DETAILED DESCRIPTION OF THE INVENTION

[0038] Preferred embodiments of the present disclosure are described in detail below with reference to the accompanying drawings, so that advantages and features of the present disclosure are easier to understand by those skilled in the art, and thus the protection scope of the present disclosure is defined more clearly.

Embodiment 1

[0039] As shown in FIG. 1 and FIG. 2, the present embodiment is a cleaning strip 1, and the cleaning strip 1 is a flexible cleaning strip 1 made of a flexible material. Flexible here means that the cleaning strip 1 has certain hardness but still has certain deformability and elastic recovery force, for example, at least one of plastics, silica gel or soft rubber may be used. For example, there may be polyurethane (PU) elastomer, thermoplastic elastomer (TPE), polyvinyl chloride (PVC), etc.

[0040] The cleaning strip 1 of the present embodiment includes a mounting region 12 and at least one cleaning protrusion 11 connected with the mounting region 12, a notch 13 is formed between any two cleaning protrusions 11, one end of the notch 13 away from the mounting region 12 has a width greater than 0 mm, and one end of the notch 13 close to the mounting region 12 has a width greater than or equal to 0 mm. Namely, no gap may be arranged at a root (one end close to the mounting region 12) of each cleaning protrusion 11, and when the cleaning strip 1 is arranged on a roller brush body, the notches are formed on an outer surface of a brush body portion 22. Namely, each cleaning protrusion 11 has a relatively large length in a width direction of the cleaning strip 1, thereby guaranteeing that when the cleaning strip 1 is mounted on the roller brush body, a length of the cleaning strip 1 extending into fur of a carpet is large and then effectively cleaning hair in the carpet. It is noted that each cleaning protrusion 11 in the solution of the present embodiment has a relatively large height above a surface of the roller brush body instead of only a sawtooth shape arranged in a limited width of an outer edge of the cleaning strip 1. Thus, the cleaning protrusions 11 of the present application can fully extend into the carpet to effectively clear the hair in the carpet.

[0041] Therefore, without additionally arranging other cleaning elements, an effect of cleaning a floor and the carpet may be achieved only by using a roller brush provided with the cleaning strip 1 of the present application. During carpet cleaning by using the roller brush provided with the cleaning strip 1 of the present embodiment, the cleaning protrusions 11 can extend into the carpet to clear the hair and the like in the carpet. The notch 13 is formed between any two cleaning protrusions 11 of the cleaning strip 1 of the present application, and the cleaning protrusions 11 are flexible, so the hair is neither prone to being clamped by the adjacent cleaning protrusions 11, nor prone to being intertangled on the cleaning strip 1.

[0042] During carpet cleaning by using a floor brush provided with the cleaning strip 1 of the present embodiment, the cleaning protrusions 11 have certain elasticity, so the cleaning protrusions can flap and dig up in the carpet. The cleaning strip 1 can have better adhesive force with the fur of the carpet due to the certain elasticity of the cleaning strip 1, so friction force between the floor brush and the carpet is greater, the cleaning strip 1 can cause the fur of the carpet to bring stronger tractive force on the floor brush so as to drive the floor brush to automatically move forwards, and dust in gaps of even a long-fur carpet can be easily flapped and dug out to be sucked into a dust cup by a vacuum cleaner without manual push basically. The notches 13 arranged between the respective cleaning protrusions 11 can guarantee that the cleaning strip 1 does not completely press down the fur on a surface of the carpet, and thus an unfavorable influence of collapse of an appearance of the carpet after cleaning is completed is not caused.

[0043] In some implementations, the cleaning strip 1 has a shore hardness A ranging from 30 degrees to 85 degrees. If the hardness of the cleaning strip 1 is too low, there is no effect of digging up the hair and the like. If the hardness of the cleaning strip 1 is too high, on the one hand, the carpet is prone to being damaged, and on the other hand, if gaps between the adjacent cleaning protrusions 11 are too small, the hair is still prone to being intertangled on a surface of the cleaning strip 1. Thus, in the present application, by controlling the hardness of the cleaning strip 1 to be shore hardness A ranging from 30 degrees to 85 degrees, the cleaning strip 1 has both appropriate flexibility and strength. In addition, the cleaning strip 1 has certain flexibility and elasticity, so the cleaning strip can adapt to an uneven ground surface and effectively clear the hair and the like on different surfaces such as the floor and the carpet and cannot cause the hair to be clamped or intertangled by the cleaning strip 1.

