Description

The bearing circle of band blowhole

Technical field

The utility model relates to a kind of bearing circle, especially with the bearing circle of blowhole.

Background technology

Because how the bearing circle that present various self-propelled vehicle uses does not possess the function of regulating cold and hot temperature as required, cause summer in sweltering heat, chaufeur is had to put on one's gloves and is prevented that the palm of the hand from perspiring and skid, getting winter driving person in severe cold dare not hold ice-cold bearing circle in fact or have to put on clumsy mitten, however, cause to such an extent that traffic accident happens occasionally owing to operation is dumb.

Summary of the invention

The utility model gets purpose and is to provide a kind of simple in structure, with low cost, can utilize the bearing circle of the band blowhole of the cold air of motor vehicle air conditioning system or hot gas safely and effectively.

The technical scheme that its technical matters that solves the utility model adopts is: the bearing circle of band blowhole, comprise wheel rim 2, wheel hub 3, it is characterized in that: the breather pipe 4 that mutual perforation is arranged in wheel rim 2 and the wheel hub 3, well-distributed blowhole 1 is arranged on the wheel rim 2, blowhole 1 connects breather pipe 4, and the breather pipe 4 in the wheel hub 3 connects the blast pipe 5 at wheel hub 3 centers.

Beneficial effect: simple in structure, with low cost, safe and effective.
