Abstract

The present invention relates to an automatic flip-up mechanism and a toilet, comprising a fixed support and a toilet. The seat ring is hinged to the fixed support, and the seat ring rotates relative to the fixed support to have an open position and a locked position. A first elastic member acts between the fixed support and the seat ring, and is used to provide the seat ring with an elastic force for positive rotation relative to the fixed support, thereby eliminating the need for circuit conditions in the use environment. A rotation stop is provided on the fixed support, and a blocking portion is provided on the seat ring. When the seat ring rotates relative to the fixed support to the open position, the rotation stop is blocked in the positive rotation direction of the blocking portion, effectively preventing the seat ring from colliding with other structures due to excessive positive rotation angle. A locking assembly is also provided between the fixed support and the seat ring. The locking assembly is in a locked state. When the seat ring is reversed to the locked position relative to the fixed support, the locking assembly can be switched to a locked state to prevent the seat ring from positive rotation relative to the fixed support, making it easier for the user to sit down.

Description

Technical Field

[0001] The present invention relates to the technical field of bathrooms, in particular to an automatic flip cover mechanism and a toilet. Background Art

[0002] With the advancement of bathroom technology, toilets are becoming increasingly automated. Automatic seat lifts are one way to demonstrate this level of automation. A motor drives the seat to rotate relative to the seat, and an electrical component, such as a sensor module, is added. The motor detects an electrical signal to drive the seat rotation. However, using electrical components to drive seat rotation requires specific application scenarios; for example, it cannot be used in environments without electrical circuits. Furthermore, electrical components are costly and have a short service life.

[0003] The use of a mechanical structure to drive the seat ring to rotate eliminates the dependence on the electrical environment, but there are problems such as the seat ring easily colliding with the seat body or the cover, and it is inconvenient to sit down. Summary of the Invention

[0004] Therefore, it is necessary to address the above issues by providing an automatic flip-up mechanism and toilet seat. This mechanism utilizes a first elastic member to drive the seat ring to rotate forward relative to the fixed support, thereby eliminating the need for circuit conditions in the operating environment. Furthermore, a rotation stop and a locking assembly are provided. The rotation stop and the blocking portion cooperate to precisely control the seat ring in the open position, effectively preventing the seat ring from rotating excessively and colliding with other structures. The locking assembly locks the seat ring in the locked position, making it easier for the user to sit down.

[0005] An automatic flip cover mechanism, comprising:

[0006] Fixed support;

[0007] a seat ring, the seat ring being hinged to the fixed support, the seat ring being rotatable relative to the fixed support to have an open position and a locked position, and the rotation direction of the seat ring when rotating from the open position to the locked position is a reverse direction;

[0008] a first elastic member, the first elastic member acting between the fixed support and the seat ring, and being used to provide an elastic force for the seat ring to rotate forward relative to the fixed support;

[0009] The fixed support is provided with a rotation stopper, and the seat ring is provided with a blocking portion, and when the seat ring rotates forward to the open position relative to the fixed support, the rotation stopper blocks the blocking portion in the forward rotation direction;

[0010] A locking assembly is further provided between the fixed support and the seat ring. The locking assembly is in a locked state. When the seat ring is reversed to a locked position relative to the fixed support, the locking assembly can be switched to a locked state to prevent the seat ring from rotating forward relative to the fixed support.

[0011] In one embodiment, the seat ring is hinged to the fixed support through a hinge shaft, and the stop member protrudes outside the fixed support in a direction intersecting with the axial direction of the hinge shaft. A stop groove is provided at a position facing the stop member when the seat ring rotates. When the seat ring rotates relative to the fixed support, the end of the stop member can slide in the stop groove along the reversal direction. The blocking portion includes a blocking wall of the stop groove. When the seat ring is reversed to the locked position, the stop member blocks the forward rotation direction of the blocking wall.

[0012] In one embodiment, the seat ring includes a ring body and two lugs spaced apart in the axial direction of the hinge shaft, the two lugs are connected to the ring body, the fixed support is located between the two lugs, each lug is hinged to the fixed support via the hinge shaft, and the elastic member acts between the lugs and the fixed support;

[0013] The anti-rotation groove is formed on the surface of the ring body facing the fixed support, the windward surface of the ring body when rotating forward is the seating surface, and the anti-rotation groove penetrates the seating surface of the ring body along the thickness direction of the ring body;

[0014] The direction in which the anti-rotation member protrudes from the fixed support is perpendicular to the axial direction of the hinge shaft.

