Description

Technical Field

[0001] This application relates to the field of toilet technology, and more particularly to an ecological toilet. Background Technology

[0002] Ecological toilets are a type of public toilet. In order to treat the excrement inside the toilet in a harmless manner, microbial decomposition technology can be used to decompose and process the excrement inside the toilet.

[0003] However, in areas with extreme weather conditions, such as cold, arid, and water-scarce regions, outdoor temperatures are low and there is no water source. Outdoor toilets may not be able to decompose excrement, leading to bacterial growth and significant environmental impact. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides an ecological toilet that ensures the normal decomposition of excrement inside the toilet by microorganisms, thereby improving the cleanliness of the environment surrounding the toilet in extreme environments.

[0005] This application is achieved through the following technical solution.

[0006] This application provides an ecological toilet, including a toilet stall, a collection and treatment device, a heat conduction channel, a heat collection plate, and a first fan. The toilet stall has a toilet opening. The collection and treatment device has a receiving space communicating with the toilet opening, wherein the receiving space is used to collect excrement discharged from the toilet opening and perform microbial treatment; the heat conduction channel is disposed on the collection and treatment device, and the outlet end of the heat conduction channel is connected to the outside of the toilet stall; the heat collection plate is disposed on the outside of the toilet stall and forms an airflow channel with the outer wall of the toilet stall, the inlet end of the airflow channel is connected to the outside of the toilet stall, and the outlet end of the airflow channel is connected to the inlet end of the heat conduction channel; the first fan is used to drive the gas flow within the airflow channel.

[0007] In the technical solution of this application embodiment, a person can perform excretion activities in the toilet and discharge the excrement into the receiving space through the toilet opening.

[0008] Because the heat collection plate is located outside the toilet, it can collect solar heat and transfer it to the air in the airflow channel formed between the heat collection plate and the outer wall of the toilet. Since the inlet of the airflow channel is connected to the outside of the toilet, and the outlet of the airflow channel is connected to the inlet of the heat conduction channel, the air that has absorbed heat can flow in the airflow path formed by the airflow channel and the heat conduction channel under the action of the first fan. When the hot air passes through the heat conduction channel, the heat in the hot air will be transferred to the containment space through the side wall of the heat conduction channel and the side wall of the collection and treatment device, thereby heating the excrement in the containment space to ensure that the microorganisms in the containment space are in a suitable temperature environment for normal decomposition of the excrement.

[0009] This heating method utilizes solar energy, a clean energy source, and does not require electricity. Therefore, it can reduce energy consumption, lower operating costs, and is cleaner and more environmentally friendly.

[0010] In some embodiments of this application, the ecological toilet also includes an exhaust duct and a negative pressure device. The exhaust duct is formed in the toilet room and is connected to the outlet end of the heat conduction duct. The outlet end of the exhaust duct is connected to the outside of the toilet room, and the negative pressure device is disposed at the outlet end of the exhaust duct.

[0011] This design creates negative pressure at the outlet of the ventilation channel, which facilitates the airflow in the heat conduction channel to flow out of the toilet through the ventilation channel.

[0012] In some embodiments of this application, the ecological toilet also includes a stirring device for stirring the excrement collected by the collection and treatment device.

[0013] This design allows the stirring device to facilitate microbial fermentation within the containment space.

[0014] In some embodiments of this application, the toilet wall has high-level ventilation holes; the ecological toilet also includes a ventilation channel, the inlet end of which is connected to the toilet and the outlet end of which is connected to the exhaust channel.

[0015] With this design, fresh air from outside the toilet can enter the toilet through the ventilation holes and then be exhausted into the exhaust duct through the ventilation channel, thereby achieving air exchange inside the toilet.

[0016] In some embodiments of this application, the outlet end of the ventilation duct is connected to the receiving space, and the receiving space is connected to the inlet end of the ventilation duct.

[0017] This design allows air from inside the toilet to enter the containment space through the ventilation duct. Since the containment space is connected to the ventilation duct, the air inside the containment space enters the ventilation duct and is then exhausted to the outside of the toilet. This not only achieves ventilation of the toilet but also accelerates the evaporation of liquid waste within the containment space, reducing the need for cleaning liquid waste.

[0018] In some embodiments of this application, the eco-toilet also includes a baffle and a drive mechanism. The baffle is disposed at the toilet opening, and the drive mechanism is used to move to drive the baffle to block or open the toilet opening.

[0019] With this design, when a person is using the toilet, the drive structure can be used to move the baffle to open the toilet opening for excretion. When excretion is not needed, the baffle can cover the toilet opening, preventing flies and other pests from entering the containment space through the opening. It can also isolate odors and prevent them from spreading into the toilet.

[0020] In some embodiments of this application, the eco-toilet also includes a pressure control switch connected to the drive mechanism, the pressure control switch being used to control the movement of the drive mechanism.

[0021] With this design, when the pressure control switch senses pressure, it can control the drive mechanism to open the toilet opening; when the pressure control switch does not sense pressure, the baffle will block the toilet opening. The pressure control switch and the drive mechanism are mechanically connected, making them more durable and energy-efficient.

[0022] In some embodiments of this application, the toilet includes a toilet seat, which is disposed in the toilet, such as a toilet opening formed on the toilet seat, the toilet seat having a seat ring, and a pressure control switch disposed on the seat ring.

[0023] With this setup, when a person sits on the seat, they press the pressure control switch, which controls the movement of the baffle to open the toilet opening, making the control quite convenient.

[0024] In some embodiments of this application, the toilet sidewall has ventilation holes; the toilet also includes a toilet seat, which is disposed in the toilet, such as the toilet opening being formed on the toilet seat; the toilet seat has a ventilation channel, the inlet end of the ventilation channel is connected to the toilet, the outlet end of the ventilation channel is located below the baffle and is connected to a connecting channel located below the baffle, and the connecting channel is connected to the ventilation channel.

[0025] With this design, even if the partition blocks the toilet entrance, fresh air from outside can still enter the toilet through the ventilation holes, then through the ventilation channel into the connecting channel below the partition, and finally into the exhaust duct. This ensures that the air in the connecting channel below the partition is clean, guaranteeing a better toilet experience next time.

[0026] In some embodiments of this application, the ecological toilet also includes a second fan, which is disposed at the connection between the connecting channel and the exhaust channel, and is located within the exhaust channel.

[0027] With this configuration, the second fan can draw air from outside the toilet into the toilet through the ventilation holes, and then allow the air to pass through the ventilation channel and connecting channel into the exhaust duct, thereby achieving ventilation and air exchange inside the toilet and replacing the air in the connecting channel. In addition, by installing a second fan, the airflow requirements in the exhaust duct can still be met when the negative pressure device is not working.

