Abstract

L'invention concerne un pistolet pulvérisateur de poudre doté d'un circuit intégré incorporé. Le pistolet comporte un corps (1) de pistolet, un couvercle arrière (10) destiné au corps (1) de pistolet, des tubes (12) d'affichage numérique et une molette (13) de réglage de tension. L'extrémité du corps (1) de pistolet comprend une cavité (17) ouverte à son extrémité et destinée à recevoir un circuit de réglage de tension. Le couvercle arrière (10) est fixé à la cavité (17) ouverte à son extrémité afin d'y fixer le circuit de réglage de tension. Une partie médiane du couvercle arrière (10) comporte un évidement rectangulaire destiné à installer les tubes (12) d'affichage numérique afin d'indiquer la variation de tension. Le couvercle arrière (10) est muni de trous circulaires destinés à installer la molette circulaire (13) reliée au circuit de réglage de tension. Il n'est pas nécessaire de considérer à la fois la commande de l'hôte et du pistolet pulvérisateur de poudre en cours de fonctionnement. En revanche, les fonctions de réglage de tension et d'affichage peuvent être réalisées en ne commandant que le pistolet pulvérisateur de poudre, améliorant ainsi le rendement.
