The identification tag 22 is a cooling condition of the thermoelectric module 30 (cooling condition of the first main surface 31 ) corresponding to identification data of the functional material 21 accommodated in the contact layer 20 on which the identification tag 22 is disposed. ) can have data about For example, when the identification tag 22 is recognized by the tag recognition module 74 , the controller 50 determines the cooling condition (first main surface) of the thermoelectric module 30 corresponding to identification data of the identification tag 22 . It is possible to obtain data regarding the cooling condition of (31)), and control the thermoelectric module 30 according to the obtained cooling condition.

At least one thermoelectric module 30 may be formed to generate heat or absorb heat as power is applied. For example, the at least one thermoelectric module 30 may apply cooling heat to the user's skin through the contact layer 20 as power is applied.

Thermoelectric module uses thermoelectric effect such as Seeback effect or Peltier effect to perform thermoelectric operation such as power generation operation using temperature difference or heating/cooling operation using electric energy. It may mean a module that executes. In general, most thermoelectric modules are provided in the form of electrically connecting a thermoelectric element composed of an NP semiconductor to a flat substrate made of a ceramic material, but the thermoelectric module 30 in the present specification may include a thermoelectric module having flexibility. can The thermoelectric element may be a device that induces a thermoelectric effect such as a Seebeck effect or a Peltier effect. Basically, the thermoelectric element may include heterogeneous materials constituting a thermoelectric couple that induces a thermoelectric effect. The thermocouple may generate a temperature difference when electrical energy is applied, and conversely, may produce electrical energy when a temperature difference is applied. An example of the thermoelectric element is a pair of bismuth and antimony. Also, a pair of mainly an N-type semiconductor and a P-type semiconductor may be used as a thermoelectric element.

The at least one thermoelectric module 30 has two main surfaces including a first main surface 31 disposed in contact with an upper portion of the contact layer 20 and a second main surface 32 positioned on the opposite side of the first main surface 31 . can have For example, the at least one thermoelectric module 30 includes a first main surface 31 disposed in contact with an upper portion of the contact layer 20 and a second main surface 32 positioned on the opposite side of the first main surface 31 . It has two main surfaces 31 and 32, and as power is applied, the first main surface 31 is cooled to apply cooling heat to the user's skin through the contact layer 20 .

The pair of main surfaces 31 and 32 may include a first main surface 31 and a second main surface 32 spaced apart from each other to face each other. The first main surface 31 and the second main surface 32 may support a thermoelectric element or an electrode disposed therebetween. In addition, the first and second main surfaces 31 and 32 may function to protect the thermoelectric element or electrode therein from the outside.

In addition, the pair of main surfaces 31 and 32 may be made of a material that easily conducts heat. For example, the pair of main surfaces 31 and 32 may be a substrate made of a copper material.

In addition, at least one thermoelectric module 30 according to an embodiment of the present specification may be provided as a flexible thermoelectric module 30 having flexibility. The mask 10 may be manufactured in a complicated shape (for example, a shape corresponding to the face) such as having a curve in order to adhere well to the user's face. When the flexible thermoelectric module 30 is used, manufacturing difficulties can be reduced, and It is possible to provide a mask 10 having a shape that is more closely attached to the face.

To this end, the pair of main surfaces 31 and 32 and the inside of the thermoelectric module 30 may be made of a flexible material. For example, the pair of main surfaces 31 and 32 may be a thin polyimide (PI) film. The polyimide film has excellent flexibility and, although not high in thermal conductivity, may be advantageous in heat conduction because it can be manufactured to a thin thickness.

Since the skin characteristics of a plurality of regions constituting a human body part are different, it is necessary to perform different cooling for each region of the body part. For example, conditions under which skin damage or suppression of pigmentation occurs may be different for each of the plurality of regions constituting the facial part. Therefore, according to an embodiment of the present specification, the plurality of thermoelectric modules 30 may be classified into a plurality of thermoelectric module groups 33 , and the plurality of thermoelectric module groups 33 are independent of other thermoelectric module groups 33 . may be controlled by the controller 50 . The thermoelectric module group 33 may include at least one thermoelectric module 30 . Here, each of the plurality of thermoelectric module groups 33 may be divided by regions of the user's face.

4 is a view illustrating thermoelectric modules disposed inside a mask according to an embodiment of the present specification.

Referring to FIG. 4 , the plurality of thermoelectric modules 30 may be classified into a plurality of thermoelectric module groups 33a, 33b, 33c, and 33d for each area of the user's face.

