Abstract

Disclosed therein is a tip structure for a skin care apparatus. The tip structure includes a first electrode formed on a substrate mounted on the front end part of a tip case and a second electrode formed on the periphery of the front end part of the tip case so as to provide a wide electrode area. The tip structure for the skin care apparatus, which supplies high frequency energy to the skin through electrodes formed at the front end portion of the tip case, includes: a first electrode formed on the substrate mounted on the front end part of the tip case; and a second electrode formed on a peripheral portion of the front end part of the tip case.

Claims

1. A tip structure for a skin care apparatus to supply high frequency energy to a skin, the tip structure for the skin care apparatus comprising:

a tip case in a hollow tube shape having a wall defining and surrounding an empty inside space, wherein the wall includes an inner face that faces the empty inside space of the tip case, an outer face opposite to the inner face, and a top rim part connecting the inner face and the outer face;

a substrate mounted on the top rim part of the wall, the substrate being surrounded by an outer periphery of the top rim part;

a first electrode formed on an area of the substrate except an edge periphery of the substrate, the first electrode being surrounded by the outer periphery of the top rim part without being extended to the outer face; and

a second electrode coated on the inner face, the top rim part and the outer face of the wall without discontinuity, wherein the second electrode is apart from the first electrode with the edge periphery of the substrate being disposed therebetween,

wherein a to surface of the first electrode, a top surface of the substrate and a top surface of the second electrode are disposed substantially at a same level with each other,

wherein an outermost peripheral surface of the substrate is covered by the inner face of the wall of the tip case, and

wherein the wall of the tip case is a supporting frame of the tip structure that supports the tip structure, and the second electrode disposed on the inner face of the wall is a coated layer which does not work as a supporting frame.

2. The tip structure according to claim 1, wherein the second electrode is formed by plating.

3. A tip structure for a skin care apparatus to supply high frequency energy to a skin, the tip structure for the skin care apparatus comprising:

a tip case in a hollow tube shape that has a wall defining and surrounding an empty inside space, wherein the wall includes an inner face that faces the empty inside space of the tip case, an outer face opposite to the inner face, and a top rim part connecting the inner face and the outer face, the tip case further including a stepped-jaw portion on the inner face of the wall, the stepped-jaw portion including an inner surface that faces the empty inside space of the tip case, an outer surface in contact with the inner face of the wall and a top surface connecting the inner and outer surfaces of the stepped-jaw portion, the top surface of the stepped-jaw portion extending in a direction perpendicular to the inner surface of the stepped-jaw portion to be connected with the inner face of the wall;

a second electrode coated on the top rim part and the outer face of the wall, wherein the second electrode is not coated on the inner face of the wall; and

a first electrode mounted inside the tip case and seated on the top surface of the stepped-jaw portion, the first electrode having a dome-shaped upper face protruding above the top rim part of the wall, the first electrode being electrically insulated from the second electrode by a gap formed between an outer circumference of the first electrode and an inner circumference of the tip case, wherein no material is filled in the gap,

wherein the first electrode has a protrusion formed on an outer circumference thereof seated on the top surface of the stepped-jaw portion, and an outer periphery of the first electrode below the protrusion of the first electrode is in contact with the inner surface of the stepped-jaw portion, and a base of the protrusion is directly seated on and in direct contact with the top surface of the stepped-jaw portion,

wherein a thickness of the stepped-jaw portion in a radial direction is greater than a length of the protrusion of the first electrode in the radial direction, such that the gap is formed between the first electrode and the tip case and that the protrusion of the first electrode, taken from a plan view, is disposed entirely within the thickness of the stepped-jaw portion.

4. The tip structure according to claim 3, wherein the first electrode is made of a metal material having conductivity.
