Low-oxygen heating-type smoking set

Abstract

A low-oxygen heating-type cigarette assembly, comprising a low-oxygen heating-type smoking set (B) and a low-oxygen heating-type cigarette (A). The low-oxygen heating-type smoking set (B) comprises a heating section ( 4 ) and a smoke extracting member ( 2 ) detachably arranged with the heating section ( 4 ), wherein the heating section ( 4 ) is provided with a cigarette receiving chamber ( 4 - 1 ), and the smoke extracting member ( 2 ) comprises a hollow smoke extracting cone ( 2 - 1 ) and a smoke transmission tube ( 2 - 2 ). The low-oxygen heating-type cigarette (A) comprises a tobacco section ( 1 ) and a filter mouthpiece section ( 3 ) detachably connected to each other; during inhalation, the tobacco section ( 1 ) and the filter mouthpiece section ( 3 ) of the low-oxygen heating-type cigarette (A) are detached, and are respectively assembled with the smoke extracting member ( 2 ) to form a segmented cigarette; the tobacco section ( 1 ) of the segmented cigarette is inserted into the cigarette receiving chamber ( 4 - 1 ) to start up a heating element for smoking. The split-type cigarette design significantly simplifies the structure of the cigarette, keeps the tobacco section ( 1 ) in a low-oxygen environment, increases the heating temperature, prevents tobacco residue from falling out, and keeps the smoking set clean.
