DETAILED DESCRIPTION

[0026] The technical scheme and technical effects of the present invention are further elaborated in detail below in conjunction with the accompanying drawings of the present invention.

[0027] Please see Figures 1 to 3 In a specific embodiment, a waterless environmentally friendly toilet 10 achieves degradation of human excrement through microbial degradation technology, meeting the use requirements of toilets in areas with water shortage or no tap water access. It includes a toilet body 100, a microbial degradation chamber 200 and a mixing and stirring device 300. The microbial degradation chamber 200 is installed in the toilet body 100 and filled with padding for meeting the basic living environment of microorganisms. The stirring end of the mixing and stirring device 300 is arranged in the cavity of the microbial degradation chamber 200 and buried in the padding.

[0028] The cavity wall of the microbial degradation chamber 200 includes a semicircular bottom 210, a transition portion 220 and a connecting portion 230, wherein one end of the transition portion 220 is smoothly connected to the semicircular bottom 210, and the other end is connected to the connecting portion 230. The outer wall of the microbial degradation chamber 200 and the inner wall of the toilet body 100 surround to form a heating cavity 400, and the heating cavity 400 is filled with a heating material capable of generating heat.

[0029] Human excrement falls into the microbial degradation chamber 200 from the upper part of the toilet body 100, and is mixed with the padding in the microbial degradation chamber 200 under the action of the mixing and stirring device 300. The microorganisms inoculated in the padding preferentially degrade the human excrement into carbon dioxide, water, etc., and volatilize and discharge. In this process, the heating temperature of the heating material in the heating chamber 400 can be adjusted to make the microorganisms in the microbial degradation chamber 200 in a highly active state, shorten the time for human excrement to be degraded, and reduce odor emissions. At the same time, during the rotation of the mixing and stirring device 300, the padding in the microbial degradation chamber 200 is evenly dispersed in the semicircular bottom 210, and there is no blind spot or dead corner of stirring, thereby avoiding the accumulation of human excrement in the blind spot or dead corner of stirring, and generating a strong odor.

[0030] It is worth noting that in the waterless environmentally friendly toilet 10, the padding in the microbial degradation chamber 200 is a crushed material of herbaceous or woody plants, such as sawdust, wood chips, bran, rice husk powder, etc. The inoculated microorganisms are beneficial bacteria that can quickly decompose human excrement. For example, the inoculated microorganisms are composed of at least one of Enterococcus faecalis, Bacillus subtilis, Pseudomonas and spore-eating cellulotrophic bacteria. For example, the inoculated microorganisms, in terms of the number of live bacteria, include 45% to 60% Enterococcus faecalis, 10% to 20% Bacillus subtilis, 10% to 20% Pseudomonas and 10% to 20% spore-eating cellulotrophic bacteria. For example, the inoculated microorganisms, in terms of the number of live bacteria, are composed of 50% Enterococcus faecalis, 20% Bacillus subtilis, 10% Pseudomonas and 20% spore-eating cellulotrophic bacteria. The process of microbial decomposition or degradation of human excrement not only completely decomposes the organic components contained in human excrement into harmless gases or water, but also greatly reduces or inhibits the pathogens in human excrement, which is safe and hygienic.

[0031] The heating material can be selected from materials with faster thermal conductivity, preferably graphene, which has a small specific heat capacity, fast thermal conductivity, and uniform heat transfer, can effectively improve the efficiency of heat conduction, and at the same time has a good thermal insulation effect.

[0032] Furthermore, the waterless environmentally friendly toilet 10 also includes a gasket adding component, which includes a feeding funnel and a crushing and stirring device arranged on the feeding funnel. The outlet of the feeding funnel is connected to the microbial degradation chamber 200. On the one hand, when the waterless environmentally friendly toilet 10 is idle for a long time or has been used for a certain period of time, it is necessary to add gaskets to the microbial degradation chamber 200 to maintain the normal activities of microorganisms. At this time, the gaskets are added to the microbial degradation chamber 200 through the feeding funnel. On the other hand, the used toilet paper with human excrement or the used toilet paper can be directly crushed by the crushing and stirring, and then enter the microbial degradation chamber 200 through the feeding funnel for decomposition and degradation, which can reduce the usage of padding to a certain extent. More importantly, the used toilet paper with human excrement or the used toilet paper is crushed and then enters the microbial degradation chamber 200 to be degraded or decomposed by microorganisms, thereby preventing the toilet paper or the toilet paper from being exposed to the air for a long time, generating odor, causing the spread of pathogens, and making the waterless environmentally friendly toilet 10 safer and more hygienic.

