[0048] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the scope of protection of the present application.

[0049] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplifying the present application, the components and settings of specific examples are described in the following. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeatedly refer to numbers and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, and it does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides examples of various specific processes and materials, but a person of ordinary skill in the art can realize the applicability of other processes and / or the use of other materials.

[0050] For the purpose of description, spatial relative terms can be used in the text to describe the relative position relationship or movement of one element or feature with respect to another element or feature as shown in the figure, such as "internal", "external", "inboard", "outboard", "under", "below", "on", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure is flipped over or the posture is changed or the movement state is changed, the directional indications will also change accordingly, for example: the element described as "under" or "below" another element or feature will be oriented as "above" or "above" another element or feature. Therefore, the example term "below" can include both up and down positions. The device can be additionally oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the text are interpreted accordingly.

[0051] To solve the technical problem of inconvenient dismounting and mounting of the ink cartridge, the present disclosure provides an ink cartridge assembly, an ink cartridge and an ink cartridge seat. In the ink cartridge assembly of the present disclosure, not only is a rebound device provided, but also the elastic member of the rebound device is arranged on the side of the ink cartridge body facing the corresponding mounting position on the ink cartridge seat. When the ink cartridge is mounted on the mounting position of the ink cartridge seat and the ink cartridge body and the ink cartridge seat are in a mutual locking state, the rebound force of the elastic member can drive the ink cartridge body to move away from the mounting position, thereby providing auxiliary power for the dismounting of the ink cartridge, greatly facilitating the dismounting operation of the ink cartridge, reducing the difficulty of the user in replacing the ink cartridge, and improving the use efficiency. Moreover, since the elastic member is arranged on the ink cartridge rather than the ink cartridge seat, the corresponding elastic member is also replaced when the ink cartridge is replaced, which can avoid the repeated use of the same elastic member when the ink cartridge is frequently replaced, and can prolong the service life of the rebound device.

[0052] In one exemplary embodiment, referring to Figures 1 to 4 An ink cartridge 1, an ink cartridge seat 2 and an ink cartridge assembly are provided. The ink cartridge assembly can include the above-mentioned ink cartridge seat 2 and at least one ink cartridge 1, wherein the ink cartridge seat 2 is provided with at least one mounting position 21, the number of mounting positions 21 is the same as the number of ink cartridges 1, and the mounting positions 21 are used to mount at least one ink cartridge 1 on the ink cartridge seat. That is, each mounting position 21 of the ink cartridge seat 2 is used to mount a corresponding ink cartridge 1.

[0053] For example, the ink cartridge seat 2 can include one mounting position 21, and the ink cartridge assembly can include one ink cartridge 1 mounted on the above-mentioned mounting position 21.

[0054] For another example, the ink cartridge seat 2 can include two mounting positions 21, respectively referred to as mounting position 21a and mounting position 21b; the ink cartridge assembly can include two ink cartridges 1, respectively referred to as ink cartridge 1A and ink cartridge 1B; wherein the ink cartridge 1A can be mounted on the mounting position 21a, and the ink cartridge 1B can be mounted on the mounting position 21b.

[0055] It should be noted that when the ink cartridge assembly includes more than one ink cartridge 1, the ink cartridges 1 in the ink cartridge assembly can be the same or different, and no limitation is made thereto.

[0056] In this embodiment, the ink cartridge assembly can include a rebound device, the ink cartridge 1 includes an ink cartridge body 11, and the elastic member 41 of the rebound device is arranged on the side of the ink cartridge body 11 facing the corresponding mounting position 21 on the ink cartridge seat 2. It should be noted that the ink cartridge 1 of this embodiment can be the first ink cartridge 10 in the above-mentioned embodiment, or it can be another ink cartridge 1, and no limitation is made thereto.

[0057] In the state that the ink cartridge 1 is installed in the corresponding installation site 21 (i.e. the ink cartridge body 11 and the installation site 21 are in the interlocked state), the resilience of the elastic member 41 is used to drive the ink cartridge body 11 to move in the direction away from the installation site 21. For example, in the ink cartridge 1 and the installation site 21 corresponding to each other, when the ink cartridge body 11 and the installation site 21 are in the interlocked state, the resilience of the elastic member 41 can drive the ink cartridge body 11 to move in the direction away from the installation site 21, so as to facilitate the dismounting of the ink cartridge 1 from the installation site 21.

