Description

Technical Field

[0001] This utility model relates to the field of printer consumables technology, and in particular to a printer imaging box. Background Technology

[0002] Inkjet printers on the market typically integrate a storage chip into the image cartridge. This chip stores image cartridge parameters (such as serial number, ink capacity, and usage status) and communicates with the printer via contacts. When the chip detects that the ink level is low, it sends a termination command to the printer to interrupt the printing job.

[0003] In existing technologies, such chips are generally fixed to the imaging cartridge body in a non-removable manner (e.g., by adhesive bonding or thermal soldering). When the chip needs a program upgrade, faulty component replacement, or adaptation to a new printer, the entire imaging cartridge must be sent to a service point for operation. This not only increases the user's operating costs and time, but also forcibly binds the lifespan of the chip to the consumable imaging cartridge, resulting in resource waste. Utility Model Content

[0004] The purpose of this invention is to propose a printer imaging box to remove the forced binding between the chip and the imaging box, so that the chip can be upgraded, replaced or adapted to new printers independently.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] Printer imaging cartridge, comprising:

[0007] An imaging box body, wherein a cavity is provided on the side of the imaging box body;

[0008] The chip assembly includes a chip and a bracket for mounting the chip. The inner wall of the cavity is provided with a first limiting structure, and the side of the bracket is provided with a second limiting structure that cooperates with the first limiting structure. The bracket is pushed into the cavity in a horizontal direction. While the first limiting structure and the second limiting structure cooperate to limit the movement, the bracket is snapped and fixed to the imaging box body.

[0009] As an optional solution for the printer imaging box, in the first limiting structure and the second limiting structure, one is a limiting groove and the other is a limiting rib that cooperates with the limiting groove.

[0010] As an optional solution for the printer imaging box, the first limiting structure is provided on both adjacent inner walls of the cavity, and the second limiting structure is provided on both adjacent sides of the bracket.

[0011] Both of the first limiting structures are either the limiting grooves or both are the limiting ribs;

[0012] Alternatively, one of the two first limiting structures may be the limiting groove, and the other may be the limiting rib.

[0013] As an optional embodiment of the printer imaging box, the limiting groove includes a straight groove, and the limiting rib includes a straight rib that mates with the straight groove;

[0014] Alternatively, the limiting groove may include an L-shaped groove, and the limiting rib may include an L-shaped rib that mates with the L-shaped groove.

[0015] As an optional embodiment of the printer imaging box, the limiting groove includes a strip groove, and the limiting rib includes a T-shaped rib; the bottom of the T-shaped rib is embedded in the strip groove, and the top abuts against the side wall of the cavity;

[0016] Alternatively, the limiting groove is a T-shaped groove, and the limiting rib includes a T-shaped rib adapted to the T-shaped groove.

[0017] As an alternative to the printer imaging cartridge, one end of the limiting groove located on one of the inner walls of the cavity extends through the side wall of the imaging cartridge body.

[0018] As an optional solution for the printer imaging box, the through end of the limiting groove is provided with a first guide surface;

[0019] And / or, the insertion end of the limiting rib is provided with a second guide surface.

[0020] As an optional embodiment of the printer imaging cartridge, the bracket is provided with an extension arm, and the extension arm is provided with a first snap-fit ​​structure; the side wall of the imaging cartridge body is provided with a second snap-fit ​​structure that snaps into the first snap-fit ​​structure.

[0021] As an optional solution for the printer imaging box, one of the first snap-fit ​​structure and the second snap-fit ​​structure is a slot and the other is a protrusion.

[0022] As an optional embodiment of the printer imaging cartridge, the side wall of the imaging cartridge body is provided with a groove communicating with the cavity, and the second snap-fit ​​structure is located in the groove. When the first snap-fit ​​structure and the second snap-fit ​​structure are snapped together, the outer surface of the extension arm is coplanar with the side wall of the imaging cartridge body.

[0023] As an alternative to the printer imaging cartridge, the depth of the cavity is greater than the height of the bracket along the height direction of the imaging cartridge body.

[0024] The beneficial effects of this utility model are:

[0025] This invention provides a printer imaging cartridge, comprising an imaging cartridge body and a chip assembly. The chip assembly includes a chip and a bracket. The chip is mounted on the bracket, which is pushed horizontally into a recessed cavity on the side of the imaging cartridge body.

When upgrading, replacing, or adapting to a new printer, the bracket can be pulled out in the opposite direction to the pushing direction to upgrade, replace, or adapt the chip to the new printer. This printer imaging cartridge removes the forced binding between the chip and the imaging cartridge body, allowing the chip to be upgraded, replaced, or adapted to a new printer independently, providing convenient operation and avoiding resource waste.

