ABSTRACT:
An enduring and low-shock inkjet nozzle for an ink cartridge in an inkjet printer is provided. The inkjet nozzle includes a nozzle chip retaining thereon an ink obtained from the ink cartridge, a nozzle plate having thereon a plurality of ink-jetting holes, an energy converting layer converting an external electricity into a heat for vaporizing the ink to be jetted out from the ink-jetting holes, a protecting medium for preventing the energy converting layer from direct impact by the vaporized ink unsuccessfully jetted out of the ink-jetting holes, and a shock-absorbing medium mounted between the nozzle chip and the nozzle plate for absorbing a shock caused by the vaporized ink.
