Electronic cigarette

Abstract

An electronic cigarette includes a circuit unit, an oil container, an atomizing unit, and a sealing plug. The circuit unit is coupled to a lower portion of the atomizing unit. The oil container is mounted to the circuit unit and is detachable from the circuit unit. The atomizing unit is received in the oil container and is coupled to the circuit unit. The atomizing unit is detachable from the oil container and the circuit unit. The sealing plug is configured to secure and seal the oil container when the oil container is detached from the circuit unit. Any one of the atomizing unit and the oil container can be changed separately when it is damaged or worn-out, and use cost is also lowered.

1 . An electronic cigarette, comprising:
 a circuit unit, coupling to a lower portion of the atomizing unit;   an oil container, mounted to the circuit unit and being detachable from the circuit unit, the oil container comprising a smoke passage and a container base, the container base defining an atomizing chamber, an oil inlet and an oil outlet, the atomizing chamber located in a top portion of the atomizing chamber, and the oil outlet defined towards an internal portion of the atomizing chamber;   an atomizing unit, received in the oil container to seal the atomizing chamber and coupled to the circuit unit, the atomizing unit being detachable from the oil container and the circuit unit, an oil deflecting hole defined in an upper portion of the atomizing unit and connecting to the oil outlet; and   a sealing plug, configured to secure and seal the oil container when the oil container is detached from the circuit unit.   
     
     
         2 . The electronic cigarette of  claim 1 , where in a container latch is located on the lower portion of the oil container, and the container latch is coupled to the circuit unit. 
     
     
         3 . The electronic cigarette of  claim 2 , where in the container latch is configured to be screwed to the sealing plug. 
     
     
         4 . The electronic cigarette of  claim 1 , where in a retaining protuberance is located on a middle portion of the atomizing unit, and an upper sealing ring and a lower sealing ring are attached to the retaining protuberance at two opposite sides. 
     
     
         5 . The electronic cigarette of  claim 1 , where in the upper portion of the atomizing unit is plugged in the atomizing chamber. 
     
     
         6 . The electronic cigarette of  claim 1 , where in the lower portion of the atomizing unit is plugged in and seals the circuit unit. 
     
     
         7 . The electronic cigarette of  claim 1 , where in when the atomizing unit is detached from the oil container, oil is maintained in the oil container due to balance of the air pressure and surface tension of the oil, and the oil container is self-sealed without leak. 
     
     
         8 . An electronic cigarette, comprising:
 a circuit unit, coupling to a lower portion of the atomizing unit;   an oil container, mounted to the circuit unit and being detachable from the circuit unit, the oil container comprising a smoke passage and a container base, the container base defining an atomizing chamber, an oil inlet and an oil outlet, the atomizing chamber located in a top portion of the atomizing chamber, and the oil outlet defined towards an internal portion of the atomizing chamber; and   an atomizing unit, received in the oil container to seal the atomizing chamber and coupled to the circuit unit, the atomizing unit being detachable from the oil container and the circuit unit, an oil deflecting hole defined in an upper portion of the atomizing unit and connecting to the oil outlet.   
     
     
         9 . The electronic cigarette of  claim 8 , where in the electronic cigarette further comprises a sealing plug to secure and seal the oil container when the oil container is detached from the circuit unit. 
     
     
         10 . The electronic cigarette of  claim 9 , wherein a container latch is located on the lower portion of the oil container, and the container latch is coupled to the circuit unit. 
     
     
         11 . The electronic cigarette of  claim 9 , where in the container latch is configured to be screwed to the sealing plug. 
     
     
         12 . The electronic cigarette of  claim 8 , wherein a retaining protuberance is located on a middle portion of the atomizing unit, and an upper sealing ring and a lower sealing ring are attached to the retaining protuberance at two opposite sides. 
     
     
         13 . The electronic cigarette of  claim 8 , where in the upper portion of the atomizing unit is plugged in the atomizing chamber. 
     
     
         14 . The electronic cigarette of  claim 8 , where in the lower portion of the atomizing unit is plugged in and seals the circuit unit. 
     
     
         15 . The electronic cigarette of  claim 8 , where in when the atomizing unit is detached from the oil container, oil is maintained in the oil container due to balance of the air pressure and surface tension of the oil, and the oil container is self-sealed without leak.
