[0029] In the related art, inkjet printing devices such as DTF printers ("Direct to Film"), DTG printers ("Direct to Garment"), and the like can store ink liquid by using an ink cartridge structure, and in order to avoid the condensation of the ink liquid in the ink cartridge structure, a stirring device can be usually arranged in the ink cartridge structure to stir the ink liquid, so as to ensure the fluidity of the ink liquid in the ink cartridge structure. However, the stirring device is mostly arranged in an integrated structure on the ink cartridge structure, and a relatively large opening needs to be arranged on the ink cartridge structure for the stirring fan blades of the stirring device to enter and exit, which causes the ink liquid in the ink cartridge structure to be easily splashed out of the opening, and there is a certain risk of ink leakage. It can be understood that when the inkjet printer is a DTF printer or a DTG printer, the ink cartridge structure can be a white ink cartridge of the inkjet printer, which can store the base color ink liquid used for the inkjet printer to spray after printing images or characters on the printing material. Since the ink liquid is prone to deposit and condense, the stirring mechanism can be used to continuously stir the ink liquid to maintain the fluidity of the ink liquid and ensure the stable ink supply of the ink cartridge structure.

[0030] The stirring device usually includes a motor and a stirring fan blade, and the motor drives the stirring fan blade to rotate in the ink cartridge, so as to continuously stir the ink liquid in the ink cartridge to prevent the ink liquid from condensing. In the production and assembly of the ink cartridge structure, the ink cartridge body and the stirring device are usually independently produced, and in the assembly, the stirring fan blade of the stirring device is inserted into the ink cartridge body through the opening on the surface of the ink cartridge body, and the motor is fixedly installed on the ink cartridge body. Furthermore, when the liquid level in the ink cartridge body is high or the rotating speed of the stirring fan blade is high, the ink liquid in the ink cartridge structure is easily splashed onto the surface of the ink cartridge body from the opening, which causes certain pollution and waste of ink liquid. In view of the above problems, the utility model provides an ink cartridge structure 100.

[0031] Please refer to Figures 1 to 6 In an embodiment of the utility model, the ink cartridge structure 100 includes an ink cartridge body 10 and a stirring mechanism 30, the ink cartridge body 10 is formed with an ink cavity 10a, the ink cartridge body 10 includes opposite first wall 111 and second wall 131, first wall 111 is equipped with mounting hole 113;Stirring mechanism 30 includes drive device 31 and stirring fan blade 33, drive device 31 is located in ink cartridge body 10 and is located outside ink cavity 10a, stirring fan blade 33 is located in ink cavity 10a, one end of stirring fan blade 33 is arranged in mounting hole 113, and is connected with drive device 31, the other end of stirring fan blade 33 is rotatably connected to second wall 131.

At this time, the two ends of the stirring blade 33 can respectively abut against the first wall 111 and the second wall 131, effectively preventing the stirring blade 33 from spinning and deviating during operation, and the end size of the stirring blade 33 is set corresponding to the mounting hole 113, which can effectively reduce the ink splashing in the ink cartridge body 10, achieve a better anti-ink leakage effect of the ink cartridge structure 100, and further improve the practicality and structural reliability of the ink cartridge structure 100. Among them, the ink cartridge structure 100 can make the ink cartridge body 10 adopt a detachable double-layer structure, so that the stirring blade 33 can be better accommodated and installed in the ink cavity 10a, ensuring the installation of the stirring blade 33 in the ink cavity 10a. Of course, there are many ways to assemble the ink cartridge body 10 and the stirring blade 33, and this application does not limit this.

Because stirring fan blade 33 is set in ink cartridge body 10, can very good reduce the size of mounting hole 113, is favorable to reduce the ink liquid splash in ink cartridge body 10, realizes the better leakproof effect of ink cartridge structure 100, and can better dismouting maintenance drive device 31, effectively improve the practicality and structural reliability of ink cartridge structure 100.

[0036] Referring to Figure 2 And Figure 4 In an embodiment of the utility model, the stirring fan blade 33 includes a shaft body 331, a blade 333, and a connecting column 335. The shaft body 331 has a first end and a second end opposite to each other, and the first end is rotatably connected to the second wall 131. The blade 333 is arranged on the circumferential side of the shaft body 331. The connecting column 335 is connected to one end of the shaft body 331 facing the first wall 111. The cross-sectional width of the connecting column 335 is smaller than that of the shaft body 331. The connecting column 335 is arranged in the mounting hole 113 and connected to the drive device 31.

The protrusion is inserted into the groove to ensure the stable rotation of the shaft body 331. Alternatively, the second wall 131 can have a protrusion arranged corresponding to the mounting hole 113, and the shaft body 331 can have a groove arranged on the first end facing the second wall 131. The groove is correspondingly arranged on the protrusion to ensure the stable rotation of the shaft body 331 on the second wall 131. Of course, the shaft body 331 can also be connected to the second wall 131 in other rotating structures, which can ensure the stable and limited rotation of the shaft body 331 on the second wall 131. The application is not limited in this regard.

