Abstract

The utility model provides a self smoke exhaust internal set air-flue type electric soldering iron, comprising an electric soldering head, external heating type electric heating tubes, a plastic handle and a power cord. Metal exhaust tubes are arranged outside the external heating type electric heating tubes. An air-flue communicated with the hollow cavity of the plastic handle is provided between the metal exhaust tubes and the external heating type electric heating tubes. A smoke exhaust port, inside which a ventilating fan is provided, is arranged at the tail part of the hollow cavity of the plastic handle. The utility model has the advantages that basing on one normal electric soldering iron, one controllable exhaustion pumping system is added to suck the smoke of the soldering process into the inner cavity of the electric soldering iron, exhausting from the tail part of the electric soldering iron without hurting the eyes.

Description

From the built-in air duct type electric iron of smoke evacuation

Technical field

The utility model relates to a kind of built-in air duct type electric iron of discharging fume certainly, belongs to the scolding tin instrument, the scolding tin instrument that specifically a kind of cigarette that is used for the generation of electric iron course of work solder stick can discharge.

Background technology

Advantages such as electric iron commonly used is easy to use because of it, heat conduction is fast are very popular, but iron the sootiness eye because electric iron uses solder stick to produce in the course of the work, perplexing people always.Up to now, still finding no a kind of easy method can address this problem.

Summary of the invention

The purpose of this utility model provides the built-in air duct type electric iron of a kind of smoke evacuation certainly simple in structure, easy to use, swift to operate.

The utility model is realized like this: the built-in air duct type electric iron of discharging fume certainly comprises electric soldering bit, external-heat electrothermal tube, plastic handle, power line, it is characterized in that: the outside of external-heat electrothermal tube is the metal exhaust duct, between metal exhaust duct and the external-heat electrothermal tube is the air channel, the air channel communicates with the plastic handle cavity, plastic handle cavity afterbody is an exhaust opening, and ventilating fan is housed in the exhaust opening.

Advantage of the present utility model: this novel electric iron is to increase a controlled pump drainage wind system cigarette in the welding process is sucked the electric iron inner chamber on the basis of a normal electric iron, is discharged by the afterbody of electric iron again, can not hurt eyes.

Description of drawings

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

Fig. 2 is a circuit diagram of the present utility model.

Among the figure: 1, electric soldering bit; 2, external-heat electrothermal tube; 3, the sleeve pipe that has air vent; 4, metal exhaust duct; 4-1, air channel; 5, switch; 6, power line; 6-1, internal and external line joint; 7, direct current ventilating fan; 8, plastic handle; 8-1, plastic handle cavity; 8-2, afterbody exhaust opening; 9, air inlet; 10, alterating and direct current converter.

The specific embodiment

As Fig. 1: the built-in air duct type electric iron of discharging fume certainly comprises electric soldering bit 1, external-heat electrothermal tube 2, plastic handle 8, power line 6, the rear portion of external-heat electrothermal tube is the sleeve pipe that has air vent, the external-heat electrothermal tube is a metal exhaust duct 4 outward with the sleeve pipe 3 that has air vent, between metal exhaust duct front portion and the electric soldering bit 1 air inlet 9 is arranged, be air channel 4-1 between metal exhaust duct and the external-heat electrothermal tube, the air channel communicates with plastic handle cavity 8-1 by the hole on the sleeve pipe that has air vent, plastic handle cavity afterbody is exhaust opening 8-2, ventilating fan 7 is housed in the exhaust opening, and power line 6 is connected with interior lines by internal and external line joint 6-1, and the 5th, row's envelope fan switch.

Fig. 2 is a circuit diagram of the present utility model: when power line 6 is given 2 power supplies of external-heat electrothermal tube, give the alterating and direct current converter 10 power supplies, alterating and direct current converter 10 is converted to direct current for ventilating fan 7 with alternating current, switch 5 is arranged in the DC circuit, being convenient to control direct current ventilating fan 7 rotates, outwards exhausting smoke evacuation, the black smoke that is produced during welding will enter from air inlet 9, manage interior air channel 4-1 to the sleeve pipe 3 that has air vent by the metal air draft, enter plastic handle cavity 8-1, discharge from plastic handle afterbody exhaust opening 8-2.

Claims

1. one kind from the built-in air duct type electric iron of discharging fume, comprise electric soldering bit, external-heat electrothermal tube, plastic handle, power line, it is characterized in that: the outside of external-heat electrothermal tube is the metal exhaust duct, between metal exhaust duct and the external-heat electrothermal tube is the air channel, between metal exhaust duct front portion and the electric soldering bit air inlet is arranged, the air channel communicates with the plastic handle cavity, and plastic handle cavity afterbody is an exhaust opening, and ventilating fan is housed in the exhaust opening.
