The utility model content

The purpose of this utility model is to overcome the common disadvantage of existing electric iron, provide a kind of small and exquisite, easy to use, need not use that transformer, heating are fast, the electric iron of DC power supply.

For achieving the above object, the utility model has been taked following technical scheme:

The fast thermoelectric flatiron of a kind of direct current comprises power supply, flatiron handle, heater element and solder horn, and described heater element is made up of heating element and thermal insulation layer, and described heating element comprises the heating wire and first asbestos pipe, and described heating wire is close on first asbestos pipe; Described thermal insulation layer is made up of second asbestos pipe, and described second asbestos pipe is set in outside the heating element; Described heating wire is communicated with by enamel-covered wire with path between the power supply.

Solder horn is set in outside the thermal insulation layer, is a kind of inner heating type electric iron.

Solder horn is arranged in the asbestos pipe of heating element, is a kind of external-heat electric iron.

Be the energising and the outage of convenient control electric iron, described electric iron flatiron handle is provided with switch.

Compared with prior art, the utlity model has following beneficial effect:

1. the utility model need not to use transformer, and preheating time is fast, can save electric energy significantly, shortens preheating time, reduces heat loss, improves the service life of steel toe and heating element heater;

2. use low pressure, dc source or storage battery power supply, overcome the common electrical flatiron and can only use the shortcoming of AC power, and not influenced by power failure;

3. use and press the of bonding switch, make things convenient for the energising and the outage of electric iron;

4. build is small and exquisite, and is easy to carry and use.

Description of drawings

Come the utility model is done to set forth further below in conjunction with the drawings and specific embodiments.

Fig. 1 is the structural representation of the utility model embodiment 1 inner heating type electric iron;

Fig. 2 is the structural representation of the utility model embodiment 2 external-heat electric iron;

Reference numeral: 1, power supply; 2, flatiron handle; 3, heater element; 4, solder horn; 5, heating element; 6, heating wire; 71, first asbestos pipe; 72, second asbestos pipe; 73, the 3rd asbestos pipe; 8, enamel-covered wire; 9, switch.

The specific embodiment

Below describe the utility model in detail by specific embodiment.

The utility model has utilized that asbestos pipe is high temperature resistant, thin thickness, characteristics that heat transfer is fast, makes efficient higher than traditional electrical flatiron, has shortened preheating time greatly.

Embodiment 1:

See also Fig. 1, the fast thermoelectric flatiron of a kind of internal heat type direct current comprises power supply 1, flatiron handle 2, heater element 3 and solder horn 4, and described heater element 3 is made up of heating element 5 and thermal insulation layer, described heating element 5 comprises the heating wire 6 and first asbestos pipe 71, and described heating wire 6 is close on first asbestos pipe 71; Described thermal insulation layer is made up of second asbestos pipe 72, and described second asbestos pipe 72 is set in outside the heating element 5; Described heating wire 6 is communicated with by enamel-covered wire 8 with path between the power supply 1.

In this embodiment, described solder horn 4 is arranged on outside the thermal insulation layer, constitutes inner heating type electric iron.

Heating wire is close to constitute heating element on first asbestos pipe, be because can shorten the physical dimension of solder horn and heater element so greatly, again because heater element is to be embedded in the solder horn the inside, can make the working end (molten tin part) of heater element like this near solder horn, heat is concentrated, and can heat up rapidly.

Be energising and the outage that makes things convenient for electric iron, the utility model flatiron handle 2 is provided with switch 9.
