Description

Technical Field

[0001] The invention relates to the technical field of inkjet printers, and in particular to an ink cartridge. Background Art

[0002] As an important component of an inkjet printer, the ink cartridge provides ink for the printer. The ink cartridge can be detachably installed in the installation part of the printer. Usually, an ink outlet is provided on the front surface of the ink cartridge. When the ink cartridge is installed in the printer, the ink supply needle in the printer connects to the ink outlet of the ink cartridge to supply the ink stored in the ink cartridge to the printer.

[0003] Usually, the ink outlet of the ink cartridge is blocked in the cavity of the ink cartridge. In some schemes, the ink outlet is visible by utilizing the matching structure of the ink cartridge to cooperate with 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 arranged on the front cover. However, in this case, since the front cover is movable, the matching structure of the ink cartridge may mismatch with the matching structure in the mounting portion, resulting in difficulty in accurately docking the ink outlet of the ink cartridge with the ink supply needle on the mounting portion, thereby affecting the normal ink replenishment of the printer.

[0004] Therefore, it is urgent to solve the technical problem that the ink outlet hole of the ink cartridge is difficult to accurately connect with the ink supply needle on the mounting part, which affects the normal ink filling of the printer. Summary of the invention

[0005] The present invention provides an ink cartridge, which is used to at least solve the technical problem that the ink outlet hole of the ink cartridge is difficult to accurately connect with the ink supply needle on the mounting part, thus affecting the normal ink filling of the printer.

[0006] In order to achieve the above object, the present invention provides an ink cartridge, which is detachably installed in a mounting cavity of a printer along a first direction, wherein an ink supply needle, a blocking member, and a moving member are arranged in the mounting cavity, wherein the blocking member is used to block the cooperation between the ink supply needle and the ink cartridge, and the moving member is used to limit the movement of the blocking member, and the ink cartridge comprises:

[0007] A box body, the box body comprising a box body, the box body having an interior with a receiving cavity for receiving ink, the box body having a front surface, the front surface being provided with an ink outlet (23) communicating with the receiving cavity, the box body also being provided with a guide member and an action member;

[0008] During the process of installing the ink cartridge into the installation cavity, the guiding member abuts against the blocking member and drives the acting member to move along the second direction, so that the acting member drives the moving member to move along the second direction from a position abutting against the blocking member to a position disengaged from the blocking member.

[0009] The present invention provides an ink cartridge, which is provided with a guide member. When the cartridge body moves along a first direction, the guide member drives the acting member to move along a second direction, so that the acting member drives the moving member to move along the second direction from a position resisting against a blocking member to a position disengaged from the blocking member. The blocking member is no longer resisted by the moving member, and the blocking member can leave the position that blocks the ink supply needle from cooperating with the ink cartridge. The ink supply needle is mated with the ink cartridge, avoiding the incorrect mating of the cover member and the moving member caused by the random movement of the cover member in the related technology, thereby improving the accuracy of the mating between the ink supply needle and the ink cartridge, which is helpful for normal ink replenishment of the printer.

[0010] In a possible implementation, the box body further includes a cover component, the cover component is movably arranged along the height direction of the box body, and the guide member and the action member are both connected to the cover member.

[0011] In one possible implementation, a side of the guide member facing the blocking member is a guide slope, and the guide slope is used to abut against the blocking member. Along the installation direction of the ink cartridge into the installation cavity, the guide slope is inclined toward the top end surface of the box body.

[0012] In a possible implementation, the actuating member includes a first actuating member, which protrudes from the bottom end of the cover member and extends obliquely from the front side of the cover member toward the top end surface of the box body.

[0013] In a possible implementation, the actuating member includes a second actuating member, the second actuating member extends to the front side of the cover component, and the second actuating member extends obliquely from the top end of the cover component toward a direction away from the top end surface of the box body.

[0014] In a possible implementation, the second acting member is an elastic member.

[0015] In one possible implementation, a hanging ring is formed at one end of the second acting member away from the cover member, and a guide protrusion is formed at one end of the movable member facing the box body. During the process of installing the ink cartridge in the installation cavity, the hanging ring is hooked on the side of the guide protrusion that is away from the top end surface of the box body.

[0016] In a possible implementation manner, an end of the second acting member that is away from the cover component is further away from the front surface than the guide member.

[0017] In a possible implementation, in the height direction of the box body, the action member is located on the upper side of the guide member, and the guide member is located on the upper side of the ink outlet.

