In recent years, there have been proposed a variety of skin treatment methods, such as a treatment for dissolving cold fat by the treatment of obesity, a treatment of collagen by heating the underlying tissue of the skin, and a skin treatment for causing a wound healing reaction.

After such treatment for skin treatment, a considerable amount of skin tissue occurs, so the skin should be massaged and restored after the skin treatment.

Conventionally, in a conventional skin-massage apparatus, a massager is usually operated by a vibrating body moving in a straight line. Such a massager generates vibrations by striking the skin, which makes it difficult to apply the apparatus to people with weak skin tissue.

In recent years, in the case of a recent skin treatment, cold fat decomposition procedure is performed, and fatigue of the skin tissue such as skin treatment which causes collagen contraction or wound healing reaction by heating the sub- There is a problem that it is not suitable to be used for restoring the skin after the treatment which gives a severe fatigue to the skin tissue.

The connection body member 30 is disposed on the upper side and includes an air discharge space 31 provided with a discharge port 30a to which the suction unit is connected and an air discharge space 31 below the air discharge space 31, And a motor mounting space 32 that is open at the bottom so that the top surface 11 of the cup member 10 is exposed.

The connecting body member 30 is provided with a partition plate portion 30b for separating the air discharge space 31 from the motor mounting space 32 and sealing the upper portion of the motor mounting space 32.

A connecting body member 30 is mounted on the upper surface portion 11 of the cup member 10 and the rotating motor 40 is seated and mounted.

The upper surface portion 11 of the cup member 10 may be provided with an axial tubular portion 11a through which the main rotating shaft member 50 passes and the axial tubular portion 11a is formed on the upper surface portion 11 of the cup member 10, As shown in Fig.

The refracting portion 16 refracts light emitted toward the outside of the cup member 10 out of the light emitted from the light emitting member 60 toward the inside of the cup member 10, that is, toward the suction space 10a, Allows positive light to be irradiated.

FIG. 2 is a cross-sectional view showing another embodiment of the skin massage cup according to the present invention, in which the light emitting member 60 is disposed in the massage projection 21.

The light emitting member 60 is disposed in the massage projection 21 and irradiates light directly to the skin which is pressed by the massage protrusion 21 to massage the skin as close as possible to the skin, Maximizing the amount of light to be irradiated maximizes the therapeutic effect of light.

In this case, the light emitting member 60 emits light by being supplied with an electric power by the induced electromotive force by the rotation of the massaging rotary member 20.

The skin massage cup according to the present invention includes an induction electromotive force generating unit (not shown) for generating an induced electromotive force by rotation of the massaging rotary member 20 and supplying electric power to the light emitting member 60 disposed in the massage protrusion 21 70).

The induction electromotive force generating unit 70 includes a magnet body 71 including a permanent magnet or an electromagnet which is provided on a side surface 12 of the cup member 10 and generates a magnetic force, a massage protrusion 21, And a coil 72 provided on either side of the coil. It is noted that the induced electromotive force generating section 70 can be modified to various other known embodiments that can induce an induced electromotive force.

The massage rotary member 20 is detachably mounted on the lower end of the main rotary shaft member 50, that is, the lower end of the second rotary shaft portion 52, and can be used interchangeably.

A magnet may be provided on one of the main rotation shaft member 50 and the massaging rotary member 20 and a magnetic body capable of being attached by the magnetic force of the magnet may be provided on the other side of the main rotation shaft member 50, And magnets that are magnetically attached to each other on the base 20 may be provided.

The rotation center of the massaging rotary member 20 is provided with a shaft insertion portion 20a which is protruded to the upper side and into which a lower end portion of the main rotation axis member 50 is partially inserted and a magnetic body or a magnet is positioned on the lower surface.

The main rotating shaft member 50 has a lower end portion inserted into the shaft insertion portion 20a and the massage rotary member 20 is firmly mounted on the lower end portion of the massage rotary member 20 by the magnetic force of the magnet .

The massage massaging cup according to the present invention can use any one of the plurality of massaging rotary members 20 to be attached to the lower end portion of the main rotary shaft member 50 by selecting the massage projection 21 having different shapes .

This is because the skin thickness of the subject to be treated differs from person to person, and there is a difference in the pressing point of the treated area or the elasticity of the skin, so that the practitioner selects and uses the massage rotary member 20 having the massage- It is possible.

It is troublesome to design complex wirings and connection terminals in order to supply power to the light emitting member 60 located in the massage projection 21 when the massage rotary member 20 is selected and used and the connection is unstable Many failures can occur.

The light emitting member 60 positioned in the massage protrusion 21 is stably supplied with the electric power through the induction electromotive force and the electric power source is not consumed separately, Minimize the amount of power consumed when massaging.
