Description

Technical Field

[0001] This utility model relates to the field of ink cartridge technology, and in particular to a high-capacity printer ink cartridge. Background Technology

[0002] An ink cartridge is a component in a printer used to store and supply printing ink. It typically contains liquid ink or powder (used in laser printers), which is ejected onto paper through the printhead to form text or images. The design and type of ink cartridges vary depending on the printer brand and model; the most common types are inkjet and laser printers. The selection and replacement of ink cartridges have a certain impact on print quality and printer lifespan, therefore choosing the right ink cartridge is crucial.

[0003] In existing technology, most printer ink cartridges have only one main ink tank. In some special circumstances, such as when the ink inside the ink tank is used up and there is no external ink reserve, it will affect the normal use of the printer and may also affect the normal operation of some important tasks. Therefore, we urgently need a high-capacity printer ink cartridge. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: a high-capacity printer ink cartridge, comprising a main ink tank, a secondary ink tank fixedly installed on the outside of the main ink tank, transparent windows provided on both outer surfaces of the main ink tank from top to bottom, a water level sensor embedded in the bottom of the main ink tank, an alarm fixedly installed on the top of the main ink tank, a control chip fixedly connected to one outer wall of the main ink tank, a print head penetrating the bottom of the main ink tank, and an ink inlet mechanism provided between the main ink tank and the secondary ink tank.

[0005] As an improvement to the above technical solution, a main ink tank inlet is provided on one side of the top of the main ink tank, and a main ink tank ink plug is sealed and inserted inside the main ink tank inlet. An integrally formed secondary ink tank inlet is provided on the upper side of one side of the secondary ink tank, and a secondary ink tank ink plug is sealed and inserted inside the secondary ink tank inlet.

[0006] As an improvement to the above technical solution, the print head and the control chip are electrically connected, and the water level sensor and the alarm are electrically connected.

[0007] As an improvement to the above technical solution, the ink feeding mechanism includes square movable slots opened on the outer surfaces of both sides of the main ink tank. The side surface of the main ink tank is also provided with an ink injection port, and the ink injection port is located inside the square movable slots. The interior of the main ink tank is connected to the interior of the auxiliary ink tank through the ink injection port.

[0008] As an improvement to the above technical solution, the ink feeding mechanism further includes a square sealing plug that is slidably installed inside the square movable slot. The volume of the square sealing plug is larger than the slot of the ink filling port. The main ink tank also has multiple through holes inside. The through holes inside the main ink tank are located at the upper end of the square movable slot and are connected to the square movable slot. A spring is installed inside the through hole. One end of the spring is fixedly connected to the upper end of the square sealing plug, and the other end of the spring is fixedly connected to the inner wall of the through hole. A pull block is fixedly installed at the bottom of the square sealing plug.

[0009] As an improvement to the above technical solution, the inner wall of the square movable slot is provided with sealing grooves on both sides, and the square sealing plug is provided with sealing sliders on both sides. The square sealing plug and the sealing sliders are integrally formed, and the sealing sliders are slidably installed inside the sealing grooves. A sealing film is glued to the inner surface of the square movable slot.

[0010] The beneficial effects of this utility model are:

[0011] 1. By fixing the secondary ink tank to the outside of the main ink tank and setting an ink inlet mechanism between the main ink tank and the secondary ink tank, the ink inlet mechanism can open the secondary ink tank when the ink in the main ink tank is used up, allowing the spare ink in the secondary ink tank to be injected into the main ink tank. This ensures that the printer can still be used in special circumstances, such as when there is no external ink, thus avoiding affecting the work and increasing the overall ink capacity of the device to a certain extent.

