There are many nerve endings on the scalp, some nerve endings distance is very close to the brain, information on the scalp, which is easy to the brain. Fingers on the scalp massage, can stimulate scalp nerve endings, gently through the nerve reflex, make the thinking function of the cerebral cortex. When people meet with some surprisingly good, often with your fingers on the scalp to scratch scratch, make the train of thought is open, come up with a solution to the problem.
medical expert points out, excessive mental pressure is a common cause of hair loss. Mental tension, depression, fear, or serious can cause neurological disorders such as insomnia, capillary was contracting, hair follicles can not get enough blood supply, and scalp is located at the top of the human body, thus the hair fall off easily. Mental factors will seriously affect the growth cycle of the hair, long eye fatigue, mental pressure is overweight, too nervous, irritable, or fears, to stay up late, etc. , all can lead to hair growth cycle is shorten, appear hair loss phenomenon, lead to early bald.
there are a lot of brand market now scalp massager, to relieve the people nervous, relax the scalp, sweet and comfortable. But there is a problem worth to pay attention. This direct close contact with the scalp of electrical appliances with radiation? Is it safe? The brain but we can go to the vital organs, thinking, thinking is the part we will focus on the protection. So, the size of the scalp massager radiation, safe? Depends on its motor unit.
the permanent magnet has a brush motor, the motor is a mechanical structure of the brush and commutator to change the rotor current direction of the inner conductor, in the process of commutation which sparks, the spark is actually a kind of radiation. If often close to the brain, will also affect people's health. This traditional brush motor even in the beginning, when using the adoption of some of the pressure sensitive ceramics, capacitance, and inductance components to suppress this kind of radiation, such as let radiation within the scope of the standard, but after using for a period of time, it will spark, radiation and overweight. Another is the brushless motor, it has high reliability, long life, low power consumption, fast response, stable torque, constant speed, low radiation, low electromagnetic interference, the advantages of low noise and so on. This kind of motor does not produce sparks throughout the life cycle, its electromagnetic interference and electromagnetic radiation is very small.
as a result, the configuration of brushless motor safe and healthy scalp massager, recommended for people in need. Micro-motor controller brushless motor manufacturers of motor controller, as China's leading general standard brushless dc motor controller,无刷直流电机,刷)The r&d and manufacturing enterprises, professional research and development production of various kinds of small home appliance, personal care class dedicated brushless motor, worth customer trust!
