Thus, the laser resistance-sensing current difference is smaller than the preset resistance-sensing current difference, which indicates that the laser working current of the laser emitting chip of the electronic atomization device is too small, namely that the laser output power of the laser emitting chip of the electronic atomization device is too low, namely that the laser heating temperature of the laser emitting chip of the electronic atomization device is too low, and particularly that the temperature of the medium to be atomized in the atomizing cup of the electronic atomization device is heated by the laser emitting chip to be too low. At the moment, a laser heating current increasing signal is sent to the laser constant current output system, so that the power supply current of a constant current source connected with a laser emitting chip of the electronic atomization device is continuously increased, and the laser working current of the laser emitting chip of the electronic atomization device is increased to be within a safe current range.
In another embodiment, when the laser resistance current difference is greater than or equal to the preset resistance current difference, a laser heating current limiting signal is sent to the laser constant current output system so as to limit the laser working current of the laser emitting chip of the electronic atomization device within a safe current range, thereby avoiding the condition that the atomization temperature of the medium to be atomized in the atomizing cup of the electronic atomization device is too high.
In the actual heating process of the atomizing cup of the electronic atomizing device, the heating of the atomizing cup of the electronic atomizing device is realized through the laser irradiation emitted by the laser heater, the laser heater emits laser to the atomizing cup through an internal laser emitting chip, and particularly, the laser emitted by the laser chip in the electronic atomizing device irradiates on the atomizing cup, so that the atomizing cup is convenient for atomizing and heating the medium to be atomized stored in the atomizing cup.
However, the laser emission chip of the laser heater heats the medium to be atomized in a non-contact manner, so that the light-emitting energy of the laser emission chip is large, and the heat aggregation around the light-emitting end of the laser emission chip is increased, so that the laser emission chip is easy to burn out.
In order to improve the stability and safety of laser heating of the atomizing cup, the method comprises the following steps of:
acquiring the heat of the end point of a laser chip of the electronic atomization device;
detecting whether the endpoint heat of the laser chip is larger than or equal to the preset endpoint heat;
and when the endpoint heat of the laser chip is greater than or equal to the preset endpoint heat, feeding back a thermal recovery alarm signal to the laser constant current output system.
In this embodiment, the heat of the end point of the laser chip is the light-emitting heat of the laser emitting chip in the electronic atomization device, that is, the heat of the end point of the laser chip is the heat of the emitting end of the laser emitting chip in the electronic atomization device, that is, the heat of the end point of the laser chip corresponds to the thermodynamic system balance of the emitting end of the laser emitting chip in the electronic atomization device. The endpoint heat of the laser chip is larger than or equal to the preset endpoint heat, which indicates that the heat of the emitting end of the laser emitting chip in the electronic atomization device is overlarge, namely that the thermodynamic balance of the emitting end of the laser emitting chip in the electronic atomization device is broken, namely that the surface of the laser emitting chip in the electronic atomization device is unbalanced, and at the moment, the laser emitting chip in the electronic atomization device has the condition of heat instant rising.
In another embodiment, when the laser chip endpoint heat is less than a preset endpoint heat, step S300 is performed.
Further, when the end point heat of the laser chip is greater than or equal to the preset end point heat, feeding back a thermal recovery alarm signal to the electronic atomization device, and then further comprising:
acquiring the alarm duration time of the electronic atomization device;
detecting whether the alarm duration is less than a preset duration;
and when the alarm duration is smaller than the preset duration, feeding back a double-pass alternating signal to the laser constant current output system.
In this embodiment, the alarm duration is an alarm time when the laser emission chip generates abnormal heat at the emission end, that is, the alarm duration is a time before the laser emission chip is turned off, that is, the alarm duration is a time when the laser emission chip continuously generates abnormal heat at the emission end. The alarm duration is smaller than the preset duration, the duration of abnormal heat of the emitting end of the laser emitting chip is indicated to be within the allowable abnormal time, namely, the emitting end of the laser emitting chip is indicated to be in an abnormal state before closing, namely, the laser emitting chip is also indicated to be in a process of waiting for closing signals, at the moment, in order to reduce the abnormal heat of the laser emitting chip to be further deteriorated, a double-pass alternating signal is fed back to the laser constant current output system, so that the auxiliary laser emitting chip in the electronic atomizing device is started, the electronic atomizing device is enabled to work by adopting double chips, and at the moment, the two adopted chips work in an alternating emitting mode, specifically, the duty ratio of PWM driving signals of the two laser chips is adjusted to be 50%, so that the double-channel laser heating is realized, the damage probability of the laser emitting chip before closing the electronic atomizing device is effectively reduced, and the heating speed and the efficiency of the laser heating temperature of the atomizing cup can be improved.
Still further, the detecting whether the alarm duration is less than a preset duration further includes:
and when the alarm duration is greater than or equal to the preset duration, feeding back a single-channel emission signal to the laser constant current output system.
In this embodiment, the alarm duration is greater than or equal to the preset duration, which indicates that the duration of occurrence of abnormal heat of the transmitting end of the laser transmitting chip is outside the allowable abnormal time, that is, indicates that the transmitting end of the laser transmitting chip is still in an abnormal state that is not closed, that is, indicates that the laser transmitting chip is still waiting for a closing signal and exceeds the allowable closing time. In order to avoid the situation that the laser emission chip cannot be closed, the laser irradiation is continuously performed according to the previous mode, so that the laser emission chip outputs laser in a single channel by feeding back a single-channel emission signal to the laser constant-current output system, specifically, the laser emission chip is in a single-frequency laser emission mode, the laser emitted by the laser emission chip is in a single frequency, the duty ratio of a PWM driving signal of the laser emission chip is maintained at 10-15%, and the laser emission chip is in a working mode under standby power consumption, namely, the emission power at the initial start-up time, so that the probability of damaging the laser emission chip is further reduced.
The above-mentioned various preset variables all set up in the database, are convenient for in time draw, and different preset variables are put in different memory cell, namely in different memory stacks, and laser chip endpoint heat and warning duration accessible corresponding detector gathers, for example, gather through the calorimeter and the time-recorder in the laser resistance sense collection module.
