Specifically, the preset procedures are as follows: when the detecting device 801 detects that there is excrement on the diaper 40, the controller 80 firstly controls the extension of the push rod of the electric push rod 60, and then drives the first rotating door 30 to rotate from the closed state to the open state, so as to replace the diaper 40; meanwhile, the second rotating door 50 rotates from the open state to the closed state, and the electric push rod 60 is controlled to stop running; then, the water pump 703 is controlled to work, so that the spray head sprays water to the buttocks of the patient to wash away the residual excrement on the buttocks of the patient, the sprayed water falls into the cleaning basin 70 and is discharged through the drain pipe 701, and the water pump 703 is controlled to stop working after the cleaning is finished; then controlling the fan 704 to work, and meanwhile heating wires in the fan 704 generate heat to blow air with higher temperature to the buttocks of the patient so as to evaporate water at the buttocks of the patient, and controlling the fan 704 to stop working after the water on the buttocks of the patient disappears; then, the push rod of the electric push rod 60 is controlled to contract inwards, so as to drive the first rotating door 30 to rotate from the open state to the closed state, and at the same time, the second rotating door 50 rotates from the closed state to the open state.

After the detection device 801 detects that there is excrement on the diaper 40, the controller 80 does not control the operation of the electric push rod 60, the water pump 703 and the fan 704 even if the detection device 801 detects that there is excrement on the diaper 40 again within a preset time interval; so as to prevent sweat or other external factors of the patient from interfering, and further to cause the controller 80 to control the electric push rod 60, the water pump 703 and the blower 704 to continuously perform the preset process, thereby influencing the rest of the patient. Preferably, the preset time may be 15 minutes or 20 minutes, and in the embodiment, the preset time is 30 minutes.

Preferably, the conveying motor 401 is also electrically connected to the controller 80, so that the conveying motor 401 is controlled to operate when the first rotating door 30 rotates from the closed state to the open state, or when the first rotating door 30 is in the open state, so that the conveying shaft 402 drives the diapers 40 to move towards the first rotating door 30, and then the used diapers 40 fall, and new diapers 40 are run onto the first rotating door 30 to complete the automatic replacement of the diapers 40.

Preferably, the detection means 801 may be any means capable of detecting the presence of waste on the diaper 40, such as: the detecting device 801 comprises two metal wires which are arranged at intervals, both the two metal wires are electrically connected with the controller 80, when excrement exists on the diaper 40, the humidity of the diaper 40 is increased, so that the resistance value between the two metal wires which are in contact with the diaper 40 is changed, and further an operation signal is generated; alternatively, the detecting device 801 includes a humidity sensor electrically connected to the controller 80, the humidity sensor is used for detecting the humidity of the diaper 40, when the diaper 40 has excrement, the humidity of the diaper 40 is increased, and the humidity sensor generates an operation signal.

Specifically, a first position detector 802 is provided on the frame 10, and the first position detector is configured to send a first signal to the controller 80 when detecting that the first rotating door 30 is in the open state, so that the controller 80 controls the operation of the conveyor motor 401 to replace the diaper 40 on the first rotating door 30.

Further, a second position detector 803 is disposed on the bed plate 20, and the second position detector 803 is configured to send a second signal to the controller 80 when detecting that the second rotating door 50 rotates to the closed state, so that the controller 80 controls the water pump 703 to operate to wash the buttocks of the patient.

Preferably, the first position detector 802 may be a pressure sensor that is touched when the first swing door 30 is in the open state, thereby causing the pressure sensor to generate a first signal; the second position detector 803 may also be a pressure sensor that is touched when the second swing door 50 is in the closed state, thereby generating a second signal. Or both the first position detector 802 and the second position detector 803 may be travel switches.
