Description

Skin electric device and method for driving the same

Technical Field

The present invention relates to an electrical apparatus for skin and a method of driving the same, and more particularly, to an electrical apparatus for skin and a method of driving the same, which can directly control the intensity of plasma generated by adjusting the area of the plasma generated, in order to change the output intensity of plasma while maintaining a stable high voltage output, even when a user selects different plasma (plasma) output intensities.

Background

With the continuous development of the anti-aging industry, the market of medical devices related to facial beauty and skin beauty has been greatly developed. According to the contents released by a certain research institute in korea in 2015, the market size of medical devices related to skin beauty is rapidly increased at a rate of about 7% per year on average, and a huge market size of 36 billion dollars is expected to be reached in 2017. This is because the awareness of the appearance of women has changed greatly with the increase in participation in social activities, and clinics and hospitals such as dermatology and plastic surgery have put a lot of effort in the fields related to skin beauty in order to get rid of operational difficulties.

The current skin beauty medical devices adopt a non-incision mode and comprise various devices utilizing laser, ultrasonic waves and plasma. Particularly, with the recent mass emergence of portable cosmetic devices using plasma, more and more general people have started to pay attention to skin peeling beauty and treatment.

Plasma is called a 4 th class substance other than solid, liquid, and gas, and is generally artificially generated by arc (arc) induction based on high-voltage discharge, and when the current value is appropriately adjusted to a value of several mA or less which does not cause damage to the human body and is induced to the skin by an action similar to that of a skin treatment laser, it can be used for the purpose of treatment and shaping of the skin epidermis portion by a sublimation (sublimation) action.

Currently, arc-induced plasma electro-surgical devices have been disclosed in connection therewith. However, in the above-described apparatus, since the method of adjusting the voltage value when the high voltage is generated is used to adjust the output intensity of the plasma, there is a problem that the plasma output is not uniform when the magnitude of the high voltage is changed, and it is difficult to achieve a uniform therapeutic effect because the distance at which the plasma discharge is generated varies with the magnitude of the high voltage when the treatment is performed near the skin.

Detailed Description

Next, an embodiment to which the present invention is applied will be described in detail with reference to the drawings.

Fig. 1 is an exemplary diagram illustrating an electrical skin device to which embodiment 1 of the present invention is applied, and fig. 2 is a schematic diagram illustrating an internal configuration in fig. 1.

As shown in FIGS. 1 and 2, an electrical skin device (for example, a skin cosmetic device) to which embodiment 1 of the present invention is applied includes: a main body case 100; a driving section (or driving device) 110; and, the interface part 120-1 ~ 120-6; a part or all of them.

The phrase "including a part or all of" means that some of the components such as the interface units 120-1 to 120-6 can be integrated with other components such as the driving unit 110. In order to facilitate a more complete understanding of the present invention, the following description will be given by taking the case of including all cases as an example.

First, the main body case 100 includes: a 1 st housing 100-1 disposed on an upper side as viewed in fig. 1; a 2 nd housing 100-2 disposed at a lower side; 100-3 of an end cover; and, a support table 100-4 in fig. 2. As shown in fig. 2, the support base 100-4 may be integrally formed with the upper cover 100-1. Here, "integrally formed" means that it can be formed so as to be fixed to the upper cover. As shown in fig. 2, the 1 st substrate on which the control part 200 is formed can be disposed at a certain distance from the 2 nd substrate on which the plasma generation part 220 is formed by the support table 100-4, whereby the 1 st substrate, which is the main board on which the control part 200 is disposed, can be prevented from being affected by interference due to a high voltage generated in the plasma generation part 220. The cap 100-3 is a cover that is fixed after the needle (bit) 230 is inserted.

The driving unit 110 may include: a charging section 110-1; the needle engaging portion 110-2 is a clip portion; a control unit 200; a power storage unit 210; a plasma generation section 220; and, a needle 230; a part or all of them. As shown in fig. 2, the control part 220 is formed on the 1 st substrate and the 1 st substrate is attached to one side of the 1 st housing 100-1, and the other side of the 1 st substrate is equipped with a power storage part 210, such as a battery. The plasma generating part 220 is formed on the 2 nd substrate, and is disposed in the main body case 100 as close to the treatment site as possible in order to minimize loss when generating plasma and to transmit energy to the skin target site. The plasma generation unit 220 is separated from the 1 st substrate, which is a main board on which the control unit 200 is formed, and is disposed so that the influence of disturbance due to a high voltage of the main board can be minimized. Although the 1 st substrate and the 2 nd substrate are not separately shown in the drawings, electrical connection can be achieved by a wire or a cable connected to a connector. Further, the 2 nd substrate on which the plasma generating part 220 is formed is fixed by 2 supporting stages 100-4 disposed at the front side of the 1 st housing 100-1. Wherein the front side refers to the direction in which the needle 230 is located.

