Description

Technical Field

[0001] This utility model relates to the field of air shower technology, specifically a clean air shower for purification engineering. Background Technology

[0002] Cleanroom engineering is a comprehensive technical system designed to eliminate contaminants such as microparticles, harmful gases, and bacteria by controlling parameters such as atmospheric cleanliness, temperature, humidity, and pressure within a specific space, thereby creating a high-standard production or experimental environment. Its core lies in designing airflow organization schemes using turbulent or unidirectional flow principles, combined with high-efficiency filtration systems (such as HEPA filters), temperature and humidity control equipment, and strict differential pressure management, ensuring that products in industries such as precision manufacturing, pharmaceuticals, and food processing can complete their production processes under dust-free and sterile conditions. This engineering not only involves air handling technology but also requires the coordinated operation of multiple subsystems such as interior design, HVAC, and electrical automation to meet the mandatory cleanliness standards or process requirements of different fields.

[0003] Cleanroom air showers are a key piece of equipment in cleanroom engineering. They create an "air barrier" through high-speed clean airflow, effectively removing dust particles, microorganisms, and other contaminants adhering to the surfaces of personnel or objects, preventing unpurified air from entering the clean area. Their core consists of a high-efficiency particulate air (HEPA) filter, a high-volume fan, and a precision nozzle system, capable of omnidirectional blowing at a wind speed of ≥25m / s. Combined with infrared sensors, they achieve automatic start / stop and adjustable blowing time control. These devices typically use stainless steel or electrostatically powder-coated steel panels for the enclosure, equipped with a double-door interlocking mechanism to ensure airtightness. Widely used in industries such as electronics manufacturing, pharmaceuticals, and food processing, they serve as the essential passageway before entering cleanrooms, fulfilling both the function of purifying personnel and materials and acting as an airlock to prevent cross-contamination.

[0004] Conventional air showers have a relatively complex structure, making assembly and use cumbersome. Moreover, ordinary air showers use single-layer filtration, which is not effective enough and affects the performance. Finally, the nozzles of ordinary air showers have a single direction, resulting in poor cleaning. Therefore, there is an urgent need for a cleanroom air shower that is easy to assemble and use, has multi-layer filtration, and allows the nozzles to rotate. Utility Model Content
