Description

Technical Field

[0001] This invention relates to an ink cartridge opening device and an ink cartridge refiller. Background Technology

[0002] Current printer ink cartridges are disposable, meaning they can only be used once. Once the ink inside is used up, the cartridge cannot be reused. The sheer number of discarded cartridges each year causes significant environmental pollution. Furthermore, printer ink cartridges have reusable value; simply throwing them away after the ink is used up wastes resources. Refilling the cartridge requires opening the cover, but the cover is often securely fastened, and existing tools often fail to open it easily. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defect that the top cover of the printer ink cartridge is not easy to open in the prior art, and to provide an ink cartridge opening device and an ink cartridge refiller.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A cartridge opening device is characterized in that the cartridge opening device includes an opening body and two latching parts, the two latching parts are respectively disposed on both sides of the opening body, and each of the two latching parts has a latching groove on the side wall facing the inner side of the opening body; a latching cavity for latching the top cover of the cartridge is formed between the two latching grooves and the opening body.

[0006] In this solution, two snap-fit ​​parts are arranged opposite each other on the cover opener body. The snap-fit ​​parts have opposite snap-fit ​​grooves, and the two opposite snap-fit ​​grooves form a snap-fit ​​cavity. The snap-fit ​​cavity is used to snap-fit ​​with the ink cartridge cover to open the ink cartridge cover, making the ink cartridge cover opening method convenient and simple.

[0007] Preferably, the slot is flush with one end face of the cover opener body and extends along the axial direction of the cover opener body to the other end of the cover opener body.

[0008] In this solution, the slot is located on the end face of one end of the cartridge opener body. When using the cartridge opener to insert the cartridge cover into the slot, the slot on the end face of the opener body can play a guiding role, making it easier for the cartridge cover to be inserted into the slot and improving the ease of use of the cartridge opener.

[0009] Preferably, the two slots are arranged opposite each other in the horizontal direction, and the two slots are respectively located at the middle position in the height direction of the latching part.

[0010] Preferably, the ink cartridge opening device further includes a limiting groove, the limiting groove and the snap-fit ​​portion are located at the same end of the opening device body, and the limiting groove extends from the end face of the opening device body along the axial direction of the opening device body into the opening device body and terminates in the opening device body.

[0011] In this solution, by setting a limiting groove on the cap opener body, the ink cartridge cap will not extend too far into the cap opener body during use, resulting in insufficient opening torque and making the ink cartridge cap difficult to open. The limiting groove makes it easier for users to open the ink cartridge cap, improving the ease of use of the ink cartridge cap opener. In addition, the limiting groove also serves as a guide when the ink cartridge cap is inserted.

[0012] Preferably, the ink cartridge opening device further includes a recess, which is disposed on the surface of the opening device body opposite to the latching portion.

[0013] In this solution, by setting a recess on the surface of the opener body and the snap-fit ​​part, when using the ink cartridge opener, the operator can press the recess with their finger to use the recess as a force point, thereby increasing the ease of use of the ink cartridge opener.

[0014] Preferably, the cartridge opening device includes an arc-shaped handle that extends from the opening body in a direction away from the latching portion.

[0015] Preferably, the width of the arc-shaped handle gradually decreases from the end closer to the lid opener body to the end farther away from the lid opener body.

[0016] In this solution, by setting the width of the arc-shaped handle to gradually decrease from the end closer to the cap opener body to the end farther away from the cap opener body, the comfort of holding is improved and the ease of use of the ink cartridge cap opening device is increased.

[0017] Preferably, the cartridge opening device includes a square handle that extends from the opening body in a direction away from the latching portion.

[0018] An ink cartridge refiller is characterized in that the ink cartridge refiller is provided with an ink cartridge opening device as described above.

[0019] In this solution, the ink cartridge opening device and the ink cartridge refiller are integrated into one unit. When refilling ink into the ink cartridge using the ink cartridge refiller, the ink cartridge cover can be opened using the ink cartridge opening device at the bottom of the ink cartridge refiller. This prevents the ink cartridge opening device from being lost and improves the ease of use and convenience of the ink cartridge refiller.

[0020] Preferably, the ink cartridge opening device is located at the bottom of the ink cartridge refiller.

[0021] In this solution, by placing the ink cartridge opening device at the bottom of the ink cartridge refiller, the impact of the ink cartridge opening device on the use of the ink cartridge refiller is reduced. In addition, placing the ink cartridge opening device at the bottom of the ink cartridge refiller helps to increase the opening torque of the ink cartridge opening device and improve the ease of use of the ink cartridge opening device.

