[0002] Fan life testing refers to the process of evaluating the service life of fans (including household fans, industrial fans, etc.) and drive units through a series of scientific testing methods and equipment. This includes testing the durability of core components such as motors, bearings, shaking mechanisms, and external structures such as blades, control switches, etc.

[0003] However, when the existing fan life test is aimed at detecting the fan blade speed, a certain reserved space needs to be left in the limit component of the detection device to allow the fan blades and drive parts of different sizes to rotate. However, this rotation method results in the fan blades and the drive part being prone to falling off due to the lack of supporting force when the limit is released after the test is completed. As a result, the fan blades and the drive part are prone to damage due to the different heights of their reserved spaces, which reduces the protection of the fan blades and the drive part and makes them inconvenient to use. Therefore, we propose a computer fan life detection device with easy-to-use functions, which is urgently needed to be developed. Utility Model Content
