[0039] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0040] In the prior art, incinerating toilets consist of a combustion chamber and a heating wire, which is located within the combustion chamber. During operation, the heating wire reaches a high temperature, which then ignites surrounding excrement. However, this method of igniting excrement with a heating wire is inefficient, produces uneven heating, and leaves a large amount of ash after combustion.

[0041] In order to solve or improve the problems of low heating efficiency and uneven heating of incineration toilets in the related art, an incineration toilet is provided in an embodiment of the present invention.

[0042] The following combination Figures 1 to 5, describing the incineration toilet provided in an embodiment of the present invention.

[0043] Specifically, the incineration toilet includes a main body 1, an incineration chamber 2, a microwave generating device 3 and an exhaust system 4.

[0044] The main body 1 has a cavity therein. Optionally, the main body 1 is made of ceramic or metal. An incineration chamber 2 is disposed within the cavity of the main body 1 and includes a feed port 201 and an exhaust port 202. Optionally, the exhaust port 202 is disposed on a side wall or top wall of the incineration chamber 2. Optionally, the incineration chamber 2 is made of ceramic.

[0045] Optionally, a toilet bowl 101 is provided inside the main body 1, and the toilet bowl 101 has a sewage outlet 102. Optionally, the toilet bowl 101 is configured as a funnel, and the sewage outlet 102 is provided below the toilet bowl 101. The incineration chamber 2 is provided below the toilet bowl 101, and a feed port 201 is provided in the incineration chamber 2 at a position corresponding to the sewage outlet 102. It is understood that the feed port 201 is provided at the top of the incineration chamber 2.

[0046] A microwave generator 3 is connected to the incineration chamber 2 and is configured to transmit electromagnetic waves into the incineration chamber 2 to incinerate materials therein, including, but not limited to, excrement and bags containing excrement. Alternatively, the microwave generator 3 may be configured to output a continuous wave at 2450 MHz.

[0047] The exhaust system 4 is connected to the exhaust port 202 , and is used to discharge the gas in the incineration chamber 2 .

[0048] In this embodiment, during use, after the user goes to the toilet, excrement falls into the incineration chamber 2 through the feed port 201 of the incineration chamber 2 .

[0049] The electromagnetic waves generated by the microwave generator 3 act directly on the excreta in the incineration chamber 2, causing polar molecules (such as water molecules) to vibrate at high speed, generating molecular friction heat and achieving a rapid temperature increase (for example, up to 400°C to 1000°C). The high temperature pyrolyzes and vaporizes the organic matter, while the penetrating microwaves heat the material at the molecular level, allowing for more uniform treatment of the excreta and avoiding the localized carbonization problem associated with traditional incineration.

[0050] During the excreta treatment process, the gasification products in the incineration chamber 2 can be discharged through the exhaust system 4 to maintain the air pressure balance inside the incineration chamber 2. The exhaust system 4 also guides the gas in the incineration chamber 2 to a designated location to facilitate subsequent treatment of the waste gas generated by the incineration.

[0051] In summary, this arrangement allows microwave treatment to rapidly pyrolyze excreta, essentially breaking it down into harmless substances and reducing environmental pollution. Furthermore, compared to traditional incineration methods, microwaves heat the object more deeply and evenly, thereby improving treatment efficiency and reducing the time excreta remains within the incineration chamber 2. Furthermore, microwave energy can be concentrated on the excreta, eliminating idle losses and achieving higher energy efficiency.

[0052] In some embodiments provided herein, a waveguide cavity 203 is provided on the outer wall of the incineration chamber 2, and the microwave generator 3 is connected to the waveguide cavity 203, that is, the microwave generator 3 transmits electromagnetic waves into the incineration chamber 2 through the waveguide cavity 203. Optionally, the waveguide cavity 203 is a closed metal cavity, which is provided on the outer wall of the incineration chamber 2, and the probe of the microwave generator 3 extends into the interior of the waveguide cavity 203.

[0053] In this embodiment, the waveguide cavity 203 can guide the microwaves to be transmitted along a preset direction, reducing the energy loss and scattering of the microwaves during the transmission process, allowing the microwaves to enter the incineration chamber 2 more concentratedly and efficiently, thereby improving the utilization rate of microwave energy, and thus more effectively heating and incinerating the excrement in the incineration chamber 2.