Each of the thermoelectric module groups 33a, 33b, 33c, and 33d may be divided according to the area of the face of the disposed user. For example, each of the thermoelectric module groups 33a, 33b, 33c, and 33d may be divided into regions having a similar temperature among regions forming the user's face.

Unlike the internal temperature of the human skin, the temperature of about 32-34°C is distributed instead of 36-37°C, and the temperature distribution in each area of the human face differs from person to person. The temperature distribution is symmetrical in the shape of blood vessels, and it can be divided into several regions with similar temperatures depending on the temperature. The forehead area has a lot of blood vessels and the heat cannot escape because of the hair, so the temperature is high, and the chin area is hot because there are many blood vessels around it. The area on either side of the nose is also relatively high in blood vessels, so the temperature is relatively low because there are not many blood vessels in the cheek area. The nose area is cooler than other parts of the face due to the breathing of outside air. In other words, in general, in the face of a person, the skin temperature is measured to be high in the forehead area, chin area, both sides of the nose, cheek area, and nose area, and depending on the temperature, the forehead area, the chin area, the sides of the nose, It can be divided into a cheek area and a nose area.

Therefore, according to an exemplary embodiment of the present specification, the plurality of thermoelectric modules 30 includes the first thermoelectric module group 33a disposed in the forehead region and the chin region, and the second thermoelectric module group 33b disposed in both sides of the nose. It may be divided into a third thermoelectric module group 33c disposed in the cheek region and a fourth thermoelectric module group 33d disposed in the nose region.

The plurality of thermoelectric module groups 33a, 33b, 33c, and 33d may be controlled by the controller 50 independently of other thermoelectric module groups 33a, 33b, 33c, and 33d. For example, the controller 50 controls the plurality of thermoelectric modules 30 independently of on/off, cooling time, cooling temperature, operation mode, etc. for each of the plurality of thermoelectric module groups 33a, 33b, 33c, and 33d. can do.

The plurality of thermoelectric module groups 33a, 33b, 33c, and 33d may be cooled to a lower temperature as the thermoelectric module group 33 disposed in a region having a higher face temperature. That is, the controller 50 includes a plurality of thermoelectric module groups 33a, 33b, 33c, 33d so that the first main surface 31 is cooled to a lower temperature as the thermoelectric module group 33 disposed in the region where the temperature of the face is high. can be controlled.

For example, in the first thermoelectric module group 33a disposed in the forehead and chin regions where the temperature is high, the first main surface 31 may be cooled to -15°C, and the first thermoelectric module group 33a disposed in the nose region where the temperature is low. The first main surface 31 of the 4 thermoelectric module group 33d may be cooled to 0°C.

In addition, the cooling duration of the plurality of thermoelectric module groups 33a, 33b, 33c, and 33d may be longer as the thermoelectric module group 33 disposed in a region having a high face temperature. That is, the controller 50 controls the plurality of thermoelectric module groups 33a, 33b, 33c, and 33d so that the first main surface 31 is cooled for a longer period of time as the thermoelectric module group 33 disposed in the region where the temperature of the face is high. can be controlled

For example, the first thermoelectric module group 33a disposed in the forehead and chin regions where the temperature is high may be cooled such that the cooling duration is 120 seconds, and the fourth thermoelectric module group is disposed in the nose region where the temperature is low. (33d) may be cooled such that the duration of cooling is 60 seconds.

However, the above-described thermoelectric module group 33 is not limited thereto, and the thermoelectric module group 33 may be more or less thermoelectric module groups 33 than the plurality of thermoelectric module groups 33 described above, and each thermoelectric module The group 33 is not limited to the above description.

In addition, according to an exemplary embodiment of the present specification, the at least one thermoelectric module 30 may be disposed by adjusting the separation distance when disposed inside the mask 10 .

5 shows a state in which the cooling heat of the mask according to an embodiment of the present specification is transmitted to the skin.

The cooling heat of the first main surface 31 of the thermoelectric module 30 is applied to the user's skin through the contact layer 20 . When cold heat applied to the skin is transferred from the skin, it is transferred in the form of a sphere within the skin.

Referring to FIG. 5 , it can be seen that a hemisphere for transferring cold heat is formed on the skin around the thermoelectric module 30 . That is, the temperature of the skin at the point where the thermoelectric module 30 is disposed and the temperature of the skin at the point where the thermoelectric module 30 is not disposed are different.

