Abstract
A spraying device includes a rotatable outer fluid transmission tube and an inner fluid transmission tube disposed in the outer fluid transmission tube. A friction reducing layer, rotated together with the outer fluid transmission tube, is provided between the outer fluid transmission tube and the inner fluid transmission tube. The friction reducing layer is made of a material having a low friction coefficient and has a smooth inner wall surface, so as to make a friction force between the friction reducing layer and the inner fluid transmission tube lower and improve the durability of the inner fluid transmission tube.
