Description

Technical Field

[0001] This invention relates to the field of electronic toilet technology, and in particular to a liftable electronic toilet and a lifting method thereof. Background Technology

[0002] As an innovative product in the modern bathroom industry, the core demand for smart toilets stems from consumers' dual pursuit of hygiene and comfort. Market research indicates that the primary motivation for consumers choosing smart toilets is to improve the hygienic environment, followed by the enhanced comfort experience brought by functional expansion. However, existing smart toilet seats have significant structural design flaws: traditional smart toilet seats only allow the front half to flip, while the rear half is fixed to the toilet body. However, a gap exists between the fixed part and the toilet body, leading to the formation of hard-to-clean areas.

[0003] Specifically, during daily use, contaminants such as urine and water stains can easily seep into the crevices. Because these cannot be thoroughly cleaned, they gradually accumulate, breeding bacteria and producing odors. This problem is particularly pronounced when male users are part of the household. Long-term accumulation of grime not only affects the bathroom environment but may also pose a potential threat to the user's health.

[0004] It should be noted that the information disclosed in this background section is intended only to enhance the understanding of the overall background of the present invention, and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] To address the technical problem of dirt and grime accumulating in the gap between the fixed part and the body of conventional electronic toilet seats, this invention provides a height-adjustable electronic toilet seat, comprising: ontology; A cover body, wherein the cover body is disposed on the main body; The lifting assembly includes a first slide block disposed on the cover, a second slide block disposed on the main body, and a first support arm and a second support arm hinged to each other between the first slide block and the second slide block. The first slide block and the second slide block are respectively provided with a first slide groove and a second slide groove. The hinged end of the first support arm is hinged to the first slide block, and the sliding end of the first support arm is slidably connected to the second slide groove. The hinged end of the second support arm is hinged to the second slide block, and the sliding end of the second support arm is slidably connected to the first slide groove. The lifting assembly can switch between a first lifting state and a second lifting state. When switching the lifting state, the sliding ends of the first support arm and the second support arm are displaced in the same direction along the setting direction of the second slide groove and the first slide groove, respectively. The distance between the first slide block and the second slide block is changed by increasing or decreasing the angle of the hinge between the first support arm and the second support arm, thereby driving the cover to move up and down relative to the body.

[0006] Furthermore, it also includes a snap-fit ​​mechanism, which includes a first snap-fit ​​rotatably disposed on the first slide and a second snap-fit ​​disposed on the second slide that can snap-fit ​​with the first snap-fit. When the lifting component is in the first lifting state, the first buckle and the second buckle engage to lock the lifting component. To switch from the first lifting state to the second lifting state, the first buckle is rotated to separate the first buckle from the second buckle, releasing the lifting component so that it can switch from the first lifting state to the second lifting state, thereby driving the cover to move up and down relative to the body.

[0007] Furthermore, the locking mechanism also includes a torsion spring that is connected to the first buckle in a transmission manner. One end of the first buckle is provided with a hook that can engage with the second buckle, and the other end abuts against the torsion spring. When the lifting assembly is in the first lifting state, the first buckle engages with the second buckle under the elastic force of the torsion spring. If the first lifting state is to be switched to the second lifting state, the elastic force of the torsion spring is overcome to make the first buckle rotate, and the first buckle separates from the second buckle.

[0008] Furthermore, the locking mechanism also includes a pressure rod, one end of which is connected to the first buckle in a transmission manner, and the other end of which extends upward through the cover. By pressing the pressure rod, the first buckle can be rotated to release the lifting assembly.

[0009] Furthermore, the lifting assembly also includes a limiting mechanism, which includes a drive shaft, a limiting block, and a limiting guide rail cover. The drive shaft is rotatably mounted on the sliding end of the first support arm and is rolledly connected to the second slide groove. The limiting block is located on the side of the second slide away from the first support arm and is drivenly connected to the drive shaft. When the lifting assembly performs lifting movements, the drive shaft is rolledly connected to the second slide groove and drives the limiting block to rotate. The limiting guide rail cover is located on the side of the limiting block away from the second slide and is connected to the second slide. The limiting guide rail cover is provided with a first slot and a second slot. The limiting block can abut / separate from the first slot and the second slot respectively to fix or release the second lifting state of the lifting assembly.

