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.

Description

technical field [0001] The invention relates to a 3D printing device, in particular to a 3D drawing pen and a warning method thereof. Background technique [0002] The 3D drawing pen needs to heat and melt the consumables for artistic creation during the working process. In order to achieve a fast and uniform heat dissipation effect, the traditional fan heat dissipation is gradually replaced by the pen head integrated heat sink and heat dissipation holes. However, due to the heat conduction effect of the heating device and heat dissipation equipment, the consumables are easy to heat and expand in the stainless steel through-hole before entering the nozzle to be heated and melted. Therefore, the expansion tube of the 3D drawing pen often becomes blocked during the working process, which seriously interferes with artistic creation. continuity. When the user is interrupted by the blockage of the expansion tube during the creation process, because there is no intuitive and accu...
