Disposable double-channel cigarette and preparation method thereof

Abstract

The invention discloses a disposable double-channel cigarette. The disposable double-channel cigarette comprises a tobacco unit, a heat source unit and a filtering unit; the tobacco unit includes a tobacco unit channel (1), a smoking end and an ignition end, the heat source unit includes a heat source unit channel (2), and the filtering unit includes a filtering unit channel (7) and is arranged atthe smoking end of the tobacco unit; and the tobacco unit channel (1) and the heat source unit channel (2) are internally provided with pneumatic devices (3), gas suction devices (4) and linkage devices. The invention further discloses a preparation method of the cigarette. According to the disposable double-channel cigarette, through the pneumatic devices and the linkage devices, heat can be supplied by matching with the puff-by-puff smoking habit; and additionally, tobacco and a heat source have the mutually-independent and parallelly-formed gas flow channels correspondingly, and harmful substances generated during fuel burning are completely prevented from being ingested by the body of a smoker.

Description

technical field [0001] The invention belongs to the field of cigarettes, in particular to a disposable double-channel cigarette and a preparation method thereof. Background technique [0002] After long-term exploration and conclusion, it is found that tobacco products, as a daily consumption hobby commodity, must have the following three characteristics in order to succeed in the market and satisfy the core consumption experience: mouth-by-mouth smoking and one-time consumption , Smoking safety. Among them, puff-by-puff is adapted to the way people breathe; one-time consumption is because the daily consumption of cigarettes is mainly for convenience; smoking safety is the minimum requirement for it as a food. Products that cannot properly satisfy the above three characteristics will be difficult to succeed in the market. [0003] In the traditional field, traditional tobacco products refer to burn-and-suck tobacco products that use the chemical energy provided by tobacco ...

AI Technical Summary

Problems solved by technology

Although the two problems of mouth-by-mouth suction and smoking safety have been better solved, such as the content recorded in the Chinese patent "Heated Aerosol Generating Device and Method for Generating Aerosol with Consistent Characteristics" patent application number CN2017108122320 , but it introduces other serious problems: First, it is very inconvenient to carry special cigarettes and electric heaters at the same time; second, because the battery in the electric heater needs to be charged repeatedly, it is inconvenient to use and cannot be used Disposable consumer use; thirdly, and most importantly, the battery itself has great potential safety hazards, and the explosion of the supporting battery of electric heating tobacco products has caused the users to suffer serious personal injuries. Real cases have appeared and have been reported ; Fourth, because scrapped batteries need special treatment, not only will additional disposal costs be incurred, but batteries that are not disposed of properly will also cause serious pollution to the environment, leading to increased pressure on environmental protection

In summary, all new tobacco products that require the use of batteries have serious technical defects and should be abandoned or eliminated

[0010] 2. The fuel-heated tobacco products produced by the existing technology are different from the electric-heated tobacco products. Although they have good basic conditions for one-time consumption and use, there are major technical problems in smoking safety and puff-by-puff. defect

Its technical flaws are: first, the fuel is burned in a smoldering manner, with low calorific value and poor effect, and thus produces more incomplete combustion products, such as easy flameout and low heating efficiency; second, after ignition The fuel burns continuously on its own, which cannot meet the actual situation of changing peak heat demand during puff-by-puff, resulting in poor heating effect of tobacco, poor taste and quality of smoking, and obvious fuel waste

In response to this problem, the patent "A Heat-Not-Burn Tobacco Suction Device Based on a Mechanical Energy Storage Type Air Suction Component" patent application number CN201810982289X discloses a solution to promote air flow by using a clockwork spring to drive a fan. The fuel provides heat through complete combustion as much as possible, but this invention still has significant technical defects: first, because the components such as clockwork-driven fans and heat transfer elements are expensive, this invention is used for repeated use, and not a one-time consumption

Due to its design principle, it has significant technical defects: First, whether it is a physical or chemical reaction, it may cause a reaction or even an explosion due to high temperature or collision or drop during transportation.

Secondly, the chemical reaction of the physical and chemical reaction heating tobacco products also has the safety problem that the exhaust gas may directly enter the smoker's mouth due to the smoker's suction action

Third, similarly, once the physical and chemical reactions are started, they will continue to occur until the end of the reaction, and cannot provide heat peak changes in order to match the rhythm and method of puffing.

If a solution is to be sought under the existing technical conditions, then consumers can only purchase two products of traditional tobacco products and new tobacco products for consumption, which greatly increases the consumption cost of consumers

[0014] 5. At present, many countries or regions that allow the sale of traditional tobacco products restrict the sale of heat-not-burn cigarettes due to policies and other reasons
