Abstract
A dust collecting device (100) installed inside of an air conduit (51) for collecting airborne particles and for filtrating the air consists of a dust collecting tubes set (1). Said dust collecting tubes set (1) comprises of a plurality of dust collecting tubes (2a-2f) having different diameters. Said tubes (2a-2f) are arranged in a concentric fashion by having a tube with smaller diameter covered by one having larger diameter. Each of said dust collecting tubes (2a-2f) is applied with a layer of adhesive layer (3) for coupling with each other and for adhering particles contained in the air. Each tube of the tube set (1) can be removed from said air conduit (51) by pulling a pull string (4a-4f) provided at two extreme ends of each dust collecting tube (2a-2f).
Claims6
A removable dust collecting device (100) for an air conduit consists essentially of:
- a dust collecting tubes set (1);
- the set (1) is provided about an inner wall of an air conduit (51);
- said set (1) includes a plurality of hollow dust collecting tubes (2a-2f) made of soft material and having different diameters;
- said dust collecting tubes (2a-2f) are arranged in a concentric fashion by covering the one having small diameter with another one having larger diameter;
- the tubes (2a-2f), after collecting dust fully, are removed from the air conduit (51) sequentially from an innermost tube;
- an adhesive layer (3) is applied on each inner surface (21a-21f) of said dust collecting tubes (2a-2f) and on an outer surface (22f) of the outmost dust collecting tube (2f) for attaching each other and collecting dust;
- and
- an intake (24a-24f) is provided respectively at an end of said dust collecting tubes (2a-2f) where is about an air conditioning unit (5);
- an outlet (25a-25f) is provided respectively at an end of said dust collecting tubes (2a-2f) where connected to an air conditioning tube (51), and a pull string (4a-4f) is provided longitudinally on said dust collecting tubes (2a-2f) and extended from two extreme ends hereof for removing the tubes (2a-2f).
