Specific embodiment

With reference to the accompanying drawing and specific embodiment is described further the utility model.

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only to explain this Utility model is not used to limit the utility model.

As shown in Figure 1, present embodiment discloses a kind of vehicle exhaust intelligent filtering device, including filtering cabin 1, the filtering The gas inlet 15 in storehouse 1 is connect with automobile exhaust pipe, and filtering cabin 1 is made of metal, the serpentine-like distribution of internal duct, filtering cabin 1 is equipped with 1 side door of removable filter storehouse, and 1 side door of filtering cabin is located at 1 side of filtering cabin, and 1 side door of filtering cabin is fixed by four screws On filtering cabin 1；

Filter screen 3 is evenly distributed in filtering cabin 3 in pipeline, filter screen 3 is nylon filter, and filter screen 3 passes through filtering The bayonet 4 of 1 inner tube road of storehouse is caught in the pipeline in filtering cabin 1, and nylon filter is reusable, can unscrew 1 four jiaos of filtering cabin Four screws 2, open 1 side door of filtering cabin, filter screen 3 taken out from bayonet 4, be caught in after cleaning by bayonet 4, cover filtering 1 side door of storehouse tightens screw 2, and 3 top of filter screen is tilted toward tail gas circulating direction, prevents the focusing particles filtered from filtering 3 bottom of net；
