[0029] like Figure 1-Figure 7 As shown, an ink cartridge refilling device includes an ink bottle 100, an ink outlet tube 300 is installed on the upper end of the ink bottle 100, and an ink adding mechanism for adding ink to the ink cartridge, and the ink adding mechanism is located above the ink bottle 100.

[0030] In this embodiment, the ink adding mechanism includes a threaded sleeve 201 arranged at the upper end of the ink outlet tube 300 , an ink adding component for adding ink to the ink cartridge, and a breakout component. The threaded sleeve 201 is threadedly connected to the ink outlet tube 300 .

[0031] The rupture component includes a sliding sleeve 203 which is slidably installed on the upper end of the threaded sleeve 201, and a sealed cavity 216 is enclosed between the sliding sleeve 203 and the threaded sleeve 201. A pointed cone 206 is fixed to the lower end of the sliding sleeve 203, and a ring blade 207 is fixed to the lower end of the pointed cone 206. A compression spring is connected between the sliding sleeve 203 and the threaded sleeve 201, a sealing paper 202 is arranged on the upper end of the ink outlet tube 300, and a pressing pad 215 is fixed on the side wall of the sliding sleeve 203.

[0032] The ink filling assembly includes a fixed sleeve 208 arranged at the upper end of the sliding sleeve 203, and an ink filling groove 217 is opened in the middle position of the fixed sleeve 208. The ink filling groove 217 is in a cone shape with the small end facing upward, and a limiting sleeve 210 is fixed to the bottom end of the ink filling groove 217. A rubber plug 209 is slidably installed in the limiting sleeve 210. The rubber plug 209 is in a cone shape with the small end facing upward, and a return spring is connected between the rubber plug 209 and the limiting sleeve 210. A connecting rod 218 is slidably installed at the lower end of the fixed sleeve 208. The connecting rod 218 is in the shape of the letter E with the opening facing upward, and the middle part is fixedly connected to the rubber plug 209. The connecting rod 218 is slidably connected to the limiting sleeve 210, and a downward pressure spring is connected between the connecting rod 218 and the fixed sleeve 208. A sealing structure is arranged between the sliding sleeve 203 and the threaded sleeve 201, and the sealing structure is used to seal unused ink to prevent leakage.

[0033] The sealing structure includes a sealing cover 204 rotatably mounted on the upper end of the sliding sleeve 203, a sealing block 205 is fixed to the lower end of the sealing cover 204, the sealing block 205 is consistent with the upper end diameter of the ink adding groove 217, and a plurality of top screws 211 are arranged on the threaded sleeve 201 near the upper end of the sealing cavity 216. The top screws 211 are threadedly connected to the threaded sleeve 201, and a rotating structure is arranged above the top screws 211. The rotating structure is used to synchronously rotate the plurality of top screws 211 downward.

[0034] The rotating structure includes a gear 212 fixed to the upper end of the top screw 211, a toothed ring 213 is arranged on the outer side of the top screw 211, the toothed ring 213 is rotatably connected to the threaded sleeve 201, the gear 212 is meshed with the toothed ring 213, the teeth on the inner side of the toothed ring 213 are higher than the teeth on the outer side of the gear 212, and a plurality of handles 214 are fixed on the outer side of the toothed ring 213. Before using the ink bottle 100, the threaded sleeve 201 is rotatably connected to the ink outlet tube 300 at the upper end of the ink bottle 100, and then the pressing pad 214 is pressed downward. 15 drives the sliding sleeve 203 to move downward, drives the pointed cone 206 to move downward, and makes the annular blade 207 at the lower end of the pointed cone 206 puncture the sealing paper 202 at the upper end of the ink outlet tube 300. After puncturing, the compressed spring drives the pointed cone 206 to reset upward, and then the ink filling component is used to add the ink in the ink bottle 100 into the ink cartridge, and there is no need to tear off the sealing paper 202, thereby reducing the cumbersomeness of using the ink bottle 100, making it more convenient to use and speeding up the time of filling ink.

[0035] Working principle: first, rotate and tighten the threaded sleeve 201 onto the ink outlet tube 300, then press the pressing pad 215 downward to drive the sliding sleeve 203 to move downward, drive the pointed cone 206 to move downward, so that the annular blade 207 at the lower end of the pointed cone 206 punctures the sealing paper 202 at the upper end of the ink outlet tube 300. After puncturing, release the pressing pad 215, and use the compression spring to drive the pointed cone 206 to reset upward, so that the ink can flow out of the ink bottle 100.

[0036] Then open the sealing cover 204 upwards, insert the fixed sleeve 208 in the sliding sleeve 203 into the ink inlet of the ink cartridge, and the side wall of the ink inlet presses the connecting rod 218 at the lower end of the fixed sleeve 208. The ink inlet just wraps the upper end of the fixed sleeve 208, and the downward movement of the connecting rod 218 drives the rubber plug 209 to move downward. At this time, the rubber plug 209 is separated from the fit with the inner wall of the ink filling groove 217, and a certain gap is formed between the two, so that the ink flows out from the gap and flows into the ink cartridge for ink filling.

[0037] When the ink in the ink bottle 100 is not used up and needs to be stored after the ink is added, the sliding sleeve 203 is pulled out, and the rubber plug 209 in the ink adding groove 217 continues to move to the upper end of the ink adding groove 217 under the action of the reset spring to reset, and the upper end of the ink adding groove 217 is blocked again, and then the sealing cover 204 is covered, and the sealing block 205 at the lower end of the sealing cover 204 seals the upper end of the ink adding groove 217, and then the handle 214 is turned to drive the toothed ring 213 to rotate, and the toothed ring 213 and the top screw 213 are rotated. The gear 212 at the upper end is meshed, driving the plurality of top screws 211 to rotate, so that the top screws 211 move downward while rotating, extend into the sealing cavity 216, and push the sliding sleeve 203 downward, driving the sliding sleeve 203 to move downward, thereby driving the pointed cone 206 to move downward, and then the pointed cone 206 blocks the punctured opening of the sealing paper 202, further preventing the ink inside the ink bottle 100 from leaking, thereby improving the sealing performance of the ink bottle 100 and reducing the deterioration of the ink.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
