The terms "first," "second," and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features. The meaning of "a plurality of" is two or more, unless specifically defined otherwise.

In order to explain the technical scheme of the application, the following is a detailed description with reference to the specific drawings and embodiments.

Referring first to fig. 4 and 5, the present embodiment first provides a rolling brush assembly 100 (referring to fig. 2 and 3), which is used in a floor sweeper 200, and specifically is disposed on a side of the floor sweeper 200 (the side is defined as a bottom based on a use state thereof) for sweeping the floor.

Specifically, referring to fig. 4 and 5, in the present embodiment, the roller brush assembly 100 includes a roller brush core 1, and a plurality of rows of bristles 2 and a plurality of barrier ribs 31 disposed on the roller brush core 1. The roller brush core 1 is in a column shape and is used for rotating around the axial direction of the roller brush core under the driving of a driving component (not shown) of the sweeper 200. The bristles 2 and the barrier ribs 31 extend from one axial end to the other axial end of the rolling brush core 1, the bristles 2 and the barrier ribs 31 are alternately arranged along the circumferential direction of the rolling brush core 1, a row of bristles 2 is arranged between the two barrier ribs 31, and a barrier rib 31 is arranged between the two rows of bristles 2. When the roll brush core 1 rotates, the brush hair 2 and the barrier rib 31 rotate synchronously, and the brush hair 2 and the barrier rib 31 contact the ground (or garbage and foreign matters on the ground) alternately in turn, so that the ground is cleaned.

In this embodiment, as shown in fig. 4, each barrier 31 has a row of bristles 2 on two circumferential sides, and the distances between the barrier 31 and two rows of bristles 2 adjacent thereto are unequal. That is, the barrier 31 is closer to the bristles 2 on one side thereof.

Because the multiple rows of bristles 2 are arranged along the circumferential direction of the rolling brush core 1, when the hairs are wound on the two adjacent rows of bristles 2, the barrier strips 31 have more obvious supporting effect on the hairs, and the hairs cannot sink into the bristles 2, so that the hairs are convenient for a user to clean; in addition, a larger space is reserved between the barrier strip 31 and the brush hair 2 on the other side, and when a user needs to cut hair by using tools such as a knife, the barrier strip 31 can not block the movement of the tools, so that the hair can be cut conveniently; in addition, the hairs are supported far from the surface of the rolling brush core 1, which is also beneficial for cutting the hairs, so that the cleaning difficulty is further reduced.

Therefore, in the rolling brush assembly 100 provided by the embodiment of the application, the distance between the barrier strips 31 and the two rows of brush hairs 2 adjacent to the barrier strips is unequal on the rolling brush core 1, so that a user can clean the hair in a more convenient and labor-saving manner, and the user experience is obviously improved.

When the roller brush assembly 100 rotates in the sweeper 200, it has a specific rotation direction, and based on the rotation direction, a front and a rear can be defined. As will be understood with reference to fig. 6, assuming that the rotation direction of the rolling brush assembly 100 is clockwise, the position a is located in front of the position B shown in fig. 6, and the position a contacts the ground first and the position B contacts the ground later during one rotation of the rolling brush assembly 100.

Based on the above, in the embodiment of the present application, as shown in fig. 6, in the rotation direction of the roll brush core 1, the distance from the barrier 31 to the front row of bristles 2 is D1, and the distance from the barrier 31 to the rear row of bristles 2 is D2, then D1 and D2 are not equal.

Here, the definition criteria of D1 and D2 are consistent, that is, the calculation needs to be performed at the same radial length from the central axis of the roll brush core 1, which may refer to a circumferential distance (arc length) or a linear distance. For example, D1 and D2 may each be calculated based on the root of the bar 31 and the bristle 2, or may be calculated based on the top of the relatively shorter one of the bar 31 and the bristle 2.

It will be appreciated that in measuring or calculating D1, D2, the calculation should also be performed at the same position along the axial direction of the roll brush core 1, as shown in fig. 6.

For ease of understanding or calculation, in one embodiment, as shown in FIG. 7, D1 and D2 are arc lengths calculated based on the bars 31 and the roots of the bristles 2; alternatively, as shown in fig. 6, in another embodiment, D1 and D2 are the lengths of straight lines calculated based on the roots of the bristles 2 and the bars 31.

