Fluid transportation device

A fluid transportation device for transporting a fluid, comprising:

• a valve main body having a first assembling surface, comprising an inlet passage and an outlet passage respectively communicated with an inlet opening and an outlet opening on the first assembling surface;
• a valve chamber base having a second assembling surface and a third assembling surface, comprising an inlet valve passage and an outlet valve passage, wherein the inlet valve passage and the outlet valve passage are penetrating through the second assembling surface and the third assembling surface, the third assembling surface is partially sunken to form a compressible chamber which is communicated with the inlet valve passage and the outlet valve passage;
• a valve membrane having two valve plates, wherein a plurality of extension brackets are disposed around peripheries of the valve plates to provide elastic support, a hollow hole is formed between each two of the adjacent extension brackets, and the inlet valve passage and the outlet valve passage of the valve chamber base are correspondingly closed by the valve plates within two penetration regions of the valve membrane, in which each of the valve plates forms a valve switch structure;
• an actuator assembled by a vibration plate and a piezoelectric element, wherein the vibration plate has a first surface and an opposing second surface, the piezoelectric element is attached on the first surface of the vibration plate, and the second surface of the vibration plate covers the compressible chamber of the valve chamber base, wherein a plurality of penetration holes and a plurality of opening portions are disposed on the vibration plate where a plurality of electrically conductive locking elements are penetrating through and be contacted therein, so that the locking elements are serving as a plurality of electrode leads of the vibration plate and the conductive area of the vibration plate is increased, wherein the piezoelectric element has an electrode lead;
• a cover body made of a metal, covering the vibration plate of the actuator and in contact with the vibration plate by a large area, wherein a plurality of screw holes are penetrated through the cover body, and two lead grooves are recessed respectively on two perpendicular surfaces of the cover body that are vertically communicated with each other;
• wherein the valve main body, the valve chamber base and the vibration plate respectively have a plurality of penetration holes in which the corresponding penetration holes are aligned with each other and corresponding to the screw holes of the cover body, the electrically conductive locking elements are correspondingly penetrated through the penetration holes to be locked with the corresponding screw holes, and a plurality of lead grooves respectively disposed on the vibration plate, the valve main body and the valve chamber base are corresponding to the two lead grooves of the cover body, and the electrode lead of the piezoelectric element is embedded into the two lead grooves of the cover body and embedded into the lead grooves of the vibration plate, valve main body and the valve chamber base, so that the fluid transportation device is assembled.
