Description

Technical Field

[0001] This utility model relates to the field of incineration toilet technology, and in particular to the ash water tank structure of an incineration toilet. Background Technology

[0002] International patent application WO2023139184A1 discloses an incineration toilet with a safety system, but the safety system in this application has room for further optimization. The incineration barrel and the exhaust vent connected to it are both fixed in position and cannot be moved, making it difficult to completely extract the particulate matter formed after the incineration of excrement, thus the ash extraction effect has room for improvement. Furthermore, the technical solution in this application has room for further optimization in terms of the internal spatial layout of the incineration toilet, the fixing effect of the incineration barrel, ease of operation, and the treatment of particulate matter formed by the incineration of excrement.

[0003] Chinese invention patent application CN119385446A discloses a sealing cover structure for an incinerator toilet. However, during actual assembly, it was found that the sliding wheel 28 needs to be installed onto the carrier 8 first and the alignment of the sliding wheel 28 needs to be maintained, which makes the installation of the front shaft complicated and leaves room for further optimization. Utility Model Content

[0004] One objective of this invention is to solve or alleviate the aforementioned technical problems.

[0005] The present invention employs a structure for an ash water tank incinerating a toilet, which includes an ash water tank; the ash water tank includes a connecting hose for inputting lumps or ash formed by the incineration of excrement, and an atmospheric communication pipe is provided at the top of the ash water tank body, with a filter element surrounding the atmospheric communication pipe.

[0006] The effect achieved by this utility model is that it can prevent excessive pressure and rupture of the grey water tank caused by the continuous introduction of gas containing lumps or ash into the grey water tank, while reducing the odorous substances that overflow from the atmospheric connection pipe.

[0007] A further technical solution is that the atmospheric connecting pipe is a rigid circular pipe with an annular protrusion extending into the bottom box. The filter element includes a rigid bottom ring and a rigid top cover. A filter body is disposed between the bottom ring and the rigid top cover. The annular protrusion fits snugly onto the atmospheric connecting pipe.

[0008] It facilitates the disassembly and installation of the filter elements.

[0009] A further technical solution involves using filter paper as the filter body.

[0010] To reduce odorous substances escaping from the atmospheric connection pipe.

[0011] A further technical solution involves making the outer diameter of the rigid top cover smaller than the outer diameter of the bottom ring.

[0012] A further technical solution involves installing a ash water discharge pipe on the bottom surface of the ash water tank; and installing a discharge valve on the ash water discharge pipe.

[0013] It allows for easy drainage of grey water from the grey water tank. Attached Figure Description

[0036] The accompanying drawings in the specification that best illustrate the technical features of this utility model are: Figure 16 . Detailed Implementation

[0037] The specific embodiments of this utility model will now be described with reference to the accompanying drawings.

[0038] As a specific embodiment, the improved incineration toilet of this utility model includes an incineration toilet 1 and an ash tank 9. The incineration toilet 1 includes a buffer structure 2, an incineration structure 3, an incineration barrel 4, an ash-absorbing structure 5, a mounting bracket 6, and an outer cover assembly 7. The buffer structure 2 includes a release element 22, an incineration sealing element 23, a release element carrier 28, and a buffer groove 21 with a release port 211. The release element 22 is hinged to the outer wall of the buffer groove 21 and completely covers the release port 211. Typically, the buffer groove 21 and the release element 22 are both made of bent sheet metal. The specific structure of the release element 22 and the buffer groove 21 is the same as the technical solution disclosed in CN119385446A, and will not be described again here.

[0039] Both sides of the incineration sealing member 23 are provided with a front shaft 231 and a rear shaft 232. The rear shaft 232 is hinged to a power arm 233, which has rotational power. The release member carrier 28 is provided with a front shaft groove 281 and a through groove 282. The front shaft 231 is embedded in the front shaft groove 281 and can slide along the front shaft groove 281, while the rear shaft 232 passes through the through groove 282. Of course, in the embodiment where the power arm 233 is located inside the release member carrier 28, the rear shaft 232 does not need to pass through the release member carrier 28, and therefore the through groove 282 is not required. There is a height difference between the front and rear ends of the front shaft groove 281. When the power arm 233 drives the incineration sealing member 23, the front end of the incineration sealing member 23 will generate a height difference, and the angle of the incineration sealing member 23 will also change, which is beneficial to improving its sealing performance to the bottom opening of the guide cover 32 described later. In general, the structures of the buffer slot 21, release element 22, incineration sealing element 23, and release element carrier 28 are the same as those disclosed in CN119385446A, except for the specific structures of the front shaft 231 and rear shaft 232. These details will not be elaborated further here. Typically, the incineration sealing element 23 is equipped with a sealing elastic element 239, which is a spring-loaded piece.

