Abstract

The invention provides a liquid injection device and printing equipment. The liquid injection device comprises a print head and a controller. The controller is used to transmit driving pulse signals to the print head continuously by taking non-ink jet drive pulse waves and ink jet drive pulse waves as drive pulse cycles, and one drive pulse cycle comprises a plurality of non-ink jet drive pulse waves and one ink jet drive pulse wave, and in addition, the number of the non-ink jet drive pulse waves is used to determine a size of an ink jet ink droplet. The print heat is used to generate vibration according to the drive pulse signals, and then pressure waves used to generate the ink droplets are formed in the pressure chamber of the print head, and in addition, the amplitudes of the pressure waves are changed along with the number of the non-ink jet drive pulse waves in the single drive pulse cycle. According to the invention, the number of the non-ink jet drive pulse waves in the single drive pulse cycle is used to determine the sizes of the ink jet ink droplets, and therefore the breakdown of the printing equipment caused by the drive pulse waves having too large signal intensity is prevented, and the service lifetime of the printing equipment is prolonged.
