Description

Technical Field

[0001] This invention relates to the field of flush toilets, and more specifically to a toilet seat that can automatically stand upright after a delayed release of its adhesive properties. Background Technology

[0002] Currently, existing toilet seats are quite limited in terms of convenience and hygiene. Because after using the toilet, the seat is always placed horizontally on the toilet without human intervention, if the user forgets or is not used to lifting the seat, it is likely to be frequently contaminated by urine and sewage. If the seat is lifted quickly, it is easy for it to collide with the lid or tank, generating noise and causing a lot of trouble for people in actual use.

[0003] Most commercial public restrooms on the market use rotating toilet seats that require manual opening to prevent soiling during urination. Furthermore, most rotating toilet seats on the market lack a soft-close mechanism, resulting in loud noise when the seat collides with the ceramic surface, negatively impacting the user experience.

[0004] In response to the products currently on the market, our company has developed a toilet seat with a delayed automatic uprighting function and a slow-rise feature.

[0005] Therefore, this invention addresses the aforementioned problems. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a toilet seat that can automatically stand upright after a delayed release of adsorption.

[0007] This invention is achieved through the following technical solution: A toilet seat ring capable of delayed release of adsorption and automatic uprighting includes a rotating seat ring 1 rotatably connected to a toilet seat 100, a rotating bushing 2 with an internal hydraulic hinge 10 fixed at one end of the rotating seat ring 1, and a delayed release of adsorption and automatic uprighting control device 3 on the rotating seat ring 1 that enables the rotating seat ring 1 to automatically stand up relative to the toilet after a delay. The delayed release of adsorption and automatic uprighting control device 3 includes a suction cup assembly 4 and a hinge drive assembly 5 disposed on the rotating seat ring 1. The suction cup assembly 4 includes a rigid mounting bracket 41 fixed to the bottom of one side of the rotating seat ring 1. A suction cup body 42 that can cooperate with the contact surface of the toilet seat 100 to form a sealed space is detachably fixed on the rigid mounting bracket 41. The suction cup body 42 includes a suction cup connecting part 421 connected to the inner wall of the rigid mounting bracket 41 and an adsorption part 422 connected to the lower end of the suction cup connecting part 421. A deformable top plate 423 is provided on the top of the suction cup connecting part 421. An elastic ventilation slit 420 is provided on the deformable top plate 423 to connect the interior of the suction cup body 42 with the air guide channel 410. The hinge drive assembly 5 includes fixed rotating arms 51 fixed on both sides of the toilet seat 100. A transverse support shaft 52 is fixedly connected to the rotating shaft core of the hydraulic hinge 10 on the fixed rotating arms 51. A drive torsion spring 53 is provided on the transverse support shaft 52. One end of the drive torsion spring 53 is a fixed end, which is fixed on the fixed rotating arms 51, and the other end of the drive torsion spring 53 is a drive end, which is fixed on the inner wall of the rotating bushing 2. When the rotating seat ring 1 is not under pressure, the outside air will slowly enter the adsorption part 422 through the air guide channel 410 of the suction cup assembly 4 from the elastic ventilation cut 420, so that the adsorption force between the adsorption part 422 and the toilet seat gradually decreases until the rotational elastic force of the drive torsion spring 53 of the hinge drive assembly 5 is greater than the adsorption force of the adsorption part, at which point the drive torsion spring 53 will drive the rotating seat ring 1 to open automatically upward.

[0011] A further preferred embodiment of the present invention is as follows: the quick-release buckle 62 or the central fixing sleeve 412 is provided with a strip-shaped through hole / groove 621 to facilitate the corresponding deformation of the quick-release buckle 62.

[0012] A further preferred embodiment of the present invention is as follows: the rigid mounting bracket 41 is provided on one side of the suction cup body 42, and a protective pad 45 is provided that can abut against the contact surface when the suction cup body 42 is engaged with the contact surface.

[0013] A further preferred embodiment of the present invention is as follows: a plurality of spaced connecting ribs 413 are connected between the outer mounting ring 411 and the central fixing sleeve 412, and a plurality of spaced air channels 410 communicating with the outside atmosphere are formed between the plurality of connecting ribs 413.

