The invention discloses a biomimetic liquid distributor and a manufacturing method thereof. The biomimetic liquid distributor comprises a distributor body. A liquid inlet pipe is arranged in the center of the side wall of the distributor body. Liquid distribution holes are formed in a distribution tray of the distributor body. Each liquid distribution hole is of an inverted cone structure simulating the visceral foramen of an earthworm. Convex bosses are arranged on the distribution tray of the distributor body and are of a structure simulating a dung beetle body. The circumference of each convex boss is tangent to the center connection line of the liquid distribution holes in the two sides of the convex boss. The manufacturing method comprises the following steps that the biomimetic biological prototypes are captured, information of the biomimetic portions of the abdomen of the dung beetle and the visceral foramen of the earthworm is collected, and the obtained information is guided into a computer. According to the biomimetic liquid distributor and the manufacturing method thereof, excellent initial distribution uniformity is achieved, the medium transfer efficiency can be greatly improved, normal operation of the liquid distributor is not affected, and the biomimetic liquid distributor is simple in structure, convenient to manufacture and low in cost.
