In the present invention, unless otherwise indicated, terms of orientation such as "upper, lower, top, bottom" are used generally with respect to the orientation shown in the drawings or with respect to the component itself in the vertical, upright or gravitational direction; also, for ease of understanding and description, "inner and outer" refers to inner and outer relative to the profile of each component itself, but the above-mentioned orientation terms are not intended to limit the present invention.

Referring to fig. 1 to 14, the present invention provides a floor brush assembly 100, wherein the floor brush assembly 100 is used for cleaning a surface to be cleaned. The forward direction of the floor brush assembly 100 is forward and the backward direction opposite to the forward direction is backward. The floor brush assembly 100 includes: a floor brush base, a roller brush 110, and a second scraper 300. The second scraping member 300 is disposed at the bottom of the ground brush base body and in front of the rolling brush 110. The rolling brush 110 is rotatably arranged on the ground brush base body.

In one illustrative scenario, the brush assembly 100 may be used in a floor scrubber for cleaning the floor surface of a floor. It should be noted that the above example of the brush assembly 100 being used as a floor scrubber is only one possible scenario for the brush assembly 100. In other possible and not explicitly excluded scenarios, the floor brush assembly 100 may also be applied to a hand-held cleaner.

The floor brush assembly 100 will be described hereinafter as applied to a floor scrubber where the surface to be cleaned is a floor surface. It will be appreciated from the foregoing that the scope of embodiments of the invention is not limited thereby.

In this embodiment, the ground brush base body includes a main base body 120 and a rolling brush cover 130 detachably disposed on the main base body 120, and the main base body 120 and the rolling brush cover 130 together enclose a rolling brush cavity 160 for accommodating the rolling brush 110. The main housing 120 is provided with a cleaning liquid delivery unit (not shown) for wetting the rolling brush 110 and a scraping unit (not shown) for pressing the outer circumferential surface of the rolling brush 110 so that the sewage adsorbed on the rolling brush 110 drops down to be sucked by the suction port. Specifically, when the floor brush assembly 100 is operated, the roller brush 110 is rotated at a high speed by the motor built in the floor brush assembly 100, and the roller brush 110 can bring dirt on the floor below the floor brush into the suction port, and simultaneously the floor is wiped by the roller brush 110 moistened by the cleaning liquid delivery unit, thereby completing the floor cleaning.

Referring to fig. 3 and 4, the second scraping member 300 extends in the axial direction of the roll brush 110. The second scraping member 300 is provided with at least two second protrusions 310 spaced apart along the length direction thereof, wherein the number of the second protrusions 310 may be two, three, or a plurality of, and may be specifically determined according to the size of the floor brush base body.

In this embodiment, when the floor brush assembly moves forward, at least the roller brush 110 abuts against the ground, and the gap between the adjacent second protrusions 310 forms a second channel H2 allowing dirt to pass through, so that the dirt reaches the suction port of the floor brush base body, thereby eliminating the need to tilt the front side of the floor brush assembly or lift the floor brush assembly. Thus, the floor brush assembly 100 does not form a soil strip distributed along the second scraper 300 in front of the second scraper 300 during the forward movement.

The above-mentioned "when the floor brush assembly moves forward, at least the rolling brush 110 is in contact with the surface to be cleaned" may be understood as that the rolling brush 110 is in contact with the floor, the second bump 310 is not in contact with the floor, and it may be understood that the rolling brush 110 and the second bump 310 are in contact with the floor, respectively.

Preferably, when the ground brush assembly moves forward, the bottom surface of the second bump 310 is abutted against the ground, i.e., the roller brush 110 and the second bump 310 are respectively abutted against the ground. Thus, while the second passage H2 of the second scraper 300 allows the dirt to pass therethrough, the bottom surface of the second projection 310 can scrape the dirt on the floor, which has an advantage of good cleaning effect.

Referring to fig. 3 and 6, the second scraping member 300 includes a second scraping body 301 disposed at the bottom of the base of the floor brush, and the second protrusions 310 spaced apart from the second scraping body 301. Wherein the second protrusions 310 are spaced apart along the length direction of the second scraping body 301. The "intervals" may be equally spaced, randomly spaced, or regularly spaced.

