Description
The present invention relates to an electric toothbrush having a function of preventing damage to a gum, and more particularly, to a toothbrush which is capable of automatically rotating the toothbrush head when the user moves the toothbrushing position to the upper teeth or the lower teeth without changing the rotation direction of the toothbrush head. The present invention relates to an electric toothbrush having a function of preventing damage to a gum that can be appropriately changed in direction and safely and effectively brushing teeth.
Generally, a toothbrush is a cleaning tool that removes foreign substances adhered to teeth or protects against harmful bacteria, and a hand-held toothbrush for holding a handle and moving the user in a predetermined direction to clean the toothbrush is mainly used.
The manual toothbrush method includes a scraping method in which the toothbrush is reciprocated against the teeth, a bass method in which the teeth are tilted by about 45 degrees to oscillate the teeth back and forth between the teeth, the teeth and gums Or the like, or the like.
Among the methods of using the manual toothbrush described above, the bath method, the up-down or circular motion method has an advantage of being relatively easy to wash and reducing the damage of the gum, but it is difficult to do so due to the muscle structure of the hands and arms. In addition, it is difficult to acquire proper brushing method easily. In addition, since it is cumbersome to perform vertical movement and circular movement of the toothbrush even if it is a real expert, in most cases, the toothbrush is moved in the forward and backward directions to brush the teeth.
However, the method of brushing the manual toothbrush has a disadvantageous effect on oral hygiene, such as a low removal efficiency of foreign substances and an inflammation on the gums, and thus electric toothbrushes rotated by an electric motor such as a driving motor have been widely used.
For example, as shown in Korean Registered Patent Publication No. 10-1412007, a powered toothbrush is used to wipe a tooth by rotating a toothbrush head in which a plurality of bristles are implanted by driving an electric motor built in the electric toothbrush, , It is recognized that it is a good tool to motivate the dental care of children who are not able to brush their teeth as well as general adults, while the exercise of the arm is unnecessary even for an elderly person, have.
However, the electric toothbrush can not be wiped up and down as the toothbrush head rotates only in one direction, and there is a limit to damage the gums in the course of rotation.
To solve these drawbacks, there has been proposed a bidirectional electric toothbrush disclosed in Korean Utility Model Registration No. 20-0374644 registered in the Republic of Korea.
As shown in FIG. 1, the bidirectional electric toothbrush includes a rechargeable battery 8 and a motor 7 inside a
The bidirectional electric toothbrush described above operates the
However, the bidirectional electric toothbrush has a disadvantage in that it is very troublesome to use the
In addition, since it is necessary to stop the brushing operation in the process of moving the motor change-over
In addition, the bidirectional electric toothbrush described above may cause serious irritation to the tooth when the direction of rotation of the toothbrush blade is changed due to carelessness or malfunction of the user, or when changing the cleaning position without switching the
SUMMARY OF THE INVENTION The present invention has been made in view of the above-described subject matter, and it is an object of the present invention to provide a toothbrush device that automatically changes the direction of rotation of a toothbrush head when a user moves a toothbrushing position to an upper tooth or a lower tooth without changing the rotation direction of the toothbrush head. The present invention provides a toothbrush that has a function of preventing damage to a gum that can effectively perform brushing.
In order to achieve the above object, the present invention provides a power toothbrush having a function of preventing damage to a gum, the toothbrush comprising: a toothbrush body; A drive motor incorporated in the toothbrush body to generate a rotational force; A rotating toothbrush having a toothbrush head rotated by the driving motor and having a plurality of bristles implanted; A switching member having a contact portion disposed in contact with the toothbrush head so as to flow in a forward direction or a reverse direction in contact with the upper teeth or the lower teeth in the course of brushing; And switching means for generating a switching signal for converting the rotational direction of the driving motor in the forward and reverse directions in accordance with the forward and backward flow of the switching member.
The return member may be further configured to apply a return force to move the switching member to the neutral position in a state in which the switching member is moved in the forward or reverse direction.
The switching member includes a switching rod rotatably installed on the toothbrush main body and formed with the contact portion bent at an end thereof, and a switching cam interposed between the switching bar and the switching bar, And a tact switch installed in proximity to generate a switching signal corresponding to the flow.
The tact switch includes a first tact switch disposed on one side of the switching cam to generate a switching signal in forward rotation, a second tact switch disposed on the other side of the switching cam to generate a switching signal in the reverse rotation, And the return member may be constituted by the first tact switch and the elastic member provided on the second tact switch so as to apply an elastic force to the switching cam.
Preferably, the toothbrush body is provided with a rod mounting portion having a rod insertion hole into which the switching rod is inserted, and the tact switch is disposed at one side of the switching cam to generate a switching signal at the time of forward rotation, And a second tact switch disposed on the other side of the switching cam to generate a switching signal in the reverse rotation, wherein the return member includes a rod housing installed in the tact switch and having a moving hole communicating with the inner housing space, A driving rod inserted into the rod housing and moving forward and rearward and formed with a latching jaw, and an elastic member inserted in the rod housing and applying an elastic force to the driving rod.
According to the electric toothbrush of the present invention, when the user moves the position of the toothbrush head to the upper teeth or the lower teeth in the process of brushing the teeth, the rotation of the toothbrush head It has an advantage that the direction is automatically changed to a direction in which the cleaning effect is excellent without damaging the gums. As a result, the user does not have to change the rotational direction of the toothbrush head by operating a separate operation button as in the conventional art, which is convenient and safe, and also improves the cleaning efficiency.