Charging unit 110-1 is mounted on a separate charger to perform a charging operation, and transmits a voltage to power storage unit 210 to perform charging. In the above process, the charging part 110-1 can convert the input AC voltage into a DC voltage and store it to the power storage part 210. The needle bonding portion 110-2 is a portion for bonding the needle 230.

The interface part 120-1 to 120-6 can include: user interface parts 120-1, 120-2, 120-4 to 120-6, which receive user instructions through the interface (interface) with the user; and a display part 120-3 for displaying the working state of the apparatus to the user; and the like. More specifically, as shown in FIG. 1, the interface parts 120-1 to 120-6 to which the embodiment of the present invention is applied include: an output indicator light 120-1; a radial button 120-2; a display section 120-3; mode button 120-4; power/level button 120-5; and, a memory button 120-6. The output indicator lamp 120-1 is an indicator lamp for indicating the plasma output state. The emission button 120-2 is an operation button for outputting plasma, the display unit 120-3 is a screen for displaying an operation state and a setting value, and the mode button 120-4 can be used to select 5 continuous or pulse modes. The power/level button 120-5 can be used to turn ON/OFF (ON/OFF) the power or select 3 levels of output intensity. When the long press is more than 2 seconds, the power supply can be turned off. Or when no button operation is performed within 5 minutes, the power can be automatically turned off. The memory button 120-6 can be used to read the 3 memory settings set by the user.

Fig. 3 is a schematic diagram illustrating an upper side and a rear side of the plasma generation apparatus in fig. 2, fig. 4 is a schematic diagram illustrating an upper side and a front side of the plasma generation unit (e.g., plasma adjustment unit) illustrated in fig. 3, and fig. 5 is a schematic diagram illustrating a principle of generating plasma in the plasma generation unit illustrated in fig. 4.

As shown in fig. 3 to 5, a plasma generation apparatus 220 as a plasma generation unit to which the embodiment of the present invention is applied includes: a substrate 300; a connector 310 provided on one side of the substrate 300; a high voltage generating section 320; and, a plasma generating section 330; wherein "a part or all" is included as the same meaning as explained above.

The substrate 300 is an insulating PCB substrate, and may be made of ceramic or an electrolyte made of FR4 material. The substrate 300 constituting the plasma generating portion is the 2 nd substrate to which the embodiment of the present invention is applied, and can receive the voltage and various types of (control) signals from the 1 st substrate as described above through the connector 310. For example, the received voltage is applied to the high voltage generating part 320. More specifically, since the high voltage generating part 320 includes a high voltage transformer, it is possible to form a secondary voltage of a high voltage by operating in a full bridge manner of a voltage loaded into a primary side terminal (e.g., a coil) and to supply to the plasma generating part 330. In the embodiment to which the present invention is applied, the high voltage generated in the high voltage generating part 320 is named as the 1 st high voltage. In the embodiment to which the present invention is applied, the 1 st high voltage described above is continuously maintained at a stable level. For example, a voltage of 1500V is applied to the plasma generation unit 330 at a stable level without increase or decrease.

Further, as shown in fig. 3, a plasma generation part 330 is formed on the substrate 300. As shown in fig. 4, the plasma generation unit 330 to which the embodiment of the present invention is applied includes: the 1 st electrode 400; the 2 nd electrode 410; and a plurality of switching elements 420-1, 420-2. The 1 st electrode 400 and the 2 nd electrode 410 have the same or similar areas facing each other with the substrate 300 interposed therebetween. In the embodiment to which the present invention is applied, a portion of the substrate 300 corresponding to the area of the 1 st electrode 400 and the 2 nd electrode 410 facing each other may be named as an electrolyte portion 300-1. The electrolyte part 300-1 may be made of the same material as the substrate 300 or a different material from the substrate 300 as a part of the substrate 300, and thus is not limited to a specific form in the embodiment to which the present invention is applied. Only one electrode is formed as the 1 st electrode 400 and a plurality of electrodes are separately formed as the 2 nd electrode 410 on the basis of the area facing the electrolyte part 300-1. However, in the embodiment to which the present invention is applied, the electrode described above is not limited to a specific form. In other words, any form can be used as long as the plasma generation area can be adjusted.

