Problems solved by technology

However, although the traditional porous material has good adsorption and oil conduction performance, there is still the problem of oil leakage during repeated use. Although the oil leakage can be absorbed through organic cotton, when the atomization device is continuously sucked, it is located in the heating element. It is difficult for the nearby organic cotton to absorb the leaked oil in time, and it is easy for the heating element to directly burn the organic cotton, which will carbonize the organic cotton and cause the gas formed by atomization to have a burnt and gelatinized odor

preparation example Construction

[0040] The above-mentioned porous material adopts specific preparation raw materials, and the preparation raw materials include inorganic aggregates, pore-forming materials and binders in specific proportions, wherein the pore-forming materials include at least one of charcoal and natural organic carbon materials, and the binder can The inorganic aggregate and the pore-forming material are wrapped and gradually solidified to form a bonded solid. At the same time, the pore-forming material in the bonded solid can shrink through carbonization to form pores. The synergy of the binder and the aggregate enables the prepared porous material to have suitable pore size and porosity, thus, the oil adsorption effect is good, that is, the oil guiding effect is good, and oil leakage can be avoided.

[0041] The pore size of the above-mentioned porous material can reach 2 μm˜100 μm, and the porosity can reach 70%.

[0042]It should be noted that when a numerical range is disclosed herein, ...

Description

technical field [0001] The invention belongs to the technical field of functional materials, and in particular relates to a porous material and a preparation method thereof, an atomizing core and an atomizing device. Background technique [0002] The atomizing device refers to a device that heats the stored atomizable substances, such as oil, to form atomized gas, which is then inhaled or utilized. The core component of the atomization device is the atomizing core, which mainly includes the core and the heating component. The core is used to adsorb and store the substances that can be atomized, and it is also the main place where atomization occurs. The atomization process includes: the core absorbs and conducts the atomizable substances, the heating element disposed on the surface of the core heats the core, and the heat is transferred to the atomizable substances absorbed by the core, so that atomization occurs. [0003] The core body is generally a porous material with c...
