Abstract
A cooling cigarette filter and a smoking product are provided. The cooling cigarette filter comprises a cooling section. The cooling section is provided with one or more channels connecting two ends of the cooling section, and an inner surface of each channel is coated with a cooling material. The cooling material comprises an inorganic phase change material and PEG, and the inorganic phase change material comprises at least one of Na2CO3·10H2O, CH3COONa·3H2O, CaCl2·4H2O, and Na2SO4·10H2O. The cooling cigarette filter has the advantages of ensuring the amount of smoke and lowering the temperature of the smoke entering the mouth, especially in the cooling section. Through the combination design of the structure of the cooling stick and the type and amount of the cooling material, the smoke can flow out of a smoke generation section rapidly and smoothly.