As shown in fig. 4, 3 second electrodes 410 are formed, and the respective second electrodes 410 are electrically connected or insulated by switching elements 420-1 and 420-2. In other words, the switching elements 420-1 and 420-2 can include, for example, a small-sized high voltage lead relay (lead relay), and can achieve electrical connection or insulation between the separated electrodes by performing a switching action based on an external control signal. Information related thereto will be described in detail later. By the above-described operation, plasma corresponding to a plurality of levels of the 2 nd high voltage can be generated in the plasma generation unit 330. For example, in a state where the 1 st high voltage of 1500V is applied from the high voltage generating unit 320, the plasma generating unit 330 can generate the 2 nd high voltage of 1000V according to a user instruction and generate plasma corresponding thereto.

As shown in fig. 5, the 1 st high voltage generated in the high voltage generating part 320 shown in fig. 3 is applied to the 1 st electrode 400 of the plasma generating part 330 shown in fig. 3 and 4. At this time, since the 2 nd electrode 410 of the plasma generating part 330 is grounded 500 by the human body, it is considered that the electrolyte is positioned between the 1 st electrode 400 and the skin, and the high voltage applied to the 1 st electrode 400 by the electrolyte as described above is different from the electric discharge (arc), and plasma is formed and transmitted to the skin in the form of micro streamer (micro streamer). This is in contrast to the situation where a high voltage discharge is formed when the high voltage is in direct proximity to and in contact with the skin. Wherein the 2 nd electrode 410 can also be independently additionally connected to the base ground of the (circuit).

As described above, the high voltage generated in the high voltage transformer of the high voltage generating part 320 can be regarded as being directly applied to the 1 st electrode 400, for example, the copper plate, so that the high voltage energy is directly transferred, and the high voltage is converted into a plasma form in the process of being transferred to the upper 2 nd electrode 410 via the electrolyte. Instead of forming one 1 st electrode on the lower surface, 32 nd electrodes 410 in a rectangular shape are formed on the upper surface, respectively, and the 32 nd electrodes 410 can generate a required 2 nd high voltage by switching elements 420-1 and 420-2, and generate plasma by using the different high voltages formed, respectively.

Fig. 6 is a schematic diagram for explaining the operation principle of the plasma generating section in fig. 4.

As shown in fig. 6, the plasma generation part 330 shown in fig. 4 to which the embodiment of the present invention is applied can be operated in 3 states shown in fig. 6 (a) to (c). In an embodiment to which the present invention is applied, the states as described above can be named as 1 st mode to 3 rd mode, respectively, where "mode (mode)" refers to a manner of operating in the states as (a) to (c) of fig. 6 set according to the 1 st instruction to 3 rd instruction of the user.

In the embodiment to which the present invention is applied, as shown in fig. 6, the plasma output can be directly controlled by adjusting the area of the plasma generation electrode, and the plasma output proportional to the area of the electrode can be calculated by the charge amount transfer formula shown below.

Equation 1

(wherein k is the dielectric constant of the electrolyte,. epsilon.o is the vacuum dielectric constant, A is the area of the parallel plates (or electrodes), and d is the distance between the parallel plates)

The switching elements 420-1 and 420-2 in fig. 4 are small-sized high-voltage lead relays, and can switch at most 4000V, and thus 1500V generated by the high-voltage generating unit 320 can be easily switched.

As shown in (a) of fig. 6, in the 2 nd high voltage state of level 1, i.e., level 1, the plasma generating part 330 outputs plasma only through the 2 nd electrode 410-1 because both the 1 st switching element 420-1 and the 2 nd switching element 420-2 are turned off.

In addition, as shown in (b) of fig. 6, in the 2 nd high voltage state of level 2, that is, 2 nd level, since only the 1 st switching element 420-1 in the plasma generating part 330 is turned on, plasma will be output over the area of 2 nd electrodes 410-1, 410-2.

