Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a dust-proof brushless fan. Background Art

[0002] A fan is a driven fluid machine that relies on input kinetic energy to increase the pressure of gas, thereby discharging it. Fans are primarily used for ventilation in various sectors of the national economy, including metallurgy, petrochemicals, automotive, electric power, urban rail transit, textiles, and shipping, as well as in various locations. For smaller equipment (such as household appliances) or in confined spaces, micro fans are often required.

[0003] The internal components of existing brushless fans (such as bearings and motors) are easily exposed to air containing dust, impurities and other pollutants. These pollutants will adhere to the surface of the components, increase friction between the components, lead to increased wear, and thus affect the overall performance and life of the fan.

[0004] Therefore, a dust-proof brushless fan is proposed to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the present invention is that the existing technology has the disadvantage that dust easily affects the overall performance and life of the fan. For this reason, we propose a dust-proof brushless fan.
