A pressproof fan structure includes: a fan frame having an upper case and a lower case; a support shaft having one end inserted into the lower case, and the other end protruding out from the upper case; an oil-retaining bearing having a bearing hole, in which the support shaft is fitted; a rotor assembly fitted around and connected with the oil-retaining bearing; a restriction member fitted around the support shaft near the oil-retaining bearing; a thrust member fitted around the support shaft near the oil-retaining bearing; and a stator assembly disposed on the lower case near the oil-retaining bearing without contacting.

Pressproof fan structure

An anti-press fan structure includes a fan frame and a fan impeller. The fan impeller has a support shaft supporting the fan impeller disposed in the fan frame. The support shaft has a protrusion section protruding from the fan frame to bear and connect with an external unit positioned above the fan impeller so as to keep an axial space between the fan impeller and the external unit. Accordingly, the fan impeller is prevented from being compressed by the external unit and the pressure applied to the fan frame is dispersed.
