The auxiliary protrusions 180 are distributed on the tongue cleaning protrusion pattern 160 at predetermined intervals. A plurality of the auxiliary protrusions 180 may be randomly distributed on the tongue cleaning protrusion pattern 160.

At this time, the auxiliary protrusion 180, along with the tongue cleaning protrusion pattern 160 to remove the tongue while scratching the floor of the user, and serves to improve the blood circulation of the floor of the floor with acupressure effect. For this purpose, the auxiliary protrusion 180 preferably has a shape of any one of a cone, a cylinder, and a hemisphere, and more preferably, it is designed in a cone shape.

The antifouling coating layer 190 may be disposed to cover the back surface of the toothbrush head 140 except for the tongue cleaning protrusion pattern 160 and the auxiliary protrusion 180. At this time, the antifouling coating layer 190 preferably has a thickness less than half of the height of the tongue cleaning protrusion pattern 160. This is because, when the thickness of the antifouling coating layer 190 is formed too thick, the protrusion height of the tongue cleaning protrusion pattern 160 may be lowered by the antifouling coating layer 190, thereby reducing the tongue removal efficiency.

The antifouling coating layer 190 is 5 to 30% by weight of polymethyl methacrylate, 1 to 20% by weight of urethane acrylate oligomer, 2,4-diphenyl-6- (2-hydroxy-4-ethoxyphenyl)- 1,3,5-triazine 1 to 5% by weight, 0.1 to 5% by weight surfactant and the antifouling coating composition composed of the remaining solvent toothbrush head 140 except for the tongue cleaning projection pattern 160 and the auxiliary projection 180 It can be formed by spray coating on the back of the back), drying and curing.

At this time, the antifouling coating composition should be used in combination with polymethyl methacrylate and urethane acrylate oligomer, when including only one of them there is a problem that elongation and hardness is lowered. That is, when only the urethane acrylate oligomer is used, the hardness property is excellent but the elongation is poor. When only the polymethyl methacrylate is used, the elongation is excellent, but the hardness property is poor.

If the amount of polymethyl methacrylate added is less than 5% by weight of the total weight of the antifouling coating composition, problems in elongation characteristics may occur. Conversely, when the amount of polymethyl methacrylate added exceeds 30% by weight of the total weight of the antifouling coating composition, problems may occur in hardness.

In addition, when the addition amount of the urethane acrylate oligomer is less than 1% by weight of the total weight of the antifouling coating composition, it may be difficult to secure the hardness. On the contrary, when the addition amount of the urethane acrylate oligomer exceeds 20% by weight of the total weight of the antifouling coating layer, the elongation is lowered, and there is a problem that a turbidity occurs.

Such 2,4-diphenyl-6- (2-hydroxy-4-ethoxyphenyl) -1,3,5-triazine is added for the purpose of improving adhesion. If the addition amount of 2,4-diphenyl-6- (2-hydroxy-4-ethoxyphenyl) -1,3,5-triazine is less than 1% by weight, it may be difficult to properly exhibit the effect of improving adhesion. have. Conversely, when the amount of 2,4-diphenyl-6- (2-hydroxy-4-ethoxyphenyl) -1,3,5-triazine added exceeds 5% by weight, the manufacturing cost is not increased further. It can act as a factor that raises the bay, so it is not economical.

Surfactants serve to improve hydrophilicity. When the amount of the surfactant added is less than 0.1% by weight of the total weight of the antifouling coating composition, there is a problem in that the hydrophilicity of the coating film is weakened. On the contrary, when the amount of the surfactant added exceeds 5% by weight of the total weight of the antifouling coating composition, there is a problem in that moisture becomes weak and durability and stain resistance decrease.

Tongue cleaner combined toothbrush excellent in tongue removal effect according to the embodiment of the present invention described above is formed on the back of the toothbrush head tongue cleaning projection pattern for cleaning the user's tongue bottom is formed integrally with the handle and the toothbrush head by injection molding. .
