In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 shows the section of structure of the air filtering apparatus of using according to isolator of the present invention.
Fig. 2 shows the schematic diagram of changing high efficiency particulate air filter among Fig. 1.
Fig. 3 shows the schematic diagram of changing high efficiency particulate air filter among another kind of Fig. 1.
The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
Fig. 1 shows the section of structure of the air filtering apparatus of using according to isolator of the present invention.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 the cavity 10, the cross section of chamber lid 11 is rounded, and in the present embodiment, be provided with buckle 111 in the outer peripheral edges of chamber lid 11, be provided with the first groove (indicating) in the upper end of cavity 10, buckle 111 is corresponding with the first groove, buckle 111 inserts the upper end of being fixed in cavity 10 in the first groove with realization chamber lid 11, can also cover in the chamber in addition 11 and be provided with the second groove 112, opens to make things convenient for 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 the cavity 10, and between blower fan 12 and isolator 2, and 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 the 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 the 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 the cavity 10.
Under the effect of blower fan 12, enter to the air in the cavity 10 from the outside, because the sealing function of the first sealing ring 14 and the second sealing ring 16, through the filtration of the first high efficiency particulate air filter 13 and the second high efficiency particulate air filter 15, enter in the isolator 2, promoted the air quality that enters in the isolator 2.Same under the effect of blower fan 12, enter the air in the cavity 10 in the isolator 2, also can be expelled in the environment through the filtration of the first high efficiency particulate air filter 13 and the second high efficiency particulate air filter 15, reduced the pollution to environment.
Fig. 2 and Fig. 3 show the schematic diagram of changing high efficiency particulate air filter among Fig. 1.With reference to Fig. 2, when isolator 2 is moving, in the time of need to changing the second high efficiency particulate air filter 15, can open first chamber lid 11, ready new third high effect filter 17 is put into cavity 10 and down pushing, with reference to Fig. 3, the first high efficiency particulate air filter 13 and the second high efficiency particulate air filter 15 move down, until the second high efficiency particulate air filter 15 be urged fall in the isolator 2 till, then chamber lid 11 is covered again, so far, the second high efficiency particulate air filter 15 is changed complete.In this process, high efficiency particulate air filter always with the inner wall sealing of cavity 10, the air that therefore enters from the outside all can be through filtering and entering isolator 2, the internal environment of isolator 2 is not polluted, and has realized the online replacing of high efficiency particulate air filter.
Advantage of the present invention is: high efficiency particulate air filter is set to cylindrical, has simplified installation steps, when high efficiency particulate air filter need to be changed, can change online, avoids destroying when changing high efficiency particulate air filter the gnotobasis of isolator inwall.
Above demonstration and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
