Atomizer and electronic cigarette with same

Abstract

An atomizer can include an atomizing pipe, a liquid storage chamber and a liquid retainer. The atomizing pipe can include an injection port in a sidewall thereof. The liquid storage chamber is defined in the atomizing pipe. The liquid retainer is movably coupled to the atomizing pipe. The liquid retainer is movable relative to the atomizing pipe to adjust states of the injection port relative to an external environment, the liquid retainer is transitionable between: (i) a first configuration in which the liquid retainer covers the injection port, the injection port is not in communication with the external environment, and (ii) a second configuration in which the liquid retainer exposes the injection port to the external environment, the injection port is in communication with the external environment. An electronic cigarette with the atomizer is also provided.

What is claimed is:

         2 . The atomizer of  claim 1 , wherein the liquid retainer comprises an injection window capable of being in communication with the injection port; when the liquid retainer is in the first configuration, the injection window is not in communication with the injection port, and when the liquid retainer is in the second configuration, the injection window is in communication with the injection port. 
     
     
         3 . The atomizer of  claim 2 , wherein when the liquid retainer is in the second configuration, the injection port is exposed to the external environment via the injection window. 
     
     
         4 . The atomizer of  claim 3 , wherein the liquid retainer is a liquid retaining ring sleeved on the atomizing pipe. 
     
     
         5 . The atomizer of  claim 4 , wherein the liquid retainer has one end coupled to an elastic element which is coupled to the atomizing pipe, and when the liquid retainer moves relative to the elastic element along an axis direction of the atomizing pipe, the cigarette liquid is injectable once the injection port of the atomizing pipe is in communication with the external environment. 
     
     
         6 . The atomizer of  claim 1 , wherein the liquid retainer is a liquid retaining block coupled on the atomizing pipe. 
     
     
         7 . The atomizer of  claim 6 , wherein the atomizing pipe defines a guiding groove at a side of the injection port, the liquid retainer being slidably received in the guiding groove. 
     
     
         8 . The atomizer of  claim 6 , wherein the liquid retainer has one end rotatably coupled to the atomizing pipe by a pivot, and the other end detachably locked on the atomizing pipe. 
     
     
         9 . The atomizer of  claim 1 , further comprising two sealing elements located between the liquid retainer and the atomizing pipe, wherein the injection port is located between the two sealing elements. 
     
     
         10 . The atomizer of  claim 9 , wherein the two sealing elements seal the atomizer to prevent cigarette liquid in the liquid storage chamber from spilling from the liquid storage chamber. 
     
     
         11 . The atomizer of  claim 10 , wherein the atomizing pipe defines two sealing grooves at two opposite sides of the injection port, the two sealing elements being received in the two sealing grooves respectively. 
     
     
         12 . The atomizer of  claim 1 , further comprising a stopper configured to detachably clamp the liquid retainer to the atomizing pipe. 
     
     
         13 . The atomizer of  claim 12 , wherein the stopper is coupled to an inner wall of the liquid retainer, an external face of the sidewall of the atomizing pipe defining a limiting groove configured to couple with the stopper. 
     
     
         14 . An electronic cigarette, comprising:
 a cigarette holder and an atomizer coupled to the cigarette holder; the atomizer comprising:   an atomizing pipe comprising an injection port in a sidewall thereof;   a liquid storage chamber defined in the atomizing pipe; and   a liquid retainer movably coupled to the atomizing pipe;   wherein the liquid retainer is movable relative to the atomizing pipe to adjust states of the injection port relative to an external environment, the liquid retainer is changeable between: (i) a first configuration in which the liquid retainer covers the injection port, such that the injection port is not in communication with the external environment, and (ii) a second configuration in which the liquid retainer exposes the injection port to the external environment, such that the injection port is in communication with the external environment.   
     
     
         15 . The electronic cigarette of  claim 14 , wherein the liquid retainer comprises an injection window capable of being in communication with the injection port; when the liquid retainer is in the first configuration, the injection window is not in communication with the injection port, and when the liquid retainer is in the second configuration, the injection window is in communication with the injection port. 
     
     
         16 . The electronic cigarette of  claim 15 , wherein the liquid retainer is a liquid retaining ring sleeved on the atomizing pipe. 
     
     
         17 . The electronic cigarette of  claim 16 , wherein the liquid retainer has one end coupled to an elastic element which is coupled to the atomizing pipe, and when the liquid retainer moves relative to the elastic element along an axis direction of the atomizing pipe, the cigarette liquid is injectable once the injection port of the atomizing pipe is in communication with the external environment.
