In the front-to-back direction, the first end 110g extends forward from the air guide rod body 110a1 and is used to abut against the sealing member 110d, so that the sealing member 110d seals the air guide port 110b. The air guide component 110 / air guide rod 110a can move from a sealing position to an unsealing position, wherein the sealing position, i.e., the air guide port 110b is sealed by the sealing member 110d, and the ink cavity 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 cavity 106 is connected to the atmosphere.

[0076] Optionally, the sealing member 110d is generally constructed as an elastic member, and the size of the sealing member 110d is slightly larger than the size of the air guide port 110b.

[0077] Optionally, the ink cartridge 100 may also be provided with a retaining member for retaining the sealing member 110d. When the air guide member 110 moves toward the unsealing position, the first end portion 110g no longer abuts against the sealing member 110d. At this time, the air guide port 110b is no longer sealed, and the sealing member 110d is retained by the retaining member so that the first end portion 110g can accurately abut against the sealing member 110d again.

[0078] In some embodiments, the first end portion 110g is constructed to be cylindrical. When the radial dimension of the first end portion 110g is slightly larger than the air port 110b, the first end portion 110g does not enter the air port 110b, and the air port 110b is sealed by squeezing the seal 110d by the first end portion 110g. Further, the seal 110d can be constructed as a part of the first end portion 110g. In other words, the ink cartridge 100 is no longer provided with the seal 110d, and the air port 110b is sealed by squeezing the first end portion 110g on the third partition 107m3 described below.

[0079] In some embodiments, the front end of the first end 110g is constructed to be conical, and at least a portion of the seal 110d can enter the air port 110b along with the first end 110g, so that the air port 110b is sealed by the seal 110d. Compared with the sealing method in which the seal 110d does not enter the air port 110b, the extrusion force required for the seal 110d to enter the air port 110b is reduced.

[0080] Optionally, in the front-to-back direction, the sealing member 110d is located in front of the guide plate 107m2, so that the air guide port 110b can be quickly sealed by the sealing member 110d.

[0081] The air guide component 110 is also provided with at least an abutting portion 110f for abutting against the extension portion 104b3. In the up and down direction, the uppermost side of the abutting portion 110f is located above the upper side wall 100e; specifically, the abutting portion 110f has at least a front surface 110f1 facing forward and a rear surface 110f2 facing rearward, at least a portion of the front surface 110f1 is used to abut against the imaging device, and at least a portion of the rear surface 110f2 is used to abut against the extension portion 104b3; optionally, the abutting portion 110f is constructed to extend upward from the second end portion 110h, and in some embodiments, the abutting portion 110f can also be constructed to extend upward from the air guide rod body 110a1.

[0082] Preferably, when the electrical contact portion 104a1 is in the electrically disconnected position, in the up and down directions, the upper end of the abutment portion 110f is located above the upper end of the electrical contact portion 104a1, or in other words, the abutment portion 110f is higher than the electrical contact portion 104a1. The abutment portion 110f arranged in this way can effectively protect the electrical contact portion 104a.

[0083] Optionally, the air guiding component 110 also has a reset member, which can be used to move the air guiding component 110 / air guiding rod 110a toward the sealing position. Optionally, the reset member is located between the air guiding rod body 110a1 and the step surface 107m1, or, the reset member is located between the air guiding rod body 110a1 and the first partition plate 107a1. Preferably, the reset member is an elastic member.

[0084] In some embodiments, according to the required moving distance of the air guide rod 110a in the front-to-back direction, or according to the required moving distance of the electrical contact portion 104a1 of the chip component 104 in the up-down direction, the tightness of the electrical connection between the electrical contact portion 104a1 and the electrical contact pin 340 is controlled. For this purpose, the front surface 110f1 can also be set to be parallel to the up-down direction, or the front surface 110f1 can be set to be inclined forward / backward.

[0085] (Atmospheric path and ink chamber)

[0086] When the air guide member 110 / air guide rod 110a is located in the unsealing position, the ink chamber 106 is connected to the atmosphere to keep the pressure in the ink chamber 106 stable; optionally, the ink cartridge 100 is also provided with an atmospheric path 120 (gas circulation channel 140) connected to the air guide port 110b, and the atmospheric path 120 is used to connect the ink chamber 106 and the air guide port 110b. Preferably, the atmospheric path 120 is constructed into at least three sections. Specifically, at least a part of the first section 122 of the atmospheric path 120 (hereinafter referred to as the "first section 122") is located in the first accommodating chamber 107m, and the second section 123 of the atmospheric path 120 (hereinafter referred to as the "second section 123") is located between the first partition plate 107a1 and the ink chamber 106. The third section 124 of the diameter 120 (hereinafter referred to as the "third section 124") is located between the fourth partition plate 107a2 and the ink chamber 106, and the second section 123 is used to connect the first section 122 and the third section 124. The third section 124 is connected to the ink chamber 106. Along the up and down direction or the front and back direction of the ink cartridge 100, the first section 122 and the third section 124 are respectively located at the two ends of the ink chamber 106. Preferably, at least one of the first section 122 and the third section 124 can be constructed as a curved maze shape, and the second section 123 can be constructed as a long and narrow pipe shape. Generally, the maze-like path occupies a larger space. Setting the atmospheric path in this way can not only extend the flow path of the atmosphere and slow down the flow speed of the atmosphere, but also make full use of the space in the ink cartridge 100.

