Electronic cigarette for convenient battery charging and atomizer starting

1. An electronic cigarette, comprising:

an atomizer; and

a battery component connecting with the atomizer at one end thereof, the battery component comprising:

a battery sleeve;

a rechargeable battery received in the battery sleeve; and

a battery seat disposed at the other end of the battery component opposite to the one end thereof to connect with the atomizer, an opening formed at a distal end of the battery seat facing away from the atomizer to allow electrical connection between a power supply and the rechargeable battery extending through the opening;

wherein a positive electrode is formed at a central portion of the charging seat, a negative electrode is formed at side walls of the charging seat and surrounds the positive electrode, the opening is located between the positive electrode and the negative electrode to electrically insulate the positive electrode from the negative electrode;

wherein a first connecting component is disposed at an end of the battery component to engage and electrically connect with the rechargeable battery, and comprises at least one leaf spring formed at an inner wall of the first connecting component, a second connecting component is disposed at an end of the atomizer and comprises a circular groove formed at a distal end of the second connecting component, the second connecting component is inserted into and engaged with the first connecting component via engagement between the at least one leaf spring and the groove.

2. The electronic cigarette according to claim 1 , wherein a pneumatic switch in response to air flowing is disposed in the battery component to control electrical connection between the rechargeable battery and the atomizer.

3. The electronic cigarette according to claim 1 , wherein the opening is ring-shaped to surround entirely the positive electrode.

4. The electronic cigarette according to claim 1 , wherein the opening is spatially communicable with an air path formed between the rechargeable battery and the battery sleeve.

5. An electronic cigarette, comprising:

an atomizer; and

a battery component connecting with the atomizer at one end thereof, the battery component comprising:

a battery sleeve;

a rechargeable battery received in the battery sleeve; and

a pneumatic switch disposed in the battery component to electrically connect between the rechargeable battery and the atomizer, the pneumatic switch being responsive to air flowing in the battery component so as to control electrical connection between the rechargeable battery and the atomizer and start the atomizer based on the air flowing;

wherein a sensor is formed and extends from the pneumatic switch and the sensor is located in an annular space formed between the rechargeable battery and the battery sleeve for sensing air flowing therein.

6. The electronic cigarette according to claim 5 , wherein two connecting contacts are formed and extend from the pneumatic switch to electrically connect with the rechargeable battery and the atomizer.

7. The electronic cigarette according to claim 5 , wherein a first connecting component is disposed at an end of the battery component to engage and electrically connect with the rechargeable battery, and comprises at least one leaf spring formed at an inner wall of the first connecting component, a second connecting component is disposed at an end of the atomizer and comprises a circular groove formed at a distal end of the second connecting component, the second connecting component is inserted into and engaged with the first connecting component via engagement between the at least one leaf spring and the groove.
