electronic cigarette according to an embodiment of the present
invention.
[0016] FIG. 2 is a schematic diagram of the circuit of an
electronic cigarette according to another embodiment of the present

DETAILED DESCRIPTION OF THE INVENTION
[0017] It is needed to state that embodiments and all element
limitations in all embodiments may be combined in the case of no
conflicts. The present invention will be described in detail in the
following combining figures and embodiments.
[0018] FIG. 1 and FIG. 2, the present invention provides an
electronic cigarette and circuit to resolve the problem of the
current electronic cigarette as that when the airflow sensor does
not work, it leads to malfunction of the electronic cigarette and
the electronic cigarette can not be used and causing energy
waste.
[0019] The electronic cigarette circuit includes a power supply, a
micro-controller and a heater for heating and producing smoke,
which constitute a loop by electrically connected in turn.
Furthermore, the electronic cigarette circuit includes at least two
airflow sensors electrically connected to the micro-controller and
adapted for sensing airflow in the electronic cigarette and
outputting the sensing signal. The micro-controller conducts the
loop according to the sensing signal. In the embodiment, the
micro-controller is a single-chip microcomputer (SCM).
[0020] As an embodiment, the airflow sensor is also used to obtain
the airflow direction of the electronic cigarette to determine the
type of air pressure and output the sensing signal such that the
micro-controller processes the sensing signal to detect the air
pressure entering the electronic cigarette. Then, the
micro-controller controls the electronic cigarette turn-on or
turn-off based on the detected air pressure. The control principle
is the same as the airflow sensor controls airflow by sensing,
which will not be repeated.
[0021] As an embodiment, there are at least two micro-controllers,
both of which are electrically connected with an airflow sensor
respectively. Preferably, referring to FIG. 1, there are two
micro-controllers, both of which are electrically connected with an
airflow sensor respectively. One micro-controller and one airflow
sensor are integrated on a printed circuit board to be an airflow
sensor-controller. The two airflow sensor-controllers are series
connected. The airflow sensors, or called as two airflow
sensor-controllers, shall work simultaneously to conduct the loop
effectively.
[0022] As another embodiment, there is only one micro-controller,
which is electrically connected with at least two airflow sensors.
The micro-controller conducts the loop according to the sensing
signal detected by all the airflow sensors. Preferably, referring
to FIG. 2, there are two airflow sensors, both of which work
simultaneously to make the micro-controller to conduct the loop
effectively.
[0023] The present invention also provides an electronic cigarette
which includes an inhalation pole and a power supply pole adapted
to connect with each other. Specifically, the inhalation pole and
the power supply pole are connected by screwthreads. Furthermore,
the electronic cigarette includes above-mentioned electronic
cigarette circuit disposed therein.
[0024] The inhalation pole has an atomizer disposed therein. The
atomizer has the heater disposed therein.
[0025] The power supply pole has lithium batteries or Farad
capacitor inside for power supplying.
[0026] Assuming that the failure rate of using only one airflow
sensor as X, and the failure rate of the electronic cigarette of
the present invention which adapts "n" airflow sensors electrically
connected with micro-controller is Y, then the following formula is
established: Y=X.sup.n. For example, the failure rate of an airflow
sensor is 0.1%, but the failure rate of the electronic cigarette
will be reduced to 10.sup.-6 when the electronic cigarette uses two
connected airflow sensors. Obviously, the technology solution of
the present invention can exponentially reduce the failure rate of
the electronic cigarette caused by the airflow sensors'
malfunction.
[0027] The above-mentioned is embodiments of the present invention.
It is pointed out that various improvement and modifications can be
made to the embodiments by those skilled in the art without
departing from the true spirit and scope of the disclosure as
defined by the appended claims.
