Embodiment 1

[0038] A closed heat-not-burn cigarette, comprising a tobacco rod (1-1), a hollow smoke extraction cone (1-2), a smoke transmission pipe (1-3), a functional filter (1-4) and an outer Coil material (1-5). Among them, the tobacco rod (1-1), the hollow smoke extraction cone (1-2), the smoke transmission pipe (1-3), and the functional filter tip (1-4) are sequentially contacted, and are wound by the external material ( 1-5) Parcel. (Such as Figure 4 shown)

[0039] The circumference and / or upstream end surface of the tobacco rod (1-1) is wrapped with an airtight or controllable air permeability paper-based or foil-based material to form a closed system.

[0040] The hollow flue gas extraction cone (1-2) includes a cylindrical base (1-2-1) and a tapered cone (1-2-2), and has a tapered cavity (1- 2-3) (such as image 3 shown); the taper cone (1-2-2) has a conical hole (1-2-2-1) on the cone top and / or side wall (as image 3 , Figure 5 , Figure 6 and Figure 9 shown).

Embodiment 2

[0049] A sealed heat-not-burn cigarette assembly, comprising the above-mentioned sealed heat-not-burn cigarette and a sealed heat-not-burn cigarette set (2).

[0050] The closed heating smoking appliance (2) includes a heating section (2-1), and the heating section (2-1) includes a cigarette accommodating cavity (2-1-1). (Such as Figure 7 , Figure 8 shown)

[0051] A heating element (2-1-2) is provided on the circumferential side wall and / or bottom surface of the cigarette accommodating cavity (2-1-1) (such as Figure 7 As shown), when the sealed heat-not-burn cigarette is inserted, it wraps the tobacco rod completely in the circumferential direction.

[0052] The airtight heating smoking appliance (2) further includes a cap (2-3), and the cap (2-3) and the heating segment (2-1) are directly and detachably connected to each other or through a sealing ring (2- 2) To achieve detachable connection, the cap (2-3) has a gradually expanding inner cavity (2-3-1). (Such as Fi...

Embodiment 3

[0058] The method of use of the present invention is as figure 1 , figure 2 As shown, the specific process is as follows: First, remove the cap of the heating device, insert a closed heat-not-burn cigarette, then replace the cap and lock it, and start heating while locking the cap. When inhaling, the air first enters the space between the cap and the cigarette, and then enters the inside of the smoke delivery tube through the through hole on the smoke delivery tube of the closed heat-not-burn cigarette and sprays to the surface of the extraction cone. Due to the Venturi effect and The Coanda effect will form a negative pressure at the cone hole; the heating of the tobacco rod will form a positive pressure on the tobacco rod; the existence of positive and negative pressure difference and smoke concentration difference will lead to the active diffusion of smoke, so the smoke It flows out from the cone hole and enters the oral cavity through the lumen of the smoke transmission ...

Abstract

The invention relates to a closed heating non-combustible cigarette and assembly, which comprises a closed heating non-combustible cigarette and a heating smoking set, the closed heating non-combustible cigarette is inserted into the heating smoking set to be heated and smoked when in use, and the closed heating non-combustible cigarette is characterized by comprising a tobacco rod, a hollow smoke extraction cone, a smoke transmission pipe and a filter tip, wherein all the parts sequentially abut against one another and are wrapped by an external rolling material, at least one through hole is formed in the side wall of the flue gas conveying pipe, and the through hole penetrates through the external rolling material; the heating smoking set comprises a heating section, a cover cap and a sealing ring, a cigarette containing cavity and a heating element are arranged in the heating section, and an inner cavity of the cover cap is of a divergent structure. The product has the advantages that air does not flow through the tobacco section, the oxygen content of the tobacco section can be reduced, and the heating temperature is greatly increased; a closed structure is adopted, tobacco residues cannot fall off, and smoking sets do not need to be cleaned frequently; the aroma components in the tobaccos are released more sufficiently and are easy to release continuously, the taste is closer to that of traditional tobaccos, and the tobaccos are easier to accept by traditional smokers.

Description

technical field [0001] The invention belongs to the field of heat-not-burn tobacco products, and in particular relates to a closed heat-not-burn cigarette and its components. Background technique [0002] Traditional tobacco has a history of hundreds of years and has been integrated into the lives of most smokers. In recent years, with the improvement of people's living standards, people have paid more and more attention to issues such as smoking and health, and the hazards of second-hand smoke, and the harmfulness of traditional tobacco products has become increasingly prominent. At the same time, with the implementation of the WHO Framework Convention on Tobacco Control, especially the gradual expansion of the scope of smoking bans in public places around the world, the development environment of tobacco products has undergone major and profound changes, and the structure of tobacco products is moving towards diversification. And the development direction of smoke-free to...
