Along the height direction 03 of the ink cartridge holder 10, the upper side of the ink cartridge holder 10 is provided with a push rod 12 for unsealing the air inlet of the ink cartridge.

[0029] like Figures 1 to 6 As shown, the installation direction 01 of the ink cartridge is the length direction of the ink cartridge, the height direction 03 of the ink cartridge holder 10 is the height direction of the ink cartridge, and the width direction 02 of the ink cartridge holder 10 is the width direction of the ink cartridge.

[0030] See also Figures 2 to 4 The ink cartridge 100 comprises a shell 110 , on which an ink storage chamber 111 for storing ink is disposed. Along the installation direction 01 of the ink cartridge 100 , an ink supply portion 112 communicating with the ink storage chamber 111 is disposed on the front side of the shell 110 .

[0031] The air inlet 113 is disposed on the upper side of the housing 110 ; the ink storage chamber 11 is connected to the outside atmosphere through the air inlet 113 .

[0032] The sealing portion is used to seal the air inlet 113 .

[0033] The cover 120 (an example of a moving member) is movably mounted on the upper side of the housing 110 along the mounting direction 01 of the ink cartridge 100, and can move between a sealing position 101 for sealing the air inlet 113 and an unsealing position 102 for unsealing the air inlet 113. The sealing portion is provided on the moving member 120; Figure 2 and Figure 3 It can be seen that the moving direction of the moving member between the sealing position 101 and the unsealing position 102 for unsealing the air inlet 113 intersects with the opening direction of the air inlet 113. In this embodiment, the moving direction of the moving member is perpendicular to the opening direction of the air inlet.

[0034] When the ink cartridge 100 is installed in the ink cartridge holder 10 of the printer, the push rod 12 of the ink cartridge holder 10 pushes the cover 120 from the sealing position 101 to the unsealing position 102, and the air inlet 113 is connected to the outside atmosphere.

[0035] The cover 120 is movably installed on the upper side of the housing 110 along the installation direction 01 of the ink cartridge 100. The cover 120 directly seals the air inlet 113. The cover 120 does not need to pass through the air inlet 113. The maximum size of the cover 120 is not limited by the air inlet 113. The structure of the cover 120 can be made relatively solid and firm. The cover 120 moves along the installation direction 01 of the ink cartridge 100. The friction between the cover 120 and the push rod 12 of the ink cartridge holder 10 of the printer is small, and the cover 120 and the push rod 12 are not easily damaged.

[0036] Preferably, an elastic seal 121 (sealing part) is installed on the side of the cover 120 facing the air inlet 113. Preferably, the elastic seal 121 is made of rubber or silicone to improve the sealing quality.

[0037] Preferably, a guide portion 114 extending along the installation direction 01 of the ink cartridge 100 is formed on the housing 110 , and the cover 120 is slidably mounted on the housing 110 along the installation direction 01 of the ink cartridge 100 via the guide portion 114 .

[0038] Preferably, the guide portion 114 is a groove, and a protrusion 124 inserted into the groove is provided on the cover body 120. The structure is simple and reliable, easy to manufacture and install, and reduces the cost.

[0039] Preferably, the front side of the ink supply portion 112 is sealed by a sealing film 115. When the ink cartridge 100 is installed in the ink cartridge holder 10 of the printer, the ink extraction needle 11 pierces the sealing film 115.

[0040] As another embodiment, the cover 120 may be installed on the upper side of the housing 110 so as to be horizontally swingable around an axis extending along the height direction 03 .
