The present utility model is not limited to the following specific embodiments. It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.

[0022] As Figures 1 to 4 shown, a filtering device for a central air conditioner includes: a mounting frame 100, a connecting mechanism, a filtering mechanism, and a fixing mechanism; a placement opening 110 and two limiting openings 120 are formed on the mounting frame 100, the filtering mechanism is disposed in the placement opening 110 through the connecting mechanism, a part of the fixing mechanism is located in one of the limiting openings 120, and another part is located in the other limiting opening 120, and the fixing mechanism is used to connect with an external ceiling.

[0023] Specifically, a ring of connecting plates 500 is provided on the mounting frame 100, and both of the two limiting openings 120 are formed in the connecting plates 500. The connecting mechanism includes a first mounting frame 210 and a second mounting frame 220. A first connecting ring 130 and a second connecting ring 140 are provided on the mounting frame 100. A first inserting block 211 is provided on the first mounting frame 210, and a second inserting block 221 is provided on the second mounting frame 220. The first inserting block 211 is detachably inserted into the first connecting ring 130, and the second inserting block 221 is detachably inserted into the second connecting ring 140. The first mounting frame 210 is provided with a plurality of first ventilation ducts 212, and the plurality of first ventilation ducts 212 are arranged at intervals. The second mounting frame 220 is provided with a plurality of second ventilation ducts 222, and the plurality of second ventilation ducts 222 are arranged at intervals. Four first inserting rings 213 are provided on the first mounting frame 210. Two of the first inserting rings 213 are arranged on one side of one surface of the first mounting frame 210, and the other two first inserting rings 213 are arranged on the other side of one surface of the first mounting frame 210. Four second inserting rings 223 are provided on the second mounting frame 220. Two of the second inserting rings 223 are arranged on one side of one surface of the second mounting frame 220, and the other two second inserting rings 223 are arranged on the other side of one surface of the second mounting frame 220. The filtering mechanism includes a first filter net 310 and a second filter net 320. Four first connecting blocks 311 are provided on the first filter net 310, and each first connecting block 311 is movably inserted into one of the first inserting rings 213. Four second connecting blocks 321 are provided on the second filter net 320, and each second connecting block 321 is movably inserted into one of the second inserting rings 223. A first fixing ring 214 and a first inserting pin 215 are provided on the first mounting frame 210, and a second fixing ring 224 and a second inserting pin 225 are provided on the second mounting frame 220. The first inserting pin 215 is movably inserted into the second fixing ring 224, and the second inserting pin 225 is movably inserted into the first fixing ring 214. The fixing mechanism includes two clamping blocks 410 and two springs 420. One end of each spring 420 is arranged on the inner side wall of one of the limiting openings 120, and the other end is connected to one of the clamping blocks 410. The two clamping blocks 410 are connected to the outside.

[0024] That is to say, when installing this filter device for central air conditioners on the ceiling, first align the installation frame 100 with the corresponding installation opening. There are two corresponding card slots in the installation opening. By pushing the two clamping blocks 410, the two springs 420 are compressed. Then place the installation frame 100 into the installation opening. At this time, the connecting plate 500 will abut against the external ceiling. Release the two clamping blocks 410. Under the action of the springs 420, the clamping blocks 410 are pushed, so that each clamping block 410 is clamped in a card slot, that is, the installation of the installation frame 100 is completed. Then insert the four first connecting blocks 311 on the first filter screen 310 into the four first insertion rings 213, and insert the four second connecting blocks 321 on the second filter screen 320 into the four second insertion rings 223 to complete the installation of the first filter screen 310 and the second filter screen 320. Then insert the first insertion block 211 into the first connecting ring 130 and insert the second insertion block 221 into the second connecting ring 140. It is worth mentioning that the shapes of the first insertion block 211 and the second insertion block 221 are both cylindrical, so they can rotate in the first connecting ring 130 or the second connecting ring 140. Further, the insertion direction of the first insertion block 211 is opposite to the insertion direction of the second insertion block 221.

[0025] That is to say, after the first mounting bracket 210 and the second mounting bracket 220 are installed, by rotating the first mounting bracket 210 and the second mounting bracket 220 so that they abut against each other, and then inserting the first pin 215 into the second fixing ring 224 and inserting the second pin 225 into the first fixing ring 214, the first mounting bracket 210 and the second mounting bracket 220 can be fixed, that is, it can be used normally.

[0026] In the above embodiment, when it is necessary to replace the first filter screen 310 or the second filter screen 320, open the first pin 215 and the second pin 225, and then rotate the first mounting bracket 210 or the second mounting bracket 220 so that they no longer abut against each other. That is to say, when rotating until the first mounting bracket 210 and the second mounting bracket 220 are both vertically located below the ceiling, directly push up the first filter screen 310 to take it out, or directly push up the second filter screen 320 to take it out. The overall operation is simple and convenient, which is convenient for the staff to disassemble and install the first filter screen 310 and the second filter screen 320, and the cleaning is simple.

[0027] In summary, the above embodiments are not restrictive embodiments of the present invention. Any modification or equivalent deformation made by those skilled in the art on the basis of the substantial content of the present invention is within the technical scope of the present invention.