[0010] Furthermore, the limiting block is provided with several limiting angles. When the limiting block moves to the first preset position and the second preset position, the limiting angles can respectively abut / separate from the first slot and the second slot, thereby fixing or releasing the second lifting state of the lifting assembly.

[0011] Furthermore, when the lifting assembly is in the first lifting state, the limiting block is stationary inside the limiting guide rail cover; During the transition from the first lifting state to the second lifting state, the cover is pulled up, and the limiting angle abuts against the limiting guide rail cover, restricting the rotation of the limiting block. This causes the limiting block to slide to the left along the setting direction of the limiting guide rail cover. When the limiting block moves to the first preset position, it can rotate counterclockwise. When the limiting angle abuts against the second slot, the limiting block stops rotating. The cover is then pulled up further, causing the limiting block to slide to the left until the lifting assembly reaches its highest height. At this point, the angle between the limiting block and the limiting guide rail cover is [value missing]. Pressing down the cover causes the limiting block to rotate clockwise until the limiting angle abuts against the first slot, thus fixing the lifting assembly in the second lifting state. At this time, the angle between the limiting block and the limiting guide rail cover is [value missing]. ; During the transition from the second lifting state to the first lifting state, the cover is pulled up. At this time, the limiting angle abuts against the limiting guide rail cover, forcing the limiting block to slide to the left. When the limiting block moves to the second preset position, the limiting block can rotate counterclockwise and the limiting angle abuts against the second slot. At this time, the angle between the limiting block and the limiting guide rail cover is... Press down the cover to cause the limiting block to rotate clockwise, switching to the first lifting state.

[0012] Furthermore, the aforementioned > The limiting block is locked in one direction by means of an angle difference.

[0013] Furthermore, the number of lifting components is at least two, and the two lifting components are arranged opposite to each other.

[0014] Furthermore, the present invention also provides a method for raising and lowering an electronic toilet seat, applicable to the liftable electronic toilet seat as described in any one of claims 1-9, wherein the raising and lowering method includes: Switching from the first lifting state to the second lifting state: By pulling up the cover, the angle between the first support arm and the second support arm is increased, thereby causing the cover to rise relative to the body. Switching from the second lifting state to the first lifting state: By pressing down the cover, the angle between the hinged intersection of the first support arm and the second support arm is reduced, thereby causing the cover to descend relative to the main body.

[0015] Based on the above, the liftable electronic toilet and lifting method provided by the present invention, compared with the prior art, by designing a lifting component that can switch between a first lifting state and a second lifting state, thereby driving the lid to lift and lower, which is convenient for users to clean and maintain. At the same time, the lifting component adopts a simple and compact pure mechanical structure, with a simple overall structure and no need for a complicated circuit system, which reduces the failure rate and maintenance cost, and also makes it convenient for users to wash and disinfect with water to thoroughly remove dirt and grime.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more. Additionally, the term "comprising" and any variations thereof mean "at least including."

[0021] Example 1 To address the technical problem of dirt and grime accumulating in the gap between the fixed part and the body of conventional electronic toilet seats, or to achieve at least one or more of the aforementioned advantages, an embodiment of the present invention provides a height-adjustable electronic toilet seat. For example... Figure 1 , Figure 2 As shown, the liftable electronic toilet includes a body 100, a cover 200, and a lifting assembly 300.

[0022] The body 100 serves as the basic supporting component of the electronic toilet, providing the basic installation space for the lid 200 and the lifting assembly 300, and forming a toilet bowl to accommodate excrement. The inner curvature of the toilet bowl is optimized for hydrodynamics to reduce stain residue. Specifically, the body 100 can be made of materials such as ceramic, artificial marble, fiberglass, or cast iron enamel. This embodiment uses a ceramic body 100 as an example, which is made by high-temperature ceramic firing and has a surface treated with a nano self-cleaning glaze (water absorption rate <0.5%), possessing good chemical stability, high hardness, and easy cleaning properties.

