Problems solved by technology

Such a problem is particularly noticeable when filling the functional liquid into the newly introduced functional droplet ejection head. In this case, sufficient suction force cannot be ensured before the functional liquid reaches the pump, so the time required for filling the functional liquid is long.
In addition, due to the decrease in the suction force, the discharge performance of the air bubbles from the channel in the head deteriorates, so the consumption of the functional liquid required for filling the functional liquid increases, and there is a problem that the expensive functional liquid is wasted.
Since the pump has rotating parts or reciprocating parts (movable parts), it is difficult to miniaturize and requires a wide space for installation

Embodiment 2

[0098] Next, Embodiment 2 of the present invention will be described. The basic structure of the droplet discharge device 1 of this embodiment is substantially the same as that of the above-mentioned first embodiment, but in the droplet discharge device 1 of the second embodiment, the point of difference is that: The working fluid is not compressed air from the air supply unit 5, but a functional fluid.

[0099] if refer to Figure 9 To illustrate, the supply port 102 of the injector 101 is connected to the functional liquid pump 201 composed of a high-pressure pump through the pressure regulating valve 202, and the discharge port 104 is connected to the recycling container 162 (storage pipe) through the connecting pipe 203 (discharging line). container). Also, in the present embodiment, the suction force of the ejector 101 is adjusted by controlling the pressure of the functional liquid delivered from the functional liquid pump 201 using the pressure adjustment valve 202 . ...

Abstract

An apparatus for sucking a function liquid droplet ejection head has an ejector and an arrangement for supplying the ejector with a working fluid. A cap is brought into close contact with a nozzle surface of the function liquid droplet ejection head, and the ejector is operated to thereby suck the nozzle surface through the cap by means of the working fluid.

Description

technical field [0001] The present invention relates to a suction method for a functional droplet discharge head, a suction device, a droplet discharge device, an electro-optic device, Electro-optical devices, electronic instruments. Background technique [0002] As a kind of droplet discharge device, in the conventionally known inkjet recording device, the head cap (cap) connected to the ink pump is in close contact with the printing head (functional droplet discharge head), The pump, through the head cap, sucks the ink from all the nozzles of the print head (for example, Japanese Patent Laid-Open No. 2000-127454 (refer to pages 2-3, pages 7-8, Figure 4 ). [0003] In the droplet discharge device, when cleaning the head to prevent clogging caused by drying, or when filling the functional liquid in the head flow path of the newly introduced functional droplet discharge head (initial filling), from All the nozzles of the functional droplet ejection head perform suction. ...