[0028] In some embodiments of this application, the ecological toilet also includes a negative pressure detection device electrically connected to the second fan. The negative pressure detection device is used to detect the working status of the negative pressure device in order to control the start and stop of the second fan.

[0029] With this setup, the negative pressure detection device can detect the working status of the negative pressure device. When the negative pressure device is not working, the second fan will work to meet the exhaust requirements of the exhaust channel.

[0030] In some embodiments of this application, the ecological toilet also includes a first check valve disposed on the ventilation channel.

[0031] With this design, the air in the ventilation channel can only flow unidirectionally from inside the toilet to the connecting channel, which can prevent the air in the connecting channel from flowing back into the toilet, thus ensuring that the air in the toilet is fresh.

[0032] In some embodiments of this application, the ecological toilet further includes a first reversing valve, the inlet end of which is connected to the outlet end of the heat conduction channel, the first outlet end of which is connected to the toilet chamber, and the second outlet end of which is connected to the ventilation channel.

[0033] With this configuration, when heating is needed inside the toilet (e.g., in winter), the first outlet of the first reversing valve is opened, allowing a portion of the hot airflow passing through the heat conduction channel to enter the toilet through the first outlet of the first reversing valve, thus providing a warmer airflow and heating the toilet environment. When heating is not needed (e.g., in summer), the first outlet of the first reversing valve is closed, and only the second outlet is opened, allowing the hot airflow passing through the heat conduction channel to enter the exhaust duct through the second outlet of the second reversing valve, and then discharged to the outside of the toilet, ensuring continuous heating of the excrement within the containment space.

[0034] In some embodiments of this application, the ecological toilet also includes a second check valve, which is disposed at the second outlet end of the first reversing valve.

[0035] With this configuration, when gas flows out from both the first and second outlets of the first reversing valve, the second check valve can prevent gas in the ventilation channel from flowing back into the toilet, ensuring fresh air in the toilet.

[0036] In some embodiments of this application, the eco-toilet also includes a human body sensor, which is installed in the toilet stall and electrically connected to the first reversing valve. The human body sensor is used to detect whether there is a person in the toilet stall, so as to control the first outlet end of the first reversing valve to connect or disconnect from the toilet stall.

[0037] With this setup, when the human body sensor detects someone in the toilet stall, it will automatically open the first outlet of the first reversing valve to introduce hot air from the heat conduction channel into the toilet stall to provide heating and ensure a better toilet experience for users.

[0038] In some embodiments of this application, the ecological toilet also includes a switch, which is disposed in the toilet stall and electrically connected to the first reversing valve, for controlling the connection or disconnection between the first outlet end of the first reversing valve and the toilet stall.

[0039] This setup allows users to operate a switch when needed, connecting the first outlet of the first reversing valve to the toilet stall. This allows hot air from the heat conduction channel to be introduced into the stall, providing heating and ensuring a comfortable experience. The switch allows for selective introduction of hot air based on individual needs.

[0040] In some embodiments of this application, the eco-toilet also includes a humidity sensor electrically connected to a first reversing valve. The humidity sensor is used to detect the humidity in the containment space in order to adjust the opening of the inlet end of the first reversing valve.

[0041] With this configuration, when the humidity sensor detects that the humidity in the containment space is too high, the opening of the inlet of the first reversing valve can be reduced to increase the flow rate of hot air in the airflow channel and the heat conduction channel, thereby increasing the evaporation rate of liquid excrement in the containment space, reducing the humidity in the containment space, slowing down the corrosion of moisture on the collection and treatment device, and extending the service life of the collection and treatment device.

[0042] In some embodiments of this application, the eco-toilet also includes a temperature sensor electrically connected to a first reversing valve. The temperature sensor is used to detect the temperature within the containment space in order to adjust the opening degree of the inlet end of the first reversing valve.

[0043] With this configuration, when the temperature sensor detects that the temperature in the containment space is too high, the opening of the inlet of the first reversing valve can be increased to reduce the flow rate of hot air in the airflow channel and the heat conduction channel, thereby reducing the efficiency of heat transfer from the heat conduction channel to the containment space, lowering the temperature in the containment space, and reducing the wear and tear on the collection and processing device.

[0044] In some embodiments of this application, the ecological toilet also includes a heat-conducting pipe, which is at least partially located inside the toilet stall. The inlet end of the heat-conducting pipe is connected to the outlet end of the airflow channel, and the outlet end of the heat-conducting pipe is connected to the inlet end of the heat-conducting channel.

[0045] With this design, hot air in the airflow channel can enter the heat-conducting pipe and then the heat-conducting channel. Since the heat-conducting pipe is located in the toilet, the heat from the air in the heat-conducting pipe can be conducted to the interior of the toilet, thus heating the toilet and providing a comfortable toilet environment.

[0046] In some embodiments of this application, the eco-toilet also includes a heating device disposed within a heat conduction channel.

[0047] With this configuration, the heating device can heat the air in the heat conduction channel, which can improve the heating efficiency and heating effect.

[0048] In some embodiments of this application, the top wall panel of the toilet is a semi-transparent panel.

[0049] This design can meet the lighting requirements of the toilet.

[0050] In some embodiments of this application, the outer wall surface of the heat collection plate is wavy.

[0051] This configuration can meet the light collection needs of the heat collection plate from multiple directions.

[0052] In some embodiments of this application, the number of heat conduction channels is at least two, and the at least two heat conduction channels include a first heat conduction channel and a second heat conduction channel. The first heat conduction channel passes through the receiving space, and the second heat conduction channel is disposed on the outer wall surface of the collection and processing device.

[0053] With this configuration, the first heat conduction channel can more effectively heat the excrement in the containment space, while the second heat conduction channel can heat and keep the collection and processing device warm.

[0054] In some embodiments of this application, the containment space includes two independent storage cavities, such as two toilet openings, with each storage cavity corresponding to one of the two toilet openings. The toilet openings are connected to their respective storage cavities, and the two storage cavities are used to contain solid excrement and liquid excrement, respectively. A first heat conduction channel is formed between the two storage cavities.

[0055] This design allows for the separate collection of solid and liquid waste, enabling the evaporation of liquid waste and the microbial treatment of solid waste. Furthermore, the first heat-conducting channel can simultaneously heat the waste in both storage chambers, thus ensuring both evaporation and heating requirements are met.

[0056] In some embodiments of this application, the sidewall of the first heat conduction channel serves as part of the sidewall of the two storage cavities.

[0057] This design allows for better heating of the excrement in both storage chambers, improving the heating effect.

[0058] In some embodiments of this application, the ecological toilet further includes a second reversing valve, the inlet end of which is connected to the outlet end of the airflow channel, and the inlet ends of the first heat conduction channel and the second heat conduction channel are respectively connected to the two outlet ends of the second reversing valve.

