ELECTRIC TOOTHBRUSH HAVING GUM DAMAGE PREVENTION FUNCTION
Document Type and Number:
WIPO Patent Application WO/2016/175490
Kind Code:
A1
Abstract:
The present invention relates to an electric toothbrush having a gum damage prevention function and, more specifically, to an electric toothbrush having a gum damage prevention function, the electric toothbrush being capable of, when a user moves the tooth-brushing position to upper teeth or lower teeth, appropriately changing the rotational direction of a toothbrush head automatically even if the user does not particularly change the rotational direction of the toothbrush head, thereby enabling safe and effective tooth brushing. The electric toothbrush having a gum damage prevention function according to the present invention comprises: a toothbrush main body; a driving motor embedded in the toothbrush main body so as to generate a rotational force; a rotational toothbrush rod which is rotated by the driving motor and has a toothbrush head on which a plurality of toothbrush bristles are implanted; a switching member having a contact part which is disposed in contact with the toothbrush head so as to move in a forward or reverse direction by being in contact with the upper teeth or lower teeth during tooth brushing; and a switching means for generating a switching signal for converting the rotational direction of the driving motor to a forward or reverse direction in response to the forward or reverse direction movement of the switching member. The electric toothbrush having a gum damage prevention function according to the present invention has an advantage in that, when the user moves the position of the toothbrush head to the upper teeth or lower teeth during tooth brushing, the rotational direction of the toothbrush head is automatically converted in a direction which does not damage gums and shows an excellent washing effect by means of the operation of the switching member and the switching means. Accordingly, the electric toothbrush having a gum damage prevention function according to the present invention is convenient to use, is safe, and has an effect of improving washing efficiency since it is not necessary for a user to change the rotational direction of the toothbrush head every time by controlling a separate control button, as in the conventional art.
