Atomizer and electronic cigarette having the same

Abstract

The present disclosure relates to an atomizer and an electronic cigarette. The atomizer includes a liquid reservoir, an atomizing core and a mouthpiece. The liquid reservoir is provided with an liquid storage cavity and an accommodating channel, and the accommodating channel is in communication with the liquid storage cavity; the atomizing core is movably disposed in the accommodating channel, and the atomizing core is in communication with the liquid storage cavity; the mouthpiece is movably disposed in the accommodating channel, the mouthpiece is movably abutted against the atomizing core, and the mouthpiece is configured to push the atomizing core out of the accommodating channel and movably block the liquid storage cavity.

What is claimed is: 
     
         1 . An atomizer, comprising:
 a liquid reservoir provided with a liquid storage cavity and an accommodating channel therein, and the accommodating channel being in communication with the liquid storage cavity;   an atomizing core movably disposed in the accommodating channel, and the atomizing core being in communication with the liquid storage cavity;   a mouthpiece movably disposed in the accommodating channel, the mouthpiece movably abutting against the atomizing core, wherein the mouthpiece is configured to push the atomizing core out of the accommodating channel and block the liquid storage cavity.   
     
     
         2 . The atomizer according to  claim 1 , wherein the mouthpiece is provided with a smoke channel, and one end of the atomizing core extends at least partially into the smoke channel. 
     
     
         3 . The atomizer according to  claim 2 , wherein the atomizing core is provided with a step portion at a sidewall thereof abutting against the mouthpiece. 
     
     
         4 . The atomizer according to  claim 1 , further comprising a sleeve detachably disposed in the accommodating channel and sleeved on the atomizing core, wherein the sleeve is in communication with the liquid storage cavity. 
     
     
         5 . The atomizer according to  claim 4 , wherein an inner diameter of the sleeve is 8 mm, 9 mm, 10 mm, 11 mm or 12 mm. 
     
     
         6 . The atomizer according to  claim 4 , wherein a sidewall of the sleeve is configured to separate the liquid storage cavity and the accommodating channel. 
     
     
         7 . The atomizer according to  claim 6 , wherein the sleeve is provided with a first anti-leak groove on a sidewall thereof. 
     
     
         8 . The atomizer according to  claim 1 , wherein the mouthpiece is provided with a second anti-leak groove on an outer sidewall thereof. 
     
     
         9 . The atomizer according to  claim 1 , wherein the liquid reservoir is provided with a liquid injection hole in communication with the liquid storage cavity. 
     
     
         10 . An electronic cigarette, comprising the atomizer according  claim 1 .
