Abstract
The invention discloses a 3D drawing pen and a high temperature warning method. As both a temperature warning indicator and a temperature sensor which is arranged in a pen head cavity are connected with a control circuit, trigger warning temperature and ultra-high temperature warning temperature can be configured accordingly; once the real-time work temperature of the drawing pen is higher than the trigger warning temperature and is lower than the ultra-high temperature warning temperature, the control circuit controls the temperature warning indicator to turn from green to orange and flash at interval, so as to warn an operation user; once the real-time work temperature of the drawing pen is greater than the ultra-high warning temperature, the control circuit controls the temperature warning indicator to turn red and flash at shorter interval, and controls a heating part to stop heating, so that the use safety of the drawing pen is improved. Furthermore, the consumables of the 3D drawing pen are led in through a high temperature resistant plastic pipe the melting point of which is higher than that of the consumables, thus the problem that an expansion pipe is blocked due to thermal energy transmission in a lead-in through hole before the consumable enters a nozzle to be heated and melted is solved and the selection scope of 3D printing consumable is enlarged.
