[0002] CN221654150U discloses an incineration toilet, which includes at least a buffer structure and an incineration structure; the buffer structure includes a release member and a buffer member, the buffer member being provided with a buffer groove and a release port; the incineration structure includes an incineration sealing member and an incineration barrel with a top opening, the top of the incineration barrel being a receiving part; when viewed from above, the release port and the top opening of the incineration barrel overlap; the release member and the buffer member are hinged and completely cover the release port; the incineration sealing member is hinged to the incineration barrel and completely covers the top opening of the incineration barrel; the incineration barrel also includes an incineration part located below the receiving part, the incineration part being provided with a heating element; both the release member and the incineration sealing member have rotational power.
[0003] The incineration toilet disclosed in CN221654150U has a flip-top opening on its lid that connects to the outside without any protection, allowing water to enter the incineration toilet during flushing. Since the incineration device typically operates at high power, this water entering the incineration toilet could potentially cause short circuits, indicating room for improvement in safety.
[0004] Furthermore, CN221654150U discloses an incineration toilet that uses a magnetic sensor to identify the open and closed state of the movable lid. However, the reliability of identifying the open and closed state of the movable lid using a magnetic sensor is affected by factors such as circuit setting parameters, changes in the state of the permanent magnet, and water entering the incineration toilet, resulting in low reliability. When using microswitches or other alternatives to magnetic switches, factors such as waterproofing and reliability must also be considered. Utility Model Content
[0005] One objective of this invention is to solve or alleviate the aforementioned technical problems.
[0006] The present invention employs a sealing structure for the top cover of an incineration toilet, comprising a top cover and a movable cover; the incineration toilet includes an incineration container for incinerating excrement; the top cover is positioned above the incineration container and has a through opening that communicates with the incineration container; it also includes a flipping component and a contact sensor with a triggered end; the contact sensor is electrically connected to the incineration container; the flipping component includes a flipping frame and a mounting frame; the flipping frame includes a hinge end, an arc segment, and a cover connecting end; the hinge end has a section with a hinge shaft hinged to the mounting frame; the arc segment, when viewed from the side, is a fan-shaped ring centered on the axis of the hinge shaft; the mounting frame is fixedly connected to the inner wall of the top cover; the top cover has an exposed opening; the arc segment passes through the exposed opening, and the cover connecting end is fixedly connected to the movable cover; the contact sensor is fixed on the mounting frame and located behind the hinge end; the triggered end is located on the rotation path of the hinge end; the hinge end is vertical when the movable cover is closed.
[0007] The effect achieved by this invention is to improve the electrical safety of contact sensors while ensuring their reliability.
[0008] A further technical solution involves extending the mounting bracket downwards on both sides to form the mounting bracket sidewalls, making the overall cross-section of the mounting bracket U-shaped.
[0009] It can prevent condensation and other substances from coming into contact with the contact sensor, thereby improving electrical safety.
[0010] A further technical solution involves a contact sensor that is a microswitch with a triggered end. The contact sensor is completely higher than the bottom of the hinge end, and the triggered end is positioned downwards.
[0011] Under the premise of ensuring the reliability of contact sensors,
[0012] A further technical solution involves the mounting bracket extending downwards to form an extension body, which is located between the side walls of the two mounting brackets when viewed from above; the contact sensor is fixedly connected to the extension body, and the side wall of the contact sensor is in contact with the extension body.
[0013] It facilitates the assembly of contact sensors.
[0014] A further technical solution involves providing a limiting wall between the two mounting bracket sidewalls, with the limiting wall abutting against the hinged end.
[0015] It can prevent the hinged end from excessively pressing against the triggered end, which could damage the contact sensor.
[0016] A further technical solution is to provide an elastic sealing ring on the bottom surface of the movable cover. When the movable cover is closed, the through opening is completely located inside the sealing ring. When the sealing ring abuts against the top cover, the hinge end contacts the triggered end.
[0017] It can improve the reliability of contact sensors.
[0018] Further technical solutions also include a flexible sealing element, which is fixedly connected to the top cover; the sealing element includes a sealing body that covers the exposed opening; the sealing body has a strip-shaped hole, and an arc segment fits through the strip-shaped hole.
[0019] This can further improve the electrical safety of contact sensors. Attached Figure Description

Detailed Implementation
[0033] The specific embodiments of this utility model will now be described with reference to the accompanying drawings.
[0034] As a specific embodiment, the top cover sealing structure of the incineration toilet of this utility model includes a top cover 1 and a movable cover 2.
[0035] The incineration toilet includes an incineration container (not shown in the attached drawing, the incineration container is existing technology, which uses electric heating, flame incineration or other methods to incinerate the excrement, thereby removing moisture and deodorizing the excrement).
[0036] The top cover 1 is used to be placed above the incineration container and is provided with a through opening 19 that can communicate with the incineration container.
[0037] The sealing structure of the top cover of the incineration toilet according to an embodiment of the present invention also includes a flipping component 3 and a sealing component 4.
