The working principle of the ecological toilet is as follows:

When the toilet personnel go to the toilet, first open the toilet cover 19, the personnel sits on the toilet main body 2 conveniently, the stool will fall on the first receiving plate 9, and the urine flows into the inner wall along the toilet main body 2 front half and is arranged on the The urinary catheter 14 at the front end flows to the urine storage barrel 18 through the fluid guiding system. When the toilet lid 19 is opened, the axial flow exhaust fan 4 is powered on and started, and a lot of odor is generated when people are convenient. Under the double action of the exhaust fan 4 and the chimney effect, a negative pressure zone is quickly formed in the air seal ring 11, Therefore odor can enter the air seal ring 11 from the gap between the first-level receiving plate 9 and the excrement outlet, both sides of the urinary catheter, and then be discharged outdoors. The forced ventilation when going to the toilet prevents the odor from being lost to the toilet space, which greatly guarantees the experience of going to the toilet. After using the toilet, click the control button 12 on the control panel of the ecological toilet to perform the flushing operation. After the control button 12 is pressed, the control system receives the control signal, and then controls each component to achieve subsequent actions:

On the one hand, the control system controls the first motor 6 to drive the first screw mandrel 7 to rotate forward, so that the first-stage receiving plate 9 moves backward. During the movement, the first scraper on the first-stage receiving plate 9 moves the first The feces on the stage receiving plate 9 are scraped to the second receiving plate 10, and then the first motor 6 reverses to drive the first screw mandrel so that the first stage receiving plate 9 is reset.

On the other hand, the control system controls the submersible pump in the water storage tank 1 to start, and the water stored in the water storage tank 1 flows to the first receiving plate 9 through the toilet nozzle, so that the remaining feces particles on the first receiving plate 9 The flushing, the waste water after flushing flows into the urinary catheter 14 and reaches the liquid flow control valve 30 through the catheter tube 15. At this time, the liquid flow direction control valve 30 has been adjusted to communicate with the second flow guide tube 23 under the control of the control system. Therefore, the flushing water after flushing flows into the second guide pipe 23 through the liquid flow control valve 30 and then enters the filter tank 20. The control system controls the submersible pump to stop running according to the set time, and then the control system controls the liquid flow control valve 30 to change to It communicates with the first guide tube 16 so that the fluid can flow to the urine storage bucket 18 . At the same time, after the first receiving plate 9 returns, the stool has dropped on the second receiving plate 10. At this time, the control system controls the rotation of the second motor 41 to drive the second screw rod 42 to move and drive the second receiving plate 10 toward the second receiving plate 10. The motor 41 moves, and the stool on the second receiving plate 10 is pushed by the second scraper. With the movement of the second receiving plate 10, the stool falls into the dung storage urn 17 due to gravity. When the second receiving plate 10 moves After reaching the set position, the second motor 41 reversely rotates to drive the second screw mandrel 42 to move and drive the second receiving plate 10 to return to the position and seal the manure dropping port 37 on the manure storage urn 17 .

Citric acid can be added through the acid inlet 34 in the dung storage vat 17, and the feces can reduce fermentation under the action of citric acid in the dung storage vat 17, keep the activity of the feces, and facilitate subsequent utilization. After the toilet has been used for a period of time, special personnel will collect the feces and urine in the area uniformly. The recovered feces rely on the engineering project, that is, the high-quality raw material of feces will be used as the fermentation raw material of the biogas project, and the fermented biogas residue will be returned It can be used as fertilizer for secondary utilization, and the manure resources are used for secondary utilization. Urine is used to extract scarce nutrients such as phosphorus, nitrogen, and urokinase.

The ecological toilet solution in the present invention can be applied to various scenarios, such as rural bungalow type, public toilets in scenic spots, and building type household toilets.

It should be noted that during the process of urinating or defecating, the operation of the ventilation system can ensure that the peculiar smell of the entire device is sucked away, ensuring the air circulation of the entire toilet, which is clean and environmentally friendly. The effect can also ensure that the interior of the toilet body 2 always maintains a slight negative pressure, and can always ensure the freshness of the environment around the toilet.
