AI Technical Summary
The sponge in existing printer ink cartridges ages during use, causing the pores to narrow, affecting ink absorption and flow, and making leakage more likely.
Adopting the structure of float, air bag and spring, the connection between the inside and outside of the ink cartridge is automatically adjusted through the sinking of the float and the rebound mechanism of the spring, thus preventing leakage and maintaining air pressure balance.
It effectively prevents leakage caused by sponge aging, avoids ink spillage during ink addition, and maintains the sealed state and air pressure balance inside the ink cartridge.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of printer ink cartridges, and more particularly to a leak-proof printer ink cartridge. Background Technology
[0002] Printer cartridges are key components in inkjet printers, used to store and supply ink. The cartridges contain ink, which is then sprayed onto the paper through the print head to complete the printing task. Their quality directly affects print quality; choosing the right cartridge ensures vibrant colors and clear text in printed documents or images.
[0003] In current technology, most printer ink cartridges have a sponge inside. However, the sponge inside the cartridge will age and shrink as it is used, causing the internal channels to narrow and affecting ink absorption. Furthermore, the aging sponge can prevent ink from flowing properly, resulting in leakage and affecting the use of the product. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a leak-proof printer ink cartridge.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a leak-proof printer ink cartridge, comprising a shell, a top cover fixedly connected to the top of the shell by bolts, a groove formed on the top of the top cover, a top plate disposed inside the groove, a through rod fixedly connected to the bottom of the top plate, and multiple through rods, each through rod having a connecting rod fixedly connected to its outer wall, a sleeve disposed inside the shell, a limiting groove formed on the outer wall of the sleeve, and multiple limiting grooves, a spring fixedly connected to the bottom of the top plate, a spring groove formed on the bottom of the inner wall of the groove, and multiple through grooves, a float disposed inside the sleeve, and an air bladder disposed on the top of the float.
[0006] As a further description of the above technical solution:
[0007] Multiple through rods pass through multiple through slots respectively, and multiple connecting rods are all C-shaped. Both ends of the connecting rods pass through the extension of the limiting slot to the inside of the sleeve. The bottom of the spring is fixedly connected to the bottom of the inner wall of the spring slot.
[0008] As a further description of the above technical solution:
[0009] A top rod is fixedly connected to the top of the float, and an air hole is opened at the bottom of the inner wall of the groove. The position of the top rod corresponds to the position of the air hole.
[0010] As a further description of the above technical solution:
[0011] The top of the housing is provided with an ink filling port, and a rubber stopper is installed inside the ink filling port.
[0012] As a further description of the above technical solution:
[0013] The bottom of the inner wall of the outer casing has an ink outlet, and there are multiple ink outlets. The bottom of the outer casing has a flow guide, which is connected to the multiple ink outlets.
[0014] As a further description of the above technical solution:
[0015] The bottom of the outer casing is fixedly connected to a guide port, which is located outside the flow guide port.
[0016] As a further description of the above technical solution:
[0017] The outer wall of the housing is provided with a mounting groove, and an observation window is installed inside the mounting groove. The mounting groove is made of transparent acrylic glass.
[0018] As a further description of the above technical solution:
[0019] The outer wall of the outer shell has anti-slip textures, and there are multiple anti-slip textures, which are distributed on the front and rear outer walls of the outer shell.
