Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art to which the present invention pertains can easily practice. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. In the drawings, parts not related to the description are omitted in order to clearly describe the present invention, and the same reference numerals are added to the same or similar elements throughout the specification.

The iontophoresis device 100 according to an embodiment of the present invention includes a power supply unit 110, a pair of electrodes 121 and 122 and a control unit 130 as illustrated in FIG. 1.

The pair of electrodes 121 and 122 are intended to increase skin penetration of ionic drugs or active ingredients by changing the electrical environment of the skin by generating a potential difference on the skin of the user when power is applied.

That is, the pair of electrodes 121 and 122 are for realizing the function of iontophoresis. When a current is applied to the user's skin using the power supplied through the power supply unit 110, the user's skin and Ion movement is generated by the pair of electrodes 121 and 122 forming a closed circuit. Here, the power supply unit 110 may be a known battery.

For example, when an ionic drug or an active ingredient is applied to the user's skin and the pair of electrodes 121 and 122 are brought into contact with the user's skin, when a current is applied to the pair of electrodes 121 and 122, the user's skin is applied. By ionizing the ionic drug or active ingredient applied to the ionic drug or active ingredient easily passes through the mucous membrane of the skin, the effect of ion introduction into the skin tissue occurs.

At this time, when a current flows through the user's skin using the power supplied from the power supply unit 110, the amount of current flowing through the user's skin changes according to the user's skin condition. Accordingly, even when the same voltage is applied to the pair of electrodes 121 and 122, the intensity of the electrical stimulation felt by the user also varies according to the user's skin condition.

This may vary in the size of the skin resistance according to the content of moisture contained in the user's skin or the user's skin thickness, and the thickness of the ionic drug or active ingredient applied to the user's skin surface for iontoresis function. Because it can vary.

For example, even if a voltage of the same magnitude is applied to the electrodes 121 and 122, if the user's skin is dry with a low moisture content or the user's skin is thick, the user's skin is wet with a high moisture content or the user's skin Since the skin resistance is relatively increased as compared to the thin case, the amount of current flowing through the user's skin is small, so the intensity of the electrical stimulation felt by the user is weak, and when the user's skin is moist with a lot of moisture or the user's skin is thin Since the skin resistance is relatively reduced, the amount of current flowing through the user's skin increases, so the intensity of the electrical stimulation felt by the user is relatively strong.

In addition, even when a voltage of the same magnitude is applied to the electrodes 121 and 122, when the coating thickness of the ionic drug or active ingredient applied to the user's skin is thin, the ionic drug or active ingredient has a thick coating thickness compared to the ionic drug or active ingredient. Since the amount of current flowing through the drug or active ingredient is relatively reduced, the intensity of electric stimulation felt by the user is relatively weak compared to the case where the thickness of the ionic drug or active ingredient is thick, and the ionic drug applied to the user's skin When the coating thickness of the active ingredient is thick, the amount of current flowing through the ionic drug or the active ingredient is relatively increased, so that the intensity of the electrical stimulation felt by the user is relatively strong.

In the present invention, by adjusting the output values of any one of the voltage and current applied to the electrodes 121 and 122 according to the user's skin condition, the user can always feel the electrical stimulation of a constant intensity regardless of the skin condition.

Here, the factors determining the skin condition of the user include the moisture content of the user's skin surface, the thickness of the user's skin in contact with the electrodes 121 and 122, the presence or absence of an ionic drug or active ingredient, and the application of the ionic drug or active ingredient It may be at least one of thickness.

In one example, the output value can be adjusted by changing any one of the magnitude of the voltage applied to the electrodes 121 and 122, the magnitude of the current, and the duty ratio (b/a) of the pulse current, and when the power is applied, the pair of Any of the magnitude of the voltage applied to the electrodes 121 and 122, the magnitude of the current, and the duty ratio of the pulse current based on the variation of the voltage value or the variation of the current value that varies depending on the skin condition of the user in contact with the electrodes 121 and 122 One can be variable.

