Description

Technical Field

[0001] This invention relates to the field of squat toilet assistive devices, specifically to a multifunctional squat toilet for the elderly. Background Technology

[0002] Common joint diseases in the elderly include arthritis, osteoarthritis, and rheumatoid arthritis. These conditions can lead to joint inflammation, degenerative changes in the joints, and joint effusion, thus affecting normal joint movement. When squatting, due to limited joint mobility, the elderly may experience pain or weakness, making it difficult to complete the squatting action. Therefore, the elderly often use squat toilets when defecating.

[0003] For example, Chinese patent application number 202020608681.0 discloses a squat toilet that prevents falls, including a squat toilet body, a sewage outlet in the middle of the squat toilet body, foot pedals on both sides of the squat toilet body, and guardrails for users to hold on to on both foot pedals; multiple first strip-shaped protrusions are provided on the foot pedals, and first drainage holes are provided between the multiple first strip-shaped protrusions, and the first drainage holes are connected to the sewage outlet.

[0004] Most squat toilets in the current technology have a simple structure, which is not convenient for assisting the elderly in squatting and standing when using the toilet, reducing the comfort and safety of the elderly when using the toilet. In addition, the height of the squat toilet cannot be adjusted, making it inconvenient for different elderly people to use, thus reducing the practicality of the device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention proposes a multifunctional squat toilet for the elderly, which assists the elderly in squatting and standing when using the toilet, improving their comfort and safety. The height of the squat toilet is adjustable to accommodate different elderly individuals, thus enhancing the device's practicality.

[0006] A multi-functional squat toilet for the elderly, comprising:

[0007] The base has legs at both ends, and two sets of guide columns are vertically arranged at the top of the base. The tops of the two sets of guide columns are connected to a backrest.

[0008] A guide seat is slidably mounted on two sets of guide columns in a vertical direction; a seat cushion is rotatably mounted on the guide seat, the seat cushion is located between the two sets of support legs, and the seat cushion has a through-hole for defecation along its thickness direction.

[0009] A drive assembly, disposed on the backrest and connected to the guide seat, is used to drive the guide seat to move up and down; and

[0010] A transmission assembly connects the base, the guide seat, and the seat cushion. When the guide seat moves downward, it can drive the seat cushion to rotate clockwise via the transmission assembly. This ensures that the seat cushion is horizontal when the guide seat moves downward to the seat height, and keeps the seat cushion horizontal when the guide seat is below the seat height. When the guide seat moves upward, it can drive the seat cushion to move upward while maintaining a horizontal state via the transmission assembly, and drives the seat cushion to rotate counterclockwise when the guide seat is above the seat height.

[0011] The beneficial effects of the above-mentioned multifunctional squat toilet for the elderly are:

[0012] 1. By placing the buttocks and back against the seat cushion and backrest respectively, the control drive component moves the guide seat downwards. The downward movement of the guide seat causes the seat cushion to move downwards and rotate clockwise through the transmission component. When the guide seat moves downwards to the sitting height and the seat cushion is horizontal, the seat cushion can support the elderly person from a standing to a sitting position. As the drive component continues to move the guide seat downwards below the sitting height, the guide seat moves the seat cushion downwards and maintains the seat cushion horizontally through the transmission component. The horizontal downward movement of the seat cushion can support the elderly person from a sitting to a squatting position. Conversely, the control drive component moves the guide seat upwards, causing the guide seat to move horizontally upwards. When the guide seat moves upwards to the sitting height, the seat cushion can support the elderly person from a squatting to a sitting position. As the drive component continues to move the guide seat upwards above the sitting height, the guide seat moves the seat cushion upwards and rotates counterclockwise through the transmission component. The upward movement and counterclockwise rotation of the seat cushion can support the elderly person from a sitting to a standing position. This facilitates the elderly person's squatting and standing when using the toilet, improving the comfort and safety of the elderly person when using the toilet.

