The cartridge body 110 has a pair of

vent holes

111 and 112 for introducing and discharging air on one side thereof, and a space portion that is a flow path through which the introduced air flows is formed. In more detail, the pair of

vent holes

111 and 112 are arranged side by side on the upper portion of the cartridge body 110, and the flow path formed by the inner space of the cartridge body 110 is discharged from the introduced air. It is formed to have at least one bending section. In this case, the cartridge body 110 is combined with the lower body 160 to form a single body.

The cartridge body 110 is formed in a substantially rectangular parallelepiped shape, and a pair of

vent holes

111 and 112 are formed in parallel directions. Stepped between the pair of

vent holes

111 and 112 has a bending section. That is, the pair of

vent holes

111 and 112 forming the air inlet and the outlet of the cartridge body 110 are disposed on one side and the other side of the cartridge body 110, respectively, and the vent hole 111 is provided. Air passages connecting the 112 are formed to have at least one bending section.

Therefore, the flow air in the limited space stays in the cartridge body 110 for as long as possible, thereby increasing the effect of the fragrance divergence. In this case, the cartridge body 110 is not necessarily limited to the rectangular parallelepiped shape, and may be implemented in other shapes.

The cartridge body 110 is installed by arranging a plurality of carriers for holding and releasing incense along the air flow path. The plurality of carriers are formed to have different fragrance supporting structures so that the periods of retaining and releasing fragrance are different.

The first carrier 150 has a substantially rectangular parallelepiped shape and is provided in the cartridge main body 110 and positioned at the bottom of the cartridge main body 110. The first carrier 150 has a honeycomb structure and has a gel with concentrated aroma. The first carrier 150 is made to retain the fragrance for a relatively long time. This honeycomb structure and concentrated gel retention can contribute to retaining the first carrier 150 for a long time.

In addition, the first carrier 150 is formed in a pair and spaced apart from each other. As a result, the pair of first carriers 150 are positioned below the pair of

vent holes

air vents

111 and 112 becomes a structure passing through the second carrier 140 via the first carrier 150, and thus has a second fragrance retention property. As the flowing air passes through the carrier 140 and the first carrier 150 having a long-term fragrance retention property, the aromatic carboxylic acid is made stable and continuously.

The third carrier 130 is formed in a pellet form, and has a hollow shape and contains a gel having concentrated aroma. The third carrier 130 has a smaller size than the first carrier 150, and a plurality of third carriers 130 are filled in the upper space of the second carrier 150. The third carrier 130 is made to retain a relatively medium flavor. That is, the third carrier 130 retains the fragrance of the gel form in a relatively long period of time compared to the liquid flavor, and has a smaller unit shape and size than the first carrier 150 of the honeycomb structure. It is made of a phosphorus form to have a shorter period of time compared to the first carrier 150.

As a result, the air introduced into one of the

air vents

111 and 112 necessarily passes through the third carrier 130 and the second carrier 140 to pass through the first carrier 150. Flowing air passes through the third carrier 130 having the medium-term fragrance retention property, the second carrier 140 having the short-term fragrance retention property, and the first carrier 150 having the long-term fragrance retention property. Hyangbalsan is more stable and consistent.

In addition, it is preferable that the third carrier 130 is additionally filled in the space between the pair of first carriers 150. As a result, the third carrier 130 fills the other space that is not occupied by the first carrier 150 and the second carrier 140 in the inner space of the cartridge body 110 to provide more continuous and stable fragrance emission. Make it possible. In addition, a coating layer may be formed on at least one surface of the third carrier 130. The coating layer 131 maintains the fragrance component contained in the third carrier 130 to last longer.

In summary, the carriers are arranged adjacent to the first carrier 150 disposed on the air flow path of the cartridge body 110 and the pair of

air vents

111 and 112 forming air inlets and outlets. And a carrier 130 and a second carrier 140 disposed between the first carrier 150 and the third carrier 130.
