An inkjet printer performs printing by ejecting ink from a recording head onto a recording medium (for example, printing paper).

FIG. 1 schematically shows an example of a conventional inkjet printer. Fig. 1 is a perspective view of an inkjet printer, wherein the inkjet printer 1 includes a printer body 12 and an ink containing unit 11, and the ink containing unit 11 is fixedly installed on a certain side of the printer body 12 (for example, the right side shown in Fig. 1 on the side). For ease of description, based on the user's position when using the inkjet printer 1 , the user's direction is defined as the front, the opposite direction is the rear, and the user's left and right hand directions are respectively defined as the left and right directions.

FIG. 2 schematically shows an example of a conventional ink containing unit. The ink containing unit 11 generally includes an ink containing part 14 containing ink and a frame part 16 covering the ink containing part 14 outside the ink containing part 14, and the top of the frame part 16 has an injection port 15 for injecting ink and a cap for closing the ink containing part 14. The injection port plug 17 of the injection port 15. When the user performs an ink filling operation, the ink bottle 13 is turned upside down so that ink is injected from above the ink containing portion 14 through the inlet. Because the bottle cap body 13b of the ink bottle 13 is non-detachably connected with the bottle cap body 13a through the connecting portion 13c, the result is that when the ink bottle 13 is filled with ink, the bottle cap body 13b is usually placed on the bottle cap One side of the main body 13a is pressed against the adjacent injection port plug 17 to receive a reaction force, so that the ink bottle 13 cannot be smoothly inserted into the injection port 15, and thus it is difficult to fill ink.

Therefore, it is necessary to propose an ink containing unit and an inkjet printer to at least partly solve the above problems existing in the prior art.