[0013] 2. Simply control the guide seat to move down or up to support the elderly in changing postures from standing to sitting to squatting or from squatting to sitting and back to standing. The operation is simple and convenient, further improving the comfort of the elderly when squatting and standing.

[0014] 3. When the guide seat is lower than the sitting height, the height of the seat can be adjusted by moving the guide seat up or down through the drive component. This allows for easy adjustment of the squat toilet height according to needs, making it easier for different elderly people to use and improving the practicality of the device.

[0015] In one embodiment, the driving assembly includes a first screw and a motor. The first screw is rotatably mounted on the backrest and parallel to the guide post. The bottom end of the first screw is threadedly connected to the guide seat. The motor is mounted on the backrest, and its output end is coaxially connected to the first screw via a coupling. By controlling the motor to drive the first screw to rotate, the rotation of the first screw engages with the threaded engagement of the guide seat, driving the guide seat to move downwards. By controlling the motor to drive the first screw to rotate in the opposite direction, the reverse rotation of the first screw engages with the threaded engagement of the guide seat, driving the guide seat to move upwards. This facilitates the up-and-down movement of the guide seat. Furthermore, by controlling the motor to stop driving the first screw to rotate, the first screw stops rotating and forms a threaded self-locking mechanism with the guide seat, securing the guide seat easily.

[0016] In one embodiment, the transmission assembly includes a worm, a worm wheel, and a guide shaft; the worm is rotatably mounted on the guide seat, a rotating shaft is horizontally mounted at one end of the cushion, the rotating shaft is rotatably mounted on the guide seat, the worm wheel is coaxially mounted at one end of the rotating shaft and meshes with the worm, the guide shaft is vertically mounted on the base, the worm is coaxially sleeved on the guide shaft, a helical guide groove is formed on the upper circumference of the guide shaft, a limiting guide groove is formed on the lower circumference of the guide shaft in a vertical direction, the bottom end of the helical guide groove communicates with the top end of the limiting guide groove, a guide hemisphere is provided inside the worm, and the guide hemisphere is slidably mounted in the helical guide groove and the limiting guide groove. When the guide seat moves downwards, it drives the seat cushion, worm gear, and worm wheel to move downwards. The downward movement of the worm gear causes the guide hemisphere to slide along the spiral guide groove. The sliding of the guide hemisphere along the spiral guide groove drives the worm gear to rotate. The rotation of the worm gear meshes with the worm wheel, driving the worm wheel to rotate clockwise. The clockwise rotation of the worm wheel drives the seat cushion to rotate clockwise. When the guide seat moves downwards to the seat height, the seat cushion is horizontal, and the guide hemisphere is located at the connection between the spiral guide groove and the limiting guide groove. When the guide seat continues to move downwards, it drives the seat cushion to move downwards, and the guide hemisphere slides downwards along the limiting guide groove. At this point, the worm gear stops. When the worm gear stops rotating and engages with the worm wheel to form a self-locking mechanism, the rotation of the seat cushion is fixed, thus keeping the seat cushion horizontal and moving downwards. Conversely, when the guide seat moves upwards, it drives the seat cushion horizontally upwards. At this time, the guide hemisphere slides upwards along the limiting guide groove. When the guide seat moves upwards above the seat height, the guide hemisphere slides into the spiral guide groove. At this time, the guide seat moves upwards again, causing the guide hemisphere to slide in the opposite direction along the spiral guide groove, thus causing the worm gear to rotate in the opposite direction. The reverse rotation of the worm gear meshes with the worm wheel, driving the worm wheel to rotate counterclockwise, which in turn drives the seat cushion to rotate counterclockwise.