[0087] Optionally, a buffer zone 121 (i.e., the gas buffer zone 141 described below) is provided between the first section 122 and the third partition plate 107m3. The buffer zone 121 is at least used to install a buffer component, such as a sponge. The buffer component can both filter the air and slow down the air flow rate. Furthermore, the buffer component can also prevent the ink from flowing back. Furthermore, the buffer component can form a certain negative pressure in the ink chamber 106.

[0088] In this embodiment, the ink chamber 106 of the ink cartridge 100 is divided into multiple interconnected cavities by multiple side panels. This arrangement can make the box body 1 more universal. In the actual production process of the ink cartridge 100, the factory can select the capacity of the ink chamber 106 according to the model of the ink cartridge 100 produced. When it is necessary to produce a large-capacity ink cartridge 100, all the cavities can be connected. When it is necessary to produce a small-capacity ink cartridge 100, some of the cavities can be closed.

[0089] (Installation of Ink Cartridge 100)

[0090] In this embodiment, Figure 5As shown, when the ink cartridge 100 is in an initial state where it is not installed, the air guide component 110 / air guide rod 110a is located in a sealing position, specifically, the rear surface 110f2 of the abutting portion 110f abuts against the extending portion 104b3 of the chip component 104, and the air guide port 110b is sealed by the sealing member 110d; the electrical contact portion 104a1 is located in an electrically disconnected position, that is, the electrical contact portion 104a1 does not form an electrical connection with the electrical contact pin 340.

[0091] When the ink cartridge 100 is installed along the installation direction, as shown in FIG. Figure 6 and Figure 7 As shown, the air guide member 110 is triggered by the action member, and the air guide member 110 / air guide rod 110a moves from the sealing position to the unsealing position. Specifically, the action member abuts against the front surface 110f1 of the abutting portion 110f and forces the air guide member 110 to move backward, and the first end 110g moves backward, resulting in the sealing member 110d no longer being abutted by the first end 110g, and the sealing of the air guide port 110b is released, and the rear surface 110f2 of the abutting portion 110f is still abutted against the extension portion 104b3 of the chip member. The extension portion 104b3 receives the thrust from the abutment portion 110f, forcing the chip holder body 104b to move backward, and the connecting member 104c undergoes elastic deformation. Under the action of the lifting assembly, the chip holder body 104b simultaneously rotates upward around the sliding portion 104b1. When the ink cartridge 100 reaches the installation state, the electrical contact portion 104a1 reaches the electrical connection position to form an electrical connection with the electrical contact pin 340; through the abutment of the front surface 110f1 with the acting member, the electrical connection between the electrical contact portion 104a1 and the electrical contact pin 340 is maintained.

[0092] (Resetting the ink cartridge 100)

[0093] When the ink cartridge 100 moves backward and is taken out, the air guide component 110 / air guide rod 110a moves from the unsealing position to the sealing position. Specifically, the front surface 110f1 of the abutment portion 110f gradually loses contact with the action member, the electrical contact portion 104a1 loses electrical connection with the electrical contact pin 340 and reaches the electrical disconnection position, the connector 104c releases the elastic force to force the chip fixing seat 104b to rotate downward, the extension portion 104b3 of the chip component 104 and the rear surface 110f2 of the abutment portion 110f abut and force the air guide component 110 to move forward until the air port 110b is sealed by the sealing member 110d, and the air guide component 110 / air guide rod 110a reaches the sealing position.

[0094] In some embodiments, the air guide component 110 may also be provided with an elastic member, which is used to force the air guide rod 110a to move toward the sealing position; in the process of the ink cartridge 100 moving from the initial state to the installation state, when the front surface 110f1 abuts against the active member, the air guide rod 110a moves backward from the sealing position to the unsealing position, and the elastic member undergoes elastic deformation. At the same time, through the abutment of the rear surface 110f2 with the extension portion 104b3, the chip seat body 104b also moves backward and rotates upward around the sliding portion 104b1, and the connecting member 104c undergoes elastic deformation; in the process of the ink cartridge moving from the installation state to the initial state, when the front surface 110f1 is disengaged from the abutment with the active member, the connecting member 104c releases the elastic force, forcing the chip seat body 104b to move forward and rotate downward around the sliding portion 104b1. At the same time, the elastic member also releases the elastic force, forcing the air guide rod 110a to move forward from the unsealing position to the sealing position.

