Abstract: An ink cartridge test device, an ink cartridge component, and an ink cartridge component test method are provided. The ink cartridge component includes an ink cartridge package and ink cartridges accommodated in the ink cartridge package, and the ink cartridge package is provided with openings corresponding to the ink cartridges. The ink cartridge test device includes a device main body, a data transmission apparatus mounted on the device main body and in either or both of electrical connection and signal connection with the device main body, and test heads. The test heads are connected to the device main body and are in either or both of electrical connection and signal connection with the data transmission apparatus. The openings are configured to allow the test heads to be in either or both of electrical connection and signal connection with corresponding ink cartridges.

Abstract: The present disclosure provides an ink cartridge verification method, a system, a readable storage medium and a device. The method comprises: obtaining the total quantity of spray points of the ink cartridge; detecting the spray points of the ink cartridge to obtain the quantity of malfunctional spray points; when the ratio of the quantity of malfunctional spray points to the total quantity is less than or equal to a first preset ratio, determining that the ink cartridge passes verification. The malfunctional spray points are detected to obtain the ratio of the quantity of malfunctional spray points to the total quantity; when the ratio is low, it is determined that the ink cartridge passes verification, there will be no obvious influences on ink cartridge printing and the ink cartridge can be in normal use; and thus, the printing effect can be reflected after the ink cartridge is regenerated after being filled with ink.

Abstract: The present invention discloses a core-shell structure supported tungsten composite catalyst and a preparation method and use thereof. Most of the existing synthesis methods of the main ring of quinolone drugs have the defects of many synthesis steps, cumbersome operation, large amount of three wastes, higher costs and the like. The present invention prepares a magnetic separable core-shell supported tungsten composite catalyst, WO3/SiO2/Fe3O4, by preparing Fe3O4 colloid and SiO2/Fe3O4 composite nano-particles. This magnetic separable core-shell supported tungsten composite catalyst, WO3/SiO2/Fe3O4, is used to catalyze and synthesize quinolone compounds. The present invention provides an efficient preparation method of quinolone compounds using a catalyst which can be recovered by magnetic separation and recycled.
