BRIEF DESCRIPTION OF DRAWINGS
[0022] Figure 1 It is a sectional view of the smoking article with the inner and outer leakage prevention segments in Example 1.
[0023] Figure 2This is a cross-sectional view of the smoke-generating product with internal and external leak-proof sections in Example 2. Detailed Implementation
[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.
[0025] This utility model discloses a smoke-generating product with internal and external leak-proof sections, which can be inserted into a heated non-combustible electronic cigarette device for heating and baking to generate smoke for the user to inhale.
[0026] Example 1
[0027] like Figure 1 As shown, the smoking product with internal and external leak-proof sections in this embodiment includes an outer layer of cigarette paper 1 wound into a cylindrical shape. Inside the outer layer of cigarette paper 1, a filter section 2, a hollow cooling section 3, an inner leak-proof section 4, a smoking section 5, and an outer leak-proof section 6 are sequentially connected. The filter section 2, hollow cooling section 3, inner leak-proof section 4, smoking section 5, and outer leak-proof section 6 are tightly wrapped by the outer layer of cigarette paper 1 and formed into a single unit. The proximal end 11 of the smoking product is the end that enters the mouth, and the distal end 12 is the end that is inserted into a heated non-combustible electronic cigarette device. The filter section 2 is made of a breathable filter material. The breathability of the filter material means that it has many pores or gaps inside, allowing air or smoke to pass through, while filtering out harmful substances, impurities, and tar particles in the smoke. The smoke-generating section 5 is made of a smoke-forming matrix material, which can generate smoke after being heated and baked. The proximal end 11 of the smoke-generating product is the end that is inserted into the mouth, and the distal end 12 of the smoke-generating product is the end that is inserted into a heated non-combustible electronic cigarette device (not shown in the figure).
[0028] Filter section 2 is made of breathable filter material, including polymeric materials or cellulose acetate. Filter section 2 can filter out harmful substances, impurities, and tar particles from the smoke.
[0029] The hollow cooling section 3 is composed of a hollow paper tube 31, within which air can flow freely to form a hollow air channel 30. The length of the hollow cooling section is set at 15-35mm. Tests have shown that the hollow air channel 30 formed within this length range has a good cooling effect. When a user smokes, the high-temperature smoke generated in the smoke-generating section 5 is first inhaled into the hollow paper tube 31 and mixed with the existing low-temperature air inside the paper tube 31, rapidly reducing the temperature of the smoke to a suitable temperature for inhalation. Furthermore, the paper tube 31 is a rigid paper tube, meaning the hollow paper tube has a certain degree of rigidity and will not soften even in high-temperature environments, thus supporting the tubular hollow cooling section 3 and preventing deformation that could affect the internal hollow air channel.
[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 5 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 flavor that mimics tobacco, or enhance or harmonize the aroma, or add flavors such as mint or fruit when heated.
[0032] The smoke-forming matrix material of the smoke-generating section 5 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] Both the inner leak-proof section 4 and the outer leak-proof section 6 are made of breathable absorbent material, which 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 second embodiment of this smoking product with internal and external leak-proof sections 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 smoking 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, which can 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 in 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 the second embodiment is the same as the first embodiment.
[0039] The smoking article with the inner and outer leakage-proof sections has the filter section 2, the hollow cooling section 3, the inner leakage-proof section 4, the smoking section 5 and the outer leakage-proof section 6 arranged in sequence. When a user smokes, the filter section 2 is placed at the mouth, the smoking section 5 is inserted into the electronic smoking set to be heated and roasted to generate high-temperature smoke, the external air enters from the outer leakage-proof section 6, carries the high-temperature smoke when passing through the smoking section 5 and further enters the inner leakage-proof section 4. The inner leakage-proof section 4 is made of breathable adsorbing material, which can absorb the liquid components such as tobacco tar contained in the high-temperature smoke, prevent the liquid components such as tobacco tar and the debris of the smoke-forming base material itself from leaking inwardly into the hollow cooling section 3, and prevent the debris generated after the smoke-forming base material is heated at high temperature and carbonized. If the liquid components such as tobacco tar and the debris contained in the high-temperature smoke enter the hollow cooling section 3, the liquid components and the mixed debris will condense on the inner wall of the hollow cooling section 3 and the inner end portion of the filter section 2, the inner wall of the paper tube of the hollow cooling section 3 may be softened and deformed or damaged after adsorbing the liquid components, and the inner end portion of the filter section 2 is easily blocked by the condensation of the liquid components and the mixed debris to form an airflow channel, which causes difficulty in inhaling the smoke. Therefore, the inner leakage-proof section 4 can prevent the liquid components such as tobacco tar and the debris from leaking inwardly into the hollow cooling section 3, so as to prevent the paper tube 31 from being softened and deformed or damaged and ensure smooth inhalation of the smoke.
[0040] The high-temperature smoke further enters the hollow air duct 30 in the hollow cooling section 3 and mixes with the original low-temperature air in the hollow air duct 30, so as to rapidly reduce the temperature of the smoke. The paper tube 31 is further provided with a plurality of air inlet holes 310, so that the external air can enter the paper tube through the air inlet holes 310 and mix with the high-temperature smoke, so as to further reduce the temperature of the smoke. When the smoke further passes through the filter section 2, the filter section 2 can filter the impurities and tar particles in the smoke.
[0041] In the case that the filter section 2 further includes the hollow portion 21 and the filter portion 22, when the smoke further passes through the hollow portion 21 of the filter section, the smoke flows through the center through hole 210 and mixes with the original low-temperature air in the center through hole 210, so as to further reduce the temperature of the smoke in the suction port, and the heat conducted to the circular tube layer 211 in the smoke is less, so that the temperature of the hollow portion 21 in contact with the mouth of the user is moderate, avoiding scalding the mouth.
[0042] In addition, when the user smokes, the smoke forming base material in the smoking section 5 is heated and roasted at high temperature, and liquid components such as tobacco tar and tar are prone to drip and leak into the inner bottom of the roasting assembly of the smoking set, and after a long time, it is difficult to clean up after solidification, at the same time, the debris of the smoke forming base material itself and the debris generated after the smoke forming base material is roasted at high temperature may also fall into the inner bottom of the roasting assembly, which affects the heat transfer effect of the roasting assembly and produces impurities burned and scorched in use. The inner leakage prevention section 4 and the outer leakage prevention section 6 of the utility model are made of breathable adsorbing material, the adsorbing material can absorb liquid components such as tobacco tar and tar, can prevent liquid components such as tobacco tar and tar and debris from leaking into the hollow cooling section 3, and can prevent from leaking into the inner bottom of the roasting assembly, so as to ensure the heat transfer effect of the roasting assembly and avoid the generation of scorched smell.
[0043] The above description is only the preferred embodiment of the utility model, and the above specific embodiment is not the 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 protection scope of the utility model.
