Is there a problem with the electric spark in the newly bought electric hair dryer? I don t dare to

The most authoritative!! It's my own experience, and it's something I've dealt with myself.

I recently bought a new hair dryer, I didn't pay attention to it when I tried it, and when I got home, I found that when I turned on the hot air, there were small sparks in it, which was suspected to be a quality problem. Later, I always felt unsafe, so I checked my old hair dryer and it didn't have this problem. Through careful observation and comparison, it was found that the old hair dryer and the newly bought hair dryer were different from the angle of the iron sheet connected between the internal power cord and the resistance wire as far as the naked eye could see from the air outlet.

The old hair dryer iron sheet is about 70 degrees beveled, and the new hair dryer iron sheet is 0 degree angle. So I ruthlessly dismantled the new hair dryer I had just bought, twisted the iron piece to 70-90 degrees with tongs, and then restored the hair dryer. Try again, turn on the hot wind and blow hard for a while, but I didn't find any sparks, and the problem was solved!

It's been three months, and I haven't had any more problems with Mars! Later, through my own analysis, it was an iron sheet with a 0-degree angle, and when the hot air came out in the middle of the hair dryer, there was a certain resistance, which caused the iron sheet to heat up, redden, and spark again, and the wind resistance was reduced by changing the angle of the iron sheet. I don't think it has much to do with the brushes, the new machine is just in the design structure, and the manufacturer does not consider it, so it causes confusion for us ordinary consumers.

I also bought a new electric hair dryer last night, I didn't try it when I bought it, and when I went home and tried to open it, I basically had it every time I turned it on, and I wanted to change it, but the boss said "it's okay, I'm not afraid", and I got it back

No, it's from the motor, the motor is a DC motor, there are brushes, and there will be sparks when the brushes are not in good contact with the transposition, which is normal!

When the brush motor is working, there will be a proper electric spark, as long as the sound is uniform when working, the air outlet is normal and there is no peculiar smell, it is safe.

It's okay, there are any, some power tools are produced by AC excitation motors, brushes commutation.

It's easy to get electrocuted, so don't worry about it.

Of course it works. There will be no electric shock, and the electric spark is generated by the temperature limit switch inside. It may be that the air outlet is too close to the air outlet and the air volume is insufficient, resulting in too high temperature. The temperature limiting switch protects against electrical sparks. There are no adverse effects, so you can use it with confidence.

Generally, the spark of the carbon brush of the motor of the hair dryer is matched, if it is not very large, it is normal to see a small continuous spark. If you see a continuous and large spark and a discharge sound, it needs to be repaired.

Related Notes:

1) The hair dryer must be used under the power supply voltage specified on the nameplate. For hair dryers with three-wire power cords, the grounding wires should be properly connected.

2) When using the hair dryer to collapse the finger, its air inlet and outlet must be unobstructed, otherwise it will not only fail to achieve the use effect, but also cause overheating and burn out the appliance.

3) When used to dry wet hair, the air outlet of the hair dryer should be kept at a certain distance (not less than 50mm) from the hair to prevent the air outlet from being blocked and scorched hair. At the same time, it is important to keep a certain distance to avoid water vapor generated when drying hair that affects the dielectric strength and cause leakage.

4) Before the end of use, try to switch the hair dryer from the "hot" to the "cold" mode first, so as to cut off the power supply of the electric heating element first. Then let the remaining heat of the electric heating element be blown out by the cold air, so that the internal temperature of the electric hair dryer will be reduced, and then all the power will be cut off. This slows down the aging of the internal insulation of the hair dryer and prolongs the service life.

At the same time, it is not easy to burn other objects when placed on the table.

If there is a spark inside the hair dryer, this is a serious safety issue and it is recommended to stop using the hair dryer. Sparks can be caused by short circuits in electrical wiring, motor failures, or other electrical problems that can lead to a risk of electrical or electrical strikes.

For safety reasons, it is not recommended to continue using a hair dryer with sparks. Here are some suggestions to deal with this situation: Sikai.

1.Disuse: Immediately stop using the hair dryer, disconnect it from power and unplug it. Do not continue to use it to avoid causing more serious safety incidents.

2.Check the appliances: Check the wires and plugs of the hair dryer for damage to see if there are visible shorts or broken circuits. If you notice significant damage to your appliances, you should avoid using them and seek advice to repair or replace your hair dryer.

3.Seek professional help: It is recommended that you take your hair dryer to a professional appliance repair center or contact the manufacturer for service. They have the experience and expertise to inspect and fix problems with hair dryers to ensure safe use.

4.Precautions: When using the hair dryer in the future, remember the following safety measures: Make sure the plug is securely inserted into the outlet. Avoid placing the hair dryer in a wet or flammable place. Clean filters and vents regularly to prevent clogging and overheating.

Keeping your home safe and healthy is crucial, especially when it comes to electrical appliances. For sparkling hair dryers, to be on the safe side, discontinue use and seek professional repair advice. <>

Of course it works. There will be no electric shock, and the electric spark is generated by the temperature limit switch inside.

Is there an electric spark when using it? Or just plug it in? Poor contact, I studied electronics, according to experience, it will not affect the work of the hair dryer, but it is better to change the switch!!

It's simple. Otherwise, if you use it like this for a long time, you may burn out the plastic. If you're asking if you're electrocuted, I don't think so.

It may be that the surface of the switch contact electrode piece is oxidized or closed tightly, resulting in poor contact sparks, because the hair dryer uses a voltage of 220V, it is recommended not to use it again, and if you want to use it, you must also replace the switch If you want to use it, there is no spark when the switch is not sparked.

That's because the switch is in bad contact, it has nothing to do with leakage, you can make do with it, and then change it when the switch is broken, and now many cheap light switches are ignited.

It is a poor contact, and it can be used temporarily, but it will not be too long, and it should be repaired as soon as possible.
