Air heating structure with micro-spiral airflow channel and electronic cigarette

Abstract

The invention belongs to the related technical field of heat-not-burn electronic cigarettes and discloses an air heating structure with a micro-spiral airflow channel and an electronic cigarette. The air heating structure is suitable for the heat-not-burn electronic cigarette and comprises a heating body, wherein the heating body is a regular body, the heating body comprises an upper surface and a lower surface which are opposite to each other, and a first side surface and a second side surface which are respectively connected with the upper surface and the lower surface, and the first side surface and the second side surface are respectively used for connecting an electrode plate or another heating body; a winding micro-spiral airflow channel is formed in the heating body, the micro-spiral airflow channel penetrates through an upper surface and a lower surface and is used for allowing airflow to pass through, and the airflow is heated to a preset temperature when flowing through the micro-spiral airflow channel. Due to the fact that the heating time of the airflow is prolonged, the airflow is fully heated in the flowing process, and the heating structure has advantages of being high in heating efficiency, easy to machine, compact in size and long in service life.

Description

technical field [0001] The invention belongs to the related technical field of heat-not-burn electronic cigarettes, and more specifically relates to an air heating structure with a micro-spiral airflow channel and an electronic cigarette. Background technique [0002] The heat-not-burn electronic cigarette is a tobacco product that simulates a cigarette. It uses a battery connected to a heating element to heat a new type of tobacco at a relatively low temperature to release smoke to achieve the effect of a cigarette. Due to the lower heating temperature, the release of harmful substances such as tar is less, which is less harmful to the smoker, and the release of surrounding smoke is also smaller. [0003] The heating of heat-not-burn electronic cigarettes is usually done by ceramic heating elements or electric heating wires, usually in two ways: direct contact heating and indirect contact heating. Direct contact heating directly contacts the heating element with the shredd...

AI Technical Summary

Problems solved by technology

Direct contact heating directly contacts the heating element with the shredded tobacco. The heating efficiency is high, but it is easy to cause local scorching. At the same time, impurities are easily attached to the heating element, which reduces the heat transfer effect and needs to be cleaned up

[0004] Non-direct contact heaters usually heat the air first, and then the air heats the tobacco, which avoids the problem of troublesome cleaning of the heating element. However, due to the low temperature of the outside air, it is difficult to heat to the specified temperature range, and it is easy to cause uneven heating and The problem of slow smoke output and low heat utilization efficiency
