【発明の詳細な説明】 この発明は歯槽膿漏等の歯部疾患を、電気を流
すことによつて治療し予防する、電気歯ブラシに
関するものである。
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric toothbrush that treats and prevents dental diseases such as alveolar pyorrhea by passing electricity through the toothbrush.

歯槽膿漏の治療に歯科医師用で、患者が手に持ち
先端を患部に当てて使用する電気治療器がある
が、この原理は本発明歯ブラシと同様のものであ

められているものである。
There is an electric therapy device used by dentists to treat alveolar pyorrhea, which the patient holds in their hand and applies the tip to the affected area.The principle of this device is the same as that of the toothbrush of the present invention, and electricity is passed to the affected area. Its therapeutic effects have already been recognized.

しかしこの治療は長期に続ける必要があるので
一般の人は通院が困難となり、大切な歯を抜かね
ばならなくなつてしまう場合が多かつた。
However, since this treatment had to be continued over a long period of time, it was difficult for the average person to go to the hospital, and important teeth often had to be extracted.

従来この治療器の原理を歯ブラシに応用したも
のが市販されたことがあつた。
In the past, a toothbrush that applied the principle of this treatment device was commercially available.

This toothbrush has a dry battery housed inside its handle, a current-carrying element in contact with one electrode exposed in the grip, and a front electrical path exposed from the other electrode to the tip of the brush. During use, the current-carrying element in the grip comes into contact with the hand, and a circuit is formed between the human body and the moisture in the mouth between the electric circuit exposed in the front part of the brush part, thereby sterilizing teeth, gums, and the inside of the oral cavity. It has the effect of promoting blood circulation to the gums, etc., and giving vitality.

ものである。
However, with this conventional toothbrush, the toothbrush remains wet after use, and when it is placed in a toothbrush holder,
Since the brush part at the tip is forced to face upward, the moisture contained in the brush drips onto the handle and wets the current-carrying element in the grip, so this moisture forms a circuit that connects the exposed part of the front electrical circuit and the current-carrying object. The battery will be consumed until the water is completely dry.
The short lifespan of dry cell batteries made them uneconomical, and the highly effective electric toothbrushes were unpopular, and production was finally discontinued, dooming them to disappear from the market.

The inventor himself was suffering from alveolar pyorrhea and was happy to see that it was effective after using this electric toothbrush. I had been using it for a long time, but I was very disappointed that it was discontinued, so I researched various ways to make dry batteries last longer, and as a result, I completed the present invention.

Reference numeral 9 denotes a press-fitting part, which is made of a thin and elastic material that bulges out to cover the opening of a space 10 provided in a part of the handle 1 that avoids the current-carrying body 4, and is dented by grip force. A cylindrical switch movable body 6a with a connection 12 of the front electric circuit 5a exposed on the inner surface of the cylindrical hole is attached to the inside of this press-fitting part 9, and a switch movable body 6a is provided protruding into a space 10 in the handle 1. The cylindrical switch fixing body 6b is inserted into the cylindrical hole of the switch movable body 6a, and a power supply side front electric circuit 5b in contact with the (+) pole of the DC power supply 2 is provided on the outer periphery of the switch fixing body 6b. several stages of parallel contacts 13 connected to
This parallel contact 13 is exposed at a position opposite to the contact 12 of the front electric circuit 5a on the distal end side, and when not in use, a spring 11 fitted to the outer periphery of the switch movable body 6a is press-fitted. The part 9 protrudes outward and bulges, and thus the second
When the press-fitting part 9 bulges out as shown in the figure, the front electric circuit 5b on the distal end side is disconnected by the switch device 6, and when the press-fitting part 9 is depressed by the grip force during use, the switch movable body 6a is activated by the spring. 11 is pressed and pushed in, the contact 12 is lowered, and the parallel contact 1
3, the front electric circuit 5 is connected or disconnected when it comes into contact with or separates from any one of them.

