Description

Toothbrush sterilizing device {APPARATUS FOR STERILIZING TOOTHBRUSH}

The present disclosure relates to a toothbrush sterilizing device for sterilizing toothbrushes.

Toothbrushes are used to remove tartar and food particles from teeth. A toothbrush is a product that you put in your mouth every day and requires cleanliness.

If you leave your toothbrush alone after brushing your teeth, bacteria and germs can easily multiply due to the moisture or organic substances remaining on the toothbrush bristles. Using a toothbrush contaminated with these microorganisms increases the risk of developing various oral diseases such as periodontitis.

Therefore, various devices are being developed to sterilize toothbrushes to suppress the growth of bacteria after use.

However, in the case of conventional toothbrush sterilization devices, the interior is not easy to clean, so when the inside of the sterilization device is contaminated by a toothbrush, it is difficult to remove or clean it. Accordingly, in the past, the sterilizing device had no choice but to be used for a long time without being cleaned at all, which could lead to the toothbrush being contaminated by the sterilizing device.

In addition, as it was developed solely to focus on the toothbrush sterilization function, it has the disadvantage of being inconvenient to use and having poor functionality.

Recently, the demand for hygiene and cleanliness is increasing due to the spread of viruses. Therefore, providing an improved conventional toothbrush sterilizing device can provide many advantages to users.
