Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work under the premise that the scope of protection of the present application. The embodiments of the present application will be described in detail below with reference to the drawings.

[0052] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mount", "connect", "connection" should be understood in a broad sense, for example, it can be fixedly connected, or indirectly connected through an intermediate medium, or the internal communication of two elements or the interaction relationship between two elements. 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.

[0053] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0054] In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specified and limited.

[0055] The terms "first", "second", "third", "fourth" and the like in the specification and claims of the present application and the above drawings are used to distinguish similar objects, and do not necessarily indicate a particular order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0056] In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0057] In the related art, a cleaning device may include a main unit and a floor brush assembly connected to the main unit, wherein the main unit is connected to the floor brush assembly via a connecting rod. The floor brush assembly is used to clean a surface to be cleaned (e.g., the floor). Specifically, the floor brush assembly may include a cleaning member for wet mopping, which contacts the floor during operation.

[0058] The cleaning member of the floor brush assembly can be soaked first, and then the floor is wet-mopped using the cleaning member. Specifically, the cleaning member can include a roller brush rotating around a horizontal axis, or a mop that reciprocates relative to the floor.

[0059] However, before wet mopping the cleaning device, in order to prevent particles on the ground from being drawn into the cleaning parts and causing wear on the floor brush assembly or the floor, the user needs to first clean the particles and other dry garbage on the floor. This makes the floor cleaning operation time-consuming and labor-intensive, affecting the cleaning efficiency.

[0060] Based on this, an embodiment of the present application provides a floor brush structure and cleaning device. The floor brush structure is provided with a cyclone separation unit and a roller brush assembly. The roller brush assembly includes a dust collection roller brush and a mopping roller brush. The dust collection roller brush is used for dry mopping, and the mopping roller brush is used for wet mopping. The cyclone separation unit includes a separation box and a separation assembly. Under the action of the suction force provided by the main unit of the cleaning device, the fluid remaining on the ground after dry mopping by the dust collection roller brush enters the separation box through the air duct, and is separated in the separation box. The separation assembly separates the fluid into gas and a solid-liquid mixture. The solid-liquid mixture is thrown into the separation box, and the gas is discharged into the main unit of the cleaning device through the separation box. In this way, the user can complete the dry mopping and wet mopping operations on the floor at the same time without having to perform dry mopping or wet mopping separately. The cleaning operation is relatively simple and convenient, effectively reducing the user's labor intensity. Dry mopping and wet mopping work relatively independently, and the fluid remaining on the ground after dry mopping can be promptly sucked into the cyclone separation unit for separation, which also has a good cleaning effect.

[0061] Figure 1 A schematic diagram of the structure of a floor brush provided in an embodiment of the present application; Figure 2 for Figure 1 Schematic diagram of the internal structure; Figure 3 for Figure 2 Enlarged view of point A in the middle; Figure 4 A schematic diagram of the structure of the separation components in the floor brush structure provided in an embodiment of the present application; Figure 5 for Figure 4 Partial structure diagram Figure 1 ; Figure 6 for Figure 4 Schematic diagram of the internal structure of . It should be noted that, Figures 1 to 6 Shows a simplified schematic diagram of each component in the floor brush structure. The specific structure of the remaining components in the floor brush structure is not limited toFigures 1 to 6 of examples.

[0062] The floor brush structure provided in the embodiments of the present application is applied to a cleaning device. The cleaning device may include a main unit, wherein a suction assembly is provided within the main unit for providing suction to the floor brush structure. The cleaning device may be a household cleaning device such as a vacuum cleaner or a mop.

[0063] See also Figures 1 to 6 As shown, the floor brush structure may include a cyclone separation unit 100 , a shell 200 and a roller brush assembly 300 . The shell 200 has an air duct 210 , and the air duct 210 has a sewage suction port 211 .

[0064] The cyclone separation unit 100 includes a separation box 110 and a separation assembly 120 arranged in the separation box 110. The roller brush assembly 300 includes a mopping roller brush 310 and a dust collection roller brush 320 that are parallel to each other. The mopping roller brush 310 and the dust collection roller brush 320 are rotatably arranged on the shell 200. The dust collection roller brush 320 is located in front of the sewage suction port 211. The separation box 110 is connected to the air duct 210; the separation assembly 120 is used to separate the fluid entering the separation box 110 through the air duct 210.

