In the present invention's one preferred embodiment, described flashlight body adopts the good low-carbon alloy steel of heat conductivility to process, and its thickness is about 1.5-2mm.
In the present invention's one preferred embodiment, described flashlight body exterior is coated with protective coating, and its material is PVC, and thickness is about 0.15-0.18mm.
In the present invention's one preferred embodiment; Be provided with thermostat layer between described electrically-heated coil and the flashlight body; What thermostat layer material selection quartz sand, this layer material can make electrically-heated coil adds the heat more even distribution, and can prevent that temperature controller lost efficacy and cause the too high scald human body of temperature.
In the present invention's one preferred embodiment, described temperature controller is used to control the heating-up temperature of electrically-heated coil, and this temperature can effectively be controlled at 50-60 ℃.
In the present invention's one preferred embodiment, be provided with thermal insulation layer and insulating barrier between described electrically-heated coil and the battery successively, thermal insulation layer is used to avoid high temperature that battery is exerted an influence, and guarantees the normal use of battery; Insulating barrier then is used to prevent leaky, improves the security performance of flashlight.
In the present invention's one preferred embodiment, described battery is selected the lead-acid rechargeable pond for use, and its battery capacity is 2000-2500mA.
The present invention has disclosed a kind of warm hand flashlight, and this flashlight structure is reasonable in design, and function is unique, and the built-in electric calorifie installation of cylindrical shell can heat the flashlight body rapidly, and its temperature is risen, and can play good warm hand effect; Simultaneously, this electric calorifie installation is reasonable in design, and is safe in utilization, without any side effects to human body, effectively improves the serviceability of flashlight.