[0095] When the elastic member is provided in the air guide component 110, when the ink cartridge 100 is in the initial state, the rear surface 110f2 of the air guide component 110 may not abut against the extension portion 104b3, and the rear surface abuts against the extension portion 104b3 only when the air guide rod 110a moves backward. This can prevent the front surface 110f1 from being accidentally hit, causing the chip fixing seat 104b to rotate upward, thereby damaging the electrical contact portion 104a1.

[0096] In this embodiment, first, when the ink cartridge 100 is in the initial state, in the up and down direction, the upper end of the abutment portion 110f is located above the electrical contact portion 104a1. Such arrangement of the abutment portion 110f can effectively protect the electrical contact portion 104a1. When the ink cartridge 100 falls or is hit, the abutment portion 110f can be collided first, thereby protecting the electrical contact portion 104a1.

[0097] Second, the ink cartridge 100 is provided with an air guide component 110, which can be triggered as the ink cartridge 100 is installed, so that the air guide component 110 moves from the sealing position to the unsealing position, and the air guide port 110b is automatically opened without manual operation by the user, thereby improving the user experience.

[0098] Third, when the air guide port 110b of the ink cartridge 100 is opened, the chip component 104 is driven by the air guide component 110 to move upward, the electrical contact portion 104a1 forms an electrical connection with the electrical contact pin 340, and the extension portion 104b3 of the chip component 104 is always in contact with the abutment portion 110f of the air guide component 110. This arrangement can, on the one hand, enhance the stability of the electrical connection between the electrical contact portion 104a1 and the electrical contact pin 340, and on the other hand, can also reduce the number of components of the ink cartridge 100 and simplify the structure of the ink cartridge 100.

In the up and down direction, the extension portion 104b3 is used to abut against the front end of the sub-upper side wall 100e1, so as to ensure that the chip fixing seat 104b will not fall off from the ink cartridge 100.

[0105] In the electrically disconnected position, due to the gravity of the chip fixing seat 104b, in the up and down directions, the first part 1321 approaches the fourth partition 107a2 and contacts the fourth partition 107a2; in the electrically connected position, as the ink cartridge 100 is installed to the ink cartridge mounting portion 300 along the installation direction, the front end of the electric contact portion 370 abuts against the second part 1322, the second part 1322 moves backward, the guide assembly 130 pivots backward around the connecting portion 131, and the first part 1321 moves upward, so that the chip fixing seat 104b also moves upward, and further, the electric contact portion 104a1 forms an electrical connection with the electric contact pin 340.

[0106] The air guide port 110b is arranged on the first partition plate 107a1 / the fourth partition plate 107a2, and the air guide port 110b is connected with the first accommodating chamber 107m / the second accommodating chamber 107n.

The sealing silicone 107a4 is also provided with through holes corresponding to the air guide port 110b, the first air inlet 110b1 and the second air inlet 110b2, respectively. In the up and down directions, the through holes on the sealing silicone 107a4 overlap with the air guide port 110b, the first air inlet 110b1 and the second air inlet 110b2, respectively.

[0110] The ink cartridge includes a first box side wall 100e3 located between the upper side wall 100e and the first partition plate 107a1. The ink cartridge 100 also has an extension wall 100e4 extending rearward from the first box side wall 100e3. A portion of the seal 110d is located below the extension wall 100e4, thereby limiting the movement of the seal 110d in the up and down directions. The ink cartridge 100 has a first protrusion 100e5 protruding downward from the downward surface of the extension wall 100e4. The first protrusion 100e5 is used to abut against the seal 110d, so that the seal 110d is maintained in a sealed position, limiting the movement of the seal 110d in the front and rear directions.

[0111] The first accommodating chamber 107m includes a limiting groove for accommodating the sealing member 110d, and the limiting groove is formed by at least one of the first box side wall 100e3 and the step surface 107m1, and the first partition plate 107a, and at least one of the left side wall 100a and the right side wall 100b, so as to limit the movement of the sealing member 110d in the left and right directions.

The eighth groove 110k1 cooperates with the fourth protrusion 107a6 to fix the abutting portion 110f. At this time, the abutting portion 110f will not exert a downward force on the sealing member 110d.

[0125] In this embodiment, the first guide portion 110i and the second guide portion 110j are used to guide the abutment portion 110f, and the first guide portion 110i and the second guide portion 110j are configured to be in an inverted "L" shape. When the sealing member 110d is located at the sealing position, the second protrusion 110d5 and the third protrusion 110d6 are respectively located at the front end of the first guide portion 110i and the front end of the second guide portion 110j, so that the pressing member 110d is supported by the box body 1; when the sealing member 110d is located at the unsealing position, the abutment portion 110f moves backward under the action of external force, disconnects from the fourth protrusion 107a6, and causes the sealing member 110d to move downward.