[0012] 2. By opening transparent windows on both sides of the main ink tank, the ink usage in the main ink tank can be clearly observed through the transparent windows, so as to add ink and avoid affecting the normal operation of the printer. At the same time, by setting water level sensors and printheads, an alarm can be set when the ink is almost used up to remind people to add ink. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a high-capacity printer ink cartridge, including a main ink tank 1, a secondary ink tank 2 fixedly installed on the outside of the main ink tank 1, transparent windows 3 provided on both sides of the outer surface of the main ink tank 1 from top to bottom, a water level sensor 4 embedded in the bottom of the main ink tank 1, an alarm 5 fixedly installed on the top of the main ink tank 1, a control chip 8 fixedly connected to one side of the outer wall of the main ink tank 1, a print head 6 penetratingly connected to the bottom of the main ink tank 1, and an ink inlet mechanism provided between the main ink tank 1 and the secondary ink tank 2.

[0020] In this implementation scheme, a secondary ink tank 2 is fixedly installed on the outside of the main ink tank 1, and an ink inlet mechanism is set between the main ink tank 1 and the secondary ink tank 2. The function of the ink inlet mechanism is to open the secondary ink tank 2 when the ink in the main ink tank 1 is used up, so that the spare ink in the secondary ink tank 2 can be injected into the main ink tank 1. This prevents the printer from still being used in some special situations, such as when there is no external ink, thus avoiding affecting the work process and increasing the overall ink capacity of the device to a certain extent. Transparent windows 3 are opened on both sides of the main ink tank 1. By observing the transparent windows 3, the ink usage in the main ink tank 1 can be clearly seen, so that ink can be added and the normal operation of the printer can be avoided. At the same time, by setting up a water level sensor 4 and a print head 6, an alarm can be set when the ink is almost used up to remind people to add ink.

[0021] Specifically, the main ink tank 1 has a main ink tank inlet 101 on one side of its top, and a main ink tank plug 102 is sealed and inserted inside the main ink tank inlet 101. The secondary ink tank 2 has an integrally formed secondary ink tank inlet 201 on one side of its upper end, and a secondary ink tank plug 202 is sealed and inserted inside the secondary ink tank inlet 201.

[0022] Specifically, the print head 6 and the control chip 8 are electrically connected, and the water level sensor 4 and the alarm 5 are electrically connected.

[0023] Specifically, the ink feeding mechanism includes square movable slots 7 formed on the outer surfaces of both sides of the main ink tank 1. An ink inlet 103 is also formed on the side surface of the main ink tank 1, and the ink inlet 103 is located inside the square movable slots 7. The interior of the main ink tank 1 is connected to the interior of the auxiliary ink tank 2 through the ink inlet 103. The ink feeding mechanism also includes a square sealing plug 71 slidably installed inside the square movable slots 7. The volume of the square sealing plug 71 is larger than the slot of the ink inlet 103. Multiple through holes are also formed inside the main ink tank 1, and these through holes are located at the upper end of the square movable slots 7 and are connected to the square... The movable slots 7 are connected, and a spring 74 is installed inside the through hole. One end of the spring 74 is fixedly connected to the upper end of the square sealing plug 71, and the other end of the spring 74 is fixedly connected to the inner wall of the through hole. A pull block 75 is fixedly installed at the bottom of the square sealing plug 71. Sealing grooves 73 are opened on both sides of the inner wall of the square movable slot 7. Sealing sliders 72 are provided on both sides of the square sealing plug 71. The square sealing plug 71 and the sealing sliders 72 are integrally formed. The sealing sliders 72 are slidably installed inside the sealing grooves 73. A sealing film 711 is glued to the inner surface of the square movable slot 7.

[0024] In this embodiment, by setting an ink inlet mechanism between the main ink tank 1 and the secondary ink tank 2, in some special cases, such as when there is no external ink, the backup ink in the secondary ink tank 2 can be activated. When the backup ink in the secondary ink tank 2 is activated, by pulling the pull block 75 set at the bottom of the square sealing plug 71, the square sealing plug 71 can be moved downward. At this time, the spring 74 is stretched, and the sealing slider 72 slides inside the sealing groove 73. When the ink inlet 103 covered by the square sealing plug 71 is exposed, the backup ink in the secondary ink tank 2 can enter the main ink tank 1 for the printer to continue to work normally. With the cooperation of the sealing slider 72 and the sealing groove 73, the square sealing plug 71 can be prevented from shifting during the movement.

[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
