Abstract
Description
Technical Field
[0001] This invention relates to the field of sanitary ware technology, and in particular to a waterless, fully automatic, portable, liftable toilet. Background Technology
[0002] Traditional flush toilets rely on fixed municipal water supply and sewage networks and can only be installed and used in well-equipped fixed buildings. With the development of outdoor travel, underground space development, engineering operations, emergency rescue and disaster relief, and special vehicles, the number of scenarios without sewage pipes is increasing, which puts forward practical needs for toilet facilities in non-fixed scenarios, such as lightweight deployment, hygienic operation and maintenance, and multi-scenario adaptability.
[0003] Existing toilets have three main limitations: First, they lack portability, as most are integrated fixed structures that are bulky and heavy, making them inconvenient to move and deploy quickly. Second, they lack a continuous cylindrical waste bag automatic packing function, requiring manual cleaning of waste, which can easily spread odors, pose hygiene risks, and result in low maintenance efficiency. Third, they have poor adaptability to different scenarios, failing to meet the needs of use in basements without drainage pipes, temporary facilities, campervans, RVs, motorhomes, special vehicles, trucks, and other vehicle-mounted scenarios, as well as temporary settlements in disaster areas.
[0004] In summary, existing toilet products have significant shortcomings in terms of structural form, waste treatment methods, and adaptability to various scenarios, and cannot simultaneously meet the needs of portable deployment, hygienic waste treatment, and various waterless scenarios. Summary of the Invention
[0005] The purpose of this invention is to provide a waterless, fully automatic, portable, and liftable toilet, thereby solving the technical problem that existing toilets cannot simultaneously meet the needs of portable deployment, hygienic waste disposal, and various waterless usage scenarios.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0024] The present invention provides a waterless fully automatic packaging portable lifting toilet, including an outer shell 1, a stool guide 2, a conveying mechanism 3, a heat sealing and melting mechanism 4, a control unit 5, and a pull-out box 6. The stool guide 2 is installed in the upper region of the outer shell 1, and an annular receiving cavity 7 is provided between the outer wall of the stool guide 2 and the inner wall of the outer shell 1. The annular receiving cavity 7 is used to accommodate a rolled continuous cylindrical stool collection bag. The conveying mechanism 3 is installed inside the outer shell 1 and located below the stool guide body 2. The conveying mechanism 3 is used to convey the continuous cylindrical stool collection bag in the annular receiving cavity 7 from top to bottom along the inner wall of the stool guide body 2. The heat-sealing and melting mechanism 4 is installed inside the outer shell 1 and located below the conveying mechanism 3. The heat-sealing and melting mechanism 4 is used to heat-seal and melt the continuous cylindrical waste collection bag that has been conveyed to the position, forming an independently sealed waste collection bag. The pull-out box 6 can be pulled out and inserted into the lower part of the outer shell 1 and is located below the heat-sealing and melting mechanism 4. The pull-out box 6 is used to hold the waste collection bag. The control unit 5 is installed on the outer wall of the outer casing 1, and the conveying mechanism 3 and the heat-sealing and fusion mechanism 4 are both electrically connected to the control unit 5. The waterless fully automatic packaging portable lifting toilet provided by the present invention integrates the functions of guiding feces, bag conveying, heat sealing and fusion, and waste collection into the outer casing 1. The overall structure is compact, does not rely on fixed municipal water supply and sewage pipe networks, and can be placed and used directly without complicated installation procedures. The whole machine is easy to transport and transfer, and can meet the requirements of temporary deployment and rapid withdrawal. It effectively solves the defects of traditional toilets in terms of insufficient portability and difficulty in flexible deployment. The continuous cylindrical feces collection bag is contained in the annular receiving cavity 7. The conveying mechanism 3 automatically conveys the bag down the inner wall of the guiding body 2, and then the heat sealing and fusion mechanism 4 simultaneously completes the heat sealing and fusion, automatically forming an independent sealed waste collection bag. The waste is contained entirely within a sealed bag, eliminating the need for manual contact with the waste and collection container during cleaning. This effectively prevents odor spread and cross-contamination, significantly improving hygiene while reducing manual maintenance and increasing waste disposal efficiency. The waterless, sealed storage system completely eliminates reliance on sewer pipes and water supply systems. The pull-out box allows for easy removal and transport of the sealed waste bag without the need for pipe network connections. The product can be directly applied to fixed and temporary scenarios such as basements and construction site facilities without sewer pipes, and is compatible with mobile scenarios such as campervans, RVs, motorhomes, special vehicles, and trucks. It also meets the rapid deployment needs of emergency scenarios such as temporary shelters in disaster areas and emergency refuge sites, greatly expanding the applicability of toilet facilities in piped environments.
