Patent attributes
The present invention is an aromatic evaporator consisting of a base, a heater, a heat conduction aluminum plate, a constant temperature controller, a plug, a ceramic carriers and a cover. The plug sets inside the base to deliver D.C. power; the heater converts the electricity from the plug into heat; the heat conduction aluminum plate adhered to the heater directly evens the heat; the constant temperature controller contains the electric conduction switch and the memory alloy plate connected with the heat conduction aluminum. When the memory alloy plate is straight, the electric conduction switch is switched off and stops the heater from heating. When the temperature reduces, the memory alloy plate is curved by external force and switches on the electric conduction switch, making the heater reheat. The memory alloy plate of the constant temperature controller controls the heater to heat intermittently, making the heater heat at constant temperature.
