Embodiment 1

[0038] Such as figure 1 As shown, the heating element for low-temperature cigarettes includes a heating body 2 arranged along the length direction of the tobacco part 101 of the cigarette 1. The heating body 2 is composed of a first heating section 201 corresponding to the air intake section of the tobacco part 101 and corresponding to the middle section of the tobacco part 101. The second heating section 202 and the third heating section 203 corresponding to the air outlet section of the tobacco part 101 are sequentially connected; along the length direction of the tobacco part 101, the heating power of the second heating section 202 to the unit volume of tobacco is P.

[0039] The heating power of the first heating section 201 to a unit volume of tobacco is (3-8)P, preferably (3-4)P, more preferably 3P.

[0040] The heating power of the third heating section 203 to a unit volume of tobacco is (1.5~4)P, preferably (2~3)P, more preferably 2P.

[0041] The length of the first ...

Embodiment 2

[0045] Such as figure 2 As shown, in Embodiment 2, the heating element for low-temperature cigarettes includes a heating body 2 arranged along the length direction of the tobacco part 101 of the cigarette 1, and the heating body 2 is composed of a first heating section 201 corresponding to the air intake section of the tobacco part 101, and a The second heating section 202 corresponding to the middle section of the tobacco part 101, and the third heating section 203 corresponding to the outlet section of the tobacco part 101 are sequentially connected; along the length direction of the tobacco part 101, the thermal power of the second heating section 202 to the unit volume of tobacco for P.

[0046] The heating power of the first heating section 201 to a unit volume of tobacco is (3-8)P, preferably (3-4)P, more preferably 3P.

[0047] The heating power of the third heating section 203 to a unit volume of tobacco is (1.5~4)P, preferably (2~3)P, more preferably 2P.

Abstract

The invention discloses a heating element for a low-temperature cigarette and the low-temperature cigarette. The heating element for the low-temperature cigarette comprises a heating body, and the heating body is formed by sequentially connecting a first heating section corresponding to a tobacco part gas inlet section, a second heating section corresponding to a tobacco part middle section and athird heating section corresponding to a tobacco part gas outlet section; in the length direction of a tobacco part, the thermal power of the second heating section to tobacco per unit volume is P, the thermal power of the first heating section to the tobacco per unit volume is (3-8)P, and the thermal power of the third heating section to the tobacco per unit volume is (1.5-4)P. According to the heating element, for the characteristic that the demands of smoke generated by heating various sections of the tobacco part of each cigarette for heat are different, segmented design is adopted for thethermal power and length of the heating body, the atomization smoke outlet speed is high, the tobacco part is not easily carbonized or burnt, the smoke taste is good in consistency, and the user experience is good.

Description

technical field [0001] The invention particularly relates to a heating element for low-temperature cigarettes and the low-temperature cigarettes. Background technique [0002] At present, in various low-temperature cigarettes, the tobacco portion of the cigarette is heated by a heating element to generate smoke for the user to smoke. In the prior art, along the length direction of the tobacco part, the heating power of each section of the heating element is the same. Since the air intake section of the tobacco section is continuously supplied with cold air, part of the heat of the heating element corresponding to the intake section of the tobacco section is used to heat the cold air; the part of the heating element corresponding to the middle section of the tobacco section and the air outlet section of the tobacco section is only used for heating Tobacco without heating the cold air. Therefore, it is easy to have a long waiting time for the smoke or local carbonization and...
