Description

Technical Field

[0001] This utility model relates to the field of air showers, specifically to a circulating air shower. Background Technology

[0002] Air showers are essential equipment for cleanrooms and are commonly used in the manufacturing of electronic products, pharmaceuticals, LCD displays, and precision instruments. Air showers are installed in front of cleanrooms. Before entering a cleanroom, workers need to pass through the air shower to remove dust from their surfaces, which greatly reduces the risk of dust being brought into the cleanroom and ensures the cleanliness requirements of the cleanroom.

[0003] The "air shower" disclosed in application number "CN203437371 U" effectively solves the technical drawbacks of air showers, such as the presence of many floating particles that affect the cleanliness and cleaning effect of the air shower itself, through specific technical structural settings. However, in actual use, similar circulating air showers still have many defects. For example, when cleaning dust adhering to personnel, the existing air showers blow clean in a fixed direction, which is not convenient for forming a circulating cleaning operation. This makes it difficult for some areas to be air showered, resulting in a mediocre air shower effect. Furthermore, it cannot remove dust from the bottom of workers' shoes, making the air shower incomplete and the cleaning efficiency low, leaving room for improvement. Utility Model Content
