Title (EN) LIQUID AGENT APPLICATION DEVICE
(FR) DISPOSITIF D'APPLICATION D'AGENT LIQUIDE
(JA) 液剤塗布装置
Abstract:
(EN) [Problem] To provide a liquid agent discharge device that has a simple configuration and is capable of smoothly discharging a liquid agent. [Solution] A liquid agent application device 10 is provided with: a diaphragm 12 that changes the internal volume of a liquid agent reservoir 11; and a drive unit 13 that is positioned above the diaphragm 12. The drive unit 13 comprises a driving piezoelectric element 20, a vibrating piezoelectric element 21, and a horn 22. The driving piezoelectric element 20 vibrates in response to the application of a first drive voltage signal. The vibrating piezoelectric element 21 vibrates in response to the application of a second drive voltage signal having an amplitude smaller than that of the first drive voltage signal and a frequency higher than that of the first driving voltage signal. The horn 22 vibrates along with the vibrating piezoelectric element 21.
(FR) Le problème décrit par la présente invention est de fournir un dispositif de distribution d'agent liquide qui a une configuration simple et qui est susceptible de distribuer sans à-coups un agent liquide. La solution selon l'invention porte sur un dispositif d'application (10) d'agent liquide qui est pourvu de : une membrane (12) qui change le volume interne d'un réservoir (11) d'agent liquide; et une unité d'attaque (13) qui est positionnée au-dessus de la membrane (12). L'unité d'attaque (13) comprend un élément piézoélectrique d'attaque (20), un élément piézoélectrique vibrant (21) et un avertisseur sonore (22). L'élément piézoélectrique d'attaque (20) vibre en réponse à l'application d'un premier signal de tension d'attaque. L'élément piézoélectrique vibrant (21) vibre en réponse à l'application d'un second signal de tension d'attaque ayant une intensité inférieure à celle du premier signal de tension d'attaque et une fréquence supérieure à celle du premier signal de tension d'attaque. L'avertisseur sonore (22) vibre avec l'élément piézoélectrique vibrant (21).
(JA) 【課題】簡素な構成でスムーズに液剤を吐出可能な液剤吐出装置を提供する。【解決手段】液剤塗布装置10は、液剤貯留部11の内部容積を変化させるダイヤフラム12と、ダイヤフラム12の上に位置する駆動部13とを備える。駆動部13は、駆動用圧電素子20と、加振用圧電素子21と、ホーン22とを有する。駆動用圧電素子20は、第1駆動電圧信号の印加に応じて振動する。加振用圧電素子21は、第1駆動電圧信号よりも振幅が小さく、かつ、第1駆動電圧信号よりも周波数の高い第2駆動電圧信号の印加に応じて振動する。ホーン22は、加振用圧電素子21とともに振動する。
