Description

Technical Field

[0001] The utility model relates to the technical field of inkjet imaging, in particular to an ink cartridge used for inkjet imaging equipment. Background Art

[0002] An ink cartridge is a consumable material for an inkjet imaging device. An ink suction needle is provided in the imaging device. The ink cartridge includes a surface cover and a shell body combined with each other, and an ink cavity formed between the surface cover and the shell body. The ink cavity is used to accommodate ink required for imaging by the imaging device. The ink cartridge also includes an ink outlet portion, a first sealing member and a second sealing member. The ink outlet portion is connected to the ink cavity. An ink outlet port is provided on the ink outlet portion. The ink suction needle can pass through the ink outlet port, so that the ink in the ink cavity is supplied to the imaging device via the ink suction needle. The first sealing member is provided in the ink outlet portion to prevent the ink outlet from leaking ink when the ink suction needle enters the ink outlet. The second sealing member is used to seal the ink outlet port.

[0003] The ink cartridge is also provided with an air guide port and an air guide cavity which are interconnected. The air guide cavity is connected with the ink cavity. The atmosphere can enter from the air guide port and reach the ink cavity via the air guide cavity, so that the atmosphere is connected with the ink cavity.

[0004] In order to reduce the user's operating steps and prevent the air port from being opened after the ink cartridge is installed in the imaging device, there are ink cartridges that connect the air port with the ink outlet. Before the ink cartridge is used, the second seal seals the ink outlet and the air port together; however, during the assembly of the first seal, the first seal may not be installed in place or the first seal may be displaced. In this case, the air port is easily blocked by the first seal. After the ink suction needle passes through the second seal, the atmosphere cannot reach the ink cavity through the air port, so that the ink cavity cannot be connected to the atmosphere, affecting the normal use of the ink cartridge.

For example, the second sealing member 50 is set to a flexible film; the chip 30 is used to store parameter information of the ink cartridge 100, and the chip 30 is set on the box body 10. The handle 40 is connected to the box body 10, and the handle 40 is convenient for the user to take and place the ink cartridge 100.

[0016] like Figure 1 and Figure 2 As shown, the box body 10 includes a face cover 11, a shell body 12 and an ink cavity 13 formed between the face cover 11 and the shell body 12, the ink cavity 13 is used to contain ink, and the ink cavity 13 can be set as one or more cavities connected to each other; the ink outlet portion 20 is arranged on the shell body 12, the ink outlet portion 20 is connected to the ink cavity 13, the ink outlet portion 20 can be combined with an ink suction needle so that ink is supplied to the imaging device, in addition, the ink outlet portion 20 is also provided with an ink outlet port 21, the ink suction needle can enter the ink outlet portion 20 through the ink outlet port 21, and before the ink cartridge 100 is used, the ink outlet port 21 is sealed by the second sealing member 50.

[0017] The ink cartridge also includes an air guide component 60 for connecting the ink chamber 13 with the atmosphere. The air guide component 60 includes an air guide port 61 and an air guide cavity 62 that are interconnected. The air guide cavity 62 is also connected to the ink chamber 13. The air guide cavity 62 can also be set as one or more interconnected cavities. The atmosphere enters through the air guide port 61 and then reaches the ink chamber 13 through the air guide cavity 62, so that the ink chamber 13 is connected to the atmosphere; the air guide port 61 is connected to the ink outlet 21. For example, the air guide port 61 is set on the inner wall 22 of the ink outlet part 20. When the ink suction needle passes through the second sealing member 50, the air guide port 61 is also opened, and the atmosphere can reach the air guide port 61 from the ink outlet 21.
