Two ends of the branch pipe (13) respectively are connected to the air feeder pipe (11) and to the feces feeder pipe (12). The structure supports a feces transportation apparatus to remove residual feces in a feces extraction pipe of the feces transportation apparatus when a feces extraction is completed. Employment of the present allows for the removal of residual feces from the feces extraction structure, for the entire feces extraction process to be free of fecal dripping and of foul odor leakage and to be hygienic and environmental, and for the operation to be simple, convenient, and efficient.</p> |
