(3) Beneficial effects

Compared with the prior art, the beneficial effects of the present invention are:

1. The fully enclosed one-way circulation ventilation protective clothing works by setting a flat air inlet, an air intake hose, an automatic exhaust valve, a silent exhaust pump, a silent oxygen-enriched air supply pump, and a silent oxygen-enriched air supply pump. The outside air is allowed to enter the protective suit, and the anti-virus filter cover is set up to effectively filter the gas, and only through the air intake and exhaust to the outside world, the silent exhaust pump and the automatic exhaust valve make the gas only flow outward. "One-way channel", and through the cooperation between the anti-virus filter and the anti-virus filter cover, it can effectively supply oxygen while preventing the virus from entering the inside of the protective clothing, effectively solving the problem of hypoxia and hypoxia caused by medical staff wearing protective clothing. It is beneficial to the normal work of medical staff and is very applicable.

2. The fully enclosed one-way ventilation type protective clothing is equipped with an anti-virus filter cover, an anti-virus filter, a silent oxygen-enriched air supply pump, a silent exhaust pump and a transparent mask, and the silent oxygen-enriched air supply pump is used for automatic air supply and breathing. It is more enjoyable and subverts the situation of N95 mask suffocation and difficulty breathing. The internal pressure of high protective clothing is higher than the external pressure, so that the underwear is not close to the body, the clothing is not wet, and the wearing is loose and comfortable. Material, while effectively blocking the virus, the medical staff does not have to sit up and breathe after wearing it, and the conversation voice is clear and the sound insulation of the hearing is small. The protective clothing is comfortable to wear, loose and free from binding, and can be retorted, cleaned and disinfected at high temperature for repeated use, further improving the medical staff. Wearing comfort and its cost of use.

3. The fully enclosed one-way ventilation type protective clothing is equipped with a transparent mask, an air intake hose, an adjustable bracket and a sealing zipper. Wetting the mask due to factors such as exhalation, sweating, coughing, sneezing, snot, etc. causes moisture to be exchanged inside and outside the respiratory airflow to bring the virus into the mouth and nose, and the risk of invading the nose and mouth avoids the risk of virus-stained mask cloth sticking to the nose and mouth. The risk of intrusion is easy. The adjustable bracket makes it easy for medical staff to adjust the distance between the transparent mask and the human face to improve wearing comfort. At the same time, it flows through the eyes and nose for breathing, which can effectively prevent the fogging phenomenon of glasses and transparent masks. Because of the sealing zipper, it is convenient for medical staff to wear while enhancing the sealing and anti-virus.