[0059] With this configuration, the gas in the airflow channel can be directed into the first heat conduction channel and the second heat conduction channel respectively using the second reversing valve.

[0060] In some embodiments of this application, the outer wall of the collection and processing device has a tank, and a second heat conduction channel is disposed in the tank and adapted to the tank.

[0061] This setup allows for the installation, maintenance, and replacement of the plate and the second heat conduction channel.

[0062] In some embodiments of this application, the eco-toilet also includes a photovoltaic panel, which is disposed outside the toilet and used for electrical connection with the eco-toilet's electrical devices.

[0063] This setup allows photovoltaic panels to collect solar energy for power generation, meeting the electricity needs of the eco-toilet's electrical equipment. Solar power is a clean energy source.

[0064] In some embodiments of this application, the toilet also has a cleaning passage communicating with the containment space.

[0065] This setup allows for the removal of excrement from the containment space via a squeezing channel.

[0066] In some embodiments of this application, the collection and treatment device is installed in at least one of the following ways: fully buried underground; partially buried underground; installed on the ground; when the collection and treatment device is installed in a partially buried and / or above-ground manner, the ecological toilet also includes a sealing plate for sealing the collection and treatment device; and / or, the ecological toilet also includes steps for reducing the height required to reach the collection and treatment device.

[0067] With this configuration, the collection and processing device in this application can be applied to different application scenarios.

[0068] In some embodiments of this application, the heat-conducting pipe also contains a heat-conducting medium for conducting heat based on the received thermal energy.

[0069] This design facilitates heat conduction. Attached Figure Description

[0092] The following is a detailed description of this application.

[0093] In related technologies, microbial decomposition technology can be used to decompose and process excrement inside toilets in a harmless manner.

[0094] However, in cold northern regions, outdoor temperatures are low, and outdoor toilets, especially dry toilets, are prone to freezing, which affects the decomposition of excrement by microorganisms. In arid regions lacking water sources, even though temperatures are higher, the lack of water makes exposed excrement a breeding ground for mosquitoes, eventually rendering toilets unusable and further impacting the ecological environment.

[0095] Although some existing toilet renovation projects have involved burying excrement storage tanks below the frost line to prevent freezing, this method involves a large amount of excavation and construction, and the walls of the excrement storage tanks also need to be thickened, which leads to high costs for toilet renovation. Furthermore, because the excrement storage tanks are located deep in the soil, the pressure is greater, which increases the risk of soil pollution and groundwater pollution.

[0096] Based on this, such as Figures 1-3 As shown, this application provides an ecological toilet 01, including a toilet stall 1, a collection and treatment device 2, a heat conduction channel a, a heat collection plate 3, and a first fan 4. The toilet stall 1 has a toilet opening. The collection and treatment device 2 has a receiving space b communicating with the toilet opening, the receiving space b being used to collect excrement discharged from the toilet opening and to perform microbial treatment.

[0097] A heat-conducting channel a is installed on the collection and processing device 2, and the outlet end of the heat-conducting channel a is connected to the outside of the toilet 1. A heat-collecting plate 3 is installed outside the toilet 1 and forms an airflow channel c with the outer wall of the toilet 1. The inlet end of the airflow channel c is connected to the outside of the toilet 1, and the outlet end of the airflow channel c is connected to the inlet end of the heat-conducting channel a. A first fan 4 is used to drive the gas flow in the airflow channel c.

[0098] It is understood that excrement can be decomposed by microorganisms within the containment space b, for example, by microorganisms into aerobic compost. Additionally, the heat collection plate 3 should be installed on the sunny side of the toilet 1 to meet its heat collection requirements. The heat collection plate 3 can be detachably connected to the toilet 1, facilitating its installation and removal, and allowing for adjustment of its position.

[0099] Optionally, in some examples, a stirring device may also be included, with the containment space b used to collect excrement discharged from the toilet opening and to carry out microbial fermentation treatment through the stirring device.

[0100] Optionally, in some examples, the heat collector 3 can also be connected to a power generation device, such as a wind power system, to collect heat demand through wind power.

[0101] For example, in an environment with large wind turbines generating electricity, the collector panel 3 can be connected to the wind turbines to directly collect wind power and generate heat. Alternatively, the collector panel 3 can be a dark-colored photovoltaic panel, which can collect both the electricity generated by solar energy and sunlight to generate heat. In areas with water sources, the collector panel can simultaneously collect heat and the electricity generated by the water, or directly decompose water through microorganisms; this application does not impose specific limitations.

[0102] Optionally, in some examples, the outlet end of the heat conduction channel a is connected to the interior of toilet 1 and the ventilation channel d via a first reversing valve 10.

[0103] In some examples, such as Figure 1 , Figure 2 As shown, a toilet stall 1 has an opening communicating with the interior of the toilet stall 1, and a door 11 is connected to the opening. The door 11 is used to open or close the opening to meet the user's toilet needs. The door 11 can be made of any material, such as metal, plastic, stone, wood, or rattan, and no specific limitation is made in this application.

[0104] In some examples, such as Figure 1 , Figure 2 As shown, a support platform 12 is also connected to the bottom of toilet 1, and the support platform 12 plays a supporting role.

[0105] The support platform 12 can be made of materials such as cement board or plastic board, and this application does not impose specific limitations. Specifically, the support platform 12 can also be stepped.

[0106] In some examples, the heat conduction channel a can be part of the collection and processing device 2. Alternatively, the heat conduction channel a can be a separate pipe that contacts the collection and processing device 2. The key is that the heat in the hot air within the heat conduction channel a can be conducted to the collection and processing device 2, and then to the excrement within the containment space b.

[0107] In some examples, such as Figure 1 , Figure 2 As shown, the eco-toilet 01 also includes a toilet seat 13 or a squat toilet installed inside the toilet stall 1, such as a toilet opening formed on the toilet seat 13 or squat toilet. The installation of the toilet seat 13 or squat toilet can improve the toilet experience.

[0108] In some examples, the first fan 4 can be located at the inlet end of the airflow channel c, which can better draw air from outside the toilet 1 into the airflow channel c. Of course, the first fan 4 can also be located in the middle of the airflow channel c.

[0109] Among them, the first fan 4 can be an axial flow fan.

[0110] The collection and processing device 2 is configured in at least one of the following ways:

[0111] Fully buried underground; partially buried underground; installed above ground;

[0112] When the collection and treatment device 2 is installed in a semi-buried and / or above-ground manner, the ecological toilet 01 also includes a sealing plate for sealing the collection and treatment device 2; and / or, the ecological toilet 01 also includes steps for reducing the height required to reach the collection and treatment device 2.

