The phase change material may also exhibit a liquid state after the phase change is completed, and the content of the liquid may be adjusted so that the liquid is adsorbed to the inner surface of the cooling segment 202 body structure in the form of a thin film. Some components of a phase change material may undergo a phase change at one temperature, and other components may undergo a phase change at another temperature. By controlling the component ratios of these different phase change materials, the temperature of the mist can be controlled within a small temperature range. This small temperature range is controllable, in other words customizable. In this way, the user experience can be improved.

Of course, the phase change material may be a single component.
