Description
TECHNICAL FIELD

The present disclosure relates to the technical field of cleaning devices, in particular to a floor brush structure.

BACKGROUND

For a traditional hard bristle rolling brush, there will be a large quantity of hairs tangled on the rolling brush during use, hard fiber bristles have a hard texture, once the hairs are tangled on the rolling brush, it is difficult to clean away, while a traditional soft bristle rolling brush has less prominent hair tangling problems compared to the hard bristle rolling brush. However, when cleaning a carpet, since soft bristles cannot be inserted into pile of the carpet, the carpet cleaning effect is not ideal compared to the hard bristles. Therefore, the traditional floor brushes cannot simultaneously solve hair tangling and ensure the cleaning effect, and the high efficiency of the floor brushes cannot be achieved.

It should be noted that the introduction of the background above is only for the purpose of providing a clear and complete explanation of the technical solution of the present disclosure and facilitating the understanding of those skilled in the art. The above technical solutions cannot be considered as well-known to those skilled in the art solely because they are elaborated in the background section of the present disclosure.

SUMMARY

In order to overcome the above shortcomings, an objective of the present disclosure is to provide a floor brush structure, through high-precision matching of structures and installation parameters of soft bristles, hard bristles and comb teeth, high efficiency of a floor brush is achieved, and thus the above technical problem is effectively solved.

In order to achieve the above objective, the technical solution adopted by the present disclosure is a floor brush structure, including:

    • a housing;
    • a rolling brush, including a rolling body, hard bristles and soft bristles, wherein
    • the rolling body is rotatably disposed in the housing, a plurality of hard bristles are disposed on an outer surface of the rolling body, a plurality of soft bristles are disposed on the outer surface of the rolling body, a height of the hard bristles is lower than a height of the soft bristles, and a height difference range of the hard bristles and the soft bristles is 0.2 mm to 5 mm; and
    • comb teeth, disposed in the housing and corresponding to the rolling brush, wherein when the rolling brush rotates, tooth tips of the comb teeth are able to be inserted into the hard bristles and the soft bristles to comb hairs tangled on the rolling brush, and a depth range of the tooth tips of heads of the comb teeth inserted into the hard bristles and the soft bristles is 0.1 mm to 5 mm.

The present disclosure has the beneficial effects: the soft bristles and the hard bristles are installed on the rolling body, when cleaning hairs on a floor, since the height of the soft bristles is larger than that of the hard bristles, the hairs may be cleaned away through the soft bristles, direct contact between the hairs and the hard bristles is reduced, at the same time, the hairs tangled on the rolling brush are combed by cooperating with the comb teeth, so that the technical problem that the floor brush is difficult to clean away due to hair tangling is effectively solved, the hard bristles on the rolling body may be inserted into pile of a carpet for cleaning it when the carpet is cleaned, and a function of the floor brush may not be affected. At the same time, in an installation process, parameters, such as the height difference between the soft bristles and the hard bristles and the depth of the comb teeth inserted into the soft bristles and the hard bristles are matched with an installation structure in high precision, so that optimal efficiency of the floor brush can be achieved during working.

When establishing installation parameters, a specific process is as follows:

1) the height difference between the hard bristles and the soft bristles needs to be controlled within a range of 0.2 mm to 5 mm, including 0.2 mm and 5 mm. Because when the heights of the hard bristles and the soft bristles are within this range, when it is used for cleaning the carpet, the hard bristles may be inserted into the pile of the carpet, which may easily remove dust from gaps of the carpet to be sucked by a vacuum cleaner, without affecting a cleaning effect of the rolling brush on the carpet, and when it is used for cleaning the floor, the height of the soft bristles is larger than that of the hard bristles, the soft bristles are in contact with the floor to clean it, the hairs on the floor are in contact with the soft bristles first, and a situation that the hairs are in direct contact with the hard bristles to be tangled on the rolling brush, which are difficult to clean away is avoided. In addition, when cleaning the floor, a situation that the gloss of the floor is damaged by direct contact between the hard bristles and the floor can further be effectively prevented. If the height difference between the hard bristles and the soft bristles is smaller than 0.2 mm, the hard bristles and the soft bristles are almost of the same height, in this way, when the brush is used for cleaning the floor, the hard bristles are likely to be in direct contact with the hairs, causing the hairs to be tangled on the rolling brush, and moreover, the hard bristles may further be in contact with the floor, causing damage to the floor. If the height difference between the hard bristles and the soft bristles is greater than 5 mm, the height difference between the hard bristles and the soft bristles is too large, in this way, when the brush is used for cleaning the carpet, the hard bristles cannot be inserted into the pile of the carpet, thereby affecting the cleaning effect on the carpet.

