When the automobile is parked, the temperature in the automobile lamp is gradually reduced, the air pressure in the automobile lamp is reduced, when negative pressure is generated in the automobile lamp, the external atmosphere is dried and then is opened through the weak magnetic valve, dry air is supplemented into the automobile lamp until the internal pressure and the external pressure are balanced, and the weak magnetic valve is kept closed under the action of self weight and magnetic force.

The defogging working principle of the invention applied to other shell spaces is the same as that of the vehicle lamp shell.
The weak magnetic valve is innovative and applied, does not need electric power or mechanical transmission drive, and is opened and closed only by air pressure difference on two sides of the valve, so that the product structure is small and exquisite, the resistance moment generated by weak magnetic force is small, and the valve can be opened sensitively by slight pressure difference change inside and outside the car lamp, thereby finishing the capacities of outwards discharging hot damp and inwards supplementing dry air.
