BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a heating patch for skin beauty and a warming device for skin beauty comprising the same.

In general, a mask pack is a product for supplying nutrition to the skin side and skin elasticity by containing an active substance containing various ingredients useful for the skin such as a moisturizing agent, a whitening agent, and cosmetics.

Such a mask pack is made of a nonwoven fabric or the like so that a large amount of active substance or cosmetics can be absorbed to the skin side. However, the effective ingredient contained in the mask pack has a problem that satisfactory skin absorption amount and efficacy can not be obtained by the simple absorption method.

To improve this, a conventional mask pack has been utilized in many ways to improve the composition of an effective ingredient or a cosmetic composition. However, this method raises manufacturing cost in terms of cost and deteriorates the efficiency relative to an increased price.

Alternatively, a method of providing heat through a planar heating element has been proposed. However, in the conventional method, since the surface heating element is simply attached to the outer surface body, there is a problem that when applied to the bent portion of the body, the surface heating element can not be brought into close contact with the bent portion. There is a limit that can not be.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art to which the present invention pertains. The present invention may be embodied in many different forms and is not limited to the embodiments described herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and the same reference numerals are assigned to the same or similar components throughout the specification.

The heating patch 100 for skin beauty according to an embodiment of the present invention may have a shape including a portion having a non-uniform width along one direction as shown in FIG.

For example, the heating patch 100 for skin beauty may have a concave shape with one side inward and a shape similar to an eyebrow. In addition, the skin patches 100 may have various shapes such as a rectangle, a square, and a polygonal shape except for a shape having a constant width along the length direction, such as a circle, arc, and a rectangle.

However, the shape of the heating feathery patch 100 according to an embodiment of the present invention is not limited thereto, and may have a rectangular shape having a constant width along the length direction.

At this time, the heating patch 100 for a skin and beauty according to an embodiment of the present invention can be realized such that the heat generating part generates heat at a constant temperature regardless of its position.

1 and 2, the heating patch 100 for a skin and beauty according to an embodiment of the present invention includes a base substrate 110, electrode portions 121 and 122, a heating portion 130, (140).

The base substrate 110 may be in the form of a plate having a predetermined area and may support at least the electrode parts 121 and 122 and the heat generating part 130 formed on one surface. For example, the base substrate 110 may have substantially the same shape as the cover member 140, and may be prevented from being exposed to the outside by being disposed inside the cover member 140.

At this time, the base substrate 110 may be made of a material having flexibility and flexibility, and cracks may be prevented from occurring due to deformation of the electrode patterns constituting the electrode portions 121 and 122, have.

For this purpose, the base substrate 110 may be formed of a nanofiber web having micropores.

For example, the base substrate 110 may be a nanofiber web having a three-dimensional network structure such that the nanofibers 112 including the synthetic polymer have micropores 114 as shown in FIG.

At this time, if the electrode parts 121 and 122 are implemented by a printing method using a conductive paste, the conductive paste may be filled in the base pores 114 of the base substrate 110.

Accordingly, the base substrate 110 may serve as a circuit board on which the electrode portions 121 and 122 are pattern-formed. As described above, the base substrate 110 is made of a nanofiber web in which nanofibers are accumulated to serve as a circuit board capable of forming a pattern of the electrode portions 121 and 122, thereby making the polyimide film And it is possible to restore the original flat state even if it is folded or wrinkled.

Even if the base substrate 110 is warped or wrinkled, the electrode portions 121 and 122 may be filled with particles of the paste on the side of the micropores 114 formed on the base substrate 110 together with the surface of the base substrate 110 The possibility of cracking can be reduced.

In addition, even if a crack is generated in a part of the pattern constituting the electrode portions 121 and 122 due to warping or wrinkling, at least a part of the pattern can be maintained connected through the paste filled in the fine pores 114, It is possible to significantly reduce the possibility of occurrence.

At this time, the pore size of the micropores 114 may be appropriately sized considering the particle size of the paste. This is because penetration or impregnation of the paste particles may not be smooth when the pore size of the micropores is too small.

As a specific example, the base substrate 110 may be a single-layer or multi-layer nanofiber web accumulated so as to have fine pores 114 by electrospinning a spinning solution containing a synthetic polymer and a solvent. Here, the solvent may be water or an alcohol, or may be an organic solvent other than water or alcohol.

In this case, the synthetic polymer may be a fiber-forming polymer capable of realizing a nanofiber web through electrospinning while having elasticity and flexibility. As a concrete example, the synthetic polymer may be a polyvinylidene fluoride (PVDF) alone or a mixture of PVDF and polyurethane (PU) in a certain amount, but the present invention is not limited thereto, And all materials known in the art can be used as long as it is a fiber-forming polymer having stretchability and flexibility.