[0065] In the present application, to clean the floor, the roller brush assembly 300 includes a dust collection roller brush 320 and a mopping roller brush 310. Both the dust collection roller brush 320 and the mopping roller brush 310 are rotatably mounted on the housing 200 and partially exposed at the bottom of the housing 200. The dust collection roller brush 320 is used for dry mopping. Its surface is relatively dry and it is primarily used to clean particles, dust, or other dry debris from the floor. The mopping roller brush 310 is used for wet mopping. Its surface is relatively wet and can be rolled relative to the floor to perform wet mopping, i.e., to clean the floor like a mop.

[0066] Specifically, the vacuum brush 320 and the mopping brush 310 can be arranged side by side, meaning that as the brush structure moves, one side performs dry mopping and the other side performs wet mopping. The vacuum brush 320 and the mopping brush 310 can also be arranged opposite each other along the direction of travel of the brush structure, meaning that dry mopping is performed first, followed by wet mopping. This minimizes interference between the vacuum brush 320 and the mopping brush 310 during operation, allowing dry and wet mopping operations to be completed relatively independently.

[0067] like Figure 1 As shown, in some embodiments, the separation box 110 can be disposed on the housing 200. In another embodiment, the separation box 110 can be disposed on the host. In other words, the present application does not impose any limitation on the location of the cyclone separation unit 100.

[0068] The residual fluid on the floor after the dry mop of the rolling brush 320 enters the separation tank 110 through the air duct 210, so as to be separated in the separation tank 110. In a specific implementation, the separation assembly 120 can be a cyclone cone, and the fluid entering the separation tank 110 through the air duct 210 is separated by rotating around the cyclone cone. As shown in Figure 5 The separation assembly 120 can also rotate relative to the separation tank 110 to separate the fluid entering the separation tank 110 through the air duct 210 into gas and solid-liquid mixture, and the separation tank 110 is used to store the solid-liquid mixture and discharge the gas. For ease of description, the drawings of the present application are described with the separation assembly 120 rotating relative to the separation tank 110.

[0069] The structure of the rolling brush 320 and the mop brush 310 can be the same or different. For example, the rolling brush 320 and the mop brush 310 can have the same size and the same surface material. In order to realize the wet mop operation on the floor, the circumferential surface of the mop brush 310 is a flexible surface. At this time, the surface of the mop brush 310 can be attached with a layer of soft material, such as wool.

[0070] In the present application, the suction port 211 of the air duct 210 on the shell 200 faces the surface (for example, the floor, which is described below) to be cleaned. The cyclone separation unit 100 is used to process the mixture of water stains, dust and particles. The mixture of gas, water stains, dust and particles can be collectively referred to as fluid. The rolling brush assembly 300 is used to clean the floor.

[0071] In a specific implementation, the separation tank 110 of the cyclone separation unit 100 is in communication with the air duct 210, and the separation tank 110 is used to communicate with the suction assembly in the main machine of the cleaning device, and the suction force provided by the suction assembly into the separation tank 110.

[0072] The above-mentioned suction force can drive the separation assembly 120 of the cyclone separation unit 100 to rotate relative to the separation tank 110, and the fluid enters the separation tank 110 through the air duct 210. The fluid in the separation tank 110 has a greater mass, and the centrifugal force is greater at the same speed. The water, water vapor, dust and particles (which can be collectively referred to as solid-liquid mixture) in the fluid have a greater speed, thereby generating a greater centrifugal force to be collected in the separation tank 110 away from the separation assembly 120. The gas in the fluid has a smaller centrifugal force, and is discharged to the main machine through the separation assembly 120 and the separation tank 110, so as to be discharged outside the cleaning device through the main machine, thereby avoiding water entering the main machine.