[0054] The waveguide cavity 203 can appropriately modulate and distribute the microwaves, making the microwaves more evenly distributed in the incineration chamber 2, avoiding excessively high or low microwave energy in certain areas of the incineration chamber 2, ensuring that the excrement can be evenly heated and incinerated, and improving the treatment effect and quality.

[0055] Connecting the microwave generator 3 to the incineration chamber 2 through the waveguide cavity 203 can keep the microwave generator 3 away from the high temperature environment of the incineration chamber 2, reduce the impact of high temperature on the microwave generator 3, reduce the risk of device damage, and extend its service life.

[0056] The waveguide cavity 203 can effectively limit the propagation range of microwaves, reduce the possibility of microwave leakage, reduce the radiation hazards to the surrounding environment and human body, and improve the safety of using the incineration toilet.

[0057] In some embodiments provided by the present invention, the microwave generating device 3 includes a magnetron, which is connected to the incineration chamber 2. For example, the magnetron is connected to the incineration chamber 2 through a waveguide cavity 203.

[0058] In this embodiment, the magnetron efficiently converts electrical energy into microwave energy. It utilizes the movement of electrons in magnetic and electric fields to generate high-power microwaves, resulting in high energy conversion efficiency. This allows for rapid and effective heating and incineration of objects within the incineration chamber 2, improving processing efficiency.

[0059] The magnetron can generate microwaves with a stable frequency. In the application of incineration toilets, the stable microwave frequency helps to ensure the consistency and reliability of microwave heating, so that the excreta in the incineration chamber 2 can be evenly heated to achieve a good incineration effect.

[0060] The magnetron has a relatively simple structure, consisting primarily of a cathode, an anode, and a resonant cavity. This simple structure makes the magnetron's manufacturing process relatively mature and low-cost. It also facilitates installation and maintenance, reducing the complexity and maintenance costs of the entire incineration toilet system.

[0061] In some embodiments provided by the present invention, the exhaust system 4 includes at least one of a catalytic device 401 , a dust collection device 402 , and a cooling device 403 .

[0062] Catalytic device 401 is used to catalytically decompose substances emitted from incinerator 2. These substances include, but are not limited to, ammonia, carbon monoxide, and skatole. Catalytic device 401 can catalytically decompose harmful substances in the exhaust gas from incinerator 2, such as ammonia, carbon monoxide, and skatole, converting them into harmless or less harmful substances. For example, it can catalytically oxidize carbon monoxide to carbon dioxide, thereby significantly reducing environmental pollution from the exhaust gas and protecting the atmospheric environment and human health.

[0063] Dust collection device 402 is used to collect particulate matter from the exhaust of incineration chamber 2. This effectively collects particulate matter from the exhaust of incineration chamber 2, preventing it from being released into the air. This reduces dust pollution and helps maintain a clean environment. It also prevents particulate matter from entering other equipment or ventilation systems, preventing damage such as wear and clogging, thereby extending the service life of the equipment.

[0064] Cooling device 403 is used to cool the material discharged from incineration chamber 2. The material discharged from incineration chamber 2 is relatively hot. If not cooled, the exhaust system 4's pipes, fans, and other components could be damaged due to prolonged high temperatures. Cooling device 403 reduces the gas temperature to an appropriate range, ensuring the proper operation of exhaust system 4 and extending the equipment's service life.

[0065] In some embodiments provided by the present invention, reference Figure 3 As shown, the catalytic device 401 is connected to the exhaust port 202 of the incineration chamber 2, the dust collecting device 402 is arranged downstream of the catalytic device 401 and connected to the catalytic device 401, and the cooling device 403 is arranged downstream of the dust collecting device 402 and connected to the dust collecting device 402.

[0066] In this embodiment, the catalytic device 401 is connected to the exhaust port 202 of the incineration chamber 2 , so that the waste heat of the exhaust gas can be used to maintain the catalytic reaction temperature, thereby reducing the additional energy consumption required by the catalytic device 401 .

[0067] The dust collecting device 402 is arranged downstream of the catalytic device 401 to collect particulate matter in the gas, thereby preventing the particulate matter from causing wear or blockage to the downstream cooling device 403 or the fan.

