Abstract
The utility model discloses a heating core of a hot air gun. The heating core of the hot air gun comprises an air pipe fixedly arranged at the front side of a fan, and a plurality of mica sheets are arranged in the air pipe. The mica sheets are radially and evenly arranged in the air pipe. One ends of the mica sheets are fixed with the air pipe, and the other ends of the mice sheets are arranged on the same mica support frame in an inserted mode. Electric heating wires are wound on the outer sides of mica sheets. A plurality of grooves are arranged along the edges of the outer sides of the mica sheets, and the heat electric heating wires are arranged in the grooves in an embedded mode. The mica sheets are 3to 8 in number. The heating core of the hot air gun can be rapidly arranged at the front side of the fan, wind resistance in the air pipe is small, and air outlet quantity of the same power is large. A thermal fuse mainly takes a protection role, the safety problem due to high temperature is prevented when the heating core of the hot air gun works for a long time, and therefore burning is avoided. The heating core of the hot air gun has the advantages of being simple in structure, rapid in warming in start-up, precise in temperature, stable in performance and good in heat dissipation, and has good market prospects.
Description
Technical field
The utility model relates to a kind of electric calorifie installation, specifically a kind of heat generating core for heat gun.
Background technology
Electron trade develop rapidly in recent years, the welding electronic component heat gun also receives publicity day by day, heat gun is mainly to utilize the hot blast that the rifle core of heating resistance wire blows out that element is welded and the instrument of winning element, and heat generating core is most important part in heat gun.Poor heat generating core temperature is unstable, and is fluctuated, and what during start, temperature was given birth to is very slow, and several minutes, then the temperature straight line rose, and will burn out unless you give your whole attention to it, has very large potential safety hazard.Patent Office of the People's Republic of China is disclosed on April 8th, 2009, the patent No. is 200820068137.0 ceramic heating core of hot air gun, it is to have the ceramic heating tube of Electric radiant Heating Film parallel with one another by two surfaces that vary in size and inwall, then be fixed on same micarex support together with ceramic heating tube that the surface has certain resistance value Electric radiant Heating Film, both be connected in parallel by temperature controller.The ceramic heating tube section of this heat generating core is larger, therefore can increase the windage in airduct.
The utility model content
The purpose of this utility model is for the defective of above-mentioned prior art and deficiency, for people provide a kind of simple in structure, start quick heating, temperature accurately, stable performance, good heat dissipation, heat generating core that windage is little, be used for heat gun.
Technical solution adopted in the utility model is for achieving the above object: this heat gun heating core, it comprises the airduct that is fixedly installed in the blower fan front side, the polylith mica sheet is installed in described airduct, mica sheet is radially uniform in airduct, one end and the airduct of mica sheet are fixed, the other end is plugged on same mica support, has installed around heating wire in the outside of mica sheet.
The outer side edges of described mica sheet is along offering a plurality of grooves, and heating wire is flush-mounted in groove.
Described mica sheet is 3 to 8.
Be provided with one deck mica paper between described airduct and heating wire.
Described heating wire is connected with power switch by after thermal cut-off.
The utility model can Fast Installation in the front side of blower fan, the windage in airduct is less, same power air output is larger.Thermal cut-off mainly shields, and when preventing from working long hours, excess Temperature causes safety problem and burns out.Have advantages of simple in structure, start quick heating, temperature accurately, stable performance, good heat dissipation, good market prospects are arranged.

The specific embodiment
Show as Fig. 1, Fig. 2, the utility model is a kind of this heat gun heating core, and it comprises the airduct 7 that is fixedly installed in the blower fan front side, and blower fan comprises motor 8, motor cabinet 9, fan blade 10 and air-ducting ring 11, and airduct 7 is fixed by screw with the air-ducting ring 11 of blower fan.Also pad is equipped with airduct pad 6 between airduct 7 and air-ducting ring 11, in case leak-stopping wind.In described airduct 7, polylith mica sheet 3 is installed, mica sheet 3 is radially uniform in airduct 7, and an end of mica sheet 3 and airduct 7 are fixing, and the other end is plugged on same mica support 4, and mica sheet 3 is installed firmly.Installed around heating wire 2 in the outside of mica sheet 3, the wind that enters in the airduct will blow out hot blast after the heating wire 2 through heating.Described mica sheet 3 is 3 to 8, so that heating wire 2 is supported.The outer side edges of described mica sheet 3 is along offering a plurality of grooves 3.1, and heating wire 2 is flush-mounted in groove 3.1, can prevent that heating wire 2 from sliding.Be provided with one deck mica paper 5 between described airduct 7 and heating wire 2, be mainly used in insulation with heat insulation.Described heating wire 2 is connected with power switch 12 by thermal cut-off 1 is rear, and thermal cut-off 1 plays a protective role, and when preventing from working long hours, excess Temperature causes safety problem and burns out.
The utility model can Fast Installation in the front side of blower fan, the windage in airduct 7 is less, same power air output is larger.Thermal cut-off 1 mainly shields, and when preventing from working long hours, excess Temperature causes safety problem and burns out.Have advantages of simple in structure, start quick heating, temperature accurately, stable performance, good heat dissipation, good market prospects are arranged.
