Description

Hollow binary structure filter tip and composite suction material rod

The new type relates to cigarettes, and more specifically refers to a hollow binary structure filter and a composite smoking material rod.

In addition to cigarette cores (columns) and filter materials, aerosol smoking material rods for non-combustible heated tobacco products also require a cooling section between the tobacco cores (columns) and filter materials to reduce the high temperature of the flue gas. Improves the mouthfeel of suction.

The existing cooling section is usually made of cooling materials such as aluminum foil paper or plastic. The manufacturing method is to make long cooling plates or folds with a radial configuration from a temperature-reducing material such as aluminum foil paper or plastic to provide a large contact area for heat exchange. Regardless of the cooling section of the temperature-reducing material such as aluminum foil paper or plastic, it is necessary to fabricate a complex structure to enhance cooling, so it becomes a relatively costly accessory in the filter structure. In addition, if the cooling section is poorly manufactured, there will be a problem of increasing suction resistance.

In addition, the additional addition of the cooling section in the aerosol suction material rod is equivalent to adding a manufacturing process when manufacturing the filter structure, which further increases the manufacturing cost of the aerosol suction material rod.

In view of the above problems, the present invention proposes a hollow binary structure filter and a composite suction material rod to provide different aerosol cooling solutions, simplify the filter structure and reduce costs.

The present invention provides a hollow binary structure filter, which includes a hollow section and a filter section. The hollow section has an outlet end and an inlet end, and the hollow section has a hollow passage that communicates with the outlet end and the inlet end. The filter section is connected to the outlet end of the hollow section, and the hollow channel is connected to the filter section; wherein, the length of the hollow section is greater than 15 mm, and the length ratio of the hollow section to the filter section is greater than 1.

In at least one embodiment, the hollow section is made of fiber material.

In at least one embodiment, the fiber material of the hollow section is pulp fiber or acetate fiber.

In at least one embodiment, the hollow section is made of metal.

In at least one embodiment, the hollow section is made of aluminum foil.

In at least one embodiment, the filter section is made of fibers.

In at least one embodiment, a flavoring material block with flavoring flavor is further included in the filtering section.

In at least one embodiment, the flavoring material block is a flavor-absorbing silk thread, a flavoring gel block, or a flavoring-containing flavoring capsule.

The present invention further proposes a rod of composite suction material, comprising an aerosol generating section, the aforementioned hollow binary structure filter and a roll of paper. The aerosol generating section is used to be heated to release aerosol. The aerosol generating section is connected to the intake end of the hollow section. A tubular structure wound by a roll of paper and covering the aerosol generating section and the hollow binary structure filter to form a composite suction material rod.

In at least one embodiment, the material of the aerosol generating section is natural tobacco leaves, artificial tobacco leaves, tobacco bones, tobacco shreds, duplicate tobacco sheets, tobacco sand, or any combination of the foregoing components.

Unlike the prior art, where a cooling section pre-formed with various materials is added, the new model only uses the hollow binary structure of the hollow section and the filtering section. By extending the length of the hollow section, the effect of cooling the aerosol (flue gas) is achieved. The hollow binary structure omits the cooling section configuration, and can simplify the manufacturing process of the filter, while reducing the manufacturing cost of the filter. The hollow section will not form unnecessary obstruction to the air flow, and can make the composite suction material rod be sucked smoothly without suction resistance.

Please refer to FIG. 1, FIG. 2 and FIG. 3, which is a hollow binary structure filter 100 disclosed in the first embodiment of the present invention, which is used to combine a roll of paper 300 with an aerosol generating section 200 to form a Composite suction material rod 1. The composite smoking material rod 1 may be a cigarette, including a burning-heating cigarette and a non-burning-heating cigarette, for being used alone. The aerosol generation section 200 is used to release aerosol (flue gas) by heating, and the hollow binary structure filter 100 is used to adsorb aerosols, because the aerosol generation section 200 is heated to generate solid particles or tar.

As shown in FIGS. 2 and 3, the hollow binary structure filter 100 includes a hollow section 110 and a filter section 120. The hollow section 110 is connected to the filter section 120 to form a binary structure.

As shown in FIGS. 2 and 3, the hollow section 110 has an outlet end 112 and an intake end 114, and the hollow section 110 has a hollow passage 116. The hollow passage 116 passes through the hollow section 110 and communicates with the air outlet end 112 and the air inlet end 114. The hollow channel 116 is used to pass the aerosol (flue gas) generated by the aerosol generating section 200 by heating, and the hollow section 110 is extended to have a sufficient length for cooling when the aerosol (flue gas) passes, so that the temperature is suitable for suction .

The hollow section 110 may have a certain thickness, not necessarily a thin shell tube structure. In actual production, the hollow section 110 may be made of fiber material or metal. The fiber material may be pulp fiber, that is, the hollow section 110 may be a paper tube; the fiber material may also be acetate fiber, and a hollow channel 116 is opened in the middle. Metal can be easily processed aluminum foil. Metal has good thermal conductivity properties, and helps to cool the aerosol (smoke).

