Description

Technical Field

[0001] The utility model relates to the technical field of silent fans, in particular to a high-efficiency box-type silent fan. Background Art

[0002] A fan is also called an electric fan. It is a household appliance that uses an electric motor to drive the blades to rotate to accelerate the circulation of air. It is mainly used to cool down and circulate air. It is widely used in homes, classrooms, offices, shops, hospitals, hotels and other places. Common household fans are essentially axial flow fans, that is, the direction of the wind is parallel to the rotation axis of the fan blades.

[0003] A silent fan disclosed in the Chinese utility model patent application disclosure CN208503078U solves the problem that the existing silent fans generate certain noise pollution when working, and the heat generated during working is dissipated, which easily causes certain energy waste. It includes a silent fan body, the outer side of the silent fan body is provided with a protective shell, one side of the protective shell is provided with an inner lining, one side of the inner lining is provided with sound-absorbing cotton, one side of the silent fan body is provided with a motor, one side of the motor is provided with a rotating bearing, the outer side of the rotating bearing is provided with a fan, the outer side of the fan is provided with fan blades, the bottom end of the silent fan body is provided with a base, and the top end of the base is provided with an upper shock-absorbing plate. The utility model has a novel structure and an ingenious design. It combines the shock-absorbing design and the reduction of airflow noise to achieve the silent effect of the overall structure, which can reduce the overall noise pollution. At the same time, the heat can be converted into electrical energy and stored in the battery, which is energy-saving and environmentally friendly and prevents energy waste.

[0004] However, the device lacks the function of facilitating maintenance. In actual use, when the device fails, it is difficult for the staff to maintain and replace the motor and fan inside the device. Not only that, the device also lacks the function of cleaning the filter. In actual use, the fan needs to use a filter when in use to prevent foreign matter from entering the device. However, after long-term use, a large amount of dust will accumulate on the filter, affecting the normal operation of the device. Utility Model Content
