Abstract

The utility model relates to an illuminating electric iron, which comprises an iron head, an iron core, a handle holder, a handle and a power line, and is characterized in that a LED is arranged to illuminate against the iron head at an outer end where the handle holder is connected with the iron core, the circuit connecting method is that each LED is connected with the iron core in series after connected with a down resistor in parallel; when the light of a working face is insufficient, the LED on the end of the handle holder can effectively illuminate the head part of the iron head, for the LED is connected with a storage battery, so when power supply is cut off, the LED can be used as an emergency lighting function. The utility model does not need to change the original shape of an electric iron, so the structure is simple.

Description

The electric iron that can throw light on

Technical field

The utility model relates to a kind of electric iron, particularly a kind of electric iron that throws light on.

Background technology

The electric iron of Chu Shouing mostly is traditional electric iron in the market, generally is made up of solder horn, iron core, handle and power line, and power line is electrically connected with iron core.Heating after the iron core energising is transmitted on the solder horn then, satisfies the temperature required needs of solder horn, by the solder horn welding job.But, because traditional electric iron itself does not have lighting device, and electric iron is to use in the production of electronic products such as electronic equipment, electronic component, computer, household electrical appliance and maintenance, in the work because insufficient light, inefficiency and influence welding quality often, serious consequence even also can produce product off quality.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of electric iron that throws light on, and under the working environment of insufficient light, utilizes the lighting device of its configuration to solve lighting problem effectively.

For solving the problems of the technologies described above, the electric iron that throws light on of the present utility model, comprise solder horn, iron core, handle set, handle and power line, the outer face that handle set connects iron core is provided with the LED that shines facing to solder horn, its circuit connecting mode is: after each LED and the dropping resistor R parallel connection, with iron core R _LBe connected in series.Described LED is arranged on handle set end face semicircle one side.After electric iron is connected power supply, LED on the handle set end face is bright, and shine the solder horn head, because LED is arranged on handle set end face semicircle one side, can not produce shadow when LED shines on the solder horn, thereby reach the purpose of seeing pad clearly.

The beneficial effects of the utility model are, can utilize the lighting device of electric iron itself that illumination is provided in the working environment of insufficient light, and lighting device need not change the original contour structures of electric iron, and are simple in structure.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is further specified.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is circuit theory diagrams of the present utility model.

The specific embodiment

Referring to Fig. 1, Fig. 2, the electric iron that this can throw light on comprises solder horn 1, iron core 2, handle set 9, handle 7 and power line 8, and handle set 9 connects the uniform light emitting diode 3 (LED that are provided with 5 facing to solder horn 1 irradiation of outer face semicircle one side of iron core 2 ₁～LED ₅), its circuit connecting mode is: each light emitting diode 3 (LED ₁～LED ₅) parallel connection, negative pole connects an end of K switch, and positive pole is connected the negative pole tie point of the other end of K switch and battery E, the positive pole of commutation diode D with the positive pole of battery E, the negative pole of commutation diode D, be parallel to the two ends of dropping resistor R, dropping resistor R and iron core 2 (R _L) series connection.

Operation principle: dropping resistor R and iron core 2 (R _L) series connection, connect power supply after, electric current through dropping resistor R to iron core 2 (R _L), on R, produce AC voltage drop, after the voltage process diode D rectification,,, connect K switch to battery E charging from positive pole output pulsed dc voltage, electric current flows through light emitting diode 3 (LED by battery E ₁～LED ₅), K switch gets back to negative pole, light emitting diode 3 (LED ₁～LED ₅) luminous.When K switch disconnects, light emitting diode 3 (LED ₁～LED ₅) there are not an electric current, light emitting diode 3 (LED ₁～LED ₅) not luminous.When no alternating current is imported, connect K switch, light emitting diode 3 (LED ₁～LED ₅) luminous, can do emergency lighting.
