[0062] like Figure 1A and Figure 1B , Fig.24 As shown, the ink cartridge installation portion 300 has the same direction as the ink cartridge 100, and includes a mounting frame 301 and a plurality of side panels 302. The mounting frame 301 has an ink cartridge installation port 300a open toward the rear, and an insertion space 350 is formed between the side panel 302 and the mounting frame 301 and between two adjacent side panels 302. An ink absorbent needle 310, a stopper 320 and an electric contact needle assembly 300b are provided in each insertion space 350. The ink cartridge 100 is installed from the ink cartridge installation port 300a toward the ink cartridge installation portion 300.

[0063] The electric contact needle assembly 300b includes a carrier 300c, a first protrusion 300d, a second protrusion 300e and an electric contact needle 340. The first protrusion 300d and the second protrusion 300e both protrude in the same direction from the carrier 300c, and the first protrusion 300d protrudes farther than the second protrusion 300e. In the front-to-back direction, the first protrusion 300d is located in front of the second protrusion 300e, and the first protrusion 300d and the second protrusion 300e are arranged at an interval to form a contact cavity 300f therebetween. The electric contact needle 340 is located in the contact cavity 300f, and the electric contact needle 340 is arranged to move in the up-down direction relative to the carrier 300c. In the front-to-back direction, the electric contact needle assembly 300b / the electric contact needle 340 is located in front of the limiter 320, and in the up-down direction, the electric contact needle assembly 300b is located above the ink absorber 310.

[0064] like Figure 1B , Figure 2 , Figure 26A-26CAs shown, the ink cartridge 100 includes a box body 1 and an ink outlet 2 which are combined with each other, the box body 1 is used to contain ink, and the ink outlet 2 is used to supply ink to the imaging device; the ink cartridge 100 also includes a left side wall 100a facing the left, a right side wall 100b facing the right, a front side wall 100c facing the front, a rear side wall 100d facing the rear, an upper side wall 100e facing upward and a lower side wall 100f facing downward, the box body 1 includes a first shell 101a and a second shell 101b which are detachably combined, the ink cavity 106 is located between the first shell 101a and the second shell 101b, the ink outlet 2 is arranged on the first shell 101a or the second shell 101b, and the ink outlet 2 is connected to the ink cavity 106; no limitation is made on the direction in which the first shell 101a and the second shell 101b are combined.

[0065] In one embodiment, Figure 1A and Figure 2 , Fig.26A and Fig.26B As shown, the left side wall 100a is located in the first shell 101a, the right side wall 100b, the front side wall 100c, the rear side wall 100d, the upper side wall 100e and the lower side wall 100f are all located in the second shell 101b, and the ink outlet portion 2 is arranged on the second shell 101b.

[0066] In one embodiment, the box body 1 also has a sub-front side wall 100c1 and a sub-lower side wall 100f1. Along the up-down direction, the sub-front side wall 100c1 is located between the front side wall 100c and the lower side wall 100f. Along the front-to-back direction, the sub-lower side wall 100f1 is located between the front side wall 100c and the sub-front side wall 100c1. The ink outlet portion 2 is formed to protrude forward from the sub-front side wall 100c1.

[0067] In one embodiment, the box body 1 may not be provided with the sub-front side wall 100c1 and the sub-lower side wall 100f1, and the ink outlet portion 2 may be directly provided on the front side wall 100c. In this case, the ink outlet portion 2 protrudes forward from the front side wall 100c.

[0068] In the ink cartridge according to the present invention, the ink outlet portion 2 has an ink outlet 21 for allowing the ink suction needle 310 to enter, and the ink outlet 21 faces forward.

[0069] In one embodiment, a accommodating chamber 107 is further formed between the first shell 101a and the second shell 101b. Along the up and down directions, the accommodating chamber 107 and the upper side wall 100e are located above the ink chamber 106, and an intermediate partition 107a is arranged between the accommodating chamber 107 and the ink chamber 106.

[0070] Further, the ink cartridge 100 further includes a chip component 104 and a trigger mechanism 6. The chip component 104 is used to establish a communication connection between the ink cartridge 100 and the imaging device. Specifically, the chip component 104 includes a chip 104a and a combination portion / chip fixing seat 104b that are combined with each other. The combination portion / chip fixing seat 104b is used to install the chip 104a. The chip 104a and the combination portion 104b are movably combined. The combination portion 104b is connected to the box body 1. The chip 104a includes a substrate 104a2, an electrical contact portion 104a1 and a movable portion 104a3. For example, through the movable portion 104a3, the substrate 104a2 is movable relative to the combination portion 104b, such as Figure 1A As shown, the chip 104a can rotate around the rotation axis L relative to the coupling part 104b, and the rotation axis L intersects the up and down directions, or the movable part 104a3 and the coupling part 104b are slidably coupled, or the movable part 104a3 can both rotate and slide relative to the coupling part 104b.

[0071] As the ink cartridge 100 is installed toward the insertion space 350, the trigger mechanism 6 is triggered, and then the trigger mechanism 6 forces the chip 104a / electrical contact portion 104a1 to move from the electrically disconnected position to the electrically connected position. In the electrically disconnected position, the electrical contact portion 104a1 does not contact the electrical contact pin 340, and in the electrically connected position, the electrical contact portion 104a1 contacts the electrical contact pin 340; as the user operates the operating portion 105 located behind the ink cartridge 100, the ink cartridge 100 is gradually taken out of the insertion space 350, the trigger mechanism 6 is gradually reset, and the chip 104a / electrical contact portion 104a1 returns from the electrically connected position to the electrically disconnected position. Therefore, the chip 104a / electrical contact portion 104a1 involved in the present invention can move between the electrically disconnected position and the electrically connected position.

[0072] [Example 1]

[0073] like Figure 2 As shown, the electrical contact portion 104a1 in this embodiment is arranged on a surface of the substrate 104a2, and the movable portion 104a3 is arranged at one end of the substrate 104a2. Along the length direction of the substrate 104a2, the electrical contact portion 104a1 and the movable portion 104a3 are respectively located at two ends of the substrate 104a2. In this way, when the movable portion 104a3 is rotatably combined with the combining portion / chip fixing seat 104b, the electrical contact portion 104a1 can contact the electrical contact pin 340 without the substrate 104a2 rotating a large angle. In other words, this design is conducive to reducing the angle at which the substrate 104a2 needs to rotate.

[0074] The trigger mechanism 6 is movably arranged relative to the box body 1, and includes a trigger member 61 and a third reset member 62. The trigger member 61 is arranged to be movable between a protruding position and a trigger position. Before the ink cartridge 100 is installed, or before the trigger member 61 receives an external force, the trigger member 61 is located in the protruding position, and the chip 104a / electrical contact portion 104a1 is located in the electrically disconnected position; along the front-to-back direction, at least a portion of the trigger member 61 is located in front of the chip 104a / electrical contact portion 104a1, and the third reset member 62 is used to force the trigger member 61 to move toward the protruding position.

[0075] When the trigger member 61 receives an external force, the trigger member 61 moves from the protruding position to the trigger position, the third reset member 62 is elastically deformed, and the chip 104a / electrical contact portion 104a1 moves from the electrically disconnected position to the electrically connected position; when the trigger member 61 is at the trigger position, the chip 104a / electrical contact portion 104a1 is at the electrically connected position, at this time, the chip 104a / electrical contact portion 104a1 can be kept in contact with the electrical contact pin 340 by the trigger member 61 or other components.

[0076] In one embodiment, a portion of the trigger member 61 and at least a portion of the third reset member 62 are located in the accommodating cavity 107, and another portion of the trigger member 61 is located outside the accommodating cavity 107. In the up and down directions, the trigger member 61 exceeds the upper side wall 100e. This design can not only protect the trigger mechanism 6, but also reduce the size of the ink cartridge 100 in the up and down directions.

[0077] In one embodiment, the trigger mechanism 6 may also be completely located above the upper side wall 100e. In this case, the accommodating cavity 107 may not be required.

[0078] In one embodiment, the third restoring member 62 is configured as an elastic member. Figure 2 A third reset member 62 configured as a compression spring is shown, one end of the third reset member 62 abuts against the box body 1 , and the other end abuts against the trigger member 61 , so as to force the trigger member 61 to move toward the protruding position.

[0079] Specifically, the trigger member 61 has a force receiving surface / force receiving portion 614 for receiving external force and a force transmitting surface / force transmitting portion 612 for transmitting the force. The force receiving surface / force receiving portion 614 is used to abut against the interference surface / interference portion 303 in the imaging device / insertion space 350 to receive the external force, so that the trigger member 61 moves from the protruding position to the trigger position, and the force transmitting surface / force transmitting portion 612 is used to directly or indirectly transmit the force to the chip 104a / electrical contact portion 104a1, so that the chip 104a / electrical contact portion 104a1 moves from the electrically disconnected position to the electrically connected position.

[0080] Preferably, the interference surface / interference portion 303 is a certain component / group of components arranged in the imaging device. During the installation process of the ink cartridge 100, as long as the component can move the trigger member 61 from the protruding position to the trigger position, the interference surface / interference portion 303 can also be called an active member. For example, the active member is a protrusion arranged in the insertion space 350, or a color recognition component 200 arranged in the insertion space 350, and the color recognition component 200 is provided with an identification groove. Accordingly, the ink cartridge 100 is provided with a protruding component 3 that can enter the identification groove (as described in Example 3). Through the cooperation of the protruding component 3 and the identification groove, it is ensured that the ink cartridges with different color inks can be installed in the corresponding insertion space.

[0081] In one embodiment, the ink cartridge 100 is further provided with a retaining portion / retaining surface 613 for retaining the chip 104a / electrical contact portion 104a1 in an electrically connected position. Preferably, the retaining portion / retaining surface 613 is disposed on the trigger member 61, such as Figure 2 As shown, the force transmitting surface 612 and the retaining portion / retaining surface 613 are both arranged on the trigger portion 611 of the trigger member 61. Such an arrangement can simplify the structure of the trigger mechanism 6 / ink cartridge 100; along the front-to-back direction, the force receiving surface / force receiving portion 614 and the trigger portion 611 are respectively located at both ends of the trigger member 61.

