Heater for heat-not-burn cigarette

Abstract

The invention discloses a heater for a heat-not-burn cigarette, comprising: a shell, in which a cylinder with openings at two ends is arranged, and a gap is arranged between the outer wall of the cylinder and the inner wall of the shell; a heating part, wherein the top of the heating part is arranged outside the shell, and the bottom of the heating part penetrates through the top of the shell andis arranged inside the shell; a cigarette containing part, wherein the heating part is sleeved with the cigarette containing part, the bottom of the cigarette containing part is connected with the outer surface of the top of the body, and a first cavity is formed between the inner wall of the cigarette containing part and the outer wall of the heating part; an air suction channel which is arrangedin the gap, wherein the first end of the air suction channel is communicated with the outside, and the second end of the air suction channel is communicated with the first cavity; a combustion chamber which is arranged in the cylinder and comprises a fuel channel and a combustion-supporting air channel, wherein the first end of the fuel channel and the bottom end of the heating part are arrangedin a spaced mode, the second end of the fuel channel is communicated with the outside, and the two ends of the combustion-supporting air channel are both communicated with the outside; and a smoke exhaust channel which is arranged in the gap, wherein the first end of the smoke exhaust channel communicates with the interior of the cylinder, and the second end of the smoke exhaust channel communicates with the outside.

Description

technical field [0001] The invention relates to a heater for heating non-burning cigarettes, which belongs to the technical field of smoking utensils. Background technique [0002] The high-temperature hot combustion zone formed by traditional cigarettes during smoking will generate high-temperature airflow, which will cause the downstream tobacco dry distillation to produce volatile substances and form smoke, which contains nicotine and other harmful substances to the human body. Moreover, when the temperature is higher, the decomposition reaction of tobacco will produce tar and other harmful substances, which will seriously affect human health. With the continuous improvement of citizens' health awareness, the global tobacco control efforts are continuously intensified. To solve these problems, new types of tobacco have emerged, which mainly include heat-not-burn tobacco, electronic cigarettes and snus. The new type of tobacco reduces the release of harmful substances in...

Problems solved by technology

However, the working time of the electric heating method is short (generally only one short cigarette can be smoked on a single charge), so it is not suitable for people who work outdoors for a long time

[0004] In addition, in order to facilitate the suction of air into the cigarette, the existing heaters at home and abroad generally adopt the central rod heating method, and the sucked air enters from the surrounding of the heat-not-burn cigarette.

However, the existing central rod heating method has poor utilization of exhaust gas waste heat, high exhaust gas temperature, and long temperature rise time of the central rod
