[0056] Figure 1 A perspective view of a toilet according to an embodiment of the present invention is shown schematically; Figure 2 The diagram schematically shows a first-view perspective view of the seat ring and toilet body according to an embodiment of the present invention.

[0057] An embodiment of this utility model provides a commode for use on a nursing bed, such as... Figure 1 and Figure 2As shown, the device includes a toilet body 1, a seat ring 2, and an outdoor exhaust fan 3. The toilet body 1 is located below the toilet opening of the nursing bed; the seat ring 2 is located on the toilet body 1, and an exhaust channel 21 is formed inside the seat ring 2. The exhaust channel 21 is provided with multiple exhaust holes 22, which are used to guide the gas inside the toilet body 1 to the exhaust channel 21; the outdoor exhaust fan 3 is connected to the exhaust channel 21 to discharge the gas in the exhaust channel 21.

[0058] According to the above configuration, by setting an exhaust channel 21 on the seat ring 2 that communicates with the toilet body 1, and connecting the exhaust channel 21 to the outdoor exhaust fan 3, the problem of odors left after long-term bedridden elderly people use the toilet is effectively solved. This not only ensures fresh indoor air and improves the hygiene of the living environment, but also greatly reduces the workload of caregivers and improves the quality of life and dignity of the elderly. In addition, the arrangement of multiple exhaust holes 22 optimizes exhaust efficiency, allowing for more rapid and thorough gas discharge from the toilet body 1, achieving good ventilation of the toilet body 1, and ensuring a clean and comfortable living environment.

[0059] In one illustrative embodiment, such as Figure 1 and Figure 2 As shown, the outdoor exhaust fan 3 is connected to the exhaust port 211 located on the exhaust channel 21 via the outdoor unit pipe 31.

[0060] According to the above setup, the outdoor exhaust fan 3 is installed outdoors using the outdoor unit pipe 31. After urination or defecation, the odorous gas inside the toilet body 1 is exhausted to the outside, ensuring the cleanliness of the indoor environment.

[0061] Figure 3 A schematic cross-sectional view of the toilet seat and toilet body according to an embodiment of the present invention is shown. Figure 4 for Figure 3 An enlarged view of the seat ring portion in the sectional view shown; Figure 5 A perspective view of the seat ring according to an embodiment of the present invention is shown schematically; Figure 6 A bottom view of the seat ring according to an embodiment of the present invention is shown schematically.

[0062] In one illustrative embodiment, such as Figures 3 to 6 As shown, the exhaust channel 21 is configured as an annular channel extending circumferentially in the seat ring 2; a plurality of exhaust holes 22 are provided on the wall surface of the exhaust channel 21 facing the toilet body 1, and are evenly spaced in the extending direction of the exhaust channel 21.

[0063] Based on the above configuration, by designing the exhaust channel 21 as a ring-shaped channel extending circumferentially from the seat ring 2, and evenly arranging multiple exhaust holes 22 on its inner wall facing the toilet body 1, the exhaust efficiency is effectively improved. This ensures that odors inside the toilet body 1 can be quickly and evenly expelled, thereby significantly improving the hygiene and comfort of the indoor environment. Furthermore, the evenly distributed exhaust hole design helps reduce exhaust dead zones, ensuring continuous airflow inside the toilet and further enhancing the user experience during use.

[0064] In one illustrative embodiment, such as Figure 1 and Figure 2 As shown, it also includes a sealing cover 4, which has an end that engages with the seat ring 2 to seal the toilet body 1 in a first state, and a second state that is away from the seat ring 2.

[0065] According to the above-described configuration, the sealing cover 4 effectively prevents odor leakage during toilet use, maintaining fresh indoor air. In the first state, the tight fit of the sealing cover 4 ensures the sealing of the toilet body 1, while in the second state, it facilitates user use and cleaning of the toilet, improving operational convenience and hygiene.

[0066] Figure 7 A schematic perspective view of the toilet body and lifting device according to an embodiment of the present invention is shown. Figure 8 A perspective view of a lifting device according to an embodiment of the present invention is shown schematically.

[0067] In one illustrative embodiment, such as Figure 7 and Figure 8 As shown, it also includes a lifting device 5, which is adapted to drive the toilet body 1 to move between a first position in which the seat ring 2 is flush with the toilet opening of the nursing bed and a second position away from the toilet opening of the nursing bed.

