摘要： An inkjet printer head includes a substrate having a manifold and an ink channel to supply ink, a nozzle plate formed on the substrate, a chamber formed between the substrate and the nozzle plate and extending toward the substrate and the nozzle plate, an electrode formed at an interface between the substrate and the nozzle plate and around the chamber, and a heater having both ends extending in contact with the electrode to be suspended on the chamber in direct contact with the ink and to generate bubbles from both surfaces thereof. The inkjet printer head is capable of improving manufacturing process efficiency by omitting a process of separately forming a heater passivation layer, operating the heater at low electric power by omitting the heater passivation layer, improving integrity of a nozzle by lowering a working voltage, and improving reliability in manufacturing processes by locating the suspended heater to be in parallel with the substrate and the electrode.

摘要： An inkjet printer head includes a substrate having an ink-feed hole to supply ink stored in a cartridge to an ink chamber and a restrictor in fluid communication with the ink chamber, an oxide layer formed on the substrate, a heater disposed on the oxide layer above the restrictor and having fixed parts disposed on the oxide layer, slopes extending upward and away from the restrictor at an incline, and a parallel part extending between the slopes parallel to the substrate, a lead formed to be in electrical contact with the heater, a chamber layer formed to cover the lead and to define the ink chamber, and a nozzle layer formed on the chamber layer and having a nozzle. In the inkjet printer head, the lifespan of the heater may be extended since the heater is supported by the slopes, which function as a shock absorbing member when ink supply pressure or cavitation force is applied to a surface of the heater. In addition, since the heater does not have a right angle structure, the heater may be formed to have a uniform thickness even when a thin layer used for the heater is formed by a deposition method.
摘要翻译：一种喷墨打印头包括：具有供墨孔的基板，用于将存储在墨盒中的墨水供应到墨室;以及限制器，其与所述墨室流体连通;形成在所述基板上的氧化物层;设置在所述氧化物层上的加热器在限流器上方并且具有设置在氧化物层上的固定部分，倾斜在倾斜处向上延伸并远离限制器，并且平行部分在平行于衬底的斜面之间延伸，形成为与加热器电接触的引线，形成为覆盖引线并限定墨水室的室层，以及形成在室层上并具有喷嘴的喷嘴层。在喷墨打印机头中，加热器的寿命可以延长，因为加热器由斜面支撑，当墨水供应压力或空穴力施加到加热器的表面时，该斜面用作减震构件。此外，由于加热器不具有直角结构，即使当通过沉积方法形成用于加热器的薄层时，也可以将加热器形成为具有均匀的厚度。
