The third side wall 521 is flush and smoothly transitions with the outer surface of the first side wall 213, and the fourth side wall 522 is flush and smoothly transitions with the outer surface of the second side wall 214.

[0108] Finally, the liquid storage cartridge assembly 30 is rotatably installed in the installation cavity 210 of the container shell assembly 20. Specifically, the protruding portion 312 of the liquid storage cartridge shell 31 is first obliquely inserted into the installation cavity 210, and then is rotated downward with the rotating hinge surface 3122 of the protruding portion 312 as the fulcrum, so that the liquid storage cartridge assembly 30 is finally installed in the installation cavity 210 of the container shell assembly 20.

[0109] Those skilled in the art can understand that the above assembly steps can be flexibly adjusted to realize automatic assembly, improve production efficiency, and reduce costs.
