Electronic cigarette vaporizer

Abstract

An electronic cigarette vaporizer comprises an outer tube, a mouthpiece member arranged at an end of the outer tube, and a vaporizing member arranged inside the outer tube. The vaporizing member comprises a two-part tube body which is integrally-formed and consists of a vapor tube located at an upper position and having a smaller diameter and a vaporizing tube located at a lower position and having a greater diameter which are connected with each other. A storage chamber for storing vapor substrate is formed between an outer wall of the two-part tube body and an inner wall of the outer tube. A tube-shaped vaporizing core for heating and vaporizing the vapor substrate is sleeved inside the vaporizing tube. A wall portion of the vaporizing tube is provided with a substrate through-hole. An upper end of a wall portion of the vapor tube is provided with a vent aperture.

1 . An electronic cigarette vaporizer, comprising an outer tube, a mouthpiece member arranged at an end of the outer tube, a connecting member arranged at another end of the outer tube, and a vaporizing member arranged inside the outer tube, wherein the mouthpiece member comprises a mouthpiece housing having a mouthpiece end and a connecting end, a vapor passage extending through the mouthpiece end and the connecting end is formed in center of the mouthpiece housing, the vaporizing member comprises a two-part tube body which is integrally-formed and consists of a vapor tube located at an upper position and having a smaller diameter and a vaporizing tube located at a lower position and having a greater diameter, the vapor tube and the vaporizing tube are connected with each other, a storage chamber for storing vapor substrate is formed between an outer wall of the two-part tube body and an inner wall of the outer tube, a tube-shaped vaporizing core for heating and vaporizing the vapor substrate is sleeved inside the vaporizing tube, a wall portion of the vaporizing tube is provided with a substrate through-hole, an upper end of a wall portion of the vapor tube is provided with a vent aperture, during assembly of the mouthpiece member, the connecting end fits tightly between the outer tube and the vapor tube to compress air, and the vent aperture allows the compressed air to evacuate, avoiding a leakage of the vapor substrate caused by the compressed air. 
     
     
         2 . The electronic cigarette vaporizer according to  claim 1 , wherein the two-part tube body is integrally-formed and made of a material which is stainless and corrosion resistant and readily conducts heat, excessive heat energy generated during heating of the vapor substrate by the tube-shaped vaporizing core is quickly transferred to the vapor substrate disposed in the storage chamber by the two-part tube body, to preheat the vapor substrate to improve fluidity. 
     
     
         3 . The electronic cigarette vaporizer according to  claim 1 , wherein the vapor substrate comprises cigarette liquid, tobacco tar having high viscosity, or waxy solid formed by solidification of tobacco tar, which produce vapor when being heated. 
     
     
         4 . The electronic cigarette vaporizer according to  claim 1 , wherein the tube-shaped vaporizing core comprises a porous ceramic tube, a porous quartz tube, or a porous carbon fiber tube, with a heating element being embedded inside. 
     
     
         5 . The electronic cigarette vaporizer according to  claim 1 , wherein between an inner wall of the vaporizing tube and the tube-shaped vaporizing core, a liquid-permeable layer is further provided. 
     
     
         6 . The electronic cigarette vaporizer according to  claim 5 , wherein the liquid-permeable layer is made of non-woven fabric, carbon fiber, quartz fiber, or organic cotton. 
     
     
         7 . The electronic cigarette vaporizer according to  claim 1 , wherein the mouthpiece member further comprises a mouthpiece sealing ring, a wall portion of a connecting end of the mouthpiece housing is provided with a groove which extends axially and has an annular shape, and the mouthpiece sealing ring is disposed in the groove and tightly abuts against an outer wall of the vapor tube. 
     
     
         8 . The electronic cigarette vaporizer according to  claim 7 , wherein a metallic ring is further disposed between an outer wall of the mouthpiece sealing ring and the mouthpiece housing. 
     
     
         9 . The electronic cigarette vaporizer according to  claim 1 , wherein the connecting member comprises a base provided with a through-hole extending axially, an upper portion of the base is located between the outer tube and the vaporizing tube, a lower portion of the base has an outer wall having a reduced outer diameter, and the outer wall is provided with connecting threads for connecting a battery rod to form an electronic cigarette by the electronic cigarette vaporizer and the battery rod, and a positive electrode is disposed in the through-hole of the base. 
     
     
         10 . The electronic cigarette vaporizer according to  claim 1 , wherein two ends of the outer tube are respectively connected with a metal sleeve.
