Description

Technical Field

[0001] This utility model relates to the field of ink cartridge technology, specifically to an ink cartridge with ink volume measurement and indication functions. Background Technology

[0002] An ink cartridge is a container that holds printing ink. It's a key component in inkjet printers, used to store printing ink and ultimately complete the print job. Ink cartridges play a vital role in inkjet printers, especially in lower-end models where their price can sometimes rival that of the printer itself. The ink cartridge contains liquid ink. Ink cartridges can print in both color and black ink separately. For example:

[0003] Chinese Patent Publication No. CN218054534U discloses an ink cartridge with a remaining ink level display function. The cartridge includes an ink cartridge with a mounting groove on one side of its outer wall. A scale plate is installed on the inner wall of the mounting groove. A display base is installed on the inner wall of one side of the cartridge, and a prompting plate is slidably connected inside the display base. A connecting line is installed on the top of the prompting plate, and a float is installed at the other end of the connecting line away from the prompting plate. The float's weight is slightly greater than the prompting plate. A guide seat is installed on the outer wall of the display base, and the connecting line passes through the interior of the guide seat. In this invention, the float floats on the ink and is connected to the prompting plate via the connecting line. When the float moves downward, the connecting line moves downward, causing the prompting plate to move upward. The position of the prompting plate can be observed through the scale plate, allowing for timely monitoring of the ink level and prompt refilling. A filter screen filters the ink, preventing impurities in the ink from clogging the printhead.

[0004] Based on existing solutions and actual production and processing, current ink cartridges still have some problems, such as:

[0005] 1. When measuring the amount of ink, the amount of ink inside the ink cartridge is measured through the float, connecting wire, and indicator panel. During the measurement of the amount of ink inside the ink cartridge, the connecting wire rubs against the display base, which can easily cause the connecting wire to break.

[0006] 2. When indicating the ink level inside the ink cartridge, it is often necessary for personnel to disassemble and check the internal condition of the ink cartridge, which is time-consuming and labor-intensive. Therefore, this utility model provides an ink cartridge with ink level measurement and indication functions to solve the above-mentioned problems. Utility Model Content

[0007] The purpose of this invention is to provide an ink cartridge with ink volume measurement and indication functions, so as to solve the problems mentioned in the background art of poor measurement effect of ink volume inside the ink cartridge and inconvenient indication of ink volume inside the ink cartridge.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an ink cartridge with ink volume measurement and indication functions, comprising an ink cartridge body, an inkjet head fixedly disposed on the lower middle side of the body, an ink filling tube fixedly installed on the upper left side of the ink cartridge body, and a tube cap movably connected to the upper side of the ink filling tube to serve as a blocking function.

[0021] 2. When the ink inside the ink cartridge decreases, the ink causes the float to slide downward inside the ink cartridge, which in turn causes the float to slide the steel cable on the outside of the roller, which in turn causes the roller to rotate inside the mounting bracket. This causes the steel cable to slide the moving block upward inside the sealing plate, allowing the transparent plate on the right side of the ink cartridge to view the height of the moving block and easily measure the ink level.

[0022] 3. The float slides inside the ink cartridge body, causing the float to move upward on the inside of the sealing plate via a steel cable. This causes the moving block to slide upward on the inside of the sealing plate, moving the push rod to the lower side of the connecting block. The push rod then slides in the middle of the connecting block, causing the push rod and the sealing plate to contact the contact sensor. The processor receives the signal from the contact sensor and displays a prompt on the printer screen for easy notification. Attached Figure Description

Detailed Implementation

[0031] 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.

