[0004] To achieve the above object, the utility model adopts the following technical scheme:

[0005] The utility model provides a kind of circular spiral heating coil composite structure device for incineration toilet, including toilet body, the top side of the toilet body is integrally formed with toilet backrest, the inside of the toilet body is provided with excretion cavity, the side of the toilet body is provided with collection cavity, the collection cavity is below excretion cavity and is communicated with excretion cavity, the inside of the toilet body is provided with circular spiral heating coil body, the circular spiral heating coil body includes shell, nichrome inner layer, ceramic insulating layer middle layer and aluminium alloy shell outer layer, the nichrome inner layer is used for generating heat energy using high-density winding mode, the thickness of the ceramic insulating layer middle layer is 1-2mm, for electrical insulation and thermal isolation, the aluminium alloy shell outer layer adopts thin-wall design, and the thickness is 2-3mm, for protection and heat dissipation, the shell is located inside the collection cavity.

[0006] In a possible design, a waste box is placed inside the collection cavity, an induction coil is arranged inside the waste box, the induction coil is connected to both ends of the circular spiral heating coil body, and is powered by a 36V DC power supply; the toilet body is provided with wires and a power connector; the induction coil is connected to the power connector via the wires, and the wires have good high-temperature resistance and insulation.

[0007] In a possible design, the circular spiral heating coil body has a circular spiral shape as a whole, and is designed as a six-turn spiral structure; the distance between each turn is 5mm, the diameter is 5cm, and the wavelength range is between 30cm and 50cm.

[0008] In a possible design, the nichrome inner layer is composed of multiple high-temperature-resistant alloy wires, the ceramic insulating layer middle layer is composed of sheet-shaped ceramics, and the aluminium alloy shell outer layer is formed by stamping and welding of aluminium alloy sheet material.

[0009] In a possible design, the shell of the circular spiral heating coil body is fixedly connected to a connecting seat, and the connecting seat is fixedly connected to a connecting point between the toilet inner liner; a ventilation pipe connection port is fixedly connected to one side of the shell of the circular spiral heating coil body, the ventilation pipe connection port is used to introduce combustion-supporting air to assist incineration of excrement, and the ventilation pipe connection port is in communication with a ventilation pipe; and the components cooperate to realize efficient and safe incineration.

[0010] In a possible design, the toilet backrest is provided with a placing cavity inside, the top of the toilet backrest is provided with a sealing plate, the sealing plate is used to block the placing cavity, and the inside of the sealing plate is provided with a taking hole.

[0011] In one possible design, a fixed base is fixedly connected to the top side of the toilet body, and a rotating shaft is fixedly passed through the interior of the fixed base. A toilet seat and a toilet ring are rotatably fitted on the outer wall of the rotating shaft, with the toilet ring located below the toilet seat.

[0012] In one possible design, a plurality of cushioning pads are fixedly connected to the top of the toilet body, the cushioning pads being located below the toilet seat and used in conjunction with the toilet seat.

[0013] In this application, the nickel-chromium alloy inner layer is formed by tightly winding multiple strands of high-temperature resistant, high-conductivity alloy filaments according to a pre-set spiral path, with each filament tightly connected to form a cylindrical heating core structure. The ceramic insulation layer is made by cutting, grinding, and splicing thin sheets of precision ceramic through standardized processes, and then wrapping around the nickel-chromium alloy inner layer to form a stable insulating and protective structure. The aluminum alloy outer shell is made of stamped thin plates through rolling, welding, and other processing steps to form a thin-walled cylindrical structure that completely covers the ceramic insulation layer, providing all-round protection for the internal components. The induction coil is precisely installed at both ends of the heating coil body and is electrically connected to the power connector via wires. The wires are selected to have high-temperature resistance and excellent insulation properties to ensure stable and reliable power transmission, meet the requirements of safe electricity use regulations, and ensure safe and efficient power transmission.

