Patent ID: 8596558

Claim:
A water gun, comprising: a main body having an intake channel, a turning channel, and an outlet channel connected in sequence for guiding a water flow passing from said intake channel to said outlet channel through said turning channel, wherein said main body comprises a waterproof gasket, which has a penetrating outlet, sealed at and disposed in said outlet channel at a position that one end of said waterproof gasket is projected into said turning channel; and a finger-operated switch, which comprises: a rotating shaft rotatably disposed in said turning channel; a waterproof spacer which is coupled at said rotating shaft and located within said turning channel, wherein said waterproof spacer comprises a curved plate having an outer curved surface sealed at and contacted with an inner wall of said turning channel; and a finger-operated member coupled with said rotating shaft to drive said waterproof spacer between an opened position and a closed position, wherein when said rotating shaft is driven to rotate via said finger-operated member at said opened position, said outer curved surface of said waterproof spacer is slid and moved away from said outlet channel for allowing said water flow passing from said intake channel to said outlet channel through said turning channel, wherein when said rotating shaft is driven to rotate via said finger-operated member at said closed position, said outer curved surface of said water proof spacer is slid and moved to seal at said outlet channel for stopping said water flow to said outlet channel, wherein at said closed position, said waterproof spacer is pushed, via water pressure within said turning channel, toward said outlet channel to further seal with said end of said waterproof gasket so as to enhance a water sealing effect of said waterproof spacer; wherein said rotating shaft has a stop groove provided at one side of said rotating shaft, wherein said waterproof spacer further has a long convex which is extended from said curved plate and is mounted at said stop groove of said rotating shaft, wherein a gap is formed between said long convex and said stop groove to allow said waterproof spacer being moved in relative to said rotating shaft.
