Description

Technical Field

[0001] The utility model relates to the technical field of toilet parts, in particular to a leak-proof spiral auger and a biodegradable toilet waste discharge structure. Background Art

[0002] Biodegradable toilets are a new type of toilet that has appeared in recent years. They can degrade human feces through microorganisms. They are particularly suitable for use in indoor environments such as RVs, yachts, and nursing homes for caring for elderly people with limited mobility where it is inconvenient to collect water or discharge waste.

[0003] Please refer to Chinese patents with publication numbers CN220735262U and CN219374488U. Existing biodegradable toilets only have a compost chamber for biodegradation reactions, which accelerates the biodegradation reaction of the culture medium on feces by stirring. When the reaction residue needs to be discharged, either the entire compost chamber can only be taken out for dumping, but because the stirring tank of the compost chamber is connected to the stirring tank drive device, the disassembly process is relatively troublesome; or the residue can only be discharged by manually scooping out the residue, which is not only very time-consuming and labor-intensive, but also the operation process is very likely to cause users to have physiological reactions such as nausea. Therefore, no matter which existing slag discharge method is adopted, the user experience is relatively poor, and the operation process is relatively difficult.

[0004] Solving the above problems has become a top priority. Utility Model Content

[0005] In view of this, the utility model provides a leak-proof spiral auger and a biodegradable toilet waste discharge structure.

[0006] The technical solution is as follows:

[0007] The first aspect of the present application relates to a leak-proof spiral auger, comprising an auger shaft and auger blades arranged on the outer peripheral surface of the auger shaft in a spiral extension. The outer edge of the auger blade is fixedly connected to a leak-proof baffle extending axially along the auger shaft. The leak-proof baffle is an arc-shaped sheet structure, and the axial center line of the leak-proof baffle coincides with the axial center line of the auger shaft.

[0008] The use of the above leak-proof spiral auger can not only realize the material conveying function through the overall rotation, but also can block the specific position when it stops by setting the leak-proof baffle.

[0009] In some embodiments, the distances between the outer edges of the auger blades at all positions and the axis of the auger shaft are equal, and the leak-proof baffles are fixed to the outer edges of the auger blades by welding.

[0010] In some embodiments, the outer edge of the auger blade is recessed to form a plurality of blade mounting grooves adapted to the leak-proof baffle. The leak-proof baffle is snapped into each blade mounting groove and fixed by a welding process. The distance between the outer edge of the auger blade where no blade mounting groove is provided and the axis of the auger shaft is equal to the distance between the outer surface of the leak-proof baffle and the axis of the auger shaft.

[0011] In some embodiments, the width of the leak-proof baffle along the circumferential direction of the auger shaft is consistent in each part.

[0012] The second aspect of the present application relates to a waste discharge structure of a biodegradable toilet, including a biodegradable container with an open upper part, the above-mentioned leak-proof auger, and an auger control device for driving the rotation of the auger shaft. The interior of the biodegradable container is divided into a compost chamber and a discharge chamber distributed vertically by a partition plate. The discharge chamber is a cylindrical cavity structure adapted to the leak-proof auger. A waste discharge port communicating with the discharge end of the discharge chamber is provided on the biodegradable container. A waste discharge slit communicating the compost chamber and the discharge chamber is provided on the partition plate. The waste discharge slit extends along the length direction of the discharge chamber and is adapted to the leak-proof baffle. When the leak-proof auger stops rotating, the auger control device rotates the leak-proof baffle to directly below the waste discharge slit to block the waste discharge slit.

[0013] With the above waste discharge structure of the biodegradable toilet, when the auger control device drives the leak-proof auger to rotate, the waste in the compost chamber can continuously fall into the discharge chamber through the waste discharge slit. At the same time, through the rotation of the leak-proof auger, the waste in the discharge chamber can be discharged out through the waste discharge port. 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 can reliably block the waste discharge slit, thus avoiding the hardening of the medium and fertilizer due to long-term presence in the discharge chamber, which may cause the leak-proof auger to jam or fail to rotate, and further ensuring the long-term reliable and stable operation of the leak-proof auger and reducing the maintenance frequency of the leak-proof auger.

[0014] In some embodiments, the auger control device is an auger drive motor installed on a side wall of the biodegradable container. After the motor shaft of the auger drive motor penetrates into the discharge chamber, it is coaxially fixed to the end of the auger shaft away from the waste discharge port.

[0015] In some embodiments, the auger control device is a manual rocker rotatably installed on a side wall of the biodegradable container. After the connecting shaft of the manual rocker penetrates into the discharge chamber, it is coaxially fixed to the end of the auger shaft away from the waste discharge port.