[0058] That is to say, in the ink cartridge assembly, not only the resilience device is provided, but also the elastic member of the resilience device is arranged on the side of the ink cartridge body facing the corresponding installation site of the ink cartridge seat. In the state that the ink cartridge 1 is installed in the corresponding installation site 21 (i.e. the ink cartridge body 11 and the installation site 21 are in the interlocked state), the resilience of the elastic member 41 is used to drive the ink cartridge body 11 to move in the direction away from the installation site 21. Thus, the resilience of the elastic member 41 provides auxiliary power for the dismounting of the ink cartridge, greatly facilitates the dismounting operation of the ink cartridge, reduces the difficulty of the user to replace the ink cartridge, and improves the use efficiency. Moreover, since the elastic member is arranged on the ink cartridge rather than the ink cartridge seat, the corresponding elastic member is replaced at the same time when the ink cartridge is replaced, which can avoid the repeated use of the same elastic member caused by the frequent replacement of the ink cartridge, and can prolong the service life of the resilience device.

[0059] In addition, the ink cartridge body 11 can include a ventilation hole 12. The elastic member 41 can be located in the ventilation hole 12 and fixedly connected with the hole wall of the ventilation hole 12. For example, the elastic member 41 can be a spring, and the hole wall of the ventilation hole 12 can be provided with a plurality of clamping protrusions 131, and the spring can be hung on the clamping protrusions 131 to realize the fixed connection of the spring with the hole wall of the ventilation hole 12. Of course, the spring can also be fixed to the ventilation hole 12 in other ways, which is not limited.

[0060] In the state that the ink cartridge 1 is installed in the corresponding installation site 21, the elastic member 41 is in the elastic compression state, so that the resilience of the elastic member 41 can drive the ink cartridge body 11 to move in the direction away from the installation site 21.

[0061] When the elastic member 41 is a spring, the resilience device can further include a column 42, and the column 42 is arranged in the corresponding installation site 21. In the state that the ink cartridge 1 is installed in the corresponding installation site 21 (i.e. in the interlocked state that the ink cartridge body 11 and the installation site 21 are in the interlocked state), the spring is sleeved on the outer periphery of the column 42, and the spring can be in the compression state. Based on this, the resilience of the spring can give the ink cartridge 1 a movement trend in the direction away from the installation site 21.

[0062] In the embodiment, the elastic member is arranged in the air vent hole of the ink cartridge body and is fixedly connected with the elastic member through the clamping protrusion on the air vent hole wall. This structure design ingeniously utilizes the existing air vent hole structure of the ink cartridge body, does not need to additionally open up space to arrange the elastic member, effectively saves the internal space of the ink cartridge, and ensures the stability of the elastic member installation. Meanwhile, when the elastic member is a spring, the column arranged in the installation position is cooperated. In the ink cartridge installation state, the spring is sleeved on the outer periphery of the column and is in a compressed state. The column plays a guiding and limiting role on the spring, ensures the stability of the spring in the stretching and retracting process, accurately provides the springback force of the ink cartridge moving away from the installation position, and further improves the smoothness of the ink cartridge disassembly and installation.

[0063] In one example embodiment, referring to Figures 1 to 7 An ink cartridge 1, an ink cartridge seat 2 and an ink cartridge assembly are provided. In the embodiment, the ink cartridge assembly can include a locking mechanism cooperating with a springback device. When the ink cartridge 1 and the installation position 21 are in a separated state, the springback force of the springback device is used to drive the ink cartridge body 11 to move away from the installation position 21 after the locking mechanism moves to a first cut-off state, so that the locking mechanism moves to a locked state to lock the ink cartridge and the installation position. When the ink cartridge 1 and the installation position 21 are locked, the springback force of the springback device is used to drive the ink cartridge body 11 to move away from the installation position 21 after the locking mechanism moves to a second cut-off state, so that the locking mechanism moves to a free state to unlock the ink cartridge 1 and the installation position 21.

