PROBLEM TO BE SOLVED: To provide a device for generating a negative ion, the device that can be used in a bath in a household and that is useful for health and beautification by activating "somatids" of the human body.SOLUTION: Air is applied to a mineral housing device 1 containing an ion ball 13 for which tourmaline ore, obsidian and a phosphate mineral are mixed, with a generated negative ion neutralized in oxygen and hot water in a bath. The negative ion is absorbed through a breathing, a mouth, a nose, a skin, etc., in the bath, with an immune strength produced in the "somatids" of the body, making perspiration possible at low temperature, and serving a useful purpose in health and beautification.COPYRIGHT: (C)2014,JPO&INPIT【課題】家庭の風呂で使用でき、人体の(ソマチット)を活性化させることにより、健康と美容にに役立つ、マイナスイオン発生器具を提供する。【解決手段】トルマリン鉱石、黒曜石及び、リンサンエン鉱物を混合したイオンボール13を含む鉱石収納装置1にエアーを送り、発生したマイナスイオンを酸素および風呂の湯に中和させる。マイナスイオンは入浴しながら呼吸・口・鼻・皮膚、等から吸収されて人体の(ソマチット)に免疫力がつき、低温で発汗でき、健康と美容に役立つ。【選択図】図-1
