Abstract

The present invention is a manual toothbrush that can make brushing more convenient, clean, and quicker by rotating bristles in a vertical direction about a single rotational axis by means of a gear action by grip.

Description

Vertical rotating hand operated tooth brush

The present invention relates to a manual toothbrush in which the bristles rotate in a vertical direction by means of a gear action caused by a grip force, and is a manual toothbrush designed to allow a user to easily and quickly clean teeth between teeth.

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

However, in general,'stick type general toothbrush','horizontal rotation type electric toothbrush','vertical rotation type two rotation axis electric toothbrush', etc. are inconvenient to use, difficult to clean between teeth, or are large in size and complicated in structure, so production cost is high. There are problems such as a lot and difficult to commercialize.

First of all, the'general stick toothbrush' has a problem that is inconvenient to use and takes a lot of time because the hand moves to brush your teeth.

In the'horizontal rotating electric toothbrush', it is difficult to clean the teeth between the teeth such as the molar teeth because the direction of rotation of the bristles is kept horizontal with the teeth.

'Vertical rotation type 2 rotary shaft electric toothbrush' is inconvenient to use due to its complicated structure, high production cost, and bulky.

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.

Since 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.

And because it is a manual toothbrush in which the bristles rotate in the vertical direction by gear action by grip force, it is eco-friendly and has low production cost, so it has price competitiveness.

Since the structure is simple and production costs are reduced, the possibility of commercialization is very high, and not only the general public, but also 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 is again composed of 1. oral guard, 2. bristles, 3. rotating shaft, and 4. connector.
On the outside of the body, there are 5. rotation direction selection buttons and 6. a hand lever connected to the inner gear.
Inside the body part, it is composed of 7. rotation shaft, 8. rotation direction selection gear box, and 9. power transmission gear device.

In [Fig. 1], when the user presses '6. a hand lever', the internal gear rotates and the rotation shaft starts to rotate.

The user can select the rotation direction of the bristles by using the '5. rotation direction selection button'.

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 teeth using this.

'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. rotation direction gearbox' is a device that controls the rotation direction of the rotation shaft.

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

'3. Rotation Shaft' in [Fig. 1] and '7. Rotation Shaft' in [Fig. 3] are devices that are connected to each other and encompass a separate type and an integral type.

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.

In [Fig. 3], when the user presses the '6. hand lever', the internal gear rotates and the power is transmitted to the rotating shaft, and the rotating shaft rotates.

The symbols used in this specification are generally used symbols.

Claims (6)

The present invention is a manual toothbrush that rotates the bristles of a toothbrush in a vertical direction by a single rotation axis. The method according to claim 1, wherein the bristles are planted on a rotation shaft, and the rotation shaft rotates in a vertical direction to rotate the bristles. The method according to claim 2, wherein when the bristles rotate, an oral protector is installed for the safety of the skin inside the user's mouth, and the oral protector covers the bristles, and the part where the bristles contact the teeth is open. The oral protector according to claim 3 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 this rotation shaft is connected to the rotation axis of the gearbox in the rotation direction inside the toothbrush body. . The rotation direction gearbox of claim 4 is a device capable of selecting a rotation direction based on a gear principle. The toothbrush body has a rotation direction selection button and a hand lever, and this handle is connected to a gear device inside the body, so that the rotation shaft is rotated by a gear action by a grip force.