[0064] That is, the locking mechanism of the embodiment has four states: a first cut-off state, a second cut-off state, a locking state and a free state. During the installation of the ink cartridge 1, the user applies an external force to the ink cartridge 1, so that the ink cartridge 1 moves towards the installation position 21. With the movement of the ink cartridge 1 towards the installation position 21, the locking mechanism can gradually move from the free state to the first cut-off state. The locking mechanism in this state can prevent the ink cartridge 1 from continuing to move towards the installation position 21. At this time, when the user removes the external force to push the ink cartridge 1 towards the installation position 21, the rebound force of the rebound device can drive the ink cartridge body 11 to move away from the installation position 21. The movement of the ink cartridge body 11 away from the installation position 21 can make the locking mechanism continue to move until the locking mechanism moves to the locking state, so that the installation of the ink cartridge 1 is realized, that is, the installation of the ink cartridge 1 to the installation position 21 of the ink cartridge seat 2 is completed. During the disassembly of the ink cartridge 1, the user applies an external force to the ink cartridge 1, so that the ink cartridge 1 moves towards the installation position 21. With the movement of the ink cartridge 1 towards the installation position 21, the locking mechanism can gradually move from the locking state to the second cut-off state. The locking structure in this state can prevent the ink cartridge 1 from continuing to move towards the installation position 21. At this time, when the user removes the external force to push the ink cartridge 1 towards the installation position 21, the rebound force of the rebound device can drive the ink cartridge body 11 to move away from the installation position 21. The movement of the ink cartridge body 11 away from the installation position 21 can make the locking mechanism continue to move until the locking mechanism moves to the free state, so that the disassembly of the ink cartridge 1 is realized. In this case, the user can take the ink cartridge 1 off the ink cartridge seat 2.

[0065] In the embodiment, the locking mechanism can include a locking rod 13, which is rotatably connected with the ink cartridge body 11, so that the locking rod 13 can swing relative to the ink cartridge body 11. In addition, the ink cartridge 1 further includes a limiting cover 14, which is fixedly connected with the ink cartridge body 11, and the locking rod 13 is located between the limiting cover 14 and the ink cartridge body 11. The limiting cover 14 is used to limit the locking rod 13 from being separated from the ink cartridge body 11. It should be noted that the fixed connection here means that the limiting cover 14 can be fixed on the ink cartridge body 11. However, the limiting cover 14 can also be detached from the ink cartridge body 11. That is, the limiting cover 14 and the ink cartridge body 11 can be fixedly connected by means of detachable connection.

[0066] In the embodiment, the free end of the locking rod 13 can be provided with a protrusion 131. The locking mechanism can further include a sliding groove 211, which is arranged in the installation position 21 of the ink cartridge seat 2 corresponding to the ink cartridge 1. The protrusion 131 is adapted to the sliding groove 211, that is, the protrusion 131 can be clamped into the sliding groove 211 and can slide in the sliding groove 211 along the track of the sliding groove 211.

[0067] Wherein, when the ink cartridge 1 and the installation site 21 are in the separated state (i.e. the ink cartridge 1 is not installed in the installation site 21), the user can press or push the ink cartridge 1 to move towards the corresponding installation site 21, so that the protrusion 131 is clamped into the sliding groove 211. After the protrusion 131 is clamped into the sliding groove 211, as the ink cartridge 1 continues to move towards the installation site 21, the protrusion 131 can continue to move along the sliding groove 211. Until the ink cartridge 1 cannot further approach the installation site 21, the protrusion 131 moves to the first limit position along the sliding groove 211 (at this time, the locking mechanism is in the first cut-off state). After the protrusion 131 moves to the first limit position 100, the rebound force of the rebound device is used to drive the ink cartridge body 11 to move away from the installation site 21. That is, after the protrusion 131 moves to the first limit position 100, if the user removes the external force applied to the ink cartridge 1, the rebound force of the rebound device can drive the ink cartridge body 11 to move away from the installation site 21, so that the protrusion 131 moves to the locking position 300 in the sliding groove 211 (at this time, the locking mechanism is in the locked state), to lock the ink cartridge 1 and the installation site 21 with each other, thereby achieving the installation of the ink cartridge 1.

