Patent WO-03106896-A1 (WO)
Title: Briquet produisant une decharge haute tension
Inventor: HUANG XINHUA
IPC: F23Q2/28
Filed: 2003-04-08
Abstract: La présente invention concerne un briquet capable de produire une décharge
haute tension comporte un réservoir à combustible, un mécanisme
piézo-électrique, et un mécanisme de débit de gaz. Un
éteignoir ventilé recouvre le mécanisme de débit de gaz.
Le mécanisme piézo-électrique comprend un dispositif piézo-électrique,
un bouton-poussoir, et un fil conducteur. Le dispositif piézo-électrique,
le bouton-poussoir, et le fil conducteur sont solidaires les uns des autres.
Le fil conducteur est fixé par une extrémité au dispositif piézo-électrique,
et par l'autre extrémité à l'électrode haute
tension. Dans l'éteignoir ventilé, un conducteur connecté
à une molette ferme l'électrode haute tension. La molette est
solidaire d'un ressort exerçant une force et encerclant le mécanisme
de débit de gaz. La présente invention, qui est de structure simple,
est simple à mettre en oeuvre. Tant que l'utilisateur ne fait pas tourner
la molette, la décharge électrique ne se produit pas, même lorsque
le bouton-poussoir est appuyé, ce qui fait que le gaz ne peut pas s'allumer
par mégarde.
