Abstract An ink injection device includes an ink storage device with an ink injection hole and an air guide hole, an ink injection seat containing base and ink injection hole and a pressure generation device, in which the said ink injection device also includes an ink absorbing seat with base and air extraction hole; on said base, the ink absorbing seat is aligned with ink outlet of the described ink box, and is communicated with the described pressure generation device, and also includes a residual ink receiving tube communicated with said ink absorbing seat. When the positive pressure from air source is applied to said ink storage device, the ink can be injected into ink box device, and when the negative pressure from air source is applied to the ink box device placed on the described ink absorbing seat, it can eliminate the positive pressure in said ink box, so that it utilizes positive and negative pressures to eliminate bubble in the ink box device.