[0082] In one embodiment, the retaining portion / retaining surface 613 may not be set on the trigger member 61. For example, the retaining portion / retaining surface 613 is set as a component that is linked to the trigger mechanism 6. During the movement of the trigger member 61 toward the trigger position, the retaining portion / retaining surface 613 gradually begins to contact the chip 104a / 104a1, so that the chip 104a / electrical contact portion 104a1 can be retained by the retaining portion / retaining surface 613; or, when the trigger member 61 reaches the trigger position, the chip 104a / electrical contact portion 104a1 is directly retained by the retaining portion / retaining surface 613.

[0083] In one embodiment, the force transfer surface 612 is configured as an inclined surface inclined relative to the front-rear direction, so that the force transfer surface 612b can transfer the force more smoothly.

[0084] In one embodiment, when the trigger member 61 is in the protruding position, the force transmission portion / force transmission surface 612 maintains contact with the chip 104a / substrate 104a2 / electrical contact portion 104a1. This design can improve the efficiency of force transmission on the one hand, and on the other hand, enable the chip 104a / electrical contact portion 104a1 in the electrically disconnected position to be stably supported.

[0085] In one embodiment, before the ink cartridge 100 is installed, at least a portion of the trigger member 61 is located above the chip 104a / electrical contact portion 104a1 in the up-down direction, so that the chip 104a / electrical contact portion 104a1 can be protected by the trigger member 61 even if the ink cartridge 100 falls.

[0086] like Figure 3A As shown, the ink cartridge 100 is installed in the forward direction toward the insertion space 350, the trigger member 61 is located in a protruding position, the ink suction needle 310 is aligned with the ink outlet 21 in the front-to-back direction, and the upper end of the trigger portion 611 is lower than the lower end of the second protrusion 300e in the up-down direction, and the upper end of the force receiving surface / force receiving portion 614 is lower than the lower end of the first protrusion 300d and the lower end of the second protrusion 300e. In this way, the ink cartridge 100 can be smoothly installed forward.

[0087] like Figure 3B As shown, as the ink cartridge 100 continues to be installed, the ink absorbing needle 310 enters the ink outlet portion 2 through the ink outlet port 21, the force receiving surface / force receiving portion 614 abuts against the interference surface / interference portion 303, the trigger member 61 overcomes the reset force of the third reset member 62 and moves backward, the force transmission surface / force transmission portion 612 pushes the substrate 104a2, so that the substrate 104a2 rotates around the rotation axis L, when the ink cartridge 100 reaches the predetermined position, the trigger member 61 is located at the trigger position, the force receiving surface / force receiving portion 614 maintains abutment with the interference surface / interference portion 303, in the contact cavity 300f, the electrical contact portion 104a1 contacts the electrical contact needle 340, and at the same time, the substrate 104a2 is supported by the support portion / support surface 613 so that the electrical contact portion 104a1 maintains stable contact with the electrical contact needle 340.

[0088] When the user applies a backward pulling force to the operating portion 105, the ink cartridge 100 begins to move backward, the third reset member 62 releases the reset force, the trigger member 61 begins to move from the trigger position toward the protruding position, and at the same time, the chip 104a / electrical contact portion 104a1 begins to move from the electrical connection position to the electrical disconnection position.

[0089] As described above, since the movable part 104a3 and the electrical contact part 104a1 of the chip 104a are respectively arranged at the two ends of the substrate 104a2, when the chip 104a / electrical contact part 104a1 is no longer supported by the supporting part / supporting surface 613, the chip 104a / electrical contact part 104a1 can move from the electrically connected position to the electrically disconnected position under the action of its own gravity; in other feasible embodiments, the chip 104a / electrical contact part 104a1 can also move from the electrically connected position to the electrically disconnected position under the action of the trigger mechanism 6.

[0090] [Example 2]

[0091] This embodiment will describe the locking portion 4 of the ink cartridge 100, which is used to lock the ink cartridge 100 in the imaging device / ink cartridge installation portion. Figure 4 As shown, the ink cartridge 100 in this embodiment is also provided with a chip component 104, and thus, the trigger mechanism 6 involved in the first embodiment is also applicable to this embodiment. In order to more clearly show the locking portion 4, the trigger mechanism 6 is not shown in the figure.

[0092] The locking portion 4 includes an abutting portion 42 and a fourth reset member 47. The abutting portion 42 is configured to be movable between a locked position and an unlocked position relative to the cartridge body 1. The fourth reset member 47 is used to force the abutting portion 42 to move toward the locked position. In the locked position, the abutting portion 42 abuts against a blocking portion provided in the imaging device / cartridge mounting portion 300 / insertion space 350 to lock the ink cartridge 100 in the imaging device / cartridge mounting portion 300 / insertion space 350. The electrical contact portion 104a1 is located in the electrical connection position. In the unlocked position, the abutting portion 42 is disengaged from the blocking portion. The blocking portion may be any component having a surface facing forward in the ink cartridge mounting portion 300 / insertion space 350, such as the first protrusion 300d or the second protrusion 300e. The blocking portion is located above the ink cartridge mounting portion 300 / insertion space 350.

[0093] In one embodiment, a receiving cavity 107 is provided in the ink cartridge 100 , and a portion of the fourth restoring member 47 and a portion of the abutting portion 42 are both located in the receiving cavity 107 , which helps the abutting portion 42 maintain a stable movement trajectory.

[0094] In one embodiment, the ink cartridge 100 does not need to have the accommodating chamber 107. For example, by providing a guide track on the upper side wall 100e, or extending the guide track upward from the upper side wall 100e, etc., it can also be ensured that the abutting portion 42 has a stable movement trajectory.

[0095] Furthermore, the abutment portion 42 has an extrusion surface 421 and a locking surface 422, and the extrusion surface 421 is used to receive the extrusion force by abutting against the blocking portion, thereby causing the fourth reset member 47 to deform, and the abutment portion 42 moves in the up and down directions, which is conducive to the locking portion 42 smoothly crossing the blocking portion, and the locking surface 422 is used to abut against the blocking portion to lock the ink cartridge 100.

[0096] like Figure 5AAs shown, during the process of installing the ink cartridge 100 forward along the front-to-back direction, the abutting portion 42 abuts against the second protrusion 300e and the first protrusion 300d in sequence. When the abutting portion 42 abuts against the second protrusion 300e, the extrusion surface 421 is extruded by the second protrusion 300e, and the abutting portion 42 overcomes the restoring force of the fourth restoring member 47 and moves downward. After the abutting portion 42 passes over the second protrusion 300e, the fourth restoring member 47 releases the restoring force, and the abutting portion 42 moves upward and enters the contact cavity 300f. As the ink cartridge 100 continues to be installed, the abutting portion 42 begins to abut against the first protrusion 300d, and the extrusion surface 421 is extruded by the first protrusion 300d again. The contact portion 42 overcomes the restoring force of the fourth restoring member 47 and moves downward again, the contact portion 42 passes over the first protrusion 300d and reaches the front of the first protrusion 300d, the fourth restoring member 47 releases the restoring force, and the contact portion 42 moves upward again. At this time, the ink cartridge 100 is installed to the predetermined position of the imaging device. Along the front-to-back direction, the locking surface 422 is located in front of the first protrusion 300d, and the locking surface 422 / contact portion 42 abuts against the first protrusion 300d, that is, the position where the locking surface 422 / contact portion 42 abuts against the first protrusion 300d is located in front of the electric contact pin 340, the abutment portion 42 is located in the locked position, and the ink cartridge 100 is locked in the imaging device.

[0097] In one embodiment, the abutment portion 42 can also be configured so that, during the installation process of the ink cartridge 100, the abutment portion 42 does not abut against the second protrusion 300e, but only abuts against the first protrusion 300d, thereby reducing the wear of the abutment portion 42 and also reducing the number of times the fourth reset member 47 is deformed.

[0098] In one embodiment, the locking portion 4 / abutment portion 42 can also be arranged behind the chip component 104 / electrical contact portion 104a1 along the front-to-back direction. During the installation process of the ink cartridge 100, the abutment portion 42 abuts against the second protrusion 300e and moves downward, and the fourth reset member 47 undergoes elastic deformation. When the abutment portion 42 passes over the second protrusion 300e, the fourth reset member 47 releases the elastic force, and the abutment portion 42 moves upward. Finally, the abutment portion 42 locks the ink cartridge 100 by abutting against the second protrusion 300e.

[0099] In one embodiment, the fourth reset member 47 is configured as an elastic member that can undergo elastic deformation. Specifically, the fourth reset member 4 is configured as a compression spring or a tension spring or rubber or silicone or sponge or the like.

[0100] In one embodiment, along the up-down direction, the highest point of the abutment portion 42 is higher than the electrical contact portion 104a1. When the center line L2 of the ink outlet portion 2 is used as a reference, along the up-down direction, the distance between the highest point of the abutment portion 42 and the center line L2 is greater than the distance between the electrical contact portion 104a1 and the center line L2. Therefore, before the ink cartridge 100 is installed, or when the locking portion 4 is in the unlocked position, at least the electrical contact portion 104a1 can be protected by the abutment portion 42.

[0101] The ink cartridge 100 having this structure can be installed and removed in a direction parallel to the front-rear direction, so that the lower side wall 100f of the ink cartridge 100 can be set to a plane, thereby simplifying the structure of the ink cartridge 100.

[0102] [Example 3]

[0103] In this embodiment, the ink cartridge 100 is also provided with a protruding member 3 protruding from the upper side wall 100e, and the protruding member 3 is at least used to cooperate with the color recognition member 200 provided in the imaging device / ink cartridge installation portion 300 / insertion space 350; when a light detection member is also provided in the insertion space 350, the protruding member 3 cooperates with the light detection member to detect at least one of the information such as whether the ink cartridge 100 is installed and the model of the ink cartridge 100; along the front-to-back direction, the light detection member / color recognition member 200, the electric contact pin 340 and the limit member 320 are arranged in sequence.

[0104] like Figure 6 As shown, the protruding member 3 includes a front surface 3a facing forward, an upper surface 3b facing upward, and a connecting surface 3c connecting the front surface 3a and the upper surface 3b, wherein the connecting surface 3c is inclined relative to the front-to-back direction. Figure 6 In the state shown, or when viewed in the left-right direction, the connecting surface 3c intersects with the upper surface 3b at a point P2, which is also the highest point of the connecting surface 3c / protruding member 3 in the up-down direction.

