[0004] After searching, it was found that the above patent requires the user's own weight to press down the seat ring when the seat ring needs to fit with the toilet seat. At that time, this method is prone to the seat ring automatically resetting when the user's body moves, causing the seat ring to accidentally reset when the user does not want it to reset, causing unnecessary interference and inconvenience. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides an automatic ejection structure of a toilet lid, which solves the problem that when the seat ring needs to be fitted with the toilet seat, the user's own weight is required to press it down.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic spring-opening structure for a toilet lid, comprising a toilet seat, a water tank, a seat cushion, a lid body, a spring-back assembly and a control assembly;

[0007] The water tank is mounted on the toilet seat, and a button for controlling drainage is mounted on the water tank. The seat cushion is mounted on the toilet seat through a rebound assembly so that the seat cushion can automatically rebound when not in use. The cover body is hinged to the seat cushion through a hinge shaft.

[0008] The control component is assembled on the water tank and is transmission-connected with the button to control the rebound of the seat cushion.

[0009] Further, the rebound assembly includes a protrusion integrally formed on the side of the seat cushion close to the water tank, and at least two bearing seats are spaced apart on the upper side of the toilet seat along the Y-axis direction;

[0010] At least two of the bearing seats are rotatably connected to a rotating shaft, and at least two of the rotating shafts are respectively installed on the front and rear sides of the protrusion. At least two of the bearing seats are installed with a first torsion spring on the side opposite to the protrusion, so that the seat cushion rotates toward the toilet seat to twist the first torsion spring.

[0011] Furthermore, at least two of the first torsion springs are respectively sleeved on the outer sides of at least two rotating shafts.

[0012] Furthermore, at least two ends of the rotating shafts that are opposite to each other respectively penetrate and extend to the opposite sides of at least two bearing seats.

[0013] Furthermore, the rebound assembly further comprises a locking structure, which comprises at least two ratchets, at least two rotating rods, at least two mounting seats and at least two clamping plates;

[0014] At least two of the ratchets are fixedly sleeved on the outside of at least two rotating shafts, at least two of the rotating rods are respectively mounted on the front and rear sides of the water tank, at least two of the mounting seats are rotatably connected to the outside of at least two of the rotating rods, and at least two of the clamping plates are respectively arranged on at least two of the mounting seats;

[0015] A second torsion spring is installed between the mounting seat and a side opposite to the water tank.

[0016] Furthermore, the left end of the clamping plate extends into one of the tooth grooves of the ratchet wheel.

[0017] Further, the control assembly includes a connecting ring, at least two horizontal plates and at least two vertical plates;

[0018] The connecting ring is sleeved on the outside of the button, at least two of the horizontal plates are integrally formed and arranged on the outside of the connecting ring, and at least two of the horizontal plates are located in the same Y-axis direction, and at least two of the vertical plates are respectively assembled on the opposite sides of at least two of the horizontal plates;

[0019] The bottom ends of at least two of the vertical plates extend outward to form a pressing portion, and the at least two pressing portions are respectively attached to the upper surfaces of at least two clamping plates.

[0020] Furthermore, a gap is retained between the at least two horizontal plates and the upper surface of the water tank;

[0021] At least two positioning sleeves are installed on both the front and rear sides of the water tank and are respectively wrapped around the outside of at least two vertical plates.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] 1. The automatic pop-up structure of the toilet lid drives the connecting ring and the horizontal plate connected to it to move downward by pressing a button, thereby driving the two vertical plates to move downward, and pressing one end of the clamping plate through the downward pressing parts at the bottom ends of the two vertical plates, thereby lifting the end in contact with the ratchet wheel. At this time, the first torsion spring automatically rebounds without the action of external force, thereby driving the protrusion and the cushion to rotate toward the direction of the water tank, so that the cushion is separated from the toilet seat, and at the same time, the cushion is in a state perpendicular to the toilet seat.

