Description

상하방향 왕복스윙운동하는 진동브러쉬를 구비한 전동칫솔{an electric toothbrush having a upward and downward swinging brush} An electric toothbrush having a upward and downward swinging brush

본 발명은 상하방향으로 왕복스윙운동하는 진동브러쉬를 구비한 전동칫솔에 관한 것으로서, 더욱 상세하게는 좌우왕복회전운동 또는 상하왕복스윙운동(이하에서 사용자 시각을 기준으로 "상하방향의 왕복스윙운동"으로 명칭함)하는 전동칫솔의 작동축에 연결된 진동브러쉬가 칫솔모를 상하방향으로 왕복스윙운동할 수 있게 고안된 전동칫솔에 관한 것이다.The present invention relates to an electric toothbrush having a vibrating brush that reciprocates in a vertical direction, and more particularly, a left and right reciprocating rotational motion or a vertical reciprocating swing motion (hereinafter, based on the user's point of view, "reciprocating swinging motion in the vertical direction"). It relates to an electric toothbrush designed so that the vibrating brush connected to the operating shaft of the electric toothbrush can reciprocate the bristles in the vertical direction.

전 세계의 대부분 치과의사들은 올바른 칫솔사용방법으로 수직방향 양치질을 추천하고 있으나, 일반적으로 사용되고 있는 '막대형 일반칫솔', '수평회전식 전동칫솔', '수직회전식 2회전축 전동칫솔' 등은 사용이 불편하다거나 수직방향으로 치아 사이사이까지 깨끗이 닦기 어렵다거나 크기가 크고 구조가 복잡하여 생산비용이 많이 들고 상용화가 어려운 등의 문제점들이 있다.Most dentists around the world recommend vertical brushing as the correct way to use a toothbrush, but the commonly used 'rod-type general toothbrush', 'horizontal rotating electric toothbrush', and 'vertically rotating 2-axis electric toothbrush' are not recommended for use. There are problems such as inconvenient, difficult to clean between teeth in the vertical direction, high production cost and difficult commercialization due to large size and complex structure.

' 일반 막대형 칫솔'은 손을 움직여 양치질을 하므로 사용이 불편하고 시간이 많이 걸리는 문제점이 있고, ' 수평회전식 전동칫솔'은 칫솔모의 회전방향이 치아와 수평을 유지하고 있어서 어금니 등 입 안쪽 치아의 사이사이까지 깨끗이 닦기 어려우며, ' 수직회전식 2회전축 전동칫솔'은 구조가 복잡하고 생산비용이 많이 들고 부피가 커서 사용이 불편하다는 한계를 지니고 있다.The 'general rod-type toothbrush' is inconvenient to use and takes a lot of time to brush teeth by moving your hands, and the 'horizontal rotating electric toothbrush' maintains the rotation direction of the bristles horizontally with the teeth, so It is difficult to clean even between the teeth, and the 'vertically rotating 2-axis electric toothbrush' has limitations in that it is inconvenient to use because of its complicated structure, high production cost, and large volume.

따라서 본 발명의 주목적은 칫솔모를 상하방향으로 왕복스윙운동시키는 전동칫솔을 개발하여 사용자가 치아 사이사이까지 깨끗하고 쉽게 양치질을 할 수 있도록 하는 데 있다.Therefore, the main object of the present invention is to develop an electric toothbrush that reciprocates the bristles in the vertical direction so that the user can clean and easily brush between teeth.

또한, 본 발명의 다른 목적은 상하방향 왕복스윙운동의 진동브러쉬의 구조를 단순화하여 생산비용을 낮추고 상용화 가능성을 높이는 제품을 개발하는 데 있다.In addition, another object of the present invention is to simplify the structure of the vibrating brush of the vertical reciprocating swing motion to develop a product that lowers the production cost and increases the commercialization possibility.

아울러, 본 발명의 다른 목적은 혼자서는 양치질을 제대로 하지 못하는 노인,어린이,유아,장애인 등이 깨끗하고 쉽게 양치질을 할 수 있는 제품을 개발하여 인류의 건강증진에 이바지하는 데 있다.In addition, another object of the present invention is to contribute to the promotion of human health by developing products that allow the elderly, children, infants, the disabled, etc., who cannot brush their teeth properly by themselves, to brush their teeth cleanly and easily.

