[0002] Central air conditioning refers to a large air conditioning device that generates heat (cold) source from an outdoor unit or outdoor unit and supplies heat (cold) to each room. Central air conditioning is installed in many large waiting rooms, office buildings, and high-end residential areas to replace traditional independent air conditioning. It not only meets the basic living needs of users, but also significantly reduces the power consumption of central air conditioning, which meets the requirements of sustainable development for the construction of modern social infrastructure;

[0003] After the outdoor unit of the central air conditioner generates heat (cold) source, it supplies heat (cold) to the room where the indoor unit is installed through the pipe. After the pipe has been used for a long time, particles such as haze and dust in the air adhere to the inner wall of the pipe, affecting the air quality of the room where the indoor unit is located. Therefore, the inner wall of the pipe needs to be cleaned;

[0004] In some existing technologies, disinfectant water or cleaning water contains tiny particles or sediments, which are difficult to filter effectively. These particles are easy to accumulate in the pipes, causing pipe blockages and reducing the operating efficiency of the air-conditioning system. In addition, using disinfectant water to disinfect the central air-conditioning pipes while cleaning them may cause the air blown out by the central air-conditioning to have a strong smell of disinfectant water for a period of time after cleaning, causing users to feel uncomfortable. Therefore, we need to propose a central air-conditioning pipe cleaning and disinfection device. Utility Model Content