[0073] The mop structure provided by the embodiments of the present application is provided with a cyclone separation unit 100 and a rolling brush assembly 300, the rolling brush assembly 300 comprises a dusting rolling brush 320 and a mopping rolling brush 310, the dusting rolling brush 320 is used for dry mopping, and the mopping rolling brush 310 is used for wet mopping. The cyclone separation unit 100 comprises a separation box 110 and a separation assembly 120, and the separation assembly 120 is located in the separation box 110. Under the action of the suction force provided by the main machine of the cleaning device, the fluid remaining on the ground after dry mopping by the dusting rolling brush 320 enters the separation box 110 through the air duct 210, so that the fluid is separated in the separation box 110, the separation assembly 120 separates the fluid into gas and solid-liquid mixture, the solid-liquid mixture is thrown into the separation box 110, and the gas is discharged into the main machine of the cleaning device through the separation box 110. In this way, the user only needs to manipulate the mop structure to move during cleaning, so that the dry mopping and the wet mopping of the ground can be simultaneously completed during the movement of the mop structure relative to the ground, and the user does not need to additionally and separately perform the dry mopping or the wet mopping again, the cleaning operation is relatively simple and convenient, and the labor intensity of the user is effectively reduced. The dry mopping and the wet mopping are relatively independent, and the fluid remaining on the ground after dry mopping can be timely sucked into the cyclone separation unit 100 for separation, and the cleaning effect is also good.

[0074] In some embodiments, the mopping rolling brush 310 is located at the rear of the air duct 210. That is, the air duct 210 is located between the dusting rolling brush 320 and the mopping rolling brush 310, so that the cleaning operation of sequentially performing dry mopping, separating the fluid remaining on the ground after dry mopping and wet mopping is formed, and the cleaning efficiency is relatively high.

[0075] In the following, the structure of the separation assembly 120 is described.

[0076] Please continue to refer to Figures 4 to 6 As shown in the figure, in some embodiments, the separation assembly 120 can comprise a centrifugal fan 121 and a power fan 122, the centrifugal fan 121 and the power fan 122 are coaxially connected, the power fan 122 drives the centrifugal fan 121 to rotate, and the centrifugal fan 121 separates the fluid into gas and solid-liquid mixture.

[0077] The power fan 122 can also rotate under the driving of the gas separated by the centrifugal fan 121, so as to drive the centrifugal fan 121 to rotate. In specific implementation, the power fan 122 can be a spiral blade fan.

[0078] In some embodiments, the separation box 110 comprises a box body 111 and a box cover 112, and the box cover 112 is arranged on the box body 111. The centrifugal fan 121 is located in the box body 111, the box cover 112 has an installation cavity 1121 which is in communication with the box body 111, and the power fan 122 is located in the installation cavity 1121.

[0079] In the present application, the centrifugal fan 121 is arranged in the box body 111, and the power fan 122 is arranged in the mounting cavity 1121 of the box cover 112, that is, the centrifugal fan 121 and the power fan 122 are respectively located in different cavities, so that the centrifugal fan 121 can avoid that the fluid is directly discharged out of the dust cup box 110 through the power fan 122 after the fluid is fully separated in the box body 111 and enters the mounting cavity 1121 of the box cover 112.

[0080] In the present application, the box body 111 has an air inlet pipe 1111 which communicates with the box body 111, the air inlet pipe 1111 communicates with the air duct 210, and the box cover 112 has an air outlet pipe 1122 which communicates with the mounting cavity 1121; the air inlet pipe 1111 and the air outlet pipe 1122 are respectively located on opposite sides of the centrifugal fan 121.

[0081] The present application sets the air inlet pipe 1111, and the air inlet pipe 1111 communicates the air duct 210 with the box body 111, so that the box body 111 is connected with the air duct 210, thereby facilitating the smooth introduction of the fluid into the box body 111.

[0082] The air outlet pipe 1122 is arranged, and the air outlet pipe 1122 is used for communication of the suction assembly, so as to discharge the separated gas out of the separation box 110 through the air outlet pipe 1122.

[0083] The air inlet pipe 1111 and the air outlet pipe 1122 are respectively arranged on opposite sides of the centrifugal fan 121, so that the arrangement of the air inlet pipe 1111 and the air outlet pipe 1122 can avoid interference between the air inlet pipe 1111 and the air outlet pipe 1122.

