[0076] (Air path and ink cavity)

[0077] When the air guide member 110 / air guide rod 110a is located at the unsealing position, the ink cavity 106 is in communication with the atmosphere, so as to keep the pressure in the ink cavity 106 stable; optionally, the ink cartridge 100 is further provided with an atmosphere path 120 (gas flow channel 140) in communication with the air guide port 110b, the atmosphere path 120 is used to communicate the ink cavity 106 and the air guide port 110b, preferably, the atmosphere path 120 is at least configured in three sections, specifically, at least a part of a first section 122 (hereinafter referred to as "first section 122") of the atmosphere path 120 is located in the first accommodating cavity 107m, a second section 123 (hereinafter referred to as "second section 123") of the atmosphere path 120 is located between the first partition 107a1 and the ink cavity 106, and a third section 124 (hereinafter referred to as "third section 124") of the atmosphere path 120 is located between the fourth partition 107a2 and the ink cavity 106, the second section 123 is used to connect the first section 122 and the third section 124, the third section 124 is in communication with the ink cavity 106, and the first section 122 and the third section 124 are respectively located at two ends of the ink cavity 106 along the up-down direction or the front-rear direction of the ink cartridge 100, preferably, at least one of the first section 122 and the third section 124 can be configured as a curved labyrinth, and the second section 123 can be configured as a long and narrow pipeline, generally, the labyrinth occupies a larger space, so that the atmosphere path can not only prolong the flow path of the atmosphere and slow down the flow speed of the atmosphere, but also make full use of the space in the ink cartridge 100.

[0078] Optionally, a buffer zone 121 (i.e. the gas buffer zone 141 described below) is provided between the first section 122 and the third partition 107m3, and the buffer zone 121 is at least used to install a buffer member such as a sponge, which can filter air and slow down air flow, further, the buffer member can also prevent ink backflow, and further, the buffer member can form a certain negative pressure in the ink cavity 106.

[0079] In this embodiment, the ink cavity 106 of the ink cartridge 100 is divided into a plurality of cavities in communication with each other by a plurality of side plates, so that the cartridge 1 is more versatile, and in the actual production process of the ink cartridge 100, the factory can select the capacity of the ink cavity 106 according to the model of the produced ink cartridge 100, when a large-capacity ink cartridge 100 is needed, all the cavities can be connected, and when a small-capacity ink cartridge 100 is needed, part of the cavities can be closed.

[0080] (Installation of the ink cartridge 100)

[0081] In this embodiment, as Figure 5As shown, when the ink cartridge 100 is in its initial uninstalled state, the air guide member 110 / air guide rod 110a is in a sealed position. Specifically, the rear surface 110f2 of the abutment portion 110f abuts against the extension portion 104b3 of the chip member 104, and the air guide port 110b is sealed by the sealing member 110d; the electrical contact portion 104a1 is in an electrically disconnected position, that is, the electrical contact portion 104a1 does not form an electrical connection with the electrical contact pin 340.

[0082] When the ink cartridge 100 is installed in the installation direction, such as Figure 6 and Figure 7 As shown, the gas guide member 110 is triggered by the actuating element, and the gas guide member 110 / gas guide rod 110a moves from the sealed position to the unsealed position. Specifically, the actuating element and the front surface 110f1 of the abutment portion 110f abut against and force the gas guide member 110 to move backward, and the first end 110g moves backward, causing the seal 110d to no longer be abutted by the first end 110g, and the seal of the gas guide port 110b is released. The rear surface 110f2 of the abutment portion 110f still abuts against the extension portion 104b3 of the chip component. The extension 104b3 receives a thrust from the abutment 110f, forcing the chip holder body 104b to move backward. The connector 104c undergoes elastic deformation. Under the action of the lifting component, the chip holder body 104b rotates upward around the sliding part 104b1. When the ink cartridge 100 reaches the installation state, the electrical contact 104a1 reaches the electrical connection position that forms an electrical connection with the electrical contact pin 340. The electrical connection between the electrical contact 104a1 and the electrical contact pin 340 is maintained through the abutment of the front surface 110f1 and the abutment of the actuating member.

[0083] (Resetting ink cartridge 100)

[0084] When the ink cartridge 100 is removed by moving backward, the air guide member 110 / air guide rod 110a moves from the unsealed position to the sealed position. Specifically, the front surface 110f1 of the abutment part 110f gradually disengages from the actuating member, the electrical contact part 104a1 disengages from the electrical contact pin 340 and reaches the electrically disconnected position, the connector 104c releases its elastic force to force the chip holder 104b to rotate downward, the extension part 104b3 of the chip member 104 and the rear surface 110f2 of the abutment part 110f abut against and force the air guide member 110 to move forward until the air outlet 110b is sealed by the sealing member 110d, and the air guide member 110 / air guide rod 110a reaches the sealed position.

[0085] In some embodiments, the air guide member 110 can further be provided with an elastic member for urging the air guide rod 110a to move towards the sealing position; during the movement of the ink cartridge 100 from the initial state to the mounted state, when the front surface 110f1 abuts against the acting member, the air guide rod 110a moves backward from the sealing position to the unsealing position, the elastic member is elastically deformed, at the same time, the chip seat body 104b is also moved backward by the abutment of the rear surface 110f2 against the extension 104b3 and is rotated upward around the sliding part 104b1, and the connecting member 104c is elastically deformed; during the movement of the ink cartridge from the mounted state to the initial state, when the front surface 110f1 is disengaged from the abutment against the acting member, the connecting member 104c releases the elastic force to urge the chip seat body 104b to move forward and rotate downward around the sliding part 104b1, at the same time, the elastic member also releases the elastic force to urge the air guide rod 110a to move forward from the unsealing position to the sealing position.

[0086] When the elastic member is provided in the air guide member 110, the rear surface 110f2 of the air guide member 110 can not abut against the extension 104b3 when the ink cartridge 100 is in the initial state, and the rear surface 110f2 abuts against the extension 104b3 only during the backward movement of the air guide rod 110a, which can prevent the front surface 110f1 from being accidentally impacted to cause the chip fixing seat 104b to rotate upward and damage the electrical contact part 104a1.

[0087] In the present embodiment, first, when the ink cartridge 100 is in the initial state, the upper end of the abutment part 110f is located above the electrical contact part 104a1 in the up-down direction, which can effectively protect the electrical contact part 104a1 by providing the abutment part 110f, and the abutment part 110f can be collided first when the ink cartridge 100 falls or is impacted, thereby protecting the electrical contact part 104a1.

[0088] Second, the ink cartridge 100 is provided with the air guide member 110, which can be triggered by the installation of the ink cartridge 100 to move the air guide member 110 from the sealing position to the unsealing position, and the air guide opening 110b is automatically opened without manual operation of the user, thereby improving the user experience.

[0089] Third, during the opening of the air guide opening 110b of the ink cartridge 100, the chip member 104 is driven upward by the air guide member 110 to form electrical connection between the electrical contact part 104a1 and the electrical contact pin 340, and the extension 104b3 of the chip member 104 is always in contact with the abutment part 110f of the air guide member 110, which can not only enhance the stability of the electrical connection between the electrical contact part 104a1 and the electrical contact pin 340, but also reduce the number of parts of the ink cartridge 100 and simplify the structure of the ink cartridge 100.
