Abstract

The utility model relates to an emergency electric-arc electric iron, which is composed of an oscillating circuit, a step-up transformer, a direct-current power supply, a casing, a mica shell, conducting wires, electrodes, an iron head, an insulation layer, etc. The current is input to the oscillating circuit through the low-voltage direct-current power supply, high-frequency alternating-current voltage is obtained after oscillation, and then the current is stepped up through the step-up transformer and is conveyed to the two electrodes. Thus, the air is punctured by the current, arc light is emitted, and a large amount of heat is discharged so that the iron head gives out heat, and weld can be carried out. The preheating time is short, continuous heating is not needed, and the utility model has the emergency function.

Description

Emergent electric arc electric iron

The utility model relates to a kind of electric iron, particularly a kind of emergent electric arc electric iron.

In a single day existing electric iron runs into power failure, just can't carry out welding job.The open-air in addition automotive electronics circuit and the maintenance of the required electronic instrument of field work all make general electric iron be subjected to the influence of power supply.Some low tension flatirons are also arranged, and its heating partly all is to adopt resistance material (as heating wire, carbon etc.); The shortcoming of this class flatiron is; If the resistance of heater is big, then need be through using after the long preheating, the disadvantage that solder horn and various common electrical flatiron are had can appear burning to death; Resistance as heater is little, though immersion heater, operating current is too big, after the battery charge operating period very short, and very easily damage battery.

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and provides a kind of preheating time short, needn't persistent fever, but the emergent electric arc electric iron of saves energy.

The purpose of this utility model can reach by following measure: the utility model comprises shell, mica shell, solder horn, it is characterized in that: also have oscillating circuit, step-up transformer, dc source, electrode, insulating barrier, dc source input oscillating circuit, after vibrating, obtain high-frequency ac voltage, after step-up transformer boosts, deliver to electrode again.

The purpose of this utility model can also reach by following measure: two electrodes are loaded on the place of nearly solder horn in the mica shell, and link to each other with step-up transformer in being loaded on shell by lead, are separated by by insulating barrier between electrode and the solder horn.

Fig. 1 is a functional-block diagram of the present utility model;

Fig. 2 is a structural representation of the present utility model;

Fig. 3 is an electrical schematic diagram of the present utility model.

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):

With reference to Fig. 1, Fig. 2, the utility model is made up of oscillating circuit 1, step-up transformer 2, dc source 3, shell 4, mica shell 5, lead 7, electrode 8, solder horn 9, insulating barrier 10 etc.Electronic circuit board, dc source 3 and step-up transformer 2 can be loaded in the shell 4, and dc source 3 also can provide by external; Two electrodes 8 are loaded on the place of nearly solder horn in the mica shell 5, and link to each other with step-up transformer 2 by two leads 7, are separated by by insulating barrier 10 between electrode 8 and the solder horn 9; Have a plurality of apertures 6 on the mica shell 5.

With reference to Fig. 3, the oscillating circuit that low-voltage dc power supply (12V) input is made up of triode BG1, capacitor C 1～C4, resistance R 1, R2; Obtain high-frequency ac voltage after vibrating, boost through step-up transformer 2, induce the voltage about 4000 volts, this voltage is delivered to two electrodes 8, punctures air, sends arc light, and emits a large amount of heats, makes solder horn 9 heatings, thereby can weld.

The utility model has following advantage compared to existing technology:

1, the preheating time short, can accomplish to use with the opening, needn't persistent fever, saves energy, Improved heat energy utilization etc.

2, heater take up space little, so reduced the danger that irons the body of hurting sb.'s feelings; And also has emergent merit Can, can solve the problem that the occasions such as electrical maintenance when having a power failure, open-air operation exist.