[0084] In an embodiment, the air inlet pipe 1111 directly communicates with the air duct 210. In another embodiment, the air inlet pipe 1111 communicates with the air duct 210 through a pipeline. In specific implementation, the communication mode of the air inlet pipe 1111 and the air duct 210 is adaptively selected according to the position of the air duct 210 on the shell 200 and the position of the separation box 110, which is not limited in the present embodiment.

[0085] The ground brush structure provided in the present embodiment is that the box body 111 is barrel-shaped, and the air inlet pipe 1111 is tangent to the box body 111. Alternatively, the air inlet pipe 1111 is approximately tangent to the box body 111. In this way, the flow direction of the fluid can be controlled through the air inlet pipe 1111, for example, the flow direction of the fluid is shown by the solid arrow in Figure 5 , so as to guide the fluid to the inner side wall of the box body 111 through the air inlet pipe 1111.

[0086] Figure 7 For Figure 4 , the structure diagram of the centrifugal fan is shown. Referring to Figures 4 to 7As shown, in some embodiments, the rotation direction of the centrifugal fan 121 is consistent with the flow direction of the fluid entering the separation box 110. In this way, the centrifugal fan 121 is prevented from interfering with the flow direction of the fluid entering the box 111 when rotating, so that the fluid can smoothly enter the box 111 and be separated under the drive of the rotation of the centrifugal fan 121.

[0087] In a specific implementation, the centrifugal fan 121 is bowl-shaped, with the bowl mouth of the centrifugal fan 121 facing the box cover 112. The side of the centrifugal fan 121 is formed by multiple support rods 1211 evenly spaced apart. The support rods 1211 are inclined from the bottom of the bowl of the centrifugal fan 121 toward the bowl mouth of the centrifugal fan 121, and the inclination direction of the support rods 1211 is consistent with the rotation direction of the power fan 122.

[0088] In the present application, each support rod 1211 forms the side of the centrifugal fan 121. The support rods 1211 extend from the bottom of the bowl of the centrifugal fan 121 toward the bowl of the centrifugal fan 121, so that the side of the centrifugal fan 121 has a grid shape, and the interior of the centrifugal fan 121 is hollow. By aligning the tilt direction of the support rods 1211 with the rotation direction of the power fan 122, each support rod 1211 can stir the air flow during rotation, throwing the fluid to a position away from the rotation center of the centrifugal fan 121, thereby accelerating the fluid entering the housing 111.

[0089] Fluid along Figure 5 The solid arrow shown in FIG enters the box body 111, and the centrifugal fan 121 moves along Figure 5 As shown, centrifugal fan 121 rotates clockwise in the same direction as the fluid within casing 111. Centrifugal fan 121 exerts a higher velocity on the fluid, generating a greater centrifugal force. At the same speed, the greater the mass of the object, the greater the centrifugal force. Since the density of gas > the density of water vapor mixture > the density of solid matter, heavier objects move further away from the rotation axis I of centrifugal fan 121, while lighter gases move closer to centrifugal fan 121, thereby separating the gas from the water vapor and solid matter.

[0090] The gap between two adjacent support rods 1211 forms an inlet for the gas separated by the centrifugal fan 121 to enter the centrifugal fan 121 . The gas enters the interior of the centrifugal fan 121 and then enters the installation cavity 1121 .

[0091] Figure 8 for Figure 4 Schematic diagram of the structure of the middle guide; Figure 9 for Figure 4 Partial structure diagram Figure 2 ; Figure 10 for Figure 4 Exploded view of . Figures 4 to 10As shown, in order to avoid the fluid directly entering the installation cavity 1121 through the top of the separation assembly 120 without being separated by the separation assembly 120. In some embodiments, the separation assembly 120 further comprises a guide 123 located in the box body 111; the guide 123 is arranged between the centrifugal fan 121 and the box cover 112 to guide the fluid at the top of the centrifugal fan 121 to the side of the centrifugal fan 121.

