[0002] The ink cartridge is a component in the printer used to store ink. When the ink cartridge is installed in the mounting part of the printer, the ink outlet of the ink cartridge connects to the ink supply pin on the mounting part to supply ink to the printer. When printing, the ink cartridge cooperates with the inkjet printing device to supply ink to the print head of the printing device, and the printed result is imaged on the paper to achieve printing.

[0003] Usually, the ink outlet of the ink cartridge is blocked in the side cavity of the ink cartridge. In some schemes, the ink outlet is made visible by cooperating with the matching structure of the ink cartridge and the matching structure in the mounting portion. The ink cartridge is provided with a front cover that can be moved up and down, and the matching structure of the ink cartridge is provided on the front cover. However, in this case, since the front cover is movable, the matching structure of the ink cartridge and the matching structure in the mounting portion may be mismatched, resulting in difficulty in accurately docking the ink outlet of the ink cartridge and the ink supply needle on the mounting portion, affecting the normal ink replenishment of the printer.

[0004] Therefore, it is urgent to solve the technical problem that when the ink cartridge is installed in the installation part of the printer, the ink outlet hole of the ink cartridge is difficult to accurately connect with the ink supply needle in the printer. Utility Model Content

[0051] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0052] In the related art, a front cover that can move up and down is movably provided on the front surface of the ink cartridge. When the ink cartridge is installed in the installation cavity of the printer, the front cover moves up and down to remove the blocking effect of the moving part on the ink outlet. However, since the front cover moves up and down, it is difficult to ensure the position of the front cover and the matching structure in the installation part, which makes it difficult to accurately connect the ink outlet of the ink cartridge and the ink supply needle on the installation part, affecting the normal ink replenishment of the printer.

[0053] In view of this, the utility model provides an ink cartridge, which is equipped with a driving component. During the process of installing the ink cartridge in the installation cavity along the first direction, the driving component interacts with the moving part in the installation cavity, so that the position of the driving component moves upward from the first position to the second position. The driving component drives the moving part to move along the second direction, so that the moving part is disengaged from the abutment against the blocking part, and the blocking part no longer blocks the cooperation between the ink supply needle and the ink cartridge, thereby realizing the precise docking of the ink supply needle and the ink outlet.

[0054] The ink cartridge provided by the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0055] In order to better illustrate the ink cartridge provided by this application, refer to Figure 1 As shown, a coordinate system is established: wherein the length direction of the ink cartridge is the X-axis direction, the width direction of the ink cartridge is the Y-axis direction, and the height direction of the ink cartridge is the Z-axis direction, wherein the X-axis, Y-axis, and Z-axis are perpendicular to each other, or the X-axis, Y-axis, and Z-axis are nearly perpendicular to each other. The installation direction of the ink cartridge is along the length direction of the ink cartridge.

[0056] In this example, the first direction refers to the length direction of the ink cartridge, that is, the X-axis direction; the second direction refers to the height direction of the ink cartridge, that is, the Z-axis direction.

[0057] refer to Figure 2 and Figure 3 As shown, the present invention provides an ink cartridge, comprising: a cartridge body 20 and a drive assembly, wherein the cartridge body 20 has a front surface 21 and an ink outlet 23 arranged on the front surface 21 , and the cartridge body 20 has an accommodating cavity 22 inside, and the ink outlet 23 is connected to the accommodating cavity 22 .

[0058] The utility model provides an ink cartridge, which can be detachably installed in an installation cavity 11 of a printer along a first direction. An ink supply needle 12, a blocking member 13 and a movable member 14 are provided in the installation cavity 11. The ink supply needle 12 extends toward the ink cartridge along the first direction. The blocking member 13 is used to block the cooperation between the ink supply needle 12 and the ink cartridge. The movable member 14 is used to limit the movement of the blocking member 13.

[0059] In one possible implementation, reference Figure 3 As shown, the blocking member 13 is movably arranged along the first direction, that is, the X-axis direction, and the moving member 14 is movably arranged along the second direction, that is, the Z-axis direction. The moving member 14 has an opening 142 facing the ink cartridge. Figure 3 As shown, the movable member 14 is used to limit the movement of the blocking member 13 when it abuts against the blocking member 13, so that the blocking member 13 blocks the cooperation between the ink supply needle 12 and the ink cartridge, and the movable member 14 is used to stop limiting the movement of the blocking member 13 when it is out of abutment with the blocking member 13, so that the blocking member 13 releases the blocking of the ink supply needle 12 from cooperating with the ink cartridge.

