Description

Double blowing fan structure

This creation is about a fan, especially a double-blowing fan structure.

According to the hot weather in summer, air-conditioning equipment is used indoors to quickly reduce the indoor temperature. However, due to the importance of environmental protection and energy saving and carbon reduction issues in recent years, air-conditioning equipment is equipped with fans in addition to increasing the set temperature. Use can also reduce power consumption, but still can not maximize the effectiveness of electric fans, in addition, using electric fans alone is also a common choice for cooling.

However, the current conventional fan is mainly driven by a motor to rotate a fan blade to generate air flow. Since a fan blade can only generate a single air flow, the air convection effect that can be achieved is limited and cannot provide effective air supply and heat dissipation. If multiple fans are installed , It occupies space and is inconvenient to use and store. More importantly, its adjustable blowing angle is limited, which cannot meet the needs of users, resulting in its practicality greatly reduced. Therefore, there is indeed a need for improvement.
