         [0047]    The atomization cup  52  includes a liquid-storage member  521 , a support tube  522  and an atomization seat  523 . Both the liquid-storage member  521  and the support tube  522  are substantially cylindrical and coaxially arranged. 
         [0048]    The liquid-storage member  521  is a hollow cylindrical structure, and is capable of absorbing and storing liquid like a sponge for absorbing and storing e-liquid to facilitate the atomizer  51  to vaporize the e-liquid subsequently. In the embodiment, the liquid-storage member  521  may be made of fiberglass, absorbent cotton and other materials capable of absorbing and storing liquid. The liquid-storage member  521  is sheathed in the main rod body  10  and tensioningly assembled with the inner wall of the main rod body  10 . 
         [0049]    The support tube  522  also is a hollow cylindrical structure, and is made of fiberglass material.

The atomization control switch  61  is fixed in the main rod body  10  by a switch fixing seat  62 . 
         [0052]    In the embodiment, the atomization control switch  61  is a sensor switch, specifically, the sensor switch is a capacitive sensor switch. When users using the electronic cigarette  100  for smoking, the capacitive sensor switch sensors the capacitance change after inhalation of airflow and then controls the atomization control circuit to switch on the power supply, making the electronic cigarette  100  be in working state. As an alternative embodiment, the sensor switch may also be disposed as an airflow sensor switch, that is when users inhaling by the suction nozzle  20 , the chamber of the electronic cigarette  100  generates negative pressure to make the airflow sensor switch generating pulse signals to control the atomization control circuit to switch on the power supply. 
         [0053]    Because manufacturing of the sensor switch is of precision, and the sensor switch generally disposes a special controller therein, the atomization control circuit of the present embodiment may be directly integrated on the controller in the sensor switch. As an alternative embodiment, the atomization control circuit also may be integrated on an atomization control circuit board which is independently disposed at the outer of the sensor switch and connected with the sensor switch and the battery  30  respectively. As an alternative embodiment, the atomization control switch  61  also may be disposed as a traditional key switch.

The light-emitting device is used as a work indicating light of the electronic cigarette  100 , and includes a light-emitting unit electrically connected with the battery  30  and a light cap  70  which is sheathed on the outer of the light-emitting unit. 
         [0055]    Referring to  FIG. 1  and  FIG. 2 ,  FIG. 1  and  FIG. 2  shows a first embodiment of the present invention. In the embodiment, the one-way valve  40  is disposed between the suction nozzle  20  and the atomization device  50 . At the connection between the light cap  70  and the main rod body  10  disposes an air inlet  80  communicating with the gas guide hole  44  to form the inhalation air path in the main rod body  10  throughout the main rod body  10 . Referring to  FIG. 2 , the direction indicated by arrow shown  FIG. 2  is airflow direction of the inhalation air path of the embodiment. 
         [0056]    Specifically, the valve seat  42  is sheathed at the outer of the valve core  41  and tensioningly fixed in the main rod body  10  by using the outer wall. Meanwhile, the valve core  41  is abutted between the valve seat  42  and the atomization device  50 . The middle of the valve core  41  extends along axial direction to form a support column extending into the support tube  522 . The gas guide hole  44  communicates with the first gas guide hole  5231  of the atomization seat  523  by the support tube  522 . The atomization seat  523  abuts with the battery  30  by a bracket  13 . One end of the bracket  13  near the battery  30  disposes a second gas guide hole  131  axially throughout the sidewall of the bracket  13 . 
         [0057]    When users using the electronic cigarette  100  of the present embodiment smoking, users align with the inhalation hole  22  of the suction nozzle  20  to inhale, external air enters into the main rod body  10  through the air inlet  80  at the connection between the light cap  70  and the main rod body  10 . Air enters into the atomization device  50  along the sidewall of the battery rod  12  through the second gas guide hole  131  on the sidewall of the bracket  13 ., when air flows through the support tube  522  of the atomization device  50 , airflow drives the aerosol vaporized by the atomizer  51  to flow toward the suction nozzle  20 . When air flows through the gas guide hole  44 , the valve flap  43  generates elastic deformation under airflow pressure and separates from the gas guide hole  44 , then the gas guide hole  44  is through, the aerosol flows out from the inhalation hole  22  through the gas guide hole  44  along with the airflow and finally inhaled by human body. When blowing, airflow flows reversely, the valve flap  43  is firmly attached with the end surface of the corresponding vent port of the gas guide hole  44  under the airflow pressure by blowing, then the gas guide hole  44  is sealed, the blowing airflow is blocked and unable to enter into the atomization device  50 . The aerosol and the e-liquid in the atomization device  50  never flows to the battery  30  and the atomization control switch  61  without airflow driven, therefore avoid the damage of the battery  30  and the atomization control switch  61  caused by the aerosol and the e-liquid, ensuring the working life of the electronic cigarette  100 . 
