[0002] In contemporary buildings and industrial production environments, ventilation systems play a vital role. Exhaust ducts, as the key transmission channel of the ventilation system, are responsible for discharging polluted air, smoke, dust and heat, etc. They are of great significance to ensuring indoor air quality, maintaining appropriate temperature and humidity, protecting personnel health and normal operation of equipment.

[0003] With the large-scale construction of various large commercial buildings, industrial plants, and office buildings, ventilation systems have become increasingly complex, and exhaust duct networks have continued to expand and refine. In industrial scenarios, industries such as chemical, steel, and building materials generate massive amounts of waste gas and dust every day.

[0004] Traditional technologies often rely on a single cleaning method or simple cleaning tools to clean ventilation ducts, which makes it difficult to perform deep cleaning of ventilation ducts and to remove dirt on the inner wall of the duct more comprehensively and deeply. At the same time, most existing cleaning devices are of fixed specifications and cannot be flexibly adjusted according to the actual size of the duct. The ventilation ducts in actual working conditions have complex directions and diverse layouts. Existing cleaning technologies lack a clever adaptive design like the present invention, making it difficult to cope with a variety of duct layouts and size changes, and their versatility is seriously insufficient.

[0005] Based on this, the utility model designs an exhaust pipe cleaning structure to solve the above problems. Utility Model Content
