[0040] The electromagnetic coil 12 can be a group or multiple groups. By placing a cigarette into the burner 1, the cigarette has metal wire or metal sheet inside. At this time, the electromagnetic coil 12 is energized, and the outer tube 11 is heated by the electromagnetic heating principle while heating the metal wire or metal sheet inside the cigarette, so that the cigarette burns smokelessly.

[0042] The inner tube 3 is made of one or more of metal material, PEEK material or high-temperature quartz material. The inner tube 3 made of one or more of metal material, PEEK material or high-temperature quartz material has good thermal conductivity and high temperature resistance.

[0045] A method for manufacturing an insulation pipe structure of a combustion atomizer,

[0046] Step 1: Select the base material; the base material can be any one or more of rubber material, melamine foam, polyimide, polyurethane, PU, ​​and PET material;

[0047] Step 2: Weigh the substrate and perform corresponding foaming treatment according to its density and material;

[0048] The third step: thickness cutting; make the height and inner wall thickness of the insulation pipe match the height and inner wall thickness of the outer tube 11 and the inner tube 3;

[0049] Step 4: Integral molding, so that the insulation pipe is in an integral molding state;

[0050] Step 5: Use the appropriate solution to soak the substrate for molding;

[0051] Step 6: Extract the solvent with supercritical carbon dioxide;

[0052] Step 7: Use a supercritical dryer to dry the base material and finally form it.

[0053] In one embodiment, the integral molding of the thermal insulation pipe includes a molding method selected from the group consisting of laser engraving molding, cutting molding, die-cutting molding, and stamping molding.

[0054] In one embodiment, the immersion molding method is:

[0055] Mixing the silicon source, water and alcohol solution according to a preset ratio to form a mixed solution;

[0056] treating the mixed solution to form a sol;

[0057] The gel is polymerized to form a wet gel;

[0058] The wet gel forms an alcohol gel under the action of a catalyst;

[0059] The alcohol gel is supercritically dried to form an aerogel.

[0060] The first and second insulated tubes 2 and 4 are made of aerogel insulation, a composite material. It's a mixture of flexible fibers and SiO2 aerogel. Its design is based on SiO2's ultra-small pore size (20-50 nm), achieving a minimum thermal conductivity of 0.013 W / mk, lower than the conductivity of air (0.025 W / mk). The support and temperature resistance of flexible flame-retardant fibers address SiO2's fragility and performance distortion at high temperatures (above 380 degrees Celsius). The combination of these two materials achieves optimal performance.

[0061] Three main pathways of heat conduction:

[0062] 1. Solid phase conduction,

[0063] 2. Convection conduction,

[0064] 3.Radiation conduction.

[0065] SiO2 aerogel solves three major conduction pathways:

[0066] 1. Conduction: Due to the existence of nearly infinite nanopores, heat flow in solids can only be transferred along the pore walls. The nearly infinite pore walls constitute a nearly "infinite path" effect, which reduces the heat conduction capacity of solids to near the minimum limit;

[0067] 2. Convection: When air molecules are in pores smaller than 70nm, they lose the ability to flow freely and relatively adhere to the pore walls. At this time, the aerogel material is in a near vacuum state.

[0068] 3. Radiation: Since the pores in the material are all nano-scale pores and the volume density of the material itself is extremely low, the number of pore walls inside the material tends to be "infinite". Each pore wall acts as a heat shield, thus producing an effect close to "infinite heat shields", thereby reducing radiation heat transfer to almost the lowest limit.

[0069] Preparation process of SiO2 aerogel high-efficiency composite materials:

[0070] The silicon source, water and alcohol solution are mixed according to a preset ratio and then stirred to generate a SiO2 solvent. The generated solvent is combined with the flexible fiber material, mixed, gelled, and a flexible fiber-enhanced SiO2 aerogel is generated. The material currently used is produced by aging and supercritical drying (37 degrees, 22MPA, 1-2 days).

[0071] Aerogel is a nanomaterial with a three-dimensional network structure that has high porosity and a high specific surface area. Its unique nanostructure effectively inhibits both solid heat conduction and gas convection heat transfer, making it a "super thermal insulation material" with excellent performance.

[0072] Furthermore, the process of converting a solution into a colloid can be achieved through a variety of methods, including sol-gel method, precipitation method, emulsification method, co-precipitation method and ion exchange method.

[0073] The sol-gel method involves mixing a solvent and a dispersed phase substance and stirring them thoroughly. After a sol is formed, a gelling agent is added. The dispersed phase substance in the sol is formed into a colloid through the action of the gelling agent. Finally, a pure colloid is obtained through filtration, centrifugation and other treatments.

[0074] The precipitation method is to mix the solution of the dispersed phase substance with the precipitant. Through the action of the precipitant, the dispersed phase substance forms a colloid and precipitates in the solution. Finally, the pure colloid is obtained by filtering, centrifuging and other treatments.

[0075] The emulsification method involves mixing the dispersed phase material with the emulsifier and stirring it thoroughly under appropriate conditions. The emulsifier disperses the dispersed phase material in the continuous phase material to form an emulsion colloid. Finally, the pure emulsion colloid is obtained through centrifugation, filtration and other treatments.

[0076] The co-precipitation method involves mixing and fully stirring solutions of two or more dispersed phase substances, adding a precipitant to allow the dispersed phase substances to precipitate together and form a colloid, and finally obtaining a pure colloid through filtration, centrifugation, and other treatments.

[0077] The ion exchange method involves contacting a solution of dispersed phase material with a resin or material with ion exchange function to conduct a sufficient ion exchange reaction, forming ion colloids through ion exchange, and finally obtaining pure ion colloids through filtration, centrifugation and other treatments.

[0078] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