Further, the top (ground-away side) of the second scraping body 301 is provided with a second mounting portion 320 for connection with the floor brush base body. The second scraping body 301 further has a second abutting portion for abutting against the ground, the second abutting portion being distributed opposite to the second mounting portion 320.

In this embodiment, when the ground brush assembly moves forward, the second scraping body 301 swings backward under the action of an external force, so that the second bump 310 abuts against the ground, and at this time, the second scraping member 300 is in the fourth state. When the ground brush assembly moves backward, the second scraping body 301 swings forward under the action of an external force, so that the second abutting portion abuts against the ground, and at this time, the second scraping member 300 is in the third state. As can be seen from the above, the second scraper 300 can be changed between the third state and the fourth state by an external force.

In this embodiment, the material of the second scraper 300 affects the type of external force. Specifically, when the second scraping member 300 is made of a deformable material, the above-mentioned external force is a frictional force between the second scraping body 301 and the ground. When the floor brush assembly moves forward, the second scraping body 301 swings backward with the second mounting portion 320 as a fulcrum after receiving the frictional force; when the brush assembly moves rearward, the second scraping body 301 swings forward about the second mounting portion 320 as a fulcrum after receiving a frictional force.

When the second scraping member 300 is made of a hard material, the external force is a force provided by a driving mechanism (not shown) provided on the base body of the floor brush, and the force provided by the driving mechanism is configured to drive the second scraping member 300 to switch between the third state and the fourth state.

It is noted that the hard material is a material which is not deformable when subjected to an external force. The deformable material is a material capable of deforming when subjected to an external force.

In this embodiment, the second scraping member 300 is preferably made of a deformable material, wherein the second scraping member 300 is made of a deformable material means: the second scraper body 301 and the second bump 310 are both made of a deformable material. The deformable material may be rubber, silicone, or the like, and thus can be deformed by friction.

Specifically, the second scraping body 301 is made of a deformable material so as to be deformable; the deformable material is used for the second bump 310 to avoid scratching the ground, which may cause damage to the ground. In addition, the second scraping body 301 and the second bump 310 are made of the same material, which is convenient for production and manufacturing. It will be appreciated that the second scraping body 301 and the second bump 310 may also be made of different deformable materials, such as rubber materials for the scraping body 200 and silicone materials for the second bump 310. The scope of the embodiments of the invention is not limited in this respect.

Further, the second scraping body 301 is in a sheet shape, the second scraping body 301 has a third face 3011 on the side close to the roll brush 110 and a fourth face 3012 on the side far from the roll brush 110, and the fourth face 3012 is provided with the second bump 310. That is, the third and fourth tetrahedrons 3011 and 3012 are disposed back to back, and the second protrusions 310 are provided on the surface facing away from the roll brush 110.

In the present embodiment, the second contact portion has a contact surface capable of being brought into contact with the ground, and the contact surface of the second contact portion is at least one of the third face 3011, and a bottom adjacent face between the third face 3011 and the fourth face 3012.

The contact surface of the second contact portion is preferably the third face 3011, for the following reasons: when the abutment surface of the second abutment portion is the third face 3011, the second scraping body 301 is better in the grounding capability. When the floor brush assembly 100 moves backward, the residual water and the residual dirt on the floor can be effectively pushed toward the roll brush 110 side, thereby effectively reducing the residual water and the residual dirt on the floor when the floor brush assembly 100 moves backward.

Referring to fig. 1 in combination with fig. 5, in order to further enhance the cleaning ability of the second scraping member 300 when the floor brush assembly 100 moves backward, the floor brush base body is provided with a retaining plate 133, and in this embodiment, the retaining plate 133 is disposed at the bottom of the roller brush cover 130. The extension flap 133 serves to apply downward pressure to the second scraper 300 in the third state so that the second scraper 300 abuts against the ground.

