the floor brush structure and the cleaning device can work in various occasions and postures, and are more convenient and flexible to use.

The specific structure, function and working principle of the floor brush structure 100 have been described in detail in the foregoing embodiments, and will not be described here.

[0087] Specifically, the main machine 201 can be connected with the floor brush structure 100 through a connecting rod 202 or the like, and the connecting rod 202 can be hinged to the shell 110 of the floor brush structure 100. In this way, the main machine 201 and the connecting rod 202 can have different height positions relative to the floor brush structure 100, and at this time, the connecting rod 202 correspondingly has different angles relative to the ground.

[0088] The main machine 201 can include a dust collecting assembly and a suction assembly, etc. The suction assembly is used to provide suction force, so that the dust, particles and other impurities on the ground enter the floor brush structure and are collected by the dust collecting assembly. It can be understood that the suction assembly can be communicated with the floor brush structure 100, for example, is communicated with the shell 110 of the floor brush structure 100.
