Title (EN) NOZZLE HEAD AND ELECTROSPINNING DEVICE
(FR) TÊTE À BUSES ET DISPOSITIF D'ÉLECTROFILAGE
(JA) ノズルヘッド、および電界紡糸装置
Abstract:
(EN) The problem to be addressed by the present invention is to provide a nozzle head and an electrospinning device in which the nozzle head can be miniaturized and the driving voltage can be reduced. This nozzle head (2) is provided with: a main body part (22) having a space (22b) thereinside that is capable of accommodating a raw liquid; a first nozzle group (12a) that is connected to the main body part (22) and includes at least one nozzle (20); and a second nozzle group (12b) that is connected to the main body part (22) and includes at least one nozzle (20). The nozzle (20) belonging to the second nozzle group (12b) extends in a direction which is gradually away from the nozzle (20) belonging to the first nozzle group (12a) toward the tip side as viewed from the direction in which the main body part (22) extends.
(FR) La présente invention a pour objet une tête à buses et un dispositif d'électrofilage dans lequel la tête à buses peut être miniaturisée et la tension de commande réduite. Une telle tête à buses (2) comprend : une partie de corps principal (22) contenant un espace (22b) susceptible de recevoir un liquide brut ; un premier groupe de buses (12a) relié à la partie de corps principal (22) et comprenant au moins une buse (20) ; et un second groupe de buses (12b) relié à la partie de corps principal (22) et comprenant au moins une buse (20). La buse (20) faisant partie du second groupe de buses (12b) s'étend dans une direction qui s'éloigne progressivement de la buse (20) faisant partie du premier groupe de buses (12a) vers le côté pointe, telle qu'observée depuis la direction dans laquelle s'étend la partie de corps principal (22).
(JA) 本発明が解決しようとする課題は、ノズルヘッドの小型化と駆動電圧の低減とを図ることができるノズルヘッド及び電界紡糸装置を提供することである。 本発明のノズルヘッド(2)は、原料液が収納可能な空間(22b)を内部に有する本体部(22)と、前記本体部(22)と接続され、少なくとも1つのノズル(20)を含む第1のノズル群(12a)と、前記本体部(22)と接続され、少なくとも1つのノズル(20)を含む第2のノズル群(12b)と、を備えている。前記本体部(22)が延びる方向から見て、前記第2のノズル群(12b)に属する前記ノズル(20)は、先端側になるに従い前記第1のノズル群(12a)に属する前記ノズル(20)から離れる方向に延びている。
