When the bristle unit 13 has a replaceable structure, the coupling tab 14 may be formed on the connection neck unit 12. A toothbrush having such a structure will be described below.

Figure 2 shows an embodiment of the separation and coupling structure of the toothbrush according to the present invention.

Referring to FIG. 2, the bristle unit 13 includes a base 131 having a coupling hole 135 formed thereon; A fixing plate 132 formed above the base 131; And a bristle 133 disposed on the fixed plate 132. The base 131 may have a box shape in which one direction as a whole has a larger rectangular cross section than the other direction, and the fixing plate 132 may be formed on the upper surface of the base 131. The fixing plate 132 may have a shape protruding from an upper surface of a rectangular shape, and may have a function of fixing the bristles 133. The root portion of the bristles 133 may be fixed to the fixing plate 132, and each bristle 133 may be integrally formed with the fixing plate 132. In such a structure, the fixing plate 132 may be made of the same or similar material as the bristles 133.

The coupling tab 14 can be made in a variety of structures and is not limited to the embodiment presented.

Figure 3 shows an embodiment of the bristles applied to the toothbrush according to the present invention.

Referring to Figure 3, each bristles are fixed hair 32; Elastic hair 33 extending from the fixed hair 32; And it consists of a contact hair (31) extending from the elastic hair (33). The bristles 133 may be integrally formed with the fixing plate 132 formed above the base 131, or may be formed independently of the fixing plate 132 and combined. Referring to the right part of FIG. 3, a linear contact hair 31 extending with the same diameter may be formed integrally with the fixing plate 132 and may extend vertically. In addition, a silicon material having relatively rigidity is coated with a large thickness on the lower portion of the contact hair 31 to form the fixed hair 32. Thereafter, the elastic hair 33 may be formed by coating with a small thickness above the fixed hair 32. The fixed hair 32 may have a larger length than the elastic hair 33, and the contact hair 31 formed on the upper portion of the elastic hair 33 may have a smaller length than the elastic hair 33. . In addition, the fixed hair 32 may have a structure that does not bend relatively easily while having a large elasticity, and the contact hair 31 may have a characteristic that can be easily bent while having a relatively small elasticity. The elastic hair 32 and the contact hair 31 may be made by making the fixed hair 32 to a length at which the contact hair 31 is formed and then cutting the circumferential surface. As described above, the toothbrush head 133 may be made of a silicone material, preferably made of antibacterial silicone. The antimicrobial silicone may be, for example, a silicone or silicone elastomer immobilized with a silver-based inorganic antimicrobial agent, a chitosan antimicrobial agent, an ammonium antimicrobial agent or a similar antimicrobial component. The bristles 133 may be made of silicone or silicone elastomer, or may be made by coating a nylon or polyester material with silicone or silicone elastomer. In order to improve the tooth brushing effect, it is advantageous that the bristles have a small elastic modulus, a small coefficient of friction, and a high elasticity. For example, the bristle 133 or the contact hair 31 is Shore Hardness 20 to 50 (A); Elongation 50 to 300%; Tensile strength 50 to 80 kgg/cm 2; Modulus of elasticity 0.8 to 3.0 Mpa; And a friction coefficient of 0.05 to 0.2. Additionally, the bristles 133 may be made to have hydrophobicity, and may include, for example, chlorosilane or a silane-based compound similar thereto, or may include hydrophobic silica. As described above, when the bristles are made of a silicone or silicone elastomer material having an antibacterial component and a characteristic to effectively brush teeth, the brushing effect can be improved. In addition, even if used for a long period of time, the brush head is not damaged and the brushing effect is maintained. The toothbrush head 133 may be made of various silicone materials and is not limited to the exemplary embodiments presented.

In the toothbrush having a silicone bristle structure according to the present invention, the bristle is made of a silicone material so that damage to the teeth or gums is prevented during the brushing process, and the brushing teeth are effectively turned by elasticity. In addition, the toothbrush according to the present invention prevents dental diseases by antibacterial silicone bristles.