[0040] The incineration structure 3 includes an incineration hood 31, inside which a heating device (not shown in the attached diagram) is installed. Typically, a guide hood 32 is fixedly installed at the top of the incineration hood 31. The inner cavity of the guide hood 32 is a frustum-shaped structure with a larger diameter at the upper end and a smaller diameter at the lower end. The specific structures of the incineration hood 31, the guide hood 32, and the heating device are the same as those disclosed in CN119385446A, and will not be described again here.

[0041] The incineration barrel 4 is used to hold excrement and other waste falling from the release port of the buffer tank 21. It is located below the incineration hood 31 and its top end abuts against the bottom end of the incineration hood 31, so that the incineration barrel 4 and the incineration hood 31 form a sealed space. Typically, the incineration barrel 4 is equipped with a handle 49.

[0042] The ash-collecting structure 5 is used to transport the lumps formed after the incineration of excrement and other materials in the incineration barrel 4 to the ash water tank 9. It should be noted that the lumps formed after the incineration of excrement and other materials are usually relatively large in particle size. The ash-collecting structure 5 includes an ash-collecting hood 51 and a negative pressure device 52.

[0043] The mounting frame 6 is located inside the outer casing assembly 7 and is used to install the buffer structure 2, the incineration structure 3, and the ash-absorbing structure 5. Specifically, the mounting frame 6 includes a mounting base plate 61, mounting side plates 62, and mounting top plate 63 that are fixedly connected from bottom to top. Typically, there are two mounting side plates 62, so that the mounting base plate 61, the two mounting side plates 62, and the mounting top plate 63 form a rectangular frame.

[0044] Mounting bracket 6 also includes a slide plate 64 linearly slidably connected to mounting base plate 61, the slide plate 64 having linear power. For example, the slide plate 64 is linearly slidably connected to mounting base plate 61 via a linear guide rod 619 on mounting base plate 61. Mounting base plate 61 is provided with a transverse movement device 641, which is an electric cylinder and its output end is hinged to the hinge lug 615 of slide plate 64 by screws (not shown in the attached figure), so that slide plate 64 has linear power. The incineration barrel 4 is detachably placed on slide plate 64.

[0045] The ash-collecting hood 51 is disc-shaped and has lifting power, allowing it to be inserted into the inner cavity of the incineration barrel 4. A negative pressure device 52 is fixed to the mounting frame 6 and communicates with the ash-collecting hood 51. Specifically, the negative pressure device 52 is equipped with a suction pipe 521 and an ash discharge pipe 522. The suction pipe 521 is connected to the ash-collecting hood 51 via a flexible hose (not shown in the attached diagram). For example, a lifting device 511, which is an electric cylinder, is fixedly installed on the mounting frame 6 (e.g., on the top plate frame 635 for mounting the top plate 63). The output end of the lifting device 511 is connected to the ash-collecting hood 51, giving the ash-collecting hood 51 lifting power.

[0046] The outer cover assembly 7 surrounds the mounting bracket 6, which includes a side cover 71 and a rear cover 719. Typically, the outer cover assembly 7 also includes a toilet seat assembly 79 disposed at the top of the side cover 71. When the toilet seat of the toilet seat assembly 79 (not shown in the attached figure) is rotated open, the top of the buffer slot 21 is exposed, allowing a person to sit on the toilet seat assembly 79 for use.

[0047] As one specific implementation, the incineration toilet 1 includes an electronic control device with a timing function. A temperature sensor (not shown in the attached figure) electrically connected to the electronic control device is installed inside the cavity of the incineration hood 31. The electronic control device (e.g., a conventional circuit board, which has a timing function via a timing module) and the temperature sensor are both existing technologies, and their detailed technical solutions will not be elaborated further. An incineration rotation device 234 is fixedly installed on the mounting bracket 6. The incineration rotation device 234 is a geared motor, etc. The other end of the power arm 233 (the other end of the power arm 233 that is hinged to the rear shaft 232) is fixedly connected to the output end of the incineration rotation device 234, thus providing rotational power. The incineration rotating device 234 and the heating device are electrically connected to the electronic control device. The temperature read by the temperature sensor is the measured temperature. The period from the start to the stop of the heating device is the heating period. The period from the end of the heating device operation to the start of the incineration rotating device 234 driving the power arm 233 to open the incineration sealing member 23 is the delayed opening period. Specifically, the incineration method is as follows: After starting the heating device until the measured temperature reaches or exceeds a threshold and is maintained for a set period (e.g., the threshold is set to 700 degrees Celsius and maintained for 5 minutes), the heating device is stopped. The delayed opening period is determined based on the heating period (e.g., if the heating period is between 5 and 30 minutes, the delayed opening period is 30 minutes; if the heating period exceeds 30 minutes, the delayed opening period is 60 minutes, etc.). After the delayed opening period is reached, the electronic control device controls the incineration rotating device 234 to open the incineration sealing member 23. This ensures safety by preventing urine and other substances from entering the incineration barrel 4 during incineration and rapidly vaporizing, similar to an explosion. Unlike the technical solution disclosed in international application WO2023139184A1, the opening or closing of the incineration sealing component 23 is not affected regardless of whether the toilet seat of the outer cover assembly 7 is open or closed. Therefore, there is no need to install magnetic sensors or micro-switch lights on the toilet seat of the outer cover assembly 7, which simplifies the structure and reduces production and material costs.

