Atomizer and electronic cigarette comprising the same

Abstract

An atomizer includes a housing, a partition wall, a heating core, and an e-liquid accumulation part. The housing includes an e-liquid chamber and a heating chamber. The partition wall is disposed between the e-liquid chamber and the heating chamber to separate the e-liquid chamber and the heating chamber. The partition wall includes at least one e-liquid inlet. The heating core is disposed in the heating chamber and opposite to the at least one e-liquid inlet. The e-liquid accumulation part is disposed in the e-liquid chamber, so that the e-liquid is accumulated and directed to the at least one e-liquid inlet. The e-liquid accumulation part communicates with the heating chamber through the at least one e-liquid inlet.

         2 . The atomizer of  claim 1 , wherein the e-liquid accumulation part comprises a groove and/or a gap; the e-liquid accumulation part and the at least one e-liquid inlet are adjacent to one end of the e-liquid chamber. 
     
     
         3 . The atomizer of  claim 2 , wherein the e-liquid chamber comprises a first section and a second section connected to the first section; the e-liquid accumulation part is disposed in the second section; the first section has a greater radial cross-sectional area than the e-liquid accumulation part. 
     
     
         4 . The atomizer of  claim 3 , wherein the e-liquid chamber is defined by an inner wall of the housing and the partition wall; and the partition wall comprises a protrusion extending horizontally into one end of the e-liquid chamber. 
     
     
         5 . The atomizer of  claim 4 , wherein one end of the protrusion comprises a step structure; the step structure comprises at least one groove functioning as the e-liquid accumulation part; and at least one e-liquid inlet is disposed on the partition wall and opposite to the at least one groove. 
     
     
         6 . The atomizer of  claim 5 , wherein the protrusion is connected to the inner wall of the housing. 
     
     
         7 . The atomizer of  claim 4 , wherein a gap is formed between the protrusion and the inner wall of the housing; the at least one e-liquid inlet is disposed on the partition wall and opposite to the gap. 
     
     
         8 . The atomizer of  claim 4 , wherein the atomizer further comprises an atomizing tube disposed in the housing; the atomizing tube comprises a channel functioning as the heating chamber; the e-liquid chamber is formed between the outer wall of the atomizing tube and the inner wall of the housing; the atomizing tube comprises a sidewall functioning as the partition wall; and the protrusion surrounds the atomizing tube. 
     
     
         9 . The atomizer of  claim 8 , wherein the heating core comprises an e-liquid absorbent element and a heating element; the e-liquid absorbent element is configured to envelop an outer surface of the heating element and seal the at least one e-liquid inlet. 
     
     
         10 . The atomizer of  claim 9 , wherein the atomizer further comprises a mouthpiece for smoking; the mouthpiece is disposed at one end of the housing and aligns with the atomizing tube; the atomizer further comprises a first sealing member disposed between the mouthpiece and the housing to seal one end of the e-liquid chamber; the mouthpiece comprises a smoke channel; one end of the atomizing tube is disposed into the smoke channel; and the smoke channel communicates with the heating chamber. 
     
     
         11 . The atomizer of  claim 10 , wherein the atomizing tube comprises a distal end away from the mouthpiece; the atomizer further comprises a second sealing member disposed between the distal end of the atomizing tube and the housing; and the second sealing member is configured to seal the other end of the e-liquid chamber. 
     
     
         12 . The atomizer of  claim 10 , wherein the distal end of the atomizing tube expands radially and longitudinally extends to form both an air guide tube and a first positioning step; the housing comprises a distal end away from the mouthpiece; the distal end of the housing abuts against the first positioning step; and an outer wall of the air guide tube comprises at least one air inlet. 
     
     
         13 . The atomizer of  claim 12 , wherein:
 the atomizer further comprises a first conductive connector; the first conductive connector comprises an insert section and a protruding section connected to the insert section; the insert section is disposed inside the air guide tube; the protruding section is disposed outside the air guide tube; a joint of the insert section and the protruding section extends radially to form a second positioning step; the air guide tube comprises a distal end away from the mouthpiece; the distal end of the air guide tube abuts against the second positioning step; an air guide space is defined by the air guide tube, the insert section, and the second positioning step; and the at least one air inlet communicates with the air guide space;   an outer wall of the insert section comprises at least one air guide hole communicating with the air guide space; the first conductive connector comprises an air guide channel; the at least one air guide hole communicates with the air guide channel; the air guide channel corresponds to and communicates with the heating chamber;   the atomizer further comprises a second conductive connector disposed in the protruding section; the first conductive connector and the second conductive connector are electrically connected to the heating element; the atomizer further comprises an insulating component disposed between an inner wall of the protruding section and an outer wall of the second conductive connector; and   the atomizer further comprises e-liquid collection cotton disposed within the insert section; the e-liquid collection cotton is configured to absorb condensation escaping from the heating chamber and e-liquid escaping from the heating core.
