The oil reservoir 701 is formed between the outer casing 71 and the inner casing 72. Specifically, reservoir chamber 701 is an annular groove disposed around inner shell 72. A smoke outlet channel 702 is formed inside the inner shell 72. In the present embodiment, the top ends of the inner shell 72 and the outer shell 71 are a unitary structure, i.e., the inner shell 72 and the outer shell 71 are made as a single piece.

The preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the details of the above embodiments, and the technical concept of the present invention can be within the scope of the present invention, and can be modified to various simple variants, and these simple variants all belong to the protection scope of the present invention. The various features described in the foregoing detailed description may be combined in any suitable manner without departing from the scope of the invention. In order to avoid unnecessary repetition, the present invention does not separately describe various possible combinations.