[0040] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0041] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] like Figures 1-10 As shown, this utility model provides a printer imaging cartridge, including an imaging cartridge body 1 and a chip 21. The imaging cartridge body 1 has a cavity 11 on its side. The chip assembly 2 includes the chip 21 and a bracket 22 for mounting the chip 21. The inner wall of the cavity 11 is provided with a first limiting structure, and the side of the bracket 22 is provided with a second limiting structure that cooperates with the first limiting structure. The bracket 22 is pushed into the cavity 11 in a horizontal direction. While the first limiting structure and the second limiting structure cooperate to limit the movement, the bracket 22 is also snapped and fixed to the imaging cartridge body 1.

[0043] It should be noted that the horizontal direction can be either a horizontal direction extending along the positive X-axis or a horizontal direction extending along the positive Y-axis. For example... Figure 2 As shown, in this embodiment, the horizontal direction is the horizontal direction extending along the positive Y-axis, that is, the direction opposite to the installation direction of the printer imaging box.

[0044] The bracket 22 and the imaging cartridge body 1 are aligned and positioned via a limiting structure, ensuring accurate snap-fit ​​fixing. This snap-fit ​​connection facilitates the assembly and disassembly of the bracket 22. When upgrading, replacing, or adapting the chip 21 to a new printer, simply pull the bracket 22 out in the opposite direction to the pushing direction to perform the upgrade, replacement, or adaptation. This printer imaging cartridge removes the forced binding between the chip 21 and the imaging cartridge body 1, allowing the chip 21 to be upgraded, replaced, or adapted to a new printer independently. This convenient operation avoids resource waste.

[0045] Specifically, in combination Figure 2 and Figure 4 As shown, a fixing groove 225 is provided on the bracket 22, and the chip 21 is placed in the fixing groove 225. The cavity 11 is provided at one corner of the imaging box body 1. The cavity 11 is set in the shape of "∟". This setting facilitates the processing of the cavity 11 on the one hand, and facilitates the assembly and disassembly of the chip assembly 2 on the other hand.

[0046] like Figure 1 , Figure 5 and Figure 8 As shown, along the height direction of the imaging box body 1 (i.e., the Z-axis direction perpendicular to the X and Y axes), the depth of the cavity 11 is greater than the height of the bracket 22. This arrangement ensures that the bracket 22 is fully embedded in the cavity 11, while still leaving a buffer space in the circumference. During the installation or removal of the printer imaging box, the internal guide rails and other structures of the printer have zero contact with the chip assembly 2, and will not interfere with the internal structure of the printer, resulting in better compatibility.

[0047] In one embodiment, in the first limiting structure and the second limiting structure, one is a limiting groove and the other is a limiting rib that cooperates with the limiting groove. The cooperation between the limiting groove and the limiting rib achieves the limiting cooperation between the side of the bracket 22 and the inner wall of the cavity 11, thereby limiting the other degrees of freedom of the bracket 22 on the imaging box body 1 except for the push-in and pull-out directions. This enables quick installation and positioning, and makes operation more convenient.

[0048] In one embodiment, the two adjacent inner walls of the cavity 11 are provided with a first limiting structure, and the two adjacent sides of the bracket 22 are provided with a second limiting structure. The two sets of vertically arranged limiting structures work together to apply constraints simultaneously in two orthogonal directions, namely the X-axis and the Y-axis, thereby achieving bidirectional positioning of the chip assembly 2 during installation, improving the positioning accuracy of the chip assembly 2, and making it easier to snap and fix the chip assembly 2.

[0049] Both first limiting structures are either limiting grooves or both are limiting ribs. Alternatively, one of the two first limiting structures is a limiting groove and the other is a limiting rib.

[0050] To ensure the stability of the chip assembly 2 on the imaging box body 1, after the side of the bracket 22 is limited and engaged with the inner wall of the cavity 11, a snap-fit ​​structure is provided on the bracket 22 to snap and fix the two together with the imaging box body 1.

[0051] Specifically, the bracket 22 is provided with an extension arm 224, and the extension arm 224 is provided with a first snap-fit ​​structure; the side wall of the imaging box body 1 is provided with a second snap-fit ​​structure that snaps into the first snap-fit ​​structure. The extension arm 224 is located at the end of the bracket 22 when it is pushed in horizontally. The two adjacent inner walls of the cavity 11 are provided with a first limiting structure, and the two adjacent sides of the bracket 22 are provided with a second limiting structure. When the bracket 22 is pushed into the cavity 11, the second limiting structure on one side of the bracket 22 first engages with the first limiting structure on one inner side wall of the cavity 11 to guide the pushing of the bracket 22 until the bracket 22 is pushed into the limit position. At the same time, the second limiting structure on the other side of the bracket 22 engages with the first limiting structure on the other inner side wall of the cavity 11, and the extension arm 224 is elastically deformed by the pressure of the side wall of the imaging box body 1, so that the first snap-fit ​​structure and the second snap-fit ​​structure snap into each other and are fixed.

