Specifically, the side of chip mounting bracket 52 is equipped with spacing hole 53, and the side of casing 1 corresponds and is equipped with spacing post 13, and the correspondence is equipped with spacing post 13 on the left surface of casing 1 and/or the right surface promptly, and spacing hole 53 passes through the buckle with spacing post 13 and is connected to set up chip mounting bracket 52 detachably in the top surface of casing 1. The chip mounting bracket 52 may also adopt any other way capable of being detachably connected to the housing 1, for example, the side of the chip mounting bracket 52 is provided with a limit hole 53, the side of the housing 1 is correspondingly provided with a threaded hole, and a bolt passes through the limit hole 53 and is locked in the threaded hole, so that the chip mounting bracket 52 is detachably disposed on the top surface of the housing 1.

It is understood that the chip mounting bracket 52 may also be fixedly disposed on the top surface of the housing 1, for example, the chip mounting bracket 52 is fixedly disposed on the top surface of the housing 1 by welding or the chip mounting bracket 52 is integrally formed with the housing 1.

Further, the chip 51 may be fixedly disposed in the consumable chip mounting portion, for example, the chip 51 may be fixedly disposed in the consumable chip mounting portion by soldering; the chip 51 may also be detachably disposed in the consumable chip mounting portion, for example, the consumable chip mounting portion is a slot-type structure, and the chip 51 is detachably disposed in the slot-type structure.

Further, the chip 51 may be horizontally disposed on the chip consumable mounting portion, that is, the surface of the chip 51 where the electrical interface is located is perpendicular to the Z axis; the chip 51 may be disposed on the consumable mounting portion in an inclined state according to the actual position of the contact pins in the consumable mounting portion, i.e., the surface of the chip 51 where the electrical interface is located intersects with the Z-axis but is not perpendicular thereto.

The right surface of the housing 1 is also provided with a face cover 11, wherein the housing 1 and the face cover 11 may be both made of plastic or metal. The surface cover 11 may be fixedly disposed on the housing 1 by welding or the surface cover 11 and the housing 1 are integrally formed, and the surface cover 11 may also be detachably disposed on the housing 1 by screw-fitting or other methods to close the housing 1 and enable the interior of the housing 1 to form an ink storage chamber 12 for storing ink.

An ink outlet 6 is provided on the front surface of the housing 1 and is engageable with an ink supply needle provided on a print head in a printing apparatus to supply ink stored in the ink reservoir 12 to the print head.

Referring to fig. 3 and 4, an air inlet 14 is formed on the housing 1 to communicate the interior of the ink storage chamber 12 with the external atmosphere, so that when the ink in the ink storage chamber 12 is consumed, the external atmosphere can be timely supplemented to the interior of the ink storage chamber 12 and the pressure inside the ink storage chamber 12 can be timely adjusted. The air inlet 14 may be formed on at least one of a front surface, a rear surface, a left surface, a right surface, a top surface, or a bottom surface of the case 1.

Referring to fig. 5 to 9, an accommodating cavity 15 is formed in the housing 1, the light shielding member 4 is detachably mounted in the accommodating cavity 15, and at least a portion of the light shielding member 4 extends out of the accommodating cavity 15 and the top surface of the housing 1. In the process of use or transportation, when the light shielding member 4 is damaged due to collision or improper use, the user can replace the light shielding member 4 on the housing 1, and the ink cartridge 100 is prevented from being out of order due to the damage of the light shielding member 4.

Further, the top surface of the housing 1 is provided with a receiving groove 16, the receiving groove 16 communicates with the receiving cavity 15, and a front end of the receiving groove 16 is provided with an opening (not shown in the figure) in the mounting direction D.

The light shielding member 4 includes a shielding portion 42 and a supporting portion 41 connected; the supporting portion 41 is received in the receiving cavity 15, and the shielding portion 42 protrudes from the top surface of the housing 1 from the receiving groove 16.

Specifically, when the light shielding member 4 moves in the direction opposite to the mounting direction D, the shielding portion 42 can pass through the opening and be accommodated in the accommodating groove 16. In addition, the width of the receiving groove 16 along the Y axis should be larger than the thickness of the shielding portion 42 along the Y axis, and the supporting portion 41 can abut against the bottom wall or the side wall of the receiving cavity 15, thereby supporting the shielding portion 42 and allowing the shielding portion 42 to protrude from the receiving groove 16 from the top surface of the housing 1.

Further, the front end of the accommodating chamber 15 in the positive direction of the X axis is an unclosed structure, so that the support portion 41 can move into the accommodating chamber 15 in the negative direction of the X axis.

Specifically, the width of the supporting portion 41 along the Y axis is larger than the width of the receiving groove 16 along the Y axis to prevent the supporting portion 41 from falling off from the receiving groove 16 after moving in the positive direction of the Z axis.

Further, the shielding portion 42 is a plate-shaped structure, and the shielding portion 42 may be made of metal, opaque plastic or other opaque materials. The support portion 41 includes an elastic member, which can be abutted against the bottom wall and/or the side wall of the accommodating cavity 15.

