Description

Technical Field

[0001] The utility model relates to the technical field of toilet parts, in particular to a dry-wet separation structure applicable to a toilet and a biodegradable toilet. Background Art

[0002] The biodegradable toilet is a new type of toilet that has emerged in recent years and can degrade human excrement through microorganisms. It is particularly suitable for use in some indoor environments such as RVs, yachts, and the care of the elderly with limited mobility in nursing homes, where it is inconvenient to connect to water or discharge dirt.

[0003] Please refer to Chinese patents with publication numbers CN220735262U and CN219374488U, etc. In existing biodegradable toilets, urine and feces are usually directly discharged into a biodegradable container for biodegradation reaction. However, it has been found through research that the culture medium in the biodegradable container will undergo an anaerobic reaction due to excessive humidity and produce toxic and harmful gases, threatening the health of users.

[0004] Therefore, please refer to the Chinese utility model patent with publication number CN219527847U. A biodegradable toilet with a water receiving tray has emerged on the market. By setting a rotatable water receiving tray, urine or flushing water can be collected and guided into the urine tank, thus ensuring the dryness of the biodegradable container and avoiding the anaerobic reaction that produces toxic and harmful gases due to excessive humidity of the culture medium. However, the applicant has found in application that the water receiving tray and its auxiliary mechanisms will occupy a large amount of space in the biodegradable container, restricting the volume of the biodegradable container, resulting in the need to frequently replace the culture medium in the biodegradable container and seriously affecting the user experience.

[0005] Solving the above problems has become an urgent task. Content of the Utility Model

A sliding urine guide plate capable of sliding back and forth along the fixed urine guide plate is installed on the fixed urine guide plate;

[0009] When the sliding urine guide plate slides backward to the limit position, the front edge of the sliding urine guide plate is located between the front edge and the rear edge of the fixed urine guide plate, and the urine guide holes are exposed.

[0036] The present utility model will be further described below in conjunction with the embodiments and the drawings.

[0037] Embodiment 1:

[0038] As Figures 1 - 3 and Figure 13 shown, a dry-wet separation structure applicable to a toilet mainly includes a biodegradable container 2 with an open top, that is, the biodegradable container 2 is a box-shaped structure with an open top.

[0039] In this embodiment, a fixed urine guide plate 6 is fixedly installed at the front end of the open top of the biodegradable container 2. A urine guide hole 6a1 is opened on the fixed urine guide plate 6. The bottom of the urine guide hole 6a1 is connected to a urine tank 2h located below it through a urine guide pipeline 8. A sliding urine guide plate 7 that can slide back and forth along it is installed on the fixed urine guide plate 6.

[0040] Therefore, when the user defecates, the sliding urinary catheter plate 7 slides forward to the limit position. At this time, the sliding urinary catheter plate 7 overlaps above the fixed urinary catheter plate 6, so that the sliding urinary catheter plate 7 will not block the falling of feces, and the feces can directly enter the composting chamber 2b of the biodegradable container 2 and undergo a biodegradation reaction under the action of the culture medium. When the user urinates, when the sliding urinary catheter plate 7 slides backward to the limit position, the front edge of the sliding urinary catheter plate 7 is located between the front edge and the rear edge of the fixed urinary catheter plate 6, and the urine guiding hole 6a1 is exposed. At this time, the sliding urinary catheter plate 7 and the fixed urinary catheter plate 6 cooperate to reliably catch the urine discharged by the user and transport the urine to the urine tank 2h through the urine guiding hole 6a1 and the urine guiding pipeline 8. The dry-wet separation structure applicable to the toilet occupies extremely little space of the biodegradable container 2, and the influence on the space of the biodegradable container 2 can be ignored, thus greatly extending the replacement frequency of the culture medium and improving the user experience.

[0041] It should be noted that the opening and storage of the sliding urinary catheter plate 7 do not necessarily need to slide to the limit position, as long as it can reliably catch urine or not block the excretion of feces. Moreover, the sliding of the sliding urinary catheter plate 7 can be manually controlled, that is, directly push and pull the sliding urinary catheter plate 7, which is simple, reliable and low-cost. The sliding urinary catheter plate 7 can also be electrically controlled. In this embodiment, the sliding of the sliding urinary catheter plate 7 is preferably electrically controlled. Specifically, a urinary catheter plate driving device 9 for driving the sliding urinary catheter plate 7 to slide back and forth is installed on the fixed urinary catheter plate 6. The urinary catheter plate driving device 9 can be a conventional method such as an electric push rod and a motor cooperating with a belt or a timing belt drive, as long as it can reliably control the sliding of the sliding urinary catheter plate 7.