Specifically, the extension baffle 133 is located at the front side of the second scraper 300, and the bottom edge of the extension baffle 133 is lower than the second mounting portion 320. When the floor brush assembly 100 moves backward (in the third state), the second protrusion 310 of the second scraping member 300 abuts against the bottom edge of the extension plate 133, the second scraping body 301 cannot swing forward further under the action of the extension plate 133, at this time, the extension plate 133 applies downward pressure to the second scraping body 301, the extension plate 133 can enable the second scraping body 301 to abut against the ground, the scraping force of the second scraping body 301 against the ground can be effectively increased, the cleaning of residual water and dirt on the ground is facilitated, and the sealing performance of the rolling brush 110 is improved to a certain extent.

In the present embodiment, the second bump 310 is in a block shape, and the second bump 310 has a second friction surface 311 away from the second scraping body 301 side. When the second scraper 300 is in the fourth state, the second friction surface 311 is a bottom surface of the second bump 310, and the second friction surface 311 abuts against the ground. The second friction surface 311 may be a plane, or an arc surface, or a curved surface, or at least one of a plane, a fold line surface, and an arc surface.

In the present embodiment, the distance between the second friction surface 311 and the second scraping body 301 is defined as a distance L2, the distance L2 defining the height of the second channel H2. The height L2 of the second channel H2 determines the size of the dirt that can pass through, in particular the height dimension of the dirt.

Specifically, the distance L2 is 3mm or more and 10mm or less. The distance L2 may be 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, or may be increased by 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, or 0.9 mm.

Further, the second bump 310 further has an abutment surface overlapping the fourth tetrahedron 3012, and a side wall surface 312 for connecting the second friction surface 311 and the abutment surface. Wherein the abutment surface is the top surface of the second projection 310 when the second scraper 300 is in the fourth condition. When the second scraper 300 is in the third state, the side wall surface 312 abuts against the extension flap 133.

Referring to fig. 4, the area of the adjacent surface is larger than the area of the second friction surface 311, and the arrangement is as follows: in the fourth condition of the second scraper 300, the second projection 310 has a narrow bottom and wide top configuration to facilitate the passage of dirt. In addition, if the area of the second friction surface 311 is large, in the fourth state, the friction force between the second friction surface 311 and the ground is large, and the forward running resistance of the floor brush assembly 100 is large, which is disadvantageous for the operation of the floor brush assembly 100. The abutting surface is a surface body connected with the second scraping body 301, and if the area of the abutting surface is large, the connection strength between the second bump 310 and the second scraping body 301 can be improved, and the connection is stable and reliable.

When the second scraping member 300 is made of a deformable material, the second mounting portion 320 is fixedly disposed on the floor brush base. The fixing arrangement mode can be screw connection, buckle connection, glue bonding, welding and other connection modes.

Specifically, in the present embodiment, the second scraping member 300 is provided on the inner wall of the roll brush cover 130. Wherein, the inner wall of the rolling brush cover 130 is provided with an inserting part matched with the second mounting part 320, and the second scraping member 300 is mounted on the inner wall of the rolling brush cover 130 through the matching between the second mounting part 320 and the inserting part. One of the plug portion 320 and the mating portion is a clamping block, and the other is a clamping groove.

The second mounting portion 320 is integrally disposed with the second scraping body 301, so that the number of parts is reduced, and the processing process is simplified, and the structure is simple and compact.

In this embodiment, when the second scraping member 300 is made of hard material, the second scraping member 300 is hinged to the bottom of the ground brush base body by the second mounting portion 320, wherein the driving mechanism is connected to the second scraping body 301, and the second scraping body 301 can be rotated about the hinge shaft by the driving of the driving mechanism. The driving mechanism can be an air cylinder or other mechanisms with linear reciprocating motion functions.

Specifically, when the floor brush assembly 100 moves forward, the second scraping body 301 swings rearward about the hinge shaft of the second scraper 300 as a rotation center after receiving the force provided by the driving mechanism; when the floor brush assembly moves rearward, the second scraping body 301 swings forward about the hinge shaft of the second scraping member 300 as a rotation center after receiving the force provided by the driving mechanism.

