Technical Field

The invention discloses an annular coating nozzle, relates to a spraying device, and particularly relates to a coating nozzle for spraying coating on the surface of an object.

Background

The present invention relates to a method for manufacturing a liquid ejecting head, and a liquid ejecting apparatus, and more particularly to a method for manufacturing an ink type recording head that ejects ink as a liquid, and an ink jet type recording apparatus. In an ink jet recording head as a typical example of a liquid ejecting head, ink from an ink cartridge storing ink is generally supplied to a nozzle opening through an ink supply needle inserted into the ink cartridge and a flow path, and when a piezoelectric element is driven, the ink is ejected from the nozzle opening. The invention provides a method for manufacturing a liquid ejecting head, and a liquid ejecting apparatus, which can prevent a piezoelectric body from cracking due to a longitudinal tensile force applied to the piezoelectric element from a substrate. The flow channel forming substrate is provided with a piezoelectric element having a width in a reference direction longer than a width in a perpendicular direction. The nozzle plate is bonded to the surface of the flow path forming substrate opposite to the piezoelectric element at a temperature lower than the normal temperature. As the nozzle plate, a nozzle plate is used in which the 1 st thermal expansion coefficient in the 1 st direction of the bonding surface to which the flow path forming substrate is bonded is smaller than the 2 nd thermal expansion coefficient in the 2 nd direction, and the 1 st thermal expansion coefficient is smaller than the thermal expansion coefficient of the flow path forming substrate. The 1 st direction of the nozzle plate is joined in line with the reference direction.

The technical scheme of the patent is only suitable for printing equipment and the printing industry, and has certain speciality and limitation. Is not suitable for paint spraying