[0068] The cooling device 403 is connected to the downstream of the dust collecting device 402 and can cool the gas discharged from the dust collecting device 402 to prevent the high-temperature gas from damaging downstream equipment or users.

[0069] Optionally, the dust collecting device 402 is configured as an electrostatic dust removal device, a filtering device, or a centrifugal dust removal device.

[0070] In some embodiments provided by the present invention, the cooling device 403 includes an air-to-air heat exchanger. Optionally, the air-to-air heat exchanger is a plate heat exchanger or a fin-tube heat exchanger.

[0071] Furthermore, the incineration chamber 2 is further provided with an air inlet 204 , the exhaust port 202 of the incineration chamber 2 is connected to the heat release channel of the gas-to-gas heat exchanger, and the air inlet 204 is connected to the heat absorption channel of the gas-to-gas heat exchanger.

[0072] In this way, the material discharged from the incineration chamber 2 can be heat exchanged with the combustion air before entering the incineration chamber 2 in the cooling device 403, thereby recovering the waste heat of the exhaust gas in the incineration chamber 2, which is used to preheat the combustion air entering the incineration chamber 2, thereby improving the incineration efficiency and energy utilization, and avoiding the cold air from affecting the temperature in the incineration chamber 2, thereby ensuring the incineration effect in the incineration chamber 2.

[0073] In some embodiments not shown, cooling device 403 includes a gas-liquid heat exchanger, and the liquid can be water. Water has a high specific heat capacity and can quickly cool the exhaust gas to a safe temperature. In addition, cooling device 403 can be used to supply hot water, improving energy efficiency.

[0074] Of course, cooling device 403 can include both an air-to-air heat exchanger and an air-to-liquid heat exchanger, with the heat release channel of the air-to-liquid heat exchanger connected downstream of the heat release channel of the air-to-air heat exchanger, so that the gas exhausted from incineration chamber 2 can pass through the air-to-air heat exchanger and the air-to-liquid heat exchanger in sequence. In this way, the gas exhausted from incineration chamber 2 can be used to heat combustion air and hot water, thereby improving energy efficiency.

[0075] In some embodiments provided by the present invention, the catalytic device 401 includes a carrier 4011 , a catalyst, and a heating device 4012 .

[0076] The carrier 4011 can be a honeycomb ceramic carrier or an alumina carrier. Optionally, the carrier 4011 is disposed in a housing 4013 of the catalytic device 401 , which is connected to the exhaust port 202 of the incineration chamber 2 and further connected to the dust collection device 402 .

[0077] The catalyst is arranged on the carrier 4011. The catalyst can be a precious metal catalyst (such as platinum / palladium) or a metal oxide catalyst (such as MnO2-CeO2). At 200°C to 400°C, harmful gases can be oxidized into harmless substances.

[0078] The heating device 4012 is used to heat the gas to be catalyzed so that the temperature of the catalytic reaction meets the actual requirements. For example, the heating device 4012 can be an electric heater.

[0079] In this embodiment, the carrier 4011 is arranged in the shell 4013 of the catalytic device 401, and the shell 4013 is connected to the exhaust port 202 of the incineration chamber 2, so that the harmful gas discharged from the incineration chamber 2 can smoothly enter the catalytic device 401 for treatment. At the same time, the shell 4013 is also connected to the dust collection device 402, which facilitates the gas after catalytic treatment to enter the dust collection device 402 for the next step of treatment. This structural design ensures the continuity and efficiency of the gas treatment process.

[0080] The temperature of the carrier 4011 can be precisely controlled by the heating device 4012 to meet the actual needs of the catalytic reaction, ensuring that the catalyst is always in the best active state, thereby improving the conversion rate of harmful gases.

[0081] In some embodiments provided herein, the exhaust system 4 further includes an exhaust fan 404, the air inlet end of the exhaust fan 404 being connected to the exhaust port 202, and the exhaust fan 404 being used to drive the gas within the incineration chamber 2 out. Optionally, the exhaust fan 404 is disposed downstream of the cooling device 403, and the air inlet end of the exhaust fan 404 is connected to the cooling device 403. Optionally, the exhaust fan 404 is configured as a centrifugal fan.

