Specifically, the thermistor is correspondingly arranged at a position close to the flashlight, and the temperature of the flashlight can be conducted to the thermistor, so that the temperature of the flashlight can be obtained by detecting the temperature of the thermistor.
Specifically, as shown in fig. 3 and 4, fig. 3 is a schematic structural diagram of a temperature obtaining module in an embodiment of the present application, and fig. 4 is a schematic flow chart of obtaining the temperature of the flash lamp by the temperature obtaining module in fig. 3. The temperature acquisition module 20 may generally include a thermistor NTC, a voltage dividing resistor R1, and an analog-to-digital converter ADC. The first end of the divider resistor R1 is externally connected with a power supply Vcc, the second end of the divider resistor R1 is connected with the first end of the thermistor NTC, and the second end of the thermistor NTC is grounded.

Specifically, first, the voltage value V across the thermistor NTC may be detected by the analog/digital converter ADC NTC . The voltage value is then substituted into the following equation:
wherein R is (t) Represents the resistance value R of the NTC of the thermistor at the temperature t 1 Represents the resistance value, V, of the voltage dividing resistor R1 NTC Indicating the value of the voltage, V, of the NTC of the thermistor detected by the A/D converter ADC CC Denotes the voltage value of the power supply, T denotes the normal temperature of 25 DEG, TRepresents the actual temperature of the thermistor NTC, B is a material constant, and R represents the resistance value of the thermistor NTC at the normal temperature T.
In some embodiments, the temperature acquiring module 20 may acquire the temperature of the flash lamp in real time, so as to make the control more precise. In other embodiments, the temperature acquisition module 20 may also acquire the temperature of the flash lamp every other time period to save energy consumption. The temperature acquisition interval of the temperature acquisition module 20 is not specifically limited in the embodiment of the present application.
Further, referring to fig. 2, after the temperature obtaining module 20 obtains the temperature of the flash, the step S103 is executed to continue: and when the temperature of the flash lamp exceeds a preset temperature threshold value, sending safety prompt information.
Specifically, the execution module 30 sends out the safety prompt message when the temperature of the flash lamp exceeds a preset temperature threshold.

Specifically, referring to fig. 5, fig. 5 is a schematic flowchart of step S103 in fig. 2. In this embodiment, when the temperature of the flash lamp exceeds the preset temperature threshold, the step of sending the safety prompt message specifically includes:
step S301: a preset temperature threshold of the flash lamp is determined.
The execution module 30 first determines the magnitude of a preset temperature threshold of the flash. Specifically, a plurality of temperature thresholds with different sizes are preset in the execution module 30, and the execution module 30 selects one of the temperature thresholds as a preset temperature threshold corresponding to different control strategies. For example, the number of the preset temperature thresholds may include one, two, or more, and the embodiments of the present application are not particularly limited, and may be flexibly set as needed.