[0014] When the incinerator receives the start command, the current output from the external 36V DC power supply flows smoothly into the induction coil through a stable transmission path formed by the power connector and wires. According to the law of electromagnetic induction, under the influence of the magnetic field generated by the induction coil, the current can be injected precisely and stably into the nickel-chromium alloy inner layer of the circular spiral heating coil. The nickel-chromium alloy, relying on its inherent resistive properties, achieves efficient conversion of electrical energy into heat energy according to Joule's law, causing the inner layer temperature to rise rapidly, thus initiating the heating process.

[0015] The ceramic insulation layer serves a dual function of insulation and heat insulation, ensuring that current is transmitted strictly along the predetermined path to prevent leakage and other abnormalities. It also effectively blocks the disorderly diffusion of heat, guiding heat energy outward along the designed path to the waste. The aluminum alloy casing utilizes its heat dissipation advantages to dissipate the heat accumulated on the casing into the surrounding environment, thereby ensuring that the overall temperature of the equipment remains within a stable and suitable range.

[0016] At this time, the spiral heating coil body transmits heat to the excrement in the toilet liner in a uniform heat radiation mode in a balanced and stable heat flow form. At the same time, combined with the introduction of combustion air through the ventilation duct, the excrement is fully combusted and carbonized in an aerobic environment, and transformed into fine ash in an ideal temperature range, achieving the goal of harmless and volume reduction treatment, and effectively fulfilling the requirements of environmental protection tasks.

[0017] Beneficial Effects: Inner Layer (High-Efficiency Heating Layer): After in-depth research and repeated verification of the material performance spectrum and its adaptability to actual working conditions, nickel-chromium alloy (Kanthal Al) was selected as the core heating material. A comprehensive review and in-depth analysis of cutting-edge literature in materials science, such as "Analysis of the Advantages and Limitations of High-Temperature Alloys in the Electrothermal Field," revealed that its unique alloy ratio constitutes the key element of its superior performance. Nickel forms a good electrical and thermal conductivity framework, while chromium forms a protective system with antioxidant properties. Even in harsh environments with sufficient oxygen content and high temperatures, it can maintain a stable chemical structure, exhibiting excellent properties in terms of oxidation and degradation resistance. In a professional winding workshop with constant temperature, constant humidity, and dust-free standards, using a CNC winding machine, multiple strands of high-temperature resistant and highly conductive alloy wires are driven to perform a tight spiral winding operation according to pre-set winding parameters (including the number of turns, pitch, tension, etc.). The wires are tightly connected to each other, ultimately forming a cylindrical heating core structure. When the power is turned on, thanks to its excellent conductivity, it efficiently converts electrical energy into heat energy according to Joule's law (Q=I²Rt). In the simulation test, compared with traditional iron-chromium-aluminum alloy and pure nickel wire, under the same electrical parameters, it heats up to the working temperature 20%-30% faster and can maintain a stable heating state for more than 5 times longer. It is a key component with high heating efficiency, providing stable and long-lasting heat energy support for incineration operations.

[0018] Intermediate Layer (Insulation and Heat Insulation Layer): Based on rigorous thermal calculation principles and electrical insulation specifications, the thickness of this layer is precisely controlled within the range of 1-2mm. It is made from high-purity alumina-based ceramic material and processed using precision casting technology. In-depth research into professional reports such as "Research on the Thermal Insulation Performance of Ceramic Insulation Materials in Electrothermal Conversion Devices" reveals that its dense crystal structure and low porosity are the core advantages for achieving insulation and heat insulation functions. The insulation resistivity is higher than 10¹²Ω·m, far exceeding the industry safety standard limit, and the thermal conductivity can be as low as 2-3W / (m·K) at high temperatures. After undergoing a series of standardized processes including cutting, grinding, splicing, and high-temperature sintering and curing, it surrounds the inner nickel-chromium alloy layer, constructing a stable insulation and protective structure. Actual thermal imaging data shows that after assembly, the proportion of heat loss to the outer shell is reduced by 40%-50% compared to before, effectively ensuring that heat energy is directionally transferred to the waste to be treated, ensuring stable and high thermal efficiency.

