Description

The invention relates to tobacco technology, in particular to a draw resistance adjuster and an electronic cigarette cartridge including the draw resistance adjuster.

According to, in recent years, consumers have paid more and more attention to health issues and demand for personalized experience of cigarette products. The tobacco industry has continuously responded to the upgrading of consumer demand and developed various cigarettes with reduced tar and harm. Among them, heat-not-burn electronic cigarettes can provide a healthier smoking experience while satisfying consumers' sensory needs for cigarette products because their cigarettes are heated in a different way than traditional cigarette products.

Existing heat-not-burn e-cigarette pods mainly include a smoking base section, a hollow support element, a hollow section, a filter tip and a wrapping piece. Assist the cooling section to cool down the flue gas. In the prior art, ventilation holes are formed by piercing the tube wall of the hollow support element, so that the outside air enters the hollow support element and mixes with the smoke aerosol, thereby increasing the amount of smoke and effectively reducing the temperature of the smoke aerosol, but its influence on the smoke aerosol The cooling effect and the mixing effect of air and smoke aerosol are still not good, and the suction resistance increases in the later stage of combustion.

The reason lies in the following two points: 1. The contact area between the flue gas aerosol and the tube wall of the hollow support element is limited, and effective cooling cannot be achieved; 2. When the formation matrix of the flue gas aerosol is particles, the ventilation form of the hole is very easy to form an airway Blockage will lead to increased suction resistance, which will affect the suction experience, and the airway will not circulate smoothly. In severe cases, the smoking matrix will be continuously heated due to airway blockage, resulting in a reduction in the intake of external cold air, resulting in burnt air. Situation; 3. The airflow path of the smoke aerosol and air in the hollow support element is a straight line, and the residence time in the hollow support element is short. The smoke aerosol and air directly and quickly enter the hollow section through the hollow support element, and cannot achieve sufficient mixing .

Therefore, it is necessary to develop a technology to increase the area and length of the smoke aerosol channel, assist in cooling down, and at the same time take into account the support effect that is not easy to block, effectively reduce the suction resistance, and achieve a good suction experience.
