With the increase of income level and the improvement of housing conditions, air conditioners are popularized to restaurants, hotels, dormitories, offices and ordinary people at a rapid speed. However, along with the popularization of air conditioners, the following air conditioner diseases also attract attention. The reason of the 'air conditioning disease' is that besides the indoor air is not circulated, the air conditioning is mainly caused by that after the air conditioner runs for a long time, a large amount of impurities (such as dust, fibers, oil smoke and the like) in the air can be deposited on a filter screen and a radiating fin of the air conditioner, and meanwhile, a good hotbed is provided for breeding bacteria and mould in a wet and cold environment, so that the indoor air quality is poor, the human body feels uncomfortable, and the like. Therefore, the air conditioner needs to be cleaned regularly, and the cleaning effect of the air conditioner directly affects the health of the user.

At present, air conditioner cleaning agents are generally used in the market to clean air conditioners, and common air conditioner cleaning agents are in a hand spray type and in an aerosol type. The hand spray type is complex to operate, large in labor consumption and limited in cleaning coverage; the traditional aerosol is convenient to operate, but liquid is sprayed out in a foam form, so that various fine unit liquid-gas interfaces are formed on the surface of an object, the spreadability and the permeability are poor, and the cleaning effect on tightly adhered dirt is poor. Meanwhile, because the dust is easy to float and not easy to be caught, the traditional air conditioner cleaning agent has poor effect of removing the dust in the air conditioner.
