[0028] Optionally, the middle portion of the second fluid infusion branch 3 adopts a circular coil structure, thereby saving the space occupied by the first fluid infusion branch.

[0029] A preferred solution of this embodiment is that one end of the main infusion pipe 1 is integrally connected to one end of the first infusion branch pipe 2 and one end of the second infusion branch pipe 3. This is equivalent to the main infusion pipe, the first infusion branch pipe and the second infusion branch pipe adopting a Y-shaped structure as a whole.
