The present embodiment relates to a fluid delivery structure and a fluid delivery device, which can be applied to reagent manufacturing or testing, and more particularly to a micro-liquid printing device used in the fields of biomedicine, biochemistry or molecular biology.

Referring to FIG. 1 and FIG. 2A to FIG. 2B together, a fluid transporting structure 10 of the present invention is suitable for transporting fluids for printing (pointing) operations. The fluid transport structure comprises: a strip body 12, a lateral groove 14 and a longitudinal section groove 16, wherein the strip body 12 can be made of a hard material or a soft material.

As shown, the strip body 12 is formed at the bottom end to form a cone 20 from the outside to the inside, and a second port 22 is formed at the tip end of the cone 20. The cone 20 is not limited to a circular or angular vertebral body, and as long as it has a shape gathered toward a tip, the cone 20 is the embodiment, and the cone 20 is strip-shaped. A portion of the body 12, non-separating structure, is described herein in combination.

Next, the lateral groove 14 is disposed at the tip end of the tapered body 20, and the longitudinal groove 16 is also disposed at the tip end of the tapered body 20 and intersects the lateral groove 14. Furthermore, the longitudinal sectioning groove 16 is connected to a first port 18 and the second port 22 such that liquid can flow or be stored between the first port 18 and the second port 22. The first port 18 is located in the strip body 12 or on the outer surface. The longitudinal sectioning groove 16 is disposed through the tapered body 20, and the two ends of the longitudinal sectioning groove 16 are respectively communicated with the first port 18 and the second port 22, so that when liquid is taken, the liquid can quickly enter the longitudinal direction. Within the gully 16 . Further, at the first port 18, a liquid storage area 181 can be further connected, the liquid storage area 181 having a width slightly larger than the width of the longitudinal slit 16 for liquid storage.

Accordingly, by the arrangement of the lateral grooves 14 and the longitudinal grooves 16, when the tip of the cone 20 hits the object to be printed (the carrier), the liquid will follow the direction of the lateral groove 14 and the longitudinal groove 16. The flow spreads out so that the contact surface that causes the liquid to be printed on the carrier is nearly circular.

Further, the lateral grooves 14 may be provided with a plurality of strips, for example as shown in FIG. 2C, and intersect each other to form an approximately square-shaped appearance (if the number of the lateral grooves 14 is larger, it is not limited to Approx. m-shaped), so that after the liquid flows out, it is easier to form a circular liquid as shown in FIG. 7 on the carrier.
