[0035] Figures 1 to 6 The ink cartridge unit provided by the present utility model is shown. As can be seen from the figure, the present utility model provides an ink cartridge unit, which includes a printing mechanism 100 and an ink storage mechanism 200; the printing mechanism 100 has an ink inlet hole 1120; the ink storage mechanism 200 has an ink storage chamber 2100 and a first ink outlet hole 2220 that can communicate with the ink storage chamber 2100, and the ink storage mechanism 200 can be inserted into or separated from the printing mechanism 100; wherein, the first ink outlet hole 2220 and the ink inlet hole 1120 are in communication in the inserted state to supply ink from the ink storage mechanism 200 to the printing mechanism 100.

[0036] In specific implementation, the present utility model aims to solve the problem that the ink storage mechanism 200 of the ink cartridge unit in the prior art cannot be replaced separately, thereby reducing the cost for users to use the printer. Specifically, such an ink cartridge unit includes two main parts: a printing mechanism 100 and an ink storage mechanism 200. As Figure 6As shown, the printing mechanism 100 is designed with an ink inlet hole 1120, while the ink storage mechanism 200 is provided with an ink storage chamber 2100 and a first ink outlet hole 2220 connected to the ink storage chamber 2100. The innovation of these two parts lies in that the printing mechanism 100 and the ink storage mechanism 200 can be plugged into or separated from each other. When they are plugged together, the first ink outlet hole 2220 of the ink storage mechanism 200 is connected and communicated with the ink inlet hole 1120 of the printing mechanism 100, enabling the ink to flow smoothly from the ink storage mechanism 200 to the printing mechanism 100. This design allows users to only replace the ink storage mechanism 200 when the ink runs out, while continuing to use the original printing mechanism 100, that is, without replacing the printing mechanism 100, only replacing the ink storage mechanism 200, which greatly improves the flexibility and economy of the ink cartridge unit. In this way, users can maintain and use the printer more economically, reducing the additional costs caused by frequent replacement of the ink cartridge unit.

[0037] As Figure 1 and Figure 2 shown, according to an embodiment of the present invention, the first ink outlet hole 2220 and the ink inlet hole 1120 are disconnected and not communicated in the separated state.

[0038] As Figure 3 shown, according to an embodiment of the present invention, the printing mechanism 100 includes a housing 110 and a printing head 120; the housing 110 has an ink inlet hole 1120, a second ink outlet hole and an ink storage chamber; the ink inlet hole 1120 is communicated with the first ink outlet hole 2220 through the ink storage chamber; the printing head 120 is arranged at the second ink outlet hole, and the printing head 120 has ink jet holes.

[0039] In specific implementation, such a design ensures that the ink can flow smoothly from the ink storage mechanism 200 into the printing mechanism 100. The printing head 120 is installed at the second ink outlet hole. The nozzle itself has ink jet holes and is responsible for jetting the ink onto the printing medium to achieve the printing function. The housing 110 and the printing head 120 are designed as an integral module. This design enables the position of the printing head 120 relative to the housing 110 to remain unchanged when the ink storage mechanism 200 is replaced. This modular design concept brings significant advantages: First, it reduces the risk of damage to the printing head 120 caused by frequent replacement of the ink storage mechanism 200; second, keeping the position of the printing head 120 stable avoids the problem of affecting the printing effect due to the change of the nozzle position. Therefore, this design not only improves the usability of the ink cartridge unit, but also ensures the printing quality and the durability of the printing head. Through this design, when users replace the ink storage mechanism 200, they can operate easily without worrying about the change of the position of the printing head 120, thus ensuring the consistency of the printing effect and the long-term stable use of the printing head.

[0040] In this embodiment, the housing 110 can provide a support base for the print head 120; the print head 120 can be a prior art device, the print head 120 can have a plurality of ink jet holes, and the print head 120 can be located at the bottom of the housing 110.

[0041] As Figure 3 shown, according to an embodiment of the present invention, the housing 110 includes a support assembly 111 and a plug-in assembly 112; the support assembly 111 has a second ink outlet hole and an ink storage chamber; the print head 120 is disposed on the support assembly 111; the plug-in assembly 112 is disposed on the side wall of the support assembly 111, and an ink inlet hole 1120 is disposed on the plug-in assembly 112; the plug-in assembly 112 is inserted through the first ink outlet hole 2220 in a plugged state and contacts the hole wall surface of the first ink outlet hole 2220.

