Description

Skin care device, driving method and computer readable recording medium {Apparatus for Managing Skin, Driving Method of Apparatus for Managing Skin, and Computer Readable Recording Medium}

The present invention relates to a skin care device, a method of driving the skin care device, and a computer-readable recording medium, and more particularly, a skin care device to which an electroporation technology capable of changing a low voltage frequency while having both a high voltage and a low voltage output is applied. The present invention relates to a method of driving a skin care device and a computer readable recording medium.

In general, as a person ages, the skin loses its elasticity, and wrinkles and sagging occur on the skin. Because of this, people use various kinds of functional cosmetics to maintain the elasticity of the skin. However, since the skin has a function of protecting the human body from external stimuli or substances and exhibits an impermeable property to water-soluble ingredients, it is not possible to effectively care for the skin simply by applying functional cosmetics to the skin. On the contrary, various types of skin care devices have been developed. Skin care devices include a variety of devices, such as a device for removing skin wastes using current, a device for managing skin using vibration, low frequency, galvanic, heat and ozone. In recent years, there is also a study on a skin care device that supplies hydrogen water to the skin, which contributes to eliminating free radicals that age blood, blood vessels, and cells.

Recently, he seems also tend to use by combining the electroporation technology for beauty equipment. Electroporation is a method of introducing a gene into a cell, and is a method of applying an electric field (or high voltage) to a cell to increase membrane permeability and introducing DNA into the cell. However, the conventional electroporation device or the ion introducer simply outputs a frequency for promoting absorption without considering the degree of skin drying of the user.

In addition, the conventional high voltage electroporation uses a high voltage of several hundred or several kilo volts, but has a short pulse width to induce electrical perforation between the cell membranes of the skin, which is difficult to use continuously and applied to the face area. There is a problem that can be accompanied by pain.

In addition, for sensitive skin and hair, such as atopic or acne skin, applying the drug first and then using the electroporation device is less hygienic and less professional. In other words, for sensitive skin such as atopic or acne skin, if you apply the drug in an environment where hygiene is not guaranteed, you may be infected with the bacteria and worsen the condition of the skin. There is a problem in that the amount of the active ingredient that touches the scalp is less effective to absorb effectively because it falls.

The frequency of the low voltage may be selected in the range of 1 kHz to 40 kHz.

In addition, the method for driving a skin care device according to an embodiment of the present invention generates a high voltage and a low voltage of a specified size for use in the skin irritation of the user, changing the frequency of the generated low voltage, the skin condition of the user Changing the frequency according to the step, generating skin information related to the skin condition, and adjusting the active ingredient corresponding to the changed frequency to be introduced into the skin of the user based on the generated skin information. .

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

1 is a view showing a skin care system according to an embodiment of the present invention, Figure 2 is a view illustrating a cartridge used in the skin care device of FIG.

As shown in FIG. 1, the skin care system 90 according to the embodiment of the present invention includes a skin care device 100 and a cartridge 110.

The skin care apparatus 100 according to the embodiment of the present invention may include an outer case and an accommodating part capable of inserting (or storing) the cartridge 110 in one region of the outer case. For convenience of description, FIG. 1 illustrates the insertion of a syringe type cartridge 110 into the center of the outer case. However, if the cartridge 110 is a structure that can be accommodated in the skin care device 100 or a structure that can be attached or detached, It doesn't matter in form.

In addition, the cartridge 110 is inserted into the skin care device 100 to automatically insert the active ingredient and / or drug (hereinafter, the active ingredient 111) in the cartridge 110 to the user's skin properly It is preferable to have. For example, when the cartridge 110 in the form of a syringe is inserted into the skin care device 100, the amount of the active ingredient 111 may be adjusted by controlling the force applied to the rear end of the cartridge 110. In addition, the skin care device 100 according to an embodiment of the present invention may have a structure that can be selected between automatic and manual. For example, when the user automatically selects a button, the skin care device 100 automatically controls the cartridge 110 inserted therein. If the user manually selects the button, the skin care device 100 may stop the automatic operation and allow the user to apply a force directly to the cartridge 110, for example, a cartridge 110 in the form of a syringe. In addition, since the skin care device 100 may recognize the product code of the inserted product and the like, it may be possible to automatically and manually select and operate the inserted product.

