In the above prior art, when the user does not use the flavor suction pipe, the mouthpiece can be covered with a cap and the mouthpiece covered to cover the mouthpiece in a sanitary manner. However, the user has to store the cap removed from the mouthpiece separately during use of the flavor suction pipe, and the removed cap is easily lost, and thus lacks user convenience.

Also, if the cap is lost during use of the flavor suction pipe, the user is forced to store the mouthpiece suction port with the mouthpiece's mouthpiece exposed after use of the flavor suction pipe. Can not be maintained.
The objective of this invention is providing the suction device which can improve a user's convenience significantly, maintaining a mouthpiece hygienically.

The above object is achieved by the suction device of the present invention, which has a casing having an open base, a filling material that is accommodated in the casing and volatilizes the suction target component, and sucks the suction target component. A mouthpiece portion having a mouthpiece end that can be made, a cap portion that communicates with the mouthpiece portion and has an opening end on the opposite side of the mouthpiece portion, and is separably coupled to the base end of the casing between the mouthpiece end and the opening end. A hollow mouthpiece having a coupling portion, and the coupling portion can be coupled to the proximal end in both a direction in which the suction port portion is on the filling material side and a direction in which the cap portion is on the filling material side.

Preferably, the casing has an accommodation space in which the mouthpiece can be accommodated when the mouthpiece coupling portion is coupled to the base end of the casing in a direction in which the mouthpiece is the filling material side, and the filling material is filled. And has a cartridge in which gas flow is allowed.
Preferably, the coupling portion includes a suction side coupling portion formed on the suction portion side of the cap portion, and an opening side coupling portion formed on the opening end side of the cap portion.

Preferably, the filling material comprises a tobacco material.
Preferably, the mouthpiece has a channel opening / closing means for opening and closing a gas channel flowing through the mouthpiece.
