Hair Dryer Diffuser With Conical Airflow Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Most existing hair dryer diffusers have uneven airflow output at different positions, which affects the efficiency of hair drying.
Innovation Solution
A diffuser design that includes a shell with an air inlet, a first diffusion component with a first through hole, a second diffusion component with a conically contracted second through hole, and an air output component that guides airflow for even distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional diffuser design is used, then the structure is simple, but the airflow output is uneven at different positions
Solution Approach 1:
The diffuser is divided into multiple functional components: a shell, a first diffusion component with first through holes, and a second diffusion component with second through holes. This segmentation allows each component to control airflow at different stages, ensuring uniform distribution while maintaining manageable structural complexity
Solution Approach 2:
Different regions of the diffuser are designed with different characteristics: the first diffusion component has first through holes arranged to distribute airflow initially, while the second diffusion component has second through holes arranged to further distribute and uniformize the airflow. The conical contraction of the second through hole creates localized flow acceleration and mixing, ensuring uniform airflow output at different positions
2Productivity
If uneven airflow output is present, then the device complexity is low, but the hair drying efficiency is reduced
Solution Approach 1:
The diffuser is divided into multiple functional components: a shell, a first diffusion component with first through holes, and a second diffusion component with second through holes. This segmentation allows each component to control airflow at different stages, ensuring uniform distribution while maintaining manageable structural complexity
Solution Approach 2:
The second through hole is designed with a conical contraction shape, changing the geometric parameters of the airflow path. This conical shape accelerates and mixes the airflow, ensuring uniform distribution and improving hair drying efficiency

AI summary
Disclosure is a diffuser including shell, first diffusion component, second diffusion component, and air output component. The shell includes an air inlet, the air inlet is configured to receive an airflow from a hair dryer. The first diffusion component is detachably connected to the shell, includes a first through hole; the airflow flowing out of the air inlet passes through the first through hole. The second diffusion component is detachably connected to the first diffusion component, includes a second through hole; an inner surface of the second through hole is a conical surface contracted towards the first diffusion component; the airflow flowing out of the first through hole passes through the second through hole. The air output component is detachably connected to the shell and the second diffusion component, and is configured to guide the airflow flowing out of the second through hole to flow out of the diffuser.
