Embodiment Construction

[0043] figure 1 A specific example of the droplet ejection head 100 installed in the non-contact writing apparatus 1 is shown. However, the present invention is not limited to writing devices, and those skilled in the art will appreciate that this is only one possible embodiment, which can be equally effectively applied to palm printers, desktop printers, correction devices, painting devices or without Other equipment that releases liquid onto the support by physical contact between the equipment and the support.

[0044] The writing device has a generally tubular member extending from a front end 11 to a rear end 12 to form a pen shape. This tubular member has an inner side wall 13 defining a hollow interior space and an outer side wall 14 designed to be held in the user's hand.

[0045] The inner hollow space of the writing device 1 includes: a liquid reservoir 15 which is installed in a detachable manner so that end users can easily replace it; and contains a liquid 16 . ...

Abstract

A liquid droplet ejecting head (100) designed to be mounted in a liquid ejecting instrument (1) . The liquid droplet ejecting head contains actuating chambers (105). Each actuating chamber has at least one inlet (107) to be in connection with a liquid reservoir (15) for providing liquid (16) to the actuating chamber (105), actuating means (120) for creating a pulse wave in the liquid when activated by energy received from a control device (20), and outlet portions (108) in connection with ejection nozzles (99). The nozzles (99) are arranged such that the ejected droplets combine at a point situated a certain distance away from the head (100).

Description

technical field [0001] The present invention relates to a droplet ejection head, and a droplet ejection device including the droplet ejection head. The present invention also relates to a method of ejecting liquid droplets from such a liquid drop ejection head. [0002] In particular, the present invention relates to a droplet ejection head designed to be installed in a droplet ejection device. The droplet ejection head includes: a plurality of nozzles through which droplets are ejected from the droplet ejection head; and a plurality of actuation boxes, each actuation box having: at least one water inlet, the water inlet being fluidly connected to a reservoir for supplying liquid to said actuating tank; at least one actuating device adapted to be actuated by energy received from the control assembly when the at least one actuating device is actuated A pulse wave is generated in the liquid; and at least one water outlet part is liquid-connected to at least one nozzle among th...