In one embodiment, referring to FIG. 6 in combination, D1 > D2. That is, the barrier rib 31 is closer to the row of bristles 2 located at the rear thereof in the rotational direction of the roll brush assembly 100. The purpose of this design is that when the rolling brush assembly 100 works, the trash and foreign matters on the ground will first touch the barrier rib 31 and then touch the brush hair 2, so that the barrier rib 31 will block a part of trash and foreign matters even larger than the brush hair 2, and the barrier rib 31 is relatively easier to clean compared with the brush hair 2, therefore, the difficulty of cleaning the rolling brush assembly 100 by the user can be reduced, and the user experience is further improved.

For the rolling brush assembly 100 applied to the floor sweeping machine 200 with different models or sizes, the diameter of the rolling brush core 1, the number (row number) of the bristles 2 and the like may be different, and a specific design is required to achieve a better sweeping effect.

In one embodiment, the rolling brush assembly 100 is used in a home automatic sweeper 200 (sweeping robot), where D1 is 2mm to 5mm and D1 is the arc length calculated based on the bars 31 and the roots of the bristles 2. More specifically, the roller brush assembly 100 includes three bars 31 and three rows of bristles 2. For the rolling brush assembly 100 of the hand-held sweeper or other sweeper used in commercial environment, the number of bristles 2 and the values of D1 and D2 may be designed correspondingly, and will not be described in detail herein.

Referring to fig. 4 and 6, in one embodiment, the length (radial height) of the bristles 2 is greater than the length (radial height) of the bars 31. The purpose of this design is that every row of brush hair 2 comprises a plurality of brush hair silk that the diameter is very little, and the brush hair silk is out of shape easily and each brush hair silk influence each other when warping is littleer, no matter the blend stop 31 is flexible blend stop or inflexible blend stop, and brush hair 2 is more comprehensive to the cleaning effect on ground, can guarantee the normal play of effect of brush hair 2 at the in-process of sweeping the floor.

As shown in fig. 6, in one embodiment, the difference H in radial height (distance between tips) of the bristles 2 and the barrier rib 31 is 3mm to 6mm. It is understood that the difference between the radial heights of the bristles 2 and the bars 31 may be designed to have other values in the roller brush assembly 100 of the sweeper 200 of other types or sizes by way of example only.

Generally, when the rolling brush assembly 100 is operated, the interference length between the top of the brush hair 2 and the ground can be designed according to the specific type of the sweeper 200 and the characteristics of the brush hair 2, for example, about 1mm, so that a gap of 2 mm-5 mm can be formed between the top of the barrier strip 31 and the ground, and the gap size can be adapted to the current household environment, and is not obviously smaller than the size of the garbage and foreign matters in the household environment, thereby ensuring the sweeping effect. In other cases, the gap between the top of the barrier rib 31 and the ground may have other values, and will not be described in detail herein.

Wherein in an alternative embodiment barrier rib 31 is a flexible barrier rib. Thus, when the barrier rib 31 contacts a large-sized foreign matter on the ground during rotation, it is appropriately deformed to prevent the ground from being scratched by pressing the foreign matter between it and the ground.

The barrier 31 is more prone to a continuous unitary structure than if the bristles 2 were made up of a significant number of bristle filaments. Of course, it will be appreciated that, according to actual needs, the barrier 31 may be provided with a plurality of notches 310 for avoiding the structure of filtering large-sized foreign matters, such as iron wires disposed at the bottom of the housing 91 of the sweeper 200.

In one embodiment, referring to fig. 4 and 5, the flexible barrier rib 31 is formed by the soft rubber cylinder 3 and is integrally fixed with the rolling brush core 1. Specifically, as shown in fig. 5, the soft rubber cylinder 3 includes a cylinder 32 and the barrier rib 31, where the cylinder 32 is a hollow cylinder, and is coated on the periphery of the rolling brush core 1, and the barrier rib 31 and the cylinder 32 are integrally formed. The purpose of this design is that by means of the cylinder 32, the barrier 31 can be fixed with the roll brush core 1 in a simpler manner, and the connection between the barrier 31 and the roll brush core 1 is more stable.

Specifically, the soft rubber cylinder 3 may be flexible plastic, rubber, silica gel or the like, and is formed into an integral structure with the rolling brush core 1 by integral injection molding. The roll brush core 1 is a rigid piece, which may be a hard plastic piece or a metal piece with a relatively light weight, etc.

