Electronic cigarette

Abstract

An electronic cigarette includes an atomizing body and an atomizing core disposed inside the atomizing body to absorb and atomize e-liquid. The atomizing body includes a first e-liquid chamber, a second e-liquid chamber, and an e-liquid delivery section. The e-liquid delivery section is disposed between the first e-liquid chamber and the second e-liquid chamber. The atomizing core is disposed within the first e-liquid chamber to absorb and atomize the e-liquid stored in the first e-liquid chamber. The e-liquid delivery section includes a sealing component movable between a first position and a second position. The first position is where the sealing component seals the e-liquid delivery section and thus isolates the first e-liquid chamber and the second e-liquid chamber. The second position is where the sealing component is disconnected from the e-liquid delivery section, allowing the first e-liquid chamber and the second e-liquid chamber to communicate with each other.

What is claimed is: 
     
         1 . An electronic cigarette, comprising:
 1) an atomizing body; and   2) an atomizing core disposed inside the atomizing body to absorb and atomize e-liquid;   
       wherein,
 the atomizing body comprises a first e-liquid chamber, a second e-liquid chamber, and an e-liquid delivery section; the e-liquid delivery section is disposed between the first e-liquid chamber and the second e-liquid chamber, so that the first e-liquid chamber is in fluid communication with the second e-liquid chamber; and the atomizing core is disposed within the first e-liquid chamber to absorb and atomize the e-liquid stored in the first e-liquid chamber; and 
 the e-liquid delivery section comprises a sealing component movable between a first position and a second position; the first position is where the sealing component seals the e-liquid delivery section and thus isolates the first e-liquid chamber and the second e-liquid chamber; and the second position is where the sealing component is disconnected from the e-liquid delivery section, allowing the first e-liquid chamber and the second e-liquid chamber to communicate with each other. 
 
     
     
         2 . The electronic cigarette of  claim 1 , wherein no e-liquid is stored in the first e-liquid chamber, and the e-liquid is stored in the second e-liquid chamber. 
     
     
         3 . The electronic cigarette of  claim 1 , wherein the electronic cigarette further comprises a push-pull rod disposed on the sealing component to regulate the motion of the sealing component. 
     
     
         4 . The electronic cigarette of  claim 3 , wherein the push-pull rod comprises a rod body and a cap; and the cap is disposed on one end of the rod body away from the sealing component. 
     
     
         5 . The electronic cigarette of  claim 4 , wherein the electronic cigarette further comprises an elastic element sleeving the push-pull rod to reset the sealing component; or the push-pull rod is deformable under an external force and resilient when the external force is removed. 
     
     
         6 . The electronic cigarette of  claim 5 , wherein the elastic element is disposed around the push-pull rod and is disposed between the cap and the atomizing body; one end of the elastic element is fixed to the cap, and the other end of the elastic element is fixed to the atomizing body. 
     
     
         7 . The electronic cigarette of  claim 6 , wherein the atomizing body further comprises an elastic groove used to receive the elastic element; and the elastic groove has a width of 1 to 1.5 times a width of the elastic element. 
     
     
         8 . The electronic cigarette of  claim 7 , wherein the atomizing body further comprises an installation groove serving as a guide for the rod body into an interior cavity of the atomizing body; the installation groove is coaxial with the e-liquid delivery section; and a projection of the installation groove towards the cap is located within the contour of the cap and surrounds a contour of the rod body. 
     
     
         9 . The electronic cigarette of  claim 8 , wherein the electronic cigarette further comprises a positioning block disposed between the atomizing body and the cap; the positioning block is used to restrict the movement of the push-pull rod; and the positioning block is detachably connected to the cap. 
     
     
         10 . The electronic cigarette of  claim 9 , wherein the sealing component comprises a sealing cap disposed at one end of the push-pull rod; the sealing cap comprises a proximal end near the e-liquid delivery section, and the proximal end of the sealing cap comprises an extending portion; when reaching the first position, the sealing cap is located within the second e-liquid chamber, and the extending portion abuts against an end face of a portion of the atomizing body that defines the e-liquid delivery section; and the e-liquid delivery section directly aligns with the sealing cap. 
     
     
         11 . The electronic cigarette of  claim 10 , wherein a volume of the second e-liquid chamber is 2-10 times that of the first e-liquid chamber. 
     
     
         12 . The electronic cigarette of  claim 11 , wherein the first e-liquid chamber has a volume of 1-3 mL, and the second e-liquid chamber has a volume of 8-15 mL. 
     
     
         13 . The electronic cigarette of  claim 12 , wherein the atomizing core comprises a smoke guide tube and a heating element; the heating element is disposed within the smoke guide tube; the smoke guide tube comprises an e-liquid inlet through which the e-liquid flows from the first e-liquid chamber into the smoke guide tube; one end of the atomizing body comprises a smoking port through which a user inhales the smoke; a smoke channel is formed between the smoking port and the first chamber; the smoke channel communicates with the smoke guide tube, so that the smoke produced by the heating element is discharged outside of the atomizing body; and the electronic cigarette further comprises a mouthpiece cover disposed on the smoking port and detachably connected to the atomizing body. 
     
     
         14 . The electronic cigarette of  claim 13 , wherein the electronic cigarette further comprises a bracket used to separate the interior cavity of the atomizing body into the first e-liquid chamber, the second e-liquid chamber, and a battery compartment; the second e-liquid chamber and the battery compartment are arranged side by side in a transverse direction; the second e-liquid chamber and the battery compartment are disposed longitudinally adjacent to the first e-liquid chamber; and the atomizing core is disposed inside the first e-liquid chamber and within an projection area of the battery compartment. 
     
     
         15 . The electronic cigarette of  claim 14 , wherein the bracket comprises a first sealing part and a second sealing part; the first sealing part is disposed inside the first e-liquid chamber; and the second sealing part is disposed on one side of the second e-liquid chamber;
