In the case of contact, the resistance value of the corresponding contact member 420 is detected, and the sheet member 400 can be identified based on the detected resistance value.

[55] For example, when the resistance value of the contact member 420 is detected in the show range, the skin care mode determination unit (0) identifies that the sheet member 400 is a dedicated sheet member used in the nutrition supply mode. When the resistance value of the contact member 420 is detected in the range of: 8, the skin care mode determination unit (0) can identify that the sheet member 400 is a dedicated sheet member used in the lifting mode.

For example, if the sheet member 400 is identified as being a sheet member exclusively for the nutrition supply mode, the skin management mode can be determined as the nutrition supply mode. And, if the sheet member 400 is identified as being a seat member exclusively for the lifting mode, the skin care mode can be determined as the lifting mode.

[6 In this embodiment, the control unit 100 is based on at least one of the skin care mode and the user's skin moisture, the time to apply a current to the conductive pattern (four 0) of the sheet member 400, 2020/145634 1»（：1^1{2020/000283

8 At least one of the intensity of the light source emitted from the plurality of light emitting materials 320, the color of the light source, and the light emission time can be controlled differently.

6 is a light-emitting material and a light-emitting material according to the skin care mode according to an embodiment of the present disclosure

A table is shown for explaining a specific example of controlling the output of the electrode member. Referring to FIG. 6, each skin care mode is divided into three stages, and the total execution time of the skin care mode may be set to 12 minutes, This is only one embodiment and may not be limited thereto. The skin care mode may include a cleansing mode, a softening mode, a nutrition supply mode, a lifting mode, and a whitening mode.

[62] For example, in the case of the total care mode, in the first step, the electrode part 500 is

Turn on, light-emitting the color of the light-emitting material 320 in red, and in the second step, turn on the electrode part 500 for 5 minutes, and emit the color of the light-emitting material 320 in yellow,

In step 3, the electrode part 500 is turned off for 2 minutes, and the color of the light-emitting material 320 may be emitted in blue.

7 is an exemplary view showing the concept of executing the iontophoretic function on the skin by controlling the output of the electrode unit according to the skin management mode according to an embodiment of the present disclosure.

Referring to FIG. 7, when current is supplied to the electrode unit 500, the electrode unit 500 and

Since the hydrogel component contained in the sheet member 400 is ionized through the conductive pattern 420 electrically contacted to the electrode part 500 and penetrates the user's skin, the absorption of the hydrogel component from the skin cells can be maximized. .

Specifically, the control unit 100 (as shown in the book through the electrode unit 500)

It is possible to execute a cleansing mode in which anion-bearing wastes are adsorbed by using positive ions, and (as shown in the figure, the positive and negative ions are

By applying stimulation by interaction, it is possible to execute a softening mode that has the effect of tidying the skin.(As shown in 0, through the electrode part 500, the electrode uses the repulsive force between the same ions, It is possible to perform a nutrient supply mode that allows the gel component to penetrate into the skin, and as shown in (I)), the electrode unit 500 is used to provide stimulation to the skin through the generation of microcurrents by positive and negative ions. You can run the mode.

On the other hand, the control unit 100 is the skin of the user classified by the skin moisture measurement unit 120

Based on the moisture level, the light-emitting materials and skin care modes disclosed in Fig.6

The output of the electrode member can be further changed.

[67] For example, when the skin management mode is a total care mode, and the skin moisture level is at a lower level, the turn-off execution setting for the electrode unit 500 corresponding to the third step of the total care mode shown in FIG. By changing to the turn-on execution, the value of the microcurrent output from the electrode unit 500 can be relatively increased. In addition, the control unit 100 emits light in the setting of the skin care mode shown in Fig. 6 even according to the level of the skin moisture level. At least one of the material's color, luminous intensity, luminescence time, and microcurrent supply time can be further changed. 2020/145634 1»（：1^1{2020/000283

[68] The mask device of this disclosure stores power to the capacitance 50 in order to deliver a fine current to the skin, and discharges the stored power to the electrode member 500. Even when the skin care mode is switched, the capacitance ( 50), the converted

When starting the skin care mode, the power remaining in the capacitance causes an instantaneous overcurrent to occur, which may cause discomfort such as irritation to the user's skin.

[69] In order to prevent such a phenomenon, in one embodiment of the present disclosure, switching

The control unit 150 controls the switching unit 60 provided between the electrode unit 500, the capacitance 50, and the ground (GND), thereby selectively intercepting the power discharged from the capacitance 50 to the electrode unit 500 can do.

[7, specifically, when the skin management mode is switched, the switching control unit 150

After reset by connecting the capacitance 60 to ground (GND) through the switching unit 60, the overcurrent can be prevented by connecting the capacitance 60 to the electrode unit 500 again.

1] In one embodiment, when the change in the resistance value of the contact member 420 is measured even while the mask device 1000 is being executed, the control unit 100 identifies the sheet member again based on the changed resistance value, and the identification result Recognizes the changed sheet member based on

You can decide to switch to the skin care mode mapped to the sheet member.

2] For example, when the control unit 100 detects a change in the resistance value of the contact member 420 in a state in which the lifting mode exclusive seat member is attached to the mask device 1000 and the lifting mode is being executed, it is based on the changed resistance value. By doing so, it is possible to identify the sheet member for exclusive use of another mode newly attached to the mask device 1000. If the sheet member for exclusive use of the other mode is identified as a feeding mode sheet member, the control unit 100 first resets the capacitance 60. After that, it is possible to execute the driving of the light emitting material and the electrode member preset in response to the nutrition supply mode. In other words, the control unit 100 grounds all the power remaining in the capacitance 60 before executing the nutrition supply mode. Thereafter, the power to the capacitance 60 can be re-supplied to execute the nutrient supply mode. At this time, as described above, the control unit 100 further considers the user's skin moisture,

The output of the electrode member can be adjusted again.

3] As another embodiment of the present disclosure, the control unit 100 may control the driving of the mask device 1000 according to whether or not the sheet member is attached to the mask device 1000. In other words, the control unit 100 It can be determined whether the user is wearing the mask device 1000 by attaching the sheet member, or whether the mask device 1000 is directly worn on the skin without attaching the sheet member. For this purpose, the control unit 100 is an electrode unit. The resistance value of the material contacted with 500 may be measured, and based on the measured resistance value, it may be determined whether the material contacted with the electrode part 500 is a sheet member or a skin. The control unit 100 determines whether the user is wearing the mask device 1000 by attaching the sheet member, or whether the mask device 1000 is worn without attaching the sheet member. Depending on whether it is in a state, it is possible to control the output of at least one of the light emitting material and the electrode member.

4] In one embodiment, depending on whether the seat member is worn, the control unit 100 is the same

Even in the skin care mode, by changing at least one of the luminescent material and electrode

Different outputs are possible. For how to control at least one of the light-emitting material and the electrode member, you can refer to the above information, so detailed explanations will be omitted.