[0038] The flipping component 3 includes a flipping frame 31 and a mounting frame 32. The flipping frame 31 includes a hinge end 311, an arc segment 313 and a cover connecting end 319. The hinge end 311 has a section with a hinge shaft 312 that is hinged to the mounting frame 32. When viewed from the side, the arc segment 313 is a fan-shaped ring with the axis of the hinge shaft 312 as the center (a part of a ring cut off by a fan shape).
[0039] Mounting bracket 32 is fixedly connected to the inner wall of top cover 1, and cover connection end 319 is fixedly connected to movable cover 2.
[0040] The top cover 1 is provided with an exposed opening 14, and the sealing element 4 is fixedly connected to the top cover 1.
[0041] The sealing element 4 includes a sealing body 41 that covers the exposed opening 14; the sealing body 41 has a strip-shaped hole 411, and the arc segment 313 fits through the strip-shaped hole 411. In the case of flushing or incinerating the toilet, it can prevent water from entering the top cover 1 from the exposed opening 14, thereby improving electrical safety.
[0042] As one specific implementation method, the seal 4 is made of rubber or the like and is elastic.
[0043] As one specific implementation, the sealing body 41 protrudes upward to form a sealing protrusion 412; a strip-shaped hole 411 is provided on the sealing protrusion 412, and the thickness of the sealing protrusion 412 is less than the thickness of the sealing body 41. When the movable cover 2 is opened or closed, the sealing protrusion 412 is more likely to deform, so that the sealing protrusion 412 forms an inclination angle as the arc segment 313 moves. Even if the strip-shaped hole 411 is in close contact with the arc segment 313, it can ensure that the arc segment 313 moves smoothly within the strip-shaped hole 411. In other words, while ensuring sealing, it can also ensure that the arc segment 313 moves smoothly within the strip-shaped hole 411.
[0044] As one specific implementation, the rear end of the top cover 1 extends upward to form an inclined rear end boss 11. The exposed opening 14 has a portion located on the sealing body 41 and a portion located on the rear end boss 11. The edge of the exposed opening 14 extends upward to form a U-shaped exposed edge 141 when viewed from above. The sealing body 41 extends downward to form an outer casing 42 and an inner liner 43 (it is easy to understand that the outer casing 42 and the inner liner 43 are also U-shaped as a whole). The exposed edge 141 is embedded between the outer casing 42 and the inner liner 43, so that the seal 4 is fixedly connected to the top cover 1. When installing the seal 4, the seal 4 is moved from the outside of the top cover 1 toward the exposed opening 14, so that the exposed edge 141 is embedded between the outer casing 42 and the inner liner 43. There is no need to use screws or other fixation, which makes it easy to install the seal 4 onto the top cover 1.
[0045] As one specific implementation, the ends (one or both ends) of the inner liner 43 extend outward to form a retaining body 431; the retaining body 431 fits against the inner wall of the rear end boss 11, and the arc segment 313 passes through the U-shaped internal space of the inner liner 43. When installing the seal 4, the retaining body 431 is pressed inward and the exposed edge 141 is embedded between the outer casing 42 and the inner liner 43. The retaining body 431 then enters the rear end boss 11 and resets, abutting against the inner wall of the rear end boss 11. This ensures the installation strength between the seal 4 and the top cover 1, while also facilitating the installation of the seal 4 onto the top cover 1.
[0046] As one specific implementation, the rear end of the sealing body 41 extends upward to form an embedding portion 415, which is embedded into the portion of the exposed opening 14 located on the rear end boss 11. When installing the seal 4, the supporting body 431 is pressed inward and the exposed edge 141 is embedded between the outer casing 42 and the inner liner 43. At the same time, the embedding portion 415 is embedded into the portion of the exposed opening 14 located on the rear end boss 11, thereby restricting the vertical movement of the seal 4. This ensures the installation strength and sealing performance between the seal 4 and the top cover 1, while also facilitating the installation of the seal 4 onto the top cover 1.
[0047] As one specific implementation, the insert 415 is provided with a fitting body 413, which abuts against the rear end face 21 and the rear end boss 11. In other words, the rear end face 21 and the rear end boss 11 clamp the fitting body 413. After the movable cover 2 is closed, the rear end face 21 and the rear end boss 11 directly or indirectly clamp the fitting body 413, which can improve the sealing performance of the seal 4.
[0048] As one specific implementation, the outer surface of the fitting body 413 is provided with protruding ribs 414. This can further improve the sealing performance of the seal 4.
[0049] The sealing structure of the incineration toilet lid in this embodiment of the present invention also includes a flipping component 3 and a contact sensor 5 with a triggered end 51.
[0050] The contact sensor 5 is electrically connected to the incineration container. For example, the contact sensor 5 is electrically connected to the electric heating tube, igniter, etc. of the incineration container to limit the activation of the electric heating tube, igniter, etc. of the incineration container according to the open and closed state of the movable cover 2. In addition, the contact sensor 5 can also be used as a reliable electrical signal input device to input signals to the circuit board and other electronic control devices (not shown in the figure) to determine the open and closed state of the movable cover 2.