[0092] In some embodiments, the guide 123 can be a guide ring, and the end of the guide ring can be fixed to the surface of the box cover 112 facing the box body 111. The upper part of the centrifugal fan 121 is located in the guide ring.

[0093] In another embodiment, the guide 123 can be a reverse prevention fan, which is coaxially connected with the centrifugal fan 121 and rotates in the same direction with the centrifugal fan 121.

[0094] The reverse prevention fan is located between the centrifugal fan 121 and the power fan 122. In other words, the reverse prevention fan is arranged above the centrifugal fan 121, and rotates in the same direction with the centrifugal fan 121 to guide the fluid above the separation assembly 120 to the side of the separation assembly 120, thereby avoiding the fluid directly entering the installation cavity 1121 through the top of the separation assembly 120.

[0095] In specific implementation, the side wall of the reverse prevention fan is uniformly and spacedly provided with a plurality of guide ribs 1231, the guide ribs 1231 are arranged obliquely, and the oblique direction of the guide ribs 1231 is consistent with the oblique direction of the supporting rod 1211. In this way, in the process of rotation of the reverse prevention fan, the fluid above the separation assembly 120 is guided to the side of the separation assembly 120 through the guide ribs 1231.

[0096] Please continue to refer to Figure 4 、 Figure 5 、 Figure 8 and Figure 9 As shown, the brush structure provided by the embodiments of the present application, the box cover 112 comprises a box cover body 1123, and the surface of the box cover body 1123 facing the centrifugal fan 121 is provided with a groove 1124, and the groove 1124 is protruded towards the side away from the centrifugal fan 121.

[0097] The guide 123 is located in the groove 1124, the bowl opening of the centrifugal fan 121 surrounds the circumferential side of the groove of the groove 1124, and the end of the guide 123 is inserted into the centrifugal fan 121.

[0098] Specifically, the recess 1124 provides installation space for the anti-reverse fan. The inner side wall of the recess 1124 can match the outer side wall of the guide piece 123 (for example, the outer side wall of the anti-reverse fan), and a gap is provided between the inner side wall of the recess 1124 and the outer side wall of the anti-reverse fan to avoid affecting the rotation of the anti-reverse fan. A gap is provided between the bowl opening of the centrifugal fan 121 and the surface of the box cover body 1123 facing the centrifugal fan 121 to allow the centrifugal fan 121 to rotate smoothly.

[0099] The end of the guide piece 123 is inserted into the centrifugal fan 121, and the side surface of the guide piece 123 blocks the gap between the bowl opening of the centrifugal fan 121 and the surface of the box cover body 1123 facing the centrifugal fan 121 to avoid the fluid entering the centrifugal fan 121 directly through the bowl opening of the centrifugal fan 121.

[0100] In order to allow the gas to enter the installation cavity 1121 smoothly, in some embodiments, the recess 1124 has a wind guide assembly 1125, the recess 1124 has a communication hole 1124a on the groove bottom, the communication hole 1124a is adjacent to the gas outlet pipe 1122, the wind guide assembly 1125 is in communication with the installation cavity 1121 through the communication hole 1124a, and the gas enters the gas outlet pipe 1122 through the centrifugal fan 121, the guide piece 123 and the installation cavity 1121 in sequence.

[0101] In specific implementation, the wind guide assembly 1125 includes a blocking ring 1125a, a support column 1125b and a guide piece 1125c, the side wall of the anti-reverse fan is located between the recess and the blocking ring 1125a, the support column 1125b is arranged in the blocking ring 1125a, and the support column 1125b is coaxially arranged with the centrifugal fan 121.

[0102] The guide piece 1125c is inclinedly connected between the blocking ring 1125a and the support column 1125b, the inclination direction of the guide piece 1125c is consistent with the inclination direction of the support rod 1211, and the end of the guide piece 1125c is connected with the inner wall of the communication hole 1124a.

[0103] Specifically, the guide piece 1125c can be in a spiral shape, the guide piece 1125c surrounds the circumferential side of the support column 1125b, and the guide piece 1125c, the inner side wall of the blocking ring 1125a and the outer side wall of the support column 1125b together form a guide groove, so that the gas spirally rises through the guide groove and enters the installation cavity 1121 through the communication hole 1124a.

