Another purpose of the present utility model, be to provide the technical scheme that to carry out continuous ink feeding to existing ink-jet printer, promptly under the prerequisite that box storage capacity and shape are determined, provide and to make machine operation under lower live load state, thereby guarantee print speed and printing precision, simultaneously, can continue the continuous ink feeding device of ink supply in a large number.

For achieving the above object, the technical solution adopted in the utility model is to fix a black chamber removably at printhead ink supply pin place, the China ink chamber is a housing that has small volume of ink liquid, the ink supply port that this housing has a corresponding ink supply pin with printhead to cooperate, also have the storage ink reservoir of a total board of horizontal level a little less than ink supply port, the storage ink reservoir can be fixed on the sidewall of print enclosure, also can be shelved on the other workbench of printer, and be communicated with black chamber by flexible pipe.

Like this, the China ink chamber can be designed very for a short time, the ink supply pin of its ink supply port and printhead can adopt the known mode that is connected and fixed, as screw thread spin, buckle snapping etc., promptly follow and print cephalomotor very light in weight, simultaneously, the volume of printhead also can design very for a short time, makes that reducing power of motor, raising print speed and scaled down printer size becomes possibility.A large amount of ink supply in the time of guaranteeing again simultaneously to grow relatively, generally speaking, the China ink amount that needs only in the storage ink reservoir can be learnt intuitively, as adopt transparent bottle, liquid level to show signal etc., just can be at any time in the storage ink reservoir, add black liquid in print job or during inoperative, thereby realize to the printhead continuous ink feeding.Simultaneously, the ink feeding system that provides according to the utility model can use in phase projected life of a plurality of printheads repeatedly, has solved discarded many problems that contain the print cartridge of residual China ink of print head design lifetime domestic demand in the prior art, helps environmental protection.

For adaptive with existing printer, can be by an ink supply frame of size design in Write head container storehouse, it is black chamber that its structure can be designed to an end, the outer wall of China ink chamber one side has the button bit that cooperates with printhead, the outer wall of opposite side connects a crossbearer, and the other end of crossbearer has perpendicular stand of putting, and a reference column is arranged at the bottom of crossbearer, also have a cantilever-shaped resilient handle, there is one second button bit at the middle part of handle.Like this, press down after hand-held stand and resilient handle are gone into printhead with the button bit oblique cutting of black cavity outer wall, can make second button bit on reference column and the resilient handle in place, the ink supply frame just is securely fixed in the printhead of existing printer.Obviously, this ink supply frame that adapts to existing printer can design weight much smaller than the weight of existing print cartridge, this can realize purpose of design of the present utility model equally.

Be to guarantee the stability of ink supply, also can be in black chamber the placing porous Sponge, produce foam in the China ink chamber when preventing the printhead high-speed motion, place an ink inducing element at the ink supply port place, can improve the stability of ink supply more.

The flexible pipe that connects storage ink reservoir and black chamber is communicated with the sealing of black chamber, prevents that air from entering printhead.For some color printer, be divided into a black box storehouse and a colour box storehouse in the printhead, configurable two the ink supply framves of this class printer, a black chamber is set on the black ink supply frame, and by flexible pipe connection black storage ink reservoir, a plurality of black chambeies are set on another ink supply frame, and with independent flexible pipe and corresponding storage ink reservoir connection, the quantity in black chamber and color are corresponding with the quantity and the color of printhead ink supply pin demand on the ink supply frame respectively in each black chamber.
