Abstract

The invention relates to the field of wind supply, and particularly discloses a wind supply fan with a noise reducing function. The problems that an existing fan is inconvenient to fix and has comparatively large vibration and noise when the existing fan is used are solved. According to the following scheme, the wind supply fan comprises a fixing base plate, wherein movable wheels are arranged atthe four bottom corners of the fixing base plate, four groups of supporting springs are connected to the position between the fixing bottom plate and the supporting plate, two groups of buffering assemblies are connected to the position between the fixing bottom plate and the supporting plate, the two groups of buffering assemblies comprises four groups of first connecting rods and four groups ofsecond connecting rods, one ends of the first connecting rods are hinged to the bottom of the supporting plate, and one ends of the first connecting rods are hinged to the upper side of the fixing base plate. The wind supply fan with a noise reducing function is reasonable in structure and novel in design, the fan can be quickly and easily fixed to the supporting plate, and through the supportingsprings and the buffering assemblies between the supporting plate and the fixing base plate, the vibration of the fan can be effectively buffered, and the noise can be reduced.

Description

technical field [0001] The invention relates to the field of air supply fans, in particular to an air supply fan with a noise reduction function. Background technique [0002] The fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine. The main structural components of the fan are the impeller, the casing, the air inlet, the bracket, the motor, the pulley, the coupling, Mufflers, transmission parts (bearings), etc., when the existing fan is in use, it is usually set on the bracket, and the passage between the fan and the bracket is usually directly connected by screws, and the screws are easy to rust during the process, resulting in the fixing of the fan and the It is inconvenient to disassemble, and when the fan is in use, it vibrates greatly and generates a lot of noise. Therefore, we have designed an air supply fan with noise reduction function to solve the above problems. Contents of ...
