Liquid ejection head, channel member thereof, manufacturing method, and liquid ejection device

Abstract

A liquid ejecting head includes a second flow-path-member comprising a second flow-path in communication with first and third flow-paths provided in first and second flow-path-members, the second flow-path-member stacked with the third flow-path-members in a stacking direction. A boundary between the first and second flow-path is tightly sealed by a first sealing-member. A boundary between the second and third flow-path is tightly sealed by a second sealing-member. The second flow-path-member includes a first substrate for positioning itself to the third flow-path-member in first and second directions intersecting with the stacking direction, and a second substrate for positioning itself to the third flow-path-member in the stacking direction. The first substrate is pressed against in the first and second directions by one of the first and second sealing-member. The second substrate is pressed against in the stacking direction by another one of the first and second sealing-member.

Description

[0001] This application claims the priority of Japanese Patent Application No. 2015-100440 filed on May 15, 2015. The entire disclosure of Japanese Patent Application No. 2015-100440 is incorporated herein by reference. Technical field [0002] The present invention relates to a liquid ejecting head that ejects liquid from a nozzle, a flow path member, a manufacturing method, and a liquid ejecting device, and more particularly to an inkjet recording head that ejects ink as a liquid, and a flow path member, a manufacturing method thereof, and Inkjet recording device. Background technique [0003] As a representative example of a liquid ejecting head that ejects liquid, there is an inkjet recording head that ejects ink. An inkjet recording head is proposed, which includes: a head body that ejects ink droplets from nozzles; and a flow path member that is fixed to the head body and supplies the head body from a liquid storage unit such as an ink cartridge that stores ink. Ink (for e...

Problems solved by technology

[0005] However, the first sealing member is pressed in the lamination direction to connect the third channel member to the second channel member, and the second sealing member is pressed in the first direction and the second direction to store the liquid. When the first flow path member such as a unit is connected to the second flow path member, if the dimensions of the components constituting the flow path member deviate, positional deviation occurs at the connection portion of the flow path and ink leakage occurs. The problem

[0006] In addition, in order to form a complicated flow channel in the second flow channel member, when the second flow channel member is formed by laminating a plurality of members, there may be dimensional deviation or Possibility of positional deviation at the connection part of the runner due to errors such as positional deviation during lamination
