Suction-type composite handpiece and beauty device including same

A beauty device comprising:

• a plurality of suction-type composite handpieces configured to output radio frequency (RF) energy and electrical muscle stimulation (EMS) and fixed to a skin even when held no hand by sucking the skin;
• and
• a main body connected to the plurality of suction-type composite handpieces, the main body configured to:
• adjust pressure and time for the plurality of suction-type composite handpieces to suck the skin based on a predetermined suction pressure pattern, and
• control operations of the plurality of suction-type composite handpieces,
• each of the plurality of suction-type composite handpieces including:
• a suction part having a suction housing configured to suck the skin to inside and massage the skin based on the suction pressure pattern;
• a contact part protruding from a lower outer peripheral surface of the suction housing, and having an edge connected to the suction housing and formed as a curved surface;
• a plurality of RF terminals configured to output RF energy and formed along an edge where an inner surface of the suction housing and a lower surface of the contact part meet, thus preventing RF energy concentration;
• a plurality of EMS terminals configured to output EMS and arranged to cross between the plurality of RF terminals;
• a temperature sensor located inside the suction housing and configured to detect a temperature of the skin sucked into the suction housing;
• and
• a cooling part located inside the suction housing and configured to lower the temperature of the skin sucked into the suction housing,
• wherein the main body is configured to control the plurality of suction-type composite handpieces to output the RF energy and the EMS alternately or simultaneously based on a predetermined pattern without interfering with each other, and
• wherein the plurality of suction-type composite handpieces are arranged in series on the skin to generate a beat effect between the EMSs output respectively from the handpieces.
