Abstract: An atomization assembly includes: a housing assembly having a liquid storage chamber, an air outlet channel, and an atomization chamber, the liquid storage chamber being storing a substrate; and an atomization core for atomizing the substrate to generate an aerosol, an atomization surface of the atomization core being exposed to the atomization chamber and substantially parallel to the air outlet channel, the atomization chamber communicating with the atomization surface of the atomization core and the air outlet channel.

Abstract: The disclosure belongs to the technical field of food additives, and provides a method for preparing a calcium carbonate-based edible lake. The method comprises the following steps: S1, dissolving carbonate in water to obtain carbonate solution; S2, dissolving water-soluble anionic pigment into the carbonate solution obtained in step S1 to obtain mixed solution; S3, adding hydrochloric acid to the mixed solution obtained in step S2 to adjust pH to 7-10.5; S4, dissolving a calcium salt into water and then adding the above solution into the solution obtained in step S3, controlling the pH of the mixed solution to 6-9, carrying out ultrasound treatment for 1-10 min, centrifuging to obtain a calcium carbonate precipitate adsorbed with pigment; and S5, drying and grinding the calcium carbonate precipitate adsorbed with pigment obtained in step S4 to obtain the calcium carbonate-based edible lake.