In order to limit the swing angle of the second scraping member 300, a stopper 400 is provided on the floor brush base body. Referring to fig. 13 and 14, the number of the limiting blocks 400 may be one or two. When the number of the limiting blocks 400 is a pair, as shown in fig. 13, one of the limiting blocks 400 is disposed on the ground brush base body and located on the side of the second mounting portion 320 away from the rolling brush 110, for limiting the swinging angle of the second scraping member 300 when swinging forward; the other limiting block is disposed on the ground brush base body and located on the side of the second mounting portion 320 close to the rolling brush 110, and is used for limiting the swing angle of the second scraping member 300 when the second scraping member swings backwards.

When the number of the stoppers 400 is one, as shown in fig. 14, the stoppers 400 have a second stopper surface 420 on the side close to the roller brush 110 and a first stopper surface 410 on the side far from the roller brush 110. The second scraper 300 abuts the first limiting surface 410 when the second scraper 300 swings forward, and the second scraper 300 abuts the second limiting surface 420 when the second scraper 300 swings backward.

When the second scraping member 300 is hinged to the bottom of the floor brush base body by the second mounting portion 320, the second mounting portion 320 is provided in two arrangements as follows.

In an arrangement scheme, as shown in fig. 14, the second mounting portion 320 is a slot, a shaft body 500 matched with the slot is disposed at the bottom of the ground brush assembly 100, and a notch for the shaft body 500 to be clamped is disposed on a circumferential slot wall of the slot. The axis of the shaft 500 extends along the length direction of the second scraping member 300, the center line of the slot extends along the length direction of the second scraping member 300, and the axis of the shaft 500 is coaxially distributed with the center line of the slot.

In another arrangement, the second mounting portion 320 is a pin, and a pin hole (not shown) that mates with the pin is provided at the bottom of the ground brush assembly 100.

It should be understood that the above-mentioned arrangement of the second mounting portion 320 includes, but is not limited to, the above-mentioned two arrangements, and other arrangements capable of enabling the second scraping member 300 to be rotatably disposed on the floor brush assembly 100 are not described herein.

In this embodiment, referring to fig. 1 and 12, the floor brush assembly 100 further includes a first scraping member 200 extending along the axial direction of the rolling brush 110, and the first scraping member 200 is disposed at the bottom of the floor brush base body and is located behind the rolling brush 110. The first scraper 200 forms a suction opening 170 for the floor brush base body with the roller brush 110. When the brush assembly 100 is in operation, the first scraper 200 is in contact with the ground for scraping dirt. The working process comprises the following steps: advancing process, backing process, advancing and backing process.

In this embodiment, the first scraper member 200 has two structures: in the first structure, the first scraping member 200 is a sheet body, and the first scraping member 200 is abutted against the ground during the forward or backward movement of the floor brush assembly 100, so as to scrape off dirt on the ground; in the second structure, as shown in fig. 6 to 11, at least two first protrusions 210 are provided on the surface of the first scraping member 200 away from the side of the rolling brush 110, and the first protrusions 210 are spaced apart in the longitudinal direction of the first scraping member 200, and a gap between adjacent first protrusions 210 forms a first channel H1 through which dirt is allowed to pass, so that the dirt reaches the suction port 170.

The first structure is different from the second structure in that: the first bump 210. Specifically, in the first configuration, the first projection 210 is not provided on the first scraper 200; in the second configuration, the first scraper 200 is provided with a first projection 210. By providing the above-mentioned first projection 210, dirt on the side of the first scraper 200 remote from the suction opening 170 during the rearward movement of the floor brush assembly 100 can be sucked by the first scraper 200 and subsequently by the suction opening, thereby avoiding the formation of a dirt strip on the side of the first scraper 200 remote from the suction opening 170.

The first projection 210 is provided on the first scraper 200 as will be described below. Referring to fig. 10 and 11, the first scraping member 200 includes a first scraping body 201 disposed on the base of the floor brush and the first protrusion 210 disposed on the first scraping body 201. The first scraping body 201 is in a sheet shape, and the first protrusions 210 are distributed at intervals along the length direction of the first scraping body 201.

