Description

Technical Field

[0001] This utility model relates to the field of image forming technology, and in particular to an ink cartridge refilling tool. Background Technology

[0002] There is a type of high-capacity ink cartridge that has an outlet section with a valve structure and is relatively expensive. In order to reduce the cost of use, users have the need to add ink themselves to achieve cartridge reuse. Related manufacturers have also launched product solutions that can be refilled from the outlet section. However, the fit between the filling container and the ink cartridge in this type of solution is not very stable. During the ink refilling process, users need to manually straighten the filling container and the ink cartridge, otherwise ink leakage is likely to occur due to misalignment. Utility Model Content

[0003] To solve at least one of the aforementioned technical problems, this utility model provides an ink cartridge refilling tool. The ink cartridge has an open engagement cavity and an ink cavity, and the ink cartridge also has a movable valve core for changing the communication state between the ink cavity and the engagement cavity. A locking protrusion is provided on the outer side of the ink cartridge.

[0004] The ink cartridge refilling tool includes an ink filling container and an adapter that is detachably connected to the ink cartridge. The adapter includes a base plate and a flow path portion disposed through the base plate along a first direction. The flow path portion is used to conduct the ink filling container and the ink cartridge. The adapter also includes a locking portion that engages with a locking protrusion.

[0005] The ink container has an ink storage chamber for storing ink and an ink outlet for discharging ink. The flow path includes a first tube and a second tube that are interconnected. The first tube and the second tube are located on opposite sides of a substrate in a first direction. A barrier portion is provided on the outside of the first tube that abuts against the ink outlet in the first direction.

[0006] The enclosure portion is at least partially larger in size in the first direction than the first pipe in the first direction. The first pipe is inserted into the outlet portion and communicates with the ink storage chamber. The second pipe is inserted into the connecting chamber and abuts against the movable valve core and communicates with the ink chamber.

[0007] This invention provides a baffle on the adapter to guide the connection between the first tube and the outlet, suppressing the tilt of the ink container relative to the first direction, improving the connection stability between the adapter and the ink container, making the ink filling process easier to operate and less prone to ink leakage.

[0008] In some embodiments, the enclosure includes an outer retaining ring coaxially disposed with the first pipe, and the outlet is a stepped columnar structure, the outlet including a first stepped surface abutting the outer retaining ring in a first direction, the dimension of the outer retaining ring in the first direction being larger than the dimension of the first pipe in the first direction.

[0009] In some embodiments, the enclosure portion further includes an inner retaining ring located between the outer retaining ring and the first pipe, wherein the outlet portion overlaps with the inner retaining ring in the first direction.

[0010] In some embodiments, the outlet and the inner retaining ring are configured such that when the outlet is inserted into the inner retaining ring, the end of the outlet in the first direction has a gap between it and the substrate, and the gap is defined between the first tube and the inner retaining ring to form an overflow prevention zone.

[0011] In some embodiments, the enclosure portion further includes a guide rib disposed inside the outer retaining ring, and the outlet portion further includes a second stepped surface that abuts against the guide rib in a first direction, wherein the guide rib overlaps with the first pipe in the first direction.

[0012] In some embodiments, the guide rib extends in a first direction and is connected to the inner retaining ring.

[0013] In some embodiments, a guide rib is disposed between the outer retaining ring and the inner retaining ring, and in a first direction, the lengths of the outer retaining ring, the guide rib, and the inner retaining ring decrease sequentially.

[0014] In some embodiments, the locking protrusions are located on two sidewalls of the ink cartridge that are disposed opposite each other in the second direction, the substrate is provided with extension portions at both ends in the second direction, the engaging portion is located at the end of the extension portion in the second direction, and the second direction intersects with the first direction.

[0015] In some embodiments, the engaging portion includes engaging arms and operating arms that are movable in a second direction. There are two engaging arms and two operating arms. The engaging arms are located on the side of the extension portion facing the ink cartridge. The two engaging arms are provided with protrusions that cooperate with the locking protrusions on opposite sides in the second direction. The operating arms are located on the side of the extension portion facing the ink filling container.

