PROBLEM TO BE SOLVED: To provide a liquid atomization device capable of suppressing attachment of water to an output shaft of a crushing motor.SOLUTION: A liquid atomization device comprises: a fan motor for sucking air into a body case a primary heat exchanger for heating sucked air in the body case and blowing it a humidification unit for crushing water into fine water particles on the basis of an operation of a crushing motor, humidifying the hot air by the water particles and blowing it out of the body case. The humidification unit comprises: a lifting pipe for winding up water from a water storage part by rotating on the basis of the operation of the crushing motor a centrifugal crushing disk rotated integrally with the lifting pipe and scattering the water wound up by the lifting pipe in a rotation direction of the lifting pipe a crushing wall disposed at one side of the centrifugal crushing disk and colliding the water droplets scattered from the centrifugal crushing disk and crushing them into water particles and a shielding member 36 for shielding an output shaft 22 of the crushing motor 17 from the crushed water particles.COPYRIGHT: (C)2015,JPO&INPIT【課題】破砕モータの出力軸への水の付着を抑制し得る液体微細化装置を提供する。【解決手段】本体ケース内に空気を吸い込むファンモータと、吸い込まれた空気を本体ケース内で温めて送風する一次熱交換器と、破砕モータの作動に基づいて水を細かな水粒に破砕し、該水粒で温風を加湿して本体ケース外に送風する加湿ユニットとを備えた液体微細化装置において、加湿ユニットは、破砕モータの作動に基づいて回転して貯水部から水を巻き上げる揚水管と、揚水管と一体に回転され、該揚水管で巻き上げた水を該揚水管の回転方向に飛散させる遠心破砕円板と、遠心破砕円板の一側に配設され、該遠心破砕円板から飛散された水滴を衝突させて水粒に破砕する破砕壁とを備え、破砕モータ17の出力軸22を、破砕された水粒から遮断する遮断部材36を備えた。【選択図】図4
