Description

TECHNICAL FIELD

[0001] The utility model relates to a ink storage box for supplementing ink to ink cartridge, especially an ink supplementing box. BACKGROUND

[0002] In modern office and daily life, as an indispensable equipment, the disposable design of the core consumable ink cartridge of the printer has become a key pain point affecting printing experience and cost control. After the ink is depleted, it is difficult to continue printing and refill, which leads to multiple problems such as resource waste, environmental pollution and high use cost. From the perspective of resource utilization, the ink cartridge composed of a plastic shell, an ink storage sponge and a chip is abandoned as a whole even if part of the components still have use value due to the depletion of ink. Not only does it occupy limited landfill space, but the non-degradable plastic shell also becomes an important source of white pollution. If the residual ink is not properly treated, it may pollute water bodies and black and colored powders may exacerbate air particulate pollution. In terms of use cost, in high-frequency use scenarios (such as educational institutions), the frequent replacement of ink cartridges to maintain printing needs has become a significant economic burden that restricts printing needs for small enterprises and budget-sensitive groups.

[0019] In order to make the purpose, technical scheme and advantage of the utility model more clear and explicit, the utility model is further described in detail below in combination with specific implementation manners and with reference to the drawings.It should be explained that the embodiment of the utility model and the features in the embodiment can be combined mutually without conflict.

[0020] It is understood that the description is only exemplary, and is not intended to limit the scope of the utility model.

[0021] Some embodiments of the utility model are described below in combination with the drawings to provide a kind of.

[0022] Reference Figures 1-6 An ink refill cartridge includes a cartridge body 1, which stores ink 2. The cartridge body 1 has an opening on its upper side, and a cover 3 is sealed at the opening. The top surface of the cover 3 has an air inlet 5 sealed by a sealing film 4. The lower end of the cartridge body 1 has an ink outlet 6, and a sealing element 7 is sealed inside the ink outlet 6. An ink outlet channel 8 is provided inside the sealing element 7, and a self-sealing film 9 is provided inside the ink outlet channel 8, which is punctured only when in use. When refilling the ink cartridge, the ink outlet is inserted into the refill position of the ink cartridge, which punctures the self-sealing film. After the sealing film is torn off, the ink in the cartridge body is replenished into the ink cartridge through the ink outlet channel. This breaks through the traditional disposable design, realizes the multiple recycling of ink cartridges, significantly reduces the risk of environmental pollution, meets the needs of the circular economy, and at the same time, allows users to reduce the frequency of ink cartridge replacement, effectively solving the pain point of high consumable costs.

[0023] The bottom of the cartridge 1 is provided with an inclined surface 10 that slopes downward from the inner wall of the cartridge 1 toward the ink outlet 6. The ink outlet 6 is located at the lowest point of the cartridge 1. The ink will flow along the inclined surface 10 toward the ink outlet 6, ensuring that all the ink in the cartridge 1 can be gathered at the ink outlet 6 and finally replenished into the ink cartridge through the ink outlet channel 8, avoiding the waste of ink caused by a small amount of ink remaining in the cartridge 1.

[0024] An anti-detachment ring 11 is provided inside the ink outlet 6. The side wall of the seal 7 is provided with an annular groove 12 corresponding to the anti-detachment ring 11. The anti-detachment ring 11 is embedded in the annular groove 12. The seal 7 is made of silicone or other elastic materials. The seal 7 can be installed by directly pressing it into the ink outlet 6 through the equipment.

[0025] The sealing element 7 is provided with several arranged sealing rings 13 on the lower side of the annular groove 12. The sealing rings 13 are tightly fitted with the ink outlet 6. After the sealing element 7 is installed, the sealing rings 13 will be squeezed by the inner wall of the ink outlet 6, causing the sealing rings 13 to undergo slight deformation, thereby improving the sealing effect.

[0026] The top surface of the cover 3 is provided with an annular protrusion 14 on the outside of the air inlet 5. The sealing film 4 is fixed on the annular protrusion 14 by hot pressing. When the sealing film 4 is hot pressed, its shape will deform according to the shape of the annular protrusion 14, thereby increasing the contact area between the sealing film 4 and the annular protrusion 14, thereby improving the adhesion effect. The air inlet 5 is located inside the annular protrusion 14. Since the entire annular protrusion 14 is in contact with the sealing film 4, the air inlet 5 will naturally be sealed.

[0027] The top surface of the cover 3 is provided with several reinforcing protrusions 15 on the outer side of the annular protrusion 14. The sealing film 4 is fixed to the reinforcing protrusions 15 by hot pressing. The reinforcing protrusions 15 are similar in design principle to the annular protrusion 14. They are mainly designed to increase the contact area with the sealing film 4, thereby further improving the firmness of the bonding after hot pressing and preventing the sealing film 4 from easily falling off, which would cause ink to evaporate or spill out inside the box 1, resulting in ink waste.

[0028] This product can be used with a positioning device for fixing ink cartridges. The positioning device includes a base 16 and an ink filling positioning cover 17. The base 16 is used to fix and position the ink cartridge. The ink filling positioning cover 17 is provided with an ink filling nozzle 18. An ink filling needle 19 is installed in the center of the ink filling nozzle 18. When refilling ink, the ink outlet 6 is inserted into the ink filling nozzle 18. The ink filling needle 19 will puncture the self-sealing film 9 and then tear open the sealing film 4 to open the air inlet 5. At this time, the ink in the cartridge 1 flows into the ink cartridge through the ink filling needle 19.

[0029] Furthermore, the ink filling positioning cover 17 on the base 16 can be replaced with a drilling positioning cover 20. The drilling positioning cover 20 is provided with a positioning hole 21 for guiding the drill bit to process precisely. A copper sleeve 22 is installed in the positioning hole 21. The positioning hole 21 and the copper sleeve 22 are tightly fitted together. Before refilling the ink cartridge, a through hole for refilling ink needs to be machined in the ink cartridge with a drill bit. The function of the drilling positioning cover 20 is to ensure the accuracy of the drilling position and to prevent the ink cartridge from being damaged due to the user's unfamiliarity with drilling operations.
