Electronic cigarette structure

Abstract

An electronic cigarette structure includes a casing having an e-liquid chamber and an opening in communication therewith, a cotton body, an airflow duct, an atomizer, and a cover on the opening and sealing the components above in the chamber. The cotton body is disposed in the e-liquid chamber for absorbing the e-liquid. The airflow duct is hollow and combined into the cotton body in the e-liquid chamber. The atomizer is disposed in the through hole of the airflow duct, so as to thermally atomize the e-liquid for producing smoke. The cover has a via hole in communication with the through hole, so that the smoke generated in the through hole is sucked out from the via hole. Thus, the tar separation is avoided, and the e-liquid is prevented from leaking.

What is claimed is: 
     
         1 . An electronic cigarette structure, comprising:
 a casing comprising an e-liquid chamber and an opening in communication with the e-liquid chamber;   a cotton body disposed in the e-liquid chamber for absorbing the e-liquid;   an airflow duct disposed in the cotton body in the e-liquid chamber, the airflow duct being hollow and comprising a through hole;   an atomizer disposed in the through hole of the airflow duct; the e-liquid absorbed by the cotton body being conveyed to the through hole, so as to be heated and atomized into smoke in the through hole by the atomizer; and   a cover disposed on the opening and covering the cotton body, the airflow duct, and the atomizer in the e-liquid chamber; the cover comprising a via hole in communication with the through hole, so that the smoke in the through hole is sucked out from the via hole.   
     
     
         2 . The electronic cigarette structure of  claim 1 , wherein the casing comprises an outer shell and an inner shell; the e-liquid chamber is disposed on the inner shell; the opening in communication with the e-liquid chamber is disposed on one end of the inner shell; the inner shell is contained in the outer shell. 
     
     
         3 . The electronic cigarette structure of  claim 2 , wherein the inner shell comprises a housing recess, which is disposed on a position different from the e-liquid chamber and in communication with the e-liquid chamber, with a power supplier disposed in the housing recess; the power supplier is electrically connected with the atomizer, so as to provide a power needed for the atomizer to heat the e-liquid; the power supplier controls a heating operation of the atomizer. 
     
     
         4 . The electronic cigarette structure of  claim 3 , wherein the power supplier comprises a battery and a rectifier that are electrically connected. 
     
     
         5 . The electronic cigarette structure of  claim 4 , wherein the atomizer is a heating wire, which is wired to the rectifier and electrically connected with the battery; the atomizer wraps a vape cotton in the through hole; the e-liquid conveyed into the through hole and absorbed by the vape cotton; when the atomizer heats the e-liquid absorbed by the vape cotton, the e-liquid is atomized into the smoke. 
     
     
         6 . The electronic cigarette structure of  claim 3 , wherein the outer shell is hollow and comprises a placement bore; two ends of the outer shell are open to form a first end bore and a second end bore, respectively; the first end bore has a nozzle, and the second end bore has an end cap; the end cap has an intake bore in communication with the housing recess; the nozzle and the end cap position the inner shell in the outer shell; the nozzle comprises an inhale bore facing the via hole, such that the smoke is sucked out from the intake bore. 
     
     
         7 . The electronic cigarette structure of  claim 6 , wherein the nozzle comprises a filter material, such that the smoke passes through the filter material before being sucked out from the intake bore. 
     
     
         8 . The electronic cigarette structure of  claim 2 , wherein the inner shell is formed of a transparent plastic material, and the airflow duct is formed of a fiberglass material. 
     
     
         9 . The electronic cigarette structure of  claim 1 , wherein the cover is formed of a silica gel material. The cover comprises a pillar inserted into the through hole; the via hole passes through the pillar to be in communication with the through hole. 
     
     
         10 . The electronic cigarette structure of  claim 1 , wherein the cotton body is integrally formed, with an insertion bore formed at a center thereof; the airflow duct is inserted into the insertion bore to be combined in the cotton body.
