The utility model is further described below with reference to the drawings and examples.

According to some embodiments of an aspect of the present utility model, as shown in fig. 1, the floor brush assembly comprises a housing 1, an air inlet chamber 26 formed at the bottom of the housing 1, a first rolling brush 21 mounted at the front of the housing 1, a V-shaped first air guiding groove 241 formed at the bottom of the housing 1, the bottom of the first air guiding groove 241 being of an open structure and facing the surface to be cleaned, a wide end opening toward the first rolling brush 21, a narrow end communicating with the air inlet chamber 26, and an auxiliary roller 27 for supporting a machine body together with the first rolling brush 21 being provided at the rear of the housing 1;

The two side walls of the V-shaped first air guide groove 241, namely the lower edges of the two V-shaped arms thereof, are provided with V-shaped first scraping strips 251, the first scraping strips 251 are made of flexible wear-resistant materials, such as silica gel, rubber and the like, the lower edges of the first scraping strips 251 are in contact with the surface to be cleaned, are used for removing dirt and sewage attached to the surface to be cleaned when the floor brush assembly advances, guide and collect the dirt and sewage near the narrow end of the first air guide groove 241, and can achieve larger suction force due to small air inlet area near the narrow end and high air flow speed, so that the dirt and sewage can be sucked into the air inlet cavity 26 more easily and collected in the dirt collecting container;

When the floor brush assembly retreats, residual dirt and sewage which is not sucked temporarily remains on the surface to be cleaned, is collected and limited near the wide end of the first air guide groove 241 by the roll brush 21, and the foregoing cleaning process is repeated again when the floor brush assembly advances next time;

In the forward and backward process of the floor brush assembly, since the first air guide groove has no bottom plate and is an open structure facing downward, even if there is residual dirt and sewage, the dirt and sewage is not left inside the air guide groove, but is limited on the cleaned surface between the wide end and the narrow end of the first air guide groove 241, and is gathered again to be sucked into the air inlet chamber 26 in the reciprocating cleaning process.

It will be appreciated that in other embodiments according to the present utility model, the V-shaped wind guide grooves and V-shaped wiper strips described above may also be arcuate wind guide grooves and arcuate wiper strips, which should be considered equivalent alternatives to V-shaped wind guide grooves and V-shaped wiper strips, as well as within the scope of the present utility model.

Further, the first rolling brush 21 is controlled by a one-way clutch, which can only rotate in a single direction, and the one-way clutch can be a one-way bearing arranged at the shaft end of the first rolling brush 21 or other mechanisms with one-way non-return function;

When the shell 1 moves forwards, the unidirectional bearing of the first rolling brush 21 is controlled to be in an overrun state, the first rolling brush 21 rotates under the action of friction force between the rolling brush surface and the surface to be cleaned and rolls over the surface to be cleaned, garbage and sewage enter the first air guide groove 241 behind the first rolling brush 21, and are guided and collected near the narrow end of the first air guide groove 241 under the synergistic effect of the first scraping strip 251 and the air flow and then are sucked into the air inlet cavity 26;

Conversely, when the housing 1 moves rearward, the one-way bearing of the first roller brush 21 is controlled to be in a non-return state, so that the first roller brush 21 stops rotating, and the surface thereof rubs and wipes the surface to be cleaned. Because the first rolling brush 21 is in a stalling state and is in sliding friction with the surface to be cleaned, and the first rolling brush 21 and the auxiliary roller 27 positioned at the rear part of the shell jointly support the weight of the machine body, compared with an electric rolling brush with the surface of which only brush hair is contacted with the ground, the rolling brush surface has larger downward pressure on the surface to be cleaned, has better cleaning effect on stubborn stains, wet hair and the like, and meanwhile, because the first rolling brush is passively rotated, no motor drive is needed, the cleaning tool can have longer endurance time.

It will be appreciated that in other embodiments, the first roller brush 21 may also be an electric roller brush to accommodate a cleaning scenario suitable for an electric roller brush.

The floor brush assembly according to some embodiments of an aspect of the present utility model, as shown in fig. 2 to 4, includes a housing 1, and first and second rolling brushes 21 and 22 installed in front and rear directions of the housing 1;

At the bottom of the housing 1, two air guide grooves, a first air guide groove 241 and a second air guide groove 242, are formed, each of which is V-shaped in shape, and the wide ends and the lower sides thereof are opened, and an air inlet chamber 26 communicating with the two narrow ends is formed between the two narrow ends thereof;

Specifically, the wide end of the first air guiding groove 241 faces the first rolling brush 21, the narrow end faces the air inlet cavity 26 and is communicated with the air inlet cavity, the bottom of the air guiding groove is open and faces the surface to be cleaned, and the lower edges of the two side walls of the air guiding groove are provided with V-shaped first scraping strips 251;

The second wind guiding groove 242 has a wide end facing the second rolling brush 22 and a narrow end facing the wind inlet chamber 26 and communicating with the same, the bottom of the wind guiding groove is also open and facing the surface to be cleaned, the lower edges of the two side walls of the wind guiding groove are provided with V-shaped second scraping strips 252, the lower edges of the first scraping strips 251 and the second scraping strips 252 are contacted with the surface to be cleaned, and at least the contact parts of the first scraping strips 251 and the second scraping strips 252 with the surface to be cleaned are made of flexible wear-resistant materials, such as silica gel, rubber or collodion materials.

