In a preferred embodiment, the excrement storage jar 17 is further provided with an inspection manhole 44, and the cover can be opened for inspection when the excrement storage jar 17 runs for a long time and is abnormally blocked.

In practical application, the ecological toilet can be applied to an ecological courtyard, can be used for collecting and treating organic wastewater such as hand washing water, bath water, laundry water and the like, enters the plant filter tank after being collected, is separated by the partition plate, flows to the purified water collecting tank after being treated with toilet flushing water respectively, is recycled, and has a good application prospect.

The working principle of the ecological toilet is as follows:

when a person goes to toilet, firstly, the toilet lid 19 is opened, the person can sit on the toilet main body 2 conveniently, the excrement falls on the first receiving plate 9, and the urine flows into the urine guide groove 14 arranged at the front end along the inner wall surface of the front half part of the toilet main body 2 and flows to the urine storage barrel 18 through the liquid guide system. When the toilet cover 19 is opened, the axial flow fan 4 is powered on and started, odor is generated more when people are convenient, and a negative pressure area is quickly formed in the air seal ring 11 under the double effects of the fan 4 and the chimney effect, so that the odor enters the air seal ring 11 from gaps between the first-stage bearing plate 9 and the feces dropping port and the urethral catheterization grooves on the two sides and is then discharged outdoors. Forced exhaust when like the lavatory makes the foul smell can not lose the lavatory room space completely, very big assurance like the lavatory experience. After like the lavatory, click control button 12 on the ecological lavatory control panel and wash the operation, control button 12 presses the back, and control system receives control signal, and then controls each part and realizes follow-up action:

on the one hand, the control system controls the first motor 6 to drive the first screw rod 7 to rotate forwards, so that the first stage bearing plate 9 moves backwards, in the moving process, the first scraper on the first stage bearing plate 9 scrapes excrement on the first stage bearing plate 9 to the second bearing plate 10, and then the first motor 6 rotates backwards to drive the first screw rod to reset the first stage bearing plate 9.

On the other hand, the control system controls the submersible pump in the water storage tank 1 to be started, water stored in the water storage tank 1 flows to the first receiving plate 9 through a water spraying opening of the toilet, so that residual excrement particles on the first receiving plate 9 are washed, the washed waste water flows into the urine guide groove 14 and reaches the liquid flow direction control valve 30 through the liquid guide pipe 15, the liquid flow direction control valve 30 is adjusted to be communicated with the second flow guide pipe 23 under the control of the control system, therefore, the washed washing water flows into the second flow guide pipe 23 through the liquid flow direction control valve 30 and then enters the plant filter 20, the control system controls the submersible pump to stop running according to set time, and then the control system controls the liquid flow direction control valve 30 to be communicated with the first flow guide pipe 16 so that fluid can flow to the urine storage barrel 18. Meanwhile, after the first bearing plate 9 returns, the excrement falls on the second bearing plate 10, at this time, the control system controls the second motor 41 to rotate to drive the second screw rod 42 to move and drive the second bearing plate 10 to move towards the second motor 41, the excrement on the second bearing plate 10 is pushed by the second scraper, along with the movement of the second bearing plate 10, the excrement falls into the excrement storage tank 17 due to the action of gravity, and after the second bearing plate 10 moves to a set position, the second motor 41 rotates reversely to drive the second screw rod 42 to move and drive the second bearing plate 10 to return and seal and cover the excrement falling port 37 on the excrement storage tank 17.

The ecological toilet scheme in the ecological toilet can be applied to various scenes, such as a rural flat-room type public toilet in a scenic spot, a building type household toilet.

It should be noted that, in the process of urination or defecation, the operation of the ventilation system can ensure that the peculiar smell of the whole device is absorbed away, the ventilation of the whole toilet is ensured, the device is clean and environment-friendly, and meanwhile, under the condition that no person goes to the toilet, the interior of the toilet main body 2 can be always kept at micro negative pressure due to the chimney effect, so that the refreshing of the surrounding environment of the toilet can be always ensured.

In the description of the present application, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience in describing the present application and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present application.

The foregoing description of the specific embodiments of the invention has been presented. It is to be understood that the present invention is not limited to the specific embodiments described above, and that various changes or modifications may be made by those skilled in the art within the scope of the appended claims without departing from the spirit of the invention.
