Abstract
The utility model discloses an electric soldering iron adjustable in temperature. The electric soldering iron comprises a welding head, a soldering iron core and an outer shell which are sequentially arranged in a sleeved mode, the outer shell is connected with a handle through a connecting piece, a bracket is arranged in the handle, the bracket is provided with an integrated circuit board, a sliding thermolator and a heat transfer piece, the integrated circuit board is respectively and electrically connected with the sliding thermolator and the heat transfer piece, one end of the heat transfer piece is connected with the outer shell, and the handle is provided with a switch corresponding to the sliding thermolator. When the integrated circuit board is powered on, heat is transferred to the welding head through the heat transfer piece; when the welding head operates for a long time, the sliding thermolator is regulated, the temperature of the heat transfer piece is regulated by regulating the magnitude of an output circuit of the integrated circuit board, and the temperature of the welding head is further regulated.
Description
Technical field
The utility model relates to electric iron technical field, particularly a kind of temperature adjustable electric flatiron.
Background technology
Electric iron is electronic production and electrical maintenance instrument, main application is welding machine element and wire, by structure, can be divided into inner heating type electric iron and external heated electric iron, by function, can be divided into used for welding flatiron and inhale tin electric iron, according to purposes difference, being divided into again high-power electric soldering iron and small power electric flatiron.Existing electric iron generally comprises solder horn, iron core and is sheathed on the shell on iron core, and shell is connected with handle, produces high temperature heating during work after iron core energising, and heat is conducted to solder horn.Yet existing electric iron in use As time goes on, and the temperature of iron core and solder horn can be more and more higher, because temperature cannot regulate, greatly reduce the service life of electric iron.
Utility model content
The purpose of this utility model is for the defect of prior art and deficiency, and a kind of simple and reasonable, easy to operate, temperature adjustable electric flatiron that can improve service life is provided.
For achieving the above object, the utility model is by the following technical solutions:
A kind of temperature adjustable electric flatiron described in the utility model, comprise sheathed successively solder horn, iron core and shell, described shell is connected with handle by connector, in described handle, be provided with bracket, described bracket is provided with surface-mounted integrated circuit, slip thermosistor and heat transfer sheet, described surface-mounted integrated circuit is electrically connected to slip thermosistor, heat transfer sheet respectively, and described heat transfer sheet one end is connected with described shell, and described handle is provided with the switch corresponding with described slip thermosistor.
Further, on described shell and iron core, correspondence position is equipped with lockhole.
Further, on described bracket, be also provided with some steady terminals.
Further, described handle is provided with silica-gel antiskid cover.
The beneficial effects of the utility model are: surface-mounted integrated circuit and slip thermosistor are set on bracket, during surface-mounted integrated circuit energising, by heat transfer sheet, heat is reached to solder horn, when the solder horn working time is longer, regulate slip thermosistor, can pass through the size of surface-mounted integrated circuit regulation output circuit, adjust the temperature of conducting strip, and then regulate the temperature of solder horn.
Accompanying drawing explanation
Fig. 1 is blast structural representation of the present utility model.
In figure:
1, solder horn; 2, iron core; 3, shell; 4, connector; 5, handle; 6, bracket; 7, slip thermosistor; 8, heat transfer sheet; 9, switch; 10, lockhole; 11, steady terminal; 12, silica-gel antiskid cover.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
A kind of temperature adjustable electric flatiron as shown in Figure 1, comprise sheathed successively solder horn 1, iron core 2 and shell 3, described shell 3 is connected with handle 5 by connector 4, in described handle 5, be provided with bracket 6, described bracket 6 is provided with surface-mounted integrated circuit, slip thermosistor 7 and heat transfer sheet 8, described surface-mounted integrated circuit is electrically connected to slip thermosistor 7, heat transfer sheet 8 respectively, and described heat transfer sheet 8 one end are connected with described shell 3, and described handle 5 is provided with the switch 9 corresponding with described slip thermosistor 7.
After surface-mounted integrated circuit energising, electric current is reached to heat transfer sheet 8, under the fuel factor effect of electric current, heat transfer sheet 8 heatings also reach shell 3 by heat, and shell 3 and iron core 2 are all that hot good conductor material forms, and solder horn 1 can heat up rapidly, when the working time is longer, by switch 9, regulate slip thermosistor 7, the output current of surface-mounted integrated circuit is reduced, and then reduced the temperature of solder horn 1, avoid solder horn 1 at high temperature to work for a long time, improved service life of the present utility model.
On described shell 3 and iron core 2, correspondence position is equipped with lockhole 10, for fixing solder horn 1.On described bracket 6, be also provided with some steady terminals 11, be convenient to prevent power line.Described handle 5 is provided with silica-gel antiskid cover 12.
The above is only preferred embodiments of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