[0044] In some implementations, an external diameter of each cleaning protrusion 11 gradually decreases towards one end away from the mounting region 12. For example, each cleaning protrusion 11 may be in at least one shape of tooth shape, taper shape, or truncated taper shape (such as a cone shape or pyramid shape).

[0045] In some implementations, the cleaning strip 1 is in a platy shape and is obtained by forming a notch 13 through punching or cutting an edge of a platy strip, each cleaning protrusion 11 is a region at an edge of the cleaning strip 1 without punching or cutting, and as shown in FIG. 1 and FIG. 2, each cleaning protrusion 11 is a plurality of tooth-shaped structures arranged at an edge of the strap. Thus, the cleaning strip 1 of the present application may be obtained only by using the strap and the like widely applied in the industry of vacuum cleaners at present and simply punching or cutting an edge of the strap to form some V-shaped grooves or arc-shaped grooves. Therefore, the cleaning strip 1 has extremely low machining cost and simple machining process. Arc-shaped groove punched here means that a left side wall and a right side wall of the groove are arc-shaped (as shown in FIG. 3). A bottom of the punched groove may be in a V shape or an arc chamfer shape. A case where the bottom of the groove is in a V shape is a case where spacing between ends of the respective cleaning protrusions 11 close to the mounting region 12 is 0.

[0046] The present application breaks the routing of the industry, the notches 13 are formed in the strap which cannot play a role in extending into the carpet to directly clear the hair, so as to form the plurality of cleaning protrusions 11, so the cleaning protrusions 11 can directly extend into the carpet for cleaning, namely, the structure of the cleaning protrusions 11 of the strap is used for directly playing a role in cleaning.

[0047] In other possible implementations, each cleaning protrusion 11 is columnar (for example, may be cylindrical, cuboid, cube, prismatic shape and the like), and one end of each notch 13 close to the mounting region 12 has a width greater than 0 mm. Each cleaning protrusion 11 is columnar, so a width of one end of the notch 13 close to the mounting region 12 needs to be set as greater than 0 mm, and thus it may be guaranteed that there are enough gaps between the respective cleaning protrusions 11.

[0048] In some implementations, the spacing between ends of any two cleaning protrusions 11 close to the mounting region 12 does not exceed 30 mm. Otherwise, the too large spacing may result in that the surface of the floor or the carpet cannot be effectively cleaned.

[0049] In some implementations, each cleaning protrusion 11 has a width ranging from 1 mm to 20 mm. Width of the cleaning protrusion 11 here refers to a length (in a case where the cleaning protrusion 11 is in a tooth shape) or an external diameter (in a case where the cleaning protrusion 11 is in a taper shape, a truncated taper shape or a columnar shape) of the cleaning protrusion 11 in a length direction of the cleaning strip 1. The width of the cleaning protrusion 11 may be adjusted according to a length of the roller brush. For example, in a small roller brush, as the length of the roller brush is usually in a range from 10 cm to 30 cm, in this case, the width of the cleaning protrusion 11 may be set only as 1 mm, 3 mm, 5 mm or the like. In a large industrial vacuum cleaner, as the length of the roller brush may reach 2 m to 3 m, in this case, the width of the cleaning protrusion 11 may also be set as 20 mm. A proportion for which a set width of each cleaning protrusion 11 accounts in a length direction of the roller brush body is extremely low, for example, it may be 0.05%, 0.1%, 0.2%, 0.5%, 1% or the like. This is for forming a structure of the plurality of cleaning protrusions 11 capable of extending into the carpet for cleaning in the cleaning strip 1.

