Referring to fig. 1 and 2, some embodiments of the present application provide a floor brush 100 including a housing 110, a rolling brush 120, and a comb 140. The rolling brush 120 is disposed in the housing 110, and a portion of the rolling brush 120 extends out of the housing 110, and bristles 121 are covered on the outer circumference of the rolling brush 120. The comb 140 is disposed in the housing 110, and has one end configured with a plurality of comb parts s, at least part of which protrude into the bristles 121 to comb the bristles 121.

The housing 110 is a carrier for carrying the structures of the rolling brush 120 and the combing members 140, and may be, but not limited to, a plastic member. The housing 110 may be provided with a rolling brush cavity 111, the rolling brush cavity 111 is configured to be disposed facing the side opening of the surface to be cleaned, the rolling brush 120 is installed in the rolling brush cavity 111, and a portion of the rolling brush 120 extends out of the housing 110 through the opening of the rolling brush cavity 111 for contacting with the surface to be cleaned (e.g., the floor) to clean the surface to be cleaned.

Understandably, the rolling brush 120 is rotatably installed in the housing 110 (specifically, the rolling brush cavity 111) along its own axial direction Z, which in the embodiment of the present application is referred to as the axial direction Z of the rolling brush 120. The rotatable connection between the rolling brush 120 and the housing 110 can be realized by, but not limited to, providing a bearing on the housing 110, and the rolling brush 120 has a rotating shaft mounted on the bearing. A driving mechanism 160 for driving the roll brush 120 to rotate is provided in the housing 110. The driving mechanism 160 may include a motor 161 and a transmission structure 162, and the motor 161 is in transmission connection with the roller brush 120 through the transmission structure 162 and drives the roller brush 120 to rotate. The transmission structure 162 may be a belt transmission structure, a chain transmission structure, a gear transmission structure, or the like. The specific configuration of the drive mechanism 160 is not particularly limited in the embodiments of the present application.

The brush bristles 121 are disposed on the outer circumference of the roller brush 120 to rub against a surface to be cleaned, thereby cleaning the surface to be cleaned. Generally, one end of the brush 121 is fixed and the other end is freely arranged, when the brush 121 works on a surface to be cleaned, the free end of the brush 121 can be pressed and bent by the cleaning surface, and after a long-time cleaning operation, the brush 121 is easy to fall to one side and cannot effectively contact with the surface to be cleaned.

The bristles 121 may be made of plastic, rubber, or the like, and are not particularly limited. The brush bristles 121 may be disposed on the entire outer circumference of the roll brush 120, or may be disposed on a part of the outer circumference of the roll brush 120, and the specific arrangement thereof is not limited in the embodiment of the present application. Specifically, the rolling brush 120 may include a roller 122 and bristles 121, the bristles 121 being disposed on the roller 122, and the roller 122 being drivingly connected to the driving mechanism 160. The roller 122 may be, but is not limited to, a plastic piece.

The comb 140 has a function similar to a "comb", and is formed at one end thereof with a plurality of comb portions s, and only at least a portion of the comb portions s protrude into the bristles 121, enabling combing of the bristles 121. Understandably, the brush bristles 121 of the roll brush 120 may be inserted between the comb teeth s and pass through the comb teeth s during the rotation. When the brush 121 is inserted between the comb-tooth portions s, the brush rubs or collides with the comb-tooth portions s to change the extending direction, and the falling state of the brush 121 is changed, so that the brush 121 can be unfolded and combed.

It should be emphasized that, in the present embodiment, the bristle 121 side lodging mainly means that the free end of the bristle 121 is bent towards the downstream side of the rotation direction of the rolling brush 120, and the comb 140 in the present embodiment can rebinn the bristle 121 with one side lodging by friction, collision, etc. between the comb teeth s and the bristle 121, so as to relieve the degree of bending of the bristle 121, so that the bristle 121 is unfolded along the set extending direction (i.e. the extending direction of the free end of the bristle 121 in the initial stretched state), and when the bristle 121 is in the unfolded state, the bristle 121 can be effectively contacted with the surface to be cleaned.

The sectional shape of the comb-teeth s in the first plane perpendicular to the radial direction of the roll brush 120 may be circular, rectangular, polygonal, or the like, and is not particularly limited. The cross-sectional shape of the comb-teeth s may be circular, triangular, or the like in a plane perpendicular to the first plane. The comb teeth s may be made of elastic material such as rubber, silicon gel, etc. The comb teeth s may be made of hard materials such as plastic and metal. The specific form and material of the comb teeth s are not limited in the embodiments of the present application. The attachment of comb 140 to housing 110 may be, but is not limited to, a fastening connection, a snap connection, or the like.