[0048] The working principle is as follows: In use, the incineration barrel 4 is located below the incineration hood 31, with its top end abutting against the bottom surface of the incineration hood 31, thus forming a sealed space between the incineration barrel 4 and the incineration hood 31. As mentioned earlier, the heating device installed inside the incineration hood 31 heats the waste, such as excrement, falling into the incineration barrel 4, causing it to be heated to a high temperature and incinerated. After incineration, the waste forms lumps. Typically, the incineration barrel 4 is equipped with a conventional heat insulation layer to prevent the external temperature of the incineration barrel 4 from becoming too high when the waste is incinerated.

[0049] During the cleaning process, the sliding plate 64 moves towards the ash suction hood 51, completely disengaging the incineration barrel 4 from the incineration hood 31, and fully exposing the top opening of the inner cavity of the incineration barrel 4. The negative pressure device 52 is activated, and the ash suction hood 51 moves downwards and inserts into the inner cavity of the incineration barrel 4 until it is in contact with the bottom surface of the inner cavity, then rises. This process can be repeated several times, causing the lumps to be sucked into the suction pipe 521 and discharged from the ash discharge pipe 522 into the ash water tank 9, where they mix with the water (pre-filled into the ash water tank 9) to form ash water. The close proximity of the ash suction hood 51 to the lumps ensures that all the lumps in the incineration barrel 4 are sucked into the negative pressure device 52.

[0050] like Figure 5 , 6 As shown in Figure 14, the lifting ash suction port structure of the incineration toilet includes a mounting frame 6, an incineration barrel 4, a negative pressure device 52, and an ash suction hood 51 with lifting power. The inner cavity of the incineration barrel 4 is cylindrical or frustum-shaped.

[0051] After the sliding plate 64 moves the incinerator 4, the ash suction hood 51 descends and can fully extend into the inner cavity of the incinerator 4, that is, the ash suction hood 51 can fit against the bottom surface of the incinerator 4. The ash suction hood 51 clamps a portion of the blocky material with the bottom surface of the inner cavity of the incinerator 4, so that the blocky material is initially crushed, making it easier for the blocky material to be sucked in by the negative pressure device 52.

[0052] As one specific implementation, the inner cavity of the incinerator 4 is a frustum shape, wider at the top and narrower at the bottom. A lifting device 511, which is an electric cylinder, is fixedly installed on the mounting frame 6. The lifting device 511 is inclined and has the same inclination angle as the inner cavity sidewall of the incinerator 4. Figure 14 As shown, the right side wall of the cross-section of the incinerator 4 is located between the incinerator and the lifting device 511. It is easy to understand that the diameter of the ash suction hood 51 must be smaller than the diameter of the top surface of the inner cavity of the incinerator 4 in order to be fully inserted into the inner cavity of the incinerator 4. After the ash suction hood 51 is inserted into the inner cavity of the incinerator 4, the sliding plate 64 can drive the incinerator 4 to move back and forth slightly, which can improve the cleaning effect of the incinerator 4.

[0053] As one of the specific implementation methods, such as Figure 14As shown, the output end of the lifting device 511 is damped and hinged to the ash-collecting hood 51, allowing the ash-collecting hood 51 to swing. The ash-collecting hood 51 can rotate clockwise and counterclockwise within the plane of the drawing. A rubber sleeve is fitted between the hinge shaft of the lifting device 511 and the ash-collecting hood 51 to achieve damped hinged connection. Alternatively, a damped hinge can be achieved between the output end of the lifting device 511 and the ash-collecting hood 51 using a damping bearing. The ash-collecting hood 51 overcomes its own weight and maintains its posture due to damping force. The diameter of the ash-collecting hood 51 is smaller than the diameter of the bottom surface of the inner cavity of the incinerator 4 (i.e., the smaller side of the frustum-shaped structure). During the process of inserting the ash-collecting hood 51 into the inner cavity of the incineration barrel 4 until it is in contact with the bottom surface of the inner cavity of the incineration barrel 4, the sliding plate 64 can drive the incineration barrel 4 to move back and forth slightly, which can improve the cleaning effect of the incineration barrel 4. Even if the inner wall of the incineration barrel 4 abuts against the ash-collecting hood 51 and causes the ash-collecting hood 51 to swing, after the ash-collecting hood 51 is in contact with the bottom surface of the inner cavity of the incineration barrel 4, the ash-collecting hood 51 returns to a roughly horizontal position. Then the ash-collecting hood 51 rises and resets, which can ensure the stable ash-collecting effect of the ash-collecting hood 51.