[0042] In this embodiment, the fixed urinary catheter plate 6 includes a fixed plate main body 6a, which is arranged horizontally. A urine blocking plate 6c extending upward is provided at the front edge of the fixed plate main body 6a. The urine guiding hole 6a1 is opened at the middle position of the front end of the fixed plate main body 6a and is adjacent to the urine blocking plate 6c, so that the liquid can be gathered into the urine guiding hole 6a1 as much as possible. At the same time, the sliding urinary catheter plate 7 includes a sliding plate main body 7a slidably installed on the upper surface of the fixed plate main body 6a. Both the fixed plate main body 6a and the sliding plate main body 7a are inclined downward gradually from back to front, and both the fixed plate main body 6a and the sliding plate main body 7a are gradually deepened from both left and right sides to the middle position, so that the liquid on the fixed plate main body 6a and the sliding plate main body 7a can all gather towards the urine guiding hole 6a1, reducing the liquid residue on the fixed plate main body 6a and the sliding plate main body 7a.

[0043] Further, the leading edge of the fixing plate main body 6a is a circular arc structure protruding forward, the urine blocking plate 6c is a circular arc structure matching the leading edge of the fixing plate main body 6a, and the urine guiding hole 6a1 is located at the forefront of the leading edge of the fixing plate main body 6a, which can further guide all the liquid into the urine guiding hole 6a1 and reduce the liquid residue on the fixing plate main body 6a.

[0044] Further, inner sliding fit plates 6b extending downward are provided on the outer edges of the left and right sides of the fixing plate main body 6a, and the inner sides of the two inner sliding fit plates 6b are fixedly connected to the outer side wall of the biodegradable container 2, so that the fixed urine guiding plate 6 can be reliably installed on the biodegradable container 2. At the same time, outer sliding fit plates 7b extending downward are provided on the outer edges of the left and right sides of the sliding plate main body 7a, and the two outer sliding fit plates 7b are respectively arranged on the outer sides of the corresponding inner sliding fit plates 6b in a sliding fit manner, ensuring the reliability of the sliding fit between the fixed urine guiding plate 6 and the sliding urine guiding plate 7.

[0045] Further, a fixing plate relief groove 6a2 is formed by concave inward at the middle position of the trailing edge of the fixing plate main body 6a, and a sliding plate relief groove 7a1 adapted to the fixing plate relief groove 6a2 is formed by concave inward at the middle position of the trailing edge of the sliding plate main body 7a. Through such a design, when the user defecates, it can be avoided that the feces scrape on the fixed urine guiding plate 6 and the sliding urine guiding plate 7, ensuring the cleanliness of the fixed urine guiding plate 6 and the sliding urine guiding plate 7 and improving the user experience.

[0046] Please refer to Figure 1 , the dry-wet separation structure applicable to the toilet in this embodiment further includes a gray water tank 11. A gray water tank water inlet pipe 12 is connected to the gray water tank 11. A sliding diversion mechanism 10 is provided on the biodegradable container 2. The sliding diversion mechanism 10 includes a horizontal sliding frame 10a installed on the biodegradable container 2, a sliding water receiving box 10b slidably installed on the horizontal sliding frame 10a in the horizontal direction, and a water receiving box driving device 10c for driving the sliding water receiving box 10b to slide. The sliding water receiving box 10b is a box-shaped structure with an open upper part. The urine guiding pipeline 8 includes an upper urine guiding pipe 8a and a lower urine guiding pipe 8b distributed up and down. The upper end of the upper urine guiding pipe 8a is communicated with the bottom of the urine guiding hole 6a1, and the lower end of the upper urine guiding pipe 8a extends downward into the sliding water receiving box 10b. The lower end of the lower urine guiding pipe 8b is communicated with the urine tank 2h, and the inlet at the upper end of the lower urine guiding pipe 8b and the inlet at the upper end of the gray water tank water inlet pipe 12 are arranged side by side below the sliding water receiving box 10b. A water pipe joint 10b1 extending downward is provided at the bottom of the sliding water receiving box 10b, and the water receiving box driving device 10c can drive the sliding water receiving box 10b to slide so that the water pipe joint 10b1 is communicated with the inlet at the upper end of the lower urine guiding pipe 8b or the inlet at the upper end of the gray water tank water inlet pipe 12.

