Patent ID: 7195603

Claim:
A supersonic beauty treatment device, comprising: a casing having a socket and being equipped with an AC high-frequency power supply which enables selecting a set of oscillating frequency and power; a large head having a plug, which is detachably fixed to said socket, and a supersonic vibrator that oscillates by low-frequency and large power; and a small head having a plug, which is detachably fixed to said socket, and a supersonic vibrator that oscillates by high-frequency and small power, wherein: each of said plugs has electrically conductive electrodes, and said socket has sets of contacts which are unique to said electrodes of each plug and are closed or opened by said electrodes; and either of said heads is installed with said casing for electrically connecting said AC high-frequency power supply to said respective supersonic vibrator, whereby switching the set of oscillating frequency and power of said AC high-frequency power supply with closing or opening one set of said contacts by said electrodes in each plug provides the large head with low-frequency and large power and the small head with high-frequency and small power.