In addition, as shown in FIG. 6 (c), in the 2 nd high voltage state of level 3, i.e., 3 rd level, since the 1 st switching element 420-1 and the 2 nd switching element 420-2 in the plasma generating part 330 are both turned on, plasma is outputted over the area of the 32 nd electrodes 410-1 to 410-3.

As shown in fig. 6 (a) to (c), the activation states of the 2 nd electrodes 410-1 to 410-3 in the embodiment to which the present invention is applied are shown by hatching (hashing).

Fig. 7 is a block diagram illustrating the driving mechanism in fig. 1.

As shown in fig. 7, an electrical skin device 90 to which embodiment 1 of the present invention is applied includes: a power generation unit 700; a control unit 710; a plasma generation section 720; a display section 730; and an interface section 740; wherein "includes a part or all" has the same meaning as explained above.

The power generation unit 700 stores power input from the outside in a power storage unit 703, such as a battery, and supplies the stored power to the high voltage generation unit 721 under the control of the control unit 710. For example, the power storage unit 703 may include a lithium polymer rechargeable battery having a capacity of 7.4V and 1000 mAh. Thereby, after the power button is pressed, the power can be turned on and controlled by means of the control of the switching element such as the FET element. The switching element may be disposed in the power supply control unit 701. The power supply control unit 701 can load a voltage as a control signal for controlling on/off of a full bridge (full bridge) switching element constituting the high voltage generation unit 721 and the switching unit 723. In general, a clock signal of 5V can be used as the control voltage.

As described above, the control unit 710 controls the overall operation of the electrical skin device 90. When a user instruction is received via the interface unit 740, plasma having a strength corresponding to the user instruction is output by control. That is, the electrical dermatological apparatus 90 is operated in the 1 st mode in response to the 1 st command, in the 2 nd mode in response to the 2 nd command, and in the 3 rd mode in response to the 3 rd command. Here, the 1 st to 3 rd modes can be regarded as a mode in which the control section 710 controls the plasma generation section 725. That is, the plasma generation section 725 adjusts the intensity of the plasma according to different modes.

In addition, the control unit 710 outputs a DC voltage (for example, 5V) to the high voltage generation unit 721 by controlling the power supply control unit 701, and controls the switch unit 723 constituting the switching element in a full-bridge manner by the power supply control unit 701, so that the high voltage generation unit 721 performs a method for the input 5V voltage to generate a high voltage of 1500V and output it to the plasma generation unit 725.

The plasma generating part 720 includes: a high voltage generation unit 721; a switching section 723; a plasma generation section (or plasma adjustment section) 725; and, the bit engaging portion 727; a part or all of them. The high voltage generator 721 amplifies the 5V voltage input from the power supply controller 701 by the full-bridge operation of the switch 723, and supplies the generated high voltage to the plasma generator 725. In an embodiment to which the present invention is applied, the high voltage generated at the high voltage generating part 721 can be named as a 1 st high voltage. The plasma generation unit 725 generates 2 nd high voltage of different levels according to the received user command by using the 1 st high voltage inputted. For example, the 2 nd high voltage of the 1 st level to the 2 nd high voltage of the 3 rd level can be generated, and the related contents have been sufficiently described in the above-mentioned contents in conjunction with fig. 6, so the related detailed description will be omitted here. As described above, the plasma of different intensities respectively generated by the plasma generating parts 725 are transmitted to the skin through the bit combined into the bit combining part 727, i.e., the needle 230 shown in fig. 2.

Specifically, the switch unit 723 includes a full-bridge control unit including 4 FET elements, and pulse-drives the high-voltage transformer of the high-voltage generator 721 at a frequency of 50 to 100kHz, and amplifies a voltage of 5V rectified by a battery to a voltage of 1500V by the high-voltage transformer. As described above, in order to generate plasma so that the plasma is generated while passing through the ceramic constituting the plasma generation part 725 having an insulating effect and the electrolyte (part) 725-1 such as FR4, the plasma intensity is further adjusted by controlling the generation area by the 2 lead relay parts 725-2 and 725-3. The generated plasma, whose intensity is controlled, is transferred to the skin tissue via the needle 230 of the metallic treatment tool bit connected by means of the cartridge made of metal material such as brass, stainless steel, etc.

