Description

Technical Field

[0001] The utility model relates to the technical field of cleanroom doors, in particular to a lightweight sealed cleanroom door. Background Art

[0002] Cleanroom doors are used in clean rooms with relatively high cleanliness requirements. Minimizing dust accumulation and ensuring the sealing of cleanroom doors are one of the important methods to improve the cleanliness of cleanrooms. Existing cleanroom doors have certain gaps at their joints to ensure the normal opening and closing of cleanroom doors, but this cannot ensure the sealing of cleanrooms. Therefore, in order to improve the cleanliness of cleanrooms, people have invented patent number: CN201620960896.2, which discloses a new type of cleanroom door. The cleanliness of the cleanroom door is improved by a silicone sealing magnetic strip. The buzzer alarm on the cleanroom door can also prompt whether the cleanroom door is closed. The cleanroom door adopts a multi-layer structure, which greatly improves the purification efficiency of the cleanroom door, thereby improving the cleanliness of the cleanroom. The utility model also has the advantages of compact structure and complete functions. However, the clean room door still has the following problems: 1. When the clean room door is opened from the door frame, this action will generate airflow, and the flow of airflow will cause dust and other impurities to flow into the clean room door, and then flow into the room inside the clean room door, reducing the indoor purification effect; 2. In order to ensure the sealing of the existing clean room door, most of them adopt the method of ensuring the fit between the clean room door and the door frame. In order to ensure the fit and prevent the deformation of the clean room door, the existing method is to increase the thickness of the plate to ensure the overall shape of the clean room door. This method increases the overall weight of the clean room door and is inconvenient to transport and install; 3. A sealing rubber ring is used between the existing clean room door and the door frame for sealing, but the sealing rubber ring is aged, skewed or offset, which affects the connection sealing and thus affects the dustproof effect.
