Abstract

The invention provides a handheld hair drier. The hair drier comprises a casing, a handle, a battery and a hair drying tube, wherein air inlets are formed in and a duct assembly is arranged on the casing, and the duct assembly comprises a duct connected with the casing, a motor and a fan; the motor and the fan are mounted in the duct; the casing is connected to the hair drying tube, by the duct assembly, and the battery is mounted on the casing. A center axis is defined on the hair drying tube, the area of the flowing cross section of an air duct at the back end of the fan at the position which is to the position of the air inlets along the direction of the axis is greater than that of the flowing cross section of the position of an air outlet in the hair drying tube, a flowing surface is formed between the inner wall of the casing and a hub of the fan, and the ratio of the flowing cross section of the position of the air outlet in the hair drying tube to the flowing cross section of the flowing surface at the position of the fan is greater than or equal to 0.8. The hair drying efficiency of the handheld hair drier provided by the invention is higher, and the requirement of a user is further satisfied.

Description

technical field [0001] The invention relates to a garden electric tool, in particular to a hand-held hair dryer. Background technique [0002] Hand-held DC hair dryers for gardens are mainly used to blow fallen leaves and small garbage near the ground, courts and stands. In order to blow up a large number of fallen leaves on the ground and some heavy garbage in the cracks, a large air volume of the hand-held hair dryer is usually required. However, due to the limitation of the air duct design, the hand-held DC hair dryer with the battery pack installed on the market currently The air outlet efficiency of the hair dryer is low, and the air volume of the hair dryer is small, which cannot meet the requirements of users. Contents of the invention [0003] The object of the present invention is to provide a high-efficiency hand-held hair dryer. [0004] In order to achieve the above purpose, the present invention provides a hand-held hair dryer, which includes a housing, a h...
