Abstract: An inkjet nozzle device configured for venting a gas bubble during droplet ejection. The inkjet nozzle device includes: a firing chamber for containing ink, the firing chamber having a floor and a roof defining a nozzle aperture having a perimeter; and a heater element bonded to the floor of the firing chamber. The device is configured to satisfy the relationships A=swept volume/area of heater element=8 to 14 microns; and B=firing chamber volume/swept volume=2 to 6. The swept volume is defined as the volume of a shape defined by a projection from the perimeter of the nozzle aperture to the floor of the firing chamber, and includes a volume contained within the nozzle aperture.

Abstract: An inkjet nozzle device for symmetrically constrained bubble formation includes: a firing chamber having and an end wall, opposite sidewalls and a nozzle aperture defined in a roof thereof; a baffle plate positioned between the sidewalls of the firing chamber, such that a pair of firing chamber entrances are defined between side edges of the baffle plate and the sidewalls; and an elongate heating element bonded to a floor of the firing chamber, the heater element extending longitudinally between the baffle plate and the end wall. The baffle plate is wider than the heater element. Further, a centroid of the heater element coincides with a midpoint between the baffle plate and the end wall.

Abstract: An inkjet nozzle device includes a main chamber having a floor, a roof and a perimeter wall extending between the floor and the roof. The main chamber includes: a firing chamber having a nozzle aperture defined in the roof and an actuator for ejection of ink through the nozzle aperture; an antechamber for supplying ink to the firing chamber, the antechamber having a main chamber inlet defined in the floor; and a baffle structure partitioning the main chamber to define the firing chamber and the antechamber, the baffle structure extending between the floor and the roof. The firing chamber and the antechamber have a common plane of symmetry.
