A limiting component for fixing the frame 1 is provided on the mounting rod 3, and a fixing plate 4 is provided at one end of the mounting rod 3. The fixing plate 4 is convenient for fixing the mounting rod 3 to improve the use effect. A mounting hole is provided on the fixing plate 4, which can be fixed to the wall with screws or fixed to the wall with double-sided tape. Moreover, the mounting rod 3 and the fixing plate 4 are made of stainless steel, which can improve corrosion resistance. A solid alkali layer 202 is fixedly provided in the frame 1, and a filter screen 2 is fixedly provided at the top and bottom of the solid alkali layer 202. When in use, by setting the frame 1 at the return air inlet of the air conditioner and fixing the filter screen 2 in the frame 1, larger particles in the air can be reduced from entering the solid alkali layer 202, thereby improving the filtering effect of the solid alkali layer 202. Moreover, the solid alkali layer 202 can effectively adsorb formaldehyde, odor and some bacteria and viruses in the air, thereby purifying the gas entering the air conditioner and improving the use effect.

[0030] The solid base layer 202 may also be replaced by an activated carbon layer.

[0031] Reference Figure 3 A HEPA filter 201 is fixed on the top of the solid alkaline layer 202, and the top of the HEPA filter 201 is offset against the bottom of one group of filters 2, that is, against the filter 2 above the solid alkaline layer 202.

For the case where the length of the air-conditioning return air outlet is long, two or more groups of frames 1 can be connected in sequence to improve the use effect.

[0033] Reference Figure 1 and Figure 2 An adjusting rod 401 is fixedly provided on the fixing plate 4, and a rotation groove 302 is opened on one end of the mounting rod 3. The end of the adjusting rod 401 away from the fixing plate 4 is rotated and set in the rotation groove 302, and an adjusting component for limiting the rotation of the adjusting rod 401 is provided on the mounting rod 3. When in use, by rotating the adjusting rod 401 on the mounting rod 3, the angle between the fixing plate 4 and the mounting rod 3 is conveniently adjusted, thereby improving the applicable environment of the mounting rod 3.

[0034] Reference Figure 1-Figure 3 The adjusting component can use a buckle to fix the adjusting rod 401 on the mounting rod 3. Here, we design the adjusting component as a screw 5, and a through hole is opened in the adjusting rod 401. One end of the screw 5 passes through the through hole and is threadedly connected to the mounting rod 3 to fix the adjusting rod 401 on the mounting rod 3.