[0018] In a possible implementation, in the height direction of the box body, the guide member and the action member are both lower than the top end surface of the box body.

[0019] The present invention provides an ink cartridge, in which a cover component, a guide component and an action component are located at the lowest position in the height direction of the ink cartridge, and during the process of installing the cartridge body into the installation cavity along a first direction, stable contact between the guide component and the blocking component is ensured, and contact positions between the action component and the moving component are ensured not to be misaligned, so that during the process of the guide component moving up along a second direction, the action component is driven to move up along the second direction, and the action component then drives the moving component to move up along the second direction, thereby unlocking the blocking component.

[0020] In addition to the technical problems solved by the embodiments of the present invention described above, the technical features that constitute the technical solutions, and the beneficial effects brought about by the technical features of the technical solutions, other technical problems that can be solved by an ink cartridge provided by an embodiment of the present invention, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further described in detail in the specific implementation methods.

[0044] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] In the related art, a movable front cover 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, and the front cover pushes the movable part to move, so as to release the blocking effect of the movable part on the ink outlet. However, since the front cover moves up and down, it is difficult to ensure the accuracy of the matching position of the front cover and the movable part, which makes it difficult to accurately connect the ink outlet hole of the ink cartridge and the ink supply needle on the installation part, affecting the normal ink replenishment of the printer.

[0046] In view of this, the present invention provides an ink cartridge, which, by setting a guide member, when the cartridge body moves along a first direction, the guide member drives the acting member to move along a second direction, so that the acting member drives the moving member to move along the second direction from a position resisting the blocking member to a position disengaged from the blocking member, and the blocking member is no longer resisted by the moving member. The blocking member can leave the position that blocks the ink supply needle from cooperating with the ink cartridge, and the ink supply needle is mated with the ink cartridge, thereby avoiding the problem in the related art that the accuracy of the mating between the ink supply needle and the ink cartridge is affected due to the incorrect mating of the cover member and the moving member.

[0047] The ink cartridge provided by the embodiment of the present invention is described below with reference to the accompanying drawings.

[0048] Embodiment 1

[0049] refer to Figure 1 As shown, in order to better illustrate the ink cartridge provided by the present application, 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, the Y-axis, and the Z-axis are perpendicular to each other, or the X-axis, the Y-axis, and the Z-axis are nearly perpendicular to each other. The installation direction of the ink cartridge is along the length direction of the ink cartridge.

[0050] In this example, the first direction refers to the length direction of the ink cartridge, that is, the X-axis direction.

[0051] refer to Figure 1 and Figure 2As shown, an ink cartridge provided by the present invention 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 arranged in the installation cavity 11, the blocking member 13 is movably arranged along the first direction, i.e., along the X-axis direction, and the movable member 14 is movably arranged along the second direction, the blocking member 13 is used to block the cooperation between the ink supply needle 12 and the ink cartridge, and the movable member 14 is used to limit the movement of the blocking member 13.

[0052] When the movable member 14 abuts against the blocking member 13, the blocking member 13 is locked in the position blocking the ink supply needle 12 from cooperating with the ink cartridge, that is, part of the blocking member 13 is located in the -X end direction of the ink supply needle 12, or the blocking member 13 and the -X end of the ink supply needle 12 are in the same plane. When the movable member 14 is disengaged from the abutment against the blocking member 13, the blocking member 13 is unlocked from the position blocking the ink supply needle 12 from cooperating with the ink cartridge, and the blocking member 13 can move along the X-axis direction.

[0053] It is easy to understand that the second direction is the moving direction of the moving member 14 to unlock the blocking member 13, and the second direction includes but is not limited to the Z-axis direction, and can also be any direction perpendicular to the X-axis, such as the Y-axis direction. In this example, the second direction takes the Z-axis direction as an example.

[0054] refer to Figure 5 and Figure 6 As shown, an ink cartridge provided by the present invention includes a box body 20, the box body 20 includes a box body 24, the box body 24 has a accommodating cavity 22 for accommodating ink, the box body 20 has a front surface 21, and the front surface 21 is provided with an ink outlet 23 connected to the accommodating cavity 22.

[0055] 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, along a first direction, i.e., the X-axis direction, one end of the mounting portion 10 is a mounting port 111 connected to the mounting cavity 11, the other end of the mounting portion 10 is a front sealing plate 101 of the mounting portion 10, and an ink supply needle 12 is fixedly arranged relative to the front sealing plate 101 of the mounting portion 10, and the extension direction of the ink supply needle 12 is along the first direction.