As shown in fig. 8, an electrical skin appliance 90 according to embodiment 2 of the present invention includes: a plasma generation section 800; a control section 810; and an interface section 820; wherein "includes a part or all" has the same meaning as explained above.

The plasma generation unit 800 may include: a high voltage generating part 800-1; and a plasma adjustment unit 800-2. The high voltage generating part 800-1 generates the 1 st high voltage and supplies it to the plasma adjusting part 800-2. The plasma adjusting part 800-2 can generate 2 nd high voltages of a plurality of levels using the 1 st high voltage under the control of the control part 810. More precisely, it can be considered that 2 nd high voltages of a plurality of levels are selectively generated. Further, the plasma adjusting section 800-2 generates and outputs plasma corresponding to the 2 nd high voltage of a specific level. The relevant contents have already been fully described in the above, so a detailed description thereof will be omitted here. Therefore, in the embodiment to which the present invention is applied, a method of generating and outputting plasma is not particularly limited. This is because the electrode shape can be changed to a plurality of different shapes, for example.

The control unit 810 controls the plasma generation unit 800 in accordance with a user command received from the interface unit 820. For example, in response to an instruction from a user, for example, a doctor, to reduce the plasma intensity, the control unit 810 can control the plasma adjustment unit 800-2 to output the adjusted plasma.

The interface 820 can receive a user command by, for example, a button. Wherein the user command can correspond to a command for adjusting the plasma intensity. Further, since the user command can be received in various forms such as a button and a wireless method, the interface unit 820 is not limited to a specific form such as a button and a wireless communication module.

Except for this point, the details of the plasma generation unit 800, the control unit 810, and the interface unit 820 are similar to those described with reference to fig. 7, and therefore, the above description is directly substituted.

Fig. 9 is a flowchart illustrating a driving process of the electrical skin appliance to which the embodiment of the present invention is applied.

As shown in fig. 9 and 8, in step S900, the electrical skin device 190 to which the embodiment of the present invention is applied receives a user instruction for adjusting the intensity of plasma irradiated to the skin.

Next, in step S910, the plasma generation unit 800 of the electrical skin device 190 selectively generates and outputs plasma corresponding to the 2 nd high voltage of each of the plurality of levels by using the designated 1 st high voltage.

Next, in step S920, the galvanic skin appliance 190 generates the 2 nd high voltage of a specific level selected in accordance with the received user command among the 2 nd high voltages of a plurality of levels by controlling the plasma generation unit 800. That is, the plasma generation unit 800 outputs plasma corresponding to the level of the 2 nd high voltage determined according to the received user command.

As shown in fig. 10 and 1, the electrical skin device 90 to which the embodiment of the present invention is applied is powered on in step S1000, and then the OLED of the display portion and the system are initialized in step S1010.

Next, in steps S1020, S1021, and S1022, the galvanic skin appliance 90 performs an auto-power-off check operation to check whether there is no user selection operation on the button after a lapse of time.

In step S1012, when the radiation button 120-2 in fig. 1 is selected, the skin electric device 90 can generate an output pulse, i.e., a control signal, for generating plasma. Thereby, the skin electric device 90 outputs plasma of a predetermined specific intensity. That is, the FET elements integrated into the IC are controlled by driving the full-bridge driving chip by a control Unit, which is an MCU (Micro Controller Unit), in a state where a predetermined plasma intensity is set, and a high voltage pulse is generated by a high voltage transformer.

However, in the case where the radial button 120-2 is not selected, the skin electric device 90 can perform different actions according to the selection of the level increasing or decreasing button or the selection of the menu button.

Specifically, in steps S1013 and 1014, the electrodermal device 90 is operated so as to be able to output plasma of the intensity corresponding thereto when the level increasing button is selected, and in steps S1015 and 1016, is operated so as to be able to output plasma of the intensity corresponding thereto when the level decreasing button is selected. Next, in steps S1017 and S1018, the electrical skin device 90 enters the menu state when the menu button is selected, and displays the relevant information on the display unit.

Here, since the level increase or level decrease is related to the adjustment of the plasma generation area as described above, for example, the switching elements 420-1 and 420-2 in fig. 4 can be controlled to adjust the generation area of the 2 nd electrode 410, and thus, a detailed description thereof will be omitted.

The skin electric apparatus 90 can set the driving method thereof by a menu button, and the driving method can include a continuous mode and a pulse mode.