For example, in the case of using the cartridge 110 in the form of a syringe and controlled manually, it may be useful in the case of scalp that is difficult to access by covering the hair. In addition, when the skin care apparatus 100 is manufactured with a detachable structure, the cartridge 110 may be formed as a disposable consumable, thereby providing more hygienic treatment to atopic or acne-sensitive skin sensitive to bacteria. By using the consumables of the cartridge 110, the skin care device 100 is designed to effectively deliver various effective ingredients 111, such as atopic skin, acne skin or hair, by spraying the medicine professionally.

As can be seen in Figure 1, the skin care device 100 according to an embodiment of the present invention has a positive (+) and a negative (-) electrode for outputting a high voltage and a low voltage in order to stimulate the skin of the user It includes the electrode portion (100-2, 100-3) having, and may further include an injection hole (100-1) is injected from the cartridge 110, the active ingredient 111. The skin care device 100 may output a high voltage and a low voltage through the electrode parts 100-2 and 100-3 to stimulate the skin of the user during an initial operation. In addition, the skin care apparatus 100 may simultaneously spray the active ingredient 111 through the injection hole 100-1 when the high voltage is output or at the time of outputting or during the low voltage output. When the injection of the active ingredient 111 as described above, the skin care device 100 again measures the skin resistance, for example, the degree of drying of the user through the electrode unit (100-2, 100-3) You might want to measure it. The measurement of the skin condition may be used to determine the information in which the skin passage is formed at the time when the high voltage is output. As a result of the measurement of the skin condition, it is determined that the formation of the skin passage is completed when the designated measurement value is detected.

When the skin condition improves as a result of measuring the skin resistance as described above, the skin care device 100 may adjust the amount of the active ingredient 111 injected through the injection hole 100-1. For example, after forming a skin passage by high voltage and changing to low voltage to measure skin resistance, when the skin is very dry due to high skin resistance, the amount of the active ingredient 111 is increased or the injection time is increased. . Of course, the combination operation may be possible. However, when the skin condition is improved, the skin care device 100 may reduce the amount of the active ingredient 111 added. As such, the skin care device 100 may adjust the amount of skin irritation while adjusting the amount of the active ingredient 111 injected. In other words, the skin irritation degree is adjusted to a low voltage at a fixed frequency at a high voltage, but the amount of the active ingredient 111 is adjusted.

In more detail, in the embodiment of the present invention, a method of adjusting the input amount of the low voltage and the active ingredient 111 of a fixed frequency, and the low voltage and the effective ingredient 111 of the multi-frequency determined in the designated active ingredient 111 It may be possible to fix the input. In the embodiment of the present invention, the latter scheme is preferably viewed, but it is not particularly limited to either scheme. For example, in order to use a multi-frequency low voltage, the skin care device 100 may initially have hundreds of short pulse widths to induce electrical perforation between the cell membranes of the skin, ie to form a skin passageway. A high voltage of several kilovolts, that is, a high voltage may be provided through the electrode parts 100-2 and 100-3. After a period of time, a low voltage of several tens of volts or less is used to reduce the puncture effect of forming a gap between the phospholipid bilayers of the skin layer. This can provide a long time skin irritation to a relatively large area. In other words, the high voltage and the low voltage pulse to have a unique skin passage function to each other, while changing the frequency of the low voltage, that is to say the degree of improvement according to the input of the active ingredient 111 changes the active ingredient ( 111) can be promoted.

