Description

Technical Field

[0001] This utility model relates to the field of ink cartridge refilling technology, specifically to an ink cartridge refilling tool that can automatically stop refilling. Background Technology

[0002] Ink cartridges are the components in inkjet printers that store printing ink and ultimately complete the printing process. As ink cartridges are used, the ink inside is constantly consumed, so ink cartridges often need to be refilled, and refilling tools are used in the process.

[0003] Existing ink refilling tools are prone to ink overflow during the ink refilling process, causing great inconvenience to users; moreover, existing ink refilling tools are difficult to control and adjust the amount of ink added during the ink refilling process, making the ink refilling process rather cumbersome. Utility Model Content

[0004] The purpose of this invention is to provide an ink refill tool for ink cartridges that can automatically stop ink flow, thereby solving the problem mentioned in the background art that existing ink refill tools are prone to ink overflow during ink refilling and it is difficult to control and adjust the amount of ink refilled.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ink cartridge refilling tool with automatic stop function, comprising an ink refilling base assembly, the top of which is connected to an ink bottle assembly, the ink bottle assembly comprising an ink bottle bottom shell, an ink bottle top cover, an ink refill needle, and a stop component, wherein the ink bottle bottom shell and the ink bottle top cover are closed to form an ink storage cavity and a stop component, the stop component being used to automatically stop the ink flow during refilling.

[0006] Preferably, the ink filling base assembly includes an ink filling base and an ink filling cover plate. The ink filling cover plate is installed on the top of the ink filling base. The four edges of the bottom of the ink filling cover plate are integrally injection molded with limiting ribs, and the limiting ribs are interlocked with the ink filling base for limiting.

[0007] Preferably, the ink cartridge assembly contains an ink cartridge assembly, which includes an ink cartridge bottom shell and an ink cartridge top cover, and the ink cartridge bottom shell and the ink cartridge top cover fit together.

[0008] Preferably, the bottom of the ink bottle shell has an ink leakage hole that communicates with the ink storage chamber, and the ink filling needle is inserted into one side of the bottom of the ink bottle shell, and the ink filling needle communicates with the ink leakage hole.

[0009] Preferably, the stop assembly includes an air inlet chamber and a liquid seal needle. The air inlet chamber is located inside the bottom shell of the ink bottle, and the top of the air inlet chamber communicates with the ink storage chamber.

[0010] Preferably, the liquid seal needle is inserted into the other side of the bottom of the ink bottle bottom shell, and a vent hole is provided on one side of the bottom of the ink bottle bottom shell, and the vent hole communicates with the air inlet chamber and the vent hole communicates with the liquid seal needle.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: This ink cartridge refilling tool with automatic stop function, by setting a stop component, allows ink inside the ink storage chamber to enter the ink cartridge bottom shell through the ink leakage hole via the ink filling needle. Since the liquid sealing needle also enters the ink cartridge bottom shell, when the ink inside the bottom shell reaches the liquid sealing needle, it seals the needle. At this point, gas will not enter the air intake chamber through the liquid sealing needle and vent, thus stopping ink filling and achieving an automatic stop function during ink filling. This utility model achieves an automatic stop function during ink filling through the stop component, solving the problem of ink overflow during ink filling with existing refilling tools. Furthermore, the ink filling amount in the ink cartridge bottom shell can be adjusted by the insertion depth of the liquid sealing needle and the ink filling needle, making ink filling more convenient.

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. In addition, the terms "first", "second", "third", "upper", "lower", "left", "right", etc. are used for descriptive purposes only and should not be construed as indicating or implying relative importance. At the same time, in the description of the present utility model, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0019] This utility model provides a structure for an ink cartridge refill tool that can automatically stop ink flow, as shown in the following figure. Figure 1 as well as Figure 3 As shown, the device includes an ink refill assembly 1, which includes an ink refill base 1.1 and an ink refill cover 1.2. The ink refill cover 1.2 is installed on the top of the ink refill base 1.1. The four edges of the bottom of the ink refill cover 1.2 are integrally injection molded with limiting ribs 1.21, and the limiting ribs 1.21 are mutually inserted and limited with the ink refill base 1.1. An ink cartridge assembly 3 is placed inside the ink refill assembly 1. The ink cartridge assembly 3 includes an ink cartridge bottom shell 3.1 and an ink cartridge top cover 3.2, and the ink cartridge bottom shell 3.1 and the ink cartridge top cover 3.2 cover each other.

