Abstract

The present invention relates to a brush rotating device of a toothbrush. Conventional manual toothbrushes are problematic because they linearly reciprocate the brush on the tooth surface, and in particular, molar teeth and the like are difficult to clean. Electric toothbrushes have the disadvantage of being too expensive to charge as well as being too expensive.

The present invention has been devised to solve the above-mentioned drawbacks. Just by rubbing the tooth surface with a brush like a conventional toothbrush, the internal toothbrush rod 2 and the tube 12 are relatively stretched by relative stretching action. The rack 16 reciprocates the pinion 4 and the belt wheels 3 and 7 also interlock to cause the brush 10 disc 11 to reciprocate. In the process of rubbing the tooth surface, it shows a rational tooth cleaning effect because it has a complex friction action that combines a linear reciprocating motion and a reciprocating rotational motion.

Description

Brush rotator of toothbrush

The present invention relates to an apparatus for rotating a brush of a toothbrush. Tooth brushing method includes a manual method of reciprocating the toothbrush by hand and an electric method of brushing the tooth by vibrating or rotating the toothbrush with an electric motor. Among the conventional manual toothbrushes, the toothbrush is linearly reciprocated from the tooth surface. Because of repeated friction only, there is a problem from the dentist's point of view and molar teeth are not easily wiped, the electric toothbrush has the disadvantage of changing or recharging the battery frequently, too expensive.

The present invention has been devised to eliminate the drawbacks of the prior art as described above, and does not require batteries or charging like conventional electric toothbrushes, and is inexpensive to produce, and the brush on the tooth surface according to the conventional toothbrush usage method. Just rub) into the reciprocating motion along with the linear reciprocating motion to clean every corner of the teeth.

The central shaft 5 of the pinion 4 formed in the same body as the belt wheel 3 is mounted on the right inner wall of the toothbrush stand 2 on which the hollow part 1 is formed, and the fixed shaft 6 formed on the opposite inner wall. The central hole (9) is inserted into the sedan insert (8) so that one sedan insert (8) of the belt wheel (7) boss (7 ') is exposed out of the toothbrush holder (2). (8) is inserted into a small disk (11) in which a large number of brushes (10) are detachable, and a pipe (12) inserted into the other end of the toothbrush pole (12). Pin 14, which is fixed to the toothbrush pole 2, is inserted into the long hole 13 installed in the main body 13, and a weak spring 15 is inserted into the inner wall of the head 12 'of the pipe 12. The long rack 16 is fixed to engage the pinion 4 through the hole of the washer 17 at the end of the hollow toothbrush rod 2, and the pull 18 in the middle of the toothbrush rod 2 It was made by the establishment of.

In the drawings, reference numeral 19 denotes a belt.

Referring to the operation of the present invention configured as described above are as follows.

A fixed shaft 6 formed on the left inner hollow inner wall by rotating the central shaft 5 of the pinion 4 made of the same body as the belt wheel 3 on the hollow inner wall on the right side of the toothbrush rod 2 on which the hollow part 1 is formed. ), The center hole 9 of the belt wheel 7 boss 7 'formed in the same manner as the sedan insert 8 of the toothbrush stand 2 is inserted. When the belt 횔 3 rotates, the belt wheel 7 rotates via the V-belt 19, and the disc 10 of the brush 10, which is inserted into the sedan insert 8 outside the toothbrush rod 2, also rotates together. do. And when holding the duct (12) loosely fitted to the toothbrush pole (2) and rub the tooth from side to side with the brush (10), due to the frictional resistance between the tooth and the brush (10) the duct 12 is The weak spring 15 is impeded by the pin 14 embedded in the toothbrush pole 2 at the time of contraction by the length of the long hole 13 cut from the toothbrush rod 2 to the collecting pipe 12 against the elasticity of the weak spring 15. On the other hand, the long rack 16 fixed to the inner wall of the pipe 12 head 12 'causes the engaged pinion 4 to reciprocate and at the same time the belt wheel 3 formed of the same body also reciprocates. This rotational force is transmitted to the belt wheel 7 through the V-belt 19 so that the reciprocating rotational movement is carried out, so that the sedan insert 8 outside the toothbrush pole 2, which is an extension of the boss 7 ', is also inserted therein. The brush 10 is to repeat the reciprocating rotation with the disk 11. Therefore, holding the pipe (12), rub the tooth in the same way as the conventional toothbrush use, the toothbrush pole (2) and the pipe (12) is relatively stretched by the elastic spring 15, the brush 10 is the tooth surface In the complex reciprocating type that combines the linear reciprocating motion and the rotary reciprocating motion, the tooth debris is effectively removed. This is due to the fact that the rack 16 fixed to the inner wall of the collecting tube 12 head 12 'is engaged with the pinion 4 through the hole of the washer 17 on the toothbrush 2 end. The reciprocating rotational movement of the pinion 4 is enabled with the expansion and contraction.

On the other hand, in the corners such as molar where the brush 10 does not enter well, the mutual extension and movement of the toothbrush pole 2 and the collecting pipe 12 is strengthened only by pulling the pull 19 with a finger and thus, the brush 10 disk. The reciprocating rotation of (11) is assured.

In carrying out the present invention, instead of omitting the tug 19, a single layer which can be pulled freely in any direction may be rounded off.

The present invention, unlike the conventional manual toothbrush, and holding the pipe (執 管) (12) and rub the teeth in the same way as the conventional toothbrush, brush 10 of the disc 11 in a straight direction from the tooth surface (齒 面) At the same time, the tooth is cleaned better than the conventional one because the movement is performed simultaneously with the left and right rotational reciprocating movements, and the reciprocating reciprocation of the brush 10 is continued when the pulley 18 is used at the limit point where entry of the toothbrush such as molars is blocked. .