[0054] like Figure 5 , 8 As shown, the incinerator pot locking structure includes an incineration hood 31, a mounting bracket 6, and a cylindrical incineration barrel 4.

[0055] At least two positioning bodies 643 are fixedly installed at the rear end of the slide plate 64, and an elastic stop bar 66 is provided at the front end of the slide plate 64. The elastic stop bar 66 has an upward tendency to move. The incineration barrel 4 is placed on the slide plate 64, and the elastic stop bar 66 and the two positioning bodies 643 are respectively attached to the outer wall of the incineration barrel 4, so that the incineration barrel 4 can be detachably placed on the slide plate 64. The rear end of the incineration barrel 4 is first placed on the slide plate 64, so that the bottom end surface of the incineration barrel 4 abuts against the top end of the elastic stop bar 66, causing the elastic stop bar 66 to move downward. Then, the incineration barrel 4 is pushed so that the outer wall of the incineration barrel 4 is attached to the positioning body 643. At this time, the incineration barrel 4 and the elastic stop bar 66 are misaligned, and the elastic stop bar 66 can move upward and return to its original position. After the elastic stop bar 66 moves upward and resets, it fits against the outer wall of the incinerator 4, thus fixing the position of the incinerator 4. Conversely, when the elastic stop bar 66 is moved downward, the incinerator 4 can be pulled out from the slide plate 64, which makes it easy to place the incinerator 4 on the slide plate 64 and fix its position, and also makes it easy to pull the incinerator 4 out from the slide plate 64.

[0056] As one specific implementation, the front end of the slide plate 64 is integrally provided with an elastic stop rod portion 616. A spring 661 is sleeved on the elastic stop rod 66. The two ends of the spring 661 abut against the elastic stop rod portion 616 and the top end of the elastic stop rod 66 (the top end of the elastic stop rod 66 protrudes outward), respectively, so that the elastic stop rod 66 has an upward tendency to move. The bottom end of the elastic stop rod 66 passes through the elastic stop rod portion 616 and is threadedly connected to a nut (not shown in the figure). The nut abuts against the bottom end face of the elastic stop rod portion 616, which can prevent the elastic stop rod 66 from falling off the elastic stop rod portion 616.

[0057] As one specific implementation, a hook 662 is provided at the top of the elastic stop bar 66. One end of the hook 662 is fully formed into an elastic hook portion 663, which overlaps with the elastic stop bar portion 616 when viewed from above. For example, the hook 662 is made of metal and is U-shaped, making the hook portion 663 elastic. The other end of the hook 662 is fitted onto the top of the elastic stop bar 66, and the spring 661 abuts against the other end of the hook 662. Before the incinerator 4 needs to be pulled out from the slide plate 64, the top of the elastic stop bar 66 and the hook 662 are moved downwards, so that the hook portion 663 undergoes elastic deformation and abuts against the bottom surface of the elastic stop bar portion 616. At this time, the elastic stop bar 66 remains in a lower position and will not obstruct the incinerator 4 from being pulled out from the slide plate 64, making it easier to pull the incinerator 4 out of the slide plate 64. After the incineration barrel 4 is cleaned and placed back on the sliding plate 64, swing the hook part 663 to reset the elastic stop bar 66, so that the incineration barrel 4 can be placed on the sliding plate 64 and fixed in position.

[0058] like Figure 5 , 8 As shown in Figure 20, the incinerator body structure includes an incineration hood 31, a mounting frame 6, and a cylindrical incineration barrel 4.

[0059] The mounting bracket 6 also includes a limiting rod 65, which includes a hinged section 651 and a limiting section 652 perpendicular to the hinged section 651, making the limiting rod 65 overall L-shaped. The hinged section 651 is hinged to the mounting base plate 61, and the limiting section 652 is in contact with the outer wall of the incinerator 4. This ensures accurate alignment between the incinerator 4 and the incinerator hood 31, thereby ensuring the seal between the incinerator 4 and the incinerator hood 31.

[0060] As one specific implementation method, a hinge ear 615 is fixedly provided on the mounting base plate 61, and the hinge segment 651 is embedded in the hinge ear 615 so that the hinge segment 651 is hinged to the mounting base plate 61.

