Patent attributes
A greasy soot purifying device includes a dome bottom in a bearer inside an exhaust pipe of a smoking exhauster, an automobile, a motorcycle and/or a factory which is equipped with a smoking exhausting device, a perforated circular steel plate on the top connected to the bottom by a pair of arcuate conductive rods which is converged with a power source and a temperature sensor disposed on an outer periphery of said bottom. When the greasy soot exhausts through the perforations of the steel plate which produce a temperature up to 500° C., it will be in repeated instantaneous combustion to be gasified and purified as the fresh air and when the temperature becomes higher than the predetermined degree, the temperature sensor will be functioned to break off the electric current until the temperature returned to it predetermined degree.
