Abstract

Appareil d'éjection de fluide et dispositif d'éjection de fluide, comprenant un premier orifice d'éjection (4), une cavité convergente (3) et plusieurs premiers composants (1) de mise du fluide sous pression, qui sont reliés séquentiellement. Le sens d'éjection de chacun des premiers composants (1) de mise sous pression du fluide converge au même foyer (301) que celui qui est situé dans la cavité convergente (3). L'angle au sommet entre le sens d'éjection du premier composant (1) de mise du fluide sous pression et l'axe central (5) est supérieur à 0° et inférieur à 90°. Comme le sens d'éjection de chaque premier composant de mise du fluide sous pression converge au même foyer, lorsqu'il est utilisé comme pomme de douche, les premiers composants de mise du fluide sous pression éjectent des fluides haute pression, qui entrent en collision au niveau du foyer pour former des gouttelettes à grande vitesse qui ressemblent à une impulsion d'explosion. Le débit de sortie de l'eau est réduit au minimum, tandis que le sébum, la couche cornée et les bactéries sont entièrement nettoyés, avec réalisation d'un massage hydraulique confortable, ce qui économise véritablement l'eau et conserve les ressources en eau.
