Description

Technical Field

[0001] The utility model relates to the technical field of ventilation equipment, in particular to a protective structure of a ceiling ventilation fan. Background Art

[0002] The exhaust fan is a type of air conditioning appliance that uses an electric motor to drive the airflow by rotating the blades to exchange indoor and outdoor air. It is also called a ventilation fan. The purpose of ventilation is to remove the dirty air in the room and adjust the temperature, humidity and sensory effect. Exhaust fans are widely used in homes and public places. There are three types of ventilation methods for exhaust fans: exhaust, suction, and combined. The exhaust type takes in air from the natural air inlet and exhausts the dirty air through the exhaust fan; the suction type inhales fresh air through the exhaust fan and exhausts the dirty air from the natural exhaust port; the combined type is that both the suction and exhaust are completed by the exhaust fan. Most of the exhaust fans have a protective net fixed on the outer shell. Due to the accumulation of time, a large amount of dirt and other impurities appear on the protective net, so the protective net needs to be replaced and cleaned. Traditional exhaust fans are mostly integrated with the protective net and the housing of the exhaust fan. Therefore, when the protective net needs to be replaced, the entire housing must be replaced, making the replacement of the protective net troublesome. Utility Model Content