The top (ground-away side) of the first scraping body 201 is provided with a first mounting portion 230 for connection with the ground brush base body, and the first scraping body 201 further has a first abutting portion for abutting against the ground, the first abutting portion being distributed opposite to the first mounting portion 230.

In this embodiment, when the ground brush assembly 100 moves backward, the first scraping member 200 is in the second state when the first scraping body 201 swings forward under the action of an external force to make the first protrusion 210 contact with the ground. When the floor brush assembly 100 moves forward, the first scraping body 201 swings backward under the action of an external force, so that the first abutting portion abuts against the ground, and the first scraping member 200 is in the first state. As can be seen from the above, the first scraper member 200 is capable of being changed between the first state and the second state by an external force.

In this embodiment, the material of the first scraper 200 affects the type of external force. When the first scraping member 200 is made of a deformable material, the external force is a friction force between the first scraping body 201 and the ground; when the first scraping member 200 is made of a hard material, the external force is a force provided by an external force mechanism (not shown) provided on the base body of the floor brush, and the force provided by the external force mechanism is configured to drive the first scraping member 200 to switch between the first state and the second state.

When the first scraping element 200 is made of a deformable material, the first mounting portion 230 is fixedly secured to the base of the brush. The fixing arrangement mode can be screw connection, buckle connection, glue bonding, welding and other connection modes. When the first scraper 200 is made of a hard material, the first mounting portion 230 is hinged to the base of the floor brush. The first scraping member 200 is rotatable about its hinge shaft by the above-mentioned external force mechanism. When the first scraper 200 is made of a hard material, the structure of the first mounting portion 230 may refer to the structure of the second mounting portion 320, which will not be described in detail herein.

In this embodiment, the first scraper member 200 is preferably made of a deformable material. Wherein the first scraper member 200 is made of a deformable material means that: the first scraping body 201 and the first bump 210 are both made of a deformable material. The deformable material may be rubber, silicone, or the like, and thus can be deformed by friction. The following description will be made with reference to the first scraper member 200 being made of a deformable material.

With continued reference to fig. 7, the first scraping body 201 has a first face 2011 on the side closer to the roller brush 110 and a second face 2012 on the side farther from the roller brush 110. That is, the first and second facings 2011, 2012 are disposed back-to-back, wherein the first bump 210 is disposed on the second facings 2012.

Further, the first contact portion has a contact surface capable of contacting the ground, and the contact surface of the first contact portion is at least one of the first surface 2011 and a bottom adjacent surface between the first surface 2011 and the second surface 2012.

Preferably, the abutting surface of the first abutting portion is the first surface 2011, and when the first surface 2011 abuts against the ground, the deformation amount of the first scraping body 201 is large, so that the first scraping body 201 can be tightly attached to the ground, and therefore residual water and dirt on the ground can be better pushed towards the suction port and the rolling brush 110, and the residual water and dirt residual amount on the ground can be reduced to the greatest extent.

Referring to fig. 7 to fig. 9, when the contact surface of the first contact portion is the first surface 2011, scraping strips 220 distributed along the length direction of the first surface 2011 are formed on the first surface 2011, and the scraping strips 220 are protruding on the first surface 2011 for scraping stubborn stains on the ground. The structural strength of the first scraping body 201 at the scraping strip 220 can be increased by arranging the scraping strip 220, and therefore, the area of the first scraping body 201 at the scraping strip 220 is difficult to deform compared with other areas, so that the scraping strip 220 is clung to the ground, and stubborn stains on the ground can be scraped.

Specifically, the outer peripheral surface of the wiper strip 220, which is a surface body that is not coplanar with the first surface body 2011, includes a third friction surface 221 and an extension surface 222. In the present embodiment, the extension surface 222 is distributed farther from the bottom edge of the wiper strip 220 than the third friction surface 221. In the first state, the third friction surface 221 of the wiper strip 220 abuts against the ground, and the extension surface 222 is gradually away from the ground.