[0017] In one embodiment, each of the two sets of support legs is equipped with a movable component, which includes a mounting block, casters, and an electric telescopic rod. A through-groove is formed vertically on each support leg, and the bottom end of the mounting block passes through the groove and is equipped with multiple casters. Mounting holes are formed at both ends of each support leg, and an electric telescopic rod is vertically installed in each of the mounting holes. The telescopic ends of the two sets of electric telescopic rods are respectively connected to the two ends of the mounting block. When the two sets of electric telescopic rods retract, the multiple casters protrude from the bottom of the support leg. By controlling the retraction of the multiple sets of electric telescopic rods to move the two sets of mounting blocks downwards, the multiple casters protrude from the bottom of the support leg, thereby contacting the casters with the ground and separating the support leg from the ground, facilitating the movement of the device. When the device moves to a suitable position, controlling the extension of the multiple sets of electric telescopic rods to separate the casters from the ground and bring the support leg into contact with the ground secures the device. The device is easy to move and fix.

[0018] In one embodiment, the guide seat is further provided with a support mechanism, which includes a support plate and a lifting assembly. The support plate is located above both ends of the guide seat, and both sets of support plates are connected to the guide seat via the lifting assembly. Adjusting the lifting assembly drives the support plates to rise and fall. By providing two sets of support plates, it is easier for elderly people to place their arms on the support plates, improving their stability during squatting and standing. Furthermore, adjusting the lifting assembly to drive the support plates to rise and fall allows for adjustment of the support height according to the different needs of elderly people, enhancing the practicality of the device.

[0019] In one embodiment, the lifting assembly includes a second screw; a limit rod is vertically disposed at the bottom end of the support plate, the limit rod being slidably mounted on the guide seat in a vertical direction; the top end of the second screw is rotatably disposed on the support plate and parallel to the limit rod; the bottom end of the second screw is threadedly connected to the guide seat. Rotating the second screw in connection with the guide seat threadedly causes the second screw to move the support plate upwards; rotating the second screw in the opposite direction in connection with the guide seat threadedly causes the second screw to move the support plate downwards. This facilitates lifting and lowering the support plate, and stopping the rotation of the second screw in connection with the guide seat threadedly forms a self-locking mechanism, thereby fixing the support plate conveniently.

[0020] In one embodiment, the support mechanism further includes an auxiliary mechanism comprising a gripping rod and a moving component. The gripping rod is positioned above both sets of support plates, and both sets of gripping rods are connected to the support plates via the moving component. Adjusting the moving component drives the gripping rod to move along the length of the support plate. When an elderly person places their arm on the support plate, they can grasp the gripping rod, which not only improves the stability of the arm on the support plate but also facilitates the elderly person's hand exertion, thus providing some assistance with defecation. Furthermore, by adjusting the moving component to drive the gripping rod to move along the length of the support plate, the position of the gripping rod can be adjusted according to the arm length, making it suitable for different elderly people and improving the practicality of the device.

[0021] In one embodiment, the moving component includes a guide block and a third screw; a T-shaped groove is formed on one side of the support plate, and a T-shaped slider is provided at one end of the guide block. The T-shaped slider can slide along the length of the support plate within the T-shaped groove. The gripping rod is disposed on the guide block, and the third screw is rotatably disposed on the support plate and parallel to the support plate. The third screw is threadedly connected to the T-shaped slider. By rotating the third screw and engaging the threaded connection with the T-shaped slider, the T-shaped slider can be driven to move, thereby moving the guide block and the gripping rod. By rotating the third screw and engaging the threaded connection with the T-shaped slider in the opposite direction, the T-shaped slider can be driven to move, thereby moving the guide block and the gripping rod in the opposite direction. Driving the gripping rod is convenient, and stopping the rotation of the third screw and engaging the threaded connection with the T-shaped slider forms a self-locking mechanism, thereby fixing the gripping rod. Fixing the gripping rod is convenient.

[0022] In one embodiment, the support mechanism further includes an anti-tilting mechanism, which includes a stop bar and a locking assembly. Each of the two sets of support plates has a vertical connecting shaft at its bottom end away from the guide seat. The stop bar is rotatably mounted on each of the two connecting shafts. The locking assembly connects the stop bar to the connecting shaft and secures the stop bar when it is pressed. In use, a horizontal force is applied to the two sets of stop bars, causing them to rotate in front of the elderly person and positioned between the two support plates. When the elderly person leans forward and applies pressure to the stop bars, the locking assembly secures them, thus preventing the elderly person from accidentally falling forward and improving their safety when using the toilet. When not in use, a horizontal force is applied to the two sets of stop bars, causing them to rotate below the two support plates for easy storage.