When the floor brush assembly is used for cleaning, when the shell moves in a certain direction, air flows enter through the wide end of the air guide groove positioned in the direction and are gathered by the V-shaped air guide groove, and as the bottom plate is not arranged below the air guide groove and is of an open structure, garbage and sewage on the surface to be cleaned are guided and gathered near the air inlet cavity under the scouring of the air flows and the pushing and scraping effects of the V-shaped scraping strips, and as the air flow speed near the air inlet cavity is faster, the suction force is more concentrated, and the gathered garbage and sewage can be sucked into the sewage suction channel more easily;

because the lower part of the air guide groove is of an open structure, even if residual garbage and sewage exist, the garbage and sewage can not remain in the air guide groove, but are gathered and sucked again along with the reciprocating movement of the ground brush component.

When the housing 1 is moved forward during cleaning operation, as shown in fig. 6, the friction between the friction member 264 and the surface to be cleaned causes the partition 263 to move backward relative to the housing 1, and at this time, the gap between the rear inclined surface 2632 of the partition 263 and the rear wall surface 262 of the air intake chamber 26 is reduced or closed, and the gap between the front inclined surface 2631 and the front wall surface 261 of the air intake chamber 26 is increased, so that a first dirt suction channel 2610 is formed in the air intake chamber 26, which is inclined with the opening directed forward;

In contrast, when the housing 1 moves backward, as shown in fig. 7, the friction of the friction member 264 with the surface to be cleaned causes the partition 263 to move forward relative to the housing 1, the gap between the front inclined surface 2631 of the partition 263 and the front wall surface 261 of the air intake chamber 26 decreases or closes, the gap between the rear inclined surface 2632 and the rear wall surface 262 of the air intake chamber 26 increases, and thus a second dirt suction passage 2620 is formed in the air intake chamber, which is inclined with the opening directed backward.

Because the air inlet cavity is not provided with a fixed dirt sucking port and a dirt sucking channel, the friction piece is rubbed with the cleaned surface to drive the separating piece to move back and forth, and the single dirt sucking channel facing different directions is dynamically constructed by changing the relative positions of the front and back inclined planes of the separating piece and the front and back walls of the air inlet cavity, so that the total air inlet area is not increased under the condition that the proper air inlet area of the dirt sucking channel facing a certain direction is ensured, the occupied space of the traditional double suction ports is reduced, the problem of scattered suction force of the double suction ports is avoided, and the dirt sucking effect is enhanced;

Meanwhile, the air inlet cavity with the narrow upper part and the wide lower part and the partition piece with the inclined plane naturally form an inclined dirt sucking channel, which is beneficial to smooth passage of air flow, reduces air flow resistance, ensures that sewage and garbage can be lifted along the inclined plane of the partition piece, and has better dirt sucking effect on sewage and heavier garbage;

The partition piece is directly rubbed with the surface to be cleaned through the friction piece combined below, the partition piece is driven to move forwards and backwards, the structure is simple, the reliability is high, and the device is suitable for being arranged in an air inlet cavity with limited space.

Further, according to some embodiments of an aspect of the present utility model, the first rolling brush 21 is driven to rotate by the motor, the second rolling brush 22 is controlled by the one-way clutch, so that the rolling brush can only rotate in a single direction, and the rotation direction of the first rolling brush 21 is opposite to that of the second rolling brush 22;

As shown in fig. 3, an auxiliary roller 27 is arranged on the bottom surface of the shell 1, the barrel of the first rolling brush 21 is arranged in a suspending way, only the surface bristles contact the surface to be cleaned, the gravity center of the shell 1 falls between the second rolling brush 22 and the auxiliary roller 27, and the main weight of the shell is supported by the second rolling brush 22 and the auxiliary roller 27;

In the cleaning process, when the shell 1 moves towards the first rolling brush 21, the first rolling brush 21 rotates to lift dirt on the surface to be cleaned, the dirt is sucked into the dirt collecting container through the air inlet cavity 26, at the moment, the one-way clutch keeps the second rolling brush 22 non-return, and the surface of the second rolling brush 22 rubs with the surface to be cleaned and wipes the surface to be cleaned;

When the casing 1 moves towards the second rolling brush 22, the first rolling brush 21 continues to rotate, and at the moment, the one-way clutch of the second rolling brush 22 is controlled to be in an overrunning state, and the second rolling brush 22 passively rotates by utilizing friction force between the surface of the second rolling brush and the surface to be cleaned.

