Description

Technical Field

[0001] The utility model relates to the technical field of laminar flow hood main body, in particular to a hidden installation structure of an air inlet plate of a laminar flow hood. Background Art

[0002] The laminar flow hood body is a commonly used clean equipment in the air purification industry. It can be flexibly installed above the process point that requires high cleanliness. It can highly clean the local environment, that is, it absorbs the air in the space, and sends it out through the filter at a certain wind speed by the fan and the damping layer forms a uniform flow layer by pressure balance, so that the clean air is delivered to the target area in a vertical laminar airflow, ensuring that a certain area reaches the required cleanliness. The laminar flow hood body can be used alone or combined into a strip-shaped clean area.

[0003] The air inlet holes on the existing laminar flow hood body are directly opened on the laminar flow hood body shell, which is inconvenient to clean the air inlet holes and affects the ventilation efficiency. Another method is to install an air inlet plate on the laminar flow hood body, and the air inlet plate is directly connected to the surface of the laminar flow hood body. However, this installation method will cause the air inlet plate to protrude from the surface of the laminar flow hood, which is easy to scratch and accumulate dust, and is not beautiful.
