[Prior Art] In general, an inkjet printer has been widely used by consumers because it has the advantages of being easy to operate and can be printed on a variety of inkjet media. It has become an essential product in personal electronics. However, after using the inkjet printer for a period of time, it will be replaced by the ink of the ink E. The common replacement method is to discard the old ink and install the new ink to provide the ink. This not only causes waste of the ink cartridge, but also invisibly increases the user's overhead due to the high price of the ink cartridge. In order to save printing costs and avoid waste of resources, repeated use of the same ink cartridge continuous ink supply system was born. The conventional inkjet printing system is described in US Patent Publication No. 2001/0006395, which discloses an inkjet printing system for replacing ink supply, and the inkjet printing system 100 is as shown in the first figure. And comprising a row of printing ends 101 connected to the replaceable ink supply port 1〇3 through the first-class conduit 1〇2, the printing end 101 receiving the ink conveyed from the fluid conduit 102, flowing from the fluid inlet 104 The printing end ιοί, and under the control of the system control electronic component 105, the ink is ejected from the ejector 1〇6 onto the inkjet medium, however, in order to maintain the printing end 101 with an internal negative pressure, at the printing end 1〇 1 An adjuster 107 is internally provided to store air and adjust the negative pressure in the printing end 1〇7 6 200924988.

According to the above description, the continuous ink supply system for the ink cartridge provided with the air bag and the exhaust structure provided in the present invention is provided with an elastic air bag 162, pressure plates 163, 164 and elasticity in the ink storage tank 161. The internal pressure adjustment design of the elastic air bag of the components 165 and 166, and the discharge ink cartridge 10 are provided with an exhaust structure 10A and with the air suction of the air suction device to perform the pumping action of the internal pressure balance for printing the ink of the continuous ink supply system.匣1〇 has a good internal pressure balance adjustment. When the use of the ink supply cartridge 20 is continuously replaced, the total amount of air source of the inkjet printing system may be greater than 4.5 cc, but due to the ink storage tank 161. The air bag 162, the pressure plates 163 and 164 and the elastic element inner pressure adjusting mechanism formed by the elastic elements 165 and 166 are provided, so that the inner column pressure of the column 13 200924988 is adjusted, and the pressure adjustment fails. The column forgets the problem of ink leakage. When the total amount of internal air is too high, the exhaust structure 10A set by the ink cartridge 10 can be used and the pumping action is performed with the pump 3〇 for continuous supply. Ink system of ink system 10 The internal pressure can maintain the balance adjustment. In the specific implementation, the implementation time of the Guopu 30 can be controlled according to the replacement of the ink supply or the inkjet printing quantity; in addition, the continuous ink supply system of the case is provided for the first time. The ink cartridge 20 needs to be inked into the ink cartridge 匣1〇, and the ink tube 2〇1 is in a vacuum state. At this time, it is difficult to use the siphon principle to draw ink, so it is also possible to use the ink cartridge 10 The exhaust structure 10A is provided with the pumping device 30 for pumping first, and the pumping action is performed to enable the ink in the ink supply cartridge 20 to be smoothly introduced into the ink tube 201, so that the ink tube 201 becomes filled with ink. The state is beneficial to the benefit of the subsequent ink guiding of the entire ink supply system, and is highly compensated and progressive. In summary, the continuous ink supply system for inkjet and venting structures in this case consists of a printing ink cartridge, an ink supply cartridge, and an air suction device. The ink tube is provided with an ink cover to print the ink cartridge, and the ink cartridge includes an ink cartridge body having an air bag, a cover body, a valve sheet layer and an upper cover, wherein the air bag is used for adjusting the inside of the ink cartridge body Back pressure, and by the action of the air suction device, the air is exhausted through the ink discharge channel of the ink jet, so that the pressure of the communication space between the upper cover and the valve layer changes, and then the valve layer is opened. The valve plate structure is used for gas transportation. Because the exhaust structure of the present invention can effectively exclude the gas inside the ink cartridge, and maintain the airtightness inside the ink cartridge, the ink leakage is not generated, and It can extend the life of the printed ink cartridge and improve the printing quality. Therefore, the continuous ink supply system for the ink bag and the inkjet structure of the 200924988 exhaust structure is of great industrial value, and the application is made according to law.
