Specifically, filter assemblies 100, using origin as starting point, the X-axis along the first plane is successively fixed with filter layer, UV lamp
102, active carbon layer 104 and shell 105；
Active carbon major function is the odor particles in adsorption gas flow, removal odoring substance etc..The main function of filter layer
It is particulate matter, bacterium, virus, dust and the grease etc. in oil smoke air-flow.
The installation site of active carbon layer after filter layer, such purpose be allow bulky grain particle or grease in early period
It is first removed or stops in filter layer, it is ensured that the hole of activated carbon surface is not attached or filled by grease, extends active carbon
Service life.
Simultaneously again because not only being sterilized to the soot gas of air outlet, while also can under the irradiation of UV lamp
Sooty substance, the odor particles adsorbed in active carbon are sterilized, active carbon is kept to be able to maintain activity always.
Filter assemblies 100 are disposed with filter cotton 106, first baffle 107, edge using origin as starting point, along Y-axis positive direction
Y-axis negative direction is provided with second baffle 108.

Specifically, gauze 101 is provided with venthole, it is logical that venthole is set as polygon venthole, rectangle venthole, circle
Any one or more in stomata or elliptical vent hole；
Specifically, the area of venthole is SHole；1mm2≤SHole≤2500mm2；
Specifically, between shell 105 and the first plane along X-axis relative to distance be DShell；500mm≤DShell≤1500mm。
Specifically, active carbon layer 104 is relative to X-axis with a thickness of HCharcoal；5mm≤HCharcoal≤200mm。
Filter cotton 106 is relative to Y-axis with a thickness of HCotton；5mm≤HCotton≤80mm。
Specifically, filter cotton 106 is set as in G1 cotton, G2 cotton, G3 cotton, G4 cotton, F5 cotton, F6 cotton, F7 cotton or F8 cotton any
It is one or more；Specifically, UV lamp 102 is set as ultraviolet sterilization UV lamp 102；The wavelength of ultraviolet sterilization UV lamp 102 is
β, 200nm≤β≤300nm.
Filter cotton 106 is set as G3 cotton in the present embodiment.
Specifically, shell 105 is provided with multiple air outlets.
In the process of actual use, filter cotton, first baffle, second baffle and shell can by using clamping or
It is threadedly coupled any one mode or various ways connection in flexible strand connection or iron wire connection, specific connection type is according to reality
The environment self-changeable that border uses, the common knowledge based on one of ordinary skilled in the art, specific connection type is just not
It repeats again.
When in use, the gas of the air outlet discharge of smoke machine works as oil smoke by setting C for filter cotton and the first plane
Exclusion gas when excluding because the airflow direction for excluding gas flows through filter cotton, filter cotton is simultaneously to the cooking fume of a part
Body also functions to the effect gathered.Filter cotton is flowed directly into, by the mistake of filter cotton because of air flow direction again simultaneously
Filter, the gas of smoke machine mainly carries out the clean air of discharge from the distance A along Y direction, when the air outlet of kitchen ventilator
When air flow direction filter cotton, because the X-axis two sides of the first plane also there are gap, allow the air-flow of smoke machine oil smoke from first
The two sides of the X-axis of plane are discharged and slow down the excessive pressure of release oil smoke air-flow, so that the pressure of oil smoke air-flow is to filtering
Cotton does not damage, and achievees the effect that no crushing, while playing the role of protecting this filtration system again.First baffle will pass through
Filter cotton flows to filter layer, UV lamp, the active carbon layer of X-axis from the region of range A into the soot gas after preliminary purification excessively again,
The repeated filtration of the another step of a step is carried out by layering simultaneously and absorbs the particulate matter and gas with foreign flavor in oil smoke
Substance, second baffle is by preventing untreated soot gas from revealing from the air outlet of kitchen ventilator.
Circulating smoke machine filter screen for space environment in indoor and outdoor of the invention, can to the exclusion gas in smoke machine
It is sufficiently filtered, so that the discharge gas of smoke machine reaches complete cleaning, with simple, the easy to use feature of structure, largely
Save manpower, material resources and financial resources.
Embodiment 2.
