Description

Technical Field

[0001] This utility model belongs to the technical field of toilet seat technology, and in particular relates to a toilet seat with an automatically flip-up seat ring. Background Technology

[0002] Currently, most non-smart toilet seat products on the market only have a soft-close function, lacking a mechanism to automatically lift the seat after the user leaves. Since men usually urinate standing up while women usually sit down, women often do not lift the seat after using the toilet. If a male user subsequently urinates standing up without lifting the seat, urine leakage and contamination of the seat are very likely to occur, causing hygiene problems in unisex or male-only restrooms. Although smart toilet seats with automatic functions may exist as a solution, they rely on complex electronic structures, are expensive, and have high maintenance costs, making them neither necessary nor economically feasible for all users. Utility Model Content

[0003] (I) Purpose of the utility model

[0004] To overcome the above shortcomings, the purpose of this utility model is to provide a toilet seat that can automatically flip up the seat ring, so as to solve the technical problems of existing ordinary toilet seats where the seat ring does not flip up automatically, resulting in the seat ring being contaminated, and intelligent seats that rely on complex electronic structures to flip up automatically, which are expensive, have high maintenance costs, and poor economic applicability.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the technical solution provided in this application is as follows:

[0007] A toilet seat with an automatically flip-up seat ring includes: a hinge, a seat ring, a pivot rotatably mounted on the hinge and connected to the seat ring at both ends, with a pivot pressing part and a pivot hook on the pivot, a main shaft spring encircling the pivot and abutting the hinge and the pivot at both ends, which retracts when an external force causes the seat ring and the pivot to rotate downwards synchronously, and a drive cylinder and a storage cylinder disposed within the hinge and corresponding to the pivot pressing part and the pivot hook, respectively. The drive cylinder and the storage cylinder are interconnected, and their drive ends can both extend movably out of the upper surface of the hinge. When the pivot rotates forwards, the drive cylinder is squeezed by the pivot pressing part, expelling internal air. The gas is discharged into the storage cylinder, causing the drive end of the storage cylinder to move upward and engage the rotating shaft hook. The delayed exhaust valve, which is located inside the seat hinge and whose upper end can extend movably out of the seat hinge, is connected to the storage cylinder. When the seat ring rotates in the forward direction and contacts the upper end of the delayed exhaust valve, and the human body sits on the seat ring, the upper end of the delayed exhaust valve is driven downward by the seat ring and is continuously pressured to enter a sealed state. After the human body leaves the seat ring, the upper end of the delayed exhaust valve returns to its original position and discharges the gas in the storage cylinder, causing the drive end of the storage cylinder to descend and disengage from the rotating shaft hook. Under the elastic force of the main shaft spring, the rotating shaft and the seat ring rotate in the opposite direction and flip to a vertical state.

[0008] This application provides a fully mechanical automatic seat-flipping solution. When the user presses down on the seat, the rotating shaft pressing part squeezes the drive cylinder, releasing the internal gas into the storage cylinder. This causes the drive end of the storage cylinder to move upward and engage the rotating shaft hook, thereby locking the spring force of the main shaft spring that coils as the seat rotates downward. Simultaneously, the user sitting on the seat compresses the delayed exhaust valve, sealing it and preventing gas leakage. When the user leaves the seat, the delayed exhaust valve automatically resets and releases gas, the drive end of the storage cylinder descends and disengages from the hook, the main shaft spring releases its spring force, driving the rotating shaft to reverse, ultimately automatically flipping the seat to an upright position. This solution requires no electricity, reliably solving the hygiene problem caused by users forgetting to manually flip the seat, and is especially suitable for unisex restrooms, while retaining the user's freedom to manually operate the seat.

[0009] In some embodiments, the drive cylinder includes: a first base, a first connector disposed below the first base and communicating with the first base, a one-way exhaust valve disposed inside the first base and corresponding to the first connector, a first upper cover disposed above the first base and covering the first base, a first cylinder piston movably disposed in the first upper cover, and a first return spring disposed inside the first base and having its two ends respectively abutting against the first base and the first cylinder piston, which can be compressed when the rotating shaft pressing part squeezes the first cylinder piston downward, and drive the first cylinder piston upward to draw air after the rotating shaft pressing part disengages from the first cylinder piston;

[0010] The design of this drive cylinder ensures that compressed gas can only flow to the storage cylinder in one direction through a one-way exhaust valve, effectively preventing energy loss caused by gas backflow. When the piston is pressed down by the rotating shaft pressing part, it compresses the first return spring and discharges gas. When the external force is removed, the first return spring can automatically push the piston back to its original position, preparing for the next pressing operation to draw in air, ensuring the continuity and reliability of the action. The first seal (such as a leather cup) cooperates with the piston groove to provide good dynamic sealing, ensuring the airtightness and durability of the cylinder under frequent use.