[0105] In one embodiment, along the front-to-back direction, the locking portion 4 in this embodiment is arranged behind the chip component 104. Figure 6 As shown, the locking portion 4 protrudes from the upper side wall 100e and is provided with an extrusion surface 421 and a locking surface 422. The extrusion surface 421 is inclined relative to the front and rear directions. During the installation of the ink cartridge 100 toward the insertion space 350, the extrusion surface 421 and the limiting member 320 are pressed against each other until the extrusion surface 421 passes over the limiting member 320. Subsequently, the locking surface 422 located behind the extrusion surface 421 abuts against the limiting member 320, and the ink cartridge 100 is locked in the imaging device / ink cartridge installation portion 300 / insertion space 350.

[0106] When the ink cartridge 100 is observed along the left-right direction, the highest point of the extrusion surface 421 is point P1, and the line connecting point P1 and point P2 is X1. In the up-down direction, point P2 is lower than point P1. In one embodiment, before the ink cartridge 100 is installed, in the chip component 104, at least the electrical contact portion 104a1 is located above the line X1 along the up-down direction, thereby ensuring that the electrical contact portion 104a1 is in close contact with the electrical contact pin 340.

[0107] In one embodiment, before the ink cartridge 100 is installed, the entire chip component 104 is located below the line X1 in the up and down direction. This design can reduce the risk of the chip component 104 being touched by external parts before the ink cartridge 100 is installed in the insertion space 350.

[0108] As described above, the locking portion 4 and the chip member 3 both protrude from the upper side wall 100 e , and thus, the locking portion 4 and the chip member 3 can be regarded as a first protrusion and a second protrusion provided in the ink cartridge 100 , respectively.

[0109] Among them, the first protrusion 4 can be fixedly set on the box body 1, or can be movably set relative to the box body 1, and the first protrusion 4 may not have a locking surface 422. In this case, the ink cartridge 100 can be locked in the imaging device by setting a locking surface 422 in other places. For example, the ink cartridge 100 is locked by utilizing the friction between the ink suction needle 310 and the ink outlet part 2, or a locking surface 422 is set in the lower side wall 100f of the box body 1, and the ink cartridge 100 is locked by engaging the locking surface 422 with the imaging device.

[0110] The second protrusion 3 can be fixedly arranged on the box body 1, and can also be movably arranged relative to the box body 1, and the second protrusion 3 at least has the function of cooperating with the identification groove so that the ink cartridges with different color inks can be installed in the corresponding insertion space. When a light detection component is also provided in the imaging device, the second protrusion 3 is also provided with a light shielding portion for cooperating with the light detection component. The imaging device determines whether the ink cartridge 100 is installed and at least one of the information such as the model of the ink cartridge 100 by detecting whether the light emitted by the light detection component is blocked by the light shielding portion. The point P2 is the highest point of the light shielding portion.

[0111] Continue as Figure 6 As shown, the ink cartridge 100 also includes a protective member 9 that is movable relative to the box body 1. Along the front-to-back direction, at least a portion of the protective member 9 is located between the locking portion 4 and the protruding member 3. The protective member 9 includes a protective portion 91 and a fifth reset member 92. The protective portion 91 is movable between an extended position and a retracted position relative to the box body 1. The fifth reset member 92 is used to force the protective portion 91 to move toward the extended position.

[0112] In one embodiment, the protective member 9 may be made entirely of elastic material and have elasticity. The protective member 9 is installed on the cartridge body 1. During the installation of the ink cartridge 100, the protective member 9 is elastically deformed so that the ink cartridge 100 can be installed smoothly.

[0113] Before the ink cartridge 100 is installed, when the protecting portion 91 is in the extended position, a portion of the protecting member 9 / a portion of the protecting portion 91 exceeds the connecting line X1 in the up and down directions, or in other words, the connecting line X1 passes through the protecting member 9 / the protecting portion 91, so that, among the protruding member 3 and the locking portion 4, at least the protruding member 3 in the lower position can be protected by the protecting portion 91, especially when the entire chip member 104 is located below the connecting line X1, the chip member 104 can also be protected by the protecting portion 91.

[0114] In one embodiment, the connecting line X1 may also be tangent to the highest position of the protecting member 9 / protecting portion 91 in the up-down direction, so that at least the protruding member 3 at a lower position can be protected by the protecting portion 91 .

[0115] In one embodiment, before the ink cartridge 100 is installed, the protective member 9 / protective portion 91 in the extended position is higher than the chip component 104 / electrical contact portion 104a1 along the up and down direction, so that the chip component 104 / electrical contact portion 104a1 can be better protected by the protective portion 91.

[0116] In the front-to-back direction, the protective member 9 / protective portion 91 is located in front of the chip component 104 / electrical contact portion 104a1. As the ink cartridge 100 is installed toward the insertion space 350, when the protective portion 91 contacts any one of the second protrusion 300e, the electrical contact pin 340, and the first protrusion 300d (which can be regarded as another embodiment of the interference portion 303), the protective portion 91 will overcome the restoring force of the fifth restoring member 92 and move toward the retracted position / downward. When the protective portion 91 passes over the interference portion 303, the fifth restoring member 92 releases the restoring force, and the protective portion 91 will be reset from the retracted position to the extended position / upward.

[0117] In one embodiment, the protection member 9 / protection portion 91 is located behind the chip component 104 / electrical contact portion 104a1. In this case, the blocking portion may be the second protrusion 300e or a component located behind the carrier 300c.

[0118] In one embodiment, when the protective member 9 / protecting portion 91 is in the extended position, the ink cartridge 100 is locked in the imaging device by the abutment between the protective portion 91 and the blocking portion along the front-to-back direction. When the protective member 9 / protecting portion 91 is in the retracted position, the protective portion 91 no longer abuts against the blocking portion, and the ink cartridge 100 is unlocked. Therefore, the protective member 9 in this embodiment can also be regarded as an embodiment of the locking portion 4. At this time, the protective portion 91 is equivalent to the abutment portion 42, and the fifth reset member 92 is equivalent to the fourth reset member 47; in this variation and the structure described in Example 2, along the front-to-back direction, the protruding member 3, the protective member 9 / protecting portion 91 and the chip member 104 / electrical contact portion 104a1 are arranged in sequence from front to back, or the protruding member 3, the chip member 104 / electrical contact portion 104a1 and the protective member 9 / protecting portion 91 are arranged in sequence from front to back.

[0119] [Example 4]

[0120] This embodiment will describe the locking portion 4 of the ink cartridge 100, which is used to lock the ink cartridge 100 in the imaging device / ink cartridge installation portion. Figure 7-Figure 9 As shown, the ink cartridge 100 in this embodiment is also provided with a chip component 104, so the trigger mechanism 6 involved in the first embodiment is also applicable to this embodiment. In order to more clearly show the locking portion 4, the trigger mechanism 6 is not shown in the figure. The difference between this embodiment and the second embodiment is that the operating portion 105 in this embodiment is movably arranged relative to the cartridge body 1, and can limit the movement of the locking portion 4 between the locked position and the unlocked position; specifically, the operating portion 105 has a first state that limits the movement of the locking portion 4 from the unlocked position to the locked position and a second state that allows the locking portion 4 to move from the locked position to the unlocked position.

[0121] The locking portion 4 includes an abutment portion 42, a guide portion 48 and a fourth reset member 47. The guide portion 48 is used to guide the movement of the abutment portion 42. The abutment portion 42 is configured so that the abutment portion 42 can move between a locked position and an unlocked position relative to the box body 1. The fourth reset member 47 is used to force the abutment portion 42 to move toward the locked position. In the locked position, the abutment portion 42 abuts against a blocking portion provided in the imaging device / cartridge installation portion 300 / insertion space 350 to lock the ink cartridge 100 in the imaging device / cartridge installation portion 300 / insertion space 350. The electrical contact portion 104a1 is located in the electrical connection position. Please note that the locking position of the abutment portion 48 is different from that of Example 2 in that: in the locked position, the operating portion 105 is simultaneously in the first state, and the operating portion 105 abuts against the guide portion 48 / abutment portion 42, so that the abutment portion 42 cannot be disengaged from the blocking portion under the restriction of the operating portion 105. When the operating part 105 is in the second state, that is, the operating part 105 releases the restriction on the guide part 48 / the contact part 42, and then the contact part 42 can move backwards from the ink cartridge 100 to the ink cartridge installation part 300, and can be disengaged from the contact part under the action of gravity / pushed by the blocking part, and then move from the locked position to the unlocked position. The blocking part can be any component with a surface facing forward in the ink cartridge installation part 300 / the insertion space 350, such as the first protrusion 300d or the second protrusion 300e.

[0122] Specifically, the operating portion 105 includes a guiding inclined surface 1051 facing the locking portion 4, and the guiding portion 48 is arranged at the lower side of the abutting portion 42 and abuts against the guiding inclined surface 1051; under the elastic force of the fourth reset member 47, the abutting portion 42 has a tendency to abut against the blocking portion.

[0123] In this embodiment, the fourth reset member 47 is arranged between the operating portion 105 and the box body 1. Preferably, a reset member accommodating cavity 1052 is provided in the operating portion 105, and the reset member accommodating cavity 1052 is used to accommodate the fourth reset member 47 and guide and limit it. The operating portion 105 has a tendency to move toward the first state under the elastic force of the fourth reset member 47; in other words, when the operating portion 105 is in the first state under the elastic force of the fourth reset member 47, the guiding inclined surface 1051 of the operating portion 105 cooperates with the guiding portion 48. , so that the abutment portion 42 remains in the locked position (even if the abutment portion 42 does not abut against the blocking portion, it can be regarded as being in the locked position); when the ink cartridge 100 installed in the ink cartridge installation portion 300 needs to be taken out, the operating portion 105 can be controlled to overcome the elastic force of the fourth reset member 47 and move to the second state. At this time, the guide slope 1051 moves backward and no longer restricts the abutment portion 42, and then the abutment portion 42 moves from the locked position to the unlocked position under the action of gravity, and then the ink cartridge 100 is further pulled and separated from the ink cartridge installation portion 300 as a whole.

