In the related art, the cleaning apparatus may include a main body and a brush assembly connected to the main body, the main body being connected to the brush assembly through a connection rod. The floor brush assembly is used for cleaning a surface to be cleaned (e.g., floor). In particular, the floor brush assembly may include cleaning elements for wet mopping that are in contact with the floor during operation.

The cleaning elements of the brush assembly may be wetted prior to wet mopping the floor with the cleaning elements. In particular, the cleaning elements may comprise a roller brush which rotates about a horizontal axis of rotation, a mop which reciprocates relative to the floor, or the like.

However, before the cleaning device is wet towed, in order to avoid the particles on the ground from being involved in the cleaning member, abrasion is caused to the ground brush assembly or the ground, and the user needs to clean dry garbage such as the particles on the ground, so that the cleaning operation on the ground is time-consuming and labor-consuming, and the cleaning efficiency is affected.

Fig. 1 to 6 are schematic diagrams illustrating components in the floor brush structure, and specific structures of the remaining components in the floor brush structure are not limited to the illustrations of fig. 1 to 6.

The ground brush structure is applied to cleaning equipment. Wherein the cleaning apparatus may comprise a main machine in which a suction assembly is provided for providing suction to the floor brush structure. The cleaning device can be a household cleaning device such as a dust collector, a floor cleaning machine and the like.

Referring to fig. 1 to 6, the floor brush structure may include a cyclone unit 100, a housing 200, and a roll brush assembly 300, the housing 200 having an air duct 210 thereon, the air duct 210 having a dirt suction port 211.

The cyclone separation unit 100 comprises a separation box 110 and a separation assembly 120 arranged in the separation box 110, the rolling brush assembly 300 comprises a mopping rolling brush 310 and a dust collection rolling brush 320 which are parallel to each other, the mopping rolling brush 310 and the dust collection rolling brush 320 are rotatably arranged on the shell 200, the dust collection rolling brush 320 is positioned in front of the dirt suction opening 211, and the separation box 110 is communicated with the air duct 210; the separation assembly 120 is used to separate fluid entering the separation tank 110 via the air duct 210.

In this application, in order to perform a cleaning operation on the floor, the roller brush assembly 300 includes a dust suction roller brush 320 and a floor mopping roller brush 310, and the dust suction roller brush 320 and the floor mopping roller brush 310 are rotatably disposed on the housing 200 and partially exposed from the bottom of the housing 200. The dust-absorbing rolling brush 320 is used for dry dragging, and the surface of the dust-absorbing rolling brush 320 is drier and is mainly used for cleaning particles, dust or other dry garbage on the ground. The mopping roller brush 310 is used for wet mopping, the mopping roller brush 310 has a cleaner surface that is wet, and the mopping operation on the floor, i.e., mopping the floor like a mop, can be performed by rolling the mopping roller brush 310 relative to the floor.

Specifically, the dust-absorbing roller brush 320 and the floor-mopping roller brush 310 may be disposed side by side, that is, dry mopping is performed on one side and wet mopping is performed on the other side while the floor-brush structure is traveling. The dust-absorbing rolling brush 320 and the floor-mopping rolling brush 310 may be disposed opposite to each other along the traveling direction of the floor brush structure, that is, dry mopping is performed first, and wet mopping is performed. The dust suction roller brush 320 and the floor roller brush 310 have less interference with each other in operation, and dry and wet mopping operations can be completed relatively independently.

As shown in fig. 1, in some embodiments, the separator tank 110 may be provided on the housing 200. In another embodiment, the separator tank 110 may be provided on the host. That is, the present application does not impose a limitation on the location of the cyclone unit 100.

The fluid remained on the floor surface after the dust suction roller brush 320 is dry-dragged enters the separation box 110 through the air duct 210, thereby being separated in the separation box 110. In particular implementations, the separation assembly 120 may be a cyclone cone about which fluid entering the separation tank 110 through the air duct 210 is rotationally separated. As shown in fig. 5, the separation assembly 120 may also be rotated relative to the separation tank 110 to separate the fluid entering the separation tank 110 through the air duct 210 into a gas and a solid-liquid mixture, and the separation tank 110 is configured to receive the solid-liquid mixture and to discharge the gas. For ease of description, the figures herein illustrate the rotation of the separation assembly 120 relative to the separation housing 110.

The dust-absorbing roller brush 320 and the floor-mopping roller brush 310 may have the same or different structures. For example, the dust collection roller brush 320 and the floor roller brush 310 may each have the same size and the same surface material. To achieve wet mopping of the ground, the circumferential surface of the mopping roller brush 310 is a flexible surface. At this time, a layer of soft material, such as wool tops, may be attached to the surface of the floor scrubbing roller brush 310.

In the present application, the dirt suction port 211 of the air duct 210 on the housing 200 faces a surface to be cleaned (e.g., the floor, which will be described below). The cyclone unit 100 is used for treating a mixture of water stains, dust, particles and the like. Wherein the mixture of gas, water stains, dust and particles and other impurities may be collectively referred to as a fluid. The roller brush assembly 300 is used to clean the floor.