To this end, the control unit 130 includes a sensing unit 131 for measuring a user's skin condition, and an integrated control unit 133 for determining a user's skin condition measured by the sensing unit 131 and controlling overall operation. And it may include an output generating unit 132 for varying the output value according to the signal output from the integrated control unit 133.

Here, the integrated control unit 133 may calculate an output value output from the output generation unit 132 based on a change amount of a voltage value or a change amount of a current value that is changed by the skin condition of the user.

In this case, the sensing unit 131 may check whether the pair of electrodes 121 and 122 contact the user's skin based on the magnitude of the voltage or current value measured between the pair of electrodes 121 and 122.

For example, in the state where the pair of electrodes 121 and 122 and the skin are not in contact, the resistance is infinite when power is applied, so no flow of current occurs and the voltage applied between the pair of electrodes 121 and 122 also has the same size as the applied voltage. You have.

However, in the state where the pair of electrodes 121 and 122 are in contact with the skin, a current of a predetermined size is measured or a voltage drop due to skin resistance occurs due to current flowing along the user's skin when power is applied.

Based on this principle, when the amount of change in the voltage value or the current value measured by the sensing unit 131 is greater than a predetermined size when the power is applied, the control unit 130 contacts the pair of electrodes 121 and 122 and the skin It is determined that the output value is applied to the pair of electrodes 121 and 122 through the output generator 132.

Here, the integrated control unit 133 is the amount of change in voltage or current value according to the user's skin condition is stored as a look-up table, so that the magnitude of the voltage, the magnitude of the current and the pulse output through the output generation unit 132 Any one of the duty ratios of the current may be changed, and the amount of change in the voltage value or current value stored in the look-up table is matched one-to-one with the amount of change in voltage value or the amount of current value measured through the sensing unit 131. It can be information.

For example, when the voltage applied between the pair of electrodes 121 and 122 is changed to 1 V or more, the controller 130 recognizes that the electrodes 121 and 122 and the user's skin are in contact, and the electrodes 121 and 122 A voltage of a predetermined size (eg, 25V) is applied to the voltage.

In this state, when the change in the voltage across the pair of electrodes 121 and 122 occurs according to the user's skin condition to be 1V or more, the control unit 130 displays the voltage value measured through the detection unit 131. Based on the amount of change, the integrated control unit 133 determines the user's skin condition, and a voltage between 20 to 25 V is output from the output generation unit 132 according to the determined user's skin condition or the skin is applied through a variable resistance. By controlling the amount of current flowing to the side, the user can feel the electrical stimulation of the same intensity.

That is, when the user's skin condition is humid and current can flow smoothly along the user's skin, the integrated control unit 133 reduces the magnitude of the output voltage output from the output generation unit 132 to 20V to reduce irritation. When the strength is weakened and the user's skin condition is dry and the amount of current flowing along the user's skin is relatively small, the integrated control unit 133 increases the magnitude of the output voltage output from the output generator 132 by 25V. To increase the intensity of the stimulus to increase to the user so that the user can always feel a stimulus of constant intensity regardless of the skin condition.

In another way, when the voltage applied between the pair of electrodes 121 and 122 is changed to 1 V or more, the controller 130 recognizes that the electrode 121 and 122 and the user's skin are in contact, and the electrodes 121 and 122 ), a pulse current having a duty ratio of 30% is applied.

In this state, when a change in voltage across the pair of electrodes 121 and 122 occurs according to a user's skin condition, the control unit 130 is based on the change amount of the voltage value measured through the detection unit 131. The integrated control unit 133 determines the user's skin condition, and controls the output generator 132 so that the duty ratio of the pulse current is output in the range of 25 to 35% according to the determined user's skin condition. It is also possible to feel the electrical stimulation of the same intensity.

That is, when the user's skin condition is humid and current can flow smoothly along the user's skin, the integrated control unit 133 reduces the duty ratio of the pulse current output from the output generator 132 to 25%. When the intensity of the stimulus is weakened and the skin condition of the user is dry and the amount of current flowing along the user's skin is relatively small, the duty of the pulse current output from the output generator 132 by the integrated controller 133 By increasing the rain to 35%, the intensity of the irritation is strengthened so that the user can always feel the irritation of a constant intensity regardless of the skin condition.

