Description

Heating cigarette with non-through cavity filter stick

Technical Field

The utility model relates to a heating cigarette technical field especially relates to a heating cigarette with do not link up cavity filter rod.

Background

In recent years, electrically heated cigarettes (heated cigarettes) have been developed in the tobacco industry. The heated cigarette has a smoking material (otherwise known as a smoker, aerosol former). When the heating cigarette is put into the heating appliance, the heating appliance controls the heating element in the heating appliance to be switched on to generate heat, the heating element heats the smoking material in the heating cigarette, so that the smoking material is heated to the smoking temperature, and the smoking requirement of a user is met by generating smoke. The heated cigarette is closest to the traditional cigarette in the aspects of smoking mode, smoking experience and the like, and the release amount of harmful ingredients is less, so the heated cigarette has great development potential in the tobacco market.

The prior heating cigarette has the following problems:

1. the heating cigarette usually adopts a four-section type or five-section type structure, and the structure is complex, and the processing technology is complex.

2. The smoke temperature is higher and the smoking experience of consumers is poor. The tobacco material in a heated cigarette is typically heated in a heating appliance to a temperature of 250 c to 350 c, which allows for the efficient release of volatile chemicals. However, because the heated cigarette has a short length, the cigarette is in a high-temperature surrounding of a heating appliance, and the heat exchange rate is poor, the smoke temperature at the inlet end is too high, the burning feeling and the irritation are obviously increased, and the smoking experience of consumers is poor.

3. The smoke amount in the smoke is low, and the experience and satisfaction of consumers are poor. The smoke quantity is influenced by the suction resistance and the filtering efficiency of the filter stick when the heated cigarette is smoked. The existing heating cigarette has large suction resistance and high filtering efficiency, smoke is absorbed by a filter stick more, so that the smoke quantity is small, and the experience and satisfaction of consumers are poor.