In detail, first, the skin care device 100 forms a skin passage with a pulse of high voltage to help act on the lipid double worms of the stratum corneum and effectively passes the first gateway through which cosmetics are absorbed by the skin. At this time, the high voltage has a maximum (peak voltage) of 500 Vpp and the frequency may be a pulse of 3 kHz. When the skin passage is formed using a high voltage, the voltage is changed to a low voltage to lower the stimulus intensity and continuously apply the multi-frequency to the skin to inject the active ingredient 111 for each skin layer below the stratum corneum, which is flexible. The combined mid-frequency, stratum corneum, epidermal layer to the dermal layer evenly to act on each skin layer. The maximum voltage of the low voltage is 50 Vpp, and the frequency can be selected from 1 kHz to 40 kHz. Of course, since the skin condition may be determined after the active ingredient 111 is input at the time of forming the skin passage at a high voltage, the skin condition may be changed to the low voltage. Thus, the embodiment of the present invention will not be limited to the above.

As soon as the active ingredient 111 is sprayed on the skin, the skin care device 100 may use a cartridge type electroporation to promote absorption using a specific frequency. The cartridge 110 contains functional cosmetics, an active ingredient 111, or the like, and the cartridge 110 is mounted on the skin care device 100 capable of performing the role of, for example, an electroporation device. In the head of the skin care device 100, the electrodes 100-2 and 100-3 are positioned in the diagonal direction with the positive electrode 100-2 and the negative electrode 100-3. In the center, the injection hole 100-1 through which the active ingredient 111 of the cartridge 110 may be injected may have a structure in which the cosmetic may come out from the skin care device 100.

At this time, the cartridge 110 is a consumable to be separated from the skin care device 100 when the contents are all used for single use. The injection unit (or injection hole) 115 of the cartridge 110 may be formed to be injected only when there is pressure by using the spring 113. At this time, the method of injecting the contents of the cartridge 110 may be used a method of automatically spraying a certain amount by using a motor, and can be manually injected to the user by applying pressure directly, which is individually to a separate device Not only can it be configured, but also can be configured in a manner that is combined in one device, in the embodiment of the present invention will not be specifically limited in what way.

To sum up again, the skin management unit 100 is for example the upper end of the (+) electrode (portion) and serving as the electroporation device according to embodiments of the present invention (-) measured through the electrodes (negative) voltage It can be seen from the skin resistance, the smaller the skin resistance value can be seen that the input of the active ingredient 111 in the cartridge 110 is made well. On the contrary, if the skin resistance is large, it may be determined that the input of the active ingredient 111 in the cartridge 110 is not performed properly. Therefore, when the voltage value is small by using the measured voltage value, a signal is sent to a power unit such as a motor that injects the active ingredient 111 into the skin to reduce the input amount of the cartridge 110 and form a skin passage again with a high voltage pulse. When the skin resistance decreases after the step is performed, when the input can be made properly, the signal is sent to the power unit to increase the input amount of the cartridge 110 so that the effective ingredient 111 is effectively injected.

3 is a block diagram showing the structure of the skin care device of FIG.

As shown in FIG. 3, the skin care device 100 according to the embodiment of the present invention includes a part or all of the voltage generator 300, the controller 310, and the active ingredient providing unit 320, and the user. It may further include an interface unit.

Here, "including some or all" means that some components such as the active ingredient providing unit 320 are omitted so that the skin care device 100 is configured or some components such as the voltage generating unit 300 are controlled by the control unit ( Meaning that it can be integrated into other components, such as 310, etc., it will be described as including all to help a full understanding of the invention.

The voltage generator 300 may generate and provide a high voltage or a low voltage under the control of the controller 310, and may change and output a frequency of the provided low voltage. The voltage generator 300 may include an electrode unit to provide the generated high voltage or low voltage to the user's skin. Here, in addition to outputting a high voltage and a low voltage, the electrode part may also play a role of measuring a skin condition under the control of the controller 310. For example, the controller 310 generates a high voltage at the first driving of the skin care device 100 and provides it to the electrode unit, or first measures the skin state through the electrode unit to determine the skin condition, and then high voltage through the electrode unit. Can be provided.

