The invention discloses a vacuum-negative-pressure remote control system of an intelligent human-body nursing instrument. The intelligent human-body nursing instrument comprises a shell, a feces collector, a wastewater bucket, a clear water bucket, a water feeding pump and a host, wherein the feces collector, the wastewater bucket, the clear water bucket, the water feeding pump and the host are installed in the shell. The vacuum-negative-pressure remote control system is characterized by comprising a vacuum treating system coupled with the host; the vacuum treating system comprises a negative pressure module and a positive pressure module; the negative pressure module is connected with the wastewater bucket to be used for sucking water in the feces collector, the positive pressure module is connected with the feces collector to be used for blowing air to the feces collector, and the blowing direction is towards a wastewater pipe; the positive pressure module is communicated with the negative pressure module through a vacuum pump, and the vacuum pump is coupled with the host; a wireless transmitting module is connected to the host, and wireless signals are transmitted and received through the wireless transmitting module; the system further comprises a remote communicating device communicated with the wireless signals. The vacuum-negative-pressure remote control system of the intelligent human-body nursing instrument is clean, sanitary, comfortable in use, safe and environmentally friendly, and has the remote control means at the same time.