[0124] In one embodiment, the fourth reset member 47 can also be set in a manner similar to that of Example 2, that is, the fourth reset member 47 is set between the abutment portion 42 and the box body 1, and the operating portion 105 is no longer affected by the elastic force of the fourth reset member 47 and moves between the first state and the second state; optionally, the operating portion 105 can be moved between the first state and the second state by manual control of the user; optionally, the size of the operating portion 105 in the front-to-back direction can also be set to be farther away from the front side wall 100c than the rear side wall 100d of the box body, and by closing the door cover of the imaging device / cartridge installation portion 300, the operating portion 105 can be pushed by the door cover (not shown in the figure) / protrusion on the door cover of the imaging device / cartridge installation portion 300, thereby remaining in the first state.

[0125] In one embodiment, the trigger mechanism / operating part (not shown in the figure) can be movably arranged in the manner of the aforementioned embodiment, and the trigger mechanism / operating part can drive the chip 104a to produce displacement in the up-down direction. When the ink cartridge 100 is installed as a whole to the preset position in the ink cartridge installation part 300, the chip 104a / electrical contact part 104a1 is still in the electrically disconnected position at this time. By closing the door cover of the imaging device / ink cartridge installation part 300, the trigger mechanism / operating part of this embodiment can be pushed by the door cover (not shown in the figure) / protrusion on the door cover of the imaging device / ink cartridge installation part 300 to produce displacement in the front-back direction, so that the trigger mechanism / operating part can force the chip 104a / electrical contact part 104a1 to produce displacement in the up-down direction and move from the electrically disconnected position to the electrically connected position. Among them, the door cover is used to close the opening of the ink cartridge installation part 300, which is a prior art and will not be repeated here.

[0126] In one embodiment, Fig. 9 As shown, the protruding member 3 includes a front surface 3a facing forward, an upper surface 3b facing upward, and a connecting surface 3c connecting the front surface 3a and the upper surface 3b, wherein the connecting surface 3c is inclined relative to the front-to-back direction. Fig. 9 In the state shown, or in other words, when viewed in the left-right direction, the connecting surface 3c intersects with the upper surface 3b at point P2, and in the up-down direction, point P2 is also the highest point of the connecting surface 3c / protruding member 3. In the front-back direction, another protruding member 4a is arranged behind the chip member 104, as shown in FIG. Fig. 9 As shown, another protruding member 4a protrudes from the upper side wall 100e.

[0127] When the ink cartridge 100 is observed along the left-right direction, the highest point of the other raised component 4a is point P1, and the line connecting point P1 and point P2 is X1. In the up-down direction, point P2 is lower than point P1. In one embodiment, before the ink cartridge 100 is installed, in the up-down direction, in the chip component 104, at least the uppermost end of the locking portion 4 / abutting portion 42 is located above the line X1. In this way, when the ink cartridge 100 falls, the locking portion 4 / abutting portion 42 can protect the chip component 104.

[0128] In one embodiment, the other protruding member 4a located at the rear side of the chip member 104 may be omitted.

[0129] The beneficial effect of this embodiment, compared with the second embodiment, is that by setting the operating part 105 in a movable manner, the force required for the locking part 4 / abutment part 42 to move from the locking position to the unlocking position is increased, thereby making the installation of the ink cartridge 100 in the ink cartridge installation part 300 more stable.

[0130] [Example 5]

[0131] This embodiment will mainly describe the chip component 104 of the ink cartridge 100. Figure 10-11 The difference between this embodiment and the fourth embodiment is that the combining portion / chip fixing seat 104b of this embodiment is integrally arranged with the locking portion 4, and the chip 104a is fixedly arranged on the combining portion 104b, that is, when the ink cartridge 100 is installed to the predetermined position of the ink cartridge installation portion 300, the locking portion 4 / abutting portion 42 moves to the locking position and abuts against the blocking portion, and at the same time drives the chip 104a / electrical contact portion 104a1 to produce a displacement in the up and down directions and move from the electrically disconnected position to the electrically connected position.

[0132] In this embodiment, the integrally arranged combination portion 104b and the locking portion 4 can rotate relative to the box body 1 around the axis L, and the abutment portion 42 can abut against the first protrusion 300d. In other embodiments, the integrally arranged combination portion 104b and the locking portion 4 can also generate vertical displacement relative to the box body 1, such as sliding in the vertical direction, or sliding in a direction inclined to the front-rear direction.

[0133] [Example 6]

[0134] like Fig.12 , Fig.13 and Fig.14 As shown, this embodiment will continue to describe the locking portion 4 of the ink cartridge 100, which is used to lock the ink cartridge 100 in the imaging device / ink cartridge installation portion. In this embodiment, the locking portion 4 is configured as a cantilever located on the first shell 101a or the second shell 101b. The following description takes the locking portion 4 being configured on the second shell 101b as an example.

[0135] The locking portion 4 can move between a locking position and an unlocking position. In the locking position, the abutting portion 42 abuts against a blocking portion provided in the imaging device / ink cartridge installation portion 300 / insertion space 350 to lock the ink cartridge 100 in the imaging device / ink cartridge installation portion 300 / insertion space 350, and the electrical contact portion 104a1 is located in an electrical connection position. In the unlocking position, the abutting portion 42 is disengaged from the blocking portion, and the electrical contact portion 104a1 is located in an electrical disconnection position. The blocking portion can be any component in the ink cartridge installation portion 300 / insertion space 350 that has a surface facing forward, such as the first protrusion 300d or the second protrusion 300e.

[0136] The locking portion 4 includes a main body 108 and an abutting portion 42 connected to each other. The main body 108 is connected to at least one of the first shell 101a, the second shell 101b and the middle partition 107a. The abutting portion 42 is configured as a cantilever extending upward.

[0137] The abutment portion 42 has an extrusion surface 421 and a locking surface 422. The extrusion surface 421 is used to receive the extrusion force by abutting against the blocking portion. At least a portion of the abutment portion 42 is elastically deformed downward so that the locking portion 42 can smoothly pass over the blocking portion. The locking surface 422 is used to abut against the blocking portion so that the ink cartridge 100 is locked.

[0138] Specifically, in the present embodiment, during the process of installing the ink cartridge 100 into the imaging device / ink cartridge mounting portion 300 / insertion space 350 in the forward direction, the abutment position of the extrusion surface 421 and the electric contact needle assembly 300b can refer to the second embodiment. After the extrusion surface 421 abuts against the electric contact needle assembly 300b, at least a portion of the abutment portion 42 elastically deforms downward until the abutment portion 42 passes over the blocking portion, or in other words, the abutment portion 42 reaches the front of the blocking portion, the extrusion surface 421 is disengaged from the abutment with the blocking portion, the abutment portion 42 no longer elastically deforms, the locking surface 422 abuts against the front surface of the electric contact needle assembly 300b, and the ink cartridge 100 is locked. It can be seen that when the ink cartridge 100 is installed to the predetermined position toward the ink cartridge mounting portion 300, in the front-to-back direction, the position where the locking surface 422 abuts against the blocking portion is located in front of the electric contact needle 340.

[0139] In one embodiment, the abutment portion 42 is located in front of or behind the main body 108 .

[0140] In one embodiment, the abutting portion 42 is configured to be an irregular shape, which facilitates elastic deformation of the abutting portion 42 .

[0141] In one embodiment, the locking portion 4 also includes a first support member 44 extending in the up-down direction, and at least one of the main body 108, the first shell 101a, the second shell 101b and the middle partition 107a is connected to the first support member 44. The first support member 44 is used to support the abutment portion 42 so that the locking surface 422 and the forward surface of the electric contact needle assembly 300b can be more stably abutted. In this way, the ink cartridge 100 can be more stably locked in the imaging device / ink cartridge installation portion 300 / insertion space 350.

[0142] like Fig.14 As shown, the ink outlet 2 also includes a sealing plug 22 disposed inside the ink outlet 21, an outer cover 23 disposed outside the ink outlet 21, and an adsorbent 24 disposed inside the outer cover 23. Further, the adsorbent 24 is located between the outer cover 23 and the sealing plug 22. The outer cover 23 is used to fix the sealing plug 22 to prevent the sealing plug 22 from coming out. When the ink cartridge is taken out from the ink cartridge mounting portion 300 to the rear, the adsorbent 24 can adsorb the ink on the outer wall of the ink absorbing needle 310 to prevent the ink remaining on the outer wall of the ink absorbing needle 310 from contaminating the ink cartridge mounting portion 300. Further, a part of the adsorbent 24 is located inside the ink outlet 21 to be combined with the sealing plug 22, and another part is located outside the ink outlet 21. The other part of the adsorbent 24 can be combined with the outer cover 23 or not. The ink outlet 2 is also provided with a protective plug 25. During the transportation of the ink cartridge 100, the protective plug 25 is disposed inside and outside the ink outlet 21 to seal the entire ink outlet 2.

[0143] In some embodiments, the box body 1 is further provided with an elastic arm 101 c that interacts with the outer cover 23 to fix the outer cover 23 . Preferably, the elastic arm 101 c is engaged with the outer cover 23 .

[0144] In this embodiment, the locking portion 4 / abutment portion 42 is arranged on the first shell 101a / second shell 101b instead of on the chip component 104. The locking portion 4 / abutment portion 42 no longer moves with the chip component 104 / combining portion / chip fixing seat 104b, which can improve the stability of the abutment between the locking portion 4 / abutment portion 42 and the electrical contact pin assembly 300b.

[0145] [Example 7]

[0146] like Fig.15 and Fig.17 As shown, the middle partition 107a includes a first partition 107a1, a fourth partition 107a2, and a step portion 109 located between the first partition 107a1 and the fourth partition 107a2, and the step portion 109 has a step surface 107m1 facing upward.

[0147] like Fig.15 , Fig.16 , Fig.17 and Fig.18 As shown, the ink cartridge 100 also includes an atmosphere connecting piece and an air guiding component 110. The air guiding component 110 is movably arranged relative to the box body 1, and is used to directly or indirectly open or close the atmosphere connecting piece. The atmosphere connecting piece is used to connect the ink chamber 106 with the atmosphere. The atmosphere connecting piece includes an air guiding port 110b and a gas connecting channel 140 that are interconnected. The air guiding port 110b is used to connect the atmosphere and the gas connecting channel 140. The gas connecting channel 140 is used to connect the air guiding port 110b with the ink chamber 106. The atmosphere can enter the ink chamber 106 through the air guiding port 110b and the gas connecting channel 140.