step S401: whether the flash lamp is shielded or not is detected.
Specifically, as shown in fig. 1, the electronic device 100 further includes a distance sensor 40, and the distance sensor 40 is used for detecting whether the flash is shielded. The distance sensor 40 may be, for example, an infrared distance sensor, a radar, an ultrasonic distance sensor, or the like, and the embodiment of the present application is not particularly limited.
The distance sensor 40 detects whether a barrier exists within a preset distance from the flash to determine whether the flash is blocked. That is, when the distance sensor 40 detects that there is a shield within a preset distance from the flash, it is determined that the flash is shielded. When the distance sensor 40 detects that there is no obstruction within a preset distance from the flash, it is determined that the flash is not obstructed.
In one embodiment, the preset distance may be set to 3 cm. That is, when the distance sensor 40 detects that the distance between the shade and the flash lamp is within 0-3cm (including 3cm), it indicates that the flash lamp is shaded. When the distance sensor 40 detects that the distance between the barrier and the flash is greater than 3cm, it indicates that the flash is not blocked.
It is understood that in other embodiments, the preset distance may be flexibly set according to the requirement. For example, the preset distance may be set to 2cm, 2.2cm, 2.4cm, 2.6cm, 2.8cm, 2.9cm, 3.2cm, 3.4cm, 3.6cm, 3.8cm, or 4cm, etc., and the embodiment of the present application is not particularly limited.
If it is detected that the flash is blocked, step S402 is executed: the preset temperature threshold is set to a first preset temperature.
Specifically, if the distance sensor 40 detects that the flash is blocked, that is, the distance sensor 40 detects that a blocking object exists within a range of 3cm around the distance sensor 40, the execution module 30 uses the first preset temperature as the determined preset temperature threshold.
After the preset temperature threshold of the flash lamp is obtained through the above steps, the step S302 is continuously executed: and if the difference value between the acquired temperature of the flash lamp and the preset temperature threshold is greater than or equal to zero, sending safety prompt information.
Specifically, the temperature obtaining module 20 feeds back the obtained temperature of the flash lamp to the execution module 30, the execution module 30 compares the temperature fed back by the temperature obtaining module 20 with the preset temperature threshold determined in step S402, and obtains a difference between the temperature of the flash lamp and the preset temperature threshold, if the difference between the temperature of the flash lamp and the preset temperature threshold is greater than or equal to zero, it indicates that the temperature of the flash lamp exceeds the preset temperature threshold, and at this time, the execution module 30 sends out a safety prompt message to remind the user.
This embodiment is through being regarded as first preset temperature with less temperature value in the temperature threshold value that sets up in advance, can be so that under the condition that the flash light was sheltered from, when the temperature of flash light reached a less temperature, send safety prompt promptly to the temperature is higher when avoiding the flash light to be sheltered from, takes place condition such as scald or conflagration.
In some embodiments, the first preset temperature may be set to 48 ℃, for example, that is, when the distance sensor 40 detects that the flashlight is blocked by the blocking object and the temperature acquisition module 20 detects that the temperature of the flashlight exceeds 48 ℃, a safety prompt message is issued to remind the user. Of course, in other embodiments, the first preset temperature may also be set to 35 ℃, 38 ℃, 40 ℃, 43 ℃, 45 ℃, 47 ℃, 49 ℃, 51 ℃, 53 ℃, 55 ℃, 58 ℃ or 60 ℃ or the like, and the embodiments of the present application are not particularly limited.
Referring to fig. 6, if it is detected that the flash is not blocked, step S403 is executed: the preset temperature threshold is set to a second preset temperature.
Specifically, if the distance sensor 40 detects that the flash is not shielded, that is, the distance sensor 40 detects that no shielding object exists within a range of 3cm around the distance sensor 40, the execution module 30 uses the second preset temperature as the determined preset temperature threshold.
After the preset temperature threshold of the flash lamp is obtained through the above steps, the step S302 is continuously executed: and if the difference value between the acquired temperature of the flash lamp and the preset temperature threshold is greater than or equal to zero, sending safety prompt information.
Specifically, the temperature obtaining module 20 feeds back the obtained temperature of the flash lamp to the execution module 30, the execution module 30 compares the temperature fed back by the temperature obtaining module 20 with the preset temperature threshold determined in step S403, and obtains a difference between the temperature of the flash lamp and the preset temperature threshold, if the difference between the temperature of the flash lamp and the preset temperature threshold is greater than or equal to zero, it indicates that the temperature of the flash lamp exceeds the preset temperature threshold, and at this time, the execution module 30 sends out a safety prompt message to remind the user.
The temperature that this embodiment is greater than first preset temperature through the numerical value in the temperature threshold that will set up in advance is confirmed as preset temperature threshold, can be so that under the condition that the flash light is not sheltered from, when the temperature of flash light reaches a great temperature value, just send safe suggestion to avoid the flash light not yet accomplished by the use, closed promptly, influence user experience.
In an embodiment, the second preset temperature may be set to 60 ℃, for example, that is, when the distance sensor 40 detects that the flash lamp is not shielded by the shielding object and the temperature acquisition module 20 detects that the temperature of the flash lamp exceeds 60 ℃, a safety prompt message is sent to remind the user. Of course, in other embodiments, the second preset temperature may also be set to 45 ℃, 48 ℃, 50 ℃, 53 ℃, 55 ℃, 57 ℃, 59 ℃, 61 ℃, 63 ℃, 65 ℃, 68 ℃ or 70 ℃ or the like, and the embodiments of the present application are not particularly limited.

Specifically, when the temperature acquisition module 20 detects that the temperature of the flash lamp exceeds the third preset temperature, the distance sensor 40 detects whether the flash lamp is shielded. The third preset temperature may be greater than the first preset temperature and less than or equal to the second preset temperature.
In an embodiment, the third preset temperature may be set to 60 ℃, for example, that is, when the temperature obtaining module 20 detects that the temperature of the flash lamp exceeds 60 ℃, and the distance sensor 40 detects that the barrier moves from the far direction to the near direction of the flash lamp, a safety prompt message is sent to remind the user. Of course, in other embodiments, the third preset temperature may also be set to 45 ℃, 48 ℃, 50 ℃, 53 ℃, 55 ℃, 57 ℃, 59 ℃, 61 ℃, 63 ℃, 65 ℃, 68 ℃ or 70 ℃ or the like, and the embodiment of the present application is not particularly limited.
