Embodiment Construction

[0017] see Figure 1 to Figure 5 An ink cartridge 100 includes an ink storage chamber 20 and an ink guide member 60 fixedly connected with the ink storage chamber 20 . The ink guide member 60 is used to guide the ink in the ink bottle 80 into the ink storage chamber 20 .

[0018] The ink storage chamber 20 includes a bottom plate 22 and a first side wall 24 and a second side wall 26 fixed on the bottom plate 22 . The second side wall 26 is connected to both ends of the first side wall 24 , and the bottom plate 22 , the first side wall 24 and the second side wall 26 together form an ink storage chamber 28 . An ink outlet tube 30 communicated with the ink storage chamber 28 is fixed on the outer side of the first side wall 24 . The ink guide member 60 includes a fixing seat 62 fixed on the bottom plate 22 and protruding from the outer side of the first side wall 24 , and a cannula 64 fixed on the fixing seat 62 . The cannula 64 is used for inserting the ink bottle 80 . An in...

Abstract

An ink cartridge includes an ink storage chamber, the ink storage chamber includes a bottom plate, a first side wall and a second side wall fixed on the bottom plate, a wall fixed on the bottom plate and protruding from the outside of the first side wall A fixing base and an intubation tube fixed on the fixing base. The second side wall connects the two ends of the first side wall and the bottom plate, the first side wall and the second side wall together form an ink storage chamber, and the insertion tube is used for plugging An ink bottle, the side of the insertion tube forms an ink inlet and a vent, the ink inlet is located above the vent and is at least a preset distance away from the end of the insertion tube away from the fixing seat, and the fixing seat An ink outlet and an air guide port are formed on the top, the ink inlet communicates with the ink outlet, the ink outlet communicates with the ink storage chamber, and the air guide communicates with the air vent and the external atmospheric pressure. The air guide port is closer to the intubation tube than the ink outlet.

Description

technical field [0001] The present invention relates to an ink cartridge. Background technique [0002] The ink filling device includes an ink bottle and an ink cartridge. Existing ink cartridges generally have an ink filling cannula, the top of which is provided with an air channel and an ink channel, the ink bottle is inserted upside down on the ink filling cannula of the ink cartridge, and the ink in the ink bottle acts on the airway and the gravity of the ink itself. It is automatically injected into the ink cartridge. Although this type of ink filling device can easily inject ink into the cartridge, when an air blockage occurs in the ink passage, the ink filling will stop before completion or the ink filling cannot be automatically injected into the ink cartridge when the ink bottle is replaced. SUMMARY OF THE INVENTION [0003] In view of this, it is necessary to provide an ink cartridge that avoids gas locks. [0004] An ink cartridge includes an ink storage cham...
