Multi-section temperature control method, multi-section heating equipment and computer readable storage medium

Abstract

The invention provides a multi-section temperature control method and multi-section heating equipment. The temperature control method is used for controlling the heating process of the multi-section heating equipment, the multi-section heating equipment comprises a heating cavity and a plurality of heating elements which are sequentially arranged from top to bottom, and the heating element at theuppermost end is a first heating element; the temperature control method comprises steps that the heating process of each heating element independently comprises three stages, and in the first stage,the heating elements are heated from the initial temperature to the first target temperature; in the second stage, the heating element maintains the first target temperature; in the third stage, the heating element is cooled from the first target temperature to the second target temperature, and the start time and the end time of the second stage of the heating element below are later than the start time and the end time of the second stage of the heating element above respectively; and the first target temperature of the first heating element is lower than the first target temperatures of theother heating elements. The invention further discloses a computer readable storage medium.

Description

technical field [0001] The invention relates to the technical field of tobacco, in particular to a multi-stage temperature control method, multi-stage heating equipment and a computer-readable storage medium. Background technique [0002] In recent years, as people pay more and more attention to health, people realize that traditional cigarettes are harmful to health, and the impact of traditional cigarettes on health and environment has gradually attracted the attention of countries all over the world. Tobacco manufacturers are committed to providing consumers with less harmful tobacco products. In recent years, heat-not-burn smoking devices, as a new form of tobacco consumption, have gradually been welcomed by the market and are increasingly accepted by cigarette consumers in most countries. [0003] Since the heat-not-burn smoking set IQOS was launched in 2015, heat-not-burn smoking sets have emerged in an endless stream. Many foreign and domestic companies have launched ...

AI Technical Summary

Problems solved by technology

However, limited by the size of the heat-not-burn smoking appliance, the power and output power of the battery of the heat-not-burn smoking appliance are not enough to provide high heat that can heat the entire smoking unit at the same time, and segmental heating is required to reduce the requirements on the battery

[0004] In the prior art, a variety of segmented heating smoking appliances for specially configured heat-not-burn cigarettes are disclosed, such as reference 1 (WO2019173938A1) and reference 2 (WO2020181518A1), but the smoking appliances in these patents are designed for heat-not-burn Cigarette design, because there is no reasonable heating temperature curve specially designed for traditional cigarettes, it will cause problems such as low tobacco utilization rate, slow smoke response speed, and uneven smoke volume per puff.