[0022] The positive and progressive effects of this invention are as follows:

[0023] The ink cartridge opening device and ink cartridge refiller of the present invention feature two latching portions on the opening device body, each with a latching groove. These two grooves form a latching cavity that engages with the ink cartridge cover to open it, enabling the replacement of the cover and the refilling of ink into the cartridge. This allows the ink cartridge to be reused. Ink cartridge recycling protects the environment, reduces waste generation, and lowers consumer costs. Attached Figure Description

[0043] Ink cartridge 4 Detailed Implementation

[0044] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments.

[0045] like Figure 1 As shown, the present invention provides an ink cartridge opening device 2, which includes an opening device body 23 and two latching parts 27. The two latching parts 27 are respectively disposed on both sides of the opening device body 23, and each of the two latching parts 27 has a latching groove 21 on the side wall facing the inner side of the opening device body 23; a latching cavity for latching the ink cartridge cover 1 is formed between the two latching grooves 21 and the opening device body 23.

[0046] The cartridge opening device 2 also includes a limiting groove 22, which is located at the same end of the opening device body 23 as the locking part 27. The limiting groove 22 extends from the end face of the opening device body 23 along the axial direction of the opening device body 23 into the opening device body 23 and terminates inside the opening device body 23.

[0047] like Figure 1 As shown, the slot 21 is flush with one end face of the cover opener body 23 and extends along the axial direction of the cover opener body 23 to the other end of the cover opener body 23.

[0048] Two latching portions 27 are disposed opposite each other on both sides of the cap opener body 23, and two slots 21 of the same size are disposed opposite each other within the latching portions 27. A latching cavity is formed between the two slots 21 and the cap opener body 23. When the ink cartridge cap opener 2 is used to open the ink cartridge cover 1, the ink cartridge cover 1 is latched into the latching cavity so that the ink cartridge cap opener 2 can pry the ink cartridge cover 1 open. A limiting groove 22 is disposed between the slots 21 and the cap opener body 23. The depth of the limiting groove 22 can be set according to the protrusion on the ink cartridge cover 1. The limiting groove 22 is used to prevent the ink cartridge cover 1 from extending too far into the cap opener body 23, which would result in insufficient opening torque during use, making it difficult to open the ink cartridge cover 1. The limiting groove 22 makes it easier for users to open the ink cartridge cover 1 using the ink cartridge cap opener 2, improving the usability of the ink cartridge cap opener 2. The limiting groove 22 and the slot 21 extend from the same side end face of the cap opener body 23 along the axis of the cap opener body 23 into the interior of the cap opener body 23.

[0049] The two slots 21 are arranged opposite each other in the horizontal direction, and the two slots 21 are respectively located at the middle position in the height direction of the latching part 27.

[0050] The card slot 21 is located at the middle position in the height direction of the latching part 27. A latching part 27 of a certain thickness is provided at the lower end of the card slot 21 to enhance the strength of the card slot 21 and prevent the latching part 27 from being damaged due to insufficient strength when the ink cartridge cover 1 is pried.

[0051] like Figure 3 and Figure 5 As shown, the ink cartridge opening device 2 also includes a recess 26, which is disposed on the surface of the opening device body 23 opposite to the latching part 27.

[0052] The arc-shaped handle 24 has a recess 26, which is used by the user to press as a force point when opening the cover. The recess 26 can be circular in shape. This makes it easier for the user to apply force at the recess 26, thereby applying a greater torque to the ink cartridge opening device 2 to open the ink cartridge cover 1.

[0053] In this embodiment, the recess 26 can be circular. In other embodiments, the recess 26 can also be elliptical or other shapes that are convenient for finger pressing.

[0054] like Figure 2 , Figure 4 and Figure 5 As shown, the ink cartridge opening device 2 includes an arc-shaped handle 24, which extends from the opening device body 23 in a direction away from the latching portion 27.

[0055] The width of the arc-shaped handle 24 gradually decreases from the end closer to the lid opener body 23 to the end farther away from the lid opener body 23.

