Y-Shaped Cellulose Acetate Filter for HNB Draw Resistance

The patent introduces a cooling element as an intermediary component positioned between the heating element and the filter element. This cooling element acts as a thermal mediator that protects the filter from direct exposure to high temperatures while allowing the filter to remain in its optimal position for filtering aerosol. The cooling element absorbs excess heat and prevents it from reaching the filter element, thereby resolving the contradiction between maintaining close proximity for effective filtering and preventing thermal damage.

The patent applies local quality by creating regions of different filtration densities within the filter element. The filter structure incorporates varying pore sizes and material densities in different zones, allowing optimal balance between filtration efficiency and airflow. The three-dimensional network structure provides high filtration performance in critical areas while maintaining open pathways for adequate airflow, thus resolving the contradiction between removing harmful components and obstructing air passage.

The patent employs parameter changes by carefully selecting and controlling the chemical and physical parameters of the filter material. The polymer matrix and filler materials are chosen to have neutral flavor characteristics, and their composition ratios are optimized to maintain filter functionality without imparting unwanted flavors. The surface area-to-volume ratio and porosity parameters are adjusted to ensure the filter performs its protective function while remaining flavor-neutral, thus resolving the contradiction between filter effectiveness and taste preservation.