[0011] In some embodiments, the gas storage cylinder includes: a second base, a second connector disposed below the second base and communicating with the drive cylinder and the time-delayed exhaust valve, a second upper cover disposed above the second base and covering the second base, a second cylinder piston movably disposed in the second upper cover with a second cylinder piston hook that engages with the rotating shaft hook at its upper end, and a second return spring disposed in the second base and with its two ends respectively abutting against the second upper cover and the second cylinder piston, which can be compressed when gas is input into the gas storage cylinder through the second connector to drive the second cylinder piston to move upward, and unfolded after the gas is discharged from the gas storage cylinder to drive the second cylinder piston to move downward;

[0012] This gas storage cylinder design, upon receiving compressed gas from the drive cylinder, pushes the piston of the second cylinder upward, causing the upper end of the second cylinder piston hook to firmly engage with the shaft hook, thereby reliably locking the elastic energy of the main shaft spring. The second return spring is compressed and stores energy when the piston moves upward. When the gas in the gas storage cylinder is discharged through the delayed exhaust valve, the spring can quickly unfold, pushing the second cylinder piston downward to reset, ensuring timely and reliable release of the lock on the shaft. The design of the second seal (such as V-shaped rubber) ensures the long-term sealing performance of the gas storage cylinder in the inflated state, preventing slow gas leakage from causing malfunctions.

[0013] In some embodiments, the time-delayed exhaust valve includes: a valve seat connected to a gas storage cylinder, a pressure relief hole in the middle, a sealing member movably disposed in the valve seat and extending out of the valve seat at the upper end, the sealing member corresponding to the pressure relief hole, and a third return spring disposed in the valve seat and abutting against the valve seat and the sealing member at both ends respectively, which can be compressed when the sealing member is pressed and moves downward to block the pressure relief hole, and unfold when the sealing member is unpressurized to drive the sealing member to move upward to open the pressure relief hole.

[0014] The key to this delayed exhaust valve lies in its sealing element (such as a ball). When the seat ring is pressed down by the user's weight, it forces the sealing element to move down and seal the pressure relief hole, preventing the gas in the storage cylinder from escaping. When the user leaves the seat and the seat ring rises, the third return spring pushes the sealing element up to reset, opening the pressure relief hole and allowing the gas in the storage cylinder to slowly escape. This purely mechanical sensing and control mechanism ensures that the seat ring will only start escaping and unlocking after the user has safely left, and the escaping rate (i.e., the delay time) can be precisely controlled by design to achieve safe and reliable automatic upward triggering.

[0015] In some embodiments, it further includes: two oil cores, one end of each oil core being connected to the end of the rotating shaft and the other end being connected to the seat ring.

[0016] The oil core connected between the pivot and the seat provides crucial damping and cushioning. When the main shaft spring releases energy to drive the pivot to reverse and cause the seat to flip upward, the oil core can effectively slow down the upward speed of the seat, significantly reduce motion noise, and prevent the seat from violently colliding with the toilet or back cover, thereby improving the safety and comfort of the product and also helping to extend the service life of related moving parts.

[0017] In some embodiments, it further includes: a first seal disposed around the piston of the first cylinder and abutting against the inner sidewall of the first base.

[0018] The first sealing element (such as a rubber cup) is tightly ringed on the piston, and its side abuts against the inner wall of the drive cylinder to form a dynamic seal. This ensures the effective sealing of the compressed air in the cylinder during the reciprocating motion of the piston, preventing gas leakage and loss of driving force. It is a key component to ensure the efficient and reliable operation of the drive cylinder.

[0019] In some embodiments, it further includes a second seal that is annularly disposed on the piston of the second cylinder and abuts against the inner wall of the second base.

[0020] The second sealing element (such as a V-shaped rubber) is tightly ringed on the piston of the first cylinder, and its side abuts against the inner wall of the storage cylinder to form a static seal. It can provide excellent sealing effect, especially under the pressure of inflation, to ensure that the storage cylinder can reliably maintain internal air pressure during the locking period, prevent gas leakage from causing premature unlocking failure, and ensure the stability of the automatic flip-up function.