[0061] As one specific implementation, the slide plate 64 is provided with a clamping member 644 that can be raised and lowered relative to the slide plate 64. For example, the clamping member 644 fits through the annular body (not shown in the figure) on the slide plate 64, thereby enabling the slide plate 64 to be raised and lowered. The two ends of the clamping member 644 abut against the bottom end face of the incinerator 4 and the hinge section 651, respectively. The other end of the hinge section 651 (i.e., the other end fixedly connected to the limiting section 652) is provided with a conical section 653. During the process of the slide plate 64 driving the incinerator 4 to move towards the incineration hood 31, the conical section 653 abuts against the clamping member 644, causing the clamping member 644 to move upward and abut against the bottom end face of the incinerator 4, so that the incinerator 4 moves slightly upward and the top end face of the incinerator 4 abuts against the incineration hood 31, which can ensure the sealing between the incinerator 4 and the incineration hood 31. When the ash suction hood 51 needs to absorb the incineration barrel 4, the sliding plate 64 moves the incineration barrel 4 away from the incineration hood 31, and the bottom end of the incineration barrel 4 abuts against the clamping member 644, causing the clamping member 644 to reset.

[0062] As one specific implementation, the slide plate 64 is provided with two support rods 642. The support rods 642 are perpendicular to or parallel to the direction in which the slide plate 64 and the mounting base plate 61 are linearly connected (in embodiments where the support rods 642 are parallel to the direction in which the slide plate 64 and the mounting base plate 61 are linearly connected, this is not shown in the attached drawings). The clamping member 644 is located between the two support rods 642. This can improve the heat insulation effect between the incinerator 4 and the slide plate 64. In the embodiment where the support rods 642 are parallel to the direction in which the slide plate 64 and the mounting base plate 61 are linearly connected, the incinerator 4 can easily move along the support rods 642, making it convenient to place and remove the incinerator 4 (relative to the slide plate 64).

[0063] As one of the specific implementation methods, such as Figure 18 As shown, a limiting seat 654 is provided on the mounting base plate 61, and the limiting seat 654 has a limiting rod groove 655. The limiting segment 652 is inserted into the limiting rod groove 655. For example, the limiting segment 652 is cylindrical, and the inner wall of the limiting rod groove 655 is an arc surface that fits against the limiting segment 652. After the limiting segment 652 is inserted into the limiting rod groove 655, its rotation angle is limited, which can ensure the accurate position of the incinerator 4 and thus ensure the sealing between it and the incinerator hood 31. For example, the cross-section of the hinge segment 651 is semi-circular or other shapes that cause the clamping member 644 to descend after the limiting segment 652 rotates (for example, a semi-circle spliced ​​with half an ellipse, the major axis of which is equal to the diameter of the semi-circle), and the conical segment 653 is frustum-shaped or conical. After the limiting section 652 rotates to roughly fit against the mounting base plate 61, the height of the clamping member 644 decreases, the holding force between the incinerator 4 and the incinerator hood 31 is eliminated, and the incinerator 4 can be easily pulled out from between the sliding plate 64 and the incinerator hood 31.

[0064] As one of the specific implementation methods, such as Figure 18 ,20 As shown, a locking gap 656 is provided between the limiting section 652 and the hinge lug 615 closest to the limiting section 652. When it is necessary to pull the incinerator 4 out from between the slide plate 64 and the incinerator hood 31, the slide plate 64 moves the incinerator 4 slightly away from the incinerator hood 31. The clamping member 644 holds the hinge section 651 and uses friction to move the limiting section 652 out of the limiting rod groove 655. At this time, the limiting section 652 can be rotated until the limiting section 652 is roughly in contact with the mounting base plate 61. This ensures the accurate positioning of the incinerator 4 while facilitating the rotation of the limiting section 652.

[0065] like Figure 4 , 7 As shown, in the improved incineration toilet lid opening mechanism, the incineration sealing member 23 is provided with a sealing member sidewall 235. At least one of the front shafts 231 is an end shaft member 25, which includes a cylindrical section 251 and a threaded section 252. The buffer structure 2 also includes a hexagonal nut 254. The end shaft member 25 passes through the front shaft slide groove 281 and the sealing member sidewall 235 and is threadedly connected to the hexagonal nut 254. The cylindrical section 251 is directly or indirectly embedded in the front shaft slide groove 281. For example, the cylindrical section 251 fits against the inner wall of the front shaft slide groove 281, so that the cylindrical section 251 is directly embedded in the front shaft slide groove 281. Of course, although the rear shaft 232 does not need to be embedded in the through groove 282, the structure of the rear shaft 232 can also be set to the same structure as the front shaft 231 to unify specifications. A gasket 255 is fitted on the end shaft member 25 to prevent the end of the end shaft member 25 (not shown in the figure) from passing through the front shaft slide groove 281, thereby improving reliability. During assembly, it is not necessary to install the sliding wheel onto the release component carrier 28 first. Simply align the incineration sealing component 23 with the front shaft sliding groove 281, and then thread the end shaft component 25 through the front shaft sliding groove 281 and the sealing component side wall 235 to the hexagonal nut 254 to complete the assembly of the end shaft component 25 (i.e. the front shaft 231), which facilitates the assembly of the front shaft 231.

