[0029] Reference Figures 1 to 5 An ink cartridge with stable ink supply includes a cartridge body 100 and a sponge body 200. The cartridge body 100 is provided with an ink chamber 110, a sponge chamber 120, and an ink supply hole 130. The ink supply hole 130 is connected to the sponge chamber 120, and the ink chamber 110 is connected to the sponge chamber 120. The sponge body 200 is provided between the sponge chamber 120 and the ink supply hole 130. Among them, the ink chamber 110 is divided into a front chamber 111 and a rear chamber 112, and the sponge chamber 120 is arranged between the front chamber 111 and the rear chamber 112. The front chamber wall of the sponge chamber 120 is provided with a front ink hole 140, and the front ink hole 140 connects the front chamber 111 and the sponge chamber 120. The rear chamber wall of the sponge chamber 120 is provided with a rear ink hole 150, and the rear ink hole 150 connects the rear chamber 112 and the sponge chamber 120; the ink in the front chamber 111 and the rear chamber 112 is respectively transported to the front and rear ends of the sponge body 200 through the front ink hole 140 and the rear ink hole 150.
[0030] The above-mentioned ink cartridge divides the ink chamber 110 into a front chamber 111 and a rear chamber 112, and the sponge chamber 120 is arranged between the front chamber 111 and the rear chamber 112. The front chamber wall and the rear chamber wall of the sponge chamber 120 are respectively provided with a front ink hole 140 and a rear ink hole 150, so that the ink in the front chamber 111 and the rear chamber 112 can be respectively transported to the front and rear ends of the sponge. Since there is ink supply at the front and rear ends of the sponge, the sponge can quickly replenish and absorb the ink, which can effectively ensure the stability of the ink supply.
[0031] In this embodiment, the sponge 200 includes two separate parts, namely a main sponge 210 and an ink supply sponge 220. The main sponge 210 is disposed in the sponge cavity 120, and the ink supply sponge 220 is disposed in the ink supply hole 130. With this structure, the sponge is divided into two parts, which avoids the need to manufacture a single piece of complex sponge. Furthermore, the main sponge 210 and the ink supply sponge 220 can be installed separately, reducing the difficulty of installation.
[0032] In this embodiment, the sponge chamber 120 is located above the ink supply hole 130. The lower end of the sponge chamber 120 communicates with the upper end of the ink supply hole 130. The lower end of the ink supply hole 130 serves as an ink supply port. Ink in the front chamber 111 and the rear chamber 112 is delivered to the front and rear ends of the lower portion of the main sponge 210 through the front ink hole 140 and the rear ink hole 150, respectively. A gap exists between the main sponge 210 and the ink supply sponge 220. With this structure, ink is primarily supplied to the front and rear ends of the lower portion of the main sponge 210. Gravity then allows the ink to flow toward the ink supply sponge 220. The gap between the main sponge 210 and the ink supply sponge 220 creates a barrier, ensuring a stable ink supply while preventing excessive upward ink penetration, thereby reducing residual ink.
[0033] In this embodiment, a partition 160 is provided between the lower end of the sponge chamber 120 and the upper end of the ink supply hole 130. The lower end of the main sponge 210 abuts against the upper end of the partition 160, and the upper end of the ink supply sponge 220 abuts against the lower end of the partition 160. With this structure, the partition 160 can maintain a stable distance between the main sponge 210 and the ink supply sponge 220.
[0034] In the embodiment, two partitions 160 are provided, which are arranged on the front and rear walls of the sponge cavity 120 respectively, so as to support and balance. Of course, it is conceivable that the partitions 160 are not limited to two, for example, they can also be a whole one, or more than two, and the specific configuration can be based on actual conditions.
[0035] In an embodiment, the cartridge body 100 is provided with an air inlet 170, which is connected to the upper end of the sponge chamber 120. The upper end of the front chamber 111 and the upper end of the rear chamber 112 are connected to each other. External air used to balance the air pressure in the ink cartridge can enter through the air inlet 170 and reach the upper end of the connected sponge chamber 120. After the ink in the front chamber 111 and the rear chamber 112 is supplied to the outside, the air then enters the front chamber 111 and the rear chamber 112 through the front ink hole 140 and the rear ink hole 150, thereby achieving air pressure balance. By configuring the upper end of the front chamber 111 and the upper end of the rear chamber 112 to be connected to each other, air can be supplemented between the front chamber 111 and the rear chamber 112. This can avoid an imbalance in the amount of gas entering the front ink hole 140 and the rear ink hole 150. The front chamber 111 and the rear chamber 112 can still ensure that the front chamber 111 and the rear chamber 112 have an evenly balanced amount of gas through the connection at the upper end.
