Abstract
A kind of one-time heating is not burnt cigarette, it is characterised in that：Filter segment, tobacco segment and fuel section including passing sequentially through cigarette paper connection, indwelling has the gap of 1 5mm between tobacco segment and fuel section, tobacco segment section core is equipped with a hollow cavity vertically, the length of hollow cavity is not less than the 10% of tobacco segment length, and hollow cavity is communicated with gap, the fuel section is the carbonaceous heat-source rod with ventilative duct.The cross-sectional area of hollow cavity is the 5 50% of tobacco segment cross-sectional area, the utility model improves heat in conventional carbon heating cigarette and enters the inhomogeneities heated to nearly mouth end tobacco-containing material from tobacco segment bottom, hollow structure in the gap being arranged between tobacco segment and fuel section and tobacco segment, it can preferably be lifted and heat the not sucking quality of burning type cigarette and improve the utilization rate of nearly mouth end tobacco-containing material, there is higher application value.
Description
Technical field：
It the utility model is related to and heat the cigarette that do not burn, particularly a kind of one-time heating non-combustion-type cigarette.
Background technology：
Burning type cigarette is not heated generally by the air that carbon material burning convective passes through for carbon heating at present, to follow-up
The tobacco-containing material contacted carries out heating destructive distillation and provides flue gas.Existing patented technology：" it is applied to non-burning smoking product
Carbonaceous heat source forms "（Application number 07741016.5, publication number EP2018813A1）And article " Exposure evaluation
of adult male Japanese smokers switched to a heated cigarette in a controlled
clinical setting”（Regulatory Toxicology and Pharmacology.2014,69 (3):338-347.）
Disclose a kind of non-burning cigarette of carbon hot type.Prior art carbon hot type cigarette, generally existing is empty in actual aspiration procedure
Temperature degree rapid decrement with the length of tobacco column, the problems such as thereby reducing the utilization rate of nearly mouth end tobacco-containing material, suction
Experience sense needs to be further improved.
The content of the invention：
The purpose of this utility model is exactly to heat not burning type cigarette the deficiencies in the prior art for current carbon and provide
A kind of one-time heating non-combustion-type cigarette.This cigarette compared with prior art, due to the improvement of gas channel, tobacco-containing material
Utilization rate be greatly improved.
The present invention is achieved through the following technical solutions：A kind of one-time heating is not burnt cigarette, including passes sequentially through volume
Cigarette paper connection filter segment, tobacco segment and fuel section, between tobacco segment and fuel section indwelling have the gap of 1-5mm, tobacco segment
Section core is equipped with a hollow cavity vertically, and the length of hollow cavity is not less than the 10% of tobacco segment length, and hollow cavity and gap phase
Logical, the fuel section is the carbonaceous heat-source rod with ventilative duct.
In the utility model, the cross-sectional area of the hollow cavity is the 5-50% of tobacco segment cross-sectional area；The length of hollow cavity
Degree is preferably the 50-90% of tobacco segment length.
The carbonaceous heat-source rod can be carbon rod, or the heat-source rod being made of Chinese mugwort class material.
Heat-insulating flame-retardant layer is equipped with outside tobacco segment and gap section, in order to which hand-held and insulation, heat-insulating flame-retardant layer wrap on a small quantity
Wrap up in heat source section（That is heat source section extends a small distance）, support is risen to heat source and is drawn after preventing heat source all burnt with cigarette paper
Fire tobacco rod.
In use, lighting carbonaceous heat source, the air stream flowed through is heated by aspirating, then by hollow structure stream
It is heated through tobacco-containing material, is sucked for consumer.When carbon heat source burns to gap, carbonaceous can be played by gently touching
Heat source is shaken with heat-insulating flame-retardant layer contact portion, avoids the burning of tobacco forage.
Cigarette structure designed by the utility model can by through the air that heat source heats from tobacco rod bottom and axle center at the same time
Heating distillation is carried out to tobacco-containing material, avoids and nearly mouth end tobacco-containing material is utilized caused by successively decreasing in the prior art due to heat
The problem of rate is low, also improves heat in conventional carbon heating cigarette and enters from tobacco segment bottom to the heating of nearly mouth end tobacco-containing material
Inhomogeneities, the hollow structure in the gap being arranged between tobacco segment and fuel section and tobacco segment, can preferably be lifted plus
The sucking quality of hot not burning type cigarette, has higher application value.

Embodiment
The utility model is further described below in conjunction with attached drawing：
As shown in Figure 1：A kind of one-time heating is not burnt cigarette, including pass sequentially through the connection of cigarette paper 7 filter segment 3,
Tobacco segment 2 and fuel section, between tobacco segment 2 and fuel section 1 indwelling have the gap 6 of 1-5mm, tobacco segment core is equipped with vertically
One hollow cavity 5, the cross-sectional area of hollow cavity 5 are the 10-30% of 2 cross-sectional area of tobacco segment, and the length of hollow cavity 5 is grown for tobacco segment 2
The 70-90% of degree, and hollow cavity 5 is communicated with gap 6, the fuel section 1 is the carbonaceous heat-source rod with ventilative duct（It is preferred that charcoal
Rod）.
Heat-insulating flame-retardant layer 4 is equipped with outside tobacco segment and gap section, in order to hand-held and insulation and support heat source and is prevented
The only effect of tobacco rod burning.