[0015] In one embodiment, the locking assembly includes a slider and a first hook provided on the seat ring, and the slider is provided with a second hook;

[0016] The slider is slidably arranged on the fixed support, and the slider can slide between a forward position and a backward position relative to the fixed support. When the slider is in the forward position and the seat is in the locked position, the first hook is hooked on the second hook and the locking assembly is in a locked state. When the slider is in the backward position, the second hook is disengaged from the first hook and the locking assembly is in an unlocked state.

[0017] In one embodiment, the locking assembly further includes a third elastic member, which acts between the slider and the fixed support to provide elastic force for the slider to slide from the retreat position to the advance position.

[0018] In one embodiment, the seat ring is further provided with an unlocking trigger member, and the slider is provided with a pushing member. After the seat ring continues to rotate relative to the fixed support by a preset angle from the locked position, the first hook is disengaged from the second hook. When the seat ring continues to rotate, the unlocking trigger member acts on the pushing member, providing the pushing member with a force that overcomes the elastic force of the third elastic member, so that the slider moves to the retreated position.

[0019] The fixed support is further provided with a switching component, and the switching component is in a non-slip state. The switching component in the non-slip state is used to prevent the sliding block located in the retreat position from sliding toward the forward position.

[0020] In one embodiment, the anti-rotation member is slidably inserted into the fixed support along a first direction;

[0021] A second elastic member is provided between the anti-rotation member and the fixed support, and the second elastic member is used to provide the anti-rotation member with an elastic force extending outward from the fixed support along the first direction, and the anti-rotation member extends outward from one end of the fixed support to block the positive rotation direction of the blocking part when the seat is in the locking position.

[0022] In one embodiment, the switching assembly also has a released state, the seat ring located in the open position provides the anti-rotation member with a pressure force to overcome the pressing force of the second elastic member, and the anti-rotation member slides into the fixed support under the action of the pressing force and triggers the switching assembly to switch to the released state, and the slider can slide from the rear position to the forward position relative to the switching assembly in the released state.

[0023] In one embodiment, the switching assembly includes an elastic telescopic unit, one end of which is connected to the fixed support, and the elastic telescopic unit includes an anti-slip portion, and when the elastic telescopic unit is deformed, the anti-slip portion slides relative to the slider in the extension direction of the elastic telescopic unit;

[0024] In the anti-slip state, the elastic telescopic unit has a first deformation amount, and the anti-slip portion abuts against the slider at the retreated position to prevent the slider from sliding toward the forward position;

[0025] In the released state, the elastic telescopic unit has a second deformation amount, the anti-slip portion is staggered from the slider, and the second deformation amount is different from the first deformation amount;

[0026] When the anti-rotation member slides into the fixed support, it can drive the elastic telescopic unit to undergo a second deformation.

[0027] In one embodiment, the sliding direction of the anti-rotation member relative to the fixed support is consistent with the telescopic deformation direction of the elastic telescopic unit, and the end of the elastic telescopic unit that is not connected to the fixed bracket is located on the sliding path of the anti-rotation member sliding into the fixed support.

[0028] In one embodiment, the slider is provided with a through-hole passing through the direction of telescopic deformation of the elastic telescopic unit, the elastic telescopic unit passes through the through-hole, and one end is connected to the fixed support, and the other end corresponds to the anti-rotation member, the second deformation is greater than the first deformation, the portion of the elastic telescopic unit located in the through-hole when the second deformation occurs is a thin rod segment, and the outer diameter of the anti-slip portion is greater than the outer diameter of the thin rod segment;

[0029] When the thin rod section contacts the hole wall of the perforation, the slider is in the forward position, and the shoulder formed at the junction of the anti-slip portion and the thin rod section presses on the slider, and the slider prevents the elastic telescopic unit from changing to the state of the first deformation amount.