Embodiment 2

[0050] The present embodiment is a roller brush body 2. The roller brush body 2 may be a cleaning brush used for a floor brush of a vacuum cleaner or a cleaning brush of a sweeper or a cleaning brush of a sweeping robot. As shown in FIG. 4 and FIG. 5, the roller brush body includes a body portion 21, at least one mounting groove 211 for arranging a cleaning strip 1 is formed in an outer surface of the body portion 21, and a mounting region of the cleaning strip 1 may be clamped into the mounting groove 211. A notch 13 is further formed between any two adjacent cleaning protrusions 11 of the cleaning strip 1, one end of the notch 13 away from a brush body portion 22 has a width greater than 0 mm, and one end of the notch 13 close to the brush body portion 22 has a width greater than or equal to 0 mm. The roller brush body 2 of the present embodiment breaks the limit of an existing roller brush body 2, and the cleaning protrusions 11 can not only clear dirt on a surface of a floor, but also extend into a carpet to effectively dig up and clear hair and the like, so an effect of cleaning the hard floor and the carpet may be achieved only by using one cleaning element of the roller brush body 2 of the present embodiment.

[0051] An arrangement mode of the respective cleaning protrusions 11 arranged on the outer surface of the roller brush body 2 is at least one of the following modes: arrangement in an axial direction of the roller brush body 2 (FIG. 5), spiral arrangement along a surface of the roller brush body 2 (FIG. 4), staggered arrangement on the surface of the roller brush body 2 (FIG. 10), and V-shaped arrangement along the surface of the roller brush body 2. The respective cleaning protrusions 11 may be continuously or discontinuously arranged (FIG. 10). The mounting groove 211 may be of a groove structure in various shapes such as a skewed groove, a straight groove, a V-shaped groove, a groove in a shape of Chinese character ren and a spiral groove.

[0052] There may be at least one row of cleaning protrusions 11 arranged on the surface of the roller brush body 2, two adjacent rows of cleaning protrusions 11 may be staggered as required, for example, the latter row of cleaning protrusions 11 just face gaps between the former row of adjacent cleaning protrusions 11, and thus the respective rows of cleaning protrusions 11 may play a better role in cooperating and achieve a better effect of cleaning dirt.

[0053] In some possible implementations, as shown in FIG. 6, there may be a plurality of mounting grooves 211 formed in the outer surface of the body portion 21, and three mounting grooves 211 constitute one group. One group means that spacing between mounting grooves 211 in each group is smaller than a distance between two adjacent groups of mounting grooves 211. According to an order in which a roller brush makes contact with the ground surface when rotating in sequence, cleaning elements arranged in each group of mounting grooves 211 are sequentially a cleaning strip 1, a strap 4 and a brush 5. Thus, the surface of the carpet, inside of the carpet and a surface of the hard floor can be effectively cleaned.

[0054] In some possible implementations, the body portion 21 and the brush body portion 22 are two different components. As shown in FIG. 7 to FIG. 10, the brush body portion 22 may include one hollow columnar brush body main body 221, and the respective cleaning protrusions 11 are integrally formed on an outer surface of the brush body main body 221. Correspondingly, the roller brush body 2 has one body portion 21 located on an inner side of the brush body main body 221, so the brush body portion 22 with the plurality of cleaning protrusions 11 may be machined first through extrusion molding, blow molding, foam molding, reverse mould molding and other processes. Then, the brush body portion 22 is connected to an outer surface of the body portion 21 of the roller brush body 2 in a sleeving mode. In other possible implementations, the brush body portion 22 may also be directly arranged on the outer surface of the body portion 21 through injection molding or rubber coating.

[0055] In some implementations, the body portion 21 and the brush body portion 22 may also be an integrally formed component. For example, various soft materials such as plastics, silica gel or soft rubber with a shore hardness A ranging from 30 degrees to 85 degrees may be adopted, a comb shape, a sawtooth shape and a columnar shape may be directly formed on the outer surface of the brush body portion through injection molding, or an integrated structure of the roller brush body with the plurality of cleaning protrusions 11 may be directly produced through extrusion molding, blow molding, foam molding, reverse mould molding and other processes.
