摘要： An inkjet print head having a dummy ink chamber and a dummy heater disposed in the inkjet print head such that air bubbles gathered at edges of an ink feed hole are pushed toward an inner side of the ink feed hole when inks are sprayed. Accordingly, although air bubbles caused by the air introduced from an exterior or separated from inks are gathered at the edges of the ink feed hole, the air bubbles are forcedly pushed toward the center portion of the ink feed hole communicating with an ink storage container such that the air bubbles can flow into the ink storage container. Thus, inks are easily supplied to ink chambers adjacent to the edges of the ink feed hole, so that missing nozzles can be prevented from being generated.
摘要翻译：一种喷墨打印头，其具有设置在喷墨打印头中的虚拟墨水室和虚拟加热器，使得当喷墨时聚集在墨水供给孔的边缘的气泡被推向墨水供给孔的内侧。因此，虽然由从外部引入的或与油墨分离的空气引起的气泡聚集在供墨孔的边缘处，但气泡被迫推向与墨水容器连通的供墨孔的中心部分，气泡可以流入储墨容器。因此，油墨容易地供应到与供墨孔的边缘相邻的油墨室，从而可以防止产生缺失的喷嘴。
