The filter segment 2 is made of breathable filter material, and the breathable filter material has many pores or gaps inside to allow air or smoke to penetrate, but can filter out harmful substances, impurities and tar condensation particles in the smoke. The smoking segment 4 is composed of smoke forming matrix material, which can produce smoke after being heated. The proximal end 11 of the smoking article is one end of the mouthpiece, and the distal end 12 of the smoking article is one end inserted into the heating not combustible electronic cigarette (not shown in the figure).

[0028] The filter segment 2 is made of breathable filter material, and the filter material includes polymeric material or cellulose acetate. The filter segment 2 can filter out harmful substances, impurities and tar condensation particles in the smoke.

[0029] The hollow cooling segment 3 is composed of a hollow paper tube 31, and air can flow freely in the paper tube 31 to form a hollow air duct 30. The length of the hollow cooling segment is set to 15-35mm, and the hollow air duct 30 formed in the length range has good cooling effect through test. When the user smokes, the high-temperature smoke generated in the smoking segment 4 is first sucked into the hollow paper tube 31 and mixed with the original low-temperature air in the paper tube 31, which can rapidly reduce the temperature of the smoke to make its temperature suitable for the mouth. In addition, the paper tube 31 is a hard paper tube, that is, the hollow paper tube has a certain hardness and will not soften even in a high-temperature working environment, so as to support the tubular hollow cooling segment 3 and prevent it from deforming and affecting the internal hollow air duct.

[0030] The wall of the paper tube 31 and the wall of the outer cigarette paper 1 are provided with several air inlet holes 310 at the same position. When the user smokes, the outside air can enter the paper tube through these air inlet holes 310 and mix with the high temperature smoke, further reducing the temperature of the smoke and making it suitable for inhalation.

[0031] The smoke-generating section 4 is composed of a smoke-forming matrix material, which produces smoke when heated. The smoke-forming matrix material may adsorb nicotine preparations, and / or flavoring agents, and / or taste agents. These preparations may emit a smell that mimics tobacco when heated, or may add or harmonize the aroma, or may add flavors such as mint or fruit.

[0032] The smoke-forming matrix material of the smoke-generating section 4 is composed of a bundle of several slender tobacco sticks. The tobacco sticks can be made of tobacco material pressed into round or flat slender strips, and several tobacco sticks can be rolled into a bundle to form the smoke-generating section. In other embodiments, the smoke-forming matrix material can also be composed of many tobacco particles made of tobacco material.

[0033] Leak-proof section 5 is made of breathable absorbent material that can absorb liquid components such as soot and tar.

[0034] The filter material in this embodiment includes cellulose acetate and / or polymeric materials.

[0035] Example 2

[0036] like Figure 2 As shown, based on Embodiment 1, the heated non-combustible smoke-generating product of Embodiment 2 further includes a hollow portion 21 and a filter portion 22 in its filter section 2. The hollow portion 21 is located on the outer side of the filter section 2, i.e., on the proximal side of the smoke-generating product, and the filter portion 22 is located on the inner side of the filter section 2, i.e., on the side of the filter section 2 facing the hollow cooling section 3. The filter portion 22 is made of a breathable filter material. The hollow portion 21 includes a circular tube layer 211, with a central through-hole 210 at its center to form a smoking channel. The circular tube layer 211 is made of a breathable filter material. In other embodiments, the circular tube layer 211 may also be made of a non-filter material, such as a hard material that is not easily thermally conductive, to better prevent burns to the mouth.

[0037] The hollow section 21 is provided with a central through hole 210, so that when the user smokes, the hot smoke is mainly drawn out through the central through hole 210 and can be further mixed with the original low temperature air in the central through hole 210, so as to further reduce the temperature of the smoke inhaled into the mouth. At the same time, less heat is conducted from the smoke to the circular tube layer 211, so the temperature of the hollow section 21 that comes into contact with the lips is moderate, avoiding scalding the mouth.

[0038] The rest of this second embodiment is the same as that of the first embodiment.

[0039] The utility model discloses a heating non -combustion smoking article, including the filter tip section 2, hollow cooling section 3, smoking section 4 and the leakage prevention section 5 who set up in sequence, when the user smokes, filter tip section 2 is placed in the mouth, smoking section 4 is inserted into the electronic smoking set and is heated and baked and produces high temperature smoke, the outside air enters from the leakage prevention section 5, carries high temperature smoke when passing through smoking section 4 and further enters the hollow air passage 30 in hollow cooling section 3, and mixes with the original low temperature air in the hollow air passage 30, can rapidly reduce the temperature of smoke.

[0040] In the case where filter tip section 2 further includes hollow part 21 and filter part 22, when smoke further passes through the hollow part 21 of filter tip section, smoke flows through the center through hole 210 and mixes with the original low temperature air in the center through hole 210, which can further reduce the temperature of smoke in the suction port, and at the same time, less heat in the smoke is conducted to the circular tube layer 211, so that the temperature of the hollow part 21 in contact with the lips of the mouth is moderate, avoiding scalding the mouth.

[0041] In addition, when the user smokes, the smoke forming base material in smoking section 4 is heated and baked at high temperature, which is easy to produce liquid components such as tobacco tar and tar to drip and leak into the inner bottom of the baking assembly of the smoking set, and after a long time, it is difficult to clean after solidification, at the same time, the debris of the smoke forming base material itself and the debris generated after high temperature baking of the smoke forming base material may also fall into the inner bottom of the baking assembly, which affects the heat transfer effect of the baking assembly and produces the smell of burning impurities during use. The leakage prevention section 5 of the utility model is made of breathable adsorbent material, which can absorb liquid components such as tobacco tar and tar, prevent liquid components such as tobacco tar and tar and debris from leaking into the inner bottom of the baking assembly, and ensure the heat transfer effect of the baking assembly and avoid the generation of the smell of burning.

[0042] The above description is only the preferred embodiment of the utility model, and the above specific embodiment is not a limitation of the utility model. Within the technical concept of the utility model, various modifications and modifications can occur, and any modification, modification or equivalent replacement made by those skilled in the art according to the above description belongs to the scope of protection of the utility model.
