Brush fitting for hair dryer - has projections forming teeth on walls and openings for escape of hot air

摘要

The nozzle consists of a hollow cylindrical body with thin walls (20). The wall has pointed projections (3) which form the brush and openings (4) which alternate with the projections. The body is closed at one end (6) but the hot air is channelled (7) down on to the brush. There are also holes (5) at the base of the body which lower the pressure of the air entering the brus.