[0038] And by setting the connecting column 335 on the second end of the shaft body 331 towards the first wall 111, the cross-sectional width of the connecting column 335 can be smaller than the cross-sectional width of the shaft body 331, by setting the connecting column 335 through the mounting hole 113, the cross-sectional width of the mounting hole 113 can be greater than or equal to the cross-sectional width of the connecting column 335, and the cross-sectional width of the mounting hole 113 is smaller than the cross-sectional width of the shaft body 331, so that the stirring fan blade 33 can be limited by abutting the first wall 111 and the second end of the shaft body 331 when rotating in the ink cartridge body 10, preventing the stirring fan blade 33 from being removed from the ink cartridge body 10, ensuring the stable assembly of the stirring fan blade 33 in the ink cartridge body 10, and further improving the practicability and structural reliability of the ink cartridge structure 100.

[0045] Referring to Figure 2 and Figure 3In an embodiment of the present application, the stirring fan blade 33 is internally provided with a limiting hole 3313, the limiting hole 3313 is in communication with the connecting groove 3311, the cross-sectional width of the limiting hole 3313 is smaller than that of the connecting groove 3311, the end of the protrusion 133 away from the second wall is provided with a limiting boss 135, and the limiting boss 135 is inserted into the limiting hole 3313.

[0046] In the embodiment, the stirring fan blade 33 can be internally provided with the limiting hole 3313 in communication with the connecting groove 3311, and by providing the limiting boss 135 at the end of the protrusion 133 away from the second wall, the limiting boss 135 can be inserted into the limiting hole 3313 when the stirring fan blade 33 is cooperatively inserted and installed with the protrusion 133, and the rotation of the stirring fan blade 33 can be limited by the abutment of the limiting boss 135 and the inner wall of the limiting hole 3313. Furthermore, under the action of the limiting boss 135, the left and right deviation of the stirring fan blade 33 during rotation can be well reduced, and the dislocation of the stirring fan blade 33 in the ink cartridge body 10 can be avoided, so that the rotation friction of the stirring fan blade 33 is not too large, the stirring fan blade 33 can rotate more stably around the central axis of the protrusion 133, and the stability and reliability of the ink cartridge structure 100 are further improved.

[0047] Referring to Figure 2 and Figure 3 In an embodiment of the present application, the protrusion 133 is conical, and the inner wall of the connecting groove 3311 is attached to the outer periphery of the protrusion 133.

[0048] In the embodiment, the protrusion 133 can be conical in structure, so that the cross-sectional size of the protrusion 133 can be gradually reduced from the second wall 131 to the first wall 111, and thus the limiting effect of the stirring fan blade 33 can be achieved by the conical protrusion 133, so that the stirring fan blade 33 can rotate better according to the rotation center axis of the protrusion 133 during rotation, and the stirring mechanism 30 can more stably and reliably stir the ink liquid in the ink cartridge body 10, the maintenance frequency of the stirring mechanism 30 is reduced, and the practicability and reliability of the ink cartridge structure 100 are further improved.

[0050] In the embodiment, the stirring vane 33 can be bent outward at the end of the second wall 131 to extend a certain thickness at the notch of the connecting groove 3311, so that a surrounding edge 3315 is formed at the outer periphery of the end of the stirring vane 33, which can be arranged around the connecting groove 3311 to strengthen the structure of the stirring vane. When the stirring vane 33 is arranged in the ink cavity 10a, the end surface of the surrounding edge 3315 can abut against the second wall 131, so that the stirring vane 33 has a larger contact area with the second wall 131, thereby ensuring the stable arrangement of the stirring vane 33 in the ink cavity 10a. When the stirring vane 33 is rotatably connected to the second wall 131 by the connecting groove 3311 and the protrusion 133, the inner wall of the connecting groove 3311 is easy to abut against the inner wall of the protrusion 133 to interact, thereby causing the end of the stirring vane 33 to be subjected to a certain force from the side of the second wall 131. At this time, under the action of the surrounding edge 3315, the stirring vane 33 can be well prevented from being broken due to the excessive force on the end, which is beneficial to better protect the overall structure of the stirring vane 33, so that the stirring vane 33 can be more stably and reliably arranged in the ink cartridge body 10, and the stability and reliability of the ink cartridge structure 100 are further improved.

[0051] In addition, the stirring vane 33 can also make the surrounding edge 3315 flush with the end surface of the stirring vane 33 facing the second wall 131, so that the stirring vane 33 can abut against the second wall 131 by the surrounding edge 3315, which is beneficial to better increase the contact area of the stirring vane 33 with the ink cartridge body 10, and ensure the limited rotation of the stirring vane 33 in the ink cartridge body 10, and better prevent the stirring vane 33 from rotating and deviating.

[0052] Referring to Figure 2 and Figure 3 In an embodiment of the present application, the second wall 131 is provided with a boss 137 connected to one end of the protrusion 133 away from the first wall 111 and arranged around the protrusion 133, and the surrounding edge 3315 abuts against the boss 137.
