Description

[Technical field]

[0001] The present invention relates to the field of fragrance technology, and in particular to an hourglass-shaped fragrance structure. [Background technology]

[0002] An air freshener box is a product used to improve indoor air quality, usually a small box or container containing one or more substances that can emit fragrance or absorb pollutants. These substances can absorb or neutralize indoor odors, smoke, harmful gases, etc., thereby purifying the air and making the indoor environment more flush and comfortable.

[0003] In the prior art, the fragrant in the fragrant structure is usually arranged upward, and the fragrant will decrease over time. Therefore, to ensure that all the fragrant is released through the wick, the wick immersed in the liquid needs to pass from the liquid surface to the bottom. However, as the fragrant gradually decreases, the liquid surface of the fragrant drops, and the contact area with the wick becomes smaller and smaller, which causes the release of the fragrant to be uneven and reduces the efficiency of purifying the air.