[0068] Wherein, when the ink cartridge 1 and the installation site 21 are in the separated state (i.e. the ink cartridge 1 is not installed in the installation site 21), the user can press or push the ink cartridge 1 to move towards the corresponding installation site 21, so that the protrusion 131 is clamped into the sliding groove 211. After the protrusion 131 is clamped into the sliding groove 211, as the ink cartridge 1 continues to move towards the installation site 21, the protrusion 131 can continue to move along the sliding groove 211. Until the ink cartridge 1 cannot further approach the installation site 21, the protrusion 131 moves to the first limit position along the sliding groove 211 (at this time, the locking mechanism is in the first cut-off state). After the protrusion 131 moves to the first limit position 100, the rebound force of the rebound device is used to drive the ink cartridge body 11 to move away from the installation site 21. That is, after the protrusion 131 moves to the first limit position 100, if the user removes the external force applied to the ink cartridge 1, the rebound force of the rebound device can drive the ink cartridge body 11 to move away from the installation site 21, so that the protrusion 131 moves to the locking position 300 in the sliding groove 211 (at this time, the locking mechanism is in the locked state), to lock the ink cartridge 1 and the installation site 21 with each other, thereby achieving the installation of the ink cartridge 1.

[0069] The mounting position 21 corresponding to the ink cartridge 1 on the ink cartridge seat 2 can be provided with a guide structure 212, for example, a guide plate. When the ink cartridge 1 needs to be installed, as the ink cartridge 1 moves towards the mounting position 21, the free end of the locking rod 13 in the ink cartridge 1 can abut against the guide structure 212. As the ink cartridge 1 continues to move towards the mounting position 21, the free end of the locking rod 13 can slide along the guide mechanism until the protrusion 131 of the free end of the locking rod 13 is clamped into the sliding groove 211. In this embodiment, by providing the guide structure 212, the protrusion 131 on the locking rod 13 can be well guided into the sliding groove 211. The guide structure 212 can accurately guide the protrusion 131 on the locking rod 13 into the sliding groove 211, avoiding the problem that the protrusion 131 cannot be accurately clamped into the sliding groove 211 during installation. The presence of the guide structure 212 makes the installation of the ink cartridge 1 more smooth, reduces the mistakes and debugging time during installation, and improves the success rate and efficiency of installation.

[0070] In some embodiments, the second limit position 200 is close to the outlet position 400 of the card slot relative to the first limit position 100. When the ink cartridge 1 is locked with the mounting position 21, under the action of gravity, the free end of the locking rod 13 can have a movement trend towards the outlet position 400 of the sliding groove 211. Based on this, when the ink cartridge 1 moves towards the mounting position 21 again, the protrusion 131 can slide along the sliding groove 211 to the second limit position 200 without returning to the first limit position 100. In this embodiment, when the ink cartridge 1 is locked with the mounting position 21, under the action of gravity, the free end of the locking rod 13 has a trend of moving towards the outlet position 400 of the sliding groove 211. This feature makes the protrusion 131 more smoothly slide along the sliding groove 211 to the second limit position 200 when the ink cartridge 1 is disassembled, without the need for additional complex operations, further simplifying the disassembly process, and embodying the design of humanization and rationality.

[0071] In some embodiments, the slide groove 211 can include a first slide section 2111, a second slide section 2112, a third slide section 2113 and a fourth slide section 2114 connected in sequence. The protrusion 131 can slide along the first slide section 2111 to the first limit position 100, slide along the second slide section 2112 to the locking position 300, slide along the third slide section 2113 to the second limit position 200, and slide along the fourth slide section 2114 to the outlet position 400 of the slot. When the protrusion 131 is at the locking position 300, the position of the protrusion 131 coincides with the position of the third slide section 2113 in the vertical direction. Therefore, as the ink cartridge 1 moves towards the installation position 21, the protrusion 131 can enter the third slide section 2113 under the action of gravity to slide along the third slide section 2113 to the second limit position 200. In this embodiment, the slide groove 211 is designed with the first slide section 2111, the second slide section 2112, the third slide section 2113 and the fourth slide section 2114 connected in sequence, which provides a clear trajectory for the movement of the protrusion 131, making the installation and removal process of the ink cartridge 1 more orderly. The arrangement of different slide sections can adapt to the movement requirements of the ink cartridge 1 at different stages, ensuring that the protrusion 131 can accurately reach each key position (such as the first limit position 100, the locking position 300, the second limit position 200 and the outlet position 400), and realizing reliable locking and unlocking functions.