[0148] The air guide component 110 includes a sealing member 110d, and the air guide component 110 can be switched between a sealing position and an unsealing position. The sealing position, i.e., the air guide port 110b is sealed by the sealing member 110d, and the ink chamber 106 is not connected to the atmosphere. The unsealing position, i.e., the air guide port 110b is not sealed by the sealing member 110d, and the ink chamber 106 is connected to the atmosphere.

[0149] like Fig.19 and Fig. 20 As shown, in this embodiment, the locking portion 4 is also configured as a cantilever. Unlike the sixth embodiment, the locking portion 4 is disposed on the air guide member 110. Specifically, the locking portion 4 is located on the sealing member 110d of the air guide member 110. The locking portion 4 is connected to or integrally formed with the sealing member 110d. The locking portion 4 includes an abutting portion 42 having an extrusion surface 421 and a locking surface 422. During the process of installing the ink cartridge 100 to the imaging device, the movement process of the abutting portion 42 over the blocking portion in the electric contact needle assembly 300b is consistent with that of the sixth embodiment. It can be seen that when the ink cartridge 100 is installed to the imaging device, the abutting portion 42 moves over the blocking portion in the electric contact needle assembly 300b. 00 is installed to a predetermined position toward the ink cartridge installation portion 300, in the front-to-back direction, the position where the locking surface 422 abuts against the blocking portion is located in front of the electric contact pin 340, and after the abutting portion 42 passes over the blocking portion, at this time, the sealing member 110d abuts against the ink cartridge installation portion 300 and moves backward relative to the second shell 101b, and the sealing member 110d moves from the sealing position to the unsealing position, and the abutting portion 42 moves backward with the sealing member 110d, so that the locking surface 422 abuts against the front surface of the electric contact pin assembly 300b, and the ink cartridge 100 is locked.

[0150] In one embodiment, the locking portion 4 also includes a second support member 45 protruding rearward from the locking surface 422, and the second support member 45 is used to support the chip fixing seat 104b in the chip component 104, thereby improving the stability of the electrical connection between the chip 104a and the electrical contact pin 340 in the electrical contact pin assembly 300b.

[0151] In one embodiment, a third support member 46 is further provided on the first shell 101a / the second shell 101b, and at least one of the step portion 109, the first shell 101a, the second shell 101b and the middle partition 107a is connected to the third support member 46, and the third support member 46 is used to support the second support member 45. Through such a configuration, the stability of the electrical connection between the chip 104a and the electrical contact pin 340 can be better improved.

[0152] [Beneficial Effects]

[0153] In the present invention, the ink cartridge 100 provided in the above-mentioned embodiments 1 to 7 has the following beneficial effects compared with the prior art:

[0154] On the first aspect, the locking portion 4 in the ink cartridge 100 is configured as a cantilever, and the locking portion 4 is arranged on the first shell 101a / the second shell 101b. The locking portion 4 / the abutment portion 42 elastically deforms itself under the action of an external force and accumulates a reset force. After the external force is removed, the reset force is released, and the locking portion 4 / the abutment portion 42 is reset. In this way, the locking portion 4 / the abutment portion 42 can realize movement in the up and down directions, thereby locking the ink cartridge 100 in the imaging device / the ink cartridge installation portion 300 / the insertion space 350.

[0155] Alternatively, the locking portion 4 can also be arranged on the sealing member 110d in the air guide member 110. The locking portion 4 / abutment portion 42 can generate elastic deformation and accumulate reset force under the action of external force. After the external force is removed, the reset force is released, and the locking portion 4 / abutment portion 42 is reset. In this way, the locking portion 4 / abutment portion 42 can realize movement in the up and down directions. After that, the locking portion 4 / abutment portion 42 realizes the abutment of the locking surface 422 with the forward surface of the electric contact needle assembly 300b by moving backward with the sealing member 110d, thereby locking the ink cartridge 100 in the imaging device / ink cartridge installation portion 300 / insertion space 350.

[0156] The ink cartridge 100 having the above-mentioned configuration has a more compact structure, thereby improving the design freedom of the ink cartridge 100 .

[0157] Secondly, the locking portion 4 is not disposed on the chip component 104, and the locking portion 4 / abutting portion 42 no longer moves with the chip component 104 / chip fixing seat 104b, so that the locking portion 4 / abutting portion 42 abuts against the electrical contact pin assembly 300b more stably.

[0158] Thirdly, when the locking portion 4 is disposed on the air guide member 110, the locking portion 4 also includes a second support member 45 or a second support member 45 and a third support member 46. Through such an arrangement, the stability of the electrical connection between the chip 104a / electrical contact portion 104a1 and the electrical contact pin 340 can be further improved.

[0159] [Embodiment 8]

[0160] like Fig.21 As shown, the imaging device further comprises a door cover PC movable relative to the ink cartridge installation portion 300, for example, the door cover PC rotates or moves in a translation relative to the ink cartridge installation portion 300, as shown in FIG. Fig.21 As shown, the door cover PC includes a cover plate PC1 and a movable portion PC2, and the cover plate PC1 is configured to be able to rotate around the movable portion PC2 and move between a closed position closing the ink cartridge installation port 300a and an open position opening the ink cartridge installation port 300a; in some imaging devices, the door cover PC also includes a protrusion PC3 connected to the cover plate PC1, and the protrusion PC3 protrudes from the cover plate PC1 toward the insertion space 350.

[0161] In this embodiment, the chip fixing seat 104b serving as a coupling portion is also arranged to be movable relative to the box body 1, so that the electrical contact portion 1041 can move between the electrically disconnected position and the electrically connected position. It can be realized that the chip fixing seat 104b is arranged in a rotational and translational manner relative to the box body 1. The chip fixing seat 104b shown in this embodiment slides relative to the box body 1.

[0162] like Fig. 22 As shown, the chip fixing seat 104b is provided with a guided member 104b1, and the box body 1 is provided with a guiding member 107g for guiding the guided member 104b1. For example, the guided member 104b1 is set to be in a protrusion shape, and the guiding member 107g is set to be in a groove shape. The guiding groove 107g can extend in a direction parallel to the up and down direction, or can be set in an inclined direction inclined relative to the up and down direction, or can be set to be curved, but as a whole, the guiding groove 107g extends in the up and down direction; or, the guided member 104b1 is set to be in a groove shape, and the guiding member 107g is set to be in a protrusion shape.

[0163] The trigger mechanism 6 in this embodiment also includes a trigger member 61. In some embodiments, the trigger member 61 is configured as a movable rod that can rotate around a rotation axis L1. The extension direction of the rotation axis L1 does not need to be limited, as long as the trigger member 61 can generate displacement in the up and down directions. Preferably, the rotation axis L1 extends in the left and right direction.

[0164] On the whole, the trigger member 61 in this embodiment is lever-shaped and has a rotating portion 615. The force receiving portion 614 and the trigger portion 611 are respectively located at both ends of the trigger member 61. Specifically, the force receiving portion 614 is provided with a force receiving surface 6141 for receiving external force, and the force transmitting portion 612 and the retaining portion 613 are both arranged on the trigger portion 611. Preferably, the force receiving surface 6141 is arranged as an inclined surface inclined relative to the front and rear directions, so as to facilitate smoother reception of external force.

[0165] Furthermore, the accommodating cavity 107 also has an exposure opening 1071 facing the rear, and the trigger member 61 is arranged in the accommodating cavity 107 and exposed rearward through the exposure opening 1071. Specifically, when the ink cartridge 100 is not installed to the ink cartridge installation portion 300, at least the force receiving portion 614 is located behind the exposure opening 1071.

[0166] like Fig.23A As shown, before the ink cartridge 100 is installed in the ink cartridge installation portion 300, or after the ink cartridge 100 is installed in the ink cartridge installation portion 300, but the door cover PC has not yet been closed, the electrical contact portion 1041 is located at the electrically disconnected position, the trigger member 61 is located at the protruding position, the lifted member 104b7 of the chip fixing seat 104b is supported by the trigger portion 611, and the force receiving portion 614 is located at a position away from the ink outlet portion 2 in the up and down direction; when the ink cartridge 100 is in the installed state of being installed in the imaging device / ink cartridge installation portion 300, as the door cover PC rotates around the movable portion PC2 in the direction shown by r2, the protrusion PC 3 gradually approaches the force receiving surface 6141. When the two begin to contact, the protrusion PC3 presses the force receiving surface 6141, the force receiving portion 614 receives the force from the door cover PC, and gradually moves downward. Compared with the far position, along the up and down direction, the force receiving portion 614 is closer to the ink outlet portion 2 and is located in the close position, and the trigger member 61 rotates around the rotating portion 615 along the direction indicated by r1. According to the force, or under the action of the force, the trigger portion 611 / the force transmitting portion 612 pushes the chip fixing seat 104b to move upward, and the trigger member 61 moves from the protruding position to the trigger position.

[0167] like Fig. 23B As shown, when the door cover PC is in a closed state, the force receiving portion 614 is pressed by the bump PC3 and maintained in a close position, the chip fixing seat 104b is held by the holding portion 613, the electrical contact portion 104a1 enters the contact cavity 300f and maintains contact with the electrical contact pin 340, and the trigger member 61 reaches the trigger position.

[0168] When the door cover PC is not provided with the protrusion PC3, the force receiving portion 614 in this embodiment can directly abut against the cover PC1 and move from the distant position to the close position, and when the force receiving portion 614 reaches the close position, the force receiving portion 614 is pressed by the cover PC1 and maintained in the close position.

[0169] It can be seen that no matter whether the force receiving portion 614 is directly pressed by the cover plate PC1 and maintained in the close position, or is pressed by the protrusion PC3 and maintained in the close position, as the door cover PC opens, the trigger member 61 will automatically reset under the action of its own gravity and the gravity of the chip mechanism 104, and the force receiving portion 614 returns from the close position to the distant position. The trigger mechanism 6 in this embodiment does not need to be provided with a reset member for forcing the trigger member 61 to reset, thereby, the structure of the trigger mechanism 6 can be simplified.

