Electronic cicarette

Abstract

An electronic cigarette includes a rod having an atomization device and a battery assembly, wherein the electronic cigarette further includes a jacket, the jacket is arranged on an outer surface of the rod, and an outer surface of the jacket is provided with a friction portion. When using the electronic cigarette, due to the friction portion, fingers of a user may contact the friction portion, which may increase the friction between the fingers and the rod, thereby effectively preventing the electronic cigarette from falling off from the fingers in use.

         3 . The electronic cigarette according to  claim 1 , wherein the rod comprises a first main body and a second main body, the first main body and the second main body are configured to be detachably connected, the atomization device is arranged in the first main body, and the battery assembly is arranged in the second main body. 
     
     
         4 . The electronic cigarette according to  claim 3 , wherein the jacket is arranged on the second main body, and the friction portion is arranged at an end of the jacket near the first main body. 
     
     
         5 . The electronic cigarette according to  claim 2 , wherein the friction portion is spherical convex portions. 
     
     
         6 . The electronic cigarette according to  claim 2 , wherein the friction portion is annular convex portions distributed in a spiral shape. 
     
     
         7 . The electronic cigarette according to  claim 2 , wherein the friction portion is swingable swing ball convex portions. 
     
     
         8 . The electronic cigarette according to  claim 2 , wherein the friction portion is spherical convex portions. 
     
     
         9 . The electronic cigarette according to  claim 1 , wherein the jacket is a rubber jacket. 
     
     
         10 . The electronic cigarette according to  claim 1 , wherein the jacket is a jacket made of ethylene vinyl acetate copolymer material. 
     
     
         11 . The electronic cigarette according to  claim 4 , wherein the friction portion is spherical convex portions. 
     
     
         12 . The electronic cigarette according to  claim 4 , wherein the friction portion is annular convex portions distributed in a spiral shape. 
     
     
         13 . The electronic cigarette according to  claim 4 , wherein the friction portion is swingable swing ball convex portions. 
     
     
         14 . The electronic cigarette according to  claim 4 , wherein the friction portion is spherical convex portions.
