Description

Temperature-adjusting type electromagnetic induction heating flatiron

Technical field

The utility model relates to the soldering appliance field, especially a kind of electric iron.

Background technology

Electric iron as soldering appliance, use very common, general flatiron is directly to be inserted in the heating core body sleeve by solder horn, constitute external-heat or inner heating type electric iron, by the heating of heating core body, solder horn is given in the heat conduction then, its temperature control system is a kind of to be the temperature of control heating core, and temperature control is carried out at the middle part or the rear portion of another kind of contact solder horn, during use, thermograde between solder horn tip place and the sensor is bigger, with the solder joint that varies in size, the variation of thermograde is also bigger, and temperature-compensating is also slow, continuous welding speed is carried not high, otherwise has only increase thermal capacity.Improving thermal capacity has two kinds of methods, and the one, improve welding temperature, but scorch wiring board easily, also cause the over oxidation of scolding tin easily, easily form rosin joint, the easier tip of burning solder horn to death, reduction of service life; The 2nd, the volume of increase solder horn, heating power also increases synchronously, and this makes power loss also big.These two kinds of methods all can increase use cost, use also inconvenience, can reduce operating efficiency.For safer, stable in small electronic devices and components and welding, reliable, will design the flatiron of a kind of low temperature, high-power fast compensation at large scale integrated circuit.External existing a kind of electromagnetic induction heating flatiron, be to utilize the electromagnetic induction eddy current heating technique, flatiron by the curie point temperature control of specific alloy material, its shortcoming is that flatiron temperature is to fix from temperature control, and a kind of solder horn assembly is exactly a kind of temperature, the heating part of plating specific alloy and solder horn interlocking, fuse around heater coil, polymeric barrier layer materials, external support pipe again, change together if the replacing solder horn must connect heating core, make use cost very high like this, the scope of application is narrow.

Summary of the invention

In order to overcome the deficiency of existing electric iron, but the purpose of this utility model provides a kind of electric iron of temperature adjustment.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of temperature-adjusting type electromagnetic induction heating flatiron, form by solder horn, electromagnetic type heating core, temperature control sensor, handle and controller, solder horn has heater outward, the solder horn rear end has the hole, be provided with sensor in the hole, the skeleton of electromagnetic type heating core is a support column, the outer high temperature resistant coil of coiling of support column, high temperature resistant coil is provided with screen layer outward, and screen layer is outward the external support pipe.

Further: the support column of described heating core is the stainless steel tube that has groove at the high temperature resistant coil of coiling place.

Further: the ferromagnetism specific alloy layer of the outer plating of described heater solder horn.

Further: the support column of described heating core is non magnetic non-metallic pipe, as alundum tube.

Further: described screen layer is non-closo ferromagnetic metal thin slice.

Further: the external support pipe of described heating core is non magnetic or weak magnetic stainless steel tube, head spot welding back-up ring.

Further: filling is drawn into the stainless steel tube that an end is a blind hole in the hole that open described solder horn rear end, described sensor is by arc-welding of galvanic couple silk or some postwelding, fill in stainless steel tube draw armouring and form very thin shape, the rear portion is connected on the heating core plastic with spring, contacts with solder horn is very tight.

Further: described sensing silk, earth connection, heating core lead-in wire, by the terminal plate in the handle of packing into, link into an integrated entity with connector and controller on line tail, the connecting line, thermoregulation knob is arranged on the controller, be provided with and regulate serviceability temperature.

The utility model is rationally novel in design, and simple in structure, easy to use, the life-span is long, but is a kind of electric iron of temperature adjustment.
