Problems solved by technology
However, in daily maintenance work, the electric soldering iron is often in a long-term energized working state. Due to overheating, the tip of the soldering iron is seriously oxidized, resulting in no tinning on the tip of the soldering iron, which seriously affects normal use.
The Chinese patent publication number is CN1069919A, and the patented technology titled "internal heating type high and low temperature electric soldering iron" provides a high and low temperature electric soldering iron, which is characterized in that the temperature of the electric soldering iron can be adjusted, but its temperature adjustment is only a single high, There are two grades of low temperature, and the temperature of the electric soldering iron cannot be controlled steplessly; the Chinese patent publication CN201279645Y, the invention patent named "a kind of internal heating electric soldering iron", provides an electric soldering iron with high thermal efficiency and energy saving , its shortcoming is that no corresponding solution to the shortcoming of the electric soldering iron is easy to oxidize, thus failing to fundamentally solve the shortcoming of the short life of the electric soldering iron

Embodiment Construction
[0012] exist figure 1 Use Φ1.45~Φ1.5mm iron wire to wind 30~35 turns on the periphery of the soldering iron core. The dotted line indicates the first wire end, which is pressed under the whole coil. After the iron wire coil 1 is wound, it is twisted with the second wire end. Tighten it, leaving a 1.5-2cm long stranded wire, and then divide the two wire ends horizontally to form two "feet 4" with a total length of 2-2.5cm, which are used to support the electric soldering iron. After this treatment, the temperature of the whole electric soldering iron is lowered, and at the same time, it effectively prevents the soldering iron tip from being oxidized at high temperature.
[0013] exist figure 1 In order to further reduce the peripheral temperature of the soldering iron core and prevent oxidation of the soldering iron core and iron wire, Φ2~Φ2.5mm aluminum wire is wound around the periphery of the wire circle, and the number of winding turns is 10~15 turns.

The invention discloses a temperature adjustable internal heating electric soldering iron, consisting of a soldering iron head (5), a connecting rod (6), a handle (7), a soldering iron core (2) and an electronic voltage regulator (3). Rings of iron wires (1) and aluminum wires for reducing temperature and preventing oxidation are winded in the periphery of the soldering iron core (2). The electronic voltage regulator (3) consists of a voltmeter (8), a voltage adjusting knob (9) and a power supply switch (10) for adjusting the voltage so as to adjust the temperature of the electric soldering iron.
Description
technical field [0001] The invention belongs to an internal heating type electric soldering iron. In particular, it relates to a novel internal heating electric soldering iron with adjustable temperature and energy saving. Background technique [0002] For home appliance maintenance personnel, electric soldering iron is one of the necessary welding tools in maintenance work, and its quality directly affects the efficiency of maintenance work. However, in daily maintenance work, the electric soldering iron is often in a long-term energized working state. Due to overheating, the tip of the soldering iron is severely oxidized, resulting in no tinning on the tip of the soldering iron, which seriously affects normal use. The Chinese patent publication number is CN1069919A, and the patented technology titled "internal heating type high and low temperature electric soldering iron" provides a high and low temperature electric soldering iron, which is characterized in that the tempe...