[0060] In one possible implementation, reference Figure 1 and Figure 2 As shown, the printer includes a mounting portion 10, a mounting cavity 11 is formed in the mounting portion 10, and along a first direction, the mounting cavity 11 has a mounting opening 111 for the ink cartridge to enter, and a front sealing plate 101 is provided at the other end of the mounting portion 10, and the ink supply needle 12 is fixedly arranged relative to the front sealing plate 101 of the mounting portion 10.

[0061] In one possible implementation, the number of mounting cavities 11 in the mounting portion 10 can be one. Of course, the number of mounting cavities 11 in the mounting portion 10 can also be four. The four mounting cavities 11 are used to install ink cartridges storing four different colors of ink, for example, red, yellow, cyan and black, to achieve color printing.

[0062] The front sealing plate 101 of the mounting portion 10 has a through hole for the ink supply needle 12 to pass through. The ink supply needle 12 extends into the mounting cavity 11 through the through hole. The ink supply needle 12 is a hollow structure. The ink supply needle 12 has a channel for ink to pass through. The end of the ink supply needle 12 extending into the mounting cavity 11 is an ink inlet end 121. Figure 6 As shown, the ink inlet end 121 is used to connect with the ink outlet 23 to form a channel for fluid circulation at the connection position between the ink outlet 23 and the ink supply needle 12.

[0063] In one possible implementation, reference Figure 4 As shown, when the moving member 14 moves upward in the second direction, the moving member 14 no longer restricts the movement of the blocking member 13 in the first direction, so that the blocking member 13 can slide on the inner bottom wall of the installation cavity 11 along the first direction.

[0064] In one possible implementation, a baffle portion 16 is provided on the inner bottom wall of the installation cavity 11, and an elastic puller 15 is provided between the baffle portion 16 and the blocking member 13. One end of the elastic puller 15 is fixedly connected to the baffle portion 16, and the other end of the elastic puller 15 is fixedly connected to the blocking member 13. The elastic puller 15 is used to pull the blocking member 13 toward the baffle portion 16. When the ink cartridge is not installed in the printer's installation cavity 11, the blocking member 13 is further away from the front sealing plate 101 relative to the ink inlet end 121, thereby blocking the ink supply needle 12 from mating with the ink cartridge. The elastic puller 15 may be, for example, a spring.

[0065] In one possible implementation, reference Figure 4 and Figure 5 As shown, the blocking member 13 includes a bottom plate 131 and a vertical plate 132. The bottom plate 131 is slidably arranged on the inner bottom wall of the installation cavity 11 along the first direction. The bottom of the vertical plate 132 is fixedly connected to the bottom plate 131. An avoidance hole 1321 is opened in the vertical plate 132. When the blocking member 13 slides along the first direction, the ink supply needle 12 can pass through the avoidance hole 1321.

[0066] In a possible implementation method not shown in the figure, in order to achieve the smooth sliding setting of the blocking member 13 along the first direction, a sliding groove is set on the inner bottom wall of the installation cavity 11, and the sliding groove extends along the first direction. The bottom of the bottom plate 131 is fixedly connected to the slider, and the slider is slidably set in the sliding groove, thereby achieving the smooth sliding setting of the blocking member 13 on the inner bottom wall of the installation cavity 11.

[0067] refer to Figure 2 and Figure 4 As shown, the inner wall of the mounting cavity 11 is further provided with a support plate 17, which is used to support the ink supply needle 12 and guide the movement of the movable member 14 along the second direction. The bottom plate 131 of the blocking member 13 can pass through the bottom of the support plate 17. A through groove 171 is provided in the support plate 17, and the through groove 171 extends along the second direction. The movable member 14 has a guide protrusion 144 extending into the through groove 171, and the guide protrusion 144 moves in the through groove 171, thereby guiding the movement of the movable member 14 along the second direction.

[0068] In one possible implementation, reference Figure 4 As shown, for ink cartridges storing developers of different colors, the positions of the through slots 171 opened in the support plate 17 may be different. For example, the through slots 171 corresponding to ink cartridges of different colors may be located at different positions in the width direction of the ink cartridge to distinguish the colors of the ink cartridges and avoid installing ink cartridges of the wrong color into the installation cavity 11.