[0016] In some embodiments, the enclosure includes an outer retaining ring coaxially disposed with the first pipe fitting, and the adapter also includes limiting retaining rings disposed on opposite sides of the outer retaining ring in a second direction, with each operating arm located within a limiting retaining ring.

[0017] In some embodiments, the limiting ring has an outer pressure plate on the side of the ink cartridge that is parallel to or coincides with the plane of the substrate on the first direction.

[0018] In some embodiments, a support member is also included for securing the ink cartridge when refilling it. The support member has a flat support surface and at least one receiving groove for accommodating a portion of the ink cartridge.

[0019] In some embodiments, the support is a fixed structure, or the support is a foldable plate-like structure. Attached Figure Description

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0045] This utility model provides an ink cartridge refilling tool for refilling ink cartridge 1.

[0046] See Figure 1-2 The ink cartridge 1 in this embodiment has the following structure: taking the height direction of the ink cartridge 1 as a first direction, which is parallel to the plumb line direction, the ink cartridge 1 has a top wall 111 and a bottom wall 112 facing each other in the first direction; taking the width direction of the ink cartridge 1 as a second direction, the ink cartridge 1 has two side walls 113 facing each other in the second direction; taking the length direction of the ink cartridge 1 as a third direction, the ink cartridge 1 has a front wall 114 and a rear wall 115 facing each other in the third direction; the ink cartridge 1 can be extended along the third direction (specifically... Figure 1 The middle three-way arrow points to the right) horizontally inserts into the box mounting part of the printing device.

[0047] See Figure 1-7 The ink cartridge 1 includes an ink reservoir 125 and an adapter 126. An ink cavity 122 is provided within the ink reservoir 125. A chip 127 and a gas-liquid exchange section 120 are provided on the adapter 126. The gas-liquid exchange section 120 is used for fluid exchange with the outside environment. In this embodiment, the top wall 111 of the ink cartridge 1 is formed on the ink reservoir 125, and the bottom wall 112 is formed on the adapter 126. The front wall 114, rear wall 115, and side wall 113 of the ink cartridge each include portions formed on the ink reservoir 125 and portions formed on the adapter 126. The liquid exchange section 120 is disposed on the bottom wall 112. In the third direction, the distance from the liquid exchange section 120 to the rear wall 115 is less than the distance to the front wall 114. The ink cartridge 1 has a recess 116 at the intersection of the top wall 111 and the rear wall 115. The recess 116 has intersecting first walls 117 and second walls 118. The first wall 117 is connected to the top wall 111, and the second wall 118 is connected to the rear wall 115. The two opposing side walls 113 of the ink cartridge 1 in the second direction have locking protrusions 119 on the adapter 126.

[0048] The gas-liquid exchange section 120 of the ink cartridge 1 extends inward to the connecting cavity 121 and the ink cavity 122. The gas-liquid exchange section 120 is an opening formed on the bottom wall 112 of the connecting cavity 121 facing the outside. The ink cavity 122 is used to store ink. The ink cartridge 1 also has a movable valve core 123 for changing the communication state between the ink cavity 122 and the connecting cavity 121. An elastic member 124 is provided between the movable valve core 123 and the ink cavity 122. With the bottom wall 112 of the ink cartridge 1 facing upward, when the movable valve core 123 is subjected to an external force and moves downward, the elastic member 124 is compressed, and the connecting cavity 121 and the ink cavity 122 are connected, allowing the ink cavity 122 to exchange gas and liquid with the outside. When the external force on the movable valve core 123 disappears, it returns to its original position under the action of the elastic member 124, and the connecting cavity 121 and the ink cavity 122 are no longer connected, preventing the ink cavity 122 from exchanging gas and liquid with the outside.

[0049] See Figure 1 The ink cartridge refill tool includes an ink container 2 and an adapter 3 that is detachably connected to the ink cartridge 1. The ink container 2 has an ink storage chamber 21 for storing ink and an ink outlet 22 for discharging ink.