[0021] In some embodiments, the shaft pressing part is a cylindrical structure that is off-center from the shaft center;

[0022] When the shaft rotates in the forward direction, the eccentric design gradually increases the contact arm between the pressing part and the drive cylinder, achieving progressive pressurization and ensuring that the gas in the cylinder is fully compressed. At the same time, the cylindrical profile matches the piston surface throughout the entire stroke, avoiding stress concentration and improving sealing durability. In addition, this integrated design eliminates the need for additional linkage mechanisms, reduces lateral space occupation, and is suitable for compact toilet layouts. Attached Figure Description

[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0043] This utility model provides a toilet seat with an automatically flip-up seat ring, comprising: a seat hinge 28, a seat ring 23, a rotating shaft 15 rotatably mounted on the seat hinge 28 and connected to the seat ring 23 at both ends, the rotating shaft 15 having a rotating shaft pressing part 15-1 and a rotating shaft hook 15-2, a main shaft spring 16 annularly mounted on the rotating shaft 15 and abutting against the seat hinge 28 and the rotating shaft 15 at both ends, which retracts when an external force drives the seat ring 23 and the rotating shaft 15 to rotate downwards synchronously, a drive cylinder 21 and a storage cylinder 22 disposed within the seat hinge 28 and corresponding to the rotating shaft pressing part 15-1 and the rotating shaft hook 15-2 respectively, the drive cylinder 21 and the storage cylinder 22 being interconnected and both having their drive ends movably extending out of the upper surface of the seat hinge 28, the drive cylinder 21 being activated when the rotating shaft 15 rotates downwards synchronously, the main shaft spring 16 ... When rotating, the air inside is squeezed by the shaft pressing part 15-1, which discharges the internal air into the air storage cylinder 22. This causes the drive end of the air storage cylinder 22 to move upward and engage the shaft hook 15-2. The delayed exhaust valve 10, which is located inside the seat hinge 28 and whose upper end can extend movably out of the seat hinge 28, is connected to the air storage cylinder 22. When the seat ring 23 rotates in the forward direction and contacts its upper end, and the human body sits on the seat ring 23, the upper end is driven downward by the seat ring 23 and is continuously pressured into a sealed state. After the human body leaves the seat ring 23, the upper end returns to its original position and discharges the gas in the air storage cylinder 22. This causes the drive end of the air storage cylinder 22 to descend and disengage from the shaft hook 15-2. Under the elastic force of the main shaft spring 16, the shaft 15 and the seat ring 23 rotate in the opposite direction and flip to a vertical state.

[0044] Specifically, the rotating shaft 15 has a concave design at the position corresponding to the rotating shaft pressing part 15-1, and the rotating shaft pressing part 15-1 is a cylindrical structure that is off-center from the center of the rotating shaft 15.

[0045] Specifically, the drive cylinder 21 includes: a first base 1, a first connector 6 disposed below the first base 1 and communicating with the first base 1, a one-way exhaust valve 5 disposed inside the first base 1 and corresponding to the first connector 6, a first upper cover 24 disposed above the first base 1 and covering the first base 1, a first cylinder piston 2 movably disposed in the first upper cover 24, and a first return spring 4 disposed inside the first base 1 and whose two ends respectively abut against the first base 1 and the first cylinder piston 2.

[0046] Specifically, the gas storage cylinder 22 includes: a second base 26, a second connector 8 disposed below the second base 26 and communicating with the drive cylinder 21 and the time-delayed exhaust valve 10, a second upper cover 25 disposed above the second base 26 and covering the second base 26, a second cylinder piston 11 movably disposed in the second upper cover 25, a second cylinder piston hook 11-1 with an opening at the upper end that engages with the rotating shaft hook 15-2, and a second return spring 13 disposed inside the second base 26 and with both ends abutting against the second upper cover 25 and the second cylinder piston 11 respectively.

[0047] Specifically, the first connector 6 and the second connector 8 are connected through the first air tube 7.

[0048] Specifically, the delayed exhaust valve 10 includes: a valve seat 10-4 connected to the gas storage cylinder 22; a pressure relief hole in the middle; a V-shaped sealing sheet 10-3 fitted on the pressure relief hole; a plug 10-1 movably disposed in the valve seat 10-4 and extending out of the valve seat 10-4 at its upper end; the lower end of the plug 10-1 being adapted to the shape of the sealing sheet 10-3; and a third return spring 10-2 disposed in the valve seat 10-4 and abutting against the valve seat 10-4 and the plug 10-1 at both ends respectively.

[0049] Specifically, the second connector 8 has a double-pass structure, with one end connected to the first air pipe 7 and the other end connected to it through the second air pipe 9. The other end of the second air pipe 9 is connected to the valve seat 10-4 of the time-delay exhaust valve 10.

