Description

toothbrush

technical field

The utility model relates to a toothbrush, in particular to a toothbrush with good cleaning effect.

Background technique

In modern society, a toothbrush is a necessary tool for maintaining oral hygiene. A good toothbrush can improve the cleaning effect of brushing teeth and reduce the occurrence of oral diseases. The existing toothbrush includes a brush head 90 as shown in Figure 4. An assembling surface 91 is provided on the head 90, and a plurality of planting holes (not shown) are formed on the assembling surface 91, and a bundle of bristles 92 is respectively arranged in the plurality of planting holes, and each bundle of bristles 92 has a spacing Several rows of bristle parts are formed on the assembly surface 91, and the bundles of bristles 92 in each bristle part are arranged alternately with the bundles of bristles 92 in adjacent bristle parts.

Yet when the user uses existing toothbrush to brush his teeth, only have several bundled bristles 92 that are aligned with this teeth gap and parallel can clean this teeth gap in each interdental gap, On the assembly surface 91 of the brush head 90, and gaps are formed between the bundles, so the contact area between the bundled bristles 92 of the brush head 90 and the interdental spaces is small, so the tooth cleaning effect is not good. All of the above are unsatisfactory parts of the prior art, so it can be seen that the prior art needs to be further reviewed and a feasible solution must be sought.

Contents of the invention

In view of the aforementioned shortcomings of the prior art, the purpose of this utility model is to provide a toothbrush, which can increase the cleaning effect of the toothbrush.

The main technical means taken for reaching the aforementioned purpose is to make the aforementioned toothbrush include:

A brush head, which has an assembly surface, and the assembly surface has a major axis and a minor axis;

A bristle body, the bristle body includes more than one row of short-axis bristles, more than one row of long-axis bristles and more than one bundle of bristles, the multiple rows of short-axis bristles are arranged on the short axis of the brush head assembly surface, the Long-axis bristle rows are arranged on the assembly surface and parallel to its long axis, the plurality of short-axis bristle rows intersect with the long-axis bristle row, and the plurality of bristle rows are respectively formed by a plurality of bristles arranged in high density, and the length More than one bristle bundle is arranged between the axial bristle row and the short axis bristle row.

The toothbrush described above, wherein a bundle of bristles is arranged at both ends of the bristle body.

Said toothbrush, wherein, the surface of the long-axis bristle row and the bristle bundle of the bristle body has bristles with different heights, so that the long-axis bristle row and the surface of the bristle bundle respectively form a contact surface with ups and downs.

The toothbrush described above, wherein the two short-axis bristle rows are respectively adjacent to the two ends of the bristle body, and adjacent to the two bristle bundles arranged at the two ends of the bristle body, the two short-axis bristle rows are arc-shaped, and are connected to the short axis of the brush head assembly surface. Parallel, each short-axis bristle row between the short-axis bristle rows at adjacent two ends is parallel to the short axis of the assembly surface.

The toothbrush described above, wherein, the bristles of the plurality of bristle bundles include bristles with different softness and hardness, which are respectively outer layer bristles, middle layer bristles and inner layer bristles from the outside to the inside, and the hardness is also divided into three types according to the three layers, The hardness increases from the outer layer to the inner layer.

Because each bristle row of the toothbrush is arranged in a high-density whole row on the assembly surface, when the user uses it, the bristle rows parallel to the teeth gap will fully and frequently contact the teeth gap, and because the utility model has an intersecting arrangement Therefore, no matter the user pushes the brush head back and forth in the direction parallel to the long axis or in the direction of the short axis, the bristle rows arranged in different directions can effectively contact the gap between the teeth to clean the tartar.

Detailed ways

Embodiments of the utility model are exemplified below in conjunction with the accompanying drawings to specifically illustrate the technical content of the utility model.

Please refer to Fig. 1 and Fig. 2, the utility model is a kind of toothbrush, mainly is provided with a bristle body 20 on a brush head 10, wherein:

The brush head 10 has an assembly surface 11, and the assembly surface 11 has a major axis and a minor axis;

The bristle body 20 includes more than one short-axis bristle row 21, more than one long-axis bristle row 22 and more than one bristle bundle 23, and the plurality of short-axis bristle rows 21 are arranged on the short axis of the assembly surface 11 of the brush head 10 Above, the long-axis bristle row 22 is arranged on the assembly surface 11 and parallel to its long axis, the plurality of short-axis bristle rows 21 intersect with the long-axis bristle row 22, and the plurality of bristle rows 21, 22 are respectively composed of a plurality of branches The bristles are arranged at a high density, and more than one bristle bundle 23 is arranged between the long-axis bristle row 22 and the plurality of short-axis bristle rows 21, and each bristle bundle 23 is gathered into a bundle with a plurality of bristles at a high density. Therefore, the plurality of bristle bundles 23 can be in contact with the teeth and between the teeth in a large area; in this preferred embodiment, a bristle bundle 23 is provided at both ends of the bristle body 20; wherein the two short-axis bristle rows 21 are respectively adjacent to the bristle body Both ends, and adjacent to the two bristle bundles 23 located at the two ends of the bristle body 20, the two short-axis bristle rows 21 are arc-shaped, and are roughly parallel to the short axis of the assembly surface 11 of the brush head 10, and the short-axis bristle rows 21 are adjacent to the two ends. Each minor-axis bristle row 21 between them is parallel to the minor axis of the assembly surface 11 .

In a preferred embodiment of the present invention, the bristle rows 21, 22, the bristle bundles 23 and the brush head 10 can be combined in the following manner, and the bristle rows 21, 22 and the bristle bundles are formed when most bristles are arranged in high density. After 23, the plurality of bristle rows 21, 22 and the plurality of bristle bundles 23 are placed in the mold, and the brush head 10 is made by plastic injection molding, and the bristle rows 21, 22 and the bristle bundles 23 are wrapped on the brush head 10.

Please refer to Figs. 1 to 3, in this preferred embodiment, the long-axis bristle row 22 and the bristle bundle 23 can have bristles with different heights, so that the surfaces of the long-axis bristle row 22 and the bristle bundle 23 respectively form a It has a contact surface with ups and downs, so that the bristle body 20 can fit the teeth better when brushing teeth; and the bristles of the plurality of bristle bundles 23 can include bristles with different softness and hardness, which are respectively outer bristles 231 and middle bristles 232 from outside to inside The bristles of the inner layer are 233, and the hardness is also divided into three types according to the three layers.