         [0058]    Referring to  FIG. 3  and  FIG. 4 ,  FIG. 3  and  FIG. 4  shows a second embodiment of the present invention. In the embodiment, the one-way valve  40  is disposed between the battery  30  and the atomization device  50 . Also, at the connection between the light cap  70  and the main rod body  10  disposes the air inlet  80  communicating with the gas guide hole  44  to form an inhalation air path throughout the main rod body  10 . Referring to  FIG. 4 , the direction indicated by arrow shown  FIG. 4  is airflow direction of the inhalation air path of the embodiment. 
         [0059]    Specifically, in the embodiment, the valve seat  42  is sheathed at the external of the valve core  41  and tensioningly fixed in the main rod body  10  by using the outer wall thereof. The valve core  41  is firmly abutted between the valve seat  42  and the atomization device  50  by the valve seat  42 . The valve seat  42  and the valve core  41  correspondingly disposes a second threading hole  45  for the two ends of the heating wire  511  passing through, and one end of the valve seat  42  near the battery  30  axially disposes a third gas guide hole  46  communicating with the gas guide hole  44 . 
         [0060]    When users using the electronic cigarette  100  of the present embodiment smoking, users align the inhalation hole  22  to inhale, external air enters into the main rod body  10  through the air inlet  80  at the connection between the light cap  70  and the main rod body  10 . Air enters into the gas guide hole  44  along the sidewall of the battery rod  12  through the third gas guide hole  46  on the sidewall of the valve seat  42 , the valve flap  43  generates elastic deformation under airflow pressure and separates from the gas guide hole  44 , then the gas guide hole  44  is through, the airflow enters in to the support tube  522  through the first gas guide hole  5231  which is axially through on the atomization seat  523 . When flowing through the atomizer  51 , airflow drives the aerosol vaporized by the atomizer  51  to flow out from the inhalation hole  22  and finally inhaled by human body. When blowing, the airflow flows reversely and when reaching the one-way valve  40 , the valve flap  43  is firmly attached with the end surface of the corresponding vent port of the gas guide hole  44  under the airflow pressure, then seals the air path of the blowing airflow. At this time, because the blowing airflow is blocked by the one-way valve  40 , aerosol and e-liquid in the atomization device  50  is blocked at one side of the one-way valve  40  near the atomization device  50 , then avoid aerosol and e-liquid entering into the battery rod  12  to affect the working life of the battery  30  and the atomization control switch  61  in the battery rod  12 . 
         [0061]    Referring to  FIG. 5 ,  FIG. 5  shows a third embodiment of the present invention. In the embodiment, the one-way valve  40  is disposed at the same position as the aforementioned second embodiment, and is also located between the battery  30  and the atomization device  50 . The difference is that the air inlet  80  is disposed on the sidewall of one end of the main rod body  10  corresponding to the battery  30  near the inhalation rod  11 , therefore blowing airflow directly enters into the inhalation rod  11  without passing the battery rod  12 . When the air inlet  80  is disposed on the sidewall of the main rod body  10 , the third gas guide hole  46  on the valve seat  42  may be only disposed on the sidewall of the end corresponding to the air inlet  80 . Certainly, the air inlet  80  specified in the present embodiment also may be disposed at any proper position on the sidewall of the main rod body  10 ; or may be disposed at the connection between the main rod body  10  and the light cap  70  simultaneously, as long as it is assured that the inhalation airflow is capable of entering into the atomization device  50  to drive the vaporized aerosol flowing out from the suction nozzle  20  for human body inhalation. 
         [0062]    When users using the electronic cigarette  100  of the present embodiment smoking, users align the inhalation hole  22  to inhale, external air enters into the gas guide hole  44  through the air inlet  80  disposed on the sidewall of the main rod body  10  and the third gas guide hole  46  disposed on the sidewall of the valve seat  42 , the valve flap  43  generates elastic deformation under airflow pressure and separates from the gas guide hole  44 , then the gas guide hole  44  is through, the airflow enters in to the support tube  522  through the gas guide hole  44  and the first gas guide hole  5231  of the atomization seat  523 , and drives the aerosol vaporized by the atomizer  51  to flow out from the inhalation hole  22  when flowing through the atomizer  51 , then make human body inhale the vaporized aerosol. Similarly to the second embodiment, the valve flap  43  seals the gas guide hole  44  under the blowing airflow pressure, then avoid the aerosol and the e-liquid entering into the battery rod  12  along with the blowing airflow, therefore effectively guarantees the working life of the battery  30  and the atomization control switch  61 . 
         [0063]    It is understood that the electronic cigarette  100  described in the embodiment of the present invention is not only limited to the three embodiments shown in  FIG. 1  and  FIG. 5 . The technology characteristics of these embodiments can be combined with each other to form new embodiments. 
         [0064]    Referring to  FIG. 12 , the electronic cigarette  100  is generally placed in the electronic cigarette box  200 . The electronic cigarette box  200  includes a bottom box  91  operable to accommodate the electronic cigarette  100  and a box cover  92  covering the bottom box  91 . The bottom box  91  is a square shell structure, and certainly, the shape is not limited to square, and also may be circular, oval, polygonal and etc as long as it is ensured that the box cover  92  matches with the bottom box  91  when arranging the box cover  92 .
