Description
上記の目的を達成するために本発明は、以下の構成を採用している。
本発明の液体噴射ヘッドは、液体を噴射するノズルがノズル形成面に形成され、液体噴射装置に走査移動可能に搭載される液体噴射ヘッドであって、前記ノズル形成面の前記ノズルを含む領域を囲むように該ノズル形成面より突出する壁部が設けられ、前記壁部により囲まれる前記領域の前記走査移動方向の幅をＢ、該壁部の高さをＨとしたときに、Ｂ／Ｈ ≦ １．０の式を満足することを特徴とする。
本発明の液体噴射ヘッドは、液体を噴射するノズルがノズル形成面に形成され、走査移動して前記ノズルから前記液体を噴射する液体噴射ヘッドであって、前記ノズル形成面から突出して前記走査移動に伴う強制対流で生じる気体の流れを規制する規制空間を、前記ノズルと対向する領域に形成する壁部が設けられ、前記規制空間は、前記走査移動方向の幅及び高さが前記強制対流で該規制空間に生じる気体の流れに関して、前記ノズル形成面と沿う方向の気体の流れを非形成とする大きさで形成されることを特徴とするものである。
In order to achieve the above object, the present invention employs the following configuration.
The liquid ejecting head of the present invention is a liquid ejecting head in which a nozzle for ejecting liquid is formed on a nozzle forming surface and is mounted on the liquid ejecting apparatus so as to be capable of scanning movement, and includes a region including the nozzle on the nozzle forming surface. A wall portion protruding from the nozzle forming surface is provided so as to surround, and when the width in the scanning movement direction of the region surrounded by the wall portion is B and the height of the wall portion is H, B / H ≦ 1.0 is satisfied.
The liquid ejecting head of the present invention is a liquid ejecting head in which a nozzle for ejecting liquid is formed on a nozzle forming surface, and scans and moves to eject the liquid from the nozzle. A wall for forming a restriction space for restricting a gas flow generated by forced convection associated with the nozzle in a region facing the nozzle, and the restriction space has a width and height in the scanning movement direction in the forced convection. The gas flow generated in the restriction space is formed in such a size that the gas flow in the direction along the nozzle forming surface is not formed.
上記の液体噴射ヘッドにおいては、前記走査移動方向の幅をＢ、高さをＨとしたときに、Ｂ／Ｈ ≦ １．０の式を満足する構成や、さらに好ましくは、Ｂ／Ｈ ≦ ０．５の式を満足する構成を好適に採用できる。 In the above liquid jet head, width B of the scanning movement direction, the height when the H, structure and satisfying an expression of B / H ≦ 1.0, more preferably, B / H ≦ 0 A structure satisfying the expression .5 can be preferably used.
そして、上記の液体噴射ヘッドにおいては、前記壁部により囲まれる前記領域が前記走査移動方向と交差する方向に配列された複数の前記ノズルに跨って形成される構成を好適に採用できる。
これにより、本発明では、前記走査移動方向と交差する方向に配列されたノズルに対しては、凹条として一括的に規制空間を形成することが可能になり、ヘッド製造に要する作業を効率化できる。
In the liquid ejecting head, a configuration in which the region surrounded by the wall portion is formed across a plurality of the nozzles arranged in a direction intersecting the scanning movement direction can be suitably employed.
As a result, according to the present invention, it is possible to form a restriction space collectively as a concave line for the nozzles arranged in the direction intersecting the scanning movement direction, thereby improving the efficiency of the work required for head manufacture. it can.
また、上記の液体噴射ヘッドにおいては、前記ノズルが複数形成され、前記壁部により囲まれる前記領域が、前記複数のノズルのそれぞれに形成される構成も好適に採用できる。
これにより、本発明では、走査移動方向とは異なる方向からの気体の流れで液体に含まれる溶媒のノズルからの蒸発を最小限に抑制することが可能になる。
In the above liquid ejecting head, a configuration in which a plurality of the nozzles are formed and the region surrounded by the wall portion is formed in each of the plurality of nozzles can also be suitably employed.
As a result, in the present invention, it is possible to minimize evaporation of the solvent contained in the liquid from the nozzle by the gas flow from a direction different from the scanning movement direction.
