Description

Technical Field

[0001] This utility model relates to the field of ink cartridge technology, specifically to a split-type replaceable ink cartridge. Background Technology

[0002] With the popularization of inkjet printing technology, inkjet printers have become an indispensable device in offices and homes. However, the traditional inkjet printer cartridge design has some significant limitations, affecting the user experience and cost-effectiveness. Traditional cartridges usually adopt an integrated design, integrating ink with precision components such as printheads and circuit boards.

[0003] While this design offers certain conveniences in manufacturing and installation, it also brings about a series of problems:

[0004] When the ink runs out, the entire ink cartridge must be replaced, even though other components such as the printhead and circuit board can still be used. This one-time replacement method results in a large waste of resources.

[0005] Replacing an entire ink cartridge is costly, especially for users who print frequently. Over the long term, the cost of replacing ink cartridges can become a significant expense, increasing the financial burden on users.

[0006] Furthermore, users cannot flexibly change to different colors or types of ink according to specific printing needs.

[0007] To address this, a separate, replaceable ink cartridge is proposed. Utility Model Content

[0008] The purpose of this utility model is to provide a split-type replaceable ink cartridge in order to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0010] A detachable replaceable ink cartridge includes an ink cartridge with multiple ink cavities on its surface. An ink cartridge body is inserted into each ink cavity. An internally threaded collar is fixedly installed on the bottom surface of the ink cartridge body. A threaded post is rotatably installed on the bottom surface of each ink cavity. An operating component is provided on the surface of the ink cavity and the surface of the threaded post, so as to drive the threaded post to rotate, which is used for the threaded engagement of the threaded post with the internally threaded collar to disassemble and install the ink cartridge body in the ink cavity.

[0011] Furthermore, after the ink tank body is inserted into the ink cavity, the internal threaded collar on the bottom surface of the ink tank body corresponds to the threaded post, and the threaded post and the internal threaded collar are threadedly inserted.

[0012] Furthermore, the operating component includes a first gear fixedly sleeved on the surface of the threaded column, and multiple sets of support frames are fixedly installed on the surface of the ink cavity. A rotating shaft is rotatably installed inside the multiple sets of support frames and on the bottom surface of the ink cavity. A second gear is fixedly sleeved on the surface of the rotating shaft, and the second gear meshes with the first gear. A knob is fixedly installed at the top end of the rotating shaft.

[0013] Furthermore, the surface of the ink cavity is provided with two sets of protruding ribs, and the surface of the ink tank body is provided with positioning grooves.

[0014] Furthermore, when the ink tank body is inserted into the ink cavity, the positioning groove on the surface of the ink tank body engages with the raised ribs on the surface of the ink cavity.

[0015] The beneficial effects of this utility model are as follows:

[0016] By inserting the ink tank body into the ink cavity on the surface of the ink cartridge, the inner threaded collar on the bottom surface of the ink tank body corresponds to the end of the threaded post. The operating component drives the threaded post to rotate, and the threaded post and the inner threaded collar are inserted into each other. This allows the inner threaded collar and the ink tank body to move vertically downwards within the ink cavity, achieving complete insertion of the ink tank body into the ink cavity. When disassembling the ink tank body, the operating component is rotated in the opposite direction, causing the threaded post to rotate in the opposite direction. This causes the inner threaded collar to move vertically along the threaded post, thereby allowing the ink tank body to move vertically within the ink cavity for disassembly.

