The present invention relates to a preparation method of a porous ceramic, the porous ceramic, and a use thereof in the electronic cigarette. The method of preparing a porous ceramic includes: mixing amorphous silica, aluminum oxide and iron oxide uniformly to obtain a mixture; sintering the mixture at a temperature of 1000° C. to 1400° C. for 0.5 hour to 3 hours to obtain a precursor; grinding the precursor to obtain precursor powder; mixing the precursor powder, sodium silicate, and porogen uniformly to obtain a premix; mixing and extruding the premix with water to obtain a molded body; and heat preserving the molded body at a temperature of 200° C. to 600° C. for 1 hour to 6 hours, and sintering the molded body at a temperature of 700° C. to 1200° C. for 0.5 hour to 3 hours to obtain the porous ceramic.

The invention relates to a phase transition temperature adjusting cup, which comprises a cup body outer casing, a cup body inner casing and a top cover, and the composite phase transition material is filled between the inner casing and the outer casing. The composite phase transition material comprises phase transition material, a nucleating agent, heat conduction filling material and a thickening agent. The phase transition material is selected from one or more of sodium acetate trihydrate, sodium thiosulfate pentahydrate, twelve disodium hydrogen phosphate, sodium sulfate decahydrate and decahydrate. <{EN4}>The nucleating agent is selected from one or more of borax, sodium phosphate dibasic anhydrous, diatomaceous earth, silica, sodium silicate, eight water strontium hydroxide, hexahydrate chloride strontium. <{EN5}>The heat conduction filling material is selected from one or more of graphite, carbon nanotube, expanded graphite, carbon fiber, graphene, three-dimensional graphite foam, silicon carbide, copper powder. <{EN6}>The thickening agent is selected from one of polyacrylic acid emulsion or carboxymethylcellulose sodium. <{EN7}>Compared with existing temperature adjusting cups, the phase transition temperature adjusting cup of the present invention has the advantages of rapid cooling, simple structure convenient operation, 3-4 hours of comfort temperature zone, and not being restricted from external environment.
