The utility model provides a novel on-vehicle no resistance wind channel mouth structure does not have the grid device, and the noise is little, and the windage is little.

The specific technical scheme is as follows:

The utility model discloses a novel vehicle-mounted resistance-free air duct opening structure, which comprises a face cover, a base and a bottom cover;

the base is arranged at the front end of the bottom cover, and the face cover is arranged at the front end of the base;

the base comprises an inner ring and an outer ring; the outer ring is connected with the bottom cover, the inner ring and the outer ring are fixedly connected into a concentric structure, holes are formed in the side wall of the inner ring, gas diffuses to the periphery through the holes to form uniform airflow, and the inner wall of the outer ring is set to be an Archimedes curve, so that the gas blown out of the holes is blown out spirally.

Further, the inner wall of the outer ring can be adjusted, and then the direction and the size of the airflow can be adjusted.

further, novel on-vehicle no resistance wind channel mouth structure still includes the filter screen, the filter screen sets up the base with between the face lid.

Further, novel on-vehicle no resistance wind channel mouth structure still includes well cover, well cover sets up the filter screen with between the base, well cover is the ring shape structure, the filter screen is inlayed in the well cover.

Furthermore, a power supply jack is arranged on the side wall of the middle sleeve.

Further, the power jack is a DC12 power jack.

Furthermore, the surface cover and the middle sleeve are respectively provided with a thread and a screw which are matched with each other. It is convenient when the change of filter screen, prevent the face lid with well cover relative rotation.

The utility model has the advantages that:

Simple structure, the amount of wind is big, and the filter area is big, changes the wind direction and does not rely on the grid, and the windage is little, and the noise is little.
