The outer wall of the pipe body 240 and the casing 250 The inner wall is mainly used to define the portion of the first fluid channel 12 in the body 200. The heater 400 is sleeved on the tube 240. Specifically, in this embodiment, the inner layer 410 is sleeved on the tube 240, and the tube 240 The cooperation with the inner layer 410 can limit the runout of the negative ion member 500 in the radial direction of the inner layer 410.

In addition, the design of the first notch 417 and the second notch 419 can also reduce the axial dimension of the overall structure composed of the heater 400 and the negative ion member 500, so that the structure of the body 200 is more compact.

In other embodiments, the second connecting section 514 may be threaded through the second gap 419, and the third connecting segment 516 is threaded through the first gap 417.