As described above, the heating patch 100 for skin and beauty according to an embodiment of the present invention is configured such that the base substrate 110 on which the electrode portions 121 and 122 are formed is realized in the form of a nanofiber web through a synthetic polymer having elasticity and flexibility Elasticity and flexibility can be ensured.

Accordingly, even if the heating patch 100 for skin and beauty according to the present invention adheres to a curved portion of the skin such as a face, natural deformation can be performed in accordance with a curved portion, thereby increasing adhesion to the skin. Accordingly, the heat generated in the heat generating unit 130 can be smoothly transmitted to the skin.

As shown in FIG. 2, the electrode units 121 and 122 may be formed in a predetermined pattern on at least one surface of the base substrate 110, and may provide a path through which a current flows when the power source is applied.

The electrode parts 121 and 122 may be formed in a predetermined pattern on one side of the base substrate 110 through various known methods such as plating, etching, and printing using a conductive material.

For example, the electrode portions 121 and 122 may be formed on the base substrate 110 through a printing method using a conductive paste, and the conductive paste may be formed on one surface of the base substrate 110, The formed micropores 114 can be completely or partially filled. Here, the conductive paste may be an Ag paste, but not limited thereto, and any known conductive paste used for forming an electrode may be applied.

The electrode units 121 and 122 may include a first electrode unit 121 and a second electrode unit 122 that are not electrically connected to each other. When the power is applied, the first electrode unit 121 and the second electrode unit 122 The electrode unit 121 and the second electrode unit 122 may be connected to each other.

3 to 5, the first electrode unit 121 may include a first lead electrode 121a having a predetermined length and a first lead electrode 121a spaced apart from the first lead electrode 121a in one direction And may include a plurality of first branched electrodes 121b extending.

The second electrode unit 122 includes a second lead electrode 122a having a predetermined length and a plurality of second branched electrodes 122b extending in a direction spaced apart from the second lead electrode 122a .

The first and second lead electrodes 121a and 122a may be formed along the rim of the base substrate 110 and the first and second branched electrodes 121b and 122b may be formed on the base substrate 110 Respectively, from the first and second lead electrodes 121a and 122a, respectively.

The first branched electrode 121b and the second branched electrode 122b may be alternately arranged along the longitudinal direction of the base substrate 110. The first branched electrode 121b and the second branched electrode 122b may be alternately arranged along the longitudinal direction of the base substrate 110, The branched electrodes 122a may be arranged such that at least a part of the total length overlaps each other.

Accordingly, the two first branch electrodes 121b and the second branch electrodes 122a, which are arranged so that at least part of the lengths thereof are overlapped with each other, can be paired with each other, and a plurality of first branched electrodes 121b, And the second branched electrodes 122a may be spaced apart from each other along the longitudinal direction of the base substrate 110. [

In this case, the heating unit 130 is formed in a predetermined area in the overlapping portion between the two first branched electrodes 121b and the second branched electrodes 122a, so that the plurality of heating units 130 ).

The heating unit 130 may be formed to have an area including a part or an entire area of the overlapping area between the two first branched electrodes 121b and the second branched electrodes 122a .

In addition, the heat generating unit 130 may include two first branched electrodes 121b and a second branched electrode 121b, which are paired with the overlapping portions between the two first branched electrodes 121b and the second branched electrodes 122a, May be formed to have an area including both widths of the two electrodes 122a.

5, the width W2 of the heat generating part 130 is set to be equal to the distance d1 between the two first branched electrodes 121b and the second branched electrodes 122a which are paired with each other, And may have a size equal to or larger than the sum of the widths W1 of the first branched electrodes 121b and the second branched electrodes 122a.

At this time, the heat generating unit 130 may include two first branched electrodes 121b and a second branched electrode 122a which are paired with each other, and may be made of a conductive heating material so that heat may be generated. .

Accordingly, when power is supplied, the first and second electrode units 121 and 122 are connected to the heating unit 130 connecting the first branched electrode 121b and the second branched electrode 122a And the heat generating unit 130 may generate heat by using the supplied power source.

Accordingly, the heat-generating patch 100 for a skin and beauty according to an embodiment of the present invention can realize a thermal function through heat generated in the heat-generating unit 130 when power is supplied. As a result, penetration of the active ingredient into the skin side of the user is promoted, and the effect of increasing skin beauty through the active ingredient can be enhanced. In addition, it can transmit heat to the skin of the user to help activate skin collagen, and can open pores to induce the discharge of unnecessary waste products.

The heating unit 130 may be made of a conductive constant temperature heating material so that the heating unit 130 can uniformly generate heat at a target temperature during power supply. Here, the conductive constant-temperature heat generating material is a known PTC material for increasing the resistance and suppressing the heat generation temperature when the temperature rises, and more specifically, it may be a conductive carbon paste.

