BACKGROUND

The disclosure relates to an electronic cigarette.

Conventionally, the e-liquid filling hole of the electronic cigarettes is directly disposed on the wall surface of the atomizer, and the c-liquid filling hole is not properly sealed, so that the e-liquid tends to leak when replacing the atomizer.

SUMMARY

The disclosure provides an electronic cigarette comprising a mouthpiece assembly, an atomization assembly, and a base assembly; the mouthpiece assembly and the base assembly are disposed on two ends of the atomization assembly, respectively.

The mouthpiece assembly comprises a mouthpiece; a mouthpiece base; a movable cover; and a slidable block. The atomization assembly comprises a seal gasket; a first permanent seat; a first seal ring; a glass tube; a second seal ring; an elastic sealing device comprising a connection bolt, a seal sleeve, a spring, and a second permanent seat; and an atomizer.

The base assembly comprises an airflow regulation ring; a fixed ring; a joint; an insulation ring; and a base.

The mouthpiece base is connected to the slidable block; the mouthpiece base and the slidable block are disposed on two sides of the movable cover, respectively; the mouthpiece is in threaded connection to the mouthpiece base.

The seal gasket is disposed on the first permanent seat; the first permanent seat comprises a first annular groove and the first seal ring is embedded in the first annular groove; the seal gasket comprises an e-liquid filling hole covered by the movable cover; the movable cover is movable with respect to the seal gasket to cover or expose the e-liquid filling hole; the seal sleeve and the spring encircle the connection bolt, and the seal sleeve is disposed between the spring and the connection bolt; the connection bolt encircled by the seal sleeve and the spring is directly connected to the second permanent seat; the second permanent seat comprises a second annular groove and the second seal ring is disposed in the second annular groove; the glass tube is disposed on the second permanent seat; two ends of the glass tube are in threaded connection to the first permanent seat and the second permanent seat, respectively; the second permanent seat comprises a chamber and the atomizer is disposed in the chamber; the slidable block comprises a convex edge and the first permanent seat comprises an orbital groove; the convex edge matches the orbital groove to fix the slidable block on the first permanent seat.

The joint is encompassed by the insulation ring; the joint and the insulation ring are disposed on the base; the base comprises a flange and the fixed ring encircles the flange; the airflow regulation ring is disposed on the base; and the base is in threaded connection to the second permanent seat.

DETAILED DESCRIPTION

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.

As shown inFIGS. 1-6, an electronic cigarette comprises a mouthpiece assembly A, an atomization assembly B, and a base assembly C. The mouthpiece assembly and the base assembly are disposed on two ends of the atomization assembly, respectively.

The mouthpiece assembly A comprises a mouthpiece1; a mouthpiece base2; a movable cover3; and a slidable block4. The mouthpiece base2is connected to the slidable block4; the mouthpiece base2and the slidable block4are disposed on two sides of the movable cover3, respectively; the mouthpiece1is in threaded connection to the mouthpiece base2.

The atomization assembly B comprises a seal gasket5; a first permanent seat6; a first seal ring7; a glass tube8; a second seal ring9; an elastic sealing device comprising a connection bolt10, a seal sleeve11, a spring12, and a second permanent seat13; and an atomizer14.

The seal gasket5is disposed on the first permanent seat6; the first permanent seat6comprises a first annular groove and the first seal ring7is embedded in the first annular groove; the seal sleeve11and the spring12encircle the connection bolt10, and the seal sleeve H is disposed between the spring12and the connection bolt10; the connection bolt10encircled by the seal sleeve11and the spring12is directly connected to the second permanent seat13; the second permanent seat13comprises a second annular groove and the second seal ring9is disposed in the second annular groove; the glass tube8is disposed on the second permanent seat13; two ends of the glass tube8are in threaded connection to the first permanent seat6and the second permanent seat13, respectively; the second permanent seat13comprises a chamber and the atomizer14is disposed in the chamber; the slidable block4comprises a convex edge and the first permanent seat6comprises an orbital groove; the convex edge matches the orbital groove to fix the slidable block4on the first permanent seat6.

When the atomizer14is inserted into the chamber of the second permanent seat13, the spring12is stressed to push away the seal sleeve11, so that the e-liquid inlet of the second permanent seat13is exposed, and the e-liquid enters into the atomizer14. When the atomizer14is withdrawn from the second permanent seat13, the spring12resets, and the seal sleeve11returns to its original position to block the e-liquid thereby preventing the leakage of the e-liquid.

The mouthpiece assembly is disposed on the atomization assembly. The convex edge of the slidable block4of the mouthpiece assembly is embedded into the orbital groove of the first permanent seat6to fix the mouthpiece assembly on the atomization assembly. The seal gasket5comprises an e-liquid filling hole covered by the movable cover3. The movable cover3is movable with respect to the seal gasket5. When the movable cover3is lifted, the e-liquid filling hole of the seal gasket5is exposed and the e-liquid can be injected to the atomizer.

The base assembly C comprises an airflow regulation ring15; a fixed ring16; a joint17; an insulation ring18; and a base19. The joint17is encompassed by the insulation ring18; the joint17and the insulation ring18are disposed on the base19; the base19comprises a flange and the fixed ring16encircles the flange; the airflow regulation ring15is disposed on the base19; and the base19is in threaded connection to the second permanent seat13.
