Electronic lighter principle
The number of blades of the triggering impeller is equal to the number of cylinders. The upper part of the triggering impeller is set to rotate with the triggering impeller. The Hall sensor 4 is composed of a permanent magnet 3 with a guide plate (magnetic permeability) and a Hall integrated block 2. The blade of the impeller 1 is triggered to rotate between the Hall integrated block 2 and the permanent magnet 3. The Hall integrated block 2 includes a Hall element and an integrated circuit. Because the Hall signal generator works, the Hall voltage Uh generated by the Hall element is mV, the signal is very weak, and signal processing is required. This task is completed by an integrated circuit. In this way, the Hall voltage Uh signal generated by the Hall element must be amplified, pulse shaped, and finally output as a neat rectangular pulse (square wave) signal Ug.