[0023] Preferably, the main body 100 may be provided with a mounting surface for fixing the cover 200 and the lifting assembly 300.

[0024] The cover 200 is mounted on the body 100 and can move up and down relative to the body 100 by switching between the first lifting state and the second lifting state via the lifting component 300, making it convenient for users to clean and disinfect the gaps and hard-to-clean corners between the cover and the body 100.

[0025] In practice, the cover 200 can be designed as a split unit, including a rear cover 210 and an upper cover 220. The rear cover 210 can be made of composite materials such as PP+ABS, which have high strength and aging resistance. Its bottom is fixed to the lifting assembly 300, serving as the direct carrier for lifting movement.

[0026] The top cover 220 can be made of antibacterial PP (with added silver ion antibacterial agent) and other materials, which can effectively inhibit the growth of microorganisms. The top cover 220 can be hinged to the back cover 210 through a hinge structure or a damping hinge, forming a structure that can be freely flipped like a toilet seat cover (opening angle 0°-98°) to meet daily opening and closing needs.

[0027] Preferably, the cover 20 also includes a seat ring 230. The seat ring 230 can be made of the same antibacterial PP (with added silver ion antibacterial agent) material as the top cover 220, which can effectively inhibit the growth of microorganisms. The seat ring 230 can be hinged to the rear cover 210 via a hinge structure or a damping hinge, allowing for independent flipping and opening. More preferably, a heating component (not shown) can be designed into the seat ring 230 to provide a heating function and improve the user experience.

[0028] When the lifting component 300 switches between the first lifting state and the second lifting state, it drives the rear cover 210 to lift and lower, and simultaneously drives the upper cover 220 and the seat ring 230 to lift and lower. This not only retains the traditional toilet seat usage habits, but also makes it convenient for users to clean and disinfect the gaps and hard-to-clean corners between the cover 200 and the main body 100.

[0029] like Figure 3 , Figure 4 As shown, the lifting assembly 300 can switch between a first lifting state (closed use state where the cover 200 is attached to the body 100) and a second lifting state (lifted state where the cover 200 is raised). The lifting assembly 300 adopts a purely mechanical structure, eliminating the need for complex circuits and electrical control lines. It has a simple and compact structure, is easy to maintain, and reduces costs.

[0030] In specific implementation, the lifting assembly 300 includes a first slide 310 disposed on the cover 200, a second slide 320 disposed on the body 100, and a first support arm 330 and a second support arm 340 that are hinged to each other between the first slide 310 and the second slide 320.

[0031] The first slide block 310 and the second slide block 320 are arranged opposite to each other and are respectively fixed to the cover 200 and the body 100 by bolts. The first slide block 310 and the second slide block 320 can be elongated metal plates, preferably made of stainless steel, which has good corrosion resistance. The first slide block 310 has an elongated first groove 311 designed along its setting direction. The second slide block 320 has an elongated second groove 321 designed along its setting direction. Preferably, the inner walls of the first groove 311 and the second groove 321 are smoothed to reduce friction.

[0032] The first support arm 330 and the second support arm 340 are cross-hinged at the middle by a pin to form a scissor fulcrum, allowing rotation between the first support arm 330 and the second support arm 340. Preferably, both the first support arm 330 and the second support arm 340 are made of high-strength, corrosion-resistant materials such as aluminum alloy or stainless steel.

[0033] Specifically, the hinged end of the first support arm 330 is hinged to the first slide block 310, and the sliding end of the first support arm 330 is slidably connected to the second slide groove 321. The hinged end of the second support arm 340 is hinged to the second slide block 320, and the sliding end of the second support arm 340 is slidably connected to the first slide groove 311.

[0034] When switching between lifting and lowering states, the sliding ends of the first support arm 330 and the second support arm 340 are displaced in the same direction along the setting directions of the second slide groove 321 and the first slide groove 311, respectively. The distance between the first slide block 310 and the second slide block 320 is changed by increasing or decreasing the angle of the hinge between the first support arm 330 and the second support arm 340, thereby driving the cover 200 to move up and down relative to the body 100.