[0072] It should be noted that the slide groove 211 can be configured in other structures besides the above configuration, which is not limited.

[0073] In addition, many ink cartridge assemblies in the related art do not have a rebound device, or the spring of the rebound device is arranged on the ink cartridge seat 2, but the spring has a fatigue characteristic and will fail after a long period of use. After failure, the ink cartridge 1 cannot be correctly locked and unlocked, and the user experience is poor. In this embodiment, the elastic member 41 of the rebound device is arranged on the ink cartridge 1, i.e., each ink cartridge 1 has a separate elastic member 41, which can better avoid the failure of the rebound effect of the elastic device. Moreover, in this embodiment, the user only needs to simply press or push the ink cartridge 1 towards the installation position 21 to complete the installation of the ink cartridge 1. The protrusion 131 on the locking rod 13 smoothly enters the slide groove 211 under the guidance of the guide structure 212, and then the ink cartridge 1 automatically completes the locking under the combined action of the rebound force of the rebound device and the trajectory of the slide groove 211, without complex installation steps. When disassembling, the ink cartridge 1 is also pressed or pushed, and the rebound force of the rebound device is used to realize unlocking, so that the ink cartridge 1 is easily removed from the installation position 21. This simple operation method reduces the user's usage threshold, and even users who are not familiar with the equipment can quickly get started.

[0074] In addition, the cooperation between the rebound device and the sliding groove 211 ensures the stable locking of the ink cartridge 1 on the installation site 21. When the protrusion 131 moves to the locking position 300 of the sliding groove 211, the ink cartridge 1 is tightly connected with the installation site 21, which can effectively prevent the ink cartridge 1 from loosening or falling off due to vibration, shaking or other external forces during use, thereby ensuring the good electrical connection between the ink cartridge 1 and the equipment and the stability of the ink supply, and improving the printing quality and the reliability of the equipment.

[0075] When the ink cartridge 1 needs to be disassembled, the protrusion 131 can accurately move from the locking position 300 to the second limit position 200 and then to the exit position 400 under the action of the rebound force of the rebound device by pressing or pushing the ink cartridge 1, thereby realizing accurate unlocking. This accurate unlocking mechanism avoids problems such as damage to the ink cartridge 1 or the installation site 21 caused by incomplete unlocking or misoperation, thereby prolonging the service life of the ink cartridge 1 and the equipment.

[0076] In this embodiment, the rebound device is provided in the form of an elastic member 41 (such as a spring) arranged in the air hole 12, which not only saves space but also stores elastic potential energy during the installation of the ink cartridge 1. When the ink cartridge 1 needs to be installed or disassembled, the elastic member 41 releases the rebound force to drive the ink cartridge body 11 to move, thereby realizing automatic locking and unlocking of the ink cartridge 1. This design is ingenious and practical, fully utilizes the physical principle, and improves the overall performance of the device.

[0077] The ink cartridge 1 of this embodiment can be the first ink cartridge 10 in the previous embodiments or other ink cartridges 1, which has strong universality. This design can adapt to different types and specifications of ink cartridges 1, meet diversified market demands, and improve the market competitiveness of the product. The limiting cover 14 and the ink cartridge body 11 are detachably connected, which facilitates the inspection, repair and replacement of internal components such as the locking rod 13. At the same time, the rebound device and the sliding groove 211 and other structures are relatively simple, easy to clean and maintain, which reduces the maintenance cost and difficulty of the equipment and prolongs the service life of the equipment.

