Abstract

An air freshener for a vehicle includes a housing having an air inlet and an air outlet at both ends thereof. A perfume container is provided inside the housing, in which a plurality of aromatics having different physical states are laminated. An aromatics laminated at an uppermost layer is evaporated by air passing through an interior of the housing.

First claim

What is claimed is:

1. An air freshener device for a vehicle, comprising:
a housing having an air inlet formed at one end of the housing and an air outlet formed at another end of the housing; and
a perfume element provided inside the housing, in which the perfume element having layers of a plurality of aromatics having different physical states and laminated,
wherein the perfume element comprises:
a first aromatics laminated on an uppermost layer of the perfume element, which is evaporated by air passing through an interior of the housing;
a second aromatics having a lifespan longer than that of the first aromatics in its physical state; and
a porous filter disposed between the first aromatics and the second aromatics,

wherein the first aromatics is in a gel state and the second aromatics is in a solid state, and
wherein the porous filter is laminated on one surface of the second aromatics, and the opposite surface of the second aromatics is seated on an inner surface of the housing.

2. The air freshener device of claim 1 , wherein an aromatics housing member is provided in which the first aromatics is accommodated.

3. The air freshener device of claim 2 , wherein the aromatics housing member is made of a porous material and is connected to the porous filter.

4. The air freshener device of claim 3 , wherein the aromatics housing member is made of a ceramic porous material which has a porous surface area.

5. The air freshener device of claim 2 , wherein the aromatics housing member has at least one hole formed along a length direction thereof, into which the first aromatics is inserted.

6. The air freshener device of claim 5 , wherein an upper surface of the first aromatics in the aromatics housing member is exposed to the air passing through the interior of the housing.

7. The air freshener device of claim 1 , wherein a reception portion is provided on the inner surface of the housing, which surrounds edges of the second aromatics.

8. The air freshener device of claim 1 , wherein air is introduced into the air inlet by an air blower of an air conditioner and the air outlet is connected to an interior of the vehicle.

9. The air freshener device of claim 8 , wherein the air introduced from the air inlet is discharged to the air outlet.

10. The air freshener device of claim 1 , wherein the porous filter is a membrane having fine holes, through which only an evaporated perfume is permissible.

11. The air freshener device of claim 1 , wherein one surface of the first aromatics is connected to the porous filter laminated on the second aromatics.
