Background technology
Printer is widely used in all kinds of occasions, especially office, and printer comprises shower nozzle. Existing nozzle structure, by applying potential pulse to resistance heater, causes temperature to raise, and produces bubble around resistance heater, and then produces ink droplet.
Tradition spray orifice is generally single material, for example, be hydrophilic material, that is to say that its hydrophobicity is inadequate, causes spray orifice residual ink accumulation around, thereby cause the skew of ink droplet emission angle after printing a period of time, affects print quality.
If spray orifice is hydrophobic material, that is to say that hydrophily is inadequate, in meeting build-up of pressure chamber, residual air cannot effectively be discharged, and affects spray orifice and normally works. Tradition ink gun in use the ink in pressure chamber in negative pressure state, to ensure that ink can be not excessive under the state of not printing, due in actual print procedure, negative pressure in pressure chamber has unstability, when the absolute value of negative pressure in pressure chamber exceedes the attraction that ink and cavity inner wall capillarity produce, ink in pressure chamber can sucked back ink feed passage, causes spray orifice cannot produce ink droplet. After ink droplet tranmitting frequency is decided by the transmitting of each ink droplet, ink refluxes the time of filling up pressure chamber, and it is longer that the poorer ink of hydrophily of spray orifice inwall is back to time of pressure chamber, causes ink droplet tranmitting frequency lower.
In addition, if the outer wall in single material applies hydrophobic film, the thickness typical thickness of described hydrophobic film is less than 1um, much smaller than the thickness of spray orifice material layer, the consequence that this structure can cause is: outer wall is cleaned in wiping process, easily outer wall is caused to wearing and tearing, thus the hydrophobicity of losing.
