The vertical rotating type electric toothbrush of the present invention has a very high possibility of success in commercialization by having a simple structure and reduced production costs.

Description

Vertical rotating electronic tooth brush

The present invention relates to an electric toothbrush in which the bristles are rotated in a vertical direction by an electric motor, and is an electric toothbrush designed to allow a user to easily and quickly wipe teeth between teeth.

Most dentists around the world recommend brushing your teeth vertically as the correct way to use a toothbrush.

However, in general, types of toothbrushes include'bar-type general toothbrush','horizontal rotation type electric toothbrush','vertical rotation type two rotation shaft electric toothbrush', and the like. Toothbrushes of this type have problems such as inconvenient use, difficult to clean between teeth, large size and complex structure, high production cost and difficult commercialization.

First of all, the'general rod-shaped toothbrush' is inconvenient to use and takes a lot of time to brush teeth because it is brushed by moving the hand.

In addition, the'horizontal rotating electric toothbrush' maintains the direction of rotation of the bristles horizontally with the teeth, so it is difficult to clean between teeth, and the lower part of the bristles has an articulated gear device, so there is a risk of tooth damage due to severe vibration.

In addition, the'vertical rotation type 2 rotary shaft electric toothbrush' has a complicated structure, high production cost, and bulky, making it inconvenient to use.

In the present invention, by rotating the bristles vertically by a single axis of rotation, it is possible to clean and easily wipe between teeth.

Because it is a single rotating shaft, the structure is simple, so production cost is reduced, productivity is high, and it is easy to commercialize because of its price competitiveness.

In addition, children, the elderly, patients, and the disabled can easily and cleanly brush their teeth.

Since the structure is simple and production costs are reduced, there is a very high possibility of success in commercialization, and children, the elderly, patients, and the disabled can greatly contribute to maintaining dental health.

The present invention is largely composed of a head and a body of an electric toothbrush.
The head again consists of 1. oral guard, 2. bristles, 3. rotating shaft, and 4. connector
There are 5. rotation direction selection button and 6. power button on the outside of the body part, and inside the body part is composed of 7. rotation axis, 8. rotation direction control gearbox, 9. electric motor, and 10. battery

In [Fig. 1], when the user presses the '6. power button', power is supplied to the electric motor from the battery and the electric motor starts to operate.

The user can select the rotation direction of the bristles by using the '5. rotation direction selection button', and the rotation direction selection button controls the gearbox inside the body.

There is a passage inside the '4. connector' so that the rotating shaft rotates in it.

When the '3. rotating shaft' rotates, the '2. bristle' planted at the end of the rotating shaft rotates, and the user brushes their teeth using this.

'5. Rotation direction selection button' is a concept that encompasses both manual and electronic types.

'1. Oral protector' serves to protect the skin inside the user's mouth, and can be manufactured in various designs.

In [Fig. 3], the '8. gearbox' is a device that controls the direction of rotation of a rotating shaft, and is a concept encompassing both manual and electronic types.

'10. Dry cell' is a concept that encompasses both removable and non-removable, rechargeable and non-rechargeable types.

The toothbrush head and the toothbrush body cover both separate and integral types.

'3. Rotation Shaft' in [Fig. 1] and '7. Rotation Shaft' in [Fig. 3] are also concepts encompassing both separate and integral types.

The vertical rotation direction refers to the direction in which the bristles rotate from top to bottom or from bottom to top when the toothbrush is viewed horizontally from the user's perspective.

The symbols used in this specification are generally used symbols.

Claims (7)

A vertically rotating electric toothbrush is an electric toothbrush that rotates the bristles of a toothbrush in a vertical direction by a single rotation axis. In Paragraph 1 above, the bristles are planted on a rotating shaft, and the rotating shaft rotates in a vertical direction to rotate the bristles. When the brush head rotates, an oral protector is installed to protect the skin inside the user's mouth. The oral protector covers the brush head, and the part where the brush head contacts the teeth is open. In paragraph 3 above, the oral protector is connected to the toothbrush body by a connection pipe, and there is a passage inside the connection pipe, so that the rotation shaft enters the passage, and in the above paragraph 2, the rotation axis is connected to the rotation axis of the gearbox inside the toothbrush body. Has been. The gearbox in Clause 4 above is a device that can select the direction of rotation by the gear principle. The gearbox includes both manual operation and automatic operation. The toothbrush body has a rotation direction selection button and a power button. The power button is a device that operates the device by connecting or disconnecting electricity from the electric toothbrush.
