CHARCOAL BED FOR BLOCKING ELECTROMAGNETIC WAVE AND PURIFYING AIR BY USING ELECTROMAGNETIC WAVE ABSORBING AND FILTERING DEVICE

摘要

PURPOSE: A charcoal bed for blocking electromagnetic wave and purifying air is provided to remove bad smell by decomposing various kinds of toxic gases. CONSTITUTION: A charcoal bed for blocking electromagnetic wave and purifying air comprises an upper plate(110), an electromagnetic wave absorbing and filtering device, a hardwood charcoal receiving chamber, a temperature controller, and a controller. A plurality of upper plate form one group and are installed while being divided. The electromagnetic wave absorbing and filtering device absorbs and removes electromagnetic wave. The hardwood charcoal receiving chamber emits negative ion around user's head. The temperature controller controls the heat temperature of a carbon heater. The controller controls the temperature of the carbon heater according to the set value of the temperature controller.