[0050] See Figure 3-7The adapter 3 includes a base plate 31 and a flow path 32 extending through the base plate 31 along a first direction. The axial direction of the flow path 32 is the first direction. The flow path 32 is used to connect the ink container 2 and the ink cartridge 1. The flow path 32 includes a first tube 321 and a second tube 322 that are interconnected. The first tube 321 and the second tube 322 are located on opposite sides of the base plate 31 in the first direction. The base plate 31 has a blocking portion 33 on the outside of the first tube 321 that abuts against the outlet portion 22 in the first direction. At least a portion of the blocking portion 33 is larger in the first direction than the first tube 321 in the first direction. The first tube 321 passes through the outlet portion 22 and communicates with the ink storage chamber 21. The second tube 322 passes through the connecting cavity 121 and abuts against the movable valve core 123 and communicates with the ink chamber 122. A sealing ring 24 can also be provided in the joint cavity 121 for interference fit with the outer wall of the second tube 322 to prevent ink leakage.

[0051] Specifically, the enclosure portion 33 includes an outer retaining ring 331 coaxially disposed with the first pipe fitting 321, and the outlet portion 22 is a stepped columnar structure. The outlet portion 22 includes a first stepped surface 221 abutting against the outer retaining ring 331 in a first direction. The outer retaining ring 331 is larger in the first direction than the first pipe fitting 321 in the first direction. The enclosure portion 33 also includes an inner retaining ring 332 located between the outer retaining ring 331 and the first pipe fitting 321. In the first direction, the outlet portion 22 overlaps with the inner retaining ring 332. The enclosure portion 33 also includes a guide rib 333 disposed inside the outer retaining ring 331, and the outlet portion 22 also includes a second stepped surface 222 abutting against the guide rib 333 in the first direction. In the first direction, the guide rib 333 overlaps with the first pipe fitting 321. Specifically, the guide rib 333 extends along the first direction and is connected to the inner retaining ring 332. The guide rib 333 is disposed between the outer retaining ring 331 and the inner retaining ring 332. In the first direction, the lengths of the outer retaining ring 331, the guide rib 333 and the inner retaining ring 332 decrease sequentially.

[0052] See Figure 7 In this embodiment, the outlet portion 22 and the inner retaining ring 332 are configured such that when the outlet portion 22 is inserted into the inner retaining ring 332, the outlet portion 22 has a gap portion between its end in the first direction and the substrate 31, and the gap portion is limited between the first tube 321 and the inner retaining ring 332 to form an overflow prevention zone 34.

[0053] See Figure 3-7In this embodiment, the substrate 31 has extension portions 35 at both ends in the second direction, and the adapter 3 further includes a locking portion that engages with the locking protrusion 119. The locking portion is located at the end of the extension portion 35 in the second direction. Specifically, the locking portion includes a locking arm 361 and an operating arm 362 that are movable in the second direction. There are two locking arms 361 and two operating arms 362. The locking arm 361 is located on the side of the extension portion 35 facing the ink cartridge 1 (i.e., the downward side). The two locking arms 361 have protrusions 3611 that engage with the locking protrusion 119 on opposite sides in the second direction. The operating arm 362 is located on the side of the extension portion 35 facing the ink container 2 (i.e., the upward side). The adapter 3 also includes limiting rings 37 located on opposite sides of the outer retaining ring 331 in the second direction. Each operating arm 362 is located within a limiting ring 37. The limiting rings 37 are used to protect the operating arm 362 and limit its range of motion. The limiting ring 37 has an outer pressure plate 38 on the side of the ink cartridge 1 (i.e. the downward side) that is parallel to or coincides with the plane of the substrate 31. The outer pressure plate 38 is used to provide an auxiliary force point for the user when the adapter 3 is installed to the ink cartridge 1.