[0020] This utility model has the following beneficial effects:
[0021] 1. As the ink inside the casing decreases slowly with use, the float sinks along the sleeve. When the float is about to contact the bottom of the inner wall of the casing, the bottom of the float causes one end of multiple connecting rods inside the sleeve to move down. When the multiple connecting rods move down, the through rods and the top plate connected to them move down synchronously. Since the weight of the float is greater than the elastic force of multiple springs, the top plate moves down into the groove, sealing the air hole and blocking the communication between the inside and outside of the casing. At this time, the inside of the casing is in a closed state, which prevents leakage due to the aging of the sponge. At the same time, it can prevent the remaining ink inside from overflowing from the air hole due to shaking when adding ink. When adding ink to the inside of the casing, the float and air bladder move upward as the internal liquid level rises. Then, multiple springs rebound, causing the top plate to return to its position. The inside of the casing can then communicate with the outside through the air hole again, always maintaining the air pressure balance inside the casing. Attached Figure Description

Detailed Implementation
[0031] Reference Figure 1-7This utility model provides a leak-proof printer ink cartridge, comprising a housing 1, a top cover 2 fixedly connected to the top of the housing 1 by bolts, a groove 3 on the top of the top cover 2, a top plate 4 inside the groove 3, and multiple through rods 5 fixedly connected to the bottom of the top plate 4. Each through rod 5 has a connecting rod 6 fixedly connected to its outer wall, and the connecting rods 6 are C-shaped. A sleeve 7 is provided inside the housing 1, and multiple limiting grooves 8 are provided on the outer wall of the sleeve 7. Both ends of the connecting rods 6 extend through the limiting grooves 8 into the sleeve 7. Multiple springs 9 are fixedly connected to the bottom of the top plate 4. A spring groove 10 is provided at the bottom of the inner wall of the groove 3. There are multiple spring grooves 10. The bottom of the spring 9 is fixedly connected to the bottom of the inner wall of the spring groove 10. The bottom of the inner wall of the groove 3 is provided with a through groove 11, and there are multiple through grooves 11. Multiple through rods 5 pass through multiple through grooves 11 respectively. A float 12 is provided inside the sleeve 7. An air bag 13 is provided on the top of the float 12. A top rod 14 is fixedly connected to the top of the float 12. An air hole 15 is provided on the bottom of the inner wall of the groove 3. The position of the top rod 14 corresponds to the position of the air hole 15. The top rod 14 moves up with the float 12. When the ink is full, the top rod 14 will extend out from the air hole 15 and push the top plate 4 out slightly. At this time, the ink can be filled through the position of the top plate 4 until it is full, avoiding the situation of overfilling and overflow.
[0032] As the ink inside the outer casing 1 decreases slowly with use, the float 12 sinks down along the sleeve 7. When the float 12 is about to contact the bottom of the inner wall of the outer casing 1, the bottom of the float 12 causes one end of multiple connecting rods 6 inside the sleeve 7 to move down. When the multiple connecting rods 6 move down, the through rod 5 and the top plate 4 connected to them move down synchronously. Since the weight of the float 12 is greater than the elastic force of the multiple springs 9, the top plate 4 moves down into the interior of the groove 3, sealing the air hole 15 and blocking the communication between the interior and exterior of the outer casing 1. At this time, the interior of the outer casing 1 is in a closed state, which avoids leakage due to the aging of the sponge. At the same time, it can prevent the remaining ink inside from overflowing from the air hole 15 due to shaking when adding ink. When adding ink to the interior of the outer casing 1, the float 12 and the air bladder 13 move upward as the internal liquid level rises. Then the multiple springs 9 rebound, causing the top plate 4 to return to its position. The interior of the outer casing 1 can then communicate with the exterior again through the air hole 15, always maintaining the air pressure balance inside the outer casing 1.
[0033] The top of the outer casing 1 is provided with an ink filling port 16, and a rubber stopper 17 is installed inside the ink filling port 16. The bottom of the inner wall of the outer casing 1 is provided with an ink outlet 18, and there are multiple ink outlets 18. The bottom of the outer casing 1 is provided with a guide port 19, which is connected to multiple ink outlets 18. The bottom of the outer casing 1 is fixedly connected with a guide port 20, which is located outside the guide port 19.
[0034] The outer wall of the outer casing 1 is provided with a mounting groove 21, and an observation window 22 is installed inside the mounting groove 21. The mounting groove 21 is made of transparent acrylic glass, and the amount of ink inside the outer casing 1 can also be viewed through the observation window 22. The outer wall of the outer casing 1 is provided with anti-slip textures 23, and there are multiple anti-slip textures 23, which are distributed on the front and rear outer walls of the outer casing 1.
[0035] Working principle: As the ink inside the outer casing 1 decreases slowly with use, the float 12 sinks along the sleeve 7. When the float 12 is about to contact the bottom of the inner wall of the outer casing 1, the bottom of the float 12 drives the ends of multiple connecting rods 6 located inside the sleeve 7 to move down. When the multiple connecting rods 6 move down, the through rods 5 and the top plate 4 connected to them move down synchronously. Since the weight of the float 12 is greater than the elastic force of the multiple springs 9, the top plate 4 moves down into the interior of the groove 3, sealing the air hole 15 and blocking the communication between the interior and exterior of the outer casing 1. At this time, the interior of the outer casing 1 is in a closed state, avoiding leakage due to the aging of the sponge. At the same time, it can prevent the remaining ink inside from overflowing from the air hole 15 due to shaking when adding ink. When adding ink to the interior of the outer casing 1, the float 12 and the air bladder 13 move upward as the internal liquid level rises. Then the multiple springs 9 rebound, causing the top plate 4 to return to its position. The interior of the outer casing 1 can then communicate with the exterior again through the air hole 15, always maintaining the air pressure balance inside the outer casing 1.
