Description

Toothbrush for generating negative ion and sterilization

The present invention relates to a toothbrush having an anion generating and sterilizing function, and more particularly, by placing a battery, UV LED and a light guide rod in the toothbrush to radiate a light source and anion for sterilization, to keep the toothbrush clean at all times and It relates to a toothbrush having anion generating and sterilizing function which can easily remove calculus.

In general, a toothbrush is a sanitary tool that is used several times a day. The brush part of the toothbrush is inhabited by invisible bacteria due to proper moisture and fine food waste. This makes toothbrushes the decisive route for bacterial transmission of pathogens that are deadly to the body.

As such, in order to prevent the toothbrush from being used as a path for bacterial transmission, conventionally, a method of storing the toothbrush in a toothbrush sterilizer such as ultraviolet rays, or soaking it in hot water and disinfecting it is used.

However, the method of storing the toothbrush in the toothbrush sterilizer, such as ultraviolet rays, has the problem that the user has to purchase a separate toothbrush sterilizer and the cost burden increases. There is a problem that deformation of the entire toothbrush, including.

The present invention was created to solve the conventional problems as described above, by placing a battery and a UV LED and a light guide rod in the toothbrush by radiating a light source and anion for sterilization, to maintain the cleanliness of the toothbrush at all times and the tartar in the oral cavity An object of the present invention is to provide a toothbrush having anion and sterilization function that can be easily removed.
