AI Technical Summary

Technical Problem

Existing tandem cooling fans require frequent use of tools to secure screws during installation, resulting in low assembly efficiency and high installation precision requirements. This can easily lead to fan vibration or increased noise due to misalignment of holes. In addition, the lighting effects lack an integrated design, affecting aesthetics.

Method used

The design incorporates light guides, fixing components, and dustproof components. The fan can be quickly fixed using a plug and ball bearing structure. The light guides achieve a continuous lighting effect, while the dustproof mesh prevents dust from entering and reduces noise and vibration.

Benefits of technology

It improves the assembly efficiency of the fan, reduces fan vibration and noise, achieves a continuous flow effect of light, and enhances the overall aesthetics and ease of use.

Abstract

This utility model relates to the field of cooling fan technology and discloses a series of cooling fans, including a first housing, a second housing disposed on one side wall of the first housing, a light guide disposed between the first housing and the second housing, a fan base fixedly connected inside the second housing, a rotating sleeve fixedly connected to the side wall of the fan base, and blades fixedly connected to the side wall of the rotating sleeve. A fixing assembly is disposed inside the first housing, and a dustproof assembly is disposed on one side wall of the first housing; the fixing assembly includes a fixing sleeve and a plug rod. In this utility model, the light guide is snapped onto the first housing via a speed display screen, and the connection between the upper and lower housings is completed by inserting the plug rod into the fixing sleeve. By inserting the mounting sleeve into the chassis mounting position, rotating the throttle drives the threaded block to move into the mounting sleeve, compressing the spring and pushing the push block forward to squeeze the ball bearing, which engages with the inner wall groove of the chassis mounting hole. This structure improves the fan assembly efficiency.