[0014] A further preferred embodiment of the present invention is as follows: a suction cup mounting groove for mounting the suction cup assembly 4 is provided at the bottom of the rotating seat ring 1; the outer wall of the outer mounting ring 411 is clamped to the inner wall of the suction cup mounting groove; the top of the outer mounting ring 411 is clamped to the bottom of the suction cup mounting groove; the height of the top of the outer mounting ring 411 is higher than the height of the top of the central fixing sleeve 412; a ventilation gap is left between the top of the central fixing sleeve 412 and the bottom of the suction cup mounting groove; and the elastic ventilation vent 420 communicates with the air guide channel 410 through the ventilation gap when it is opened and closed.

[0015] A further preferred embodiment of the present invention is as follows: a transverse groove 511 is provided on the fixed rotating arm 51, and the fixed end of the driving torsion spring 53 is inserted into the transverse groove so that the driving torsion spring 53 is positioned on the fixed rotating arm 51. A driving groove 201 is provided on the inner wall of the rotating bushing 2, and the driving end of the driving torsion spring 53 is inserted into the driving groove so that the driving torsion spring 53 drives the rotating bushing 2 to rotate relative to the fixed rotating arm 51 under its own elastic force.

[0016] A further preferred embodiment of the present invention is as follows: a fixing block 101 is provided on the outer wall of one end of the hydraulic hinge 10; a positioning groove 202 for locking the fixing block 101 is provided in the rotating bushing 2; a locking hole 203 is provided on the outer wall of the rotating bushing 2; an annular sliding groove 521 is provided on the transverse support shaft 52 at a position opposite to the locking hole 203; and a snap-fit ​​member 7 is installed in the locking hole 203, which can pass through the rotating bushing 2 and lock onto one side wall of the annular sliding groove 521 and slide along the annular sliding groove 521.

[0017] Compared with the prior art, the present invention has the following advantages: 1. When the rotating seat is not under pressure, the outside atmosphere will slowly enter the suction part through the air guide channel of the suction cup assembly from the elastic vent, so that the suction force between the suction part and the toilet seat gradually decreases. When the rotational elastic force of the drive torsion spring of the hinge drive assembly is greater than the suction force of the suction part, the drive torsion spring will drive the rotating seat to open automatically upward, slowly opening until it is upright. The product is quiet and hygienic during use.

[0018] 2. The suction cup assembly automatically releases its suction at the designated time, and the hinge drive assembly on the toilet seat acts as an automatic flipping mechanism. When the user presses down and rotates the seat, it adheres to the toilet seat via the suction cup assembly. When the user finishes using the toilet, the suction cup assembly automatically releases its suction after a delay, and the seat rotates to automatically flip back to its original position, achieving fully automatic operation.

[0019] 3. When the seat ring is rotated and subjected to pressure, as the suction cup body moves towards the contact surface, the volume of the inner cavity of the suction cup body gradually decreases, creating a pressure difference between the internal and external air pressures. This pressure difference causes the deformation component to deform accordingly, transforming the elastic vent into a vent that connects the inner cavity of the suction cup body to the outside. Gas from the inner cavity of the suction cup body is then blown out through the elastic vent, facilitating the movement of the suction cup body towards the contact surface. When the gas in the inner cavity of the suction cup body is completely expelled, the elastic vent, under the deformation and reset force of the deformation component, becomes a vent that isolates the inner cavity of the suction cup body from the outside, ensuring a sealed state between the suction cup body and the toilet seat contact surface. This guarantees a firm and reliable adhesion between the suction cup body and the toilet seat contact surface, improving adhesion efficiency.

[0020] 4. For easy disassembly and assembly, a snap-fit ​​structure is provided between the outer wall of the mounting part and the inner wall of the suction cup connection part.

[0021] 5. To prevent the suction cup from being damaged by excessive pressure, the mounting bracket is equipped with a protective pad on one side of the suction cup body, which can abut against the contact surface when the suction cup body mates with the contact surface.