[0126] like Fig.15 and Fig.16 As shown, when the seal 110d is in the sealing position, the third action portion 110d10 seals at least one of the first air inlet 110b1 and the second air inlet 110b2, the abutment portion 110f is limited by the fourth protrusion 107a6, the abutment portion 110f is located above the air guide port 110b, the second protrusion 110d5 and the third protrusion 110d6 are respectively located in the first guide portion 110i and the second guide portion 11, the air guide port 110b is connected to the atmosphere, and the inside of the gas circulation channel 140 is not connected to the atmosphere. At this time, the abutment portion 110f is located above the seal 110d, but will not apply a force to the seal 110d, and the ink cavity 106 is not connected to the gas circulation channel 140.

[0127] In some embodiments, another communication channel may be provided on the sealing body 110d7, and the atmosphere enters the communication channel from the first air inlet 110b1 and then enters the second air inlet 110b2 from the communication channel.

The first and second air inlet ports 110b1 and 110b2 are offset, and the first and second air inlet ports 110b1 and 110b2 are no longer sealed and are connected to the gas circulation channel 140. At this time, the sealing member 110d is located in the unsealing position, and the gas reaches the ink chamber 106 via the air guide port 110b, the first connecting port 142, the first air inlet port 110b1, the receiving groove 107a5, the second air inlet port 110b2 and the second connecting port 143, and the ink chamber 106 is connected to the atmosphere.

[0129] In the second and third embodiments, the sealing member 110d can be moved from the unsealing position to the sealing position along the front-to-back direction, so that when the ink cartridge 100 is vacuum-packed, the sealing member 110d will not be accidentally opened under the vacuum suction.

[0130] [Example 4]

[0133] In some embodiments, the abutment portion 110f may also abut against the second side wall 382 of the device or the third side wall 383 of the device.

[0134] like Fig.19 and Fig. 20 As shown, the receiving groove 107a5 is formed by being recessed downward from the fourth partition plate 107a2, and the air guide port 110b is disposed on the fourth partition plate 107a2 and is located near the receiving groove 107a5.

[0135] A fourth through hole 1323 is provided on the first portion 1321 of the second guide member 132, a bearing platform 1324 is provided in the fourth through hole 1323, the first action portion 110d8 is located above the bearing platform 1324 and abuts against the bearing platform 1324, and the first action portion 110d8 can move in the up and down direction together with the second guide member 132.

[0136] Along the installation direction of the ink cartridge 100, the force-applying portion is located behind the stylus seat 370. As the ink cartridge 100 is installed toward the ink cartridge installation portion 300 along the installation direction, the first side wall 381 of the device abuts against the second portion 1322, the second portion 1322 moves backward, the guide assembly 130 pivots backward around the connecting portion 131, the first portion 1321 moves upward, and drives the first action portion 110d8 / seal 110d to move upward together, the first air inlet 110b1 and the second air inlet 110b2 move upward together, and the first air inlet 110b2 moves upward together with the first air inlet 110b3. 110b2 is no longer sealed by the third action part 110d10, the air guide port 110b is connected to the atmosphere, the third action part 110d10 moves upward, the first air inlet 110b1 and the second air inlet 110b2 are no longer sealed, and are connected to the gas circulation channel 140, and the gas reaches the ink chamber 106 via the air guide port 110b, the first connecting port 142, the first air inlet 110b1, the second air inlet 110b2 and the second connecting port 143, and the ink chamber 106 is connected to the atmosphere.

Preferably, a second action portion 110d9 is also provided on the seal 110d, and the support platform 1324 is located between the first action portion 110d8 and the second action portion 110d9. When the second guide member 132 is reset, the support platform 1324 presses the second action portion 110d9 to return the seal 110d to the sealing position.

[0138] In some embodiments, the seal 110d can also be disposed behind the connecting portion 131, and when the second guide 132 is not acted upon by external force, the atmosphere connecting piece is sealed by the seal 110d; when the second guide 132 pivots under the action of external force, the seal 110d is pressed downward, the seal 110d moves downward, the atmosphere connecting piece is opened, and the ink chamber 106 is connected to the atmosphere.

[0139] During the process of installing the ink cartridge in the ink cartridge installation part 300 along the installation direction, the seal 110d directly or indirectly interacts with the components in the ink cartridge installation part 300 and moves relative to the box body 1, so that the seal 110d can at least move from the sealing position to the unsealing position. During this process, the ink chamber 106 can be connected to the atmosphere without the user manually operating the seal 110d.

[0140] During the process of installing the ink cartridge 100 provided in Example 2, Example 3 and Example 4 into the ink cartridge installation portion 300 along the installation direction, the seal 110d directly or indirectly interacts with the components in the ink cartridge installation portion 300 and moves relative to the cartridge body 1, so that the seal 110d can at least move from the sealing position to the unsealing position. During this process, the ink chamber 106 can be connected to the atmosphere without the user manually operating the seal 110d.

