Description

Technical Field

[0001] This invention belongs to the field of ecological toilet technology, and specifically relates to a modular assembled ecological toilet. Background Technology

[0002] Ecological toilets refer to environmentally friendly toilets that do not pollute the environment, fully utilize various resources, and emphasize the concepts and functions of pollutant self-purification and resource recycling. The core idea of ​​developing ecological toilets is to use safe, economical, and reliable methods to ensure that water resources and nutrients operate in a closed-loop cycle within human society and economic development, thereby protecting and conserving limited water resources while simultaneously realizing the resource utilization of nutrients. Common technical features include odorless operation, waterless flushing, zero pollution discharge, water conservation, and waste resource utilization.

[0003] Currently, the main types of eco-toilets on the market include earth-built composting eco-toilets, dry-packed eco-toilets, and a small number of prefabricated eco-toilets. Earth-built composting eco-toilets rely on on-site fermentation chambers to achieve on-site composting and degradation of feces and sewage; dry-packed eco-toilets use biodegradable plastic bags to seal and collect excrement, which is then transported and disposed of in a unified manner; prefabricated eco-toilets are prefabricated modularly produced, transported to the site for assembly, and equipped with internal fecal and urine collection or simple treatment units. They mostly rely on continuous ventilation systems to alleviate odor problems inside the chamber, and the toilet bowl typically has a normally open channel structure at the bottom.

[0004] Among the technical solutions for various existing ecological toilets mentioned above: Civil engineering composting ecological toilets have long construction cycles, fixed and non-relocatable facilities, and are difficult to reuse; dry-packed toilets cannot achieve on-site resource utilization of excrement, and continuous transportation increases maintenance costs; existing prefabricated ecological toilets generally lack effective sealing mechanisms for the toilet opening, leaving the squat toilet opening open for extended periods, allowing odors from the fermentation chamber to easily flow upwards and mosquitoes to enter the toilet along the passageway; at the same time, most products integrate the toilet shell with the sewage treatment unit, making it difficult to separate, transport, and independently repair the functional units, and unable to flexibly combine and allocate modules according to on-site traffic flow, making it difficult to adapt to the requirements of rapid deployment, relocation, and on-site resource utilization in scenarios such as scenic spots, remote villages, and temporary work sites. Summary of the Invention

[0005] The purpose of this invention is to provide a modular assembled ecological toilet, which solves the technical problems of existing civil engineering ecological toilets that cannot be relocated, dry packaged toilets that cannot be recycled locally, conventional prefabricated toilets with open toilet passages that easily cause backflow of odors and mosquitoes, the integration of the whole and the treatment unit that makes it difficult to disassemble and maintain, and the inability to adapt to the rapid disassembly and reuse of the toilet in the field, rural areas, construction sites and other scenarios without pipe networks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A modular ecological toilet includes assembled walls; the bottom of the assembled walls is connected by a metal frame, which is made of horizontal and vertical I-beams spliced ​​together. The bottom of the metal frame is equipped with high support legs, and the upper part of the metal frame is laid with a carrier plate. The high support legs support the overall structure, so that the bottom of the ecological toilet forms an operating mezzanine space. A second partition is set in the middle of the rectangular space, which divides the overall space into two independent toilet areas on the left and right. Multiple first partitions are arranged at equal intervals in each independent area, and the first partitions divide a single space into multiple independent toilet cubicles. The carrier plate has a groove corresponding to the installation position of each toilet stall. An outer plate is embedded in the groove and the outer plate is overlapped and fixed to the metal frame. A squat toilet is fixedly installed in the middle of the outer plate. The squat toilet is equipped with an arc-shaped partition inside, which divides the inner cavity of the toilet into a urine collection chamber and a feces collection chamber. A first discharge outlet is opened at the bottom depression of the feces collection chamber, and a second discharge outlet is opened at the bottom depression of the urine collection chamber. A urine collection pipeline assembly is installed in the bottom working interlayer space formed by the high support legs and connected to the second discharge port; a baffle that can rotate around the axis is installed on the lower end face of the first discharge port.

