         5 . The electronic cigarette of  claim 4 , wherein both the mouthpiece cover and the liquid isolation component define vent holes in center, and the through hole of the conduit is respectively communicated with both the vent hole of the mouthpiece cover and the vent hole of the liquid isolation component. 
     
     
         6 . The electronic cigarette of  claim 2 , wherein the liquid storage component is a hollow cylinder, is sleeved on outer wall of the conduit and is tightly engaged with the outer wall of the conduit as so to be supported; both ends of the liquid storage component respectively abut against the mouthpiece cover and the liquid isolation component, and inner wall of the liquid storage component contacts the liquid guiding component. 
     
     
         7 . The electronic cigarette of  claim 2 , wherein the mouthpiece cover at its center forms a column for connecting the conduit. 
     
     
         8 . The electronic cigarette of  claim 1 , wherein there are two soft layers. 
     
     
         9 . The electronic cigarette of  claim 1 , wherein the soft layer is made from any one insulation material selected from Polybutylene terephthalate plastic, ethylene-vinylacetate copolymer, or polyvinyl chloride. 
     
     
         10 . The electronic cigarette of  claim 2 , wherein the electronic cigarette is a separated type of electronic cigarette, and comprises an inhaling rod and a power rod both of which are interconnected; the inhaling rod comprises a cylindrical inhaling tube used as a shell of the inhaling rod; one end of the inhaling tube is set with the mouthpiece cover, the other end thereof is set with a first connector for connecting the power rod, the mouthpiece cover is inserted into the inhaling tube; the first connector comprises a first seat and a first pole respectively used as both electrodes of the first connector, the first seat is used as the liquid isolation component; a first insulation sleeve is set between the first seat and the first pole for insulation, the first pole is inserted in center of the first seat by mean of the first insulation sleeve; the first seat, the mouthpiece cover, and a part of the inhaling tube together enclose the closed space for containing the liquid storage component; and the first seat and the mouthpiece cover are oppositely fitted in inner wall of the inhaling tube with a space between the two. 
     
     
         11 . The electronic cigarette of  claim 10 , wherein the first pole defines a through hole at its center, and the first pole is inserted in the conduit and communicated with the conduit. 
     
     
         12 . The electronic cigarette of  claim 10 , wherein the power rod is set with a second connector at its end connecting the inhaling rod for engaging with the first connector; the second connector comprises a second seat and a second pole as two electrodes of the second connector, a second insulation sleeve is set between the second seat and the second pole for insulation; the second pole is inserted in center of the second seat by means of the second insulation sleeve; the second seat and the second pole are respectively connected with the positive and negative poles of the power supply; the first seat and the second seat are threadedly connected whereby the first seat contacts the first seat and the first pole contacts the second pole. 
     
     
         13 . The electronic cigarette of  claim 2 , wherein the electronic cigarette is an integrated type of electronic cigarette, and the outer shell is an integrated shell. 
     
     
         14 . The electronic cigarette of  claim 13 , wherein the electronic cigarette is set with an isolation seat as the liquid isolation component; the isolation seat is tightly fitted in inner wall of the outer shell by its outer sidewall; the isolation seat at its center forms a column for connecting the conduit; and the column at its center also defines an axial vent hole.
