An aerosol generating product includes an aerosol atomizing element and a smoke cooling element, and the smoke cooling element is located downstream of the flow direction of the smoke generated by the aerosol atomizing element. A filter element is located downstream of the flow direction of the smoke through which the smoke cooling element passes; or a hollow element located upstream of the flow direction of the smoke through which the smoke cooling element passes. The smoke cooling element is composed of particles, and the structure includes a gap for smoke of a cigarette to pass through. The gap through which cigarette smoke can pass is a three-dimensional and non-linear gap. The structure is in the form of rods. When the smoke aerosol passes through the cooling element, ensuring the smoke to pass through smoothly.

Composite materials having high cohesive strength, formed from at least one polymer and from at least one compound selected from among mineral oxides, aluminosilicates and active carbon, are characterized by a mean particle size of at least 100 mm, a pore volume (Vd1) formed by pores having a diameter ranging from 3.6 to 1,000 nm, equal to at least 0.2 cm.sup.3/g, a cohesive strength such that its content of particles having a size of less than 100 mm, obtained after being subjected to an air pressure of 2 bar, of less than 1.5%, preferably 0.0%, by volume; such composite materials are formed into useful liquid supports, catalyst supports, additives, or liquid or gas filters, in particular into cigarette filters.

A filter device including a Bernoulli element is provided. The filter device includes a housing, a plurality of permeable membranes positioned in association with the housing to create a plurality of chambers in the housing, and a Bernoulli element positioned within one chamber, wherein the Bernoulli element causes airflow and pressure to vary within the one chamber when fluid comprising smoke is drawn into the filter device.

A cone shaped cigarette with hard tip and method for manufacture where a cone shaped paper encasement can contain shredded botanical material and a hard tip member having an inhaling aperture is inserted into the small end of the cone shaped paper encasement by an FDA approved adhesive. A filter member can be inserted into the tip of the hard tip member. A preferred embodiment includes the hard tip member being made of borosilicate glass. The hard tip member can be cylindrical in shape or cone shaped to match the side walls of the paper encasement. A preferred embodiment includes the glass hard tip member being transparent and the filter member is colored allowing the filter member to be viewed through the glass hard tip member.

The invention discloses a granular cigarette, comprising a tobacco tube encapsulated with tobacco particles; one end of the tube is provided with a filtering component and the other end a sealing component; the tobacco particles are arranged between the filtering and the sealing components. The filtering component can adopt traditional filtering cotton or filtering silica gel strip; the sealing component can adopt aluminum foil, tobacco sheet, self-closing silica gel plug, and glue film. A capsule packaging can be further adopted for the tobacco particles to solve the problem that the particles easily fall out during production. The invention replaces the low-temperature non-burning cigarette with a thin-film technology by encapsulating a granular cigarette, which has the advantages of simple production process, sufficient heating, uniform smoke, and the smoke can shuttle between particles; the problem of easy falling out of particles can be solved by the filtering and the sealing components.

A cigar holder assembly includes a filter holder that includes: a first filter holder piece having a first end to connect to a smoking machine and a second end, and a second filter holder piece having a first end and a second end, a first opening extending axially into the first end and a second opening extending axially into the second end, and the second end of the first filter holder piece and the first end of the second filter holder piece fit together. The assembly includes a cigar holder having a first end and a second end to receive a cigar, and the second end of the second filter holder piece and the first end of the cigar holder fit together; and a seal has an opening that extends through its entire thickness, the seal configured to fit in the opening in the first end of the cigar holder.

A filter device including a Bernoulli element is provided. The filter device includes a housing, a plurality of permeable membranes positioned in association with the housing to create a plurality of chambers in the housing, and a Bernoulli element positioned within one chamber, wherein the Bernoulli element causes airflow and pressure to vary within the one chamber when fluid comprising smoke is drawn into the filter device.

A harm-reducing cigarette filter, a method for preparing the cigarette filter and an application of the cigarette filter are disclosed, and the cigarette filter includes six layers from outside to inside: a first layer includes filter cotton with an activated carbon, a second layer includes a five-hole glue, a third layer includes filter cotton, a fourth layer includes filter particles, a fifth layer includes filter cotton with filter fluid, and a sixth layer includes a silica gel cover. The cigarette filter is injection molded by utilizing non-toxic polycarbonate (PC) or polymethylmethacrylate (PMMA). The experimental research shows that the cigarette filter has good adsorption effect on tar and nicotine, and reduces smoking people to absorb harmful substance.

There is provided an adsorbent material comprising a porous carrier material having pores with a diameter greater than 20 nm and carrying additive particles on its external surface, wherein the additive particles comprise an additive and have a diameter of greater than 20 nm. There is also provided a smoking article filter element comprising such an adsorbent material, a smoking article comprising such an adsorbent material, and a method of preparing such an adsorbent material.

Smoking articles which involve the use of amphiphile-modified sorbents are disclosed. The amphiphile-modified sorbent has at least one amphiphilic compound bound to an inorganic molecular sieve substrate. The amphiphile-modified sorbent selectively removes certain constituents from cigarette smoke, while maintaining other constituents, such as those that contribute to flavor. Methods for making cigarette filters and smoking articles using amphiphile-modified sorbents, as well as methods for smoking a cigarette containing an amphiphile-modified sorbent, are also provided.
