JP3219740U - Spherical toothbrush - Google Patents

Abstract

To provide a spherical toothbrush that can cleanly clean the back side of upper and lower teeth, the back side of upper and lower gums, the back side of upper and lower back teeth, and upper and lower gingiva without any spots. The shape of the brush part of the toothbrush is a sphere. The hard core part of one spherical brush part and the hard core part of the other spherical brush part are connected by a flexible fine hard urethane rod 8. The tip portion of the toothbrush handle rod 1 has a female screw structure, the tip of the toothbrush connecting rod 3 has a spherical brush portion, and the terminal portion of the connecting rod has a male screw structure with a screw-type attachment / detachment structure.

Description

  The present invention relates to a shape function structure of a toothbrush.

  Conventional toothbrush shapes are rectangular and oval. However, with existing toothbrushes, it is difficult to clean the back of the upper and lower teeth, the back of the upper and lower gums, and the back of the upper and lower back teeth without spots.

  There is a need for a toothbrush that can brush the upper and lower teeth, the upper and lower gums, the upper and lower back teeth, and the upper and lower gums without brushing.

  The shape of the toothbrush part is a sphere. The base of flocking of a spherical toothbrush is a soft flexible spherical urethane sponge, and the surface of the soft flexible spherical urethane sponge is hard urethane. Put a toothbrush brush on the hard urethane surface. The core hard urethane of the spherical toothbrush is connected and fixed with a screw-type connecting rod. The spherical toothbrush core is completed by connecting and fixing the spherical toothbrush core and the spherical toothbrush core with a flexible, micro-hard urethane connecting rod.

  The connecting part of the spherical toothbrush core and the spherical toothbrush core is a flexible fine rigid urethane rod that can freely move up and down, 360 ° freely fits the front and back of the upper and lower teeth, the front and back of the upper and lower gums, the front and back of the upper and lower back teeth, and the upper and lower gingiva. Hygienic cleaning is possible with a brushing effect. A V-shaped part concave function structure in which the core of the spherical toothbrush and the core of the spherical toothbrush are connected with a flexible fine rigid urethane connecting rod, and the convex function structure on both sides of the part, the gap between the upper and lower teeth and the upper and lower teeth and gums Hygienic cleaning is possible with a brushing effect that fits the base of the skin and is free of spots. A clean brushing effect prevents tooth decay, scary periodontal disease, and other oral diseases, and maintains a hygienic oral environment.
