Description

Technical Field

[0001] This utility model relates to the field of ventilation engineering fan technology, specifically a ventilation engineering fan that is easy to clean. Background Technology

[0002] Ventilation engineering refers to the scientific design, installation, and maintenance of a series of equipment and technologies to improve indoor air quality and ensure that people live and work in a healthy and comfortable environment. Fans play a crucial role in ventilation engineering, serving as key equipment for promoting air circulation, improving indoor air quality, and controlling temperature and humidity. They are widely used in industrial, commercial, and residential environments.

[0003] For example, when ventilating factory buildings in industry, the side-wall negative pressure forced exhaust method is usually adopted. In operation, negative pressure fans are installed on the side walls of the factory building, designed to allow for more than 40 air changes per minute in the workshop. Natural air supply is provided at the entrance of the workshop and the windows opposite to it to achieve air circulation, so that the high temperature and polluted air in the workshop is exhausted to the outside, and the naturally supplied fresh outdoor air enters the workshop to form a circulation system.

[0004] While the above methods are simple and practical, they only exhaust the air inside the factory and rely on natural air supply from outside to achieve ventilation. The cooling effect is not ideal. In addition, the fan blades are easily covered with dust, and it is usually necessary to remove the fan blades from the fan and clean them, which is a rather cumbersome operation. Therefore, a ventilation fan that is easy to clean is proposed to solve the above problems. Utility Model Content
