Disclosure of Invention
The invention relates to an aerosol generating product of electromagnetic bulk smoking materials, which comprises a pipe 1, an aerosol generating component 2 and a filtering component 4, wherein the aerosol generating component 2 and the filtering component 4 are positioned in the pipe 1 and are sequentially arranged from a far lip end to a near lip end;

The cylinder 51 contains an aerosol generating material in the form of particles, powder, filaments or a smoke generating material in the form of a cigarette paste.
The smoking material is exemplified here, but the present invention is not limited to the above embodiments, and any smoking medium that can be contained in the cylinder 51 may be used.
The "sequential arrangement" is not sequential, that is, the two adjacent aerosol generating component 2 and the filtering component 4 may be closely adjacent, and other components or a cavity may be inserted between the two adjacent components. The other part can be a cooling and flavoring part with a cooling and flavoring material.
When the inner member is used as the aerosol-generating unit 2, a sealing film may be further added to the distal end face of the aerosol-generating article, or the breathable sealing material 52 at the distal end may be used as a seal without using a sealing film.
Preferably, the aerosol generating material further comprises a heat conducting material, and the heat conducting material is selected from metal, stainless steel, alloy material, ceramic or graphene; the heat conducting material in the aerosol generating substrate is in the forms of powder, particles, sheets, rings or springs.

Preferably, the breathable closure member 52 is selected from a gas-impermeable material having a first ventilation aperture 521 formed therein;
or the breathable closure member 52 is selected from breathable materials, with or without a first vent hole 521 thereon;
the first vent hole 521 penetrates the air-permeable sealing member 52 in the axial direction.
Preferably, the material of the cylinder 51 is selected from paper materials, resin materials, non-magnetic metal materials or magnetic metal materials, the resin materials are selected from PEEK, polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate or polylactic acid, the inorganic materials are selected from alumina, silicon carbide, silicon nitride or diatomite, and the non-magnetic metal materials are selected from aluminum or copper; the magnetic metal material is selected from iron, martensitic steel, ferritic steel, austenitic steel, precipitation hardening stainless steel, chromium-nickel stainless steel, chromium-manganese-nitrogen stainless steel and the like.
Preferably, the gas permeable material is selected from a paper material or an inorganic porous material selected from alumina, silicon carbide, silicon nitride or diatomaceous earth; the air-impermeable material is selected from resin materials or magnetic metal materials, the resin materials are selected from PEEK, polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate or polylactic acid, and the magnetic metal materials are selected from iron, martensitic steel, ferritic steel, austenitic steel, precipitation hardening stainless steel, chromium-nickel stainless steel, chromium-manganese-nitrogen stainless steel and the like.
Preferably, the gas-permeable sealing member 52 at least one end is a gas-permeable sealing plug in the form of a sealing cap, which is detachably connected to the cylinder 51;
the breathable closure 52 includes a closure 522 and a closure wall 523; the plug cap 522 is axially located between the upstream end to the downstream end of the plug wall 523.
When the breathable sealing member 52 is made of a magnetic conductive material, the breathable sealing member 52 includes a sealing cap 524 and a heat conducting member 525;
the sealing cap 524 is located at the end of the upstream end of the aerosol generating component 2;
the heat conducting member 525 is connected to the sealing cap 524 at an upstream end thereof, and extends toward the inside of the aerosol generating member 2 at a downstream end thereof, and the heat conducting member 525 is a heat conducting material.
The sealing cap 524 generates an induced current when contacting the electromagnetic heating device, thereby generating heat, and the heat is transferred to the heat conductive member 525, and the heat conductive member 525 heats the aerosol generating member 2, thereby generating aerosol.
Preferably, the sealing cap 524 is provided with a second vent hole 526, and an inner diameter of the second vent hole 526 is smaller than an outer diameter of the aerosol generating material in the aerosol generating component 2, so as to prevent the aerosol generating material from falling off.
Preferably, the upstream end of the heat-conducting member 525 is disposed at the center of the cap 524; the heat conducting component 525 is needle-shaped or sheet-shaped; the heat conducting component 525 is a heat conducting material selected from metal, stainless steel, alloy material, ceramic or graphene, the metal heat conducting material is selected from copper, aluminum, iron and the like, and the ceramic material is selected from oxide, nitride, carbide and boride.
Preferably, the heat-conducting member 525 further has a heat-insulating member 527 at the connection between the upstream end thereof and the sealing cap 524; the heat insulation component 527 is a heat insulation section material and is selected from a metal material or high temperature resistant plastic, the metal material is selected from gold, silver, nickel, aluminum foil and the like, and the high temperature resistant plastic is selected from poly (terephthalic acid) plastics, polyphenylene sulfide, polyether ether ketone, polyarylsulfone, polyphenyl ester, polybenzimidazole, polyborodiphenylsiloxane and the like. The heat insulating member 527 prevents heat generated by electromagnetic induction from concentrating on the upstream end face of the aerosol generating member 2, which causes scorching of the aerosol generating material at the end portion under high heat, and further causes uneven heating of each portion of the aerosol generating member 2.
The material with the functions of cooling, flavoring and reducing harmful substances can be in the form of particles, powder, blasting beads and paste, and aims to lower the temperature of the aerosol, flavor the aerosol and reduce harmful substances in the aerosol.

the pipe fitting 1 is a tubular structure made of a material with certain hardness, and can also be a tubular structure formed by wrapping paper on the aerosol generating component 2 and the filtering component 4. That is, the tube material may be a tubular material having a certain shape and a certain hardness and stiffness, and the aerosol-generating component, the functional component, the filter component, and the like may be directly filled therein to form the aerosol-generating article. Alternatively, the aerosol-generating article may be formed by winding an outer layer of paper after arranging the aerosol-generating member, the functional member, the filter member, and the like in this order.
Preferably, the filter element 4 and the end face of the pipe 1 near the lip end can be flush with each other, and a settling unit can also be left. That is to say, a certain cavity is left between the filtering component 2 and the end face of the pipe body 1 near the lip end, the cavity is a sedimentation unit, and the purpose of the sedimentation unit is two-way: firstly, the oral cavity of a consumer directly contacts with the sedimentation unit instead of the filter component 4 in the smoking process, and the doubt that the oral cavity is considered to directly contact with the filter component 4 and is unsafe by part of consumers is eliminated; secondly, the existence of the sedimentation unit can also better prevent the filter component 4 from being polluted in the production process, thereby improving the production quality.