[0025] As an optional implementation, a support plate 11 is provided inside the outer shell 1, the guide body 2 is installed at the upper end of the support plate 11, and the conveying mechanism 3 is installed at the lower end of the support plate 11. An elliptical opening 111 is provided in the middle of the support plate 11. An inlet groove 112 extends upward from the inner wall of the elliptical opening 111. Two inlet grooves 112 are symmetrically arranged to facilitate the smooth entry of the two sides of the continuous cylindrical stool collection bag into the double roller group 35. This allows the double roller group 35 to easily convey the continuous cylindrical stool collection bag downward when it rolls. An arc-shaped plate 113 extends downward from the inner wall of the elliptical opening 111. Two arc-shaped plates 113 are symmetrically arranged to form a circumferential limit and guide for the downward continuous cylindrical stool collection bag, so that the bag maintains an extended cylindrical shape when entering the heat sealing and cutting station, thereby improving the stability of conveying and sealing.
[0026] As an optional implementation, the conveying mechanism 3 includes a first motor 31, a first transmission structure 32, a first gear transmission group 33, a second gear transmission group 34, and a double roller group 35. The first motor 31 is connected to the first transmission structure 32, and the control unit 5 is electrically connected to the first motor 31 to control the operation of the first motor 31. The two ends of the first transmission structure 32 are respectively meshed with the first gear transmission group 33 and the second gear transmission group 34 to realize the synchronous linkage of the two gear transmission groups. The outer shell of the first motor 31 is connected to the outer wall of the first gear transmission group 33. The outer walls of both the first gear transmission group 33 and the second gear transmission group 34 are connected to the support plate 11. A double roller group 35 is connected to each opposite side of the first gear transmission group 33 and the second gear transmission group 34. The two double roller groups 35 are arranged opposite each other and form a bag clamping and conveying gap. There are two inlet slots 112. The double roller group 35 and the inlet slots 112 are set one to one. The continuous cylindrical stool collection bag is smoothly guided by the inlet slots 112 and then enters the clamping and conveying area of the double roller group 35.
[0027] A single first motor 31, paired with a first transmission structure 32, synchronously drives the first gear transmission group 33 and the second gear transmission group 34, thereby driving two double roller groups 35 to rotate synchronously at the same speed. This ensures uniform force on both sides of the continuous cylindrical stool collection bag and consistent conveying speed, effectively avoiding problems such as wrinkles, deviations, and jamming caused by asynchronous conveying. The friction conveying method using double roller clamping provides stable conveying traction through clamping force, adapting to continuous cylindrical stool collection bags of different materials and thicknesses. It also avoids damage caused by sharp components contacting the bag, ensuring conveying accuracy while reducing bag wear and improving the long-term reliability of the equipment. The drive, transmission, and execution components are integrated and assembled on the lower end face of the support plate 11, making full use of the internal space under the guide body 2. The overall structure is compact, meeting the design requirements of miniaturization and lightweight portable toilets. At the same time, the guide groove 112 and the double roller group 35 correspond one-to-one to form a continuous guide path. When the bag is loaded, it can be smoothly inserted into the gap between the rollers along the guide groove 112, reducing the difficulty of bag changing and assembly.
[0028] As an optional implementation, both the first gear transmission group 33 and the second gear transmission group 34 include a housing 331, a fixed shaft 332, a first mating gear 333, a movable shaft 334, a second mating gear 335, and an adjusting structure 336. The two ends of the fixed shaft 332 are rotatably connected to the two side walls of the housing 331. Each side wall of the housing 331 is provided with a strip-shaped opening 3311. The two ends of the movable shaft 334 pass through the two strip-shaped openings 3311, and the movable shaft 334 can slide along the length of the strip-shaped openings 3311 and rotate around its own axis. The first mating gear 333 and the second mating gear 334... Both gear 35 and adjustment structure 336 are located inside housing 331. First mating gear 333 is mated and connected to fixed shaft 332, and second mating gear 335 is mated and connected to movable shaft 334. One end of adjustment structure 336 is rotatably connected to movable shaft 334, and the other end of adjustment structure 336 is rotatably connected to housing 331. First mating gear 333 can mesh with second mating gear 335. Adjustment structure 336 is used to apply pre-tightening thrust to movable shaft 334 so that second mating gear 335 always maintains meshing with first mating gear 333, and synchronously drives corresponding rollers to maintain clamping force on bag body. The double roller assembly 35 includes a first roller 351 and a second roller 352. The first roller 351 is connected to the extended end of the fixed shaft 332, and the second roller 352 is connected to the extended end of the movable shaft 334. There is a bag clamping and conveying gap between the first roller 351 and the second roller 352. When the continuous cylindrical stool collection bag is initially placed into the bag clamping and conveying gap, the second roller 352 needs to be pressed, which will cause the movable shaft 334 to slide along the length direction of the strip-shaped opening 3311, thereby increasing the bag clamping and conveying gap between the first roller 351 and the second roller 352, making it easier for the end of the continuous cylindrical stool collection bag to pass through. After the external force is released, under the action of the counter-pushing elastic force of the adjusting structure 336, the movable shaft 334 drives the second roller 352 and the second mating gear 335 to reset, so that the second mating gear 335 and the first mating gear 333 remain in a meshing state, and the size of the bag clamping and conveying gap returns to its original state.
