Then, the second seating portion 111b may be formed in multiple stages inside the first seating portion 111a. In other words, the first seating portion 111a and the second seating portion 111b may be sequentially formed from the top of the cover housing 11' toward the inside of the discharge port 110'. In addition, since the second seating portion 111b is formed in multiple stages inside the first seating portion 111a, the second seating portion 111b may have a smaller cross-sectional area than the first seating portion 111a.

The grill 13 ′ may be supported on the first seating portion 111a. For example, the grill 13 ′ may be attached to and detached from the first seating portion 111a. In other words, the grill 13 ′ may be detachably attached to the first seating portion 111a without a separate coupling portion. Accordingly, the grill 13 ′ can be easily attached and detached by the user.

The blocking member 12 ′ may be supported on the second seating portion 111b. For example, the blocking member 12 ′ may include a mesh having a mesh structure and a connection portion formed on the outside of the mesh so as to be supported by the second seating portion 111b. The second seating portion 111b may include a coupling groove in which a connection portion of the blocking member 12 ′ and a position match. The blocking member 12 ′ may be screwed to the second seating portion 111b through a connection portion. In other words, the blocking member 12 ′ may be fixed to the second seating part 111b by screwing through the connection portion of the blocking member 12 ′ and the coupling groove. As a result, the blocking member 12 ′ can be easily separated and coupled from the second seating portion 111b only by fastening and releasing the screw fastening.
