Description

PLASMA WIND FAN}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plasma-type air blower capable of blowing air into a space to sterilize a space, or to treat human bodies such as skin.

Plasma has been regarded as a technology that takes the lead in semiconductor manufacturing. Recently, a lot of researches have been conducted on fusion technology that applies plasma for biological use. Various plasma generating apparatuses are being developed to obtain the effect of treating the human body with plasma to treat skin diseases, promote hair growth, or sterilize air or objects. In such a bio-plasma application, conventional plasma adopts a method of directly contacting a glow plasma emitting light to an object surface or skin. That is, conventional plasma devices are a method of directly irradiating a plasma beam or a plasma plume to a skin or a device. In this case, the length of the plasma or the diameter of the irradiation is several millimeters. Therefore, there is a space limitation in their use. There is an inconvenience that these devices should be used close to the skin or the surface, and when a large area is to be treated, there is a time limit because the plasma having a small irradiation diameter needs to be moved while being moved.

 Korean Patent No. 10-1292268 also proposes a plasma treatment apparatus. However, since the plasma generation source itself must be fixed to the structure and the affected part must be exposed to the plasma at the time of long treatment, the problem of self-use is also difficult.

Korean Patent Application No. 10-2010-0097961 proposes an air purification apparatus using plasma, but no specific plasma generation apparatus and power source are described.

Korean Patent Application No. 10-2011-008094 proposes a hair dryer that emits a plasma, but a heater is replaced by a plasma generating device without a device for generating hot air, and a power generating device for generating plasma is shown at 7 kV, It is inconvenient to use it because it is not built in and is provided separately on the outside. Above all, the structure of the electrode for generating plasma is not described at all, and therefore, the apparatus can not be used in practical use.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the disadvantages and limitations encountered in the processing due to the narrow emission region of plasma, and to provide a plasma wind blower capable of exhibiting the effect of plasma processing in a large space.

According to the above object, the present invention relates to a plasma treatment method and apparatus for cleaning a plasma by discharging electrons, ions, and various radicals (electrons + ions + various radicals) constituting the plasma to the surface of hair, skin or object, or chemically reacting with pathogens in the air, A plasma-blowing blower is provided which causes the plasma-blower to function.

Further, the present invention provides a plasma hair dryer or a skin disease treatment apparatus by adding a heater to the plasma wind blower.

The plasma wind blower described above is configured such that a discharge port through which air is blown out from the blowing fan is narrowly provided from the body and an electrode for generating plasma is provided inside the outlet port of the discharge port. The electrode for generating plasma is a tungsten needle electrode having a high voltage electrode and a grounding electrode provided thereon, a syringe needle tube electrode having a needle electrode as a high voltage electrode and a ground electrode as a hole in a flat plate Method, or a DBD (Dielectric Barrier Discharge) method.

The heater is preferably installed between the fan and the electrode.

The plasma wind blower of the present invention can be composed of a housing similar to the appearance of a general hair dryer.

Conventional plasma treatment apparatuses generate plasmas in a state in which the length and diameter of a plasma column are limited to a few millimeters. Therefore, in order to sterilize skin, hair, and equipment, a plasma plume of a small diameter Or beam) of the plasma, it is difficult to treat the plasma for a long time. However, when the plasma wind blower of the present invention is used, plasma particles (electron + ion + various radicals) can be brought into contact with a large area, It is advantageous.

That is, the present invention does not directly bring the plasma plume or the beam itself into contact with the object to be processed. However, taking into consideration that the life time of particles of the plasma is several tens of microseconds to several tens of microseconds, Glow) type plasma, but a considerable number of plasma particles are converted into plasma wind. Plasma winds have several tens of centimeters of irradiation length and space, so that desired effects such as sterilization, disinfection, and treatment can be obtained for a wide space.

According to the present invention, the plasma particles are contacted with the skin to activate the skin tissue, sterilize the skin to maintain cleanliness, and have a therapeutic effect through activation of skin cells. In order to maximize the therapeutic effect, medicines such as ointment can be used together. These medicines facilitate penetration into the skin by the plasma, thus enhancing the therapeutic effect.

Further, by adding a heater to the plasma wind blower of the present invention, it is the same as using a plasma hot air dryer, and when a hair dryer is used for wet hair drying or hairdressing, have. In addition to this, it is possible to obtain the effect of preventing and treating skin beauty and skin diseases by irradiating plasma wind to general skin.

Also, since the plasma wind blower of the present invention provides a dedicated power source device having a DC-AC inverter, it can be used as a general household power source, can be used as a separate DC power source battery, It can be used as a portable plasma device, so that it is convenient to perform operation without any place.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

1 shows a basic configuration of a plasma wind blower. And shows a basic form of a plasma-blower equipped with a fan and a handle composed of a plasma generating device. Fig. 1 (a) is a schematic cross-sectional view showing a schematic structure of a plasma-blower, and Fig. 1 (b) is a perspective view showing the appearance of a hair dryer. The fan that drives the wind is driven by the motor. To this end, the fan blades 200 coupled to the motor 100 are assembled into a housing, such as a hair dryer. Inside the handle 300, a fan-motor (which means a module composed of a motor 100 and a fan blade 200 coupled thereto) and a power supply device 400 for driving the plasma generating device are incorporated.

The configuration of the plasma generator of such a plasma wind blower is described in detail in FIG. 2 and FIG.

Plasma generation basically uses DC or low frequency alternating current to discharge the atmosphere. Generally, a DC-AC inverter with a frequency of several tens Hz to several tens of kHz is used. In addition, plasma may be generated by discharging the atmosphere itself by high frequency RF and / or microwave discharge using a semiconductor oscillation element.

