技术领域technical field
本实用新型涉及一种电加热型卷烟烟具。The utility model relates to an electric heating cigarette smoking set.
背景技术Background technique
电加热型卷烟因其加热的温度不超过500℃，可显著减少卷烟中有害成分的释放和对环境的烟气危害，烟草行业已全面开展新型卷烟研究工作。多篇现有技术文献公开了电加热卷烟技术，通过加热但不燃烧的形式使烟草制品发烟，在满足消费者感官需求的同时减少烟草在高温环境下裂解出的有害成分。Because the heating temperature of electrically heated cigarettes does not exceed 500°C, it can significantly reduce the release of harmful components in cigarettes and the smoke hazards to the environment. The tobacco industry has comprehensively carried out research on new types of cigarettes. Many prior art documents disclose electric heating cigarette technology, which makes tobacco products smoke by heating but not burning, and reduces the harmful components cracked by tobacco in high temperature environment while satisfying consumers' sensory needs.
现有技术的电加热卷烟烟具典型地包含加热腔体、电加热元件、控制电路和电源。当发烟制品置入加热腔体，控制电路控制电加热元件电源的接通，加热元件迅速发热，使发烟制品迅速升温至发烟温度。在此过程中，加热温度仅通过控制电源接通时间进行控制，存在如下缺陷：The electric heating cigarette smoking set in the prior art typically includes a heating cavity, an electric heating element, a control circuit and a power supply. When the smoking product is put into the heating cavity, the control circuit controls the power supply of the electric heating element to be turned on, and the heating element heats up rapidly, so that the smoking product rapidly heats up to the smoking temperature. In this process, the heating temperature is only controlled by controlling the power on time, which has the following defects:
a.仅由电源接通时间控制加热温度，无法知道加热元件的准确温度，加热温度控制不精确；a. The heating temperature is only controlled by the power-on time, and the accurate temperature of the heating element cannot be known, and the heating temperature control is not accurate;
b.由于环境温度或系统工作时间的影响，加热元件起始温度不一样，导致在相同的加热时间内，加热元件的最高温度不同，温度控制不一致；b. Due to the influence of ambient temperature or system working time, the initial temperature of the heating element is different, resulting in different maximum temperature of the heating element and inconsistent temperature control within the same heating time;
c.加热元件温度控制不够稳定，发烟制品加热不够或者加热过度，导致每次抽吸差异较大。c. The temperature control of the heating element is not stable enough, and the heating of the smoking product is not enough or overheated, resulting in a large difference between each puff.
针对上述问题，本实用新型提供一种精确控温的电加热型卷烟烟具。In view of the above problems, the utility model provides an electric heating cigarette smoking set with precise temperature control.
