Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a so-called electrodeless discharge tube used for beauty health, particularly a beauty health discharge tube that emits near-infrared rays, and a beauty treatment using the same. The present invention relates to a discharge device for health.

[Conventional technology]

The present inventor has decided to adopt an electrodeless structure as a discharge tube for facial health, with the aim of suggesting that the interior of the glass container is colored by discharge and suggests a beautiful facial health effect, because the radiant energy is small and it is difficult to generate heat. For example, a structure in which a discharge electrode is not provided inside a glass container and a conductive terminal is arranged on an outer peripheral portion of the container, and a high-frequency voltage is applied to the terminal to generate a discharge inside the container has been previously proposed. This is because the glass container is filled with nitrogen gas after high vacuum processing, 330 nm
It has a structure capable of emitting ultraviolet light having a wavelength of about 400 nm, and is a relatively small one that is directly applied to the face, shoulders, waist, etc., and is used to promote beauty health.

[Problems to be solved by the invention]

However, since the previously proposed structure is an electrodeless structure, the impurity gas adsorbed and occluded in the glass container is evacuated and evacuated while being baked out, and then nitrogen gas is sealed, and then this is chip-off. The glass container is contaminated by the impure gas such as carbon dioxide gas generated from the glass container due to the high heat generated when the chip is turned off, and the color tone at the time of discharge is blurred and red or red is not obtained. Has a problem that it is difficult to obtain.
In addition, because of the electrodeless discharge type, the discharge starting voltage becomes extremely high, and if the continuous use time is not limited in relation to the withstand voltage of the transformer, the power supply circuit may be heated,
It became clear that the noise was too loud to ignore. In addition, the high-voltage discharge gives a strong stimulus to the body and may be considered dangerous.

The purpose of the present invention is to be able to stably emit near-infrared rays, which have the action of activating the skin and promoting metabolism, in red or red indicating a thermal effect, and
An object of the present invention is to provide a discharge lamp for beauty and health with an electrodeless structure that does not give a high-voltage stimulus that is considered dangerous. Still another object of the present invention is to provide a relatively small facial health discharge device that contributes to the promotion of facial beauty by directly applying to the face or shoulders using the above-mentioned electrodeless discharge tube for facial health. It is in.

[Means for solving the problem]

As a means for solving the above-mentioned problems, the beauty health discharge tube according to the present invention is a barium metal adhered by heating a barium getter on the inner peripheral surface at one end side of a glass container which is filled with neon gas and hermetically sealed. A structure having a film and having conductive terminals disposed on the outer peripheral surface side of the glass container near the same portion is employed.

In order to increase the concentration or directivity of the discharge generated inside the glass container by the application of a high-frequency voltage as described later in operation, a narrow portion is formed at the base end of the glass container,
Preferably, the barium metal film is formed near the constriction.

In order to configure a discharge device for facial health using such a discharge tube, the base end of the glass container is attached to an insulating casing also serving as a handle, and the casing includes a high-frequency voltage generating circuit, thereby generating a voltage. The high frequency voltage to be applied may be applied to the conductive terminal.

[Action]

According to the above means, the tip of the glass container is face,
When a high-frequency voltage is applied to the conductive terminal by directly touching the shoulder, waist, etc., the barium metal film adhered to the inner peripheral surface of the glass container absorbs the high-frequency voltage from the metal terminal through the dielectric glass and emits electrons. , Facilitates the onset of radiation. This makes it possible to reduce the voltage applied to the conductive terminals, reduce the noise level and the heat generation of the power supply circuit, increase the stable operation by continuous use, and not to give a dangerous high voltage stimulation. Act on. Because the barium getter absorbs the impure gas inside the glass container and increases the degree of vacuum,
The color generated by the ionization of the neon gas due to the discharge becomes clear red or red, and near infrared rays are stably emitted.

When the barium metal film is formed on the inner peripheral surface of the constricted portion of the glass container base end, the direction of electrons emitted from the barium metal film is concentrated with directivity by the constricted portion, with a so-called hollow effect, It works to further reduce the discharge starting voltage.

〔Example〕

FIG. 1 shows a discharge tube 1 for health care according to one embodiment of the present invention.

The discharge tube 1 shown in FIG. 1 has a substantially spherical distal end portion, a relatively elongated shape, and a dielectric transparent glass container 2 having a constricted portion 2A at a base end portion thereof, which is filled with pure neon gas to form a high vacuum. A barium metal film 3 formed by flashing a barium getter is adhered on the inner peripheral surface of the constricted portion 2A at the base end, and a metallic conductive terminal 4 is disposed on the outer peripheral portion of the constricted portion 2A. Is arranged.

The pure neon gas is filled after the impurity gas adsorbed and occluded in the glass container 2 is evacuated and evacuated while baking out to a high vacuum, for example, several torr to several tens torr.

