DETAILED DESCRIPTION OF THE INVENTION
(27) The following drawings and specific embodiments will describe the present invention in detail.
(28) For the terms used herein, cigarette consumable items refers to any filling material used in the smoking articles, particular the cigarettes, which can be either the conventional material, such as normal tobacco, nontobacco plant, signal or hybrid carbon fuel material, there is no limitation of materials in this invention, and there is no limitation of manufacture process and supporting materials. In this invention, traditional tobacco materials like cut tobacco, broken tobacco and tobacco particles, or other special processed tobacco, like being dry distillation or extracted of tobacco leaf (of course by changing the distillation or extraction level could provide different tobacco taste), low nitrosamine content tobacco, low tar tobacco, protein removed tobacco, low protein carbonized processed tobacco, etc. also can add PG, VG, nicotine, tobacco extract, tobacco flavor, ethanol may apply one or more compositions, among tobacco flavors, like sweeteners, aloes, mint, licorice, essence, etc., could be used to change the taste or flavor of cigarette. Carbon fuel material is porous carbide, solid carbon fuel like charcoal rod, porous carbide herein is carbide made from tobacco leaf, tobacco artificial sheet, by high temperature vacuum distillation partially or completely. Currently, solid carbon rod fuel materials have been commercialized and could be customized and sell, like Premier brand released in 1988 and Eclipse released in 1995 from R.J. Reynolds tobacco are heat-not-burn tobacco products. Apparently, in this invention, cigarette consumable items are working as one time products, it could be traditional cigarette, or tobacco rolled with heat resistance paper, member and aluminum foil. The outside of the cigarette could apply a high temperature baking material as packing, however the packing is the focusing point of this invention, so for examples blow will using aluminum foil, but there is no limitation for this invention.
(29) Aerosol generation consumable items, aerosol generation material refers to liquid which form aerosol after heating and cooling, any liquid in current tobacco product could be applied, like liquid in e-cigarette. As we known, liquid could be categorized into two classes: with nicotine and without nicotine, main composition are PG, VG, nicotine, tobacco extract, tobacco flavor, ethanol may apply one or more compositions, among tobacco flavors, like sweeteners, aloes, mint, licorice, essence, etc., could be used to change the taste or flavor of cigarette; optimized, to fulfill needs, can also add appropriate nicotine and/or tobacco extracts, to replace traditional cigarette products. Aerosol generation material is usually placed in proper container, and conducted by good liquid conduction material like fiber mat, fiber wick consist replaceable or liquid refillable consumable items. In current technology, aerosol generation consumable items are wildly used in e-cigarette, thousands of recipes; there is no limitation in this invention.
(30) Combustion device refers to combustion device using propane gas or butane gas premixed with air to generate flame, ignition and combustion structure is similar to premix lighter. The theory of premix lighter is premix gas with air then combust. Main parts of combustion device are: ignition device and gas storage tank, ignition device can generate and shoot spark to combustion zone to generate flame. Common ignition devices are: piezoelectric ceramic element, magnetic inductance and battery, etc. By using piezoelectric ceramic element, for example, applying mechanical stress on piezoelectric ceramic will cause the element's internal chargers' center change and polarize the element and generate free chargers at both sides of the element. So once the piezoelectric ceramic element being compressed, it could convert mechanical energy to electrical energy, and release high voltage spark at a sharp point to ignite gas. Technicians in this field should understand, the premix lighter is a mature technology. This invention has no limitation to premix lighter, only use it as a combustion device for baking cigarette, will do some necessary modification on its appearance, premix chamber, nozzle and cooperate structure with smoking articles.
(31) Filtering element placed in the cigarette consumable item's puff area or in front of puff mouth piece, filtering element could be used for removing tar and other harmful materials in the smoke, reduce the uncomfortable feel after puff, typical filtering material is made of acetate fiber, polyester, polypropylene mesh. Of course there are some filters with special functions and structures. This invention has no limitation to filters' structure, material and function.
(32) The main idea of this invention is providing a cigarette substitute, with propane gas or butane gas as energy, premixed flame to heat low temperature cigarette, and heat from combustion is for baking cigarette consumable items or aerosol generation consumable items, and generates smoke similar to traditional cigarette.
(33) Applying cigarette consumable items in the smoking article need design reasonable baking chamber in the smoking article. Depends on the length of the consumable item, there could be 1 or more baking chamber, optimized 3-20 baking chamber, the purpose of the baking chamber is match up smoker's smoking habit and rhythm, also bake the cigarette consumable item as uniform as possible. For baking chamber, since the propane gas or butane gas produce waste gas during combustion, should place waste gas emission outlet to the outside world.

(35) Inside the smoking article's housing 1, there are baking chambers 11, separated by partitions 12, all these partitions have reserved with center holes for inserting cigarette consumable items. When inserted with cigarette consumable items 2, each baking chamber 11 is a sealed space, each baking chamber 11 designed a high-temperature gas inlet hole 13 and waster gas outlet hole 14, also the gap between the cigarette consumable item 2, the smoking article's housing 1 and the partition 12 is a high-temperature gas separation path 7, to realize the uniform baking of the cigarette consumable items. Optimized, the high-temperature gas separation path 7 could be designed in 3 to 20's, which means the cigarette consumable item 2 is divided into 3 to 20 sections for baking. Furthermore optimized, to increase the heat efficiency metal fiber or metal foam could be add into the high-temperature gas separation path 7, let the premixed flame and premixed flameless combustion coexistence.
(36) One side of combustion device 3 is placed with liquid propane or butane gas tank 302 and the tank has gas charging valve and gas flow adjust valve, the other side of the gas tank 302 is placed with a push button 303 and stop valve 304, stop valve 304 connected to gas nozzle 305, gas nozzle 305 placed in premix chamber 80 and close to high voltage ignition wire 307, push button 303 connected with piezoelectric ceramic or high frequency device 308 through high voltage ignition wire 307 to premix chamber 80.
(37) Step escapement system is placed on the smoking article's housing; main purpose is to realize the step movement of combustion device on the housing. Control a device moving in steps is a mature technology; there is no limitation for this design. Connection between housing 1, combustion device and step escapement device could apply any current technology. In this invention, to provide a good experience, the push button 303 on combustion device controls not only the single ignition but also the step movement of the escapement system. In
