<p>A negative-pressure pipe residual feces removing mechanism arranged on a feces storage apparatus, comprising a feces discharging conduit (8) and a fluid draining conduit (3) connected to the feces discharging conduit (8). The feces discharging conduit (8) has arranged thereon a feces discharging valve (7), and the fluid draining conduit (3) has arranged thereon a draining valve (2). During a feces extraction, the feces discharging conduit (8) has externally connected thereto a feces extraction-transportation apparatus, and throughout the entire working operation, the feces extraction-transportation apparatus continuously maintains a negative pressure, thus no positive pressure is allowed to enter a feces storage tank (1). Hence, the need for a special pressure-bearing processing for the feces storage tank (1) is obviated, and operational safety is ensured for the feces storage tank (1) and for other apparatus thereof connected to the feces storage tank (1), and as the entire process of the feces extraction is kept under negative pressure, outward diffusion of accumulated foul odor within the feces storage tank (1) is avoided. In addition, the feces extraction by means of negative pressure and the removal of residual feces in the pipe do not require additional specialized mechanism for the feces extraction-transportation apparatus. The auxiliary negative-pressure feces extraction pipe residual feces removing mechanism for addition to feces storage facility is provided with the characteristics of simple structure, low costs, and easy operation.</p> |
