[0037] In order to make the purpose, technical scheme and advantages of the utility model more clear and explicit, the utility model is further explained in detail below in combination with specific implementation manners and with reference to the drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0038] It is understood that the above description is only exemplary and is not intended to limit the scope of the utility model.

[0039] Some embodiments of the utility model are described below in combination with the drawings to provide a kind of.

[0040] With reference to Figures 1-20 A refill ink cartridge ink adding kit, the kit includes drilling assembly 1, positioning assembly 2 and ink injection assembly 3, drilling assembly 1 includes drill bit 5 driven by motor 4, positioning assembly 2 includes base 6 for fixing ink cartridge B, base 6 can alternatively install drill positioning cover 7 and ink injection positioning cover 8, drill positioning cover 7 is provided with positioning hole 9 for guiding drill bit 5 accurate processing, ink injection positioning cover 8 is provided with ink adding nozzle 10 corresponding to the position of drilling, ink injection assembly 3 includes box body 11 with ink stored inside, the upper end of box body 11 is provided with air inlet 12, the bottom of box body 11 is provided with ink outlet 13 matched with ink adding nozzle 10.

[0041] When drilling, the ink cartridge is fixed in the base 6, and then the drilling positioning cover 7 is assembled to drill, without professional skills, which can avoid improper operation damage to the ink cartridge, save the time and cost of returning to the manufacturer, solve the problem of time-consuming and expensive ink refilling, and introduce the pressure balance compensation design principle. When refilling ink, the drilling positioning cover 7 is replaced with the ink refilling positioning cover 8, the ink refilling needle 25 is inserted into the drilling hole of the ink cartridge, and an exhaust passage is formed between the ink refilling needle 25 and the drilling hole (the diameter of the drilling hole is slightly larger than the outer diameter of the ink refilling needle 25), ink is injected into the ink cartridge from the ink refilling needle 25 by gravity, and the air in the ink cartridge is discharged through the exhaust passage. The structure introduces the pressure balance compensation design principle, automatically adjusts the air pressure inside and outside the ink cartridge, and does not increase the pressure inside the ink cartridge by injecting ink into the ink cartridge by external pressure. The principle can avoid changes in the pressure of the ink cartridge, resulting in ink overflow or interruption of ink supply, break through the traditional disposable design, realize recycling of the ink cartridge, reduce environmental pollution, reduce the replacement frequency, and effectively solve the pain point of high cost of consumables.

[0042] The ink cartridge generally has single color (such as black) and color (such as 3 colors: cyan, magenta, and yellow). When black is refilled, the number of positioning holes 9 on the drilling positioning cover 7 is 1 and corresponds to the ink chamber where the black color is located. The ink refilling nozzle 10 on the ink refilling positioning cover 8 and the ink refilling needle 25 installed in the ink refilling nozzle 10 are also 1. When the color is refilled, the number of positioning holes 9 on the drilling positioning cover 7 is 3 and corresponds to the ink chamber where the color is located. The ink refilling nozzle 10 on the ink refilling positioning cover 8 and the ink refilling needle 25 installed in the ink refilling nozzle 10 are also 3. When refilling, the three colors are refilled respectively.

[0043] Further, the ink refilling positioning cover 8 is provided with a refilling mark D corresponding to the color of the refilled ink to reduce the occurrence of refilling errors. Correspondingly, the drilling positioning cover 7 also needs to be provided with a drilling mark C to prevent drilling errors and damage to the ink cartridge.

[0044] The base 6 is provided with a cavity 14 for fixing the ink cartridge. The left and right sides of the cavity 14 are symmetrically provided with first positioning parts 15, and the upper end surface of the first positioning part 15 is in abutment with the upper end flange of the ink cartridge (such as Figure 8 E is the flange on the ink cartridge, the height of the first positioning part 15 is higher than the height of the highest dimension of the ink cartridge, that is, after the ink cartridge is placed, the bottom of the ink cartridge is in a suspended state, so that the nozzle at the bottom of the ink cartridge is prevented from contacting the bottom of the base 6, thereby avoiding the condition that precise positioning cannot be achieved), and the front side and the rear side of the cavity 14 are respectively provided with second positioning parts 17 and third positioning parts 18.

[0045] Further, the first positioning part 15 is two parallel ribs, and an integral connecting wall 16 is arranged between the ribs on the side close to the ink cartridge. The first positioning part 15 and the connecting wall 16 form a “U” shaped structure. The upper end of the connecting wall 16 is flush with the top of the first positioning part 15, so as to increase the area of the top of the first positioning part 15, that is, to increase the area of the support for the flange of the ink cartridge. In addition, the connecting wall 16 also has the function of positioning the left and right sides of the ink cartridge.

