Patent ID: 8579606

Claim:
A fluid transportation device for transporting a fluid, said fluid transportation device comprising: a valve seat having an outlet channel and an inlet channel; a valve cap disposed on said valve seat, and comprising a tilt structure, a sustaining structure, an inlet valve channel and an outlet valve channel, wherein said outlet valve channel is a conical channel for facilitating said fluid to be flowed from said outlet valve channel to said outlet valve structure; a valve membrane arranged between said valve seat and said valve cap, and having an inlet valve structure and an outlet valve structure, wherein said inlet valve channel and said outlet valve channel are respectively aligned with said inlet valve structure and said outlet valve structure, and a first side of said inlet valve structure is sustained against said sustaining structure; and an actuating module disposed on said valve cap, and comprising a vibration film and an actuator, wherein when said fluid transportation device is in a non-actuation status, said vibration film is separated from said valve cap, so that a pressure cavity with a gradually-increasing depth is defined, wherein when a voltage is applied on said actuator to result in deformation of said actuator, said vibration film connected to said actuator causes a volume change of said pressure cavity, thereby generating a pressure difference to push said fluid, wherein said fluid is introduced into said inlet valve structure through said inlet channel, wherein said sustaining structure is sustained against said first side of said inlet valve structure, so that said inlet valve structure is tilted toward a second side and said fluid is flowed to said pressure cavity through said second side of said inlet valve structure, wherein said fluid is further guided by said tilt structure of said valve cap to be flowed from said pressure cavity to said outlet valve structure, and then flowed out of said outlet channel.
