Cigarette heating assembly and low-temperature smoking set

Abstract

The embodiment of the invention discloses a cigarette heating assembly and a low-temperature smoking set which are used for improving airflow distribution in a cigarette and enabling airflow distribution passing through the cigarette to be more uniform. The cigarette heating assembly provided by the embodiment of the invention comprises a cigarette heating cylinder which is provided with a first end and a second end which are opposite to each other; the first end is used for inserting a cigarette, and the second end is a closed end; an airflow groove extending from the first end to the second end is formed in the inner side wall of the cigarette heating cylinder; a plurality of shunting bosses are arranged on the inner bottom surface of the second end, and are uniformly distributed at intervals around the central point of the inner bottom surface in a circular ring shape; and an annular flow dividing air channel is formed between the flow dividing boss and the cigarette heating cylinder. The airflow groove and the side wall of a cigarette inserted into the cigarette heating cylinder in a matched mode define an air inlet channel communicating external air with the flow dividing air channel.

Description

technical field [0001] The invention belongs to the technical field of smoking articles, and in particular relates to a cigarette heating component and a low-temperature smoking article. Background technique [0002] Heat-not-burn electronic tobacco products are a new type of tobacco, which is heated by electric heating to reduce the release of harmful components. At present, the two mainstream heating methods are internal heating and external heating. Internal heating means using a heating needle or a heating sheet inserted into the tobacco of the cigarette for heating, while external heating means heating with a heating device surrounded by the outside of the cigarette. [0003] Previously, the applicant had used the method of opening a diversion channel in patents such as CN2019205072076 to realize the air entering the cigarette. The diversion channel was opened around the heating device and parallel to the axis of the cigarette. After entering the cigarette in the reve...

AI Technical Summary

Problems solved by technology

For external heating equipment that adopts diversion channels for air intake, if too many diversion channels are opened, the heat generated by the heater will be taken away, which will affect the normal heating of cigarettes

If there are too few diversion grooves, at the bottom end of the cigarette where the airflow turns, there will be serious unevenness after the airflow enters the cigarette, and it will appear more uniform after entering the cigarette for a certain distance, which will As a result, the section of tobacco is heated unevenly, which affects the release of tobacco components and the taste of the user, and is also not conducive to the heat dissipation of the equipment