[0113] With the above setup, a person can defecate in toilet 1 and discharge the excrement into the receiving space b through the toilet opening. Since the heat collection plate 3 is located outside toilet 1, it can collect solar heat and transfer it to the air in the airflow channel c formed between the heat collection plate 3 and the outer wall of toilet 1. Because the inlet end of the airflow channel c is connected to the outside of toilet 1, and the outlet end of the airflow channel c is connected to the inlet end of the heat conduction channel a, and the outlet end of the heat conduction channel a is connected to the outside of toilet 1, the air that has absorbed heat can flow in the airflow path formed by the airflow channel c and the heat conduction channel a under the action of the first fan 4. When the hot air passes through the heat conduction channel a, the heat in the hot air will be transferred to the receiving space b through the side wall of the heat conduction channel a and the side wall of the collection and treatment device 2, thereby heating the excrement in the receiving space b to ensure that the microorganisms in the receiving space b are in a suitable temperature environment for normal decomposition of the excrement.

[0114] This heating method utilizes solar energy, a clean energy source, eliminating the need for electricity. This reduces energy consumption and operating costs, and is also cleaner and more environmentally friendly. Furthermore, solar energy can maintain the ambient temperature inside the eco-toilet 01 even in extremely cold conditions. If connected to electricity, the electrical energy can be converted into heat energy, or the eco-toilet 01 can be directly controlled by electricity.

[0115] The outlet of heat conduction channel a can be directly connected to the outside of toilet 1. Alternatively, other pipes can be installed at the outlet of heat conduction channel a to connect it to the outside of toilet 1. Details are as follows.

[0116] In some embodiments, such as Figure 2 , Figure 4 As shown, the ecological toilet 01 also includes an exhaust channel d and a negative pressure device 5. The exhaust channel d is formed in the toilet room 1 and is connected to the outlet end of the heat conduction channel a. The outlet end of the exhaust channel d is connected to the outside of the toilet room 1, and the negative pressure device 5 is installed at the outlet end of the exhaust channel d.

[0117] Among them, the air-drawing channel d can be set in the vertical direction, which can more fully guarantee the air-drawing effect of the air-drawing channel d.

[0118] Of course, the direction of extension of the air duct d can also be at an acute angle to the ground.

[0119] Alternatively, the ventilation duct d can be formed within the wall panel of toilet 1. Or, the ventilation duct d can also be a separate pipe.

[0120] With the above settings, the hot air in the airflow channel c can pass through the heat conduction channel a and then enter the exhaust channel d. Since a negative pressure is formed at the outlet of the exhaust channel d, the exhaust channel d can draw the air in the heat conduction channel a. This makes it easier for the airflow in the heat conduction channel a to flow out of the toilet 1 through the exhaust channel d, thereby ensuring continuous and stable heating of the collection and treatment device 2.

[0121] Based on this, in some embodiments, such as Figure 2 , Figure 4 As shown, the negative pressure device 5 includes a non-powered ventilation ball, which can rotate under the influence of airflow outside the toilet 1.

[0122] In some examples, the air extraction channel d is set vertically, and the rotation axis of the non-powered ventilation ball is also set vertically. This allows the non-powered ventilation ball to rotate better, thereby allowing the air in the air extraction channel d to flow out from the outlet end of the air extraction channel d more effectively.

[0123] With the above setup, the non-powered ventilation ball can rotate under the influence of airflow outside toilet 1, thereby creating negative pressure at the outlet of the ventilation channel d, allowing air inside the ventilation channel d to flow out from its outlet. Since the non-powered ventilation ball does not require electricity, energy consumption can be reduced.

[0124] Of course, in other embodiments, the negative pressure device 5 may also be a negative pressure exhaust fan.

[0125] The air inside toilet 1 is generally worse than the air outside toilet 1, so toilet 1 needs to be ventilated to ensure that the air inside toilet 1 is fresh.

[0126] Specifically, in some embodiments, such as Figure 2 , Figure 5 As shown, the toilet 1 has ventilation holes e on its side wall; the ecological toilet 01 also includes a ventilation channel f, the inlet end of which is connected to the toilet 1, and the outlet end of which is connected to the ventilation channel d.

[0127] The ventilation hole e is located at the top of toilet 1, which allows air from above to enter toilet 1 and also protects privacy.

[0128] In addition, the shape of the ventilation hole e can be a regular shape such as a circle or a regular shape. Alternatively, the ventilation hole e can also be an irregular shape.

[0129] In some examples, louvers can be installed inside the ventilation opening e to adjust the airflow direction from the ventilation opening e. The ventilation opening e can also be closed or opened by adjusting the louvers.

[0130] With the above setup, fresh air from outside toilet 1 can enter the toilet 1 through ventilation hole e, and then be discharged into exhaust duct d through ventilation channel f, thereby replacing the air inside toilet 1 and ensuring the cleanliness of the air inside toilet 1.

[0131] Based on this, in some embodiments, such as Figure 2 , Figure 6 As shown, the outlet end of the ventilation duct f is connected to the containment space b, and the containment space b is connected to the inlet end of the ventilation duct d.

[0132] In some examples, such as Figure 2 As shown, the ecological toilet 01 also includes a toilet seat 13, a ventilation channel f formed on the toilet seat 13, and a toilet opening formed on the toilet seat 13, with the toilet opening located on the ventilation path of the ventilation channel f. With this arrangement, air can enter the toilet 1 from outside through the ventilation hole e, then enter the ventilation channel f, pass through the toilet opening into the receiving space b, then enter the exhaust channel d, and finally be discharged to the outside of the toilet 1.

[0133] With the above configuration, fresh air from outside toilet 1 can enter the interior of toilet 1 through ventilation hole e, then enter the receiving space b through ventilation channel f and toilet opening, and then enter the exhaust channel d from the receiving space b, and finally be discharged to the outside of toilet 1. Since the air passes through the receiving space b, not only is ventilation of toilet 1 achieved, but the evaporation of liquid excrement in the receiving space b can also be accelerated, thereby reducing the need for cleaning excrement.

[0134] Of course, in other embodiments, the ventilation duct f may also be a separate pipe.

[0135] In some embodiments, such as Figure 7 As shown, the ecological toilet 01 also includes a baffle 6 and a drive mechanism 7. The baffle 6 is located at the toilet opening, and the drive mechanism 7 is used to move to drive the baffle 6 to block or open the toilet opening.

[0136] In some examples, there are two toilet openings: one for solid waste and one for liquid waste. A baffle 6 is positioned at the solid waste opening to control its opening or closing.

[0137] Of course, baffle 6 can also open or close both toilet openings at the same time.

