Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 An ink supply assembly for an inkjet printer includes a mounting structure for installation protection, and an ink storage structure for piston-type ink storage disposed within the mounting structure. An alarm structure for magnetic clamping triggering an alarm and pulling unlocking is disposed in front of the ink storage structure.

[0026] In this embodiment: the installation structure includes an installation compartment 101, a compartment cover 102 is provided on the top of the installation compartment 101, a hook 104 is provided at the front end of the lower part of the compartment cover 102, and two spring hinges 103 are symmetrically arranged on both sides between the compartment cover 102 and the installation compartment 101. When the hook 104 is engaged, the compartment cover 102 closes the installation compartment 101. When the hook 104 is unlocked, the spring hinges 103 automatically open the compartment cover 102.

[0027] In this embodiment: the ink storage structure includes an ink storage box 201, an ink outlet pipe 202 is provided at the bottom of the ink storage box 201, an ink filling pipe 203 is provided at the rear end of the ink storage box 201, a sealing cover 204 is provided at the top of the ink filling pipe 203, a piston plate 205 is slidably installed inside the ink storage box 201, and a permanent magnet 206 is provided on the front side of the upper surface of the piston plate 205. When the sealing cover 204 is opened, ink is added to the ink storage box 201 through the ink filling pipe 203. When ink is supplied, the ink in the ink storage box 201 flows out through the ink outlet pipe 202, which reduces the pressure in the ink storage box 201 and pulls the piston plate 205 to drive the permanent magnet 206 to move downward.

[0028] In this embodiment, the alarm structure includes a fixed plate 301, a magnetic suction plate 302 behind the fixed plate 301, a pressure plate 304 in front of the fixed plate 301, two connecting rods 303 symmetrically arranged on both sides between the pressure plate 304 and the magnetic suction plate 302, a trigger button 305 behind the pressure plate 304, a buzzer 306 above the trigger button 305, a hanging rod 307 hinged to the top of the pressure plate 304, a rotating seat 308 located near the upper middle of the hanging rod 307, a return spring 309 located on the front side of the top of the hanging rod 307, an electrical connection between the buzzer 306 and the trigger button 305, a rotatable connection between the hanging rod 307 and the rotating seat 308, and a rotatable connection between the rotating seat 308 and the mounting chamber 101. When the ink is about to run out, the piston plate 205 will drive the permanent magnet 206 to move downward to the height of the magnetic suction plate 302, and attract the magnetic suction plate 302 to move backward. The magnetic suction plate 302 will drive the pressure plate 304 to move backward through the connecting rod 303. Under the support of the fixed plate 301, the pressure plate 304 will press the trigger button 305, triggering the buzzer 306 to sound an alarm. At the same time, the pressure plate 304 will drive the bottom of the hanging rod 307 to rotate backward under the support of the rotating seat 308, so that the top of the hanging rod 307 will move forward to compress the return spring 309 and disengage from the hook 104. At this time, the hook 104 will be released from the restriction of the hanging rod 307, thereby unlocking the compartment cover 102. The compartment cover 102 will automatically pop open under the action of the spring hinge 103.

[0029] Working principle: During ink supply, the ink in the ink reservoir 201 flows out through the ink outlet tube 202, reducing the pressure inside the ink reservoir 201 and pulling the piston plate 205 downward. When the ink is about to run out, the piston plate 205 will drive the permanent magnet 206 downward to the height of the magnetic suction plate 302, attracting the magnetic suction plate 302 to move backward. This causes the magnetic suction plate 302 to drive the pressure plate 304 backward via the connecting rod 303. Under the support of the fixed plate 301, the pressure plate 304 is pressed, triggering the buzzer 306 to sound an alarm. At the same time, the pressure plate 304 drives the bottom of the hanging rod 307 to rotate backward under the support of the rotating seat 308, thereby causing the top of the hanging rod 307 to move forward and compress the return spring 309, disengaging it from the hook 104. At this time, the hook 104 is released from the restriction of the hanging rod 307, thereby unlocking the compartment cover 102. The compartment cover 102 will automatically pop open under the action of the spring hinge 103, revealing the ink storage box 201 inside the installation compartment 101, making it convenient to open the sealing cover 204 and add ink to the ink storage box 201 through the ink filling tube 203.
