Liquid ejection head with nozzles ejecting liquid from a pressure generation chamber
View Patent ↗In accordance with an embodiment, a liquid ejection head comprises a pressure generation chamber in which liquid is filled; a plate configured to connect with the pressure generation chamber and include a plurality of liquid ejection sections of which the axes are directed to the center direction of an impact area of the liquid; and a driver configured to enable a pressure in the pressure generation chamber to fluctuate.
1. A liquid ejection head, comprising:
a pressure generation chamber in which liquid is filled;
a plate configured to connect with the pressure generation chamber and including a plurality nozzles as liquid ejection sections each with an axis directed to a center direction of an impact area of the liquid; and
a driver configured to enable a pressure in the pressure generation chamber to fluctuate.
2. The liquid ejection head according to claim 1 , wherein
the axis of each of the plurality of nozzles is directed to a center direction of an impact area of the liquid and intersects with each other.
3. The liquid ejection head according to claim 2 , wherein
the axis of each of the plurality nozzles is a line connecting a center of gravity of area at an inlet side of each of the plurality of liquid ejection sections with a center of gravity of area at a corresponding outlet side of each of the plurality of liquid ejection sections.
4. The liquid ejection head according to claim 1 , wherein
the axis of each of the plurality of nozzles is a line connecting a center of gravity of area at an inlet side of each of the plurality of liquid ejection sections with a center of gravity of area at a corresponding outlet side of each of the plurality of liquid ejection sections.
5. The liquid ejection head according to claim 1 , wherein
the axis of each of the plurality of nozzles is directed to a direction in which the liquid respectively to be ejected from the plurality of nozzles is impacted on the impact area while approaching each other.
6. The liquid ejection head according to claim 1 , wherein
the axis of each of the plurality of nozzles is directed to a direction in which the liquid respectively to be ejected from the plurality of nozzles is coalesced and impacted on the impact area.
7. The liquid ejection head according to claim 1 , wherein
an interval between each of the plurality of nozzles is shorter than a diameter of each nozzle.
8. The liquid ejection head according to claim 1 , wherein
a depth of a nozzle plate is thicker than a diameter of each nozzle.
