If you hear a fire, it depends on whether it burns and then goes out, or it doesn't move at all. If it is the former, it means that the solenoid valve is opened for a period of time and then closed again. Typically, you will hear about integration Intelligent thermostatic water heater There is a "beep" at the opening of the solenoid valve. If it is the latter, the solenoid valve usually does not open at all, and most lighters are broken, so only one can be replaced. The solenoid valve is usually not damaged, that is, the damage rate is low. However, because the low-quality integrated intelligent thermostatic water heater uses low-quality materials to make the solenoid valve rod, it is easy to rust, resulting in poor movement of the rod, which makes the solenoid valve unable to open. However, you can remove the rust and place the motorcycle oil, and the sliding and taxiing can return to normal.

If it burns and goes out, it means that the lighter can work normally immediately. This phenomenon is related to the energy-saving design of lighters. Those who have studied electrical engineering will know that when the electromagnet starts, it needs more current, and after starting, it only needs less maintenance current. There are two currents when the solenoid valve is opened, and the solenoid valve also has two working coils. At the beginning, there is usually current flowing from both circuits, so the solenoid valve can be opened smoothly. After opening, no such large current is required, so the circuit called starting circuit is closed. The starting current is usually large, and the solenoid valve can be started separately.

Speaking of this, everyone should understand that it is a problem to keep the current off after combustion. If the maintenance circuit is abnormal, the battery voltage is too low or the lighter is faulty, please replace it. This kind of failure often occurs in some integrated intelligent thermostatic water heaters on the market. If you have the ability to repair electrical appliances, you can also repair lighters yourself.

If the normal combustion occurs after contacting boiling water, and the ignition indicator is on, but the ignition continues, the ignition will stop and the combustion will stop at the same time after about ten seconds. Generally, there are problems with the combustion detection circuit of the lighter, and most of the problems are caused by poor contact between the probe and the wire. In order to prevent gas from entering the burner without burning and overflowing, in addition to the two ignition pins, there is a combustion detection probe beside the burner. The probe is not made of any special material, but is connected to the burner with a flame, which destroys the oscillation state of the high-voltage oscillator inside the lighter and stops ignition when it catches fire, saving energy and reducing combustion efficiency. Always output maintenance current to keep the solenoid open. If there is no fire, the internal oscillator will time out, stop ignition, and then close the solenoid valve.
