Description

Cigarette with improved taste

Technical Field

The invention relates to the technical field of tobacco, in particular to a cigarette.

Background

As a healthier and more modern innovative product, a new type of tobacco product represented by a cigarette of the heat non-combustion type has rapidly started to rise around the world in recent years, and has attracted more and more consumers. Because the heating mode is different from the traditional cigarette product, the heating cigarette product can provide healthier smoking experience while meeting the sensory requirements of consumers on the cigarette product.

The cigarette structure is one of the core subjects in the field of heating and non-combustion. Under the condition of heating rather than combustion, the tobacco smoking section generates smoke and provides inherent fragrance of cigarettes, and then the filter section is matched with the tobacco smoking section to complete adsorption and filtration of large particles in the smoke.

The filter stick of the existing heating cigarette is usually made of acetate fiber tows, and in the process of intercepting and adsorbing harmful substances in smoke, tobacco flavor particles are adsorbed and diluted along with the filter stick due to the strong adsorption effect of the acetate fiber, so that the cigarette is not full enough in flavor; meanwhile, the existing filter stick has low cooling efficiency and high smoke temperature, so that the smoke temperature of the cigarette is hot and has an irritating feeling.

Therefore, a cooling filter stick capable of effectively reducing the temperature of the smoke of the heated cigarette and improving the flavor and taste of the smoke is urgently needed at present.
