Electronic cigarette

Abstract

An electronic cigarette comprising a cylindrical housing ( 1 ), a mouthpiece cover ( 33 ) arranged at one end of the housing, and a bottom cover arranged at the other end of the housing, where the bottom cover and the housing are integrally formed. The housing has arranged therein a liquid storage component ( 37 ), an atomizer ( 21 ), and a storage power supply ( 36 ). The housing also has arranged therein a liquid partitioning component ( 31 ). The liquid storage component is accommodated and fixed within a closed space defined and formed jointly by the mouthpiece cover, a portion of the housing, and the liquid partitioning component. The liquid storage component has arranged on the inner wall thereof a conduit ( 35 ) used for supporting the liquid storage component. The conduit is in communication respectively with the mouthpiece cover and with the liquid partitioning component. The atomizer is supported and fixed on the conduit. This electronic cigarette is capable of preventing the bottom cover from falling off of the housing, also is structurally simple, and is easy and convenient to assemble and disassemble.

What is claimed is: 
     
         1 . An electronic cigarette, comprising:
 a cylindrical housing one end of the housing disposing a mouthpiece cover for users smoking, and the other end of the housing disposing a bottom cover;   wherein the bottom cover and the housing are integrally formed, the housing disposes a liquid-storage member for storing e-liquid, an atomizer used to vaporize e-liquid to aerosol and a battery, the housing further disposes a liquid-isolating member, the liquid-storage member is accommodated and fixed in an enclosed place jointly defined by the mouthpiece cover, a portion of the housing and the liquid-isolating member, an inner wall of the liquid-storage member disposes a catheter operable to support the liquid-storage member, the catheter communicates with the mouthpiece cover and the liquid-isolating member respectively, the atomizer is supported and fixed on the catheter.   
     
     
         2 . According to the electronic cigarette in  claim 1 , wherein the atomizer comprises a heating wire and a liquid-guiding member supporting the heating wire; the heating wire works under the control of a control board disposed in the housing, and the heating wire winds on the liquid-guiding member; a positive and a negative electrodes of the heating wire extend out of the liquid-isolating member and connect to corresponding electrodes on the control board. 
     
     
         3 . According to the electronic cigarette in  claim 1 , wherein the catheter is a hollow pipe with a through hole; the catheter defines a slot through a pipe wall thereof and operable to support and fix the liquid-guiding member; the liquid-guiding member is across the catheter and two ends of the light-guiding member respectively pass through the slot and abut with the liquid-storage member to absorb e-liquid for the heating wire atomizing. 
     
     
         4 . According to the electronic cigarette in  claim 3 , wherein a central portion of the mouthpiece cover and a central portion of the liquid-isolating member all define air vents; the through hole of the catheter communicates with the air vent of the mouthpiece cover and the air vent of the liquid-isolating member respectively. 
     
     
         5 . According to the electronic cigarette in  claim 1 , wherein the liquid-storage member is a hollow cylindrical structure, being sheathed on the outside of the catheter and mutually tensions with an outer wall of the catheter to be supported; two ends of the liquid-storage member abut with the mouthpiece cover and the liquid-isolating member respectively, and an inner sidewall of the liquid-storage member abuts with the liquid-guiding member. 
     
     
         6 . According to the electronic cigarette in  claim 1 , wherein the mouthpiece cover is cylindrical, and a central portion of the mouthpiece cover disposes an infixing column for mutually infixing with the catheter and an annular cavity operable to accommodate the catheter. 
     
     
         7 . According to the electronic cigarette in  claim 1 , wherein a sidewall of one end of the mouthpiece cover further disposes a limit flange radially extending outwardly and used to fit with the housing. 
     
     
         8 . According to the electronic cigarette in  claim 1 , wherein the liquid-isolating member includes a seat body fitting with an inner wall of the housing; the seat body is tensioningly fixed on the inner wall of the housing by using an outer sidewall thereof and a tensioning ring formed on the outer sidewall; a central portion of the seat body axially extends outwardly and forms an infixing column operable to infix with the catheter, a central portion of the liquid-isolating member defines an air vent axially through the infixing column and the seat body. 
     
     
         9 . According to the electronic cigarette in  claim 8 , wherein a sidewall of the seat body forms a tensioning ring thereon, which is integrally formed with the seat body. 
     
     
         10 . According to the electronic cigarette in  claim 8 , wherein on the seat body also defines a threading hole locating at the outside of the infixing column and axially through the seat body. 
     
     
         11 . According to the electronic cigarette in  claim 1  to  claim 10 , wherein the electronic cigarette is an integrated electronic cigarette, the housing is an integral housing. 
     
     
         12 . According to the electronic cigarette in  claim 11 , wherein an outer shell of the housing further disposes at least one layer of soft paste layer for wrapping the housing. 
     
     
         13 . According to the electronic cigarette in  claim 11 , wherein the housing is made of any one of the following materials such as metal, plastic, wood or paper material.
