Fig. 3 is an enlarged view of a separation line 30 near the right side of fig. 2, as shown in fig. 3, the first bristle bundle 20A includes a plurality of first bristles 21A, the second bristle bundle 20B includes a plurality of second bristles 21B, wherein an area of an end surface 211A of a top end of the first bristles 21A is smaller than an area of an end surface 211B of a top end of the second bristles 21B, and the first bristles 21A are easier to deform than the second bristles, specifically, as shown in fig. 4, the first bristles 21A and the second bristles 21B are made of different materials, and a hardness of a material used for the first bristles 21A is smaller than a hardness of a material used for the second bristles 21B, that is, the first bristles 21A are softer and easier to deform than the second bristles 21B.

In the first preferred embodiment of the present utility model, the first bristles 21A are bristles made of polybutylene terephthalate (Polybutylene terephthalate, PBT), and the second bristles 21B are bristles made of Polyamide (PA) fiber, that is, nylon (Nylon), so that the first bristles 21A with relatively soft material and small area of the end surface 211A can extend into the teeth to clean the gaps while avoiding damaging the gums, and the second bristles 21B with relatively hard material and large area of the end surface 211B can effectively abrade the tooth surfaces of the teeth.

In addition, in fig. 1 and 2, the first bristle bundle 20A and the second bristle bundle 20B are drawn in a block form in order to avoid excessive dots and lines of the drawing, to influence the reading of the drawing and the symbols, and to clearly see the boundary 30 between the first bristle bundle 20A and the second bristle bundle 20B, which are shown in a schematic manner, not to show the actual structures of the first bristle bundle 20A and the second bristle bundle 20B.

Referring to fig. 5 and 6, a part of the process of manufacturing the brush sheet 80 according to the first preferred embodiment of the present utility model is shown in fig. 5, wherein a bristle part 20 including the first bristle bundle 20A and the second bristle bundle 20B is inserted into the corresponding mounting hole 11 from the upper side to the lower side in fig. 5 (the direction shown by the arrow in fig. 5), and a small section of the bristle part 20 is left protruding above the mounting hole 11, and in this way, a plurality of bristle parts 20 are inserted into the plurality of mounting holes 11 of the body 10, respectively, and then a connecting step is performed.

As shown in fig. 5, the body 10 is provided with a plurality of protruding columns 13 protruding around the mounting hole 11, and in the connecting step, the parts of the bristle parts 20 protruding above the mounting hole 11 in fig. 5 and the protruding columns 13 are heated and melted to be connected, as shown in fig. 6, and finally a hot-melt combined body 40 is formed, as shown in fig. 7, whereby the bristle parts 20 can be respectively and fixedly mounted in the mounting holes 11 of the body 10 without easily falling off; the heat fusion bonding body 40 can be then covered by injection molding or other methods to increase the aesthetic appearance, thereby completing the manufacture of the brush sheet 80.

As shown in fig. 8, the second preferred embodiment of the present utility model provides a toothbrush comprising the brush piece 80 of the first preferred embodiment of the present utility model and a handle 90, wherein the handle 90 is connected to the body 10 of the brush piece 80, and the handle 90 is used for holding the toothbrush by a user, in the second preferred embodiment of the present utility model, the handle 90 and the body 10 of the brush piece 80 are injection molded together, while in other embodiments, the handle 90 and the body 10 of the brush piece 80 may be separately molded and connected through a subsequent assembling operation, or the handle 90 may be additionally formed with a non-slip structure by Two-shot molding (Two-shot Injection Molding), and the actual connection manner and additional arrangement of the handle 90 are not limited by the second preferred embodiment of the present utility model.

When the toothbrush comprising the brush piece 80 is used for brushing teeth, in the process of cleaning teeth by one of the brush hair parts 20, specifically, when the first brush hair bundles 20A with softer materials and smaller end surface area in the brush hair parts 20 extend into the gaps between teeth for cleaning, the second brush hair bundles 20B with harder materials and larger end surface area in the brush hair parts 20 can be used for rubbing the tooth surfaces of the teeth beside the gaps between teeth, so that a user can clean all the teeth more quickly, and meanwhile, the problem of missing cleaning of the positions is less likely to occur.

In the brush sheet 80 of the present utility model, since the mounting hole 11 of the main body 10 is fixedly provided with the first bristle bundle 20A and the second bristle bundle 20B having different material and end surface areas, the gap between teeth and the tooth surface can not be cleaned simultaneously, and the first bristle bundle 20A and the second bristle bundle 20B can be used to clean the gap between teeth and the tooth surface of teeth during brushing, thereby increasing brushing efficiency and improving brushing fineness.

As shown in fig. 5 and 6, in the first preferred embodiment of the present utility model, the end portions of the plurality of bristle parts 20 and the plurality of posts 13 form the heat-fused body 40 by heat fusion so as to respectively and fixedly mount the plurality of bristle parts 20 in the plurality of mounting holes 11 of the body 10, and in other embodiments, after the bristle parts 20 are put through the corresponding mounting holes 11 of the body 10, all the bristles of the bristle parts 20 are gathered into one bundle by metal wires, so long as the bristle parts 20 comprise the first bristle bundles 20A and the second bristle bundles 20B, the effects of increasing brushing efficiency and brushing fineness of the present utility model can be achieved; the first preferred embodiment of the utility model is fixed by hot melt connection, so that the problems of rust of metal wires and bacterial breeding are avoided, and better installation stability can be obtained.

In the first preferred embodiment of the present utility model, as shown in fig. 1, the distance between the tip of the first bristle bundle 20A and the body 10 is greater than the distance between the tip of the second bristle bundle 20B and the body 10, that is, the distance between the tip of the first bristle 21A and the body 10 is greater than the distance between the tip of the second bristle 21B and the body 10, and by further designing the lengths of the first bristle 21A and the second bristle 21B protruding from the body 10 separately, the longer first bristle 21A protruding from the body 10 can protrude deeper into the crevice during brushing when the shorter second bristle 21B protruding from the body 10 brushes the tooth surface of the tooth, so as to achieve better cleaning effect.

In addition, in the first preferred embodiment of the present utility model, the body 10 includes a plurality of mounting holes 11, the brush piece includes a plurality of bristle parts 20 fixedly mounted to the plurality of mounting holes 11, in other embodiments, the body 10 may include only one mounting hole 11, and the brush piece includes only one bristle part 20 mounted to the mounting hole 11, so long as the bristle part 20 includes the first bristle bundle 20A and the second bristle bundle 20B, the effect of increasing brushing efficiency and brushing fineness of the present utility model can be achieved, and the first preferred embodiment of the present utility model employs the plurality of mounting holes 11 to mount the plurality of bristle parts 20, and the arrangement distribution of the plurality of bristle parts 20 can be designed according to specific requirements, so as to increase the degree of freedom of the product.

The present utility model is not limited to the above-mentioned embodiments, but is capable of modification and variation in all embodiments without departing from the spirit and scope of the present utility model.