[0052] The locking structure can only engage when the limiting fit is in place, avoiding stress concentration caused by local locking; at the same time, the collision of the first and second locking structures at the moment of locking produces a crisp sound, which serves as a perceptible signal that the fit is in place.

[0053] Specifically, of the first and second snap-fit ​​structures, one is a slot 32 and the other is a protrusion 31. Along the pushing and pulling direction of the bracket 22, the opposite side walls of the protrusion 31 are both set as third guide surfaces 311. The third guide surfaces 311 guide the sliding in and out of the slot 32, so that when the bracket 22 is snapped into or unsnapped from the imaging box body 1, the extension arm 224 is prevented from breaking due to hard deformation, thus extending the service life of the bracket 22.

[0054] Specifically, the cross-section of the convex 31 is set to an isosceles trapezoid shape.

[0055] The imaging cartridge body 1 has a groove 12 on its side wall that communicates with the cavity 11. The second snap-fit ​​structure is located in the groove 12. When the first snap-fit ​​structure and the second snap-fit ​​structure are engaged, the outer surface of the extension arm 224 is coplanar with the side wall of the imaging cartridge body 1. Setting the outer surface of the extension arm 224 to be coplanar with the side wall of the imaging cartridge body 1 further avoids interference between the bracket 22 and the internal structure of the printer. This setting does not require any changes to the structure of the imaging cartridge mounting position on the printer, making it more widely applicable.

[0056] There are various ways to set the specific structure of the limiting groove and the limiting rib, as well as the setting position of the slot 32 and the protrusion 31. This utility model provides three specific embodiments for explanation.

[0057] Example 1:

[0058] like Figures 1-4 As shown, in the printer imaging box provided in this embodiment, the two adjacent inner walls of the cavity 11 on the imaging box body 1 are the first inner wall and the second inner wall, respectively. The first inner wall is parallel to the pushing-in and pulling-out direction of the bracket 22, and the second inner wall is perpendicular to the pushing-in and pulling-out direction of the bracket 22.

[0059] Specifically, a first limiting groove is provided on the first inner wall, and a second limiting groove is provided on the second inner wall. A first limiting rib is provided on one side of the bracket 22, and a second limiting rib is provided on the other side.

[0060] Specifically, one end of a limiting groove located on one of the inner sidewalls of the cavity 11 is provided to facilitate the positioning and pushing of the bracket 22 into the cavity 11 from one side and the limiting groove, so as to ensure that the first snap-fit ​​structure and the second snap-fit ​​structure are accurately snapped together.

[0061] In one embodiment, the limiting groove includes a T-shaped groove 112, and the limiting rib includes a T-shaped rib 222 adapted to the T-shaped groove 112. The cooperation between the T-shaped groove 112 and the T-shaped rib 222 can restrict the four degrees of freedom of the support 22 (up, down, left, and right) and increase the contact area between the support 22 and the imaging box body 1.

[0062] In this embodiment, the first limiting groove is configured as a T-shaped groove 112, with one end of the T-shaped groove 112 being through-hole, the top of the T-shaped groove 112 located inside the imaging box body 1, and the bottom being through-hole through the first inner wall. That is, the opening direction of the bottom of the T-shaped groove 112 is perpendicular to the pushing direction of the bracket 22, and the groove extends into the imaging box body 1. The T-shaped rib 222 extends outward from one side of the bracket 22. After the T-shaped rib 222 engages with the T-shaped groove 112, the T-shaped rib 222 is embedded into the imaging box body 1, and one side of the bracket 22 abuts against the first inner wall.

[0063] In one embodiment, the through end of the limiting groove is provided with a first guide surface 1121; and / or, the insertion end of the limiting rib is provided with a second guide surface 2221. The provision of the first guide surface 1121 and the second guide surface 2221 makes it easier for the limiting rib to be inserted into the limiting groove when the bracket 22 is positioned and docked with the imaging box body 1, thus reducing the difficulty of the docking and positioning operation.

[0064] In this embodiment, two first guide surfaces 1121 are arranged opposite each other at the through end of the bottom of the T-slot 112, and two second guide surfaces 2221 are arranged opposite each other at the top end of the T-rib 222. The two first guide surfaces 1121 are used to guide the bottom of the T-rib 222 into the bottom of the T-slot 112, and the two second guide surfaces 2221 are used to guide the top of the T-rib 222 into the top of the T-slot 112. This arrangement not only increases the convenience of pushing the bracket 22 in, but also facilitates the processing of the T-slot 112 and the T-rib 222.

[0065] Furthermore, the T-slot 112 extends a certain distance towards the second inner wall to increase the guiding distance and support area of ​​the bracket 22, thereby ensuring the stability of the bracket 22 installation.

