The method for controlling the output self-protection of the electronic atomizer according to the preferred embodiment of the present invention, as shown in fig. 2 and referring to fig. 3, includes the following steps:
s01: the control assembly of the atomizer is additionally provided with a self-protection control unit which is in communication connection with the logic control unit, the enabling detection unit and the output driving unit;
s02: after the enabling detection unit detects an effective trigger signal of the sensor, the enabling detection unit outputs a signal to the logic control unit, and the logic control unit prepares before driving output and triggers the self-protection control unit to work;
s03: the self-protection control unit judges whether the current running state of the electronic atomizer reaches a set self-protection condition, if so, the enabling detection unit and the output driving unit are closed, and if not, the output driving unit is opened for outputting;
s04: after the output is finished, the self-protection control unit restores the standby state and waits for the next time that the sensor inputs an effective trigger enabling signal;
according to the invention, the abnormal monitoring mechanism is added in the logic control unit, so that the chip can judge the abnormal condition, the output is stopped and the enabling detection unit is closed after the chip is output and driven for a plurality of times to overtime, the condition that the load is overheated or even spontaneously combusted due to the fact that the external load is output and driven for a long time under extreme conditions is avoided, the risk of spontaneous combustion can be further avoided, and the safety of the electronic atomizer is greatly improved; in addition, peripheral devices and interfaces of the circuit are not required to be added, and the circuit cost is low.
The technical scheme of the invention is that a self-protection control circuit is added on the basis of the traditional scheme to realize judgment, record and disposal of abnormal conditions, so that the invention also has the advantages of simple setting and low cost. In general, the effective trigger signal generated by the external sensor at each time has different time duration, but does not exceed the preset duration threshold T of the logic control unit, and if the single effective trigger duration exceeds T, the logic control unit in the conventional scheme only turns off the output drive and returns to a standby state to wait for the next sensor signal input. If the sensor continuously generates effective trigger signals for multiple times due to abnormal reasons, the circuit outputs and drives the load to overtime for multiple times and the load is overheated.
After the self-protection control circuit is added, when the sensor is detected to effectively trigger the output ready to drive the load every time, the self-protection control circuit can detect and judge whether the output is overtime or not, if the output is overtime, the output is judged to be abnormal, the abnormal times are accumulated, if the abnormal times exceed a certain number, the condition that the abnormal triggering is really carried out outside is determined, the circuit needs to start self-protection, then the circuit is closed to enable the detection and output driving unit, and the condition that the output driving load is overheated for a long time is avoided.

the mode of this application is not restricted to the electron cigarette, equally can apply to all electron atomizers and goods thereof, can also be applied to on the arbitrary other products that are provided with the electron atomizer, all belong to this application protection scope based on the transform of above-mentioned mode.
Preferably, in the third step, the implementation method is as follows:
the self-protection control unit judges whether the abnormality counter CNT is larger than a set abnormality detection threshold value N, if CNT is larger than N, the enabling detection unit and the output driving unit are closed, and if CNT is less than or equal to N, the output driving unit is opened for outputting;

the self-protection control circuit presets an abnormality detection threshold value N, after the circuit is powered on, the self-protection control circuit clears an abnormality detection counter CNT to zero, the circuit is in a standby state, and an external sensor is waited to input an effective trigger enabling signal.
After the enabling detection unit detects the effective trigger signal of the sensor, the enabling detection unit outputs a signal to the logic control unit, the logic control unit performs preparation before driving output, and the self-protection control circuit is started.
The self-protection control circuit firstly judges whether the abnormality counter CNT is larger than the abnormality detection threshold value N, if the CNT is larger than the N, the condition of multiple continuous abnormal triggers exists, the self-protection circuit closes the enabling detection unit and the output driving unit, namely, after the electricity is subjected to self-protection, the circuit can not output driving loads again until the electricity is powered off and is powered on again, and the reliability is high.
If the self-protection control circuit judges that CNT is less than or equal to N, the logic control unit normally opens the output drive. After the output is finished, the self-protection circuit judges whether the output is overtime or not, if yes, the abnormal counter CNT is accumulated by 1, and if not, the abnormal counter CNT is cleared.
The circuit returns to the standby state again and waits for the next time the sensor input is valid to trigger the enabling signal.
