The flexible polymer 250 may be formed to fill the space between the first flexible electrode 230 and the second flexible electrode 240 . That is, the flexible polymer 250 may be formed to fill the space between the first flexible electrode 230 and the second flexible electrode 240 in which the N-type semiconductor 210 and the P-type semiconductor 220 are located.

In addition, optionally, the flexible polymer 250 may be disposed to cover the outside of the first flexible electrode 230 and the second flexible electrode 240, or a material such as silicone having a high thermal conductivity and a flexible first flexible electrode ( It may be disposed to cover the outside of the 230 and the second flexible electrode 240 .

The flexible thermoelectric element 200 has the same level of performance (ZT = 0.6 to 0.9) as the conventional rigid flat plate thermoelectric element, but has less energy loss because there is no thick ceramic substrate, and the response speed is a general rigid flat plate type thermoelectric element. It has the advantage of being 3 to 4 times faster than the type thermoelectric element. As such, as the flexible thermoelectric element 200 is disposed along the body 100 to form a curved surface, a single flexible thermoelectric element 200 is more effective for the body. A feeling of cooling or a feeling of heat may be provided. Here, the meaning of 'only a single flexible thermoelectric element 200' refers to a structure in which a plurality of general rigid thermoelectric elements have to be arranged in order to provide a similar feeling of cooling or heat to a curved part of the body as a single flexible thermoelectric element (200). ) means that it can be replaced. That is, it is not to be construed that the flexible thermoelectric element 200 is provided in the face care mask of the present invention as limited.

Although the flexible thermoelectric element 200 has been described and illustrated as including the flexible polymer 250 in the above description, it is not necessarily limited thereto. The flexible polymer 250 may not be provided, and air may be filled between the first flexible electrode 230 and the second flexible electrode 240 . In this case, a thin film is disposed on the outside of the first flexible electrode 230 and the outside of the second flexible electrode 240 , respectively, and may have ductility while maintaining structural stability by itself. Alternatively, the cold and hot pad 300 and the buffer unit 400 may be coupled to the outside of the first flexible electrode 230 and the outside of the second flexible electrode 240, respectively, to maintain structural stability.

The flexible thermoelectric element 200 may include a plurality of thermoelectric elements having the same function and structure as the individual flexible thermoelectric element 200 but having a smaller size. The plurality of thermoelectric elements may be disposed to be spaced apart from each other at a distance sufficient to prevent interference from occurring.

The buffer unit 400 may be disposed to cover the other surface of the flexible thermoelectric element 200 on the other surface opposite to the one surface of the flexible thermoelectric element 200 facing the cold and hot pad 300 .

The buffer unit 400 may include a buffer body forming an outer shape and a filler filled in the buffer body. The buffer body is in surface contact with the other surface of the flexible thermoelectric element, and may be formed of a flexible material that can change its shape in response to a change in the shape of the flexible thermoelectric element. For example, the buffer body may be formed of silicone, urethane, or the like.

The filler is filled in the buffer body and formed to exchange heat with the other surface of the flexible thermoelectric element. The filler may be formed in a liquid or gel type, and may include a fluid having a high heat capacity (eg, water).

Accordingly, the buffer unit 400 may absorb heat generated in the flexible thermoelectric device 200 or transfer heat to the flexible thermoelectric device 200 . The buffer unit 400 may be disposed outside the flexible thermoelectric element 200 according to the stacking order described above, and thus may buffer the temperature change of the flexible thermoelectric element 200 . The buffer unit 400 may contain a fluid so as to have a heat capacity sufficient to sufficiently absorb latent heat in consideration of the time that the flexible thermoelectric element is used.

The case 500 is disposed to cover the buffer unit 400 and may be exposed to the outside of the body. The case 500 exposed to the outside may be in contact with air to exchange heat. Accordingly, it is possible to reduce the temperature change of the buffer unit 400 .

Specifically, the case 500 may include a heat sink 510 , a frame 520 , and a fixing screw 530 . The heat sink 510 may radiate heat to the outside, and more specifically, when the buffer unit 400 receives heat from the flexible thermoelectric element 200 , the heat is primarily spread to the fluid in the buffer unit 400 and , this heat may be transferred back to the heat sink 510 . In addition, when heat is absorbed from the other surface of the flexible thermoelectric element 200 , the buffer unit 400 may provide heat to the flexible thermoelectric element 200 , and accordingly, the temperature of the buffer unit 400 decreases. In this case, the heat sink 510 may exchange heat with the buffer unit 400 by using an external temperature difference. Accordingly, the heat sink 510 may increase or decrease the temperature of the buffer unit 400 .

