A non-water lavatory flushing device consists of a electrical four-way valve, which one of its exit is connected with the exit of the side wall of the valley at the back of the toilet pan for collecting the feces. The three exits are connected with the central part of the toilet pan, feces collecting box and the flushing liquid collecting box through a feces dispersing pipe, a feces collecting pipe and a urine collecting pipe. The non-water lavatory flushing device of the invention uses a four-way valve to replace the feces dispersing pipe magnetic valve, feces collecting pipe magnetic valve and urine collecting pipe of the prior art. The dispersed feces liquid and urine in the feces dispersing pipe, feces collecting pipe and urine collecting pipe is controlled by the four-way valve respectively. Then the structure is simplified and the cost is decreased. Furthermore, as the four-way joint is cancelled, the problem of wrong flowing of the leaving liquid is solved. Thus, it could be avoided that the feces plasm flow into flushing liquid collecting box or the limited clean urine is discharged along the feces collecting pipe and this is advantaged to improve the flushing effect. |