[0082] In this embodiment, an exhaust fan 404 is provided to be connected to the exhaust port 202 of the incineration chamber 2 , so that the gas in the incineration chamber 2 can be quickly discharged under the action of the exhaust fan 404 .

[0083] In addition, the exhaust fan 404 is connected to the downstream of the cooling device 403, so that the gas is cooled by the cooling device 403 and then enters the exhaust fan 404. The temperature of the gas after cooling by the cooling device 403 is reduced, which can prevent the exhaust fan 404 from directly contacting the high-temperature gas, prevent the components of the exhaust fan 404 from being damaged due to long-term heat, and extend the service life of the exhaust fan 404.

[0084] In addition, the volume of the cooled gas shrinks and the density increases, making it easier to flow under the action of the exhaust fan 404, which helps to improve the overall exhaust efficiency of the exhaust system 4 and enables the gas in the incineration chamber 2 to be discharged more quickly.

[0085] In some embodiments provided by the present invention, the incineration chamber 2 is further provided with an air inlet 204. By providing the air inlet 204, oxygen can be added to the incineration chamber 2 through the air inlet 204 so that the excrement can be fully pyrolyzed.

[0086] In this embodiment, the introduction of oxygen can drive the reaction toward complete combustion (producing CO2 and H2O). Specifically, the introduction of oxygen provides more oxidant for the incineration process, allowing the organic matter in the excreta to fully come into contact with oxygen and undergo an oxidation reaction, thereby accelerating the combustion rate, improving combustion efficiency, and achieving a more complete incineration process. This can more thoroughly convert organic matter into harmless substances such as carbon dioxide and water, reduce the generation of incomplete combustion products, and minimize environmental pollution.

[0087] Sufficient oxygen can make the combustion reaction more intense, release more heat, and thus increase the temperature in the incineration chamber 2. That is, the heat released by the oxidation reaction can supplement the energy demand of microwave heating, reduce the microwave power required to maintain high temperature, and make the oxidation reaction and microwave incineration produce a synergistic heating effect, thereby reducing the power demand of the incineration toilet.

[0088] Furthermore, higher temperatures help accelerate various chemical reactions, allowing the non-flammable components in the excreta to burn better, further improving the incineration effect. It also helps kill possible pathogens and parasite eggs, etc., to achieve better harmless treatment purposes.

[0089] Optionally, during the microwave treatment of excreta, an oxygen-deficient pyrolysis followed by oxygen-enriched incineration is employed. Specifically, the air inlet 204 is first closed, and the excreta is treated with microwaves for a first preset time. Then, the air inlet 204 is opened, air is introduced into the incineration chamber 2 through the air inlet 204, and the excreta is treated with microwaves for a second preset time. The first and second preset time periods can be adjusted as needed.

[0090] In this embodiment, under oxygen-deficient conditions, the organic matter in the excreta undergoes a pyrolysis reaction, breaking down complex organic macromolecules into relatively simple, small, combustible gases such as carbon monoxide, hydrogen, and methane, as well as coke and tar. This process can be carried out at relatively low temperatures, avoiding the localized overheating and energy waste that can occur with direct combustion, while also reducing the generation of harmful gases such as nitrogen oxides.

[0091] In addition, during the anoxic pyrolysis stage, the combustion temperature is relatively low due to the low oxygen content, which inhibits the reaction of nitrogen in the air with oxygen to form nitrogen oxides. This is because the formation of nitrogen oxides is closely related to the combustion temperature and oxygen concentration, and an oxygen-deficient environment is not conducive to the formation of nitrogen oxides.

[0092] The products after anaerobic pyrolysis are incinerated in an oxygen-rich environment. Since the pyrolysis products are small molecules that are relatively easy to burn, they can burn quickly and fully under the action of sufficient oxygen, releasing a large amount of heat, thereby improving the efficiency of the entire combustion process and making more effective use of energy.

[0093] Furthermore, the initial anaerobic pyrolysis process prevents direct combustion of organic matter under high-temperature, oxygen-rich conditions, reducing the formation of dioxin precursors. In the subsequent oxygen-enriched incineration phase, the pyrolysis products burn fully, resulting in a shorter residence time and a reduced production of dioxins, thereby reducing emissions of dioxins and other harmful pollutants.