[0047] With such a design, when the user is flushing, the water receiving box driving device 10c controls the water pipe joint 10b1 to communicate with the inlet at the upper end of the gray water tank inlet pipe 12, so that relatively clean liquid can be collected into the gray water tank 11 for use in some domestic water usage scenarios. When the user urinates, the water receiving box driving device 10c controls the water pipe joint 10b1 to communicate with the inlet at the upper end of the lower urinary catheter 8b, so that urine can be introduced into the urine tank 2h for storage. Therefore, the design of separate collection not only reduces the pressure of daily water use, but also reduces the pressure of urine treatment.

[0048] Furthermore, the horizontal sliding carriage 10a includes a carriage bracket and a guide rail installed on the carriage bracket. The sliding water receiving box 10b cooperates with the guide rail through the sliding support rollers 10b2, so that it can move horizontally along the guide rail, which is simple and reliable. At the same time, the water receiving box driving device 10c can adopt an electric push rod installed in the horizontal direction, which can directly drive the sliding water receiving box 10b to move.

[0049] In this embodiment, please refer to Figure 2 , on each of the left and right sides of the biodegradable container 2, a urine tank 2h is integrated. The integration degree is high, the space occupation is small, and the volume of the urine tank 2h can be as large as possible. And, a cold evaporation mechanism 13 is installed on the biodegradable container 2. The cold evaporation mechanism 13 includes an inlet air blower 13a, an exhaust air blower 13b, an inlet air pipe 13c and an exhaust air pipe 13d. The inlet air blower 13a and the exhaust air blower 13b are both installed on the biodegradable container 2. The air inlet of the inlet air pipe 13c is communicated with the air outlet of the inlet air blower 13a, the air outlet of the inlet air pipe 13c is communicated with the air inlets of the two urine tanks 2h, the air inlet of the exhaust air pipe 13d is communicated with the air outlets of the two urine tanks 2h, and the air outlet of the exhaust air pipe 13d is communicated with the air inlet of the exhaust air blower 13b.

[0050] The exhaust air blower 13b continuously sends fresh air from the outside into the two urine tanks 2h through the inlet air pipe 13c. At the same time, the exhaust air blower 13b continuously exhausts the inside of the two urine tanks 2h through the exhaust air pipe 13d, so as to realize cold evaporation of the urine in the two urine tanks 2h.

[0051] And, the air outlet of the exhaust air blower 13b is communicated with the exhaust pipe of the RV through the external exhaust pipe 13b1, which can avoid the appearance of urine odor inside the RV.

[0052] Furthermore, ultraviolet disinfection lamps are also provided in the two urine tanks 2h, which can effectively sterilize the urine in the two urine tanks 2h.

[0053] Embodiment 2:

[0054] A biodegradable toilet, including the dry-wet separation structure applicable to the toilet in Embodiment 1. The interior of the biodegradable container 2 is divided by a partition plate 2a into a compost chamber 2b and an emission chamber 2c which are distributed up and down. A stirring kettle 4 capable of rotating along it is installed in the compost chamber 2b. The stirring kettle 4 is rotatably installed at the bottom of the compost chamber 2b. The partition plate 2a is an arc-shaped structure adapted to the stirring kettle 4, that is: the double spiral blades 4b1 of the stirring kettle 4 can rotate relative to the partition plate 2a in a state of being in contact or maintaining a micro-gap, so as to stir the culture medium in the compost chamber 2b.

[0055] Moreover, the partition plate 2a is provided with a waste discharge slit 2a1 communicating the compost chamber 2b and the emission chamber 2c. The waste discharge slit 2a1 extends along the length direction of the emission chamber 2c. A screw auger 1 is rotatably installed in the emission chamber 2c. The emission chamber 2c is a cylindrical cavity structure adapted to the screw auger 1, so as to be able to reduce the residues in the emission chamber 2c and improve the conveying efficiency of the screw auger 1 at the same time. One end of the emission chamber 2c is provided with a waste discharge port 2d, and the residue is discharged from the waste discharge port 2d. At the same time, a stirring kettle control device 5 for driving the stirring kettle 4 to rotate and a screw auger control device 3 for driving the screw auger 1 to rotate are installed on the biodegradable container 2.

[0056] The stirring kettle 4 has the following three implementation manners:

[0057] Please refer to Figure 8 and Figure 15 , the stirring kettle 4 mainly includes a stirring kettle rotating shaft 4a and stirring kettle cutters 4b arranged in a spiral shape on the outer peripheral surface of the stirring kettle rotating shaft 4a. Among them, the stirring kettle rotating shaft 4a can be a hollow shaft structure or a solid shaft structure.

