Description

Technical Field

[0001] This utility model relates to the field of printing equipment, and in particular to an ink cartridge with good ink absorption performance. Background Technology

[0002] With the development of technology, portable inkjet printers have emerged to meet people's needs. Portable inkjet printers are small, lightweight, and easy to carry. They support wireless connections to computers, mobile phones, or tablets via Bluetooth, Wi-Fi, and other methods, and can be battery-powered to meet immediate printing needs. Their core advantage lies in eliminating the dependence on fixed locations inherent in traditional printers, making them suitable for mobile offices, education, and other scenarios.

[0003] Inkjet printers typically include a printhead, ink cartridge, doctor blade, and ink absorption cartridge. After printing, a small amount of ink may remain on the printhead. The doctor blade scrapes off the remaining ink, and the absorbent cotton in the ink absorption cartridge absorbs it.

[0004] Traditional inkjet printers are relatively large, with ample internal space and a large ink cartridge. Correspondingly, the ink capacity of the cartridge is also relatively large. Furthermore, traditional inkjet printers are typically used in a fixed location, with the cartridge in a stable position. Portable inkjet printers, on the other hand, are smaller in size, with less internal space. The ink cartridges and absorbent pads inside are also smaller than those in traditional inkjet printers, resulting in a smaller ink capacity. Due to their portability, portable inkjet printers are frequently subjected to vibration or placed off-center. Slow ink absorption can cause unabsorbed ink on the absorbent pad to drip onto other parts of the printer's interior, causing contamination.

[0005] Using a fast-absorbing ink cotton can prevent the above situation from occurring. However, fast-absorbing ink cotton usually has poor ink retention. Since the ink cotton in portable inkjet printers is small, it is easy to become saturated during use. When the ink cotton is saturated, it is also prone to dripping ink due to its poor ink retention and vibration or non-horizontal placement.

[0006] Slow-absorption materials suffer from dynamic leakage due to absorption delays, while fast-absorption materials cause secondary contamination due to poor ink retention. This has become a key technical bottleneck restricting the reliability of portable inkjet printers. Utility Model Content

[0007] The purpose of this invention is to solve one of the above-mentioned defects and provide an ink cartridge with good ink absorption performance.

[0008] The objective of this utility model is achieved through the following means:

[0009] An ink-absorbing cartridge with good ink absorption performance includes a cartridge body and an ink-absorbing cotton placed inside the cartridge body. The ink-absorbing cotton is used to absorb residual ink from the printhead. The ink-absorbing cotton includes an ink-absorbing layer and an ink-storing layer. The ink-absorbing layer is placed on top of the ink-storing layer, and the lower end of the ink-absorbing layer is attached to the upper end of the ink-storing layer. The ink-absorbing layer is used to quickly absorb ink, and the ink-storing layer is used to extract and store the ink absorbed by the ink-absorbing layer.

[0010] As a preferred embodiment, a connecting structure is provided between the ink-absorbing layer and the ink-storing layer to increase the contact area between them.

[0011] As a preferred embodiment, the connection structure includes a connecting block disposed at the lower end of the ink-absorbing layer and a connecting groove disposed at the upper end of the ink-storing layer. The connecting block is used to insert into the connecting groove and fit against the inner wall of the connecting groove.

[0012] As a preferred embodiment, the connecting block is a rectangular block, and the connecting groove is a rectangular groove.

[0013] As a preferred embodiment, the connecting groove is a dovetail groove, the shape of the connecting block matches the dovetail groove, and the ink absorption layer and the ink storage layer are fixedly connected to the connecting groove through the connecting block.

[0014] As a preferred embodiment, the ink-absorbing cotton also includes a leak-proof layer, which is recessed inward to form a receiving groove for accommodating the ink-absorbing layer and the ink-storing layer. The ink-absorbing layer and the ink-storing layer are disposed in the receiving groove, and the periphery of the ink-absorbing layer is in contact with the leak-proof layer.

[0015] As a preferred embodiment, the density of the leak-proof layer is the same as the material of the ink storage layer.

[0016] As a preferred embodiment, both the ink-absorbing layer and the ink-storing layer are sponges, with the density of the ink-absorbing layer being less than or equal to 20 kg / m³ and the density of the ink-storing layer being greater than or equal to 30 kg / m³.

[0017] The beneficial effects of this utility model are as follows: by designing the ink-absorbing cotton as a double-layer structure, the upper ink-absorbing layer quickly absorbs the ink, while the lower ink-storing layer with strong ink-storing capacity extracts and stores the ink in the ink-absorbing layer. This not only avoids dynamic leakage caused by delayed ink absorption, but also avoids secondary pollution caused by poor ink-locking ability. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] To facilitate understanding, the present invention will now be described in further detail with reference to specific implementation examples, but this is not intended to limit the present invention.

[0029] Example 1, as Figure 1-2 As shown, this utility model discloses an ink-absorbing cartridge with good ink absorption performance. The ink-absorbing cartridge includes a cartridge body 10 and an ink-absorbing cotton 20 disposed inside the cartridge body 10. The ink-absorbing cotton 20 is used to absorb residual ink from the printhead. The ink-absorbing cotton 20 is composed of an ink-absorbing layer 21 and an ink-storing layer 22. The ink-absorbing layer 21 is disposed at the upper end of the ink-storing layer 22, and the lower end of the ink-absorbing layer 21 is attached to the upper end of the ink-storing layer 22. The ink-absorbing layer 21 is used to quickly absorb ink, and the ink-storing layer 22 is used to extract and store the ink absorbed by the ink-absorbing layer 21.

