In use, the proximal end 110 is the end closer to a user for ease of inhalation; the distal end 120 is the end further away from the user. In some embodiments as shown, the first body 100 can be flat in shape. The length dimension of the first body 100 is greater than the width dimension, and the width dimension is greater than the thickness dimension. Figures 1 to 12

[0075] According to Figures 1 to 12 As shown, the first body 100 comprises:

In some embodiments, the main housing 10 and / or the mouthpiece 20 can be formed of a metal or an alloy such as stainless steel, aluminum, etc.; other suitable materials include various plastics, metal-plated plastics, ceramics, etc.

[0077] According to Figures 1 to 12 As shown, the main housing 10 is generally configured in the shape of a frame or a box extending along the longitudinal direction. The main housing 10 has a longitudinally extending receiving cavity 11 formed or defined therein; the second body 200 can be received and retained in the receiving cavity 11. The receiving cavity 11 is open from the front side 150 to the rear side 160. In embodiments, the receiving cavity 11 is open at the front side 150 and the rear side 160.

[0078] According to Figures 1 to 6 As shown, the first body 100 further comprises:
