Abstract:
A liquid spraying apparatus for equipping with a sanitary tool, comprising:a liquid container for receiving a liquid therein; a gas bag, which is a hollow body made of elastic material for retaining gas therein, being capable of being compressed and retaining to an original shape thereof after a compression applied thereto is released; a T-pipe having a bottom end, an inlet end and an outlet end; a one-way valve connected with said outlet end of said T-pipe that only allows said liquid and gas to be emitted from said spraying nozzle; a spraying nozzle, adapted for mounting to a front portion of said sanitary tool, being connected to said one-way valve; an inlet pipe disposed in said liquid container having an upper end connected to said inlet end of said T-pipe; an inlet valve connected to a lower end of said inlet pipe for disposing in said liquid of said liquid container; and an elongated gas pipe which has one end connected to said bottom end of said T-pipe and another end extended to linked up to said gas bag, wherein said gas pipe is adapted for extending through the sanitary tool for linking said spraying nozzle with said gas bag while said liquid spraying apparatus is installed to said sanitary tool, wherein when a first compression is applied to said gas bag, said gas inside said gas bag is compressed to pass through said T-pipe via said gas pipe to push said one-way valve to open and to exhaust out from said spraying nozzle, wherein said gas also shuts up said inlet valve via said inlet pipe so as to provide an elasticity of said gas bag to return to said original shape after said compression of said gas bag is released, thereafter said liquid in said liquid container is under atmospheric pressure and pushes said inlet valve to open and enters said inlet pipe, wherein said one-way valve is closed and said liquid is absorbed into said gas pipe via said T-pipe, accordingly when a second compression is applied to said gas bag again, said inlet valve is closed and said liquid inside said gas pipe and under a pressure of said gas is forced to spray out from said spraying nozzle, wherein after said second compression of said gas bag is released, said liquid is absorbed into said gas pipe again, therefore by repeatedly compressing and releasing of said gas bag, said liquid received in said liquid container is able to be absorbed and sprayed out through said spraying nozzle via said inlet pipe, said T-pipe and said one-way valve.
