Description

ORAL CARE DEVICE AND MANUFACTURING METHOD OF THE SAME

The present invention relates to an oral care device and a method for manufacturing the same, and more particularly, to an oral care device configured to accurately couple a substrate module to a required position of a bracket and a manufacturing method thereof.

The oral cavity is a very important organ for breathing and food intake. If the oral cavity is not kept clean, plaque and tartar may form around the teeth and gums.

Such plaque and tartar multiply in the oral cavity and cause gum diseases such as periodontitis and gingivitis. Accordingly, although the oral rinse is used to suppress bacterial growth in the oral cavity, there is a problem in that the oral sterilization treatment cannot be effectively performed only with the mouthwash.

Accordingly, various oral sterilizers have been developed to sterilize bacteria in the oral cavity by irradiating the LED light source to the teeth and gums.

However, since the conventional oral sterilizer does not provide a separate bracket for supporting the flexible substrate having the LED light source for intraoral sterilization, there is a problem in that the position of the LED light source for sterilization is not accurately placed at the required position.

In addition, when a plurality of flexible substrates are provided in the oral sterilizer, the protective part molding operation must be performed for each flexible substrate, so that the manufacturing process is complicated and the manufacturing time is long.

Therefore, various research and development on the oral sterilizer made to precisely arrange the LED light source at the required position and simplify the manufacturing process are being made.
