Description

Technical Field

[0001] The present application relates to the technical field of cleaning machinery, and in particular to a ventilation duct cleaning robot. Background Art

[0002] Since the central air conditioner has not been cleaned for a long time, a large amount of dust particles, microorganisms, bacteria, fungi, carbon dioxide, inhalable particles, etc. will accumulate in the ventilation and air conditioning system pipes in many public places, which will have an adverse effect on human health. Once the central air conditioner is used after being idle for a long time, a large number of deposited bacteria in the air duct will be blown out. After the human body inhales it, it will feel uncomfortable at the least and be infected with viruses at the worst. This is also an important root cause of human sub-health, respiratory diseases and allergic diseases. Secondly, according to the test analysis of authoritative organizations, due to the large amount of accumulation caused by the long-term non-cleaning of the central air conditioner, the air flow pattern in the air duct will change from the original laminar state to the flocculent state, increase the internal friction, hinder the wind force, increase the load of the fan, and reduce the unit capacity, thereby increasing energy consumption and reducing the service life of the air conditioning equipment. In the long run, it will increase the operating cost. Therefore, it is essential to regularly check the central air conditioning ventilation system and conduct a thorough cleaning.

[0003] The traditional manual cleaning method not only has a series of disadvantages such as high risk, heavy labor, low work efficiency, high economic cost, and high time cost, but also the dust generated during cleaning can easily cause damage to the workers' bodies. Therefore, designing a new mobile robot that is more suitable for ventilation duct work and cleaning is of great significance to the development of this field.

[0004] Achieve comprehensive cleaning, maintenance and inspection of ventilation ducts. Through the design and optimization of robot structure, sensor system and intelligent control, it brings disruptive innovation to the field of ventilation duct cleaning, improves cleaning efficiency, reduces labor costs, and provides important protection for the environmental health and safety of buildings.
