[0046] The urine treatment mechanism includes a urine treatment device 6 arranged in the feces and urine treatment box 1, the urine treatment device 6 is connected with the other group of discharge pipes 21, and the bottom of the urine treatment device 6 is provided with a water storage tank 61 connected with the water outlet thereof, as shown. Figure 8 As shown, the outer wall of the water storage tank 61 is fixedly provided with two groups of piston cylinders 62, the bottom of the pressing column 25 is hingedly connected with a connecting rod 63, the other end of the connecting rod 63 is hingedly connected with a movable rod 64 in sealing sliding fit with one group of piston cylinders 62, the outer wall of the connecting rod 63 is fixedly provided with two groups of piston blocks 65, one group of piston blocks 65 is located on one side of one group of piston cylinders 62, and the other group of piston blocks 65 is located in the inside of the other group of piston cylinders 62, so as to treat the urine into reclaimed water through the urine treatment mechanism, and to perform twice extrusion and conveying of the reclaimed water, and to flush the basin 2 before and after using the toilet.

[0047] The outer wall of the two groups of piston cylinders 62 is connected with water conveying pipes 66, and the inside of the basin 2 is provided with water spraying pipes 67, the bottom of the water spraying pipes 67 is uniformly provided with water spraying openings towards the inner wall of the basin 2, the outer wall of the water spraying pipes 67 is connected with a connecting pipe 68 penetrating into the inside of the feces and urine treatment box 1, and the other end of the two groups of water conveying pipes 66 is connected with the connecting pipe 68 through a one-way valve, so as to convey the reclaimed water to the water spraying openings at the bottom of the water spraying pipes 67 to be sprayed out, and the reclaimed water conveyed by one group of water conveying pipes 66 will not be conveyed into the other group of water conveying pipes 66 under the action of the one-way valve, so as to avoid backflow.

[0048] Working principle: when using the environmental-friendly toilet based on fertilizer collection and utilization, the user squats on the pressing plate 24, the pressing plate 24 moves downward under the action of gravity and presses the return spring 23, when the user uses the toilet, the urine enters the urine treatment device 6 through a group of excretion pipes 21, and the excrement enters another group of excretion pipes 21, the cover plate 26 at the bottom of the other group of excretion pipes 21 is opened by the torsional spring when it is pressed by the weight of the excrement, and the excrement enters the stirring box 31, and when there is no excrement, the cover plate 26 is closed by the torsional spring, when the pressing plate 24 moves to the top end of the toilet bowl 2, the pressing plate 24 presses the control switch 5, and the pressing plate 24 drives the top rack 59 to move downward and drives the left second gear 57 to rotate, under the action of the left second ratchet mechanism 58, the second gear 57 will not drive the first bevel gear 54 to rotate, and the control switch 5 controls the electric telescopic rod 51 to start, the telescopic end of the electric telescopic rod 51 drives the counterweight 52 to move upward to the maximum distance, the counterweight 52 drives the bottom rack 59 to move upward, and the bottom rack 59 drives the right second gear 57 to rotate, since the left and right second ratchet mechanisms 58 are symmetrically arranged, the right rack 59 drives the second gear 57 to rotate in the process of moving upward, and the second gear 57 will not drive the right first bevel gear 54 to rotate;

[0049] When the user finishes using the toilet, the feces is discharged into the stirring box 31, and the user gets up and leaves the pressing plate 24. At the moment of leaving the pressing plate 24, the reset spring 23 drives the pressing plate 24 to move upward and reset instantaneously. The pressing plate 24 drives the left rack 59 to move upward. At this time, under the action of the left second ratchet mechanism 58, the left second gear 57 drives the left first bevel gear 54 to rotate rapidly. The first bevel gear 54 drives the second bevel gear 55 to rotate rapidly. The second bevel gear 55 drives the rotating shaft 32 to rotate rapidly, and the rapidly rotating stirring rod 33 breaks the feces in the stirring box 31. In the process of rapidly breaking the feces, the control switch 5 is not pressed, so the electric telescopic rod 51 is closed. Because the weight of the counterweight 52 is greater than the sliding resistance when the electric telescopic rod 51 is retracted, the electric telescopic rod 51 is slowly retracted and reset under the action of the counterweight 52. The counterweight 52 drives the bottom rack 59 to slowly move downward and drives the second gear 57 to rotate. At this time, under the action of the right second ratchet mechanism 58, the right second gear 57 drives the right first bevel gear 54 to rotate. The first bevel gear 54 drives the second bevel gear 55 to drive the rotating shaft 32 to rotate slowly in the opposite direction until the electric telescopic rod 51 is completely reset. Similarly, at this time, the second bevel gear 55 drives the left first bevel gear 54 to rotate, which will not drive the left second gear 57 to rotate under the action of the left second ratchet mechanism 58.