[0078] In one example embodiment, referring to FIGS. 1-4, Figure 2 and Figures 8 to 10 An ink cartridge 1, an ink cartridge seat 2 and an ink cartridge assembly are provided. It should be noted that in the ink cartridge, some ink (such as white ink) will precipitate in the ink cartridge, affecting the normal use of the ink cartridge. In the related art, an agitator motor is generally added on the ink cartridge, and the motor is connected with an agitator blade to realize rotation, thereby agitating the precipitated ink uniformly. However, this scheme wastes an agitator motor every time the ink cartridge is replaced, and the cost is high.

[0079] Based on this, in this embodiment, the ink cartridge assembly can further include a driving mechanism 31 and a driven member 32. The driving mechanism 31 is mounted to the ink cartridge seat 2, and the driven member 32 is mounted in the first ink cartridge 10 of the at least one ink cartridge 1. The first ink cartridge 10 can be used to contain ink that needs to be stirred. For example, white ink can generally precipitate, and the first ink cartridge 10 can be used to contain white ink.

[0080] In a state where the first ink cartridge 10 is mounted to the ink cartridge seat 2, the driving mechanism 31 is used to drive the driven member 32 to move, so as to stir the ink in the first ink cartridge 10. It should be noted that when the driving mechanism 31 drives the driven member 32 to move, the driven member 32 can rotate or can move irregularly, and this is not limited, as long as the movement of the driven member 32 can achieve the stirring effect of the ink in the first ink cartridge 10.

[0081] In this embodiment, when the first ink cartridge 10 is used to contain ink that can precipitate (such as white ink), the movement of the driven member 32 driven by the above-mentioned driving mechanism 31 can be used to achieve the stirring of the ink in the first ink cartridge 10, and when the first ink cartridge 10 needs to be replaced, since the driving mechanism 31 is arranged on the ink cartridge seat 2, and the first ink cartridge 10 is not provided with the driving mechanism 31 but only with the driven member 32, therefore the driving mechanism 31 can be reused without being replaced, thereby reducing the cost of replacing the first ink cartridge 10 and improving the user experience.

[0082] In one example embodiment, an ink cartridge 1, an ink cartridge seat 2, and an ink cartridge assembly are provided. In this embodiment, the driven member 32 can include a first magnetic member (such as a magnet), which is rotatably connected to the first ink cartridge 10, so as to ensure that the first magnetic member can rotate relative to the first ink cartridge 10 under the drive of the driving mechanism 31. The first magnetic member can be configured as a columnar structure, and the two ends of the columnar structure are arc surfaces, for example, the two ends of the columnar structure can be hemispheres. In this way, the stirring effect can be achieved while avoiding splashing of the ink.

[0083] The driving mechanism 31 can include a second magnetic member 313 (such as a magnet), and the driving mechanism 31 can drive the first magnetic member to rotate relative to the first ink cartridge 10 through the magnetic action between the second magnetic member 313 and the first magnetic member, so as to stir the ink in the first ink cartridge 10.

[0084] The driving mechanism 31 can include a driving motor 311 and a mounting member 312 fixedly connected with a motor shaft of the driving motor 311. For example, the motor shaft can be inserted into the mounting member 312 to achieve the fixed connection with the mounting member 312. In addition, a second magnetic member 313 can be mounted on the mounting member 312. The mounting member 312 can be provided with a mounting groove, and the second magnetic member 313 can be fixedly mounted in the mounting groove. For example, the second magnetic member 313 can be in interference fit with the mounting groove to achieve the fastening connection therebetween. For another example, the second magnetic member 313 can be in adhesive connection with the groove bottom of the mounting groove to achieve the fixed connection therebetween. Of course, the second magnetic member 313 can also be fixedly mounted on the mounting member 312 in other manners, which are not limited.