[0054] See Figure 6-7 During the docking process between the ink container 2 and the adapter 3, the outlet part 22 first enters the outer retaining ring 331. At this stage, the outer retaining ring 331 can assist the alignment between the first tube 321 and the outlet part 22. Then, the end of the outlet part 22 contacts the guide rib 333 and moves along the guide rib 333. The guide rib 333 acts on the end of the outlet part 22 and guides it to engage with the first tube 321. Finally, the end of the outlet part 22 enters the inner retaining ring 332 and moves downward to the position where the outlet part 22 abuts against the outer retaining ring 331 and the guide rib 333 in the first direction. That is, the first step surface 221 abuts against the outer retaining ring 331 in the first direction, and the second step surface 222 abuts against the guide rib 333 in the first direction. At this time, the outlet part 22 no longer moves downward and is thus positioned, and the docking is completed. The inner retaining ring 332 serves a dual function: alignment and forming an overflow prevention zone 34. When the connection is complete and ink is being added, the outlet portion 22, the outer retaining ring 331, and the guide rib 333 all abut against each other in the first direction, ensuring the connection stability between the adapter 3 and the ink container 2. Furthermore, a gap exists between the outlet portion 22's first-direction end and the substrate 31, forming the overflow prevention zone 34. The abutment between the first step surface 221 and the second step surface 222 of the outlet portion 22 and the outer retaining ring 331 and guide rib 333 improves the fit stability between the ink container 2 and the adapter 3. The guide rib 333 and the inner retaining ring 332 suppress the tilt of the ink container 2 relative to the first direction. Even if a small amount of ink leakage occurs due to the tilt of the ink container 2, it is confined within the overflow prevention zone 34, facilitating cleaning and preventing contamination of other parts of the ink container 2 and the adapter 3.

[0055] See Figure 8-9 Preferably, the ink cartridge refilling tool of this embodiment further includes a support member 4 for fixing the ink cartridge 1 when refilling ink. The support member 4 has a flat support surface 41, which may or may not have a hollow structure. In this embodiment, it has a hollow structure (see...). Figure 9 To reduce the overall weight of the support member 4, the support member 4 has at least one receiving groove 42 for accommodating a portion of the ink cartridge 1. Specifically, see [link to relevant documentation]. Figure 1 , 2 The recessed portion 116 at least partially overlaps with the support member 4 in the first direction. In the first direction, the rear wall 115 overlaps with the receiving groove 42, that is, in the first direction, the receiving groove 42 extends beyond the recessed portion 116 in height. Since the gas-liquid exchange section 120 is located near the rear wall 115 of the ink cartridge 1, setting the support member 4 to cooperate with the end of the ink cartridge 1 near the rear wall 115 helps to improve the support stability and facilitates the miniaturization of the support member 4. Furthermore, considering the presence of the recessed portion 116 at the aforementioned end, setting the receiving groove 42 of the support member 4 to accommodate a portion of one end of the ink cartridge 1 and extending beyond the recessed portion 116 in height further ensures the stability of the cooperation with the end of the ink cartridge 1, which is beneficial for maintaining the cooperation posture between the ink filling container 2 and the adapter 3 and the ink cartridge 1 and preventing ink leakage.

[0056] Preferably, in the third direction, the second wall 118 at least partially overlaps with the receiving groove 42, that is, the second wall 118 partially overlaps with the receiving groove 42, or the second wall 118 completely overlaps with the receiving groove 42. In this embodiment, it is preferable that the second wall 118 overlaps with the receiving groove 42, that is, in the third direction, the second wall 118 is completely located within the receiving groove 42. In the third direction, the first wall 117 at least partially overlaps with the receiving groove 42, that is, the first wall 117 partially overlaps with the receiving groove 42, or the first wall 117 completely overlaps with the receiving groove 42.

[0057] Preferably, in the first direction, the support surface 41 is flush with the top wall 111, that is, the support surface 41 and the top wall 111 are located on the same plane, making the support for the ink cartridge 1 more stable. In the third direction, the top wall 111 partially overlaps with the receiving groove 42 or does not overlap at all, that is, the top wall 111 is partially located inside the receiving groove 42, or the top wall 111 is completely located outside the receiving groove 42.

[0058] See Figure 8Preferably, the inner side of the receiving groove 42 further includes two opposing side baffles 421 in a second direction, the distance between the two side baffles 421 in the second direction being not less than the distance between the two side walls 113 in the second direction, and the second direction being orthogonal to the first direction and the third direction. The inner side of the receiving groove 42 also includes a rear baffle 422 that cooperates with the rear wall 115. The inner side of the receiving groove 42 also includes a lower support wall 423 that cooperates with the first wall 117 and / or the second wall 118. The side baffles 421 are used to cooperate with the two side walls 113 of the ink cartridge 1, thereby limiting the ink cartridge 1 in the second direction; the rear baffle 422 is used to cooperate with the rear wall 115 of the ink cartridge 1, thereby limiting the ink cartridge 1 in the third direction; and the lower support wall 423 is used to cooperate with the first wall 117 and / or the second wall 118 of the ink cartridge 1, thereby limiting the ink cartridge 1 in the first direction. The above configuration improves the support stability of the ink cartridge 1.