Wherein the third friction surface 221 is abutted against the ground for scraping the ground; the extended surface 222 is gradually far away from the ground to form an avoidance space, so that dirt is sucked by the suction port.

In the present embodiment, when the first scraper 200 is in the first state and the abutment surface of the first abutment portion is the first surface 2011, at least the scraper bar 220 abuts against the ground. The above can be understood as two cases, the first case, when the first scraper 200 is in the first state and the abutment surface of the first abutment portion is the first surface 2011, the scraper bar 220 abuts against the ground; in the second case, when the first scraper 200 is in the first state and the contact surface of the first contact portion is the first surface 2011, the scraper bar 220 and the first surface 2011 are respectively in contact with the ground.

In this embodiment, as shown in fig. 11, the first bump 210 has a first friction surface 211 far from the first scraping body 201, and when the first scraping member 200 is in the second deformed state, the first friction surface 211 abuts against the ground. The distance between the first friction surface 211 and the first scraping body 201 is a distance L1, and the distance L1 is the height of the first channel H1.

When the floor brush assembly 100 moves forward, dirt on the floor reaches the roller brush 110 through the second passage H2 to be sucked by the roller brush 110 and the suction port 170, and at the same time, the first abutting portion of the first scraper 200 abuts against the floor to scrape off the water and dirt on the floor behind the roller brush 110. In the above process, the first scraping member 200 is mainly used for scraping off water stains remaining on the ground. The term "mainly used for scraping off water stains remaining on the ground" is understood here as: during forward movement of the floor brush assembly 100, most dirt is sucked up by the suction opening, and even if dirt remains on the floor, a small amount of minute dirt is left. Therefore, the first scraping member 200 is mainly used for scraping off the residual water on the ground to reduce the amount of residual water on the ground.

Specifically, during the forward movement of the floor brush assembly 100, the first scraping member 200 can push the residual water on the floor forward, whereby the residual water is either sucked by the suction port or sucked by the roller brush 110, and the cleaning effect is effectively improved while reducing the residual water amount on the floor.

When the brush assembly 100 moves backward, the second abutting portion of the second scraping member 300 abuts against the ground to scrape dirt on the ground, the first protrusion 210 abuts against the ground, and the first channel H1 is used for passing dirt (mainly residual water). In the above process, the first channel H1 is mainly used for passing residual water because: when the brush assembly 100 is retracted, water stains primarily remain on the floor as the floor is cleaned.

Considering that the first passage H1 mainly passes the residual water, the height L1 of the first passage H1 is smaller than the height L2 of the second passage H2. In this embodiment, the height L1 of the first channel H1 is 1mm or less. In this embodiment, the height L1 of the first channel H1 may be 0.5mm, 1mm, or the like, or may be increased in units of 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm between 0.1mm and 1mm.

In this embodiment, the second bump 310 is distributed near the bottom edge of the second scraping body 301; the first bumps 210 are distributed near the bottom edge of the first scraping body 201. For convenience of explanation, the second bump 310 will be described as an example. When the second protrusions 310 are distributed near the bottom edge of the second scraping body 301, in the fourth state, a sufficient gap between the bottom edge of the second scraping body 301 and the floor surface can be ensured for dirt to pass through.

Conversely, if the second bump 310 is not distributed near the bottom edge of the second scraping body 301, in the fourth state, the bottom edge of the second scraping body 301 may be close to the ground, and the distance between the bottom edge of the second scraping body 301 and the ground is relatively small, which affects the dirt passing.

The bottom of the ground brush base body is further provided with a main roller 140 and an auxiliary roller 150, and after a user applies forward thrust to the ground brush assembly 100, the ground brush assembly 100 moves forward under the action of the main roller 140 and the auxiliary roller 150.

When the user pulls the floor brush assembly 100 upward, the second scraper 300 and the first scraper 200 are suspended, and at this time, the second scraper 300 and the first scraper 200 are in a natural state.

In the natural state of the second scraper 300 and the first scraper 200, the bottom edges of the second scraper 300 and the first scraper 200 are lower than the lowest ends of the main roller 140 and the auxiliary roller 150, so as to ensure that the first scraper 200 and the second scraper 300 can sufficiently abut against the ground.

