<p>The present invention discloses an airtight cover provided with a sterilizing and deodorizing agent for a toilet bowl, including: a seat (10) provided with a defecation opening (11), a sealing ring connection part (12) arranged along the lower peripheral surface, and a sealing ring (13) connected to the sealing ring connection part (12) for contacting the upper end of the bowl in an airtight manner; a first cover (20) inserted in the defecation opening (11) with the peripheral surface snugged in the inside of the defecation opening (11) having a projected closing part (22) with a ventilation hole (21) and an upper end provided with a first connection part (23); a sterilizing and deodorizing agent part (30) inserted inside the closing part (22) of the first cover (20) with an upper and a lower part having respective ventilation parts (31) and (32); and a second cover (40) having a lower part provided with a second connection part (41) arranged at the position corresponding to the first connection part (23) for closing the upper end of the first cover (20), an external ventilation hole (42) being formed in the second cover. The present invention prevents offensive odor or bacteria from escaping through a gap created between the upper end of the bowl and the seat by means of the sealing ring. When flushing the toilet after defecating, the opening of the seat is closed by the cover closing part so as to prevent the surface of the seat from being contaminated, the external air flows through the ventilation hole of the cover into the bowl so as to diffuse the sterilizing and deodorizing agent through the inside of the bowl thus always keeping the toilet clean, and the double structure of the cover part consisting of the first and the second makes it easy to replace the sterilizing and deodorizing agent by simply separating the first and the second cover, significantly improving usability and convenience.</p> |
