Description

Binary structure cooling filter and composite suction material rod

The new type is related to cigarettes, and more specifically refers to a dual-structure cooling filter tip and a composite smoking material rod.

In addition to the cigarette core (column) and the filter material, the aerosol suction material rod of the non-combustion heating tobacco product also needs to set a cooling section between the cigarette core (column) and the filter material to reduce the high temperature of the flue gas. Improve suction taste.

The existing cooling section is usually made of cooling materials such as aluminum foil or plastic. The manufacturing method enables long cooling plates or corrugations with radial configuration to be made from materials that can be cooled such as aluminum foil or plastic, so as to provide a large contact area for heat exchange. Regardless of whether it is the cooling section of the cooling material such as aluminum foil or plastic, it is necessary to make a complex structure to strengthen the cooling, so it becomes a relatively high-cost accessory in the filter structure. In addition, if the cooling section is poorly made, there will be a problem of increasing the suction resistance.

In addition, in order to achieve the aforementioned cooling effect, an additional cooling section in the aerosol suction material rod is added, which is equivalent to adding a manufacturing process when making the filter structure, and further increases the manufacturing cost of the aerosol suction material rod.

In view of the above problems, the present invention proposes a dual-structure cooling filter and a composite suction material rod to provide different cooling schemes, simplify the filter structure and reduce costs.

A dual-structure cooling filter comprises a hollow section and a filter section. The hollow section has an air outlet end and an air intake end, and the hollow section has a hollow passage that communicates with the air outlet end and the air intake end. The filter section is connected to the outlet end of the hollow section, so that the hollow channel is connected to the filter section. Wherein, the length of the hollow section is greater than 15mm, and the length ratio of the hollow section to the filter section is greater than 1. The hollow section is made of breathable material.

The fragrance-absorbing threads may release the fragrance directly to the filter section 120 for incorporation into the aerosol. The filter section 120 can be easily deformed by extrusion. Therefore, the flavored gel mass or flavored capsule containing flavor can be crushed to allow the flavor to be dispersed in the fibers of the filter section 120 .

The flavoring material in the flavoring material block 130 can be the flavor liquid of cantaloupe, peach, lychee, lime, strawberry, grape, bergamot, etc. as mentioned above, and it is considered whether to add cool flavor such as mint and other flavoring materials. . The flavor of the flavor used in the aerosol generating section 200 may be different from the flavor of the block 130 of flavoring material, allowing for more flavor variation in the rod 1 of composite smoking material. For example, when the flavoring material block 130 is not used (the flavored capsule is not crushed), the smoke has flavors such as passion fruit flavor, comprehensive fruit flavor, parmanth flavor, etc., and other flavors are added after the flavoring material block 130 is used.

The outer end of the filter section 120 can be further added with materials or structural changes can be made to produce changes in shape or function.
