Description

Technical Field

[0001] The utility model relates to the technical field of printer ink cartridges, in particular to an ink cartridge with an ink cartridge head frame. Background Art

[0002] Ink cartridges are important components in printers. They are mainly used to store ink or toner and supply it to the print head. The quality and performance of ink cartridges directly affect the print quality and the service life of the printer. Therefore, it is very important to choose the right ink cartridges.

[0003] The Chinese patent with announcement number CN211730689U discloses an ink cartridge with an ink cartridge holder. By opening the cover on the injection port, the ink injection device is embedded in the injection groove of the injection port shell and engaged with the lower pressure plate. Excess gas is discharged through the exhaust ports on both sides, and then a certain pressure is applied to the ink injection device to push the lower pressure plate to move vertically downward on the sliding groove, so that the sealing block on it contacts the ink circulation pipe on the baffle, thereby pushing the sealing block open to connect the ink circulation pipe, and injecting ink into the ink cartridge. When the device is in use, when the ink injection device is embedded, the propelled gas can be discharged to avoid external air from mixing into the ink cartridge, so that the ink cartridge will be out of ink when printing. The ink injection port on the box body of the above-mentioned device is convex, so when manually filling, ink side leakage may occur, and injecting ink into the box body by injection is too slow. Utility Model Content

[0004] The utility model aims to provide an ink cartridge with an ink cartridge head frame, which is convenient for disassembling and replacing the ink cartridge, thereby solving the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions.

[0006] An ink cartridge with an ink cartridge head frame comprises an ink cartridge and a cartridge frame.

[0007] An inner cavity is arranged in the box frame, and a mounting opening is arranged on an end surface of the box frame close to the ink box, and the mounting opening is communicated with the inner cavity;

[0008] An ink inlet is installed in the installation port, both ends of the ink inlet are open, a bottom plate is installed at the bottom end of the ink inlet, and a guide rod is fixedly installed at the top end of the bottom plate along its axis;

[0009] A print head is mounted at the bottom end of the cartridge frame;

[0010] An ink outlet is installed on one end surface of the ink cartridge close to the cartridge frame and aligned with the mounting port, and the outer wall diameter of the ink outlet is slightly smaller than the inner wall diameter of the mounting port;

[0011] The opening of the ink outlet is glued and sealed with a sealing sticker, which is made of polyurethane material;

[0012] Side enclosures are symmetrically installed on both sides of the box frame along its width direction, and penetrating card slots are provided on the end surfaces of the two side enclosures that are close to each other;

[0013] Card blocks matching the card slots are installed at both ends of the box frame along its width direction;

[0014] The ink cartridge is placed on the cartridge rack, and the ink cartridge is limited between the card slots surrounded on both sides by two card blocks.

[0015] It can be seen that the ink outlet and the ink inlet are respectively installed on the opposite surfaces of the ink cartridge and the cartridge rack, and a sealing sticker is glued and sealed at the opening of the ink outlet. The upper and lower ends of the ink inlet are both open, and the lower end of the ink inlet is installed with a bottom plate, and the top of the bottom plate is installed with a guide rod along its axis. In this way, after the ink cartridge is placed on the cartridge rack, the ink outlet on the ink cartridge is inserted into the ink inlet after passing through the installation port, and the guide rod in the ink inlet can pierce the sealing sticker on the ink outlet, so that the ink in the ink cartridge falls into the inner cavity, so that the print head at the bottom of the cartridge rack can perform inkjet printing. In this way, the ink cartridge can be directly placed on the cartridge rack each time it is used, and when the ink in the ink cartridge is used up, it can be directly removed and replaced with a new one for easy disassembly and installation. The ink cartridge is limited between the card slots on the two sides by two card blocks, so that the ink cartridge can be horizontally limited on the cartridge rack and will not fall off from the cartridge rack during printing.

[0016] Furthermore, a sliding hole and a limiting hole are provided on the side periphery at one end in the width direction of the ink cartridge, and the sliding hole and the limiting hole are symmetrically arranged on both sides of the top end of the side periphery away from the axis thereof;

[0017] The depth of the sliding hole is greater than the depth of the limiting hole; a first limiting ring is installed at the end of the sliding hole;

[0018] A slide rod is slidably installed in the slide hole, a second limiting ring is installed at the bottom end of the slide rod, and the second limiting ring and the first limiting ring limit each other;

[0019] A limiting block is slidably installed in the limiting hole, and the limiting block is connected to the top end of the sliding rod through a limiting rod.

[0020] By setting the depth of the sliding hole to be greater than the depth of the limiting hole, the limiting rod can be pulled upward to make the limiting block disengage from the limiting hole and then rotated to the other side to take out the ink cartridge. Conversely, the limiting block is inserted into the limiting hole to vertically limit the ink cartridge.

[0021] Furthermore, a ring array of penetrating filter slots is provided on the bottom plate, and filter screens are installed in the filter slots.

[0022] By arranging that the filter slots are all equipped with filter nets, when the ink in the ink cartridge leaks into the cartridge frame, the impurities therein will be filtered out, and at the same time, the debris generated after the sealing sticker is punctured can also be filtered out.

[0023] Furthermore, a cutter head is installed at one end of the guide rod away from the bottom plate, and the cutter head is in a conical shape that is narrow at the top and wide at the bottom.

[0024] By setting the cutter head to be a cone shape that is narrow at the top and wide at the bottom, it is easy to puncture the sealing sticker and at the same time increase the puncture area of ​​the sealing sticker, so that the ink in the ink box flows into the inner cavity faster.

[0025] Furthermore, a liquid level sensor is installed at the bottom end of the bottom plate, and the liquid level sensor does not contact the inner bottom wall of the inner cavity.

[0026] A liquid level sensor is installed at the bottom end of the bottom plate, which can detect the amount of ink in the inner cavity. The liquid level sensor does not contact the bottom wall of the inner cavity. When the amount of ink in the inner cavity is lower than the liquid level sensor, the ink cartridge can be replaced, so that the inner cavity will not be short of ink during printing.