[0141] [Example 5]

[0142] like Fig.21A and 21B As shown, in this embodiment, the ink cartridge installation portion 300 has the same direction as the ink cartridge 100, including a mounting frame 301 and a plurality of side panels 302, the mounting frame 301 having an ink cartridge installation port 300a open toward the rear, the insertion space 350 is formed between the side panel 302 and the mounting frame 301 and between two adjacent side panels 302, each insertion space 350 is provided with an ink absorbent needle 310, a limiter 320 and an electric contact needle assembly 300b, and the ink cartridge 100 is installed from the ink cartridge installation port 300a toward the ink cartridge installation portion 300.

[0143] 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.

[0144] like Fig. 22 As shown, in this embodiment, the ink cartridge 100 further includes a locking portion 4 for locking the ink cartridge 100 in the imaging device / ink cartridge installation portion, 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 locking position and an unlocking position relative to the cartridge body 1, the fourth reset member 47 is used to force the abutting portion 42 to move toward the locking 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, the electrical contact portion 104a1 is located in the electrical connection position, and in the unlocking 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 installation portion 300 / insertion space 350, such as the first protrusion 300d or the second protrusion 300e.

[0145] In one embodiment, a portion of the fourth restoring member 47 and a portion of the abutting portion 42 are both located in the accommodating cavity 107 , which helps the abutting portion 42 maintain a stable motion trajectory.

[0146] 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.

[0147] 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.

[0148] like Fig.23 As 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 squeezed 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. The extrusion surface 421 is squeezed by the first protrusion 300d again, and the abutment portion 42 overcomes the restoring force of the fourth restoring member 47 and moves downward again. The abutment 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 abutment 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 / abutment portion 42 abuts against the first protrusion 300d. The abutment portion is located in the locked position, and the ink cartridge 100 is locked in the imaging device.

[0149] like Fig.24 and Fig.25 As shown, the locking portion 4 is configured as a cantilever located 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 / ink cartridge installation portion 300 / insertion space 350, after the extrusion surface 421 abuts against the electric contact needle assembly 300b, at least a portion of the abutting portion 42 is elastically deformed downward until the abutting portion 42 passes over the blocking portion, or in other words, the abutting portion 42 reaches the front of the blocking portion, the extrusion surface 421 is disengaged from the blocking portion, the abutting portion 42 no longer undergoes elastic deformation, the locking surface 422 abuts against the front surface of the electric contact needle assembly 300b, and the ink cartridge 100 is locked.

[0150] In the above process, after the abutment portion 42 passes over the blocking portion, at this time, the sealing member 110d abuts against the ink cartridge mounting 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. The air guide port 110b opens, and the abutment 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.

[0151] 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.

[0152] 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.

[0153] [Example 6]

[0154] like Fig.26 and Fig. 27 As shown, a color recognition component 200 is also provided in each insertion space 350 of the ink cartridge installation portion, and the color recognition component 200 and the electric contact needle 340 are both arranged above the ink absorber needle 310; the color recognition component 200 includes an identification groove 201 opening downward and backward; the identification groove 201 is used to allow the following raised component 3 to enter; the ink absorber needle 310 is arranged below the insertion space 350, opposite to the ink cartridge installation port 300a.

[0155] like Fig.28 and Fig.29 As shown, the accommodating chamber 107 is used to accommodate at least a portion of the trigger mechanism 6; a first partition 107a (middle partition 107a) is provided between the ink chamber 106 and the accommodating chamber 107, and the first partition 107a is used to separate the ink chamber 106 from the accommodating chamber 107.

[0156] Furthermore, the ink cartridge 100 further comprises a protruding member 3 movably arranged relative to the box body, and the protruding member 3 can move between an initial position and a mating position relative to the box body 1; in the initial position, as viewed along the front-to-back direction, at least a portion of the identification groove 201 does not overlap with the protruding member 3, in other words, the protruding member 3 cannot enter the color identification member 200; in the mating position, as viewed along the front-to-back direction, the identification groove 201 overlaps with the protruding member 3, in other words, the protruding member 3 can enter the color identification member 200; a portion of the protruding member 3 is arranged in the accommodating cavity 107, and another portion is exposed above the box body 1 / upper side wall 100e; in this embodiment, in the ink cartridge 100 for accommodating inks of different colors, the distance from the portion of the protruding member 3 exposed to the upper side wall 100e to the left side wall 100a or the right side wall 100 of the box body is the same, that is, the initial position of the protruding member 3 in the ink cartridge 100 for accommodating inks of different colors is the same, and thus, the ink cartridge 100 involved in the present invention can be universal. In some embodiments, the protruding member 3 is also used to be detected by a light detection member provided in the imaging device, which includes a light emitting element and a light receiving element; accordingly, in the initial position, the protruding member 3 does not block the light emitted by the light emitting element, and the light receiving element can receive the light; in the mating position, the protruding member 3 blocks the light emitted by the light emitting element, and the light receiving element cannot receive the light.

[0157] Furthermore, at least a portion of the chip component 104 is disposed above the first shell 101 a and behind the protruding component 3 .