[0024] 2. The automatic pop-up structure of the toilet lid drives the rotating shaft to rotate through the seat cushion and drives the ratchet connected to it to rotate, so that the ratchet rotates on the ZX plane. At the same time, the end of the clamping plate that is in contact with it will be lifted every time the ratchet rotates a distance of one tooth groove. The clamping plate drives the mounting base to rotate in a small range on the outside of the rotating rod, and at the same time twists the second torsion spring. Through the elastic force of the second torsion spring, one end of the clamping plate can effectively extend to one of the tooth grooves inside the ratchet, thereby locking the ratchet and achieving the same locking effect on the seat cushion.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1 In the automatic toilet lid rebound structure of the present embodiment, the seat cushion 3 can rebound automatically after the flush button 7 is pressed, and the seat cushion 3 cannot rebound automatically after the cover is closed.

[0033] Specifically, it includes a toilet seat 1, a water tank 2, a seat cushion 3, a cover body 4, a rebound component 5 and a control component 6; the water tank 2 is mounted on the toilet seat 1, and a button 7 for controlling drainage is mounted on the water tank 2, the seat cushion 3 is installed on the toilet seat 1 through the rebound component 5, so that the seat cushion 3 can automatically rebound when not in use, and the cover body 4 is hinged on the seat cushion 3 through a hinge shaft; the control component 6 is mounted on the water tank 2, and is transmission-connected to the button 7 for controlling the rebound of the seat cushion 3.

[0034] During actual use, through the cooperation of the control component 6 and the rebound component 5, the seat cushion 3 will automatically rebound after pressing the flush button 7, providing additional hygiene and convenience. There is no need to reset the seat cushion 3, and the seat cushion 3 will not automatically rebound when it is closed, which helps to ensure that the seat cushion 3 fits firmly on the toilet seat 1, providing a more stable use experience. In addition, there is no need to apply external force to maintain the state of the seat cushion 3.

[0035] See also Figure 2-5 In order to ensure that the seat cushion 3 can rebound automatically, the rebound component 5 in this embodiment includes a protrusion 501 integrally formed on the side of the seat cushion 3 close to the water tank 2, and at least two bearing seats 502 are arranged at intervals along the Y-axis direction along the upper edge of the toilet seat 1; at least two bearing seats 502 are rotatably connected to the interior of each of the shafts 503, and at least two shafts 503 are respectively installed on the front and rear sides of the protrusion 501, and at least two bearing seats 502 are installed on the side opposite to the protrusion 501. A first torsion spring 504 is installed, so that the seat cushion 3 twists the first torsion spring 504 when it rotates toward the toilet seat 1.

[0036] During actual use, the seat cushion 3 is rotated toward the toilet seat 1. At this time, the protrusion 501 twists the first torsion spring 504 connected thereto, so that the first torsion spring 504 has a certain elastic potential energy, and the first torsion spring 504 transmits its attached elastic force to the seat cushion 3, so that the seat cushion 3 also has the force to rotate toward the water tank 2.

[0037] Furthermore, in order to lock the seat cushion 3 and ensure that the seat cushion 3 does not automatically reset after being fitted with the toilet seat 1, the rebound component 5 in this embodiment also includes a locking structure, which includes at least two ratchets 505, at least two rotating rods 506, at least two mounting seats 507 and at least two clamping plates 508; at least two ratchets 505 are respectively fixedly mounted on the outside of at least two rotating shafts 503, at least two rotating rods 506 are respectively assembled on the front and rear sides of the water tank 2, at least two mounting seats 507 are respectively rotatably connected to the outside of at least two rotating rods 506, and at least two clamping plates 508 are respectively arranged on at least two mounting seats 507; a second torsion spring 509 is installed between the mounting seat 507 and the side opposite to the water tank 2.

[0038] It should be noted that, in order to lock the ratchet 505 and fix the angle of the seat cushion 3 at the same time, the left end of the clamping plate 508 in this embodiment extends into one of the tooth grooves of the ratchet 505 .

