Description

Electromotive tooth brush}

The present invention relates to an electric motor having a body case for housing an electric motor, and an operation shaft connected to the electric motor and driven by an electric motor. The operation shaft can be coupled with a stem having one end formed with bristles, The present invention relates to a power toothbrush capable of continuously applying a reciprocating vibration motion to a bristles by causing a turning center axis formed at a vertical or constant angle to a portion of a toothbrush to vibrate at a rotational center.

Generally, a toothbrush which is commonly used is a tool embodied by a plurality of bristles embedded on one end of a rod-like handle, and is a tool for the user to grasp the bristles by hand while rubbing the bristles on teeth. However, such a toothbrush is inconvenient for use because the user must manually perform the hand operation in the direction of brushing, and it takes a lot of time to brush the tooth.

In order to solve the problems of the conventional toothbrush, there has been proposed a technique relating to a powered toothbrush that automatically rotates or vibrates the bristles of a toothbrush using a driving force based on the principle of an electric motor or an electromagnet.

However, the conventional electric toothbrush has a complicated internal structure, which hinders the production of cheap and high-quality products and fails to meet the demands of various consumers.

Accordingly, the present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a toothbrush that is capable of performing a high-speed orbiting vibration movement around a turning center axis formed at a predetermined angle or perpendicular to the longitudinal direction of the operating shaft, And to provide a power toothbrush capable of easily and precisely cleansing teeth with a simple and simple brush bristle motion and having a simple structure and being able to be miniaturized with a low manufacturing cost.

In order to achieve the above object, the present invention has a simple structure in which a bristle of a stem can vibrate reciprocatingly in a vertical direction, and it can be rotated at a vertical angle or at a constant angle with the longitudinal direction of a stem assembly of an operating shaft, When the center shaft is formed and rotated about the turning center axis, the stem rotates in a direction perpendicular to the forming direction of the bristles, so that a driving mechanism capable of reciprocating motion is formed at the other end of the operating shaft, And the teeth are cleaned by imparting a swinging motion to the stem at the same time as the electric motor is driven.

As a result, the angle of the longitudinal axis of the stem, rather than the rotational motion of the stem with respect to the longitudinal axis of the stem, is swinging relative to the longitudinal axis of the handle body, It is possible to eliminate the dirt and the like attached to the teeth with a small stimulus and at the same time to obtain a massage effect, thereby maximizing the reliability of the user.

Fig.

In the electric toothbrush for cleaning teeth, an electric motor 800 is attached to the inside of the electric toothbrush body case 100, and the center of the inner diameter and the outer diameter of the electric motor 600 is eccentric The inner diameter of the eccentric cam 600 is fixedly assembled and the outer diameter of the eccentric cam 600 is assembled so as to be relatively rotatable relative to the eccentric cam hole 710 of the operation link 700, (720) engages with the driving projection (420) of the actuating shaft (400) so as to be capable of relative rotational movement.

The turning center axis 410 of the actuating shaft 400 formed at a predetermined angle or angle with the longitudinal direction of the stem assembly 430 of the actuating shaft 400 is fixed to the inside of the electric toothbrush body case 100, The operation shaft 400 can be rotated by the rotation of the operation shaft 400 in accordance with the rotation of the electric motor 800. The operation shaft 400 can be rotated in a direction perpendicular to the longitudinal direction of the bristles 210, And the engaging protrusion 311 of the bracket 300 and the engaging protrusion 311 of the bracket 300 are engaged with the stem assembly 430 of the actuating shaft 400 formed at one end of the actuating shaft 400 The combination of the stem 200 and the bracket 300 which are fixed and assembled with each other by the engaging groove 440 of the operating shaft 400 is vibrated in a revolving motion so that the bristles 210 are vertically moved in the longitudinal direction of the bristles 210 Which is necessary to clean teeth. Appropriate exercise can be obtained.

In addition, the electric toothbrush body may be used as an electric driver having a complex function so that not only the stem 200 but also a cosmetic brush or the like may be combined to be used as a makeup aid.

A battery 900 as a power source for the electric motor 800 is installed inside the electric toothbrush body case 100 so as to drive the electric motor 800. It is preferable that an operation switch 110 is formed on the outside of the electric toothbrush body case 100 so that the battery 900 is connected to the electric power source to turn the electric motor 800 on and off.