[0068] Based on the above configuration, the lifting device 5 greatly enhances the adaptability and convenience of the toilet. Users can adjust the position of the toilet body 1 according to their needs, allowing the seat ring 2 to precisely align with the toilet opening of the nursing bed, facilitating user operation. Furthermore, when the toilet body 1 is in the second position, it provides more space and convenience for cleaning and maintenance. Additionally, the sealing cover 4 can be fastened to the seat ring 2 to seal the interior of the toilet body 1, preventing the leakage of odorous gases.

[0069] In one illustrative embodiment, such as Figure 8As shown, the lifting device 5 includes a moving platform 51, a fixed platform 52, and a scissor lift frame 53. The moving platform 51 is suitable for mounting the toilet body 1; the fixed platform 52 is mounted on the bed frame of the nursing bed; the scissor lift frame 53 is installed between the moving platform 51 and the fixed platform 52, and is suitable for changing the height in the vertical direction to drive the moving platform 51 to move the toilet body 1 between a first position and a second position.

[0070] In detail, the scissor lift frame 53 includes two symmetrically arranged scissor frames. Each scissor frame includes a first beam 531 and a second beam 532 that are hinged together. The first end of the first beam 531 is rotatably mounted on the fixed platform 52, and the second end is slidably mounted on the slide rail 511 on the moving platform 51. The first end of the second beam 532 is rotatably mounted on the moving platform 51, and the second end is slidably mounted on the slide rail 521 on the fixed platform 52.

[0071] According to embodiments of this disclosure, pulleys are respectively installed at the second end of the first beam 531 and the second end of the second beam 532, which are respectively suitable for sliding cooperation with the slide rail 511 and the slide rail 521.

[0072] In one illustrative embodiment, such as Figure 8 As shown, the first beam 531 and the second beam 532 of the two sets of scissor lifts are fixedly connected by crossbeams. A first drive unit 533 is provided between the two crossbeams, which is suitable for driving the two crossbeams to move, so as to change the included angle between the first beam 531 and the second beam 532, thereby changing the distance between the moving platform 51 and the fixed platform 52, and driving the toilet body 1 to move between the first position and the second position.

[0073] In one illustrative embodiment, slide rails 511 and 521 are arranged in parallel and configured to extend in the horizontal direction.

[0074] In one illustrative embodiment, the first drive unit 533 includes an electric actuator.

[0075] According to the above configuration, the lifting device 5 not only ensures that the toilet body 1 can move smoothly and accurately between the first and second positions, allowing the toilet to switch between use and storage, but also makes the lifting process more effortless and easier to control through the drive of the electric push rod. This design improves the automation level of the nursing bed, reduces the workload of caregivers, and provides a more humane, safe, and reliable user experience for elderly people who are bedridden for a long time, greatly enhancing the practicality and functionality of the overall nursing facilities.

[0076] In one illustrative embodiment, due to the limited height of the nursing bed, the lifting range of the toilet body 1 is also limited, and the lifting stroke is a precise fixed distance. Therefore, the electric actuator can be selected with a fixed stroke according to the required distance. For example, when the electric actuator is fully extended, it can raise the lifting device 5 to the highest position, i.e., the toilet body 1 is in the first position; when fully retracted, it can lower the lifting device 5 to the lowest position, i.e., the toilet body 1 is in the second position. Thus, by controlling these two extreme positions, accurate lifting of the toilet body 1 can be ensured without the need for an additional dedicated height adjustment device.

[0077] Figure 9 A schematic perspective view of the installation of the sealing cover and the moving device according to an embodiment of the present invention is shown.

[0078] In one illustrative embodiment, such as Figure 9 As shown, it also includes a moving device 6, which is adapted to drive the sealing cover 4 to move in the horizontal direction to switch between a first state and a second state.

[0079] According to the above-described configuration, the movable device 6 makes the operation of the sealing cover 4 more convenient and efficient. Users or caregivers can easily control the position of the sealing cover 4, ensuring the toilet's sealing and cleanliness during use. This improves the toilet's ease of use and effectively reduces odor leakage, maintaining a hygienic indoor environment.