[0033] Furthermore, the waterless environmentally friendly toilet 10 also includes a nutrient matrix storage box, which is arranged in the microbial degradation chamber 200 and has a self-opening valve at the bottom. The control mechanism of the self-opening valve is arranged at a position outside the toilet body 100 that is easy to operate, so that when the waterless environmentally friendly toilet 10 is idle for a long time, the nutrient matrix storage box can be opened to replenish the nutrient matrix in the microbial degradation chamber 200 to maintain the activity of microorganisms.

[0034] In one embodiment, the waterless environmentally friendly toilet 10 further includes an equipment installation cavity 500, which is disposed at the rear end of the toilet body 100 to install a driving motor 330 of the mixing and stirring device 300 and a temperature control circuit for adjusting the temperature.

[0035] Please also see Figure 4 and Figure 5 Furthermore, in order to allow human excrement to be fully mixed with the bedding during the stirring process and improve the degradation efficiency of microorganisms, the mixing and stirring device 300 includes a stirring shaft 310 and a plurality of stirring blades 320, and the stirring blades 320 are arranged side by side on the stirring shaft 310. The stirring blades 320 include a long-axis blade 321, a sleeve ring 322, and a short-axis blade 323, and the sleeve ring 322 is sleeved on the stirring shaft 310. The long-axis blade 321 and the short-axis blade 323 are arranged on both sides of the sleeve ring 322, and the length of the long-axis blade 321 is greater than the length of the short-axis blade 323. Specifically, the driving motor 330 is arranged at one end of the stirring shaft 310, and the driving motor 330 is installed in the equipment installation cavity 600, and is connected to one end of the stirring shaft 310 through a bearing to drive the stirring shaft 310 to rotate along the axis. The stirring blades 320 are evenly arranged on the stirring shaft 310 and are sleeved with the stirring shaft 310 through the sleeve ring 322. The long-axis blades 321 and the short-axis blades 323 are respectively arranged on both sides of the sleeve ring 322, that is, one side of the blades on both sides of the sleeve ring 322 is longer, which is the long-axis blade 321, and the other side is shorter, which is the short-axis blade 323. In the process of the stirring shaft 310 driving the stirring blades 320 to rotate, the long-axis blades 321 disturb the upper layer and the bottom layer of the padding material so that the human excrement is fully mixed with the padding, and the short-axis blades 323 disturb the middle part of the padding so that the periphery of the padding and the middle part of the padding are fully mixed, so that the padding is layered, disturbed and mixed, and the mixing is more sufficient, preventing the human excrement from always being in the upper layer, bottom layer or periphery of the padding during the stirring process and being unable to be fully mixed, thereby allowing the microorganisms in the padding to fully contact with the human excrement and accelerate the degradation rate.

[0036] In order to further improve the mixing uniformity and improve the microbial degradation efficiency, the long-axis blade 321 and the short-axis blade 323 are arranged on the blade 324 at one end away from the sleeve ring 322. The blade 324 is parallel to the stirring shaft 310 and extends to both sides to increase the contact area between the stirring blade 320 and the pad, increase the amplitude of the disturbance of the stirring blade 320 in the pad, and thereby make the human excrement and the pad mix more fully, thereby improving the microbial degradation efficiency.

[0037] Furthermore, the height of the long-axis blade 321 is greater than or equal to the distance from the stirring shaft 310 to the upper layer of the padding, and is equal to the distance from the stirring shaft 310 to the semicircular bottom 210, that is, when the blade 324 of the long-axis blade 321 is at the highest point, it can contact the human excrement falling on the upper layer of the padding and mix the human excrement with the padding. When the blade 324 of the long-axis blade 321 is located in the semicircular bottom 210, the blade 324 is close to the inner wall of the semicircular bottom 210 to eliminate the mixing blind spots and dead angles as much as possible and reduce odor emissions. The blade 324 is in an arc shape to cooperate with the semicircular bottom 210 to fully mix the human excrement with the padding, thereby increasing the degradation rate of microorganisms, reducing the residence time of human excrement, and effectively reducing odor emissions. For another example, crushing blades are provided on both sides of the blade 324 to crush relatively dry human excrement, so that microorganisms can fully contact with human excrement, thereby increasing the degradation rate of microorganisms, reducing the residence time of human excrement, and effectively reducing odor emissions.

