Technical Field
[0001] This utility model relates to the field of printer technology, specifically a printer with waste ink recycling function. Background Technology
[0002] A printer is one of the output devices of a computer, used to print the results of computer processing onto relevant media. However, the ink extracted during printer cleaning is usually a mixture of black, blue, red, and yellow inks. The resulting liquid is black and can be used for everyday non-photo-quality printing work where color accuracy is not critical.
[0003] Currently, existing printers generate a lot of waste ink during cleaning. After extraction, this waste ink often causes environmental pollution, which causes great inconvenience to users. Utility Model Content
[0004] The purpose of this invention is to provide a printer with a waste ink recycling function to solve the problem mentioned in the background art that existing printers generate a lot of waste ink during cleaning, and this waste ink usually causes environmental pollution after extraction.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a printer with waste ink recovery function, including an ink cartridge assembly, a printer printhead, a printhead cleaning assembly, a filter assembly, and a waste ink recovery unit. The ink cartridge assembly and the printer printhead are interconnected via an ink supply pipeline. The printhead cleaning assembly is used to scrape off residual ink from the surface of the printer printhead. The filter assembly is connected to the printhead cleaning assembly via an ink pipeline and is used to filter impurities in the ink of the printhead cleaning assembly. The filter assembly is connected to the waste ink recovery unit via an ink pipeline, and a waste ink pump is installed on the waste ink pipeline connecting the waste ink recovery unit and the ink cartridge assembly.
[0006] During printing, the printer printhead completes printing with ink supplied by the ink cartridge assembly. When the printhead needs to be cleaned, the printhead cleaning assembly automatically cleans the printer printhead. The waste ink that is cleaned passes through the printhead cleaning assembly and enters the filter assembly, and is finally pumped into the ink cartridge assembly by the waste ink pump for reuse.
[0007] Preferably, the ink cartridge assembly includes, but is not limited to, a yellow ink cartridge, a red ink cartridge, a blue ink cartridge, a photo black ink cartridge, and a black ink cartridge, which are installed side by side from left to right inside the ink cartridge assembly.
[0008] Preferably, the yellow ink cartridge, red ink cartridge, blue ink cartridge, photo black ink cartridge, and black ink cartridge are all interconnected with the printer printhead via ink supply lines.
[0009] Preferably, the yellow ink cartridge supplies yellow ink for all printing; the red ink cartridge supplies red ink for all printing; the blue ink cartridge supplies blue ink for all printing; the photo black ink cartridge supplies black ink for photo printing; and the black ink cartridge supplies black ink for everyday non-photo printing.
[0010] Preferably, the printer printhead also includes an ink pump, which uses negative pressure to draw dried waste ink from the nozzles of the printer printhead, filters impurities from the ink through a filter assembly, and then sends the ink to a waste ink recycling unit.
[0011] Preferably, the waste ink collector is equipped with a liquid level detector, which is used to detect the liquid level after waste ink is recovered in the waste ink collector, and after being triggered, controls the waste ink pump to transport the waste ink in the waste ink collector to the black ink box through the waste ink pipeline.
[0012] Compared with existing technologies, the beneficial effects of this invention are as follows: When printing, the printer head prints through the ink supply line with ink supplied by the ink cartridge assembly. When the print head needs cleaning, the print head cleaning assembly automatically cleans the print head. The cleaning ink is a mixture of black, blue, red, and yellow ink. The cleaned waste ink is filtered through the ink line by the print head cleaning assembly and then enters the filter assembly. When the liquid level reaches the trigger level of the liquid level detector, the liquid level detector controls the waste ink pump to pump the waste ink into the black ink cartridge in the ink cartridge assembly for reuse. This invention can rationally recycle and reuse the waste ink collected during daily print head cleaning. Simultaneously, this invention reduces waste ink pollution to the environment, significantly reducing the generation of printer waste ink. Furthermore, it greatly reduces the probability of the printer's waste ink collector being full and requiring replacement, eliminating the need for a separate maintenance box that collects waste ink and requires frequent replacement, which does not actually help with printing.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.