As shown in FIGS. 2 and 3, the filter section 120 is connected to the outlet end 112 of the hollow section 110, and the hollow passage 116 is connected to the filter section 120. The filtering section 120 is mainly used for the user to suck the composite suction material rod 1 so that the aerosol is sucked through the hollow channel 116, and further passes through the filtering section 120 to adsorb solid particles or tar in the aerosol. Then release the aerosol into the user's mouth.

In a specific embodiment, a harder and less air-permeable filter paper or filter roll paper may be used, which is wound around the filter section 120 and the hollow section 110 to fix and connect the hollow section 110 and the filter section 120; but The present invention does not exclude other ways to connect the hollow section 110 and the filter section 120; for example, when the composite suction material rod 1 is subsequently made, the hollow section 110, the filter section 120, and the aerosol generating section 200 are directly wound with a roll paper 300, And the purpose of connecting the hollow section 110 and the filtering section 120 is achieved.

As shown in FIGS. 2 and 3, in order for the aerosol to cool down in the hollow channel 116, the length L1 of the hollow section 110 needs to be extended to a sufficient length, and it needs to have an appropriate length ratio with the length L2 of the filter section 120. In a specific embodiment, the length L1 of the hollow section 110 is greater than 15 mm, and the length ratio between the length L1 of the hollow section 110 and the length L2 of the filter section 120 is greater than 1, which can ensure that the aerosol is indeed cooled through the hollow channel 116 .

As shown in FIG. 1, the composite suction material rod 1 includes the aforementioned hollow binary structure filter 100, an aerosol generating section 200 and a roll of paper 300. The aerosol generating section 200 is connected to the intake end 114 of the hollow section 110. A tubular structure wound by the roll paper 300 covers the aerosol generating section 200 and the hollow binary structure filter 100 to form the composite suction material rod 1.

As shown in FIG. 1, the aerosol generating section 200 is used to be heated by combustion or non-combustion to generate aerosol, that is, smoke; and the hollow binary structure filter 100 is used for the composite suction material rod 1, and Filter aerosol/smoke. The material of the aerosol generating section 200 can be natural tobacco leaves, artificial tobacco leaves, tobacco bones, tobacco shreds, duplicate tobacco sheets, cigarette sand, or any combination of the foregoing components, and is wrapped and wrapped by cigarette paper; the cigarette paper can be Part of roll paper 300. In addition to tobacco-containing products, the aerosol generating section 200 can be added with various fruit flavors and flavors, such as cantaloupe, peach, lychee, lime, strawberry, grape, bergamot and other flavors.

As shown in FIG. 1, the hollow section 110 is used to prevent the filter section 120 from directly contacting with the aerosol generating section 200, and to isolate the high heat generated when the aerosol generating section 200 is heated or burned to avoid the generation of aerosol generated by heat The section 200 directly heats the filtering section 120, while the hollow section 110 provides a hollow channel 116 of sufficient length so that the aerosol can be cooled while passing through the hollow channel 116 and cooled to a temperature suitable for suction.

Please refer to FIG. 4, which is a hollow binary structure filter 100 and a composite suction material rod 1 disclosed in the second embodiment of the present invention. The hollow dual structure filter 100 of the second embodiment further includes a flavoring material block 130 disposed in the filter section 120. The flavoring material block 130 has flavoring flavors, which can give the aerosol (smoke) additional flavor when the aerosol passes through. The aforementioned flavoring material block 130 is a silk thread for adsorbing flavoring, a gel block containing flavoring, or a flavoring capsule containing flavoring. The thread that adsorbs the fragrance can directly release the fragrance to the filter section 120 to be incorporated into the aerosol. The filter section 120 can be easily squeezed and deformed. Therefore, the gel block containing the flavoring material or the flavoring capsule containing the flavoring material can be crushed and crushed, so that the flavoring material is dispersed in the fibers of the filter section 120.

The flavoring materials in the flavoring material block 130 can be flavoring liquids such as cantaloupe, peach, lychee, lyme, strawberry, grape, bergamot, etc., and whether cooling flavors such as mint are added . The flavor of the flavor material used in the aerosol generating section 200 may be different from the flavor material of the flavoring material block 130, so that the composite smoking material stick 1 has more flavor changes. For example, when the flavoring material block 130 is not used (the flavoring capsule is not crushed), the smoke has flavors such as passion fruit flavor, comprehensive fruit flavor, and barberry flavor. However, the flavoring material block 130 adds other flavors.

The external end of the filter section 120 can be further added with material or structurally changed, thereby causing a change in shape or function.

Unlike the prior art where a cooling section pre-formed with various materials is added, the new model only uses the hollow binary structure of the hollow section 110 and the filter section 120. By extending the length L1 of the hollow section 110, cooling of the aerosol (flue gas) is achieved ). The hollow binary structure omits the cooling section configuration, and can simplify the manufacturing process of the filter, while reducing the manufacturing cost of the filter. The hollow section 110 does not form an unnecessary barrier to the airflow, and can enable the composite suction material rod 1 to be sucked smoothly without suction resistance.
