Abstract
A nozzle and an electrostatic field induction ink-jet nozzle are disclosed. In accordance with an embodiment of the present invention, the nozzle includes a concave part, which is formed along an outer circumference of the nozzle and in which the outer circumference is adjacent to a liquid discharging surface. The discharging nozzle can minimize the overflow and damping by a liquid during a process of discharging the liquid and thus maintain the discharging performance constant despite an extended operation of the nozzle.
Claims16
A nozzle comprising a concave part formed along an outer circumference surface of the nozzle, the outer circumference surface being adjacent to a liquid discharging surface,
- wherein the liquid discharging surface is a planar surface of the nozzle being in a tube shape, and the outer circumference surface is a side surface extended in a different plane than the planar surface,
- wherein the concave part extends along an entire circumference of the side surface and is parallel to the liquid discharging surface along a longitudinal axis of the nozzle, the concave part being separated from the liquid discharging surface by a portion of the side surface.
An electrostatic field induction ink-jet nozzle configured to discharge ink by using an electrostatic field formed by a difference in electric potential of electrodes, wherein the nozzle comprises a concave part formed along an outer circumference surface of the nozzle, the outer circumference surface being adjacent to a liquid discharging surface,
- wherein the concave part extends along an entire circumference of the side surface and is parallel to the liquid discharging surface along a longitudinal axis of the nozzle, the concave part being separated from the liquid discharging surface by a portion of the side surface.