[0016] In some embodiments, at least one connecting bridge distributed along the length direction of the waste discharge slit is formed in the waste discharge slit of the partition plate. Both ends of each connecting bridge are combined with the partition plates on both sides in the width direction of the waste discharge slit.

[0017] In some embodiments, a waste discharge pipe communicating with the discharge cavity is provided on one side wall of the biodegradable container. The waste discharge pipe constitutes the waste discharge port. An auger shaft support seat coaxial with the waste discharge pipe is provided at the outlet end of the waste discharge pipe. One end of the auger shaft is rotatably installed on the auger shaft support seat, and the auger shaft support seat is fixedly connected to the pipe wall of the waste discharge pipe through a plurality of connecting ribs uniformly distributed along its circumferential direction.

[0024] The present utility model will be further described below in conjunction with the embodiments and the drawings.

[0025] Embodiment 1:

[0026] As Figure 1 shown, a leak-proof auger mainly includes an auger shaft 1a and an auger blade 1b spirally extending on the outer peripheral surface of the auger shaft 1a. Among them, the auger shaft 1a can be a hollow shaft structure or a solid shaft structure. The auger shaft 1a and the auger blade 1b constitute a conventional auger.

[0027] In this embodiment, a leak-proof baffle 1c extending along the axial direction of the auger shaft 1a is fixedly connected to the outer edge of the auger blade 1b. The leak-proof baffle 1c is an arc-shaped sheet structure, and the axis of the leak-proof baffle 1c coincides with the axis of the auger shaft 1a.

[0028] The distance between the outer edge of each position of the auger blade 1b and the axis of the auger shaft 1a is equal, and the leakage prevention baffle 1c is fixed on the outer edge of the auger blade 1b through a welding process. Therefore, through the overall rotation of this leakage prevention auger, the conveying function of materials can be realized. At the same time, by setting the leakage prevention baffle 1c, it can play a role in blocking specific positions when it stops rotating. For details, please refer to Embodiment 3. It should be noted that the leakage prevention baffle 1c is usually fixed on the auger blade 1b through a welding process, with a simple process and easy to manufacture. Of course, the auger shaft 1a, the auger blade 1b, and the leakage prevention baffle 1c can also be integrally formed through a casting process, with higher structural strength.

[0029] Furthermore, the width of the leakage prevention baffle 1c along the circumferential direction of the auger shaft 1a is the same for each part. It is not only easy to process, but also the leakage prevention baffle 1c is preferably made as narrow as possible, as long as it can just achieve the blocking function, so as to minimize the impact on the feeding efficiency of the leakage prevention auger.

[0030] In this embodiment, the distance between the outer edge of each position of the auger blade 1b and the axis of the auger shaft 1a is equal, and the leakage prevention baffle 1c is fixed on the outer edge of the auger blade 1b through a welding process. The process is simple and easy to manufacture. Moreover, the thickness of the leakage prevention baffle 1c can be made very thin, thus having a smaller impact on the feeding efficiency of the leakage prevention auger.

[0031] Embodiment 2:

[0032] Please refer to Figure 2 , the main structure of this embodiment is exactly the same as that of Embodiment 1. The difference lies in that: multiple blade mounting grooves 1b1 adapted to the leakage prevention baffle 1c are formed by recessing the outer edge of the auger blade 1b. The leakage prevention baffle 1c is snapped into each blade mounting groove 1b1 and fixed through a welding process. The distance between the outer edge of the auger blade 1b without the blade mounting groove 1b1 and the axis of the auger shaft 1a is equal to the distance between the outer surface of the leakage prevention baffle 1c and the axis of the auger shaft 1a, so that the circumferential outer edge of the leakage prevention auger fits better with the inner wall of the space where the leakage prevention auger is located, and the feeding efficiency of the leakage prevention auger can be improved; moreover, the leakage prevention baffle 1c in this embodiment not only has higher installation reliability, but also is less impacted when rotating, so that the leakage prevention baffle 1c is not easily deformed and the service life is extended.

[0033] Embodiment 3:

[0034] Please refer to Figures 1-6, A biodegradable toilet waste discharge structure, including a biodegradable container 2 with an open upper part, the leak-proof screw auger of Embodiment 1 or Embodiment 2, and a screw auger control device 3 for driving the rotation of the screw auger shaft 1a. Inside the biodegradable container 2, there are a composting chamber 2b and a discharge chamber 2c distributed vertically. The composting chamber 2b and the discharge chamber 2c are separated by a partition plate 2a.

