In heating by the heating rod, the heating rod (131) pierces the core portion of the tobacco segment (51) to heat, an air flow flows through the core portion of the tobacco segment (51), and the heating rod is the core portion of the tobacco segment (51). And step s6, which is provided with three types of heat transfer paths: conduction, radiation, and convection.
After heating the tobacco segment (51) in cooperation with heat conduction, heat radiation and convection heat transfer, the tobacco scent is released or volatilized, and the airflow entrains the tobacco scent and flows into the filter segment for filtration and cooling. Including step s7, which is performed and finally enters the smoker's oral cavity.
However, claim 1 is characterized in that steps s5 and s6 are steps parallel to steps s1 to s4, and the steps s4, s5 and s6 cooperate to complete omnidirectional uniform heating of the tobacco (5). A method for heating a cigarette using the uniform heating device according to the above. A method of heating a cigarette using the uniform heating device according to claim 1.
A seal ring (15) is provided at the right end of the heating assembly housing, between the cigarette (5) and the seal ring (15), and between the cigarette (5) and the right end opening of the smoking goods casing (3). A first intake port is formed, a second intake port is provided at the left end of the heating assembly housing, and a third intake port is provided in the gap between the right end of the heating cylinder (132) and the seal ring (15). Is formed, the tobacco (5) is inserted into the heating cylinder (132) from the right end, and the heating rod (131) is pierced into the tobacco segment (51) of the tobacco (5) to form the tobacco segment (51). There is a gap between the side wall and the bottom of the third heating chamber (C), and the filter segment of the cigarette (5) is pumped while turning on the power to heat the heating cylinder (132) and the heating rod (131). And the specific heating step is
The airflow enters the first heating chamber (A) through the first intake port, and the airflow flowing into the first heating chamber (A) orbits the outer surface of the heating assembly (1) and flows downward, and is preheated. Step s1 to complete and
The preheating airflow in the first heating chamber (A) enters the second heating chamber (B) through the second intake port, and the airflow orbits the outer surface of the heating cylinder (132) and flows upward, and further heating. Step s2 to complete
The airflow further heated in the second heating chamber (B) enters the third heating chamber (C) through the third intake port, and the side walls and the bottom of the tobacco segment (51) and the third heating chamber (C). Step s3, which flows downward through the gap and further heats the airflow,
In convection heating of the tobacco segment, the airflow flowing into the third heating chamber (C) orbits between the tobacco segment (51) and flows downward, flows in from the bottom of the tobacco segment (51), and permeates from the side surface. Step s4, in which the air flows into the tobacco segment (51) by a method and convection heating is completed for the tobacco segment (51),
In heat radiation by the heating sleeve, the heating cylinder (132) performs circumferential heat radiation on the circumference of the tobacco segment (51) arranged in its internal cavity, and step s5.
In heating by the heating rod, the heating rod (131) pierces the core portion of the tobacco segment (51) to heat, an air flow flows through the core portion of the tobacco segment (51), and the heating rod is the core portion of the tobacco segment (51). And step s6, which is provided with three types of heat transfer paths: conduction, radiation, and convection.
After heating the tobacco segment (51) in cooperation with heat conduction, heat radiation and convection heat transfer, the tobacco scent is released or volatilized, and the airflow entrains the tobacco scent and flows into the filter segment for filtration and cooling. Including step s7, which is performed and finally enters the smoker's oral cavity.
However, the step s5, s6 a step of parallel to step s1 to s4, the step s4, s5, and s6 are claimed in claim 1, wherein the completion of all rectangular position-uniform heating of the tobacco in conjunction A method of heating cigarettes using a uniform heating device.