[0020] During implementation, the ink cartridge assembly 3 is placed inside the ink filling base 1.1. After placement, the ink filling cover 1.2 is closed to the ink filling base 1.1, and the closing is limited by the limiting rib 1.21.

[0021] Furthermore, such as Figure 2 as well as Figure 4 As shown, the top of the ink filling base assembly 1 is connected to the ink bottle assembly 2. The ink bottle assembly 2 includes an ink bottle bottom shell 2.1, an ink bottle front cover 2.2, an ink filling needle 2.3, and a stop assembly 2.4. The bottom of the ink bottle bottom shell 2.1 has an ink leakage hole 2.31, which communicates with the ink storage chamber 2.11. The ink filling needle 2.3 is inserted into one side of the bottom of the ink bottle bottom shell 2.1, and communicates with the ink leakage hole 2.31.

[0022] During implementation, the ink inside the ink storage chamber 2.11 will enter the ink cartridge bottom shell 3.1 through the ink leakage hole 2.31 and the ink filling needle 2.3. The liquid sealing needle 2.42 will also enter the ink cartridge bottom shell 3.1.

[0023] Furthermore, such as Figure 4 as well as Figure 5 As shown, after the ink bottle bottom shell 2.1 and the ink bottle top cover 2.2 are closed, an ink storage chamber 2.11 and a stop assembly 2.4 are formed. The stop assembly 2.4 is used to automatically stop the ink during ink filling. The stop assembly 2.4 includes an air inlet chamber 2.41 and a liquid seal needle 2.42. The air inlet chamber 2.41 is located inside the ink bottle bottom shell 2.1, and the top of the air inlet chamber 2.41 communicates with the ink storage chamber 2.11. The liquid seal needle 2.42 is inserted into the other side of the bottom of the ink bottle bottom shell 2.1. A vent hole 2.411 is opened on one side of the bottom of the ink bottle bottom shell 2.1, and the vent hole 2.411 communicates with the air inlet chamber 2.41 and the liquid seal needle 2.42.

[0024] During implementation, when the ink inside the ink cartridge bottom shell 3.1 is filled to the point of contacting the liquid seal needle 2.42, the liquid seal needle 2.42 will be sealed. At this time, gas will not enter the air intake chamber 2.41 through the liquid seal needle 2.42 and the vent hole 2.411, so the ink will not continue to be filled, thus realizing the automatic stop function when filling ink.

[0025] This invention achieves an automatic stop function during ink filling by setting a stop component 2.4, which solves the problem of ink overflow during ink filling of existing ink filling tools. Moreover, this invention can adjust the ink filling amount of the ink cartridge bottom shell 3.1 by adjusting the insertion depth of the liquid sealing needle 2.42 and ink filling needle 2.3, so ink filling is more convenient.

[0026] Working principle: When in use, first place the ink cartridge assembly 3 into the ink filling base 1.1. After placement, close the ink filling cover 1.2 onto the ink filling base 1.1. When closing, the limiting rib 1.21 provides a limiting position, which ensures that the ink filling needle 2.3 and the liquid sealing needle 2.42 are inserted into the ink cartridge assembly 3.

[0027] Next, the ink inside the ink storage chamber 2.11 will enter the ink cartridge bottom shell 3.1 through the ink leakage hole 2.31 and the ink filling needle 2.3. Since the liquid sealing needle 2.42 will also enter the ink cartridge bottom shell 3.1, when the ink inside the ink cartridge bottom shell 3.1 is filled to the point of contacting the liquid sealing needle 2.42, it will seal the liquid sealing needle 2.42. At this time, gas will not enter the air intake chamber 2.41 through the liquid sealing needle 2.42 and the vent hole 2.411, so the ink will not continue to be filled, thus realizing the automatic stop function during ink filling.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
