CN2524877Y - Medium and high frequency fast electric iron - Google Patents

Abstract

Under the condition of same power output, an inverse proportion relationship is existed between area of an iron core of a transformer and frequency of an alternating current power supply, which means the higher frequency of voltage of the power supply the smaller area of the iron core of the transformer. Therefore, the utility model comprises a semiconductor frequency converting circuit and a ferrite transformer arranged on a power supply loop of a fast electric iron. The range of working frequency of the transformer is within and ranging from 400HZ to 1000HZ. A medium and high frequency, and low voltage and large current is output by a transformer secondary for a high resistance area of medium and high frequency fast electric iron. The medium and high frequency fast electric iron has fast temperature increasing, melting of tin within ranging from five seconds to ten seconds, small thermal inertia, lighter weight and about 100g and convenient using, and is suitable for the alternating current utility power ranging from 80V to 250V of all the countries.

Description

The medium-high frequency speedy heating iron

Technical field

The utility model relates to a kind of medium-high frequency speedy heating iron, belongs to basic electronic circuit.

Background technology

Existing speedy heating iron on the present market, generally be to make transformer with silicon sheet core, with the 220V electric main, become low-voltage and high-current, supply with the high resistance area heating on the speedy heating iron head, the electric iron of this working method is more many soon than common electrical flatiron programming rate, and need not temperature retention time, advantage with energy savings, still, because a bigger and heavy Industrial Frequency Transformer is arranged, it is very inconvenient that the user feels, very heavy when holding, easily produce fatigue, and be difficult for the finding location is welded.

Summary of the invention

Use heavy transformer defective for solving existing speedy heating iron, way with the rising supply frequency, reduce volume of transformer and weight, because the core area of transformer, be inversely proportional to the frequency of AC power, promptly the frequency of the supply voltage of Qu Donging is high more, the core area of house transformer is more little, the volume and weight of transformer is also just more little, therefore, the utility model is exactly in the electric power loop of electric iron, the semiconductor frequency-conversion circuit is set, other establishes the ferrite transformer of a transform power, and transformer is operated in 400HZ in the 1000KHZ frequency range, the secondary output high frequency of transformer, low-voltage and high-current is given the high resistance area heating of speedy heating iron head; This medium-high frequency electric iron quick heating can melt tin in second at 5-10, and thermal inertia is little, need not be incubated, power saving, and prolong life-span of electric soldering bit greatly, owing to adopt the medium-high frequency power drives, so transformer can be done very for a short time, weight is also very light, can accomplish about 100 grams, and is easy to use, be fit to the electric main 80-250V of various countries, the whole world, and also can be used for direct current.

Description of drawings

Accompanying drawing 1 is an outline drawing of the present utility model.

The specific embodiment

The utility model is in the electric power loop of electric iron, the semiconductor frequency-conversion circuit is set, and establish the ferrite transformer of transform power in addition, transformer is operated in 400HZ in the frequency range of 1000KHZ, transformer secondary output, output high frequency, low-voltage and high-current are given the high resistance area heating of speedy heating iron head; See also shown in the accompanying drawing 1, one end of the utility model handle 1 is equipped with solder horn 4, and there is power switch 5 in handle 1 outside, inner at handle 1 near the first end of flatiron, medium-high frequency transformer 3 is housed,, semiconductor inverter circuit board 2 is housed at the bosom of handle 1, high frequency inverter circuit on this semiconductor inverter circuit board 2, to import supply frequency and be transformed to 400HZ to 1000KHZ, and deliver to medium-high frequency transformer 3, the secondary and solder horn of intermediate-frequency transformer 3 is connected.