[0104] The number of turns of the guide piece 1125c around the circumferential side of the support column 1125b can be less than one turn, and the gas can be guided to the communication hole 1124a.

[0105] In the present application, the surface of the box cover body 1123 away from the centrifugal fan 121 has a support part 1126, and the support part 1126 and the box cover body 1123 jointly form a mounting cavity 1121 and an air outlet pipe 1122.

[0106] The air outlet pipe 1122 has an air outlet 1122a, which is located below the mounting cavity 1121. In other words, the air outlet 1122a is arranged below the power fan 122.

[0107] In the present application, the air outlet 1122a is arranged below the power fan 122, and the suction assembly on the main machine is located above the air outlet 1122a. When the suction assembly works, a negative pressure is formed at the air outlet 1122a. Since the power fan 122 is located in the box cover 112, and the centrifugal fan 121 and the anti-backflow fan are both located in the box body 111, that is, the centrifugal fan 121 and the anti-backflow fan are separated from the power fan 122 by two cavities. The power fan 122 is communicated with the other two (i.e., the centrifugal fan 121 and the anti-backflow fan) through the communication hole 1124a, and the gas can only pass through the communication hole 1124a. Therefore, a negative pressure is formed at the position of the communication hole 1124a, and the fluid from the air outlet pipe 1122 enters the box body 111, and the gas separated by the centrifugal fan 121 flows to the air guiding assembly 1125 through the anti-backflow fan, and under the guiding action of the guiding piece 1125c, the gas impacts the blades of the power fan 122 in the flow process, so that the power fan 122 rotates in the set direction.

[0108] In some embodiments, the separation assembly 120 further comprises a mounting shaft 124, which is inserted on the support column 1125b, and the centrifugal fan 121, the power fan 122 and the anti-backflow fan are sleeved on the mounting shaft 124 and are fixedly connected with the mounting shaft 124. In this way, the centrifugal fan 121, the power fan 122 and the anti-backflow fan rotate synchronously and in the same direction, that is, they rotate together in the set direction.

[0109] In specific implementation, the middle part of the centrifugal fan 121, the power fan 122 and the anti-backflow fan all have mounting columns. The mounting shaft 124 is inserted on the mounting columns. The mounting column of the centrifugal fan 121 can be the bottom of the bowl of the centrifugal fan 121. The mounting column of the anti-backflow fan is connected with the side wall of the anti-backflow fan by at least two connecting rods. The connecting rods form air holes for the gas to pass through.

[0110] In addition, in the present application, the support part 1126 has a mounting hole 1126a, and the box cover 112 further comprises a cover body 1127, which covers the mounting hole 1126a and is located above the power fan 122. In other words, the mounting cavity 1121 can be exposed by opening the cover body 1127, so that the power fan 122 can be installed or repaired in the mounting cavity 1121.

[0111] In order to obtain a larger rotating speed of the centrifugal fan 121, the power fan 122 and the anti-backup fan under a smaller suction force. In some embodiments, at least one of the cover 1127 and the support column 1125b has a bearing 1128 sleeved on the mounting shaft 124.

[0112] Figure 11 For Figure 1 the partial exploded view. As shown in Figure 1 , Figure 2 and Figure 11 , the housing 200 has a mounting groove 220, and the box body 111 is detachably connected with the mounting groove 220, and the box cover 112 is detachably connected with the box body 111. In this way, the separation tank 110 can be taken off from the housing 200, and the box cover 112 is opened, so as to pour the collected solid-liquid mixture in the box body 111, so as to facilitate the recycling of the separation tank 110.

[0113] In the mounting groove 220 and the mounting groove 220 can be detachably connected by clamping, inserting and the like. The box cover 112 and the box body 111 can be detachably connected by clamping, inserting, screwing and the like.

[0114] In specific implementation, the mounting groove 220 can be matched with the box body 111, that is, the inner side wall of the mounting groove 220 abuts against the outer side wall of the box body 111, so as to avoid dust and other sundries from entering the box body 111 through the mounting groove 220.

