Description

Technical Field

[0001] This application relates to the field of toilet technology, such as a backrest for a toilet lifter and a toilet lifter. Background Technology

[0002] Currently, toilets are common sanitary facilities. During use, users need to bend over, sit on the toilet, and then stand up. For the elderly, pregnant women, and people with disabilities, this requires considerable time and effort. Prolonged sitting can easily cause leg numbness, making it even more difficult to get up. Toilet lifters are assistive devices specifically designed for the elderly, pregnant women, and people with disabilities to help them get up more easily when using the toilet. Existing toilet lifters are mostly grab bars on the sides of the toilet, without support for the user's back, making it difficult to brace and resulting in a poor user experience.

[0003] One related technology includes a toilet seat lifter comprising a base and a seat backrest. The base includes a supporting seat ring and a supporting frame. The seat backrest is rotatably connected to the supporting frame and can be placed on the supporting seat ring. The seat backrest provides back support to the user, improving the user experience.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] Because the cover backrest needs to cover the support seat ring, the contact surface between the cover backrest and the user is relatively flat, the support area is small, and the comfort is poor.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0039] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0040] Combination Figure 1-2As shown, this embodiment of the present disclosure provides a backrest for a toilet seat lifter, including: a back panel 100 and a fixing member 200. The back panel 100 includes a support portion 110 and a side support portion 120, the side support portion 120 protruding from the support portion 110 toward the front side of the back panel 100; one end of the fixing member 200 is fixedly connected to the back side of the support portion 110, and the other end is connected to the toilet seat lifter; wherein, the back panel 100 has a first angle 101 with the horizontal plane, and the first angle 101 is an obtuse angle.

[0041] The backrest for a toilet seat lifter provided in this embodiment of the present disclosure provides support for the user by means of the side support portion 120 protruding from the support portion 110 towards the front of the back panel 100, and the support portion 110 and the side support portion 120 working together. The support contact area is relatively large, and the support directions are more numerous, resulting in relatively high comfort.

[0042] Optionally, the first included angle 101 is greater than 90 degrees and less than or equal to 110 degrees. When the first included angle 101 is less than 90 degrees, the backrest 100 tilts forward, making it easy for the user's back to lean forward, resulting in poor seating comfort. When the first included angle 101 is greater than 110 degrees, the angle of backward leaning is too large, making it difficult for the user to get up. Therefore, the range of the first included angle being greater than 90 degrees and less than or equal to 110 degrees is more reasonable, reducing the risk of the user leaning forward and making it difficult to get up.

[0043] Optionally, the first included angle 101 is 108 degrees or 102 degrees. In this way, the risk of the user leaning forward while resting on the back panel 100 is lower, and the risk of the user having difficulty getting up is also lower.

[0044] Optionally, the support portion 110 is provided with side supports 120 on both opposite sides, and the length of the side supports 120 is less than the length of the support portion 110. In this way, when the user leans against the back panel 100, the relatively shorter length of the side supports 120 allows for more space for the user's arms to move. Furthermore, the relatively longer length of the support portion 110 provides a larger support area for the user to lean against, improving the user experience.

[0045] Optionally, the length of the support portion 110 is equal to 1.8 times the length of the side support portion 120. This way, when the user leans against the back panel 100, the relatively shorter length of the side support portion 120 allows for more arm movement. Furthermore, the relatively longer length of the support portion 110 provides a larger support area for the user, improving the user experience.

[0046] Combination Figure 2As shown, optionally, the fixing member 200 includes a connecting plate 210 and an arc-shaped rod 220. The connecting plate 210 is fixedly connected to the back side of the support part 110; the top end of the arc-shaped rod 220 is fixedly connected to the connecting plate 210, and the bottom end is connected to the toilet lifter. In this way, the connection between the arc-shaped rod 220 and the toilet lifter is relatively strong, allowing the connecting plate 210 and the back plate 100 to be set at a relatively high height, resulting in a better user experience.

[0047] Optionally, the curved bar 220 is made of an elastic material. In this way, the curved bar 220 is elastic, and when the user leans against the back panel 100, the curved bar 220 will undergo elastic deformation, providing elastic cushioning for the user and improving the user experience.

[0048] Specifically, the curved rod 220 is made of ABS plastic (Acrylonitrile Butadiene Styrene plastic).

[0049] Optionally, the connecting plate 210 and the arc-shaped rod 220 are integrally formed. In this way, the connection strength between the connecting plate 210 and the arc-shaped rod 220 is relatively high, providing better support stability for the back plate 100.

[0050] Specifically, the curved rod 220 bends toward one side of the back plate 100.

