Description

{Portable Plasma skin care Apparatus}

The present invention relates to a cosmetic device, and more particularly to a portable plasma cosmetic device.

The lowest energy state of matter is solid. The solid is energized gradually to become liquid, then to the gas. At this time, sufficient energy above the ionization energy is applied to the neutral gas, and ionization and recombination of electrons and ions can generate plasmas composed of electrons, ions, neutral atoms and molecules.

Inside the plasma, positive ions (ions) and negative charges (electrons) are mixed in almost the same amount, and they are called electrically electrically ionized conductive gas paper because they maintain neutrality electrically while performing Brownian motion close to free particles.

Plasma has several criteria such as plasma density, electron temperature, degree of thermal equilibrium between species, generation method and application field, but it is most basic to classify it into density and electron temperature.

The local heat equilibrium (LTE) and the non-local thermal equilibrium (non-LTE) can be divided into the plasma by the degree of thermal equilibrium, and the term local heat equilibrium means that the temperature of all of the plasma particles is The same thermodynamic state in the local region.

Plasma for research and manufacturing processes is usually one of LTE or non-LTE plasma, and the electron is generally called thermal plasma and the latter is called low-temperature plasma.

For skin beauty, mainly low-temperature plasma is targeted, and atmospheric plasma is used in low-temperature plasma.

An inert gas is mainly injected from the outside and a high voltage is applied to the needle electrode structure to generate plasma. A dielectric barrier discharge (DBD) type plasma jet device having a small hole at the center of a small circular parallel plate has been introduced.

1 is a configuration diagram of a portable plasma beauty apparatus 10 according to an embodiment of the present invention.

The portable plasma aesthetic device 10 according to the present embodiment includes only a simple configuration for clearly explaining the technical idea to be proposed.

1, the portable plasma aesthetic apparatus 10 includes a power supply electrode 101 and a ground electrode 102, a gas supply unit 110, a power supply unit 120, A vibration sensor 160, a skin condition sensor 170, a wireless communication module 180, and a camera 190. The wireless communication module 180 includes a wireless communication module 130, an auxiliary head 140, a velocity sensor 150, a vibration sensor 160, .

The detailed configuration and main operation of the portable plasma beauty apparatus 10 configured as above will be described below.

The main body is made of a plastic insulator and includes a power supply electrode 101 and a ground electrode 102, a gas supply unit 110, a power supply unit 120, a speed sensing sensor 150, A skin condition detection sensor 170, a wireless communication module 180, and a camera 190. The skin condition detection sensor 170,

The body may be generally cylindrical and the surface of the body may be easily gripped by the user with one hand and rubber material may be additionally attached to prevent slippage.

The gas supply unit 110 supplies gas around the power supply electrode 101 inside the main body.

The gas supply unit 110 is configured to supply at least one of argon, helium, general air, nitrogen, hydrogen, and oxygen to the power supply electrode 101.

First, as a first embodiment of the gas supply unit 110, the gas supply unit 110 may be configured to include a first gas cartridge, a second gas cartridge, and a mixing unit.

The first gas cartridge contains a carrier gas of argon or helium, and the second gas cartridge contains a reaction gas of air, hydrogen or oxygen.

Wherein the first gas cartridge and the second gas cartridge can be configured to be modular and replaceable. The amount of gas filled in the first gas cartridge and the second gas cartridge can be displayed on the display portion disposed on the surface of the main body.

The mixing section mixes the gases of the first gas cartridge and the second gas cartridge at a preset mixing ratio, and then supplies the mixed gas around the power supply electrode 101. [ At this time, the mixing portion can supply the gas around the power supply electrode 101 and supply the gas around the power supply electrode 101 without mixing the gases of the first gas cartridge and the second gas cartridge in advance.

Next, as a second embodiment of the gas supply unit 110, the gas supply unit 110 may include a first gas cartridge, an atmospheric compression unit, and a mixing unit.

The first gas cartridge accommodates a carrier gas of argon or helium, and the atmospheric compression unit compresses and accommodates the atmospheric air.

Wherein the first gas cartridge can be configured to be modular and replaceable. The amount of gas charged in the first gas cartridge and the atmosphere compression section can be displayed on a display section disposed on the surface of the main body.

The atmospheric compression section may be configured to compress and store air in the atmosphere.

In another embodiment of the atmospheric compression unit, the atmospheric compression unit includes a first sub-cartridge storing nitrogen, a second sub-cartridge storing oxygen, a third sub-cartridge storing hydrogen, 4 sub-cartridges.

The atmospheric compression unit may adjust the mixing ratio of the gas stored in each of the first to fourth sub-cartridges and transmit the mixture to the mixing unit. At this time, since the air stored in the fourth sub-cartridge is stored by compressing the external air, the compression ratio of the air can be adjusted as necessary.

Basically, the portable plasma aesthetic apparatus 10 can control to generate a plasma after supplying the gas stored in the above-mentioned cartridge to the power supply electrode 101 by mixing-argon or helium.

However, in the absence of argon or helium, a plasma can be generated by generating outside air and convection in the discharge space without using a catalytic gas such as argon or helium.

Particularly, it is possible to control the generation of plasma by reacting oxygen, hydrogen, moisture, nitrogen, etc. contained in the air. Particularly, it is possible to stabilize the plasma discharge by controlling the amount of water and to generate an OH radical (hydroxyl group). The OH radical can sterilize and deodorize. Such a mixing ratio may be adjusted in the mixing portion of the gas supply portion 110.

The power supply unit 120 supplies driving power to the power supply electrode 101 and the ground electrode 102 in the main body to control plasma generation.

Basically, the power supply unit 120 is configured to convert the DC power stored in the battery into an AC power of several to several tens of kHz, and then supply the AC power to the power electrode 101.

