DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for easily and cleanly brushing dentures.

[0002]

2. Description of the Related Art As an apparatus for removing denture stains, an ultrasonic cleaning apparatus can be used. In this device, dentures are immersed in water or a cleaning solution of a dentifrice case, and water or the like is ultrasonically vibrated to remove dirt attached to the surface. When this device is used to clean dentures, it is difficult to completely remove dirt attached to the surface. In principle, the output of the ultrasonic waves can be increased to cleanly remove dirt. However, when the ultrasonic output is increased, there is a disadvantage that extremely unpleasant noise is generated. Also, the equipment becomes extremely expensive. This is because an electric circuit that generates ultrasonic waves and an element that converts an electric signal into ultrasonic vibrations become expensive. Therefore, it is not actually possible to increase the ultrasonic output so much as a denture brushing device used at home.

[0003] Detergents that dissolve in water to produce bubbles and a cleaning solution without using ultrasonic waves have also been developed. The method of using the cleaning agent is to soak the dentures in water contained in a container, and to wash by putting the cleaning agent in water. The cleaning agent dissolves and drains the cleaning solution, and the water is stirred with foam to wash the dentures. This method is more difficult to clean dentures than ultrasound.

[0004]

Therefore, the method using a cleaning agent and the method using an ultrasonic cleaner cannot clean the dentures as if they were brushed with a toothbrush. Dentures
You can remove it and brush it with a toothbrush. However, since the dentures that have been removed are not fixed to the mouth, it is difficult to hold them with one hand and brush with a toothbrush held in another hand. . This is because, when brushing with a toothbrush, the dentures move and it is difficult to maintain a posture that is easy to brush.

[0005] The method using an electric toothbrush can easily brush dentures as compared with a normal toothbrush.
This is because the toothbrush is electrically vibrated, so that dentures can be brushed without violently moving the toothbrush. However, this method also has the disadvantage that not everyone can brush their teeth simply and easily, just like ordinary teeth. In particular, many elderly people are not good at using dentures to dexterously move their hands. For this reason, if it takes time or is difficult to brush your teeth,
There is a disadvantage that it cannot be used conveniently.

The present invention has been developed to solve this drawback. It is an important object of the present invention to provide a denture brushing device that allows anyone to easily and easily brush a denture.

[0007]

By rotating both ends of the brush 2, the brush 2 can be rotated more smoothly. However, the brush can be rotated by driving one end of the core wire.

As shown in FIG. 10, the drive mechanism 3 rotates the inner brush 2b and the outer brush 2c in the directions indicated by arrows. The lower brush 2a can be rotated in the same direction as the outer brush 2c or in the same direction as the inner brush 2b.

The drive mechanism 3 is a mechanism that is built into watertight drive 8 consists of a mechanism that is incorporated in the main body 6, the dentifrice case 1 in a state of being mounted on the main body 6, the driving mechanism 3 of the body 6 watertight The rotation shaft 10 is rotated by being connected to the drive mechanism 3 of the drive unit 8.

The drive mechanism 3 of the watertight drive unit 8 has a drive shaft 12 connected via a gear to a rotating shaft 10 connecting the inner brush 2b and the outer brush 2c. The drive shaft 12 has a drive gear 13 fixed at the center. The drive gear 13 is connected to the output gear 17 of the drive mechanism housing 6B with the toothpaste case 1 set in the main body 6. The drive shaft 12 and the rotary shaft 10 are connected by a small gear 14 fixed to the drive shaft 12 and a bevel gear 15 meshing with the small gear 14. As shown in FIG. 11, the rotating shaft 10 connecting the lower brush 2a is connected to the rotating shaft 10 of the inner brush 2b via a spur gear 16, and is opposite to the inner brush 2b, that is, in the same direction as the outer brush 2c. Is rotated.

The drive mechanism 3 built in the main body 6 connects an output gear 17 to an output shaft of a motor 18 via a gear. In the drive mechanism 3, the motor 18 rotates the output gear 17 via a gear, and the output gear 17
And the drive shaft 12 rotates the rotary shaft 10 to rotate the brush 2.

As described above, the U-shaped groove 9 is provided by the three U-curved brushes 2, the dentures 4 are set therein, and the tooth brushing device is used. Can be held in place by the brush 2 and polished neatly. However, the denture brushing device of the present invention does not specify the shape of the brush 2 and the driving mechanism 3 of the brush 2 in the above-described structure.

As shown in FIGS. 12 and 13, the brush 2 may be a combination of a U-curved brush and a linear brush. 12 is an inner brush 2b.
And the outer brush 2c are U-shaped brushes, and the lower brush 2a
Has a structure in which a plurality of linear brushes are arranged. This brush 2 can polish the upper surface of the denture with the U-curved inner brush 2b and the outer brush 2c, and polish the lower surface of the denture with the linear lower brush 2a in a state in which the toothpaste case 1 is filled with water or a cleaning liquid. . The lower brush 2a brushes the lower surface of the denture with a plurality of straight brushes. Furthermore, the brush 2 of FIG. 13 uses the lower surface brush 2a as a U-shaped brush,
The inner brush 2b and the outer brush 2c are linear brushes. The upper surface of the denture is brushed by the inner brush 2b and the outer brush 2c, and the lower surface of the denture is brushed by the lower brush 2a.
