Heat-Not-Burn Aerosol-Generating Article, Product and Manufacturing Method Thereof

The present disclosure relates to a field of heat-not-burn non-tobacco and tobacco products, and more particularly to a heat-not-burn aerosol-generating article, product and manufacturing method thereof.

At present, the current trend is for new type non-tobacco and tobacco products such as heat-not-burn (HNB), but an aerosol-generating article production process of HNB non-tobacco products and tobacco products on the market is complex, and the use of more tobacco production devices cost a certain amount of manpower and financial resources. And most aerosol-generating articles adopt filament, flake, or other shapes such as granular. When the heater is used for heating and suction, the suction resistance is too large, and an amount of smoke is too small, which affects the suction effect.

Existing aerosol-generating articles are usually in the shape of filaments, flakes, or granules. When filling them into a smoke tube, manual filling is usually required, which is inconvenient to operate and an amount of filling is not easy to control. Even if it is converted to mechanized operation, it will be more difficult to control a filling operation, the automatic machinery will be very complicated, the filling operation will be difficult to control, and a filling amount will be difficult to achieve consistent.

In view of this, it is necessary to provide a heat-not-burn (HNB) aerosol-generating article, product and manufacturing method thereof, which are easy to operate to fill into smoke tube and have a good suction effect.

An HNB aerosol-generating article is used to be loaded into a tube of a HNB non-tobacco or tobacco product, which includes aerosol-generating raw material, aerosol-generating agent, and water. The aerosol-generating raw material, the aerosol-generating agent, and the water are mixed and blended into paste, so that the HNB aerosol-generating article is in a shape of paste stick. Wherein the paste stick HNB aerosol-generating article is injected into the HNB cartridge tube and has internal pores to allow aerosol to penetrate and exude, a porosity thereof is 40-75% when heating and drying, so as to reduce the suction resistance to 0.75-1.5 Kpa to make the aerosol to be smoothly released during the smoking process.

In some embodiments, the HNB aerosol-generating article is composed of following parts by weight: 40-80 parts of the aerosol-generating raw material, 30-60 parts of the aerosol-generating agent, and 30-50 parts of the water.

In some embodiments, the aerosol-generating raw material is a combination of one or more of herbal spice or Chinese medicine raw material, the herbal spice is preferably a combination of one or more of tea, lotus leaf, mint, licorice, clove, dried lemon, dried orange,star anise,mulberry leaf, bay leaf,orange,-tangerine peel,lavender, hawthorn, rose, honeysuckle, tartary buckwheat tea, chestnut, ilibiscus, lily,-hance, spikenard,banksia rose, sandalwood, agarwood, coffee, blueberry, and strawberry, the Chinese medicine raw material can be a combination of one or more of radix rehmanniae, preparedroot,cassia seed, dandelion,jujube, medlar,borneol, menthol, saffron, poria,holy basil,leaves,root,ginseng, white peony,andand the aerosol-generating raw material is made by grinding into powder and mixing.

In some embodiments, the aerosol-generating agent is glycerol, and the aerosol-generating raw material has the effect of locking water and promoting to produce a smokeable aerosol.

In some embodiments, the paste stick HNB aerosol-generating article is a density of 0.5 g-1.5 g/ml and a dynamic viscosity of 150-500 Pa.s, which is in a fluid form for being used to be injected into the HNB cartridge tube.