[0007] Furthermore, the urine collection pipeline assembly includes a sewage pipe; the lower end of the second discharge port is connected to the sewage pipe, the sewage pipe adopts a multi-segment bending structure, and the pipeline is provided with at least one V-shaped bend. Each of the aforementioned sewage pipes is connected to a tee pipe at its lower end. A guide pipe is installed at the interface of the tee pipe. The sewage pipes are interconnected through the guide pipe, and the urine generated in each compartment is collected into the guide pipe.

[0008] Furthermore, the bottom of the outer plate is rotatably assembled with a shaft via a fixed connecting rod; the side of the baffle near the shaft is integrally fixed with a connecting part, and the baffle is rigidly fixed to the shaft via the connecting part; a connecting plate is fixedly assembled at the end of the shaft away from the connecting part.

[0009] Furthermore, the angle between the baffle and the connecting part is 45°, and the angle between the baffle and the connecting plate is 90°. During the 90° rotation of the connecting plate around the shaft, the baffle simultaneously completes a 90° flip, switching from a horizontal closed posture to a vertical open posture.

[0010] Furthermore, a long strip groove is provided on the connecting plate; a U-shaped connector is slidably assembled inside the groove; a push rod is fixedly connected to the end of the connector away from the groove; when the push rod makes horizontal reciprocating linear motion, the connector slides along the inside of the groove, and simultaneously pushes the connecting plate to deflect around the shaft as the rotation center.

[0011] Furthermore, a hollow cylinder is horizontally installed on the lower surface of the outer plate via a connecting rod; a piston is slidably assembled inside the cylinder, and the end of the push rod away from the connector extends through the side wall of the cylinder into the cylinder and is fixedly connected to the piston.

[0012] Furthermore, a thrust spring is installed inside the cylinder on the side opposite to the push rod. The thrust spring continuously applies an elastic thrust to the piston in the direction close to the push rod. When the piston is not subjected to external forces other than the spring, the thrust spring, through the push rod and connecting rod, links the baffle to keep the baffle in a closed state that blocks the first discharge port.

[0013] Furthermore, a recessed groove is formed on the upper surface of the outer plate corresponding to the area where the person using the toilet stands and steps; a pedal that can reciprocate and rise and fall in the vertical direction is installed inside the recessed groove; a rectangular spring is installed at the bottom of the pedal; a bladder is fixedly connected to the bottom of the pedal, and the lower end of the bladder is sealed to the bottom surface of the recessed groove, and the bladder forms a sealed airtight cavity and completely covers the rectangular spring.

[0014] Furthermore, the airtight cavity enclosed by the bladder skin is filled with air as the transmission medium; the air pipe is fixed at the installation position of the sinking groove at the bottom of the outer plate, one end of the air pipe is connected to the inside of the airtight cavity, and the other end of the air pipe is connected to the chamber between the piston and the push rod inside the cylinder.

[0015] Furthermore, the outer peripheral edge of the pedal can be sealed to the upper surface of the outer plate through a bladder.

[0016] The beneficial effects of this invention are: 1. The present invention adopts a prefabricated modular structure in the factory. The walls, supports, partitions and carrier plates can be quickly assembled on site. The whole can be hoisted and transported and reused. Each functional unit can be disassembled, inspected and replaced individually. The toilet stalls can be flexibly increased or decreased according to the flow of people on site. It overcomes the defects of traditional civil engineering ecological toilets, such as long construction cycle, fixed and non-relocatable, and high cost of repeated construction. It is suitable for rapid deployment in various scenarios such as scenic spots, remote villages and temporary construction sites without municipal pipe networks.

