Embodiment Construction

[0021] Please refer to figure 1 It is a schematic cross-sectional view of a preferred embodiment of the ink cartridge 100 that automatically stops ink supply in the present invention. As shown in the figure, the ink cartridge 100 includes a reservoir 120 , an air valve 140 and a float 160 . Wherein, the storage 120 is used for containing ink. The reservoir has an air inlet channel 122 and an ink flow path 124 . The air valve 140 is disposed on the air inlet passage 122 for preventing ink from flowing out of the ink cartridge 100 through the air inlet passage 122 . The air valve 140 has an air valve body 142 and an air valve spring 144 . Wherein, the air valve body 142 is disposed in the intake passage 122 . The gas valve spring 144 is located between the gas valve body 142 and the reservoir 120 . When the air valve 140 is opened, the air valve spring 144 is compressed to generate an elastic restoring force to drive the air valve body 142 to close the intake passage 122 . ...

Abstract

The invention provides an ink box which can stop the ink supply automatically, comprising a memory, an air valve and a floating ball; wherein, the memory is used for receiving inks. The memory is also provided with at least an air inlet passage and an ink flowing path. The air valve is arranged in the air inlet passage and used for preventing the ink from flowing out to the ink box through the air inlet passage. The specific weight of the floating ball is less than that of the ink. When the water level of the ink in the memory is lower than a prearranged height, the floating ball closes the ink flowing path downwards. The ink box of the invention reduces the preparation cost as a sensor is saved; meanwhile, the ink box can avoid the problem that the ink jet head is damaged as single ink pump design is used.

Description

technical field [0001] The invention relates to an ink box, in particular to an ink box which can automatically stop ink supply. Background technique [0002] In the ink supply system of the inkjet printing machine, the ink required by the inkjet head to print the document is supplied by an ink tank. [0003] In the past, the common ink cartridge was disposable, with an inkjet head attached to it. Because the cost of the inkjet head is high, and the service life of the inkjet head is usually longer than the ink supply time of the ink cartridge. If the ink in the ink cartridge is used up, the ink cartridge must be discarded together with the inkjet head on it. The integrated design of the ink cartridge and the inkjet head will not only increase the cost of the ink cartridge, but also waste the cost if the inkjet head is discarded before its life is over. In order to solve this problem, there are many designs in which the inkjet head is separated from the ink cartridge to s...
