Abstract
A nozzle head includes a plate portion arranged in a plate shape, a droplet discharging nozzle portion located in the plate portion, the droplet discharging nozzle portion including a plurality of droplet discharging nozzles ejecting droplets by an electrostatic discharging method, and a pseudo-nozzle portion located around the droplet discharging nozzle portion in the plate portion and including a plurality of pseudo-nozzles. In the nozzle head described above, the plurality of droplet discharging nozzles may be arranged in line in a first direction, and the pseudo-nozzle portion may be arranged on both sides of the droplet discharging nozzle portion.
Claims9
A nozzle head comprising:
- a plate portion having a through hole;
- a droplet discharging nozzle portion located corresponding to the through hole in the plate portion, the droplet discharging nozzle portion including a plurality of droplet discharging nozzles discharging droplets by an electrostatic discharging method;
- and
- a pseudo-nozzle portion located around the droplet discharging nozzle portion in the plate portion and including a plurality of pseudo-nozzles whose tips are blocked,
- wherein each of the droplet discharging nozzle and the pseudo-nozzle has a tapered shape,
- wherein an inner diameter of an opening at a tip end of each droplet discharging nozzle is 50 μm or less, and
- wherein a first height from the plate portion to the tip of the pseudo-nozzle is lower than a second height from the plate portion to the tip of the droplet discharging nozzle.