[0035] For example, when the cross angle increases from 30° to 120°, it causes the cover 200 to rise. When the cross angle decreases from 120° to 30°, it causes the cover 200 to fall.

[0036] In some preferred embodiments, the lifting assembly 300 further includes a locking mechanism 350. The locking mechanism 350 is used to lock the lifting assembly 300 when it is in the first lifting state to prevent it from rising accidentally during use.

[0037] In practice, the latching mechanism 350 includes a first latch 351, a torsion spring 352, and a second latch 353.

[0038] The first latch 351 can be an L-shaped plastic part, such as POM material, with self-lubricating properties. The first latch 351 is rotatably mounted on the first slide 310 via a pin, and one end of it has a hook that can engage with the second latch 353, while the other end abuts against the torsion spring 352. The torsion spring 352 can apply a spring force to the first latch 351.

[0039] The second latch 353 can be a plastic boss fixed to the second slide 320 and extending towards the first slide 310, with a slot on it that matches the hook on the first latch 351. Of course, as... Figure 4 As shown, the second buckle 353 can also be integrally formed with the second slide 320.

[0040] Taking the illustration as an example, when the lifting assembly 300 is in the first lifting state, the first latch 351 engages with the second latch 353 under the elastic force of the torsion spring 352, achieving mechanical locking to secure the lifting assembly 300. To switch from the first lifting state to the second lifting state, press the first latch 351 to overcome the elastic force of the torsion spring 352, causing the first latch 351 to rotate clockwise, separating the first latch 351 from the second latch 353, releasing the lifting assembly 300, so that the lifting assembly 300 can switch from the first lifting state to the second lifting state, thereby driving the cover 200 to move up and down relative to the body 100.

[0041] Furthermore, the latching mechanism 350 also includes a pressure rod 354. One end of the pressure rod 354 is connected to the first latch 351, and the other end of the pressure rod 354 extends upward through the rear cover 210 and forms a protrusion, allowing the user to rotate the first latch 351 by pressing the pressure rod 354 to release the lifting assembly 300. The pressure rod 354 can be made of plastic or metal, and this application does not impose any restrictions on this.

[0042] Preferably, the end of the pressure rod 354 furthest from the first latch 351 may also be provided with a pressure rod cap (not shown). The diameter of the pressure rod cap is larger than the diameter of the pressure rod 354 to improve dustproof and dirt-proof performance. The pressure rod cap can be a conventional silicone round cap, which can be designed separately from the pressure rod 354, or it can be integrally molded with the pressure rod 354, both of which are within the scope of protection of this application.

[0043] Please combine Figure 3 , 4 See Figures 5-9 In some preferred embodiments, the lifting assembly 300 further includes a limiting mechanism 360. The limiting mechanism 360 is used to lock the lifting assembly 300 when it is in the second lifting state to prevent the cover 200 from falling.

[0044] The limiting mechanism 360 includes a drive shaft 361, a limiting block 362, and a limiting guide rail cover 363. The drive shaft 361 is rotatably mounted on the sliding end of the first support arm 330 and is rollably connected to the second slide groove 321. When the sliding end of the first support arm 330 moves along the second slide groove 321, it can drive the drive shaft 361 to roll synchronously.

[0045] The limiting block 362 is located on the side of the second slide block 320 away from the first support arm 330 and is connected to the drive shaft 361, rotating synchronously with the drive shaft 361. The edge of the limiting block 362 is provided with several limiting angles 3621. The limiting guide cover 363 is located on the side of the limiting block 362 away from the second slide block 320 and is connected to the second slide block 320. The limiting guide cover 363 is a concave cover, allowing the limiting block 362 to move within the limiting guide cover 363. Specifically, the limiting guide cover 363 is provided with a first slot 3631 and a second slot 3632. When the limiting block 362 moves to the first preset position or the second preset position, the limiting angles 3621 can abut / separate with the first slot 3631 and the second slot 3632 respectively, forming an angle difference. This angle difference enables unidirectional rotation locking, used to fix or release the lifting assembly to maintain the second lifting state.

