DETAILED DESCRIPTION

[0018] The structure of the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0019] Example 1

[0020] A physical and chemical heating type heated cigarette smoking device includes an outer shell 1, a bottom cover 7, and a heat transfer assembly. The outer shell 1 is provided with a heating chamber 2 for heating tobacco material and a heat source chamber 3 for providing a heat source. The heating chamber 2 is located above the heat source chamber 3, and the heat source chamber 3 contains a self-heating material. The outer sides of the heating chamber 2 and the heat source chamber 3 are provided with a first heat insulation layer 41, a heat preservation layer, and a second heat insulation layer 42, from the outside to the inside. The heat transfer assembly extends upward from the upper part of the heat source chamber 3 to the heating chamber 2 and penetrates the heating chamber 2. The outer periphery of the second heat insulation layer 42 is connected to the outer shell.

[0021] The self-heating material includes a liquid capsule 8 and a solid heating material 9. The liquid capsule 8 is located on the upper part of the solid heating material 9. The liquid capsule 8 and the solid heating material 9 are wrapped together with tin foil material to form a cylinder with an open top. The upper surface does not need to be wrapped. The diameter of the cylinder is 0.1~0.5mm smaller than the inner diameter of the heat source cavity 3. This design facilitates the loading of the self-heating material and prevents the liquid from spilling out after the liquid capsule 8 is punctured. The liquid inside the liquid capsule 8 is water, and the outer capsule material is one or more of gelatin, pectin, and chitosan. The solid heating material 9 is one or more of quicklime, iron powder, aluminum powder, sodium chloride, and activated carbon. The mass of the solid heating material 9 is 5~10g, and the mass of the liquid is 1.5~3.5g. The internal temperature of the self-heating material can be higher than 300℃, meeting the heating requirements of heated cigarettes.

[0022] Specifically, the heating chamber 2 is 15-20 mm long and 8-12 mm in diameter. The heat source chamber 3 is located at the bottom of the housing and is used to house the self-heating material. The heat source chamber 3 is 5-8 cm long and 10-15 mm in diameter. The heating chamber 2 and the heat source chamber 3 are connected concentrically.

[0023] Specifically, the heat transfer component includes a main heating needle 5 and an auxiliary heating needle 6. The auxiliary heating needles 6 are distributed in a circle around the main heating needle 5. The diameter of the main heating needle 5 is larger than that of the auxiliary heating needle 6. There are ≥2 auxiliary heating needles 6.

[0024] Specifically, a twist-off bottom cover 7 is provided at the lower portion of the housing 1 for loading and removing the self-heating material.

[0025] Specifically, the heating chamber 2 is made of a metallic heat-conducting material, including one of copper, aluminum, a copper alloy, and an aluminum alloy. The heat generated by the self-heating material 9 is partially transferred to the heating needles (5 and 6) to heat the tobacco material from within, and partially transferred to the walls of the heating chamber 2 to heat the tobacco material from outside, ensuring that the tobacco material is fully and evenly heated.

[0026] The heat source cavity 3 is made of a material selected from ceramic and steel. The inner wall of the heat source cavity 3 is coated with a high-temperature resistant heat-insulating coating to reduce heat loss.

[0027] Specifically, the heat transfer component is made of a metallic heat-conducting material, either a single metal or an alloy. The main heating needle 5 is cylindrical with a diameter of 1-2 mm, while the auxiliary heating needle 6 is cylindrical with a diameter of 0.3-0.8 mm. Heat energy from the self-heating material is transferred through the heat transfer needles to the tobacco, causing the tobacco to volatilize. The auxiliary heating needle 6 helps the tobacco heat more evenly.

[0028] Specifically, the first and second insulation layers 41, 42 are 0.5-2 mm thick and are made of one or both of aerogel felt, ultrafine glass wool, and high-silica wool. The thermal insulation layer is 1.5-2.5 mm thick and is filled with expanded vermiculite powder. The outer shell 1 is made of a high-temperature insulating material, including PC, ABS, a composite of PC and ABS, metal, or a metal alloy. The heating chamber 2 and heat source chamber 3 may have different diameters. The difference in their outer walls can be adjusted by increasing the thickness of the first insulation layer or the insulation layer on the outer wall of the heating chamber 2.

[0029] Specifically, when in use, the self-heating material is inserted into the heat source cavity, and the heat transfer needles (5, 6) pierce the liquid capsule. After the heat transfer needles (5, 6) pierce the liquid capsule, the self-heating material can be gently twisted left and right to allow the liquid water to flow smoothly into the solid heating material 9 below. The solid heating material 9 begins to heat up after contact with the water. The bottom cover 7 is tightened, and the heated cigarette is inserted. After waiting for 10 seconds, it can be smoked. This smoking device can meet the needs of smoking more than 8 cigarettes, with sufficient smoke and stable smoke release. After smoking the cigarette, the bottom cover is unscrewed, the heating material is poured out or cleaned with tools, and the self-heating material can be refilled for the next smoke.