[0094] Furthermore, in order to fully burn the pyrolysis products in the incineration chamber 2 under oxygen-rich conditions, air inlets 204 can be respectively provided at the bottom and side walls of the incineration chamber 2. The air inlet 204 at the bottom can promote the full combustion of solid or liquid substances at the bottom of the incineration chamber 2, and the air inlet 204 at the side walls can promote the full combustion of gases in the incineration chamber 2.

[0095] Optionally, the air inlet 204 may be provided with a control valve, such as a gate valve or a ball valve, for opening and closing the air inlet 204 or adjusting the amount of gas entering the incineration chamber 2 .

[0096] Optionally, a temperature detection device can be installed within the incineration chamber 2 to monitor the temperature within the incineration chamber 2 and adjust the power of the microwave generator 3 based on the temperature. For example, if the pyrolysis temperature or incineration temperature is insufficient, the power of the microwave generator 3 can be increased to avoid incomplete pyrolysis. Alternatively, if the temperature within the incineration chamber 2 is too high, the power of the microwave generator 3 can be reduced to avoid energy waste.

[0097] Optionally, the temperature detection device can be configured as a thermocouple, a thermal resistor or an infrared temperature measuring device. The control process can be executed by the control device 9, that is, the control device 9 adjusts the power of the microwave generating device 3 based on the temperature value.

[0098] Optionally, as exhaust fan 404 exhausts gas from incineration chamber 2, the pressure within incineration chamber 2 drops, allowing air to be drawn in through air inlet 204. This allows air to be automatically drawn in through air inlet 204, eliminating the need for an additional power unit to drive the air intake. This reduces the complexity and cost of the equipment. Furthermore, this approach eliminates the need for additional moving parts, reduces the probability of failure, and improves system reliability and stability.

[0099] Of course, in some embodiments, the incineration toilet may further include an air supply device 5, which is connected to the incineration chamber 2 and is used to supply air to the incineration chamber 2. That is, the air outlet of the air supply device 5 is connected to the air inlet 204 of the incineration chamber 2 to supply air into the incineration chamber 2. The air supply device 5 may be an air blower, including but not limited to an axial flow fan or a centrifugal fan.

[0100] In this embodiment, the air supply device 5 can accurately adjust the air supply volume according to the operating requirements of the incineration toilet to ensure combustion requirements. For example, forced air supply can ensure sufficient oxygen and reduce the generation of unburned carbon particles and CO.

[0101] Optionally, the air inlet 204 is further connected to a cooling device 403 of the exhaust system 4 via an air inlet pipe. The cooling device 403 is configured as an air-to-air heat exchanger. In this way, the material discharged from the incineration chamber 2 can exchange heat with the combustion air before entering the incineration chamber 2 within the cooling device 403, thereby recovering the waste heat of the exhaust gas in the incineration chamber 2 and using it to preheat the combustion air entering the incineration chamber 2, thereby improving the incineration efficiency and energy utilization.

[0102] It is understandable that the incineration toilet can be equipped with either the air supply device 5 or the exhaust fan 404, or both the air supply device 5 and the exhaust fan 404 can be arranged at the same time.

[0103] In some embodiments provided herein, a packing bag can be placed within the main body 1, with a drawstring provided at the bag opening. It is understood that the packing bag is intended for placement within the toilet bowl 101, and the drawstring structure of the packing bag can be similar to that of a drawstring garbage bag. Specifically, a hollow channel is provided around the packing bag, the drawstring is threaded through the channel, and a portion of the drawstring is positioned outside the channel for user extraction. The packing bag's material is soft and naturally gathers as the drawstring contracts, forming a seal.

[0104] Furthermore, the incinerating toilet also includes a first seat body 11 , a second seat body 12 , a shearing mechanism 13 and a reciprocating drive mechanism 14 .

[0105] At least one of the first base 11 and the second base 12 is slidably connected to the main body 1, and the first base 11 and the second base 12 can move closer to or farther from each other. Figure 4 and Figure 5 What is shown is an example in which the first base body 11 and the second base body 12 are both slidably connected to the main body 1 . Of course, in some embodiments not shown, the first base body 11 or the second base body 12 is slidably connected to the main body 1 .