Specifically, the one-way clutch is preferably a one-way bearing arranged at the shaft end of the second rolling brush 22, and has the advantages of small volume, low noise, reliable control and direct selection of standard components, and of course, other mechanisms with one-way control functions such as a ratchet wheel and the like can be selected.

Because the first rolling brush 21 is an electric rolling brush rotating at a high speed, dirt and sewage can be hoisted, and better dirt sucking effect is achieved under the same suction strength and air inlet structure. Meanwhile, in order to avoid the influence of the high-speed rotating rolling brush on the machine body, the electric rolling brush is usually installed with a certain gap with the surface to be cleaned, and the surface brushing is used for touchdown cleaning the surface to be cleaned, when the ground brush moves along a cleaning path, the brushing on the surface of the rotating rolling brush can roll in sewage on the surface to be cleaned, and the sewage can not be pushed forward like a second rolling brush which is closely attached to the surface to be cleaned;

The second rolling brush is controlled by the one-way clutch, is in a non-return state when moving towards the first rolling brush, and the rolling brush surface stopped rotating is clung to and wipes the cleaned surface due to the main weight of the shell body supported by the second rolling brush and the auxiliary roller, so that the cleaned surface is pressurized, the cleaning effect is better for cleaning stubborn stains and wet hair when the cleaning cloth wipes the ground, the first rolling brush can generate forward power, the friction resistance between the second rolling brush and the cleaned surface can be overcome, and the forward movement of the ground brush assembly is more labor-saving;

In addition, because the second rolling brush has a better cleaning effect on stubborn stains and residual sewage which can be erased by pressurizing, the first rolling brush only needs to take on the task of cleaning the dirt and sewage which is not firmly attached to the surface to be cleaned, the installation height of the first rolling brush can be properly increased, the contact pressure between the rolling brush bristles and the surface to be cleaned can be reduced, the wear of the rolling brush bristles rotating at a high speed is reduced, the service life of the rolling brush is prolonged, meanwhile, the power consumption of the rolling brush is reduced, and the moving resistance caused by the first rolling brush rotating reversely is also reduced when the rolling brush moves towards the second rolling brush;

Therefore, under the cooperation of the two different types of rolling brushes, the rolling brushes are mutually supported in function, the defects of the rolling brushes are overcome, and better cleaning effect and better use experience are achieved compared with a single type of double-rolling-brush ground brush assembly.

Further, as shown in fig. 5, a rotatable wringing roller 200 is further disposed behind the first rolling brush 21, the wringing roller 200 contacts and extrudes the surface of the first rolling brush 21, and when the first rolling brush 21 rotates, the wringing roller 200 is driven to rotate, and meanwhile, the wringing roller 200 extrudes the water in the bristles of the first rolling brush 21.

Compared with the wiper blade in the prior art, the round rotatable wringing roller has smaller friction resistance with the rolling brush while maintaining the wringing pressure, so that the power consumption during the rotation of the electric rolling brush can be reduced, or when the rolling brush is a rolling brush which rotates passively, the friction force between the rolling brush and a wringing piece can be prevented from being larger than the friction force between the rolling brush and a surface to be cleaned, thereby leading to the blocking and stopping of the rolling brush, reducing the abrasion of the rolling brush and prolonging the service life of the rolling brush.

Further, in accordance with some embodiments of the present utility model, electrically driven road wheels are also included.

The electrically driven travelling wheels can replace the auxiliary rollers 27 shown in fig. 1 and 3 to support the shell and provide assistance, or the cleaning robot can have the capabilities of travelling, backing and steering through the rotation of the travelling wheels when the ground brush assembly is used as a cleaning robot part.

Further, according to some embodiments of the utility model, at least one of the first and second roller brushes is a track roller brush.

Compared with the cylindrical rolling brush, the crawler-type rolling brush has larger contact area with the surface to be cleaned, is not easy to wind hair and is not easy to miss dirt.

According to an embodiment of an aspect of the utility model, there is provided a cleaning apparatus comprising a floor brush assembly as claimed in any one of the preceding claims.

The cleaning device can be any surface cleaning device using the floor brush assembly provided by the utility model, including but not limited to a dust collector, a floor scrubber, a glass cleaner, a cleaning robot and the like;

compared with the prior art, the cleaning equipment applying the floor brush assembly provided by the utility model has the characteristics of simple structure, small volume, light weight, good cleaning effect, easiness in cleaning, multiple purposes and the like.