[0046] by Figures 5-9 For example, this embodiment uses four limiting angles 3621, including a first limiting angle 3621A, a second limiting angle 3621B, a third limiting angle 3621C, and a fourth limiting angle 3621D, to specifically illustrate the process of the lifting assembly 300 switching between the first lifting state and the second lifting state: like Figure 5 As shown, when the lifting assembly is in the first lifting state, the limit block 362 is stationary inside the limit guide rail cover 363. like Figures 6-7 As shown, the first lifting state switches to the second lifting state: 1. Press the lever 354 to unlock the locking mechanism 350 to release the lifting assembly 300; 2. Pull up the cover 200 to move the limiting block 362 to the left. Before it moves to the first preset position, the first limiting angle 3621A abuts against the limiting guide rail cover 363, restricting the rotation of the limiting block 362 and allowing it to slide only to the left. When the limiting block 362 moves to the first preset position (the second limiting angle 3621B aligns with the first slot 3631), the limiting block 362 can rotate counterclockwise. When the first limiting angle 3621A abuts against the second slot 3632, the limiting block 362 stops rotating. Continue pulling up the cover 200 to slide the limiting block 362 to the left until the lifting assembly 300 reaches its highest height. At this time, the angle between the limiting block 362 and the limiting guide rail cover is... ; 3. Press down the cover 200, causing the limiting block 362 to rotate clockwise until the fourth limiting angle 3621D engages with the first slot 3631 and the first limiting angle 3621A abuts against the limiting guide rail cover 363. These actions lock the lifting assembly 300 in its second lifting state. At this point, the angle between the limiting block 362 and the limiting guide rail cover is... .

[0047] like Figures 8-9 As shown, the second lifting state switches to the first lifting state: 1. Pull up the cover 200 to move the limiting block 362 to the left. Before moving to the second preset position, the first limiting angle 3621A abuts against the limiting guide rail cover 363, restricting the limiting block 362 from rotating and allowing it to slide only to the left. When the limiting block 362 moves to the second preset position (the first limiting angle 3621A aligns with the first slot 3631), the limiting block 362 can rotate counterclockwise until the fourth limiting angle 3621D abuts against the second slot 3632. At this time, the lifting assembly 300 is at its highest height, and the angle between the limiting block 362 and the limiting guide rail cover is... ; 2. Press down the cover 200 to make the limiting block 362 rotate clockwise and move to the right. When the third limiting angle 3621C passes the first slot 3631, it abuts against the limiting guide cover 363 to restrict the rotation of the limiting block 362. Continue to press down the cover 200 to make the limiting block 362 slide to the right until the lifting assembly 300 returns to the first lifting state. The locking mechanism 350 locks the lifting assembly 300 to keep the lifting assembly 300 in the first lifting state.

[0048] Preferably, > In this embodiment, the unidirectional rotation locking of the limiting block 362 is achieved through the angle difference. It can be 55°, It can be 77°, It can be 125°. Of course, the specific angle can be adjusted according to the design size and position of the first slot 3631 and the second slot 3632 on the actual limit block 362 and the limit guide cover 363, as long as unidirectional rotation locking can be achieved, all of which are within the protection scope of this application.

[0049] In some preferred embodiments, the number of lifting components 300 is at least two. The two lifting components are arranged opposite to each other and can synchronously drive the cover 200 to lift the body 100 at the bottom, so as to avoid the problem of the cover 200 tilting or becoming unstable due to unilateral force.

[0050] Example 2 An embodiment of the present invention also provides a method for raising and lowering an electronic toilet seat, applied to the aforementioned liftable electronic toilet seat to switch between a first raising and lowering state and a second raising and lowering state. For details regarding the functions and effects of the liftable electronic toilet seat, please refer to the foregoing Embodiment 1, which will not be repeated here.