[0030] In one embodiment, the seat ring has a trigger slope. When the seat ring is rotated to the open position, the end of the anti-rotation member extending outside the fixed support slides over the trigger slope. The point of action on the trigger slope that abuts the anti-rotation member is a marking point. During the forward rotation of the seat ring, the distance between the marking point and the rotation axis of the seat ring gradually decreases, and the first direction is perpendicular to the rotation axis of the seat ring.

[0031] In one embodiment, when the unlocking trigger member and the pushing member interact with each other, at least one of the contact surfaces thereof is a guiding slope, and a guiding direction of the guiding slope intersects with a deformation direction of the third elastic member.

[0032] A toilet comprises a seat body and any one of the above-mentioned automatic flip cover mechanisms, wherein the fixed support is mounted on the seat body.

[0033] The above solution provides an automatic flip mechanism and toilet seat that utilizes a first elastic member to drive the seat ring to rotate forward relative to a fixed support, thereby eliminating the need for electrical circuitry in the operating environment. Unlike motor-driven seat rings, seat rings driven by the first elastic member cannot be controlled to stop rotation at any time by starting and stopping the driving member. Therefore, a rotation stop and a locking assembly are further provided. The rotation stop, in conjunction with a blocking portion, precisely locks the seat ring in the open position, effectively preventing excessive forward rotation and collision with other structures. The locking assembly locks the seat ring in the locked position, facilitating seating. Specifically, the user can manually rotate the seat ring to the locked position. Once the seat ring reaches the locked position, the locking assembly overcomes the elastic force of the first elastic member and secures the seat ring in this position. Once the user removes the force driving the seat ring to rotate backward, the seat ring will not rotate forward, even with the presence of the first elastic member, facilitating seating.

[0049] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0050] like Figure 1 and Figure 2 As shown, in some embodiments of the present application, an automatic flip cover mechanism 10 is provided, comprising a fixed support 11 and a seat ring 12. The seat ring 12 is hinged to the fixed support 11, and the seat ring 12 rotates relative to the fixed support 11 to have an open position and a locked position. The rotation direction of the seat ring 12 when rotating from the open position to the locked position is a reverse direction. Figure 3 and Figure 11 The direction shown by the middle arrow N1 is the forward direction, and the opposite direction is the reverse direction. It can be understood that the direction of rotation when the seat circle 12 is lifted is the forward direction.

[0051] When the user sits down, the seat 12 is pressed against the seat body 21, and is in the seated position. In some cases, the seat 12 in the open position rotates 90° relative to the seat 12 in the seated position. During the rotation from the open position to the seated position, the seat 12 passes through a locked position. In some embodiments, the seat 12 in the locked position rotates 5° relative to the seat 12 in the seated position.

[0052] Furthermore, in some embodiments, the automatic flip mechanism 10 further includes a first elastic member (not shown) that acts between the fixed support 11 and the seat ring 12 to provide an elastic force for the seat ring 12 to rotate forward relative to the fixed support 11. The seat ring 12 can be automatically flipped up under the action of the first elastic member. The first elastic member can be a torsion spring.

[0053] like Figures 1 to 4 As shown, the fixed support 11 is provided with a rotation stop 111. Figure 5 and Figure 6 As shown, the seat ring 12 is provided with a blocking portion 1231. When the seat ring 12 is rotated forwardly relative to the fixed support 11 to the open position, the rotation stop 111 blocks the forward rotation direction of the blocking portion 1231, so that the seat ring 12 can only rotate forwardly relative to the fixed support 11 to the open position, preventing the seat ring 12 from being lifted up at an excessive angle and hitting the toilet lid or other structures behind it.

[0054] like Figure 3 As shown, a locking assembly 13 is further provided between the fixed support 11 and the seat ring 12. The locking assembly 13 is in a locked state. When the seat ring 12 is reversed to a locked position relative to the fixed support 11, the locking assembly 13 can be switched to a locked state to prevent the seat ring 12 from rotating forward relative to the fixed support 11.

