Description

Heating core assembly and hot air gun Technical Field The utility model relates to the field of electric tools, in particular to a heating core assembly and a hot air gun. Background The hot air gun is a heating tool for forming hot air flow after heating air, and has various use functions, and particularly, the hot air gun can be used for removing old paint on the surface of metal, removing self-adhesive sticker, heating plastic rubber tube to bend, drying wet wood, heating to thermally shrink packaging film and packaging tube, derusting, heating polyethylene used for connecting metal to shrink and heat to soften welded materials, and the like, and can also be used for welding or removing elements by utilizing hot air flow blown out by a gun core of a heating resistance wire. At present, the channels of heating wire brackets on the market are all straight channels, and the flow channel of air in the channels is shorter, so that the heating time of the air is insufficient, the temperature of the guided air is low, the heat efficiency is low, the expected working effect cannot be well achieved, and the working efficiency of the heat gun is reduced. Disclosure of utility model The utility model aims to overcome the defects in the prior art, can effectively solve the problem that flowing air in the prior art is rapidly dissipated in the air after passing through a heating bracket channel, and provides the hot air gun with higher efficiency and convenience. The utility model is realized by the following technical scheme: The utility model provides a core subassembly generates heat for air heating device, core subassembly generates heat includes support and heating element, the support has air intake, air outlet and connects the passageway of air intake and air outlet, heating element locates in the passageway, its characterized in that, the passageway extends along predetermined smooth curve for the length of passageway is greater than the lengthwise of support, is heated by heating element when the air passes through the passageway, and the curve passageway has increased the length of passageway, improves hot-blast heating efficiency. Further, the number of the channels is 2-10, and the channels are uniformly distributed. Further, the cross section of the channel is always circular. Furthermore, the bracket is made of ceramic or mica, and the ceramic or mica has higher heat resistance. Furthermore, the channels are independently arranged and are not communicated with each other, and hot air is blown out from the air outlet after entering from the air inlet. Further, the heating element is in a coil shape or a bulk shape. Further, the channel is configured in a spiral shape. Further, the heating element includes a tight-wound section having a length less than the length of the channel. Further, the included angle between the air inlet and the air outlet is 20-120 degrees. The utility model provides a hot air gun, includes the shell, is equipped with the hot air device that produces hot air in the shell, and hot air device includes the core subassembly that generates heat, and the shell front end is equipped with the hot-blast main, and the core subassembly that generates heat is located the hot-blast main. Compared with the prior art, the utility model has the following beneficial effects: According to the utility model, the curve-shaped heating channel is arranged, the heating element is arranged in the channel, and the air outlet distance of the hot air gun is increased by increasing the length of the channel, so that the heating efficiency is improved, the structure is simple, the operation is more convenient, and the working efficiency is greatly improved.