[0051] Preferably, the electronic toilet also has conventional cleaning functions such as bidet and feminine wash, as well as intelligent functions such as drying. At the same time, the lifting component 300 can be intelligently linked with the cleaning and drying functions through an intelligent control module (conventional technology). For example, when the lid 200 rises, the heating, cleaning, and drying functions are automatically turned off, and the functions are automatically restored after the lid 200 returns to its original position.

[0052] In summary, the liftable electronic toilet and lifting method provided by this invention, compared with the prior art, by designing a lifting component that can switch between a first lifting state and a second lifting state, thereby driving the lid to lift and lower, makes it convenient for users to clean and maintain. At the same time, the lifting component adopts a simple and compact pure mechanical structure, with a simple overall structure and no need for a complicated circuit system, reducing the failure rate and maintenance costs, and also making it convenient for users to wash and disinfect, thoroughly removing dirt and grime.

[0053] Although this document frequently uses terms such as body, cover, and lifting assembly, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of the invention; interpreting them as any additional limitation would contradict the spirit of the invention.

[0054] Furthermore, those skilled in the art should understand that although many problems exist in the prior art, each embodiment or technical solution of the present invention can be improved in only one or a few aspects, without necessarily solving all the technical problems listed in the prior art or the background art simultaneously. Those skilled in the art should understand that any content not mentioned in a claim should not be construed as a limitation on that claim.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.

The height-adjustable electronic toilet seat according to claim 1, characterized in that: It also includes a snap-fit ​​mechanism, which includes a first snap-fit ​​rotatably disposed on the first slide and a second snap-fit ​​disposed on the second slide that can snap-fit ​​with the first snap-fit. When the lifting component is in the first lifting state, the first buckle and the second buckle engage to lock the lifting component. To switch from the first lifting state to the second lifting state, the first buckle is rotated to separate the first buckle from the second buckle, releasing the lifting component so that it can switch from the first lifting state to the second lifting state, thereby driving the cover to move up and down relative to the body.

3. The height-adjustable electronic toilet seat according to claim 2, characterized in that: The latching mechanism further includes a torsion spring that is connected to the first latch in a transmission. One end of the first latch is provided with a hook that can latch with the second latch, and the other end abuts against the torsion spring. When the lifting assembly is in the first lifting state, the first latch latches with the second latch under the elastic force of the torsion spring. If the first lifting state is to be switched to the second lifting state, the elastic force of the torsion spring is overcome to make the first latch rotate, and the first latch separates from the second latch.

4. The height-adjustable electronic toilet seat according to claim 3, characterized in that: The locking mechanism also includes a pressure rod, one end of which is connected to the first buckle, and the other end of which extends upward through the cover. By pressing the pressure rod, the first buckle can be rotated to release the lifting assembly.

5. The height-adjustable electronic toilet according to any one of claims 1-4, characterized in that: The limiting mechanism also includes a drive shaft, which is rotatably mounted on the sliding end of the first support arm and is rolledly connected to the second slide groove. The drive shaft is drivenly connected to the limiting block. When the lifting assembly performs lifting movement, the drive shaft is rolledly connected to the second slide groove and drives the limiting block to rotate.

6. The height-adjustable electronic toilet according to claim 5, characterized in that: When the limiting block moves to the first preset position and the second preset position, the limiting angle can abut / separate from the first slot and the second slot respectively, thereby fixing or releasing the second lifting state of the lifting assembly.

7. The height-adjustable electronic toilet according to any one of claims 1-4, characterized in that: The number of lifting components is at least two, and the two lifting components are arranged opposite to each other.

8. A method for raising and lowering an electronic toilet seat, characterized in that: Applied to the liftable electronic toilet as described in any one of claims 1-7, the lifting method includes: Switching from the first lifting state to the second lifting state: By pulling up the cover, the angle between the first support arm and the second support arm is increased, thereby causing the cover to rise relative to the body. Switching from the second lifting state to the first lifting state: By pressing down the cover, the angle between the hinged intersection of the first support arm and the second support arm is reduced, thereby causing the cover to descend relative to the main body.