[0085] For example, the driving motor 311 can be a small DC motor. According to the size of the ink cartridge 1 and the viscosity of the ink, the power and the rotating speed of the motor can be selected to ensure that the driving motor 311 can provide appropriate stirring power. The mounting member 312 can be made of high-strength plastic material, such as polyoxymethylene (POM), by injection molding process, and has an elliptical disc shape for facilitating the connection with the motor shaft and the second magnetic member 313. The mounting member 312 is provided with a mounting hole matched with the motor shaft, and is fixedly connected with the motor shaft by interference fit or key connection to ensure that the mounting member 312 can stably rotate synchronously when the driving motor 311 rotates. The second magnetic member 313 can be a neodymium-iron-boron permanent magnet, which can have an elliptical plate shape. The second magnetic member 313 is fixedly mounted on the mounting member 312 by glue or screws to ensure that it will not fall off during rotation.

[0086] The driving motor 311 can be selected according to the size of the ink cartridge 1 and the viscosity of the ink to have appropriate power and rotating speed, so as to provide appropriate power for ink stirring. For large-capacity ink cartridges 1 or ink with high viscosity, a motor with large power and high rotating speed can be selected to ensure that the ink can be fully stirred. For small-capacity ink cartridges 1 or ink with low viscosity, a motor with small power and low rotating speed can be selected to ensure the stirring effect while reducing energy consumption.

[0087] It should be noted that the driving mechanism 31 can be a manual driving mechanism 31, and can also be an electric driving mechanism 31, which is not limited. For example, the driving mechanism 31 can adopt a manual crank and gear transmission structure. The manual crank is connected to the ink cartridge seat 2 through a rotating shaft, and a driving gear is installed on the rotating shaft of the crank. A driven gear is arranged inside the ink cartridge seat 2 and engaged with the driving gear, and the shaft of the driven gear can fix the second magnetic member 313. When the user rotates the manual crank, the driving gear drives the driven gear to rotate, and in turn drives the second magnetic member 313 to rotate. The second magnetic member 313 outside the first ink cartridge 10 and the first magnetic member inside the first ink cartridge 10 have a magnetic interaction, so that the first magnetic member can be driven to rotate relative to the first ink cartridge 10 to stir the ink in the first ink cartridge 10.

[0088] Among them, the driving mechanism 31 can adopt an electric driving motor 311 mode, and can also adopt a manual crank and gear transmission structure. The electric driving mode is convenient to operate and can realize automatic stirring, which is suitable for frequent use scenes; the manual driving mode has flexibility and autonomy, and when there is no power supply or temporary stirring is needed, the user can realize ink stirring by rotating the manual crank, which meets the use needs of different users in different scenes.

[0089] In addition, when the driving mechanism 31 includes the driving motor 311, the driving motor 311 can be installed on the ink cartridge seat, and the second magnetic member 313 and the first magnetic member generate interaction force to enable the magnetic interaction between the second magnetic member 313 and the first magnetic member to drive the first magnetic member to rotate.

[0090] Among them, the ink cartridge seat 2 can include a positioning mounting plate 22 for mounting the driving motor 311, and at least one positioning hole 221 is arranged on the positioning mounting plate 22, and the driving motor 311 is positioned and mounted on the positioning mounting plate 22 through the at least one positioning hole 221. For example, four positioning holes 221 can be arranged on the positioning mounting plate 22, and a fastener such as a screw or a bolt can be inserted into the positioning hole 221 to realize the positioning and mounting of the driving motor 311 on the positioning mounting plate 22. Of course, the driving motor 311 can also be mounted on the ink cartridge seat 2 in other ways, which is not limited.

[0091] Among them, the first ink cartridge 10 can include an ink cartridge body 11 and a mounting column 101 connected to the ink cartridge body 11. The first magnetic member can be a neodymium iron boron permanent magnet, for example. The first magnetic member is sleeved on the mounting column 101, and the first magnetic member can rotate relative to the mounting column 101. For example, the first magnetic member can include a mounting hole with a hole diameter larger than the diameter of the mounting column 101, so as to ensure that the first magnetic member can rotate relative to the mounting column 101.