When a plurality of thermoelectric modules 30-1, 30-2, and 30-3 are disposed on the mask 10, if the separation distance between each thermoelectric module 30-1, 30-2, 30-3 is too long, each thermoelectric module In a portion between the modules 30-1, 30-2, and 30-3, cooling and heat may not be properly transmitted and partial whitening may occur, resulting in uneven skin tone. When a plurality of thermoelectric modules 30-1, 30-2, 30-3 are disposed to prevent partial whitening, the separation distance between each thermoelectric module 30-1, 30-2, 30-3 may be adjusted. can

The plurality of thermoelectric modules (30-1, 30-2, 30-3) are spaced apart so that cooling heat can be applied to an intermediate point between the respective thermoelectric modules (30-1, 30-2, 30-3) when cooling. can be placed as For example, the plurality of thermoelectric modules 30-1, 30-2, 30-3 may have a separation distance in the range of 1 mm to 50 mm between the respective thermoelectric modules 30-1, 30-2, 30-3. can be placed.

The plurality of thermoelectric modules (30-1, 30-2, 30-3) have a skin temperature at an intermediate point between each thermoelectric module (30-1, 30-2, 30-3) and the thermoelectric module (30-1) during cooling. , 30-2, 30-3) may be disposed based on the skin temperature of the disposed point.

When the plurality of thermoelectric modules 30-1, 30-2, and 30-3 are cooled, the difference between the skin temperature at the midpoint between the thermoelectric modules 30 and the skin temperature at the point where the thermoelectric module 30 is disposed It may be arranged at a separation distance to be below a set temperature. For example, the first thermoelectric module 30-1 may have a skin temperature at a midpoint of the second thermoelectric module 30-2 and a point at which each thermoelectric module 30-1, 30-2 is disposed. They can be placed with a separation distance such that the difference in skin temperature is 10°C or less.

As is well known, when heat absorption occurs on one surface of a thermoelectric element, heat is generated on the other surface, and vice versa. For example, when heat absorption occurs on the first main surface 31 of the thermoelectric module 30 to cool the user's skin, heat is generated on the second main surface 32 side of the thermoelectric module 30, and the second main surface 32 ), when the heat generated from the side is not well dissipated, the amount of power applied to the mask 10 may increase as well as the cooling efficiency on the first main surface 31 may be reduced. Accordingly, the mask 10 may include a heat dissipation layer 40 to receive and radiate heat generated when the first main surface 31 is cooled.

The heat dissipation layer 40 is disposed on the thermoelectric module 30 so as to be in contact with the second main surface 32 of the thermoelectric module 30 , and is generated when the first main surface 31 is cooled through the second main surface 32 . It can receive heat and dissipate heat. For example, the heat dissipation layer 40 is composed of a material having high specific heat or thermal conductivity, or a fluid circulator, a fan, etc. that exchange heat through a circulating fluid may be installed, and various heat dissipation means may be combined or installed. .

In addition, the heat dissipation layer 40 may be provided in a shape in which surfaces in contact with the outside of the heat dissipation layer 40 alternately protrude and protrude in a recessed and concave-convex structure to increase an area in contact with the outside to improve heat dissipation.

In addition, the heat dissipation layer 40 is independently configured and may be formed in a structure that can be replaced or detached.

In general, the temperature difference between the heat absorbing surface and the heat generating surface of the thermoelectric module is saturated between about 30 °C and 55 °C as power is applied. That is, when power is continuously applied to the thermoelectric module, the temperature difference between the heat absorbing surface and the heat generating surface of the thermoelectric module is maintained between about 30°C and 55°C. Therefore, when the temperature of the heat-generating surface of the thermoelectric module is too high, the temperature of the heat-absorbing surface of the thermoelectric module also rises, and the mask 10 may not be able to cool the user's skin to the target cooling temperature. The mask 10 has a first main surface 31 and a second main surface (31) so that the temperature difference between the heat absorbing surface and the heat generating surface is maintained at less than about 30 °C to 55 °C so that the thermoelectric module can be continuously used for cooling the user's skin. 32) may include a heat dissipation layer 40 that maintains a temperature difference between the two below a preset temperature (eg, 30°C to 55°C).

