Side, and be connected and fixed between the first housing and the second housing.Described air draft grid end face enters described in being higher than
Air port end face, and shape is in an angle, angular range 60 °～120 °.
By above the technical solution of the utility model, compared with existing, it significantly has the beneficial effects that:
1, air draft grid end face is higher than air inlet end face, and the bucket-shaped inclined shape of passage backboard, outside can effectively stoping
Portion's rainwater enters, and silencing case is suitable to outdoor life-time service.
2, air draft grid end face is connected by bucket-shaped passage with air inlet end face, and forms one 60 °～120 °
Angle, silencing case working environment relative closure, effectively cut off the silencing case interior noise approach to external diffusion,
Reduce noise pollution.
3, air feed shutter window uses draw-in groove mode to fix with silencing case shell, and simple in construction is easy for installation.

Detailed description of the invention
In order to know more about technology contents of the present utility model, especially exemplified by specific embodiment and coordinate institute's accompanying drawings explanation
As follows.
It is described with reference to each side of the present utility model in the disclosure, illustrates shown in the drawings of many
Embodiment.Embodiment of the disclosure and must not be intended to include all aspects of the present utility model.Should be appreciated that
Multiple design presented hereinbefore and embodiment, and those design and the embodiment party described in more detail below
Formula can in many ways in any one is implemented, this is because design disclosed in the utility model and reality
Execute example and be not limited to any embodiment.It addition, the discloseder aspects of this utility model can be used alone,
Or otherwise any appropriately combined use disclosed in this utility model.
The air feed shutter window of a kind of silencing case of this utility model, this air feed shutter window includes air draft grid 1, air intake
Mouth 2 and bucket-shaped passage 3.
In conjunction with Fig. 1, Fig. 4, it is multiple be arranged in the first housing that air draft grid 1 has the first housing 101
Poroid passage 102；
Shown in Fig. 2, air inlet 2 has the second housing 201 and the air intake being arranged in the second housing leads to
