Embodiment 1

[0034] The aerosol cooling filter unit of this embodiment adopts silicone resin polymethyl silicone resin to form a hollow tube by injection molding according to a conventional injection molding process. The air pressure drop generated by the hollow tube along the longitudinally extending channel is 0 Pa / mm, Further cutting to form small sections of 25 mm can obtain a cooling filter unit that can effectively reduce the temperature of the airflow.

[0035] The low-temperature filter unit of this embodiment is used to prepare low-temperature cigarettes with binary filters according to the existing technology, such as figure 1 As shown, the low-temperature cigarette of this embodiment includes an aerosol generating section 10 and a filter section 20, and the filter section 20 further includes an upstream filter section 21 and a mouth-end filter section 23, and the upstream filter section 21 is the cooling filter section of this embodiment. unit.

[0036] The upstream filter sect...

Embodiment 2

[0041] The aerosol cooling filter unit of this embodiment uses silicone rubber methyl vinyl silicone rubber to make a silicone rubber sheet according to a conventional process, and the silicone rubber sheet is embossed or folded or gathered to form a uniform strip with multiple channels in the longitudinal direction Rod, cut the rod to obtain a cylinder with a porous cut surface and a length of 144mm, or cut the silicone rubber sheet into a cylinder with a width of 144mm, and then gather it to form a cylinder with a longitudinal multi-channel structure, that is, to obtain this embodiment. Example aerosol cooling filter unit.

[0042] After measurement, the air pressure drop produced by the cooling filter unit along the longitudinally extending channel is 0.4 Pa / mm, and then further cut to form a small section with a length of 6mm, and the small section is prepared according to the existing technology. Three-element filter low-temperature cigarettes, such as figure 2 shown. T...

Embodiment 3

[0047] The aerosol cooling filter unit of the present embodiment is specifically as follows, take a roll paper material with a width of 106mm, evenly smear, spray, and print fluid organic silicone resin polyaryl silicone resin on the roll paper material, and then use it at 50 ~ Dry and solidify at 100°C to prepare a silicone composite film. The silicone composite film is embossed or folded or gathered to form a continuous cylindrical strip with multiple longitudinal channels and uniformity. The cylindrical strip is cut to obtain a porous cut surface and a length of A cylinder of 144 mm can also be formed by cutting the organosilicon composite film into a width of 144 mm, and then gathering to form a cylinder with a longitudinal multi-channel structure, that is, the aerosol cooling filter unit of this embodiment is obtained.

[0048] After measurement, the air pressure drop produced by the cooling filter unit along the longitudinally extending channel is 0.5 Pa / mm, and then furt...

Abstract

The invention relates to the technical field of heat-not-burn cigarettes, in particular to an aerosol cooling filtration unit and a low-temperature cigarette. The aerosol cooling filtration unit is ahollow pipe or a honeycomb-shaped empty pipe made of an organosilicon material in an injection molding or extrusion molding mode, or is a cylinder provided with a longitudinal multi-channel structureand formed by organosilicon composite film sheets in an embossing, folding or gathering mode, and or is a hollow pipe formed by organosilicon composite film sheets wound through a spiral technology. The aerosol cooling filtration unit adopts the organosilicon material with cooling and heat absorbing functions, the temperature of aerosol can be decreased through the effect of absorbing a lot of heat by the organosilicon material, the physical properties of the organosilicon material are stable, thus adhesion and collapse are not likely to occur in the aerosol passing process, longitudinal channels are always kept smooth, smooth flowing of the aerosol is kept, and the smoking experience feeling of a user is effectively improved.

Description

technical field [0001] The invention relates to the technical field of heat-not-burn cigarettes, in particular to an aerosol cooling filter unit and low-temperature cigarettes. Background technique [0002] It is well known that smoking is harmful to health, especially with the continuous development of social economy and the continuous improvement of living standards, people pay more and more attention to their own health problems. For the tobacco industry, reducing tar and harm is an important trend in the future development of the tobacco market , It is also the current mainstream development direction of tobacco. Heat-not-burn cigarettes emerged as the times require. Its principle is to provide consumers with nicotine and tobacco characteristic aroma through heat-not-burn tobacco to meet consumers' needs. At the same time, this "heat-not-burn" method makes tobacco It is heated at a low temperature (generally 300-500°C), which can greatly reduce the release of tar and ha...