For example, the control unit 310 is the magnitude of the high voltage generated by the voltage generation unit 300 according to whether the surrounding environment is dry or wet in a state in which the electrode unit is exposed to the outside prior to the initial driving of the skin care device 100. Can be determined. For example, if the environment is wet, the resistance may come out small, so change the reference voltage information in consideration of this. As such, the voltage generator 300 may generate a high voltage according to the voltage magnitude information of the controller 310 and provide the high voltage to the electrode unit. Then, a passage is formed in the skin of the user through the high voltage. Applying high voltage electroporation instantaneously induces electrical perforation between the cell membranes of the skin, and a high voltage can be provided for a specified time.

When the high voltage is provided and the formation of the skin passage is completed, the input of the active ingredient is made or under the control of the controller 310, the voltage generator 300 changes the output high voltage to a low voltage and provides the skin to the user through the electrode part. can do. For example, a high voltage of several hundred to several kilovolts having a short pulse width is provided and then changed to a voltage of several tens of volts having a wide pulse width. The voltage generator 300 according to an embodiment of the present invention generates a high voltage and a low voltage through a single voltage generator to prevent the high voltage pulse circuit and the tens of volt voltage generation circuits from interfering with each other. Can be configured to be output. For this reason, the voltage generation unit 300 may receive the voltage magnitude and the frequency related information provided from the control unit 310 to determine the magnitude and frequency of the voltage based on this to generate a high voltage and a low voltage.

For example, the voltage generator 300 may output a low voltage through the electrode unit, and then change the frequency under the control of the controller 310 to output the low voltage. According to an embodiment of the present invention, the output time of the low voltage is determined depending on whether or not the low voltage should be applied. In other words, the state includes a gap between the phospholipid double worms of the skin layer, but it is considered to be a situation where a long time should be used for a relatively large area. The controller 310 may control the active ingredient providing unit 320 when the low voltage is output to spray the active ingredient (eg, drugs, cosmetics, etc.) to the user's skin. ) May measure the skin condition by controlling the voltage generator 300 and / or the electrode unit. For example, after a predetermined time has elapsed after outputting the low voltage, the skin state is measured through the same electrode part, and the low voltage is continuously output through the corresponding electrode part or the voltage of the changed frequency is output. In this process, the voltage generator 300 may be able to immediately measure the skin condition by using the output low voltage. However, when measuring the skin condition, the voltage generator 300 may be used to measure the skin condition by reducing the voltage level under the control of the controller 310. There will be.

The electrode unit of the voltage generator 300 may measure a degree of skin dryness to measure a skin condition, and for this, skin resistance may be measured. Then, the controller 310 may receive the voltage applied to both ends of the skin resistance measured by the electrode unit to determine the skin condition. For example, when the skin condition is measured after spraying the active ingredient at the time when high voltage or low voltage is provided, if the (skin) voltage across both ends of the skin resistance is small, the controller 310 indicates that the dryness of the skin is improved. To judge. In this case, when the measured state of the skin becomes good, the controller 310 may change the frequency of the voltage generator 300 to output a low voltage to promote absorption of the active ingredient. Accordingly, the voltage generator 300 outputs a low voltage under the control of the controller 310, outputs a low voltage for skin stimulation, and outputs a low voltage for measuring skin conditions, and further, measured skin during skin stimulation. Depending on the state, the frequency of the low voltage can be changed and output. Here, the frequency of the low voltage is preferably selected in the range of 1 Hz to 40 Hz as the intermediate frequency.

