Abstract

The utility model provides a combined electric iron and an electric iron head which mainly adopt the technical scheme as follows: a ring sleeve is inwards formed at the periphery of the hot contact plane of the electric iron head and is sleeved on the front end part of a heat conducting core of the electric iron so as to ensure that the hot contact plane of the electric iron head and the contact plane at the front end part of the heat conducting core are positioned in the ring sleeve, thereby molten soldering tin of the electric iron head is prevented from counterflow to stain the heat conducting end surface of the heat conducting core. The combined electric iron is used for a long time, the heating speed of the electric iron is not lowered due to being stained by the soldering tin, and the service life of the combined electric iron is effectively prolonged.

Description

Combined electrical flatiron device and electric soldering bit thereof

Technical field

The utility model refers to a kind of structural improvement that is applied to combined electrical flatiron device especially about a kind of electric iron device.

Background technology

See also Fig. 4 and shown in Figure 5, be the exploded view of existing combined electrical flatiron device 50, it includes:

One grip 51, its end have passed a power line 52, for being inserted in the supply socket;

One heat conduction core 53, its terminal front end that is provided with and is fixed in this grip 51, this heat conduction core 53 mainly with silver as Heat Conduction Material, for accelerating heat-transfer rate, the front end of this heat conduction core forms a plane, as main heat conduction end face 531 again;

One combined pipe fitting 54, its end are screwed together on the heat conduction core 53, and so that heat conduction core 53 is sheathed on wherein, its front end then is formed with a perforation 541 again; And

One electric soldering bit 55 penetrates from combined pipe fitting 54, and its front end passes from this combined pipe fitting 54 front ends perforation 541, and its end forms a thermo-contact plane 551 again, to contact with the heat conduction end face 531 of heat conduction core 53.

Please cooperate consult shown in Figure 6, combinations thereof formula electric iron device 50 is after electric soldering bit 55 is arranged at combined pipe fitting 54, to be screwed together on the heat conduction core 53 again, makes heat conduction core 53 contact with electric soldering bit 55, heat guiding structure to this electric soldering bit 55, raises its temperature and carries out the scolding tin operation.Owing to use electric soldering bit 55 meeting oxidations for a long time or can't quickly heat up to high temperature because of being infected with too much gasification tin, change and must eliminate, this moment, the user was as long as open combined pipe fitting 54 to last spiral shell from heat conduction core 53, take out electric soldering bit 55, replace new electric soldering bit 55 according to above-mentioned installation steps again and can reuse; Yet, though combined electrical flatiron device 50 provides the structure of changing electric soldering bit 55, can reduce number of times and the cost of changing electric iron device 50, but combinations thereof formula electric iron device still has shortcoming.

That is, because electric soldering bit is to see through combined pipe fitting and heat conduction core thermal contact conductance, electric soldering bit and the combined pipe fitting last sealing and fixing of boring a hole again, when therefore carrying out the scolding tin operation, liquid tin can because operation action and adverse current to heat conduction core, particularly the heat conduction end of heat conduction core forms tin oxide on the heat conduction end face of this heat conduction core of getting off for a long time, lowers this heat conduction core with the speed of heat guiding structure to electric soldering bit; So, use for a long time, find that also the firing rate of electric iron device is slack-off even if more renew electric soldering bit, even do not reach the scolding tin processing temperature, so must purchase the electric iron device again.

The utility model content

Because above-mentioned shortcoming, the utility model is mainly created purpose and is to provide a kind of combined electrical flatiron device and electric soldering bit thereof that increases the service life that have.

Desire to reach above-mentioned purpose, the employed major technique means of the utility model provide a kind of electric soldering bit of combined electrical flatiron device, form a tip in the body front end, and body tip forms a thermo-contact plane, periphery in this thermo-contact plane inwardly forms a ring set again, for the leading section of the heat conduction core that is sheathed on the electric iron device.

The utility model also provides a kind of combined electrical flatiron device, includes: a grip, and its end has passed a power line, for being inserted in the supply socket; One heat conduction core, its terminal front end that is provided with and is fixed in this grip, this heat conduction core front end is the heat conduction end face again; One combined pipe fitting, its end are bonded on this heat conduction core, and so that heat conduction core is sheathed on wherein, its front end then is formed with a perforation again; An and electric soldering bit, form a tip in the body front end, and body tip forms a thermo-contact plane, the periphery in this thermo-contact plane inwardly forms a ring set again, being sheathed on above-mentioned heat conduction core leading section, and make the thermo-contact plane contact with the heat conduction end face of heat conduction core front end.

Because of this thermo-contact plane and heat conduction end face promptly are positioned at ring set inside, avoiding on the electric soldering bit liquid tin adverse current fully and to be infected with on the heat conduction end face of heat conduction core front end, and keep the firing rate of electric iron device, the service life of effectively improving combined electrical flatiron device.

Electric iron device of the present utility model then is that above-mentioned electric soldering bit is arranged at earlier in the combined pipe fitting, is bonded on the heat conduction core again, and the heat conduction core that order is connected with grip is subjected to heat and conducts to electric soldering bit, carries out the scolding tin operation.