[0029] As an optional implementation, the adjustment structure 336 includes a support frame 3361, a torsion spring 3362, and a rotary shaft. One end of the support frame 3361 is rotatably connected to the movable shaft 334, and the other end of the support frame 3361 is rotatably connected to the housing 331 via the rotary shaft, forming a swing force transmission structure with the rotary shaft as the fulcrum. The torsion spring 3362 is sleeved on the rotary shaft, with one end of the torsion spring 3362 abutting against the side wall of the movable shaft 334 and the other end of the torsion spring 3362 abutting against the inner wall of the support frame 3361. The torsion spring 3362 is used to provide an elastic preload torque. The support frame 3361 pushes the movable shaft 334 to translate along the strip-shaped opening 3311 toward the fixed shaft 332, so that the second mating gear 335 is always pressed and meshed with the first mating gear 333, and simultaneously maintains the clamping and conveying force of the double roller group 35 on the bag body.
[0030] The first motor 31 has a first output gear 311 on its output shaft. The first transmission structure 32 includes a first double gear 321, a long connecting shaft 322, a second double gear 323, and a short connecting shaft 324. There are two of each of the first double gear 321, the second double gear 323, and the short connecting shaft 324. The two first double gears 321 are connected to both ends of the long connecting shaft 322. The second double gear 323 and the short connecting shaft 324 are connected in a one-to-one correspondence. The short connecting shaft 324 is rotatably connected to the corresponding housing 331. The two ends of the long connecting shaft 322 are rotatably connected to the two housings 331, so as to synchronously transmit power to the gear transmission groups on both sides. The first output gear 311 is meshed with one of the first double gears 321. The first double gear 321 is meshed with the corresponding second double gear 323. The second double gear 323 is meshed with the corresponding first mating gear 333. The first output gear 311, a first double gear 321, a second double gear 323, and a short connecting shaft 324 are all located within the housing 331 of the first gear transmission group 33; the other first double gear 321, the other second double gear 323, and the other short connecting shaft 324 are all located within the housing 331 of the second gear transmission group 34.
[0031] The transmission meshing relationship is as follows: the first output gear 311 meshes with the first double gear 321 of the first gear transmission group 33; the first double gear 321 of each group meshes with the second double gear 323 on the same side; the second double gear 323 of each group meshes with the first mating gear 333 on the same side, and the first mating gear 333 meshes with the second mating gear 335 on the same side, forming a multi-stage reduction transmission link. Through the cross-transmission of a single first motor 31 and a long connecting shaft 322, the power is synchronously distributed to the gear transmission groups on both sides, ensuring that the speed and rotation angle of the two double roller groups 35 are completely consistent, avoiding wrinkles, deviation, and jamming of the continuous cylindrical waste collection bag due to the difference in conveying speed on both sides, ensuring that the bag body descends smoothly in a flat and smooth cylindrical shape, and providing a stable working position foundation for the subsequent heat sealing and melting process.
[0032] As an optional implementation, the heat-sealing and melting mechanism 4 includes a second motor 41, a second transmission structure 42, a lead screw structure 43, a fixed pressure-bearing mold 44, and a movable heat-sealing mold 45. The outer shell of the second motor 41 is connected to the support plate 11, and the second motor 41 is connected to the middle of the second transmission structure 42. There are two lead screw structures 43, which are symmetrically arranged and both are connected to the outer shell 1. The two ends of the second transmission structure 42 are respectively connected to the two lead screw structures 43 to realize synchronous power distribution from a single power source to both sides. The two ends of the movable heat-sealing mold 45 are respectively connected to the sliders of the two lead screw structures 43. The fixed pressure-bearing mold 44 is connected to the outer shell 1 and is arranged opposite to the movable heat-sealing mold 45. The movable heat-sealing mold 45 can move towards or away from the fixed pressure-bearing mold 44 to complete the mold closing and opening actions. The movable heat-sealing mold 45 has a strip-shaped groove on its mold-closing end face, and the two end faces of the strip-shaped groove form the heat-sealing working surface; the fixed pressure mold 44 has a strip-shaped protrusion on its mold-closing end face, which can connect with the strip-shaped groove and melt the continuous cylindrical waste collection bag; in the mold-closing state, the heat-sealing working surface and the end face of the fixed pressure mold clamp the bag body to complete the heat sealing, while the strip-shaped protrusion is embedded in the strip-shaped groove, forming a shearing action on the bag body between the two heat-sealing lines to complete the melting, and simultaneously forming the bottom seal of the upper bag body and the opening seal of the lower waste collection bag.