For example, the controller 310 may determine the drying information of the skin using the input skin voltage as follows. The controller 310 digitally converts the input skin voltage through an ADC (Analogue Digital Converter) to generate binary bit information in the form of machine language, and determine the skin condition using the generated binary, for example, 4-bit information. Can be. In other words, if '1111' is the dryest skin and is set (or stored) in the lookup table (LUT), it is determined by comparing the digitally converted 4-bit information with the dry state information stored in the lookup table. It is done.

The controller 310 controls the voltage generator 300 and the active ingredient providing unit 320. For example, when the user starts the operation of the skin care device 100 by pressing the power button, the control unit 310 may first measure the resistance measured through the electrode unit of the voltage generation unit 300 to determine the reference voltage. . In order to detect the surrounding environment, the temperature and humidity are measured once through the electrode unit, thereby generating an optimal voltage. Of course, this process may be omitted according to an embodiment of the present invention. Alternatively, the controller 310 controls the voltage generator 300 according to a preset method (voltage magnitude) to output a high voltage for generating a skin passage on the skin of the user. In addition, when a predetermined time elapses, that is, when generation of the skin passage is completed, the controller 310 may control the voltage generator 300 to change the output high voltage to a low voltage having a predetermined size and output the same. The high voltage can provide voltages up to 500 Vpp and the low voltage can provide voltages of 50 Vpp.

When a low voltage is provided or when a high voltage is provided, the controller 310 may control the active ingredient providing unit 320 to inject the active ingredient into the skin of the user. Alternatively, it can be controlled to provide a low voltage for a certain amount of time to make the skin softer and then add an active ingredient. This is because the designer of the skin care device 100 can be seen to operate according to a predetermined method based on the data obtained through clinical experiments, so that the embodiment of the present invention is not particularly limited to how to operate. .

In addition, the controller 310 may perform an operation for measuring the skin condition by using the low voltage currently applied when the active ingredient is input or reducing the magnitude of the low voltage. As will be described later, the controller 310 does not receive information related to the skin condition provided by the voltage generator 300 in the step of providing a low voltage for skin irritation. In such a process, when the skin condition needs to be measured, the controller 310 turns on a terminal for receiving information related to the skin condition and receives the received information. If the low voltage is used as it is for skin irritation and the skin voltage due to the skin resistance measured at the electrode part can be received, it will not be a big problem even if it has any structure.

As such, when information on the skin condition, for example, the skin voltage is received, the controller 310 determines the skin condition of the user based on the received skin voltage and controls the active ingredient providing unit 320 accordingly. For example, the control unit 310, the initial amount of the active ingredient is increased a lot while the skin condition improves to reduce the amount. In this process, the controller 310 may control the voltage generator 300 to fix the frequency of the low voltage output . When the controller 310 first outputs a low voltage, it may be desirable to give a skin stimulus while changing from a high frequency to a low frequency, and at the same time, spray the active ingredient on the skin of the user. For example, while measuring the skin condition at regular intervals, the amount of active ingredient is reduced accordingly, but the frequency of the low frequency can be fixed. In this case, the injected amount and the frequency of the specific low frequency may be measured through an experiment, and the data obtained through the measurement may be set by being reflected or reflected during manufacture of the skin care apparatus 100.

On the other hand, according to another embodiment of the present invention, when applying a low voltage, the frequency may be determined to be efficiently absorbed according to the effective ingredient 111 in multiple frequencies. Therefore, the part adjusted using the feedback skin resistance value is 1) forming a skin passage to help the active ingredient 111 acts on the lipid bilayer through high voltage, and 2) for each skin layer for a long time using low voltage. In order to administer the effective ingredient 111 using multiple frequencies composed of efficient frequencies. The skin resistance value is determined to determine whether the skin is well formed in the current skin passage can be seen to select the process of 1) and 2) above to administer the drug more efficiently. Therefore, the controller 310 may perform an operation for performing the above process.

