The present invention relates to a disposable cover for a cuspidor, which is provided, with replacement possibility, on the cuspidor for draining washing water after a patient washes a mouth to enable every patient to use a new cover, so that blood, body fluids, and secretions are prevented from remaining in the cuspidor, thereby hygienically managing the cuspidor. In addition, when comparing with an existing cuspidor employing steam or high-pressure water for washing, the cuspidor requires economical initial investment cost and economical maintenance and repair cost. In addition, a drain adapter coupled to a tip member is provided in a drainpipe, thereby preventing odor and insects from being introduced into the cuspidor from the drainpipe. According to a preferred embodiment of the present invention, the disposable cover for the cuspidor includes a cover body, the tip member, and the drain adapter. The cover body has an upper portion in the shape of an open housing and is securely provided on the dental cuspidor with replacement possibility. The bottom surface of the cover body is inclined downward toward an outlet so that the washing water can be naturally drained through the outlet provided in the center of the cover body. The tip member is coupled to the outlet at the center of the bottom surface of the cover body to guide a drain direction of the washing water drained through the outlet. The drain adapter has an inner part coupled to the tip member and is positioned in the drainpipe of the dental cuspidor. A plurality of drain holes are formed through the lateral side of the drain adaptor. The drain adaptor finally drains the washing water when the washing water drained through the tip member reaches the water level of the outlet.COPYRIGHT KIPO 2016본 발명은 환자가 입을 행군 세척수가 배수되는 타구대 상에 교체 가능하게 구비됨으로 인해 환자마다 새로운 커버가 사용될 수 있어 혈액, 체액, 분비물 등이 타구대 측에 잔존되는 것이 방지됨으로써 타구대가 위생적으로 관리될 수 있고, 스팀이나 고압수에 의해 세척되는 타구대에 비해서 초기투자비용과 유지 및 보수 비용이 저렴하며, 배수관 내에는 팁부재와 결합되는 배수 어댑터가 구비되어 있