[0138] The drive mechanism 7 can be a guide rod drive mechanism 7, a gear drive mechanism 7, or a motor drive mechanism 7, etc.

[0139] With the above setup, when a person is using the toilet, the drive structure can be used to move the baffle 6 to open the toilet opening and then perform excretion. When excretion is not required, the baffle 6 can cover the toilet opening, preventing flies and other pests from entering the containment space b through the toilet opening. It can also isolate odors and prevent odors from spreading into the toilet 1.

[0140] Based on this, in some embodiments, the ecological toilet 01 also includes a pressure control switch that is connected to the drive mechanism 7 for transmission, and the pressure control switch is used to control the movement of the drive mechanism 7.

[0141] It is understandable that a pressure control switch is a component that can drive the drive mechanism 7 to move when pressed.

[0142] With the above configuration, when the pressure control switch senses pressure, it can control the drive mechanism 7 to move and open the toilet opening. After the pressure disappears, the pressure control switch rebounds, thereby controlling the baffle 6 to move and close the toilet opening. Since the pressure control switch and the drive mechanism 7 are mechanically connected, it is relatively durable and does not consume electricity.

[0143] The pressure control switch can be located in various positions, such as on the bottom or side of toilet 1, or on the seat of toilet 13 inside toilet 1. Details are as follows.

[0144] In some embodiments, such as Figure 7 As shown, toilet 1 includes a toilet seat 13, which is provided in toilet 1. For example, the toilet opening is formed on the toilet seat 13, and the toilet seat 13 has a seat ring. A pressure control switch is provided on the seat ring.

[0145] The seat ring material can include expanded polypropylene (Epp) plastic foam, which makes the seat ring easier to clean and more skin-friendly and comfortable.

[0146] With the above setup, when a person sits on the seat, their weight acts on the pressure control switch, causing it to depress and open the toilet opening by moving the baffle 6. When the person finishes using the toilet and stands up, the weight on the pressure control switch disappears, causing it to spring back up and close the toilet opening by moving the baffle 6. Controlling the pressure control switch through the person's toilet movements is quite convenient.

[0147] In some embodiments, such as Figure 7As shown, the toilet 1 has a ventilation hole e on its side wall; the toilet 1 also includes a toilet seat 13, which is installed in the toilet 1, such as the toilet opening being formed on the toilet seat 13; the toilet seat 13 has a ventilation channel j, the inlet end of the ventilation channel j is connected to the toilet 1, the outlet end of the ventilation channel j is located below the baffle 6, and is connected to the connecting channel g located below the baffle 6, and the connecting channel g is connected to the ventilation channel d.

[0148] It should be explained that the toilet 13 has a toilet passage, the toilet opening is located in the passage of the toilet passage, and the connecting passage g is part of the toilet passage.

[0149] The ventilation channel j can be formed on the rear side of the toilet bowl 13.

[0150] In some examples, the connecting channel g can be connected to the containment space b, and the containment space b can be connected to the ventilation channel d, thereby achieving the connection between the connecting channel g and the ventilation channel d.

[0151] Alternatively, it can be installed in the connecting pipe, which connects the connecting pipe and the exhaust pipe.

[0152] With the above setup, even if the baffle 6 blocks the toilet opening, air from outside the toilet 1 can still enter the toilet 1 through the ventilation hole e, and then enter the connecting channel g below the baffle 6 through the ventilation channel j. Since the connecting channel g is connected to the exhaust channel d, the air will continue to enter the exhaust channel d and eventually be discharged from the outlet end of the exhaust channel d. This ensures that the air in the connecting channel g is clean, ensuring that the air in the space below the baffle 6 inside the toilet 13 is clean, and ensuring the next toilet experience.

[0153] In some embodiments, such as Figure 7 As shown, the ecological toilet 01 also includes a second fan 8, which is located at the connection between the connecting channel g and the ventilation channel d, and is located inside the ventilation channel d.

[0154] The second fan 8 has two functions: first, it draws air from inside toilet 1 into the connecting channel g, and then into the exhaust channel d; second, it exhausts the air in the exhaust channel d to the outside of the exhaust channel d.

[0155] With the above configuration, the second fan 8 can draw air from outside the toilet 1 into the toilet 1 through the ventilation hole e, and then allow the air to pass through the ventilation channel j and the connecting channel g into the exhaust channel d, thereby ensuring the ventilation effect. In addition, by setting up the second fan 8, even when the negative pressure device 5 is not working, the second fan 8 can still meet the airflow requirements in the exhaust channel d.

[0156] Based on this, in some embodiments, the ecological toilet 01 also includes a negative pressure detection device, which is electrically connected to the second fan 8. The negative pressure detection device is used to detect the working status of the negative pressure device 5 in order to control the start and stop of the second fan 8.

[0157] In some examples, the negative pressure device 5 is a non-powered ventilation ball, and the negative pressure detection device is a speed detection device. The speed detection device is used to detect the speed of the non-powered ventilation ball. When the speed detection device detects that the non-powered ventilation ball has no speed (generally occurs in windless weather outside toilet 1, such as cloudy days), the speed detection device controls the second fan 8 to start, so as to ventilate the room and the connecting passage g, and at the same time drive the airflow in the exhaust passage d to promote the flow of hot air in the heat conduction passage a, so as to meet the heating needs of the excrement in the containment space b.

[0158] In other examples, the negative pressure device 5 is a negative pressure exhaust fan. The negative pressure detection device is electrically connected to the negative pressure exhaust fan. When the negative pressure detection device detects that the negative pressure exhaust fan is not working, it controls the second fan 8 to start, so as to ventilate the room and the connecting passage g. At the same time, it drives the airflow in the exhaust passage d to promote the flow of hot air in the heat conduction passage a, so as to meet the heating requirements of the excrement in the containment space b.

[0159] With the above settings, the negative pressure detection device can detect the working status of the negative pressure device 5. When the negative pressure device 5 fails to generate negative pressure at the outlet end of the exhaust channel d, the second fan 8 is controlled to start to ventilate the room and the connecting channel g. At the same time, the airflow in the exhaust channel d is driven to promote the flow of hot air in the heat conduction channel a, so as to meet the heating requirements of the excrement in the containment space b.

[0160] In some embodiments, such as Figure 7 As shown, the ecological toilet 01 also includes a first check valve 9, which is located on the ventilation channel j.

[0161] Understandably, the first check valve 9 is used to prevent air from flowing back into the toilet 1 from the connecting passage g.

[0162] The first check valve 9 can be installed at the inlet, middle or outlet of the venting channel j.

[0163] With the first check valve 9 in place, the air in the ventilation channel j can only flow unidirectionally from the inside of the toilet 1 to the connecting channel g. This prevents the air in the connecting channel g from flowing back into the toilet 1, thus ensuring that the air inside the toilet 1 is fresh.

