Specific implementation mode
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art
The utility model may be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
In following implementation, the "front", "rear", "bottom" etc. are described as described in the orientation in opposite attached drawing 1.
Fig. 1 is referred to, the utility model discloses a kind of air inlet structures of fresh air system, are mainly installed on outdoor,
Including a shell 1, the foreboard 11 of shell 1 is equipped with the ventilation opening 13 of multiple vertical bar shapes, and the back plate 12 of shell 1 is connected with intake stack
2, the inside of shell 1 is equipped with a water bar 3 corresponding to each ventilation opening 13, and water bar 3 includes first be connected with each other
Baffle 31 and second baffle 33, it is at an acute angle between first baffle 31 and foreboard 11, be between second baffle 33 and first baffle 31
Obtuse angle.The air inlet structure of the present embodiment, when rainwater enters in ventilation opening 13, by the blocking of first baffle 31, to suitable
It first baffle 31 to flow on the bottom plate of shell 1, without being entered in intake stack 2 with air-flow, improves fresh air system
Water resistance.Secondly, second baffle 33 plays the role of guiding between air-flow, with first baffle 31 in obtuse angle, reduces
The loss of wind pressure.
In order to improve the wind-guiding effect of second baffle 33, the loss of wind pressure is reduced, it is preferred that first baffle 31 and second gear
It is connected by an arc panel 32 between plate 33.Effect of the angle between second baffle 33 and first baffle 31 for wind-guiding simultaneously
There is important relationship, when second baffle 33 is parallel with the both side plate 15 of shell 1, wind effect is best.
Utility model people has found that the angle between the water blocking effect and first baffle 31 and foreboard 11 of first baffle 31 has weight
The relationship wanted.Angle is bigger, and the water blocking effect of first baffle 31 is poorer, but the loss of wind pressure is smaller；And angle is smaller, first
The water blocking effect of baffle 31 is better, but the loss of wind pressure is bigger.It is, thus, sought for a suitable angle, to reach gear
The balance of water effect and air loss.Utility model people is by the study found that when the angle between first baffle 31 and foreboard 11
When being 30-60 °, first baffle 31 has preferable water blocking effect, while the loss of wind pressure is in acceptable range.
In the present embodiment, multiple vertical guiding gutters 311 are provided on first baffle 31, to guide water along guiding gutter
311 are flowed on the bottom plate of shell 1.Guiding gutter 311 is preferably semicircle or U-shaped guiding gutter 311.
In order to which the ponding in shell 1 is discharged, it is preferred that the bottom plate of shell 1 is equipped at least one osculum (not shown).
In some embodiments, the bottom plate of shell 1 is configured to be obliquely installed, and osculum is set to lower side on bottom plate, enters
Lower side on bottom plate can be flowed to the ponding in shell 1, and is discharged outside shell 1 by osculum.
In the present embodiment, the back plate 12 of shell 1 is equipped with funnel-form wind-guiding joint 14, and intake stack 2 is connected to wind-guiding and connects
First 14 oral area.The funnel-form wind-guiding joint 14 plays the role of that air-flow is guided to enter intake stack 2,14 mouthfuls of wind-guiding joint
The position in portion is higher than the bottom plate of shell 1, avoids the occurrence of the case where ponding enters intake stack 2.
Embodiment described above is only the preferred embodiment lifted to absolutely prove the utility model, the utility model
Protection domain it is without being limited thereto.Those skilled in the art on the basis of the utility model made by equivalent substitute or change
It changes, both is within the protection scope of the present invention.The scope of protection of the utility model is subject to claims.
