The invention provides a device for solving the problem of inking fault of ball-point pen refills and sign pen refills. In the method, an air bag is added at the tail end of a refill to apply one constant air pressure to ink in the refill, the ink is forced to move down and contact a steel ball at the tip of the refill or air between the steel ball and the ink is removed so that the refill is desterilized. The device structurally comprises a housing, a corrugated air bag and an annular refill fixing collar, wherein the corrugated air bag is arranged in the housing, the lower part of the housing is provided with a refill receiving nozzle, the outer part of the refill receiving nozzle is in a conical shape, the lower part of the corrugated air bag is provided with a conical nozzle, the tip of the conical nozzle is aligned to a tube cavity in the center of the refill receiving nozzle, the tail end of the refill is inserted to the tube cavity in the center of the refill receiving nozzle, the tip of the conical nozzle is inserted to a tube cavity at the tail of the refill, and the refill fixing collar is sleeved outside the refill receiving nozzle to fix the tail of the refill in the refill receiving nozzle. The method in the invention can be used for conveniently eliminating the phenomena that due to the inking stop of the refill, the refill containing a large amount of ink is thrown away to result in waste and environmental pollution, thereby being beneficial to saving resources and protecting environment.
