Description
Technical Field
The patent of the utility model relates to a heating cigarette production technical field, concretely relates to filter unit and contain its heating cigarette with flute structure.
Background
Along with the attention of consumers to health problems and the improvement of the demand of individualized experience of cigarette products, the tobacco industry continuously responds to the demand upgrade of consumers and develops various cigarettes with tar and harm reduction. The cigarette heating mode of the non-combustion type cigarette is different from that of the traditional cigarette product, so that the cigarette heating mode can meet the sensory requirements of consumers on the cigarette product and provide healthier smoking experience.
The existing heating cigarette mainly comprises a smoking unit, a hollow supporting section, a cooling section and a filtering unit, wherein the existing cooling section is mostly a gathered polylactic acid film, the adhesion is easy to occur between the existing cooling section and the existing cooling section after heat absorption, the smoking amount is reduced, the cooling effect is not ideal, and the temperature of the cigarette entering the oral cavity of a consumer is high. In addition, when the smoke passing through the cooling section passes through the filtering unit, part of the temperature of the smoke is transferred to the surface of the filter tip along with the heat transfer effect of the filtering material, so that the filter tip is directly too hot, and part of consumers think that the surface temperature of the heated cigarette filter stick is high and the filter tip is hot.
In order to further effectively reduce the temperature of the flue gas, on one hand, the using amount of a cooling material at the cooling section is increased, but the method only can slightly improve the cooling effect, and the cost at the cooling section is greatly improved; on the other hand, air is introduced to increase ventilation, the hollow support section of the cigarette is generally perforated by adopting an online laser perforation method, the pipe wall of the hollow support section, forming paper and tipping paper wrapping the hollow support section are perforated to form a vent hole, and air is introduced, but the amount of air introduced by the method is limited, the cooling effect is not obviously improved, more importantly, the online laser perforation process has higher requirements on the material and the thickness of the pipe wall of the hollow support section, firstly, the material of the pipe wall of the hollow support section cannot collapse in the online laser perforation process, and the pipe wall of the hollow support section cannot be particularly thick, so that the cigarette cannot be perforated during online laser perforation; the requirement of the online laser drilling process on laser power is very high, and if the laser drilling equipment fails to drill the wall of the hollow supporting section pipe, the problems of unqualified production of the heated cigarette and overheating of the smoke temperature can occur.
It would therefore be desirable to produce a heated cigarette rod having a filter element surface that does not burn the mouth and a suitable smoke temperature entering the mouth of the consumer.
The present invention is proposed in order to solve the above problems.
