(Cl. 12S- 40) ABSTRACT F THE DISCLOSURE A cosmetic massage device has upper and lower casings which are connected by an adjusting ring. An iron core with a coil is in the lower casing cooperating with an armature connected to an elastic plate secured in the upper casing. Movement of the armature causes expansion and contraction of an air chamber with suction and exhaust valves. The air chamber is connected to a vacuum chamber `surrounded by an elastic element for contacting the skin. Operation of the coil by A.C. causes vibration of the armature and suction within the vacuum chamber to remove dirt, dust and other substances from the pores of the skin by vacuum.

The present invention relates to a cosmetic massage device which is adapted to massage on the skin of the face while locally applying a vacuum pressure.

An object of the present invention is the provision that after washing the face by means of cleansing cream the dust, secreting substance and fatty substance still remaining in the pores of the skin may be further removed.

Another object of the present invention is the provision that by applying a negative pressure externally of the peripheral blood vessels to make them expand, the blood flow may be improved, or by facilitating the amino acid, lymph, leucocyte, old erythrocyte, etc. contained in the blood within the peripheral blood vessels to permeate therethrough, the in'herent function of the peripheral blood vessels may be enhanced, and thereby the creation of wrinkles or spots on the face may be precluded or they may be removed.

Further object of the present invention is the provision that the surface of the skin may be smoothed and made apt to have cosmetics extended thereon when applied, and also that the surface after applied with the cosmetics may become smooth and beautiful.

Still further object of the present invention is the provision that one who wants to make up may easily use the ,device by oneself and also may simply use the device every day while looking at oneself in a mirror each time one makes up.

Another object of the present invention is the provision that the vacuum generating device may he extremely simplied, especially, without employing the relatively expensive electric motor, the valve means of the vacuum pump may be simplified and yet the operation of the valve may be assured.

Still another object of the present invention is the provision that the device is not only adaptable for cosmetic use but also it serves to accelerate the function of the peripheral blood vessels in the proximity of the skin surface.

In the drawings, an upper casing is shown at 1, a lower casing is shown at 2, the lower casing 2 having a recess 3 formed around its upper end, into which recess is loosely tted an expansion and contraction adjusting ring 4, and around the lower end of the upper casing 1 are provided screw threads 5 so that the threads 5 may be threadably engaged with screw threads 6 of the expansion and contraction adjusting ring 4.

In this connction, guide bores 1 drilled in the upper casing 1 are slidably engaged with guide rods 2 projecting from the lower casing 2.

The combined shape of the upper casing 1 and the lower casing 2 is somewhat similar to an egg-like shape, and the size of the combined casings is such that it may be grasped in a single hand.

An iron core is shown at 7, on which acoil 8 is wound, terminals of thecoil 8 being shown at 8', and these terminals are adapted to receive terminals of a power supply cord (not shown).

A strong-weak transfer switch is shown at 9 which is adapted to regulate the magnetic force of thecoil 8.

A thin elastic metal plate is shown at 10, which is xedly secured within the upper casing 1 by means ofstud bolts 11. On the upper and flower surfaces of thethin metal plate 10 are respectively lixed afixture 12 and a connectingrod 13, anarmature 14 being secured to the lower end of the connectingrod 13, and thisarmature 14 is opposed to the magnetic poles 7', 7 of the aforementioned iron core 7.

The upper end of thefixture 12 is fixedly secured to the center portion of anelastic disc 15 as of rubber, athick portion 15 is formed along the periphery of theelastic disc 15, anair chamber 16 is defined above the upper surface of the center portion ofdisc 15. On thethick portion 15 is superposed a disc-shapedelastic suction valve 17 having ahole 19 drilled therethrough, this elastic suction Valve 17 is caused to make a tight surface contact with the lower surface of theupper end wall 18 of the upper casing 1, and theelastic suction valve 17 and theelastic disc 15 are xedly secured to theupper end wall 18 by means ofstud bolts 33.

In thefixture 12 is provided an L-shaped exhaust hole 20, one end of the exhaust hole being open to the inside of theair chamber 16, the other end being open to the outside of theair chamber 16, at opening 20' and thefixture 12 is pressed an exhaust valve consisting of arubber sleeve 22.

Onto :the upper surface of theupper end wall 18 is threadably secured asuction element 21 by the intermediary of apacking 21.

Thesuction element 21 consists of a mounting portion 32 formed of rigid material and a skin contacting portion 23 formed of elastic material. On the upper surface of the center portion of this element is provided avacuum chamber 24 having a large aperture, and on the lower surface is provided asuction hole 25 so that saidsuction hole 25 may communicate with another suction hole 26 drilled through theupper end wall 18 of the upper casing 1.

On the other hand, the suction hole 26 and thehole 19 drilled through theelastic suction valve 17 are staggered in position, and these holes are blocked from each other by means of theelastic suction valve 17 therebetween.

Upon using this cosmetic cleaner, the terminals 8' are connected through a cord, for instance, to a home power supply such as, for example, an A.C. power source having a frequency of 50 or 60 c.p.s. and a voltage of 100 or 200 v., theswitch 9 is turned on to supply said A.C. power to thecoil 8, and thus the skin contacting portion 23 of thesuction element 21 is brought onto the skin S of the surface and rubbed thereon according to the known method of massage.

Then a tractive force is intermittently exerted upon the magnetic pole 7 of the iron core 7 in synchronization with the frequency of the afore-mentioned A.C. power source.