[0046] The connecting wall 16, the second positioning part 17 and the third positioning part 18 need to be adjusted accordingly for different brands and models of ink cartridges.

[0047] For the ink cartridge without flange, a rib can be arranged at the bottom of the cavity 14 for contacting the bottom of the ink cartridge. The height of the rib needs to be greater than the height of the nozzle of the ink cartridge, so that the nozzle is in a suspended state, avoiding the vibration generated during the drilling operation from being transmitted to the nozzle and affecting it.

[0048] The drilling positioning cover 7 and the ink injection positioning cover 8 are respectively provided with a first error prevention plate 19 and a second error prevention plate 20 corresponding to the second positioning part 17. When the drilling positioning cover 7 and the ink injection positioning cover 8 are installed in an incorrect direction, the first error prevention plate 19 and the second error prevention plate 20 will abut against the third positioning part 18, so that the drilling positioning cover 7 and the ink injection positioning cover 8 cannot be installed.

[0049] The bottom edges of the drilling positioning cover 7 and the ink injection positioning cover 8 are respectively provided with a first positioning edge 21 and a second positioning edge 22. When the drilling positioning cover 7 or the ink injection positioning cover 8 is installed, the outer sides of the first positioning edge 21, the first error prevention plate 19 or the second positioning edge 22, the second error prevention plate 20 abut against the inner wall of the cavity 14, which is used for guiding during assembly, so as to improve the accuracy of the installation position of the drilling positioning cover 7 and the ink injection positioning cover 8, thereby improving the position accuracy of drilling and ink injection.

[0050] Further, the height of the second positioning edge 22 and the second error prevention plate 20 is greater than the length of the ink injection needle 25 after installation, so as to surround the ink injection needle 25 and form a safety fence to avoid being pricked.

[0051] The drilling positioning cover 7 is provided with a column 23. The positioning hole 9 is arranged at the center of the column 23 and penetrates through both ends of the column 23, so as to increase the depth of the positioning hole 9. A reinforcing sleeve 24 is installed in the column 23. The positioning hole 9 and the reinforcing sleeve 24 are tightly fitted. The reinforcing sleeve 24 is a metal sleeve, which is a copper sleeve in this embodiment. This avoids the damage of the positioning hole 9 by the drill bit during drilling, so as to avoid the inclination of the drill bit or even the damage of the ink cartridge.

[0052] The left and right sides of the base 6 are symmetrically provided with notches 44 for pinching the ink cartridge, so as to facilitate taking out the ink cartridge after refilling.

[0053] The center of the ink adding nozzle 10 is provided with a needle hole, and an ink injection needle 25 is installed in the needle hole. The ink injection needle 25 is used to guide the ink in the ink injection assembly 3 to the ink cartridge.

[0054] Further, the ink injection needle 25 is fixed with the needle hole by adhesive, which not only plays a fixed role, but also plays a sealing role.

[0055] Further, the ink adding nozzle 10 located at the needle hole is provided with an extension ring, the inner diameter of the extension ring is the same as the diameter of the needle hole, that is, the length of the needle hole is increased, thereby increasing the contact area with the ink injection needle 25, avoiding the swing of the ink injection needle 25, and causing the upper end of the ink injection needle 25 to be unable to cooperate with the ink outlet channel.

[0056] The first embodiment is a single ink supplementing structure: the cartridge body 11 is composed of a bottom box 26 and a cover 27, the air inlet 12 is arranged on the cover 27 and is sealed by a disposable sealing film 28, the ink outlet 13 is arranged at the bottom of the bottom box 26, the first sealing element 29 is arranged in the ink outlet 13, the first ink outlet channel 30 is arranged in the first sealing element 29, and the first self-sealing film 31 is arranged in the first ink outlet channel 30 and is pierced by the ink injection needle 25 during use.

[0057] When the ink cartridge is supplemented with ink, the ink outlet 13 is inserted into the ink adding nozzle 10, the first self-sealing film 31 is pierced by the ink injection needle 25, and then the disposable sealing film 28 is torn off, and the ink in the cartridge body 11 is supplemented into the ink cartridge through the first ink outlet channel 30.

[0058] The bottom of the bottom box 26 is provided with an inclined surface 32 inclined downward from the inner wall of the bottom box 26 to the ink outlet 13, and the ink outlet 13 is arranged at the lowest point of the bottom box 26.