[0170] It can be seen that in this embodiment, the locking portion 4 is arranged on the trigger member 61, that is, the force receiving portion 614 is regarded as the locking portion 4. When the door cover PC is closed, the door cover PC abuts against the force receiving portion 614, and the ink cartridge 100 is locked. When the door cover PC is opened, the door cover PC is disengaged from the force receiving portion 614, and the ink cartridge 100 is unlocked.

[0171] In some embodiments, before the ink cartridge 100 is installed in the ink cartridge installation portion 300, or after the ink cartridge 100 is installed in the ink cartridge installation portion 300 but before the door cover PC is closed, the force receiving portion 614 may not be located behind the exposure port 1071. At this time, the force receiving portion 614 is "retracted" in the accommodating cavity 107, but the force receiving portion 614 is exposed backward through the exposure port 1071. During the closing process of the door cover PC, the force receiving portion 614 reaches the rear of the exposure port 1071, thereby preventing the electrical contact portion 104a1 from moving toward the electrical connection position due to the force receiving portion 614 accidentally receiving the force.

[0172] In some embodiments, the trigger member 61 can also be set to move in a linear manner. For example, after receiving the force of the door cover PC, the trigger member 61 moves in a linear manner in a direction intersecting the left and right directions. Preferably, the trigger member 61 moves in a direction parallel to the front and back directions. At this time, at least one of the trigger portion 611 and the chip fixing seat 104b is provided with an inclined surface that can transmit the force, so that the electrical contact portion 104a1 moves from the electrically disconnected position to the electrically connected position. When the force is removed, the electrical contact portion 104a1 returns from the electrically connected position to the electrically disconnected position.

[0173] In some embodiments, the trigger member 61 can also be interconnected with the chip fixing seat 104b to form a whole, which, after receiving the force applied by the door cover PC, rotates or translates the electrical contact portion 104a1 from the electrically disconnected position to the electrically connected position, and when the force is removed, the electrical contact portion 104a1 returns from the electrically connected position to the electrically disconnected position; in this embodiment, one of the trigger member 61 and the chip fixing seat 104b can be regarded as omitted.

[0174] In some embodiments, the ink cartridge 100 further includes a guide surface disposed on the cartridge body 1 for guiding the chip holder 104b upward. When the chip holder 104b directly or indirectly receives a force applied by the door cover PC, the chip holder 104b moves upward along the guide surface, that is, the electrical contact portion 104a1 moves from the electrically disconnected position to the electrically connected position. When the force is removed, the electrical contact portion 104a1 returns from the electrically connected position to the electrically disconnected position.

[0175] In some embodiments, as the door cover PC is closed, the force receiving portion 614 can also be pushed upward by the force applied by the door cover PC, that is, the force receiving portion 614 moves from the close position to the distant position. During the movement of the force receiving portion 614, the electrical contact portion 104a1 moves from the electrically disconnected position to the electrically connected position. When the force is withdrawn, the electrical contact portion 104a1 returns from the electrically connected position to the electrically disconnected position.

[0176] For example, the trigger member 61 is decomposed into multiple sections, the force received by the force receiving portion 614 is transmitted to the trigger portion 611 through the intermediate transmission portion between the force receiving portion 614 and the trigger portion 611, and the trigger portion 611 moves upward, and finally, the trigger portion 611 triggers the electrical contact portion 104a1 to move from the electrically disconnected position to the electrically connected position; or, the trigger member 61 is still formed in one piece, but there is at least a portion of deformable between the force receiving portion 614 and the rotating portion 615, that is, at least a portion of deformable portion is provided between the force receiving portion 614 and the rotating portion 615, and when the force receiving portion 614 receives the upward force, the deformable portion will roughly move toward Fig.23A The trigger portion 611 also moves upward through the rotating portion 615 , so that the electrical contact portion 104 a 1 moves from the electrical disconnection position to the electrical connection position.

[0177] Furthermore, during the closing process of the door cover PC, the chip component 104 / electrical contact portion 104a1 moves from bottom to top, thereby realizing the movement of the electric contact portion 104a1 from the electrically disconnected position to the electrically connected position, and during the installation process of the ink cartridge 100, the chip component 104 / electrical contact portion 104a1 is located in the electrically disconnected position, and even if the ink cartridge 100 is installed directly forward in a direction parallel to the front-to-back direction, the chip component 104 / electrical contact portion 104a1 will not interfere with the inner wall of the ink cartridge installation portion 300.

[0178] Compared with the existing ink cartridge which needs to be first tilted downward and rearward and then returned to a direction parallel to the front-to-back direction for installation, the ink cartridge 100 involved in this embodiment is not only simpler to install, but also will not cause ink leakage due to the tilt of the ink cartridge.

[0179] The above embodiments introduce a structure for forcing the electrical contact portion 104a1 in the chip component 104 to contact the contact pin 340 in the imaging device, and also introduce a structure in which the ink cartridge 100 is locked in the imaging device by a locking portion. Based on the introduction of the above embodiments, those skilled in the art may cross-combine the above embodiments according to actual design requirements.

[0180] Embodiments 9 to 12 of the present invention are described in detail below with reference to the accompanying drawings.

[0181] like Fig.24 , Fig.25A and Fig.25B As shown, along the up-down direction, the electric contact needle assembly 300b is located above the ink absorbing needle 310, and the electric contact needle assembly 300b at least includes the electric contact needle 340; along the up-down direction, the electric contact needle assembly 300b does not overlap with the ink absorbing needle 310, and the electric contact needle assembly 300b is located behind the ink absorbing needle 310 as a whole. In printers / imaging devices of different models, the relative position of the electric contact needle assembly 300b and the ink absorbing needle 310 may also change, and the corresponding structures of the ink cartridge 100 and the ink cartridge mounting portion 300 (such as the ink outlet portion 2 and the chip component 104 described later) may also undergo corresponding position changes. For example, along the up-down direction, at least a portion of the electric contact needle assembly 300b overlaps with the ink absorbing needle 310. For another example, along the up-down direction, the electric contact needle assembly 300b still does not overlap with the ink absorbing needle 310, but in the front-to-back direction, the electric contact needle assembly 300b is located in front of the ink absorbing needle 310.

[0182] Furthermore, each insertion space 350 is also provided with a color recognition component 200. Specifically, the color recognition component 200 has an recognition groove 201 and a first side 202. Further, the recognition groove 201 has openings facing rearward and in the up-down direction to allow the protruding component 3 to enter, and the first side 202 faces rearward. In each insertion space 350, the position of the recognition groove 201 of the color recognition component 200 in the left-right direction is different; in the up-down direction, the ink absorbing needle 310 is arranged at the lower end side of the insertion space 350 and is opposite to the ink cartridge mounting port 300a. The color recognition component 200 and the electric contact needle assembly 300b / electric contact needle 340 are both located on the upper end side of the insertion space 350. In the front-to-back direction, the color recognition component 200 is located on the front side of the electric contact needle assembly 300b / electric contact needle 340.

[0183] Furthermore, the insertion space 350 has a mounting portion front wall 350 a and a mounting portion bottom wall 350 b .

[0184] Furthermore, the insertion space 350 is also provided with a first interference surface / first interference portion 303a1, a second interference surface / second interference portion 303a2, a third interference surface / third interference portion 303a3 and a fourth interference surface / fourth interference portion 303a4. Specifically, the first interference surface / first interference portion 303a1, the second interference surface / second interference portion 303a2, the third interference surface / third interference portion 303a3 and the fourth interference surface / fourth interference portion 303a4 are all located above the insertion space 350. In the up and down direction, the third interference surface / third interference portion 303a3 is located above the second interference surface / second interference portion 303a2. Along the direction from back to front, the fourth interference surface / fourth interference portion 303a4, the first interference surface / first interference portion 303a1 and the second interference surface / second interference portion 303a2 are arranged in sequence.

[0185] [Example 9]

[0186] like Figure 26A-26C As shown, in the up and down direction, the ink outlet portion 2 is located at the lower side of the box body 1. In the present embodiment, further, an elastic seal (not shown) is provided in the ink outlet portion 2. The elastic seal is used to seal the ink outlet 21 before the ink cartridge 100 is installed to prevent ink leakage. When the ink cartridge 100 is installed toward the ink cartridge installation portion 300, the ink suction needle 310 enters the ink outlet 21 to cause the elastic seal to be elastically deformed, thereby opening the ink outlet 21 to allow ink to flow out of the ink outlet 21.

[0187] Further, such as Figure 26A-26C As shown, in the present embodiment, the lower side wall 100f is configured to be non-parallel to the front-to-back direction. For example, in the up-down direction, the front end portion 100f2 of the lower side wall 100f is located above the rear end portion 100f3. Specifically, in the up-down direction, the distance d2 between the rear end portion 100f3 and the axis / center line L2 of the ink outlet 21 is greater than the distance d1 between the front end portion 100f2 and the axis / center line L2 of the ink outlet 21. That is, the rear end portion 100f3 of the lower side wall 100f is configured to protrude downward. Such a design allows the front end portion 100f2 of the lower side wall 100f to not interfere with the ink cartridge installation portion 300 when the ink cartridge 100 is installed toward the ink cartridge installation portion 300, thereby allowing the ink cartridge 100 to be smoothly installed forward. In other embodiments, the lower side wall 100f may also be configured to be parallel to the front-to-back direction.

[0188] Furthermore, the ink cartridge 100 also includes a protruding component 3 and a chip component 104 arranged on the upper side of the box body 1. The protruding component 3 is used to be identified by the color recognition component 200. Specifically, the protruding component 3 is used to cooperate with the identification groove 201 of the color recognition component 200 so that the ink cartridge 100 can be smoothly installed in the insertion space 350. The chip component 104 is used to establish a communication connection between the ink cartridge 100 and the imaging device. Specifically, the chip component 104 includes a chip 104a and a coupling portion / chip fixing seat 104b that are coupled to each other. The coupling portion / chip fixing seat 104b is used to install the chip 104a. The coupling portion / chip fixing seat 104b is integrally / separately connected to the box body 1. In the present embodiment, the coupling portion / chip fixing seat 104b is configured to be integrally connected to the box body 1, that is, the chip 104a is directly disposed on the box body 1. The chip 104a includes a substrate 104a2 and an electrical contact portion 104a1 disposed on the substrate 104a2. Further, the electrical contact portion 104a1 is used to be electrically connected to the electrical contact pin 340.

