Abstract

The utility model provides an electric iron keeps warm and prevents burning to death device, its characteristic includes: 220V alternating current power supply, electric iron operating voltage converting circuit and electric iron socket. The practice shows: electric iron most of the time work is at ohmic heating state in succession, and the time that really uses the electric iron is little, and the soldering iron oxidation of electric iron is burnt to death in other words, the flatiron core burns out is because the electric iron is switched on for a long time, electric iron high temperature and leading to, in addition, the soldering iron is not only burnt easily to death to the high temperature of electric iron, and the soldering iron of just burning to death is difficult for eating tin, causes the electric iron not handy. Electric iron keeps warm and prevents burning to death device can effectively solve these problems, it need not active electronic components, only uses fuse, 2 2 double -pole double -throw, incandescent lamp and socket commonly used, through changing cluster, parallel connection mode, the electric iron can be realized heating or heat retaining effect, has stopped to burn out because of the high temperature phenomenon of electric iron basically.

Description

Electric iron insulation is anti-burns device to death

Technical field

The utility model belongs to electronic technology and temperature control technology field, is to burn device to death about a kind of electric iron insulation is anti-.

Background technology

The various electric iron that market is sold never have any basic change.At the various electrical equipment of repairing, during electronic equipment, usually need by instrument measurement circuit, analysis of failure, collating elements, electric iron is in always and adds hot standby state during this period, and it works total head "on" position always.Practice shows: the electric iron most of the time is operated in laser heating state, and the time really using electric iron welding is little, and this causes the main cause that the oxidation of the solder horn of electric iron is burnt to death, iron core burns out, electric iron temperature is too high; In addition, the temperature of electric iron is too high not only easily burns solder horn to death, and the solder horn burnt to death not easily eats tin, causes electric iron not handy.

Electric iron insulation described in the utility model prevents that burning device to death can effectively address these problems, and it is without active component, only uses fuse, conventional 2 × 2 double-point double-throw switch, incandescent lamp and supply socket, by changing series and parallel connected mode; Insert electric iron in electric iron socket after, namely realize the effect of heating or being incubated, substantially stopped Yin Wendu too high and burn out the phenomenon of electric iron, it achieved the object extending electric iron service life.

Below describe in detail electric iron described in the utility model insulation anti-burn to death device necessity involved in implementation process, guardian technique content.

Utility model content

Goal of the invention and beneficial effect: practice shows: the electric iron most of the time is operated in continuous electrified regulation state, the time really using electric iron is little, in other words the solder horn oxidation of electric iron burn to death, iron core burn out be due to electric iron be energized for a long time, electric iron temperature is too high and cause; In addition, the temperature of electric iron is too high not only easily burns solder horn to death, and the solder horn burnt to death not easily eats tin, causes electric iron not handy.Electric iron insulation described in the utility model prevents that burning device to death can effectively address these problems, and it is without active component, only uses fuse, conventional 2 × 2 double-point double-throw switch, incandescent lamp and socket, by changing series and parallel connected mode; Insert electric iron in electric iron socket after, namely realize the effect of heating or being incubated, substantially stopped Yin Wendu too high and burn out the phenomenon of electric iron, it achieved the object extending electric iron service life.

Circuit working principle: electric iron insulation is anti-burns device to death without active component, only uses fuse, 1 conventional 2 × 2 double-point double-throw switch, 1 incandescent lamp and electric iron socket, by changing series, parallel connected mode; Insert electric iron in electric iron socket after, namely realize the effect of heating or being incubated, it can extend the object in electric iron service life.

Electric iron socket CZ, incandescent lamp HL lamp socket and power switch K1 and double-point double-throw switch K2 are fixed on the correct position of insulation board plate, then according to connection mode in accompanying drawing 1, and carefully connect and weld, make moveable power patch panel.

In use, switch on power K switch 1, and power patch panel obtains electric, and electric iron inserts in electric iron socket CZ, and when double-point double-throw switch K2 is placed in position in parallel, incandescent lamp HL is entirely bright, now electric iron Fast Heating work under 220V alternating current total head.When double-point double-throw switch K2 is placed in another location, incandescent lamp HL (25 ~ 60W) is connected in electric iron performance loop, and incandescent lamp HL brightness is dimmed; Now, electric iron place under low pressure can work long hours, and this just makes electric iron play insulation effect, and electric soldering bit is also not easily scorched to death.

Technical characteristic: electric iron insulation is anti-burns device to death, and it comprises 220V AC power, electric iron operating voltage change-over circuit, electric iron socket, it is characterized in that:

Electric iron operating voltage change-over circuit: the live wire end L of 220V AC power connects the 3rd pin of double-point double-throw switch K2 and one end of electric iron socket CZ by power switch K1, fuse BX, 4th pin of another termination double-point double-throw switch K2 of electric iron socket CZ and the common port com1 of double-point double-throw switch K2, the zero line side N of 220V AC power connects the 1st pin of double-point double-throw switch K2 and one end of incandescent lamp HL, the 2nd pin of a termination double-point double-throw switch K2 of incandescent lamp HL and the common port com2 of double-point double-throw switch K2.

Accompanying drawing explanation

Accompanying drawing 1 is the anti-circuit working schematic diagram burning a device embodiment to death of electric iron insulation that the utility model provides.

Detailed description of the invention

Device circuit fundamental diagram and accompanying drawing explanation is burnt to death according to the electric iron insulation shown in accompanying drawing 1 is anti-, and according to annexation between components and parts in each several part circuit described in utility model content, and components and parts technical parameter described in embodiment requires and circuit production main points are carried out enforcement and can be realized the utility model, is further described correlation technique of the present utility model below in conjunction with embodiment.