[0080] In one illustrative embodiment, such as Figure 9 As shown, the moving device 6 includes a guide rail 61, a lifting unit 62, and a second drive unit 63. The guide rail 61 is mounted on the bed frame of the nursing bed; the lifting unit 62 is movably mounted on the guide rail 61, and the lifting unit 62 is connected to the sealing cover 4 and is configured to extend and retract in the vertical direction, so that the sealing cover 4 moves vertically with the toilet body 1 in the first state; the second drive unit 63 is adapted to drive the lifting unit 62 to move along the guide rail 61 to drive the sealing cover 4 to switch between the first state and the second state.

[0081] In detail, the lifting unit 62 includes a liftable telescopic rod, the height of which can be freely adjusted as the sealing cover 4 is raised or lowered, and the telescopic rod is movably mounted on the guide rail 61 via a slider.

[0082] In one illustrative embodiment, the second drive unit 63 includes an electric actuator.

[0083] According to an embodiment of this disclosure, when the toilet body 1 is in the second position, the second drive unit 63 drives the lifting unit 62 to move the sealing cover 4 horizontally. At this time, the telescopic rod is in its shortest position, allowing the sealing cover 4 to just engage with the seat ring 2. When the sealing cover 4 is in the engaged first state, the lifting device 5 drives the toilet body 1 to rise, causing the sealing cover 4 to rise as well, stopping when it is flush with the bed board of the nursing bed. At this time, the sealing cover 4 can seal the toilet opening, and the telescopic rod extends with the sealing cover 4 to its longest position. When the user needs to use the toilet, the toilet body 1 needs to be lowered. After the second drive unit 63 drives the lifting unit to move horizontally to bring the sealing cover to the second state, the toilet body 1 moves back to the first position, and the user can then use the toilet.

[0084] In one illustrative embodiment, such as Figure 1 As shown, it also includes an electronic control unit 7, which is installed on the toilet body 1 and communicates with the lifting device 5, the moving device 6, and the outdoor exhaust fan 3. It is suitable for the user to control the toilet during use.

[0085] In one illustrative embodiment, a positioning unit is also included, which is communicatively connected to the outdoor exhaust fan 3 and is suitable for obtaining the position of the sealing cover 4 relative to the seat ring 2; the outdoor exhaust fan 3 is in a first speed mode when the sealing cover 4 is in a first state and in a second speed mode when the sealing cover 4 is in a second state; wherein, the speed of the outdoor exhaust fan 3 in the first speed mode is less than the speed of the outdoor exhaust fan 3 in the second speed mode.

[0086] In detail, the positioning unit includes a limit switch, which is set on the electric push rod of the second drive unit. When the push rod moves to the preset position, it can trigger the limit switch to obtain the position of the driven sealing cover 4. The outdoor exhaust fan 3 then switches between the first speed mode and the second speed mode in response to its position.

[0087] In an alternative embodiment, the positioning unit includes a position sensor for real-time monitoring of the position of the sealing cap 4.

[0088] In detail, the outdoor exhaust fan is designed to operate 24 hours a day without interruption, automatically adjusting its operating speed according to usage (i.e., the state of the sealing cover 4). Specifically, when the sealing cover 4 is in the second state, and the user is using the toilet for urination or defecation, the outdoor exhaust fan 3 enters high-speed operation mode. In this mode, the fan operates at higher power, quickly and forcefully extracting stale air from the toilet body 1 to reduce odors as quickly as possible. Once the user has finished using the toilet and closed the sealing cover 4, the sealing cover 4 returns to the first state, and the outdoor exhaust fan 3 automatically switches to low-speed mode. In this mode, the fan continues to operate at lower power, continuously and slowly expelling gas from the toilet body 1 and some surrounding air from the room, maintaining a consistently fresh indoor air environment.

[0089] In one illustrative embodiment, a drain outlet 11 is formed on the toilet body 1, and the drain outlet 11 is connected to a U-bend 8.

[0090] In one illustrative embodiment, the toilet body 1 is also provided with a plurality of mounting posts 12, which are suitable for connecting bolts, and the toilet body 1 is fixed to the lifting device 5 by bolt connection.

[0091] According to the above-mentioned setup, the waste is discharged smoothly and the foul odor from the sewer is prevented from flowing back into the toilet body 1, thereby improving the hygiene and comfort of the user environment.

[0092] An embodiment of this utility model also provides a nursing bed, including a bed frame and a bed board, with a toilet seat provided on the bed board and the aforementioned toilet installed below the toilet seat.
