As shown in fig. 7, the cover 22 is provided with an air vent 221 communicating with the accommodating cavity, and the air vent 221 is used for communicating with the accommodating cavity to balance the air pressure between the accommodating cavity and the external environment, so that the ink can flow out smoothly. Simultaneously, through deriving the air that holds the intracavity, avoid holding the ink in chamber and dry because of the air evaporation. Alternatively, the air holes 221 may be circular or square as long as they are communicated. Preferably, the cover 22 is further provided with an ink injection hole 222, and ink is injected into the accommodating cavity through the ink injection hole 222, so that the operation is simple and convenient. The number of the ink injection holes 222 and the air guide holes 221 is related to the type of the ink cartridge. In order to prevent the ink inside the accommodating cavity from evaporating and drying due to the entrance of the external air through the air guide hole 221 and to prevent the ink from flowing out through the air guide hole 221 and the ink injection hole 222, the ink bag 2 further includes a surface coating, an air guide groove 223 is formed in the cover body 22, one end of the air guide groove 223 is communicated with the air guide hole 221, the surface coating covers the air guide groove 223, the air guide hole 221 and the ink injection hole 222, and an opening communicated with the outside is formed in the other end of the air guide groove 223. Specifically, the surface coating may be an aluminum plate or a plastic film. Preferably, the surface coating is made of transparent PVC material, and the condition of the ink in the accommodating chamber can be observed from the air vent 221. When air exists in the accommodating cavity, the air is located above the inside of the ink bag shell 2 because the density of the air is smaller than that of the ink, flows into the air guide hole 221, enters one end of the air guide groove 223, circulates along the air guide groove 223, flows to the other end of the air guide groove 223, and finally flows out of the opening to be merged into the outside air. Wherein, because the surface coating covers on air guide hole 221, can't utilize air guide hole 221 balance to hold the atmospheric pressure between chamber and the external environment, lead to holding chamber and outside to have pressure differential, be difficult to annotate the china ink, consequently, the other end of air guide groove 223 sets up the opening, and opening and outside air intercommunication for hold the atmospheric pressure between chamber and the external environment, make and annotate the china ink success. The air guide groove 223 may be a straight pipe section for guiding out the air inside the accommodating cavity. Preferably, the air guide groove 223 is curved on the cover 22, and the air guide groove 223 forms a zigzag curve to prevent the ink from flowing out along the air guide hole 221 and the air guide groove 223.

Referring to fig. 8, in order to protect the ink bag 2 and prevent ink in the ink bag 2 from leaking from the ink outlet 211, the ink cartridge device further includes an ink bag protection cover 200, and when the ink bag 2 is not needed, the ink bag 2 is placed in the ink bag protection cover 200.

Based on the above embodiment, the present application also discloses another specific embodiment. The present embodiment differs from the above-described embodiments in that the elastic member 3 is provided at the bottom of the ink bag body 21. If ribs or other protrusions are present inside the print head housing 1, they are not or relatively difficult to handle. There will be some difficulty in disposing the elastic member 3 at the bottom of the mounting chamber, and it will be more convenient to dispose the elastic member 3 at the bottom of the ink bag.

The above description is only for the preferred embodiment of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present application should be covered within the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