In the floor brush 100, when the floor brush is actually used, the part of the bristles 121 of the roll brush 120 is easily laid down toward one side after cleaning the dirt adhered to the surface to be cleaned, and when the part of the bristles 121 passes through the combing member 140, the part of the bristles 121 is spread out in a direction away from the laying direction without being laid down toward one side under combing of the combing part s, and when the part of the bristles 121 again contacts the surface to be cleaned, the part of the bristles 121 can effectively contact the surface to be cleaned.

Compared with the prior art, according to the floor brush 100 provided by the embodiment of the application, when the bristles 121 clean the cleaned surface and one side of the cleaned surface falls down, the bristles 121 can be kept in the unfolded state under the combing action of the comb-tooth part s, and when the bristles 121 are contacted with the cleaned surface again to clean the cleaned surface, the bristles 121 can be effectively contacted with the cleaned surface, so that the cleaning effect of the bristles 121 is greatly improved.

Illustratively, in some embodiments, referring to fig. 1, the housing 110 is further provided with a collecting channel 112, and when the collecting channel 112 is connected to an external negative pressure source (e.g., a blower), the collecting channel 112 can suck away the dirt scraped off by the scraping bar 130, the dirt peeled off by the bristles 121 on the cleaned surface, and the like. Further, the housing 110 may further be provided with an air exhaust channel 113, when the floor brush 100 is coupled to a dirt collecting device (not shown), the air exhaust channel 113 is communicated with a fan in the dirt collecting device, and dirt enters the dirt collecting device through the collecting channel 112 and the air exhaust channel 113 for collection. The sewage collecting device may include a sewage tank communicating the blower with the air-extracting passage 113, and the sewage discharged from the air-extracting passage 113 is retained in the sewage tank. The dirt collecting device can also comprise a clean water tank, when the dirt collecting device is matched and connected with the floor brush 100, the clean water tank can provide clean water for the floor brush 100, and the clean water can be sprayed to a cleaned surface through the spraying head on the floor brush 100, so that the wet cleaning of the ground is realized. Further, the floor brush 100 is also provided with a scraper 180, and the scraper 180 is disposed at the entrance of the collection channel 112 and is used to abut against the surface to be cleaned. The scraper 180 is provided to scrape off dirt on the surface to be cleaned and to guide the dirt to the collection passage 112. Further, the floor brush 100 further comprises a traveling mechanism 170, and the traveling mechanism 170 comprises traveling wheels.

In some embodiments, the comb-teeth s include a plurality of comb-teeth s, which are sequentially arranged in a direction parallel to the axial direction Z of the roll brush 120, and a gap through which the bristles 121 are inserted is defined between adjacent comb-teeth s.

In the direction parallel to the axial direction Z of the rolling brush 120, a gap is formed between adjacent comb tooth parts s, when the rolling brush 120 rotates, part of the bristles 121 directly pass through the penetrating gap, and part of the bristles 121 contact with the comb tooth parts s and are stressed to change the lodging direction, so that the bristles 121 are unfolded to a certain degree instead of being lodged on one side.

At the moment, the comb teeth are simple in structure and convenient to manufacture.

Of course, in other embodiments, the arrangement direction of the comb-teeth s may not be limited to being arranged in a direction parallel to the axial direction Z of the roll brush 120, but may be provided in a direction at an acute angle to the axial direction Z. In addition, the comb-teeth s may be arranged in one or more rows parallel to the axial direction Z of the roll brush 120 (each row of comb-teeth s is spaced apart in a direction perpendicular to the axial direction Z), and the number of the comb-teeth s in each row may be equal or different. The comb teeth s may be identical or different in shape. The arrangement of the comb teeth s is flexible, and is not particularly limited in the embodiment of the present application.

In some embodiments, referring to fig. 3, the floor brush 100 further comprises a driving structure 150, the driving structure 150 is connected to the combing members 140, and the driving structure 150 is used for driving the combing members 140 to reciprocate in a direction parallel to the axial direction Z of the roller brush 120.

A driving structure 150 is provided on the housing 110 for driving the comb 140 to reciprocate in a direction parallel to the axial direction Z of the roll brush 120. Here, "to reciprocate in the direction parallel to the axial direction Z of the roll brush 120" means that the comb 140 has a partial displacement in the axial direction Z of the roll brush 120 during the movement. That is, the comb 140 may be reciprocally moved in a direction parallel to the axial direction Z of the roll brush 120, may be reciprocally moved in a direction crossing the axial direction Z of the roll brush 120 at an acute angle, and may even be moved in a curved line as long as there is a partial displacement in the axial direction Z of the roll brush 120.

