The principle of the heating and non-burning is that the heating equipment is used for low-temperature baking of the tobacco without burning. The burning of objects produces many new components, such as common plastics, paper, coal, etc., which are very stable in form and taste, and upon burning, give off black smoke and a pungent odor, which are not present when unburned. The same principle is adopted in daily smoking, a smoker ignites tobacco and then absorbs smoke generated by combustion, and thousands of substances generated by combustion of the tobacco are inhaled into the body together when nicotine is taken, and the substances generated by combustion cause great harm to the body of the smoker. The special tobacco is heated and baked by the heating equipment, and the temperature is controlled within the range below the ignition point, so that the nicotine and various aromatic substances in the tobacco can be baked, and harmful substances generated by combustion are avoided. The low-temperature non-combustion equipment has the taste and flavor closest to those of cigarettes, has unique fragrance of tobacco, simultaneously avoids most of toxic and harmful substances generated by high-temperature combustion, and receives attention of extensive smokers once the low-temperature non-combustion equipment is brought out. Meanwhile, flavoring is added in the heated non-combustible cigarettes as a new way for enhancing and supplementing the flavor, the added flavor is added into tobacco products through a carrier, the flavor is released through suction, in the prior art, a tobacco technology person develops a filter tip as the carrier for supplementing the flavor of main stream smoke, and flavor are mainly applied to filter tip materials through a capsule method, a flavor line method, an adsorbent method and the like to prepare cigarettes with different flavors.

In a specific embodiment, the present embodiment provides a heating tube structure, which may be a mouthpiece of a tobacco product. Specifically, the heating tube structure includes a tube body 1.

And a heating chamber 2 is provided at one end of the tube body 1, wherein the heating chamber 2 is used for heating a non-smoke-generating body (non-tobacco-generating body) or a tobacco-generating body, so that a section of the tube body 1 having the heating chamber 2 may also be referred to as a smoke generating section. The heating cavity 2 is used for heating the internal fuming body through an electric heating wire so as to enable the fuming body to fuming, and other heating devices can be used for heating. And wherein the smoke generating body may be a tobacco smoke generating body; of course, other fuming bodies, i.e., non-fuming bodies, are also possible. Wherein the side of the heating chamber 2 facing the suction nozzle 3 should be provided with a smoke vent to facilitate the flow of smoke towards the suction nozzle 3 at the other end.

And the other end of the tube body 1 is provided with a suction nozzle 3, wherein the suction nozzle 3 is used for holding or indirectly communicating with the oral cavity of a human body, so that the smoke formed by the heating cavity 2 can be sucked through the suction nozzle 3. In which case for some smoke bodies it may be necessary to provide a filter structure in the mouthpiece 3 so that the smoke body is filtered by the filter structure and then enters the mouth of the person, so that the mouthpiece 3 may also be referred to as a filter section. Wherein, the heating cavity 2 is arranged at one end of the tube body 1, the suction nozzle 3 is arranged at the other end, so that the heating cavity 2 and the suction nozzle are communicated, at least a smoke channel can be formed, so that smoke formed at the heating cavity 2 can enter the suction nozzle 3 and flow out from the suction nozzle 3 to enter the oral cavity of a human body.

Wherein the channel between the suction nozzle 3 and the heating cavity 2 is filled with a cooling structure 4, so that the high temperature gas formed at the heating cavity 2 can enter the suction nozzle 3 after being cooled by the cooling structure 4, and then enter the oral cavity through the suction nozzle 3. The cooling structure 4 is a structure capable of cooling high-temperature flue gas, for example, the structure can be made of heat absorbing materials, or a high-efficiency heat dissipation structure can be adopted, and the cooling structure is specific, so that the cooling of the high-temperature flue gas can be achieved, and the requirements are met.

