To keep the pudenda or the like of the user clean after the discharging while dispensing with the replacement of the drier.
An air compressor 205 which gets the inside of a discharge tank 200 evacuated to a negative pressure is provided with a plurality of compression parts A and B and the connection is made between the suction port sides and the blow-off port sides of the respective compression parts A and B through two-way valves E and F. As a result, when sucking the excrements in a filth collection cup 120 of a diaper 12 wrapping the waist/hip part of the user, the two-way valves E and F are opened to make the compression parts A and B communicate with each other to operate so that the function as a high flow rate compressor is performed to suck the excrements. After the washing of the anus and the pudenda of the user, the two-way valves E and F are closed to make the compression parts A and B independent of each other. Thus, the outside air is blown into the filth collection cup 120 with the compression part A while the outside air circulated through the filth collection cup 120 can be sucked with the compression part B.