[0069] In a possible implementation, a surface of the guide protrusion 144 facing the box body 20 is an inclined surface, which has a good guiding effect and ensures that the moving member 14 moves along the second direction under the action of the moving assembly.

[0070] In one possible implementation, reference Figure 3 and Figure 5 As shown, the movable member 14 includes a movable body 141 and a leg 143 connected to the bottom end of the movable body 141. The opening 142 can be formed in the movable body 141. The leg 143 extends along the second direction. The leg 143 is used to abut against the end of the blocking member 13 away from the mounting port 111. In this example, the leg 143 is used to abut against the bottom plate 131 of the blocking member 13, thereby limiting the overall movement of the blocking member 13 along the first direction, so that the ink inlet end 121 of the ink supply needle 12 will not be exposed on the outside of the vertical plate 132, so that the blocking member 13 hinders the docking of the ink supply needle 12 with the ink outlet 23.

[0071] The utility model provides an ink cartridge, which, when the ink cartridge is not installed in the installation cavity 11 of the printer, the leg 143 of the movable member 14 abuts against the end of the blocking member 13 away from the installation opening 111. Under the blocking action of the movable member 14 on the blocking member 13, the blocking member 13 cannot move away from the installation opening 111 along the first direction, thereby achieving the blocking member 13 blocking the cooperation between the ink supply needle 12 and the ink cartridge. When the ink cartridge is installed into the installation cavity 11 of the printer from the installation port 111 along the first direction, the driving component moves synchronously with the ink cartridge along the first direction. When the driving component abuts against the moving part 14, part of the structure of the driving component moves upward and interacts with the moving part 14, so that the driving component drives the moving part 14 to move up in the second direction, and the restrictive effect of the moving part 14 on the blocking part 13 is released. At the same time, the ink cartridge abuts against the blocking part 13 and pushes the blocking part 13 to move along the first direction toward the installation cavity 11. The elastic pulling member 15 extends, and the ink inlet end 121 of the ink supply needle 12 is exposed, thereby unblocking the cooperation between the ink supply needle 12 and the ink cartridge.

[0072] The utility model provides an ink cartridge, which is provided with a driving assembly, at least part of which extends out from the front side of the front surface 21. During the process of the ink cartridge being installed in the installation cavity 11 along the first direction, the driving assembly interacts with the moving member 14, so that the position of the driving assembly changes, and the driving assembly moves upward from the first position to the second position. The driving assembly drives the moving member 14 to move along the second direction, so that the moving member 14 is disengaged from the abutment against the blocking member 13, and the blocking member 13 no longer blocks the cooperation between the ink supply needle 12 and the ink cartridge, thereby achieving precise docking of the ink supply needle 12 and the ink outlet 23.

[0073] In the second direction, ie, the Z-axis direction, since the second position is higher than the first position, when the driving assembly moves upward from the first position to the second position, the moving member 14 is also driven to move upward in the second direction.

[0074] In one possible implementation, reference Figure 3 and Figure 5 As shown, the cartridge body 20 is generally cubical in shape. When installed, the side of the cartridge body 20 facing the front cover 101 is a front surface 21. The top of the cartridge body 20 has an upper surface 24. In the second direction, the drive assembly is positioned between the ink outlet 23 and the upper surface 24, with the second position being higher than the first position and the first position being lower than the top of the movable member 14. This ensures that the drive assembly and movable member 14 are in proper contact during cartridge installation and prevents interference between the drive assembly and movable member 14 in the second direction, thereby preventing any impact on cartridge installation.

[0075] In a possible implementation, the guide protrusion 144 is located at the top of the moving member 14 , and the first position is lower than the guide protrusion 144 of the moving member 14 .

[0076] refer to Figure 3 and Figure 5 As shown, the upper surface 24 of the cartridge body 20 is provided with a snap-fit ​​portion 40. The rearward-facing surface of the snap-fit ​​portion 40 is a locking surface 41. When the cartridge body 20 is assembled in the printer's mounting portion 10, the locking surface 41 is a surface that faces rearward and contacts the locking structure within the mounting cavity 11. This rearward contact of the locking surface 41 with the locking structure within the mounting cavity 11 maintains the ink cartridge's stable installation within the mounting cavity 11. The rearward direction refers to the -X-axis direction.

