Design Background
1. According to analysis and comparison, high-performance hair dryers have more efficient dry hair efficiency than traditional hair dryers, while causing less damage to hair and being more expensive;
2. Dyson's high-performance hair dryer leads the hair dryer industry, and at the same time, the hair dryer accessories are well enough, but the price is very expensive, so that the public is discouraged;
3. The daily use of high-performance hair dryer although the air volume is very large, but the noise produced by people have a more obvious sense of discomfort;
Through market research, it is found that the penetration rate of high-performance hair dryers in overseas markets is low, and the price of high-performance hair dryers is generally relatively high. The mainstream market is still dominated by traditional hair dryers, so a relatively cheap, affordable, low-noise, high-performance hair dryers have good market opportunities in overseas markets.

Design focus
1. Reduce noise, change the sound quality of noise, and reduce the discomfort of noise to users through the four-fold noise reduction design; 2. Realize the hair care requirements of various hair dryers through the form of air nozzle 1 1 1, and reduce the cost of accessories at the same time; 3. The diffuser improves the uniformity and softness of the air outlet of the diffuser through the design of the built-in soft air net and four circular partitions, and realizes better dry hair effect; 4. Through the simplification of product design, reduce the surface treatment of products to achieve environmental protection, reduce the effect of cost;

Differences from competing products, improved functionality
1. The noise of Dyson hair dryer is high-frequency, which makes people feel more uncomfortable. Sushi's hair dryer has a four-fold noise reduction design, which makes the noise lower frequency and more comfortable;
2. Compared with Dyson and Leffin competitors, we ensure the performance requirements of the product while ensuring the beauty of the product, and reduce the surface treatment of the product to achieve environmental protection and cost reduction;
3. The diffuser improves the uniformity and softness of the air outlet of the diffuser through the design of four circular partitions. After laboratory comparison and experience, it has a higher improvement than the competition;
4. The front end of the smooth nozzle is designed by inserting the buckle to realize the functional form of 1 1 accessories, by inserting a narrower nozzle module into a modeling nozzle, by inserting an anti-fly module into an anti-fly nozzle, through this form of structure, to achieve the purpose of reducing costs;