[0058] In this embodiment, the stirring kettle cutters 4b each include double spiral blades 4b1 and blade brackets 4b2 arranged at both ends of the double spiral blades 4b1. Both ends of the double spiral blades 4b1 are respectively installed on the stirring kettle rotating shaft 4a through the corresponding blade brackets 4b2, that is: the double spiral blades 4b1 are arranged on the circumferential outer side of the stirring kettle rotating shaft 4a. By rotating the stirring kettle rotating shaft 4a, the culture medium can be stirred by the double spiral blades 4b1. Moreover, since each stirring kettle cutter 4b is arranged in a spiral shape, when the stirring kettle 4 rotates, while driving the culture medium to be turned and stirred, it can be conveyed from one end to the other end. Furthermore, by continuously switching the forward and reverse rotations of the stirring kettle 4, the two-way back-and-forth conveying of the culture medium can be realized, and the stirring ability is excellent, greatly improving the stirring efficiency of the culture medium, thereby improving the biodegradation speed of the culture medium.

[0059] Moreover, each double - helix blade 4b1 is composed of a first helix segment 4b11 and a second helix segment 4b12 connected in sequence. Both the first helix segment 4b11 and the second helix segment 4b12 are thin - sheet structures extending in a spiral shape, and the helix directions of the first helix segment 4b11 and the second helix segment 4b12 are opposite. In this embodiment, by designing the double - helix blade 4b1 to be composed of the first helix segment 4b11 and the second helix segment 4b12 with opposite helix directions, it can effectively stir the culture medium at the end of the biodegradable container while pushing the culture medium at the end towards the other end, avoiding the solidification of the culture medium at the end, thereby further enhancing the biodegradation rate and avoiding the generation of toxic and harmful gases due to anaerobic reactions.

[0060] In this embodiment, the blade support 4b2 has the following two structures:

[0061] Blade support 4b2 Structure One: The blade supports 4b2 located between adjacent double - helix blades 4b1 each include a support base 4b21 adapted to the stirring kettle rotating shaft 4a and two blade support rods 4b22 fixed on the support base 4b21. That is, two blade support rods 4b22 are provided on one support base 4b21, and the two blade support rods 4b22 are respectively connected to different double - helix blades 4b1.

[0062] Blade support 4b2 Structure Two: The blade supports 4b2 located at both ends of the stirring kettle rotating shaft 4a each include a support base 4b21 adapted to the stirring kettle rotating shaft 4a and one blade support rod 4b22 fixed on the support base 4b21. That is, for the two blade supports 4b2 located at both ends of the stirring kettle rotating shaft 4a, one blade support rod 4b22 is provided on one support base 4b21.

[0063] Therefore, by setting the blade support 4b2 Structure One, adjacent double - helix blades 4b1 share the same blade support 4b2, which is not only easy to assemble, but also reduces the cost of components, and is also conducive to the position matching between adjacent double - helix blades 4b1.

[0064] Furthermore, the support base 4b21 is detachably installed on the stirring kettle rotating shaft 4a. In this embodiment, the support base 4b21 is preferably detachably installed on the stirring kettle rotating shaft 4a by bolts, which is simple, reliable, and easy to assemble and disassemble.

[0065] Furthermore, both ends of the double - helix blade 4b1 are bent to form connection and cooperation parts 4b13 that are respectively detachably connected to the outer ends of the corresponding blade support rods 4b22, ensuring the convenience of their assembly. At the same time, in this embodiment, the connection and cooperation parts 4b13 are preferably connected by being respectively riveted to the outer ends of the corresponding blade support rods 4b22, which is simple, reliable, and can minimize the interference with stirring as much as possible.

[0066] Generally speaking, the stirring kettle 4 of this embodiment is assembled by four components. The structure of each component is very simple, easy to process and form, and the cost is low. At the same time, each component can be flexibly removed when damaged or in need of maintenance, and the installation after completion is also very convenient. Especially after long-term use, each component can be removed and separately cleaned and maintained, so that the stirring efficiency of the stirring kettle 4 can be maintained for a long time.

[0067] Embodiment 2 of the stirring kettle 4:

[0068] Please refer to Figure 9 , the main structure of this embodiment is exactly the same as that of Embodiment 1 of the stirring kettle 4. The difference is that both ends of the double-helix blade 4b1 are fixed to the outer ends of the corresponding blade support rods 4b22 by welding process. Compared with Embodiment 1 of the stirring kettle 4, the process requirements are relatively higher, and the welds are more likely to break after long-term use. At the same time, when the double-helix blade 4b1 or the blade support 4b2 is damaged, the difficulty of replacement and maintenance is also higher.