[0042] Specifically, in implementation, the printing mechanism 100 is composed of the housing 110 and the print head 120, and the housing 110 is further subdivided into a support assembly 111 and a plug-in assembly 112. The main function of the support assembly 111 is to fix the print head 120 to ensure the stability and accuracy of the print head 120 during the printing process. The print head 120 is installed on the support assembly 111, and the nozzle itself has ink jet holes and is responsible for ejecting ink onto the printing medium to complete the printing task. The plug-in assembly 112 is designed with an ink inlet hole 1120 and is disposed on the side wall of the support assembly 111. This design enables the plug-in assembly 112 to be inserted through the first ink outlet hole 2220 of the ink storage mechanism 200 in a plugged state with the ink storage mechanism 200. The ink inlet hole 1120 is communicated with the first ink outlet hole 2220 of the ink storage mechanism 200 through the ink storage chamber, thereby realizing the smooth supply of ink. The plug-in assembly 112 contacts the hole wall surface of the first ink outlet hole 2220 in the plugged state, ensuring the firmness of the connection.

[0043] In this embodiment, the second ink outlet hole can be located at the bottom of the support assembly 111, and the ink storage chamber can be located inside the support assembly 111; the plug-in assembly 112 can be a columnar structure extending laterally; the ink inlet hole 1120 is located on the side wall of the plug-in assembly 112 and can penetrate the side wall of the support assembly 111.

[0044] As Figure 2 and Figure 6 shown, according to an embodiment of the present invention, the plug-in assembly 112 is arranged as a guiding structure, and the outer diameter of the guiding structure is gradually expanded outward along the center line direction of the first ink outlet hole 2220.

[0045] During specific implementation, the outer diameter of the guiding structure is gradually expanded outward along the central line direction of the first ink outlet hole 2220, so that when the plugging component 112 is plugged into the ink storage mechanism 200, it can be more stably and accurately inserted into the first ink outlet hole 2220. The ink inlet hole 1120 is communicated with the first ink outlet hole 2220 of the ink storage mechanism 200 through an ink storage chamber, ensuring the continuity and smoothness of ink supply.

[0046] As Figure 2 and Figure 3 shown, according to an embodiment of the present invention, the support component 111 includes a first end 1101 and a second end 1102 oppositely arranged along its height direction H; the housing 110 further includes a connecting column 113; the connecting column 113 is arranged along the height direction H of the support component 111, one end of the connecting column 113 is connected to the first end 1101, and the other end of the connecting column 113 is used for connecting the output end of the motor of the rotary printer; the ink storage mechanism 200 and the printing mechanism 100 can be plugged or separated when the connecting column 113 is connected to the output end of the motor.

[0047] During specific implementation, the housing 110 further includes a connecting column 113, and the connecting column 113 is arranged along the height direction H of the support component 111. One end of the connecting column 113 is connected to the first end 1101 of the support component 111, and the other end is used for connecting the output end of the motor of the rotary printer. This design enables the printing mechanism 100 to be connected to the output end of the motor through the connecting column 113 to achieve power transmission. In particular, the plugging or separating operation of the ink storage mechanism 200 and the printing mechanism 100 is carried out when the connecting column 113 is connected to the output end of the motor, ensuring the convenience of operation. When replacing, there is no need to first disconnect the connection between the ink cartridge unit and the motor, improving the efficiency of replacing the ink storage mechanism 200.

[0048] As Figure 4 and Figure 5 shown, according to an embodiment of the present invention, the height direction H of the support component 111 is the vertical direction; the side wall of the support component 111 has a groove 1110, and the groove 1110 penetrates through the first end 1101 and the second end 1102; the plugging component 112 is located in the groove 1110; preferably, the axial direction O of the plugging component 112 can be perpendicular to the height direction H of the support component 111.

[0049] During specific implementation, through the above structural settings, the horizontal plugging and unplugging of the ink storage mechanism 200 can be realized.

[0050] In some embodiments, the axial direction O of the plugging component 112 may not be perpendicular to the height direction H of the support component 111. For example, the included angle between the axial direction O of the plugging component 112 and the height direction H of the support component 111 may be 30 degrees, 45 degrees or 60 degrees, etc.

[0051] As Figure 3 and Figure 4 shown, according to an embodiment of the present utility model, the housing 110 further includes a first embedding component 114; the first embedding component 114 is located in the groove 1110, and is in contact with the side wall of the groove 1110, and the first embedding component 114 divides the groove 1110 into a first sub-groove 1111 and a second sub-groove 1112 arranged in sequence from bottom to top; the plugging component 112 is located in the second sub-groove 1112.

