Description

Technical Field

[0001] The utility model relates to the technical field of electric soldering irons, in particular to an electric soldering iron with a temperature display. Background Art

[0002] There are thermostatic soldering irons on the market that can adjust the power output of the soldering iron, that is, adjust the working temperature of the soldering iron to suit different welding materials. However, the current thermostatic soldering irons have a thermostatic knob on the thermostatic power supply. Since there is no temperature display on the thermostatic power supply, the thermostatic knob can only roughly adjust the temperature of the soldering iron, and the user does not know the specific working temperature of the current soldering iron. On the other hand, even after the power is turned off, it still takes a certain amount of time for the soldering iron to cool down, and burns are often encountered by accidental touch.

[0003] After searching the Chinese patent with publication number CN205057236U, an electric soldering iron with temperature display is disclosed. When the thermostatic power supply is turned on and the temperature knob is adjusted, the soldering iron gun starts to heat up. When the temperature display data is stable, it is the current temperature of the soldering iron gun. The user can continue to adjust the temperature knob as needed so that the final displayed temperature of the soldering iron gun is the temperature required by the user; even if the thermostatic power supply is turned off, the temperature sensor and the display screen are still working, and the user can still see the current temperature change of the soldering iron gun, prompting the user to be careful of burns. The electric soldering iron can directly display the temperature of the soldering iron gun, which is convenient and intuitive.

[0004] Based on the above search and combined with the prior art, it is found that the above patent has certain defects. The temperature is displayed only by numbers on the display screen, and the understanding method is still not intuitive enough. Workers may ignore it. It is also possible that the numbers on the display screen cannot be seen at the first time due to the placement direction of the soldering iron, and burns are still likely to occur, which reduces the efficiency of the use of the soldering iron.