[0033] The movable heat-sealing mold 45 is equipped with a heating element and a temperature control detection device. The heating element is used to heat the heat-sealing working surface so that the bag film melts and adheres. The temperature control detection device is used to collect the temperature signal of the heat-sealing working surface in real time and feed it back to the control unit 5 to realize closed-loop control of the heat-sealing temperature.
[0034] As an optional implementation, the heat-sealing and melting mechanism 4 also includes two position detection elements 46, located at opposite ends of a lead screw structure 43. The position detection elements 46 detect the two extreme movement positions of the slider. Both the position detection elements 46 and the second motor 41 are electrically connected to the control unit 5. Based on the position signal fed back by the position detection elements 46, the control unit 5 controls the start, stop, and forward / reverse rotation of the second motor 41, achieving precise control of the mold closing and opening strokes. The position detection elements 46 feed back the position signal to the control unit 5 in real time, automatically completing the logical control of the start, stop, and direction switching of the second motor 41 without manual intervention. Combined with the conveying mechanism 3 and the heat-sealing and melting mechanism 4, this achieves fully automated execution of the entire process from bag conveying to heat sealing and melting, reducing the operational threshold and aligning with the product positioning of fully automated packaging.
[0035] As an optional implementation, the control unit 5 is equipped with an operation button group, a display screen, and a voice broadcast element; the operation button group is used to input control commands such as automatic packaging and manual bag conveying, the display screen is used to display parameters such as equipment operating status, remaining power, and heat sealing temperature in real time, and the voice broadcast element is used to output operation guidance, operating status prompts, and fault alarm information, and supports switching between Chinese and English voice.
[0036] The outer casing 1 also houses an energy storage power supply and an external power supply interface. The energy storage power supply can use a 12V lithium battery pack, providing DC power to the entire unit in scenarios where no external power supply is available. The external power supply interface is equipped with a power adapter, allowing connection to an external 220V AC power source. After conversion, the AC power supply powers the entire unit and simultaneously charges the energy storage power supply. The device supports automatic switching between two operating modes: built-in energy storage power supply and external AC power supply. A retractable handle 12 is located on the front wall panel of the outer casing 1. The handle 12 can be extended or retracted, either fully retracting into the storage slot on the front wall panel of the outer casing 1 or extending outwards to create a gripping space for handling and relocation of the entire unit.
[0037] As an optional implementation, an annular seat ring 21 extends outward from the upper end of the guide body 2, and an annular support ring 22 extends outward from the lower end of the guide body 2. An annular receiving cavity 7 is formed between the lower end of the annular seat ring 21, the upper end of the annular support ring 22, the outer wall of the guide body 2, and the inner wall of the outer shell 1. An annular opening of the annular receiving cavity 7 is formed between the outer periphery of the annular seat ring 21 and the inner wall of the outer shell 1. The annular receiving cavity 7 adopts a top annular opening for material filling. When replacing the roll of continuous cylindrical waste collection bag, there is no need to disassemble the entire machine structure. The continuous cylindrical waste collection bag can be directly inserted into the cavity along the annular opening. The operation steps are simple and the learning threshold is low. Consumables can be replenished quickly, which is suitable for outdoor travel, emergency rescue, temporary construction sites, and other usage scenarios that require frequent replacement of consumables and rapid maintenance.
[0038] As an optional implementation, the outer casing 1 includes a movable shell 13, a fixed shell 14, telescopic column assemblies 15, an adjustment assembly 16, and a movable cover 17. Four sets of telescopic column assemblies 15 are vertically arranged. The movable shell 13 and the fixed shell 14 are connected through these four sets of telescopic column assemblies 15, and the movable shell 13 can move up and down relative to the fixed shell 14. The adjustment assembly 16 is mounted on the movable shell 13 and is used to lock the lifting position of the telescopic column assemblies 15, thereby limiting the relative height between the movable shell 13 and the fixed shell 14. The movable cover 17 is hinged to the upper end of the movable shell 13 and can cover the port of the movable shell 13. The relative lifting of the movable shell 13 and the fixed shell 14 via the telescopic column assemblies 15 allows for flexible adjustment of the overall seat height of the toilet, accommodating the sitting posture needs of users of different heights and meeting the height restrictions of different spaces such as RVs, basements, and temporary locations. During storage and transportation, the height can be lowered to the minimum, effectively reducing the overall vertical volume of the unit, improving the convenience of handling and storage, and enhancing the product's portability.
[0039] The waterless, fully automatic, portable, lifting toilet of this invention requires no water to clean during use. A special bactericidal and deodorizing coagulant can be placed inside the continuous cylindrical waste collection bag, so that urine can be turned into a solid through the special bactericidal and deodorizing coagulant.