[0017] 2. This invention incorporates an arc-shaped partition inside the squat toilet to achieve physical separation of feces and urine, allowing for separate and independent collection of feces and urine. Feces can be fermented and composted on-site, diluted, and returned to the fields, realizing closed-loop resource utilization of excrement. This addresses the shortcomings of dry-packed toilets, which can only collect excrement in a sealed manner, resulting in high maintenance costs due to long-term external transportation of excrement and the inability to recycle resources. The urine pipeline is designed with a V-shaped bend to form a water seal structure, which can independently prevent odors from rising into the compartment and significantly reduce the energy consumption of ventilation equipment.

[0018] 3. This invention features a pneumatically driven, flip-up baffle at the discharge outlet. When no one is using the toilet, the baffle horizontally closes the channel, preventing the backflow of odor from the fermentation chamber and the entry of mosquitoes into the toilet along the channel. This solves the problems of existing prefabricated toilets where the bottom opening is always open, resulting in strong odors and a poor toilet experience. It can maintain a odor-free cubicle without the need for high-power continuous ventilation.

[0019] 4. This invention adopts a purely mechanical transmission structure with a foot pedal airbag linkage rod, which does not require electrical components for power supply. The baffle can be automatically opened and closed by human foot pedaling. It can operate stably in outdoor environments without power supply and in low temperature and humid environments. The linkage slide groove is equipped with a stroke compensation structure, which can offset the errors in the processing and assembly of parts, avoid the mechanism from jamming, and has a low overall failure rate and less frequency of maintenance.

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Please see Figures 1-4 As shown, a modular ecological toilet includes a rectangular usable space enclosed by assembled walls 100. The bottom of the assembled walls 100 is connected by a metal frame 300, which is spliced ​​from horizontal and vertical I-beams and fixed by welding at each junction. High support legs 200 are installed at the bottom of the metal frame 300, and a carrier plate 400 is laid on the top of the metal frame 300. The high support legs 200 support the overall structure, so that the bottom of the ecological toilet forms a working mezzanine space for the placement of sewage collection equipment and independent operation and maintenance. A second partition 600 is set in the middle of the rectangular space, dividing the overall space into two independent toilet areas on the left and right. Multiple first partitions 500 are equidistantly arranged in each independent area, and the first partitions 500 divide a single space into multiple independent toilet cubicles.

[0024] This invention adopts a fully modular assembly structure. The components such as the wall 100, high support legs 200, carrier plate 400, and partition plate 202 can all be prefabricated in the factory. On-site assembly only requires simple bolting and welding. The whole can be hoisted, moved, and reused, solving the defects of traditional civil engineering composting ecological toilets that cannot be relocated and have high costs for repeated construction. The bottom mezzanine space independently arranges the manure collection components. Each functional module can be disassembled for inspection, maintenance, and replacement. The number of partition modules can be increased or decreased according to the flow of people on site, adapting to the needs of rapid deployment and flexible allocation in scenarios without municipal pipeline networks, such as scenic spots, remote villages, and temporary construction sites.

[0025] Please refer to it again. Figure 3 , Figure 5 , Figure 6 as well as Figure 7As shown, specifically, the carrier plate 400 has grooves corresponding to the installation positions of each toilet stall, and the outer plate 1 is embedded in the groove. The outer plate 1 is overlapped and fixed on the metal frame 300, which makes the assembly process simple and the on-site assembly efficiency high. The squat toilet 2 is fixedly installed in the middle of the outer plate 1. The squat toilet 2 is provided with an arc-shaped partition 202 inside. The arc-shaped partition 202 divides the inner cavity of the toilet bowl 201 into a urine collection chamber and a feces collection chamber. A first discharge port 203 that runs vertically through the bottom of the feces collection chamber is opened, and a second discharge port 204 that is arc-shaped at the top and circular at the bottom of the urine collection chamber is opened.

[0026] The arc-shaped partition 202 achieves physical separation of feces and urine, allowing for separate and independent collection of feces and urine. After separation and collection, feces and urine can be composted on-site or diluted and returned to the field, thus fully realizing the resource recycling of excrement. This overcomes the technical shortcomings of existing dry-packed toilets, which can only be sealed for collection, cannot be recycled on-site, and require long-term external transportation, which significantly increases operation and maintenance costs.

