In accordance with an embodiment of the present invention, the ink-jet head that prevents a nozzle from being blocked by a residual ink droplet formed on the nozzle can include a head body having the nozzle formed on one surface thereof and an actuator, which provides pressure to the inside of the head body. Here, a transfer groove is formed on one surface of the head body, in which the transfer groove is separated from the nozzle to provide a path through which the residual ink droplet moves. Thus, the inkjet head can prevent the nozzle from being blocked by a residual ink droplet formed on the nozzle by use of the transfer groove, which provides a path for a residual ink droplet formed on the nozzle to escape.

摘要： An ink-jet head is disclosed. The ink-jet head can include: a channel for holding ink, a nozzle connected with the channel, a pressurizing unit configured to apply pressure to the ink so as to eject the ink, a partition coupled to one side of the channel so as to block the channel, and an actuator configured to deform one side of the channel so as to open the channel. While pressure is applied to the ink, this pressure can be turned on and off, to provide pressure pulses for ejecting the ink. As such, with this arrangement, the ejection properties of the ink-jet head can be adjusted to various settings.
