A stool collection device (100), comprising a bearing structure (20) and supporting structures (30). A containing cavity (21) is provided at a middle portion of the bearing structure (20), the containing cavity (21) being provided with an inlet, and the containing cavity (21) communicating with the exterior of the bearing structure (20) by means of the inlet. The bearing structure (20) is provided with a breakable area (22). The supporting structures (30) are connected to the bearing structure (20), and the supporting structures (30) comprise an intermediate portion (31) and an extending portion (32) connected to the intermediate portion (31), a side of the intermediate portion (31) away from the extending portion (32) being connected to the bearing structure (20), and the extending portion (32) being provided with a connection member (33). When in use, a user detachably connects the stool collection device (100) to a squat toiler or a sit toilet by means of the supporting structures (30), and the user defecates normally as usual, thus stool can be collected； after a required amount of a sample is collected, the bearing structure (20) is ruptured or broken by means of the breakable area (22), and excess stool fall into the squat toiler or sit toilet without additional processing, then the used stool collection device (100) can be discarded in a garbage collector.
