摘要： An inkjet printing device allows separation of ink solvent liquefied in an exhaust passage from exhaust gas, and prevents the separated exhaust gas from contaminating the inside of the print head. When ink fed from a container is jetted from a printing nozzle, ink that has not been used for the printing is drawn by a gutter along with air and collected in the container. Air mixed with the ink solvent and collected is discharged as exhaust gas into an exhaust passage from the container. The ink solvent that has been liquefied in the exhaust passage is separated from the gas by retaining the liquid using capillary action in a gas-liquid separator, and the separated liquefied ink solvent is collected. The trace amount of the ink solvent leaking on the exhaust side of the gas-liquid separator is prevented from dripping into the print head by a drip prevention unit.

A gap is formed around the gas-liquid outlet pipe in the chamber for separating the mixture into liquid and gas using the surface tension and suction force. The gas-liquid separator is installed in the inkjet recording apparatus, especially in the print head. The print head is filled with the solvent gas so as to be suctioned from the gutter to reduce the solvent consumption.

摘要： An ink that is unused for printing when a supply ink from an ink container is ejected from a nozzle, and printing is conducted on an object to be printed is sucked by a gutter together with an air, and the ink and air are recovered into the ink container. In this situation, the air mixed with an ink solvent and recovered is discharged as an exhaust gas from the ink container by an exhaust path, and at this time, the ink mist is removed from the exhaust gas in which a liquefaction ink solvent liquefied within the exhaust path and the ink mist are mixed together by an ink mist mixture unit. Thereafter, the liquid is held by the aid of a capillary action, and separated from the gas in a gas-liquid separator to recover the separated liquefaction ink solvent.
