Plasma skin care device

A plasma skin care device comprising:

• a handpiece which has a plasma generator and discharges plasma in a state in which a front end portion of the plasma generator is adjacent to skin;
• an ozone decomposition module configured to receive and decompose ozone, which is generated when the plasma is discharged, from the handpiece;
• and
• a suction fan configured to draw the ozone generated in the handpiece to the ozone decomposition module by suction pressure,
• wherein the plasma generator is formed to have a cylindrical body extending forward in a main body casing of the handpiece having an open front surface so that plasma is discharged from a front end portion of the body of the plasma generator,
• wherein the plasma skin care device further comprises:
• a ring-shaped skin contact member which is selectively mountable on an accommodating cup, which is provided in the front end portion of the main body casing of the handpiece to have an open front surface, so as to be pressed against the skin stably regardless of the presence of foreign substance or irregular protrusion of the skin in order to intensively care for a certain area of the skin,
• wherein the skin contact member includes:
• a ring-shaped main body portion having a fitting groove in a rear surface thereof so as to be fitted along a circumferential portion of a front end portion of the accommodating cup;
• a double outer wall portion having double outer walls which extend to protrude forward along an inner circumferential portion and an outer circumferential portion of a front end portion of the main body portion so as to be spaced apart from each other and to be brought into contact with the skin;
• a double inner wall portion having double inner walls which are formed in an inner space formed by the double outer wall portion so as to be spaced apart from each other and to be brought into contact with the skin;
• and
• an elastic connecting film configured to elastically support the double inner wall portion in being slid forward or backward with respect to the double outer wall portion,
• the elastic connecting film includes a thin film portion, which is formed as a thin film having a thickness relatively smaller than that of other portions at a portion adjacent to the double outer wall portion, and a connecting portion which is formed to have a thickness gradually increasing from the thin film portion to the double inner wall portion, and
• when a force acts on the double inner wall portion in a direction in which the double inner wall portion is retracted, the double inner wall portion rotates about the thin film portion and is bent, and the connecting portion is bent in an arc shape, which is convex in a rearward direction, and thus the double inner wall portion is allowed to be retracted, and then, when the force acting on the double inner wall portion disappears, the double inner wall portion is returned to an initial position thereof by elastic force of the connecting portion.
