Problems solved by technology

The existing technology usually achieves the purpose of reducing the temperature of the filter tip by adding phase change materials in the filter rod, which will affect the sensory quality of cigarettes to a certain extent
In addition, if the cigarette filter has been kept well ventilated, for example, there is a large ventilation in the early stage of smoking, which will greatly affect the taste of smoking

Abstract

The invention belongs to the technical field of cigarette filters and particularly discloses a cigarette filter with a function of automatically adjusting and controlling the ventilation rate. The cigarette filter comprises a filter stick, formation paper wrapping the filter stick and tipping paper wrapping the surface of the formation paper; the tipping paper is provided with a ventilation area,and the ventilation area is provided with multiple ventilation holes; a phase change material layer for sealing the ventilation holes is arranged between the ventilation area and the formation paper.The invention further discloses preparation and application of the cigarette filter. According to the cigarette filter, ventilation of the cigarette filter is automatically adjusted and controlled along with the smoking progress of a cigarette, that is to say, the ventilation rate of the cigarette filter is zero in the initial smoking stage of the cigarette, and ventilation of the cigarette filteris achieved only 2-3 times before smoking ending; the aim of reducing harm and tar in cigarette smoke is achieved, the smoke temperature and concentration are lowered in the smoking process of 2-3 times, the ignition feeling is eliminated, and the consistency and stability of the smoking style of the whole cigarette are achieved.

Description

technical field [0001] The invention belongs to the field of cigarette filter design and processing, and in particular relates to a cigarette filter material. Background technique [0002] Cigarette filters have become an important medium for cigarette tar reduction and harm reduction. A lot of fruitful research work has been carried out on the materials and structures of cigarette filters inside and outside the industry. Cigarette filters mainly achieve the interception and filtration of harmful components in smoke through direct interception, inertial collision and diffusion deposition of aerosol particles. This is not only closely related to the physical properties and structure of the filter, but also closely related to the temperature distribution of the cigarette filter. relevant. During the 5-7 puffs of the cigarette, the smoke concentration and smoke temperature increase, and the concentration of the total material phase and harmful substances in the smoke is signif...