[0019] Outer Layer (Protective Heat Dissipation Layer): Utilizing a thin-walled (2-3mm) aluminum alloy shell, the 6061 aluminum alloy, with its low density (approximately one-third that of steel), perfectly meets the lightweight design requirements of the incinerator toilet. Its shape is achieved through stamping and welding processes, and its mechanical properties are enhanced through aging treatment, resulting in a 30%-40% increase in yield strength and sufficient hardness to withstand impacts during daily use. The surface undergoes anodizing to form a protective film, which has been tested for 500 hours of salt spray corrosion, demonstrating excellent corrosion resistance and effectively mitigating the effects of complex environments. With its excellent thermal conductivity, it performs heat conduction and dissipation, promptly removing excess internal heat and ensuring the internal structure operates within a suitable temperature range, enabling stable operation under complex conditions.

[0020] Shape and Structure: Number of Rings and Spacing Design (Precise Thermal Radiation Layout): A 6-ring spiral structure design was adopted. The spacing between adjacent rings was optimized through hundreds of simulations using Computational Fluid Dynamics (CFD) thermal simulation software, ultimately set at 5mm. The multi-ring structure effectively increases the contact area with the surrounding environment, and together with the precisely set spacing, constructs a highly efficient thermal radiation layout system. CFD simulations and actual testing have verified that this design achieves a heat coverage rate of over 90% for excrement, with a temperature standard deviation controlled within ±5℃. Compared to traditional heating elements, incineration efficiency is improved by 30%-40%, effectively solving the problem of uneven heating.

[0021] Diameter and Length Planning (Adapting to Diverse Scenarios): After comprehensively considering factors such as the aerodynamic principles of the toilet's interior, the physical mechanisms of heat exchange, and the characteristics of waste accumulation, the heating coil diameter was determined to be 5cm. This ensures efficient heat interaction and energy transfer with the surrounding medium. Based on the different cavity volumes and structures of various toilet models, length specifications of 30cm-50cm were customized. Modeling and analysis were conducted based on the heat flow conditions of each type of inner liner, resulting in customized adaptation curves. After adaptation testing, the thermal efficiency was stably maintained in the 80%-90% range, achieving the goal of precise matching and efficient integration with various toilet types.

[0022] Beneficial effects: The multi-layered composite structure works closely together, providing a solid foundation for structural performance.

[0023] The enhanced heating efficiency of the inner layer lays a solid foundation: Traditional heating coils often suffer from low heating efficiency and poor stability due to improper material selection. The nickel-chromium alloy inner layer of this device utilizes a meticulously planned high-density spiral winding process to create a tightly packed cylindrical heating core structure. This structure, combined with the material's excellent properties, achieves highly efficient conversion of electrical energy into heat energy upon energization, based on Joule's law. Compared to traditional materials, under the same electrical parameter settings, the heating rate is increased by 20%-30%, and the duration of stable heating is more than five times longer. This effectively ensures a continuous and robust heat source supply, resolving the problems of insufficient heating efficiency and lack of stability in traditional coils, and providing a solid foundation for subsequent incineration operations.

[0024] Intermediate layer insulation and heat insulation ensure directional heat flow:

[0025] Traditional heating coils often suffer from inadequate insulation, leading to significant heat loss and a high risk of leakage. This device addresses this issue by using a ceramic insulation layer with a precisely designed 1-2mm thickness. This layer undergoes a series of meticulous processes, including cutting, splicing, and high-temperature sintering, to surround the nickel-chromium alloy inner layer, creating a robust and secure insulation system. Its unique crystal structure ensures that current is conducted along a predetermined path, effectively mitigating leakage risks. Actual thermal imaging testing shows that after assembly, unexpected heat loss to the outer shell is reduced by 40%-50%, significantly confining heat to the core heating area. This ensures efficient and directional heat transfer to the waste being treated, successfully overcoming the limitations of traditional insulation and heat dissipation, and solidifying the basic level of thermal efficiency.