[0036] In an embodiment, the box body 100 is provided with an air inlet channel 180, and the air inlet hole 170 is communicated with the upper end of the sponge cavity 120 through the air inlet channel 180. In some embodiments, the air inlet hole 170 can also be directly communicated with the upper end of the sponge cavity 120.
[0037] In the embodiment, the box body 100 includes a main shell 101 and an end cover 102. The main shell 101 is provided with a cavity with an opening facing upward. A partition wall is provided in the cavity. The partition wall divides the cavity into a front cavity groove 103, a rear cavity groove 104, and a sponge cavity groove 105. The notches of the front cavity groove 103, the rear cavity groove 104, and the sponge cavity groove 105 face upward. The end cover 102 is connected to the upper end of the shell and covers the notches of the front cavity groove 103, the rear cavity groove 104, and the sponge cavity groove 105. The end cover 102 and the front cavity groove 103, the rear cavity groove 104, and the sponge cavity groove 105 respectively enclose a front side cavity 111, a rear side cavity 112, and a sponge cavity 120. With the above structure, the front side cavity 111, the rear side cavity 112, and the sponge cavity 120 can be formed with a simple structure, which is easy to produce and implement.
[0038] In the embodiment, the partition wall includes a front wall 106, a rear wall 107, and a left wall 108. The right end of the front wall 106 is connected to the right side wall of the cavity, the front end of the left wall 108 is connected to the left end of the front wall 106, the left end of the rear wall 107 is connected to the rear end of the left wall 108, and the right end of the rear wall 107 is connected to the right side wall of the cavity. The front wall 106, the rear wall 107, the left wall 108, and part of the right side wall of the cavity enclose a sponge cavity 105. The front ink inlet 140 is provided in the front wall 106, and the rear ink inlet 150 is provided in the rear wall 107. With the above structure, the right side wall of the cavity can be used to enclose the sponge cavity 105 with the front wall 106, the rear wall 107, and the left wall 108, thereby simplifying the structure and facilitating improved cavity utilization.
[0039] In the embodiment, the ink supply hole 130 is provided in the main housing 101 and is located below the sponge cavity 105. The upper end of the ink supply hole 130 and the lower end of the sponge cavity 105 are interconnected, and the lower end of the ink supply hole 130 is the ink supply opening. The lower portion of the rear ink inlet 150 extends through the ink supply hole 130. With the above structure, since the lower portion of the rear ink inlet 150 extends through the ink supply hole 130, when the main housing 101 is produced by injection molding, the core of the ink supply hole 130 and the core of the main housing 101 can be used to form a "bump-through" structure to form the rear ink inlet 150. This simplifies the mold structure and facilitates processing. It is particularly suitable for situations where there is a lack of mold design space near the rear ink inlet 150. In the embodiment, there is more space in front of the front ink hole 140, so the front ink hole 140 can be ejected from the mold using a slanted top structure.
[0040] In an embodiment, the partition wall further includes a reinforcing rib 109, which is disposed between the left wall of the cavity and the left wall 108. The left end of the reinforcing rib 109 is connected to the left wall of the cavity, and the right end of the reinforcing rib 109 is connected to the left wall 108. The reinforcing rib 109 can increase the structural strength of the main housing 101, thereby reducing deformation of the ink cartridge.
[0041] In this embodiment, a communication gap is formed between the upper end of the reinforcing rib plate 109 and the end cap 102, and the communication gap connects the upper end of the front chamber 111 and the upper end of the rear chamber 112. By providing a communication gap between the upper end of the reinforcing rib plate 109 and the end cap 102, the upper end of the front chamber 111 and the upper end of the rear chamber 112 are connected, so that the balance air in the front chamber 111 and the rear chamber 112 can complement each other. The above structure is simple and easy to implement.
[0042] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0043] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