[0077] The top of the engaging portion 40 has a horizontal surface 43 and an inclined surface 44 connected in sequence, with the horizontal surface 43 connected between the locking surface 41 and the inclined surface 44. Due to the inclined surface 44 and the horizontal surface 43, when the box body 20 is installed in the installation cavity 11, the locking structure in the installation cavity 11 abuts against the inclined surface 44 and the horizontal surface 43 while being smoothly guided to a position behind the locking surface 41.

[0078] The upper surface 24 of the housing 20 is also provided with an operating portion 50. A user presses the operating portion 50 to disengage the locking surface 41 from the locking structure within the mounting cavity 11. The upward and rearward facing surface of the operating portion 50 is the operating surface 51. The operating surface 51 has anti-slip grooves, making it easier for the user to identify the operating surface 51 and preventing the user's fingers from slipping.

[0079] A detected component 60 is also located within the chamber 22 of the cartridge body 20. This component includes a float 61, whose specific gravity is lower than that of the ink stored within the chamber 22. Therefore, within the chamber 22, the ink exerts a buoyant force on the float 61, causing it to float on the ink. A decrease in the amount of ink within the chamber 22 affects the movement of the float, which in turn affects the movement of the detected component 60. This movement of the detected component 60 affects the intensity of light received by the light-receiving portion of the remaining ink level sensor within the chamber, thereby achieving ink level detection.

[0080] A light shielding plate 62 is provided on the upper surface 24 of the box body 20. The light shielding plate 62 is located between the light-emitting part and the light-receiving part of the assembly sensor. When the ink cartridge is installed, the light shielding plate 62 blocks the light signal of the installation sensor of the box installation part. Thus, the printer can recognize that an ink cartridge is installed in the installation cavity 11.

[0081] Example 1

[0082] refer to Figure 3 、 Figure 4 and Figure 5 As shown, in the first embodiment, the driving component is a first driving component 31, and the first driving component 31 includes a driving rod 311 and a first deformation portion 312. The first end of the driving rod 311 is connected to the front surface 21 through the first deformation portion 312, and the second end of the driving rod 311 extends obliquely toward the direction close to the upper surface 24 and away from the front surface. The second end of the driving rod 311 is used to abut against the inner wall surface of the moving part. For example, the second end of the driving rod 311 can be abutted against the inner wall surface of the opening cavity 142.

[0083] During the process of installing the ink cartridge in the installation cavity 11, the angle between the extension direction of the driving rod 311 and the front surface 21 gradually decreases, and the second end of the driving rod 311 is displaced in the up and down directions. The second end of the driving rod 311 drives the moving part 14 to move upward, so that the moving part 14 is disengaged from the blocking part 13.

[0084] The present utility model provides an ink cartridge, which, during the process of installing the ink cartridge into the installation cavity 11 of the printer along the first direction, the cartridge body 20 brings the first driving component 31 close to the moving part 14 along the first direction, and simultaneously due to the mutual abutment between the first driving component 31 and the moving part 14, the first driving component 31 moves from the first position to the second position, and the angle between the extension direction of the driving rod 311 and the front surface 21 gradually decreases, and the first driving component 31 drives the moving part 14 to move along the second direction, so that the moving part 14 is disengaged from the abutment against the blocking part 13, and the movement of the blocking part 13 along the first direction is no longer restricted by the moving part 14, and after the cartridge body 20 contacts the blocking part 13 along the first direction, it also pushes the blocking part 13 to move along the first direction, so that the blocking part 13 releases the blocking cooperation between the ink supply needle 12 and the ink cartridge, and facilitates the insertion of the ink supply needle 12 into the ink outlet 23 for docking.

[0085] In a possible implementation, the driving rod 311 may be in the shape of an inclined straight line or an inclined wavy line.

[0086] In one possible implementation, the first deformation portion 312 is arc-segment shaped, and the center of the first deformation portion 312 is located on the side of the first deformation portion 312 close to the upper surface 24 of the box body 20 , which helps to improve the elastic deformation effect of the first deformation portion 312 .

[0087] In a possible implementation, the angle between the extension direction of the driving rod 311 and the front surface 21 is an acute angle.

[0088] Since the second end of the driving rod 311 extends obliquely at the front side of the front surface 21 and toward the upper surface 24, it is convenient for the box body 20 to bring the first driving assembly 31 close to the moving member 14 along the first direction, and the second end of the driving rod 311 extends into the moving member 14 and abuts against the inner wall surface of the moving member 14. In this example, the second end of the driving rod 311 extends into the open cavity 142 and abuts against the inner wall surface of the open cavity 142. As the box body 20 brings the first driving assembly 31 close to the moving member 14 along the first direction, the angle between the extending direction of the driving rod 311 and the front surface 21 gradually decreases, and the position of the second end of the driving rod 311 becomes higher, thereby achieving the movement of the moving member 14 along the second direction.

