The utility model discloses an assembled removes toilet, include: one side is equipped with the main part and the decontaminate car of setting in the main part below of step, other three sides of mainpart are equipped with at least one opening that is used for passing in and out the car of decontaminating, it is equipped with feces collecting box in the car to decontaminate, is equipped with thepreshoot formula urinal with the feces collecting box intercommunication on the top surface of the car of should decontaminating, the air compressor that feces collecting box's top was equipped with the power supply unit and was connected with the power supply unit electricity, this air compressor's the air output end and the bath mouth of preshoot formula urinal pass through the hose connection,it is equipped with the air inlet with supplying air compressor suction gas on the car to decontaminate. The beneficial effects are that: just, change atmospheric pressure into and dash just through dashing water pressure, can dash just device integration to the car of decontaminating in with atmospheric pressure to avoid the decontaminating too much contact of car and main part deviates from theoriginal intention of split type design. Simultaneously, atmospheric pressure dashes and just not to use the water resource, and the environmental protection is favorable to exerting feces collectingbox's maximum efficiency simultaneously.
