The sound insulation earplug is generally made of silica gel or low-pressure foam mould material and high-elasticity polyester material, and is a daily article which is safe to human bodies and beneficial to physical and psychological health. After being inserted into the auditory canal, the ear canal is closely contacted with the external auditory canal so as to isolate sound from entering the middle ear and the inner ear (eardrum), thereby achieving the purpose of sound insulation and protecting the hearing of workers. The existing common sound-insulation noise-control earplug is a solid body, so that the inside of an ear is isolated from the outside air, negative ion components in the air cannot be absorbed in the ear, pressure and pain in the ear can be felt after continuous long-time use, and nausea can be caused in severe cases.
It is well known that the main functions of negative ions are: the negative ions have effects of tranquilizing, relieving pain, relieving cough, relieving itching, promoting urination, stimulating appetite, and lowering blood pressure. For example, after thunderstorm, the negative ions in the air are increased, and people feel happy. For example, in an air-conditioned room, negative ions in the air almost completely disappear after being subjected to a series of air-conditioning purification treatments and a long ventilating duct, people feel oppression in chest, dizziness, fatigue, and decline in working efficiency and health condition after staying in the room for a long time, and the negative ions with small particle size have good biological activity and are easy to permeate through the blood brain barrier of a human body to enter the human body to exert the biological effect of the negative ions.