[0035] Among them, the discharge chamber 2c is a cylindrical cavity structure adapted to the leak-proof screw auger, which can reduce the residues in the discharge chamber 2c and improve the conveying efficiency of the leak-proof screw auger at the same time. A waste discharge port 2d communicating with the discharge end of the discharge chamber 2c is opened on the biodegradable container 2, and the residue is discharged from the waste discharge port 2d. At the same time, a screw auger control device 3 for driving the screw auger 1 to rotate is installed on the biodegradable container 2.

[0036] A waste discharge slot 2a1 communicating the composting chamber 2b and the discharge chamber 2c is opened on the partition plate 2a. The waste discharge slot 2a1 extends along the length direction of the discharge chamber 2c, and the structure of the waste discharge slot 2a1 is adapted to the structure of the leak-proof flap 1c, that is: the length of the waste discharge slot 2a1 is less than or equal to the length of the leak-proof flap 1c, and the width of the waste discharge slot 2a1 is less than or equal to the width of the leak-proof flap 1c. Most importantly, when the leak-proof screw auger stops rotating, the screw auger control device 3 rotates the leak-proof flap 1c to directly below the waste discharge slot 2a1, so that the leak-proof flap 1c blocks the waste discharge slot 2a1.

[0037] Therefore, when the screw auger control device 3 drives the leak-proof screw auger 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 leak-proof screw auger, the waste in the discharge chamber 2c can be discharged out 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. And when waste discharge is not required, the leak-proof flap 1c can reliably block the waste discharge slot 2a1, thus avoiding the hardening of the medium and fertilizer due to long-term stay in the discharge chamber, resulting in the jamming or inability to rotate of the leak-proof screw auger, and causing difficulties in using the leak-proof screw auger. Furthermore, it can ensure the long-term reliable and stable operation of the leak-proof screw auger and reduce the maintenance frequency of the leak-proof screw auger.

[0038] Furthermore, please refer to Figure 3 , at least one connecting bridge 2a2 distributed along the length direction of the waste discharge slot 2a1 is formed in the waste discharge slot 2a1 of the partition plate 2a. 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 deformation of the waste discharge slot 2a1, thus avoiding interference with the rotation of the screw auger blade 1b and the leak-proof flap 1c in the lower discharge chamber 2c and the agitator in the upper composting chamber 2b, and reducing the maintenance frequency.

[0039] Furthermore, the partition plate 2a is an arc-shaped sheet structure protruding downward to better adapt to the rotation of the stirring kettle, so that the mixing in the stirring kettle is more sufficient, thereby improving the speed of biodegradation. Correspondingly, the waste discharge slit 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.

[0040] Please refer to Figure 4 , a waste discharge pipe 2e communicating with the discharge cavity 2c is provided on one side wall of the biodegradation container 2. The waste discharge pipe 2e constitutes a waste discharge port 2d. A screw shaft support seat 2f coaxial with it is provided at the outlet end of the waste discharge pipe 2e. One end of the screw shaft 1a is rotatably installed on the screw shaft support seat 2f. The screw 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, thus ensuring the reliable installation of the leak-proof screw auger.

[0041] Please refer to Figure 3 and Figure 5 , the screw auger control device 3 of this embodiment is a screw auger driving motor installed on one side wall of the biodegradation container 2. After the motor shaft of the screw auger driving motor penetrates into the discharge cavity 2c, it can be directly coaxially fixed to one end of the screw shaft 1a away from the waste discharge port 2d. Therefore, the motor shaft of the screw auger driving motor can drive the screw shaft 1a to rotate synchronously with it, or it can be coaxially fixed to one end of the screw shaft 1a away from the waste discharge port 2d through a coupling. The electric drive method is more labor-saving and has a high degree of automation.

[0042] Embodiment 4:

[0043] The main structure of this embodiment is exactly the same as that of Embodiment 3, and the difference lies in that: the screw auger control device 3 is a manual rocker (not shown in the figure) rotatably installed on one side wall of the biodegradation container 2. After the connecting shaft of the manual rocker penetrates into the discharge cavity 2c, it can be directly coaxially fixed to one end of the screw shaft 1a away from the waste discharge port 2d, or it can be coaxially fixed to one end of the screw shaft 1a away from the waste discharge port 2d through a coupling. Therefore, the connecting shaft of the manual rocker can drive the screw shaft 1a to rotate synchronously with it, and the manual drive method has a lower cost.

[0044] Finally, it should be noted that the above description is only the preferred embodiment of the present invention. Those of ordinary skill in the art can make various similar representations under the inspiration of the present invention without violating the purpose and claims of the present invention. Such transformations all fall within the protection scope of the present invention.
