LIQUID EJECTION HEAD AND MANUFACTURING METHOD OF LIQUID EJECTION HEAD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18485183 titled 'LIQUID EJECTION HEAD AND MANUFACTURING METHOD OF LIQUID EJECTION HEAD

Simplified Explanation

The abstract describes a liquid ejection head that includes ejection orifices, common liquid chambers, common flow passages, and pitch conversion flow passages. The pitch conversion flow passages connect the common flow passages and liquid chambers to each other and are formed with resin. The pitch conversion flow passages have a repeating pattern in which a group of one or more pitch conversion flow passages is repeatedly arranged. Adjoining pitch conversion flow passages have a specific relationship to each other.

  • The liquid ejection head includes ejection orifices for ejecting liquid.
  • It has common liquid chambers connected to the ejection orifices.
  • There are common flow passages that connect the liquid chambers and ejection orifices.
  • Pitch conversion flow passages connect the common flow passages and liquid chambers.
  • The pitch conversion flow passages have a periphery formed with resin.
  • The pitch conversion flow passages have a repeating pattern.
  • Adjoining pitch conversion flow passages have a specific relationship to each other.

Potential applications of this technology:

  • Inkjet printers
  • 3D printers
  • Industrial printing systems

Problems solved by this technology:

  • Efficient and precise liquid ejection
  • Improved flow control
  • Minimization of clogging or blockages

Benefits of this technology:

  • Enhanced printing quality
  • Increased printing speed
  • Reduced maintenance requirements


Original Abstract Submitted

A liquid ejection head includes ejection orifices for ejecting liquid, common liquid chambers connected to the ejection orifices, common flow passages, and pitch conversion flow passages that connects the common flow passages and liquid chambers to each other. The pitch conversion flow passages includes a periphery formed with resin. In a case where a number of pitch conversion flow passages in a group is minimum on a condition that one or more of the pitch conversion flow passages are respectively included in the group, the pitch conversion flow passages have a repeating pattern in which the group is repeatedly arranged. At least one of two pitch conversion flow passages adjoining an m-th pitch conversion flow passage (m is all integers from 1 to n−2, where n is an integer of 3 or more) is one of first to (m+1)-th pitch conversion flow passages.