Consequently, thearmature 14 approaches to the magnetic pole 7 against the elastic force of themetal plate 10 and the resistance of theelastic disc 15, and then the various portions take the state shown in FIG. 2.

In other words, theair chamber 16 expands in volume resulting in reduction of its internal pressure to lower than the pressure (atmospheric pressure) of thevacuum chamber 24, and thereby the air in thevacuum chamber 24 pushes theelastic suction valve 17 downwardly through thesuction holes 25, 26, so that the suction hole 26 and thehole 19 may be caused to communicate with each other so as to make air flow into theair chamber 16.

In the next instant, when the tractive force of the magnetic pole 7 becomes ineffective at the point of inversion of the direction of current of the power source, thearmature 14 is pulled upwardly by the elastic force of themetal plate 10, so that the various portions coupled thereto may shift from the state shown in FIG. 2 to another state shown in FIG. 3.

More particularly, theair chamber 16 reduces its volume resulting in rise of its internal pressure to higher than the pressure in thesuction chamber 24, and thereby theelastic suction valve 17 is pushed upwardly so that thehole 19 and the suction hole 26 may be blocked from each other by means of theelastic suction valve 17. Therefore, the air within theair chamber 16 will push out therubber pipe 22 through theexhaust hole 20 to open its outlet, and thus the ai-r will escape into the atmosphere.

The motion of thisarmature 14 completes one reciprocation for each time when the A C. power source changes the direction of its current, and therefore if an A.C. power source of 60 c.p.s. is employed, thearmature 14 will vibrate at the rate of 120 c.p.s.

By turning the expansion and contraction adjusting ring 4, the gap space between the upper casing 1 and the lower casing 2 may be varied and simultaneously the gap space between the magnetic pole 7' and thearmature 14 may be either increased or decreased, so that the amplitude of vibration of thearmature 14 and theelastic disc 15 integrally coupled thereto may be adjusted to regulate the degree of vacuum in thevacuum chamber 24. By the way, this amplitude of vibration is preferably about 4 mm.

In this way, the inner space of thevacuum chamber 24 is evacuated, and the skin S opposed to thevacuum chamber 24 upheaves somewhat into a hill shape.

If thevacuum chamber 24 is gradually shifted along the skin under the above-mentioned state, the hill-shaped upheaval will also shift just as a wave propagates, and the skin S which comes outside of the vacuum chamber will be brought back to the original at state.

Then there occurs a phenomenon that the dirt which was blocking the pores located at the hill-shaped upheaved skin portion, is squeezed out from the deep of the pores towards the surface of the skin.

In this way, the dirt squeezed out onto the skin surface, adhere to the inside of the skin contacting portion 23 or to the top surface of the mounting portion 32. Therefore, when the adhered dirts have become a considerable amount, thesuction element 21 is removed from the upper casing 1 and also the skin contacting portion 23 is removed from the mounting portion 32 for cleaning, and then they are reassembled for use.

In the embodiment shown in FIGS. 4 and 5, instead of providing theexhaust hole 20 in thefixture 12 as in the case of FIGS. 1 to 3, anexhaust hole 27 is drilled through theupper end wall 18 of the upper casing 1 and through theelastic suction valve 17, the upper end of thesuction hole 27 being covered by aportion 21" of the packing 21', and anatmosphere communicating hole 28 is formed above thecovering portion 21". As shown in FIG. 4, when the pressure in theair chamber 16 is reduced, theexhaust hole 27 is closed by the exhaust valve utilizing theportion 21 of the packing 21', and theelastic suction valve 17 is opened to suck up the air within thevacuum chamber 24 into theair chamber 16. As shown in FIG. 5, when the pressure in theair chamber 16 is enhanced, theelastic suction valve 17 is closed and theportion 21" of the packing 21' is forcibly opened to communicate theexhaust hole 27 with theatmosphere communicating hole 28, and thereby the air within theair chamber 16 is exhausted into the atmosphere. With regard to other portions, the embodiment in FIGS. 4 and 5 is similar to that shown in FIGS. l to 3.

Still further in the embodiment shown in FIGS. 6 and 7, in contrast to the fact that theexhaust hole 20 is pro vided in thefixture 12 in the case of FIGS. 1 to 3, anexhaust hole 29 is drilled through theelastic disc 15, beneath theelastic disc 15 is tightly overlapped an exhaust valve consisting as ofrubber disc 30, and anatmosphere communicating hole 31 is drilled through thisrubber disc 30 so that theexhaust hole 29 and theatmosphere communicating hole 31 are communicated with each other. As shown in FIG. 6, when the pressure in theair chamber 16 is reduced, theelastic valve 17 is opened to make the air within theair chamber 24 flow into theair chamber 16 similarly to the embodiment shown in FIGS. 1 to 3, and during this period the ex' haust valve consisting of therubber disc 30 keeps a tight contact state with theelastic disc 15 so as to close theexhaust hole 29 and theamtosphere communicating hole 31.

As shown in FIG. 7, when the pressure in theair chamber 16 is increased, the elastic suction Valve 17 closes to block the .suction hole 26 and the hole .19, and consequently therubber disc 30 is pushed downwardly to create a gap clearance between theelastic disc 15 and therubber disc 30, through which the air in theair chamber 16 is exhausted into the atmosphere. With respect to other portions, the embodiment in FIGS. 6 aud 7 is almost similar to that shown -in FIGS. l to 3.
