Description

interdental brush

technical field

The utility model relates to an interdental brush, in particular to an interdental brush which has soft elastic bristles and does not cause gum injury during the cleaning process.

Background technique

Oral hygiene is an extremely important part of personal cleaning work, and whether it is clean or not is critical to the health of individual teeth. The basic tools that ordinary people use to clean their mouth are nothing more than toothbrushes, toothpicks, dental floss sticks, etc. Among them, toothbrushes are usually used for routine cleaning tasks, such as brushing teeth after getting up and before going to bed; toothpicks and dental floss sticks are usually used for meals Finally, it is used to remove vegetable residues between teeth, mainly because toothpicks and dental floss sticks are slender, and their tips or dental floss are smaller than the space between teeth, so they can go deep into the teeth to remove residual vegetable residues. However, most of the functions of this type of flossing tools are limited to the removal of interdental residues. They do not have a cleaning effect on the teeth themselves, especially on the adjacent interdental areas. For these specific parts, traditional toothbrushes are useless.

For this reason, so-called interdental brushes have appeared in the market. The main function is to clean the teeth. Its structure is shown in FIG. , the bristle structure mainly uses the iron wire 81 folded into two strands for helical twisting, and the bristles 82 are interspersed during the twisting process, and then the end of the iron wire 81 is combined with one end of the handle 70 to form an interdental brush.

Since the bristle structure 80 of the aforementioned interdental brush is elongated, it can easily enter the interdental space, and use the bristle 82 to brush the tooth structure between adjacent teeth between advance and retreat.

Although the aforementioned interdental brush has a cleaning effect on the interdental spaces, because of the bristle structure 80, the bristle 82 is interspersed between the twisted iron wires 81, and the iron wire 81 itself is a rigid material, and the combined bristle structure 80 must be fine. Due to its long shape, the diameter of the iron wire 81 is also small. In this case, the effect of a serrated blade may appear. Once the iron wire 81 directly touches the gums, and when the force is applied improperly, the gums may be injured. From the above, it can be seen that the structure of the existing interdental brush needs to be further reviewed and a feasible solution must be sought.

Utility model content

The main technical problem to be solved by the utility model is to overcome the above-mentioned defects in the prior art, and provide an interdental brush with soft elastic bristle structure, which can ensure that the gums are not damaged during the interdental brushing process, and both Cleaning efficacy and safety in use.

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

a hard body, which is strip-shaped, with a handle at one end and an elongated base at the other end;

A coating layer is made of soft elastic material and is coated on the outside of the hard body; the coating layer covers the handle part to form a handle, and the surface of the coating layer corresponding to the base part forms several The elastic bristles are arranged radially;

The above-mentioned interdental brush has a soft and elastic bristle structure formed on the base at one end of the hard body. With the support of the elongated base, it can effectively penetrate into the interdental space, and the covering layer outside the base can move in and out of the interdental space. It is guaranteed not to hurt the gums, and the elastic bristles formed by the covering layer at the base can effectively clean the interdental structure; thus, the aforementioned interdental brush can take into account both the interdental cleaning effect and the safety of use.

Detailed ways

Regarding a preferred embodiment of the present utility model, first please refer to Fig. 1, which mainly forms a cladding layer 20 outside a hard body 10, and utilizes the cladding layer 20 on one end of the hard body 10 Form the bristle structure 21; please refer to FIG. 2, the hard body 10 can be made of plastic material by injection molding, and it is generally in the shape of a straight strip. The handle portion 11, in this embodiment, the handle portion 11 has a non-flat concave-convex structure, for example, a continuous concave surface 111 is formed on the relative radial surface in the up and down direction of the handle portion 11, so that the handle portion 11 presents a The wide and flat cross-sectional shape (please refer to Fig. 3 for cooperation), and the handle portion 11 forms a plurality of convex portions 112 on the relative radial surfaces in the front and rear directions; Outside of cladding 20.

Still please refer to shown in Fig. 2, this hard body 10 forms a slender base 12 at the other end of the handle 11, as the basis of the bristle structure on the interdental brush of the present utility model, because the base 12 and the handle The part 11 is an integral structure, so the base part 12 has appropriate rigidity, which can support the bristle structure to smoothly enter and exit between the teeth.

Furthermore, the coating layer 20 is formed outside the hard body 10 by a soft elastic material (such as silica gel) by means of injection. Please refer to FIG. 1 and FIG. A handle 21 is formed at the handle portion 11 at one end of the solid body 10, and several elastic bristles 22 are formed on the surface of the base portion 12 at the other end of the coating layer 20 corresponding to the hard body 10, thereby forming a soft and elastic bristle structure. , in this embodiment, the elastic bristles 22 are in the shape of a pointed cone, the base of which has a smaller outer diameter and decreases upwards to form a cone, and the elastic bristles are arranged radially in multiple rings on the base 12 .

It can be understood from the foregoing description that the specific structure of the interdental brush of the present invention is mainly to form a soft elastic bristle structure on the base 12 at one end of the hard body 10. With the support of the elongated base 12, it can effectively Go deep into the teeth, and the elastic bristles 22 formed by the coating layer 20 at the base 12 can effectively clean the interdental structure; as for the coating layer 20 outside the base 12, it can be used based on its soft and elastic characteristics. In addition, the covering layer forms an incomplete covering on the handle part of the hard body, making the handle moderately soft and hard, and improving the comfort when holding. Therefore, the use of the interdental brush with the aforementioned structure can take into account the interdental cleaning effect and use safety.
