The main innovations of the fully automatic electric soldering iron: 1. Automatic power off, touch wake-up When the user stops using the electric soldering iron for a period of time (users can set it by themselves), it will automatically power off and stop heating. After the automatic power-off, the user stops using the soldering iron for any time, as long as the power is not turned off, when the soldering iron is used again naturally, the soldering iron is automatically awakened and resumes normal work. 2. Automatic temperature adjustment by touch When users use the electric soldering iron, they can touch the handle as usual to select the four-speed temperature control temperature and automatically adjust the temperature, eliminating the vulnerable artificial mechanical temperature adjustment parts widely used in current electric soldering irons. 3. Take it out of the box and improve work efficiency Whether it is the initial use every day or the soldering iron is used again after a period of suspension, when the user uses the soldering iron, it will automatically fuzzily infer the stop time and the current temperature of the soldering iron, and based on this Determine the time required for rapid heating, and then immediately start the flash heating program to heat the soldering iron to the normal operating temperature. Compared with the electric soldering irons currently on the market, the waiting time for the user is extremely short, and the user can basically use the electric soldering iron after picking it up, which greatly improves the work efficiency. 4. Humanized step-by-step cooling, safety and energy saving When people use electric soldering irons, they sometimes stop using them. If it works normally, the pause time is generally short, and the user hopes to keep the soldering iron at a constant temperature during the normal pause period, so that instant welding is convenient to use, and as the pause time prolongs, the probability of the user using the soldering iron again gradually decreases, or even Will not be used for a long time. The touch control system simulates the above-mentioned process of people using the electric soldering iron. If the time of suspending the use of the electric soldering iron (set by the user) is short, the touch control system controls the heating device to keep the temperature of the electric soldering iron constant. After a period of delay, if the user still does not Touch and use the electric soldering iron, it will automatically start the step-by-step cooling program, and the cooling degree is proportional to the time when the electric soldering iron is stopped, until the power is turned off and the heating is stopped. The greater the probability that the user will use the soldering iron again, the higher the temperature maintained by the soldering iron will be, and the shorter the time for rapid heating of the soldering iron when touching it again, is convenient for immediate use of the soldering iron. As the probability of the user using the electric soldering iron again gradually decreases, the temperature of the electric soldering iron is gradually lowered, which is beneficial to saving electric energy. After the electric soldering iron is stopped for a long time, the power is automatically cut off, which not only saves electric energy, but also prevents burning of surrounding appliances and even fires due to forgetting to turn off the power supply of the electric soldering iron, thereby improving safety. In addition, it can avoid shortening the service life of the soldering iron head (vulnerable parts) due to long-term high-temperature dry burning. 5. Originally created touch sensing circuit, making special touch key for electric soldering iron Innovatively designed touch sensing circuit for electric soldering iron, selected electronic components, determined relevant parameters through experiments, made anti-interference PCB, and developed special touch key for electric soldering iron. 6. One key is divided into three keys to improve the anti-interference ability. The three touch keys of the electric soldering iron are combined into one touch key to complete a function together, that is, one key is divided into three keys, which can be realized with only one touch key. Change the function of the three touch keys to realize this function together. Since one touch key is easily disturbed, the probability of three touch keys arranged alternately being disturbed at the same time is very low, thereby effectively improving the anti-interference ability of the touch keys. Compared with the electric soldering irons currently on the market, the fully automatic electric soldering iron has the following highlights: touch temperature adjustment; intelligent temperature control; rapid temperature rise; automatic power off; touch sleep wakeup; automatic judgment of fast heating time; comfortable. The fully automatic electric soldering iron can meet the requirements of picking up and using immediately, that is, putting it down and turning off the power, and maintaining a suitable constant temperature state.