[0027] Within the bottom working mezzanine space supported by the high support legs 200, a feces collection bucket is arranged directly below each first discharge port 203, which can directly receive the feces falling through the first discharge port 203. The collection structure is simple and the operation of picking up and cleaning is convenient.

[0028] Please refer to it again. Figure 4 As shown, a urine collection pipeline assembly is installed in the bottom working layer. The pipeline layout is as follows: the lower end of the second discharge port 204 connects to the sewage pipe 18. The sewage pipe 18 adopts a multi-segment bending structure, with at least one V-shaped bend. The V-shaped water seal structure blocks the upward flow of gas inside the sewage pipe 18, preventing odors from escaping upwards to the toilet stalls and optimizing the toilet user experience. The lower end of each sewage pipe 18 connects to a T-connector 19. A guide pipe 20 is installed at the interface of the T-connector 19. The sewage pipes 18 are interconnected through the guide pipe 20, collecting the urine generated in each stall into the guide pipe 20. In actual application, urine collection buckets can be placed at both ends of the guide pipe 20 to complete the centralized collection of urine, simplifying operation and maintenance.

[0029] Please refer to it again. Figure 7 , Figure 8 , Figure 9 as well as Figure 10 As shown, in some preferred embodiments, the lower end face of the first discharge port 203 is equipped with a baffle 3 that can rotate around a pivot. When no one is using the toilet, the baffle 3 completely covers and seals the first discharge port 203, which on the one hand prevents the odor generated by the fecal fermentation chamber from overflowing upward through the first discharge port 203, thus improving the internal environment of the cubicle, and on the other hand, covers the collection bucket below, improving the overall visual appeal. When someone is using the toilet, the baffle 3 removes its cover from the first discharge port 203, and the feces can fall vertically down the first discharge port 203 into the feces collection bucket below.

[0030] Addressing the pain points of existing prefabricated ecological toilets, such as the toilet bowl opening being open for extended periods, odor from the fermentation chamber, easy entry of mosquitoes and other insects into the toilet room via the passageway, high energy consumption for ventilation and deodorization, and poor toilet experience, this invention features an automatically closing baffle 3 that completely seals the excretion passage when not in use. This prevents odor backflow and mosquitoes from climbing up from the source, significantly reducing the operating load of the ventilation system, achieving a odor-free cubicle, and significantly improving user comfort.

[0031] To achieve stable opening and closing of the baffle 3, this invention is equipped with a complete pneumatic connecting plate 7 transmission mechanism, the specific assembly structure of which is as follows: The bottom of the outer plate 1 is rotatably mounted with a shaft 6 via a fixed connecting rod; the side of the baffle 3 near the shaft 6 is integrally fixed with a connecting part 5, and the baffle 3 is rigidly fixed to the shaft 6 via the connecting part 5; a connecting plate 7 is fixedly mounted at the end of the shaft 6 away from the connecting part 5. During equipment operation, external force drives the connecting plate 7 to rotate around the shaft 6 as the center, and the shaft 6 synchronously drives the connecting part 5 to deflect, ultimately achieving synchronous flipping of the baffle 3, completing the opening and closing of the discharge port. (Refer to...) Figure 11 As shown, the angle between baffle 3 and connecting part 5 is 45°, and the angle between baffle 3 and connecting plate 7 is 90°. During the 90° rotation of connecting plate 7 around point M, baffle 3 simultaneously completes a 90° flip, as shown. Figure 10 As shown, the switch from a horizontal closed posture to a vertical open posture is performed in the same way in the reverse direction.

[0032] The connecting plate 7, shaft 6, and connecting part 5 form a fixed-angle transmission pair. Only a small step of the pedal 4 is needed to drive the baffle 3 to complete a full 90° opening. The mechanical transmission structure is stable with no dead points, the transmission angle is accurately matched, the stepping resistance is small, and the user experience is comfortable. The entire pure mechanical linkage structure does not contain electronic components, is suitable for low temperature and humid harsh environments in the wild, has a low failure rate, and reduces the investment in later maintenance.