[0056] 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 respectively used to install ink cartridges storing four different colors of ink, for example, red, yellow, cyan and black, to achieve color printing.

[0057] refer to Figure 1 and Figure 3As shown, the front sealing plate 101 of the mounting portion 10 has a through hole for the ink supply needle 12 to pass through, and the ink supply needle 12 extends into the mounting cavity 11 through the through hole. The ink supply needle 12 is a hollow structure, and the ink supply needle 12 has a channel for ink to pass through. One end of the ink supply needle 12 extending into the mounting cavity 11 is an ink inlet end 121. Figure 2 and Figure 3 As shown, the ink inlet end 121 is used to dock 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 .

[0058] In one possible implementation, reference Figure 4 As shown, when the movable member 14 moves up along the second direction and disengages from the blocking member 13, the blocking member 13 is unlocked from the position blocking the ink supply needle 12 from cooperating with the ink cartridge, and the movable member 14 no longer restricts the movement of the blocking member 13 along 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, i.e., the X-axis direction, and the ink cartridge can be installed smoothly, preventing the occurrence of problems such as the inability to install the ink cartridge due to installation errors and other factors.

[0059] In a possible implementation, the inner bottom wall of the installation cavity 11 is provided with a baffle portion 16, and an elastic pulling member 15 is provided between the baffle portion 16 and the blocking member 13, one end of the elastic pulling member 15 is fixedly connected to the baffle portion 16, and the other end of the elastic pulling member 15 is fixedly connected to the blocking member 13, and the elastic pulling member 15 is used to pull the blocking member 13 to move close to the baffle portion 16, so that when the ink cartridge is not installed in the installation cavity 11 of the printer, the blocking member 13 blocks the ink inlet end 121 of the ink supply needle 12, and blocks the cooperation between the ink supply needle 12 and the ink cartridge. The elastic pulling member 15 can be, for example, a spring.

[0060] In one possible implementation, reference Figure 3 and Figure 4 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 mounting cavity 11 along a first direction, i.e., the X-axis 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.

[0061] In a possible implementation not shown in the figures, in order to achieve smooth sliding of the blocking member 13 along the first direction, a slide groove is set on the inner bottom wall of the installation cavity 11, and the slide groove extends along the first direction. The bottom of the bottom plate 131 is fixedly connected to a slider, and the slider is slidably set in the slide groove, thereby achieving smooth sliding of the blocking member 13 on the inner bottom wall of the installation cavity 11.

[0062] In one possible implementation, reference Figure 1 and Figure 4 As shown, the movable member 14 includes a movable body 141 and a leg 143 connected to the movable body 141 and connected to the bottom end of the movable body 141. The movable body 141 has an open cavity 142 on one side facing the ink cartridge. The leg 143 extends along the second direction. The leg 143 is used to abut against one end of the blocking member 13 that is away from the mounting port 111 of the mounting cavity 11. 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 extend out of the side of the vertical plate 132 facing the mounting port 111, thereby achieving the blocking member 13 blocking the ink supply needle 12 from docking with the ink outlet 23.

[0063] The present invention provides an ink cartridge. 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 one end of the blocking member 13 away from the installation opening 111 of the installation cavity 11. Under the resistance action of the movable member 14 on the blocking member 13, the blocking member 13 is locked in a position blocking the ink supply needle 12 from cooperating with the ink cartridge. The blocking member 13 cannot move away from the installation opening 111 along the first direction, thereby achieving the blocking member 13 blocking the ink supply needle 12 from cooperating with the ink cartridge.

[0064] refer to Figure 4 As shown, when the ink cartridge is installed into the installation cavity 11 of the printer from the installation port 111 along the first direction, the guide member 30 moves synchronously with the ink cartridge along the first direction, and when the action member 40 abuts against the moving member 14, the action member 40 interacts with the moving member 14, so that the moving member 14 moves up along the second direction, and the blocking member 13 is unlocked from the position blocking the ink supply needle 12 from cooperating with the ink cartridge. At the same time, the guide member 30 abuts against the blocking member 13 and pushes the blocking member 13 to move toward the installation cavity 11 along the first direction, and the elastic pulling member 15 is extended, and the blocking member 13 leaves the ink inlet end 121 of the ink supply needle 12, thereby achieving the release of the blocking of the ink supply needle 12 and the precise cooperation of the ink cartridge, which helps to improve the ink supply effect of the ink cartridge to the printer.

