Description

Plasma generation device with ozone emission prevention function}

The present invention relates to a plasma generating apparatus having an ozone emission prevention function.

More specifically, a plasma module including a housing having an internal space, an electrode part seated in the housing, a supply path for supplying an inert gas to the electrode part, and a suction path through which external air is sucked, and a supply amount of the inert gas A control box including a gas supply unit that regulates and supplies to the supply path, a power supply unit that applies voltage to the electrode unit, a pump connected to the suction path to suck in the external air, and a filter unit that removes ozone contained in the sucked external air Including, the control box is characterized in that operated in one of a first mode for generating plasma by injecting an inert gas according to a selection mode, and a second mode for generating atmospheric plasma and operating a pump and a filter unit, It relates to a plasma generating device having an ozone emission prevention function.

In general, an atmospheric pressure plasma generator used for plasma treatment of skin and biological tissues generates plasma by applying a voltage to an electrode and activates a gas to be injected to perform a surface treatment process.

Such a plasma generating device is used for skin and biological tissues, and can have selective killing of biological tissues, blood coagulation and hemostasis, sterilization, skin irritation and regeneration effects, and is used as a medical treatment and skin beauty device.

Looking at the conventional technology using plasma, a portable beauty device using plasma (Korean Utility Model Registration No. 20-0454538) has a technology to eradicate bacteria adhering to the face or skin using a light-thin carbonized plasma. In addition, the plasma skin regeneration device (Korean Patent No. 10-1262632) has a technology that can be used for skin treatment by generating glow plasma.

Plasma generators used for such medical/skin cosmetic applications are required to secure safety and stability in direct plasma irradiation to the human body. However, prior literatures do not disclose an alternative to ozone generated when plasma is generated.

When plasma is generated, ozone, which is harmful to the human body, is generated together with beneficial ions. Ozone causes corneal inflammation, pulmonary swelling, skin disease and respiratory disease upon prolonged exposure. Accordingly, it is necessary to remove ozone generated when plasma is generated.

In addition, plasma has a therapeutic effect for each function (sterilization, regeneration, elasticity, etc.) depending on the output voltage, but there is a risk of skin burns due to heat generation. In this regard, in the related art, heat generation has been reduced by adjusting the plasma duty.

However, if the conventional duty control method is applied, it is possible to obtain effects such as sterilization and regeneration only when a large amount of output time is required due to low power. In the conventional duty control method, functional effects such as skin regeneration and elasticity improvement are inevitably reduced. Accordingly, there is a need for another method for preventing burns caused by heat generation when plasma is generated.

Referring to FIG. 1, the plasma generating apparatus may be composed of a plasma module 100 and a control box 200 in which plasma is generated, and as shown in FIG. 2, the gas cylinder 300 can be detached and used according to the user's mode selection. have.

Meanwhile, the shape of the plasma generating device of FIG. 1 is an example, and may be modified in various forms. For example, when the gas cylinder 300 is not mounted, it may be implemented in the form of a plasma module 100 including a control box to facilitate portability.

Referring to FIG. 2, the plasma module 100 may include a housing 110 including a head 111, a supply path 120, a suction path 130, and an electrode unit 140. In this case, the electrode unit 140 may be an electrode that generates a dielectric barrier discharge plasma. In addition, the control box 200 may include a power supply unit 210, a gas supply unit 220, a pump 230, and a filter unit 240.

The housing 110 may include an inner space and a head 111. In this case, the electrode unit 140 may be seated in the internal space, and a supply path 120 for supplying an inert gas to the electrode unit 140 and a suction path 130 for sucking external air may be formed.

In this case, the supply path 120 may be formed such that one side is connected to the gas supply unit 220 of the control box 200 and the other side extends toward the head 111 of the housing 110. The supply path 120 receives the inert gas from the gas cylinder 300 mounted on the control box 200 according to the adjustment of the gas supply unit 220 and provides a path to move to the electrode unit 140 seated in the internal space. I can.

In addition, one side of the suction path 130 may be connected to the pump 230 of the control box 200 and the other side may extend toward the head 111 of the housing 100. The suction path 130 may provide a path to move to the pump 230 by sucking the external gas of the head 111.

The electrode unit 140 may generate plasma when a voltage is applied from the power supply unit 210. At this time, the electrode unit 140 may generate a dielectric barrier discharge (Dielectic Barrier Discharge) plasma, and the plasma source may be an inert gas or atmospheric gas supplied through the supply path 120, and the user's mode selection Can be selected according to.

The power supply unit 210 of the control box 200 may apply a voltage corresponding to the user's selection mode input through the input panel to the electrode unit 140.

The plasma generating apparatus of the present invention may operate in one of a first mode in which plasma is generated by injecting an inert gas, and in a second mode in which atmospheric plasma is generated and the pump 230 and the filter unit 240 are operated. In addition, each mode may be divided into detailed modes that provide different functions (sterilization, skin regeneration, elasticity improvement, skin hygroscopicity increase, etc.) depending on the amount of gas and a preset voltage.

For example, the first mode may include a skin regeneration mode and an elasticity improvement mode, and the second mode may include a skin sterilization mode and a moisturizing effect mode.

The gas supply unit 220 is driven when operating in the first mode, receives an inert gas from the mounted gas cylinder 300, and supplies it to the supply path 120 by adjusting the amount of gas supplied according to the detailed mode of the first mode. can do. In this case, the inert gas may be moved through the supply path 120 and supplied to the electrode unit 140.

Here, the inert gas may be helium, argon, neon, chromium, xenon, or the like. However, argon is preferable in terms of cost. The inert gas may be provided through the head 111 in a plasma state in response to a voltage applied to the electrode unit 140. At this time, the inert gas does not generate ozone gas during ionization. Accordingly, ozone generation can be blocked at the source.

At this time, the gas cylinder 300 is detached from the gas supply unit 220, and the gas supply unit 220 can inject the inert gas only in the first mode. In the second mode, a voltage is applied from the power supply unit 210 to the electrode unit 140 without supply of an inert gas, and when ozone is generated by atmospheric plasma discharge, the pump 230 sucks ozone through the suction path 130. Thus, it can be moved to the filter 240.

3 is a view for explaining gas supply and suction through the head of FIGS. 1 and 2. Referring to (a) of FIG. 3, the head 111 of the plasma module 100 is formed on one side of the housing 100, a gas moving hole 10 is formed in the center, and the gas moving hole 10 is centered. As a radial lattice protrusion 11 may be formed. The radial grating protrusion 11 may form a supply passage through which the radiated plasma is supplied while forming a gap with the skin. At this time, the protrusion 11 is formed in a radial shape so that the plasma can be uniformly distributed.

At this time, as shown in (b) of FIG. 3, plasma is supplied to the skin through the gas movement hole 10 when operating in the first mode, and external air is sucked through the gas movement hole 10 when operating in the second mode. Can be.

In this way, the gas movement hole 10 is used as a common hole for supplying plasma or inhaling external air, thereby increasing the effective area of the plasma outside the head 111, and cooling effect when supplying plasma or inhaling external air It can be generated and prevent the skin temperature from rising.

The filter unit 240 may be provided with a filter 241 having activated carbon (C) therein, and a means for extending a movement path of ozone passing through the filter 241. Through this, it is possible to increase the filter performance by prolonging the time for the ozone to react with the activated carbon.

If there is no means for extending the movement path of ozone, ozone moves the filter 241 in a certain path (straight forward) and reacts with the activated carbon. Although the length of the filter 241 can be extended to extend the path, this has a disadvantage in that air resistance is increased. Accordingly, in the present invention, the reaction can be maximized by extending the movement path of ozone through vibration, rotation, etc. without extending the length of the filter 241.

At this time, the ozone (O ₃ ) passing through the filter 241 may vertically move in a direction perpendicular to the longitudinal direction of the filter 241 by a magnetic field, and a movement path may be generated in the fluid flow direction (the longitudinal direction of the filter). . Accordingly, it is possible to extend the reaction time by generating a moving path that is longer than a path that goes straight in the longitudinal direction of the filter.

In addition, according to another embodiment of FIG. 5, the filter unit 240 may include a filter 241 having activated carbon (C) therein, and a vibration means 243 for providing vibration to the filter 241. .

At this time, the ozone (O ₃ ) passing through the filter 241 may vertically move as in the embodiment of FIG. 4 by the vibrating motion of the filter 241 to generate a movement path. Accordingly, it is possible to extend the reaction time by generating a moving path that is longer than a path that goes straight in the longitudinal direction of the filter.

Further, according to another embodiment of FIG. 6, the filter unit 240 may include a filter 241 having activated carbon (C) therein, and a rotating means 244 for rotating the filter 241.

At this time, ozone (O ₃ ) passing through the filter 241 may generate a moving path that spirally moves along the inner diameter of the filter 241 as shown in FIG. 6 by centrifugal force according to the rotational motion of the filter 241. Accordingly, it is possible to extend the reaction time by generating a moving path that is longer than a path that goes straight in the longitudinal direction of the filter.

As shown in FIGS. 4 to 6, filter performance can be improved by extending the reaction time by extending the movement path of ozone reacted in the filter 241. The filter 241 may be equipped with activated carbon (C) to discharge carbon dioxide when reacting with ozone.

As a result, when the plasma generating device is used, ozone can be prevented from the source through the first mode using an inert gas, or side effects caused by ozone generated during atmospheric plasma discharge in the second mode can be prevented. Accordingly, it is possible to protect the skin from ozone while selecting a mode according to the user's purpose.

On the other hand, what has been described with reference to FIGS. 1 to 6 above is a description of only the main matters of the present invention, and the present invention is limited to the configuration of FIGS. 1 to 6 as various designs are possible within the technical scope.