[0026] The outer layer provides both protection and heat dissipation:

[0027] In the past, heating coils often lacked comprehensive consideration of protection and heat dissipation performance during the design phase, resulting in easily damaged shells and low heat dissipation efficiency. The outer aluminum alloy shell of this device is made of thin-walled (2-3mm) 6061 aluminum alloy. After stamping and welding, its mechanical properties are enhanced through aging treatment, resulting in a significant increase in yield strength, sufficient to withstand impacts encountered in daily use. The surface undergoes anodizing treatment and has passed a 500-hour salt spray corrosion test, ensuring comprehensive protection. Utilizing its excellent thermal conductivity, it can effectively dissipate heat accumulated in the shell to the external environment, maintaining a suitable temperature range inside the equipment. This effectively reverses the disadvantages of traditional shells, such as poor heat dissipation and insufficient corrosion resistance, extending the overall service life of the device and ensuring stable and continuous operation under complex working conditions.

[0028] Ingenious shape and layout overcome the challenges of uneven heat distribution and compatibility:

[0029] The spiral layout achieves uniform heat radiation efficiency: Traditional heating coils use a linear heating wire layout, resulting in uneven heat distribution during waste incineration. This leads to localized overheating and carbon buildup, while other areas remain undertreated at low temperatures, severely limiting incineration efficiency and actual treatment effectiveness. This device innovatively employs a 6-turn spiral design for its 4-circular spiral heating coil body. The spacing between adjacent turns was repeatedly optimized using Computational Fluid Dynamics (CFD) thermal simulation software, ultimately determining a precise 5mm spacing. This multi-turn spiral structure effectively expands the heat radiation coverage area. Combined with the precisely set spacing parameters, it creates a robust and efficient heat radiation layout system. Verified by both CFD simulation and actual testing, the waste heat coverage exceeds 90%, with the temperature standard deviation controlled within ±5℃. Compared to traditional heating elements, incineration efficiency is improved by 30%-40%, fundamentally changing the existing situation of uneven heat distribution and low incineration efficiency. This ensures uniform heating of the entire waste surface, achieving highly efficient incineration conversion.

[0030] Customized Size for Diverse Applications: Traditional heating coils have a single, fixed specification, making it difficult to match the varying cavity volumes and structural characteristics of different toilet models. This device comprehensively considers the aerodynamic principles inside the toilet, the physical mechanisms of heat exchange, and the characteristics of excrement accumulation, determining a 5cm diameter specification to ensure efficient interaction and collaboration with the internal medium of the toilet. Simultaneously, based on the actual situation of different toilet models, a length range of 30cm-50cm is flexibly customized. By using modeling analysis of the heat flow direction of the inner tank to draw a dedicated adaptation curve, it ensures that the thermal efficiency is stably maintained within the 80%-90% range during the adaptation testing phase. Furthermore, a specially designed metal bracket enables precise positioning and installation, breaking through existing adaptation limitations. Whether it's a small, portable mobile toilet or a large, fixed toilet, it can achieve excellent fit and embedding, effectively broadening the product's practical application scope.

[0031] Optimize the connection between induction and power supply to ensure accurate energy transmission:

[0032] Traditional heating coils often suffer from rudimentary design and poor energy coupling in their power supply configuration and energy coupling, frequently resulting in high energy loss and inadequate transmission stability. This negatively impacts heating efficiency and the overall operation of the equipment. This device, however, precisely positions the induction coils at both ends of the heating coil, establishing a tight electrical connection with the power connector using high-temperature resistant, well-insulated wires, and is powered by a 36V DC power supply. Based on the principle of electromagnetic induction and combined with an equivalent circuit model, the device features a refined design of parameters such as the number of turns and wire diameter, achieving a coupling efficiency exceeding 90% and energy transmission loss controlled within 10%. This ensures that the current can stably and accurately activate the heating function of the nickel-chromium alloy inner layer, effectively solving the problems of low energy transmission efficiency and large fluctuations in traditional designs. This provides a stable and efficient energy supply throughout the incineration process, ensuring smooth and stable equipment operation. Attached Figure Description
