Limitation.
The state of the engineering truck air-conditioning air intake filter that Fig. 1 is provided for the utility model embodiment in actual applications
Figure, Fig. 2 is the sectional view of the first filter, and Fig. 3 is the structural representation of the second filter.
Referring to Fig. 1 to Fig. 3, the utility model embodiment provides a kind of engineering truck air-conditioning air intake filter,
Including：Support 200, the first filter 300 and the second filter 400；Its medium-height trestle 200 is fixedly installed on air blower
On 100, outer circulation air inlet 210 is provided with support 200；First filter 300 is fixedly installed on support 200, and first
Air inlet 330, gas outlet 340, oil sump 320 and screen pack 310 are provided with filter 300, screen pack 310 is positioned close to
On the position of gas outlet 340, gas outlet 340 is corresponding with the position of outer circulation air inlet 210, is kept between screen pack 310 and oil sump 320
There is distance, distance is maintained between air inlet 330 and screen pack 310；Second filter 400 be fixedly installed on air blower 100 with
Between interior circulation air inlet 220.
The engineering truck air-conditioning air intake filter that the utility model embodiment is provided is in its actual application, Ke Yitong
Cross support 200 to be fixed on the airintake direction of air blower 100, by the effect of air blower 100, ambient atmos can be sequentially passed through
First filter 300 and the second filter 400, are converted into the air of cleaning.Specifically, when ambient atmos pass through the first mistake
Filter during device 300, gas can enter from the air inlet 330 of the first filter 300, due to by screen pack 310
Stop, the gas outlet 340 that gas can not be directly from the first filter 300 is discharged, and be only capable of flowing to the direction of oil sump 320；When
After gas is contacted with the fluid in oil sump 320, larger particles can be sticked in fluid in gas, so as to complete first time mistake
Filter；After first time filters, gas enters in screen pack 310 and flowed to gas outlet 340, by the effect of air blower 100, one
The gas that part carries impurity can be blown back into oil sump 320, and impurity can produce mist of oil after being hit with fluid, and mist of oil enters with air-flow
Enter and stick on screen pack 310, when gas flows in screen pack 310, the impurity in gas can be further adhered to
Fluid absorption on screen pack 310, it is achieved thereby that second of filtering to gas, meanwhile, as mist of oil is constantly in screen pack
Accumulated on 310, gradually form oil droplet, oil sump 320 is finally dripped back into by Action of Gravity Field, so as to also achieve the circulation profit of fluid
With.And the gas flowed out from the gas outlet 340 of the first filter 300 can enter the second filter 400 and carry out third time mistake
Filter, to filter the molecule remained in gas, so as to reach the purpose of thoroughly filtering gas.
Constituted it should be noted that screen pack 310 can be interlocked by wire, with realize its with mist of oil and gas it is abundant
Contact, the adhesion of increase fluid and filter area；The side wall of screen pack 310 is closed body, and side wall and the first filter 300
On air inlet 330 it is relative, so as to so that the gas entered by the air inlet 330 of the first filter 300 is by screen pack
310 stop and change flow direction, gas is first passed through fluid, to realize the filtering to larger particles.
Further, interior circulation air inlet 220, air door 500 and connecting rod 510 are provided with support 200, air door 500 passes through
Connecting rod 510 is swung between interior circulation air inlet 220 and outer circulation air inlet 210；Specifically, when starting outer circulation pattern,
Air door 500 is rotated by connecting rod 510 and closes interior circulation air inlet 220, and ambient atmos can sequentially pass through the first filtering dress
Put 300 and second filter 400 realize all three times filtering；When starting interior circulation pattern, air door 500 is to outer circulation air inlet
Mouth is swung at 210 positions, and outer circulation air inlet 210 is closed, and now, gas can enter merely through the second filter 400
Row circulating filtration.It should be noted that the gas circulated under interior circulation pattern is the gas in car steering room, relative to outer
Boundary's gas, it has higher cleannes, therefore filters molecule merely through the second filter 400.
Further, as shown in figure 3, the second filter 400 includes filter core 410 and housing 420, filter core 410 passes through shell
Body 420 is fixedly installed on air blower 100.
It is understood that for the ease of the dismounting of the second filter 400, buckle can be provided with housing 420
421, housing 420 is connected and fixed by buckle 421 with air blower 100.
Further, relative to nylon or gauze, glass fibre has preferable filter effect for tiny particles content,
Therefore the material of filter core 410 can be glass fibre.
Further, as shown in figure 1, into obtuse angle between the second filter 400 and gas flow, gas is passing through the second mistake
When filtering device 400, gas can fully be contacted with glass fibre, without being passed through from the gap between glass fibre, so as to realize
Abundant filtering to finely ground particles in gas.
Further, in order to prevent the ambient atmos containing a large amount of impurity in the situation without the first filter 300
Lower entrance outer circulation air inlet 210, the engineering truck air-conditioning air intake filter that the utility model embodiment is provided can also include
Sealing ring, the sealing ring is fixedly installed between the filter 300 of outer circulation air inlet 210 and first.
The engineering truck air-conditioning air intake filter that the utility model embodiment is provided, by setting the first filter and the
Two filters, realize the thorough filtering to impurity particle in gas, while by setting air door, realizing outer circulation pattern
With the switching of interior circulation pattern, it is ensured that the efficiency and quality of gas filtration.
The utility model embodiment additionally provides a kind of air-conditioning system, including air blower 100, wherein, the air-conditioning system is also
The engineering truck air-conditioning air intake filter provided including the utility model any embodiment, the engineering truck air-conditioning air intake filter
It is fixedly installed on by support 200 on air blower 100.