[0052] As Figures 2 to 6 shown, according to an embodiment of the present utility model, the ink storage mechanism 200 includes an ink storage component 210, a communication component 220 and a second embedding component 230; the ink storage component 210 has an ink storage cavity 2100 and an interface 2101; the interface 2101 can communicate with the bottom of the ink storage cavity 2100; the communication component 220 is arranged on the side wall of the ink storage component 210, and the communication component 220 is embedded in the second sub-groove 1112 in the state where the ink storage mechanism 200 is plugged into the printing mechanism 100; the communication component 220 has a setting port 2211, an inner cavity 2212 and a first ink outlet hole 2220; the periphery of the setting port 2211 is in contact with the periphery of the interface 2101; the setting port 2211 communicates with the first ink outlet hole 2220 through the inner cavity 2212; the second embedding component 230 is arranged at the bottom of the side wall of the ink storage component 210, and is located below the communication component 220, and is in contact with the communication component 220, and an avoidance cavity 231 is formed between the second embedding component 230 and the communication component 220, and the second embedding component 230 is embedded in the first sub-groove 1111 in the state where the ink storage mechanism 200 is plugged into the printing mechanism 100; the first embedding component 114 is embedded in the avoidance cavity 231 in the state where the ink storage mechanism 200 is plugged into the printing mechanism 100.

[0053] In specific implementation, the above structure can ensure the firmness of the plugged state, that is, in the state where the ink storage mechanism 200 is plugged into the printing mechanism 100, through the first embedding component 114, the communication component 220 and the second embedding component 230, the ink storage mechanism 200 and the printing mechanism 100 can be in close contact, that is, there are three connection points, upper, middle and lower, which ensures the connection strength and the ink storage mechanism 200 and the printing mechanism 100 will not be separated due to centrifugal force during use. In addition, since the communication component 220 is embedded in the second sub-groove 1112 in the state where the ink storage mechanism 200 is plugged into the printing mechanism 100, therefore, the communication component 220 can also play a role in protecting the plugging component 112, so that the plugging component 112 is not easily broken.

[0054] As Figure 6As shown, according to an embodiment of the present utility model, an ink absorption structure 2210 capable of communicating with the bottom of the ink storage chamber 2100 is provided at the bottom of the inner cavity 2212. The ink absorption structure 2210 is a structural member made of porous material, and the porous material can be cotton or sponge; the insertion assembly 112 is connected to the ink absorption structure 2210 in a state where the ink storage mechanism 200 and the printing mechanism 100 are inserted into each other.

[0055] In specific implementation, an ink absorption structure 2210 is provided in the inner cavity 2212 of the ink storage mechanism 200. The ink absorption structure 2210 is made of porous material and can efficiently absorb and store ink. In a state where the ink storage mechanism 200 and the printing mechanism 100 are inserted into each other, the insertion assembly 112 is connected to the ink absorption structure 2210, ensuring smooth ink supply. Specifically, since there is a height difference between the first ink outlet hole 2220 and the bottom of the ink storage chamber 2100, that is, if the liquid level in the ink storage chamber 2100 is lower than the first ink outlet hole 2220, the ink in the ink storage chamber 2100 cannot continue to be supplied to the printing nozzle 120, and there is a problem that the ink in the ink storage chamber 2100 needs to be replaced before it is used up; the present utility model uses the ink absorption structure 2210 to absorb the ink at the bottom of the ink storage chamber 2100. Since the insertion assembly 112 is connected to the ink absorption structure 2210 in a state where the ink storage mechanism 200 and the printing mechanism 100 are inserted into each other, the ink absorbed by the ink absorption structure 2210 can finally flow to the printing nozzle 120 through the insertion assembly 112.

[0056] As Figure 2 As shown, in this embodiment, the connection component 220 includes a ink guiding part 221 and an opening part 222; the lower end of the ink guiding part 221 is connected to the second embedding component 230. The ink guiding part 221 has a setting port 2211, an inner cavity 2212 and a conducting port 2213; the opening part 222 is arranged on the side wall of the ink guiding part 221 and forms an avoidance cavity 231 with the first embedding component 114 below it. The opening part 222 has a first ink outlet hole 2220; the setting port 2211 is sequentially communicated with the first ink outlet hole 2220 through the inner cavity 2212 and the conducting port 2213.

[0057] In specific implementation, both cotton and sponge have a large number of tiny pores, which can quickly absorb and hold ink, ensuring the continuity and stability of ink supply. The ink absorption structure 2210 made of these materials can not only provide sufficient ink reserve, but also evenly release ink during the printing process, thereby improving the printing quality and effect.

[0058] The present utility model also provides a rotary printer, including an ink cartridge unit as described in the above embodiment. The specific structure, working principle and beneficial effects of the ink cartridge unit are the same as those in the above embodiment, and will not be elaborated here.
