Accordingly, the cartridge 30 can be easily inserted into the gear mounting hole 411.

Accordingly, the cartridge 30 can be easily removed from the gear mounting hole 411.

Accordingly, the cartridge 30 can be easily inserted into the insertion space 11 even if the first guide slot 316 and the inner peripheral projection 416 are not aligned with each other.

Accordingly, the cartridge 40 can be easily inserted and removed even if the first guide slot 316 and the second guide slot 326 are not aligned with each other.

As shown in FIG. 14-16, the cartridge 30 can be inserted into a gear mounting hole 411 formed in the cartridge gear 41. The cartridge 30 can be inserted in the direction of the rotation axis of the cartridge gear 41. The rotation axis direction of the cartridge gear 41 may be a vertical direction.

When the cartridge 30 is fully inserted into the insertion space 11, the inner peripheral projection 416 may be located at the upper end of the second guide slot 326.

Therefore, when the cartridge gear 41 is rotated, the second container 32 can be rotated because the inner peripheral projection 416 engages with the second guide slot 326. When the second container 32 is rotated, the position of the first container 31 can be maintained. When the second container 32 is rotated, the position of the container head 33 and the position of the mouthpiece 34 can be maintained.

The second guide slot 326 may include a portion that expands in a downward direction. The second guide slot 326 may have a maximum width at the lower end of the second container 32.

When the cartridge 300 is inserted into the insertion space 11, the heads 117 and 119 may hold the first container 39 in place. Even if the second container 32 is rotated, the first container 39 cannot be rotated because the heads 117 and 119 are inserted into the locking grooves 3917.

The first head 117 may be located in a position corresponding to a locking slot 3917 located at a relatively low level among several locking slots 3917 provided in the first container 39.

The width w3 of the first guide slot 3916 may be equal to the width w2 of the lower end of the second guide slot 326 in a portion adjacent the lower end of the second guide slot 326. The width w3 of the first guide slot 3916 may be equal to or greater than the width w1 of the top of the second guide slot 326. Width w3 of the first guide slot 316 may exceed the width w0 (see FIG. 13) of the inner peripheral projection 416.

Accordingly, even when the cartridge 300 is inserted into the gear mounting hole 411 in a state in which the first guide slot 3916 is not aligned with the second guide slot 326, the inner peripheral projection 416 smoothly moves along the side surfaces of the first guide slot 3916 and the second guide slot 326, thereby thereby aligning the first guide slot 3916 with the second guide slot 326.

Therefore, since the opening 3259 of the first disc communicates with the opening 323 of the lower chamber in precise alignment, a decrease in the efficiency of the aerosol flow can be prevented.