[0050] The core of this invention lies in providing a purely mechanically controlled automatic seat-lifting solution. When the user needs to use the toilet, they manually press down the seat ring 23 to place it horizontally. This action simultaneously drives the rotating shaft 15 to rotate, at which point the arc-shaped pressing part 15-1 on the side of the rotating shaft 15 will press down on the first cylinder piston 2 of the drive cylinder 21. It is worth noting that, because the drive cylinder 21 is equipped with a one-way exhaust valve 5, it ensures that the gas can only flow in one direction. When the first cylinder piston 2 is pressed down, the air in the cylinder is forced out and transported to the air storage cylinder 22 through the first air pipe 7. The whole process is similar to pressurizing a bicycle pump.

[0051] Next, the compressed air enters the storage cylinder 22, which pushes the second cylinder piston 11 inside to move upward. The key design here is that the second cylinder piston 11 has a special second cylinder piston hook 11-1 at its top, and a hook structure extends from the rotating shaft 15. When the second cylinder piston 11 rises to its top, the second cylinder piston hook 11-1 will precisely engage with the rotating shaft hook 15-2, forming a mechanical lock. At the same time, the initial rotation of the rotating shaft 15 has caused the main shaft spring 16 surrounding it to accumulate torsional elasticity—it is this locked elasticity that becomes the core power source for the subsequent automatic upward tilting.

[0052] To achieve the safety logic of "triggering the upward tilt only after the user leaves the seat," this solution features a unique mechanical induction delay system. When the seat ring 23 tilts downward and a person sits on it, the outward-protruding part at the bottom of the seat ring 23 contacts the sealing element 10-1 on the delayed exhaust valve 10. At this time, the seat ring 23 slightly sinks due to the pressure exerted by the user's weight. This slight displacement causes the sealing element 10-1 inside to move downward and compress the third return spring 10-2. The lower end of the sealing element 10-1 cooperates with the opening to block the pressure relief hole. At this time, the entire air circuit is sealed, and the air in the air storage cylinder 22 cannot leak. Until the user gets up and leaves, the weight of the seat ring 23 disappears, and the third return spring 10-2 inside the exhaust valve 10 immediately pushes up the sealing element 10-1, reopening the pressure relief hole. Air will be slowly discharged at a controllable speed (about 3-5 seconds). When the pressure in the air storage cylinder 22 drops to the critical point, the piston 11 of the second cylinder falls under the action of the internal second spring, and the rotating shaft hook 15-2 is released accordingly.

[0053] In the final stage, the rotating shaft 15 automatically rotates in the reverse direction under the drive of the pre-stored main shaft spring 16. To ensure a smooth and quiet upward movement of the seat ring 23, hydraulic buffer oil cores 18 are specially connected to both ends of the rotating shaft 15. When the spring force of the main shaft spring 16 drives the rotating shaft 15 to rotate, the oil core 18 generates viscous resistance, causing the seat ring 23 to slowly rise at a uniform speed of 15°-20° per second, eventually stabilizing at a vertical position of 80°-90°.

[0054] Specifically, the hinge 28 includes a third base 27 and a third upper cover 14 disposed on it. A fixing block 19 is provided on the third base 27 for engaging the third upper cover 14. The third upper cover 14 has a hinge hole for rotatably connecting with the rotating shaft 15. In addition, a decorative shell 20 can be placed on the third upper cover 14 to seal the rotating shaft 15 and the main shaft spring 16 on the rotating shaft 15.

[0055] Specifically, the seat ring 23 is connected to the oil core 18 through the seat ring connecting sleeve 17.

[0056] Detailed optimizations of core components:

[0057] The cylinder diameter of the drive cylinder 21 is designed to be 10-50mm (preferably 30mm) to ensure that a single press can deliver a sufficient amount of gas.

[0058] The surface of the piston 2 of the first cylinder is nested with the first sealing element 3 (bowl-shaped sealing ring), which is made of fluororubber and maintains elastic sealing under frequent compression.

[0059] The piston 11 of the second cylinder is surrounded by a second seal 12 (V-shaped seal ring), which has a pressure self-tightening characteristic - the higher the internal air pressure, the stronger the sealing lip and the cylinder wall fit together, effectively preventing slow air leakage.

[0060] The pressure relief orifice of the delayed exhaust valve 10 is precisely designed with a diameter of 0.8mm, and is equipped with a return spring of specific stiffness to ensure a buffer time of 3-5 seconds.

[0061] The hydraulic oil core 18 uses high-temperature viscous silicone oil, with a viscosity change rate of less than 10% in an environment ranging from -10℃ to 60℃, ensuring consistent buffering throughout the four seasons.

[0062] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
