Abstract

Une structure améliorée de pulvérisateur à déclencheur manuel en plastique pur comprend une partie de tête de pompe et une partie de corps de pompe. La partie de tête de pompe comprend une coiffe (1), une tête de détournement d'eau (2) et une soupape de guidage (3). La partie de corps de pompe comprend un corps principal (4), un couvercle (5), un ressort en plastique (6), un piston (7), une gaine de ressort (8), un couvercle fermé (9), un grand anneau (10), une entretoise (11), un petit couvercle fermé (12), une gaine de tuyau d'aspiration (13), un tuyau d'aspiration (14) et un déclencheur (15). Le déclencheur est fixé par le biais de son trou de fixation (1501) qui est attelé à la tige du déclencheur (401) du corps principal et est bouclé sur le piston. Ainsi, le déclencheur réalise un mouvement de glissement en arc de cercle autour de la tige du déclencheur fixée, et le mouvement de glissement en arc de cercle du déclencheur est converti en mouvement de glissement horizontal du piston lorsqu'une main presse le déclencheur. Selon l'invention, le ressort en plastique (6) est disposé entre le corps de cylindre du corps principal (4) et le piston (7). Le déclencheur présentant la structure améliorée peut être assemblé facilement et recyclé de manière à respecter l'environnement grâce à sa structure simple et à sa longue durée de vie.