Since the size of the shield portion 42 is generally small, its force-bearing area is reduced, so that the top surface of the shield portion 42 becomes sharp and easily cuts the user's finger. When the supporting portion 41 is an elastic member, after the top surface of the shielding portion 42 is stressed, the elastic member can be compressed along the opposite direction of the Z axis, so as to drive the shielding portion 42 to move along the opposite direction of the Z axis, thereby realizing automatic avoidance of the shielding portion 42 after being stressed, and preventing the shielding portion 42 from being damaged due to extrusion or collision during installation, disassembly or transportation of the light shielding member 4.

Furthermore, the elastic element is a spring plate, and the supporting portion 41 includes at least two spring plates, and the spring plates are connected to the shielding portion 42 at intervals; the elastic sheets are in a bending structure, and the bending directions of every two adjacent elastic sheets are different or opposite.

Specifically, the elastic sheet may be bent into a claw shape, a C shape, a U shape, a wave shape, and other structures that enable the elastic sheet to have elasticity, which is not limited herein. In this embodiment, the shielding portion 42 includes a first elastic sheet 411 and a second elastic sheet 412, the first elastic sheet 411 and/or the second elastic sheet 412 may be bent into a claw-shaped structure by metal or other elastic materials, and the bending direction of the first elastic sheet 411 is opposite to the bending direction of the second elastic sheet 412. The bottom of the first resilient piece 411 and/or the second resilient piece 412 may directly abut against the bottom of the accommodating cavity 15, or the curved portion of the first resilient piece 411 and/or the second resilient piece 412 may abut against the sidewall of the accommodating cavity 15.

It is understood that the elastic member may also be a spring, a plate spring or other elastic member, so that when the top surface of the shielding portion 42 is stressed, the shielding portion 42 is driven to move along the direction opposite to the Z-axis by the elastic member, and automatic avoidance is achieved.

Referring to fig. 4 and 9, a stopping portion 17 is disposed at the bottom of the accommodating cavity 15, and the stopping portion 17 extends from the bottom wall of the accommodating cavity 15 to a direction close to the accommodating groove 16 to limit the position of the supporting portion 41 in the accommodating cavity 15.

Specifically, the stopping portion 17 is a limiting rib extending from the bottom wall of the accommodating cavity 15 to a direction close to the accommodating groove 16, and the stopping portion 17 may be formed at the front side of the supporting portion 41 along the positive direction of the X axis to limit the supporting portion 41 from falling off from the front end of the accommodating cavity 15 after moving along the positive direction of the X axis; the stopping portions 17 may also be formed on the front and rear sides of the supporting portion 41 along the X axis to limit the moving distance of the supporting portion 41 along the X axis in both forward and reverse directions, and also to limit the installation position of the supporting portion 41 in the accommodating cavity 15.

Referring to fig. 10 to 12, a gap portion is formed between any two adjacent electrical interfaces on the chip 51, the gap portion includes a first boundary line L1 and a second boundary line L2, and the second boundary line L2 is closer to the positive direction of the Y axis than the first boundary line L1. For example, the first electrical interface 511 is adjacent to the second electrical interface 512, and a gap portion is formed between the first electrical interface 511 and the second electrical interface 512, and includes a first boundary line L1 close to the first electrical interface 511 and a second boundary line L2 close to the second electrical interface 512.

After the shielding portion 42 extends out of the top surface of the housing 1 from the receiving groove 16, two projection lines formed by two side surfaces of the shielding portion 42 parallel to the mounting direction D in vertical projection are not overlapped and/or intersected with the first boundary line L1 and the second boundary line L2, and the two projection lines are located between extension lines of the first boundary line L1 and the second boundary line L2, so as to reduce the size of the light shielding member 4 and meet the design requirements of miniaturization and compactness of the printing apparatus.

In the present embodiment, the gap portion formed between the first electrical interface 511 and the second electrical interface 512 includes a first boundary line L1 and a second boundary line L2. Two projection lines formed by projecting the two side surfaces of the shielding portion 42 parallel to the mounting direction D perpendicularly (in the direction opposite to the Z axis) are parallel to the first boundary line L1 and the second boundary line L2. Both projection lines are located between the extension lines of the first boundary line L1 and the second boundary line L2 in the opposite direction of the mounting direction D.

Further, the distance between the two side surfaces of the shielding portion 42 parallel to the mounting direction D is smaller than the distance between the first boundary line L1 and the second boundary line L2 of any one of the gap portions, that is, the thickness of the shielding portion 42 along the Y axis is smaller than the distance between any two adjacent electrical interfaces. The distance between two side surfaces of the shielding portion 42 parallel to the mounting direction D may be 0.1mm to 0.5mm, and specifically may be 0.1mm, 0.2mm, 0.3mm, 0.4mm, and 0.5mm, which is not limited herein. In the present embodiment, since the distance between the first boundary line L1 and the second boundary line L2 of the gap portion formed between the adjacent first electrical interface 511 and the second electrical interface 512 is 0.3mm, the distance between the two side surfaces of the shielding portion 42 parallel to the mounting direction D may be designed to be 0.2 mm.