To this end, the heat sink 510 may be formed in a form in which a plurality of protrusions protrude outward, such as a cooling plate for electronic products. This may increase the contact area with the outside air to cause smoother heat transfer. These protrusions can be formed with patterns to express brand images or pictures.

The frame 520 may fix the heat sink 510 . Specifically, referring to the exploded perspective view of FIG. 3 , the heat sink 510 may be stacked in contact with the buffer unit 400 , and the other side of the heat sink 510 opposite to the buffer unit 400 has a heat The outer body 120 having an outer opening 122 having a size smaller than the circumference of the heat sink 510 may be positioned so that the sink 510 passes therethrough. A portion of the heat sink 510 may protrude outward through the outer body 120 , and the frame 520 may be disposed on one side of the heat sink 510 .

In this example, the frame 520 may be formed, for example, in a loop shape corresponding to the edge shape of the heat sink 510 . The frame 520 and the heat sink 510 are disposed to overlap, and the fixing screw 530 passes through the frame 520 and is fixed to the heat sink 510 , and the frame 520 and the heat sink 510 . A portion of the outer body 120 is disposed on the outer body 120 so that the outer body 120 may also be fixed by the fixing screw 530 .

The case 500 may be made of a material that facilitates heat transfer and may have a hardness (hardness) enough to protect the buffer unit 400 and the flexible thermoelectric element 200 .

Although the frame 520 has been illustrated and described as being formed in a loop shape above, it is not necessarily limited thereto. The frame 520 may have various shapes, for example, may be formed in a plate shape, or may have a mesh shape.

Referring back to FIG. 4 , the case 500 may form a pressure in the direction of a specific part of the face by the body 100 including the fixing part 130 . At least a part of the body 100 (eg, the entire body or a fixing part) has elasticity, and when the body 100 is worn as a facial part, the body 100 presses the circumference of the head to be fixed to the head. can do. This pressure may cause the case 500 to face the face, and accordingly, the buffer unit 400 overlapping in the face direction in the case 500 may be pressurized. The buffer unit 400 can be pressed in the direction of the face region by the case 500 to press the flexible thermoelectric element 200, and the flexible thermoelectric element 200 is a cold and hot pad 300 that is in contact with the skin of a specific part of the face. can be pressurized.

At this time, the hot and cold pad 300 , the flexible thermoelectric element 200 , and the buffer unit 400 may be deformed into a shape corresponding to the curvature of a specific part of the face. If the case 500 is sufficiently hard or the body 100 presses the buffer unit 400 through the case 500 or the outer body 120, the buffer unit 400 is pressed by the case 500 and It is deformed into a shape corresponding to the curvature of a specific part, and in the case of the fluid filled in the buffer unit 400, the degree of freedom of deformation is large, so that the pressure can be distributed to the flexible thermoelectric element 200 so as to be in close contact with the specific part of the face. Accordingly, the flexible thermoelectric element 200 and the cold/hot pad 300 may also be deformed to correspond to the curvature of a specific part of the face and be in close contact.

This case 500 may be provided with a hard material in order to properly distribute the pressure to the buffer unit 400 described above, but may have a certain flexibility so that the shape can be appropriately changed according to the user. . Alternatively, a plurality of cases 500 may be disposed on one flexible thermoelectric element 200 to be easily deformed according to the user's facial appearance.

In addition, the plurality of flexible thermoelectric elements 200 may be spaced apart from each other and disposed on the body 100 , but the hot and cold pad 300 , the buffer unit 400 , and the case 500 are spread over a plurality of places on the body. Each of the flexible thermoelectric elements 200 may be disposed at positions corresponding to each other, or may be disposed to surround all the corresponding regions.

For example, as shown in FIGS. 1 to 4 , the cold and hot pad 300 , the buffer unit 400 , and the case 500 may be respectively disposed on individual flexible thermoelectric elements 200 . If there are eight flexible thermoelectric elements 200 , eight each of the hot and cold pad 300 , the buffer unit 400 , and the case 500 may be provided.

Alternatively, the hot and cold pad 300 , the buffer unit 400 , and the case 500 may be disposed to overlap the plurality of flexible thermoelectric elements 200 . For example, when two of the four flexible thermoelectric elements 200 are disposed in the first part 100-1 and two are respectively disposed in the second part 100-2, one cold/hot pad 300, One buffer unit 400 and one case 500 may overlap both the two flexible thermoelectric elements 200 disposed in the first part 100-1, and the other cold/hot pad 300 , the other buffer unit 400 and the other case 500 may all overlap the two flexible thermoelectric elements 200 disposed in the second part 100 - 2 .