In the heating pipe structure, when in use, a non-smoke fuming body or a tobacco fuming body is placed in the heating cavity 2, the heating function of the heating cavity 2 is started, and then the mouth of a human body contains the suction nozzle 3 or the indirect butt joint suction nozzle 3, so that suction force is generated to the suction nozzle 3 when the oral cavity inhales. Under the action of suction force, high-temperature flue gas in the heating cavity 2 enters the cooling structure 4, heat is absorbed by the cooling structure 4 and the high-temperature flue gas, so that the highest temperature of the flue gas can be reduced, and then the cooled flue gas enters the oral cavity through the suction nozzle 3. In this add pipe structure, set up cooling structure 4 between suction nozzle 3 and heating chamber 2 to can cool down through the high temperature flue gas that cooling structure 4 formed heating chamber 2, in order to satisfy the needs of human oral cavity to flue gas temperature, and then fine promotion human oral cavity's suction experience. In summary, the heating pipe structure can effectively solve the problem that the suction effect is poor due to the fact that the temperature of the smoke of the suction nozzle 3 of the current heating pipe structure is too high.

The cooling fins 6 cannot generally be placed perpendicular to the tube body 1 to avoid affecting the rapid flow of flue gas. The specific cooling fin 6 that can make is arranged side by side in proper order along the transverse direction of body 1, forms the clearance each other to make things convenient for the cigarette body to pass through, and the cigarette body is in the in-process that passes through with cooling fin 6 contact, is absorbed heat in order to cool down.

One problem that needs to be addressed here is. Wherein after the cooling structure 4 absorbs heat from the high temperature flue gas: this heat can be rapidly discharged to the outside environment through the structure; or may be without draining. The reason for this is that for some cooling structures 4, the heat absorption capacity is high, such as a substance with a relatively large heat capacity, and the temperature rises less than the flue gas temperature after continuously absorbing heat from the flue gas during one smoke generation. After one smoke generation, the heating pipe structure can be disposable, so that the heating pipe structure is not used any more; if the heating pipe body 1 can be reused, the heating pipe body can be reused for a long time after one smoke generation, and the cooling structure 4 can slowly cool down in the atmospheric environment. Therefore, the cooling structure 4 can be selected to be exposed or embedded as required.

In some embodiments, the cooling fin 6 may be spirally wound around the central line of the extending direction of the tube body 1. So that the larger clearance channel is formed, and the manufacture is simple and convenient. The cooling sheet 6 may be a metal sheet, a phase change material, or a polylactic acid sheet.

In some embodiments, the cooling device preferably further comprises a paper tube 7, wherein the paper tube 7 is sleeved outside the cooling structure 4, and the inner wall of the paper tube 7 is fixedly connected with the cooling structure 4. For the convenience of connection, the inner wall of the paper tube 7 and the cooling structure 4 can be bonded, namely, adhesively connected. If a sheet is used, it is wound around one end, with a gap remaining during winding, and then the other end is attached to the inner wall of the paper tube 7. The vortex structure is independently manufactured and then is plugged into the paper cylinder, and is adhered to the inner wall of the paper cylinder 7.

In some embodiments, the cooling structure 4 may be provided with a fragrance layer on its surface. Specifically, the surface of the cooling structure 4 can be provided with the spice layer through dip coating, and the spice layer can volatilize under the action of high-temperature flue gas so as to form aroma enhancement and aroma supplementing effects on the flue gas, so that the aroma of the pumped flue gas is more intense, the sensory enjoyment of consumers is greatly improved, the temperature of main stream flue gas can be reduced to a certain extent, and the pumping experience of the consumers is improved. The specific fragrance layer can be added according to the need. Specifically, for example, before the cooling structure 4 is formed, the cooling fin 6 may be immersed in the perfume, so that a perfume layer is formed on the surface.

In some embodiments, the cooling structure 4 may be a honeycomb structural member, and the honeycomb structural member is a polylactic acid material piece.

In some embodiments, a hollow rod 5 may be further disposed between the cooling structure 4 and the suction nozzle 3, for filtering and limiting the cut tobacco, and the hollow is used for preventing the heating needle from being inserted into the filtering material to burn the cut tobacco.
