The above arrangement makes the first flow guide piece 212 occupy different positions of the first interface 211 along the second direction Y, so as to achieve a better effect of preventing ink splashing.

[0042] In some embodiments, the vertical projection of the first flow guide piece 212 and the vertical projection of the first interface 211 at least partially overlap, so that the first flow guide piece 212 can effectively prevent the splashing of the ink.

[0043] Preferably, the first deflector 212 has a vertical projection that covers at least half of the vertical projection of the first interface 211, so that the first deflector 212 has a better anti-splashing effect on foreign matters.

[0044] In some embodiments, the first deflector 212 is obliquely arranged in the first interface 211, i.e., in the vertical direction, the vertical distance from the first deflector 212 to the first interface 211 gradually increases from the first side 2121 to the second side 2122, so as to meet the flow guiding effect on the ink.
