It should be appreciated that filter layer is cylindrical structure when the chamber that middle housing 214 surrounds is cylindrical cavity；When When the chamber that middle housing 214 surrounds is square column type cavity, filter layer is square body structure.Filter layer and middle housing 214 Close structure, the good airproof performance between filter layer and the inner wall of middle housing 214.

In other embodiments, inlet suction port 217 is installed at import 212, exhaust fitting is installed at outlet 216 218。

It is spread since filter will cause bacterium and be enriched in filter, it is provided with bacteriolyze enzyme layer 220 in the filter (lysozyme is a kind of hydrolase for being acting exclusively on microorganism wall, claims packet muramidase or the hydrolysis of N acetyl murein glycan Enzyme, it exclusively acts on β 1,4 keys in peptide polysaccharide molecule between N acetylmuramic acid and N acetylglucosamine, thus broken The cell wall of bad bacterium is allowed to relaxation and loses the protective effect to cell, finally makes bacterolysis dead), and have changed Adsorption layer of the original based on active carbon is adsorbed using the stronger material of adsorption capacity.Bacteriolyze enzyme layer 220 is located at the first floor, band Encounter first of the filter that germy smog has arrived cigarette smoking system is exactly bacteriolyze enzyme layer 220, after so that bacterium is come in just Activity is lost, filter is made not become a pollution sources again in the long-term use.

ULPA film layer 230 is provided with after bacteriolyze enzyme layer 220, the full name in English of ULPA film layer 230 is Ultra Low Penetration Air Filter, Chinese be ultra high efficiency air filter or ultralow penetrance air filter, it is right The filter efficiency of the dust particles such as 0.1-0.2 μm of particle, smog and microorganism reaches 99.999% or more.ULPA film layer 230 That is ultra high efficiency air filtration film layer or ultralow penetrance air filtration film layer, can not only adsorb a variety of particles, can also go Peculiar smell in smoke removing, poisonous and hazardous polar molecule in adsorbing smoke, then again purifies air with solid base, kills Virion pollute the ingredient in smog will not to equipment inside.Active carbon layer adsorbs polar molecule or nonpolarity point Son.It is stupid such as NH3, formaldehyde.Cold catalyst layer 250 mainly carries out oxidation reaction to inorganic harmful substance, generates harmless titanium dioxide Carbon and water.Anion layer 260 can occur electrically neutralize and settle absorption with the macromolecular in smog, while Electrostatic Absorption is to cigarette Dirt, bacterium, virus surface settle it and make bacteria inactivation.

Filter assemblies provided in this embodiment comprising have shell 210 and filter layer, shell 210 is internally provided with Chamber is provided with import 212 and outlet 216, import 212 and 216 connecting chambers of outlet for installation filter layer on shell 210, into Gas flow channel is formd between mouth 212 and outlet 216.Filter layer includes the bacteriolyze enzyme layer 220 set gradually, ULPA film layer 230, active carbon layer 240, cold catalyst layer 250 and anion layer 260, filter layer is mounted in flow channel, bacteriolyze enzyme layer 220 It is arranged close to 212 one end of import, anion layer 260 is close to the setting of 216 one end of outlet.Filter layer is obstructed in gas flow channel In, the gas entered from import 212 passes sequentially through bacteriolyze enzyme layer 220, ULPA film layer 230, active carbon layer 240, cold catalyst layer 250 and anion layer 260, then it is discharged from outlet 216.In surgical procedure, smog enters from import 212, by filter layer When smog in harmful substance be absorbed, smog by purification after from outlet 216 be discharged, good purification, the gas of discharge is not Easily influence operating room environment, and smog is by during filter layer, the harmful substance in smog passes through multiple filtration, in smog Contact of the harmful substance with filter layer it is abundant, the clarification time is long, and harmful substance can be not easy residual by quick inactivating in filter Bacterium is stayed, is not easy to become pollution sources.

It should be noted that the full name in English of ULPA film layer 230 is Ultra Low Penetration Air Filter, Chinese be ultra high efficiency air filter or ultralow penetrance air filter, to 0.1-0.2 μm of particle, smog and The filter efficiency of the dust particles such as microorganism reaches 99.999% or more.ULPA film layer 230 be ultra high efficiency air filtration film layer or The ultralow penetrance air filtration film layer of person, can not only adsorb a variety of particles, can also remove the peculiar smell in smoke removing, adsorbing smoke In poisonous and hazardous polar molecule, then air is purified with solid base again, kill virion, make the ingredient in smog Equipment inside will not be polluted.

Please refer to Fig. 9-Figure 12, in the present embodiment, fan assembly 300 includes shell 310, connector 320 and blower Main body 330.Fan main body 330 is mounted in shell 310 by connector 320.Between fan main body 330 and the inner wall of shell 310 Every setting.In this way, the vibration generated in 330 course of work of fan main body is not easy to be transmitted on shell 310, also it is not easy to be transmitted to whole In a system, noise is reduced, improves surgical environments.

In the present embodiment, shell 310 is enclosed construction, and shell 310 has storage room 311, third opening 312 and the 4th Opening 313, third opening 312 and the 4th opening 313 are located on the wall of shell 310, third opening 312 and the 4th opening 313 Shape is arranged on demand, herein without specifically limiting.Third opening 312 is connected to storage room 311 with the 4th opening 313. In use, smog is introduced fan main body 330 from third opening 312 for connecting with pipeline by third opening 312 In, and smog is discharged the work of fan main body 330 from the 4th opening 313.

Optionally, shell 310 can be cube shape structure, such as can be rectangular parallelepiped structure or cube structure, with The structure matching of fan main body 330, so that overall structure is more compact, the space occupied is small, saves space resources.

In the present embodiment, shell 310 is illustrated by taking cuboid structure as an example.Shell 310 includes rectangular-shaped Front side board, back side panel, left plate, right side plate, top plate and bottom plate, front side board, left plate, back side panel, back side panel successively connect from beginning to end It connects, for mounting of roof plate at the top of front side board, left plate, back side panel, back side panel, bottom plate is mounted on front side board, left plate, rear side The bottom of plate, back side panel.Further, front side board, back side panel, left plate, right side plate and top plate constitute open at one end, one section Closed box body, base plate cover are located on box body, close opening, and bottom plate is detachably connected with box body, such structure design, Convenient for fan main body 330 to be mounted in shell 310, it is also convenient for the disassembly and maintenance of fan main body 330.