[0059] Furthermore, the side wall 421 includes two opposing first side walls 4211 and two opposing second side walls 4212. In a second direction, the distance between the two first side walls 4211 is less than the distance between the two second side walls 4212. The rear wall 422 includes a first rear wall 4221 and a second rear wall 4222. In a third direction, the first rear wall 4221 is connected between the two first side walls 4211, and the second rear wall 4222 is connected between the first side walls 4211 and the second side walls 4212. The lower support wall 423 includes a first lower support wall 4231, a second lower support wall 4232, and a third lower support wall 4233. In a first direction, the first lower support wall 4231 and the second lower support wall 4232 are flush, and the third lower support wall 4233 is lower than the first lower support wall 4231 and the second lower support wall 4232. The first lower support wall 4231 is connected between the first rear baffle wall 4221 and the first side baffle wall 4211. The second lower support wall 4232 is connected between the second rear baffle wall 4222 and the second side baffle wall 4212. The third lower support wall 4233 is located between the two second lower support walls 4232.

[0060] In this embodiment, ink cartridge 1 comes in two sizes, with the black ink cartridge and the color ink cartridge having different capacities. Therefore, the two types of ink cartridge 1 have different dimensions in the second direction. The black ink cartridge is thicker in the second direction. (See reference...) Figure 10 When the black ink cartridge is supported by the support member 4, it rests on the two second lower support walls 4232. The two side walls 113 of the black ink cartridge mate with the second side baffles 4212, and the rear wall 115 of the black ink cartridge mates with the two second rear baffles 4222. The color ink cartridge has a smaller thickness in the second direction. (See reference...) Figure 11When the color ink cartridge is supported by the support member 4, the color ink cartridge is placed on the first lower support wall 4231, the two side walls 113 of the color ink cartridge cooperate with the first side baffle wall 4211, and the rear wall 115 of the color ink cartridge cooperates with the first rear baffle wall 4221. The above-mentioned configuration of the support member 4 allows it to be adapted for use with two sizes of ink cartridges 1, increasing the versatility of the support member 4.

[0061] In this embodiment, the support member 4 is a fixed structure. Specifically, the support member 4 can be manufactured in one piece. The support member 4 can be a plastic part, manufactured by one-piece injection molding.

[0062] This embodiment also provides a method for using an ink cartridge refill tool, including the following steps:

[0063] S1: Place ink cartridge 1 and support member 4: Place ink cartridge 1 with the joint cavity 121 facing upward, that is, place ink cartridge 1 with the top wall 111 facing downward and the bottom wall 112 facing upward, and place support member 4 at one end where the recess 116 of ink cartridge 1 is located to support ink cartridge 1.

[0064] S2: Install adapter 3: Insert the second tube 322 of adapter 3 into the connecting cavity 121, abutting against the movable valve core 123 and communicating with the ink cavity 122. Engage the protrusion 3611 of adapter 3 with the locking protrusion 119 of ink cartridge 1. Specifically, insert the second tube 322 of adapter 3 into the connecting cavity 121, abutting against the movable valve core 123 and communicating with the ink cavity 122. The lower end of the second tube 322 presses down on the movable valve core 123, causing the movable valve core 123 to move downward, thus communicating the connecting cavity 121 with the ink cavity 122. Simultaneously, the protrusion 3611 of the adapter 3 engages with the locking protrusion 119 of the ink cartridge 1. Specifically, by pressing the adapter 3 downwards, the protrusion 3611 on the engaging arm 361 moves downwards past the locking protrusion 119. During this process, the two engaging arms 361 deform relative to each other in a second direction and move in opposite directions. After the protrusion 3611 has completely passed the locking protrusion 119, the deformation of the engaging arm 361 returns to normal, and the two engaging arms 361 move closer to each other in a second direction, so that the protrusion 3611 engages with the locking protrusion 119. During the above-mentioned force application process, the user can press their finger on the outer pressure plate 38 to apply downward force, thereby pressing the adapter 3 down and engaging the protrusion 3611 with the locking protrusion 119.