[0065] In one possible implementation, a support plate is further provided on the inner wall of the mounting cavity 11, and the support plate 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. A through groove is provided in the support plate, and the through groove extends along the height direction of the ink cartridge. Part of the movable member 14 extends into the through groove and moves in the through groove, thereby ensuring that the movable member 14 moves in the second direction through the guiding effect of the through groove on the movable member 14.

[0066] In one possible implementation, for ink cartridges storing developers of different colors, the positions of the through slots in the support plate may be different to distinguish the colors of the ink cartridges and avoid installing an ink cartridge of a wrong color into the installation cavity 11 .

[0067] refer to Figure 5 and Figure 6 As shown, the upper surface 26 of the cartridge body 20 is provided with a clamping portion 70. The surface of the clamping portion 70 facing rearward is a locking surface 71. When the cartridge body 20 is assembled to the mounting portion 10 of the printer, the locking surface 71 is a surface that can contact the locking structure in the mounting cavity toward the rear. The locking surface 71 contacts the locking structure in the mounting cavity 11 toward the rear, so that the ink cartridge is stably assembled in the mounting cavity 11. The rear is the -X axis direction.

[0068] The top of the engaging portion 70 has a horizontal surface 72 and an inclined surface 73 connected in sequence, and the horizontal surface 72 is connected between the locking surface 71 and the inclined surface 73. Through the inclined surface 73 and the horizontal surface 72, when the box body 20 is installed in the installation cavity 11, the locking structure in the installation cavity 11 is smoothly guided to the rear of the locking surface 71 while contacting the inclined surface 73 and the horizontal surface 72.

[0069] The upper surface 26 of the box body 20 is also provided with an operating portion 50. When a user presses the operating portion 50, the locking surface 71 can be disengaged from the locking structure in the installation cavity 11. The surface of the operating portion 50 facing upward and backward is the operating surface 51. The operating surface 51 has anti-slip patterns, which makes it easy for the user to identify the operating surface 51 and also has an anti-slip effect on the user's fingers.

[0070] A detected component 60 is also disposed in the accommodating chamber 22 of the box body 20. The detected component 60 includes a float 61. The specific gravity of the float 61 is smaller than the specific gravity of the ink stored in the accommodating chamber 22. Therefore, in the accommodating chamber 22, the ink generates buoyancy on the float 61, so that the float 61 floats on the ink. The reduction of the amount of ink in the accommodating chamber 22 affects the movement of the float, thereby affecting the movement of the detected component 60. The movement of the detected component 60 affects the intensity of light received by the light receiving part of the remaining amount sensor of the installation chamber, thereby achieving the purpose of ink amount detection.

[0071] A shading plate 62 is provided on the upper surface 26 of the box body 20, and the shading 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 shading plate 62 blocks the light signal of the installation sensor of the box installation part, thereby, the printer can recognize that an ink cartridge is installed in the installation cavity 11.

[0072] refer to Figure 1 and Figure 7 As shown, the present invention provides an ink cartridge, comprising: a box body 20, a guide member 30 and an action member 40, the box body 20 includes a box body 24, the box body 24 has a accommodating cavity 22 for accommodating ink, the box body 20 has a front surface 21, and the front surface 21 is provided with an ink outlet 23 connected to the accommodating cavity 22.

[0073] The guiding member 30 is arranged on the front surface 21, and is used to abut against the blocking member 13; the acting member 40 is arranged on the box body 20; the guiding member 30 is configured to drive the acting member 40 to move along the second direction when the box body 20 moves along the first direction, so that the acting member 40 drives the moving member 14 to move along the second direction from a position abutting against the blocking member 13 to a position disengaged from the blocking member 13.

[0074] The present invention provides an ink cartridge, which is provided with a guide member 30. When the cartridge body 20 moves along the first direction, the guide member 30 drives the acting member 40 to move along the second direction, so that the acting member 40 drives the moving member 14 to move along the second direction from a position resisting against the blocking member 13 to a position separated from the blocking member 13. The blocking member 13 is no longer resisted by the moving member 14, and the blocking member 13 can leave the position that blocks the ink supply needle 12 from cooperating with the ink cartridge. The ink supply needle 12 is mated with the ink cartridge, which avoids the wrong mating between the cover member and the moving member 14 caused by the random movement of the cover member in the related art, thereby avoiding affecting the accuracy of the mating between the ink supply needle 12 and the ink cartridge.

