[0011] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0012] like Figure 1 , Figure 2 As shown, this fan includes a fan body 1. The fan body 1 has an air outlet for discharging air and an air inlet for inleting air. An air knife 2 for discharging air is provided on the fan body 1 at the air outlet. A fixing part 3 is provided on the fan body 1 relative to the air inlet. A filter frame 4 for filtering is provided on the fixing part 3. The outer side of the filter frame 4 has a mounting ring 5. Several positioning rods 6 are provided on the mounting ring 5. A connecting part 7 that mates with the positioning rods 6 is provided on the fixing part 3. The upper part is provided with a positioning component 8 for positioning the positioning rods 6. The connecting part 7 has a slot, and each positioning rod 6 extends into the slot and is positioned by the positioning component 8 on the connecting part 7. The positioning component 8 consists of a positioning element 9, a connecting rod 10 and a return spring 11. The connecting part 7 has an installation slot for installing the positioning component 8. The positioning rod 6 has a positioning hole 12 that cooperates with the positioning element 9. The positioning rod 6 is fixed by the positioning element 9 retracting at the installation slot, thereby fixing the filter frame 4 to the fan body 1.
