Problems solved by technology

[0003] During the use of the fan, people found that the noise of the equipment with the fan for heat dissipation and cooling is often relatively large. When the fan blade produces wind power, it will generate noise due to unnecessary extra vibration, which will affect the service life of the fan blade and affect people's life. Causing distress

Abstract

The invention discloses a silent fan. The silent fan comprises a body frame, wherein the body frame is fixedly connected with a motor; fan blades are rotatably connected with the motor; a group of tooth-shaped grooves are uniformly distributed in the edge of the body of the motor; a group of gaps are respectively formed in each vane of the fan blades; the tooth-shaped grooves are distributed symmetrically by taking the rotating shaft of the motor as a centre; two gaps are formed in each vane of the fan blades. According to the silent fan disclosed by the invention, the gaps and the tooth-shaped grooves which can absorb useless vibration are formed in the vanes of the fan blades and the body of the motor, so that the noises of the fan are greatly reduced.

Description

technical field [0001] The invention relates to a fan, more precisely, a silent fan. Background technique [0002] A fan, also known as an electric fan, refers to a device that generates wind power by driving the fan blades to rotate. With the development of science and technology, the use of fans is not only for heatstroke prevention and cooling of humans and animals, but also for cooling and heat dissipation of equipment by installing fans on some mechanical equipment and electronic equipment. [0003] During the use of the fan, people found that the noise of the equipment with the fan for heat dissipation and cooling is often relatively large. When the fan blade produces wind power, it will generate noise due to unnecessary extra vibration, which will affect the service life of the fan blade and affect people's life. Causing distress. Contents of the invention [0004] The invention mainly solves the technical problems existing in the prior art, thereby providing a s...
