Abstract

A heating patch for skin care including a substrate unit; an application electrode unit formed on the substrate unit in a predetermined pattern, and which includes a first electrode and a second electrode to which power supplied from the outside is applied; a heating unit including first and second heating electrodes, which respectively extend a predetermined length from the first and second electrodes so as to face each other at a certain length without being electrically connected, and a plurality of conductive heating materials formed to have predetermined areas in an overlapping part in which the first and second heating electrodes face each other and generate heat while allowing the first and second heating electrodes to communicate with each other during application of power; and a pair of cover members arranged on both surfaces of the substrate unit to prevent external exposure of the applied electrode unit and heating unit.

First claim

The invention claimed is:

1. A heating patch for skin care, the heating patch comprising:
a substrate part;
an application electrode part which is formed in a predetermined pattern on the substrate part and includes a first electrode and a second electrode, to which power from an external power source is applied;
a heating part which includes a first heating electrode and a second heating electrode each extending a predetermined length from the first electrode and the second electrode, respectively, and facing each other at portions thereof without being electrically connected to each other, and includes a plurality of conductive heating materials which are formed to have a predetermined area in an overlapping portion where the first heating electrode and the second heating electrode face each other and which are configured to, when power is applied, generate heat while causing electricity to flow between the first heating electrode and the second heating electrode; and
a pair of cover members disposed on both surfaces of the substrate part to prevent external exposure of the application electrode part and the heating part,
wherein each of the first electrode and the second electrode comprises at least two layers including a first pattern disposed on the substrate part and a second pattern attached to the first pattern.

2. The heating patch of claim 1 , wherein the first pattern is a printed pattern formed by filling pores in the substrate part with a conductive paste, and the second pattern is a metal sheet formed in the same shape as the first pattern.

3. The heating patch of claim 1 , wherein the second pattern is attached to one surface of the first pattern via a conductive adhesive layer including a vertical conductive filler.

4. The heating patch of claim 1 , wherein the first electrode is formed along an edge of the substrate part, and the second electrode is formed to be disposed on an inner side of the substrate part.

5. The heating patch of claim 1 , wherein the first electrode includes a first portion and a second portion which are physically separated from each other so that the power from the external power source is able to be simultaneously applied along two paths, and the first portion and the second portion are formed on the substrate part so as to be, with respect to a virtual central line, disposed at both left and right sides of the central line.

6. The heating patch of claim 1 , wherein the heating part is provided as a plurality of heating parts disposed between the first electrode and the second electrode, and the plurality of heating parts are connected in parallel to the application electrode part.

7. The heating patch of claim 6 , wherein the plurality of heating parts are formed so that a total area of a conductive heating material included in each heating part is the same.

8. The heating patch of claim 6 , wherein the plurality of heating parts are formed so that a total length of the first heating electrode and the second heating electrode included in each heating part is the same.

9. The heating patch of claim 1 , wherein the first electrode and the second electrode are formed to have a relatively larger width than the first heating electrode and the second heating electrode.

10. The heating patch of claim 1 , wherein the first heating electrode and the second heating electrode are a linear pattern bent one or more times.

11. The heating patch of claim 1 , wherein the conductive heating material is a conductive constant-temperature heating material.

12. The heating patch of claim 1 , wherein the cover member is made of a material that is moisture-proof and flexible.

13. The heating patch of claim 1 , wherein the cover member is attached to one surface of the substrate part via an adhesive layer or is directly fixed to one surface of the substrate part through heat fusion.

14. The heating patch of claim 1 , wherein the heating patch for skin care is in the form of a sheet mask that corresponds to a face.

15. The heating patch of claim 14 , wherein, during use, the heating part is disposed at a position that corresponds to one or more sites among a forehead, cheeks, and a chin of the face.

16. The heating patch of claim 1 , wherein the substrate part is a porous substrate having flexibility and elasticity.
