The right port of the fan-shaped guide cavity is connected to the arc-shaped chamber, which is arranged in the right end wall of the clean room. A plurality of inclined guide cavity holes are opened on the left inner wall of the arc-shaped chamber. The inclined guide cavity holes can lead the gas in the arc-shaped chamber upward, thereby increasing the difficulty of reflux of high-density gases such as carbon dioxide. A filter frame is arranged in the middle of the clean room.

[0006] Preferably: the circulation system comprises an intake fan, a conical air duct, a connecting air duct, a guide slide and a lower mesh plate, and a plurality of intake fans are installed on the left side and the upper part of the front and rear walls inside the clean room, and the same conical air duct is arranged at the rear end of the intake fan on the same wall surface.

[0008] Preferably: a plurality of lower mesh plates are installed at the lower end port of the connecting air duct, and the surrounding sides of the lower mesh plates are sealed to prevent air flow from escaping. Impurities carried by the intake air flow are guided to the vicinity of the lower mesh plates through a guide slide for discharge, thereby reducing blockage in the connecting air duct.

[0009] Preferably, the filter frame divides the inner chamber of the clean room into two chambers, the left chamber is used for actual use, and the right chamber is used as an inner circulation gas processing chamber.

[0010] Preferably: the filter frame is equipped with a detachable activated carbon block.

[0013] 2. When the utility model is used, the gas flow rate is slowed down through the fan-shaped guide cavity, and the gas in the arc-shaped chamber can be led upward by using the inclined guide cavity hole, so as to reduce the direct contact between the reflux gas and the staff, increase the difficulty of the reflux of high-density gases such as carbon dioxide, and add corresponding processing equipment or processing media in the inner circulation gas treatment chamber separated by the filter frame, similar to the inner circulation disinfection procedures such as alcohol ultraviolet sterilization, and then through the filter frame formed by the activated carbon block, the impurities in the air are efficiently filtered, the cleanliness of the inner circulation airflow is increased, the air quality is guaranteed, and a stable, reliable and efficient clean environment is provided.
