Difficulty on meter be present.
Utility model content
The utility model purpose is to be to provide a kind of dust cover with air filtering function, to solve above-mentioned at least one
Individual technical problem.
The utility model solves the problems, such as to realize using following technical scheme：
Dust cover with air filtering function, including dust cover, it is characterised in that be provided with an air-flow in the dust cover
Passage, the gas channel include an inlet end and an outlet side being connected with the air inlet of air conditioning wind pipe, the gas channel
Inwall adhesion have filter layer made of glass fibre, the gas channel is sequentially provided with first made of magnet along water conservancy diversion direction
Second wire netting made of wire netting, steel wool；
The filter layer is provided with the first annular ditch groove for being used for placing the first wire netting, and the filter layer, which is provided with, to be used for
The second annular ditch groove of the second wire netting is placed, in the central axis of first annular ditch groove, second annular ditch groove
Central axis of the mandrel line with the gas channel overlaps；
The water conservancy diversion direction of the gas channel is from top to bottom, the wall thickness of the dust cover successively decreases successively from top to bottom.
The utility model realizes by setting dust cover on air conditioning wind pipe, and by the gas channel in dust cover
Filtering to air conditioning wind pipe air intake, impurity can be reduced and enter air conditioning wind pipe, influence the normal use of air conditioning wind pipe.This practicality is new
Type and can absorb certain metallic particles by the first wire netting, and the utility model can absorb sky by the fine hair on steel wool
Dust in gas.Filter layer on inwall can play further filtering, and the annular ditch groove on filter layer can make metal
The placement of net is more firm.The utility model is because filtered air can be to air inlet by the wall thickness gradual change of dust cover
Certain abrasion is caused at end, and the service life of dust cover can be extended by improving the thickness of inlet end.
Both less air flow resistance is considered, in turn ensure that filter effect.
First wire netting is vertical with the water conservancy diversion direction of the gas channel, the second wire netting and the gas channel
Water conservancy diversion direction is vertical.Can preferably it play a role in filtering.
Spacing between first wire netting and second wire netting is in 1~3cm.
The utility model can make filtering more abundant by limiting spacing.
Junction, second annular ditch groove and second gold medal of first annular ditch groove and first wire netting
The junction of category net is equipped with packed layer made of diatom ooze.
The utility model can reduce the space of junction by diatom ooze, make connection even closer, and diatom ooze is certainly
Body also there is suction-operated can purify air.
The thickness of the filter layer is equal in 1~1.5cm, first annular ditch groove, the depth of second annular ditch groove
For 0.5cm.The depth that the utility model limits annular ditch groove both ensure that bonding strength with wire netting, in turn ensure that filtering
The working effect of layer.
The filter layer is provided with bar-shaped projection, and the bar-shaped projection is located at the inlet end and first annular ditch groove
Between, the bar-shaped raised height is the 1/3~1/2 of the gas channel internal diameter.
Flow-disturbing is produced with bar-shaped projection contacts when the utility model can admit air into by bar-shaped projection, improves sky
Gas passes through the filter effect of gas channel.
Brief description of the drawings
Fig. 1 is part-structure sectional view of the present utility model.
Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
Referring to Fig. 1, the dust cover with air filtering function, including dust cover 1, dust cover is interior to be provided with a gas channel 2,
Gas channel, which includes an inlet end 4 and an outlet side 5 being connected with the air inlet of air conditioning wind pipe, the inwall adhesion of gas channel, to be had
Filter layer 3 made of glass fibre, gas channel are sequentially provided with the first wire netting 6, steel wool made of magnet along water conservancy diversion direction
Manufactured second wire netting 7；Filter layer is provided with the first annular ditch groove 8 for being used for placing the first wire netting, and filter layer is provided with
For placing the second annular ditch groove 9 of the second wire netting, the central axis of the first annular ditch groove, the central shaft of the second annular ditch groove
Line overlaps with the central axis of gas channel；The water conservancy diversion direction of gas channel is from top to bottom, the wall thickness of dust cover is from up to
Under successively decrease successively.The utility model passes through the gas channel reality in dust cover by setting dust cover on air conditioning wind pipe
The filtering to air conditioning wind pipe air intake is showed, impurity can be reduced and enter air conditioning wind pipe, influence the normal use of air conditioning wind pipe.This reality
Certain metallic particles and can be absorbed by the first wire netting with new, the utility model can be inhaled by the fine hair on steel wool
Receive the dust in air.Filter layer on inwall can play further filtering, and the annular ditch groove on filter layer can make
The placement of wire netting is more firm.The utility model is because filtered air can be right by the wall thickness gradual change of dust cover