2) During installation, it is necessary to ensure that the depth of tooth tips of the heads of the comb teeth inserted into the hard bristles and the soft bristles is within a range of 0.1 mm to 5 mm, because only the depth of the tooth tips inserted into the bristles is controlled within this range, the tooth tips of the comb teeth can effectively achieve the goal of not affecting the rotation of the rolling brush but also effectively combing the hairs tangled on the rolling brush. If the insertion depth is smaller than 0.1 mm, the hairs tangled on the rolling brush cannot be effectively cleaned away by the tooth tips of the comb teeth. If the insertion depth is greater than 5 mm, the tooth tips of the comb teeth may affect the normal rotation of the rolling brush due to excessive insertion.

Further, a plurality of tooth tips of the comb teeth are arranged in an axial direction of the rolling body, a spacing range between two adjacent tooth tips is 2 mm to 6 mm, and a tooth tip angle range of the heads of the comb teeth is 8° to 105°. When an angle of the tooth tips of the heads of the comb teeth is within the range of 8° to 105°, the tooth tips of the comb teeth are inserted into the bristles, so as to effectively comb the tangled hairs. If the angle of the tooth tips of the comb teeth is smaller than 8°, the strength at the tooth tips is too low, which is easy to break, and it is also difficult to form during manufacturing. If the angle of the tooth tips of the comb teeth is greater than 105°, the tooth tips of the comb teeth are too large, and the tangled hairs cannot be effectively cleaned away.

Further, the plurality of hard bristles are arranged on a surface of one substrate to form a plurality of hard bristle strips, the plurality of soft bristles are arranged on a surface of one substrate to form a plurality of soft bristle strips, and the hard bristle strips and the soft bristle strips are divided into a plurality of groups of one hard bristle strip and one soft bristle strip to be disposed on a surface of the rolling body. When the hard bristles and the soft bristles are installed on the rolling body, all the hard bristles may be woven onto one substrate to form a complete hard bristle strip, then all the soft bristles are woven on one substrate to form a complete soft bristle strip, and then the hard bristle strips and the soft bristle strips are installed on the rolling body in pairs.

Further, a plurality of first grooves are formed in the surface of the rolling body, each first groove is a combined groove with two grooves as one group, one hard bristle strip is installed in one groove, and one soft bristle strip is installed in the other groove. When the hard bristles and the soft bristles are installed on the rolling body, all the hard bristles may be woven on one substrate to form a complete hard bristle strip, then all the soft bristles are woven on one substrate to form a complete soft bristle strip, and then the hard bristle strips and the soft bristle strips are installed on the rolling body in pairs. When the hard bristle strips and the soft bristle strips are installed on the rolling body in pairs, grooves may be formed in the rolling body, the grooves may be in a V-shape, an inverted V-shape, a spiral shape and the like, and the hard bristle strips and the soft bristle strips may be inserted into the grooves through oblique or direct insertion to complete the installation. At the same time, the grooves may also be omitted, and the hard bristle strips and the soft bristle strips directly adhere to the rolling body with glue.

Further, a spacing range between the two grooves in the combined groove is 1 mm to 15 mm. When the hard bristle strips and the soft bristle strips are used in pairs, a spacing between the two grooves cannot exceed 15 mm, if it exceeds 15 mm, when the rolling brush is used, the hard bristle strips and the soft bristle strips cannot be matched with each other, so the spacing range of the grooves for installing the hard bristle strips and the soft bristle strips set to be 1 mm to 15 mm.

Further, the plurality of soft bristles and the plurality of hard bristles are disposed on a surface of one substrate at the same time to form a plurality of soft and hard bristle strips, and the soft and hard bristle strips are disposed on the surface of the rolling body. The soft bristles and the hard bristles are woven with one substrate to form a complete soft and hard bristle strip, and then the soft and hard bristle strips are installed on the rolling brush.

