Liquid jet head with simplified waveform configuration for jetting liquid
A recently granted patent (Publication Number: US11845272B2) discloses a liquid jet head designed to jet liquid with precision. The invention includes a jet section for liquid ejection, a drive device applying a predetermined drive waveform to the jet section, and a waveform setting section that converts simplified waveform configuration information into regular waveform configuration information. This conversion involves setting power supply potential values based on reference potential values along a time axis, ensuring accurate liquid jetting.
Furthermore, the liquid jet head features a unique configuration where power supply potential values are set in accordance with allowable consumption current values in power supply lines. The regular waveform configuration information generated by the waveform setting section ensures equal setting frequencies for power supply potential values, promoting efficient liquid jetting. Additionally, the invention includes error notification mechanisms for inappropriate waveform configurations and utilizes a compact data format for simplified waveform configuration information. The patent also covers a liquid jet recording device incorporating this innovative liquid jet head technology, enhancing liquid jetting accuracy and efficiency in recording applications.
