Embodiment 1, as shown in fig. 1 to 7, an atomizing heating assembly includes a porous liquid guiding body 100 and a porous magnetic conductive heating body 200, where the porous liquid guiding body 100 is a porous structure body formed by sintering an inorganic non-metallic aggregate and a binder at a high temperature and having micron-sized pores, the micron-sized pores formed by sintering the inorganic non-metallic aggregate and the binder at a high temperature can provide a channel through which an atomizing liquid passes, and the porous liquid guiding body 100 has high strength and can provide structural support and thermal insulation; the porous magnetic conductive heater 200 is a porous magnetic conductive structure body formed by directly sintering magnetic conductive material particles at a high temperature or sintering the magnetic conductive material particles in cooperation with an adhesive at a high temperature, namely the porous magnetic conductive structure body has two realization modes: firstly, magnetic conductive material particles are directly sintered at high temperature, secondly, the magnetic conductive material particles are sintered at high temperature by matching with an adhesive, micron-sized micropores are formed, and the formed porous magnetic conductive structure body not only can generate heat through electromagnetic induction, but also can have a liquid guide function through the micron-sized micropores; the porous magnetic conductive heating body 200 is at least embedded or attached to the surface of the porous conductive liquid 100, and it can be understood that the porous magnetic conductive heating body 200 can be embedded or attached to any surface of the porous conductive liquid 100, the porous magnetic conductive heating bodies 200 can be arranged in plurality at intervals, or one porous magnetic conductive heating body 200 can be arranged continuously, a plurality of porous magnetic conductive heating bodies 200 can be embedded or attached to one surface of the porous conductive liquid 100, or a plurality of porous magnetic conductive heating bodies 200 can be embedded or attached to different surfaces of the porous conductive liquid 100. As shown in fig. 2, the engagement according to the present invention may be partial engagement, that is, a part of the porous magnetic conductive heating body 200 is embedded in the porous liquid conductive body 100, and a part of the porous magnetic conductive heating body exceeds the surface of the porous liquid conductive body 100, as shown in fig. 1, the engagement may also be full engagement, that is, the porous magnetic conductive heating body 200 is fully disposed in the porous liquid conductive body 100, that is, the surface of the porous magnetic conductive heating body 200 is flush with the surface of the porous liquid conductive body 100. The porous magnetic conductive heater 200 may be disposed continuously or discontinuously on the surface of the porous liquid conductive body 100, or disposed on the entire surface of the porous liquid conductive body 100, including on each surface of the porous liquid conductive body 100, on a portion of the surface of the porous liquid conductive body 100, or on any surface of the porous liquid conductive body 100; and the exposed surface of the porous magnetic conductive heating body 200 located in the atomization channel forms an atomization surface 21, it can be understood that the porous magnetic conductive heating body 200 is arranged in the atomization channel, and the exposed surface of the porous magnetic conductive heating body 200 is the atomization surface 21. The porous magnetic conduction heating body 200 is used as a heating layer, and has the porous characteristic that magnetic conduction metal particles in the porous magnetic conduction heating body generate heat due to the electromagnetic effect, and the porous characteristic ensures that the liquid is fully supplied and atomized steam can smoothly emerge from micropores, so the heating layer can be made into the effect that the whole surface generates heat, the heat efficiency of the same area is higher, the porous magnetic conduction heating bodies 200 at other positions also have the liquid guiding function and the heating function, and the porous magnetic conduction heating bodies 200 at other positions can also be used as heating preheating parts to preheat and atomize the atomized liquid of the porous magnetic conduction liquid 100 at the attachment part or the scarf joint part, thereby improving the atomization effect and improving the taste of the atomized steam; when the atomizing heating component works, the atomized tobacco tar is guided to the atomizing surface 21 of the porous magnetic conductive heating body 200 by the porous magnetic conductive liquid 100, the porous magnetic conductive heating body 200 generates heat through an electromagnetic effect, the tobacco tar is atomized to form atomized steam, and the atomized steam and air form aerosol which is finally sucked by a user.
Besides the porous magnetic conductive heating body 200 is embedded or attached on the surface of the porous liquid conductive 100, the porous magnetic conductive heating body 200 can also be embedded in the porous liquid conductive 100 for preheating the liquid, improving the flow rate of the liquid and accelerating the guiding atomization surface 21.
The contact part with the sealing element 50 is preferably not provided with the porous magnetic-conductive heating body 200, because most of the sealing element 50 is made of rubber, plastic and the like, and the contact part of the surface of the porous magnetic-conductive liquid 100 and the sealing element 50 is not provided with the porous magnetic-conductive heating body 200, so that the sealing effect of the sealing element 50 is prevented from being influenced by the burning deformation or burning damage of the sealing element 50 due to continuous heat generation of the porous magnetic-conductive heating body 200.
The thickness of the porous liquid conducting body 100 is larger than that of the porous magnetic conductive heating body 200. The porosity of the porous liquid guiding 100 is between 30% and 70%, the diameter of the micropores is between 5 μm and 100 μm, and the thickness of the porous liquid guiding 100 is greater than that of the porous magnetic conductive heating body 200 because the tobacco tar atomization temperature is generally 180-.
In addition, the thickness of the porous magnetic conductive heating body 200 provided with the atomizing surface 21 is greater than the thickness of the porous magnetic conductive heating bodies 200 at other positions, so that the heating temperature per unit area of the porous magnetic conductive heating body 200 on the atomizing surface 21 is higher than the temperature on the porous magnetic conductive heating bodies 200 at other positions, more of the porous magnetic conductive heating bodies 200 on the atomizing surface 21 play a role in heating and atomizing, the heating temperature per unit area needs to be higher, so that the porous magnetic conductive heating bodies 200 at other positions can play a role in preheating atomized liquid, the heating temperature per unit area can be lower, and the thickness of the porous magnetic conductive heating bodies 200 can be smaller than that of the porous magnetic conductive heating bodies 200 at the atomizing surface 21.
The atomizing surface 21 of the porous magnetic conductive heating body 200 is provided with an air guide 300 which is arranged along the air flow direction and is used for guiding air and increasing the atomizing area.
