Description

[Technical field]

[0001] The utility model relates to a hair dryer. [Background technology]

[0002] When we cut hair, wash hair or take care of hair, we usually use a hair dryer. The hair dryer is equipped with a fan. When the fan blades rotate, the air is sucked in by the negative pressure on the air inlet side, and the air is blown out on the air outlet side. In order to prevent foreign objects from being sucked into the fan, a mesh is usually set on the air inlet side to prevent slightly larger objects from being sucked in. However, when we use a hair dryer to blow hair, the hair may touch the air inlet. Since the hair is very thin, it is difficult to ensure that the hair is not sucked in with only one mesh.
