Description

Technical Field

[0001] The utility model relates to the technical field of ink cartridge residue detection, in particular to a device for detecting the residue of an ink cartridge for an inkjet printer. Background Art

[0002] As a widely used small printing machine, printers have been widely used in various fields by people. Most of the existing printer machines use the conversion of electrical energy into mechanical energy for printing. Inkjet printers are favored and used by office workers or small-scale printing personnel because of their low price and simple operation. Among them, the ink cartridge mainly refers to the component in an inkjet printer that stores printing ink and finally completes printing. The ink cartridge plays a very important role in the whole inkjet printer.

[0003] After long-term printing, the ink will continuously decrease during use. In the existing printing machines, the ink cartridges are generally dark in color throughout, making it inconvenient to see the internal ink volume. During printing, the operator cannot judge the remaining ink in the ink cartridge, so the ink in the ink cartridge cannot be replenished in time. Some printing machines are equipped with detection mechanisms, but when the oil level is detected to be insufficient, the machine will stop immediately. When printing urgent documents, it may be impossible to print all of them, thus affecting work efficiency. Based on this, this solution provides a device for detecting the residue of an ink cartridge for an inkjet printer to solve the above problems. Summary of the Utility Model

[0004] To solve the above technical problems, a device for detecting the residue of an ink cartridge for an inkjet printer is provided, and this technical solution solves the problems proposed in the above background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

A weight sensor is arranged between the ink cartridge and the base. The right side of the bottom inner wall of the ink cartridge is fixedly connected with a high platform. A pair of sliding rods are slidably installed on the left side of the top plate of the ink cartridge. The lower ends of the two sliding rods are fixedly connected with the upper end of a connecting plate. The lower end of the connecting plate is fixedly connected with a floating plate. The upper ends of the two sliding rods are fixedly connected with the lower end of a pressing plate. An inductor is arranged on the lower side of the pressing plate. The inductor is fixedly installed on the left side of the top of the ink cartridge. Both the pressing plate and the inductor are arranged inside a transparent cover. The transparent cover is fixedly installed on the left side of the top of the ink cartridge.

[0007] Preferably, a refilling tube is arranged at the left end of the ink cartridge, and a sealing cap is threadedly connected to the outer end of the refilling tube.

[0011] Compared with the prior art, the present utility model provides a device for detecting the remaining material of an ink cartridge for an inkjet printer, having the following beneficial effects:

[0012] 1. In the present utility model, there are two detections for the remaining material. When the ink in the ink cartridge is used, the horizontal height of the ink in the ink cartridge gradually decreases as it is used. Thus, as the horizontal height of the ink decreases, the floating block is driven to descend, and then the height of the connecting plate decreases. The descending of the connecting plate drives the sliding rod, and the sliding rod drives the pressing plate until the lower end of the pressing plate contacts the sensor. At this time, the warning light lights up, and together with the sound generator, it gives a reminder signal to the user, reminding the operator to replenish in time. At this time, there is still a small amount of ink at the ink outlet pipe inside the ink cartridge, so that the current printing work will not stop, avoiding the situation where not all printing can be completed. As it continues to be used, when the weight sensor detects that the ink is completely used up, at this time, the printing machine stops working, and an alarm signal is emitted through the alarm light and the sound generator.