[0164] In some cold regions, the temperature inside toilet stall 1 is low. In order to provide a comfortable toilet environment in cold conditions, this application can also raise the temperature inside toilet stall 1 by heating it. The details are as follows.

[0165] In some embodiments, such as Figure 2 , Figure 8 As shown, the ecological toilet 01 also includes a first reversing valve 10. The inlet end of the first reversing valve 10 is connected to the outlet end of the heat conduction channel a, the first outlet end of the first reversing valve 10 is connected to the toilet room 1, and the second outlet end of the first reversing valve 10 is connected to the ventilation channel d.

[0166] The first directional valve 10 can be a three-way valve.

[0167] In this way, when heating is needed inside toilet 1 (e.g., in winter), the first outlet of the first reversing valve 10 is opened, allowing a portion of the hot airflow passing through the heat conduction channel a to enter toilet 1 through the first outlet of the first reversing valve 10, thereby providing a warmer airflow inside toilet 1 and heating it to create a warm toilet environment. When heating is not needed inside toilet 1 (e.g., in summer), the first outlet of the first reversing valve 10 is closed, and only the second outlet of the first reversing valve 10 is opened, allowing the hot airflow passing through the heat conduction channel a to enter the exhaust channel d through the second outlet of the second reversing valve 103, and then exhaust it to the outside of toilet 1, ensuring continuous heating of the excrement in the receiving space b.

[0168] In some embodiments, such as Figure 8 As shown, the ecological toilet 01 also includes a second check valve 101, which is located at the second outlet end of the first reversing valve 10.

[0169] It is understandable that the second check valve 101 exists to prevent the airflow in the air-pulling channel d from flowing back from the second outlet of the first reversing valve 10 to the inlet of the first reversing valve 10, and then flowing into the toilet 1 through the first outlet of the first reversing valve 10, so as to prevent the air in the air-pulling channel d from polluting the air in the toilet 1, especially when the air-pulling channel d is connected to the receiving space b.

[0170] With the above configuration, the second check valve 101 is present to prevent the airflow in the air-pulling channel d from flowing back from the second outlet of the first reversing valve 10 to the inlet of the first reversing valve 10, and then flowing back into the toilet 1 through the first outlet of the first reversing valve 10. This is to prevent the air in the air-pulling channel d from polluting the air in the toilet 1 and to ensure that the air in the toilet 1 is fresh. In particular, when the air-pulling channel d is connected to the receiving space b, the air in the air-pulling channel d will become polluted due to the influence of the receiving space b. Therefore, the configuration of the second check valve 101 is even more important.

[0171] In some embodiments, the eco-toilet 01 further includes a human body sensor, which is disposed in the toilet compartment 1 and electrically connected to the first reversing valve 10. The human body sensor is used to detect whether there is a person in the toilet compartment 1, so as to control the first outlet end of the first reversing valve 10 to connect or disconnect from the toilet compartment 1.

[0172] With the above settings, when the human body sensor detects someone in toilet stall 1, it will automatically open the first outlet of the first reversing valve 10 to introduce hot air from the heat conduction channel a into the toilet stall 1 to heat the interior of toilet stall 1, thereby ensuring the toilet user's experience. When no one is in toilet stall 1, the first outlet of the first reversing valve 10 will close, and the hot air from the heat conduction channel a will completely enter the exhaust channel d through the second outlet of the first reversing valve 10 to continuously heat the containment space b.

[0173] Based on this, in some embodiments, the ecological toilet 01 also includes a switch, which is disposed in the toilet compartment 1 and electrically connected to the first reversing valve 10, for controlling the connection or disconnection between the first outlet end of the first reversing valve 10 and the toilet compartment 1.

[0174] The switch can be installed inside or outside toilet 1.

[0175] In addition, the switch can be a push-button type or a pull-button type, etc.

[0176] With the above setup, when a person needs to use the toilet, they can operate the switch to connect the first outlet of the first reversing valve 10 to the inside of the toilet stall 1, thereby introducing hot air from the heat conduction channel a into the toilet stall 1 to heat the interior and ensure a comfortable toilet experience. By controlling the switch, hot air can be selectively introduced into the toilet stall 1 according to the user's needs, thus better meeting their usage requirements.

[0177] For example, in summer, there is no need to supply hot air into toilet 1, so there is no need to operate the switch. In winter, however, if hot air needs to be supplied into toilet 1, then the switch is operated to control the first outlet of the first reversing valve 10 to connect with the inside of toilet 1.

[0178] In some embodiments, the eco-toilet 01 further includes a humidity sensor electrically connected to the first reversing valve 10. The humidity sensor is used to detect the humidity in the containment space b in order to adjust the opening degree of the inlet end of the first reversing valve 10.

[0179] The humidity sensor can be installed inside the containment space b to detect the humidity inside the containment space b.

[0180] With the above settings, when the humidity sensor detects that the humidity in the containment space b is too high, the opening of the inlet end of the first reversing valve 10 can be reduced to increase the flow rate of hot air in the airflow channel c and the heat conduction channel a, thereby increasing the evaporation rate of liquid excrement in the containment space b, reducing the humidity in the containment space b, slowing down the corrosion of moisture on the collection and processing device 2, and extending the service life of the collection and processing device 2.

[0181] In some embodiments, the eco-toilet 01 further includes a temperature sensor electrically connected to the first reversing valve 10. The temperature sensor is used to detect the temperature within the containment space b in order to adjust the opening degree of the inlet end of the first reversing valve 10.

[0182] The temperature sensor can be installed inside the containment space b to detect the temperature inside the containment space b.

[0183] With the above settings, when the temperature sensor detects that the temperature in the containment space b is too high, the opening of the inlet end of the first reversing valve 10 can be increased to reduce the flow rate of hot air in the airflow channel c and the heat conduction channel a, thereby reducing the efficiency of heat transfer from the heat conduction channel a to the containment space b, reducing the temperature in the containment space b, and reducing the wear and tear of the collection and processing device 2 and its internal packing.

[0184] In other embodiments, such as Figure 9 As shown, the ecological toilet 01 also includes a heat conduction pipe h, which is at least partially located inside the toilet room 1. The inlet end of the heat conduction pipe h is connected to the outlet end of the airflow channel c, and the outlet end of the heat conduction pipe h is connected to the inlet end of the heat conduction channel a.

[0185] It is understandable that the heat-conducting pipe h is made of a heat-conducting material, such as aluminum, copper, or thermally conductive silicone, etc.

[0186] With the above setup, the hot air in the airflow channel c can enter the heat-conducting pipe h, and then enter the heat-conducting channel a. Since the heat-conducting pipe h is located in toilet 1 and can conduct heat, the heat of the air in the heat-conducting pipe h can be conducted to the interior of toilet 1, thus heating toilet 1 and providing a comfortable toilet environment.

