Preferably, the material of the cylindrical structure of the flow guide device is PA66+ GF, wherein the mass ratio of GF is 15-35%; or the cylindrical structure of the flow guide device is made of other high-temperature resistant materials with the thermal deformation temperature of more than 200 ℃.
Preferably, the outer wall of the tubular structure of the flow guide device is further provided with a reinforcing rib.
Preferably, the top of the flow guide device is further provided with a noise reduction structure, and the noise reduction structure is a honeycomb grid rib.
Preferably, the guiding device is further provided with a noise reduction structure, and the noise reduction structure is specifically a honeycomb grid rib directly arranged on the gooseneck-shaped outer wall of the guiding device.
Preferably, the grid shape of the honeycomb grid ribs can be circular, oval or polygonal and is uniformly distributed.
The invention relates to a flow guide device of a blowing rod, which has the advantages and effects that: the flow guide device simulates a gooseneck structure, so that the loss of air quantity and air pressure is reduced to the maximum extent when the wind direction needs to be changed; meanwhile, the extra noise generated when the wind direction changes can be reduced; the guide grid is added in the inner part, so that the noise can be further reduced; this guiding device not only can reduce wind noise through increasing cellular net muscle, and cooling down with higher speed more can reduce the impact to the long-term high temperature of wind channel outer wall that causes because of the wind direction change, prolongs this guiding device and the whole life who bloies the stick, is favorable to providing a portable, the utensil of drying out of breakthrough outward appearance.
