Referring to Fig. 4, optionally, the medial surface of the first end 110 is provided with guiding surface 112, air inlet in the present embodiment
The gas entered at mouthfuls 111 is flowed along guiding surface 112, can Rapid contact to filter layer, purification efficiency is higher.Guiding is oblique
Face 112 can be continuous cambered surface, and further, guiding surface 112 defines circular conical surface, guiding surface 112 have close into
The first edge of port 111, guiding surface 112 have the second edge far from air inlet 111, and first edge surrounds circle, the
Two edges surround circle, and the internal diameter of guiding surface 112 is gradually increased along wherein axis direction from first edge to second edge, from
The smog that air inlet 111 enters is flowed along guiding surface 112, can quickly be spread and be flowed at filter layer, and purification is improved
Efficiency.
In other embodiments, guiding surface 112 can be isosceles trapezoid face, and there are four the settings of guiding surface 112, and four
Guiding surface 112 is sequentially connected end to end, and the upper bottom of four guiding surfaces 112 surrounds the first opening, under four guiding surfaces 112
Bottom surrounds the second opening, the first open communication air inlet 111, the bore that the bore of the first opening is open less than second.Guiding is oblique
The structure in face 112 designs, and the smog that equally may be implemented to enter in filter housing 100 is diffused rapidly on filter layer, with mistake
Filtering layer comes into full contact with, and enhances clean-up effect.
It should be appreciated that the structure of the second end 130 can be similar with the structure of the first end 110, the second end 130 is used for
Filtered gas is put together and is discharged from exhaust outlet 131, the efficiency of gas discharge is improved.
It should be noted that filter layer is mounted in middle housing 120, for the ease of the installation of filter layer, in middle section shell
Clamping protrusion is provided on the inner wall of body 120, adjacent clamping has convexed to form clamping groove, and filter layer is connected in clamping groove.
Referring to Fig. 5, filter layer includes the bacteriolyze enzyme layer 200 for stacking gradually arrangement, ULPA film layer in the present embodiment
300, active carbon layer 400, cold catalyst layer 500 and anion layer 600, bacteriolyze enzyme layer 200, ULPA film layer 300, active carbon layer
400, cold catalyst layer 500 and anion layer 600 are mounted in gas flow channel, and bacteriolyze enzyme layer 200 is set close to air inlet 111
It sets, anion layer 600 is arranged close to exhaust outlet 131.
It should be appreciated that filter layer is cylindrical structure when the chamber that middle housing 120 surrounds is cylindrical cavity；When
When the chamber that middle housing 120 surrounds is square column type cavity, filter layer is square body structure.Filter layer and middle housing 120
Close structure, the good airproof performance between filter layer and the inner wall of middle housing 120.
In other embodiments, air inlet pipe fitting 140 is installed at air inlet 111, exhaust pipe is installed at exhaust outlet 131
Connector 150.
It is spread since filter will cause bacterium and be enriched in filter, it is provided with bacteriolyze enzyme layer 200 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 loose 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 200 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 200, 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 300 is provided with after bacteriolyze enzyme layer 200, the full name in English of ULPA film layer 300 is
UltraLowPenetrationAirFilter, Chinese are ultra high efficiency air filter or ultralow penetrance air filtration
Device reaches 99.999% or more to the filter efficiency of the dust particles such as 0.1-0.2 μm of particle, smog and microorganism.ULPA film
Layer 300 i.e. ultra high efficiency air filtration film layer or ultralow penetrance air filtration film layer, can not only adsorb a variety of particles, may be used also
To remove the peculiar smell in smoke removing, then poisonous and hazardous polar molecule in adsorbing smoke again purifies air with solid base,
Virion is killed, pollute the ingredient in smog will not to equipment inside.
Activated carbon layer adsorbs polar molecule or nonpolar molecule.It is stupid such as NH3, formaldehyde.
Cold catalyst layer 500 mainly carries out oxidation reaction to inorganic harmful substance, generates harmless carbon dioxide and water.
Anion layer 600 can occur electrically to neutralize and settle absorption with the macromolecular in smog, while Electrostatic Absorption arrives
Flue dust, bacterium, virus surface settle it and make bacteria inactivation.
Operation cigarette smoking system filter provided in this embodiment comprising have filter housing 100 and filter layer, filter
Device shell 100 is internally provided with chamber, and for installing filter layer, and the lid on filter housing can be opened, and is convenient on demand more
Filter layer is changed, cost is greatly reduced.Air inlet 111 and exhaust outlet 131,111 He of air inlet are provided on filter housing 100
131 connecting chamber of exhaust outlet, forms gas flow channel between air inlet 111 and exhaust outlet 131.Filter layer includes successively setting
Bacteriolyze enzyme layer 200, ULPA film layer 300, active carbon layer 400, cold catalyst layer 500 and the anion layer 600 set, filter layer installation
In flow channel, bacteriolyze enzyme layer 200 is arranged close to 111 one end of air inlet, and anion layer 600 is set close to 131 one end of exhaust outlet
It sets.Filter layer obstructs in gas flow channel, and the gas entered from air inlet 111 passes sequentially through bacteriolyze enzyme layer 200, ULPA film
Then layer 300, active carbon layer 400, cold catalyst layer 500 and anion layer 600 are discharged from exhaust outlet 131.In surgical procedure,
Smog enters from air inlet 111, is absorbed by the harmful substance in smog when filter layer, and smog is after purification from exhaust outlet
During 131 discharges, good purification, the gas of discharge are not easy to influence operating room environment, and smog passes through filter layer, smog
In harmful substance pass through multiple filtration, contact of the harmful substance in smog with filter layer is abundant, and the clarification time is long, nuisance
Matter can be not easy remaining bacteria in filter by quick inactivating, be not easy to become pollution sources.