[0049] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0050] like Figure 1-27 As shown, this invention discloses a toilet seat ring capable of delayed release of suction and automatic uprighting, comprising a rotating seat ring 1 rotatably connected to a toilet seat 100, a rotating bushing 2 with an internal hydraulic hinge 10 fixed to one end of the rotating seat ring 1, and a delayed release of suction and automatic uprighting control device 3 on the rotating seat ring 1, enabling the rotating seat ring 1 to automatically rise relative to the toilet seat after a delay. The delayed release of suction and automatic uprighting control device 3 includes a suction cup assembly 4 for delayed release of suction and a hinge drive assembly 5 for driving the rotating seat ring 1 to rotate and rise relative to the toilet seat 100, both mounted on the rotating seat ring 1. The rotating seat ring as a whole is composed of two main parts: the "suction cup assembly" and the "hinge drive assembly" (e.g., ...). Figure 1-7 As shown). The "suction cup assembly" consists of multiple parts (such as... Figure 20-27 As shown, the "suction cup assembly" and "hinge drive assembly" are detachable from the rotating seat and are fixed to the rotating seat to form a single product.

[0051] See Figure 18-27 The suction cup assembly 4 includes a rigid mounting bracket 41 fixed to the bottom of one side of the rotating seat ring 1. A suction cup body 42 that can cooperate with the contact surface of the toilet seat 100 to form a sealed space is detachably fixed on the rigid mounting bracket 41. The suction cup body 42 includes a suction cup connecting part 421 connected to the inner wall of the rigid mounting bracket 41 and an adsorption part 422 connected to the lower end of the suction cup connecting part 421. A deformable top plate 423 is provided on the top of the suction cup connecting part 421. An elastic ventilation cut 420 is provided on the deformable top plate 423 to connect the interior of the suction cup body 42 with the air guide channel 410. See Figure 5-15 The hinge drive assembly 5 includes fixed rotating arms 51 fixed on both sides of the toilet seat 100. A transverse support shaft 52 is fixedly connected to the rotating shaft core of the hydraulic hinge 10 on the fixed rotating arms 51. A drive torsion spring 53 is provided on the transverse support shaft 52. One end of the drive torsion spring 53 is a fixed end, which is fixed on the fixed rotating arms 51, and the other end of the drive torsion spring 53 is a drive end, which is fixed on the inner wall of the rotating bushing 2. When the rotating seat ring 1 is not under pressure, the outside air will slowly enter the adsorption part 422 through the air guide channel 410 of the suction cup assembly 4 from the elastic ventilation cut 420, so that the adsorption force between the adsorption part 422 and the toilet seat gradually decreases until the rotational elastic force of the drive torsion spring 53 of the hinge drive assembly 5 is greater than the adsorption force of the adsorption part, at which point the drive torsion spring 53 will drive the rotating seat ring 1 to open automatically upward.

[0052] See Figure 18-27 In order to effectively improve the structure of the suction cup assembly and enhance both the suction capacity and the slow release of suction, an innovative design was made for the suction cup assembly. The specific structure is as follows: An integrally formed outer mounting ring 411 and a central fixing sleeve 412 are provided on the rigid mounting bracket 41. The air guide channel 410 is provided between the outer mounting ring 411 and the central fixing sleeve 412. The suction cup body 42 is installed inside the central fixing sleeve 412. The suction cup connecting part 421 of the suction cup body 42 is clamped to the inner wall of the central fixing sleeve 412.

[0053] See Figure 18-26 In order to facilitate control and achieve the effect of delaying time and effectively controlling the opening and closing of the elastic ventilation slit, the position design of the deformation plate of the suction cup body is specifically developed. The specific implementation plan is as follows: The suction cup assembly 4 also includes a deformation tube 43 for supporting the suction cup connection part 421. The deformation top plate 423 is set on the top of the deformation tube 43. An annular snap-fit ​​groove 431 is provided on the outer wall of the deformation tube 43, and a snap-fit ​​protrusion 44 is provided on the inner wall of the suction cup connection part 421 to snap-fit ​​with the annular snap-fit ​​groove 431.

