Detailed Description

The invention will be further elucidated and described with reference to the following embodiments and drawings in which:

referring to fig. 1 and 2, a clean room fan filtering mechanism includes a housing 10, a fan 20 and a filtering component, wherein the top and the bottom of the housing 10 are respectively provided with a first air inlet 11 and an air outlet 12, and the fan 20 is disposed at the air outlet 12.

The filter assembly comprises a coarse filter composite net 31 and a fine filter composite net 32, the coarse filter composite net 31 is arranged at the first air inlet 11, the fine filter composite net 32 is arranged above the fan 20, the second air inlet 13 is formed in the side face of the shell 10, the second air inlet 13 is positioned between the coarse filter composite net 31 and the fine filter composite net 32, the second air inlet 13 is far away from one side of the inside of the shell 10 and is provided with an air return pipeline 14, and the air return pipeline 14 is communicated with an air return inlet of the clean room.

The first air inlet 11 at the top of the housing 10 is communicated with the outside, and the air outlet 12 at the bottom of the housing 10 is communicated with the inside of the clean room. In the inside fan 20 of casing 10 with outside air from first air intake 11 suction to casing 10, the air that gets into casing 10 carries out prefilter through the coarse filtration composite net 31 of first air intake 11 department earlier, carries out the separation to great impurity in the air, avoids entering into in the casing 10.

The inside air of casing 10 enters into discharges in the clean room from air outlet 12 under fan 20's effect to earlier through fine filtration composite mesh 32 before air outlet 12 discharges, filter dust, bacterium etc. in the air, play further filterable effect, finally discharge the clean room with external air through filtering.

Meanwhile, the second air inlet 13 on the side of the housing 10 is communicated with the return air inlet of the clean room through the return air duct 14, and under the action of the fan 20, air in the clean room is sucked into the return air duct 14 and then enters the housing 10 through the second air inlet 13 to be mixed with air entering from the outside, and the air is filtered and purified through the fine filtering composite net 32 and then is discharged into the clean room again, so that air circulation in the clean room is realized.

Through the structure, the air exhausted from the air return port of the clean room and the outside air can be simultaneously filtered and treated, and then the air is discharged into the clean room, and only one filtering mechanism is adopted to realize the filtering treatment.

In the above scheme, the number of the second air inlets 13 is at least one, and the second air inlets 13 are circumferentially arranged on the side surface of the housing 10.