[0051] Optionally, the bottom end of the curved rod 220 is fixedly connected to the sliding rod 230, and the sliding rod 230 is slidably connected to the toilet lifter in the horizontal direction. In this way, the sliding rod 230 can slide relative to the toilet lifter, adjusting the distance between the backrest 100 and the toilet lifter, thereby adjusting the seat depth to meet the needs of users of different body types and provide better adaptability.

[0052] Optionally, the front side of the support 110 and the side of the side support 120 that connects to the front side of the support 110 are both curved surfaces. In this way, the transition at the connection between the support 110 and the side support 120 is more natural, and it can fit the user's body better when the user leans against it, increasing the support area and improving the user's comfort.

[0053] Optionally, the back panel 100 is C-shaped. In this way, the back panel 100 can better surround the user's back and provide support for the user's sides. When the user leans against it, it can fit the user's body more closely, increase the support area, and improve the user's comfort.

[0054] Optionally, the back panel 100 is made of an antimicrobial material. In this way, the back panel 100 made of antimicrobial material can reduce the growth of bacteria, making it healthier and safer in direct contact with the back panel 100.

[0055] Optionally, the back panel 100 is made of polypropylene (PP) with a silver ion coating. This silver ion coating effectively reduces bacterial growth, making it healthier and safer in direct contact with the back panel 100. Furthermore, the back panel 100, made of plastic, is relatively lightweight and has a relatively low thermal conductivity, improving user comfort.

[0056] Combination Figure 3 As shown, optionally, a heating element 300 is provided inside the back panel 100. When the heating element 300 is provided in the back panel 100, the heating element 300 heats the back panel 100 and conducts the heat to the back panel 100, increasing the temperature of the back panel 100. This makes the temperature of the back panel 100 closer to or slightly higher than the user's body temperature, improving user comfort.

[0057] Alternatively, the heating element 300 can be an electric heating element 310. This reduces the required size of the electric heating element 310 and allows for more flexible design.

[0058] Understandably, the heating element 300 can also be other conventional heating components such as an electric heating rod, an electric heating wire, or a semiconductor heating plate.

[0059] In some embodiments, a toilet lifter includes a backrest for a toilet lifter as described in the above embodiments.

[0060] The toilet lifter provided in this embodiment includes a backrest as described in the previous embodiment. The side support portion 120 protrudes from the support portion 110 towards the front of the back panel 100, and the support portion 110 and the side support portion 120 together provide support for the user. The support contact area is relatively large, and the support directions are more numerous, resulting in relatively high comfort.

[0061] Optionally, the toilet seat lifter also includes a lift seat 400. The lift seat 400 is provided with a mounting portion 410 that connects to the fixing member 200. In this way, the connection between the mounting portion 410 and the fixing member 200 is relatively stable.

[0062] Specifically, the sliding rod 230 is slidably connected to the mounting part 410 of the seat 400. In this way, the sliding rod 230 slides relative to the mounting part 410, thereby adjusting the distance between the back panel 100 and the seat 400, and thus adjusting the seat depth to meet the needs of users of different body types, providing better adaptability.

[0063] Optionally, the mounting part 410 is a mounting hole 411, which is located at the bottom of the seat 400 and is slidably connected to the sliding rod 230. In this way, the sliding rod 230 slides within the mounting hole 411 to adjust the distance between the back plate 100 and the seat 400, thereby adjusting the seat depth to meet the needs of users of different body types and provide better adaptability.

[0064] Combination Figure 4 As shown, optionally, the assisted sitting seat 400 includes a seat body 420 and a support base 430. Each side of the seat body 420 is connected to a support base 430, and there is an installation gap 401 between the two support bases 430. A sliding rod 230 is slidably connected to the seat body 420. Thus, the space between the installation gaps 401 can be used to place a toilet, allowing the user to sit directly on the seat body 420. Furthermore, the support bases 430 and the seat body 420 can be removed from the toilet to allow for normal toilet use, eliminating the need for a fixed handrail on the wall and making it more flexible to use.

[0065] Specifically, mounting hole 411 is provided on base 420.

[0066] Combination Figure 5 As shown, optionally, each support base 430 is provided with a support foot 431 at its bottom, and the bottom side of the support foot 431 is provided with an elastic anti-slip element 432. This reduces the risk of the support base 430 sliding, and the sound of moving the support base 430 is relatively small. The elastic anti-slip element 432 is elastic and provides elastic cushioning when the user sits on the seat 420, improving comfort.

[0067] Optionally, the elastic anti-slip component 432 is made of rubber. In this way, the elastic anti-slip component 432 is more wear-resistant and less prone to aging.

[0068] Specifically, each support base 430 has two support feet 431 at its bottom. This provides relatively good stability for the support.

[0069] Optionally, the seat ring 470 is made of an antibacterial material. This reduces bacterial growth, making the seat ring 470 healthier and safer when the user is in direct contact with it.