[0069] It should be noted that each double-helix blade 4b1 can also be integrally formed with each blade support 4b2, but the process difficulty is very high and the cost is relatively high.

[0070] Embodiment 3 of the stirring kettle 4:

[0071] Please refer to Figure 10 , the main structure of this embodiment is exactly the same as that of Embodiment 1 of the stirring kettle 4. The difference is that the blade supports 4b2 are all strip-shaped thin plate structures extending radially along the stirring kettle rotating shaft 4a. The inner ends of the blade supports 4b2 are welded and fixed to the stirring kettle rotating shaft 4a. The double-helix blade 4b1 is integrally formed with the blade supports 4b2 at both ends or is fixedly connected to the outer ends of the corresponding blade supports 4b2 by welding process. This embodiment is the same as Embodiment 2 of the stirring kettle 4. The welds are likely to break after long-term use. At the same time, the difficulty of replacement and maintenance of the stirring kettle rotating shaft 4a and the stirring kettle tool 4b is also higher.

[0072] The stirring kettle control device 5 has the following two implementation methods:

[0073] Embodiment 1 of the stirring kettle control device 5:

[0074] Please refer to Figure 2 and Figure 4, the stirring kettle control device 5 is a stirring kettle drive motor installed on one side wall of the biodegradation container 2. After the motor shaft of the stirring kettle drive motor penetrates into the composting chamber 2b, it can be directly coaxially fixed to one end of the stirring kettle rotating shaft 4a. Therefore, the motor shaft of the stirring kettle drive motor can drive the stirring kettle rotating shaft 4a to rotate synchronously with it, or it can be coaxially fixed to one end of the stirring kettle rotating shaft 4a through a coupling. The electric drive method is more labor-saving and has a high degree of automation.

[0075] Embodiment 2 of the stirring kettle control device 5:

[0076] The stirring kettle control device 5 is a hand crank (not shown in the figure) rotatably installed on one side wall of the biodegradation container 2. After the connecting shaft of the hand crank penetrates into the composting chamber 2b, it can be directly coaxially fixed to one end of the stirring kettle rotating shaft 4a, or it can be coaxially fixed to one end of the stirring kettle rotating shaft 4a through a coupling. Therefore, the connecting shaft of the hand crank can drive the stirring kettle rotating shaft 4a to rotate synchronously with it. The hand-crank drive method has a lower cost.

[0077] The screw auger 1 has the following two implementation modes:

[0078] Embodiment 1 of the screw auger 1:

[0079] Please refer to Figure 11 and Figure 14 , the screw auger 1 includes a screw shaft 1a and screw blades 1b arranged in a spiral shape on the outer peripheral surface of the screw shaft 1a. Among them, the screw shaft 1a can be a hollow shaft structure or a solid shaft structure. The screw shaft 1a and the screw blades 1b form a conventional screw auger.

[0080] In this embodiment, a leak-proof baffle 1c extending along the axial direction of the screw shaft 1a is fixedly connected to the outer edge of the screw blade 1b. The leak-proof baffle 1c is an arc-shaped sheet structure and is adapted to the waste discharge slit 2a1. Moreover, the axis line of the leak-proof baffle 1c coincides with the axis line of the screw shaft 1a.

[0081] The distance between the outer edge of each position of the screw blade 1b and the axis line of the screw shaft 1a is equal. The leak-proof baffle 1c is fixed to the outer edge of the screw blade 1b by a welding process. Therefore, through the overall rotation of the screw auger 1, the function of conveying materials can be realized. At the same time, by setting the leak-proof baffle 1c, the waste discharge slit 2a1 can be blocked when it stops rotating. It should be noted that the leak-proof baffle 1c is usually fixed to the screw blade 1b by a welding process, and the process is simple and easy to manufacture. Of course, the screw shaft 1a, the screw blades 1b and the leak-proof baffle 1c can also be integrally formed by a casting process, and the structural strength is higher.

[0082] Furthermore, the width of the leakage-preventing baffle 1c along the circumferential direction of the auger shaft 1a is consistent in each part, which is not only easy to process, but also the leakage-preventing baffle 1c is preferably made as narrow as possible, as long as it can just block the waste discharge slit 2a1, so as to minimize the impact on the feeding efficiency of the screw auger 1.