The effective ingredient providing unit 320 may have various structures. According to an embodiment of the present invention, the effective ingredient providing unit 320 is preferably formed so that the replacement of the container or cartridge containing the active ingredient is easy, and can operate the cartridge in an automatic or manual manner. For example, suppose a user requests to operate a syringe-type cartridge manually through a user interface (eg, a button). In this case, the controller 310 may stop the operation of the active ingredient providing unit 320.

According to an embodiment of the present invention, the active ingredient providing unit 320 may include a motor driving unit and a container (for example, a cartridge) inserting unit. The cartridge inserted into the container insert is controlled by the control of the motor drive. For example, the controller 310 may provide a motor control value determined according to the measured skin condition of the user to the motor driver. Or the motor drive part can be controlled according to the motor control value. The motor driver may include a motor and a sub controller for controlling the motor, but for example, when the motor controller includes a sub controller, the motor driver may drive the motor by receiving a control value from the controller. If there is no sub controller, the controller 310 may directly drive the motor of the motor driver. The method of driving may vary, and therefore it is not particularly limited to any one method.

The motor driving unit may drive the motor to provide power to the cartridge, and thereby adjust the amount of the active ingredient injected through the nozzle of the cartridge. In this process, the active ingredient providing unit 320 may reduce the amount of the active ingredient is injected by increasing the speed in the direction opposite to the direction in which the motor is driven.

4 is a block diagram showing another structure of the skin care device of FIG.

As shown in FIG. 4, the skin care device 100 ′ according to another embodiment of the present invention includes a part or all of the voltage generator 400, the controller 410, and the cartridge power unit 420. It may further include a user interface, such as a power button, wherein "including all or part" is the same as the foregoing.

The voltage generator 400 may include a voltage generator 401 (eg, a pulse generator) and a voltage divider 402, and the voltage divider 402 may include an electrode unit 402a. For example, the voltage generator 401 generates a pulse voltage having a specified magnitude, generates a pulse voltage having a positive (+) and a negative (−) period, and provides the generated voltage to the voltage divider 402. In this case, the voltage generator 401 outputs a high voltage to form a skin passage under the control of the controller 410, and then changes the output high voltage to a low voltage to reduce skin irritation. In this case, the output high voltage and low voltage may be output through the electrode unit 402a. Of course, when the high voltage is provided, the controller 410 controls the cartridge power unit 420 to inject the active ingredient, measure the skin condition, and then change the low voltage according to the measurement result.

The voltage divider 402 distributes the voltage using the first resistor R ₁ and the second resistor R ₂ connected in series with each other. In this case, the voltage ratio of the first resistor R ₁ and the second resistor R ₂ may have a ratio of about 10: 1. I.e. the voltage that corresponds to the 10th of a first resistor (R ₁₎ to the second resistor (R ₂₎ is caught. And that the voltage across the second resistor (R ₂₎ is again reduced to a voltage of the third resistor (R ₃₎ and the third resistor (R ₃₎ and the electrode portions (402a) connected between the ground. That is, the electrode unit 402a may output high voltage and low voltage, and may be used for skin measurement when the controller 410 measures the skin condition. In this case, a voltage measured differently according to the state of the skin, that is, the skin voltage is provided to the controller 410. According to the exemplary embodiment of the present invention, the first resistor R ₁ and the second resistor R ₂ connected in series with each other may be referred to as a first resistor unit.

The magnitude of the reduced voltage is divided by the resistance ratio between the skin resistance read from the electrode unit 402a and the third resistor R ₃ , and is provided to the controller 410 as the skin voltage, and the controller 410 uses the skin voltage. It is to measure the degree of drying.

As illustrated in FIG. 1, the electrode unit 402a may form two negative electrodes and two positive electrodes in a diagonal direction in the head of the skin care device 100. Alternatively, it may include a wire (part) connected between one side terminal of the third resistor R ₃ and the ground and an electrode connected to two wires. In the embodiment of the present invention, since the active ingredient must be sprayed on the skin and at the same time, the former may be preferable. However, embodiments of the present invention will not be specifically limited to any one manner. Here, since the electrode may have internal resistance internally, the controller 410 may be designed in consideration of this part. According to an exemplary embodiment of the present invention, the third resistor R ₃ connected in series with the electrode unit 402a may be referred to as a second resistor unit.

