LIQUID EJECTING HEAD - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240326420 titled 'LIQUID EJECTING HEAD
Simplified Explanation: The liquid ejecting head described in the patent application consists of a piezoelectric element, a diaphragm, a pressure chamber substrate with a pressure chamber connected to a nozzle for liquid ejection, and a dummy pressure chamber that does not contribute to liquid ejection. The pressure chamber and dummy pressure chamber are recessed on the opposite surface of the diaphragm, with the dummy pressure chamber being shallower than the pressure chamber.
- The liquid ejecting head includes a piezoelectric element, diaphragm, pressure chamber, and dummy pressure chamber.
- The pressure chamber substrate has a pressure chamber connected to a nozzle for liquid ejection.
- A dummy pressure chamber is also present, but it does not contribute to liquid ejection.
- Both the pressure chamber and dummy pressure chamber are recessed on the opposite surface of the diaphragm.
- The dummy pressure chamber is shallower than the pressure chamber.

Original Abstract Submitted
a liquid ejecting head has a piezoelectric element, a diaphragm, and a pressure chamber substrate having a pressure chamber coupled to a nozzle and contributing to ejection of a liquid by applying pressure on the liquid through vibration of the diaphragm and a dummy pressure chamber not contributing to ejection of the liquid. each of the pressure chamber and the dummy pressure chamber opens on a surface opposite to a surface facing the diaphragm of the pressure chamber substrate, and is a recess having a depth in a direction toward the diaphragm along the lamination direction. furthermore, the pressure chamber and the dummy pressure chamber are arranged in an arrangement direction perpendicular to the lamination direction, and a first depth as the depth of the dummy pressure chamber is shallower than a second depth as the depth of the pressure chamber.