The driving structure 150 may be a telescopic cylinder structure, a conveyer belt structure, a gear screw structure, etc., and the specific structure is not limited as long as the movement of the combing members 140 can be realized, and a person skilled in the art can perform a conventional arrangement.

When the comb 140 reciprocates in the direction parallel to the Z axis of the rolling brush 120, the bristles 121 are pushed to move in the direction parallel to the Z axis of the rolling brush 120, so that the spreading of the bristles 121 can be accelerated, and the spreading effect of the bristles 121 is excellent.

In some embodiments, referring to fig. 3, the driving structure 150 comprises a cam 151, the cam 151 being disposed in the housing 110 and rotatable with respect to the housing 110, the cam 151 having a driving surface m, the driving surface m being connected to the comb 140, the driving surface m being configured to drive the comb 140 to reciprocate in a direction parallel to the axial direction Z of the roller brush 120 during rotation of the cam 151.

The cam 151 can rotate about its own rotation center with respect to the housing 110. Alternatively, the cam 151 has a rotating shaft that is rotated by a power mechanism. The driving surface m and the combing member 140 may be connected by a fixed connection, a movable connection, an abutment, or the like, as long as the driving surface m can drive the combing member 140 to move in a direction parallel to the axial direction Z of the roll brush 120 when the cam 151 rotates.

The arrangement of the driving surface m depends on the arrangement of the cam 151. Illustratively, when the cam 151 rotates around a direction perpendicular to the axial direction Z of the roller brush 120, the driving surface m may be a circumferential surface of the cam 151, and in order to realize that the driving surface m drives the comb 140 to move, the driving surface m may be an elliptic cylindrical surface, and the comb 140 abuts against the driving surface m, and during the rotation of the cam 151, when the comb 140 switches the abutment between the short-side end surface and the long-side end surface of the driving surface m, the comb 140 may be moved in a direction parallel to the axial direction Z of the roller brush 120. Of course, the configuration of the driving surface m is not limited to the elliptic cylindrical surface as long as the combing members 140 can be driven to move in the direction parallel to the axial direction Z of the roll brush 120.

At this time, the comb 140 is driven by the cam 151 structure, and the driving structure 150 occupies a small space and has a simple structure.

Understandably, the floor brush 100 further comprises a driving mechanism 160, and the driving mechanism 160 drives the rolling brush 120 to rotate. The driving mechanism 160 may include a motor 161 and a transmission structure 162, and the motor 161 is in transmission connection with the roller brush 120 through the transmission structure 162. The transmission structure 162 may be, but is not limited to, a timing belt structure, a gear structure, a chain structure, etc., and the transmission structure 162 may be provided according to a conventional means. In one embodiment, the transmission structure 162 may be connected to the cam 151 and the motor 161, and in another embodiment, the cam 151 is connected to the roller brush 120 in a transmission manner, so that the motor 161 can be simplified by using a motor 161 to drive the roller brush 120 and the cam 151 simultaneously. The cam 151 and the roller brush 120 may rotate synchronously or asynchronously, but are not limited thereto.

In some embodiments, referring to fig. 3, the cam 151 is disposed on at least one side of the moving direction of the combing member 140 and configured to rotate around a direction parallel to the axial direction Z of the rolling brush 120, and the driving surface m is disposed on one side of the cam 151 in the axial direction Z.

The driving surface m is a surface of the cam 151 facing the comb 140, and in order to realize that the driving surface m drives the comb 140 to move, the configuration of the driving surface m may be, but is not limited to: the driving surface m is configured with a relief surface which is provided around the rotation center of the cam 151, the height of the relief surface at the rotation center of the cam 151 is uneven in the direction of its circumference, the relief surface has a high point position and a low point position, and the movement of the comb 140 in the direction parallel to the axial direction Z of the roller brush 120 is performed when the comb 140 moves from the position connected to the high point position to the position connected to the low point position during the rotation of the cam 151. Of course, the configuration of the driving surface m is not limited thereto, and a person skilled in the art can make routine arrangements.

At this time, the cam 151 is located on one side in the moving direction of the comb 140, and the surface of the cam 151 facing the comb 140 is configured as the driving surface m, and the size of the cam 151 in the axial direction Z is small, which contributes to the improvement of the space utilization rate inside the housing 110.

In some embodiments, referring to fig. 4, the comb 140 is provided with an abutting portion 142, and the abutting portion 142 abuts against the driving surface m.