Alternatively, one case 500 may be formed to cover one hot and cold pad 300 , four flexible thermoelectric elements 200 , and two buffer units 400 . For example, each of the hot and cold pad 300 , the buffer unit 400 , and the case 500 may be provided with less or the same number than the flexible thermoelectric element 200 .

Referring to FIG. 8, flexible thermoelectric elements 1200-1, 1200-2, 1200-3, 1200-4, 1200-5, 1200-1', 1200-2', 1200-3', 1200- 4', 1200-5') is formed so as to exchange heat with the skin by the hot and cold pad 1400 or the inner body 110 . In the case of exothermic driving, the hot and cold pad 1400 is a flexible thermoelectric element (1200-1, 1200-2, 1200-3, 1200-4, 1200-5, 1200-1', 1200-2', 1200-3', 1200-4', 1200-5') and the skin to prevent burns due to direct heat transfer.

These flexible thermoelectric elements (1200-1, 1200-2, 1200-3, 1200-4, 1200-5, 1200-1', 1200-2', 1200-3', 1200-4', 1200-5' ) is described with reference to the flexible thermoelectric elements 1200-1, 1200-2, 1200-3, 1200-4, and 1200-5 disposed in the first area, the 1-1 flexible thermoelectric element ( When the 1200-1) is heat-driven, the 1-2-th flexible thermoelectric element 1200-2 may also be driven with heat, and when the 1-1-th flexible thermoelectric element is endothermic driven, the 1-2-th flexible thermoelectric element The device 1200 - 2 may be endothermic driven. This actuation is similar to other flexible thermoelectric elements (1200-1, 1200-2, 1200-3, 1200-4, 1200-5, 1200-1', 1200-2', 1200-3', 1200-4', 1200-5') as well. That is, adjacent flexible thermoelectric elements (1200-1, 1200-2, 1200-3, 1200-4, 1200-5, 1200-1', 1200-2', 1200-3', 1200-4', 1200- 5') may perform endothermic drive or exothermic drive in the same way as each other, and may be endothermic drive or exothermic drive opposite to each other. .

Each of these control units is a flexible thermoelectric element (1200-1, 1200-2, 1200-3, 1200-4, 1200-5, 1200-1', 1200-2', 1200-3', 1200-4') , 1200-5' can selectively provide a first direction current and a second direction current periodically alternately, and therefore flexible thermoelectric elements (1200-1, 1200-2, 1200-3, 1200-4, 1200-) 5, 1200-1', 1200-2', 1200-3', 1200-4', and 1200-5'), the endothermic and exothermic driving may be periodically repeated.

These flexible thermoelectric elements (1200-1, 1200-2, 1200-3, 1200-4, 1200-5, 1200-1', 1200-2', 1200-3', 1200-4', 1200-5' ) can be driven with a certain pattern.

In the present invention, a plurality of flexible thermoelectric elements (1200-1, 1200-2, 1200-3, 1200-4, 1200-5, 1200-1', 1200-2', 1200-3', 1200-4', 1200-5') can be operated.

An example of this is shown in FIG. 8 . Referring to FIG. 8 ( a ), when the face care mask is operated, the first and second flexible thermoelectric elements 1200 - 2 may be driven by endothermic heat, and the remaining flexible thermoelectric elements 1200 - 1 , 1200 - 3 , 1200-4, 1200-5) may be driven by heat.

Referring to FIG. 8(b) , after a predetermined time elapses, the 1-3 flexible thermoelectric element 1200-3 adjacent to the 1-2 flexible thermoelectric element 1200-2 may be switched to be endothermic driven. There, the 1-2 flexible thermoelectric element 1200-2 may be converted to be driven by heat. The remaining 1-1 flexible thermoelectric element 1200-1, 1-4 flexible thermoelectric element 1200-4, and 1-5 flexible thermoelectric element 1200-5 may maintain heat-generating driving.

