The heater can wind a heating wire on a high temperature ceramic pipe, a high temperature insulation ceramic pipe can be sheathed out of the heating wire, and therefore, the heat of the electric iron is concentrated and the temperature raising is rapid with adopting the heating wire winding technique. The utility model has remarkable energy conservation effect without power supply control, and the power consumption is only 1/3 of the power consumption of inner-heat type soldering irons. Meanwhile, the utility model has the advantages of short pre-heating time, long service life, simple structure, easy manufacturing, low cost and multiple power grades, which can also be made into a low-voltage DC supply iron.

Description

High-efficiency energy-saving electric soldering irons

The utility model is the improvement to electric iron, relates to the welding specialty.

Electric iron has had significant improvement in recent years, and the energy-saving electric iron of various ways emerges one after another.Wherein have plenty of and adopt the way of heating element heater near copperhead, the employing that has is the mode of time spent outage not, the mode of the intensive spaced winding of employing heating wire that has.Though it is the energy-saving effect of these three kinds of electric iron increases, also not very high.It is close around technology to disclose a kind of pen type electric iron heating wire in (application number 89200512.2) " a kind of pen type energy-saving electric iron " utility model patent of my application, additional supply control technology not, just can make the energy consumption of pen type electric iron reduce by 2/3, energy-saving effect is considerable.But not enough is that this application only limits to the pen type electric iron, narrow application range, and for the user who does not have electricity or the normal district that has a power failure, and do not have superiority.

The purpose of this utility model is that " a kind of pen type energy-saving electric iron " improved, and makes its power grade many, and range of application is wide, even applicable to the high-efficiency energy-saving electric iron of non-Electric region.

The utility model mainly is to be applied to general electric iron around technological expansion the heating wire in " a kind of pen type energy-saving electric iron " is close, and its thermal efficiency is improved.Its concrete structure is that heating wire (5) is close on high temperature porcelain tube (8) shown in Fig. 1,2 and 3, its high-temperature insulation porcelain tube of outer suit (4), and the back embeds the rear portion of the copperhead (1) of flatiron, and copperhead is similar to the copperhead of general inner heating type electric iron.For fear of the copperhead oxidation, can be coated with one deck heat resistance paint in the part of copperhead except that the working end.Thermal packer (2) between copperhead and the handle (3) adopts thin-walled garden, rustless metal pipe, it can be a stainless steel, can be that thin-wall steel tube adds coating, also can be other metals that are difficult for getting rusty,, specifically use which kind of metal material as aluminium alloy etc., look the power and the size of electric iron, around the tube wall of metal garden pipe a plurality of louvres (10) are arranged, from easy to process, it can be hole, garden or oblique slot type hole.For example, beat triplex row, every row is beaten a plurality of holes.Good for what copperhead is connected with Thermal packer cooperate, can extrude 3～4 rubber-likes, half garden arc convex (9) at the copperhead afterbody, and its catercorner length is slightly larger than the internal diameter of instlated tubular, so that instlated tubular is inserted in and tightens.Handle can be made the multiple moulding of being convenient to hold, but should there be the hole at its center, so that lead is passed, or for the low power electric iron dress commutation diode of holding concurrently therein, or during for no civil power district employing dry cell power supply, is battery case with the double as.In this case, as shown in Figure 4, to there be the battery utmost point (11), switch (12), afterbody that battery case lid (13) is arranged in the handle, with switch control electric iron duty.Handle and Thermal packer can be connected, and also can use screwed connection, and for convenient, the latter will have collets (6) and binding post (7) at the Thermal packer afterbody.

Employed heating wire is close around technology in the utility model, is different from conventional spaced winding or intensive spaced winding, but real intensive winding, promptly the electrothermal wire coil with enclose between near, do not stay the gap.This winding is commonly considered as not all right, thinks and can cause short circuit.Facts have proved it is that no.Through processing many electric iron on probation, not only do not have short circuit problem, and the thermal efficiency is very high.Because heater dwindles length, more close copperhead working end, the heat of generation is concentrated, quick heating, the heat that same power consumption produces is big, equals to have reduced energy consumption comparatively speaking.Thermal packer adopts metal tube, though a little than the wire weak heat-dissipating, general electric iron stature size is not a major issue, does not require that Thermal packer is very short.High-power electric iron, copperhead are also big, then require Thermal packer that certain intensity is arranged, and are suitable so use metal tube.

China also has the no mains supply in many rural areas or remote districts at present, also have many areas often because of the not enough situation that causes frequent power failure of supply of electric power, now the electric iron of city's pin all adopts the alternating current 220V power supply, for not having electricity or the normal district that has a power failure, is not that can't to carry out the work be exactly to wait electric could work.This brings many inconvenience for the maintenance of many electrical maintenance departments or field work equipment.For head it off, heat is big owing to can accomplish to consume energy little for the utility model, so the possibility of using dry cell, battery, nickel-cadmium cell has just been arranged.Certainly, because the finite capacity of current dry cell can only be made some lower-powered electric iron, solve the problem of smallclothes soldering.This kind electric iron is pressed rated power, as long as design the length of heating wire.As for electric power system, can be designed to GENERAL TYPE, special battery case is arranged, during use the flatiron plug is inserted on the accessory power outlet of battery.Also can be designed to portablely, battery is contained in the handle, and this just requires that battery case, electrode and lead-in wire are arranged in the handle.

This high-efficiency energy-saving electric iron since Thermal packer can do longer, so can make powerful electric iron.In general, accomplish that 150W is fully out of question.Then can accomplish 1.5W toward little.Just when small-power, need in the supply line of alternating current 220V, be connected in series a commutation diode, make the voltage that is added on the heating wire become the half-wave shape, be equivalent to step-down and use.

The utility model is structurally also uncomplicated, and is very close with old-fashioned inner heating type electric iron, but owing to adopted heating wire close around technology, its effect is fine.Its main feature is simple in structure, handling ease, low price; Give hot time weak point, about 40～45 seconds; Power consumption only is 1/3 of an old-fashioned inner heating type electric iron power consumption, and energy-saving effect is very obvious, if be equipped with power control switch again, flatiron is only just powered up when work, and energy-saving effect is just better so; This flatiron long service life, general minimum more than 4000 hours; This electric iron can be designed and manufactured into many power grades series of products of 1.5～150W at an easy rate, to satisfy the needs of different user, especially can also make the electric iron that uses low voltage and direct current, for the needs of non-Electric region.