[0023] In one embodiment, the locking assembly includes a limiting plate and a spring; one end of the stop lever has a connecting hole, which is sleeved on the connecting shaft. The limiting plate is coaxially disposed at the bottom end of the connecting shaft. The spring is sleeved on the connecting shaft, and its two ends respectively abut against the limiting plate and the stop lever. Multiple sets of fixing blocks are evenly arranged around the bottom end of the stop lever in the circumferential direction of the connecting shaft. Multiple sets of fixing slots are evenly arranged along the circumferential direction of the limiting plate, and the multiple sets of fixing blocks can pass through the multiple sets of fixing slots. When the stop lever is pressed, it moves downward, compressing the spring and causing the multiple sets of fixing blocks to pass through the multiple sets of fixing slots, thus fixing the stop lever. When the pressure on the stop lever is released, the reaction force of the spring causes the stop lever to move upward, separating the multiple sets of fixing blocks from the multiple sets of fixing slots, at which point the stop lever can be rotated. Fixing and rotating the stop lever is convenient. Attached Figure Description

[0042] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0043] Please see Figures 1 to 4 One embodiment of a multifunctional squat toilet for the elderly includes a base 10, a guide seat 20, a drive assembly, and a transmission assembly.

[0044] The base 10 has legs 101 at both ends, and two sets of guide pillars 102 are vertically mounted on the top of the base 10. The tops of the two sets of guide pillars 102 are connected to a backrest 103. A guide seat 20 is slidably mounted on the two sets of guide pillars 102 in a vertical direction. A seat cushion 201 is rotatably mounted on the guide seat 20, located between the two sets of legs 101. The seat cushion 201 has a through-hole drainage groove 202 along its thickness direction. A drive assembly is mounted on the backrest 103 and connected to the guide seat 20, and is used to drive the guide seat 20 to move up and down. The transmission assembly connects the base 10, the guide seat 20, and the seat 201. When the guide seat 20 moves downward, it can drive the seat 201 to rotate clockwise through the transmission assembly. When the guide seat 20 moves downward to the seat height, the seat 201 is level. When the guide seat 20 is below the seat height, the seat 201 remains level. When the guide seat 20 moves upward, it can drive the seat 201 to move upward while remaining level through the transmission assembly. When the guide seat 20 is above the seat height, it drives the seat 201 to rotate counterclockwise.

[0045] In the above embodiment, by placing the buttocks and back against the seat cushion 201 and backrest 103 respectively, the control drive assembly drives the guide seat 20 to move downwards. The downward movement of the guide seat 20 causes the seat cushion 201 to move downwards and, through the transmission assembly, drives the seat cushion 201 to rotate clockwise. When the guide seat 20 moves downwards to the sitting height so that the seat cushion 201 is horizontal, the seat cushion 201 can support the elderly person to change from a standing to a sitting position. As the drive assembly drives the guide seat 20 to continue moving downwards below the sitting height, the guide seat 20 causes the seat cushion 201 to move downwards and, through the transmission assembly, keeps the seat cushion 201 horizontal. The horizontal downward movement of the seat cushion 201 can support the elderly person to change from a standing to a sitting position. When transitioning from a sitting to a squatting position, and vice versa, the drive assembly moves the guide seat 20 upwards. The guide seat 20 then moves the seat cushion 201 horizontally upwards. When the guide seat 20 reaches the sitting height, the seat cushion 201 supports the elderly person transitioning from a squatting to a sitting position. As the drive assembly continues to move the guide seat 20 upwards above the sitting height, the guide seat 20 moves the seat cushion 201 upwards and, through the transmission assembly, drives the seat cushion 201 to rotate counter-clockwise. This upward movement and counter-clockwise rotation of the seat cushion 201 supports the elderly person transitioning from a sitting to a standing position, thus facilitating squatting and standing assistance during toileting and improving comfort and safety. Simply controlling the guide seat 20 to move it downwards or upwards allows the seat cushion 201 to support the elderly person's posture changes from standing to sitting and then to squatting, or vice versa. The operation is simple and convenient, further enhancing the comfort of squatting and standing for the elderly. When the guide seat 20 is lower than the sitting height, the height of the seat cushion 201 can be adjusted by controlling the guide seat 20 to move up or down through the drive component. This makes it easy to adjust the height of the squat toilet according to needs, making it convenient for different elderly people to use and improving the practicality of the device.

