Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioning equipment cleaning technology, and in particular to an automatic cleaning device for the double-layer nozzle surface cooler of an air conditioning unit. Background Technology
[0002] The cigarette production process has strict requirements for environmental temperature and humidity. Excessive temperature can easily cause tobacco leaves to deteriorate and mold, while insufficient temperature may affect the physical properties of the tobacco leaves, such as reducing their flexibility and making them prone to breakage during processing. Regarding humidity, excessive humidity will cause the tobacco leaves to absorb too much moisture and become soft, affecting processing; insufficient humidity will cause the tobacco leaves to lose moisture and become dry and brittle. Air conditioning units, through their cooling, heating, humidifying, and dehumidifying functions, precisely control the temperature and humidity in the production workshop and warehouse, ensuring that cigarette production takes place in a suitable environment.
[0003] Furthermore, the air inside cigarette factories may contain tobacco dust, odors, and microorganisms. The air filtration system in the air conditioning unit can effectively remove dust and impurities from the air, preventing them from adhering to the tobacco or cigarette products and affecting product quality. At the same time, by introducing fresh air and air purification devices, air quality can be regulated, providing a healthy and comfortable working environment for production personnel and reducing employee health problems and decreased production efficiency caused by air quality issues. The need is even more pronounced in production areas with extreme environments. Therefore, cigarette production plants will definitely be equipped with air conditioning units.
[0004] As a crucial component of central air conditioning units used in tobacco systems, the surface cooler is prone to accumulating dust, dirt, and tar, affecting heat exchange efficiency. Traditional cleaning devices are mostly manual, making it difficult to efficiently complete cleaning and drying. Therefore, designing a dual-layer nozzle device capable of simultaneously spraying water and compressed air can effectively solve the problems in existing technologies. Utility Model Content