In one embodiment, referring to fig. 5, a plurality of holes 10 are formed in both the barrel 32 and the rolling brush core 1, and the bristles 2 are fixed in the holes 10 of the rolling brush core 1 after passing through the barrel 32 via the holes 10 of the barrel 32. In specific production, the barrel 32 without the implantation holes 10 can be formed on the rolling brush core 1 through integral injection molding, then the barrel 32 and the rolling brush core 1 are perforated, and finally, the implantation holes 10 on the rolling brush core 1 are implanted with bristles to form a plurality of rows of bristles 2.

Referring to fig. 4 and 5, each row of bristles 2 and each barrier rib 31 extends continuously from one axial end of the roll brush core 1 to the other axial end thereof. However, it is understood that the extending direction of the bristles 2 and the bars 31 may be inclined with respect to the axial direction instead of the axial direction.

For example, the bristles 2 and the barrier ribs 31 are all spirally arranged from one end to the other end in the axial direction of the roll brush core 1; alternatively, as shown in fig. 4 and 5, the bristles 2 and the barrier ribs 31 are spirally arranged from both ends to the middle. The purpose of this design is that when the rolling brush assembly 100 rolls on the ground, at any moment, a small part of the bristles 2 and the barrier ribs 31 are deformed under the action of the ground, and the deformed bristles 2 and barrier ribs 31 generate a reaction force on the rolling brush core 1, so that the rolling brush core 1 vibrates up and down, and therefore, the reaction force applied by the rolling brush core 1 can be dispersed in a rotation process of one circle more evenly by the spirally designed bristles 2 and barrier ribs 31, and thus, the overall rotation of the rolling brush assembly 100 is more stable.

Referring to fig. 5, in one embodiment, the rolling brush assembly 100 further includes a connecting shaft 4 disposed at one axial end of the rolling brush core 1, a bearing 5 and a bearing seat 6, wherein the connecting shaft 4 is used for connecting the rolling brush core 1 and the driving assembly, the bearing 5 is sleeved on the connecting shaft 4 and is installed in the bearing seat 6, and the bearing seat 6 is fixedly installed on the machine body 91 of the sweeper 200. In this way, it is possible to realize that the rolling brush assembly 100 is mounted on the body 91 and can be rotated by the driving assembly. The end of the roll brush core 1 to which the connecting shaft 4 is attached is a driving end, and the other end is a driven end, and the driven end may be rotatably attached to the body 91 via another bearing (not shown) or the like.

Referring to fig. 2 and 3, and referring to fig. 4 to 6, the embodiment of the application further provides a sweeper 200, which includes a main body 91 and the rolling brush assembly 100 provided on the main body 91. The features of the roller brush assembly 100 are not described in detail herein.

The sweeper 200 according to the embodiment of the present application includes the rolling brush assembly 100 according to the above embodiments, and thus has the corresponding advantages of the rolling brush assembly 100 according to the above embodiments.

As previously described, the sweeper 200 is referred to herein as a sweeping robot (including a sweeping and mopping robot), a hand-held sweeper, a commercial sweeper, or the like.

Specifically, in one embodiment, the sweeper 200 is a sweeping robot, as shown in fig. 3, and further includes a driving wheel assembly 93, an edge brush assembly 92, a universal wheel 94, and the like, which are disposed at the bottom of the machine body 91. The body 91 may include a body main body 911 and a body base 912 positioned thereunder. The sweeper 200 further includes a dust box (not shown) provided in the main body 91, the dust box being communicated with the dust suction port, and the dust and foreign matter and the like cleaned by the roller brush assembly 100 being introduced into the dust box through the dust suction port.

Further, in an alternative embodiment, the sweeper 200 may include a water tank (not shown) disposed within the body 91, a wiper assembly 95 disposed at the bottom of the body 91, etc., as shown in fig. 3, so that the sweeper 200 may be provided with an automatic mopping function.

In an alternative embodiment, the sweeper 200 may include a front striker plate 96 disposed on the front side of the fuselage 91 (determined based on the direction of movement), a radar 97 disposed on the upper side of the fuselage 91, and the like, as shown in fig. 2. The front collision plate 96 is used to collide directly with an obstacle during movement of the body 91 and to buffer the collision, and the radar 97 is used to provide map information and the like in a clean environment for the sweeper 200.

The foregoing description of the preferred embodiments of the application is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the application.