[0055] The first elastic member drives the seat 12 to rotate forward relative to the fixed support 11, eliminating the need for electrical circuit conditions in the operating environment. Unlike motor-driven seat 12, seat 12 driven by the first elastic member cannot be controlled to stop rotation at any time by starting and stopping the driver. Therefore, a rotation stop 111 and a locking assembly 13 are further provided. The rotation stop 111, in conjunction with the blocking portion 1231, precisely locks the seat 12 in the open position, effectively preventing excessive forward rotation and collision with other structures. The locking assembly 13 locks the seat 12 in the locked position, making it easier for the user to sit down. Specifically, the user can manually rotate the seat 12 to the locked position. Once the seat 12 reaches the locked position, the locking assembly 13 overcomes the elastic force of the first elastic member and secures the seat 12 in this position. Once the user removes the force driving the seat 12 to rotate backward, the seat 12 will not rotate forward, even with the presence of the first elastic member, making it easier to sit down.

[0056] First, the specific structures of the anti-rotation member 111 and the blocking portion 1231 in some embodiments are described by way of example:

[0057] The seat ring 12 is hinged to the fixed support 11 via a hinge shaft (not shown in the figure), and the anti-rotation member 111 protrudes from the fixed support 11 along a direction intersecting the axial direction of the hinge shaft. Figure 5 and Figure 6 As shown, a stop groove 123 is provided at a position facing the stop member 111 when the seat ring 12 rotates. When the seat ring 12 rotates relative to the fixed support 11, the end of the stop member 111 can slide in the stop groove 123 along the reverse direction. Figure 6 As shown, the blocking portion 1231 includes the blocking wall of the anti-rotation groove 123. Figure 4 As shown, when the seat ring 12 is reversed to the locking position, the rotation-stopping member 111 blocks the forward rotation direction of the blocking wall.

[0058] like Figure 3 The figure shows a cross-sectional view of the automatic cover flipping mechanism 10 when the seat ring 12 is in the locked position, and the anti-rotation member 111 is not in the anti-rotation groove 123 provided on the seat ring 12. Figure 4 Taking the angle shown as an example, when the seat ring 12 rotates clockwise relative to the fixed support 11, the anti-rotation groove 123 gradually approaches the anti-rotation member 111. As the rotation angle of the seat ring 12 increases, the end of the anti-rotation member 111 gradually slides into the anti-rotation groove 123 until the anti-rotation member 111 abuts against the blocking wall of the anti-rotation groove 123.

[0059] The portion of the groove wall of the anti-rotation groove 123 that contacts the end surface of the anti-rotation member 111 when the anti-rotation member 111 slides in the anti-rotation groove 123 is defined as the side wall, and the blocking wall is the bottom wall of the anti-rotation groove 123.

[0060] Specifically in some embodiments, Figure 5 and Figure 6 As shown, the seat ring 12 includes a ring body 121 and two lugs 122 spaced apart in the axial direction of the hinge shaft, and both lugs 122 are connected to the ring body 121. Figure 1 and Figure 2 As shown, the fixed support 11 is located between the two lugs 122. Each lug 122 is hinged to the fixed support 11 via the hinge shaft, and the elastic member acts between the lug 122 and the fixed support 11.

[0061] like Figure 5 and Figure 6 As shown, the anti-rotation groove 123 is formed on the surface of the ring body 121 facing the fixed support 11. Figure 1 and Figure 2 As shown, the windward surface of the ring body 121 when rotating forward is the seating surface 1211 , and the anti-rotation groove 123 penetrates the seating surface 1211 of the ring body 121 along the thickness direction of the ring body 121 to form an entrance on the seating surface 1211 .

[0062] Return to reference Figure 4 As shown, when the seat ring 12 rotates forward relative to the fixed support 11, the end of the stopper 111 slides from the incision into the stopper groove 123. As the seat ring 12 rotates forward more, the end of the stopper 111 gradually approaches the barrier wall until it abuts against the barrier wall. After the stopper 111 abuts the barrier wall, the seat ring 12 cannot rotate further forward relative to the fixed support 11.

[0063] More specifically, in one embodiment, Figure 3 and Figure 4 As shown, the direction in which the stopper 111 protrudes from the fixed support 11 is perpendicular to the axial direction of the hinge shaft. After the end of the stopper 111 enters the stopper groove 123 from the incision, the direction in which the stopper 111 protrudes from the fixed support 11 intersects with the depth direction of the stopper groove 123. Figure 4 At the angle shown, assuming that the fixed support 11 is stationary and the seat ring 12 is rotating forward, when the seat ring 12 is rotating forward to the vertical direction, the depth direction of the anti-rotation groove 123 is horizontal. At this time, the end of the anti-rotation member 111 is located in the anti-rotation groove 123, and the direction in which the end of the anti-rotation member 111 protrudes from the fixed support 11 is longitudinal.

