The U-shaped guide plate 36 has the function of water condensation and also has the function of gas flow guide, moisture gas or gas carrying moisture can be subjected to water vapor condensation and gas flow guide, the condensed moisture can flow along the plate surface of the U-shaped guide plate 36, the gas is discharged from the gas outlet through the guide of the plate surface, the function of guiding the gas flow is realized while the water condensation and drainage effects are realized, the gas inlet resistance of an engine can be reduced, the driving dynamic performance of the whole vehicle is enhanced, and the fuel is saved.

Alternatively, the first drainage structure 33 includes a plurality of first drainage holes, and the shape of the first drainage holes may be a circle, an ellipse, a rectangle, or other polygonal structures.

It should be noted that the hole area of the first drainage hole is larger than the hole area of the second drainage structure 34, so as to avoid the accumulation of water at the bottom of the U-shaped guide plate 36 and ensure that the water is smoothly discharged from the U-shaped guide plate 36 to the second drainage structure.

In some embodiments, as shown in fig. 1, the first drainage structure 33 and the second drainage structure 34 are arranged in a vertically offset manner. That is, the second drainage structure 34 located at the lowest point of the air outlet end 3 is far away from the air outlet 37 of the wading throat body 1, and as can be seen from fig. 2, the lowest point of the air outlet end 3 has a certain space, so that the risk of drainage from the air outlet 37 when the water accumulation amount is large can be further avoided.

As an alternative embodiment, as shown in fig. 2, the diversion structure further includes a dividing diversion plate 38, the dividing diversion plate 38 is disposed along the diameter direction of the air outlet 37 and perpendicular to the air outlet 37, the dividing diversion plate 38 divides the bottom of the U-shaped diversion plate 36 into two diversion cavities, and the bottoms of the two diversion cavities are respectively provided with the first drainage structures 33. Specifically, a plurality of first drainage holes are respectively arranged at the lowest points of the two diversion cavities and used as first-layer drainage; the second drainage structure 34 at the bottom of the air outlet end is used as a second layer for drainage, and two-stage drainage is adopted, so that air flow is guided while drainage is smooth, air inlet resistance is reduced, normal use of an engine and an air filter is guaranteed, and the effects of energy conservation and consumption reduction are achieved.

The working principle of the embodiment is as follows: when water enters the pipeline from the air inlet 21 of the wading throat body 1, the water forms a vortex along the bottom of the U-shaped guide plate 36 along two paths of the bottom of the U-shaped guide plate 36 along with the airflow, collides on the boundary guide plate 38, is discharged downwards from the first drainage hole of the U-shaped guide plate, flows to the second drainage structure 34 along the inner wall of the air outlet end 3, and is discharged from the second drainage structure 34.

The present embodiment also prevents the risk of water suck-back into the air filter and the engine by a two-stage water discharge design.

In order to improve the connection strength of the boundary baffle 38, in some embodiments, as shown in fig. 1, 2 and 4, the boundary baffle 38 has a step structure (the step structure is not labeled in the figure) overlapping the air outlet 37. The boundary guide plate 38 is provided with a step, so that the reliability of connection of the boundary guide plate 38 on the air outlet 37 is improved.

As shown in fig. 1, the lowest point of the U-shaped baffle 36 is preferably lower than the lowest point of the air outlet 37 to prevent water that is directed along the U-shaped baffle 36 to the bottom of the U-shaped baffle 36 from entering the engine from the air outlet 37.

In the embodiment shown in fig. 1, the dividing baffle 38 and the U-shaped baffle 36 are both vertically connected to two opposite inner walls of the wading throat body 1, and the dividing baffle 38 is arranged substantially along the diameter of the air outlet 37 and substantially along the direction of the inlet airflow in the middle of the U-shaped baffle 36.

In order to improve the connection reliability of the U-shaped guide plate 36, the inner wall of the wading hose body 1 is provided with a supporting plate 35 for limiting the U-shaped guide plate 36, as shown in fig. 1 and 2, the U-shaped guide plate 36 is limited and supported, and the problem that the U-shaped guide plate 36 is deformed due to air flow impact can be solved.

As shown in fig. 1 to 4, the second drainage structure 34 includes a drainage valve 341 disposed at the gas outlet end 3 and a protective cover 343 fixed to an outer side of the drainage valve 341, and the protective cover 343 is provided with a second drainage hole 342. Since the one-way drain valve of the wading throat body 1 is made of soft material and is directly exposed to the outside, and is easily damaged, the protective cover 343 is further disposed on the outer side of the second drain structure 34 in this embodiment, and the protective cover 343 is disposed with the second drain hole 342. After the protective cover 343 is added, the water discharge valve can be prevented from being damaged maliciously and from being aged by illumination, and the water discharge valve can be prevented from being damaged. The first drain hole and the second drain hole 342 form two-stage drainage, water collected at the bottom of the U-shaped guide plate 36 is drained to the drain valve 341 from the first drain hole, and finally flows out of the pipeline through the second drain hole 342 of the protective cover 343, so that the air filter and the normal use of an engine are ensured.

As an alternative embodiment, as shown in fig. 1, the protective cover 343 is detachably connected to the air outlet end 3, and alternatively, the protective cover may be screwed or snapped in other connection manners.