[0033] A long strip groove 8 is opened on the connecting plate 7; a U-shaped connector 9 is slidably assembled inside the groove 8; a push rod 10 is fixedly connected to the end of the connector 9 away from the groove 8. When the push rod 10 makes horizontal reciprocating linear motion, the connector 9 can slide along the inside of the groove 8, and simultaneously push the connecting plate 7 to deflect around the shaft 6 (i.e. point M) as the rotation center.

[0034] A hollow cylinder 11 is horizontally installed on the lower surface of the outer plate 1 via a connecting rod; a piston 13 is slidably assembled inside the cylinder 11, and the end of the push rod 10 away from the connector 9 extends through the side wall of the cylinder 11 into the cylinder and is fixedly connected to the piston 13; a thrust spring 12 is assembled inside the cylinder 11 on the side away from the push rod 10, and the thrust spring 12 continuously applies an elastic thrust to the piston 13 in the direction close to the push rod 10. When the piston 13 is not subjected to external force other than the spring, the thrust spring 12 can be linked to the baffle 3 through the push rod 10 and the connecting rod, so that the baffle 3 can continuously maintain the closed state of blocking the first discharge port 203.

[0035] A recessed groove 14 is provided on the upper surface of the outer plate 1 corresponding to the area where the user stands and steps. A pedal 4 that can be raised and lowered vertically is installed inside the recessed groove 14. A rectangular spring 16 is installed at the bottom of the pedal 4. The rectangular spring 16 supports the pedal 4 upward under normal conditions, so that the pedal 4 remains in an elevated state when there is no external force. A bladder 15 is fixedly connected to the bottom of the pedal 4. The lower end of the bladder 15 is sealed to the bottom surface of the recessed groove 14. The bladder 15 forms a sealed airtight cavity and completely covers the rectangular spring 16, which protects the rectangular spring 16, reduces the corrosion of dirt and moisture, and extends the service life of the spring. The airtight cavity formed by the bladder 15 is filled with air as a transmission medium. An air pipe 17 is fixed at the bottom of the outer plate 1 corresponding to the installation position of the recessed groove 14. One end of the air pipe 17 is connected to the inside of the airtight cavity, and the other end of the air pipe 17 is connected to the chamber between the piston 13 and the push rod 10 inside the cylinder 11. In actual use, when a person steps down on the pedal 4, the pedal 4 compresses the bladder 15 to compress the volume of the airtight chamber. The air in the airtight chamber is compressed and then enters the cylinder 11 through the air pipe 17. The gas pressure pushes the piston 13 to slide to the bottom of the cylinder 11. The piston 13 simultaneously drives the push rod 10 to move horizontally. The push rod 10 drives the connecting rod to deflect through the connector 9. Finally, the linkage baffle 3 flips to open the first discharge port 203, realizing the function of automatically opening the first discharge port 203 when someone uses the toilet.

[0036] This mechanism uses an airbag to pneumatically transmit pedaling power. The pedal 4 only needs to be pressed down slightly to output stable air pressure to drive the entire linkage mechanism. There is no need for manual lifting or electrical control. It is purely human-driven and can be used normally in all weather conditions in the field where there is no power supply. The bladder 15 completely covers the rectangular spring 16, which isolates it from the corrosion of feces and sewage, extends the service life of the spring and the transmission mechanism of the pedal 4, and reduces the frequency and cost of later maintenance.

[0037] Furthermore, the outer periphery of the pedal 4 can be sealed to the upper surface of the outer plate 1 via the bladder 15 (not shown in the attached figure), completely sealing the opening of the sinking groove 14. This eliminates the risk of step collision and improves safety, while also preventing debris and sewage from falling into the sinking groove 14, avoiding mechanism jamming and further ensuring the long-term stable operation of the entire pneumatic linkage sealing mechanism.
