Liquid-air separation electronic cigarette

Abstract

Provided is a liquid-air separation electronic cigarette, comprising a liquid storage tank, a tank base, and an atomizer core, wherein the liquid storage tank is provided with a mouthpiece groove at its top, which moves up and down along a height direction of the liquid storage tank, wherein the atomizer core is connected to a lower part of the mouthpiece, a middle part of the atomizer core is provided with a liquid inlet hole, and a lower part of the atomizer core is provided with an air inlet hole, and wherein the tank base is provided with a liquid inlet hole sealing ring and an air inlet hole sealing ring. The atomizer core of the electronic cigarette achieves liquid and air separation, addressing the issue of cigarette liquid leakage, and simultaneously provides a better user experience.

What is claimed is: 
     
         1 . A liquid-air separation electronic cigarette, comprising a liquid storage tank, a tank base, and an atomizer core, wherein the liquid storage tank has a hollow liquid storage cavity, and the tank base is arranged at a bottom of the liquid storage tank to seal a bottom of the liquid storage cavity;
 wherein the liquid storage tank is provided with a mouthpiece groove at its top, and a mouthpiece, which is movable up and down along a height direction of the liquid storage tank, is arranged in the mouthpiece groove;   wherein the atomizer core is connected to a lower part of the mouthpiece, a middle part of the atomizer core is provided with a liquid inlet hole, and a lower part of the atomizer core is provided with an air inlet hole;   wherein a liquid inlet hole sealing ring is arranged above the tank base, and an air inlet hole sealing ring is arranged below the tank base; and   wherein when the mouthpiece is lifted upward, the mouthpiece drives the atomizer core upward to allow the liquid inlet hole to communicate with the liquid storage cavity, and the air inlet hole to communicate with an external atmosphere, and when the mouthpiece is pressed downward, the liquid inlet hole reaches a position aligned with the liquid inlet hole sealing ring for the sealing of the liquid inlet hole, and the air inlet hole reaches a position aligned with the air inlet hole sealing ring for the sealing of the air inlet hole.   
     
     
         2 . The liquid-air separation electronic cigarette according to  claim 1 , wherein the atomizer core comprises a heating wire support and an atomizer core cover sleeved on an upper part of the heating wire support, and wherein the atomizer core cover is provided with the liquid inlet hole, and the heating wire support is provided with the air inlet hole. 
     
     
         3 . The liquid-air separation electronic cigarette according to  claim 2 , wherein the heating wire support has a hollow ignition chamber, in which an atomization mechanism is arranged, and wherein the atomization mechanism includes a heating wire, and a multi-layer cotton and a liquid-conducting cotton wrapped around the heating wire. 
     
     
         4 . The liquid-air separation electronic cigarette according to  claim 3 , wherein the liquid inlet hole and the air inlet hole are in communication with the ignition chamber. 
     
     
         5 . The liquid-air separation electronic cigarette according to  claim 4 , wherein the tank base comprises a tank base cover, and wherein the tank base cover is provided with a through hole, through which the atomizer core passes, and the liquid inlet hole sealing ring is arranged in the through hole. 
     
     
         6 . The liquid-air separation electronic cigarette according to  claim 5 , wherein sides of the tank base cover are surrounded by a silicone gasket, which is used for sealing a connection between the tank base cover and the liquid storage cavity. 
     
     
         7 . The liquid-air separation electronic cigarette according to  claim 5 , wherein the tank base cover is provided with an air inlet hole sealing ring support, in which the air inlet hole sealing ring is arranged. 
     
     
         8 . The liquid-air separation electronic cigarette according to  claim 7 , wherein a liquid filling hole communicated with the liquid storage cavity is provided on a side of the liquid storage tank, a liquid filling silicone plug is installed in the liquid filling hole. 
     
     
         9 . The liquid-air separation electronic cigarette according to  claim 8 , wherein the atomizer core cover has an annular groove at its top side, and an O-ring for sealing is arranged in the annular groove. 
     
     
         10 . The liquid-air separation electronic cigarette according to  claim 9 , wherein a bottom of the heating wire is provided with a PCB board for controlling operation of the heating wire.