[0070] Optionally, the seat ring 470 is made of polypropylene (PP) with a silver ion coating. This silver ion coating effectively reduces bacterial growth, making it healthier and safer in direct contact with the seat ring 470. Furthermore, the plastic material of the seat ring 470 makes it relatively lightweight and has a relatively low thermal conductivity, improving user comfort. Reducing the overall weight of the toilet lifter also makes it easier to move around.

[0071] Specifically, the width of the seat ring 470 is less than or equal to the width of the installation interval 401. This allows for a relatively large installation interval 401, accommodating toilets of different sizes.

[0072] Optionally, the toilet lift assist also includes a support arm 440 and a handrail 450. One end of the support arm 440 is a connecting end 441, and the other end is a handrail end 442. The connecting end 441 is rotatably connected to the seat 420. One end of the handrail 450 is fixedly connected to the handrail end 442, and a second included angle 443 exists between the handrail 450 and the support arm 440; wherein the second included angle 443 is an acute angle. Thus, pulling the handrail end 442 of the support arm 440 causes the support arm 440 to rotate relative to the toilet lift assist, forming a force-saving lever requiring relatively little force. When the handrail 450 is rotated to a horizontal position, stopping the pulling of the handrail end 442 allows the handrail 450 to provide support for the user. Furthermore, the acute included angle 443 between the handrail 450 and the support arm 440 means that the angle of rotation required to rotate the handrail 450 to a horizontal position is relatively small, resulting in a better user experience.

[0073] Optionally, the second included angle 443 is equal to 25 degrees. This way, pulling the handrail end 442 causes the support arm 440 to rotate, resulting in a smaller angle required for the handrail board 450 to rotate to a horizontal position. Furthermore, the handrail board 450 can be raised to a relatively high height, providing a suitable support height for the user and improving the user experience. Additionally, the handrail board 450 can be set to a relatively long length, providing a larger support area for the user.

[0074] Understandably, when the handrail 450 is in a horizontal position, the angle between the support arm 440 and the horizontal plane is equal to the second angle 443.

[0075] Optionally, when the armrest board 450 is in a horizontal position, the armrest end 442 of the support arm 440 is higher than the armrest board 450. This makes the armrest end 442 of the support arm 440 relatively high, thus making it more prominent. This provides a gripping point for the user, making the grip more comfortable.

[0076] Optionally, the rotatable connection between the connecting end 441 and the seat 420 has a damping force. Thus, when the armrest plate 450 is rotated to a horizontal position, the rotating support arm 440 needs to overcome the damping force, while providing support to the user through the damping force, thereby improving the user's comfort.

[0077] Optionally, the handrail end 442 of the armrest panel 450 and / or support arm 440 is made of antibacterial material. This is because the handrail panel 450 and the handrail end 442 of the support arm 440 are areas frequently touched by the user. Therefore, the handrail panel 450 and / or support arm 440 made of antibacterial material can reduce bacterial growth, making direct contact with the handrail end 442 of the handrail panel 450 and / or support arm 440 healthier and safer.

[0078] Optionally, the armrest end 442 of the armrest panel 450 and / or support arm 440 is made of plastic and has a silver ion coating on its surface. This silver ion coating effectively reduces bacterial growth, making it healthier and safer in direct contact with the armrest end 442 of the armrest panel 450 and / or support arm 440. Furthermore, the armrest end 442 of the armrest panel 450 and / or support arm 440, made of plastic, is relatively lightweight and has a relatively low thermal conductivity, improving user comfort.

[0079] Alternatively, the length of the support arm 440 is equal to 1.5 times the length of the handrail 450. This reduces the risk of the support arm 440 protruding from the toilet lifter, and allows the support arm 440 to be lifted to a relatively high height when the handrail end 442 is pulled.

[0080] Combination Figure 6 As shown, optionally, the seat body 420 is provided with connecting portions 460 on both opposite sides, and each connecting portion 460 can be rotatably connected to the connecting end 441. In this way, support arms 440 can be installed on both sides of the seat body 420, providing better support for the user through a greater number of support arms 440 and armrests 450.

[0081] Optionally, the connecting part 460 includes a mounting plate 461. One end of the mounting plate 461 is fixedly connected to the base 420, and one side of the mounting plate 461 is connected to the connecting end 441. In this way, by connecting the mounting plate 461 to the connecting end 441 of the support arm 440, the connection area with the connecting end 441 is increased, and the stability of the connection is improved.

[0082] Combination Figure 7 As shown, optionally, the seat body 420 is provided with a seat ring 470, and two mounting plates 461 are disposed on opposite sides of the seat ring 470. In this way, the user can sit directly on the seat ring 470, which provides relatively high comfort.
