DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(9) Hereinafter, referring to the attached drawings, a technical configuration of an aroma-diffusing cartridge for a vehicle according to the present invention will be described in detail as follows.

(10) FIG. 2 is a perspective view of an aroma-diffusing cartridge for a vehicle according to a preferred embodiment of the present invention, FIG. 3 is an exploded perspective view of the aroma-diffusing cartridge, FIG. 4 is a cross sectional view showing the inside of the aroma-diffusing cartridge, and FIG. 5 is a perspective view showing a first carrier and a third carrier of the aroma-diffusing cartridge.

(11) As shown in FIGS. 2 to 5, the aroma-diffusing cartridge for a vehicle according to the preferred embodiment of the present invention includes a cartridge body 110, first carriers 150, a second carrier 140, third carriers 130 and diffusing bodies 120.

(12) The cartridge body 110 includes a pair of vent holes 111 and 112 formed at one side to make air flow in and out and a space which is a passage formed therein to allow the inflow air to flow. In more detail, the vent holes 111 and 112 are arranged at the upper portion of the cartridge body 110 side by side, and the passage formed by the inner space of the cartridge body 110 has at least one bent section formed till the inflow air is discharged out. In this instance, the cartridge body 110 is joined with a lower body 160 to form an assembly.

(13) The cartridge body 110 is formed in a shape of an approximately rectangular parallelepiped, and the vent holes 111 and 112 are formed side by side. A stepped portion which is a bent section is formed between the vent holes 111 and 112. That is, the vent holes 111 and 112 which respectively form an air inlet and an air outlet of the cartridge body 110 are respectively arranged at one side and the other side of the cartridge body 110. The air passage connects the vent holes 111 and 112 with each other is formed to have at least one bent section.

(14) Therefore, the aroma-diffusing cartridge for a vehicle according to the present invention forms the structure that flowing air within a limited space stays in the cartridge body 110 as long as possible so as to increase aroma-diffusing effect. In this instance, the cartridge body 110 is not limited to the shape of the rectangular parallelepiped but may have another shape.

(15) A plurality of carriers which contain and emit aroma according to the air flow passage are arranged and mounted inside the cartridge body 110. The carriers are formed to have different aroma containing structures so that they have different aroma containing and emitting terms from one another.

(16) The first carriers 150 which are disposed inside the cartridge body 110 are formed in a shape of an approximately rectangular parallelepiped and are located at the lowest portion of the cartridge body 110. The first carrier 150 is in a honeycomb structure which contains aroma-concentrated gel. The first carrier 150 contains aroma for a relatively long term. The honeycomb structure and the aroma-concentrated gel may help the first carrier 150 hold aroma for a long term.

(17) The first carriers 150 are in a pair and are spaced apart from each other. Finally, the first carriers 150 are respectively located at the lower portions of the vent holes 111 and 112. Therefore, the air flowing into one vent hole 111 is discharged out through the other vent hole 112 while sufficiently passing the first carriers 150. In this instance, a coating layer 151 may be formed on at least one side of the first carrier 150. The coating layer 151 makes the aromatic components contained in the first carrier 150 be maintained longer.

(18) The second carrier 140 is put on the upper portion of the first carriers 150 and is made of porous resin, such as porous ceramics and polymer to contain aroma for a relatively short term. Through the porous structure and the structure for containing liquid aroma, the second carrier 140 can contain aroma for a short term.

(19) Furthermore, the second carrier 140 is formed in a plate type to completely cover the upper portions of the first carriers 150. Therefore, the air introduced into one of the vent holes 111 and 112 passes the second carrier 140 without fail, and then, goes by way of the first carriers 150. As described above, because the flowing air passes all of the second carrier 140 which has the short-term aroma containing property and the first carriers 150 which have the long-term aroma containing property. The aroma-diffusing cartridge for a vehicle according to the present invention can maintain stable and continuous aroma emission complexly.

(20) The third carriers 130 are in the form of pellets and have a hollow form which contains aroma-concentrated gel. The third carriers 130 is smaller than the first carriers 150, and charge an upper space of the second carrier 140 in the plural. The third carriers 130 contain aroma for a relatively medium term. That is, the third carriers 130 contain concentrated gel-type aroma which is maintained longer than liquid type aroma. The third carriers 130 are smaller in form and size than the first carriers 150 of a honeycomb form and have the aroma containing term shorter than the first carriers 150.

(21) Finally, the air introduced into one of the vent holes 111 and 112 goes by way of the first carriers 150 after passing through the third carriers 130 and the second carrier 140 without fail. As described above, while the flowing air passes through all of the third carriers 130 which have the aroma containing property of the medium term, the second carrier 140 which has the aroma containing property of the short term, and the first carriers 150 which have the aroma containing property of the long term, the aroma-diffusing cartridge according to the present invention can maintain stable and continuous aroma emission complexly.

(22) Moreover, preferably, the space formed between the first carriers 150 is charged with additional third carriers 130. Finally, the third carriers 130 closely charge the space which is not charged with the first carriers 150 and the second carrier 140 so as to emit aroma more continuously and stably. Additionally, a coating layer may be formed on at least one side of the third carriers 130. The coating layer 131 makes the aromatic components contained in the third carriers 130 last longer.

(23) In short, the carriers include: the first carriers 150 arranged on the air passage of the cartridge body 110; the third carriers 130 arranged to be adjacent to a pair of the vent holes 111 and 112 which form the air inlet and the air outlet; and the second carrier 140 arranged between the first carriers 150 and the third carriers 130.

(24) The first carriers 150 are longer in the aroma containing and emitting term than the second carrier 140 and the third carriers 130, and are arranged at a position which does not directly faces the vent holes 111 and 112. The second carrier 140 has an aroma containing structure that the aroma containing and emitting term is shorter than that of the first carriers 150 and the third carriers 130, and is arranged between the first carriers 150 and the third carriers 130. The third carriers 130 has an aroma containing structure that the aroma containing and emitting term is shorter than that of the first carriers 150 and longer than that of the second carrier 140, and is arranged to be adjacent to the vent holes 111 and 112.

(25) Moreover, the first carriers 150 are arranged on the air passage of the cartridge body 110 in the plural, and the third carriers 130 are additionally arranged between the first carriers 150 arranged on the air passage. Furthermore, the first carriers 150, the second carrier 140 and the third carriers 130 are arranged in such a way that the air introduced into the cartridge body 110 through the vent hole 111 passes the first carriers 150, the second carrier 140 and the third carriers 130 in turn at least twice.

(26) Finally, the cartridge body 110 has at least two carriers which are disposed inside the cartridge body 110 and have different aroma containing terms from each other, in order to provide stable and continuous aroma-diffusing performance within the limited space.

(27) The diffusing bodies 120 have a mesh structure formed to cover the vent holes 111 and 112 and serve to introduce uniform diffusion of the air which flows in and out. Preferably, the diffusing body 120 is arranged above the upper portions of the third carriers 130 inside the space of the cartridge body 110.

(28) The air introduced through one vent hole 111 flows to the third carriers 130, the second carrier 140 and the first carriers 150 in order after passing through the diffusing body 120, and then, passes through the third carriers 130 after moving in the horizontal direction. After that, the air flows through the first carriers 150, the second carrier 140 and the third carriers 130 in order, passes the diffusing body 120, and then, is discharged out via the other vent hole 112.