[0187] In some embodiments, the heat-conducting pipe h may contain a heat-conducting medium. The heat-conducting medium may completely or partially fill the heat-conducting pipe h, supplying heat to the ecological toilet 01 through the heat-conducting medium. Since the heat-conducting medium has a better heat transfer effect than air, it can significantly improve the heat transfer efficiency. The heat-conducting medium may be hot oil or a two-phase medium.

[0188] Specifically, the two-phase medium can be low-viscosity silicone oil or ethylene glycol-water mixture (antifreeze type), which can be circulated with a magnetic pump to better avoid low-temperature solidification.

[0189] In some embodiments, an integrated plate heat exchanger may also be included to improve the heat exchange efficiency between the two-phase medium and the reaction zone. Heat pipes are embedded in key areas to utilize phase change for rapid heat homogenization.

[0190] The phase change thermal energy storage base (PCM) can be made of paraffin-based materials (phase change temperature 0-5℃) or salt hydrate materials and encapsulated in an aluminum honeycomb structure base.

[0191] In some embodiments, layered thermal storage can also be designed: the upper layer rapidly absorbs heat during the day, while the lower layer slowly releases heat at night, extending the insulation time. A graphene coating is combined to enhance thermal conductivity and improve the heat storage / release rate.

[0192] In some embodiments, intelligent temperature control and system integration can be constructed by combining the heat conduction pipe h. For example, an adaptive control algorithm can be introduced to dynamically adjust the power of the electric heating tape based on a PID controller, and preheating can be combined with weather forecasts. IoT remote monitoring can also be introduced: temperature and power data can be transmitted in real time via 5G / 4G / LoRa modules, supporting remote intervention.

[0193] In some embodiments, for waste heat recovery from exhaust gas: a heat exchanger can be installed in the exhaust pipe to preheat the cold air entering the system. The reaction chamber adopts a double-layer stainless steel vacuum structure to reduce heat loss.

[0194] In some embodiments, such as Figure 9 As shown, the ecological toilet 01 also includes a heating device 102, which is installed in the heat conduction channel a.

[0195] The heating device 102 can be an electric heating wire or a silicone rubber heating sheet.

[0196] By installing a heating device 102 in the heat conduction channel a, the heating device 102 can also heat the air in the heat conduction channel a. In this way, there are two heating methods: electric heating and hot air heating. This can improve the heating efficiency of the air and improve the heating effect, making it more suitable for some cold regions.

[0197] In some embodiments, such as Figure 10 The number of heat conduction channels a is at least two, and the at least two heat conduction channels a include a first heat conduction channel a1 and a second heat conduction channel a2. The first heat conduction channel a1 passes through the receiving space b, and the second heat conduction channel a2 is disposed on the outer wall surface of the collection and processing device 2.

[0198] Among them, the second heat conduction channel a2 is a pipe with heat conduction capability.

[0199] In addition, the second heat conduction channel a2 can be attached to the outer wall of the collection and treatment device 2, so as to better heat the excrement inside the collection and treatment device 2.

[0200] With the above configuration, since the first heat-conducting channel a1 passes through the receiving space b, it can more effectively heat the excrement within the receiving space b. Meanwhile, since the second heat-conducting channel a2 is located on the outer wall of the receiving and processing device 2, it can heat and maintain the temperature of the collection and processing device 2. The cooperation of the first heat-conducting channel a1 and the second heat-conducting channel a2 achieves a more effective heating of the excrement within the receiving space b.

[0201] In some embodiments, such as Figure 2 As shown, the containment space b includes two independent storage cavities, such as two toilet openings. The two storage cavities correspond one-to-one with the two toilet openings, and the toilet openings are connected to the corresponding storage cavities. The two storage cavities are used to contain solid excrement and liquid excrement, respectively. A first heat conduction channel a1 is formed between the two storage cavities.

[0202] For ease of description, we define two storage cavities as a first storage cavity b1 and a second storage cavity b2, and two toilet openings as a first toilet opening and a second toilet opening. The first toilet opening is connected to the first storage cavity b1, and the second toilet opening is connected to the second storage cavity b2. Solid excrement can enter the first storage cavity b1 through the first toilet opening, and liquid excrement can enter the second storage cavity b2 through the second toilet opening.

[0203] For example, when the ecological toilet 01 includes a baffle 6 and a drive mechanism 7, the baffle 6 is disposed at the first toilet opening to block or close the first toilet opening.

[0204] In some examples, only the solid waste in the first storage chamber b1 is subjected to microbial decomposition, while the liquid waste in the second storage chamber b2 is subjected to evaporation.

[0205] In some examples, such as Figure 2 As shown, the first storage cavity b1 and the second storage cavity b2 are arranged in a vertical direction, and the first storage cavity b1 is located above the second storage cavity b2.

[0206] With the above configuration, during toilet use, solid waste can enter the first storage chamber b1 through the first toilet opening, while liquid waste can enter the second storage chamber b2 through the second toilet opening. This achieves separate collection of solid and liquid waste, allowing for evaporation of liquid waste and microbial treatment of solid waste. This results in greater cleanliness and hygiene. Furthermore, since the first heat-conducting channel a1 is located between the first and second storage chambers b1 and b2, the waste in both chambers can be heated simultaneously, ensuring both evaporation and heating requirements are met.

[0207] In some embodiments, the sidewall of the first heat-conducting channel a1 serves as part of the sidewall of the two storage cavities. This allows the hot air within the heat-conducting channel a to be closer to the storage cavities, enabling better heating of the excrement within both storage cavities and improving the heating effect.

[0208] In some embodiments, such as Figure 10 As shown, the ecological toilet 01 also includes a second reversing valve 103. The inlet end of the second reversing valve 103 is connected to the outlet end of the airflow channel c. The inlet end of the first heat conduction channel a1 and the inlet end of the second heat conduction channel a2 are respectively connected to the two outlet ends of the second reversing valve 103.

[0209] The second directional valve 103 can be a three-way valve.

[0210] In this way, the airflow from the outlet end of the airflow channel c can flow to the first heat conduction channel a1 and the second heat conduction channel a2 simultaneously through the second reversing valve 103, thereby providing hot air to the first heat conduction channel a1 and the second heat conduction channel a2 at the same time, so as to meet the heating requirements of the first heat conduction channel a1 and the second heat conduction channel a2 for the excrement in the containment space b.

[0211] In some embodiments, the outer wall of the collection and processing device 2 has a tank, and a second heat conduction channel a2 is disposed in the tank and adapted to the tank.