[0046] Please refer to the following: Figure 6 Specifically, in the above embodiments, the drive assembly includes a first screw 30 and a motor 301; the first screw 30 is rotatably mounted on the backrest 103 and parallel to the guide post 102, the bottom end of the first screw 30 is threadedly connected to the guide seat 20, the motor 301 is mounted on the backrest 103, and its output end is coaxially connected to the first screw 30 through a coupling.

[0047] By controlling the motor 301 to drive the first screw 30 to rotate, the rotation of the first screw 30 engages with the threaded engagement of the guide seat 20, thus driving the guide seat 20 to move downwards. By controlling the motor 301 to drive the first screw 30 to rotate in the opposite direction, the first screw 30 engages with the threaded engagement of the guide seat 20, thus driving the guide seat 20 to move upwards. Driving the guide seat 20 to move up and down is convenient. Furthermore, by controlling the motor 301 to stop driving the first screw 30 to rotate, the first screw 30 stops rotating and forms a threaded self-locking mechanism with the guide seat 20 to fix the guide seat 20, making it easy to fix the guide seat 20.

[0048] Please refer to the following: Figure 6 and Figure 7 Specifically, in the above embodiments, the transmission assembly includes a worm 40, a worm wheel 401, and a guide shaft 402. The worm 40 is rotatably mounted on the guide seat 20. A rotating shaft 203 is horizontally mounted at one end of the seat 201. The rotating shaft 203 is rotatably mounted on the guide seat 20. The worm wheel 401 is coaxially mounted at one end of the rotating shaft 203 and meshes with the worm 40. The guide shaft 402 is vertically mounted on the base 10. The worm 40 is coaxially sleeved on the guide shaft 402. A spiral guide groove 403 is opened on the upper circumference of the guide shaft 402. A limiting guide groove 404 is opened on the lower circumference of the guide shaft 402 in the vertical direction. The bottom end of the spiral guide groove 403 communicates with the top end of the limiting guide groove 404. A guide hemisphere 405 is provided inside the worm 40. The guide hemisphere 405 is slidably mounted in the spiral guide groove 403 and the limiting guide groove 404.

[0049] When the guide seat 20 moves downward, it drives the seat cushion 201, worm gear 40, and worm wheel 401 to move downward. The downward movement of the worm gear 40 causes the guide hemisphere 405 to slide along the spiral guide groove 403. The sliding of the guide hemisphere 405 along the spiral guide groove 403 drives the worm gear 40 to rotate. The rotation of the worm gear 40 meshes with the worm wheel 401, driving the worm wheel 401 to rotate clockwise. The clockwise rotation of the worm wheel 401 drives the seat cushion 201 to rotate clockwise. When the guide seat 20 moves downward to the seating height, the seat cushion 201 is horizontal, and the guide hemisphere 405 is located at the connection between the spiral guide groove 403 and the limiting guide groove 404. When the guide seat 20 continues to move downward, it drives the seat cushion 201 to move downward, and causes the guide hemisphere 405 to slide downward along the limiting guide groove 404. When the worm 40 stops rotating, it engages with the worm wheel 401 to form a self-locking mechanism, thus fixing the rotation of the seat cushion 201 and keeping it horizontal as it moves downwards. Conversely, when the guide seat 20 moves upwards, it drives the seat cushion 201 to move horizontally upwards. At this time, the guide hemisphere 405 slides upwards along the limiting guide groove 404. When the guide seat 20 moves upwards above the seat height, the guide hemisphere 405 slides into the spiral guide groove 403. At this time, the guide seat 20 moves upwards, causing the guide hemisphere 405 to slide in the opposite direction along the spiral guide groove 403, thereby causing the worm 40 to rotate in the opposite direction. The reverse rotation of the worm 40 engages with the worm wheel 401, driving the worm wheel 401 to rotate counterclockwise. The counterclockwise rotation of the worm wheel 401 drives the seat cushion 201 to rotate counterclockwise.

