The top plate 1206 is fixedly connected to the top surface of the top pipe 1205. The inclined fin 1204 is in a funnel shape. There are a plurality of inclined fins 1204, and the plurality of inclined fins 1204 are all sleeved on the outer walls of the plurality of support strips 1203. The plurality of inclined fins 1204 are circumferentially evenly distributed along the length direction of the support strip 1203. On the lower end outer wall of the bottom pipe 1201, there is an external thread Ⅰ1202. On the top surface of the lower water tank 9, there is a threaded hole Ⅰ901. The external thread Ⅰ1202 is connected in the threaded hole Ⅰ901. The sponge strip 11 is inserted into the humidifying branch pipe 12. The sponge strip 11 is arranged between the support strips 1203. The lower end of the sponge strip 11 extends into the lower water tank 9. The top end of the sponge strip 11 abuts against the bottom surface of the top plate 1206. There are a plurality of threaded holes Ⅰ901, and the number of the threaded holes Ⅰ901, the number of the sponge strips 11 and the number of the humidifying branch pipes 12 are the same and correspond one by one;Inside the frame 1, there is an upper water tank 10 connected.

[0023] When the utility model is in use, the fan 5 is powered on and rotates to drive the air to flow to achieve ventilation. The filter mesh plate 18 filters the air. The setting of the humidifying assembly humidifies and dust-removes the air passing through the humidifying assembly, thereby humidifying the interior of the green building.

[0024] The sponge strip 11 absorbs water from the lower water tank 9. The humidifying branch pipe 12 plays a supporting role for the sponge strip 11. When the air flows through the plurality of humidifying assemblies, since gaps are formed between the plurality of support strips 1203 of each humidifying branch pipe 12, the air contacts the sponge strip 11 to form a humidifying effect on the air.

[0025] Since the sponge strip 11 has a certain height, there may be a situation where the upper part of the sponge strip 11 cannot be wetted when the sponge strip 11 absorbs water from the lower water tank 9. In order to further improve the humidifying effect in this use information, the upper part of the sponge strip 11 is wetted through the upper water tank 10 and the top water pipe 13. It should be noted that by controlling the valve, the water body in the top water pipe 13 forms a dripping effect, and it is necessary to prevent the water flow in the top water pipe 13 from being too large and leaking.

A cleaning brush 20 is fixedly connected to the rotating shaft of the rotating paddle 19. The cleaning brush 20 is rotatably connected to the filter screen plate 18. Note that for the setting of the rotating paddle 19 and the rotating shaft, the rotating shaft is rotatably connected to the filter screen plate 18, and the rotating paddle 19 is fixedly connected to the rotating shaft, so that the rotating paddle 19 and the rotating shaft rotate together.

[0030] When the fan 5 is energized and rotates to drive the air to flow to achieve ventilation, since the support pipe 2 is a relatively complete cylinder, the air flows through the support pipe 2 to drive the rotating paddle 19 to rotate. The rotation of the rotating paddle 19 drives the cleaning brush 20 to rotate, thereby cleaning the filter screen plate 18.

[0031] Upper struts 3 are fixedly connected between the inner top surface of the frame 1 and the outer wall of the support pipe 2.

There are multiple connecting rods 8, and the multiple connecting rods 8 are circumferentially and evenly distributed with the axis of the support ring 7 as the center. One ends of the multiple connecting rods 8 away from the support ring 7 are all fixedly connected to the inner wall of the support pipe 2. The fan 5 is fixedly connected to the support ring 7.

[0033] The setting of the upper struts 3 and the lower struts 4 mentions the support stability of the frame 1 for the support pipe 2. The left and right sides of the support pipe 2 can be directly welded to the left and right inner walls of the frame 1. The bracket 6 is used for the stable connection of the fan 5.

[0034] When connecting the present utility model to a building, the frame 1 can be directly connected into the holes reserved on the building wall. The frame 1 can be welded and formed by using profiles such as square steel, angle steel, steel plates, etc. according to the actual dimensions.