[0066] As one specific implementation, one side of the hexagonal nut 254 is in contact with the top surface of the incineration sealing member 23. During assembly, after aligning the threaded section 252 with the hexagonal nut 254, the end shaft 25 is rotated. The hexagonal nut 254 will not rotate with the end shaft 25 due to the support of the top surface of the incineration sealing member 23, which facilitates the installation of the end shaft 25.

[0067] As one specific implementation, the buffer structure 2 also includes a circular sleeve 253, which fits snugly around the cylindrical section 251, allowing the cylindrical section 251 to indirectly embed into the front shaft groove 281. The circular sleeve 253 can roll relative to the cylindrical section 251, thereby ensuring that the front shaft 231 slides smoothly within the front shaft groove 281 and is less prone to jamming.

[0068] As one specific implementation, a sealing gasket 24 is provided on the bottom end face of the incineration sealing member 23; a mounting top plate 63 is provided below the incineration sealing member 23, and a sealing gasket groove 241 is provided at the top of the mounting top plate 63. The two side walls of the sealing gasket 24 are respectively attached to the two inner walls of the sealing gasket groove 241. The sealing gasket groove 241 can prevent the sealing gasket 24 from deforming when squeezed by the incineration sealing member 23, and can improve the sealing performance of the bottom end face of the incineration sealing member 23.

[0069] As one specific implementation, when the incineration sealing element 23 is fully opened, the two side walls of the sealing gasket 24 are present in the portion where the two inner walls of the sealing gasket groove 241 are in contact. This prevents the sealing gasket 24 from getting stuck when it is completely detached from the sealing gasket groove 241 and then re-enters, thus improving reliability.

[0070] like Figure 19 , 22 As shown, the concealed lid structure of the incineration toilet includes a buffer structure 2, an incineration structure 3, an incineration tank 4, a mounting bracket 6, and an outer cover assembly 7 surrounding the mounting bracket 6. The buffer structure 2, incineration structure 3, and incineration tank 4 are used to incinerate excrement; their specific structures and working principles have been described previously and will not be repeated here. Typically, the outer cover assembly 7 is fixed to the outer periphery of the mounting bracket 6 and surrounds it.

[0071] The mounting frame 6 is a rectangular frame and includes two mounting side plates 62. The buffer structure 2 and the incineration structure 3 are both fixed on the mounting frame 6. The incineration barrel 4 is set inside the mounting frame 6 and can be pulled out from between the two mounting side plates 62.

[0072] The outer cover assembly 7 includes a side cover 71 and an incineration barrel cover 73. The front end of the side cover 71 is provided with a front arc-shaped part 72. The front arc-shaped part 72 has an exposed opening 721 facing the incineration barrel 4. It is easy to understand that when the incineration barrel 4 is viewed directly, the incineration barrel 4 is completely located inside the exposed opening 721, so that the incineration barrel 4 can be pulled out from the exposed opening 721.

[0073] The outer cover assembly 7 also includes two incinerator lid fixing members 74. The incinerator lid fixing member 74 includes a fixing spring 742 and a hemispherical insert 741. The two ends of the fixing spring 742 are fixedly connected to the insert 741 and the mounting side plate 62 respectively. The fixing spring 742 is made of metal.

[0074] The incinerator lid 73 has circular fixing holes 731 on both sides. Embedded parts 741 are inserted into the fixing holes 731, ensuring the lid 73 completely covers the exposed opening 721. It is easy to understand that the arc shape of the incinerator lid 73 is roughly the same as the arc shape of the front curved part 72. The fixing spring 742 is made of materials such as metal springs to ensure sufficient shaping strength and elasticity. To remove the incinerator lid 73, press both embedded parts 741 with your fingers simultaneously to disengage them from the fixing holes 731, thus removing the lid 73. Conversely, the lid 73 can be installed into the exposed opening 721, facilitating the removal and installation of the incinerator lid 73.

[0075] As one specific implementation, both sides of the exposed opening 721 extend inward to form an inner liner 722; the two sides of the incinerator lid 73 abut against the inner liner 722 respectively. This prevents the incinerator lid 73 from completely entering the exposed opening 721 when it is installed.

