Abstract

Ce dispositif de génération de gouttelettes à partir d’un liquide comporte un corps creux (1) délimitant une enceinte de génération, des moyens (3,40) de génération de gouttelettes à partir d’un jet de liquide s’écoulant à l’intérieur de ladite enceinte, ces moyens de génération étant pourvus d’au moins un orifice (31) d’admission de liquide et d’au moins un orifice (30) de sortie de liquide, des moyens de diffusion de gouttelettes d’un brouillard, formé à partir dudit jet, ainsi que des moyens de stérilisation dudit liquide. Selon l’invention, les moyens de stérilisation (6) comprennent des moyens de stérilisation par rayonnement ultraviolet, de préférence par rayonnement ultraviolet de type C. Par conséquent le dispositif de l’invention assure une stérilisation fiable du liquide, tout en présentant une structure relativement simple et un coût énergétique peu élevé. Figure 6.
