摘要:
A porous back-shooting inkjet print head module is disclosed. The ink permeates through the porous ink supply layer into an ink chamber in contact with the outside by an injection hole, and the porous ink supply layer prevents the ink from flowing back. Therefore, the ink chamber is sealed very well and more pressure could be generated. The invention can thus be used for inks with high viscosities. It does not need a precision alignment process as in the prior art. This does not only increase the efficiency and yield of production, but also reduces the cost.

A back-shooting inkjet print head. The inkjet print head comprises: a first substrate having a plurality of thermal resistors formed on a back surface thereof, and a plurality of orifices formed through the first substrate and respectively located proximate to the resistors; an isolation layer having a plurality of ink channels formed therein, wherein the isolation layer is arranged onto the back surface of the first substrate such that the region of each ink channel covers that of one of the resistors and one of the orifices; and a second substrate having an ink supply window, wherein the second substrate is arranged on the isolation layer covering the ink channels, such that the ink supply window, connected to the ink channels, is located at one side of the resistors while the orifices of the first substrate are located at the other side of the resistors and face the second substrate.