[0158] Furthermore, the ink cartridge 100 also includes a first through portion 100g arranged on the box body 1, and the first through portion 100g is used to avoid the protruding member 3 so that the protruding member 3 can be exposed to the box body 1. Preferably, the first through portion 100g penetrates the upper side wall 100e, so that the protruding member 3 can pass through the upper side wall 100e through the first through portion 100g; in the front-to-back direction, the first through portion 100g is located in front of the handle 105.

[0159] Furthermore, the ink cartridge 100 is also provided with a trigger mechanism 6 for forcing the protruding member 3 to move to the mating position. The trigger mechanism 6 is configured to be triggered by a certain component / group of components in the ink cartridge accommodating portion and move between the protruding position and the trigger position. When the trigger mechanism 6 is in the protruding position, the protruding member 3 is in the initial position; when the trigger mechanism 6 is in the trigger position, the protruding member 3 is triggered by the trigger mechanism 6 to move toward the initial position or remain in the mating position.

[0160] Furthermore, the ink cartridge 100 also includes a conversion mechanism 4 arranged between the trigger mechanism 6 and the protruding member 3, and the conversion mechanism 4 responds to the movement of the trigger mechanism 6 to move the protruding member 3 from the initial position to the mating position; the conversion mechanism 4 includes an active member 4a and a driven member 4b that act on each other, and the active member 4a and the driven member 4b cooperate with each other to realize the transmission and conversion of the force.

[0161] Furthermore, the ink cartridge 100 also includes a third through portion 100h arranged on the first shell 101a, and the third through portion 100h is used to allow a part of the trigger mechanism 6 to be exposed to the outside of the ink cartridge 100 so that the trigger mechanism 6 is in a protruding position. The third through portion 100h is connected to the accommodating cavity 107.

[0162] like Fig.28 , Fig.29 and Fig.30 As shown, the protruding member 3 includes a main body 35 and a supporting portion 34 that are connected to each other; the main body 35 extends in the front-to-rear direction of the box body 1, and at least a portion of the main body 35 is used to cooperate with the identification groove 201 in the ink cartridge identification member 200; the supporting portion 34 is used to support the main body 35 and enable the protruding member 3 to be installed on the box body 1.

[0163] The trigger mechanism 6 includes a trigger member 6a and a reset member 6b. The trigger member 6a is triggered by an action member (e.g., a color recognition member 200) outside the ink cartridge to move the protruding member 3 between the initial position and the mating position. For example, the action member is a member disposed in the ink cartridge mounting portion 300. Under the action of the action member, the trigger member 6a moves between the protruding position and the trigger position. In the protruding position, the trigger member 6a can pass through the third through portion 100h and be partially exposed to the outside of the cartridge body 1. In the trigger position, the trigger member 6a is triggered by the action member and partially retracted into the accommodating cavity. It is understood that when the trigger member 6a begins to interact with the action member, the trigger member 6a is in the trigger position, and when the trigger member 6a forces the protruding member 3 to the mating position, the trigger member 6a is in the trigger completion position; the reset member 6b is used to force the trigger member 6a to reset; in the present embodiment, the reset member 6b is arranged between the trigger member 6a and the side wall of the accommodating cavity 107, and is used to apply an elastic force in the front-to-back direction to the trigger member 6a; in some embodiments, the reset member 6b can also apply an elastic force intersecting with the front-to-back direction, so that the protruding member 3 maintains a tendency to move toward the initial position.

[0164] The first through portion 100g extends along the left-right direction on the upper side wall 100e of the box body 1, and is at least used to limit the movement of the protruding member 3 in the left-right direction relative to the side wall / box body 1; at the same time, the first through portion 100g can also guide the movement direction of the protruding member 3 in the left-right direction; specifically, at least one first through portion 100g is set.

[0165] The protruding component 3 interacts with the trigger mechanism 6 through the conversion mechanism 4; specifically, the conversion mechanism 4 includes an active member 4a and a driven member 4b that cooperate with each other, the active member 4a is arranged on the trigger member 6a, and the driven member 4b is arranged on the protruding component 3. Through the cooperation of the active member 4a and the driven member 4b, the force received by the trigger member 6a from the action member can be transmitted to the protruding component 3.

[0166] In this embodiment, the active member 4a is configured as a slide groove, the extension direction of the slide groove is perpendicular to the up-down direction, and is inclined relative to the left-right direction and the front-back direction, and the driven part 4b is configured as a protrusion that cooperates with the slide groove, so that the active member 4a transfers the force received by the trigger member 6a to the driven member 4b; in some embodiments, the setting positions of the active member 4a and the driven member 4b can also be interchanged, that is, the slide groove is set on the protruding member 3, and the protrusion is set on the trigger member 6a; the number of the active member 4a and the driven member 4b is at least one.

[0167] When the protruding member 3 moves between the initial position and the mating position, it is restricted by at least one of the first through portion 100g and the active member 4a; when the inclination angle of the slide groove relative to the left and right directions is larger, the moving distance of the protruding member 3 pushed by the conversion mechanism 4 is smaller. Therefore, the ink cartridge 100 for accommodating inks of different colors can adopt slide grooves with different inclination angles to ensure that the protruding member 3 in each ink cartridge 100 can enter the corresponding identification groove 201.

