Description

Air nozzle accessory and blower Technical Field The utility model relates to the field of electric appliances, in particular to a tuyere accessory and a blower. Background With the improvement of people's demand of blowing hair, high-speed hair-dryer is because of having higher power and wind speed, can shorten the time of doing the hair by a wide margin through strong wind-force, so the favor of people more and more. The air outlet of the blower can be connected with a tuyere accessory, and the tuyere accessory can improve the air speed of air flow and concentrate the air flow, thereby achieving the modeling purpose. However, the conventional high-speed blower nozzle often blows high-speed and concentrated air flow, and the high-speed air flow and surrounding air at the air outlet are subjected to severe interaction to form strong turbulence and pressure fluctuation, so that high pneumatic noise is generated. In addition, the high-speed and concentrated air flow can cause the conditions of overlarge local air speed and overhigh temperature, so that certain damage is caused to the hair and scalp of a user, and meanwhile, the experience of the user is influenced.
