Abstract

PURPOSE: A rotating toothbrush which is cheap unlike the conventional electromotive toothbrush, can prevent the tooth from damaging, and can clean the tooth effectively by the repeated rotating rubbing of the circle-shaped brushes due to the sliding of a pulling pipe is provided. CONSTITUTION: The rotating toothbrush is characterized by being comprised of: a circle-shaped board(8) planted on a brush(7), fixed to one side of an axis(5) which is installed at the front part of the inside holder and a belt(3); a spring which one tip is connected to the belt(3) and the other tip is to a stopper(11); a pulling pipe(12) with a flange(12'), inserting the holder; and a pin(14) penetrated a long hole(13) inside the holder, which front tip is connected to the belt(3).

Description

Spin toothbrush

The present invention relates to a rotating toothbrush. Conventional techniques in which a toothbrush rotates include its own patent application No. 35041 (brush rotating device of a toothbrush) in 1998 and an electric toothbrush powered by an electric motor. In addition, a simple conventional toothbrush that does not rotate the brush has a problem in that the toothbrushing efficiency is unreasonable from a dental perspective, so that teeth are not evenly wiped to every corner and tooth damage is promoted. And electric toothbrushes have the disadvantage of being too expensive.

The present invention has been made to solve the drawbacks of the prior art as described above, it does not require a battery or charging as a conventional electric toothbrush, and makes the production cost cheaper and at the tooth surface as in the conventional method of using a manual toothbrush. When rubbing the brush and letting the pull back reciprocating slightly in the toothbrush bar, the brush planted in the disc causes the reciprocating frictional action on the tooth surface to provide dentally reasonable tooth damage prevention effect.

The present invention provides a brush (1) through a hole (6 ') of a stopper (6) on one shaft (5) of a belt (3) wheel (4) attached to the distal end of the hollow part (2) of the toothbrush stand (1). 7) Insert the disk 8 into the insert tube 9 so that the disk 8 can be inserted and detached, and a belt (9) is provided in the handle tube 9 in which one end of the toothbrush stand 1 is loosened. 3) The other end of the spring 10 to which one end is connected is connected to the end of the closed tube 11, and one end of the pull pipe 12 inserted into the toothbrush rod 1 is provided with acupressure ( 안내) A flange (12 ') or a mouthpiece flange (12 ") for circumferential support is formed in a circular shape, and the guide hole installed in the toothbrush stand (1) in the middle of the pull tube (12). The pin 14 is fixed so as to penetrate 13 and penetrates through the end hole of the belt 3 in the hollow portion 2. In the embodiment of the present invention, the area of the disk 8 brush 7 is too large. When it is small, the ordinary brush (7 ') is planted in a flat plate that can be attached to and removed from the aide. Figure but may.

Referring to the operation of the present invention configured as described above are as follows. To clean the teeth, first hold the handle tube (9) and clean the tooth surface like a conventional toothbrush while pulling the acupressure flange (12 ') of the pull tube (12) with your thumb. Observation 11 connected to the other end of the belt 3 while the front end of the fixing pin 14 sliding in the long hole 13 attracts one end of the belt 3 wound on the wheel 4 in the hollow part 2. The belt 3 is pulled to the opposite side due to its elasticity as the spring 10 is automatically retracted when the negative spring 10 is stretched and the flange 12 'is left unattended.

Accordingly, the wheel 4 on which the belt 3 is wound reciprocates, and the brush 7 of the disc 8 inserted and inserted into this shaft 5 repeats the reciprocating rotational friction on the tooth surface. And when the toothbrush is damaged, only the brush 7 disc 8 can be replaced. Therefore, it shows the effect of preventing tooth decay by removing debris with economical and dental reasonably brushing action.

In addition, the present invention is superior in utility because it is simple in structure, hassle-free in the use of electric power, and is inexpensive compared with the conventional electric toothbrush.

As described above, in the present invention, when the fixing pin 14 of the pull tube 12 inserted into the toothbrush rod 1 performs the reciprocating sliding action in the guide hole 13, the fixing pin 14 extended to the hollow part 2. Since the belt 3 attached to the tip is pulled left and right, the reciprocating rotational movement of the wheel 4 becomes possible. Tooth decay occurs mainly in the molar teeth, even if the thumb pressure (指 押) (12) by pressing the (押 壓) to remove the debris of the molar well. In the first half of the molar, incisor, etc., the mouth pressure flange 12 "of the pull tube 12 is applied to the periphery of the mouth, and only the handle tube 9 is used for a simple retreat movement like a normal toothbrush. 3) The wheel 4 automatically repeats the reciprocation rotation, and therefore, the formation of the shiatsu flange 12 'is omitted.

In this way, the toothbrush stand 1 is provided with a finger pressure flange 12 ′ as shown in FIG. 1 and a mouth pressure flange 12 ″ supporting the peripheral portion as shown in FIG. 4. Since it is formed separately, it is possible to manufacture as convenient, and when the brush 7 of the toothbrush stand 1 is small, the brush 7 'is planted on an elongated flat plate which is detachable. It is also economical because it can be replaced, and it combines the linear reciprocating friction action of the ordinary brush 7 'and the rotational friction action of the disc 8 brush 7. Effect.

Unlike the linear reciprocating frictional action of the conventional toothbrush, the present invention is provided by sliding the pulling tube 12 formed of the same body by simply pushing the acupressure flange 12 'or the old pressure flange 12 "around the finger or mouth. The disk 8 brush 7 facing the tooth surface repeats reciprocating rotational friction, which not only wipes every corner of the tooth evenly but also provides excellent dental protection against dental damage and is significantly cheaper than conventional electric toothbrushes. It is practical.