[0212] In some examples, the second heat conduction channel a2 can be detachably snapped into the groove, which facilitates the installation and removal of the second heat conduction channel a2.

[0213] The above setup allows for the installation, maintenance, and replacement of the plate and the second heat conduction channel a2.

[0214] In some embodiments, such as Figure 7 As shown, the ecological toilet 01 also includes accessory equipment 104 installed in the toilet room 1. The accessory equipment 104 includes at least one of lighting 1041, shelf 1042, and handrail 1043.

[0215] The lighting 1041 can be connected to the ceiling of the toilet 1, and the shelf 1042 and the handrail 1043 can be connected to the side wall of the toilet 1.

[0216] With the above settings, the lighting lamp 1041 can meet the lighting needs, the shelf 1042 can meet the needs of placing items such as mobile phones and toilet paper, and the handrail 1043 can meet the needs of gripping. By setting up accessory equipment 104, the overall convenience of the ecological toilet 01 is improved.

[0217] In some embodiments, toilet 1 includes an inner body and an insulation panel covering the outside of the body. In this way, the body can provide a supporting effect, and the insulation panel can provide a heat preservation effect.

[0218] The main body can be made of color steel plate, and the insulation board can be made of wood-plastic composite board.

[0219] In some embodiments, the top wall panel of toilet 1 is a semi-transparent panel. In this way, not only can the privacy requirements of toilet 1 be met, but the lighting requirements of toilet 1 can also be met.

[0220] Among them, the translucent plate can be a double-layer translucent high-density polyethylene (HDPE) diffuser.

[0221] In some embodiments, the outer wall surface of the heat collection plate 3 is corrugated. In this way, the heat collection plate 3 can meet the light collection needs from multiple directions. For example, the heat collection plate 3 can absorb direct sunlight, reflected light from the ground, or reflected light from snow, thereby improving the heat collection efficiency of the heat collection plate 3.

[0222] In some embodiments, electric heating can be used in low-temperature areas with a minimum temperature of -10 to 0°C. The heat collection plate 3 is used to collect solar energy, which powers the battery. When heating is required, electrical energy is extracted to heat the heating wire, thereby ensuring that the internal temperature reaches the reaction requirements.

[0223] In some embodiments, the solar collector plate may have a reserved electrical interface, which can supply power to the system when environmental conditions permit.

[0224] In some embodiments, designs can also be made for adaptability to extreme environments, such as antifreeze and self-maintenance mechanisms, such as using pipeline electric heating tape + intelligent temperature control, which automatically activates the antifreeze mode when the temperature drops below 2°C.

[0225] In some embodiments, the collector plate may be equipped with a self-cleaning function, such as an integrated vibration motor or a hydrophobic coating, to prevent snow / ice accumulation.

[0226] In some embodiments, critical components (such as pumps and controllers) are equipped with dual-machine hot standby, automatically switching in case of failure, and quick-release pipe interfaces for easy and rapid replacement of damaged modules.

[0227] In some embodiments, the heating device can be adapted to scenarios such as greenhouse soil heating and oil pipeline heat tracing, and the temperature threshold can be adjusted. It can also be expanded into a regional microgrid node to supply power to other devices.

[0228] In some embodiments, vehicle-mounted devices can also be developed for temporary heating in polar scientific expeditions or disaster relief, thus the use of the ecological toilet proposed in this application can better protect the ecological environment.

[0229] In some embodiments, the ecological toilet system proposed in this application features an emergency shutdown triggered by the pressure / leakage sensor of the media circulation system under emergency conditions. The electric heating system includes overcurrent protection and grounding fault detection, meeting IP67 protection standards. Aerospace-grade sealing materials are used, withstanding temperature differences of -40 to 120°C. A self-diagnostic system periodically checks component lifespan and provides early warnings for replacement.

[0230] With the continuous development of technology, machine learning can be used to predict energy consumption curves and dynamically adjust energy storage / consumption strategies. Adding carbon nanotubes / alumina nanoparticles to the heat transfer medium can increase thermal conductivity by more than 20%. Exploring laser charging or microwave power supply can achieve contactless emergency energy replenishment.

[0231] Through the above solution, the Eco-Toilet 01 can stably maintain a reaction temperature of 5~25℃ in extreme environments of -30℃, improving overall energy efficiency by more than 40%, while also possessing adaptability to multiple scenarios and high reliability. The next step is recommended to verify the design through digital twin simulation and conduct small-scale field tests to optimize parameters.

[0232] In some embodiments, the ecological toilet 01 further includes a stirring device, which is at least partially located within the containment space b, for stirring the excrement within the containment space b.

[0233] The stirring device can be a manual stirring device, which does not require electricity and can be operated manually to stir the excrement in the containment space b, so that the excrement and microorganisms are fully mixed, ensuring the quality and efficiency of decomposition. The manual stirring device can save energy.

[0234] Alternatively, the mixing device can be an automatic mixing device that uses sensors to automatically mix the excrement in the receiving space b after use, ensuring that the excrement is fully mixed with microorganisms, thus guaranteeing decomposition quality and efficiency. Automatic mixing devices are more convenient.

[0235] By setting up a stirring device, the excrement can be stirred to fully mix with microorganisms, thereby ensuring a full reaction between the microorganisms and the excrement, and making the reaction between the microorganisms and the excrement highly efficient.

[0236] In some embodiments, such as Figure 1 , Figure 2 As shown, the ecological toilet 01 also includes a photovoltaic panel 105, which is installed outside the toilet 1 and is used to electrically connect to the electrical devices of the ecological toilet 01.

[0237] The electrical devices may include a lighting lamp 1041, a first fan 4, a second fan 8, a drive mechanism 7, a first reversing valve 10, a second reversing valve 103, and a heating device 102, etc.

[0238] In addition, the photovoltaic panel 105 and the heat collector 3 can be installed on the same outer wall of the toilet 1, so that the photovoltaic panel 105 and the heat collector 3 are both facing the sun, thereby meeting the light needs of both at the same time.

[0239] By setting up photovoltaic panels 105, solar energy can be collected and used to generate electricity to meet the power needs of the electrical devices in the ecological toilet 01. Solar power generation is a clean energy source.

[0240] In some embodiments, such as Figure 1 As shown, toilet 1 also has a cleaning passage i that connects to the containment space b. By setting up the cleaning passage i, cleaning personnel can clean the excrement in the containment space b through the cleaning passage i.

[0241] In the case where the containment space b includes a first storage cavity b1 and a second storage cavity b2, the scouring channel i is connected to the first storage cavity b1.

[0242] Additionally, a cover plate can be installed at the cleaning channel i to close or open the cleaning channel i. The cleaning channel i can be opened when cleaning is needed and closed when cleaning is not needed.

[0243] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