When there is a measurement of the skin condition, the controller 410 may receive, for example, a skin voltage received through the electrode unit 402a. For example, the controller 410 may receive the skin voltage from the ADC terminal when the ADC is configured in the chip. Therefore, the ADC in the original chip digitally converts the received skin voltage as described above to generate binary bit information in the form of machine language. The control circuit in the control unit 410 recognizes the binary bit information to determine the skin condition.

Further, the control unit 410 processes the data converted through the ADC, that is, the first data through the signal processing unit, for example, low pass to generate the second data, and determines the measured skin condition through the generated second data. You can do it.

The controller 410 may classify the skin condition, for example, the degree of drying in stages, and specify bit information by matching each step, and preset the level, that is, information for spraying the active ingredient on the user's skin by matching the specified bit information. Can be. To this end, the control unit 410 designates the driest state as 1111, which is 4-bit information, and controls the cartridge power unit 420 in accordance with this to adjust the input amount of the active ingredient. In other words, the above bit information may be a control value of a motor included in the cartridge power unit 420.

Accordingly, when it is determined that the skin voltage measured by the electrode unit 402a is the dryest state, the controller 410 analyzes the ADC and the low-passed data and confirms that it is 1111. It can be seen that control the cartridge power unit 420 in a state (or corresponding) to match. For example, when using a low frequency of a fixed frequency, the control unit 410 increases the amount of active ingredients injected from the cartridge by increasing the speed of the motor of the cartridge power unit 420 when the degree of drying is severe as a result of skin condition measurement. . When the dryness decreases as a result of the measurement of the skin condition, again, the motor of the cartridge power unit 420 is controlled in the opposite direction to reduce the amount of the active ingredient sprayed from the cartridge. On the other hand, the control unit 410 reduces the dose of the drug and applies a high voltage to efficiently absorb the drug when the skin condition is dry from the measured skin resistance value when the multi-frequency low voltage determined according to the active ingredient 111 is used. It will be possible to reshape the skin so that it can. Therefore, the direction and speed of the above motor may be properly operated under the control of the controller 410. In this case, the motor may include a DC motor free of control of speed and direction, and furthermore, a step motor.

The cartridge power unit 420 may include a motor driver and a motor for driving the cartridge. As mentioned above, since the motor driving unit may correspond to a kind of sub control unit, the motor driving unit may receive a control value necessary for motor control from the (main) control unit 410 when the sub control unit is configured to drive the motor accordingly. If the sub control unit is not included, the motor may be directly controlled by the control unit 410. In the embodiment of the present invention, in consideration of the manufacturing cost, it is preferable not to include the sub controller. In this case, the cartridge power unit 420 may be a motor.

In addition, the cartridge power unit 420 may further include a housing of the cartridge. When the cartridge is accommodated in the accommodating portion, the amount of the active ingredient injected from the cartridge by the driving of the motor may be adjusted to be injected into the user's skin.

For convenience of description, referring to FIG. 5 together with FIG. 1, the skin care device 100 according to an embodiment of the present invention generates a high voltage and a low voltage of a predetermined size for use in skin stimulation of a user, and generates a low voltage frequency. To change (S500). To this end, the skin care device 100 may use the reference voltage information required for voltage generation. For example, the skin care device 100 generates reference voltage information by measuring a resistance sensed through an electrode exposed to ambient air during initial driving. Then, the magnitude of the high voltage may be determined based on the reference voltage information, and the high voltage may be generated based on the determined magnitude information. In addition, after a certain time elapses, that is, after the skin passage is formed by the high voltage, the voltage is changed to the low voltage. Of course, in this process, the skin care device 100 can be changed to a low voltage according to the measurement result by inputting the active ingredient and measuring the skin condition at the time of providing a high voltage, it is not particularly limited to any one operation .

