Description

Technical Field

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

[0002] A purification system refers to a system that has a certain degree of self-purification and absorption capacity for environmental pollutants. The air outlet of the purification system is equipped with a filter device to help filter some pollutants. In the current field of air purification, the filter device of the air outlet of the purification system plays a crucial role, and its performance is directly related to indoor air quality and the production environment standards of many industries.

[0003] However, traditional devices typically employ complex housing designs. To ensure airtightness and prevent unfiltered air from bypassing, the housing is often tightly secured by multiple bolts or clips. When the filter needs to be replaced, maintenance personnel must first spend a significant amount of time disassembling these connecting parts one by one. This process is tedious and prone to errors. To disassemble the housing, maintenance personnel may need to use various specialized tools to unscrew a dozen or even dozens of bolts in sequence. This process is often very time-consuming, resulting in a significant reduction in the device's maintenance efficiency.

[0004] Therefore, it is necessary to provide a filter device for the air outlet of a purification system to solve the above-mentioned technical problems. Utility Model Content