[0168] Installation process of the ink cartridge 100: When the ink cartridge 100 is in the initial state, the protruding member 3 is located at the initial position, the trigger member 6a is located at the protruding position, and the main body 35 does not cooperate with the color identification member 200; in the process of installing the ink cartridge 100 into the insertion space 350 in the forward direction, the trigger member 6a abuts against the action member and is triggered by the action member, and the trigger member 6a is moved from the protruding position to the trigger position by the backward triggering force, and the triggering force from front to back is converted into a force forcing the protruding member 3 to move in the left and right direction through the conversion mechanism 4; the protruding member 3 receives the triggering force, moves from the initial position to the matching position, and finally reaches the matching position, at which time the trigger member 6a enters the identification groove 201; in the above process, the reset member 6b undergoes elastic deformation and accumulates elastic force.

[0169] The removal process of the ink cartridge 100: when the ink cartridge 100 is in the installed state, the protruding member 3 is located in the mating position, and the main body 35 is located in the identification groove 201; in the process of removing the ink cartridge 100 from the insertion space 350 in the backward direction, the trigger member 6a gradually disengages from the abutment with the action member, and the reset member 6b releases the stored elastic force, so that the trigger member 6a is subjected to the forward reset force, thereby moving from the trigger position to the protruding position; at the same time, through the conversion mechanism 4, the reset force from back to front applied by the reset member 6b is converted into a force that forces the protruding member 3 to reset in the left-right direction, thereby, the protruding member 3 moves in the left-right direction from the mating position to the initial position, and finally reaches the initial position, and the trigger mechanism 6 and the protruding member 3 are both reset.

[0170] In some embodiments, the reset member 6b can also be configured to abut against the raised member 3. During the removal of the ink cartridge 100, the reset member 6b moves in the left and right directions by forcing the raised member 3, and through the conversion mechanism 4, the raised member 3 pushes the trigger member 6a to reset.

[0171] In some embodiments, the moving distance of the raised member 3 in the left and right directions can be controlled by adjusting parameters such as the extended length of the trigger member 6a and the inclination angle of the active member 4a. That is, the raised member 3 in the ink cartridge for accommodating inks of different colors can produce different displacements in the left and right directions in the above manner, thereby ensuring that the raised members 3 of the ink cartridges of different colors can all enter the identification slot 201 in the corresponding color insertion space 350.

[0172] [Example 7]

[0173] like Fig.31 and Fig.32 As shown, based on the sixth embodiment, the conversion mechanism in this embodiment is different from that in the sixth embodiment.

[0174] Specifically, in the present embodiment, the active member 4a is arranged on the trigger member 6a, and the driven member 4b is arranged on the protruding member 3; the trigger member 6a still protrudes in front of the box body 1; preferably, the active member 4a is arranged at the rear end of the trigger member 6a, and is provided with an arc surface protruding backward from the trigger member 6a; the driven member 4b is arranged in front of the support portion 34, and is provided with an inclined surface inclined relative to the left and right directions.

[0175] In some embodiments, the positions of the active member 4a and the driven member 4b can be interchanged, that is, the convex arc surface is disposed on the protruding member 3, and the inclined surface is disposed on the trigger member 6a.

[0176] In this embodiment, the reset member 6b applies a reset force in the left and right directions to the protruding member 3, so that the protruding member 3 has a tendency to move toward the initial position; preferably, the reset member 6b is arranged between the protruding member 3 and the side wall of the accommodating cavity 107, and more preferably, the reset member 6b contacts the protruding member 3 in the left and right directions; the number of the reset member 6b is set to at least one, and when the reset member 6b is set to one, the reset member 6b can be set on either side of the left and right directions of the support portion 34, or the protruding member 3 is not connected to the two ends of the reset member 6b, but is connected to the area between the two ends of the reset member 6b; more preferably, there are two reset members 6b, which are respectively arranged on the left and right sides of the protruding member 3.

[0177] Installation process of the ink cartridge 100: When the ink cartridge 100 is in the initial state, the protruding member 3 is located at the initial position, the trigger member 6a is located at the protruding position, and the main body 35 does not cooperate with the color identification member 200; in the process of installing the ink cartridge 100 into the insertion space 350 in the forward direction, the trigger member 6a abuts against the action member and is triggered by the action member, and the trigger member 6a is moved from the protruding position to the trigger position by the backward triggering force, and the triggering force from front to back is converted into a force forcing the protruding member 3 to move in the left and right direction through the conversion mechanism 4; the protruding member 3 receives the triggering force, moves from the initial position to the matching position, and finally reaches the matching position, at which time the trigger member 6a enters the identification groove 201; in the above process, at least one of the reset members 6b undergoes elastic deformation and accumulates elastic force.

