[0001] This utility model relates to the field of HVAC purification devices, and in particular to a purification device for the air outlet of a hospital HVAC system. Background Technology

[0002] With the improvement of medical standards and people's increasing attention to the health environment, indoor air quality in hospitals has become an important factor affecting the speed of patient recovery and the work efficiency of medical staff. As a key link in indoor air circulation, the air outlets of hospital HVAC systems often become the transmission path of dust particles in the air. Therefore, purification devices are installed at the air outlets.

[0003] However, existing purification devices have many inconveniences in terms of installation and use. The filter plates in the purification devices usually require professional tools for installation and disassembly, which is complicated and not conducive to daily maintenance and cleaning. At the same time, the filter plates lack a stable fixing structure and are prone to loosening during long-term use, which affects the purification effect.

[0004] Therefore, considering the complex operation of filter plates during installation and disassembly in the above-mentioned purification devices and the lack of a stable fixing structure for the filter plates, which makes them prone to loosening during long-term use, a purification device for the air outlet of hospital heating and air conditioning can be designed. Through sliding and rotating structures, the installation and disassembly of the filter plates can be made simpler and faster, while also enhancing the stability of the filter plates.