[0051] The flipping component 3 includes a flipping frame 31 and a mounting frame 32. The flipping frame 31 includes a hinge end 311, an arc segment 313 and a cover connecting end 319. The hinge end 311 has a section with a hinge shaft 312 that is hinged to the mounting frame 32. When viewed from the side, the arc segment 313 is a fan-shaped ring with the axis of the hinge shaft 312 as its center.
[0052] Mounting bracket 32 is fixedly connected to the inner wall of top cover 1. Top cover 1 is provided with an exposed opening 14. Arc segment 313 passes through exposed opening 14 and cover connecting end 319 is fixedly connected to movable cover 2.
[0053] The contact sensor 5 is fixed on the mounting bracket 32 and located behind the hinge end 311.
[0054] The triggered end 51 is located on the rotation path of the hinge end 311, and the hinge end 311 is vertical when the movable cover 2 is closed. In situations such as flushing or incinerating toilets, a small amount of water will flow along the arc segment 313 to the junction of the arc segment 313 and the hinge end 311 (i.e., the corner of the arc segment 313 and the hinge end 311) due to its own weight, without contacting the contact sensor 5. This improves the electrical safety of the contact sensor 5 while ensuring its reliability.
[0055] As one specific implementation, the mounting bracket 32 extends downwards on both sides to form mounting bracket sidewalls 321, making the overall cross-section of the mounting bracket 32 U-shaped. This increases the strength of the mounting bracket 32 while preventing condensation and other substances from contacting the contact sensor 5, thus improving electrical safety.
[0056] As one specific implementation, the contact sensor 5 is a microswitch with a triggered end 51. The contact sensor 5 is completely higher than the bottom end of the hinge end 311, and the triggered end 51 is set downwards (i.e., the spring opening of the triggered end 51 faces downwards). Compared with Hall effect sensors, microswitches have higher reliability. While ensuring the reliability of the contact sensor 5,
[0057] As one specific implementation, the mounting bracket 32 extends downward to form an extension body 322, which, when viewed from above, is located between the two mounting bracket sidewalls 321. The contact sensor 5 is fixedly connected to the extension body 322, for example, by screwing a screw through the contact sensor 5 into the extension body 322. The sidewall of the contact sensor 5 is in contact with the extension body 322. During assembly, the screw is first screwed through the mounting bracket 32 into the top cover 1, and then the screw is screwed through the contact sensor 5 into the extension body 322, which facilitates the assembly of the contact sensor 5.
[0058] As one specific implementation, a limiting wall 323 is provided between the two mounting bracket sidewalls 321, and the limiting wall 323 abuts against the hinge end 311. This can prevent the hinge end 311 from excessively pressing against the triggered end 51 (for example, when a person sits on the movable cover 2), thereby causing damage to the contact sensor 5.
[0059] As one specific implementation, the bottom surface of the movable cover 2 is provided with an elastic sealing ring 29. When the movable cover 2 is closed, the through-hole 19 is completely located within the sealing ring 29. When the sealing ring 29 abuts against the top cover 1 (or against the through-hole protrusion 191 provided around the through-hole 19), the hinge end 311 contacts the triggered end 51. When the movable cover 2 is closed, it can reduce or conversely reduce the airflow between the through-hole 19 and the outside, thus achieving odor prevention. When the movable cover 2 is closed, the sealing ring 29 acts as a buffer at the end of the movable cover 2 that falls freely, preventing the triggered end 51 from being damaged by strong pressure. In addition, when a person sits on the movable cover 2, the sealing ring 29 also acts as a buffer, preventing the triggered end 51 from being damaged by strong pressure. In other words, while achieving odor prevention, it can also improve the reliability of the contact sensor 5.
[0060] As one specific implementation, it also includes a resilient sealing element 4, which is fixedly connected to the top cover 1; the sealing element 4 includes a sealing body 41 that covers the exposed opening 14; the sealing body 41 has a strip-shaped hole 411, and an arc segment 313 fits through the strip-shaped hole 411. This can further improve the electrical safety of the contact sensor 5.

[0062] In this invention, terms such as "a" or "an" are used to indicate not a limitation on the quantity, but rather to indicate the existence of at least one of the mentioned objects.
[0063] In this utility model, terms indicating direction or location such as top, bottom, side, longitudinal, transverse, middle, center, outside, inside, horizontal, vertical, left, right, above, and below are used to indicate relative positions rather than absolute positions.
[0064] Terms used in this invention, such as "approximately," "generally," "approximately," and "similar," are limiting terms used to indicate features that are present but allow for certain deviations. The amount of deviation allowed may vary depending on the specific context; for example, regarding dimensional deviations, the specific context may include, but is not limited to, relevant standards for dimensional tolerances.
