Duct cleaning tools

Abstract

Even if the duct to be cleaned is long or has a duct structure with many bends, the system will ensure that cleaning can be performed thoroughly all the way to the end of the duct. [Solution] A oscillating member 21 is connected to the tip of a pressure hose 1 that supplies cleaning air, and oscillates when air is sprayed, striking the inner surface of the duct 7 to clean it. Multiple flexible elongated bodies 3, which have higher rigidity than the pressure hose 1, are interconnected and extend in the longitudinal direction, holding the pressure hose 1. The pressure hose 1 is a single hose, and has the flexibility to bend 180 degrees when the connections are released and each flexible elongated body 3 is bundled together.

Claims

1. A duct cleaning tool used to clean the inner surface of a duct, A pressure hose that supplies air for cleaning, A swaying element connected to the end of the pressure hose, which oscillates and strikes the inner surface of the duct when air is sprayed from the pressure hose, A flexible elongated body extending in the longitudinal direction of the pressure hose and It is equipped with, A duct cleaning tool characterized by a flexible, elongated body that holds the pressure hose with higher rigidity than the pressure hose itself.

2. The duct cleaning tool according to claim 1, characterized in that a plurality of the aforementioned flexible elongated bodies are provided, and each flexible elongated body is connectable in the longitudinal direction.

3. The duct cleaning tool according to claim 2, characterized in that the pressure supply hose is a single hose that extends while being held by each flexible elongated body.

4. The duct cleaning tool according to claim 3, characterized in that the pressure supply hose has the flexibility to bend 180 degrees when the connections between the flexible elongated bodies are released and the flexible elongated bodies are bundled together.