[0054] Implementation plan two is: See Figure 27 The difference from the first implementation scheme is that no deformation fitting is provided; instead, the deformation top plate 423 is directly set on the top of the suction cup connection part 421 of the suction cup body 42. That is, the deformation top plate 423 and the suction cup connection part 421 are integrally formed.

[0055] See Figure 20-26To facilitate quick installation and removal of the suction cup body 42, a quick-installation structure is designed. Specifically, a quick-installation structure 6 is provided between the suction cup body 42 and the central fixing sleeve 412 for quickly mounting the suction cup body 42 onto the rigid mounting bracket 41. The quick-installation structure 6 includes a quick-installation protruding ring 61 on the outer wall of the suction cup connecting part 421 and a quick-installation buckle 62 on the central fixing sleeve 412 that engages with the quick-installation protruding ring 61. When the suction cup body is aligned with the central fixing sleeve 412 and pushed upwards, the quick-installation protruding ring 61 on the outer wall of the suction cup connecting part 421 contacts the quick-installation buckle 62, causing the buckle 62 to deform and move outwards. After the suction cup connecting part 421 is in position, the quick-installation buckle 62 returns to its original position, locking the quick-installation protruding ring 61 in place. This allows for quick installation of the suction cup body onto the central fixing sleeve. The quick-release buckle 62 or the central fixing sleeve 412 is provided with a strip-shaped through hole / groove 621 to facilitate the deformation of the quick-release buckle 62.

[0056] See Figure 26 To prevent the suction cup from being damaged by excessive pressure, the rigid mounting bracket 41 has a protective pad 45 on one side of the suction cup body 42, which can abut against the contact surface when the suction cup body 42 mates with the contact surface. The protective pad 10 can be made of materials such as plastic, silicone, or rubber. In some embodiments, the protective pad 10 can be formed onto the mounting bracket 1 using an elastomeric material through secondary injection molding, or it can be adhered to the mounting bracket 1 using a foam-type elastic pad with adhesive backing.

[0057] See Figure 23 A number of spaced connecting ribs 413 are connected between the outer mounting ring 411 and the central fixing sleeve 412, and a number of spaced air channels 410 that are connected to the outside atmosphere are formed between the connecting ribs 413.

[0058] See Figure 18-19 A suction cup mounting groove for mounting the suction cup assembly 4 is provided at the bottom of the rotating seat ring 1. The outer wall of the outer mounting ring 411 is locked with the inner wall of the suction cup mounting groove. The top of the outer mounting ring 411 is locked at the bottom of the suction cup mounting groove. The height of the top of the outer mounting ring 411 is higher than the height of the top of the central fixing sleeve 412. A ventilation gap is left between the top of the central fixing sleeve 412 and the bottom of the suction cup mounting groove. When the elastic ventilation slit 420 is opened and closed, it communicates with the air guide channel 410 through the ventilation gap.

[0059] See Figure 13A transverse slot 511 is provided on the fixed rotating arm 51. The fixed end of the driving torsion spring 53 is inserted into the transverse slot, so that the driving torsion spring 53 is positioned on the fixed rotating arm 51. A driving slot 201 is provided on the inner wall of the rotating bushing 2. The driving end of the driving torsion spring 53 is inserted into the driving slot, so that the driving torsion spring 53 drives the rotating bushing 2 to rotate relative to the fixed rotating arm 51 under its own elastic force.