[0017] The structure of the printer with waste ink recycling function provided by this utility model is as follows: Figure 1 As shown, the device includes an ink cartridge assembly 1, a printer printhead 2, a printhead cleaning assembly 3, a filter assembly 4, and a waste ink collector 5. The ink cartridge assembly 1 and the printer printhead 2 are interconnected via an ink supply line. The printhead cleaning assembly 3 is used to scrape off residual ink from the surface of the printer printhead 2. The filter assembly 4 is connected to the printhead cleaning assembly 3 via an ink line and is used to filter impurities in the ink in the printhead cleaning assembly 3. The filter assembly 4 is connected to the waste ink collector 5 via an ink line, and a waste ink pump 6 is installed on the waste ink line connecting the waste ink collector 5 and the ink cartridge assembly 1.
[0018] During printing, the printhead 2 completes printing with ink supplied by the ink cartridge assembly 1. When the printhead needs to be cleaned, the printhead cleaning assembly 3 automatically cleans the printhead 2. The waste ink that is cleaned passes through the printhead cleaning assembly 3 and enters the filter assembly 4. Finally, it is pumped into the ink cartridge assembly 1 by the waste ink pump 6 for reuse.
[0019] Furthermore, such as Figure 2 As shown, the ink cartridge assembly 1 includes, but is not limited to, a yellow ink cartridge 11, a red ink cartridge 12, a blue ink cartridge 13, a photo black ink cartridge 14, and a black ink cartridge 15. The yellow ink cartridge 11, red ink cartridge 12, blue ink cartridge 13, photo black ink cartridge 14, and black ink cartridge 15 are installed side by side from left to right inside the ink cartridge assembly 1. The yellow ink cartridge 11, red ink cartridge 12, blue ink cartridge 13, photo black ink cartridge 14, and black ink cartridge 15 are all interconnected with the printer printhead 2 through ink supply lines.
[0020] In practice, the yellow ink cartridge 11 is used to supply yellow ink for all printing; the red ink cartridge 12 is used to supply red ink for all printing; the blue ink cartridge 13 is used to supply blue ink for all printing; the photo black ink cartridge 14 is used to supply black ink for photo printing; and the black ink cartridge 15 is used to supply black ink for everyday non-photo printing.
[0021] Furthermore, such as Figure 1 As shown, the printer nozzle 2 also includes an ink pump, which uses negative pressure to draw dried waste ink from the nozzles of the printer nozzle 2 through the filter assembly 4 to filter impurities in the ink before it enters the waste ink collector 5. The waste ink collector 5 is equipped with a liquid level detector 51, which is used to detect the liquid level of the waste ink after waste ink collection in the waste ink collector 5, and controls the waste ink pump 6 to transport the waste ink in the waste ink collector 5 to the black ink cartridge 15 through the waste ink pipeline after triggering.
[0022] Working Principle: During use, the ink extracted by the printer during cleaning is a mixture of black, blue, red, and yellow inks. The resulting liquid is black. This invention allows the mixed liquid to be processed and used for everyday non-photo-quality printing where color accuracy is not critical. Specifically, during printing, the printer printhead 2 prints with ink supplied by the ink cartridge assembly 1 through the ink supply pipeline. When printhead cleaning is required, the printhead cleaning assembly 3 automatically cleans the printhead 2. The cleaning ink is a mixture of black, blue, red, and yellow inks. The waste ink mixture is filtered through the ink pipeline by the printhead cleaning assembly 3 and then enters the filter assembly 4. When the liquid level detector 51 reaches the trigger level, the liquid level detector 51 controls the waste ink pump 6 to pump the waste ink into the black ink cartridge 15 in the ink cartridge assembly 1 for reuse.
