At this time, the catheter that has not been utilized can be utilized for the steps of air suction or ink guiding. In addition, the catheter suction mechanism 1 of the continuous ink supply system of the present invention further has a catheter control valve 16 which is connected by a conduit to a cover/cover of the cover nozzle area (not shown) to cover the cover.

Flow out. Because the ink cartridge is inked, it will move back and forth inside the printer, so that the plate member 1621 and the valve body 1622 fixed to the carrier of the ink cartridge will also move back and forth along with the ink carrier. As shown, when the valve body 1622 is aligned with the guiding portion of the conduit connector 161, the guiding portion 1611 will be connected to the outlet end of the valve body 1622, so that the leading end of the guiding portion and the piston portion 16223 are mutually abutted. At this time, the piston valve 16223 is pushed to compress the elastic member 16222, causing the piston valve 16223 to retract in the sleeve 16224, and the piston 阙am is separated from the front end opening of the sleeve 16224, and the conduit joint 16i and the sleeve 16224 are closed.

In the main casing 10 of the catheter suction mechanism 1 of the continuous ink supply system of the present invention, a curved guiding portion 101 is provided to guide the elastic conduit 13, and a snap tube member 102 is further provided to position the elastic conduit 13 so that the elastic conduit 13 is arranged in parallel in the upper and lower directions and arranged in the left and right intervals. Therefore, when the turntable 15 is driven by the driving member 11 to rotate, each of the elastic conduits 13 is deformed by being pressed in different directions, but the mutual interference does not occur. Not only can the service life of the flexible conduit 13 be extended, but more importantly, since the components are simple and can be separately fixed during assembly, the installation characteristics are easy to assemble. In summary, the catheter suction mechanism of the continuous ink supply system provided in the present invention has a curved guiding portion and a snap tube member for positioning the elastic conduit, simplifying the steps and components of the group 13 1288078, and avoiding the elastic conduit. Mutual interference leads to the lack of ink guiding, and the conduit control valve is used to guide the waste ink collected on the cover of the capping nozzle area, and the pipe joint of the pipe control valve and the piston function of the valve member are matched with each other. The connection relationship between the connecting tube and the elastic conduit, and the interaction between the driving device and the components such as the rotating disc and the roller, so that the ink or air in the elastic conduit can be completely sucked out, not only avoiding the use of the absorbent cotton of the prior art. The design can achieve the purpose of pumping out the waste ink, and the use of the catheter control valve can completely avoid the contamination of the ink and cause pollution. In addition, the catheter suction mechanism of the continuous ink supply system of the present invention can be applied to the excess air in the suction ink and the ink used for the first time to perform the initial ink guiding work, which not only stabilizes the quality of printing, but also has the quality The advantages of many applications. More importantly, the catheter suction mechanism of the continuous ink supply system of the present invention has a small volume and a small volume, and the number of elastic conduits is not limited, the cost is low, and the application range is wide, which greatly improves the utilization of the conventional continuous ink supply system. The traditional pump to absorb the many defects caused by residual ink. Therefore, the present invention has indeed met the requirements of the invention patent, and the patent application is filed according to law. The above description is only the preferred embodiment of the present invention, and equivalent modifications or variations made by those skilled in the art to the spirit of the present invention should be included in the scope of the patent application contained in the present application. 14 1288078 [Simple description of the drawings] The first figure: a schematic diagram of a preferred embodiment of the catheter suction mechanism of the continuous ink supply system of the present invention.
