Abstract

The present invention relates to an electric toothbrush that is driven by a rechargeable battery as a power source. To date, the products of the toothbrush movement method are simple movements in one method (swing method or bus method or other method) determined at the time of manufacture. It was researched and invented to work in a compound motion method. In other words, the general electric toothbrush is made to operate the toothbrush simply by changing the direction of movement in a predetermined manner using a single motor. To explain in detail, until now, since the movement method of the electric toothbrush has used a single motor, the brush head has only one simple movement such as moving from side to side, up and down, swinging or swinging with the electric toothbrush body as the axis. It was designed and built to be.

However, the present invention knows that such a powered toothbrush has not been completely cleaned inside the oral cavity and complete cleaning of the teeth, but after food meals remain around the teeth after the meal is entangled to form a stone-like hard tartar In order to solve this problem, digital technology, which can be called the flower of modern scientific civilization, is applied to electric toothbrush and researched to make movement of toothbrush part of electric toothbrush into vertical, left, right and right movement.

In other words, the present invention is to place the motor to move the axis of the electric toothbrush left and right in the middle of the body portion (also called the handle portion) and the electronic vertical movement vibrator placed on the same shaft By combining the two movements, the brush movements resulted in a complex movement. In other words, two instruments such as a motor and an electronic vibrator are combined to interlock on the same axis.

In addition, these movements are connected to digital electronics to supply electricity to voltage regulators and inverters to adjust motor rotation speed in multiple stages or to adjust vibration speed of electronic vibrators, which is the most suitable complex movement for the mouth and teeth of electric toothbrush users. It is a state-of-the-art electric toothbrush that allows users to select and use their own method and to know the state of charge and discharge of the battery and the current state of the compound movement by installing a digital display.

Description

Digital complex move Electric Toothbrush

The present invention relates to an electric toothbrush that operates by using a rechargeable battery as a power source. In order to improve the toothbrush movement method, an electric vibrator is installed on the same shaft in addition to a conventional motor mounting method. Equipped with a toothbrush movement up, down, left and right, it can be more helpful for oral hygiene and teeth cleaning. Until now, electric toothbrushes used only one motor as a driving mechanism.

The present invention is a new technology that allows the toothbrush of the electric toothbrush to perform a complex movement with two drive mechanisms, such as a motor having a reciprocating mechanism and an electronic vibrator.

For the cleanliness of the mouth and long-term preservation of the teeth, it is ideal to give little food residue in the mouth after eating. However, it is difficult to clean it with a regular toothbrush or remove it completely with existing commercial electric toothbrushes. These existing toothbrushes are simple in their way of movement and cannot completely remove food debris between teeth. Therefore, the study of the toothbrush to clean even a little better is the toothbrush compound movement method of the present invention.

(A) (b) of the present invention is a side view and a front view of the electric toothbrush of the present invention and the permanent magnet (9) on the shaft (2) connected to the toothbrush (1) in FIG. It is mounted in the middle of the vibrator coil 7. Such a mechanism is not present in electric toothbrushes to date and was first applied in the present invention. In the electric toothbrush to date, the movement method of the toothbrush consists of simple movements, such as [Fig. 6], [Fig. 6-1], left and right movements, [Fig. 6-2] vertical movements, and [Fig. 6-3] swing movements. . This is because there is only one driving motor. 6-4 is a toothbrush operation of the present invention shows that the movement up, down, left and right. The bristle movement of the left and right movements ranges from 1 to 3 mm, the movement speed is between 5,000 to 10,000 rpm, and the up and down movements corresponds to sound waves with the bristle amplitude of approximately 0.1 to 1.0 mm and the vibration speed of 15,000 to 35,000 stroke / min. Therefore, the present invention is an invention that can realize a sound wave vibration-type electric toothbrush at the same time.

According to the present invention, the survival of human beings is improved, and the advancement of the disease is well prevented and cured due to the advancement of medicine and science. Since it is deodorized and cannot chew foods, it is difficult to digest and taste bad, so it is unfortunate to live an unhealthy life. To maintain dryness until the time of death, a toothbrush that can best protect the health of the teeth and the hygiene of the oral cavity is most effective. The study led to the conclusion that the combined exercise toothbrush was the most effective. In order to solve this problem, it is best to brush by compound movement, but general brushing by hand is impossible, and only the electric toothbrush is possible to perform complex movements.

The present invention is a combination of a digital electronic circuit to the electric toothbrush built-in left and right movement method of the conventional technology of the past and the electronic vibrator having a frequency belonging to the sound wave is mounted on the axis of the electric toothbrush in conjunction with the left and right movement of the toothbrush The exercise was invented to operate in the left and right and up and down combined movement.

In addition, the display is equipped with the movement of the movement and the charge and discharge status of the rechargeable battery can be seen. Command and execution of all these operations were solved by MCU.

In the present invention, the long-term preservation of the tooth was how to wipe cleanly between the gums and teeth and teeth, that is, triangular delta area to eliminate food waste. The result is the most ideal and effective brushing because the brush is selected from the left and right movements and the upper and lower vibrations are added to the brush, which is the best brushing practice recommended by dentists. have. Since such a compound exercise is a result of pounding the gums at the same time as a gum massage effect, the present invention is an electric toothbrush that achieves the most suitable effect for human dental health.

The present invention will be described in detail with reference to the accompanying drawings.
