Under What Circumstances Does A Hair Dryer Explode?

Hair dryers may explode in the following situations:
1.The air outlet of the hair dryer is covered, affecting heat dissipation, which may lead to overheating and combustion. 
2.Hair dryers placed on flammable items, especially high temperature blowers that have just been used, may ignite surrounding combustibles.
Hair dryer aging or short circuit, such as abnormal noise, odor, smoke, etc., which may be due to the degradation of internal parts or circuit problems. 
3.Continuous use of hair dryers for a long time makes it difficult to maintain a safe heat balance, which may lead to overheating and fire. 
4.The wire insulation of the hair dryer is broken, causing the wire to be exposed and short-circuited. 
5.When using a hair dryer in a humid environment, moisture entering the interior may cause damage to parts.
6.Using inferior hair dryers, poor quality may lead to safety problems.
7.Poor wiring, such as loose plug or poor contact, resulting in unstable current. 
Poor socket contact may cause overheating and aging of internal wiring.
