Abstract
Description
The present invention relates to an electric toothbrush for brushing teeth while rotating the brush using electricity, and more particularly, it is possible to simultaneously clean the front and rear surfaces of the tooth by providing two cylindrical brushes rotated by a drive motor. At the same time, the brush movement direction is moved from top to bottom for upper teeth and from top to bottom for lower teeth, which not only cleans every corner of rugged teeth, but also shortens brushing time and It relates to an electric toothbrush that further improves the convenience of brushing teeth, such as less effort.
Electric toothbrushes are toothbrushes that rotate or vibrate with an electric force to clean teeth. Originally developed for use by people who cannot use their hands well, such as disabled people and children, it is also used by the general public because of the convenience of not having to use a lot of hands.
In general, the toothbrush moves in order to brush the upper teeth from the top to the bottom, and the lower teeth from the bottom to the top, so that every corner of the tooth can be wiped clean and the gums are healthy. However, the conventional electric toothbrush has a problem that can be wiped every corner of the tooth because the brush is to rotate in the tooth surface irrespective of the direction of the tooth.
In order to solve this problem, as shown in Figure 1, the
The electric toothbrush puts the battery inside through the
The electric toothbrush is a cylindrical brush for cleaning the teeth 12 rotates from above to below or below to the direction of the teeth, so as to clean not only the protruding inner or outer surfaces of the teeth, but also the gap between the teeth and the teeth. It has an effect.
However, the electric toothbrush of the above-described application has a problem in that it takes a lot of time to brush the teeth and takes a lot of arm strength because it needs to clean the front and rear of the tooth separately.
Modern people are living in busy daily life, and especially in the morning, because of the tendency to run out of time due to commute or school time, the reduction of brushing time is convenient for modern people.
The present invention has been made to solve the problems of the conventional electric toothbrush as described above, the present invention allows the cylindrical brush to clean the front and rear of the teeth at the same time to shorten the brushing time and accordingly less arm force It is an object of the present invention to provide an electric toothbrush that further improves the convenience of brushing teeth.
Electric toothbrush of the present invention for achieving the above object is a handle in which a drive motor and a battery is built-in, a cylindrical brush mounting portion having a lower cover formed on the front end as coupled to the handle, the rotary cover on the lower cover of the cylindrical brush mounting In the powered toothbrush which is installed as possible and includes a cylindrical brush driven by a drive motor installed inside the handle, two cylindrical brushes are rotatably installed on the lower cover of the cylindrical brush fitting, and the two cylindrical brushes are toothed. Spaced apart from each other by an interval corresponding to the thickness; A power transmission device is configured between the output shaft of the drive motor and the two cylindrical brushes.
The powered toothbrush of the present invention is also characterized in that the two cylindrical brushes of the power train are adapted to rotate in opposite directions.
The electric toothbrush of the present invention is also connected to the shaft of the drive motor and an extension shaft having a power transmission protrusion formed at the output end, which is installed in the cylindrical brush installation port and coupled to the power transmission protrusion of the extension shaft. And a power splitting means for dividing and transmitting the power output from the input shaft into two cylindrical brushes.
The electric toothbrush of the present invention is also configured inside the cylindrical brush fitting which the power dividing means is shielded by a central blocking plate and a side through tube, and is engaged with the drive gear provided in front of the input shaft and the drive gear. A driven gear, two flexible shafts respectively connected to the drive gear and the driven gear, and two flexible shafts connected to each other and installed at the rear of the two cylindrical brushes to rotate the cylindrical brush. It is characterized in that it comprises a column (gear 列).
The electric toothbrush according to the present invention can cleanly clean even the gap between the protruding portions of the teeth by rotating the cylindrical brush in direct contact with the teeth and rotating from above to below or below to the direction of the teeth. Since the cylindrical brush cleans the front and back of the teeth at the same time, the time required to brush teeth is cut in half, thus reducing the effort to brush the teeth, improving the convenience of use and keeping the teeth cleaner and healthier.