[0083] In this embodiment, the distance between the outer edge of each position of the auger blade 1b and the axis line of the auger shaft 1a is equal. The leakage-preventing baffle 1c is fixed on the outer edge of the auger blade 1b by a welding process. The process is simple and easy to manufacture. Moreover, the thickness of the leakage-preventing baffle 1c can be made very thin, so that the impact on the feeding efficiency of the screw auger 1 is smaller.

[0084] Screw auger 1 Embodiment 2:

[0085] Please refer to Figure 12 , the main structure of this embodiment is exactly the same as that of the screw auger 1 Embodiment 1. The difference is that: a plurality of blade mounting grooves 1b1 adapted to the leakage-preventing baffle 1c are formed by recessing the outer edge of the auger blade 1b. The leakage-preventing baffle 1c is snapped into each blade mounting groove 1b1 and fixed by a welding process. The distance between the outer edge of the auger blade 1b where there is no blade mounting groove 1b1 and the axis line of the auger shaft 1a is equal to the distance between the outer surface of the leakage-preventing baffle 1c and the axis line of the auger shaft 1a, so that the outer circumference of the screw auger 1 fits better with the inner wall of the space where the screw auger 1 is located, and the feeding efficiency of the screw auger 1 can be improved; moreover, the leakage-preventing baffle 1c of this embodiment not only has higher installation reliability, but also is less impacted when rotating, so that the leakage-preventing baffle 1c is not easily deformed and the service life is extended.

[0086] Regarding the leakage-preventing baffle 1c and the waste discharge slit 2a1, the length of the waste discharge slit 2a1 is less than or equal to the length of the leakage-preventing baffle 1c, and the width of the waste discharge slit 2a1 is less than or equal to the width of the leakage-preventing baffle 1c. Most importantly, when the screw auger 1 stops rotating, the auger control device 3 rotates the leakage-preventing baffle 1c to directly below the waste discharge slit 2a1, so that the leakage-preventing baffle 1c blocks the waste discharge slit 2a1.

[0087] Therefore, when the auger control device 3 drives the spiral auger 1 to rotate, the waste in the composting chamber 2b can continuously fall into the discharge chamber 2c through the waste discharge slot 2a1. At the same time, through the rotation of the spiral auger 1, the waste in the discharge chamber 2c can be discharged outwards through the waste discharge port 2d. Compared with the prior art, the whole process is not only simple and convenient to operate, but also greatly improves the user experience. Moreover, when waste discharge is not required, the leak-proof baffle 1c can reliably block the waste discharge slot 2a1, thereby avoiding the hardening and caking of the culture medium and fertilizer in the discharge chamber for a long time, which may cause the spiral auger 1 to jam or fail to rotate, resulting in difficulties in using the spiral auger 1. Furthermore, it can ensure the long-term reliable and stable operation of the spiral auger 1 and reduce the maintenance frequency of the spiral auger 1.

[0088] Further, please refer to Figure 4 , the partition plate 2a forms at least one connecting bridge 2a2 distributed along the length direction of the waste discharge slot 2a1 in the waste discharge slot 2a1. Both ends of each connecting bridge 2a2 are combined with the partition plate 2a on both sides in the width direction of the waste discharge slot 2a1, which can effectively avoid the problem of deformation of the waste discharge slot 2a1, thereby avoiding interference with the rotation of the auger blade 1b and the leak-proof baffle 1c in the lower discharge chamber 2c and the agitator 4 in the upper composting chamber 2b, and reducing the maintenance frequency.

[0089] Further, the waste discharge slot 2a1 is opened at the middle position of the partition plate 2a, which is also the lowest position of the partition plate 2a, so as to better discharge waste and improve the waste discharge efficiency.

[0090] Please refer to Figure 5 , a waste discharge pipe 2e communicating with the discharge chamber 2c is provided on one side wall of the biodegradation container 2. The waste discharge pipe 2e constitutes the waste discharge port 2d. The outlet end of the waste discharge pipe 2e is provided with a coaxial auger shaft support seat 2f. One end of the auger shaft 1a is rotatably installed on the auger shaft support seat 2f. The auger shaft support seat 2f is fixedly connected to the pipe wall of the waste discharge pipe 2e through a plurality of connecting ribs 2g evenly distributed along its circumference, thereby ensuring the reliable installation of the leak-proof spiral auger.

[0091] Finally, it should be noted that the above description is only the preferred embodiment of the present invention. Under the inspiration of the present invention, those of ordinary skill in the art can make various similar representations without violating the purpose and claims of the present invention. Such transformations all fall within the protection scope of the present invention.
