Title
(DE) SPRITZPISTOLE UND AUTOWASCHMASCHINE DAMIT
(EN) SPRAY GUN AND CAR WASHING MACHINE PROVIDED WITH SAME
(FR) PISTOLET DE PULVÉRISATION ET MACHINE DE LAVAGE DE VOITURE POURVUE DE CELUI-CI
Abstract
(EN) Some embodiments of the disclosure provide a spray gun and a car washer with the spray gun. The spray gun includes a spray gun housing (10) and an operating handle (20), wherein the operating handle (20) is provided on the spray gun housing (10). The spray gun further includes: a spray gun main body (40); a sealing assembly (50), at least a part of the sealing assembly (50) being movably provided in the spray gun main body (40) of the spray gun, and the operating handle (20) being connected with the sealing assembly (50), so as to drive the sealing assembly (50) to move by pulling the operating handle (20), so that the connection and disconnection of the fluid in the spray gun main body is controlled; and a locking switch (30), mounted on the spray gun housing (10) in a position-adjustable manner, the locking switch (30) being located on one side of the operating handle (20) and cooperating with the operating handle (20) in a limiting manner. The sealing assembly (50) includes a partition flange (141) used for cutting off a fluid passage in the spray gun main body (40) and an elastic member (150) connected with the partition flange (141). The elastic member (150) is provided in a retractable way to press the partition flange (141) to a position that cuts off the fluid passage of the spray gun main body (40).
(FR) La présente invention concerne un pistolet de pulvérisation et une machine de lavage de voiture pourvue de celui-ci, le pistolet de pulvérisation comprenant une coque de pistolet de pulvérisation (10) et une poignée d'actionnement (20), la poignée d'actionnement (20) étant disposée sur la coque de pistolet de pulvérisation (10) ; le pistolet de pulvérisation comprend en outre : un ensemble d'étanchéité (50), au moins une partie de l'ensemble d'étanchéité étant disposée de façon mobile dans un corps principal de pistolet de pulvérisation (40) du pistolet de pulvérisation, la poignée d'actionnement (20) étant raccordée à un ensemble d'étanchéité (50) de façon à entraîner le déplacement de l'ensemble d'étanchéité (50) par traction de la poignée d'actionnement (20), de sorte que la connexion et la déconnexion d'un fluide dans le corps principal de pistolet de pulvérisation (40) sont commandées ; et un commutateur de verrouillage (30), monté sur la coque de pistolet de pulvérisation dans un mode à position réglable, le commutateur de verrouillage (30) étant situé d'un côté de la poignée d'actionnement (20) et correspondant à la poignée d'actionnement (20) dans un mode de limitation, l'ensemble d'étanchéité (50) comprenant une bride de séparation (141) utilisée pour séparer un canal de fluide dans le corps principal de pistolet de pulvérisation (40) et une pièce élastique (150) raccordée à la bride de séparation (141) ; et la pièce élastique (150) étant agencée de façon télescopique de façon à presser la position de la bride de séparation (141) qui sépare le canal de fluide du corps principal de pistolet de pulvérisation (40).
