Description

Automatic dental floss

The present invention relates to a fully automatic dental floss, and more particularly, to a fully automatic dental floss that enables automatic flossing to be performed by reciprocating the floss by pressing an operation button.

In addition to regular dental health checks to remove dental plaque and professional cleaning, personal care in dental hygiene is essential to maintaining the health and appearance of teeth and gingiva. The most familiar and common means of meeting this need is a bristle toothbrush. For example, Korean Patent Publication No. 10-2017-0062779 (2017.06.08.) discloses a toothbrush.

However, toothbrushes are effective in cleaning most parts of teeth, dentures and orthodontic appliances, but have limitations in removing plaque between teeth. To solve this, dental floss is used. However, in the case of conventional dental floss, flossing is performed manually by cutting the dental floss and inserting the dental floss into the oral cavity in a state where the floss is wound around the finger, which is cumbersome and unsanitary, and the removed foreign matter gets on the user's hand. there was

It becomes. At the same time, referring to FIGS. 12 and 13 , the protruding member 623 pushes the guide member 250 while rotating about the center of the horizontal axis 622, so that the guide member 250 moves forward. It rotates around the magnetic axis 240. Accordingly, while the pair of hook members 230 also rotate around the pendulum shaft 240, the dental floss inserted between the user's teeth performs a reciprocating motion. As a result, if the user presses the power button 710 while the floss is inserted between the user's teeth, flossing is automatically performed.

As such, it will be understood that the technical configuration of the present invention described above can be implemented in other specific forms without changing the technical spirit or essential features of the present invention by those skilled in the art to which the present invention belongs.

Therefore, the embodiments described above should be understood as illustrative and not restrictive in all respects, and the scope of the present invention is indicated by the claims to be described later rather than the detailed description, and the meaning and scope of the claims and their All changes or modified forms derived from equivalent concepts should be construed as being included in the scope of the present invention.