[0089] In one possible implementation, reference Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, the first driving assembly 31 further includes a second deformation portion 313 , and the second deformation portion 313 is connected between the first end of the driving rod 311 and the front surface 21 .

[0090] In this embodiment, the second deformation portion 313 is connected between the first end of the driving rod 311 and the front surface 21 to increase the elasticity of the first driving component 31, reduce the problem of the first driving component 31 getting stuck during the rotational movement, and improve the service life of the first driving component 31.

[0091] The second deformation portion 313 is arc-shaped, which improves the elastic deformation effect of the first deformation portion 312. The center of the second deformation portion 313 is located on the side of the second deformation portion 313 facing away from the first deformation portion 312.

[0092] In one possible implementation, the connection position between the front surface 21 and the first deformation portion 312 is the first connection point, and the connection position between the front surface 21 and the second deformation portion 313 is the second connection point. Along the second direction, the first connection point and the second connection point are arranged at intervals from each other, and a deformation cavity 314 is formed between the second deformation portion 313 and the first deformation portion 312, so that the existence of the second deformation portion 313 will not affect the displacement of the first drive component 31, and the second deformation portion 313 has a certain pulling effect on the drive rod 311, which can improve the connection strength between the first drive component 31 and the front surface 21.

[0093] The utility model provides an ink cartridge, when the ink cartridge is installed into the installation cavity 11 of the printer from the installation port 111 along the first direction, the first driving component 31 moves synchronously with the ink cartridge along the first direction, when the first driving component 31 abuts against the moving part 14, the driving rod 311 interacts with the moving part 14, the angle between the extension direction of the driving rod 311 and the front surface 21 gradually decreases, the first driving component 31 drives the moving part 14 to move up along the second direction, so that the moving part 14 is disengaged from the abutment against the blocking part 13, and the movement of the blocking part 13 along the first direction is no longer restricted by the moving part 14, and at the same time, as the ink cartridge enters the installation cavity 11 of the printer from the installation port 111 along the first direction, the ink cartridge pushes the blocking part 13 to move along the first direction, and the blocking part 13 leaves the position of the ink inlet end 121 of the ink supply needle 12, thereby releasing the blocking of the ink supply needle 12 from cooperating with the ink cartridge.

[0094] Example 2

[0095] In the second embodiment, the driving component is a second driving component 32, and the second driving component 32 includes: a first mating part 321 and a second mating part 322. The first mating part 321 is movably arranged on the box body 20 along the first direction, and the end of the first mating part 321 away from the front surface 21 has a protrusion 323, and the second mating part 322, a part of the second mating part 322 abuts against the protrusion 323. During the process of installing the ink cartridge in the installation cavity 11, the second mating part 322 is pressed by the protrusion 323, deformed in the direction away from the first mating part 321, and drives the moving part 14 to move along the second direction, so that the moving part 14 is disengaged from the abutment against the blocking part 13.

[0096] In one possible implementation, reference Figure 10 、 Figure 11 and Figure 12 As shown, the box body 20 also has a fixed cavity 25 inside, and the fixed cavity 25 and the accommodating cavity 22 are arranged at intervals from each other. The front surface 21 constitutes the front wall of the fixed cavity 25. A through hole 211 communicating with the fixed cavity 25 is opened in the front surface 21. The driving component is arranged in the fixed cavity 25 and extends to the front side of the front surface 21 through the through hole 211.

[0097] In one possible implementation, a partition 26 is provided inside the box body 20, which separates the fixed cavity 25 from the accommodating cavity 22 to prevent the ink stored in the accommodating cavity 22 from entering the fixed cavity 25, thereby preventing the problem of ink leakage.

[0098] In one possible implementation, the first mating member 321 is movably disposed in the fixed cavity 25 along a first direction, with a portion of the first mating member 321 extending beyond the front surface 21.

[0099] In one possible implementation, the second mating member 322 may also be a component that can move up and down relative to the cartridge body 20. When the ink cartridge is installed into the installation cavity 11 of the printer, the second mating member 322 is abutted by the first mating member 321, and the second mating member 322 moves up and down as a whole.