Accordingly, according to an embodiment of the present specification, the heat dissipation layer 40 is disposed on the thermoelectric module 30 to contact the second main surface 32 of the thermoelectric module 30 and is disposed on the first main surface 31 at a temperature and In order to maintain the temperature difference of the second main surface 32 below a preset temperature, heat generated when the first main surface 31 is cooled is transferred and absorbed through the second main surface 32, and latent heat at the melting point is removed. It may be provided as a phase change material heat dissipation layer 40a including a phase change material (PCM) that maintains a constant temperature of the second main surface 32 by using it.

A phase change material has a large latent heat, so it is a material that can store and release a large amount of energy during phase change. A substance that accumulates or releases heat through the process of changing from one state to another, such as from a solid to a liquid state, from a liquid to a solid state, etc. When the external temperature falls below the melting point of the phase change material, the phase change material is different A large amount of latent heat is released while changing, and when the external temperature rises above the intrinsic melting point of the phase change material, a large amount of latent heat is absorbed as the phase changes. Therefore, since the phase change material absorbs or releases a lot of heat as the state of the material changes, the temperature corresponding to the melting point can be maintained constant for a longer period of time than other materials. By using such a phase change material, the phase change material heat dissipation layer 40a maintains the temperature of the second main surface 32 at a constant temperature, thereby reducing the difference between the temperature of the first main surface 31 and the temperature of the second main surface 32 . It can be maintained below a preset temperature. Here, the preset temperature may be selected from an appropriate value in the range of 30 °C to 55 °C.

The phase change material heat dissipation layer 40a may include a phase change material having a melting point within a specific range in order to maintain the difference between the temperature of the first main surface 31 and the temperature of the second main surface 32 below a preset temperature. can For example, the phase change material heat dissipation layer 40a may include a phase change material having a melting point of -15°C to 40°C, such as _{C 12} H ₂₆ , C ₁₆ H ₃₄ , and C ₂₀ H _{42 .} .

In addition, the phase change material heat dissipation layer 40a has a phase change of mass determined based on the input power of the thermoelectric module 30 , the use time, the amount of heat absorbed by the first main surface 31 , and the latent heat at the melting point of the phase change material. material may be included.

For example, the mass G of the phase change material included in the phase change material heat dissipation layer 40a may be determined by Equation 1 below.

- Here, Q _C is the amount of heat absorbed by the first main surface 31 , P is the input power of the thermoelectric module 30 , t is the usage time of the thermoelectric module 30 , and ΔH is the latent heat at the melting point of the phase change material -

The heat absorption Q _C of the first main surface 31 may be defined as the amount of heat absorbed per time by the first main surface 31 of the thermoelectric module 30 .

For example, the heat absorption Qc of the first main surface 31 is 3000J/Sec, the input power P of the thermoelectric module 30 is 2.3W, the use time t of the thermoelectric module 30 is 40 seconds, the melting point of the phase change material When the latent heat of ΔH is 230 J/g, the mass (G) of the phase change material included in the phase change material heat dissipation layer 40a of the mask 10 is G=(3000+2.3) according to Equation 1 above. ) × 40 / 230 = 522.14 g.

It should be noted that the method of determining the mass of the phase change material included in the phase change material heat radiation source 40a is not limited to the above-described method and may be performed in various ways.

The vibration generating module 72 may be provided as, for example, a vibrator, a vibration motor, a haptic device, or the like.

In addition, the vibration generating module 72 may output a vibration for alleviating the user's pain while the user's skin is cooled. For example, the vibration generating module 72 may output vibration (eg, vibration massage) while cooling or heat is applied to the user's skin through the thermoelectric module 30 , and apply vibration to the user's skin.

The vibration generating module 72 decreases the cooling temperature of the first main surface 31 or the cooling time of the first main surface 31 as the intensity of the cooling heat applied to the user's skin through the thermoelectric module 30 is stronger (ie, the cooling temperature of the first main surface 31 is lower).

For example, the touch sensing module 73 may be disposed on the contact layer 20 .

The touch detection module 73 may generate a skin detection signal when detecting the user's skin. Alternatively, the touch sensing module 73 may generate a skin non-sensing signal when the user's skin is not detected.

The touch sensing module 73 may be used as a means for determining when the cooling of the first main surface 31 starts. For example, when the touch detection module 73 detects the user's skin, it generates a skin detection signal and sends the corresponding signal to the controller 50, and the controller 50 receives the skin detection signal when the first main surface 31 ) to start cooling the thermoelectric module 30 may be controlled.

