Fig. 1 shows the section of structure of the air filtering apparatus of using according to isolator of the present utility model.
Fig. 2 shows the schematic diagram of changing high efficiency particulate air filter in Fig. 1.
Fig. 3 shows the schematic diagram of changing high efficiency particulate air filter in another kind of Fig. 1.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1 shows the section of structure of the air filtering apparatus of using according to isolator of the present utility model.With reference to Fig. 1, the air filtering apparatus 1 that isolator is used comprises cavity 10, chamber lid 11, blower fan 12, the first high efficiency particulate air filter 13 and the first sealing ring 14.Wherein, cavity 10 is cylindrical, and cavity 10 be connected with the top of isolator 2 in.The upper end of cavity 10 is fixed in chamber 11 activities of lid, in order to be covered in better on cavity 10, the cross section of chamber lid 11 is rounded, and in the present embodiment, be provided with buckle 111 on the outer peripheral edges of chamber lid 11, be provided with the first groove (not indicating) in the upper end of cavity 10, buckle 111 is corresponding with the first groove, to realize that chamber lid 11 is fixed in the upper end of cavity 10, can also cover in the chamber in addition and be provided with the second groove 112 on 11 in buckle 111 insertion the first grooves, open to facilitate chamber lid 11.Blower fan 12 is connected with the sidewall of cavity 10, is used for blowing and air draft for isolator 2.The first high efficiency particulate air filter 13 is arranged in cavity 10, and between blower fan 12 and isolator 2, the first high efficiency particulate air filter 13 is cylindrical to match with cavity 10.The first sealing ring 14 is embedded on the inwall of cavity 10, and between the inwall of the first high efficiency particulate air filter 13 and cavity 10, the first sealing ring 14 is sealed in the first high efficiency particulate air filter 13 in cavity 10.For the air that enters from microblogging is better filtered, the air filtering apparatus 1 that isolator is used can also comprise the second high efficiency particulate air filter 15 and the second sealing ring 16.Wherein, the second high efficiency particulate air filter 15 is arranged in cavity 10, and is positioned at the below of the first high efficiency particulate air filter 13.The second sealing ring 16 also is embedded on the inwall of cavity 10 and between the inwall of the second high efficiency particulate air filter 15 and cavity 10, is used for the second high efficiency particulate air filter 15 is sealed in cavity 10.