[0100] The first end of the second mating piece 322 is connected to the front surface 21, the second end of the second mating piece 322 abuts the protrusion 323, the second mating piece 322 is located on one side of the first mating piece 321 along the second direction, and the second end of the second mating piece 322 is configured to deform toward the side away from the first mating piece 321 during the process of the ink cartridge being installed in the installation cavity 11 and drive the moving piece 14 to move along the second direction, so that the moving piece 14 is disengaged from the abutment against the blocking piece 13.

[0101] In one possible implementation, the second fitting part 322 is elastic and can be an elastic sheet. When the second fitting part 322 is squeezed by the protrusion 323, the second fitting part 322 is displaced, thereby moving from the first position to the second position, thereby driving the moving part 14 to move up in the second direction.

[0102] In one possible implementation, reference Figure 10 、 Figure 11 and Figure 12 As shown, a limiting portion 326 is provided on the outer wall of the first fitting part 321. The limiting portion 326 can be connected to the two opposite side surfaces of the first fitting part 321 along the second direction. The limiting portion 326 is located in the fixed cavity 25. The limiting portion 326 can prevent the first fitting part 321 from completely falling out of the fixed cavity 25, thereby ensuring the stability of the first fitting part 321.

[0103] In a possible implementation, the second driving assembly 32 further includes a first elastic member 327 . Along the first direction, the first elastic member 327 is disposed between the inner wall of the fixing cavity 25 and the first matching member 321 .

[0104] To improve the installation stability of the first elastic member 327, a first protrusion 251 is provided on the inner wall of the fixing cavity 25. A second protrusion 3211 is provided on the end of the first fitting 321 away from the protrusion 323. The ends of the first elastic member 327 are respectively sleeved on the outer circumference of the first protrusion 251 and the outer circumference of the second protrusion 3211. This structure effectively prevents the first elastic member 327 from falling off and improves the fixing stability of the first elastic member 327.

[0105] In this example, along the first direction, there is a distance between the first protrusion 251 and the second protrusion 3211 .

[0106] In one possible implementation, a guide groove 324 is provided on the inner wall of the fixed cavity 25 and one of the first fitting parts 321, and a guide column 325 is provided on the inner wall of the fixed cavity 25 and the other of the first fitting parts 321.

[0108] In a possible implementation, a guide groove 324 is provided on a side wall of the first fitting member 321 , and a guide post 325 is provided on an inner wall of the fixing cavity 25 .

[0109] In another possible implementation, a guide groove 324 is provided on the inner wall of the fixing cavity 25 , and a guide post 325 is provided on the first fitting member 321 .

[0110] The utility model provides an ink cartridge. When the ink cartridge is installed in the installation cavity 11 of the printer from the installation port 111 along the first direction, the second drive component 32 moves synchronously with the ink cartridge along the first direction. When the second drive component 32 abuts against the moving part 14, the first matching part 321 is squeezed and displaced, and retreats into the fixed cavity 25. The protrusion 323 of the first matching part 321 squeezes the second matching part 322. The second matching part 322 is squeezed and deformed from the first position to the second position. Relative to the first position, the abutment of the second matching part 322 is close to the first position. One end of the protrusion 323 is at a higher height in the second position, so that the second mating member 322 drives the movable member 14 to move up in the second direction, and causes the movable member 14 to disengage from the blocking member 13. The movement of the blocking member 13 in the first direction is no longer restricted by the movable member 14. At the same time, as the ink cartridge enters the installation cavity 11 of the printer from the installation port 111 along the first direction, the ink cartridge pushes the blocking member 13 to move in the first direction, and the blocking member 13 leaves the ink inlet end 121 of the ink supply needle 12, thereby releasing the blocking of the ink supply needle 12 from the ink cartridge.

[0111] In one possible implementation, the fixed cavity 25 may pass through the box body 20 up and down, and the upper and lower ends of the fixed cavity 25 respectively pass through the upper surface 24 of the box body 20 and the bottom wall of the box body 20; of course, in other possible implementations, the fixed cavity 25 may also protrude from the front side of the box body 20, and the fixed cavity 25 is located on the upper side of the ink outlet 23; or, in other possible implementations, the fixed cavity 25 may not be provided in the box body 20, and the drive assembly is connected to the front surface 21 of the box body 20, and the drive assembly is exposed on the outside of the box body 20.
