Because the biggest generating source of bacteria and dust is the staff under the dynamic condition, whether the action of drenching with the wind is normal when entering seriously influences the effect of drenching with the wind.
At present, the following unsolved items exist in the traditional air shower: firstly, the wind showering effect of the traditional wind showering room is limited by the current behavior of a wind showering person, if the wind showering person leans against a wind showering opening or the arms are not lifted, the wind showering is not thorough, wind showering blind areas such as leaning sides, arms and inner sides of the arms exist, and a certain amount of dust with larger particle sizes is attached. And secondly, in a multi-person wind shower, particularly when more than 3 persons wind at the same time, the persons standing on two sides are only showered by wind on one side, the other side is not showered by wind, and the persons standing in the middle of the crowd are almost not showered by wind because the blowing openings are blocked by the persons on two sides. A large amount of dust adheres to the clothes of those persons and is carried into the clean room. And thirdly, when the person is on duty, the person is fussy, so that potential safety hazards are easily caused, sitting type wind showering is beneficial to stabilizing emotion, and the worker can have a rest temporarily. Fourthly, the large air shower occupies a large area and has high energy consumption, and the common small air shower can achieve good air shower effect only in a long time.
