[0015] like Figure 1-Figure 5 As shown, an ink cartridge structure includes a shell body 1, the top of the shell body 1 has an injection end 2 and a pressing end 3 protruding from the outer surface, and the shell body 1 is provided with a sealed chamber 4 for storing ink. In this embodiment, the shell body 1 is divided into two parts, upper and lower, but it can also be other structural forms with stronger sealing, which depends on actual production. The chamber 4 is used to store ink and also serves as a temporary storage space for part of the air during use. The injection end 2 is for the insertion of a fountain pen or other pens, and the pin 6 is directly inserted to absorb ink, while the pressing end 3 is used as an operating part to control the absorption and release of ink.

[0016] The injection end 2 is provided with a socket 5 for inserting an ink pen, and the socket 5 is provided with a pin 6 communicating with the chamber 4. An extension end 7 corresponding to the injection end 2 is provided in the chamber 4, and the extension end 7 is annular in structure, and the inner diameter of the extension end 7 is larger than the inner diameter of the injection end 2. The injection end 2 and the extension end 7 are respectively provided with an upper connection seat 8 and a lower connection seat 9 fixed by threads. The upper connection seat 8 and the lower connection seat 9 are convenient for production and installation, suitable for fixing a pen or a pin 6, and the threaded connection has strong sealing performance. In addition, the injection end 2 and the extension end 7 can both enhance the structural strength.

[0017] The lower connection seat 9 is provided with a tube needle part 10 for the insertion of the pin 6, and the tube needle part 10 is connected with the insertion hole 5. The pin 6 is provided with a liquid inlet hole 11 with a side opening at the bottom end, which is conducive to the rapid discharge of ink for the pen to absorb. The pressing end 3 is a concave structure, and the side surface of the bottom end of the pressing end 3 has a connecting part 12 connected to the shell body 1, and the chamber 4 is provided with a groove 13 at the corresponding connecting part 12. One end of the cavity 14 is arranged at the groove wall of the groove 13, and the other end of the cavity 14 is arranged at the inner side of the top of the pressing end 3. The cavity 14 is relatively hidden and does not hinder the use of other structural designs.

[0018] The pressing end 3 is provided with a mounting hole 19, a pressure cover 15, a sealing cover 16, a movable seat 17 and a spring 18, the two ends of the spring 18 respectively abut the bottom of the mounting hole 19 and the movable seat 17, the pressure cover 15 is provided with an annular rib 20 at the opening of the mounting hole 19, the pressure cover 15 is threadedly connected with the pressing end 3, the sealing cover 16 is a stepped disc structure, the sealing cover 16 and the annular rib 20 are axially blocked and limited, the movable seat 17 is provided with a flange 21 on the outer wall, the flange 21 and the sealing cover 16 are axially blocked and limited, an upper movable cavity 22 is formed between the sealing cover 16, the movable seat 17 and the pressing end 3, a lower movable cavity 23 is formed between the movable seat 17 and the pressing end 3, a cavity 14 communicating with the upper movable cavity 22 and the chamber 4 is provided, and an air hole 24 connected to the lower movable cavity 23 is provided on the movable seat 17. Before the cavity 14 is completely isolated, the upper movable cavity 22 can be regarded as connected to the chamber 4 to form a relatively closed space, which is compressed or expanded with the movement of the movable seat 17, thereby further affecting the airflow direction, air pressure and ink flow. The annular rib 20, on the one hand, limits the detachment of components, and on the other hand, plays an auxiliary sealing role. It should be noted that a plurality of reinforcing ribs 25 are provided on the flange 21 of the movable seat 17, and the sealing cover 16 is adapted to the reinforcing ribs 25 to improve the structural strength. The lower movable cavity 23 is connected to the outside world, while the upper movable cavity 22 is in a linkage state with the closed space volume of the chamber 4, that is, an approximately inversely proportional relationship. The movable seat 17 is provided with a sealing ring 26 and a sealing groove 27 for installing the sealing ring 26 on the side wall of the flange 21 to improve air tightness.
