[0008] To further illustrate, embodiments detailing an electronic cigarette are described below. It should be noted that the following embodiments are intended to describe and not to limit the disclosure.
[0009] As shown in FIGS. 1-5, the disclosure provides an electronic cigarette comprising an atomization assembly A and a battery assembly B. The atomization assembly is directly connected to the battery assembly. The atomization assembly A comprises a mouthpiece 1, a glass tube 15, a first seal ring 2 sealing the glass tube, an atomizer comprising a head 4 and a base 8, a second seal ring 3 sealing the head, a vent tube 5, a third seal ring 6 sealing the base of the atomizer, and an atomization core, the atomization core comprising a silica seal 9, a silica sleeve comprising a vent 10, a ceramic core 11, a pedestal 12, a first insulation ring 13, a heating tube 7, and a joint 14. The first seal ring 2 is disposed in the mouthpiece 1; the second seal ring 3 is sheathed on the head 4; the head 4 is disposed on the vent tube 5; the vent tube 5 is disposed on the base 8; the third seal ring 6 is sheathed on the base 8; the ceramic core 11 and the silica sleeve comprising a vent 10 are disposed on the pedestal 12; the silica seal 9 is disposed on the ceramic core 11; the first insulation ring 13 is disposed in the pedestal 12; the heating tube 7 is disposed on the joint 14; the joint 14 is embedded in the first insulation ring 13; the atomization core is embedded in the base 8; the glass tube 15 is sheathed on the base 8, and the mouthpiece 1 is in threaded connection to the head 4.
[0010] Open the mouthpiece 1, the e-liquid can be injected in the atomizer through the opening of the glass tube 15. Thereafter, the e-liquid penetrates from the inlet of the base 8 of the atomizer into the ceramic core 11. During the penetration, the e-liquid will produce bubbles. The bubbles can release from the gear grooves or knurling grooves thus preventing the blockage of the inlet of the e-liquid.
[0011] The heating tube 7 of the atomization assembly is directly connected to the joint 14, which means the heating tube is indirectly connected to the positive pole of the ceramic core 11, and communicates with the mouthpiece 1 and the pneumatic switch 23 of the battery assembly. During smoking, the thermal vapor flow can enter the heating tube to drive the pneumatic switch to work and heat the ceramic core, so that the e-liquid in the atomization assembly is heated to a free state, thus preventing the blockage of the conveying pipe by the condensed e-liquid.