[0039] During actual use, the rotation of the rotating shaft 503 drives the ratchet 505 connected to it to rotate, and the ratchet 505 rotates on the ZX plane. At the same time, every time the ratchet 505 rotates a distance of one tooth groove, the end of the clamping plate 508 that is in contact with it will be lifted. The clamping plate 508 drives the mounting seat 507 to rotate in a small range on the outside of the rotating rod 506, and at the same time, the second torsion spring 509 is twisted. Through the elastic force of the second torsion spring 509, one end of the clamping plate 508 can effectively extend to one of the tooth grooves inside the ratchet 505, thereby locking the ratchet 505, and also achieving the locking effect of the seat cushion 3.

[0040] In actual settings, the ratchet 505, the rotating rod 506, the mounting seat 507 and the clamping plate 508 are combined to achieve reliable locking of the seat cushion 3, ensuring that the seat cushion 3 will not automatically reset after being fitted with the toilet seat 1, thereby providing a stable user experience.

[0041] In addition, at least two first torsion springs 504 are respectively sleeved on the outer sides of at least two rotating shafts 503 , and opposite ends of at least two rotating shafts 503 respectively penetrate and extend to opposite sides of at least two bearing seats 502 .

[0042] In actual configuration, the first torsion spring 504 is sleeved on the outer side of the rotating shaft 503 to provide additional support and elastic force, thereby helping to ensure the stability and durability of the locking structure.

[0043] See also Figure 3-5In order to facilitate the cushion 3 to pop up during flushing, the control assembly 6 in this embodiment includes a connecting ring 601, at least two horizontal plates 602 and at least two vertical plates 603; the connecting ring 601 is sleeved on the outside of the button 7, the at least two horizontal plates 602 are integrally formed and arranged on the outside of the connecting ring 601, and the at least two horizontal plates 602 are located in the same Y-axis direction, and the at least two vertical plates 603 are respectively assembled on the opposite sides of the at least two horizontal plates 602; the bottom ends of the at least two vertical plates 603 extend outward to form a pressing portion 604, and the at least two pressing portions 604 are respectively attached to the upper surfaces of the at least two clamping plates 508.

[0044] During actual use, by pressing the button 7, the connecting ring 601 and the horizontal plate 602 connected thereto are driven to move downward, thereby driving the two vertical plates 603 to move downward, and the downward pressing portion 604 at the bottom of the two vertical plates 603 presses one end of the clamping plate 508, thereby lifting the end in contact with the ratchet 505. At this time, the first torsion spring 504 automatically rebounds without the action of external force, thereby driving the protrusion 501 and the seat cushion 3 to rotate toward the direction of the water tank 2, so that the seat cushion 3 is separated from the toilet seat 1, and at the same time, the seat cushion 3 is in a state of being vertical to the toilet seat 1.

[0045] Furthermore, in order to facilitate pressing down the horizontal plate 602 and ensure the stability of the vertical plate 603 when moving downward, so that the pressing portion 604 at the bottom end of the vertical plate 603 can effectively contact the clamping plate 508, a gap is retained between at least two horizontal plates 602 and the upper surface of the water tank 2 in this embodiment; at least two positioning sleeves are installed on the front and rear sides of the water tank 2 and are respectively wrapped around the outside of at least two vertical plates 603.

[0046] During the actual setting, a certain gap is retained between the horizontal plate 602 and the upper surface of the water tank 2, so that the user can easily press the horizontal plate 602 to trigger related operations without feeling inconvenience or obstruction, and the vertical plate 603 is installed on the front and rear sides of the water tank 2 through the positioning sleeve to ensure that the vertical plate 603 remains stable when moving downward, and the downward pressing part 604 at the bottom can effectively contact the card plate 508, thereby ensuring the accuracy and reliability of the operation.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
