Sidewall-punctured heated tobacco product

Abstract

A sidewall-punctured heated tobacco product ( 9 ), comprising a tobacco section ( 1 ) and a functional mouthpiece rod section ( 3 ). A vapor extraction section ( 2 ) is provided between the tobacco section ( 1 ) and the functional mouthpiece rod section ( 3 ). The tobacco section ( 1 ), the vapor extraction section ( 2 ), and the functional mouthpiece rod section ( 3 ) are wrapped and connected together by means of external wrapping and tipping materials. The vapor extraction section ( 2 ) is a cylinder comprising a hollow structure ( 2 - 1 ), and at least one sidewall through hole ( 2 - 2 ) communicated with the hollow structure ( 2 - 1 ) is formed on the sidewall of the cylinder. In use, the tobacco product ( 9 ) is inserted into a closed heating smoking set, and during vaping, vapor generated by the tobacco section ( 1 ) is mixed, after active migration, with air entering from the sidewall through hole ( 2 - 2 ) to form mainstream vapor. The tobacco product ( 9 ) can conveniently adjust the extraction efficiency, dilution rate, and temperature of vapor, thereby improving the organoleptic qualities of the heated tobacco product ( 9 ), and can effectively prevent cold air from passing through the tobacco section ( 1 ) during a vaping process, thus improving the heating efficiency, and effectively reducing the content of oxygen of the tobacco section ( 1 ) to achieve a heat-not-burn purpose. In addition, the tobacco product ( 9 ) is simple in structure and easy for industrial production.
