Detailed Description

To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete. It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

As shown in fig. 1-3, the dustproof fan of the present embodiment includes a protective cover 1, a fan cover body, and a fan blade assembly disposed in the fan cover body; the fan cover body comprises a face mask 3, a connecting piece 4 and a bottom mask 5; the mask 3 is arranged at the top of the connecting piece 4; the bottom cover 5 is arranged at the bottom of the connecting piece 4; a clamping cavity (not shown) for accommodating a dustproof filter disc (not shown) is formed between the protective cover 1 and the face mask 3.

Specifically, the fan blade assembly comprises a leaf 12 and a drive motor 2 for driving the leaf to rotate; the face mask 3 can play a role in supporting the dustproof filter disc. Through with the fixed centre gripping of dustproof filter element between the centre gripping chamber, can avoid the in-process that uses, the condition that the dust cover drops. Through making protection casing 1 and connecting piece 4 can dismantle and be connected, can change protection casing 1, convenient to use.

As shown in fig. 1 to 3, in the dust-proof fan according to the embodiment, the protective cover 1 is in threaded connection with the connecting piece 4.

The threaded connection universality is strong, and the assembly is very convenient without the help of external tools.
