摘要:
A gas purging unit and an inkjet head with the same. The gas purging unit has an exhaust chamber with a connecting hole to communicate with an ink passage and an exhaust hole that communicates with an outside. A gas permeable membrane is installed at the connecting hole. A negative pressure generator is provided inside the exhaust chamber to operate through an external force and generate a negative pressure with less pressure than a pressure inside the ink passage. A check valve is installed at the exhaust hole to open the exhaust hole when the external force operates the negative pressure generator and to close the exhaust hole by a force of the negative pressure after the external force is removed.
摘要(中):
气体吹扫单元和具有该气体净化单元的喷墨头。 气体净化单元具有排气室,该排气室具有与油墨通道连通的连接孔和与外部连通的排气孔。 透气膜安装在连接孔处。 在排气室内设置负压发生器,以通过外力进行操作,并产生比油墨通道内的压力更小的压力的负压。 当外力操作负压发生器时,止回阀安装在排气孔处以打开排气孔,并且在去除外力之后通过负压力关闭排气孔。
