[0027] See also Figure 1-6A high-efficiency air supply outlet that is easy to install includes a static pressure box 2, a front cover plate 3 and a rear cover plate 1. A filter is arranged on the inner side of the static pressure box 2. A U-shaped clamping strip 10 is fixedly connected to the outer end of the static pressure box 2 close to the front cover plate 3. An inserting strip 20 is fixed to the connecting end of the front cover plate 3. Giving grooves 11 are provided on both sides of the upper end of the U-shaped clamping strip 10. A locking piece is arranged in the giving groove 11. The end of the inserting strip 20 is matched and connected with the locking piece. A filter plate is fixedly connected to the rear cover plate 1. An adjusting piece is arranged on the inner side of the rear cover plate 1. The adjusting piece is matched with the filter plate.

[0028] Specific working principle and implementation method: the static pressure box 2, the front cover plate 3 and the rear cover plate 1 form an air supply part, a filter is arranged on the inner side of the static pressure box 2, and foreign matter in the air is filtered through the filter, and the cross section of the U-shaped card strip 10 fixed on the outer ring of the static pressure box 2 is L-shaped, and the whole is U-shaped, and an insertion strip 20 is fixed at the connecting end of the front cover plate 3, and the insertion strip 20 is inserted into the gap between the U-shaped card strip 10 and the static pressure box 2, and the locking pieces in the giving way grooves 11 on both sides of the upper end of the U-shaped card strip 10 are matched and snapped with both sides of the upper end of the insertion strip 20, so that the front cover plate 3 can be completed. Installation, similarly, when the front cover 3 is disassembled, the locking piece can be opened to remove the front cover 3 outward, and the size of the air intake can be adjusted by the adjusting piece on the inner side of the rear cover 1, thereby reducing the wind speed and pressure in the static pressure box 2; the advantage of such a design is that the static pressure box 2 and the front cover 3 are plugged into each other through the U-shaped clip 10 and the insertion strip 20, and are fixed by the locking piece, and the locking pieces on both sides of the upper end of the U-shaped clip 10 can be operated to unlock the front cover 3, and the wind speed and pressure at the air inlet can be reduced by the adjusting piece, thereby reducing the impact of the wind on the filter plate.

[0029] like Figure 4 As shown, the locking member includes a fixing plate 12 fixed in the give way groove 11, the outer end of the fixing plate 12 is fixedly connected to the first spring 13, the two ends of the fixing plate 12 are slidably connected to the guide rod 15, the inner end of the guide rod 15 is fixedly connected to the abutment plate 14, the outer end of the guide rod 15 is fixedly connected to the pressure block 16, the upper ends of the inserting strip 20 are fixedly connected to the clamping strip 21, the lower ends of the U-shaped clamping strip 10 are fixedly connected to the blocking strip 17, and the lower ends of the inserting strip 20 are located on the inner side of the blocking strip 17; the fixing plate 12 is located between the two guide rods 15 and the inner ends of the guide rods 15 are fixedly connected to the clamping strip 21, and the lower ends of the U-shaped clamping strip 10 are fixedly connected to the blocking strip 17. The push plate 14 is located between the rods 15, the inner side of the fixed plate 12, and the pressing block 16 is located on the outer side of the fixed plate 12. When the front cover 3 and the inserting strip 20 are inserted into the U-shaped clamping strip 10, the clamping strip 21 is clamped at the inner end of the clearance groove 11, and then the outer pressing block 16 presses the first spring 13 inwardly to compress the first spring 13. The guide rod 15 pushes the push plate 14 inwardly to push the clamping strip 21 out of the clearance groove 11 to unlock the end of the inserting strip 20, and under the action of the first spring 13, the position of the pressing block 16 can be returned to its original position for the next use.

[0030] like Figure 3As shown, the filter element includes a fixed frame 4, the inner edge of the fixed frame 4 is provided with a placement groove 5, the four corners of the placement groove 5 are fixedly connected with a slide rod 6, a filter screen 7 is arranged in the placement groove 5, and the four corners of the filter screen 7 are provided with sliding holes 8 matching the slide rod 6, and the upper and lower ends of the outer side of the filter screen 7 are fixedly connected with arc-shaped spring pieces 9, and the arc-shaped spring pieces 9 are set against the inner side end of the front cover 3; the sliding holes 8 at the four corners of the filter screen 7 are inserted into the slide rod 6, and the filter screen 7 can be installed. The arc-shaped spring pieces 9 fixed on the outer side of the upper and lower ends of the filter screen 7 are against the inner side end of the front cover 3 to form a support. When the front cover 3 is removed, the filter screen 7 can be pulled outward by the arc-shaped spring pieces 9, which is easy to disassemble, and when the internal wind blows, the sliding of the sliding holes 8 and the slide rod 6 and the support of the arc-shaped spring pieces 9 can reduce the impact of the wind and extend the service life.
