Abstract

Disclosed is a toothbrush of a dual-layer bristle structure, the toothbrush comprising a toothbrush handle (10) and a toothbrush head (20). The toothbrush handle (10) is an elongated rod. The toothbrush head (20) is arranged at an end of the toothbrush handle (10), and comprises a base (21), an inner forming bristle portion (22) and a plurality of outer bristle-planting bristle portions (23), wherein an end of the base (21) is connected to the toothbrush handle (10); the inner forming bristle portion (22) has a plurality of first bristles (221) and is arranged on the base (21); and the outer bristle-planting bristle portions (23) are arranged on the base (21) and surround the inner forming bristle portion (22) at intervals, and each outer bristle-planting bristle portion (23) comprises a support base (232) and a plurality of second bristles (231), with the support base (232) being arranged on the toothbrush head (20) and the second bristles (231) being arranged on the support base (232). By means of arranging the second bristles (231) on the support base (232), the supporting performance of the second bristles (231) is improved, such that apart from having the function of cleaning gaps between teeth, the second bristles (231) also have the effect of massaging the gingiva.

Description

Toothbrush with double-layer bristle structure

Technical field

The application relates to a dental health product, especially a toothbrush with a double-layer bristle structure.

Background technique

Toothbrushes currently on the market, in addition to the general teeth cleaning function, the bristles usually also have a partial massage function, so that in addition to cleaning the teeth during the brushing process, it can further achieve the effect of massaging the gums; please refer to Figure 5 There is currently a toothbrush bristles configuration structure with a gum massage effect as described in Taiwan’s New Announcement No. TW M525109, which includes a brush head 11A provided with a plurality of first planting pores 111A, a plurality of second planting pores 112A, and The first bristles 12A, the second bristles 13A, and the second bristles 13A are respectively implanted in the first bristles 113A, the second bristles 112A, and the third bristles 113A. The third bristles 14A, and the free ends of the second bristles 13A and the third bristles 14A are round and arc-shaped, and have different length designs, so that the first bristles 12A are cleaned between teeth In the process, the second bristles 13A and the third bristles 14A are simultaneously used to massage the gums.

However, the toothbrush of the prior art sacrifices part of the bristles for cleaning the teeth in order to increase the massage effect. Instead, the free end of the bristles presents a curved structure with massage function, which causes the user to massage the teeth during the process of brushing. Due to the influence of the structure, the free end of the bristles cannot extend into the gap between the teeth because of the larger structure, thereby affecting the effect of cleaning the gap between the teeth.

Therefore, the toothbrush with massage function in the prior art has the above-mentioned problems and shortcomings in its overall structure, which needs to be improved.

Summary of the invention

In view of the shortcomings and deficiencies of the prior art, the present application provides a toothbrush with a double-layer bristle structure. The brush head is provided with an outer bristle portion, and the second bristle of the outer bristle portion is provided on a support seat. The outer bristles have both the purpose of cleaning between the teeth and massaging the gums.

In order to achieve the above-mentioned creative purpose of this application, the technical means adopted in this application is to design a toothbrush with a double-layer bristle structure, which includes:

A brush handle, which is a long bar body;

A brush head, which is arranged at one end of the brush handle and includes:

A base having a top surface, and one end of the base is connected to the brush handle;

An inner molded bristle portion, which has a plurality of first bristles, and the plurality of first bristles are projected on the top surface of the base;

A plurality of explanted bristles and bristles are arranged on the top surface of the base and surround the inner molded bristle section at intervals. Each of the explanted bristles and bristles includes a support seat and a plurality of second bristles. The support seat is arranged on the On the top surface, the plurality of second bristles are arranged on the support seat.

Furthermore, in the toothbrush with a double-layer bristle structure, the base further forms a first groove portion formed on the top surface of the base, and the inner molded bristle portion further includes a base The first bristles are projected on the base, the shape of the base corresponds to the first groove, and the base is selectively engaged with the first groove.

Furthermore, in the toothbrush with a double-layered bristle structure, the base includes a plurality of protrusions, the plurality of protrusions surround the base at intervals, and the peripheral edge of the first groove is provided with a plurality of recesses at intervals, The protrusions are selectively engaged with the recesses.

Further, in the toothbrush with a double-layered bristle structure, the base is formed with a plurality of second grooves, each of the second grooves is adjacent to each of the recesses, and each of the explanted bristle portions has the The support base can be selectively penetrated through each of the second groove portions.

Furthermore, in the toothbrush with a double-layer bristle structure, each of the first bristles is tapered relative to the other end of the base, and each of the second bristles is cylindrical.

The advantage of the present application is that by providing an inner molded bristle portion and an outer planted bristle portion on the brush head, the inner molded bristle portion is provided with first bristles, and the second bristle of the outer planted bristle portion is provided on the support seat. Such a structural design In addition to increasing the supportability of the second bristles through the support seat and achieving the effect of massaging the gums, the second bristles can also have the effect of cleaning the gaps between teeth.

Detailed ways

In conjunction with the drawings and the preferred embodiments of the application, the technical means adopted by the application to achieve the intended creation purpose are further described below.

Please refer to FIG. 1, the toothbrush with a double-bristle structure of the present application includes a brush handle 10 and a brush head 20. The brush handle 10 is a long rod.

Please refer to FIGS. 2 to 4, the brush head 20 is arranged at one end of the brush handle 10, and the brush head 20 includes a base 21, an inner molded bristle portion 22, and a plurality of explanted bristle portions 23. The base 21 has A top surface, and one end of the base 21 is connected to the brush handle 10. In this embodiment, the base 21 further forms a first groove 211, and the first groove 211 is formed on the top surface of the base 21; The bristle portion 22 has a plurality of first bristles 221, and the first bristles 221 protrude from the top surface of the base 21; the first bristles 221 are tapered relative to the other end of the base 21; in this embodiment, the inner The molded bristle portion 22 further includes a base 222. The base 222 has an upper side surface. The first bristles 221 are protruding from the upper side surface of the base 222. The first bristles 221 and the base 222 are integrally injected and molded. The shape of the base 222 corresponds to the first The groove portion 211, the base 222 can be selectively engaged with the first groove portion 211, the first groove portion 211 is a similar elliptical trough, and the base 222 is a similar elliptical block, but not limited to this; The base 21 and the base 222 may also be integrally formed; in this embodiment, the base 222 further includes a plurality of convex portions 223, which extend outward and surround the periphery of the base 222 at intervals; the periphery of the first groove portion 211 surrounds the interval concave There are a plurality of concave portions 212, and the convex portion 223 is selectively engaged with the concave portion 212; but not limited to this, the shape and arrangement of the convex portion 223 and the concave portion 212 can be changed according to the needs of the user, as long as the Combine the effect.