[0092] Additionally, the first ink cartridge 10 may also include a limiting structure 102, which is disposed at the free end of the mounting post 101 to restrict the first magnetic component from detaching from the mounting post 101, thus preventing the first magnetic component from falling off the mounting post 101 when rotating. Along the radial direction of the mounting post 101, the size of the limiting structure 102 is larger than the diameter of the mounting hole in the first magnetic component, thereby limiting the first magnetic component. It should be noted that the axial end of the mounting post 101 connected to the ink cartridge body 11 is referred to as the fixed end, and the other axial end of the mounting post 101 is referred to as the free end. The limiting structure 102 can be a limiting piece, a limiting block, or a limiting ring, etc., and is not limited thereto. The limiting structure 102 may be made of plastic and can be fixed to the free end of the mounting post 101 by means of threaded connection or snap-fit ​​connection.

[0093] It should be noted that in this embodiment, after the first ink cartridge 10 is installed in the ink cartridge holder 2, the second magnetic component 313 corresponds to the first magnetic component in position, and the distance between them can be maintained within a preset distance range to ensure that the magnetic interaction between the second magnetic component 313 and the first magnetic component can drive the first magnetic component to rotate. The aforementioned preset distance range can be determined based on the magnetic strength of the first and second magnetic components 313, and its specific value can be set according to actual needs.

[0094] In this embodiment, the use of magnetic drive avoids the complex transmission structure and frequent component wear of traditional mechanical stirring methods, reducing manufacturing and maintenance costs. Simultaneously, some components of the drive mechanism 31 (such as the drive motor 311) can be reused, further reducing long-term operating costs. For example, when the first ink cartridge 10 needs to be replaced, the drive mechanism 31 can still be used, improving resource utilization and reducing the cost of replacing the ink cartridge 1.

[0095] In one exemplary embodiment, reference Figure 11 and Figure 12 As shown, an ink cartridge 1, an ink cartridge holder 2, and an ink cartridge assembly are provided. In this embodiment, in the corresponding mounting positions 21 and ink cartridge 1, the mounting position 21 is provided with a foolproof part 213, and the ink cartridge 1 is provided with a mating part 15 that cooperates with the foolproof part 213. The cooperation between the foolproof part 213 and the mating part 15 ensures foolproof installation of the ink cartridge 1 and the mounting position 21. Furthermore, in at least one mounting position 21 of the ink cartridge holder 2, the structure of the foolproof part 213 is different for different mounting positions 21. That is, each mounting position 21 can only be used to install the ink cartridge 1 to which the mating part 15 that cooperates with the foolproof part 213 of this mounting position 21 belongs. Based on this, it can be ensured that each ink cartridge 1 is accurately installed in the corresponding mounting position 21.

[0096] Among the mutually matched fool-proof parts 213 and the matching parts 15, one of the fool-proof parts 213 and the matching parts 15 comprises the fool-proof protrusion 131, and the other of the fool-proof parts 213 and the matching parts 15 comprises the fool-proof slot or the fool-proof hole matched with the fool-proof protrusion 131. For example, the fool-proof parts 213 can comprise the fool-proof protrusion 131, and the matching parts 15 can comprise the fool-proof slot, and the fool-proof protrusion 131 is inserted into the fool-proof slot to realize the fool-proof installation of the ink cartridge 1. For another example, the fool-proof parts 213 can comprise the fool-proof hole, and the matching parts 15 can comprise the fool-proof protrusion 131, and the fool-proof protrusion 131 is matched with the fool-proof hole to realize the fool-proof installation of the ink cartridge 1.

[0097] It should be noted that the fool-proof parts 213 and the matching parts 15 can be other structures besides the above structure, and the structures are not limited as long as the fool-proof installation of the ink cartridge 1 can be realized.

[0098] In addition, the ink cartridge 1 in the related art generally does not set the fool-proof structure, and the consumer is easy to insert the ink cartridges 1 of different colors (the ink cartridges 1 of different colors are used to contain the ink of different colors) when replacing the ink cartridge 1. In the embodiment, the different installation positions 21 on the ink cartridge seat 2 can be used to install the ink cartridges 1 of different colors. The ink cartridges 1 of different colors are used to contain the ink of different colors. By setting the fool-proof parts 213 on the installation positions 21 and the matching parts 15 on the ink cartridge 1, the correct installation of the ink cartridge 1 can be well ensured, and the color of the ink can be ensured to be correct.