[0017] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0018] Referring to Figure 1-2 As shown, an ink cartridge residue detection device for an inkjet printer includes an ink cartridge 1 and a base 2. The lower end of the ink cartridge 1 is arranged inside the base 2. A weight sensor 10 is arranged between the ink cartridge 1 and the base 2. A high platform 3 is fixedly connected to the right side of the inner wall of the bottom of the ink cartridge 1. A pair of sliding rods 4 are slidably installed on the left side of the top plate of the ink cartridge 1. The lower ends of the two sliding rods 4 are fixedly connected to the upper end of a connecting plate 5. A floating plate 6 is fixedly connected to the lower end of the connecting plate 5. The upper ends of the two sliding rods 4 are fixedly connected to the lower end of a pressing plate 7. An inductor 8 is arranged on the lower side of the pressing plate 7. The inductor 8 is fixedly installed on the left side of the top of the ink cartridge 1. Both the pressing plate 7 and the inductor 8 are arranged inside a transparent cover 9. The transparent cover 9 is fixedly installed on the left side of the top of the ink cartridge 1. When the ink in the ink cartridge 1 is being used, the horizontal height of the ink in the ink cartridge 1 gradually decreases with use. Thus, the decrease in the horizontal height of the ink drives the floating block 6 to descend, and then the height of the connecting plate 5 decreases. The decrease of the connecting plate 5 drives the sliding rods 4, and the sliding rods 4 drive the pressing plate 7 until the lower end of the pressing plate 7 contacts the inductor 8. At this time, the warning light 16 lights up, and a reminder signal is sent to the user in cooperation with the sound generator 18, reminding the operator to replenish in time. When the weight sensor 10 detects that the ink is completely used up, at this time the printer stops working, and an alarm signal is sent through the alarm light 17 in cooperation with the sound generator 18. Among them, both the inductor 8 and the weight sensor 10 can adopt sensors that can achieve this function in the prior art, without limitation.

[0019] Specifically, in this embodiment, an ink filling tube 11 is arranged at the left end of the ink cartridge 1. A sealing cap 12 is threadedly connected to the outer end of the ink filling tube 11. When the ink is insufficient, by rotating the sealing cap 12, ink is added to the inside of the ink cartridge through the ink filling tube 11.

[0020] Specifically, in this embodiment, an ink outlet tube 13 is arranged at the lower left end of the ink cartridge 1. A filter screen 14 is arranged at the top end of the ink outlet tube 13. The filter screen 14 is fixedly installed at the bottom of the ink cartridge 1. The filter screen 14 can filter the ink material to prevent sediment lumps from forming due to the long storage time of the ink material, and the filter screen 14 can intercept the sediment

[0021] Specifically, in this embodiment, the height of the high platform 3 is higher than the top end of the ink outlet tube 13. The height of the high platform 3 is level with the lowest point of the floating plate 6. The left end of the high platform 3 is inclined. The high platform 3 and the side plate of the ink cartridge 1 cooperate with each other to form a groove. When the floating plate 6 reaches the lowest point, at this time the lower end of the pressing plate 7 contacts the inductor 8. At this time, the warning light 16 lights up, and a reminder signal is sent to the user in cooperation with the sound generator 18, reminding the operator to replenish in time. At this time, there is still a small amount of ink at the ink outlet tube 13 inside the ink cartridge 1, so that the current printing work will not stop, avoiding the situation where not all prints can be completed.

[0022] Specifically, in this embodiment, a mounting plate 15 is fixedly connected to the left end of the ink cartridge 1. A warning light 16 and an alarm light 17 are arranged on the surface of the mounting plate 15, and sound generators 18 are arranged on both sides of the warning light 16 and the alarm light 17. When the warning light 16 is on, it means that the ink in the current printer is insufficient and needs to be replenished. When the alarm light 17 is on, it means that there is no ink in the current printer and it cannot work. It is convenient for workers to judge through the warning light 16 and the alarm light 17.

[0023] The working principle of the present utility model is as follows: When the ink in the ink cartridge 1 is used, the horizontal height of the ink in the ink cartridge 1 gradually decreases with the use. Thus, the floating block 6 is driven to descend due to the decrease in the horizontal height of the ink, and then the height of the connecting plate 5 decreases. The descending of the connecting plate 5 drives the sliding rod 4, and the sliding rod 4 drives the pressing plate 7 until the lower end of the pressing plate 7 contacts the inductor 8. At this time, the warning light 16 is on, and together with the sound generator 18, a reminder signal is sent to the user to remind the operator to replenish in time. At this time, there is still a small amount of ink in the ink cartridge 1 at the ink outlet pipe 13, so that the current printing work will not stop, avoiding the situation that not all prints can be completed. When the weight sensor 10 detects that the ink is completely used up, the printer stops working at this time, and an alarm signal is sent through the alarm light 17 and the sound generator 18.

[0024] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