[0076] As one specific implementation, the incineration barrel lid 73 is elastic, the inner liner 722 is bent inward, and the distance between the two sides of the incineration barrel lid 73 (e.g.) Figure 14 As shown, the distance between the two sides of the incinerator lid 73 refers to the distance perpendicular to the direction of section 2SEC2 (the same applies to the distance between the two sides of the inner liner 722 described later). The distance between the two sides of the inner liner 722 is less than the distance between the two sides of the inner liner 722. The incinerator lid 73 is made of plastic or similar materials and is elastic. When removing the incinerator lid 73, pressing the two inserts 741 simultaneously causes them to detach from the fixing holes 731. Due to its own elasticity, the incinerator lid 73 clamps the inwardly bent inner liner 722, causing the incinerator lid 73 to automatically move away from the inner liner 722. When installing the incinerator lid 73, bringing the incinerator lid 73 close to the inner liner 722 causes the incinerator lid 73 to elastically deform until the inserts 741 are inserted into the fixing holes 731. At this point, the incinerator lid 73 and the inner liner 722 fit tightly together, resulting in a better seal. In other words, the incinerator lid 73 is easy to install and remove while improving sealing.

[0077] As one specific implementation, each of the inner liner 722 is provided with a notch 723, through which the insert 741 is exposed. This avoids the curved inner liner 722 excessively resisting the fixing spring 742 (the fixing spring 742 is fixed on the mounting side plate 62, and the inner liner 722 is curved inward; if the notch 723 is not provided, the inwardly curved end of the inner liner 722 will resist the fixing spring 742, causing the fixing spring 742 to deform excessively) and thus causing the fixing spring 742 to fail, thereby improving reliability.

[0078] As one specific implementation, the fastener spring 742 includes a bent section 743, and the insert 741 is fixed on the bent section 743; the bent section 743 is located within the notch 723. This further prevents the curved inner liner 722 from excessively pressing against the fastener spring 742, thus preventing the fastener spring 742 from failing and improving reliability.

[0079] As one specific implementation, the top and / or bottom of the incinerator lid 73 are provided with shaping ridges 732, and both sides of the shaping ridges 732 are provided with clearance grooves 733. This ensures that the overall shape of the incinerator lid 73 conforms to the design. The clearance grooves 733 are used to avoid the inner liner 722.

[0080] As one specific implementation, the fixing hole 731 is located at the center (i.e., halfway up the height) of the incinerator cover 73, and the two fixing holes 731 are mirror-symmetrical about the incinerator cover 73 itself. No orientation needs to be distinguished when installing the incinerator cover 73, making installation convenient.

[0081] like Figure 10 , 11 As shown in Figure 12, the ash-collecting structure of the incinerator includes a negative pressure device 52, which comprises a negative pressure rotating device 59, a negative pressure outer cover 53, negative pressure blades 54, and a crushing component 55. The negative pressure rotating device 59 is a conventional rotating power device such as an electric motor.

[0082] The negative pressure rotating device 59 is fixed on the negative pressure outer cover 53.

[0083] The negative pressure outer cover 53 is provided with a central hole 533 and a dust discharge pipe 522. The central hole 533 is coaxial with the negative pressure rotating device 59, and the dust discharge pipe 522 is tangential to the rotation direction of the negative pressure rotating device 59. Typically, the central hole 533 extends to form a suction pipe 521, which facilitates the connection between the suction pipe 521 and the dust suction cover 51 via a software. The negative pressure outer cover 53 is divided into an upper cover 531 and a lower cover 532 to facilitate the assembly of the negative pressure device 52.

[0084] The negative pressure blade 54 and the crushing component 55 are sequentially fixed on the rotating output end of the negative pressure rotating device 59. The crushing component 55 is located between the negative pressure blade 54 and the central hole 533 of the outer cover. The negative pressure blade 54 faces the ash discharge pipe 522. In other words, when viewed along the ash discharge pipe 522, there is an overlap between the negative pressure blade 54 and the inner cavity of the ash discharge pipe 522. More specifically, the height of the negative pressure blade 54 is greater than the inner diameter of the ash discharge pipe 522, so that when viewed along the ash discharge pipe 522, the inner cavity of the ash discharge pipe 522 is completely within the height range of the negative pressure blade 54, thus ensuring the efficiency of air and other substances being discharged from the ash discharge pipe 522 when the negative pressure blade 54 rotates.

[0085] The crushing component 55 includes a crushing component top plate 554 and crushing blades 551. The crushing component top plate 554 is located between the negative pressure blades 54 and the crushing blades 551. Gap is provided between the outer end of the crushing blades 551, the outer edge of the crushing component top plate 554 and the inner side wall of the negative pressure outer cover 53.

