摘要： An inkjet print cartridge 18 uses at least one groove 64 to supply ink 112 from an ink reservoir 38 to the fluid channel 78, 74, which includes an ink ejection chamber 74, such that foreign particles within the ink supply are filtered out by the grooves 64 so as not to block the fluid channel 74,78, 80. In one embodiment, a barrier layer 62 between a substrate 60 and nozzle member 48 contains the ink ejection chamber 74 which is in communication with a plenum 78 via a flow restrictor 80, such as pinch points. The nozzle member 48 includes an array of orifices 84 and grooves 64. The substrate 60 includes two linear arrays of ink ejection elements 72, such as heater elements, and each orifice 84 in the nozzle member 48 is associated with an ink ejection chamber 74 and ink ejection element 72. A plurality of grooves 64 is likewise associated with each plenum 78. The plurality of grooves 64 in the nozzle member 48 supply ink 112 into each plenum 78, which in turn supplies ink 112 to the ink ejection chamber 74.
摘要翻译： 喷墨打印盒18使用至少一个凹槽64将油墨112从墨水容器38供应到包括喷墨室74的流体通道78,74，使得墨水供应中的外来颗粒被凹槽 64，以便不阻塞流体通道74,78,80。在一个实施例中，衬底60和喷嘴构件48之间的阻挡层62包含喷墨室74，其通过限流器80与增压室78连通 ，如捏点。 喷嘴构件48包括孔口阵列84和凹槽64.衬底60包括诸如加热器元件的喷墨元件72的两个线性阵列，并且喷嘴构件48中的每个孔84与喷墨室74和 多个凹槽64同样与每个气室78相关联。喷嘴构件48中的多个凹槽64将墨水112供应到每个气室78中，从而将墨水112提供给喷墨室74。 IMAGE>