[0106] The reciprocating drive mechanism 14 is used to drive the first base 11 and the second base 12 toward or away from each other. For example, the reciprocating drive mechanism 14 includes a lead screw 1401 and a motor 1402. The motor 1402 is mounted on the main body 1, and the output of the motor 1402 is connected to the lead screw 1401. In embodiments in which both the first base 11 and the second base 12 are slidably connected to the main body 1, the first base 11 and the second base 12 are both threadedly connected to the lead screw 1401, and the threads of the first base 11 and the second base 12 have opposite rotation directions. Thus, by driving the lead screw 1401 by the motor 1402, the first base 11 and the second base 12 can be moved toward or away from each other.

[0107] Of course, for the embodiment in which one of the first base 11 and the second base 12 is slidably connected to the main body 1, the lead screw 1401 is only threadedly connected to the slidable first base 11 or the second base 12. In addition, for the embodiment in which one of the first base 11 and the second base 12 is slidably connected to the main body 1, the reciprocating drive mechanism 14 can also be configured as a pneumatic cylinder or an oil cylinder.

[0108] The shearing mechanism 13 includes a first cutter 1301 provided on the first base 11 and a second cutter 1302 provided on the second base 12 . The first cutter 1301 and the second cutter 1302 are used to cut the draw cord together.

[0109] In this embodiment, before using the toilet, the user can place a packing bag inside the main body 1. After use, the user can seal the bag by pulling the drawstring. This prevents excrement from contaminating the interior of the main body 1, eliminating the need to clean the main body 1 after use. This makes the incineration toilet more suitable for environments where water is not readily available, such as in RVs or scientific research stations.

[0110] In addition, by sealing the packing bag with a drawstring, it is possible to prevent odor from leaking out, and it is also possible to prevent excrement from leaking out of the packing bag when entering the incineration chamber 2 from the toilet bowl 101.

[0111] Furthermore, after the drawstring shrinks and the packaging bag is shrunk, the longer part of the drawstring is exposed outside the packaging bag. After the packaging bag enters the incineration chamber 2, the drawstring may remain outside the incineration chamber 2, causing the incineration chamber 2 to be poorly sealed.

[0112] In this embodiment, the first base body 11 and the second base body 12 are driven to approach each other by the reciprocating drive mechanism 14, and the first cutter 1301 and the second cutter 1302 on the first base body 11 and the second base body 12 can approach each other to produce a shearing effect. After pulling the draw rope of the packing bag, the draw rope can be placed between the first cutter 1301 and the second cutter 1302, so that the draw rope can be cut by the first cutter 1301 and the second cutter 1302 to avoid the draw rope being exposed too long.

[0113] It is understandable that the action of pulling the pull cord can be completed by the user, or a corresponding pulling mechanism can be provided, and there is no limitation on this.

[0114] In some embodiments provided by the present invention, the incinerating toilet further includes a hot melt mechanism 15 , which is disposed on a side of the shearing mechanism 13 close to the center of the toilet bowl 101 . The hot melt mechanism 15 includes a hot melt head 1501 and a cutting board 1502 .

[0115] One of the hot melt head 1501 and the chopping board 1502 is located on the first base 11, while the other is located on the second base 12. The hot melt head 1501 and the chopping board 1502 are positioned opposite each other and are used to clamp and heat-seal the packaging bag. Specifically, the hot melt head 1501 heats the packaging bag, which can be electrically heated, and the chopping board 1502 cooperates with the hot melt head 1501 to squeeze the packaging bag.

[0116] In this embodiment, the hot melt mechanism 15 is arranged on the side of the shearing mechanism 13 close to the center of the main body 1. After the user finishes using the toilet, he pulls the drawstring of the packing bag so that the drawstring passes between the first knife 1301 and the second knife 1302. Then, under the pulling action of the drawstring, the bag opening of the packing bag is located between the hot melt head 1501 and the chopping board 1502.

