Liquid discharging method, a liquid discharge head, and a liquid discharger apparatus

A liquid discharge head comprising:

• a discharge opening for discharging liquid;
• a liquid flow path provided with a bubble generating area for creating a bubble, and communicated with said discharge opening;
• a substrate provided with a heat generating element arranged in said bubble generating area for generating heat for creating the bubble;
• and
• a movable member provided with a free end in said liquid flow path to face said heat generating element;
• wherein liquid is discharged from said discharge opening by displacing said movable member by pressure exerted by creation of the bubble, and
• wherein said heat generating element and said movable member are arranged to be in two sets to face each other at least partly so that one of said movable members can come closer to the other of said movable members.

A liquid discharge head comprising:

• a discharge opening for discharging liquid;
• a liquid flow path provided with a bubble generating area for creating a bubble, and communicated with said discharge opening;
• a substrate provided with a heat generating element arranged in the bubble generating area for generating heat for creating the bubble;
• and
• a movable member provided with a free end on said discharge opening side, and arranged in said liquid flow path to face said heat generating element;
• wherein the liquid is discharged from said discharge opening when said movable member is displaced by pressure exerted by creation of the bubble, and
• wherein said heat generating element and said movable member are arranged to be in two sets to allow said movable members to face each other at least partly through said liquid flow path.

A liquid discharge head for a liquid discharge apparatus comprising:

• a liquid flow path communicated with a discharge opening for discharging liquid;
• a bubble generating liquid flow path provided with a bubble generating area for creating a bubble in the liquid;
• a heat generating element arranged in said bubble generating area to generate heat for creating the bubble;
• and
• a movable separation film for separating said liquid flow path and said bubble generating liquid flow path substantially from each other at all times,
• wherein the liquid is discharged from said discharge opening by displacing said movable separation film by pressure exerted by creation of the bubble, and
• wherein said liquid discharge head is provided with said heat generating element, said bubble generating liquid flow path, and said movable separation film arranged to be in two sets to allow at least parts of a movable range of said movable separation film to face each other with said liquid flow path therebetween.