[0030] Both the ink-absorbing layer 21 and the ink-storing layer 22 are sponges. The density of the ink-absorbing layer 21 is less than or equal to 20 kg / m³, and the density of the ink-storing layer 22 is greater than or equal to 30 kg / m³.

[0031] The principle of this invention is as follows: Ink is first absorbed by the macroporous sponge and temporarily stored in its pores (relying on liquid wettability). The lower microporous sponge, through stronger capillary force, gradually draws the ink from the upper sponge's pores into its own pores until a balance between capillary force and gravity is reached. Most of the ink accumulates in the lower microporous sponge, while the upper macroporous sponge, due to its weaker ink-holding capacity, gradually dries out. Gradient absorption is achieved through a combination of materials of different densities. The low-density ink-absorbing layer 21 quickly absorbs the ink, and then the lower high-density ink-storing layer 22 locks in the absorbed ink.

[0032] In this embodiment, the ink-absorbing layer 21 and the ink-storing layer 22 are bonded together with adhesive. The thickness ratio of the ink-absorbing layer 21 to the ink-storing layer 22 is 1:3. In practical applications, the thickness ratio of the ink-absorbing layer 21 to the ink-storing layer 22 can be adjusted according to the actual amount of residual ink in the portable inkjet printer.

[0033] Example 2, as Figure 3 As shown, the difference between this embodiment and the above embodiment is that a connection structure is provided between the ink-absorbing layer 21 and the ink-storing layer 22.

[0034] In this embodiment, the connection structure includes a connecting block 211 disposed at the lower end of the ink-absorbing layer 21 and a connecting groove 221 disposed at the upper end of the ink storage layer 22. The connecting block 211 is a rectangular connecting block 211, and the connecting groove 221 is a rectangular connecting groove 221. The connecting block 211 is used to insert into the connecting groove 221 and fit against the inner sidewall of the connecting groove 221, thereby increasing the contact area between the ink-absorbing layer 21 and the ink storage layer 22, improving the efficiency of the ink storage layer 22 in drawing ink from the ink-absorbing layer 21, and preventing the ink-absorbing layer 21 from becoming saturated quickly.

[0035] Example 3, as Figure 4 As shown, the difference between this embodiment and Embodiment 2 is that the connecting groove 221 is a dovetail groove, and the shape of the connecting block 211 matches the dovetail groove. The ink-absorbing layer 21 and the ink-storing layer 22 are fixedly connected to the connecting groove 221 through the connecting block 211. The ink-absorbing layer 21 and the ink-storing layer 22 are bonded with adhesive. However, the adhesive can block some pores at the lower end of the ink-absorbing layer 21 and the upper end of the ink-storing layer 22, affecting the efficiency of the ink-storing layer 22 in drawing ink from the ink-absorbing layer 21. Using a dovetail-shaped tenon and mortise structure for connection instead of adhesive achieves a tight fit between the ink-absorbing layer 21 and the ink-storing layer 22, reducing costs and avoiding the impact of adhesive on the efficiency of the ink-storing layer 22 in drawing ink from the ink-absorbing layer 21. Simultaneously, it increases the contact area between the ink-absorbing layer 21 and the ink-storing layer 22.

[0036] Example 4, as Figure 5 As shown, the difference between this embodiment and embodiment three is that the cross-section of the connecting block 211 is arc-shaped, and the shape of the connecting groove 221 matches that of the connecting block 211, further increasing the contact area between the ink-absorbing layer 21 and the ink-storing layer 22.

[0037] Example 5, such as Figure 6 As shown, the difference between this embodiment and embodiment three is that the ink-absorbing cotton 20 is composed of an ink-absorbing layer 21, an ink-storing layer 22 and a leak-proof layer 23. The leak-proof layer 23 is recessed inward to form a receiving groove for accommodating the ink-absorbing layer 21 and the ink-storing layer 22. The ink-absorbing layer 21 and the ink-storing layer 22 are disposed in the receiving groove, and the periphery of the ink-absorbing layer 21 is in contact with the leak-proof layer 23.

[0038] Because the ink-absorbing layer 21 has poor ink-locking ability, when the ink-absorbing cotton 20 is placed vertically, ink can easily seep out from the sides of the ink-absorbing layer 21 under the action of external force. A leak-proof layer 23 is provided to cover the sides of the ink-absorbing layer 21. In this embodiment, the density of the leak-proof layer 23 is the same as the density of the ink storage layer 22. The ink-locking ability of the leak-proof layer 23 prevents ink from leaking out from the sides of the ink-absorbing layer 21.

[0039] In this embodiment, the leak-proof layer 23 and the ink storage layer 22 are separately arranged. The leak-proof layer 23 is also a sponge and has the same density as the ink storage layer 22.

[0040] Example 6, as Figure 7 As shown, the difference between this embodiment and embodiment five is that the leak-proof layer 23 and the ink storage layer 22 are integrally formed, which simplifies the production process and saves costs.

[0041] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