[0189] Furthermore, in the present embodiment, the operating portion 105 is disposed on the rear side of the cartridge body 1, and the operating portion 105 can be used for installation and removal of the ink cartridge 100. Along the front-to-back direction, a groove 1053 is disposed in front of the operating portion 105, and the user can place a finger in the groove to apply force to the operating portion 105 to achieve installation and removal of the ink cartridge 100. In the up-down direction, the operating portion 105 is located on the upper side of the cartridge body 1, or in other words, the groove is disposed upward.

[0190] In one implementation, the operating portion 105 may also be configured as a groove structure that is recessed downward from the upper side wall 100e.

[0191] Furthermore, in the present embodiment, the ink cartridge 100 is also provided with a locking portion 4, which is used to lock the ink cartridge 100 after it is installed in the imaging device / ink cartridge installation portion 300. Specifically, the locking portion 4 includes an abutment portion 42, which is used to interact with components in the imaging device / ink cartridge installation portion 300 to lock the ink cartridge 100.

[0192] In this embodiment, if Fig.26AAs shown, the locking portion 4 / abutment portion 42 is arranged on the box body 1, and the locking portion 4 / abutment portion 42 is formed integrally with the box body 1, and the abutment portion 42 is provided with a locking surface 422, and the locking surface 422 is used to abut with the second interference surface / second interference portion 303a2 in the ink cartridge mounting portion 300 to generate friction, so that the ink cartridge 100 overcomes the force of withdrawing backward from the ink cartridge mounting portion 300, thereby locking the ink cartridge 100 in the ink cartridge mounting portion 300; the force that makes the ink cartridge 100 withdraw backward from the ink cartridge mounting portion 300 comes from, when the ink cartridge 100 is installed forward to the ink cartridge mounting portion 300, the ink suction needle 310 enters the ink outlet 21 and abuts against the elastic sealing component arranged in the ink outlet portion 2, and the elastic sealing component generates a backward thrust force, so that the ink cartridge 100 has a tendency to withdraw backward. Further, in the up-down direction, the locking surface 422 is located on the upper side of the box body 1, and the locking surface 422 is located above the operating portion 105. In the front-to-back direction, the locking surface 422 is located on the rear side of the box body 1; specifically, in the front-to-back direction, the locking surface 422 is located in front of the operating portion 105. When the ink cartridge 100 is locked, the locking surface 422 and the second interference surface / second interference portion 303a2 / acting member are in frictional contact with each other at the rear side of the box body 1. As can be seen from the accompanying drawings, in the front-to-back direction, the locking surface 422 is located behind the electric contact portion 104a1, and the second interference surface / second interference portion 303a2 / acting member is located behind the electric contact pin 340.

[0193] like Fig.27A and Fig.27B As shown, when the ink cartridge 100 is installed toward the ink cartridge mounting portion 300 / insertion space 350, the ink absorbing needle 310 enters the ink outlet 21 / ink outlet portion 2 and abuts against the elastic sealing member. As the ink cartridge 100 is further installed, the abutting portion 42 of the locking portion 4 begins to abut against the ink cartridge mounting portion 300. Specifically, the locking surface 422 of the abutting portion 42 begins to abut against the second interference surface / second interference portion 303a2 and generate friction. At the same time, the lower side wall 100f also abuts against the bottom wall 350b of the mounting portion and generates friction. When the ink cartridge 100 is installed to the predetermined position, the friction between the locking surface 422 and the second interference surface / second interference portion 303a2 and the friction between the lower side wall 100f and the bottom wall 350b of the mounting portion cause the ink cartridge 100 to be locked. At this time, the locking surface 422 / box body 1 is not in contact with the limiting member 320, that is, there is a gap between the locking surface 422 / box body 1 and the limiting member 320.

[0194] In the present embodiment, during the process of installing the ink cartridge 100 toward the ink cartridge installation portion 300, the first interference surface / first interference portion 303a1 can play a role in guiding the installation of the ink cartridge 100. Specifically, the first interference surface / first interference portion 303a1 is configured as a surface inclined along the front-to-back direction, and its inclination direction is such that, along the direction from front to back, the front end side of the first interference surface / first interference portion 303a1 is closer to the second interference surface / second interference portion 303a2 than the rear end side.

[0195] In one embodiment, when the ink cartridge 100 is installed to a predetermined position of the ink cartridge installation portion 300 / insertion space 350 , the locking surface 422 is located behind the stopper 320 in the front-to-back direction.

[0196] In one embodiment, when the ink cartridge 100 is installed to a predetermined position of the ink cartridge installation portion 300 / insertion space 350 , the locking surface 422 is located above or below the limiting member 320 in the up-down direction.

[0197] In one embodiment, the locking surface 422 can also abut against the first interference surface / first interference portion 303a1 or the third interference surface / third interference portion 303a3, for example, the friction between the locking surface 422 and the first interference surface / first interference portion 303a1 or the third interference surface / third interference portion 303a3 locks the ink cartridge 100.

[0198] Furthermore, as the ink cartridge 100 is installed toward the ink cartridge mounting portion 300, the front side wall 100c of the ink cartridge 100 serving as the limiting portion 1091 abuts against the mounting portion front wall 350a of the insertion space 350 to limit the forward displacement of the ink cartridge 100, thereby preventing the ink cartridge 100 from moving excessively forward and affecting the electrical contact between the chip 104a / electrical contact portion 104a1 and the electrical contact pin 340. The ink cartridge 100 is installed to a predetermined position.

[0199] Furthermore, in this embodiment, the ink cartridge 100 is locked through the friction between the locking surface 422 and the second interference surface / second interference portion 302a2 and the friction between the lower side wall 100f and the bottom wall 350b of the mounting portion, without the need for the ink cartridge 100 to be rotated downward and then locked. The elastic seal provided in the ink outlet portion 2 will not produce unnecessary deformation due to the downward rotation of the ink cartridge 100, thereby reducing the loss of the elastic seal, thereby reducing the performance requirements for the elastic seal and the cost of the elastic seal.

[0200] [Example 10]

[0201] The difference between this embodiment and the ninth embodiment is that the position where the ink cartridge 100 abuts against the ink cartridge installation portion 300 when being restricted forward is different, as described below.

[0202] like Fig.28A and Fig.28B As shown, as the ink cartridge 100 is installed toward the ink cartridge installation portion 300, the limiting portion 1091 provided on the cartridge body 1 abuts against the first side 202 of the color identification member 200 to limit the ink cartridge 100 from continuing to move forward, thereby preventing the ink cartridge 100 from moving forward excessively and affecting the electrical contact between the chip 104a / electrical contact portion 104a1 and the electrical contact pin 340, and the ink cartridge 100 is installed to a predetermined position.

[0203] The position and structure of the limiting portion 1091 do not need to be limited here, as long as the box body 1 / limiting portion 1091 can abut against the color recognition component 200 to limit the ink cartridge 100 from moving forward further.

[0204] [Example 11]

[0205] The difference between this embodiment and the above-mentioned ninth embodiment and tenth embodiment is that, in this embodiment, the combining portion / chip fixing seat 104b is separately connected to the box body 1, and the ink cartridge 100 is further provided with a trigger mechanism 6, as described below.

[0206] In this embodiment, the chip fixing seat 104b is configured to be movable relative to the box body 1 so that the electrical contact portion 104a1 can move between the electrically disconnected position and the electrically connected position. It can be realized that the chip fixing seat 104b is configured to rotate or translate relative to the box body 1. The chip fixing seat 104b shown in this embodiment is slidably configured relative to the box body 1.

[0207] When the ink cartridge 100 is installed toward the ink cartridge mounting portion 300 / insertion space 350, the trigger mechanism 6 is triggered, thereby forcing the chip fixing seat 104b to slide in the up and down directions, thereby forcing the chip 104a / electrical contact portion 104a1 to move from the electrically disconnected position to the electrically connected position. In the electrically disconnected position, the electrical contact portion 104a1 does not contact the electrical contact pin 340, and in the electrically connected position, the electrical contact portion 104a1 contacts the electrical contact pin 340; as the user operates the operating portion 105 located behind the ink cartridge 100, the ink cartridge 100 is gradually taken out of the ink cartridge mounting portion 300 / insertion space 350, the trigger mechanism 6 is gradually reset, and the chip 104a / electrical contact portion 104a1 returns from the electrically connected position to the electrically disconnected position. Therefore, the chip 104a / electrical contact portion 104a1 involved in this embodiment can move between the electrically disconnected position and the electrically connected position.

[0208] like Figure 29-Figure 31As shown, the chip fixing seat 104b is provided with a guided member 104b1, and the box body 1 is provided with a guiding member 107g for guiding the guided member 104b1. For example, the guided member 104b1 is set to be in a protrusion shape, and the guiding member 107g is set to be in a groove shape. The guiding groove 107g can extend in a direction parallel to the up and down direction, or can be set in an inclined direction inclined relative to the up and down direction, or can be set to be curved, but as a whole, the guiding groove 107g extends in the up and down direction; or, the guided member 104b1 is set to be in a groove shape, and the guiding member 107g is set to be in a protrusion shape.

[0209] In this embodiment, the trigger mechanism 6 is movably arranged relative to the box body 1, and the trigger mechanism 6 includes a trigger member 61, which is arranged to be movable between a protruding position and a trigger position. Before the ink cartridge 100 is installed, or before the trigger member 61 receives an external force, the trigger member 61 is located in the protruding position, and the chip 104a / electrical contact portion 104a1 is located in the electrically disconnected position; when the trigger member 61 receives an external force, the trigger member 61 moves from the protruding position to the trigger position, and the chip 104a / electrical contact portion 104a1 moves from the electrically disconnected position to the electrically connected position; when the trigger member 61 is located in the trigger position, the chip 104a / electrical contact portion 104a1 is located in the electrically connected position, at which time the chip 104a / electrical contact portion 104a1 can be kept in contact with the electrical contact pin 340 by the trigger member 61 or other components.