In addition, the iontophoresis device 100 according to the present invention is a voltage value through the sensing unit 131 even if the skin condition of the user changes due to the penetration of the ionic drug or active ingredient applied to the user's skin. As the amount of change is measured in real time, the integrated control unit 133 controls the output generation unit 132 to output an output value suitable for the user's current skin condition. Accordingly, the user can always feel the electrical stimulation of uniform intensity during the operation time of the iontophoresis device 100.

Here, the voltage applied to adjust the intensity of the electrical stimulation felt by the user is illustrated as being changed in the range of 23 to 25 V, or the duty ratio of the pulse current is changed in the range of 25 to 35%, but is not limited thereto. It is revealed that it can be changed to various ranges depending on conditions.

On the other hand, in the iontophoresis device 100 according to the present invention, the voltage applied to the electrodes 121 and 122 may be always applied in the same size when driving through operation of the switch unit 140, but the electrodes 121 and 122 may be applied. The voltage applied to the pair of electrodes 121 and 122 to confirm whether the skin is in contact with the skin is the pair of electrodes 121 and 122 to penetrate the skin with the ionic drug or active ingredient applied to the user's skin. A voltage having a size relatively smaller than the voltage applied to may be applied.

That is, in the initial state in which the iontophoresis device 100 is driven through the operation of the switch unit 140, a small voltage of approximately 10V may be applied to check whether the electrodes 121 and 122 are in contact with the skin. , In a state in which the contact between the electrodes 121 and 122 and the skin is confirmed, the pair of electrodes 121 and 122 is relatively large so that the ionic drug or active ingredient applied to the user's skin can smoothly penetrate the skin. A voltage of 25V can be applied. This is to increase the use time of the power supply unit 110 by preventing unnecessary power consumption in the standby state.

In addition, the iontophoresis device 100 according to the present invention may be changed to a plurality of output modes having output values of different ranges through manipulation of the switch unit 140 of the user. For example, the switch unit 140 may be implemented with at least one button 142 capable of a user's pressing operation, and a strong mode in which the intensity of electric stimulation is different depending on the number of pressing times of the button 142, general The mode can be changed to the weak mode.

Specifically, when the user drives the control unit 130 in a strong mode through the operation of the button 142, the magnitude of the voltage applied to the pair of electrodes 121 and 122 is 35 to 35 depending on the user's skin condition. It can be varied in the range of 45V, when driving in the normal mode, the magnitude of the voltage applied to the pair of electrodes 121 and 122 can be varied in the range of 25 to 35V according to the user's skin condition, and weak mode In the case of driving with, the magnitude of the voltage applied to the pair of electrodes 121 and 122 may be varied in the range of 15 to 25V according to the user's skin condition.

As another example, when the user controls the controller 130 to operate in a strong mode through the operation of the button 142, the duty ratio of the pulse current applied to the pair of electrodes 121 and 122 depends on the user's skin condition. It may be varied in the range of 60 to 80%, and when driving in the normal mode, the duty ratio of the pulse current applied to the pair of electrodes 121 and 122 may vary in the range of 40 to 60% according to the user's skin condition. When driving in the weak mode, the duty ratio of the pulse current applied to the pair of electrodes 121 and 122 may be varied in a range of 20 to 40% according to the user's skin condition (see FIG. 3).

Accordingly, the user can select one of the strong mode, the normal mode and the weak mode through the operation of the button 142 to select the intensity of electrical stimulation applied to the skin, and the selected output mode is the user's By adjusting the output value within a predetermined range according to the skin condition, the user can feel a uniform electric stimulation intensity at a desired intensity regardless of the skin condition.

