Title
(EN) INK-JET PRINTING DEVICE AND CLEANING METHOD THEREFOR
(FR) DISPOSITIF D'IMPRESSION À JET D'ENCRE ET SON PROCÉDÉ DE NETTOYAGE

Abstract
(EN)
An ink-jet printing device, comprising an ink storage container (101), a solvent storage container (102) and a printing head (110); at least one ink-jet hole (201) and at least one solvent-jet hole (202) respectively in pipe connection with a liquid outlet end of the ink storage container (101) and a liquid outlet end of the solvent storage container (102) are provided on the surface of the printing head (110), the solvent-jet hole (202) being provided at the edge of the ink-jet hole (201). The solvent sprayed through the solvent-jet hole (202) first wets the surface of the printing head (110), being easy to dissolve the ink precipitate adhered to the surface of the printing head (110), facilitating taking away of the ink precipitate during wiping, effectively cleaning the printing head (110), improving the printing efficiency and quality.
(FR)
Cette invention concerne un dispositif d'impression à jet d'encre, comprenant : un récipient de stockage d'encre (101), un récipient de stockage de solvant (102) et une tête d'impression (110). Au moins un trou de jet d'encre (201) et au moins un trou de jet de solvant (202) respectivement raccordés par tuyau avec une extrémité de sortie de liquide du récipient de stockage d'encre (101) et une extrémité de sortie de liquide du récipient de stockage de solvant (102) sont ménagés sur la surface de la tête d'impression (110), le trou de jet de solvant (202) étant disposé au bord du trou de jet d'encre (201). Le solvant projeté à travers le trou de jet de solvant (202) mouille d'abord la surface de la tête d'impression (110), de sorte à dissoudre facilement le précipité d'encre collé à la surface de la tête d'impression (110), ce qui facilite l'élimination du précipité d'encre pendant l'essuyage, de sorte à nettoyer efficacement la tête d'impression (110) et à améliorer le rendement et de la qualité d'impression.
(ZH)
一种喷墨打印设备,其包括墨水储液容器(101)、溶剂储液容器(102)以及打印头(110),打印头(110)表面上开设有分别与墨水储液容器(101)的出液端和溶剂储液容器(102)的出液端管道连接的至少一个墨水喷孔(201)和至少一个溶剂喷孔(202),溶剂喷孔(202)布置于墨水喷孔(201)的边缘。利用溶剂喷孔(202)喷出的溶剂先将打印头(110)表面进行润湿,容易将打印头(110)表面附着的墨水析出物溶解,有利于在擦拭时带走,使得打印头(110)有效清洁,提高打印效率和质量。
