Embodiment Construction

[0013] Embodiments of the present invention will now be described in conjunction with the accompanying drawings.

[0014] figure 1 It is a schematic diagram of the first preferred embodiment of the ink suction tube of the present invention. Such as figure 1 As shown, the patent of the present invention is an ink bottle with an ink suction tube of a limit device, which includes a bottle body 1 and an ink suction tube 2, and one end of the ink suction tube 2 is provided with a limit mechanism 2-1.

[0015] Such as figure 1 Shown, ink suction tube 2 upper limit mechanism 2-1 is made of several apertures. Like this, when the ink level drops to be flush with the small hole that is positioned at the uppermost end, the pressure inside and outside the ink suction tube reaches balance, and the ink suction tube 2 can no longer suck ink, thereby ensuring that the ink will not be sucked dry.

[0016] figure 2 and image 3 It is a schematic diagram of the third preferred embodiment ...

Abstract

The invention discloses an ink cartridge equipped with an ink-sucking pipe containing a stopper device. The ink cartridge comprises a cartridge body and an ink-sucking pipe. One end, extending into the corresponding ink cartridge, of the ink-sucking pipe is provided with a stopper device. By means of the stopper device, the ink-sucking pipe may suck the ink but cannot extend to the bottoms of the ink cartridge. Therefore, the ink in the ink cartridge cannot be completely sucked such that a printing nozzle device is protected against damage.

Description

technical field [0001] The invention relates to a printing device, in particular to an ink bottle for an inkjet printer. Background technique [0002] In the prior art, inkjet printers or digital inkjet printers use an external ink supply system. Usually, an external ink supply system includes a container for holding ink and an ink bottle for delivering ink. One end of the ink suction tube is connected to the nozzle of the printer. When the ink is placed for a long time, it is easy to produce sediment or aggregate into fine particles. These sediments or fine particles generated in the ink are easy to cause blockage or damage to the nozzle of the inkjet printer or inkjet printer, and also affect the nozzle of the inkjet printer. Printed image quality will be adversely affected. The ink suction tubes in these ink supply devices in the prior art are all easily inserted into the bottom of the ink bottle, causing the ink to be sucked dry of the sediment in the bottle, and furthe...