Further, the plurality of hard bristles are arranged on the substrate to form a hard bristle layer, the plurality of soft bristles are arranged on the surface of the substrate to form a soft bristle layer, and the hard bristle layer and the soft bristle layer are disposed in parallel. On the soft and hard bristle strips, all the hard bristles are arranged to form a hard bristle layer, all the soft bristles are arranged to form a soft bristle layer, and the soft bristle layer and the hard bristle layer are arranged in parallel.

Further, a spacing range between the hard bristle layer and the soft bristle layer is 0 mm to 15 mm. When the hard bristle layer and the soft bristle layer are parallelly formed into a brush layer and disposed on the surface of the substrate, there may not or may be a spacing between the hard bristle layer and the soft bristle layer, but the spacing between the two cannot exceed 15 mm, and if it exceeds 15 mm, when the rolling brush is used, the hard bristles and soft bristles on the bristle strips cannot be matched with each other.

Further, a plurality of second grooves are formed in the surface of the rolling body, and one soft and hard bristle strip is installed in one second groove. When the soft and hard bristle strips are installed on the rolling body, grooves may be formed in the rolling body, the grooves may be in a V-shape, an inverted V-shape, a spiral shape and the like, and the soft and hard bristle strips may be inserted into the grooves through oblique or direct insertion to complete the installation. At the same time, the grooves may also be omitted, and the soft and hard bristle strips directly adhere to the rolling body with glue.

This embodiment provides a floor brush structure, as shown in FIGS. 1-2, the floor brush structure includes a housing 1; and further includes a rolling brush 2, the rolling brush 2 includes a rolling body 2.1, hard bristles 2.2 and soft bristles 2.3, wherein the rolling body 2.1 is rotatably disposed in the housing 1, a plurality of hard bristles 2.2 are arranged around an outer surface of the rolling body 2.1, a plurality of soft bristles 2.3 are arranged on an outer surface of the rolling body 2.1, and a height of the hard bristles 2.2 is lower than a height of the soft bristles 2.3; and

the floor brush structure further includes comb teeth 3, disposed in the housing 1 and corresponding to the rolling brush 2. When the rolling brush 2 rotates, tooth tips of the comb teeth 3 are able to be inserted into the hard bristles 2.2 and the soft bristles 2.3 to comb hairs tangled on the rolling brush 2.

In the above embodiment, a height difference range of the hard bristles 2.2 and the soft bristles 2.3 is 0.2 mm to 5 mm; and a height difference between the hard bristles 2.2 and the soft bristles 2.3 needs to be controlled within the range of 0.2 mm to 5 mm, including 0.2 mm and 5 mm.

Because when the heights of the hard bristles 2.2 and the soft bristles 2.3 are within this range, when the floor brush structure is used for cleaning a carpet, the hard bristles 2.2 may be inserted into pile of the carpet, which may easily remove dust from gaps of the carpet to be sucked by a vacuum cleaner, without affecting a cleaning effect of the rolling brush 2 on the carpet, and when it is used for cleaning a floor, the height of the soft bristles 2.3 is larger than that of the hard bristles 2.2, the soft bristles 2.3 are in contact with the floor to clean it, the hairs on the floor are in contact with the soft bristles 2.3 first, and a situation that the hairs are in direct contact with the hard bristles 2.2 to be tangled on the rolling brush 2, which are difficult to clean away is avoided. In addition, when cleaning the floor, a situation that the gloss of the floor is damaged by direct contact between the hard bristles 2.2 and the floor can further be effectively prevented. If the height difference between the hard bristles 2.2 and the soft bristles 2.3 is smaller than 0.2 mm, the hard bristles 2.2 and the soft bristles 2.3 are almost of the same height, in this way, when the brush is used for cleaning the floor, the hard bristles 2.2 are likely to be in direct contact with the hairs, causing the hairs to be tangled on the rolling brush 2, and moreover, the hard bristles 2.2 may further be in contact with the floor, causing damage to the floor. If the height difference between the hard bristles 2.2 and the soft bristles 2.3 is greater than 5 mm, the height difference between the hard bristles 2.2 and the soft bristles 2.3 is too large, in this way, when the brush is used for cleaning the carpet, the hard bristles 2.2 cannot be inserted into the pile of the carpet, thereby affecting the cleaning effect on the carpet.
