Description
Technical field
The invention belongs to electronic technology and power-saving technique field, be the electric cautery electrical source socket about a kind of microwave induced human body.
Background technology
The common electric cautery mode of operation sold on market never has any change, during repairing various electrical equipment, electronic equipment, typically require with instrument measurement circuit, analyze fault, collating elements, no matter whether electric cautery has people using during this period, as long as not closing the power supply of electric cautery, electric cautery is just in heated condition all the time. Suddenly going out to handle affairs or have guest visiting and forget to close electric cautery power supply if running into, electric cautery will electrified regulation for a long time, then light then burn out electric cautery, heavy then breaking out of fire potential safety hazard, but also wastes some unnecessary electric power. It addition, the Trimeresurus mucrosquamatus (Cantor). oxidation of electric cautery is burnt to death, burning out of iron core is also due to that electric cautery is energized for a long time, electric cautery temperature is too high causes.