Referring to fig. 13, in a possible embodiment provided by the application, when the chip component 5 is disposed on the housing 1 at the front side of the accommodating cavity 15 along the positive direction of the X axis and the chip component 5 interferes with the light shielding member 4 and is accommodated in the accommodating cavity 15, an avoiding groove (not shown in the figure) is disposed on the top surface of the housing 1, the avoiding groove is disposed at the front side of the accommodating cavity 15 along the positive direction of the X axis and is communicated with the accommodating cavity 15, and the length of the avoiding groove along the X axis and the width of the avoiding groove along the Y axis are respectively greater than the length of the supporting portion 41 of the light shielding member 4 along the X axis and the width of the supporting portion along the Y axis. The user moves the light shielding member 4 along the first mounting direction S1 to accommodate the supporting portion 41 in the avoiding groove, and then moves the light shielding member 4 along the second mounting direction S2, the supporting portion 41 moves directly into the accommodating cavity 15, and the shielding portion 42 passes through the opening formed at the front end of the accommodating cavity 16 and is accommodated in the accommodating cavity 16, so as to solve the problem that the user cannot install the light shielding member 4 in the accommodating cavity 15 and the accommodating cavity 16 due to interference of the chip component 5 or needs to remove the chip component 5 from the top surface of the housing 1 in advance, which reduces the installation efficiency.

Specifically, the first mounting direction S1 is parallel to the Z axis, and the first mounting direction S1 is in the same direction as the opposite direction of the Z axis; the second mounting direction S2 is parallel to the X-axis, and the second mounting direction S2 is in the same direction as the opposite direction of the X-axis.

When the light shutter 4 needs to be replaced, the light shutter 4 is first moved a certain distance in the direction opposite to the first mounting direction S1 so that the supporting portion 41 is out of the limit of the stopping portion 17, then moved in the direction opposite to the second mounting direction S2 until the shielding portion 42 completely falls off from the opening opened at the front end of the receiving groove 16, and finally moved continuously in the direction opposite to the first mounting direction S1 so that the light shutter 4 is removed from the top surface of the housing 1.

In another possible embodiment provided by the present application, when the chip component 5 is reduced in size, changed in structure or changed in mounting position on the housing 1, and the chip component 5 is not interfered with the light shielding member 4 being received in the receiving cavity 15, the user can move the light shielding member 4 directly along the second mounting direction S2 to directly place the supporting portion 41 in the receiving cavity 15, and the shielding portion 42 is received in the receiving cavity 16 through the opening opened at the front end of the receiving cavity 16.

When the light shielding member 4 needs to be replaced, the light shielding member 4 is moved along the first mounting direction S1 for a certain distance to separate the supporting portion 41 from the limit of the stopping portion 17, and then moved along the second mounting direction S2 until the shielding portion 42 completely falls off from the opening opened at the front end of the receiving slot 16, so that the light shielding member 4 can be removed from the top surface of the housing 1.

When assembling, the chip 51 is first fixedly or detachably mounted on the chip consumable mounting part of the chip mounting bracket 52, and then the chip mounting bracket 52 is fixedly or detachably mounted on the top surface of the housing 1, then, the light shielding member 4 is moved along the first mounting direction S1, so that the supporting portion 41 is received in the avoiding groove, and continues to move along the second mounting direction S2, so that the shielding portion 42 is received in the receiving groove 16 after passing through the opening formed at the front end of the receiving groove 16, the supporting portion 41 is received in the receiving cavity 15, the supporting portion 41 can be abutted against the bottom wall and/or the side wall of the receiving cavity 15, thereby supporting the shielding portion 42 and allowing the shielding portion 42 to protrude from the receiving groove 16 to the top surface of the housing 1, and finally the user holds the handle 2 with one hand and the housing 1 with the other hand to mount the ink cartridge 100 in the mounting direction D in the consumable mounting part of the printing apparatus. The user may also hold the handle 12 with one hand and pull the ink cartridge 100 out of the consumable supply mounting portion of the printing apparatus in the opposite direction to the mounting direction D.

Compared with the prior art, the ink cartridge 100 provided by the application realizes that the light shielding piece 4 is detachably arranged in the housing 1 by detachably installing the light shielding piece 4 in the housing cavity 15 and enabling the light shielding piece 4 to extend out of the top surface of the housing 1 from the housing cavity 15, and solves the problem that the replacement cannot be carried out in the existing ink cartridge because the light shielding piece 4 is fixedly arranged on the housing 1. In addition, because the light shielding member 4 can be replaced on the housing 1, the light shielding member 4 can be designed to have different sizes so as to meet the use requirements of printing devices with different space sizes, and recycling of the ink cartridge and miniaturization and compactness design of the printing device are facilitated.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
