And the flow rate of the liquid can be regulated according to various air temperature environments so as to ensure that the liquid can flow through the capillary core before vaporization. And simultaneously, the filling strip can also play a role in thickening the outer wall and blocking heat, so that the heat is reduced to directly act on the liquid.