With the above-described configuration, the present invention has the front electric circuit 5 disconnected when not in use, but when in use, by squeezing the handle 1, the press-fitting part 9 is pressed and recessed, so the front electric circuit is disconnected by the switch device 6. It will turn on or off depending on the strength, and when the switch device 6 is turned on, the exposed part will be transferred from the hand touching the current carrying body 4 to the tip-side front electric circuit 5a via saliva and moisture in the arm and mouth. An electric circuit will be formed from 7 to the power source, and since the grip force on the handle changes constantly while brushing teeth, this electric circuit will be turned on and off repeatedly by the switch device 6. .

Therefore, electricity is repeatedly connected and disconnected to the teeth and gums, and at the moment electricity is connected, a large current flows and can give strong stimulation to the teeth and gums, so it is necessary to repeatedly turn on and off in this way. This method has a greater effect on treating problems such as alveolar pyorrhea than the conventional method of continuously applying electricity, and the prevention and treatment of dental diseases can be done naturally every time you brush your teeth. can keep the body healthy.

そして不使用時には、たとえ歯ブラシが濡れて
いても内部で前部電路5が切れているから、電気
回路は形成されず直流電源2が消耗することは無
くなる。
When the toothbrush is not in use, even if the toothbrush is wet, the front electric circuit 5 is cut off internally, so no electric circuit is formed and the DC power source 2 is not consumed.

直流電源2の耐用時間が24時間の乾電池を使用
するとして、従来あつたものは水濡れ放電のため
2〜3日しか使えなかつたが本案によれば、 24×60分=1440分の耐用で、1回の歯磨時間を
平均3分間とすれば、 1440÷3=480すなわち、1本の乾電池で480回
使用できることとなり、1日1回の歯磨きなら1
年と4ヶ月近く使用できるし、1日2回使用して
も7ヶ月近く使用できるので乾電池の消耗は極め
て僅かなものとなる。
Assuming that the DC power supply 2 uses a dry cell battery with a lifespan of 24 hours, conventional batteries could only be used for 2 to 3 days due to discharge due to water exposure, but according to this proposal, the lifespan would be 24 x 60 minutes = 1440 minutes. If the average time per tooth brushing is 3 minutes, then 1440 ÷ 3 = 480, that is, one dry battery can be used 480 times, and if you brush your teeth once a day, it will take 1
It can be used for nearly 4 months per year, and even if used twice a day, it can be used for nearly 7 months, so the battery consumption is extremely small.

なお、本案品は直流の低電圧であるから、実際
使用時に痛みも何も感じることがないので、乾電
池が消耗しているかどうかはわからないものであ
る。
Furthermore, since this product uses low DC voltage, you won't feel any pain during actual use, so you won't know if the dry cell battery is exhausted or not.

そこで第3図に示すような検電器とケースを兼
用した検電ケース14を使用すると便利である。
Therefore, it is convenient to use a voltage detection case 14 that serves both as a voltage detector and a case as shown in FIG.

This voltage detection case 14 includes contact parts 15 and 16 where the current-carrying body 4 and the exposed part 7 at the tip of the brush part come into contact when the electric toothbrush is inserted with the brush part 7 facing downward, and a pilot lamp 17 is interposed between them. Since the voltage detection path 18 is configured as shown in FIG. It's easy to know.

また、先端のブラシ部分は、図示は省略してあ

As stated above, this invention eliminates the drawbacks of conventional electric toothbrushes, completely prevents wasteful consumption of power, is economical for long-term use, and is easy to use. Electricity flows intermittently in response to changes in grip strength, which further strengthens the stimulation and strengthens the sterilizing power.It has a therapeutic effect comparable to that of a dentist's treatment, and a preventive effect that can be achieved through daily routine actions. It is possible to provide an extremely excellent electric toothbrush that is obtained naturally and has a wonderful effect of protecting dental health, which is a problem for all humankind, and brings great good news to many people with poor teeth.
