The connecting joint 123 may have a function of releasably coupling the vaporizing unit 14 to the fixed unit 13. A screw structure is formed in the lower part of the connection joint 123 and a screw structure is formed in the upper joint 131 formed in the upper part of the fixed unit 13 so that the vaporizing unit 14 is fixed to the fixed unit 13. [ (13). ≪ / RTI > Various separable structures are possible and the invention is not limited to the embodiments shown.

An air inflow gap 123a may be formed at the lower end of the connecting joint 123. [ The air inlet gap 123a is provided for allowing the internal air introduced into the fixed unit 13 to be introduced into the vaporization unit 12, which will be described below.

The fixed unit 13 is coupled to the lower portion of the storage container 11 and is located inside the storage container 11. [