The charge control unit of the power supply unit 120 can control not only the battery using the external power source applied through the charge terminal but also the drive power source to supply the power source electrode 101 at the same time as charging the battery.

The battery is built in the form of a rechargeable secondary battery. Basically, the rechargeable battery may be provided with a primary battery or only a primary battery according to an embodiment of the present invention.

Meanwhile, the battery is configured by a plurality of battery cells, and the charge controller may be configured to selectively charge at least one of the plurality of battery cells according to the magnitude of the charge power.

Basically, since the external power supplied through the charging terminal is used as the charging power, the magnitude of the charging power is basically constant. However, when the driving power is supplied to the internal circuit and the battery is charged, the magnitude of the charging power supplied to the battery is changed according to the driving power consumption of the internal circuit. Hereinafter, the charging method of the battery will be described in detail.

It is assumed that when three battery cells are arranged, that is, the first battery cell, the second battery cell and the third battery cell are arranged. Here, it is assumed that the charging capacity of the first battery cell is the largest, the charging capacity of the second battery cell is smaller than that of the first battery cell, and the charging capacity of the third battery cell is smaller than that of the second battery cell.

The charge control unit charges the first battery cell in the first section, charges the second battery cell in the second section, and charges the third battery cell in the third section while sensing the magnitude of the charging power. That is, as the charging power is increased, the battery cells having larger capacity can be charged first to improve the charging efficiency.

At this time, when the second section is continuously maintained and the second battery cell is fully charged, the charge controller adjusts the charge priority so that the battery cell of the smallest capacity among the remaining battery cells is first charged.

On the other hand, when discharging the plurality of battery cells, the charge control unit senses the charged amount of the first battery cell, the second battery cell, and the third battery cell, and then supplies the power of the battery cell to the internal circuit first do.

For example, when the charging amount of the first battery cell is 60%, the charging amount of the second battery cell is 70%, and the charging amount of the third battery cell is 80%

The power of the third battery cell is supplied to the internal circuit first, and when the charged amount reaches 40%, the power supply of the third battery cell is cut off and the power of the second battery cell is supplied to the internal circuit. When the charged amount of the second battery cell reaches 40%, the power supply of the second battery cell is cut off and the power of the first battery cell is supplied to the internal circuit.

When all of the first through third battery cells are charged to less than 40%, the charge controller connects the first through third battery cells in parallel to supply power to the internal circuit.

The charge control unit transfers the charge power of the first battery cell to the second and third battery cells while maintaining the charge amount at 90% or more when the first battery cell having the largest charge capacity is charged to 90% or more.

On the other hand, the head 130 is coupled to one end of the main body so as to be rotatable, and emits plasma in a rotated direction. The angle of rotation of the head can be set between 0 and 60 degrees.

The auxiliary head 140 is detachably attached to the head 130 and is configured to adjust the radiation range of the plasma. A description of the auxiliary head 140 will be given later.

The speed sensing sensor 150 senses the moving speed of the main body. The speed sensing sensor 150 may be an infrared sensor or a laser sensor, or a method of measuring the rotational speed of a trackball added to the end of the head 130 may be used.

The vibration means 160 generates vibration when the plasma is radiated for a longer time than the set safety time in a state where the moving speed of the main body is less than the set safe speed.

That is, when the moving speed of the main body is very slow than the safe speed and the plasma is radiated for longer than the safety time, the accumulation amount of the plasma radiated to the skin may exceed the safe amount, .

For example, when the plasma is radiated to the skin in excess of the safety time of 10 minutes to 20 minutes under the condition of less than the safety speed of 3 to 5 mm / s, vibration is generated. When the vibration exceeds 5 to 10 times, Radiation is automatically terminated.

The skin condition detection sensor 170 is constituted by a sensor for detecting the oil and moisture state of the skin, and at least one sensor for detecting the oil content of the skin and a sensor for detecting the moisture of the skin may be disposed.

The wireless communication module 180 transmits data sensed by the skin condition sensor 170 to the external portable terminal 20. Here, the wireless communication module 180 can transmit data using a WIFI communication method or a Bluetooth communication method. For reference, the portable terminal 20 collectively refers to a portable device such as a mobile phone, a smart phone, and a smart pad, which the user can use while carrying on the portable terminal. In the present embodiment, the portable terminal 20 is assumed to be a portable terminal configured as a smart phone.

Accordingly, the user can confirm the oil and moisture state of the skin by numerical values through the portable terminal 20.

The camera 190 captures an image of the skin, and the captured image is transmitted to the external portable terminal 20 through the wireless communication module 180.

Accordingly, the user can confirm the skin image through the portable terminal 20, and the portable terminal 20 analyzes the skin image to determine the skin condition (dry, neutral, intelligent) and the degree of whitening of the user And display it as a numerical value.

At this time, the portable terminal 20 can additionally receive the indoor humidity of the current space and the body temperature information of the user as well as the skin photographing image, so that the user can more accurately determine the state of the user's skin (dryness, neutrality, intelligence).

That is, the portable terminal 20 can further consider the state of the skin that changes according to the user's body temperature and indoor humidity when checking the state of the skin (dryness, neutrality, intelligibility) through the skin image of the user.

Meanwhile, as another embodiment, the camera 190 and the portable terminal 20 may be connected to each other by wire to exchange data with each other. At this time, the camera is provided with a wired connection terminal for transmitting the photographed image to an external portable terminal.

For example, when the state of the skin (dryness, neutrality, and intelligibility) judged by the portable terminal 20 is provided to the portable plasma beauty apparatus 10, the portable plasma beauty apparatus 10 can be applied to dry, (Plasma intensity, spinning time) can be automatically adjusted according to a preset program in correspondence with each other.