[0027] like Figures 1 to 5As shown, a split-type replaceable ink cartridge includes an ink cartridge 1. The surface of the ink cartridge 1 has multiple ink cavities 2, and an ink tank body 3 is inserted and installed in the ink cavity 2. An internal threaded collar 4 is fixedly installed on the bottom surface of the ink tank body 3. A threaded post 5 is rotatably installed on the bottom surface of the ink cavity 2. An operating component 6 is provided on the surface of the ink cavity 2 and the surface of the threaded post 5, so that the threaded post 5 is driven to rotate by the operating component 6, and the threaded engagement between the threaded post 5 and the internal threaded collar 4 is used to disassemble and install the ink tank body 3 in the ink cavity 2. More specifically, when installing the ink tank body 3, the ink tank body 3 is inserted into the ink cavity 2 on the surface of the ink cartridge 1, so that the end of the internal threaded collar 4 on the bottom surface of the ink tank body 3 corresponds to the end of the threaded post 5. The operating component 6 drives the threaded post 5 to rotate, and the threaded post 5 is inserted into the internal threaded collar 4, thereby causing the internal threaded collar 4 and the ink tank body 3 to move vertically downward in the ink cavity 2, so that the ink tank body 3 is completely inserted into the ink cavity 2. When disassembling the ink tank body 3, the operating component 6 is rotated in the opposite direction to drive the threaded post 5 to rotate in the opposite direction, so that the internal threaded collar 4 moves vertically along the threaded post 5, thereby causing the ink tank body 3 to move vertically in the ink cavity 2, and the ink tank body 3 is disassembled.

[0028] After the ink tank body 3 is inserted into the ink cavity 2, the internal threaded collar 4 on the bottom surface of the ink tank body 3 corresponds to the threaded post 5, and the threaded post 5 and the internal threaded collar 4 are threadedly inserted. More specifically, the ink tank body 3 can be fixed by the surface threading of the internal threaded collar 4 and the threaded post 5.

[0029] The operating component 6 includes a first gear 601 fixedly sleeved on the surface of the threaded post 5, and multiple sets of support frames 602 fixedly installed on the surface of the ink cavity 2. A rotating shaft 603 is rotatably installed inside the multiple sets of support frames 602 and on the bottom surface of the ink cavity 2. A second gear 604 is fixedly sleeved on the surface of the rotating shaft 603, and the second gear 604 meshes with the first gear 601. A knob 605 is fixedly installed at the top end of the rotating shaft 603. More specifically, by rotating the knob 605, the rotating shaft 603 and the second gear 604 are rotated, which in turn drives the first gear 601 and the threaded post 5 to rotate. The ink tank body 3 is disassembled and installed in the ink cavity 2 by the internal threaded collar 4 on the bottom surface of the ink tank body 3 sleeved on the end of the threaded post 5.

[0030] The surface of the ink cavity 2 is provided with two sets of protruding ribs 21, and the surface of the ink tank body 3 is provided with a positioning groove 31. More specifically, the positioning groove 31 corresponds to the protruding ribs 21, so that the ink tank body 3 can be guided to be inserted into the interior of the ink cavity 2.

[0031] When the ink tank body 3 is inserted into the ink cavity 2, the positioning groove 31 on the surface of the ink tank body 3 engages with the raised rib 21 on the surface of the ink cavity 2. More specifically, the engagement of the positioning groove 31 and the raised rib 21 enhances the stability of the ink tank body 3 during installation, preventing it from shaking or shifting during use.

[0032] In summary: When installing the ink tank body 3, insert the ink tank body 3 into the ink cavity 2 on the surface of the ink cartridge 1, so that the end of the internal threaded collar 4 on the bottom surface of the ink tank body 3 corresponds to the end of the threaded post 5. The operating component 6 drives the threaded post 5 to rotate, and the threaded post 5 is inserted into the internal threaded collar 4, thereby causing the internal threaded collar 4 and the ink tank body 3 to move vertically downward in the ink cavity 2, so that the ink tank body 3 is completely inserted into the ink cavity 2. When disassembling the ink tank body 3, the operating component 6 is rotated in the opposite direction to drive the threaded post 5 to rotate in the opposite direction, so that the internal threaded collar 4 moves vertically along the threaded post 5, thereby causing the ink tank body 3 to move vertically in the ink cavity 2, and the ink tank body 3 can be disassembled.