[0032] Please see Figure 1-7 This utility model provides a technical solution: an ink cartridge with ink volume measurement and indication functions, comprising: an ink cartridge body 1, an inkjet head 2, an ink filling tube 3, a tube cover 4, a mounting panel 5, a fixing plate 6, a mounting plate 7, a movable block 8, a sealing plate 9, a transparent plate 10, a processor 11, a roller 12, a steel cable 13, a connecting block 14, a contact sensor 15, a float 16, a moving block 17, a push rod 18, a fixing rod 19, and a mounting bracket 20. In operation, the specific details are as follows... Figure 1 , Figure 4 and Figure 5As shown, a mounting plate 6 is fixedly installed on the lower right side of the mounting panel 5, and a mounting plate 7 is fixedly connected to the outer right side of the mounting panel 5. A movable block 8 is movably connected to the inner right side of the mounting plate 7. The ink cartridge body 1 is manually placed on the right side of the mounting panel 5, so that the ink cartridge body 1 is manually positioned on the upper side of the mounting plate 6, thereby moving and mounting the ink cartridge body 1 inside the mounting plate 7. Then, the movable block 8 is manually pushed, causing the movable block 8 to rotate inside the right side of the mounting plate 7. This rotation of the movable block 8 causes the ink cartridge body 1 to... The movable block 8 is attached to the outer side of the right end of the ink cartridge body 1, thereby limiting the position of the movable block 8 on the ink cartridge body 1. Then, the fixing rod 19 is manually tightened, so that the fixing rod 19 is threadedly connected to the inner side of the middle of the movable block 8. Under the action of the thread between the movable block 8 and the fixing rod 19, the fixing rod 19 rotates to the left. Then, under the action of the fixing rod 19 rotating to the left, the fixing rod 19 is threadedly connected to the middle of the right end of the ink cartridge body 1, which facilitates the limitation of the movable block 8 and facilitates the installation and placement of the ink cartridge body 1.

[0033] Specific examples Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, an ink filling tube 3 is fixedly installed on the upper left side of the ink cartridge body 1. A tube cap 4 is movably connected to the upper end of the ink filling tube 3. An inkjet head 2 is fixedly installed on the lower middle side of the ink cartridge body 1. Manually pulling the tube cap 4 upwards causes it to separate from the ink filling tube 3 under the pulling force. The ink container is placed on the upper side of the ink filling tube 3 and tilted, allowing ink to flow into the interior of the ink cartridge body 1 through the ink filling tube 3. The ink inside the ink cartridge body 1 is then ejected through the inkjet head 2. After the ink inside the ink cartridge body 1 is ejected through the inkjet head 2, the amount of ink inside the ink cartridge body 1 decreases. This causes the float 16 floating on the ink surface to move downwards as the ink decreases, thus... The downward movement of block 16 causes the float 16 to move the steel rope 13, which then moves above the roller 12. This movement of the steel rope 13 causes the roller 12 to rotate inside the mounting bracket 20. Furthermore, the movement of the steel rope 13 causes the moving block 17 to slide upwards inside the sealing plate 9. A scale line is provided on the transparent plate 10 located on the right side of the ink cartridge body 1, with the value decreasing towards the top. This allows the height of the moving block 17 to be observed through the transparent plate 10. The scale line on the upper side of the transparent plate 10 allows for the measurement of the ink level inside the ink cartridge body 1, facilitating ink volume measurement.

[0034] Specific examples Figure 1 , Figure 2 , Figure 3 and Figure 7As shown, a contact sensor 15 is fixedly installed inside the upper part of the sealing plate 9 via a connecting block 14. When the ink inside the ink cartridge body 1 decreases, the float 16, which moves using the buoyancy of the ink, moves the steel cable 13. Under the action of the steel cable 13, the moving block 17 slides upward inside the sealing plate 9. The upward movement of the moving block 17 then causes the push rod 18 to slide upward inside the sealing plate 9, moving the push rod 18 to the lower side of the connecting block 14. Under the action of the upward movement of the moving block 17, the push rod 18 slides to the inner side of the connecting block 14. The telescopic sliding action between the push rod 18 and the connecting block 14 causes the sealing plate 9 and the push rod 18 to contact and activate the contact sensor 15. The activation signal of the contact sensor 15 is transmitted through the wiring harness to the processor 11 installed on the upper right side of the ink cartridge body 1. The processor 11 processes the activation signal of the contact sensor 15 and transmits it to the printing press display screen for display, providing a convenient prompt.
