Abstract

The utility model relates to a novel electric soldering iron, which comprises a copper head, a heating part, a housing, leads, a handle and a power plug, wherein the heating power consists of outer-layer mica, electric heating wires and inner-layer mica, and the inner-layer mica is wound and wrapped around the copper head; and the surface of the inner-layer mica is wound with the electric heating wires, and the outer-layer mica is wound and wrapped around the electric heating wires. After the electric soldering iron is electrified, resistance wires are heated, so that the heat is transferred inwards to the inner-layer mica, is transferred to the heated part of the copper head by the inner-layer mica, and then is transferred to the top end of the copper head by the copper head, and then the tin fusion soldering is carried out. The utility model has the advantages of ingenious process, simple operation, reasonable structure and the like.

Description

New-type electric iron

Technical field the utility model relates to a kind of soldering appliance, especially a kind of new-type electric iron.

Background technology is well-known, and electric iron is people's one of instruments of the most normal use in welding job.At present, it is copperhead that the center with existing electric iron heating part was once arranged, and copperhead is inserted in the earthenware, and the outer bread of earthenware heating wire, and heating wire is surrounded by mica paper and external insulation outward.This kind structure is after energising, and resistance wire can produce a large amount of heats, and heat energy is delivered to the part that is heated of copperhead to internal delivery through earthenware and air gap, and copperhead is passed to the top to heat, and just fusible soldering this moment connects.Yet the copperhead of electric iron is selected red copper for use, and red copper is worked under higher temperature and understood and air generation oxidation reaction, generates the iron oxide of black, influences welding effect and precision; In addition, the thermal conductivity factor of earthenware is 1.32W/m.k, and the thermal conductivity factor of air is 0.263W/m.k, and thermal conductivity factor is low, and it is just low to wear the thermal efficiency, and increase the preheating time of therefore working, and influences operating efficiency.In order to address the above problem, we provide a kind of new-type electric iron very necessary.

The summary of the invention the purpose of this utility model provides a kind of new-type electric iron, is used to solve that common electrical flatiron heat transfer efficiency is low, preheating time is long, oxidation easily, service life is short, continuous working period is short and be difficult for problem such as tining.

For achieving the above object, the new-type electric iron of the utility model comprises copperhead, heating part, outer cover, lead, handle and attaching plug, and described heating part is made up of outer mica, heating wire, internal layer mica; The internal layer mica twines the parcel copperhead, and heating wire is wrapped in the internal layer mica surface, and outer mica twines and wraps heating wire.

After adopting said structure, the centre is a copperhead, and the copperhead outside is surrounded by one deck mica, and mica teases heating wire outward, and heating wire has one deck mica and external insulation outward again.After the electric iron energising, the resistance wire heating, heat energy inwardly is delivered to the internal layer mica, and the internal layer mica is the be heated part of thermal energy transfer to copperhead, and copperhead arrives the copperhead top to thermal energy transfer, and then molten soldering connects.

Copperhead heating part outside is surrounded by one deck mica, and mica paper is close to the outside of copperhead, and copperhead and air insulated are opened, and effectively solves the problem of the easy oxidation of copperhead.

The heat energy that heating wire produces inwardly passes to mica; mica is given copperhead thermal energy transfer; the thermal conductivity factor of mica is 2.77W/m.k, compares with existing electric iron, and the temperature of copperhead heating part will be hanged down 100 ℃; and the temperature of copperhead end will exceed 90 ℃; this is because the thermal conductance that the FH-1 electric iron can produce heating wire is rapidly come out, and has so both protected heating wire, and the temperature of copperhead end is raise; heat transfer efficiency improves greatly, has prolonged the service life of electric iron.

Compared with the prior art, the beneficial effects of the utility model are: technology exquisiteness, easy to operate, rational in infrastructure, safe and reliable, adopting conducts heat is close to mode, shorten preheating time, improve heat transfer efficiency, and continuous working period is long, shock resistance is strong, and can slow down oxidation, increases the service life, and facilitates, service condition efficiently.

Description of drawings Fig. 1 is the overall structure schematic diagram of the new-type electric iron of the utility model.

Fig. 2 is the heating part sectional view of the new-type electric iron of the utility model.

Number in the figure: 1 is that copperhead, 2 is that heating part, 3 is that outer cover, 4 is that lead, 5 is that handle, 6 is that attaching plug, 7-1 are that outer mica, 7-2 are that internal layer mica, 8 is a heating wire.

The specific embodiment as shown in Figure 1, the new-type electric iron of the utility model comprises copperhead 1, heating part 2, outer cover 3, lead 4, handle 5 and attaching plug 6, described heating part 2 is made up of outer mica 7-1, heating wire 8, internal layer mica 7-2; Internal layer mica 7-2 twines parcel copperhead 1, and heating wire 8 is wrapped in internal layer mica 7-2 surface, and outer mica 7-1 twines and wraps heating wire 8.