[0038] Please also see Figure 6 and Figure 7 Furthermore, the stirring shaft 310 is also provided with a plurality of spiral transverse mixing blades 311, and the transverse mixing blades 311 are arranged between two adjacent stirring blades 320. When the stirring shaft drives the stirring blades 320 to rotate, the stirring blades 320 disturb the pad in a direction perpendicular to the stirring shaft 310. The transverse mixing blades 311 rotate with the stirring shaft 310, and push the pad in a direction parallel to the stirring shaft 310. At the same time, the pad is blocked by the stirring blades 320 and rolls between two adjacent stirring blades 320, thereby realizing the disturbance of the pad in a three-dimensional direction, so that the human excrement is fully dispersed in the pad, reducing the presence of local large particles, thereby effectively improving the degradation efficiency of microorganisms, reducing the residence time of human excrement, and reducing odor emissions.

[0039] Please continue to see Figure 5In a preferred embodiment, the waterless environmentally friendly toilet 10 further includes a urine separation component 700, and the urine separation component 700 includes a urine separation tank 710 and a urine collection box 720, wherein the urine separation tank 710 is arranged at the inner front end of the toilet body 100, and the urine collection box 720 is arranged at the outer side of the toilet body 100, and is connected to the urine separation tank 710 through a urine catheter. When the user is defecating, the urine separation tank collects the user's urine and introduces it into the urine collection box 720 for treatment through the urine catheter. Separating urine from the system can effectively reduce the volume of the microbial degradation chamber 200 on the one hand, and prevent excessive water from entering the microbial degradation chamber 200 on the other hand, causing the pad to be soaked in water for a long time to deteriorate and mold, affecting the activity of microorganisms.

[0040] Furthermore, the urine collection box 720 is inoculated with urine-degrading microorganisms to degrade organic matter contained in the urine. When the organic matter in the urine is degraded, the remaining water can be used as reclaimed water.

[0041] Furthermore, a splash guard is provided on the inner wall of the urine separation tank 710, and the splash guard may be a flexible material with pores, such as a rubber pad, a multi-layer nylon mesh, etc.

[0042] In another preferred embodiment, in order to further reduce the impact of odor on users and to replenish air into the microbial degradation chamber 200, a ventilation pipe 110 is provided on the toilet body 100, and the ventilation pipe 110 is connected to the microbial degradation chamber 200. The ventilation pipe 110 includes an air inlet pipe 111 and an odor exhaust pipe 112. The odor exhaust pipe 112 is connected to a negative pressure fan, so that the negative pressure fan can suck and replace the gas phase environment in the microbial degradation chamber 200, exhaust the odor, and replenish air, which can help to increase the microbial degradation rate.

[0043] Furthermore, the outlet of the negative pressure fan is connected to an auxiliary sterilization tube, and the inner wall of the auxiliary sterilization tube is attached with beneficial bacteria for further deodorization and sterilization. The odorous gas extracted by the negative pressure fan is discharged after passing through the auxiliary sterilization tube, further reducing the odor and reducing environmental pollution. The pathogens or other microorganisms contained in the odorous gas after passing through the auxiliary sterilization tube are further deodorized by beneficial microorganisms and the pathogens are reduced before being discharged, effectively preventing the spread of pathogens, thereby reducing environmental risks, health risks and safety risks.

[0044] Furthermore, the toilet body 100 is provided with a cover 120, and the cover 120 is sealed with the toilet body 100 by a sealing strip to prevent the odor that may exist in the microbial degradation chamber 200 from spreading from above the toilet body 100 and affecting the user.

[0045] In another specific embodiment, a control box 130 is further provided on the toilet body 100, and a microcontroller is installed in the control box 130, and the microcontroller has at least one input terminal and at least one output terminal. An input panel is provided on the control box 130, and the input panel is electrically connected to the input terminal of the microcontroller, and the output terminal of the microcontroller is respectively connected to the relay switch of the drive motor 330 of the mixing and stirring device 300, the relay switch of the negative pressure fan, and the relay switch of the temperature control circuit for adjusting the temperature, so that the user can control the opening and closing of the drive motor 330 of the mixing and stirring device 300, the negative pressure fan, and the temperature control circuit by operating the input panel.

[0046] Furthermore, a temperature sensor is provided in the microbial degradation chamber 200, the temperature sensor is electrically connected to the microcontroller, and the temperature sensor detects the temperature in the microbial degradation chamber 200. When the temperature in the microbial degradation chamber 200 is lower than the minimum threshold, the temperature control circuit is started to heat the microbial degradation chamber 200 to automatically maintain the activity of microorganisms at all times. For example, the temperature control circuit can adjust the output power, so as to automatically adjust the output power of the temperature control circuit according to the temperature in the microbial degradation chamber 200, so that the temperature in the microbial degradation chamber 200 is maintained at a state of high microbial activity.

[0047] What is disclosed above is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
