The invention discloses a novel ceramic-core disposable electronic cigarette. The novel ceramic-core disposable electronic cigarette comprises a stainless steel tube, a pluggable suction nozzle, an E-liquid storage chamber and a battery; the pluggable suction nozzle is inserted in one end of the stainless steel tube, and the end, located in the stainless steel tube, of the pluggable suction nozzleis sleeved with a suction nozzle sealing ring; an anti-leakage silicone piece is fixedly installed at the portion, on the other side of the suction nozzle sealing ring, in the stainless steel tube; an atomizing ceramic cup is fixedly installed on the side, away from the pluggable suction nozzle, of the anti-leakage silicone piece, a heating wire is uniformly wound around the outside of the atomizing ceramic cup, the atomizing ceramic cup is inserted in the E-liquid storage chamber, and an insulating silicone plug is fixedly installed at the other end of the E-liquid storage chamber. In the novel ceramic-core disposable electronic cigarette, a traditional intermediate gas circuit structure is changed; when smoke is generated by atomization during work of the electronic cigarette, the smokepasses by the periphery of the electronic cigarette and then is collected before entering the mouth, a curved smoke channel is formed, the problem of E-liquid splashing is completely solved, and a user can have a good experience and a high sense of safety.