[0050] Please see Figure 1 and Figure 5 In one embodiment, each of the two sets of support legs 101 is provided with a movable component, which includes a mounting block 104, casters 105, and an electric telescopic rod 106. The support leg 101 has a through storage groove 1011 in the vertical direction. The bottom end of the mounting block 104 passes through the storage groove 1011 and is provided with multiple sets of casters 105. Both ends of the support leg 101 are provided with mounting holes 1012. An electric telescopic rod 106 is vertically arranged in both sets of mounting holes 1012. The telescopic ends of the two sets of electric telescopic rods 106 are respectively connected to the two ends of the mounting block 104. When the two sets of electric telescopic rods 106 are retracted, the multiple sets of casters 105 can protrude from the bottom end of the support leg 101.

[0051] In the above embodiment, by controlling the retraction of multiple sets of electric telescopic rods 106 to move the two sets of mounting blocks 104 downward, multiple sets of casters 105 can protrude from the bottom of the support leg 101, thereby making the multiple sets of casters 105 contact the ground and separating the support leg 101 from the ground, thus facilitating the movement of the device. When the device is moved to a suitable position, controlling the extension of multiple sets of electric telescopic rods 106 to separate the multiple sets of casters 105 from the ground and make the support leg 101 contact the ground can fix the device. The device is easy to move and fix.

[0052] Please see Figure 1 , Figure 4 and Figure 8 In one embodiment, a support mechanism is also provided on the guide seat 20. The support mechanism includes a support plate 50 and a lifting component. Support plates 50 are provided on both ends of the guide seat 20. Both sets of support plates 50 are connected to the guide seat 20 through the lifting component. Adjusting the lifting component can drive the support plates 50 to rise and fall.

[0053] In the above embodiments, by setting two sets of support plates 50, it is convenient for the elderly to place their arms on the support plates 50, which can improve the stability of the elderly during squatting and standing. In addition, the lifting component can be adjusted to drive the support plates 50 to rise and fall, so as to adjust the support height of the support plates 50 according to the different needs of the elderly, thereby improving the practicality of the device.

[0054] Specifically, in the above embodiments, the lifting assembly includes a second screw 501; a limit rod 502 is vertically provided at the bottom end of the support plate 50, the limit rod 502 can slide along the vertical direction and pass through the guide seat 20, the top end of the second screw 501 is rotatably provided on the support plate 50 and is arranged parallel to the limit rod 502, and the bottom end of the second screw 501 is threadedly connected to the guide seat 20.

[0055] By rotating the second screw 501 and engaging it with the guide seat 20, the second screw 501 can drive the support plate 50 to move upward. By rotating the second screw 501 and engaging it with the guide seat 20 in the opposite direction, the second screw 501 can drive the support plate 50 to move downward. This makes it easy to drive the support plate 50 to rise and fall. Furthermore, stopping the rotation of the second screw 501 and engaging it with the guide seat 20 will create a self-locking mechanism, thereby fixing the support plate 50. This makes fixing the support plate 50 convenient.