The abutting portion 142 may be an abutting shaft, an abutting rod, an abutting bump, and the like, and is not limited in particular. The position of the abutment portion 142 depends on the manner of installation of the cam 151. When the cam 151 is provided on one side of the comb 140 in the axial direction Z, the abutment portion 142 is provided on one side of the comb 140 in the axial direction Z. When the cam 151 is provided corresponding to the middle position of the comb 140 in the axial direction Z, the abutment portion 142 may be provided at the middle position of the comb 140.

In this case, the comb 140 is in contact with the driving surface m by the contact portion 142, so that the connection method is simple and the manufacturing cost is low.

Understandably, the abutting portion 142 is held against the driving surface m during the movement of the comb 140. In order to keep the abutting portion 142 abutting against the driving surface m, there may be adopted: two convex parts and two abutting parts 142 are provided, the two abutting parts 142 abut against the two convex parts respectively, the two convex parts rotate synchronously, and the driving surfaces m of the two convex parts can be adapted so that the combing piece 140 can still move when the two abutting parts 142 respectively abut against the corresponding driving surfaces m. Two protrusions may be respectively provided at both sides in the moving direction of the comb 140.

In some embodiments, referring to fig. 3, the driving structure 150 further includes an elastic member 152, and the elastic member 152 is connected between the housing 110 and the combing member 140 in a limiting manner and is deformable along a direction parallel to the axial direction Z of the rolling brush 120.

The elastic member 152 refers to a member that can be deformed in a deformation direction and returns to an original state when an external force is removed. The elastic member 152 may be a spring, a silicone member, a rubber member, etc., and is not particularly limited. The number of the elastic members 152 may be one or more.

The elastic member 152 may be fixedly connected, abutted, etc. with the housing 110 and the comb 140, and is not particularly limited as long as the elastic member 152 can be deformed by the movement of the comb 140.

In practice, the elastic member 152 is compressed or stretched when the comb 140 moves, and the movement of the comb 140 can be accelerated by the restoring force of the elastic member 152.

In one embodiment, referring to fig. 3 and 4, the driving structure 150 includes a cam 151 and an elastic member 152, the comb 140 abuts against a driving surface m of the cam 151, the cam 151 is located at one side of the comb 140 in the moving direction, and the elastic member 152 is located at the other side of the comb 140. When the cam 151 moves reversely after the combing member 140 is driven by the cam 151 to move in a direction parallel to the axial direction Z of the roller brush 120 to compress the elastic member 152, the roller brush 120 is pushed by the restoring force of the elastic member 152 to move toward the cam 151 and is held against the cam 151.

In some embodiments, referring to fig. 1 and 4, one of the housing 110 and the combing member 140 is provided with a limiting portion x1, and the other is provided with a limiting groove x2, the limiting groove x2 extends along a direction parallel to the axial direction Z of the rolling brush 120, and the limiting portion x1 penetrates through the limiting groove x2 and can move along the limiting groove x 2.

The limiting part x1 may be in the form of a limiting rod, a limiting shaft, a limiting pin, a limiting block, or the like, and is not limited. The limiting portion x1 penetrates through the limiting groove x2, and when the combing member 140 moves in the direction parallel to the axial direction Z of the rolling brush 120 relative to the housing 110, the limiting portion x1 moves in the limiting groove x 2.

At this time, the arrangement of the limiting portion x1 and the limiting groove x2 can guide the moving direction of the combing member 140, and improve the moving stability of the combing member 140.

In some embodiments, referring to fig. 5, in the radial direction of the rolling brush 120, the dimension L of the portion of the comb-teeth s extending into the bristles 121 is 2mm to 5mm. The length of the brush bristles 121 is usually within 2mm to 5mm, and the length of the comb teeth s and the dimension L may be equal to each other, may be smaller than the dimension L, may be larger than the dimension L, and is not particularly limited. Alternatively, the dimension L is 3mm, 4mm, etc.

When the size L of the portion of the comb teeth s extending into the bristles 121 is within the range of 2mm to 5mm, the comb teeth can be in sufficient contact with the bristles 121, so that the bristles 121 can be effectively spread.

In some embodiments, the floor brush 100 further comprises a scraping bar 130, the scraping bar 130 is disposed in the housing 110, and one end of the scraping bar 130 extends into the bristles 121, wherein the portion of the bristles 121 that contact the surface to be cleaned when the rolling brush 120 performs the cleaning operation is defined as the bristles to be cleaned, and the bristles to be cleaned contact the scraping bar 130 and then contact the combing members 140 during the rotation process until the bristles to be cleaned contact the surface to be cleaned next time.

