  • Handheld and/or mountable fluid-ejection device having tip-extension assembly and/or tubings
    Patent number: 8211383
    Abstract: A fluid-ejection device includes a handheld and/or mountable enclosure, a removable tip having a fluid-ejection mechanism, a first fitting extending from the enclosure and receptive to placement of the removable tip thereon, and a controller situated within the enclosure to cause the removable tip to eject the fluid. The fluid-ejection device may also include tip-extension assembly having an electrical cable connecting to the controller and having a second fitting receptive to placement of the removable tip thereon. The electrical cable permits the removable tip to be located substantially independently of the enclosure. The fluid-ejection device may further include tubings fluidically couplable with the removable tip through at least one of the first and second fittings to provide fluid to the removable tip and to regulate backpressure of the fluid within the removable tip.
