Problems solved by technology

[0008] Moreover, such a problem exists not only in the inkjet recording head that ejects ink droplets, but also in the liquid ejection head that ejects other liquid droplets. In addition, it is not only in the case of embedding piping in the head cartridge by insert molding, but generally It also exists in the head where part of the piping buried in the head box is exposed

Embodiment approach 1

[0019] figure 1 is a plan view showing an example of the ink jet recording head according to Embodiment 1 of the present invention, figure 2 yes figure 1 The A-A line sectional view, image 3 yes figure 1 B-B line sectional view.

[0020] Such as Figure 1 ~ Figure 3 As shown, the head 10 is composed of a head main body 40 and a head case 50 holding the head main body 40 .

[0021] The head main body 40 is composed of a flow path forming substrate 12 joined to the vertically lower end surface of the head cartridge 50 and two piezoelectric element units 34 held in the The storage portion 51 provided in the head case 50 .

[0022] The flow path forming substrate 12 is made of a single crystal silicon substrate, and the pressure generating chambers 11 partitioned by a plurality of partition walls 17 are arranged side by side in the width direction (short side direction) at the surface layer portion on one surface side. Also, on one end side of each pressure generating cha...

Abstract

The invention relates to a liquid ejection head and a liquid ejecting apparatus. The liquid ejection head includes an ink jet recording head body that ejects ink and a head formed of a resin with a reinforcement member integrally molded therein and having a housing, wherein the head includes a groove in which a part of the reinforcement member is exposed to the bottom surface, and a liquid hold that holds ink and is disposed at the lower end of the groove in the vertical direction.

Description

[0001] The entire contents of Japanese Patent Application No. 2010-79885 filed on March 30, 2010 are hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to a liquid ejection head and a liquid ejection device that eject liquid, and more particularly, to an ink jet recording head and an ink jet recording device that eject ink as liquid. Background technique [0003] Conventionally, there are known liquid ejection heads that eject liquid droplets from nozzles by applying pressure to the liquid using a pressure generating unit such as a piezoelectric element or a heat generating element. As a typical example, an inkjet head that ejects ink droplets from nozzles can be cited. A recording head (hereinafter also referred to as a head). [0004] As such a head, for example, there is a structure in which a head main body is held in a head case formed of resin, wherein the head main body has: a nozzle plate through which a nozzle op...
