fig. 1 is an electrical circuit diagram of an engine safety starter according to an embodiment, and as shown in fig. 1, the engine safety starter according to an embodiment includes a main power switch 100, a preheating switch 101, a controller 102, a fuel solenoid valve 103, and a flame glow plug 104:
the first switch end A of the total power switch 100 is used for being connected with an external power supply, the second switch end B of the total power switch 100 is connected with the power supply end of the preheating switch 101, and the third switch end C of the total power switch 100 is connected with the starting power supply input end Vin of the controller 102; the main power switch 100 is configured to switch on the first switch terminal a, the second switch terminal B, and the third switch terminal C according to user trigger;
wherein the user may trigger the main power switch 100 to turn on the first switch terminal a and the second switch terminal B, or to turn on the first switch terminal a, the second switch terminal B, and the third switch terminal C. When the first switch end A and the second switch end B are switched on, an external power supply can supply power to the second switch end B; when the first, second and third switch terminals a, B and C are turned on, the external power source may supply power to the second and third switch terminals B and C, respectively.
In one embodiment, the main power switch 100 may be an ignition switch or a multi-speed rotary switch. Fig. 2 is a panel diagram of a total power switch according to an embodiment, and as shown in fig. 2, the total power switch 100 is an ignition switch. The ignition switch includes three gear positions "0", "i" and "ii". The user can rotate the ignition switch through the engine key, and when the ignition switch rotates to a gear '0', the first switch end A, the second switch end B and the third switch end C are separated; when the ignition switch rotates to a gear position 'I', the first switch end A and the second switch end B are connected; when the ignition switch rotates to a gear position 'II', the first switch end A, the second switch end B and the third switch end C are turned on.
When the second switch end B obtains power supply of an external power supply, the preheating switch 101 end obtains power supply; when the third switch terminal C obtains the external power supply, the input terminal of the controller 102 obtains the power supply.
The signal output end of the preheating switch 101 is connected with a trigger signal input end P1 of the controller 102, the first power output end of the controller 102 is connected with the flame preheating plug 104, the second power output end of the controller 102 is connected with the fuel electromagnetic valve 103, and the third power output end of the controller 102 is used for being connected with the starting motor; the starting power supply input end Vin is normally open with the first power supply output end, the starting power supply input end Vin is normally open with the second power supply output end, and the starting power supply input end Vin is normally closed with the third power supply output end;
the preheating switch 101 is used for outputting a trigger signal at the signal output end according to user trigger when the power supply end is connected with an external power supply;
in one embodiment, the preheat switch 101 may be a toggle switch or a reset switch. Taking the preheating switch 101 as an example, a reset switch is selected, after the preheating switch 101 is triggered by a user, the signal output end of the preheating switch 101 outputs a trigger signal and resets, and after the reset, the trigger signal is not output any more.
After the trigger signal input terminal P1 receives the trigger signal, the controller 102 turns on the starting power input terminal Vin and the first power output terminal, turns off the starting power input terminal Vin and the third power output terminal, and turns on the starting power input terminal Vin and the second power output terminal, and turns on the starting power input terminal Vin and the third power output terminal.
The trigger signal input end P1 of the controller 102 does not need to continuously receive the trigger signal, and after the trigger signal input end P1 receives the trigger signal, the start power input end Vin and the first power output end are turned on, and after the start power input end Vin and the third power output end are turned off for a first preset period of time, the start power input end Vin and the second power output end are turned on, and the start power input end Vin and the third power output end are turned on.

If the trigger signal input terminal P1 of the controller 102 receives the trigger signal, the starting power input terminal Vin is disconnected from the third power output terminal, and the starting motor is not powered. At this time, the starting power input terminal Vin is connected to the first power output terminal, the flame glow plug 104 is operated after being supplied with power, and the flame glow plug 104 is heated to the operating temperature after being operated for a first preset period of time.
In one embodiment, the device further comprises an indicator light connected with the controller 102; after the signal output end of the preheating switch 101 outputs the trigger signal for a first preset period of time, the controller 102 outputs a lighting signal to enable the indicator lamp to be powered on. The user is prompted by an indicator light that the temperature increase of the flame glow plug 104 is complete.
In one embodiment, as shown in FIG. 1, the controller 102 also includes a power supply input VCC.
The power input VCC is connected to the preheat switch 101. As shown in fig. 1 and 2, when the ignition switch is rotated to the gear "i", that is, the first switch terminal a and the second switch terminal B are turned on, the power supply of the external power source such as the storage battery is output to the preheating switch 101, and the preheating switch 101 is supplied with power while outputting the power supply to the power supply input terminal VCC to supply the controller 102 with power. When the ignition switch is rotated to the gear "ii", the first switch terminal a, the second switch terminal B and the third switch terminal C are turned on, and the power input terminal VCC of the controller 102 can be supplied with power.
In one embodiment, as shown in fig. 1, the controller 102 further includes a preset time signal output end Clock, where the preset time signal output end Clock is connected to the preheating switch 101, and the preset time signal output end Clock is configured to output a preset time signal through the preheating switch 101, so that the indicator lamp is powered on.
After receiving the trigger signal for a first preset period of time, the trigger signal input end P1 of the controller 102 is connected to the starting power input end Vin and the second power output end, the fuel solenoid valve 103 is powered and then is opened to supply oil, at this time, a pressure of not less than 0.15Mpa is formed between the flame glow plug 104 and the engine evaporation tube, and the fuel flame with fire is injected to each piston cylinder, so that the cold starting performance of the engine is greatly improved. Meanwhile, the input end Vin of the starting power supply is communicated with the output end of the second power supply, and the starting motor is powered to start until the set rotating speed is reached.
In one embodiment, the controller 102 may be an electronic switch or a switch chip, etc. The first preset time period may be set by setting a switching threshold of the electronic switch or the switching chip.

Fig. 3 is a view showing the engine start aging, as shown in fig. 3, in 20s after the first preset time period, as the starter motor ignites, each element is in operation when in the "ON" state, and the engine minimum flywheel speed rises to the set speed rpm in a relatively gentle manner.
The engine safety starter of any of the above embodiments may enable the power supply terminal of the preheating switch 101 and the starting power input terminal Vin of the controller 102 to be powered on by triggering the first switch terminal a, the second switch terminal B and the third switch terminal C of the main power switch 100. When the engine works at normal temperature, the input end Vin of the starting power supply is communicated with the output end of the third power supply, so that the starting motor is started normally. When the engine is in a low-temperature state, a user can trigger the preheating switch 101 to enable the signal output end to output a trigger signal, and after the starting power input end Vin and the first power output end are connected and the starting power input end Vin and the third power output end are disconnected for a first preset period of time, the starting power input end Vin and the second power output end are connected, and the starting power input end Vin and the third power output end are connected. Based on this, when the engine is operated in a low temperature state, the flame glow plug 104 is preheated for a first preset period of time, and then the fuel solenoid valve 103 and the starter motor are operated, so that the fuel is effectively prevented from being retained in the air inlet pipeline, and the normal operation of the engine is ensured. At the same time, by the sequential operation of the elements, the user is prevented from overusing the flame glow plug 103.
