Abstract

Disclosed is an aroma-diffusing cartridge for a vehicle wherein the structures of the cartridge and a carrier of an aroma are so optimized that the capacity of the carrier for carrying the aroma may become excellent together with stable and continuous performance of diffusing the aroma. An aroma-diffusing cartridge for a vehicle comprises: a cartridge body having one side formed with a pair of air holes for receiving and discharging air, and an internal space for circulating the received air; and at least two carriers put in the cartridge body with different duration of keeping an aroma. Thus, the capacity of the carriers for carrying an aroma is excellent together with stable and continuous performance of diffusing the aroma in a limited space, so that the air in the vehicle may be kept agreeable for a long time.

Claims

1. An aroma-diffusing cartridge for a vehicle comprising:

a cartridge body (110) which has a pair of vent holes (111, 112) 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; and

a plurality of carriers arranged and mounted inside the cartridge body (110) to contain and emit aroma according to an air flow path,

wherein the carriers have different aroma containing structures that are different in aroma containing and emitting term from one another.

2. The aroma-diffusing cartridge according to claim 1, wherein the vent holes (111, 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), and the air passage which connects the vent holes (111, 112) has at least one bent section.

3. The aroma-diffusing cartridge according to claim 2, wherein the carriers comprise:

first carriers (150) arranged on the air passage of the cartridge body (110);

third carriers (130) arranged to be adjacent to a pair of the vent holes (111, 112) which respectively form an air inlet and an air outlet; and

a second carrier (140) arranged between the first carriers (150) and the third carriers (130).

4. The aroma-diffusing cartridge according to claim 3, wherein the first carriers (150) are longer in aroma containing and emitting term than the second carrier (140) and the third carriers (130), and

wherein the first carriers (150) which are the longest in the aroma containing and emitting term are arranged at a position which does not directly touch the vent holes (111, 112).

5. The aroma-diffusing cartridge according to claim 3, wherein 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

wherein the second carrier (140) which is the shortest in the aroma containing and emitting term is arranged between the first carriers (150) and the third carriers (130).

6. The aroma-diffusing cartridge according to claim 3, wherein 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 is longer than that of the second carrier (140), and

wherein the third carriers (130) which are intermediate in the aroma containing and emitting term between the first carriers and the second carrier are arranged to be adjacent to the vent holes (111, 112).

7. The aroma-diffusing cartridge according to claim 3, wherein the first carriers (150) are arranged on the air passage of the cartridge body (110) in the plural, and

wherein the third carriers (130) are additionally arranged between the first carriers (150) arranged on the air passage.

8. The aroma-diffusing cartridge according to claim 3, wherein 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.

9. The aroma-diffusing cartridge according to claim 8, wherein 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, and then, is discharged out through the first carriers (150), the second carrier (140) and the third carriers (130) via the other vent hole (112) in order.

10. The aroma-diffusing cartridge according to claim 3, wherein the carriers comprise:

first carriers (150) having a honeycomb structure of a gel type;

a second carrier (140) made of porous resin which contains liquid aroma; and

third carriers (150) having a hollow form which contains gel.

11. The aroma-diffusing cartridge according to claim 2, further comprising:

diffusing bodies (120) of a mesh structure which are formed to cover the vent holes (111, 112) and serve to introduce uniform diffusion of the air which flows in and out.

12. The aroma-diffusing cartridge according to claim 3, wherein each of the first carriers (150) and each of the third carriers (130) respectively have coating layers (151) and (131) formed on at least one side thereof.