[0066] In other embodiments, the limiting groove includes a strip groove, and the limiting rib includes a T-shaped rib 222; the bottom of the T-shaped rib 222 is embedded in the strip groove, and the top abuts against the side wall of the cavity 11. That is, the first limiting groove is set as a strip groove with one end penetrating through the side wall of the imaging box body 1 and the other end penetrating through the first inner wall, and the bottom of the T-shaped rib 222 is inserted into the strip groove accordingly, and after being inserted to the bottom, the top abuts against the side wall of the imaging box body 1.

[0067] In one embodiment, the limiting groove includes an L-shaped groove 113, and the limiting rib includes an L-shaped rib 223 that cooperates with the L-shaped groove 113. The L-shaped groove 113 and the L-shaped rib 223 cooperate to simultaneously restrict the four degrees of freedom of the bracket 22 in the up, down, left, and right directions, and increase the contact area between the bracket 22 and the imaging box body 1.

[0068] In this embodiment, the second limiting groove is an L-shaped groove 113, and the second limiting rib is an L-shaped rib 223, with the L-shaped groove 113 and the L-shaped rib 223 working together.

[0069] In this embodiment, the T-shaped rib 222 on one side of the bracket 22 cooperates with the T-shaped groove 112 of the first inner wall for limiting the position, and the L-shaped rib 223 on the other side of the bracket 22 cooperates with the L-shaped groove 113 of the second inner wall for limiting the position, forming an asymmetrical layout to achieve the function of preventing incorrect installation.

[0070] In this embodiment, the protrusion 31 is located on the inner side of the extension arm 224, and the groove 32 is located in the recess 12. When the bracket 22 is pushed into the cavity 11, the T-shaped rib 222 is first aligned with the T-shaped groove 112, and then a pushing force is applied to the bracket 22 in the horizontal direction. After the T-shaped rib 222 is fully inserted into the T-shaped groove 112, the L-shaped rib 223 is pushed into the L-shaped groove 113, and the protrusion 31 slides into the groove 32.

[0071] Example 2:

[0072] like Figures 5-7 As shown, the printer imaging box provided in this embodiment differs from the printer imaging box provided in Embodiment 1 in that: a limiting rib is provided on the second inner wall, and a limiting groove is provided on the other side of the bracket 22. Other structures are the same as those of the printer imaging box provided in Embodiment 1, and will not be described again here.

[0073] Specifically, the limiting groove includes a straight groove 221, and the limiting rib includes a straight rib 111 that cooperates with the straight groove 221. That is, a straight rib 111 is provided on the second inner wall, and a straight groove 221 is provided on the other side of the bracket 22. When the bracket 22 is pushed into the cavity 11, the T-shaped rib 222 is first aligned with the T-shaped groove 112, and then a pushing force is applied to the bracket 22 in the horizontal direction. After the T-shaped rib 222 is fully inserted into the T-shaped groove 112, the straight groove 221 and the straight rib 111 cooperate to limit the movement.

[0074] Furthermore, in order to ensure that the straight rib 111 can smoothly enter the straight groove 221, the top of the straight rib 111 is designed to gradually expand from the top to the bottom, so that the area of ​​the top of the straight rib 111 is small, making it easier to enter the straight groove 221.

[0075] Example 3:

[0076] like Figures 8-10 As shown, the printer imaging box provided in this embodiment differs from the printer imaging box provided in Embodiment 1 in that: the extension arm 224 is provided with a slot 32 that penetrates the inner and outer walls, and a protrusion 31 is provided in the groove 12. Other structures are the same as those of the printer imaging box provided in Embodiment 1, and will not be described further here.

[0077] Specifically, the latching protrusion 31 is provided with a third guide surface 311 on both sides along the push-in and pull-out direction, and one end of the latching groove 32 is provided through the lower end of the extension arm 224, so that when the push force is applied to the bracket 22, the end of the extension arm 224 first abuts against the third guide surface 311 on the side of the latching protrusion 31 near the cavity 11, and then under the guidance of the third guide surface 311, the bracket 22 continues to push forward until the latching protrusion 31 slides into the latching groove 32.

[0078] When the bracket 22 is pushed into the cavity 11, the T-shaped rib 222 is first aligned with the T-shaped groove 112, and then a horizontal pushing force is applied to the bracket 22. After the T-shaped rib 222 is fully inserted into the T-shaped groove 112, the L-shaped rib 223 is pushed into the L-shaped groove 113, and the locking protrusion 31 slides into the locking groove 32 under the guidance of the third guide surface 311. Similarly, when the bracket 22 is pulled out of the cavity 11, the third guide surface 311 on the other side of the locking protrusion 31 guides the extension arm 224, causing the locking groove 32 on the extension arm 224 to gradually disengage from the locking protrusion 31.

[0079] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