The wiper strip 130 is a member having a certain hardness, which can wipe off dirt on the bristles 121. The wiper strip 130 may extend in parallel with the axial direction Z of the roller brush 120, or may extend in a direction intersecting the axial direction Z of the roller brush 120 at an acute angle. The scraping bar 130 may be only one, and the scraping bar 130 is disposed to extend in the axial direction Z of the roll brush 120. The scraping bar 130 may be a plurality of scraping bars 130, the plurality of scraping bars 130 are sequentially arranged in the axial direction Z of the rolling brush 120, and each scraping bar 130 is disposed to extend along the axial direction Z of the rolling brush 120. The wiper strip 130 may be a plastic or rubber. The surface of the wiper strip 130 on the side contacting the bristles 121 may be, but is not limited to, a flat surface, a curved surface, etc. The portion of the scraping bar 130 extending into the bristles 121 may be connected to the roller 122 to effectively scrape off the dirt on the bristles 121. The connecting manner of the scraper bar 130 and the housing 110 can be, but is not limited to, fastening connection, clamping connection, etc.

When the bristles to be cleaned rotate to the next contact with the surface to be cleaned, the bristles to be cleaned are firstly contacted with the scraping strip 130 to scrape off dirt on the bristles, the lodging degree of the bristles is deepened, and then the bristles are contacted with the combing piece 140, so that the bristles which are aggravated by the scraping strip 130 and are fallen on one side of the combing piece 140 can be combed and unfolded, and the cleaning effect is ensured. As will be understood in conjunction with fig. 5, on the rotation locus G of the brush staples 121, a position tangent to the surface to be cleaned is defined as a reference position C, and in the rotation direction of the roll brush 120, the bar 130 is located downstream of the reference position C and the comb 140 is located upstream of the reference position C. The rotation locus G is a circumference on which the outer edge of the brush 121 is located. The position where the rotation locus G is tangent to the surface to be cleaned refers to the position where the brush 121 contacts the surface to be cleaned, i.e. the brush 121 cleans the surface to be cleaned at the reference position C. In the rotating direction of the roller brush 120, the wiper strip 130 is located downstream of the reference position C, i.e., the bristles 121 are scraped off the dirt by the wiper strip 130 after cleaning the surface to be cleaned, and the comb members 140 are located upstream of the reference position C, i.e., the bristles to be cleaned are combed by the comb members 140 to spread before the next cleaning of the surface to be cleaned.

In actual operation, after cleaning the surface to be cleaned, part of the bristles 121 of the rolling brush 120 are scraped away from the rolling brush 120 under the action of the scraping strip 130, so that one side of the part of the bristles 121 is bent, and then the part of the bristles 121 are unfolded through the combing part 140 instead of being bent towards one side, so that the part of the bristles 121 can be effectively contacted with the surface to be cleaned when the part of the bristles 121 contacts the surface to be cleaned again.

At this time, the scraping strip 130 can scrape off dirt on the bristles 121, so that the dirt is prevented from being left on the bristles 121, the cleaning effect can be improved, and the bristles 121 can be kept in the unfolded state under the action of the comb-tooth part s, so that the bristles 121 can be effectively contacted with the cleaned surface.

In some embodiments, referring to fig. 1, the scraping bar 130 and the combing member 140 are located behind the rolling brush 120 in the advancing direction F of the floor brush 100. Understandably, when the bar 130 and the comb members 140 are positioned at the rear of the roll brush 120, the comb members 140 are positioned above the bar 130, the comb members 140 and the bar 130 are spaced relatively tightly, and the bristles 121 can be combed by the comb members 140 in a relatively short time after being acted on by the bar 130.

At this time, the structure of the floor brush 100 is more compact.

In other embodiments, the wiper strip 130 may be positioned at the rear of the roll brush 120 and the combing members 140 may be positioned at the front of the roll brush 120, as long as they can be combed by the combing members 140 when the bristles 121 clean the surface to be cleaned.

In some embodiments, referring to fig. 1, the scraping bar 130 extends along a direction parallel to the axial direction Z of the rolling brush 120. At this time, the wiper strip 130 may extend linearly to make effective contact with the roller brush 120, and the structure of the wiper strip 130 is simpler and easier to implement.

The scrubbing brush 100 that this application embodiment provided can scrape the dirt on the brush hair 121 through scraping strip 130, avoids dirty leaving over on brush hair 121, can improve clean effect, can make brush hair 121 keep under the state of expanding under the effect of broach portion s moreover, brush hair 121 can with by clean face carry out effective contact, further improved brush hair 121's clean effect.

In addition, based on the same inventive concept, a floor washing machine includes the floor brush 100 as in any of the above embodiments. The scrubber has all the above beneficial effects, which are not described herein.
