The invention relates to a temperature-lowering filter rod and a heating non-burning cigarette, the cooling nozzle comprises a cooling section, the cooling section comprises a carrier on which a temperature-lowering material is applied, and the carrier is arranged in the cooling section to form a plurality of a passage through the cooling section; the temperature reducing material is a crystalline water compound, the crystalline water compound is ferrous sulfate heptahydrate, potassium aluminum sulfate dodecahydrate, disodium hydrogen phosphate dodecahydrate, magnesium sulfate heptahydrate, sulfuric acid pentahydrate At least one of copper, sodium sulfate decahydrate; preferably, the carrier is paper. The invention effectively reduces the inlet temperature of the flue gas, and the reduction range is up to 10 ° C or more; the use of the crystallization hydrate to absorb the heat to release the crystallization water characteristic can effectively reduce the temperature of the flue gas of the first three mouths of the non-burning cigarette. |