The barium getter for generating the barium metal film 3 is, for example, BaAl ₄ and is included in the barium getter by being activated or flushed in a high-frequency heating furnace or the like after being filled with pure neon gas and hermetically sealed. The barium metal film 3 is attached to the inner peripheral surface near the constricted portion 2A. The barium metal film 3 not only functions to absorb the impure gas generated by the discharge and keep the neon gas at a high purity, but also has an electron emission function for starting the discharge.

FIG. 2 shows an embodiment of a beauty health discharge device using the beauty health discharge tube 1 described above. In the discharge device 5, a base end of the discharge tube 1 is mounted on a casing 6 which also serves as a handle formed of an insulator such as a resin, and a high-frequency voltage generation circuit 7 and a power supply circuit 8 for driving the discharge tube 1 to discharge. Built-in. The high-frequency voltage generation circuit 7 includes:
For example, an oscillation transformer that oscillates when excited by a transistor inverter that receives a DC voltage of several volts,
It outputs a high-frequency voltage of about 00 volts (about 20 to 50 KHz).

When a high-frequency voltage is applied to the conductive terminal 4 while the glass container 2 of the discharge tube 1 for beauty and health is brought close to or directly applied to the face, shoulders, waist, etc., an uneven electric field is formed and a creeping corona glow on the inner surface of the glass container 2 (Creepage glow corona) or creepage corona is about to occur, but the barium metal film 3 applied to the inner peripheral surface of the glass container 2 absorbs a high-frequency voltage from the metal terminal 4 through the dielectric glass and emits electrons, Facilitates the start of discharge. Therefore, the high-frequency applied voltage to the conductive terminal 4 can be reduced, thereby suppressing the noise level and the heat generation of the power supply circuit, guaranteeing the continuous stable operation, and the high voltage of the dangerous Will not give irritation. Since the barium getter absorbs the impure gas and increases the degree of vacuum inside the glass container 2, the color generated by the ionization of the neon gas due to the discharge becomes a clear red or red color and the near infrared rays are stably emitted. . At this time, since the high-frequency voltage is lower than before and the neon gas is filled, the ozone odor is minute.

In this way, the near-infrared ray radiated through the glass container 2 raises the temperature of the skin surface and its shallow layer by several degrees, for example, from about 3 ° C. to about 10 ° C., thereby promoting cell activation and metabolism, which is a beautiful face. Contribute to health promotion.

In particular, since the barium metal film 3 is formed on the inner peripheral surface of the constriction 2A at the base end of the glass container 2, the direction of electrons emitted from the barium metal film 3 has directivity due to the constriction 2A. With a so-called hollow effect,
The discharge starting voltage can be further reduced.

 Next, an experimental example will be described.

The discharge tube 1 for facial beauty used in the experiment had a total length of 145 mm, a maximum diameter of the tip of 25 mm, and a high frequency applied voltage of about 2,000.
The operation is performed under the conditions of volts and an oscillation frequency of about 32 KHz, and an example of the output spectrum characteristics of the discharge tube 1 obtained thereby is shown in FIG. According to this, from 700nm to 1090n
Near infrared rays having a wavelength of m can be obtained at about 10 to 15%.

Although the invention made by the present inventors has been specifically described based on the embodiments, it is needless to say that the present invention is not limited thereto and can be variously modified without departing from the gist thereof.

For example, in the above embodiment, the emphasis is only on near-infrared radiation, but this does not prevent the possibility of emitting ultraviolet components including a small amount of nitrogen gas. Further, the glass container may be colored red or red, which is limited to transparent glass. Further, the transistor inverter of the high-frequency voltage generating circuit is not limited to a bush-pull type including an inductance and a resonance circuit in series with a DC power supply, and various other circuit configurations can be adopted.

[Effect of the invention]

The discharge tube for facial beauty according to the present invention has a barium metal film adhered to the inner peripheral surface on one end side of the discharge tube having an electrodeless structure. This film absorbs a high frequency voltage from the metal terminal through the dielectric glass. And emits electrons to facilitate the start of discharge.

Therefore, it is possible to reduce the high-frequency applied voltage to the conductive terminal, thereby suppressing the noise level and the heat generation of the power supply circuit, guaranteeing the continuous stable operation, and stimulating the high voltage that is considered dangerous. Not be given.

In particular, by forming a barium metal film on the inner peripheral surface of the constriction at the base end of the glass container, the constriction concentrates the direction of electrons emitted from the barium metal film with directivity, further reducing the firing voltage. Can be done.

In addition, since the barium getter absorbs the impure gas and increases the degree of vacuum inside the glass container, the color generated by the ionization of the neon gas due to the discharge becomes a clear red or red color and stably emits near infrared rays. There is an effect that can be. At this time, the high-frequency voltage is made lower than before and the filling gas is neon gas, so that the ozone odor is very small.

The near-infrared light radiated through the glass container in this manner causes the skin surface and its shallow layer to reach several degrees, for example, from 3 ° C.
The temperature rises by about 10 ° C. to promote cell activation and metabolism, which contributes to the promotion of beauty and health.

In addition, since the skin or the like can be used close to or in contact with the surface of the glass container, the use efficiency of the radiated near-infrared rays can be improved, and the waste of energy can be suppressed.