[0065] S3: Install ink container 2: Insert the outlet portion 22 of ink container 2 downward into the retaining portion 33 of adapter 3. The first tube 321 of adapter 3 passes through the outlet portion 22 and communicates with the ink storage chamber 21 of ink container 2. Specifically, when the outlet portion 22 of ink container 2 is inserted downward into the retaining portion 33 of adapter 3, the first step surface 221 of outlet portion 22 abuts against the outer retaining ring 331 of retaining portion 33 in the first direction, the second step surface 222 of outlet portion 22 abuts against the guide rib 333 of retaining portion 33 in the first direction, and the end of outlet portion 22 in the first direction is inserted into the inner retaining ring 332 of retaining portion 33. A gap portion is formed between the end of outlet portion 22 in the first direction and the base plate 31 of adapter 3. The gap portion is limited between the first tube 321 and the inner retaining ring 332 to form an overflow prevention zone 34. At the same time, the first tube 321 of the adapter 3 is inserted into the outlet 22 and pierces the self-sealing valve 23 inside the outlet 22 upward, so that the first tube 321 is connected to the ink storage chamber 21 of the ink container 2.

[0066] After installation, the ink container 2 forms a fluid channel with the ink chamber 122 of the ink cartridge 1 via the adapter 3. In this embodiment, the flow path 32 has two channels, namely, two channels are provided in both the first tube 321 and the second tube 322. One channel is for ink to pass through, and the other channel is for airflow, thus increasing the ink filling efficiency. The two channels have a height difference in the first direction, which facilitates the flow of ink and gas in the two channels respectively. Figure 7 The left arrow indicates the direction of gas flow, and the right arrow indicates the direction of ink flow. Ink can also be quickly output from the ink container 2 by squeezing the ink storage chamber 21.

[0067] After ink filling is complete, first pull the ink container 2 out of the adapter 3. Then, press the two operating arms 362 on the adapter 3 to deform the two operating arms 362 in the second direction and move them towards each other, that is, the distance between the two operating arms 362 in the second direction decreases. Since the operating arms 362 and the locking arms 361 are connected to each other, the two locking arms 361 move away from each other in the second direction, that is, the distance between the two locking arms 361 in the second direction increases. At this time, apply an upward force to the adapter 3 so that the protrusion 3611 on the locking arm 361 moves upward past the locking protrusion 119. After the protrusion 3611 disengages from the locking protrusion 119, release the operating arm 362, and the deformation of the operating arm 362 and the locking arm 361 returns to normal. After the second tube 322 of the adapter 3 disengages from the movable valve core 123, the movable valve core 123 is reset upward under the action of the elastic member 124, thereby closing the connection between the engagement cavity 121 and the ink cavity 122.

[0068] This invention, by providing a retaining section on the adapter, guides the connection between the first tube and the outlet section, suppressing the tilt of the ink filling container relative to the first direction, and improving the connection stability between the adapter and the ink filling container. This makes the ink filling process easier to operate and less prone to ink leakage. This invention also provides stable support for the ink cartridge through a support member, eliminating the need for manual alignment and straightening by the user, thus facilitating use.

[0081] See Figure 15 When folding the support member 4, the cardboard is folded sequentially along the first fold line 431, the second fold line 432 and the third fold line 433, each folding about 90 degrees. The -X side is folded upward about 90 degrees along the fourth fold line 434, and the +X side is folded upward about 90 degrees along the fifth fold line 435. Then, the first insertion part 461 and the third insertion part 463 are inserted and fixed, and the second insertion part 462 and the fourth insertion part 464 are inserted and fixed.

[0082] See Figure 12-14After folding, a support surface 41 is formed in the portion between the third fold line 433 and the first cutting line 451 and the second cutting line 452. A lower support wall 423 is formed in the middle of the support surface 41 in the X direction. A rear baffle 422 is formed between the first fold line 431, the first insertion part 461, the second insertion part 462 and the +Y edge of the support member 4. One side baffle 421 is formed between the first cutting line 451, the fourth fold line 434, the third insertion part 463 and the -X edge of the support member 4.