In order to improve the sealing performance of the rolling brush chamber of the floor brush assembly 100, a sealing member 131 is disposed between the rolling brush cover 130 and the main housing 120. The sealing member 131 is positioned above the first and second scraping members 200 and 300 and at the top of the rolling brush chamber 160 to reduce or eliminate a gap between the main housing 120 and the rolling brush cover 130, thereby improving the sealing performance of the top of the rolling brush chamber 160 and thus improving the vacuum degree of the rolling brush chamber 160. Wherein, the gap is a gap space communicated with the outside by the rolling brush cavity.

In this embodiment, when the floor brush assembly 100 moves backward, the first scraping member 200 and the second scraping member 300 are respectively abutted against the floor, and the first scraping member 200, the second scraping member 300 and the sealing member 131 together form a sealing structure acting on the rolling brush chamber 160 to increase the vacuum degree of the rolling brush chamber 160, thereby effectively improving the dirt absorbing capacity at the suction port 170, and having the advantage of good cleaning performance.

In particular, in the case where the first scraping member 200 is provided with the first protrusions 210, and when the roll brush assembly 100 moves on a carpet, particularly, during the backward movement of the roll brush assembly 100, since the height of the first channels H1 formed between the first protrusions 210 is small, the first channels H1 can be filled with the fluff of the carpet surface, and the vacuum degree of the roll brush chamber 160 is high.

It will be appreciated that when the first scraper 200 is not provided with the first bump 210, the vacuum level of the roller brush chamber 160 is higher than when the first bump 210 is provided.

Referring to fig. 2, the rolling brush body 110 is disposed at a front side of the main base 120 along the advancing direction of the floor brush assembly 100. The main housing 120 has two supporting ends 121, and both ends of the rolling brush 110 are respectively supported on the two supporting ends 121. One of the support ends is a driving end, is connected with a motor arranged in the ground brush assembly 100, and provides power for the rotation of the rolling brush 110; the other of which is a driven end for supporting the roll brush 110.

As for the installation position of the seal member 131, there are three installation positions as follows: first, the sealing member 131 is provided on the inner wall of the roll brush cover 130; second, the sealing member 131 is disposed on the main housing 120; third, the rolling brush cover 130 and the main housing 120 are provided with the sealing member 131.

In this embodiment, as shown in fig. 5, preferably, the sealing member 131 is disposed on the inner wall of the roller brush cover 130 and is distributed near the end of the roller brush 110. Wherein the sealing members 131 are symmetrically distributed and extend around the circumferential direction of the roll brush 110. The inner wall of the rolling brush cover 130 is provided with a pair of bearing parts 132, the bearing parts 132 are provided with clamping grooves, and the sealing piece 131 is arranged on the bearing parts 132 through the clamping grooves. The bearing portion 132 has a rib shape.

Having fully described the structure of the floor brush assembly 100 above, one skilled in the art will understand the following operation:

when the floor brush assembly 100 moves forward, the second protrusions 310 of the second scraping member 300 abut against the floor, the first surface 2011 of the first scraping body 201 abuts against the floor, and at this time, the gaps between the second protrusions 310 allow water stains and/or dirt to pass through to be sucked by the suction port, and the first scraping body 201 can push the water stains and/or dirt on the floor to the suction port (mainly push the water stains remaining on the floor to the suction port);

when the floor brush assembly 100 runs backward, the third surface of the second scraping member 300 is abutted against the ground, and the first protruding block 210 is abutted against the ground, at this time, the second scraping member 300 can push the water stain on the ground to the side of the rolling brush 110 for sucking by the suction port, and the gap between the first protruding blocks 210 allows the water stain on the ground to pass through for sucking by the suction port;

Therefore, the soil strips which cannot be sucked by the floor brush assembly 100 can be effectively avoided from occurring on the ground, and the residual water quantity on the ground is reduced, so that the floor brush assembly has the advantage of good cleaning effect.