[0075] The second direction is the moving direction of the moving member 14 to unlock the blocking member 13, including but not limited to the direction along the Z axis.

[0076] In one possible implementation, the action member 40 is disposed on the box body 20, and the action member 40 may be disposed on the front surface 21 of the box body 20. When the ink cartridge is not installed in the installation cavity 11, the action member 40 may be hidden in the box body 20, that is, the action member 40 does not protrude from the front surface 21. When the ink cartridge is installed in the installation cavity 11, the action member 40 protrudes forward from the front surface 21.

[0077] In one possible implementation, reference Figure 2 , Figure 6 and Figure 7 As shown, the top surface of the box body 20 is the upper surface 26, and the box body 20 also includes a cover component 25, which is movably arranged on the front surface 21 along the height direction of the box body 20, and the cover component 25 is located between the ink outlet 23 and the upper surface 26, and the guide member 30 and the action member 40 are both connected to the cover component 25.

[0078] With such a structure, when the guide member 30 moves up in the second direction, the guide member 30 drives the action member 40 to move via the cover member 25. When the action member 40 moves up in the second direction, the action member 40 drives the movable member 14 to move up in the second direction, so that the action member 40 is disengaged from the abutment against the blocking member 13, and the blocking member 13 is unlocked from the position blocking the ink supply needle 12 from cooperating with the ink cartridge.

[0079] In other possible implementations, the guiding member 30 is directly connected to the actuating member 40 , and the guiding member 30 directly drives the actuating member 40 to move upward in the second direction.

[0080] In one possible implementation, reference Fig.13 As shown, the side of the guide member 30 facing the blocking member 13 is a guide slope 31, which is used to abut against the blocking member 13. Along the installation direction of the ink cartridge into the installation cavity 11, the guide slope 31 gradually tilts toward the direction close to the top surface of the cartridge body 20. That is, along the direction in which the ink cartridge is installed into the installation cavity 11, the guide slope 31 gradually tilts toward the direction close to the upper surface 26.

[0081] In one possible implementation, the guide member 30 is a triangular block structure. For example, the guide member 30 may be in the shape of a right triangle. One right-angled side of the guide member 30 is slidably disposed on the front surface 21 along the height direction of the box body 20, and the other right-angled side of the guide member 30 may be located at the bottom of the cover member 25. The guide slope 31 is the hypotenuse of the right triangle relative to the right angle, and the side of the guide member 30 facing the blocking member 13 is the guide slope 31.

[0082] In one possible implementation, reference Figure 7 As shown, a hollow hole 252 is defined in the cover member 25 , and a portion of the front surface 21 is exposed through the hollow hole 252 .

[0083] In one possible implementation, reference Figure 3 As shown, the box body 20 includes a limiting protrusion 27 arranged on the front surface 21, and the side of the cover part 25 facing the box body 24 is provided with a limiting groove 251, the limiting groove 251 extends along the Z-axis direction, and the limiting protrusion 27 moves in the limiting groove 251, thereby guiding the movement of the cover part 25 along the height direction of the ink cartridge, that is, the Z-axis direction.

[0084] In one possible implementation, there is a gap between the cover member 25 and the inner wall of the installation cavity 11, and there is a gap between the limiting protrusion 27 and the limiting groove 251, so that under the action of gravity, the cover member 25, the guide member 30 and the action member 40 are located at the lowest position along the height direction of the ink cartridge, i.e., the Z-axis direction. In the process of installing the box body 20 into the installation cavity 11 along the first direction, i.e., the X-axis direction, the stable contact between the guide member 30 and the blocking member 13 is ensured, and the contact position of the action member 40 and the moving member 14 is ensured not to be misaligned, so that in the process of the guide member 30 moving up in the second direction, the action member 40 is driven to move up in the second direction, and the action member 40 then drives the moving member 14 to move up in the second direction, thereby unlocking the blocking member 13.

[0085] In one possible implementation, reference Figure 2 , Figure 3 and Figure 4As shown, the action member 40 includes a first action member 41, which protrudes from the bottom end of the cover member 25 and extends obliquely from the front side of the cover member 25 toward the top surface of the box body 20. That is, the first action member 41 extends obliquely from the front side of the cover member 25 toward the upper surface 26, and one end of the first action member 41 extending from the cover member 25 abuts against the moving member 14.

