Electronic cigarette
View Patent ↗An electronic cigarette includes a preheater. The preheater includes an e-liquid tank and a heating wire disposed in the e-liquid tank. In a power-on state, the heating wire produces heat.
1. An electronic cigarette, comprising a preheater and a ceramic core; wherein:
the preheater comprises an e-liquid tank and a heating wire disposed in the e-liquid tank; in a power-on state, the heating wire produces heat;
the ceramic core is configured to atomize e-liquid flowing through the ceramic core in the power-on state; and
the preheater further comprises an air duct and a contact pin; the air duct and the heating wire are disposed in the contact pin; the contact pin is disposed in the e-liquid tank; and air of the e-liquid tank flows in the air duct.
2. The electronic cigarette of claim 1 , wherein the preheater further comprises a pinhead, a silicone gasket, and a polytetrafluoroethylene tube; the polytetrafluoroethylene tube is disposed around the heating wire for insulation; the pinhead is disposed on the contact pin and communicates with the e-liquid tank; and the silicone gasket is disposed around the air duct.
3. The electronic cigarette of claim 2 , wherein the e-liquid tank comprises glass.
4. The electronic cigarette of claim 3 , further comprising a silicone base and an atomization base; wherein the ceramic core is fixed in the silicone base, and the silicone base is fixed in the atomization base.
5. The electronic cigarette of claim 4 , wherein the ceramic core is replaced by glass, quartz, crystal, agate, jade, or mica and is transversely or longitudinally rotatably fixed on the silicone base.
6. The electronic cigarette of claim 5 , further comprising an outer insulation ring, an outer joint, an inner insulation ring, an inner joint, wherein the outer insulation ring is disposed on a bottom end of the atomization base to electrically insulate positive and negative terminals of the heating wire; the outer joint is disposed in the outer insulation ring and contacts the positive and negative terminals of the heating wire; the inner insulation ring is disposed in the outer joint to electrically insulate positive and negative terminals of the ceramic core; and the inner joint is disposed in the inner insulation ring and contacts the positive and negative terminals of the ceramic core.
7. The electronic cigarette of claim 6 , further comprising a battery assembly, wherein the battery assembly comprises a control unit, a power button, and a warm-up button; the control unit is configured to control preheating and atomization of e-liquid through pressing the power button or the warm-up button.
8. The electronic cigarette of claim 7 , wherein the control unit further comprises an igniting plate and a control panel; the power button is disposed on the igniting plate; the warm-up button is disposed on the control panel; the ceramic core is controlled by a circuit of the igniting plate; and the heating wire is controlled by a circuit of the control panel.
