[0033] Figures 1 to 7 The present utility model provides a cartridge unit, including a printing mechanism 100 and an ink storage mechanism 200; the printing mechanism 100 has a first ink outlet 1110; the ink storage mechanism 200 is detachably arranged on the printing mechanism 100, and the ink storage mechanism 200 has an ink storage chamber 210 and a second ink outlet 220; the ink storage chamber 210 is communicated with the first ink outlet 1110 through the second ink outlet 220.

[0034] In specific implementation, the present utility model provides a printing solution with a more flexible structure and higher cost-effectiveness. This design of the cartridge unit allows for a detachable connection between the ink storage mechanism 200 and the printing mechanism 100. In this way, when the ink runs out, the user does not need to replace the entire cartridge unit, but only needs to replace the ink storage mechanism 200. This design not only reduces resource waste but also lowers the user's usage cost. By communicating the ink storage chamber 210, the second ink outlet 220 of the ink storage mechanism 200 and the first ink outlet 1110 of the printing mechanism 100, the continuous supply of ink during the printing process and smooth printing are ensured. The technical problem in the prior art that the ink storage mechanism 200 cannot be replaced separately is solved.

[0035] Such as Figure 1 and Figure 4As shown, according to an embodiment of the present utility model, the printing mechanism 100 includes a housing 110 and a printing head 120; the housing 110 has an ink inlet 1111, a first ink outlet 1110 and an ink storage chamber 1112; the ink inlet 1111 communicates with the first ink outlet 1110 through the ink storage chamber 1112; the printing head 120 is disposed on the housing 110; the printing head 120 is disposed at the first ink outlet 1110; a second ink outlet 220 communicates with the ink inlet 1111; the ink storage mechanism 200 is detachably disposed on the housing 110.

[0036] Specifically, the printing mechanism 100 of the ink cartridge unit is composed of a housing 110 and a printing head 120. The housing 110 is internally designed with an ink inlet 1111, a first ink outlet 1110 and an ink storage chamber 1112, and these components are interconnected to form an internal ink delivery channel. The printing head 120 is connected to the housing 110, and the printing head 120 is connected to the first ink outlet 1110, ensuring that ink can flow smoothly from the ink storage mechanism 200 to the printing head 120 for printing through the printing head 120. At the same time, the second ink outlet 220 of the ink storage mechanism 200 is connected to the ink inlet 1111 of the housing 110, enabling ink to smoothly enter the ink storage chamber 1112 of the housing 110 and then flow to the printing head 120 through the first ink outlet 1110. By being detachably disposed, the replacement of the ink storage mechanism 200 becomes more convenient, further reducing the user's maintenance cost. In addition, when replacing the ink storage mechanism 200, the positions between the housing 110 and the printing head 120 do not change. Therefore, after replacing the ink storage mechanism 200, the printing accuracy is not affected, ensuring the success rate of replacing the ink storage mechanism 200.

[0037] As Figure 3 shown, in this embodiment, the printing head 120 can be an existing technology.

The ink inlet 1111 is designed on the cavity wall of the receiving cavity 1113 and is connected to the second ink outlet 220 of the ink storage mechanism 200, ensuring that ink can smoothly enter the ink storage chamber 1112 of the housing 110.

[0040] As Figure 3As shown, according to an embodiment of the present utility model, the housing 110 includes a receiving member 111 and a cover plate 112; the receiving member 111 includes a first end 1101 and a second end 1102 oppositely arranged along its height direction H; an ink inlet 1111, a first ink outlet 1110, an installation opening 1114, an ink storage chamber 1112 and a receiving cavity 1113 are provided on the receiving member 111; the installation opening 1114 is located at the first end 1101; the first ink outlet 1110 is located at the second end 1102; the print head 120 is provided on the second end 1102; the cover plate 112 is movably connected to the first end 1101, and the cover plate 112 can be switched between an open position and a closed position through the movable connection, wherein the installation opening 1114 is exposed when the cover plate 112 is in the open position; the ink storage mechanism 200 is clamped between the cover plate 112 and the bottom of the receiving cavity 1113 when the cover plate 112 is in the closed position.

[0041] During specific implementation, the cover plate 112 can be switched between an open position and a closed position. When the cover plate 112 is in the open position, the installation opening 1114 is exposed, facilitating the user to install or replace the ink storage mechanism 200; when the cover plate 112 is closed, the ink storage mechanism 200 is firmly clamped between the cover plate 112 and the bottom of the receiving cavity 1113, ensuring the stability of the ink cartridge unit during the printing process. At the same time, the opening and closing design of the cover plate 112 also provides an intuitive feedback mechanism for the user. By observing the position of the cover plate 112, the user can quickly judge whether the ink cartridge unit is in the correct installation state, thus ensuring the smooth progress of the printing work. In addition, the design of the cover plate 112 also takes into account the convenience of user operation, making the entire replacement process more smooth and user-friendly.

[0044] During specific implementation, when the cover plate 112 is in the closed position, the cover locking assembly 130 can firmly connect the cover plate 112 to the accommodating member 111. This design ensures that the cover plate 112 will not accidentally open during the printing process, improving the reliability of printing. The presence of the cover locking assembly 130 also provides a clear operation feedback to the user, that is, when the cover plate 112 is correctly locked, the user can intuitively know that the ink cartridge unit is ready and the printing job can be started.

[0045] As Figure 3 shown, according to an embodiment of the present invention, the cover locking assembly 130 includes a detachable locking member 131 and a locking mating member 132; the locking member 131 is disposed on the cover plate 112, and the locking mating member 132 is disposed on the side wall of the accommodating member 111; alternatively, the locking mating member 132 is disposed on the cover plate 112, and the locking member 131 is disposed on the side wall of the accommodating member 111.

[0046] As Figure 3 shown, in this embodiment, the locking member 131 is a buckle; the locking mating member 132 is a slot.

[0047] In some embodiments, the cover locking assembly 130 can be double-sided tape.

[0048] In a feasible embodiment, the printing mechanism 100 may further include a connection assembly 140. The connection assembly 140 is disposed on the cover plate 112, and the connection assembly 140 can connect to the output shaft of the motor of the rotary printer.

[0049] During specific implementation, by disposing the connection assembly 140 on the cover plate 112, the connection with the output shaft of the rotary printer motor is achieved. This design allows the ink cartridge unit to closely cooperate with the printer motor, ensuring stability and accuracy during the printing process.

[0050] As Figure 3 shown, in another feasible embodiment, the ink storage mechanism 200 has a first avoidance through hole 230 disposed along the height direction H of the accommodating member 111; the cover plate 112 has a second avoidance through hole 1120; the printing mechanism 100 further includes a connection assembly 140 for connecting to the output shaft of the motor of the rotary printer.