[0056] An arc-shaped handle 24 is fixedly connected to one end of the cap opener body 23. The arc-shaped handle 24 is convenient for users with small hands to grip and use. The arc-shaped handle 24 is widest at the end closest to the cap opener body 23, and its width gradually decreases as it moves away from the cap opener body 23. The arc-shaped handle 24 is fixedly connected to the rear end of the cap opener body 23, and the front end of the cap opener body 23 has an opening for a slot 21 and a limiting groove 22. When the ink cartridge cap opening device 2 is used to open the ink cartridge cover 1, the ink cartridge cover 1 extends from the opening at the front end of the cap opener body 23 into the slot 21, and the protrusion on the ink cartridge cover 1 engages in the limiting groove 22. As a result, the cap opener body 23 cannot continue to move forward due to the restriction of the limiting groove 22, and the user pries up the ink cartridge cover 1 by operating the arc-shaped handle 24.

[0057] like Figure 6 As shown, the ink cartridge opening device 2 includes a square handle 25, which extends from the opening device body 23 in a direction away from the latching portion 27.

[0058] A square handle 25 can also be fixedly connected to one end of the cap opener body 23. The square handle 25 is fixedly connected to the rear end of the cap opener body 23, and the width of the end of the square handle 25 near the cap opener body 23 and the end away from the cap opener body 23 is the same. The front end of the cap opener body 23 has an opening with a slot 21 and a limiting groove 22. When the ink cartridge cap opening device 2 is used to open the ink cartridge cover 1, the ink cartridge cover 1 is inserted into the slot 21 through the opening at the front end of the cap opener body 23, and the protrusion on the ink cartridge cover 1 is engaged in the limiting groove 22. Thus, the cap opener body 23 cannot continue to move forward due to the restriction of the limiting groove 22. The user can open the ink cartridge cover 1 by pulling the square handle 25.

[0059] The ink cartridge cover 1 has two ends with different widths along its length, the wider one being the first end and the narrower one the second end. The width of the first end is the same as the distance between the two slots 21 of the ink cartridge opening device 2, while the width of the second end is too small to be inserted into the slots 21. This design prevents the user from accidentally inserting the second end into the slots 21, which could damage the ink cartridge cover 1. When the ink cartridge opening device 2 is used to open the ink cartridge cover 1, the two slots 21 are guided and locked onto the cover body by the arc edge of the ink cartridge cover 1, pushing the ink cartridge opening device 2 towards the second end until the protruding part on the ink cartridge cover 1 is locked into the limiting groove 22. At this point, the ink cartridge opening device 2 is in place, and the ink cartridge opening device 2 opens the ink cartridge cover 1 in a direction away from the ink cartridge body, with the second end as the rotation axis.

[0060] The ink cartridge opening device 2 can also be used to open a regular ink cartridge 4, as long as the width of the regular ink cartridge cover 1 is the same as the distance between the two slots 21 of the ink cartridge opening device 2. After inserting the cover of the regular ink cartridge 4 into the slots 21 of the ink cartridge opening device 2, the ink cartridge cover 1 of the regular ink cartridge 4 can be opened using the ink cartridge opening device 2 of the present invention. When needed, the ink cartridge cover 1 of the regular ink cartridge 4 can also be replaced with the ink cartridge cover 1 of the present invention, thereby enabling ink to be injected into the regular ink cartridge 4.

[0061] like Figure 7 and Figure 8 As shown, the present invention also provides an ink cartridge refiller 3, which has an ink cartridge opening device 2 as described above.

[0062] The ink cartridge opening device 2 and the ink cartridge refiller 3 are designed as a single unit. When refilling ink cartridge 4 with ink cartridge refiller 3, the operator can open the ink cartridge cover 1 using the ink cartridge opening device 2 at the bottom of ink cartridge refiller 3, which avoids the ink cartridge opening device 2 from being lost and improves the ease of use and convenience of ink cartridge refiller 3.

[0063] The ink cartridge opening device 2 is located at the bottom of the ink cartridge refiller 3.

[0064] The ink cartridge opening device 2 is located at the bottom of the ink cartridge refiller 3. When using the ink cartridge refiller 3, the operator first uses the opening device 2 at the bottom of the ink cartridge refiller 3 to open the ink cartridge cover 1, and then uses the ink cartridge refiller 3 to inject ink into the ink cartridge 4, which has already had its cover 1 opened. The location of the opening device 2 at the bottom of the ink cartridge refiller 3 minimizes its impact on the use of the ink cartridge refiller 3. Furthermore, its location at the bottom of the ink cartridge refiller 3 helps increase the opening torque of the opening device 2, improving its ease of use.

[0065] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
