PROBLEM TO BE SOLVED: To provide a fine bubble generation device which generates various hot bath effects.SOLUTION: A bathing agent storage container (3) is arranged on a suction side channel of a vane pump (1) and a solid foaming agent (7) is dissolved on an inner part thereof. According to dissolution, various hot bath effect components such as carbon dioxide gas and plant-derived essential oil components or degrading enzymes are exhibited, the exhibited components, air (a general term of gas) and hot water are pressurized and mixed to make a gas-liquid dissolution liquid of nearly saturated state and, thereafter, according to sudden pressure release, fine bubbles containing the hot-bath effect component are formed.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】 多様な温浴効果を発生させる微細気泡発生装置【解決手段】 ベーンポンプ(1)の吸込側流路に入浴剤収容容器(3)を配設し、内部で固形発泡剤(7)を溶解させる。溶解によって内部には炭酸ガスや植物由来の精油成分又は分解酵素等様々な温浴効果成分が発現し、発現した該成分と空気(気体の総称)と湯水は加圧混合されて略飽和状態の気液溶解液になった後、急激な圧力解放によって、前記温浴効果成分含有の微細気泡となる。【選択図】図1