[0115] When the mop roller 310 performs wet mopping on the ground, the dirty water on the mop roller 310 can be guided into the air duct 210 through the water guiding structure.

[0116] Hereinafter, the water guiding structure for guiding the dirty water on the mop roller 310 into the air duct 210 will be described in combination with the structure of the roller assembly 300.

The diameters of the mopping roller brush 310 and the dusting roller brush 320 can be equal, the axes of the mopping roller brush 310 and the dusting roller brush 320 are parallel, and the axes of the mopping roller brush 310 and the dusting roller brush 320 can be located in the same horizontal plane. In this way, the mopping roller brush 310 and the dusting roller brush 320 rotate more balanced when working, which is beneficial to keep the ground brush structure stable during working and maintain a horizontal posture.

[0119] In some embodiments, the bottom of the shell 200 is further provided with a blocking strip 230, which is located between the air duct 210 and the mopping roller brush 310. The blocking strip 230, the mopping roller brush 310 and the dusting roller brush 320 all contact the ground. The blocking strip 230 and the dusting roller brush 320 form a dusting area, and the area where the mopping roller brush 310 contacts the ground can be referred to as a mopping area. The blocking strip 230 separates the mopping roller brush 310 and the dusting roller brush 320, thereby separating the dusting area and the mopping area.

[0120] In some embodiments, the blocking strip 230 can be a flexible member, such as a rubber member or a silicone member.

[0124] In the present application, the water on the mopping roller brush 310 is scraped off by the scraping strip 430, and the water enters the water receiving member 420 along the scraping strip 430. The water on the mopping roller brush 310 is guided into the air duct 210 through the connecting pipe 410, and then is sucked into the separation tank 110 for separation.

The air duct 210 and the water outlet end of the water receiving member 420 can both be provided with an interface, and the two ends of the hose are respectively sleeved on the interface of the air duct 210 and the interface of the water outlet end of the water receiving member 420. The water receiving member 420 can be arranged in the shell 200. In some embodiments, the water receiving member 420 can be integrally formed with the shell 200.

[0126] The extension direction of the scraping strip 430 is consistent with the axial direction of the mopping roller brush 310. The end of the scraping strip 430 is flush with the end of the mopping roller brush 310, or the end of the scraping strip 430 is located outside the end of the mopping roller brush 310. That is, the length of the scraping strip 430 can be equal to the axial length of the mopping roller brush 310, or greater than the axial length of the mopping roller brush 310. Correspondingly, the two ends of the port of the water inlet end of the water receiving member 420 can be flush with the two ends of the scraping strip 430, so that the water inlet end of the water receiving member 420 can fully receive the sewage scraped off the mopping roller brush 310 by the scraping strip 430.

[0127] In some embodiments, the water guide assembly 400 further comprises a push piece 440 arranged below the water inlet end of the water receiving member 420, and the push piece 440 is in contact with the mopping roller brush 310. The push piece 440 can push the solid waste on the mopping roller brush 310 down, preventing the solid waste from blocking the water inlet end of the water receiving member 420.

[0128] The push piece 440 can be a soft push piece. The push piece 440 can be in interference fit with the mopping roller brush 310, preventing sewage from leaking out between the mopping roller brush 310 and the water receiving member 420.

[0129] In addition, the shell 200 further has a connecting channel 240, the air outlet 1122a is opposite to the connecting channel 240, and the air outlet pipe 1122 is in communication with the connecting channel 240.

[0132] The liquid storage tank 510 can store liquid, and the liquid can be clean water or a mixed cleaning liquid of clean water and a cleaning agent. The liquid storage tank 510 can be detachably arranged on the shell 200. The liquid storage tank 510 and the separation tank 110 can be arranged opposite to each other along the axial direction of the mopping roller brush 310. Thus, the counterweight of the floor brush structure is facilitated.

[0133] The driving member 520 may be a water pump. The water spraying member 530 may be a plurality of nozzles. The water pump delivers liquid from the liquid storage tank 510 to the water spraying member 530. The water spraying member 530 delivers the liquid to the mopping roller brush 310 to moisten the mopping roller brush 310.
