Problems solved by technology

[0007] Also, in the printer devices described in Patent Documents 1 and 2, the agitation of the ink and the degassing of the ink are not continuously performed at the same time only by simply agitating the ink, and therefore, the gas dissolved in the ink cannot be removed.
Therefore, when air bubbles are generated in the ink, the air bubbles clog the ink flow path or the nozzles of the head, and therefore, there is a problem of causing ink ejection failure or printing failure.

Embodiment Construction

[0040]Hereinafter, an embodiment in which the present invention is embodied as a printer device will be described with reference to the drawings.

[0041] figure 1 Indicates the configuration of the printer device.

[0042] Such as figure 1 As shown, a printer device 1 as a liquid ejecting device has: an ink cartridge 2 (hereinafter referred to as a cartridge) as a liquid storage portion that stores ink 1 (hereinafter, referred to as ink without a symbol) as a liquid; The head 3 as the liquid ejection section; the ink flow path 4 as the liquid flow path that communicates the cartridge 2 and the head 3; the pump P as the liquid level changing mechanism 65; the control mechanism 5; Stirring and degassing device 50 at halfway position. In the ink flow path 4, the part between the stirring and degassing device 50 and the cartridge 2 is formed as the cartridge-side ink flow path 4a, and the part between the stirring and degassing device 50 and the head 3 is formed as the head-si...

Abstract

The present invention relates to a liquid ejecting apparatus capable of concurrently stirring and deaerating a liquid in a continuous manner. A printer (1) has a liquid container which contains a liquid; a liquid ejecting unit which ejects the liquid supplied from the liquid container; a cavitation generator which generates cavitation in the liquid; and a gas discharging port which discharges a gas separated from the liquid by the cavitation.

Description

technical field [0001] The present invention relates to a liquid spraying device capable of continuously stirring a liquid and degassing the liquid simultaneously. Background technique [0002] In general, inks using color components that are insoluble in solvents or color components that are hardly soluble in solvents are known as inks used in printers that are one type of liquid ejection devices. For example, pigment-based inks are in a state in which fine particles of pigments as color components are dispersed in a solvent such as water or petroleum-based solvents, so the pigments tend to precipitate. Specifically, white pigments have a specific gravity of about 4, and metallic pigments have a specific gravity of about 2 to 3, whereas solvents have a specific gravity of less than 1, and the difference in specific gravity between the pigment and the solvent is 1 or more, so the pigments tend to precipitate. [0003] In addition, when an insoluble or poorly soluble dye is ...