[0086] In a possible implementation, the first acting member 41 is in the shape of a column extending obliquely.

[0087] In this embodiment, the first action member 41 and the moving member 14 are pressed against each other to push the moving member 14 to move in the second direction. When the first action member 41 initially contacts the moving member 14, the first action member 41 abuts against a side of the guide protrusion 144 that faces the inner bottom wall of the installation cavity 11, so that the first action member 41 pushes the moving member 14 to move upward in the second direction. As the ink cartridge further enters the installation cavity 11 along the first direction, the first action member 41 gradually extends into the opening 142 of the moving member 14.

[0088] Embodiment 2

[0089] refer to Figure 8 , Fig. 9 and Fig.10 As shown, in the second embodiment, the action member 40 includes a second action member 42, which extends to the front side of the cover member 25, and the second action member 42 extends obliquely from the top end of the cover member 25 toward the direction away from the top end surface of the box body 20, that is, the second action member 42 extends obliquely from the top end of the cover member 25 toward the direction away from the upper surface 26.

[0090] In a possible implementation, the second actuating member 42 is an elastic member. After the second actuating member 42 contacts the moving member 14 , under the interaction between the second actuating member 42 and the moving member 14 , the second actuating member 42 gradually tilts from the front side of the cover member 25 toward the inside of the hollow hole 252 .

[0091] In one possible implementation, a hanging ring 423 is formed at one end of the second acting member 42 away from the cover member 25, and a guide protrusion 144 is formed at one end of the movable member 14 facing the box body 20. During the process of installing the ink cartridge in the installation cavity 11, the hanging ring 423 is hooked on the side of the guide protrusion 144 that is opposite to the top surface of the box body 20, that is, the hanging ring 423 is hooked on the side of the guide protrusion 144 that is opposite to the upper surface 26.

[0092] In this embodiment, the hanging ring 423 is hooked on the side of the guiding protrusion 144 facing away from the upper surface 26 , so that the second acting member 42 drives the moving member 14 to move upward in the second direction.

[0093] During the process of installing the ink cartridge into the installation cavity 11 along the first direction, i.e., the X-axis direction, when the second action member 42 initially contacts the moving member 14, the second action member 42 abuts against a side of the guide protrusion 144 that faces the inner bottom wall of the installation cavity 11. As the depth of the ink cartridge entering the installation cavity 11 along the first direction, i.e., the X-axis direction, increases, the second action member 42 gradually sleeves on the outer side of the guide protrusion 144, so that the second action member 42 drives the moving member 14 to move upward along the second direction.

[0094] In one possible implementation, reference Fig.10 , Fig.11 and Fig.12 As shown, the side of the guide protrusion 144 facing the box body 20 is an inclined surface, which has a good guiding effect and ensures that the hanging ring 423 of the second action member 42 is gradually introduced to the outside of the guide protrusion 144.

[0095] In one possible implementation, the second active member 42 includes two connecting segments 421 and a hanging segment 422, the first ends of the connecting segments 421 are connected to the top of the cover member 25, the hanging segment 422 is connected between the second ends of the two connecting segments 421, and a hanging ring 423 is formed between the two connecting segments 421 and the one hanging segment 422.

[0096] In a possible implementation, the connecting segment 421 may be in the shape of a rod. The two connecting segments 421 may be arranged in parallel, or there may be an angle between the two connecting segments 421 .

[0097] In a possible implementation, an end of the second acting member 42 away from the cover member 25 is further away from the front surface 21 than the guide member 30 .

[0098] In one possible implementation, reference Fig.13 and Fig.14 As shown, in the height direction of the box body 20, that is, in the Z-axis direction, the action member 40 and the guide member 30 are both lower than the top surface of the box body 20, that is, the action member 40 and the guide member 30 are lower than the upper surface 26 of the box body 20. The action member 40 and the guide member 30 are prevented from affecting the installation of the ink cartridge into the installation cavity 11.

[0099] In a possible implementation, in the height direction of the box body 20, that is, in the Z-axis direction, the action member 40 is located on the upper side of the guide member 30, and the guide member 30 is located on the upper side of the ink outlet 23. The guide member 30 and the action member 40 are effectively prevented from interfering with the movement of the ink supply needle 12, thereby ensuring the ink supply effect.

[0100] In a possible implementation, the cover member 25 is lower than or parallel to the upper surface 26 of the box body 20 , thereby preventing the cover member 25 from affecting the installation of the ink cartridge into the installation cavity 11 .
