Description

Outer cigarette cup locking type electric heating smoking set and electric heating assembly

Technical Field

The utility model belongs to the technical field of the heating smoking set, in particular to outer cigarette cup locking formula electrical heating smoking set and electrical heating component.

Background

A plurality of electric heating smoking systems are already proposed in the field of novel heating non-combustible cigarettes, and the harmful ingredients generated by the combustion of tobacco in the traditional cigarettes can be greatly reduced by using the electric heating smoking system containing the electric heater to heat the novel heating non-combustible cigarettes. However, the heating temperature provided by the electric heating smoking system is much lower than the temperature of the traditional cigarette during combustion, and compared with the traditional cigarette, the tobacco aroma components in the novel cigarette are difficult to completely release, and the smoke volume is small, so that the cigarette is difficult to be accepted by traditional smokers.

One means of increasing the release of the aroma components is to increase the heater temperature appropriately, but one factor limiting the heater temperature is that excessive temperatures can cause smoldering of the tobacco material, which can also produce harmful gases. In view of the three elements of combustion, the oxygen content of the air in which the tobacco material is located can be reduced if the temperature of the heater is to be increased further on the present basis.

One possible solution is to seal the space in which the tobacco material is located so that the air flow during smoking does not pass through the tobacco material. However, if the end of the rod is sealed, it is necessary to modify existing cigarette production lines, which substantially increases the production costs of the rod and limits the choice of heating means, for example the use of a central heating element.

In order to solve the above problems, the present invention is provided.
