[0002] Heating and ventilation is a component of a building. It includes three aspects: heating, ventilation, and air conditioning. Heating and ventilation pipes have a very wide range of applications, such as purification system supply and return air ducts, central air conditioning ventilation pipes, industrial supply and exhaust ventilation pipes, environmental protection system suction and exhaust air ducts, mine gas drainage pipes, mine coated fabric air ducts, etc. Generally, there are no grooves at both ends of heating and ventilation pipes and they are equipped with sealing rings. During the heating process, various kinds of dirt will appear in the water supply pipe, which will accumulate continuously in the system pipeline network, resulting in problems such as narrow pipes, blockages, and water leakage. The device for cleaning scale inside a heating and ventilation pipe is a device specifically used to clean the scale inside heating and ventilation pipes (such as pipes in heating, ventilation, and air conditioning systems), which can clean the pipes efficiently, safely, and environmentally friendly to ensure the normal operation of the system.