In particular, the separating bin 110 of the cyclonic separating unit 100 is adapted to communicate with a suction assembly within a main machine of the cleaning apparatus by communicating with the air duct 210, the suction force provided by the suction assembly into the separating bin 110.

The suction force may drive the separating assembly 120 of the cyclonic separating unit 100 to rotate relative to the separating bin 110 and draw fluid into the separating bin 110 via the duct 210. The greater the mass of the object, the greater the centrifugal force of the fluid entering the separator tank 110 at the same velocity. Heavier mass of water, moisture, dust, and particulate impurities (which may be collectively referred to as solid-liquid mixtures) in the fluid attains a greater velocity and thus generates a greater centrifugal force to be collected in the separation tank 110 away from the separation assembly 120. The lighter-weight gas in the fluid is discharged to the main machine through the separation assembly 120 and the separation tank 110 with less centrifugal force, so that the cleaning device is discharged through the main machine, thereby preventing the main machine from water inflow.

According to the floor brush structure provided by the embodiment of the application, by arranging the cyclone separation unit 100 and the rolling brush assembly 300, the rolling brush assembly 300 comprises the dust collection rolling brush 320 and the floor mopping rolling brush 310, the dust collection rolling brush 320 is used for dry mopping, and the floor mopping rolling brush 310 is used for wet mopping. The cyclonic separating unit 100 comprises a separating box 110 and a separating assembly 120, the separating assembly 120 being located within the separating box 110. Under the action of the suction force provided by the main machine of the cleaning device, the fluid remained on the floor surface after the dust collection rolling brush 320 is dried and dragged enters the separation box 110 through the air duct 210, so that separation is performed 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. Therefore, a user only needs to operate the floor brush structure to travel during cleaning, and can finish dry-mopping and wet-mopping operations on the ground in the traveling process of the floor brush structure relative to the ground, and the user does not need to separately dry-mopping or wet-mopping again, so that the cleaning operation is simple and convenient, and the labor intensity of the user is effectively reduced. The dry and wet mops work relatively independently, and the residual fluid on the ground after the dry mopping can be timely sucked into the cyclone separation unit 100 for separation, so that the cleaning effect is good.

In some embodiments, the floor roller brush 310 is positioned behind the air chute 210. That is, the air duct 210 is located between the dust suction roller brush 320 and the mopping roller brush 310, thereby forming a cleaning operation of sequentially performing dry mopping, cleaning fluid remaining on the floor after dry mopping, and wet mopping, and cleaning efficiency is high.

Hereinafter, the structure of the separation unit 120 will be described.

With continued reference to fig. 4-6, in some embodiments, the separation assembly 120 may include a centrifugal fan 121 and a power fan 122, where the centrifugal fan 121 and the power fan 122 are coaxially connected, and the power fan 122 rotates the centrifugal fan 121, and the centrifugal fan 121 separates the fluid into a gas and a solid-liquid mixture.

The power fan 122 may also be driven to rotate by the gas separated by the centrifugal fan 121, so as to drive the centrifugal fan 121 to rotate. In particular implementations, the power fan 122 may be a helical blade fan.

In some embodiments, the separator tank 110 includes a tank 111 and a tank cover 112, with the tank cover 112 being disposed over the tank 111. The centrifugal fan 121 is located in the case 111, the case cover 112 has a mounting cavity 1121 communicating with the case 111, and the power fan 122 is located in the inner mounting cavity 1121.

In this application, the centrifugal fan 121 is disposed in the case 111, and the power fan 122 is disposed in the mounting cavity 1121 of the case cover 112, that is, the centrifugal fan 121 and the power fan 122 are respectively disposed in different cavities, so that after the centrifugal fan 121 fully separates the fluid in the case 111, the fluid can be prevented from being directly discharged out of the dust cup case 110 through the power fan 122 without being separated by the centrifugal fan 121 in the mounting cavity 1121 of the case cover 112.

In the present application, the box 111 is provided with an air inlet pipe 1111 communicated with the box 111, the air inlet pipe 1111 is communicated with the air duct 210, and the box cover 112 is provided with an air outlet pipe 1122 communicated with the installation cavity 1121; the air inlet pipe 1111 and the air outlet pipe 1122 are respectively located at opposite sides of the centrifugal fan 121.

The air inlet pipe 1111 is arranged, the air duct 210 is communicated with the box body 111 through the air inlet pipe 1111, so that the box body 111 is in butt joint with the air duct 210, and fluid can be smoothly guided into the box body 111.

An outlet duct 1122 is provided, the outlet duct 1122 being adapted for communication with the suction assembly so as to facilitate the discharge of the separated gas out of the separation tank 110 through the outlet duct 1122.

The air inlet pipe 1111 and the air outlet pipe 1122 are respectively arranged at two opposite sides of the centrifugal fan 121, so that the air inlet pipe 1111 and the air outlet pipe 1122 are conveniently arranged, and the mutual interference of the air inlet pipe 1111 and the air outlet pipe 1122 can be avoided.

