Description

Technical Field

[0001] The utility model relates to the technical field of inkjet printers, in particular to an ink supply device for an inkjet printer. Background Art

[0002] At present, the inkjet printers on the market mainly use the ink cartridge supply method, that is, the ink is stored in a disposable ink cartridge. The disadvantages of this method are: the capacity of the ink cartridge is limited, and A4 paper is generally exhausted after printing 400-500 sheets. If the printing volume is large, the ink cartridge needs to be replaced frequently, which causes a lot of inconvenience to users, especially some professional users. Since the ink cartridge is expensive, the price of the ink cartridge is one hundred to two hundred yuan or even higher, the printing cost is very high. There is also a method of using a syringe to fill the ink through the ink filling hole of the ink cartridge, but firstly, it is troublesome to use, and secondly, as the ink level gradually decreases, the pressure of the ink relative to the printer nozzle continues to decrease, so that the amount of ink sprayed changes, and the depth of the printed pattern or text is inconsistent, affecting the printing effect.

[0003] Patent CN212219663U proposes an automatic ink supply device for an inkjet printer. When the ink in the ink storage bottle is insufficient, new ink can be directly injected from the ink inlet tube, replacing the method of replacing the ink cartridge, effectively saving costs. At the same time, the method of injecting new ink from the ink inlet tube is simpler and more efficient than injecting ink using a syringe. Secondly, after the injection, the electronically controlled sealing valve is closed, and then the pressure pump is started to change the air pressure inside the ink storage bottle. The staff observes through the pressure gauge that when the air pressure inside the ink storage bottle reaches a suitable value, the pressure pump can be turned off. When the ink level is low, the pressure pump can also be started to pressurize the ink storage bottle to ensure the stability of the ink supply, thereby solving the problem that as the ink level of the traditional ink supply device gradually decreases, the pressure of the ink relative to the printer nozzle continues to decrease, the amount of ink sprayed changes, the depth of the printed pattern or text is inconsistent, and the printing effect is affected.

[0004] In the above scheme, the staff observes through the pressure gauge that when the air pressure inside the ink storage bottle reaches an appropriate value, the pressure pump can be turned off. When the ink level is low, the pressure pump can be started to pressurize the ink storage bottle to ensure the stability of the ink supply. However, this technical method requires manual real-time monitoring of pressure changes and then adjusting the pressure, which is inconvenient to operate. Utility Model Content
