However, this fan
While easy to use, it can be risky
Neck-mounted portable electric fan
Common security risks
Some products have design flaws
At present, the neck fans on the market are generally made of plastic, and some products have large gaps in the mesh fan cover, and in the process of rapid rotation of the fan blades, users are likely to be scratched by accidentally touching the fan blades. However, the product design of some neck-mounted electric fans is not reasonable, which can easily cause the hair to be caught in the rotating fan blades, thus damaging the scalp.
There is a risk of fire
The sales price of the neck-mounted portable electric fan is often between twenty or thirty yuan and nearly 100 yuan, and the reason for the price difference is mainly due to the inconsistent quality of the lithium battery used. If the product uses shoddy lithium battery parts, it may cause an explosion or fire.
It is easy to "accidentally injure" children
In terms of product appearance, many small fans with halternecks use cartoon images and colorful shells, which are easy to be used as toys by children. If you accidentally touch the switch, your child's fingers will touch the fan blades, and they are likely to get injured. It should be noted that the national mandatory standard clearly stipulates that "the shape and decoration of the shell of the appliance should not make the appliance easy for children to use as a toy".
Blowing a neck fan can cause facial paralysis
Zhang Zhi, director of the Department of Neurology of Hefei Second People's Hospital, once received a patient with facial paralysis due to blowing a neck fan. "The fan blows on the patient's cheeks, which is exactly where the facial nerve comes out of the skull, which is relatively weak, if the fan blows and the air conditioner blows directly at the part, it is easy to be invaded by the virus, causing common facial paralysis, also known as facial neuritis."
"Patients with facial paralysis are prone to symptoms such as crooked corners of the mouth and weak eyelid closure." Zhang Zhi said that in addition to causing the above symptoms, hanging a fan or ice ring directly on the neck will also cause the physiological curvature of the cervical spine to straighten, which will have a certain impact on the cervical spine and the nerves and blood vessels of the neck. "The most common ones are neck and shoulder pain, cervical spondylosis, and in severe cases, it can also cause blood vessels in the neck to constrict and reduce blood flow, leading to the occurrence of cerebrovascular disease."
