Description

Technical Field

[0001] This utility model specifically relates to the field of air conditioning equipment technology, and more specifically to a new type of air conditioning filter. Background Technology

[0002] An air conditioner, or air conditioner, consists of four parts: a refrigeration (heating) circulation system, an air circulation and ventilation system, an electrical control system, and a casing. It is an air conditioning unit that maintains a certain temperature, humidity, airflow speed, cleanliness, and freshness of the air in the regulated space. After a period of use, air conditioner filters often accumulate a large amount of dust and grime, producing bacteria and viruses that circulate with the indoor air, harming health. Therefore, air conditioner filters need to be removed and cleaned regularly. Most existing air conditioner filters are fixed inside the air conditioner with screws or simple clips. Screw-fixed filters require tools for removal, making the process cumbersome and potentially damaging to the air conditioner casing. Traditional clip-on filters often become difficult to remove after prolonged use due to dust accumulation, causing inconvenience for users during cleaning and maintenance, and affecting the air conditioner's performance and lifespan.