The rotation speed of the fan-motor and the amount of generated plasma are controlled by a drive switch 600 provided on the handle.

The plasma discharge port 800 is installed narrowly and long from the fan-equipped body to quickly maintain the speed of the wind. It is a feature of the present invention that a plasma generating apparatus is provided inside the outlet of the discharge port 800 in the plasma blowing apparatus. When the plasma generator is installed in the body space, the plasma particles easily lose energy and become neutralized in the inner space of the body. Therefore, it is preferable to install the plasma generator at the narrow outlet side in order to maximize the energy of the plasma particles.

The working principle is that the plasma generated in the discharge port 800 is discharged by the fan through the discharge port in the form of wind in the form of plasma particles (electrons + ions + various radicals).

The amount of plasma particles generated by the atmospheric discharge can be controlled by controlling the voltage applied to the electrode and the plasma current.

The generation of wind can be performed by an air compression method by a compressor other than a fan-motor.

FIG. 2 illustrates a method in which electrodes are provided on the inner surface of the plasma discharge port. Plasma generation can be done in a variety of ways, and FIGS. 2 and 3 illustrate some examples of plasma source structures for a plasma wind blower.

2 (a) shows an electrode configuration of a direct discharge plasma generation method. And the plasma electrode 500 is provided at four places on the inner surface of the discharge port. The electrodes are preferably arranged in a radial direction.

The annular ground electrode 520 is fixed with the tungsten needle 510 fixed to the inner surface of the discharge port of the housing and with a slight gap d (1 to 10 mm, but not limited to) at the tip of the needle. A high voltage is applied to the tungsten needle 510 and the annular ground electrode 520 is grounded to generate plasma between the tungsten needle 510 and the annular ground electrode 520. The diameter of the tungsten is several millimeters (may be from 1 to 10 mm, but is not limited) and is acuminate with a sharp tip. The power through the inverter is applied to the tungsten pin 510 through the safety capacitor C _B. The distance d between the end of the tungsten needle 510 and the ground electrode 520 is preferably about 1 mm. A voltage of 1 to 3 kV having a frequency of several tens kHz is applied to the tungsten needle 510 to cause a discharge between the tip of the tungsten needle 510 and the ground electrode 520 to generate a high density glow plasma. These plasmas come out of the discharge port by plasma winds by the fans inside the housing. The tungsten needles 510 may be deformed to four or more when arranged radially. In addition to tungsten, the needle electrode may be made of a discharge-resistant alloy or platinum, titanium, or the like.

2 (b) shows application of a plasma source of a dielectric barrier discharge method using a dielectric such as a glass plate. And the plasma generator is installed at four places on the inner surface of the discharge port. A metal electrode 530 is provided on the lower surface of the dielectric 535 made of a glass or quartz and a ground electrode 540 is provided on the upper surface of the dielectric 535 in the longitudinal direction. The metal electrode as the high voltage electrode is arranged to face the discharge port wall surface. In this embodiment, a glass plate is used, a ground electrode 540 is grounded, and a power is applied to the metal electrode 530 to generate a dielectric barrier discharge in the vicinity of the ground wire. The thickness of the dielectric 535 is preferably about 1 mm, and the voltage applied to the metal electrode 530 is 1 to 3 kV at several tens of kHz.

FIG. 3 shows an electrode installation method configured to pass through the inner end surface of the plasma discharge port.

3 (a), a direct discharge type plasma source using a syringe needle electrode 550 is applied. A syringe needle electrode 550 is provided at four places in the body of the discharge port and a plate-shaped ground electrode 560 having a hole at the end of the needle electrode 550 is disposed. That is, a body 555 filled with an insulator is disposed in such a manner as to penetrate the needle electrode 550, and the needle electrode 550 is disposed at a position spaced about 1 mm from the end of the needle electrode 550, (Four holes as a whole) plate-like ground electrode 560 (hole of the ground electrode is positioned so as to be aligned with each other so as to communicate with the hole of the needle electrode of the syringe, Which means that the ground electrode is positioned further forward than the outlet of the needle electrode electrode). Plasma is generated between the tip of the needle electrode 550 having an inner diameter of several mm or less and the ground electrode 560 plate. To this end, a voltage of 1 to 3 kV, typically tens of kHz, is applied to the needle electrode 550 of the syringe. The syringe needle electrode 550 and the hole of the ground electrode plate may be modified to four or less.

FIG. 3 (b) shows application of a dielectric barrier discharge plasma source employing a dielectric 575 such as a glass plate or a quartz plate. 2 (b), two plate-shaped dielectrics 575 having a slit shape are provided on the end of the discharge port, and a high-voltage electrode plate 570 is formed on the back surface of each dielectric 575 And a ground electrode plate 580 is installed in a space such as a slit which is a space formed by the front surface of the dielectric 575. A voltage of 1 to 3 kV, typically tens of kHz, is applied to the high voltage electrode plate 570 to generate a dielectric barrier discharge type plasma.

4 is a sectional view of a plasma-type blower in the form of a hair dryer in which a heater 700 is installed. A heater coil is provided between the fan and the plasma discharge port. Here, the plasma generation method is similar to the example of FIG. 2 and FIG. In addition to a heater coil (which means a resistance wire coil), a hot air device using a magnetron (high frequency heater) may be formed. The installation of the heater also controls the emission of plasma particle species. This is because the amount of specific plasma particles such as ozone varies greatly depending on the ambient temperature. This problem can be achieved through experimentation and the adjustment function can be installed on the device as needed.

The plasma hair dryer shown in Fig. 4 is provided with a switch terminal for controlling a hair dryer function that only emits hot air, a plasma wind function that does not operate the heater but a plasma wind only, and a plasma wind You can make it.
