Abstract

The invention provides a milk box pricking needle assembly and a milk suction method. The milk box pricking needle assembly is provided with a pricking needle; a first oblique cut opening which can pierce a milk box is formed in the lower end of the pricking needle; and a plurality of strip-shaped receding surfaces in the vertical direction are arranged at the end, adjacent to the first oblique cut opening, of the outer wall of the pricking needle in the circumferential direction. When the pricking needle pierces the milk box, the first oblique cut opening pierces the milk box to form a pierced opening in the milk box; and a gap is formed between the receding surfaces and the pierced opening for air to enter, so that the suction is prevented from reducing when the pricking needle sucks milk in the milk box.