In one embodiment, the air inlet pipe 1111 communicates directly with the air duct 210. In another embodiment, the air inlet pipe 1111 communicates with the air duct 210 through a pipe. In a specific implementation, the communication mode between the air inlet pipe 1111 and the air duct 210 is adaptively selected according to the position of the air duct 210 on the housing 200 and the position of the separation box 110, which is not limited herein.

In the floor brush structure provided by the embodiment of the application, the box body 111 is barrel-shaped, and the air inlet pipe 1111 is tangent to the box body 111. Alternatively, the intake pipe 1111 is approximately tangential to the housing 111. In this way, the flow direction of the fluid may be controlled by the intake pipe 1111, for example, as indicated by solid arrows in fig. 5, so that the fluid is guided to the inner side wall of the case 111 via the intake pipe 1111.

Fig. 7 is a schematic view of the centrifugal fan in fig. 4. Referring to fig. 4-7, in some embodiments, the centrifugal fan 121 rotates in a direction that is consistent with the flow direction of fluid into the separator tank 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 driving of the rotation of the centrifugal fan 121.

In a specific implementation, the centrifugal fan 121 is bowl-shaped, the bowl opening of the centrifugal fan 121 faces the case cover 112, the side surface of the centrifugal fan 121 is formed by uniformly and alternately arranging a plurality of support rods 1211, the support rods 1211 incline from the bowl bottom of the centrifugal fan 121 toward the bowl opening 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.

In this application, each support rod 1211 forms a side surface of the centrifugal fan 121, and the support rods 1211 extend from the bowl bottom of the centrifugal fan 121 toward the bowl opening of the centrifugal fan 121 so that the side surface of the centrifugal fan 121 is in a grid shape and the inside of the centrifugal fan 121 is hollow. By setting the inclination direction of the support rods 1211 to coincide with the rotation direction of the power fan 122, each support rod 1211 can agitate the air flow during rotation, and throw the fluid to a position away from the rotation center of the centrifugal fan 121, thereby accelerating the fluid entering the casing 111.

The fluid enters the housing 111 along the solid arrows shown in fig. 5, the centrifugal fan 121 rotates in the clockwise direction shown in fig. 5, and the centrifugal fan 121 rotates in the same direction as the fluid in the housing 111. Under the action of the centrifugal fan 121, the fluid is brought to a greater speed, thereby generating a greater centrifugal force. At the same speed, the greater the mass of the object, the greater the centrifugal force, and since the gas density > the vapor mixture density > the solid matter density, the heavier the object is away from the rotational axis I of the centrifugal fan 121, the closer the gas centrifugal fan 121 is to the density, thereby separating the gas from the vapor and solid matter.

The gap between the adjacent two support rods 1211 forms an inlet through which the gas separated by the centrifugal fan 121 enters the centrifugal fan 121, and the gas enters the inside of the centrifugal fan 121 and thus the installation cavity 1121.

FIG. 8 is a schematic view of the guide of FIG. 4; FIG. 9 is a second schematic diagram of a portion of the structure of FIG. 4; fig. 10 is an exploded view of fig. 4.

the anti-reverse fan is located between the centrifugal fan 121 and the power fan 122. In other words, an anti-reverse fan is disposed above the centrifugal fan 121, and the anti-reverse fan rotates in the same direction as the centrifugal fan 121 to guide the fluid above the separation assembly 120 to the side of the separation assembly 120, thereby preventing the fluid from directly entering the installation cavity 1121 through the upper side of the separation assembly 120.

In particular, the sidewalls of the anti-reverse fan are uniformly provided with a plurality of guide ribs 1231 at intervals, the guide ribs 1231 are inclined, and the inclination direction of the guide ribs 1231 coincides with the inclination direction of the support rod 1211.

A gap is provided between the bowl opening of the centrifugal fan 121 and the surface of the cover body 1123 facing the centrifugal fan 121 so that the centrifugal fan 121 can smoothly rotate.

The end of the guide member 123 is inserted into the centrifugal fan 121, so that the side surface of the guide member 123 seals the gap between the bowl opening of the centrifugal fan 121 and the surface of the cover body 1123 facing the centrifugal fan 121, and fluid is prevented from directly entering the centrifugal fan 121 through the bowl opening of the centrifugal fan 121.

The power fan 122 communicates with the other two (i.e., the centrifugal fan 121 and the anti-reverse fan) through the communication hole 1124a, and the gas can pass through only the communication hole 1124 a. Therefore, a negative pressure is generated at the position of the communication hole 1124a, fluid enters the case 111 from the air outlet pipe 1122, and the gas separated by the centrifugal fan 121 flows through the air guide member 1125 by the air anti-reverse fan, and the gas is guided by the guide piece 1125c to impact the blades of the power fan 122 during the flowing process, so that the power fan 122 is rotated in a set direction.