[0086] The negative pressure rotating device 59 rotates, driving the negative pressure blades 54 and the crushing component 55 to rotate. This causes air to enter through the central hole 533 of the outer cover and exit through the ash discharge pipe 522. This creates negative pressure in the ash-absorbing hood 51, which is connected to the central hole 533 (i.e., the suction pipe 521). The lumpy material inside the incineration chamber 4 is drawn from the central hole 533 into the negative pressure outer cover 53. There, it is blocked by the top plate 554 of the crushing component and then struck by the crushing blades 551, flung outwards. This causes the lumpy material to impact the inner wall of the negative pressure outer cover 53, reducing its particle size and forming ash. The ash is then discharged through the ash discharge pipe 522 along with the air driven by the negative pressure blades 54. As can be seen from the above, the ash-absorbing structure of this incineration toilet can draw in lumpy material formed by the incineration of excrement, preventing it from being crushed into ash, thus ensuring negative pressure and preventing blockage.

[0087] As one specific implementation, the negative pressure blade 54 is a forward-curved blade (the direction pointed to by the outer end of the negative pressure blade 54 is the same as the rotation direction of the negative pressure blade 54), and the pulverizing blade 551 is a backward-curved blade (that is, the direction pointed to by the outer end of the pulverizing blade 551 is opposite to the rotation direction of the negative pressure blade 54), see reference. Figure 11 The grinding component 55's base 552 rotates counterclockwise. It's easy to understand that both the grinding component 55 and the negative pressure blades 54 are fixed to the rotating output shaft of the negative pressure rotating device 59; therefore, the rotation directions of both the negative pressure blades 54 and the grinding blades 551 are counterclockwise. Figure 11 The rotation direction shown is counterclockwise, while the outer end of the pulverizing blade 551 faces clockwise, opposite to its rotation direction. The pulverizing blade 551 is a backward-curved blade. Based on this, it is easy to understand that the rotation direction of the negative pressure blade 54 is also counterclockwise. Figure 11 The display shows a counter-clockwise rotation, and its outer end faces counter-clockwise; the negative pressure blade 54 is a forward-curved blade. When the negative pressure rotating device 59 drives the negative pressure blade 54 and the pulverizing element 55 to rotate, the negative pressure blade 54 generates a large air pressure, which can ensure that there is a large negative pressure in the suction pipe 521. After the lumps adhere to the pulverizing blade 551, they are thrown out by the pulverizing blade 551 at a large speed, which can improve the pulverizing effect (so that the lumps are turned into ash with smaller particle size) and prevent the lumps from adhering to the pulverizing blade 551.

[0088] As one specific implementation method, the number of crushing blades 551 is less than the number of negative pressure blades 54.

[0089] As one specific implementation, the pulverizer 55 also includes a pulverizer chassis 552 with a central hole 553, and the pulverizing blades 551 are located between the pulverizer chassis 552 and the pulverizer top chassis 554. If occasionally a large block appears, it cannot pass between the pulverizer chassis 552 and the pulverizer top chassis 554 and stays at the central hole 553, causing the negative pressure device 52 to become blocked. After removing the hose connected to the suction pipe 521 (the other end of the hose is connected to the dust suction cover 51), the large block will fall off without causing internal blockage of the negative pressure cover 53, thereby improving the usability of the negative pressure device 52.

[0090] As one specific implementation method, the inner diameter of the outer cover center hole 533 is smaller than the inner diameter of the chassis center hole 553, and the inner ends of the crushing blades 551 are all located on the circumference of the chassis center hole 553.

[0091] like Figure 16 , 17 As shown, the ash water tank structure of the incineration toilet includes an ash water tank 9. The ash water tank 9 includes a connecting hose 911 for receiving lumps or ash formed from incinerated excrement. An atmospheric connection pipe 912 is located at the top of the ash water tank 91, and the atmospheric connection pipe 912 is surrounded by a filter element 92. This structure prevents excessive pressure and rupture of the ash water tank 91 caused by the continuous flow of gas containing lumps or ash into the ash water tank 91, while also reducing odorous substances overflowing from the atmospheric connection pipe 912.

[0092] As one of the specific implementation methods, such as Figure 17 As shown, the atmospheric connecting pipe 912 is a rigid circular tube with an annular protrusion extending into the bottom end (not shown in the attached figure). The filter element 92 includes a rigid bottom ring 921 and a rigid top cover 923. A filter body 922 is disposed between the bottom ring 921 and the rigid top cover 923. The annular protrusion fits snugly onto the atmospheric connecting pipe 912, facilitating the disassembly and installation of the filter element 92. The filter body 922 is made of filter paper to reduce odorous substances escaping from the atmospheric connecting pipe 912.

[0093] As one specific implementation, the outer diameter of the rigid top cover 923 is smaller than the outer diameter of the bottom ring 921. A grey water discharge pipe 919 is provided on the bottom surface of the grey water tank 91; a discharge valve 918 is provided on the grey water discharge pipe 919. The discharge valve 918 is typically a manually operated ball valve. Opening the discharge valve 918 allows for convenient discharge of grey water from the grey water tank 91, such as into a toilet or sewer.
