发明名称 Vent for an inkjet printhead
摘要 An inkjet printhead has been developed that includes an ink reservoir vent, which prevents ink from exiting the ink reservoir through the vent. The inkjet printhead includes a reservoir, an ink inlet, a vent opening, and a vent member. The reservoir contains a supply of ink and an air space above the supply of ink. The vent member extends from the vent opening and includes a first vent member opening positioned in an air space outside of the reservoir, a second vent member opening positioned in the air space above the supply of ink, and a vent channel configured to couple fluidly the first vent member opening to the second vent member opening. The second vent member opening is positioned within the reservoir to enable the second vent member opening to remain within the air space above the supply of ink regardless of a printhead orientation.