[0117] Then, the first base body 11 and the second base body 12 are driven closer to each other by the reciprocating drive device, and the first cutter 1301 and the second cutter 1302 are moved closer to each other, which can cut the drawstring rope. At the same time, the hot melt head 1501 and the chopping board 1502 are moved closer to each other, which can squeeze and hot melt the packaging bag to seal the packaging bag.

[0118] In this way, the hot melt mechanism 15 and the shearing mechanism 13 are combined together, and the hot melt sealing of the packaging bag is performed while the drawstring is cut, thereby integrating the two functions, reducing the steps of setting up the sealing operation separately, improving the overall work efficiency, and saving the user's time.

[0119] In addition, hot melt sealing can make the packaging bag seal tighter, thereby better suppressing the leakage of odor or excrement.

[0120] In some embodiments provided by the present invention, the first base body 11 is provided with a support member 16 extending toward the second base body 12 , and the second base body 12 is provided with an avoidance groove for the support member 16 to pass through, and the support member 16 is used to support the packaging bag.

[0121] In this embodiment, after using the toilet, the drawstring of the packing bag is pulled so that the drawstring passes over the support member 16. The support member 16 can support and limit the drawstring and the packing bag to prevent them from falling downward, so that the drawstring can be better maintained between the first tool 1301 and the second tool 1302, and the packing bag can be better maintained between the hot melt head 1501 and the anvil 1502, thereby ensuring that the cutting operation and the hot melt operation can be completed stably.

[0122] By providing an avoidance groove on the second base body 12 , the support member 16 can slide relative to the second base body 12 , so that the support member 16 can always maintain a supporting effect when the first base body 11 and the second base body 12 approach or move away from each other.

[0123] Optionally, the support member 16 may be configured as a support plate.

[0124] In some embodiments provided by the present invention, the incineration toilet further includes a shielding door 6, which is movably provided and used to open and close the feed port 201. Optionally, the shielding door 6 can be provided as a metal door.

[0125] In this embodiment, the shielding door 6 acts as a physical barrier, effectively preventing microwaves from leaking from the feed port 201. When closed, the shielding door 6 forms a relatively enclosed space between the incineration chamber 2 and the outside world. The shielding door 6 reflects and absorbs microwaves, significantly reducing the possibility of microwaves penetrating and leaking into the external environment, thus protecting users from the potential hazards of microwave radiation.

[0126] In addition, the shielding door 6 is used to seal the feed port 201, which can maintain a good shielding effect of the incineration chamber 2, ensuring that the microwave energy is concentrated in the room for the treatment of excrement, thereby improving energy utilization efficiency.

[0127] In addition, closing the incineration chamber 2 by the shielding door 6 can also reduce the diffusion and leakage of harmful substances during the treatment process, and avoid the loss of heat radiation in the incineration chamber 2, thereby ensuring the high temperature effect in the incineration chamber 2.

[0128] Optionally, the shielding door 6 is slidably connected to the main body 1 or the incineration chamber 2, so as to open or close the feed port 201 by translation. For example, a guide rail for guiding the shielding door 6 is provided on the main body 1 or the incineration chamber 2.

[0129] Of course, the shielding door 6 is not limited to being slidably connected to the main body 1 or the incineration chamber 2. For example, in other embodiments, the shielding door 6 is rotatably connected to the main body 1 or the incineration chamber 2, and the rotation axis of the shielding door 6 is arranged in the vertical direction, so that the shielding door 6 can open or close the feed port 201 by horizontal rotation.

[0130] In some embodiments provided by the present invention, the outer wall of the incineration chamber 2 is provided with a heat insulation layer 205 .

[0131] In this embodiment, the thermal insulation layer 205 effectively blocks heat from diffusing from the interior of the incineration chamber 2 to the external environment, thereby retaining the heat within the incineration chamber 2 and reducing heat loss. This helps maintain a high temperature environment within the incineration chamber 2, ensuring a stable incineration process, improving combustion efficiency, and reducing energy consumption.

[0132] The thermal insulation layer 205 can prevent the outer wall of the incineration chamber 2 from being overheated, preventing the surrounding equipment, pipelines, etc. from being damaged due to long-term heat exposure, thereby extending the service life of the related equipment. In addition, it can also prevent the surrounding objects from burning due to the high temperature of the outer wall, reduce the risk of fire, and ensure the safety of the surrounding environment.

