Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleanrooms, and more specifically, to a cleanroom air supply device. Background Technology
[0002] A cleanroom is a well-sealed space where parameters such as air cleanliness, temperature, humidity, pressure, and noise are controlled as needed. Air vents need to be installed in a cleanroom to keep the air inside fresh.
[0003] In related technologies, to address the problem that in existing cleanroom high-efficiency air supply outlets, filters and diffusers are mostly fixed to the housing with screws, requiring numerous screws to be removed and tightened individually for filter replacement, which is inconvenient for disassembling and assembling diffusers and filters and results in low work efficiency, patent CN221259073U provides a cleanroom high-efficiency air supply outlet. This cleanroom high-efficiency air supply outlet incorporates a limiting structure; pressing the upper locking block activates a limiting block. Moving downwards causes the locking block to move the first spring downwards, and simultaneously pressing the lower locking block pulls the diffuser plate to the left, facilitating its disassembly and assembly. By incorporating a filter structure and a fixing structure, pulling the upper baffle to the left and rotating it 90 degrees counterclockwise or clockwise allows it to move back to its original position to the right. The fixing block's limitation on the cross block releases the filter, making it easy to disassemble and assemble. This method is highly efficient and simplifies the replacement of the guide roller body, allowing for easy removal of the guide roller body locked inside the support plate.
[0004] Cleanrooms are widely used in industries such as pharmaceuticals, electronics, and biotechnology, and have extremely high requirements for controlling airborne dust particles, microorganisms, and other pollutants. However, existing high-efficiency air supply outlets for cleanrooms have the following drawbacks: First, the air inside the cleanroom contains other dust impurities during use, leading to poor air quality inside the cleanroom during air supply. Second, it is inconvenient for staff to perform maintenance when replacing internal filters and filter cotton, thus increasing the workload of staff. In view of this, we propose a cleanroom air supply device. Utility Model Content