[0210] In one embodiment, a portion of the trigger member 61 is located in the accommodating cavity 107, and another portion of the trigger member 61 is located outside the accommodating cavity 107. In the up and down directions, the trigger member 61 exceeds the upper side wall 100e. This design can not only protect the trigger mechanism 6, but also reduce the size of the ink cartridge 100 in the up and down directions.

[0211] In one embodiment, the trigger mechanism 6 may also be completely located above the upper side wall 100e. In this case, the accommodating cavity 107 may not be required.

[0212] Specifically, the trigger member 61 has a force receiving surface / force receiving portion 614 for receiving external force and a force transmitting surface / force transmitting portion 612 for transmitting the force. The force receiving surface / force receiving portion 614 is used to abut against the second interference surface / second interference portion 303a2 in the cartridge mounting portion 300 / insertion space 350 to receive the external force, so that the trigger member 61 moves from the protruding position to the trigger position, and the force transmitting surface / force transmitting portion 612 is used to directly or indirectly transmit the force to the chip fixing seat 104b, so that the chip 104a / electrical contact portion 104a1 moves from the electrically disconnected position to the electrically connected position.

[0213] In one embodiment, the ink cartridge 100 is further provided with a retaining portion / retaining surface 613 for retaining the chip 104a / electrical contact portion 104a1 in an electrically connected position. Preferably, the retaining portion / retaining surface 613 is disposed on the trigger member 61, such as Fig.29 As shown, the force transmitting portion / force transmitting surface 612 and the retaining portion / retaining surface 613 are both arranged on the trigger portion 611 of the trigger member 61. Such an arrangement can simplify the structure of the trigger mechanism 6 / ink cartridge 100; along the front-to-back direction, the force receiving surface / force receiving portion 614 and the trigger portion 611 are respectively located at both ends of the trigger member 61.

[0214] In one embodiment, the trigger member 61 is configured as a movable rod that can rotate around the rotation axis L1. The extension direction of the rotation axis L1 does not need to be limited, as long as the trigger member 61 can be displaced in the up and down directions. Preferably, the rotation axis L1 extends in the left and right directions. In other embodiments, the rotation axis L1 can be configured to be inclined relative to the left and right directions.

[0215] Overall, the trigger member 61 in this embodiment is lever-shaped and has a rotating portion 615. The force receiving portion 614 and the trigger portion 611 are respectively located at both ends of the trigger member 61. Specifically, the force receiving portion 614 is provided with a force receiving surface 6141 for receiving external force. Preferably, before the ink cartridge 100 is installed, the force receiving surface 6141 is set to an inclined surface inclined relative to the front and rear directions, so as to facilitate smoother reception of external force.

[0216] Preferably, the second interference surface / second interference portion 303a2 is a certain component / group of components arranged in the ink cartridge installation portion 300. During the installation process of the ink cartridge 100, as long as the component can move the trigger member 61 from the protruding position to the trigger position, the second interference surface / second interference portion 303a2 can also be called an active member. For example, the active member is a protrusion arranged in the insertion space 350, or a color identification component 200 arranged in the insertion space 350.

[0217] In one embodiment, the first interference surface / first interference portion 303a1, the second interference surface / second interference portion 303a2, the third interference surface / third interference portion 303a3 and the fourth interference surface / fourth interference portion 303a4 can all be referred to as active members, which are located above the insertion space 350.

[0218] In one embodiment, the retaining portion / retaining surface 613 may not be set on the trigger member 61. For example, the retaining portion / retaining surface 613 is set as a component that is linked to the trigger mechanism 6. In the process of the trigger member 61 moving toward the trigger position, the retaining portion / retaining surface 613 gradually begins to contact the chip fixing seat 104b, so that the chip 104a / electrical contact portion 104a1 can be retained by the retaining portion / retaining surface 613; or, when the trigger member 61 reaches the trigger position, the chip fixing seat 104b is directly retained by the retaining portion / retaining surface 613.

[0219] In one embodiment, when the trigger member 61 is in the protruding position, the force transfer portion / force transfer surface 612 maintains contact with the chip fixing seat 104b. This design can improve the efficiency of force transmission on the one hand, and on the other hand, enable the chip 104a / electrical contact portion 104a1 in the electrically disconnected position to be stably supported.

[0220] like Fig. 30A , Fig. 30B and Fig.31 As shown, before the ink cartridge 100 is installed into the ink cartridge installation portion 300, or during the process of the ink cartridge 100 being installed toward the ink cartridge installation portion 300, the electrical contact portion 104a1 is located at the electrically disconnected position, the trigger member 61 is located at the protruding position, the lifted member 104b7 / 104b8 of the chip fixing seat 104b is supported by the trigger member 611, and the ink absorbing needle 310 is aligned with the ink outlet 21 along the front-to-back direction; as the ink cartridge 100 continues to be installed toward the ink cartridge installation portion 300, the ink absorbing needle 310 enters the ink outlet portion 2 through the ink outlet 21, and the force receiving surface 6141 / force receiving portion 614 begins to contact with the second interference surface / second interference portion 303a2, and the second interference surface / second interference portion 303a2 presses the force receiving surface 6141, and the force receiving surface 6141 / force receiving portion 614 and the second interference surface / second interference portion 303a2 press the force receiving surface The second interference surface / second interference portion 303a2 abuts and receives the external force, and gradually moves downward, so that the trigger member 61 rotates around the rotating portion 615 / rotation axis L1 in the direction r1, so that the force transmission surface / force transmission portion 612 pushes the lifted member 104b8 upward and pushes the chip fixing seat 104b to move upward, thereby causing the chip 104a / electrical contact portion 104a1 to move upward. According to the force, or under the action of the force, the trigger portion 611 / force transmission portion 612 pushes the chip fixing seat 104b / chip 104a / electrical contact portion 104a1 to move upward, and the trigger member 61 moves from the protruding position to the trigger position, thereby causing the chip 104a / electrical contact portion 104a1 to move from the electrically disconnected position to the electrically connected position.

[0221] like Fig. 30B and Fig.31As shown, when the ink cartridge 100 reaches the predetermined position, the trigger member 61 is located at the trigger position, the force receiving surface 6141 / force receiving portion 614 maintains abutment with the second interference surface / second interference portion 303a2, and the electrical contact portion 104a1 contacts the electrical contact pin 340. At the same time, the chip fixing seat 104b is supported by the retaining portion / retaining surface 613 so that the electrical contact portion 104a1 maintains stable contact with the electrical contact pin 340.

[0222] When the user applies a backward pulling force to the operating portion 105, the ink cartridge 100 begins to move backward, and the force receiving surface 6141 / force receiving portion 614 gradually disengages from the second interference surface / second interference portion 303a2. Under the action of gravity, the trigger member 61 rotates around the rotation axis L1 in a direction opposite to the direction r1, and the trigger member 61 begins to move from the trigger position toward the protruding position. At the same time, the chip fixing seat 104b begins to move from the electrically connected position to the electrically disconnected position with the chip 104a / electrical contact portion 104a1.

[0223] Furthermore, the accommodating cavity 107 has an exposure opening 1071 facing upward, and the trigger member 61 is disposed in the accommodating cavity 107 and exposed upward through the exposure opening 1071. Specifically, when the ink cartridge 100 is not installed in the ink cartridge installation portion 300, at least the force receiving portion 614 is located above the exposure opening 1071.

[0224] Furthermore, in the present embodiment, the locking portion 4 is arranged on the trigger member 61, and the force receiving portion 614 serves as the abutting portion 42 to abut against the ink cartridge mounting portion 300. Specifically, when the ink cartridge 100 is gradually installed toward the ink cartridge mounting portion 300, the force receiving surface 6141 serves as the locking surface 422 to gradually abut against the second interference surface / second interference portion 303a2, and through the friction force between the force receiving surface 6141 / locking surface 422 and the second interference surface / second interference portion 303a2, the ink cartridge 100 is locked and cannot withdraw backward from the ink cartridge mounting portion 300.

[0225] In one embodiment, the locking portion 4 can also be set on the ink cartridge 100. For example, the locking portion 4 is a protrusion set on the box body 1. Specifically, in the front-to-back direction, the locking portion 4 is located in front of the force receiving surface 6141, and the locking portion 4 is located behind the chip component 104. In this deformation mode, the trigger member 61 is pushed downward by the second interference surface / second interference portion 303a2 to make the trigger member 61 rotate along the direction r1, but no friction force is generated between the trigger member 61 and the second interference surface / second interference portion 303a2. Instead, friction force is generated between the protrusion / locking portion 4 and the second interference surface / second interference portion 303a2, so that the ink cartridge 100 is locked.

[0226] Furthermore, in the present embodiment, a limiting portion 1091 protruding upwardly on the rear side of the cartridge body 1 is used to abut against the ink cartridge mounting portion 300 to limit the forward displacement of the ink cartridge 100. Specifically, when the ink cartridge 100 is installed in the forward direction toward the ink cartridge mounting portion 300 / insertion space 350, a first limiting surface 10911 disposed forward in the limiting portion 1091 abuts against the fourth interference surface / fourth interference portion 303a4 of the ink cartridge mounting portion 300, thereby preventing the ink cartridge 100 from continuing to move forward and limiting the forward displacement of the ink cartridge 100, thereby preventing the ink cartridge 100 from moving excessively forward and affecting the electrical contact between the chip 104a / electrical contact portion 104a1 and the electrical contact pin 340.

[0227] In one embodiment, the lower side wall 100f of the cartridge body 1 is provided with a locking portion 1092, and the locking portion 1092 is used to engage with a groove portion provided in the bottom wall 350b of the mounting portion, so that the ink cartridge 100 is locked.

[0228] [Example 12]

[0229] Fig.32 It is a schematic diagram of the state of the ink cartridge involved in the twelfth embodiment of the present invention after being installed in the ink cartridge installation part.

[0230] The difference between this embodiment and the eleventh embodiment is that the locking position of the ink cartridge 100 is different, as described below.

[0231] like Fig.32 As shown, in this embodiment, when the ink cartridge 100 is installed toward the ink cartridge installation portion 300, the second limiting surface 10912 of the limiting portion 1091 arranged upward acts as a locking surface 422 and gradually abuts against the third interference surface / third interference portion 303a3. As the ink cartridge 100 is further installed forward, the friction force between the second limiting surface 10912 and the third interference surface / third interference portion 303a3 causes the ink cartridge 100 to be locked.
