Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a modular energy-saving fan. Background Art

[0002] In today's diversified industrial production and many key areas such as the construction of various building environments and the operation of ventilation systems, fans, as an indispensable basic equipment, have always played a vital and irreplaceable key role. It is like a hero who works silently behind the scenes. In industrial scenarios, whether it is the production workshop of a large factory, in order to ensure the normal heat dissipation of production equipment and maintain a good working environment air quality, the fan continues to operate to ensure the circulation and circulation of air, and to help the smooth progress of the production process; in the construction field, from the central air-conditioning ventilation system of high-rise buildings to the indoor air conditioning of ordinary residences, fans play a core role in creating comfortable living and working spaces for people; in the ventilation field, whether it is air replacement in underground parking lots or ventilation needs of various commercial places and public facilities, fans are the key driving force for achieving effective air flow. Its wide range of applications and continuous and stable operation are directly related to many key factors such as production efficiency, personnel comfort and environmental quality in various fields. Therefore, it occupies a vital position in the entire technical system and actual application scenarios, and plays an indispensable supporting role in promoting the development of various industries and ensuring people's quality of life.

[0003] The structural design of existing fans is not rational, resulting in poor stability during operation. The installation method of internal components of the fan may not be scientific enough, making them prone to displacement or loosening when facing airflow impact, vibration or other external forces. This not only affects the normal operation of the fan, but also shortens its service life. At the same time, energy efficiency is also an important concern. Many fans usually operate at a fixed power when in operation, and cannot flexibly adjust the air volume according to the needs of actual working scenarios. This results in some situations where the air volume demand is relatively small, and the fan still operates at a higher power, resulting in a large amount of energy waste and increased usage costs. To this end, a modular energy-saving fan is proposed. Utility Model Content