[0178] The removal process of the ink cartridge 100: when the ink cartridge 100 is in the installed state, the protruding member 3 is located in the mating position, and the main body 35 is located in the identification groove 201; in the process of taking the ink cartridge 100 out of the insertion space 350 in the backward direction, the trigger member 6a gradually disengages from the abutment with the action member, and the reset member 6b releases the stored elastic force, pushing the protruding member 3 to move from the mating position to the initial position; at the same time, through the conversion mechanism 4, the reset force in the left and right directions applied by the reset member 6b is converted into a force that forces the trigger member 6a to move from the back to the front; thus, the trigger member 6a moves from the trigger position to the protruding position, and finally reaches the protruding position, and the trigger mechanism 6 and the protruding member 3 are both reset.

[0179] In some embodiments, the moving distance of the protruding member 3 in the left and right directions can be controlled by adjusting parameters such as the extended length of the trigger member 6a, the inclination angle of the active member 4a and / or the driven member 4b, so as to ensure that the protruding member 3 can enter the identification slot 201, that is, the protruding member 3 in the ink cartridge for accommodating inks of different colors can produce different displacement amounts in the left and right directions in the above manner, thereby ensuring that the protruding members 3 of the ink cartridges of different colors can all enter the identification slot 201 in the corresponding color insertion space 350.

[0180] [Embodiment 8]

[0181] The trigger mechanism and conversion mechanism in this embodiment are different from those in the seventh embodiment.

[0182] like Fig.33 and Fig.34 As shown, unlike the above-mentioned embodiment, the trigger member 6a is configured to move in a straight line, specifically, the trigger member 6a moves in the front-to-back direction. In the present embodiment, the trigger member 6a is rotatably arranged on the box body 1, and the trigger member 6a can move in the left-right direction as well as in the up-down direction, and the trigger member 6a is also at least partially exposed to the box body 1 through the first through portion 100g; preferably, the trigger member 6a is configured as a fan-shaped block, the active member 4a is configured as a part of the fan-shaped block, and the driven member 4b also includes an inclined surface configured to be inclined relative to the left-right direction, and the fan-shaped block 6a cooperates with the inclined surface 4b; the setting position of the reset member 6b in the present embodiment is similar to that of the second embodiment, and will not be repeated here.

[0183] It should be understood that the trigger member 6a moves in the left-right direction, or in the up-down direction, or in the front-to-back direction, and the movement trajectory of the trigger member 6a is not necessarily parallel to the front-to-back direction, or parallel to the up-down direction, or parallel to the front-to-back direction. In other words, the movement direction of the trigger member 6a can also be inclined relative to any one of the left-right direction, the up-down direction, and the front-to-back direction, as long as the trigger member 6a has displacement in the left-right direction, the up-down direction, and the front-to-back direction.

[0184] Installation process of ink cartridge 100: When ink cartridge 100 is in the initial state, protruding member 3 is in the initial position, trigger member 6a is in the protruding position, and main body 35 does not cooperate with color identification member 200; in the process of installing ink cartridge 100 into insertion space 350 in the forward direction, trigger member 6a abuts against the action member and is triggered by the action member, and trigger member 6a is acted upon by the triggering force in the up-down direction and rotates around the rotation axis intersecting the up-down direction, and moves from the protruding position to the triggering position, and through conversion mechanism 4, the triggering force in the up-down direction is converted into a force forcing protruding member 3 to move in the left-right direction; protruding member 3 receives the triggering force, moves from the initial position to the cooperation position, and finally reaches the cooperation position, at which time trigger member 6a enters into identification groove 201; in the above process, reset member 6b undergoes elastic deformation and accumulates elastic force.

[0185] The removal process of the ink cartridge 100: when the ink cartridge 100 is in the installed state, the protruding member 3 is located in the mating position, and the main body 35 is located in the identification groove 201; in the process of removing the ink cartridge 100 from the insertion space 350 in the backward direction, the trigger member 6a gradually disengages from the abutment with the action member, and the reset member 6b releases the stored elastic force to push the protruding member 3; the protruding member 3 receives the reset force and moves from the mating position to the initial position, and through the conversion mechanism 4, the reset force is converted into a force that forces the trigger member 6a to reset in the up and down directions, thereby, the trigger member 6a moves from the trigger position to the protruding position, and finally reaches the protruding position, and the trigger mechanism 6 and the protruding member 3 are both reset.

[0186] In some embodiments, the size of the trigger member 6a protruding from the upper side wall 100e can be adjusted, or the rotation angle of the trigger member 6a can be controlled and adjusted, or the inclination angle of the inclined surface of the driven portion 4b can be adjusted to adjust the moving distance of the protruding member 3 in the left and right directions, that is, the protruding member 3 in the ink cartridge for accommodating different colors of ink can produce different displacement amounts in the left and right directions in the above manner, thereby ensuring that the protruding members 3 of the ink cartridges of different colors can all enter the identification slot 201 in the corresponding color insertion space 350.
