LIQUID CHAMBER ASSEMBLY AND ATOMIZER FOR ELECTRONIC CIGARETTE

The present invention provided a liquid cartridge assembly (1) for an electronic cigarette and an atomizer. The liquid cartridge assembly (1) comprises a liquid cartridge housing (11) and a first plug (12) fastened to each other, a liquid cartridge (15) is disposed between the liquid cartridge housing (11) and the first plug (12), the first plug (12) is provided with a through groove (122) communicated with the liquid cartridge (15), two ends of liquid guide cotton (14) pass through the through groove (122) to extend into the liquid cartridge (15), a plurality of second protrusions (1221) for squeezing the liquid guide cotton (14) are disposed in the through groove (122), and an air passing gap (1222) for supplementing air to the liquid cartridge (15) is formed between adjacent second protrusions (1221). Not only can the liquid guide cotton (14) be prevented from falling off the through groove (122), but when smoking, some air in an atomization cavity can easily enter the liquid cartridge (15) from the air passing gaps (1222), so that the liquid supply speed of the liquid cartridge (15) is increased, to prevent the phenomenon of dry burning caused by an excessively slow liquid guide speed.
