  • Patent number: 11981134
    Abstract: A liquid discharge head includes a base plate, a cavity plate located on the base plate and including a cavity, and a piezoelectric actuator substrate located on the cavity plate. The cavity plate includes: a first groove located inside a contact region with the piezoelectric actuator substrate and configured to release an adhesive for bonding the cavity plate and the piezoelectric actuator substrate; and a second groove located in a manner to surround the contact region with the piezoelectric actuator substrate and configured to release the adhesive. The base plate includes a third groove configured to open the first groove to the atmosphere. The third groove is configured to communicate between the first groove and the outside through a first hole communicating with the first groove and a second hole located outside the contact region of the cavity plate and the piezoelectric actuator substrate.

  • Patent number: 11760091
    Abstract: A liquid discharge head includes a flow channel member including a first surface and a second surface opposite to the first surface, and a pressing unit on the first surface. The flow channel member includes a first discharge hole and a second discharge hole in the second surface, a first individual flow channel connected to the first discharge hole, a first pressurizing chamber on an upstream side of the first discharge hole in the first individual flow channel, a second individual flow channel connected to the second discharge hole, a second pressurizing chamber on an upstream side of the second discharge hole in the second individual flow channel, and a manifold commonly connected to an upstream side of first individual flow channel and an upstream side of the second individual flow channel. The first individual flow channel and the second individual flow channel have an overlapping portion in plan view.
