Aerosol-generating article and sealing unit therefor, aerosol-generating system
By using a sealing component made of phase change material and a high-barrier shell in aerosol-generating products, the problems of the sealing unit being unable to seal volatile small molecules for a long time and the release being inaccurate are solved, achieving stable preservation of the contents and precise release at specific temperatures, thus improving the suction experience.

AI Technical Summary
Technical Problem
Existing sealing units cannot effectively seal volatile small molecule contents for a long time, and the release mechanism is not precise, resulting in serious aroma loss and poor inhalation experience.
Method used
The sealing component, made of phase change material, combined with a high-barrier shell and flow channel, enables precise and controllable release of contents through temperature changes.
Benefits of technology
It achieves long-term stable sealing of volatile small molecule contents and precise release at specific temperatures, improving the sensory experience and product quality of aerosol-generated products.

Abstract
Provided are an aerosol generating article, a sealing unit therefor, and an aerosol generating system, the sealing unit including a housing, contents, a flow passage, and a blocking member, the flow passage being provided on the housing, the contents being sealed inside the housing, the contents being able to flow from the housing to the aerosol generating article only through the flow passage, and the blocking member matching the shape of the flow passage and being caught in the flow passage so that the contents cannot flow out of the housing. The sealing unit is provided inside the aerosol generating article, and the blocking member is made of a phase change material, so that the sealing unit can automatically release the sealed contents by the temperature of smoke, can long-term store small-molecule volatile contents, and can precisely and controllably release effective components at a specific puffing temperature, thereby improving the puffing taste.
