Abstract: This utility is concerned with an improvement in a breast massager equipped with a steam generator and a set of suction generator. The half part of the breast cup of said massager is designed to have double walls separated between and the space surrounded by said walls forms a vapor room. The internal wall of said breast cup facing the breast is all over bored with a plurality of vapor holes through which vapor can run. During operation, a set of suction generator, consisting of a vacuum compressor and a on-off electromagnetic valve controlled by an electronic timer, can operate to suck and release the breast through said breast cup and meanwhile the warm vapor produced by a stream generator can flow into the vapor room penetrating through said holes and spreading over and warming the breast. Therefore, the above-mentioned functioning is surely possible to accomplish the breast beautification.
