Problems solved by technology

However, ultrasonic welding often causes burnt particles and other matter to enter the printhead (possibly clogging ink conduits and / or nozzle holes), leading to premature printhead failure
Adhesives have the problem of impractically too long cure times

Abstract

The invention relates to an inkjet print head, which comprises a main body provided with an inner part and an outer part, a plurality of ink feed tanks, at least two ink guide tubes, and at least two ink guide tube plug parts, wherein, the inner part of the main body is provided with a plurality of ink chambers, and each ink chamber is provided with an ink discharge opening; each ink feed tank is used for receiving the ink discharged from one ink discharge opening; each ink guide tube is positioned between one ink discharge opening and one ink feed tank, and is provided with an opening arranged outside the main body; each ink guide tube plug part is covered at one opening outside the main body, and at least two ink guide tube plug parts are connected with together via a connecting plate made of flexible material and configured with an angle or a plurality of angles.

Description

[0001] This application is a divisional application of Chinese Patent Application No. 200480014802.2 (application date: April 13, 2004; title of invention: ink conduit plug for inkjet print head and its laser welding method). technical field [0002] The present invention relates to ink jet printheads, and more particularly to plugs for sealing ink conduits between ink chambers and heater lamellae in ink jet printheads, and more particularly to laser welding such ink conduit plugs to ink jet printing head body. Background technique [0003] Ink jet printing technology is well known and, generally speaking, images are produced by instantaneously firing droplets of ink from an ink jet print head impacting a print medium, such as paper, at a desired location. The printhead is supported by a device, such as a movable print carriage in an inkjet printer, and reciprocates relative to the advancing print medium to fire droplets of ink in time as directed by a microprocessor or othe...
