The invention relates to a cigarette which is characterized in that the flow direction of smoke in the cigarette is from upstream to downstream.
The principle of the invention is as follows:
the Venturi effect, namely the phenomenon that the flow velocity of the fluid is increased when the fluid passes through the reduced flow cross section, is utilized, and the flow velocity is inversely proportional to the flow cross section area. While an increase in flow rate is accompanied by a decrease in fluid pressure, as is known from bernoulli's law. The invention provides a related structure by utilizing the principle that the flow velocity is increased and the temperature is reduced when gas enters a narrow channel from a wide channel.
Upon smoking, the tobacco section 3 is combusted or cured and the smoke stream flows from the cigarettes upstream and downstream to the cooling section 2. The fourth conical cavity 2a in the cooling section 2 can increase the flow speed of the flue gas and reduce the temperature by a structure with a narrowed width, so that the flue gas is cooled and rapidly enters the first conical cavity 1a in the filter section 1.
When the flue gas enters the first conical cavity 1a, the temperature of the flue gas is reduced and the flue gas rapidly flows out due to the principle that the cooling material and the same throttling surface are gradually reduced. At the moment, the second annular conical cavity 1b sucks air from the outside of the cigarette to enter the cavity due to the reason that the throttling surface is gradually reduced, and the air enters the first conical cavity 1a through the air holes 1d, so that the air flow of the first conical cavity 1a is increased, and the smoke temperature in the first conical cavity 1a is reduced, so that the purposes of increasing the smoke volume and reducing the smoke temperature during smoking are achieved.
And the third annular conical cavity 1c at the outermost part of the filter section 1 is mainly used for draining the flue gas in the fifth annular conical cavity 2b at the periphery of the cooling section 1, and the temperature of the drained flue gas is gradually reduced through the Venturi effect and the temperature reducing materials in the two annular conical cavities.
Therefore, the edge temperature of the tipping paper is reduced due to the design of the fifth annular conical cavity 2b and the third annular conical cavity 1c at the outermost periphery, the situation of mouth burning during suction is avoided, and good suction experience is achieved.
The invention has the following beneficial effects:
the invention designs a cigarette capable of promoting airflow to discharge for the first time, wherein a filter tip section and a cooling section in the cigarette are provided with a plurality of conical cavities, and the scheme of utilizing multiple Venturi effects, cooling materials, introducing external air and the like can accelerate the flow of smoke into the oral cavity of a user, reduce the resistance during suction, reduce the temperature of the smoke and increase the smoke quantity. Particularly, due to the existence of the fifth annular conical cavity 2b and the third annular conical cavity 1c on the outermost periphery, the temperature of the edge of the close tipping paper is reduced, the situation of mouth burning during suction is avoided, and good suction experience is achieved.
