Title
(EN) LIQUID DROPLET PRODUCTION APPARATUS
(FR) APPAREIL DE PRODUCTION DE GOUTTELETTES DE LIQUIDE
Abstract
(EN)
A liquid droplet production apparatus (1) comprising a perforate membrane (50) and an actuator (30) is provided. The actuator(30) is configured to vibrate the perforate membrane (50) such that a liquid in contact with the perforate membrane (50) during use is caused to pass through at least one aperture of the perforate membrane and to be ejected as liquid droplets from the perforate membrane (50). The perforate membrane (50) includes one or more stiffening structures (60) for increasing the stiffness of the perforate membrane (50), the one or more stiffening structures (60) each being defined by a local transverse deformation (60) of the perforate membrane (50). A removable cartridge, a perforate membrane, and an actuator assembly for use in such a liquid droplet delivery apparatus are also provided, along with a method of manufacturing a perforate membrane for such a liquid droplet apparatus.
(FR)
L'invention concerne un appareil de production de gouttelettes de liquide (1) comprenant une membrane perforée (50) et un actionneur (30). L'actionneur (30) est conçu pour faire vibrer la membrane perforée (50) de telle sorte qu'un liquide en contact avec la membrane perforée (50) pendant l'utilisation soit amené à passer à travers au moins une ouverture de la membrane perforée et à être éjecté sous la forme de gouttelettes de liquide à partir de la membrane perforée (50). La membrane perforée (50) comprend une ou plusieurs structures de raidissement (60) pour augmenter la rigidité de la membrane perforée (50), la ou les structures de raidissement (60) étant chacune définie par une déformation transversale locale (60) de la membrane perforée (50). L'invention concerne également une cartouche amovible, une membrane perforée et un ensemble actionneur destinés à être utilisés dans un tel appareil de distribution de gouttelettes de liquide, ainsi qu'un procédé de fabrication d'une membrane perforée pour un tel appareil à gouttelettes de liquide.
