the labyrinth type water flowing groove 1 is arranged on the air filter shell 3, the labyrinth type water flowing groove 1 is composed of a water flowing groove shell 11 and grid type reinforcing ribs 12 which are arranged on the water flowing groove shell 11 in a transverse and longitudinal staggered mode, wherein part of the grid type reinforcing ribs 12 are provided with openings 13, so that water flow can flow down along the openings 13 along the fall direction, in a specific implementation scheme, a flow channel formed by the flow direction of the water flow guided by each opening 13 is a labyrinth type line and is not in a conventional straight line or spiral line flow direction, so that on one hand, condensed water on the air filter shell 3 is fully collected and guided, on the other hand, dust, fine sand and the like mixed in the water are further deposited at the turning position of the water flow, the filtering effect of a related structure is further enhanced, and the water outlet is prevented from being blocked by related sundries.
In a preferred embodiment, the drainage structure is provided with an impoundment area 28, and when the height of the accumulated water in the impoundment area 28 exceeds a certain value, the accumulated water in the impoundment area 28 is drained by gravity. In a specific embodiment, the height of the water accumulation in the impounded area 28 is determined by the vertical height difference between the bottom of the drainage structure body and the bottom of the upper through hole 24 on the drainage structure body 2. The accumulated water discharge port of the scheme of the invention is provided with the sound absorption cotton 26, the sound absorption cotton 26 is made of glass fiber, and the sound absorption cotton 26 can play a role in noise reduction and simultaneously does not influence the discharge of accumulated water in the water storage area 28.
Based on this application technical scheme structure that figure 1 shows, because water outwards discharges after inhaling the sound cotton, under the normal condition, inhale the discharge velocity that the sound cotton can influence water, nevertheless, ponding discharge hysteresis can not appear in this application technical scheme, can also realize the quick discharge of ponding simultaneously, the reason is as follows:
1. because the rivers passageway setting of empty filter casing area labyrinth, flowing water can reach to be located the lowest drainage structures body department through a longer time and passageway, and block to store in this drainage structures bottom by inhaling the sound cotton, make a water storage area (like figure 1) appear in the drainage structures, after the difference in height h that the water storage height surpassed water storage area bottom and upper portion through-hole among the drainage structures, ponding can be under the action of gravity, flow into columnar body middle part smoothly through the upper portion through-hole, and finally discharge through the wash port.
2. Through above-mentioned structural design, can reduce the volume that is used for structures such as filtration, dust removal for this drainage structures diameter is bigger than current drainage structures, and the drainage is more unobstructed.
3. The cotton principal ingredients of sound absorption that uses in this application is glass fiber, does not absorb water, has avoided the change of inhaling the sound effect on the one hand, and on the other hand can realize blockking the effect of ponding.
4. The degree of compaction of the glass fiber stack can be adjusted.
5. The air filter is vibrated, and accumulated water can be smoothly discharged under vibration.
According to the technical scheme, the drainage structure is provided with the multi-layer filter, so that the cleanness of the holes can be effectively kept. In addition, the drain hole is provided with silencing cotton, so that noise radiation can be effectively prevented; the drainage structure is an independent sub-part and is combined with the body in a clamping way, so that the process difficulty of the body is not increased; the drainage structure does not relate to a gas flow field in the engine room, the drainage principle is reliable, and functional failure cannot be caused. The drainage structure of the invention utilizes a multi-layer filtering structure to separate mud and water, and the filtered water is discharged through the noise reduction pipe internally provided with the sound absorption cotton. Greatly reduced is from the noise of drain hole department radiation, simultaneously because of the multilayer filters back, the dust can obviously not accumulate to falling the pipe of making an uproar, falls the pipe life of making an uproar and far lengthens by a wide margin.
