The second outer shell 12 is integrated with the inner shell 13. On the one hand, the structure and process can be simplified. On the other hand, the heat generated by the heating element 20 can be quickly transferred to the second outer shell 12 through the inner shell 13, which can prevent local overheating. And the heating effect is better.

Of course, in other embodiments, the second outer shell 12 and the inner shell 13 can also be separated, but there may be a problem of thermal resistance, which reduces the heat transfer between the second outer shell 12 and the inner shell 13 .