[0059] The ink flows along the inclined surface 32 to the ink outlet 13, ensuring that the ink in the cartridge body 11 can all gather at the ink outlet 13 and finally be supplemented into the ink cartridge through the first ink outlet channel 30, avoiding the retention of a small amount of ink in the cartridge body 11 and causing waste of ink.

[0060] The ink outlet 13 is provided with a anti-extraction ring 45, and the sidewall of the first sealing element 29 is provided with an annular groove 46 corresponding to the anti-extraction ring 45, the anti-extraction ring 45 is embedded in the annular groove 46, and the first sealing element 29 is made of silica gel or other elastic materials, which can be directly pressed into the ink outlet 13 during installation.

[0061] The first sealing element 29 is provided with a plurality of arranged first sealing rings 47 on the lower side of the annular groove 46, and the first sealing rings 47 are tightly matched with the ink outlet 13. When the first sealing element 29 is installed, the first sealing rings 47 will be extruded by the inner wall of the ink outlet 13, causing the first sealing rings 47 to slightly deform, thereby improving the sealing effect.

[0062] The top surface of the cover 27 is provided with an annular protrusion 48 on the outer side of the air inlet 12. The disposable sealing film 28 is fixed on the annular protrusion 48 by hot pressing. When the disposable sealing film 28 is hot pressed, its shape will deform according to the shape of the annular protrusion 48, thereby increasing the contact area between the disposable sealing film 28 and the annular protrusion 48, thereby improving the adhesion effect. The air inlet 12 is located inside the annular protrusion 48. Since the entire annular protrusion 48 is in contact with the disposable sealing film 28, the air inlet 12 will naturally be sealed.

[0063] The top surface of the cover 27 is provided with several reinforcing protrusions 49 on the outer side of the annular protrusion 48. The disposable sealing film 28 is fixed to the reinforcing protrusions 49 by heat pressing. The reinforcing protrusions 49 are similar in design principle to the annular protrusions 48, mainly to increase the contact area with the disposable sealing film 28, thereby further improving the firmness of the bonding after heat pressing and preventing the disposable sealing film 28 from easily falling off, which would cause ink to evaporate or spill inside the box 11 and waste ink.

[0064] The second embodiment is a multi-refill structure: the cartridge 11 is provided with a main ink chamber 33 and a metering chamber 34 connected at the top. Above the main ink chamber 33 and metering chamber 34, the cartridge 11 is provided with an air valve chamber 35 connected through an air inlet 12. The air inlet 12 is located on one side of the air valve chamber 35. An air valve 36 for sealing the air inlet 12 is slidably installed in the air valve chamber 35. When the air valve 36 slides to separate from the air inlet 12, the air inlet 12 is opened. When the air valve 36 slides to the air inlet 12, the air inlet 12 is sealed. A second sealing element 37 is installed in the ink outlet 13. A second ink outlet channel 38 is provided in the second sealing element 37. A second self-sealing membrane 39 is provided in the second ink outlet channel 38, which is punctured by the ink injection needle 25 during use. A detachable sealing cap 40 is installed outside the ink outlet 13.

[0065] When not in use, both the main ink chamber 33 and the metering chamber 34 contain ink 65. When refilling the ink cartridge for the first time, insert the ink outlet 13 into the ink nozzle 10, slide the air valve 36 to open the air inlet 12, and the ink in the metering chamber 34 will be replenished into the ink cartridge through the ink outlet 13. When refilling ink in subsequent times, close the air inlet 12 and the ink outlet 13, tilt the entire cartridge, and allow the ink in the main ink chamber 33 to replenish the metering chamber 34. Then, the operation can be repeated to refill ink.

[0066] like Figure 16 As shown, the first ink replenishment is complete; the metering chamber 34 is empty, while the ink level in the main ink chamber 33 remains unchanged. Figure 17 As shown, the ink in the main ink chamber 33 is replenished to the metering chamber 34. At this time, the metering chamber 34 contains ink, and the amount of ink in the main ink chamber 33 decreases.

[0067] The outer side of the second seal 37 is provided with at least one second seal ring 61, when the second seal 37 is installed, the inner side of the ink outlet 13 extrudes the second seal ring 61 and makes it deformed, thereby improving the sealing performance of the ink outlet 13 and the second seal 37.

[0068] The inner side of the sealing cap 40 is provided with at least one third seal ring, when the sealing cap 40 is installed, the sealing cap 40 extrudes the third seal ring and makes it deformed, thereby improving the sealing performance of the ink outlet 13 and the sealing cap 40.

[0069] The sealing cap 40 is provided with a mounting seat 64 connected by a flexible band 63, and the mounting seat 64 is fixedly installed at the bottom of the cartridge body 11.

