Even when the cover 310 applies external force to the end of the stick 400 in the second direction, the stick 400 may be guide so as to be precisely inserted into the insertion space 214.
Furthermore, even when stick 400 pushes the cover 310, thus causing the cover 310 to be disposed in the insertion space 214, the cover 310 may be received in the cover groove 215, whereby the stick 400 may be brought into close contact with the wall defining the insertion space 214. Accordingly, when a user inhales air through the stick 400, it is possible to prevent air from unnecessarily flowing between the wall of the insertion space 214 and the stick 400.
In addition, it is possible to restrict movement of the stick 400 into the second chamber C2.
Furthermore, because the cover 310 is pivoted when the stick 400 is separated from the insertion space 214, it is possible to automatically close the insertion space 214. In addition, it is possible to protect the interior of the insertion space 214 from external contaminants.