상기 목적을 달성하기 위하여 본 발명의 전동칫솔은, 칫솔대와 상기칫솔대에 착탈가능하게 설치되는 브러쉬부로 이루어진 전동칫솔에 있어서, 상기 칫솔대는 내측에 구비되는 구동모터에 설치된 구동축의 회전을 상하방향의 왕복스윙운동으로 변환하여 브러쉬부에 제공하는 스윙캠과 그 작동축을 포함하고, 상기 브러쉬부는 상기 전동칫솔대의 작동축으로부터 상하방향의 왕복스윙운동을 전달받아 상하방향으로 왕복스윙운동하는 진동브러쉬와; 상기 진동브러쉬의 외측에 배치되는 보호커버와; 상기 보호커버 내부에 배치되어 진동브러쉬의 진동을 완화해주는 진동완화장치로 구성한 것을 특징으로 한다.In order to achieve the above object, the electric toothbrush of the present invention is an electric toothbrush comprising a toothbrush rest and a brush part detachably installed on the toothbrush rest, wherein the toothbrush rest reciprocates in the vertical direction by rotating a drive shaft installed in a driving motor provided inside the toothbrush rest. a vibrating brush comprising a swing cam and its operating shaft converted into a swing motion and provided to the brush unit, wherein the brush unit receives a vertical reciprocating swing motion from the operating shaft of the electric toothbrush rest and performs a vertical reciprocating swing motion; a protective cover disposed outside the vibrating brush; It is characterized in that it consists of a vibration damping device disposed inside the protective cover to relieve the vibration of the vibrating brush.

또한 본 발명에 따르면, 상기 진동브러쉬는 그 일측에 칫솔모가 구비되고 타측이 상기 작동축의 전방과 착탈 가능하게 결합되며 그 끝단에 구비된 탄성후크가 작동축에 형성된 체결홈에 고정되도록 진동브러쉬축을 구성한 것을 특징으로 한다.In addition, according to the present invention, the vibrating brush is provided with bristles on one side, the other side is detachably coupled to the front of the operating shaft, and the elastic hook provided at the end is fixed to the fastening groove formed in the operating shaft. characterized in that

그리고 본 발명에 따르면, 상기 보호커버는 하면에 개방홀이 형성되고 일측이 칫솔대에 착탈가능하게 결합됨에 따라 진동브러쉬의 칫솔모만이 외측으로 돌출되도록 하며 끝단에 체결홈을 통해 칫솔대에 끼움고정할 수 있도록 구성한 것을 특징으로 한다.And according to the present invention, the protective cover has an open hole formed on the lower surface, and as one side is detachably coupled to the toothbrush rest, only the bristles of the vibrating brush protrude outward, and can be fitted and fixed to the toothbrush rest through the fastening groove at the end. It is characterized in that it is configured so that

아울러 본 발명에 따르면, 상기 칫솔대에는 구동모터의 온/오프 및 속도를 제어하는 모터제어부가 포함되어 있고, 그 내측에 고무·실리콘등을 소재로한 방수장치가 포함되어 있어 칫솔대 내부로 물이 흘러들어가지 않도록 구성한 것을 특징으로 한다.In addition, according to the present invention, the toothbrush rest includes a motor control unit for controlling on/off and speed of the driving motor, and a waterproof device made of rubber, silicone, etc. is included inside the toothbrush rest, so that water flows into the toothbrush rest. It is characterized in that it is configured not to enter.

상술한 바와 같이, 본 발명의 전동칫솔은 칫솔모를 상하방향으로 왕복스윙운동시켜서 칫솔모가 수직방향으로 치아의 결을 따라 움직이므로 낮은 회전속도와 진동으로도 충분한 양치효과를 낼 수 있어서 잇몸손상이나 치아손상을 막을 수 있고 사용자가 양치질을 쉽고 깨끗하게 할 수 있는 향상된 기능을 갖도록 하는 효과가 있다.As described above, the electric toothbrush of the present invention reciprocates the bristles in the vertical direction so that the bristles move along the grain of the teeth in the vertical direction, so that a sufficient brushing effect can be achieved even with low rotational speed and vibration. It has the effect of preventing damage and having an improved function that allows users to brush their teeth easily and cleanly.

또한, 본 발명의 전동칫솔은 브러쉬부의 구조가 단순하고 생산비용이 절감되어서 상용화에 성공할 가능성이 매우 높아지는 효과가 있다.In addition, the electric toothbrush of the present invention has a simple structure of the brush part and reduced production cost, so that the possibility of commercialization is very high.

아울러, 본 발명의 전동칫솔은 사용법이 간단하여 일반인 뿐만 아니라 어린이, 노약자, 환자, 장애인 등도 치아건강을 유지하는데 기여하는 효과가 있다.In addition, the electric toothbrush of the present invention has an effect of contributing to maintaining dental health not only for the general public, but also for children, the elderly, patients, the disabled, etc.
