Description

Technical Field

[0001] The utility model relates to an air duct structure of a hair dryer, belonging to the technical field of garden tools. Background Art

[0002] As described in patent CN212506041U, in daily life, a hair dryer is a relatively common tool, usually used to clean the ground such as gardens or streets. With the development of the times, people's demands for different functions of hair dryers are getting higher and higher. In order to improve the user experience, the hair dryer can provide sufficient air volume while achieving the effect of light weight, low noise and small vibration, and the siphon hair dryer came into being. The siphon hair dryer uses the pressure difference between atmospheric pressure and negative pressure to allow the external airflow to enter the siphon tube, thereby realizing supplementary airflow to increase the air volume. Therefore, too few supporting ribs of the air duct will cause the siphon tube to deform, and too many supporting ribs will lead to insufficient wind pressure, and the best effect of blowing cannot be achieved.

[0003] In order to avoid the above problems, the utility model provides a new air duct structure. Utility Model Content

[0004] The utility model aims to overcome the problems existing in the prior art and provides an air duct structure of a hair dryer, comprising: a first air duct and a second air duct, the second air duct being slidably sleeved on the outer wall of the first air duct, the second air duct extending outwardly with an expanded diameter siphon tube, the expanded diameter siphon tube being connected to the second air duct through a support member, the support member comprising three groups of parallel support ribs circumferentially arranged between the second air duct and the expanded diameter siphon tube, the arc length of the expanded diameter siphon tube between each group of support ribs being less than 70 mm, the arc length of the expanded diameter siphon tube between two groups of support ribs being greater than 70 mm, and each group of support members comprising more than two support ribs.

[0005] Furthermore, the pipe mouth of the expanded diameter siphon tube is covered with a soft rubber protective sleeve, and the pipe mouth of the expanded diameter siphon tube is provided with an embedding groove matching the soft rubber protective sleeve.

[0006] Furthermore, the soft rubber protective cover extends along the tangent line of the pipe opening to form a placement surface.

[0007] Furthermore, the second air duct and the first air duct are provided with matching buckles.

[0008] Furthermore, the outer wall of the second air duct is provided with guide ribs in the radial direction, and the inner wall of the first air duct is provided with sockets for the guide ribs to pass through.

[0009] The beneficial effects of the utility model include effectively solving the deformation problem of the enlarged diameter siphon tube and improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS
