Abstract
The invention discloses a needle tubing refill which comprises a refill tube and a refill head. The refill head is internally provided with a refill head inner hole. The inner side of the front end of the refill head inner hole inclines inwards to form a conical end. The taper angle alpha of the conical end is greater than zero degree and smaller than 10 degrees. Six support bases protruding inwards are formed on one cross section of the refill head inner hole and uniformly distributed on the cross section. The protruding height c of each support base is 0.15-0.20 micron. A steel ball is arranged in the refill head inner hole and arranged between the support bases and the conical end. The side faces, facing the conical end, of the support bases and the inner side face of the conical end are in clearance fit with the surface of the steel ball. The distance between the center of the steel ball and the conical end is a, the distance between the center of the steel ball and the top end of the side face, facing the conical end, of each support base is b, and the radius of the steel ball is r; and a is no greater than half the r, and b is no smaller than two thirds the r. According to the needle tubing refill, the gap between the steel ball and the refill head can be effectively reduced, the outflow quantity of printing ink is decreased, and accordingly the problem of ink accumulation is solved.