(21) can be identified. For another example, the tag recognition module 74 recognizes the identification tag 22 and the cooling condition of the thermoelectric module 3 (cooling condition of the first main surface 31 ) corresponding to identification data of the identification tag 22 . ), the controller 50 may control the thermoelectric module 30 according to the cooling condition data.

However, it is not limited to the above-described configuration, and the controller 50 may be a controller 50 having more or fewer configurations than the configuration described above, and each configuration is not limited to the above description.

Hereinafter, a first embodiment in which the controller 50 controls the temperature of the first main surface 31 of the thermoelectric module 30 will be described.

<First embodiment>

10 is a graph illustrating a temperature change over time of a first main surface of the thermoelectric module according to the first embodiment of the present specification.

If the user's skin is cooled too much, skin damage may occur due to skin freezing, etc., and if the user's skin is cooled too weakly, pigmentation due to cooling of melanocytes may not be suppressed.

Therefore, the controller 50 according to an embodiment of the present specification operates the thermoelectric module 30 in a whitening mode in which the first main surface 31 suppresses pigmentation by melanocytes but is cooled under cooling conditions to prevent skin damage. can be controlled Referring to FIG. 10 , it can be seen that the whitening mode is performed in which the thermoelectric module 30 is controlled by the controller 50 and the first main surface 31 is cooled to a cooling temperature of 5°C for 120 seconds.

Hereinafter, the time during which the first main surface 31 is cooled in the whitening mode is referred to as the whitening time, the temperature of the first main surface 31 during the whitening mode is referred to as the whitening temperature, and the temperature of the first main surface 31 while the whitening mode is performed. The range of temperatures is referred to as the whitening temperature range.

The controller 50 may control the thermoelectric module 30 so that the first main surface 31 is cooled in a specific temperature range in order to prevent skin damage due to cooling while suppressing pigmentation caused by melanocytes on the user's skin. For example, in order for the user's skin to reach a target temperature at which pigmentation caused by melanocytes is suppressed, the controller 50 controls the first main surface 31 during a temperature range of -15°C to 15°C, which is a whitening temperature range. The thermoelectric module 30 may be controlled to be cooled to a temperature lower than the target temperature. This is that when the temperature of the first main surface 31 is too low, skin damage due to freezing of the skin tissue may occur, and when the temperature of the first main surface 31 is too high, the inhibitory effect of pigmentation by melanocytes may be low. because there is

Here, the target temperature may be a temperature of 4°C to 27°C. Because the skin whitening effect due to cooling of the skin increases as the temperature of the skin is kept low, the target temperature may be a temperature of 27°C or less for the skin whitening effect due to cooling of the skin to occur substantially. In addition, actual freezing of human skin tissue does not occur before the skin temperature is -4°C to -10°C, but when the skin temperature falls below 4°C, tissue damage is caused by ischemia and thrombus in small blood vessels. As this may occur, the target temperature may be a temperature above 4 °C to prevent skin damage due to cooling of the skin.

However, the cooling temperature of the first main surface 31 controlled by the controller 50 does not need to be limited to the above description, and the cooling temperature of the first main surface 31 is in a temperature range of -30 °C to 35 °C. It may be maintained in the circumstances, etc., depending on the circumstances. In addition, the target temperature is not necessarily limited to the above description, and the target temperature may vary depending on circumstances, such as being a temperature of -10°C to 35°C.

In addition, the controller 50 prevents skin damage due to cooling, but sets the whitening time, which is the time during which the cooling of the first main surface 31 continues to suppress pigmentation caused by melanocytes, the first time required for suppression of pigmentation. The thermoelectric module 30 may be controlled to be longer than the second time and shorter than the second time when skin damage occurs. For example, the controller 50 suppresses pigmentation caused by melanocytes, but the time for cooling the first main surface 31 to prevent damage to the skin is 5 seconds required for suppression of pigmentation, and damage to the skin occurs. It is possible to control the thermoelectric module 30 to be maintained between 300 seconds. For another example, the thermoelectric module 30 may be controlled so that the cooling time of the first main surface 31 is maintained between 5 seconds required for suppression of pigmentation and 900 seconds with the possibility of microscopic damage to the skin.

Here, the first time may mean the minimum time required for suppression of pigmentation due to cooling of melanocytes, and when the skin is cooled for a shorter time than the first time, sufficient cooling of melanocytes is not made, so that pigmentation is suppressed can't be For example, the first time period may be at least 5 seconds for a skin lightening effect due to cooling of the skin to substantially occur. However, the first time may vary depending on circumstances, such as at least 0.5 seconds in order to minimize the skin whitening effect due to the cooling of the skin.

