The invention discloses a sanitary cup which comprises a cup, a drain pipe, drain holes and a switch gear. The drain pipe is communicated with the bottom of the cup, the drain holes are formed in the drain pipe, and the switch gear acts on the drain pipe, so that liquid can flow through the drain pipe to be drained from the drain holes under the control of the switch gear. During usage, the switch gear is turned off, then both the switch gear and the cup are placed into a human body, and the liquid flows into the cup and is stored in the cup; a user pulls the switch gear along the drain pipe or a pull handle out of the body of the user after a period of time, the pull handle is arranged on the cup, but the cup still remains in the body of the user, then the switch gear is turned on, and the liquid stored in the cup can flow through the drain pipe from the cup and is drained from the drain holes; the switch gear is turned off, and is pushed into the body of the user again, so that the cup can be located at a corresponding position in the human body. The sanitary cup has the advantages that the sanitary cup does not need to be frequently replaced or cleaned, is free of constraints on service places, can be used easily and conveniently as compared with an existing sanitary cup, and is high in user experience satisfaction.
