Ventilating disk assembly

An improved ventilating disk assembly, comprising a circular ring, a resilient foot disk, a ventilating disk, a biasing rod, a basement and an upper and lower nuts, characterized in that

• said circular ring being configured to have an U-shape cross section having a plurality of holes thereof,
• said resilient foot disk being configured with a circular configuration having a through hole in the central portion, said further including a plurality of legs extending radially and outwardly from the peripheral, each of said legs being extended downward and provided with a projection thereunder;
• said ventilating disk being provided with a truncate portion in the central portion, said truncate portion being provided with a through hole in the central portion, a plurality of coarse holes corresponding to those of said projections of said resilient foot disk being provided on said ventilating disk away from said truncate portion;
• said ventilating disk further including a plurality of I-shape fine holes, the peripheral said ventilating disk being provided with a plurality of holes;
• said biasing rod being configured with a disk configuration having an upper bolt and a lower bolt thereof, each of said upper and lower bolts being provided with a threaded portion the free end portion, the peripheral of said biasing rod being provided with a plurality of holes;
• and
• said basement being configured with a circular configuration having an inclined surface directed inwardly from the outer peripheral, the peripheral of said basement being provided with a concentric ring said concentric ring being also provided with a plurality of through hole, said concentric ring further including an annular slot having a through hole in the central portion, the outer peripheral of the through hole being provided with a plurality of air delivery holes having connected with a delivery pipe thereof;
• in assembling those described components, said biasing rod being firstly disposed between said ventilating disk and said basement such that said upper bolt can pass through the through holes of said ventilating disk and then inserts into said central through hole of said foot disk, then said upper nut being screwed onto said threaded portion of said upper bolt to position said resilient foot disk, meanwhile, a plurality of screws being applied to insert into said holes said circular ring, said ventilating disk and said basement such that said ventilating disk can be positioned, on the other hand, said lower bolt of said biasing rod being passed through said through hole of said basement, then said lower nut being applied to screw onto said threaded portion of said lower bolt.
