Embodiment Construction

[0035] see figure 1 , figure 1 is a cross-sectional view of the print head structure 10 of the first embodiment of the present invention. The printhead structure 10 of the first embodiment of the present invention is a fluid ejection structure with live valves. Such as figure 1 As shown, the bubble generator 14 includes two bubble generating devices, namely a first heater 14 a and a second heater 14 b, and the two heaters are adjacent to the nozzle hole 12 . Because of the difference in resistance between the two heaters 14a and 14b, when the two heaters 14a and 14b heat the fluid in the fluid chamber 16 (not shown), two air bubbles will be generated in turn. The first heater 14a generates first air bubbles (not shown), and the position of the first heater 14a is closer to the manifold 11 than the second heater 14b. The first air bubble isolates the manifold 11 and the nozzle hole 12 from each other, and the first air bubble can be regarded as a live valve to reduce the cr...

Abstract

A fluid injection head structure. The fluid injection head structure is formed on a substrate and has a manifold therein, bubble generators, a conductive trace, and at least two rows of chambers adjacent to the manifold in flow communication with the manifold. The conductive trace disposed on a top surface of the substrate and partially disposed between the two rows of the chambers above the manifold is used to drive the bubble generator.

Description

technical field [0001] The invention provides a fluid injection structure and a method for assembling the fluid injection structure, especially a fluid injection structure equipped with a power cord between two rows of bubble generators, and a method for assembling the fluid injection structure . Background technique [0002] Currently, fluid ejection devices are widely used in inkjet printers. Any improvement in the fluid ejection mechanism will result in higher quality inkjet printers and lower prices. Fluid injection devices can also be used in other fields, such as fuel injection systems, cell sorting, drug delivery systems, lithography, and microjet propulsion systems. [0003] Among the products on the market, only some can spray individual drops in the standard shape. One of the most successful designs uses heat to force a bubble to eject a droplet. This design is widely used because of its ease of manufacture and low cost. [0004] "Print head with field oxide a...
