CLEANING APPARATUS, STERILIZING APPARATUS COMPRISING THE SAME, AND CLEANING RING USED THERETO

摘要

PURPOSE: A cleaning ring for cleaning a rod structure is provided to prevent the degradation of cleaning force with an elastic ring even if an inner circumference of the cleaning ring is worn out and to facilitate the disassembly of the cleaning ring. CONSTITUTION: A cleaning ring for cleaning a rod structure comprises an upper ring, a lower ring, and an elastic ring(50). The upper ring comprises upper first and second semi-circular rings(31,32) which are separated each other. The upper first and second semi-circular rings respectively comprise a protrusion portion with a horizontal coupling groove and an uneven portion. The lower ring comprises lower first and second semi-circular rings(38,39) which are separated each other. The lower first and second semi-circular rings respectively comprise a protrusion portion with a horizontal coupling groove and an uneven portion. The elastic ring is inserted in the coupling grooves of the upper and lower rings. The uneven portions and the protrusion portions of the upper ring are correspondently coupled to the protrusion portions and the uneven portions of the lower ring.