[0060] See Figure 13-17 The hydraulic hinge 10 has a fixing block 101 on the outer wall of one end. A positioning groove 202 for locking the fixing block 101 is provided inside the rotating bushing 2. A locking hole 203 is provided on the outer wall of the rotating bushing 2. An annular sliding groove 521 is provided on the transverse support shaft 52 opposite to the locking hole 203. A locking member 7 is installed in the locking hole 203, which can pass through the rotating bushing 2 and lock onto one side wall of the annular sliding groove 521 and slide along the annular sliding groove 521. The locking member 7 is sheet-shaped, but can also be designed as a block, column, or other shapes. Two elastic hooks 71 are provided at the bottom of the snap-fit ​​component 7, and a guide slope 72 is provided at the top of the elastic hooks 71. The snap-fit ​​component 7 is used to connect the fixed rotating arm 51 and the rotating bushing 2 as a whole. During assembly, the hydraulic hinge 10 is first installed in the rotating bushing 1 by engaging the fixed locking block 101 and the positioning slot 202. The engagement of the fixed locking block 101 and the positioning slot 202 is to enable the hydraulic hinge to rotate synchronously with the rotating bushing 1. Then, the transverse support shaft 52 of the fixed rotating arm 51 is inserted into the rotating bushing 2, so that the square end of the transverse support shaft 52... The groove engages with the square end of the shaft core of the hydraulic hinge 10. When the transverse support shaft 52 is installed in the transverse position, the engaging member 7 is inserted into the locking hole 203. The two elastic hooks 71 are compressed by the wall of the locking hole 203 and undergo elastic deformation. The guide slope 72 facilitates the smooth insertion of the engaging member 7 along the locking hole 203. When the engaging member is inserted in the position, the elastic hooks 71 are reset and locked on the inner edge of the locking hole 203. The part of the elastic hooks 71 protruding from the locking hole 203 is just inserted into the annular sliding groove 521 of the transverse support shaft 52. In this way, the fixed rotating arm is installed on the rotating bushing 2. To better and more stably install the snap-fit ​​component 7 into the snap-fit ​​hole 203, an annular snap-fit ​​edge 73 with a width greater than the width of other parts of the snap-fit ​​component 7 is provided on the top of the snap-fit ​​component 7. An annular snap-fit ​​platform is provided inside the snap-fit ​​hole 203 to engage with the annular snap-fit ​​edge. In this way, when the snap-fit ​​component 7 is installed in the snap-fit ​​hole 203, the elastic snap hook 71 and the annular snap-fit ​​platform 73 respectively engage with the inner edge of the snap-fit ​​hole 203 and the annular snap-fit ​​platform, so that both ends of the snap-fit ​​component 7 engage with the snap-fit ​​hole 203, making the installation of the transverse support shaft 52 and the rotating bushing 2 more stable and less likely to detach.

[0061] Since the hydraulic hinge's shaft is fixed to the transverse support shaft 52 of the fixed rotating arm 51, when the driving end of the driving torsion spring 53 drives the rotating sleeve 2, the rotating sleeve 2 can drive the hydraulic hinge 10 and the snap-fit ​​7 to rotate synchronously relative to the toilet seat and the fixed rotating arm 51. The snap-fit ​​7 rotates circumferentially within the annular sliding groove 521. Therefore, by cooperating with the annular sliding groove 521, the elastic hook 71 of the snap-fit ​​7 achieves two functions: first, it connects the transverse support shaft 52 of the fixed rotating arm 51 to the rotating sleeve 2; second, it enables the snap-fit ​​7 to rotate relative to the transverse support shaft 52.

[0062] The working principle of this invention is as follows: 1. When in use, after rotating the seat ring and pressing it down to adhere to the ceramic surface, the bottom "suction cup component" will adhere to the ceramic surface, maintaining a close fit. Compared to other rotating seat rings on the market that generally use ordinary rubber studs or soft rubber studs, which result in swaying and vibration during use and lack of stability, our rotating seat ring features suction cups and anti-slip rubber on the "suction cup component," providing a secure grip on the ceramic surface and ensuring superior stability and a more premium user experience.

[0063] 2. After use or when the seat ring is no longer under pressure, the air groove of the bottom "suction cup assembly" will slowly take in air. After a set time, the suction force of the suction cup will decrease or disappear and then release. Under the torsion force of the torsion spring in the "hinge assembly", the seat ring will automatically open upwards to a certain angle.

[0064] 3. After the seat ring rotates upwards and automatically opens to a certain angle, it continues to open slowly upwards until it is upright, thanks to the action of the damper. The product is quiet and hygienic during use.

[0065] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any modifications or variations made by those skilled in the art, without departing from the scope of the present invention, using the disclosed technical content, are equivalent embodiments of the present invention. Therefore, all equivalent changes made based on the concept of the present invention without departing from the scope of the present invention should be covered within the protection scope of the present invention.