[0133] The heat-insulating layer 205 can reduce the heat radiation outward from the incineration chamber 2, avoid heat damage to surrounding personnel and objects, reduce the heat exposed to operators, and improve the user comfort of the incineration toilet.

[0134] Optionally, the thermal insulation layer 205 is configured as a ceramic fiber thermal insulation material, a rock wool thermal insulation material, an aerogel thermal insulation material, or a foam glass thermal insulation material.

[0135] In some embodiments provided by the present invention, the incineration chamber 2 and the microwave generating device 3 are both arranged inside the main body 1 .

[0136] In this embodiment, the main body 1 can provide physical protection for the internal incineration chamber 2 and the microwave generator 3, preventing people from directly contacting the high-temperature incineration chamber 2 and the microwave generator 3 that may emit radiation, reducing the risk of burns and microwave radiation, and ensuring the safety of users.

[0137] This design can concentrate related functional components in a relatively compact space, making the overall structure more compact and reasonable, effectively saving installation space, and facilitating installation and layout in different locations. It is especially suitable for environments with limited space, such as small bathrooms, mobile toilets, etc.

[0138] The relatively stable environment inside the main body 1 can provide certain protection for the incineration chamber 2 and the microwave generating device 3, reduce the impact of external factors (such as dust, water vapor, collision, etc.) on them, help to extend the service life of the equipment, and improve the reliability and stability of the equipment.

[0139] In some embodiments provided by the present invention, the incinerating toilet further includes a seat 7 and a toilet cover 8.

[0140] The seat ring 7 is arranged on the top of the main body 1 and is arranged around the edge of the toilet bowl 101. The toilet cover 8 is rotatably connected to the seat ring 7 and is used to open and close the toilet bowl 101.

[0141] In this embodiment, the integrated design of the incinerating toilet seat 7 and lid 8 maintains the basic functions of a traditional toilet. Furthermore, closing the lid 8 during the incineration process, combined with the negative pressure generated by the exhaust system 4, further prevents harmful gases from being discharged from the toilet bowl 101, improving the user experience.

[0142] In some embodiments provided by the present invention, the incineration toilet further includes a control device 9, which is electrically connected to the microwave generating device 3. The control device 9 may be a microprocessor.

[0143] For example, the control device 9 can precisely control parameters such as the start and stop of the microwave generator 3, as well as the microwave output power and frequency. For example, depending on the type and amount of waste in the toilet, the control device 9 can set the appropriate microwave power and duration to achieve efficient and energy-saving incineration, ensuring that the waste is thoroughly treated without wasting energy or over-processing.

[0144] Optionally, the incineration toilet further includes a power supply 10 connected to the microwave generator. For example, power supply 10 is a DC power supply with adjustable voltage.

[0146] Of course, the features in the above-mentioned embodiments can be combined with each other. For example, in some embodiments provided by the present invention, the incineration toilet includes a main body 1, an incineration chamber 2, a microwave generating device 3, an exhaust system 4, a shielding door 6, a power supply 10 and a control device 9.

[0147] The main body 1 is provided with a toilet bowl 101, and the toilet bowl 101 has a sewage outlet 102. Optionally, the toilet bowl 101 is provided in a funnel shape, and the sewage outlet 102 is provided below the toilet bowl 101. Optionally, the main body 1 is provided with ceramic or metal.

[0152] The catalytic device 401 includes a carrier 4011 , a catalyst, and a heating device 4012 .

[0153] The carrier 4011 may be a honeycomb ceramic carrier 4011. Optionally, the carrier 4011 is disposed in a housing 4013 of the catalytic device 401. The housing 4013 is connected to the exhaust port 202 of the incineration chamber 2. Furthermore, the housing 4013 is also connected to the dust collection device 402.

[0154] The catalyst is arranged on the carrier 4011. The catalyst can be a precious metal catalyst (such as platinum / palladium) or an oxide catalyst (such as MnO2-CeO2). At 200°C to 400°C, harmful gases can be oxidized into harmless substances.

[0155] The heating device 4012 is used to heat the carrier 4011 so that the temperature of the catalytic reaction meets actual requirements. For example, the heating device 4012 can be an electric heater.
