Title (EN) LIQUID EJECTION HEAD TO BE USED FOR INHALER AND INHALER
(FR) TÊTE D'ÉJECTION DE LIQUIDE À UTILISER POUR UN INHALATEUR ET INHALATEUR
Abstract:
(EN) A liquid ejection head has a plurality of liquid ejection ports(10) and a plurality of gas jet ports(11) that are arranged alternately. The liquid droplets ejected from the liquid ejection ports(10) are prevented from colliding with each other and can maintain a uniform particle size distribution as gas is jetted out from the gas jet ports(11) in a direction same as the direction in which liquid droplets are ejected from the liquid ejection ports(10).
(FR) L'invention porte sur une tête d'éjection de liquide qui a une pluralité d'orifices d'éjection de liquide (10) et une pluralité d'orifices d'éjection de gaz (11) qui sont disposés en alternance. Les gouttelettes de liquide éjectées à partir des orifices d'éjection de liquide (11) sont empêchées d'entrer en collision l'une avec l'autre et peuvent maintenir une distribution de dimension de particules uniforme lorsque le gaz est éjecté des orifices d'éjection de gaz (11) dans une direction identique à la direction dans laquelle les gouttelettes de liquide sont éjectées des orifices d'éjection de liquide (10).
