Mini Handheld Fan Manufacturing in Vietnam
Mini Handheld Fan Manufacturing in Vietnam
In the production of mini handheld fans, the number of blades and wind speed levels are not simply random choices. They are the result of aerodynamic calculations aimed at providing a smooth yet powerful airflow. MyMy Technology We are constantly improving the fan blade structure to optimize the user experience for Vietnamese users.
1. What is the best size for a mini handheld fan in terms of blades? - MyMy Technology
The number of fan blades directly affects it airflow and smoothness of the wind flow:
- Mini 3-blade fan:This is the most popular type thanks to its advantage of creating a strong, focused airflow. With a large blade area, the 3-blade fan helps push air further, making it very suitable for outdoor activities.
- Mini fan with 4-5 blades:This design helps to "divide" the airflow, creating a smoother and more even breeze, minimizing the feeling of harsh wind on the face. This is an ideal choice for office workers or use in enclosed spaces.
- Multi-bladed fans (7 blades or more):Commonly found in high-end fan models, the increased number of blades allows for smoother operation, minimizing noise and creating an airflow that mimics natural wind, providing a comfortable experience even during prolonged use.
2. How does the number of blades affect the wind? - MyMy Technology
Many people wonder, "Does having more blades make it cooler?" The answer lies in balance:
- Contact area:More blades allow for a more continuous cutting of air, creating a stable airflow, but the wind pressure may be lower compared to fans with fewer blades if the motor power remains constant.
- Noise level:The more blades a fan has, the quieter it operates (because the sound frequency is pushed up to a level less sensitive to the human ear). At the factory, we usually prioritize 5-7 blade models for fans that require quiet operation.
3. Wind speed levels and adjustment options - MyMy Technology
A modern "Made in Vietnam" mini fan doesn't just have one on/off switch. MyMy Technology integrates a multi-level control circuit:
- Level 1 (Light Wind - Sleep Wind):Wind speed is approximately 2 - 3 m/sSuitable for children or for use while sleeping, ensuring no stuffiness or dryness in the nose.
- Level 2 (Moderate Wind - Natural Wind): Speed 4 - 5 m/s Suitable for office workers and students sitting in class, providing just the right amount of ventilation.
- Levels 3-5 (Strong Wind):Speed achieved above 6 m/s. This is the maximum power setting for adults when moving around in strong sunlight or after strenuous exercise.
4. Appropriate wind speed for each target group.
We design our products based on the actual needs of the Vietnamese market:
- Mini fan for children:Prioritize designs with thick fan cages (safe for fingers) and gentle wind speeds to avoid causing thermal shock to children.
- Mini fan for adults:Flexibility is essential. The ability to adjust from a gentle breeze to a strong wind gives users more control in any situation.
5. Control technology at MyMy Technology
To achieve precise speed levels, we use:
- PWM controller circuit:It helps to change motor speed smoothly, without jerking, and saves more energy compared to traditional resistor circuits.
- Smart button:Integrated level indicator lights or LED displays show wind speed, making it easy for users to monitor.
