Multi-stage temperature control method of heat-not-burn system

Abstract

The invention provides a multi-stage temperature control method for a heat-not-burn system. According to the method, a base plate is included, a third heating needle is arranged on the base plate, andheating modes of a first heating needle, a second heating needle and the third heating needle are controlled by a circuit board respectively; the first heating needle, the second heating needle, andthe third heating needle are inserted into a first section, a second section and a third section of a cigarette, and the first heating needle, the second heating needle, and the third heating needle heat the first section, the second section and the third section respectively and sequentially and then heat the cigarette together. The inside of the cigarette can be heated uniformly, the heat transfer is uniform, heat in the cigarette is in a balance state, and the defect is overcome that the local temperature is extremely high. The aromas from the cigarette can be fully volatilized, and the taste of smoking can be kept consistent and full with the fresh aromas at a time.

Description

technical field [0001] The invention relates to a multi-stage temperature control method of a heat-not-burn system. Background technique [0002] At present, an electronic cigarette is used, also known as an aerosol generating device. The difference from traditional cigarettes is that the electronic cigarette uses low-temperature heating without burning instead of manual ignition and baking, and does not need to carry an ignition device, which is more convenient for users to use. There are generally two heating methods for electronic cigarettes in the prior art: one is to adopt a central heating structure, because the heating needle is inserted into the center of the cigarette from below, and the heating needle generates heat, which spreads around the cigarette, but this This heating method diffuses slowly, and the heating efficiency is low. When smoking electronic cigarettes, it is easy to cause a small amount of smoke and poor taste effect. [0003] The other is periphera...

Problems solved by technology

There are generally two heating methods for electronic cigarettes in the prior art: one is to use a central heating structure, because the heating needle is inserted into the center of the cigarette from below, and the heating needle generates heat, which spreads around the cigarette, but this This heating method diffuses slowly, and the heating efficiency is low. When smoking electronic cigarettes, it is easy to cause a small amount of smoke and poor taste effect

[0003] The other is peripheral heating, inserting cigarettes into the heating chamber, setting heating wires on the inner or outer walls of the heating chamber, the heating wires generate heat, and the heat is transmitted inward through the outer wall of the cigarettes. The heating efficiency is high, and it is easy to cause excessive smoke when smoking electronic cigarettes. The heating efficiency is too high, which leads to a short smoking time per unit amount of shredded tobacco, which increases the smoking cost