In addition, the second time may mean a time when skin damage due to cooling of the skin starts to occur, and when the skin is cooled for a longer time than the second time, damage to the skin may occur. For example, the second time period may be up to 300 seconds to prevent tissue damage due to ischemia and thrombus in small blood vessels caused by cooling the skin for a long time. However, the second time period may vary depending on circumstances, such as up to 900 seconds, which is a time in which microscopic damage to the skin is possible by cooling the skin for a long time as well as direct damage to the skin.

The cooling duration of the first main surface 31 controlled by the controller 50 does not need to be limited to the above description, and may be variously determined.

Also, the controller 50 may control the thermoelectric module 30 such that the cooling time of the first main surface 31 increases as the temperature at which the first main surface 31 is cooled increases. For example, the controller 50 controls the thermoelectric module 30 so that the cooling time of the first main surface 31 is longer when the temperature at which the first main surface 31 is cooled is 5 °C than when the temperature is -15 °C. ) can be controlled.

In addition, the controller 50 according to an embodiment of the present specification may control the thermoelectric module 30 based on the skin temperature measured from the skin temperature sensor. To this end, the controller 50 may store the input result in the form of a function or a look-up table in the storage unit 54 and use it for calculation. For example, the storage unit 54 may store a current/voltage table related to current and/or voltage for each skin temperature intensity. The controller 50 may determine the magnitude of the current/voltage to be applied by referring to the current/voltage table based on the measured skin temperature.

The controller 50 prevents skin damage due to cooling, but a thermoelectric module to change the cooling conditions of the first main surface 31 based on the skin temperature measured from the skin temperature sensor in order to suppress pigmentation caused by melanocytes ( 30) can be controlled.

The controller 50 may control the thermoelectric module 30 to change the temperature at which the first main surface 31 is cooled based on the skin temperature measured by the skin temperature sensor. For example, the controller 50 lowers the temperature at which the first main surface 31 is cooled when the measured skin temperature is higher than the target temperature, and cools the first main surface 31 when the measured skin temperature is lower than the target temperature. It is possible to control the thermoelectric module 30 to increase the temperature. For another example, when the measured skin temperature reaches the target temperature, the controller 50 may control the thermoelectric module 30 to cool the first main surface 31 to a temperature at which the measured skin temperature is maintained at the target temperature. can

The controller 50 may control the thermoelectric module 30 to vary the cooling time of the first main surface 31 based on the skin temperature measured by the skin temperature sensor. For example, the controller 50 increases the cooling time of the first main surface 31 when the measured skin temperature is higher than the target temperature, and cools the first main surface 31 when the measured skin temperature is lower than the target temperature. It is possible to control the thermoelectric module 30 to reduce the time taken.

In addition, the controller 50 may control the thermoelectric module 30 so that the time for which the measured skin temperature is maintained at the target temperature is longer than the time required for suppression of pigmentation and shorter than the time during which skin damage occurs. For example, the controller 50 may control the thermoelectric module 30 so that the measured skin temperature maintains the target temperature (4°C to 27°C) for 4 seconds to 120 seconds.

However, the first embodiment is not necessarily implemented in the above-described manner, and may be implemented in various ways, such as being implemented in combination with other embodiments according to circumstances.

<Second embodiment>

Hereinafter, a second embodiment in which the controller 50 controls the temperature of the first main surface 31 of the thermoelectric module 30 will be described. Hereinafter, descriptions overlapping with the previous embodiments will be omitted. That is, technical ideas that can be diverted from the previous embodiment will not be repeatedly described in the second embodiment.

11 is a graph illustrating a temperature change over time of a first main surface of a thermoelectric module according to a second embodiment of the present specification.

When the mask 10 cools the user's skin in only one whitening mode, it is difficult to efficiently whiten the skin. This is because when the mask 10 cools the user's skin only in the whitening mode at a too low temperature, damage to the user's skin is easy to occur, and when the user's skin is cooled only in the whitening mode at a too high temperature, pigmentation by melanocytes is suppressed Because it may be less effective.

Specifically, first, the mask 10 cools the user's skin to a first whitening temperature that is lower than the second whitening temperature to rapidly drop the user's skin temperature, thereby increasing the skin whitening effect. However, here, when the mask 10 cools the user's skin to a low temperature first whitening temperature for a long time, skin damage due to low temperature may occur, so that the first whitening time for maintaining the first whitening temperature can be kept relatively short. have.