In one example, when the iontophoresis device 100 according to the present invention is operated in a strong mode, the user adjusts the magnitude of the voltage applied to the electrodes 121 and 122 according to the current skin condition, thereby approximating the normal skin condition. It is possible to feel the intensity of electric stimulation to which a voltage of 40 V is applied, and even if the condition of the skin is changed through the penetration of an ionic drug or an active ingredient, the magnitude of the voltage applied to the electrodes 121 and 122 in accordance with the changed skin condition By being regulated, it is possible to feel the intensity of electrical stimulation to which a voltage of approximately 40 V is applied in a normal skin condition.

As described above, the iontophoresis device 100 according to the present invention generates at least one light source 240 that irradiates the skin side of a user by generating light having a predetermined wavelength band as shown in FIGS. 4 and 5. It can be applied to the skin beauty device 200, including.

Through this, in addition to the skin improvement effect using the light source 240, the skin penetration effect of the ionic drug or active ingredient through the iontophoresis device 100 can be simultaneously obtained.

For example, the skin beauty device 200 to which the iontophoresis device 100 according to the present invention is applied may include a case part 210, a frame part 220, and a cap part 230 (see FIG. 5). .

The case portion 210 forms an overall appearance, and accommodates various components such as a known battery that serves as a light source 240, a circuit board 242, and a power supply unit 110 therein to protect it from an external environment. A body 211 may be included, and a pair of electrodes 121 and 122 for realizing the function of iontophoresis on one side of the body 211 may be provided to the outside (see FIG. 4 ). .

In addition, the case unit 210 may protect the light source 240 from the external environment and a light-transmitting cover 212 for protecting the user's eyes may be disposed on the front side of the light source 240.

At this time, the skin beauty device 200 increases the convenience of assembly and minimizes the pinching of foreign substances due to contact with the user's skin during the use process, the body 211, a pair of electrodes 121, 122 and a light-transmitting cover ( 212) may be integrally formed.

On the other hand, the pair of electrodes 121 and 122 for the iontophoresis function, the light source 240 is mounted by a pair of elastic members 243 contacting each other when the cap portion 230 and the case portion 210 are coupled. The circuit board 242 can be electrically connected to each other.

Accordingly, the electrodes 121 and 122 apply a current to the user's body using power supplied from a battery, so that the user's skin and a pair of electrodes 121 and 122 can form a closed circuit.

The cap portion 230 may be coupled to the lower side of the case portion 210 to seal the lower side of the opened interior space.

The cap portion 230 may be detachably coupled to the case portion 210.

In this case, the cap part 230 may be detachably coupled to the frame part 220 to which the circuit board 242 on which the light source 240 is mounted is fixed, and the main circuit board 134 constituting the controller 130. ) May be fixed to the cap part 230, and the circuit board 144 constituting the switch part 140 for sensing a user's manipulation signal may be fixed.

Here, a battery that provides driving power may be disposed on one surface of the main circuit board 134, and the circuit board 242 and the switch unit on which the battery, the main circuit board 134, and the light source 240 are mounted ( The circuit boards 144 constituting 140 may be electrically connected to each other.

Meanwhile, at least one light source 240 mounted on the circuit board 242 generates light having a predetermined wavelength band and irradiates it toward the user's skin to obtain a beneficial effect according to the wavelength of light.

At this time, the light source 240 may be provided to enable irradiation of light in different wavelength bands. In one example, the light source 240 may be provided with a plurality of light sources 140 having light in different wavelength bands, but a single light source 240 may include a plurality of light emitting elements irradiating light in different wavelength bands ( 241a, 241b, 241c) may be formed integrally (see FIG. 5).

For example, the plurality of light emitting devices may be integrally formed with three chips that emit light of different wavelength bands in one chip.

In this case, as the light source, two or more light sources irradiating light of different wavelength bands may be appropriately used.

In addition, the light source may be lighted continuously or lighted and lighted off may be repeated.

On the other hand, when the light source 240 includes a plurality of light emitting elements that emit light of different wavelength bands, selection of the light emission mode of the light source is performed by the switch unit 140 provided on one side of the case unit 210. It can be done through manipulation.