[0070] Further, the size of the mounting seat 64 is larger than the thickness of the flexible band 63, and the main shell 50 is provided with a sliding socket 62, and the flexible band 63 is inserted into the sliding socket 62, so as to limit the mounting seat 64 on the inner side of the main shell 50, and after the side cover 51 is installed, the installation of the sealing cap 40 can be realized.

[0071] Further, the sealing cap 40, the flexible band 63 and the mounting seat 64 are an integral structure, and are made of flexible materials such as silica gel.

[0072] The cartridge body 11 includes a main shell 50 and a side cover 51, the main shell 50 is provided with an ink storage cavity 52, the main ink chamber 33 and the dosing chamber 34 are arranged on the lower side of the ink storage cavity 52, the upper side of the ink storage cavity 52 is the part connected with the main ink chamber 33 and the dosing chamber 34, and a fixed sealing film 53 for sealing the ink storage cavity 52 is tightly attached to the side wall of the ink storage cavity 52 through a hot pressing process, so as to ensure the sealing effect and prevent ink leakage.

[0073] The rear wall of the main shell 50 is provided with a visible window 54 at the dosing chamber 34, and the visible window 54 is provided with a scale mark 55, which is used for observing the content of the ink in the dosing chamber 34, and the maximum amount of ink supplemented at one time is the maximum value shown by the scale mark 55, i.e. the maximum content of the dosing chamber 34.

[0074] For the ink cartridge with the same maximum content of the dosing chamber 34, the ink can be poured into the dosing chamber 34 to ensure that the ink in the dosing chamber 34 reaches the maximum value, and then the supplement is carried out, so as to avoid the situation that the content of the ink cartridge is 8ml, but due to incomplete pouring, the ink in the dosing chamber 34 is only 4ml, which leads to the fact that the ink in the ink cartridge cannot be fully supplemented, and the frequency of supplementing ink is increased.

[0075] When the ink cartridge with more than 8ml ink is refilled, the ink can be refilled in batches. For example, when the ink cartridge contains 10ml ink and the maximum content of the metering chamber 34 is 8ml, 8ml ink can be refilled first, and then 2ml ink can flow into the metering chamber 34 through the product, and then 2ml ink can be refilled.

[0076] The bottom of the air valve chamber 35 is provided with a low platform 41, a high platform 42, and a slope part 43 for connecting the low platform 41 and the high platform 42, and the air inlet 12 is arranged on the high platform 42.

[0077] When the air valve 36 slides from the low platform 41 to the high platform 42, the air valve 36 will be subjected to greater extrusion force due to the higher position of the high platform 42, thereby improving the sealing effect of the air valve 36 on the air inlet 12.

[0078] The outer side of the cartridge body 11 corresponds to the low platform 41 and the high platform 42, respectively, and is provided with an opening mark G and a closing mark F. The opening mark G and the closing mark F are distinguished by color, pattern, literal meaning, etc. For example, when color is used, green represents the opening mark G and red represents the closing mark F.

[0079] The air valve chamber 35 is provided with a sliding groove 56, and the air valve 36 is provided with a sliding block part 57 corresponding to the sliding groove 56. The sliding block part 57 is slidingly installed in the sliding groove 56, which serves to improve the stability of the sliding of the air valve 36.

[0080] Further, one side of the sliding groove 56 is on the main housing 50, and the other side is on the side cover 51. When the side cover 51 and the main housing 50 form a complete sliding groove 56, the sliding block part 57 of the air valve 36 is placed on the main housing 50 corresponding to the position of the sliding groove 56, and then the side cover 51 is installed.

[0081] The top of the air valve 36 is provided with a push rod 58, which extends out of the cartridge body 11 from the upper end of the air valve chamber 35. When the air valve 36 needs to be pushed, the push rod 58 can be pushed, which is convenient for the user to operate.

[0082] Further, the push rod 58 is provided with an indication mark H corresponding to the opening mark G and the closing mark F. When the indication mark H corresponds to the opening mark G or the closing mark F, it indicates that the air valve 36 has been slid into place.

[0083] The bottom of the air valve 36 is provided with a mounting column 59, and the mounting column 59 is provided with a sealing plug 60 for sealing the air inlet 12. The sealing plug 60 is a cylindrical structure with an upper opening. The side wall of the sealing plug 60 is used to fit on the mounting column 59, and the bottom of the sealing plug 60 is used to seal the air inlet 12.

[0084] Further, the sealing plug 60 is made of flexible material such as silica gel, when the air valve 36 slides from the low platform 41 to the high platform 42, the bottom of the sealing plug 60 is extruded, further deformed, thereby improving the sealing effect on the air inlet 12.