[0050] Therefore, in the process of rapid rotation and slow rotation of the rotating shaft 32, the push rod 36 at the top of the stirring rod 33 rotates to the outer wall of the baffle 35, which can drive the cover plate 26 to rotate. At this time, the fermentation material pre-stored in the box 34 falls into the stirring box 31 through the bottom discharge port. When the push rod 36 rotates past the baffle 35, the baffle 35 rotates and resets under the action of the vortex spring and blocks the discharge port. Therefore, the fermentation material in the box 34 falls into the stirring box 31 indirectly during the rotation of the rotating shaft 32. Therefore, the broken feces and fermentation material can be stirred and mixed for fermentation during the slow rotation of the rotating shaft 32, and the fermentation decomposition speed is faster.

[0051] The pressing column 25 is driven to move downward by the pressing plate 24, and drives the first gear 43 to rotate through the outer wall toothed plate. Under the action of the first ratchet mechanism 44, the first gear 43 drives the conveying shaft 41 to rotate. During the process of squatting under the pressing plate 24, the conveying shaft 41 conveys the excrement mixed and stirred by the previous user in the stirring box 31 to the collecting box 3 for collection and fermentation. After using the toilet, the pressing plate 24 moves upward, and the first gear 43 does not drive the conveying shaft 41 to rotate reversely under the action of the first ratchet mechanism 44, so that the excrement mixed and stirred by the previous user can be conveyed to the right each time a user is replaced, and finally conveyed to the collecting box 3.

[0052] Secondly, the treated water obtained after the urine enters the urine treatment device 6 flows into the water storage tank 61. When the pressing plate 24 moves downward, the pressing column 25 drives the movable rod 64 to slide to the right through the connecting rod 63, and the movable rod 64 drives the right piston block 65 to move and be clamped into the right piston cylinder 62. Since the right piston cylinder 62 is filled with water, the piston block 65 slides in the piston cylinder 62 while extruding the water in the piston cylinder 62, and the water is conveyed to the water spraying pipe 67 through the right water conveying pipe 66, the one-way valve, and the connecting pipe 68, and sprayed out through the water spraying port at the bottom of the water spraying pipe 67, so as to pre-flush the bedpan 2 and make the inner wall of the bedpan 2 wet, avoiding the excrement from adhering to the inner wall of the bedpan 2. When the pressing plate 24 moves upward and resets, the pressing column 25 drives the movable rod 64 to slide to the left through the connecting rod 63. At this time, the left piston cylinder 62 is filled with water, and the water is conveyed to the water spraying pipe 67 through the left water conveying pipe 66, the one-way valve, and the connecting pipe 68, and sprayed out through the water spraying port at the bottom of the water spraying pipe 67, so as to flush the bedpan 2 after the user uses the toilet. During the flushing process, the water flowing into the left discharge pipe 21 is treated again by the urine treatment device 6, and the water flowing into the right discharge pipe 21 enters the stirring box 31 through the opening of the cover plate 26 and is conveyed to the collecting box 3.

[0053] Finally, the fermented and decomposed fertilizer can be recycled by opening the lid at the right top of the excrement and urine treatment box 1. The gas generated during the fermentation and decomposition of the excrement in the collecting box 3 and the stirring box 31 is discharged through the exhaust pipe, and the activated carbon adsorption box at one end of the exhaust pipe adsorbs the peculiar smell in the discharged gas, avoiding air pollution caused by the peculiar smell of the discharged gas.
