Install) to connect both toothbrush fixing panels (17) to each other,

In the gear portion 27 formed on the center outer circumferential surface of the screw rod 24, the coupling hole 25 is formed with a guide hole 26 to insert the rack gear portion 23 and the carriage 21 provided with the handle 22 ) Is installed.

7 is a partially enlarged cross-sectional view of a state in which the electric toothbrush of the present invention is configured separately;

The toothbrush drive shaft 8 and the circular toothbrush drive shafts 7 on both sides are separately formed, and inserting holes 29 are formed in the drive shafts 8 and 7 on one side to be inserted and detached from each other.

8 is an enlarged perspective view showing a toothbrush installed in the electric toothbrush of the present invention;

A plurality of toothbrushes 13 are formed in a rectangular cross section, and a plurality of bristles are installed on one side, and a plurality of inclined surfaces 30 are formed at both ends of a surface where the bristles are installed, and the bristles are installed in an inclined manner.

The operation of the present invention will be described below.

When brushing teeth using the electric toothbrush of the present invention, as shown in FIG. 9, both molar teeth are inserted into the recesses 18 formed in the toothbrush fixing panels 17 on both sides, and the entire tooth is a plurality of toothbrushes 13. The toothbrush mounting portion 2 is held in the mouth as if the mouthpiece is positioned therebetween, and then a power is supplied to the motor 5 by operating a switch (not shown) installed in the handle case 4.

When power is applied to the motor 5, the toothed gear drive shaft 8 and the circular toothbrush drive shaft 7 connected thereto rotate while the spur gears 6 in the driving unit 1 connected to the rotary shaft of the motor 5 rotate.

As the circular toothbrush driving shaft 7 on both sides rotates, the upper and lower surfaces of the molars are wiped by rotating the circular toothbrush 14 positioned between the molars on both sides.

As the toothbrush driving shaft 8 in the center rotates, the worm gear 15 of the power transmission unit 3 is rotated in one direction, and the worm gears 15 'and 15 "connected to both sides rotate simultaneously, and the spring 10 is rotated. Inner, outer and upper, lower toothbrush 13 is connected to be rotated at the same time.

At this time, the toothbrush 13 installed on the upper and lower sides rotates the bristles toward the upper side in the case of the upper teeth, and in the case of the lower teeth, sets the rotation direction of the motor 5 so that the bristles rotate from the lower side to the upper side. You can protect and clean your teeth more cleanly.

In the electric toothbrush of the present invention, the fixed frame 12 constituting the toothbrush mounting portion 2 is connected by a plurality of hinge connecting portions 9, and a plurality of toothbrushes 13 and circular toothbrushes 14 installed therein are springs ( 10), it is possible to transfer the rotational force of the motor 5 to the toothbrush 13 and the circular toothbrush 14 by the flexibility and elasticity of the spring 10 as it is, the shape according to the user's teeth Can be used to deform, it is possible to protect the mouth guide by blocking the fixing frame 12 is connected to the flesh in the mouth when the toothbrush 13 rotates.

The support 11 installed on both inner sides of the fixing frame 12 is to prevent the toothbrush 13 from flowing during use by firmly supporting the outer toothbrush 13 without disturbing the rotation.

The long hole 19 to which the outer toothbrush 13 of the toothbrush fixing panel 17 is coupled allows the toothbrush 13 to slide along the long hole 19 when the outer toothbrush 13 rotates outside the tooth, thereby fixing the toothbrush. It is possible to minimize the size of the electric toothbrush because it does not have to form a space required for rotation of the toothbrush 13 on the outside of the panel 17.

In more detail, when the bristle is rotated to face inward, the toothbrush 13 is moved outward of the long hole 19 by the tension force of the spring 10, and when the bristle faces outward, the fixing frame 12 The toothbrush 13 is pushed inward while being in contact with the side surface, so that the toothbrush 13 rotates along the long hole 19.

A plurality of worm gears 15, 15 ′, 15 ″ connected to the toothbrush drive shaft 8 connected to the drive unit 1 to rotate the toothbrush 13 are installed in the protective case 16 to install the worm gears 15, 15. ') (15 ") to prevent injuries to the mouth that can occur during rotation.

On the other hand, as shown in Figures 5 to 6 by installing the gap adjusting means on the toothbrush fixing panel 17 on both sides it can be easily removed without inserting the toothbrush mounting portion (2) in the mouth without forcibly opening the mouth.

Looking at the operation of such a gap adjusting means, when the width of the toothbrush mounting portion (2) widen or squeeze the handle 22 connected to the carriage 21 by hand to push or pull, it is connected to the coupler (25) The rack gear portion 23 is moved together while the carriage 21 inserted into the guide hole 26 of the side is moved to one side, and the rack gear portion 23 and the gear portion 27 are engaged with each other. The screw rod 24 is rotated while being inserted into the screw hole 28 of the gap adjusting hole 20 installed in the toothbrush fixing panel 17 to adjust the distance of both toothbrush fixing panel 17.

In addition, as shown in FIG. 7, the central toothbrush drive shaft 8 and the circular toothbrush drive shafts 7 on both sides are separately formed to be detached by the insertion hole 29, thereby making it easy to store and carry the electric toothbrush. will be.

On the other hand, the plurality of toothbrushes 13 used in the present invention, as described above, by installing a plurality of inclined surfaces 30 at both ends of the surface where the bristles are installed, thereby installing the bristles in an inclined state, when the toothbrush 13 rotates Complementing the gap formed between the toothbrush 13 and the toothbrush 13 is to clean all the parts of the tooth that could not be cleaned by the conventional manual toothbrush or electric toothbrush.

As described above, the present invention includes a plurality of toothbrushes rotated by a motor and rotates in the state of the door like a mouthpiece so that all teeth can be polished at the same time. It can be wiped cleanly to areas that do not, and it is more convenient to use, which can greatly contribute to maintaining the health of teeth.
