ABSTRACT:
The present invention relates to an improved ventilating disk assembly. When the air pressure applied thereof is changed, different stirring effect can be attained and the debris or soil accumulated onto the ventilating disk can be readily removed. The improved ventilating disk assembly comprises a ventilating disk, a resilient foot disk, a biasing rod and a basement. Characterized in that the resilient foot disk is provided with a plurality of projections which are in align with a plurality of coarse holes distributed on the ventilating disk. When the pressure of the supplied air is lowered than a preset limit, the supplied air is injected from the fine ventilating holes. When the air pressure of the supplied exceeds the preset limit, the projections plugged within the coarse holes will be released such that the excess air can be ventilated through those coarse holes. By this arrangement, the resilient ventilating disk is prevented from being damaged. Furthermore, the vibration of the foot disk can be transmitted to the ventilating disk such that the debris accumulated thereof can be readily removed.
