Description

The electric iron structure

Technical field

The utility model relates to industrial electronics technical field of tools, is specifically related to a kind of welding electric iron structure.

Background technology

Electric iron be the birth time at most, use the most universal, still a large amount of universal electric instruments that use so far.It has the series of products of multiple size and model, and rated disspation does not roughly wait from 25 watts to hundreds of watts.Main application is by the electric heating transfer principle solder horn to be heated up to melt the soldered component side of scolding tin, heating, finally to make each element welding or separate.

The solder horn of the common electrical flatiron that is widely used at present (especially high-power flatiron) is all relatively long, the part that stretches in the flatiron head-shield is also longer, the purpose that make sound construction to reach, increases area of heat transfer between solder horn and the heat generating core, but still there are many drawbacks in present this electric iron structure, for example intensification is fast inadequately, the solder horn life-span is not long, and utilization rate of electrical is very low.

The electric iron of this flatiron head length height that not only consumes energy, and in the welding or the work of disassembling, operator's one hand is held on the handle of flatiron postmedian, and makes solder horn tip (being the weld heating face) keep stable as far as possible.If operator's hand has small rocking, because this length of rocking by electric iron of lever principle will be exaggerated several times in the solder horn tip, causing can't normal running so.This just requires the operator and to become sophisticated skilled worker's ability normal running electric iron through certain training.Many hands can not keep the therefore not competent precision even the common electric iron welding job of operator of highly stable state under the situation of exerting oneself, therefore flatiron operator technical threshold and training cost become very important.

Existing in addition electric iron is because warm-up time is long, and solder horn and electrothermal tube long-term work are under the condition of high temperature.Like this components and parts be easy to wear out, oxidized or corroded by scaling powder, also can directly cause electric iron to damage, increase the part exchanging rate, make that production cost continues to rise.

Moreover existing electric iron is generally controlled duty and temperature by switch or diode.This power managed main source also depends on the operating efficiency of control circuit, can not improve existing drawback from the agent structure of electric iron.Though some electric iron production firms have adopted temperature control method to manage the temperature and the power consumption of electric iron, but because cost is higher relatively and practical operation influences unconspicuous cause, the actual power loss efficiency of management of this constant temperature/temperature adjustment electric iron is not high, and does not have by extensively a large amount of uses to cut down the consumption of energy.The very low outstanding problem that remains electric iron of energy utilization rate.

The utility model content

Problem to be solved in the utility model provides the electric iron structure that a kind of volume is little, easy to operate and energy consumption is low.

For the technical scheme that solves the problems of the technologies described above the utility model realization is:

Design a kind of electric iron structure, include the flatiron housing, the temperature sensor that is provided with electrothermal tube in the flatiron housing and detects the electrothermal tube heating temp, electrothermal tube, temperature sensor are connected with controller by electrothermal tube lead-in wire, temperature sensor wires respectively, described electrothermal tube also is connected with solder horn, described solder horn is nested with outside electrothermal tube, and the length of electrothermal tube is not more than 15mm.

The utility model compared with prior art has following remarkable result:

Electrothermal tube that the length that the utility model adopted is very short and the less miniature type soldering iron head of size that electrothermal tube is placed in one, reducing significantly on the flatiron overall structure can the heat conductive metal consumption, reduce the integrally-built temperature inertia of electric iron, does not finally reach not influencing fully to realize energy-efficient on the former powerful basis of electric iron and reduce the consumption reduction effect of metal material consumption significantly.Because the solder horn volume of heat conduction reduces significantly, according to the notion of material specific heat capacity as can be known, electric energy power consumption required when the microprint solder horn is warming up to uniform temp will reduce significantly, can reduce the required time of heating up simultaneously.The electric iron volume of realizing with this structure is little, easy operating uses, and also reduces the probability that the operator is scalded by flatiron accidentally simultaneously greatly.In addition, this modified electric iron structure can be used with multiple simple control circuit, further reduces energy consumption, improves the availability of electric energy.
