Abstract: The present invention is related to a liquid heat-dissipating module, for dissipating the heat generated by a heating element, at least comprising: a heat-absorbing unit, being connected with the heating element, for absorbing the heat generated by the heating element; a fluid delivery device, for delivering a fluid, the fluid delivery device being stacked with the heat-absorbing unit and having a heat-dissipating structure; and a connecting pipe, being connected with the heat-absorbing unit and the fluid delivery device for delivering the fluid into the heat-absorbing unit, so as to absorb the heat of the heat-absorbing unit; the fluid absorbing the heat is then delivered back to the fluid delivery device, letting the heat-dissipating structure to dissipate the heat contained in the fluid.

Abstract: An ink-jet cartridge adapted to be used for a thermal ink-jet printer is disclosed. The ink-jet cartridge includes a housing for storing the ink in an interior thereof, a printhead having a plurality of orifices thereon for allowing the ink to be Jetted therethrough when the thermal ink-jet printer is printing, and a pressure-adjusting device disposed in the housing for regulating a back pressure of the interior of the housing, wherein the pressure-adjusting device includes a first opening fixed on an upper portion of the housing and exposed to an ambient atmosphere, and a second opening disposed at a bottom of the interior of the housing and having at least one regulating hole thereon. Each regulating hole has a cross-sectional area being smaller than that of the first opening for maintaining the back pressure when the ink-jet cartridge is inverted.

Abstract: A fragrant ink is provided. The fragrant ink comprises an alcohol component, an imaging component, a fragrant agent component, and a deionized water component. In certain embodiments, the fragrant ink further comprises an ethanol component. The imaging component includes at least one of a soluble dye or pigment materials. The fragrant agent preferably includes a phenolic compound. The fragrant ink causes the paper on which it is printed to emit a pleasant scent.

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.

Abstract: A method is provided for judging whether an ink-containing medium which is used for absorbing an ink is applicable to an ink cartridge. The method includes steps of (a) getting a first value A of a physical parameter of the ink-containing medium, (b) immersing the ink-containing medium into an ink container containing the ink under an immersion temperature for an immersion time, (c) washing the ink-containing medium, (d) drying the ink-containing medium under a dry temperature and a dry pressure, (e) getting a second value B of the physical parameter of the ink-containing medium, (f) calculating a relative change of the physical parameter of the ink-containing medium from the values of the physical parameters of the ink-containing medium, and (g) rejecting the ink-containing medium when the relative change of the physical parameter of the ink-containing medium is larger than a specific value.
