Abstract: A cartridge of an electronic cigarette includes an oil reserving pipe, an oil obstructing plug and a heating assembly. The oil reserving pipe has an inner space for reserving a tobacco oil. The oil obstructing plug is arranged at an end of the oil reserving pipe and has an oil hole in communication with the inner space. The heating assembly is arranged under the oil obstructing plug and configured for heating and atomizing the tobacco oil penetrating through the oil hole. An atomizing device using the cartridge, and an electronic device using the atomizing device are also provided.

Abstract: An atomizing device of electronic cigarette is provided. The atomizing device includes an atomizing sleeve, a liquid reserving member and a heating coil fixed in the atomizing device, a mouthpiece, a screw sleeve, an electrode ring fixed in the screw sleeve, an insulted ring arranged between the screw sleeve and the electrode ring. The mouthpiece and the screw sleeve are respectively engaged to two ends of the atomizing sleeve tightly, and each of two ends of the heating coil respectively connects to the screw sleeve and the electrode ring. The liquid reserving member includes at least two layers with different densities. An electronic cigarette included the atomizing device is also disclosed.

Abstract: An atomizing device of an electronic cigarette includes an atomizing sleeve, an air pipe located in the atomizing sleeve, a heating assembly arranged on the air pipe, a heating assembly fixing base fixing and supporting the heating assembly, a metallic sleeve supporting the heating assembly fixing base, and a sealing cover. The sealing cover and the heating assembly fixing base are respectively located at two opposite ends of the air pipe. The atomizing sleeve, the air pipe, the sealing cover, the heating assembly fixing base, and the metallic sleeve cooperatively define a sealed tobacco solution reserving space without a reservoir cotton received therein. An electronic cigarette using the atomizing device is also provided.
