The ink bag in the ink supply device is detachably connected with the ink box, the ink bag can be replaced, after a customer uses up the ink in the ink bag, only the ink bag needs to be replaced, and the ink bag does not have an ink box orifice chip, so that the cost is low, the customer can purchase the ink bag only at a low price, the lower printing cost is realized, and the service life of the nozzle chip is fully utilized.
Illustratively, as shown in fig. 1, 2, and 10, the ink cartridge 110 includes a cartridge body 112 and an ink inlet assembly 113. As shown in fig. 4 and 5, the ink bag main body 122 includes an ink reservoir portion 122a and a support portion 122b connected to the ink reservoir portion 122 a. In the present embodiment, the ink storage portion 122a is a flexible bag-shaped structure, for example, an ink bag made of a soft plastic material, which has a simple structure and a low cost, and other shapes and flexible materials may be used. The supporting portion 122b is made of a hard material, such as hard plastic, and may support the ink storage portion, or may be made of other materials.
As shown in fig. 6 and 7, the support portion 122b is provided with an ink outlet passage 122c, and the ink outlet passage 122c communicates with the ink inlet assembly 113 and the ink reservoir 122a, respectively. As shown in fig. 2 and 7, the ink in the ink reservoir 122a may sequentially enter the ink cartridge 110 through the ink outlet passage 122c and the ink inlet assembly 113 to provide ink to the ink cartridge 110.
Illustratively, as shown in fig. 4 and 5, the support portion 122b is located at the top of the ink reservoir 122a on the side toward the ink inlet assembly 113.
