[0002] As we all know, air conditioning is a device system used to regulate indoor temperature, humidity and air quality. Through air conditioning, people can keep the indoor temperature cool and comfortable in hot summer and keep the indoor temperature warm in cold winter. It not only provides a comfortable indoor environment, but also helps to improve air quality and eliminate problems such as moisture or dryness. The air conditioner outdoor unit is usually placed outdoors and is prone to the accumulation of dust, dirt, fallen leaves and other debris, which may affect its performance and efficiency. At this time, it is often necessary to use a cleaning device to clean it. The cleaning device refers to a tool, equipment or appliance used to clean the air conditioner outdoor unit or other equipment. They can assist in removing dirt, dust and blockages on the outdoor unit to maintain equipment performance and efficiency.

[0003] However, the external unit cleaning device of traditional air conditioner maintenance is generally large in size. If the space at the location of the air conditioner external unit is limited, the cleaning device may not be able to fully enter, resulting in poor cleaning effect or inability to clean thoroughly. In addition, the external unit cleaning device of traditional air conditioner maintenance can usually only perform simple flushing and cannot remove stubborn dirt or grease on the surface of the external unit. For stains that are difficult to remove attached to the external unit, such as oil stains, dust accumulation, etc., it may not be possible to achieve a thorough cleaning effect. Therefore, technical improvements are urgently needed. Utility Model Content