Next, the mask 10 cools the user's skin to a second whitening temperature higher than the first whitening temperature to reduce skin damage due to low temperature, but can increase the skin whitening effect by cooling the user's skin for a longer period of time. That is, the second whitening time for which the mask 10 maintains the second whitening mode may be longer than the first whitening time for maintaining the first whitening mode.

Therefore, the controller 50 according to an embodiment of the present specification may control the thermoelectric module 30 to sequentially perform the first whitening mode and the second whitening mode under different cooling conditions for efficient skin whitening. Referring to FIG. 11 , the thermoelectric module 30 is controlled by the controller 50 so that the first main surface 31 is cooled to a cooling temperature of T1 for t1. In the first whitening mode, the first main surface 31 is higher than T1. It can be seen that the second whitening mode, which is cooled for t2 longer than t1, is sequentially performed with the cooling temperature T2.

The controller 50 may control the thermoelectric module 30 to sequentially perform the first whitening mode and the second whitening mode under different cooling conditions for efficient skin whitening.

For example, first, the controller 50 controls the thermoelectric module 30 to perform a first whitening mode having a first whitening temperature lower than the second whitening temperature and a first whitening time shorter than the second whitening time. can be controlled

Next, the controller 50 may control the thermoelectric module 30 to perform a second whitening mode having a second whitening temperature higher than the first whitening temperature and a second whitening time longer than the first whitening time. have.

In addition, the controller 50 can control the thermoelectric module 30 in a plurality of whitening modes instead of two whitening modes, and the thermoelectric module 30 in variously combined whitening modes such as each whitening mode is sequentially repeated. can be controlled.

However, the second embodiment is not necessarily implemented in the above-described manner, and may be implemented in various ways, such as being implemented in combination with other embodiments according to circumstances.

<Third embodiment>

Hereinafter, a third embodiment in which the controller 50 controls the temperature of the first main surface 31 of the thermoelectric module 30 will be described. Hereinafter, descriptions overlapping with the previous embodiments will be omitted. That is, technical ideas that can be diverted from the previous embodiment will not be repeatedly described in the third embodiment.

12 is a graph illustrating a temperature change over time of a first main surface of a thermoelectric module according to a third embodiment of the present specification.

In general, when the user's skin is cooled, in addition to the skin whitening effect, the user's skin may have ancillary effects such as a skin swelling reduction effect and a lipolytic effect on the skin. However, the optimum temperature at which the skin whitening effect occurs and the optimum temperature at which ancillary effects such as reducing skin puffiness or decomposing skin lipolysis occur are slightly different.

In general, the cooling temperature for the effect of reducing swelling and decomposition of fat to occur is higher than the cooling temperature for causing the effect of whitening to occur, and the cooling time for causing the effect of reducing swelling and decomposition of fat is the cooling time for causing the effect of whitening. longer than Here, when the user's skin is cooled with repeated increase and decrease in temperature, the fat decomposition effect may increase.

Therefore, the controller 50 according to an embodiment of the present specification may control the thermoelectric module 30 so that the first main surface 31 is cooled even under a condition in which other ancillary effects occur. For example, the controller 50 may control the thermoelectric module 30 so that the first main surface 31 is cooled to a condition in which an effect such as reduction in swelling or decomposition of fat occurs.

12, after the thermoelectric module 30 is controlled by the controller 50 and the whitening mode is performed, the swelling reduction mode and the fat decomposition effect in which the first main surface 31 is cooled under the cooling conditions in which the swelling reduction effect occurs It can be seen that the fat decomposition mode in which the first main surface 31 is cooled is sequentially performed under the cooling condition in which the

The controller 50 may control the thermoelectric module 30 so that the first main surface 31 is cooled to a cooling condition for reducing swelling of the user's skin.

The controller 50 may control the thermoelectric module 30 in a swelling reduction mode in which the first main surface 31 is cooled to a temperature section higher than the whitening temperature section of the whitening mode. For example, the controller 50 may control the thermoelectric module 30 so that the first main surface 31 is cooled to a temperature range of 10 °C to 20 °C higher than the whitening temperature section of the whitening mode.

The thermoelectric module 30 may be controlled to be cooled in the C range.

15 is a graph illustrating a temperature change over time of a first main surface of a thermoelectric module according to a fifth embodiment of the present specification.