In addition, the skin care apparatus 100 controls the change of the frequency of the low voltage according to the skin condition (or the drug determined according to the skin condition) of the user, and generates skin information related to the skin condition (S510). For example, after the skin passage is formed, the skin care device 100 may spray the active ingredient on the user's skin while changing to a low voltage having a predetermined size. A low voltage of a predetermined size having a predetermined frequency stimulates the skin and simultaneously sprays the active ingredient on the skin. As such, skin information for driving the motor may be generated to be used to spray the active ingredient on the skin. Thereafter, the skin care device 100 measures the skin condition by spraying the active ingredient after a predetermined time or at a predetermined time to generate skin information again based on the measured skin condition.

Subsequently, the skin care apparatus 100 adjusts the active ingredient corresponding to the changed frequency into the user's skin based on the generated skin information (S520). More specifically, the skin care device 100 forms a skin passage using, for example, a high voltage, and when the skin passage is formed, changes to a low voltage and outputs a certain amount of active ingredient to the user's skin. Then, after a certain time, the skin condition can be measured and the frequency of the low voltage can be changed and the amount of the active ingredient can be adjusted according to the measured skin condition.

Since this process describes a general operation process of the skin care device 100, more details will be described with reference to FIG.

6 is a flowchart illustrating a driving process of a skin care apparatus according to another exemplary embodiment of the present invention. For convenience of explanation, the following description will be made from the viewpoint of the controller.

Referring to FIG. 6 together with FIG. 4, the skin care apparatus 100 ′ according to another embodiment of the present invention controls to output a high voltage for forming a skin passage on the skin of the user (S600). The magnitude and frequency of this high voltage is determined at a maximum of 500 Vpp as mentioned above and a frequency of 3 Hz may be desirable. The pulse generator of the skin care apparatus 100 ′ may output a positive voltage and a negative voltage of the electroporation.

When the high voltage is output as described above, the skin care apparatus 100 ′ may measure the skin voltage due to skin resistance through the electrode part to determine whether a passage is formed in the skin by the output high voltage.

Then, when the skin passage is formed, the skin care device 100 determines whether the effective ingredient (or drug) is efficiently injected into the corresponding skin voltage value. If the effective ingredient is efficiently injected, the cartridge power unit 420 increases the speed in the direction in which the existing motor is driven to increase the input amount of the active ingredient. If the effective ingredient is not injected efficiently, the cartridge power unit 420 increases the speed in the opposite direction in which the existing motor is driven, thereby reducing the input amount of the active ingredient.

In this process, if the skin care device 100 ′ is in a state in which a low voltage pulse is to be applied after the high voltage pulse, the skin care device 100 ′ outputs a low voltage pulse such as a maximum voltage of 50 Vpp and a frequency of 1 Hz to 40 Hz to the pulse generator 401 (S610). ).

Thereafter, the skin care device 100 ′ continuously adjusts the output amount of the active ingredient according to the skin voltage measured through the voltage divider 402 (S620).

Up to now, the embodiment of the present invention has been described by exemplifying the operation process of the skin care device (100, 100 ') in two forms. In other words, the first form was a high voltage output to form the skin passage, the low voltage change output, the active ingredient input and skin resistance measurement, the low voltage frequency change output, the active ingredient input control by the operation of the skin passage is formed. However, this process may be in other forms. In the second case, for example, a high voltage output, an active ingredient input, a skin voltage measurement, a low voltage output, a skin voltage measurement, a low voltage frequency change output, and an active ingredient input control to form a skin passage may be formed. Therefore, this is particularly effective in the above operation in the embodiment of the present invention because it is efficient to operate the skin care device (100, 100 ') in any order, that is, the efficiency can be measured by various experiments. It will not be limited.