[0056] Please see Figure 1 , Figure 4 and Figure 8 In one embodiment, the support mechanism further includes an auxiliary mechanism, which includes a gripping rod 60 and a moving component. Both sets of support plates 50 are provided with gripping rods 60. Both sets of gripping rods 60 are connected to the support plates 50 through the moving component. Adjusting the moving component can drive the gripping rods 60 to move along the length direction of the support plates 50.

[0057] In the above embodiment, when the elderly person places their arm on the support plate 50, they can grasp the holding rod 60. This not only improves the stability of the arm on the support plate 50, but also makes it easier for the elderly person to apply force with their hand, which can play a certain role in assisting defecation. At the same time, by adjusting the moving component, the holding rod 60 can be driven to move along the length of the support plate 50, making it easy to adjust the position of the holding rod 60 according to the arm length, making it easy for different elderly people to use and improving the practicality of the device.

[0058] Specifically, in the above embodiments, the moving component includes a guide block 601 and a third screw 602; a T-shaped groove 503 is provided on one side of the support plate 50, a T-shaped slider 603 is provided at one end of the guide block 601, the T-shaped slider 603 can slide along the length direction of the support plate 50 and is disposed in the T-shaped groove 503, the gripping rod 60 is disposed on the guide block 601, the third screw 602 is rotatably disposed on the support plate 50 and parallel to the support plate 50, and the third screw 602 is threadedly connected to the T-shaped slider 603.

[0059] By rotating the third screw 602 and engaging the threaded connection with the T-slider 603, the T-slider 603 can be driven to move, thus moving the guide block 601 and the gripping rod 60. By rotating the third screw 602 and engaging the threaded connection with the T-slider 603 in the opposite direction, the T-slider 603 can be driven to move, thus moving the guide block 601 and the gripping rod 60 in the opposite direction. Driving the gripping rod 60 is convenient, and stopping the rotation of the third screw 602 and engaging the threaded connection with the T-slider 603 will form a self-locking mechanism, thereby fixing the gripping rod 60. Fixing the gripping rod 60 is convenient.

[0060] Please see Figure 1 , Figure 3 , Figure 8 and Figure 9 In one embodiment, the support mechanism further includes an anti-tilting mechanism, which includes a stop bar 70 and a locking assembly. The bottom ends of the two sets of support plates 50 away from the guide seat 20 are vertically connected to a connecting shaft 504. The stop bar 70 is rotatably provided on both sets of connecting shafts 504. A locking assembly is connected between the stop bar 70 and the connecting shaft 504. The locking assembly is used to fix the stop bar 70 when it is pressed.

[0061] In the above embodiment, by applying a horizontal force to the two sets of stop levers 70, the two sets of stop levers 70 are rotated to the front of the elderly person's body and located between the two sets of support plates 50. When the elderly person leans forward and applies pressure to the two sets of stop levers 70, the locking component can fix the two sets of stop levers 70, thereby blocking the body and preventing the elderly person from falling forward due to accident, thus further improving the safety of the elderly person when using the toilet. When not in use, the two sets of stop levers 70 can be stored by applying a horizontal force to the two sets of stop levers 70 and rotating them to the bottom of the two sets of support plates 50. The storage of the two sets of stop levers 70 is convenient.

[0062] Specifically, in the above embodiments, the locking assembly includes a limiting plate 701 and a spring 702; a connecting hole 705 is provided at one end of the stop rod 70, the connecting hole 705 is sleeved on the connecting shaft 504, the limiting plate 701 is coaxially provided at the bottom end of the connecting shaft 504, the spring 702 is sleeved on the connecting shaft 504, and its two ends abut against the limiting plate 701 and the stop rod 70 respectively, and multiple sets of fixing blocks 703 are evenly arranged around the bottom end of the stop rod 70 around the connecting shaft 504, and multiple sets of fixing slots 704 are evenly opened along the circumference of the limiting plate 701, and the multiple sets of fixing blocks 703 can be inserted into the multiple sets of fixing slots 704.

