Abstract

A facial treatment device comprises an easy-to-grip lower casing which incorporates an electric motor, an oscillating rotary massaging member adapted to one end of an upper casing together with a sheet cover to cover the front section of said massaging member which is detachable therefrom, a piston fitted to the other end of said upper casing for reciprocation inside a cylinder so as to generate suction by means of a crank shaft, means for regulation of suction and a cover for collecting impurities during suction operation.

Claims

1. A facial treatment comprising:

a. an easy to grip lower casing (1) incorporating a motor (3) therein;

b. an upper casing (2) angularly fitted aslant to said lower casing on both sides thereof;

c. a crank shaft (10) including a crank pin (33) disposed at substantially the center inside said upper casing (2) which crank shaft is interposed rotatably for connection with said motor (3) and a reduction gear mechanism (6) and may be dismounted;

d. a massaging member (19) with an outer side for engaging facial skin and an inner side connected to one end of said upper casing (2) via said crank shaft;

e. a pair of bevel gears (12) engaging with each other and a universal joint, one of said bevel gears being connected to said crank shaft, the other being connected to said universal joint, said universal joint being connected to said massaging member inner side which is mounted thereon, and capable of dismounting therefrom and of rotating while performing an oscillating motion;

f. a stepped cylinder in said upper casing (2) toward the other end thereof having therein a piston (32) in interlock with said crank pin (33) capable of reciprocation inside said cylinder so as to cause suction and a cap (38) having suction holes (37) fitted to the distal end (38b) of said cylinder at the other end of said upper casing.

2. A relief valve for use in the facial treatment device as set forth in claim 1, said relief valve comprising a pore passing through the cylinder and the upper casing to interconnect the inside of the cylinder to the outside, a cylindrical element fitted into said pore, an adjusting screw equipped with an air inlet and locked to said cylindrical element, a ball adapted to said adjusting screw to open or close said air inlet by means of suction inside the cylinder, and a spring interposed between said ball and a protrusion of said cylindrical element.

3. A device as claimed in claim 1 including an elastic friction plate fitted to the outer side of the massaging member where it is in touch with the face for use in the facial treatment device wherein the surface of said elastic friction plate has a configuration to match intended type of massage.

4. A device as claimed in claim 1 including holding means at said upper casing one end, a sheet cover for use in the facial treatment device said sheet cover being a sheet made of a thin elastic membrane held by said holding means as a cover while being in touch with the outer side of the massaging member, and also being capable of dismounting.

5. A device as claimed in claim 1 including said cover detachably fitted to said cap (38) and having a concave portion therein to collect impurities during suction.

6. A device claimed in claim 1 including a suction regulation valve comprising a small aperture passing through the cylinder and the upper caSing so as to interconnect the inside of the cylinder to the outside, a ring interposed rotatably between the cylinder, the upper casing and the cap, and a slit formed at a position where the ring faces with the small aperture in such a fashion that rotation of the ring varies the opening of the small aperture.

7. A device as set forth in claim 1 including a relief valve comprising an aperture passing through the cylinder and the upper casing to interconnect the inside of the cylinder to the outside, a cylindrical element with a protrusion fitted into said aperture, an adjusting screw with an air inlet and locked to said cylindrical element, a ball in contact with said adjusting screw to open or close said air inlet by means of suction inside the cylinder, and a spring interposed between said ball and the protrusion of said cylindrical element.