Since a plurality of functional materials 21 can be accommodated in the contact layer 20 to obtain a comprehensive skin improvement effect, when a plurality of functional materials 21 are accommodated in the contact layer 20, any one functional material ( 21), when the functional material activation mode is performed in the active temperature section for activating the other functional materials may not be activated.

Therefore, in the controller 50 according to an embodiment of the present specification, when the plurality of functional materials 21 are accommodated in the contact layer 20 , the first main surface 31 of the thermoelectric module 30 is connected to the contact layer 20 . The first functional material activation mode cooled to the first activation temperature range of the accommodated first functional material 21-1 and the second functional material 21-2 in which the first main surface 31 is accommodated in the contact layer 20 ) may control the thermoelectric module 30 in the second functional material activation mode cooled to the second active temperature section.

<Sixth embodiment>

Hereinafter, a sixth embodiment in which the controller 50 controls the temperature of the first main surface 31 of the thermoelectric module 30 will be described. Hereinafter, descriptions overlapping with the previous embodiments will be omitted. That is, technical ideas that can be diverted from the previous embodiment will not be repeatedly described in the sixth embodiment.

16 is a graph illustrating a temperature change over time of a first main surface of a thermoelectric module according to a sixth embodiment of the present specification.

When the power to the thermoelectric module 30 through the controller 50 is cut off after the cooling of the first main surface 31 is completed due to the application of power to the thermoelectric module 30 of the controller 50, the second main surface 32 The temperature of the thermoelectric module 30 rises due to the heat generated in the , and quickly approaches the high temperature of the second main surface 32 . At this time, when heat is suddenly applied to the user's skin cooled to a low temperature through the thermoelectric module 30 whose temperature has risen, the user may feel a large amount of discomfort due to relatively hotness and damage to the skin due to the high temperature may occur.

Therefore, after the cooling of the first main surface 31 is completed (for example, after the whitening mode, the functional material activation mode, etc. are completed), the controller 50 according to an embodiment of the present specification performs the first main surface until the user takes off the mask. The thermoelectric module 30 may be controlled so that the temperature of 31 does not rise rapidly. Referring to FIG. 16 , after the whitening mode in which the first main surface 31 is cooled to a cooling temperature of 5 ° C for 100 seconds is completed, the thermoelectric module 30 is controlled by the controller 50 to gradually the first main surface 31 It can be seen that the desorption mode in which the temperature of is increased is performed. Hereinafter, the detachment mode refers to the controller 50 controlling the temperature of the first main surface 31 after the cooling of the first main surface 31 is completed (after the operation mode ends).

In order to prevent the temperature of the first main surface 31 from rapidly increasing after the cooling of the first main surface 31 is completed, the controller 50 operates the thermoelectric module ( 30) can be controlled. For example, the controller 50 may control the thermoelectric module 30 so that the temperature of the first main surface 31 rises by 0.3°C per second after the cooling of the first main surface 31 is completed.

In addition, the controller 50 may control the thermoelectric module 30 in a detachable mode for maintaining the temperature of the first main surface 31 at a constant temperature after the cooling of the first main surface 31 is completed. For example, the controller 50 may control the thermoelectric module 30 to gradually increase the temperature of the first main surface 31 to reach a temperature of 5°C to 30°C. Alternatively, the controller 50 may control the thermoelectric module 30 to maintain the temperature of the first main surface 31 after the cooling of the first main surface 31 is completed.

In addition, the controller 50 may control the thermoelectric module 30 to maintain the detachment mode for a predetermined time in order to provide sufficient time for the user to take off the mask 10 while the detachment mode is performed. For example, the controller 50 may control the thermoelectric module 30 to perform the detachment mode in a range of 10 seconds to 5 minutes.

In addition, the controller 50 may control the thermoelectric module 30 to end the detachment mode when the user's mask 10 detachment signal is obtained. For example, the controller 50 may control the thermoelectric module 30 to end the detachable mode when receiving a power-off signal from the user or acquiring a user's skin non-sensing signal through the touch sensing unit.

In addition, the controller 50 may control the output unit to output a notification when the detachment mode starts or ends. For example, the controller 50 may control the output unit to output a vibration or voice message notifying the removal of the mask when the removal mode starts. Alternatively, the controller 50 may control the vibration generating unit to output vibration through the vibration generating unit when the detachment mode starts or ends.

However, the sixth embodiment is not necessarily implemented in the above-described manner, and may be implemented in various ways, such as being implemented in combination with other embodiments according to circumstances.