After this driving conversion is performed, the 1-4 th flexible thermoelectric element 1200-4 may be switched to be endothermic driven, and thereafter, the 1-5 th flexible thermoelectric element 1200-5 will be switched to endothermic driven. can

Specifically, the lymphatic vessels of the human body are roughly laid out in a direction that passes sequentially from the nose to the chin and neck, and similarly, the lymph fluid can go down from the nose to the chin and neck sequentially. As shown in FIGS. 8(a) and 9(b), flexible thermoelectric elements 1200-1, 1200-2, 1200-3, 1200-4, 1200-5, 1200-1', 1200-2' , 1200-3', 1200-4', 1200-5') can selectively provide a feeling of coolness and heat, the skin layer (S) portion to which the cooling sensation is provided contracts, and the skin layer (S) portion to provide a feeling of heat is relaxed Therefore, the skin layer (S) can receive an effect similar to that the part where the feeling of cooling is pressed, and if this feeling of cooling is continuously moved, the effect of a massage by pressing the skin with a hand and pushing it in one direction can be expected.

Accordingly, a plurality of flexible thermoelectric elements (1200-1, 1200-2, 1200-3, 1200-4, 1200-5, 1200-1', 1200-2', 1200-3', 1200-4', 1200-5') is arranged to move the feeling of cold in the same direction as the formation of the lymphatic vessels, and by endothermic driving in the order of arrangement, the movement of the feeling of cold can be achieved in one direction.

The cooling sensation is from the 1-1 flexible thermoelectric element 1200-1 disposed adjacent to the nose to the 1-1 flexible thermoelectric element 1200-1 and the 1-2 flexible thermoelectric element 1200-2 adjacent thereto, and the After the 1-3 flexible thermoelectric element (1200-3), then the 1-4 flexible thermoelectric element (1200-4), and then the 1-5 flexible thermoelectric element (1200-5) disposed adjacent to the ear in that order can be moved In addition, this driving may be repeated, and after the 1-5 th flexible thermoelectric element 1200 - 5 is driven by endothermic heat, the 1-1 th flexible thermoelectric element 1200 - 1 may generate heat again.

That is, 1-1 flexible thermoelectric element 1200-1, 1-2 flexible thermoelectric element 1200-2, 1-3 flexible thermoelectric element 1200-3, 1-4 flexible thermoelectric element 1200 -4) and the 1-5 flexible thermoelectric element 1200-5 may be sequentially endothermic and driven, and the heat may be transferred by sequentially exothermic driving again after endothermic driving.

In addition, the conversion between the endothermic drive and the exothermic drive may be performed at a predetermined time interval. The endothermic driven flexible thermoelectric element may be converted to exothermic driving, and one or more adjacent flexible thermoelectric elements may be converted from exothermic to endothermic driving. At this time, the conversion to the exothermic drive may be started at the same time, or the conversion to the endothermic drive may be completed after the conversion to the endothermic drive is completed. For example, the 1-1 flexible thermoelectric element 1200-1 drives endothermicly, the 1-2 flexible thermoelectric element 1200-2, the 1-3 flexible thermoelectric element 1200-3, and the 1-th flexible thermoelectric element 1200-3 In a state where the 4 flexible thermoelectric element 1200-4 and the 1-5 flexible thermoelectric element 1200-5 are driven by heat, the 1-2 flexible thermoelectric element 1200-2 may first endothermic drive, and then The 1-1 flexible thermoelectric element 1200-1 may be driven by heat.

Specifically, for example, when a current in the first direction is applied to the 1-1 flexible thermoelectric element 1200-1 to drive endothermicly, the 1-2 flexible thermoelectric element 1200-2 has a second direction of the current. An electric current may be applied to generate heat driving. Thereafter, the 1-2 th flexible thermoelectric element 1200-2 may drive endothermicly, and accordingly, the 1-1 th flexible thermoelectric element 1200-1 and the 1-2 th flexible thermoelectric element 1200-2 absorb heat at the same time. It can exist in a running state. Thereafter, the 1-1 flexible thermoelectric element 1200-1 may be driven to return to room temperature or heat generated due to power cut off, and accordingly, only the 1-2 flexible thermoelectric element 1200-2 may exist in a state of endothermic driving. have. In addition, similarly, when the 1-2 flexible thermoelectric element 1200-2 is driven by endothermic heat, the 1-3 flexible thermoelectric element 1200-3 may be driven with heat. Thereafter, the 1-3 flexible thermoelectric element 1200-3 may drive endothermicly, and accordingly, the 1-2 flexible thermoelectric element 1200-2 and the 1-3 flexible thermoelectric element 1200-3 absorb heat at the same time. It can exist in a running state. After that, the 1-2 th flexible thermoelectric element 1200-2 may be driven to return to room temperature or heat generated due to power cut off, and accordingly, only the 1-3 th flexible thermoelectric element 1200-3 may exist in a state of endothermic driving. have.