Accordingly, when the heating temperature reaches the target temperature during the power supply, the heating unit 130 cuts off the flow of the current through the increase of the resistance to prevent the first electrode unit 121 and the second electrode unit 122 The electrical connection can be disconnected.

The heating unit 130 may electrically connect the first electrode unit 121 and the second electrode unit 122 to each other by allowing a current to flow therethrough if the heating temperature is lower than the target temperature .

Accordingly, the heat generating unit 130 can be heated again to the target temperature through the heat generation. Accordingly, the heating unit 130 for the skin and beauty according to the embodiment of the present invention can be always realized at a uniform temperature through the above-described process.

At this time, the heating patch 100 for skin beauty according to an embodiment of the present invention minimizes a temperature deviation generated in the plurality of heat generating portions 130 regardless of the overall shape, The plurality of heat generating portions 130 arranged along one another can generate heat at the same temperature regardless of the forming positions. In particular, even though at least a part of the heat-generating patch 100 for skin beauty has a shape having a different width along the longitudinal direction, the plurality of heat-generating portions 130 can generate heat at the same temperature irrespective of their forming positions. Accordingly, the heat generating patch 100 for a skin and cosmetic according to an embodiment of the present invention can achieve a uniform heat generating temperature over the entire area.

To this end, the plurality of heat generating units 130 arranged along the longitudinal direction of the base substrate 110 may be set to have the same resistance.

That is, the plurality of heat generating portions 130 may be formed by a distance d1 between the first branched electrodes 121b and the second branched electrodes 122a which are paired with each other, and branched electrodes d1, d2, 122b can be set to have uniform resistance to each other by adjusting the side area A thereof.

The lateral area A of the branched electrodes 121b and 122b covered by the conductive heating material is formed by the protruding thickness of the branched electrodes 121b and 122b projecting from one surface of the base substrate 110 And when the conductive heating material and the conductive paste are filled on the side of the micropores 114 of the base substrate 110, the filling depth of the conductive heating material and the conductive paste filled in the micropores 114 Or may be a side area including.

For example, the plurality of heat generating units 130 may include a plurality of heat generating units 130 among the overlapped lengths of the first branched electrodes 121b and the second branched electrodes 122a, The distance d1 between the first branched electrodes 121b and the second branched electrodes 122a, which are paired with each other based on the overlapping length, is adjusted.

That is, when the overlap lengths of the two first branched electrodes 121b and the second branched electrodes 122a of the plurality of heat generating units 130 are relatively long, two first branched The distance d1 between the electrode 121b and the second branch electrode 122a may be relatively wide and the distance between the two first branched electrodes 121b and the second branched electrode 122b When the overlap length of the branched electrodes 122a is relatively short, the interval d1 between the two first branched electrodes 121b and the second branched electrodes 122a, which are paired with each other, may also be relatively small.

In other words, the distance d1 between the two first branch electrodes 121b and the second branch electrodes 122a, which are paired with each other, is set such that the first branched electrode 121b and the second branched electrode 122a overlap each other And may be formed to have different intervals depending on the length.

Accordingly, although the heat generating patches 100 for skin and beauty according to the embodiment of the present invention have a plurality of heat generating portions 130 arranged along the longitudinal direction and having different lengths, the plurality of heat generating portions 130 The heat generation temperature of each of the heat generating portions 130 can be uniformly maintained with respect to the entire area irrespective of the overall shape.

In addition, the plurality of heat generating units 130 may be set to have different lengths, so that the entire shape of the heating patch 100 for skin and beauty is formed to have a shape including a portion having a non- The overlap length in which the first branched electrodes 121b and the second branched electrodes 122a are overlapped with each other can be increased to a portion close to the lead electrodes 121a and 122a. Accordingly, a portion of the heat generated by the heat generating portion 130 can be enlarged to an area approximately equal to the entire area of the heating patch 100 for skin beauty.

2 to 5, the lead electrodes 121a and 122a are formed to have a relatively larger width than the plurality of branched electrodes 121b and 122b extending from the lead electrodes 121a and 122a .

This is because the resistance of the lead electrodes 121a and 122a can be smaller than the resistances of the branched electrodes 121b and 122b so that the power supplied from the outside is supplied to the lead electrodes 121a and 122a through the lead electrodes 121a and 122a. So that the heat can be smoothly moved toward the electrodes 121b and 122b and the amount of heat generated by the resistance can be reduced to lower the heat generation temperature generated by the lead electrodes 121a and 122a.

4, the distance d1 between the two first branched electrodes 121b and the second branched electrodes 122a in which the conductive heating material is disposed is smaller than the distance d1 between the first branched electrode 121b and the second branched electrode 122a, May be spaced relatively narrower than the distance d2 between the branch electrode 121b and the second branch electrode 122a. Accordingly, the heating unit 130 can be rapidly heated to the target temperature while minimizing the amount of the conductive heating material.
