When the flushing instruction is issued, the first drive motor 3-2 is driven by the control unit to drive the cover 3-1 to slide up. When the cover 3-1 slides into place and closes the excrement outlet 2-2, the compartment limit switch 11 in front of the flushing water pump switch is triggered. At this time, the flushing system works to spray water, and the cleaning waste water enters the urine collection pot 9 through the cover 3-1 and the urine collection tank 11.

[0067] In this example, the cover plate 3 - 1 is arranged upwardly and tilted from front to back, so that after cleaning is completed, the cleaning waste water flows through the cover plate 3 - 1 to the urine outlet 2 - 1 and enters the urine collection pot 9 .

[0068] The working principle of this utility model is:

[0069] When a person goes to the toilet, the sensing component senses the human body and transmits a signal to the control unit. The control unit controls the first drive motor 3-2 to drive the cover 3-1 to move to the front side of the barrel body 1, opens the excrement outlet 2-2, and human excrement enters the biodegradable barrel 4 through the excrement outlet 2-2, and urine enters the urine collection pot 9 through the urine outlet 2-1. After the excretion is completed, the cleaning switch is turned on, and the cleaning switch, the sliding cover mechanism 3 and the compartment limit switch 11 are linked. When the flushing instruction is issued, the control unit controls the first drive motor 3-2 to drive the cover 3-1 to slide up. When the cover 3-1 slides into place and closes the excrement outlet 2-2, the compartment limit switch 11 in front of the flushing water pump switch is triggered. At this time, the flushing system works to spray water, and the cleaning wastewater flows through the cover 3-1 and the urine collection pool 11 to the urine collection pot 9.

[0070] In summary, this toilet can achieve the dry and wet separation of excrement and urine, ensuring the efficiency of biodegradation.