[0063] When the stop lever 70 is pressed, it moves downward to compress the spring 702 and cause multiple sets of fixing blocks 703 to pass through multiple sets of fixing slots 704, thus fixing the stop lever 70. When the pressure on the stop lever 70 is released, the reaction force of the spring 702 causes the stop lever 70 to move upward and causes the multiple sets of fixing blocks 703 to separate from the multiple sets of fixing slots 704, at which point the stop lever 70 can be rotated. Fixing and rotating the stop lever 70 is convenient.

[0064] The specific implementation method of the above-mentioned multifunctional squat toilet for the elderly is as follows:

[0065] In use, the buttocks and back are rested on the seat cushion 201 and backrest 103 respectively. The motor 301 drives the first screw 30 to rotate. The rotation of the first screw 30 engages with the guide seat 20 via a thread, causing the guide seat 20 to move downwards. This downward movement of the guide seat 20 causes the seat cushion 201, worm gear 40, and worm wheel 401 to move downwards. The downward movement of the worm gear 40 causes the guide hemisphere 405 to slide along the spiral guide groove 403. This sliding motion of the guide hemisphere 405 drives the worm gear 40 to rotate. The rotation of the worm gear 400 engages with the worm wheel 401, causing the worm wheel 401 to rotate clockwise. The clockwise rotation of the worm wheel 401 causes the seat cushion 201 to rotate clockwise. When the guide seat 20 moves downward to the sitting height, the guide hemisphere 405 is located at the connection between the spiral guide groove 403 and the limiting guide groove 404. At the same time, the seat cushion 201 is horizontal, thus allowing the seat cushion 201 to support the elderly person from a standing position to a sitting position. When the guide seat 20 continues to move downward, the guide seat 20 drives the seat cushion 201 to move downward, and the guide hemisphere 405 slides downward along the limiting guide groove 404. At this time, the worm gear 40 stops rotating. The worm gear 40 stops rotating and cooperates with the worm wheel 401 to form a self-locking mechanism, which can fix the rotation of the seat cushion 201, thus keeping the seat cushion 201 in a horizontal state as it moves downward. The horizontal downward movement of the seat cushion 201 can support the elderly person from a sitting position to a squatting position.

[0066] Conversely, by controlling the motor 301 to drive the first screw 30 to rotate in the opposite direction, the first screw 30 rotates in the opposite direction and engages with the guide seat 20 threadedly, thus driving the guide seat 20 to move upward. The guide seat 20 moves upward, causing the seat cushion 201 to move horizontally upward. At this time, the guide hemisphere 405 slides upward along the limiting guide groove 404. When the guide seat 20 moves upward to the sitting height, the seat cushion 201 supports the elderly person from a squatting position to a sitting position. When the guide seat 20 continues to move upward above the sitting height, the guide hemisphere 405 slides in the opposite direction along the spiral guide groove 403, thereby causing the worm gear 40 to rotate in the opposite direction. The reverse rotation of the worm gear 40 meshes with the worm wheel 401, thus driving the worm wheel 401 to rotate counterclockwise. The counterclockwise rotation of the worm wheel 401 drives the seat cushion 201 to rotate counterclockwise. The seat cushion 201 moves upward and rotates counterclockwise, thus supporting the elderly person from a sitting position to a standing position. This facilitates assistance for the elderly person when squatting and standing while using the toilet, improving the comfort and safety of the elderly person when using the toilet. Furthermore, by controlling the motor 301 to drive the first screw 30 to rotate and move the guide seat 20 downwards or upwards, the seat cushion 201 can support the elderly person in changing postures from standing to sitting and then to squatting, or vice versa. This simple and convenient operation further improves the comfort of the elderly person when squatting and standing. Simultaneously, when the guide seat 20 is lower than the sitting height, controlling the motor 301 to drive the first screw 30 to rotate and move the guide seat 20 downwards or upwards adjusts the height of the seat cushion 201 in a horizontal position. This allows for easy adjustment of the squatting height according to needs, making it suitable for different elderly people and improving the practicality of the device.