[0064] In certain embodiments, as Figure 3 and Figure 4 As shown, the stopper 111 is slidably inserted into the fixed support 11 along the first direction. The direction in which the stopper 111 protrudes from the fixed support 11 is parallel to the first direction. Figure 4The direction indicated by the middle arrow N2 is the second direction. The anti-rotation member 111 is equivalent to a latch slidably inserted into the fixed support 11 .

[0065] A second elastic member 1112 is provided between the anti-rotation member 111 and the fixed support 11, and the second elastic member 1112 is used to provide an elastic force for the anti-rotation member 111 to extend outward from the fixed support 11 along the first direction. Figure 4 At the angle shown, the direction in which the stopper 111 extends outward from the fixed support 11 along the first direction is upward. The stopper 111 extends outward from one end of the fixed support 11 to block the forward rotation direction of the blocking portion 1231 when the seat 12 is in the locked position.

[0066] As the seat ring 12 rotates until the stop member 111 gradually enters the stop groove 123, if the sidewalls of the stop groove 123 act as a resisting force in the first direction on the stop member 111, the stop member 111 will slide slightly into the fixed support 11. In the first direction, the stop member 111 can float within a certain range relative to the fixed support 11, allowing the seat ring 12 to smoothly rotate to the open position.

[0067] In order to limit the protruding height of the anti-rotation member 111 outside the fixed support 11, in some cases, such as Figure 4 As shown, the stopper 111 is provided with a limiting protrusion 1111, and the fixed support 11 has a matching portion (not shown in the figure), which blocks the limiting protrusion 1111 from extending outward from the fixed support 11 along the first direction. When the stopper 111 is not in contact with the seat ring 12, the stopper 111 slides relative to the fixed support 11 under the action of the second elastic member 1112 to a position where the limiting protrusion 1111 and the matching portion abut against each other. When the seat ring 12 rotates until the stopper 111 enters the limiting groove 123, the stopper 111 can be pressed into the fixed support 11 by the seat ring 12. At this time, the stopper 111 can overcome the elasticity of the second elastic member 1112 and slide into the fixed support 11. At this time, the limiting protrusion 1111 is separated from the matching portion and arranged at intervals.

[0068] like Figure 4 As shown, in some embodiments, the second elastic member 1112 is a compression spring that acts directly or indirectly between the fixed support 11 and the anti-rotation member 111. For example, the anti-rotation member 111 can be inserted into the second elastic member 1112, with one end of the second elastic member 1112 abutting against the limiting protrusion 1111, and the other end of the second elastic member 1112 acting on the fixed support 11, thereby providing an elastic force for the anti-rotation member 111 to extend outward from the fixed support 11 along the first direction.

[0069] Next, the locking assembly 13 and its related structures in some embodiments are further described below:

[0070] For example, in some embodiments, Figure 4 As shown, the locking assembly 13 includes a slider 131 and a first hook 132 provided on the seat 12 , and a second hook 1311 is provided on the slider 131 .

[0071] The slider 131 is slidably disposed on the fixed support 11. The slider 131 can slide between an advanced position and a retreated position relative to the fixed support 11. When the slider 131 is in the advanced position and the seat 12 is in the locked position, the first hook 132 is hooked on the second hook 1311, and the locking assembly 13 is locked. As a result, the seat 12 cannot rotate forward relative to the fixed support 11. Figure 4 The state shown is the state when the seat ring 12 is in the locked position.

[0072] When the slider 131 is in the retreated position, the second hook 1311 is disengaged from the first hook 132, and the locking assembly 13 is in an unlocked state. Thus, the seat 12 can be rotated forward or reversely relative to the fixed support 11.

[0073] After the user manually rotates the seat 12 to the locked position and removes the manual force applied to the seat 12, the seat 12 will not rotate forward relative to the fixed support 11, but will remain in the locked position. Since the slider 131 can also slide to a retracted position, after using the toilet 20, the locking assembly 13 can be adjusted to the unlocked state, and the seat 12 can then be rotated back to the open position under the action of the first elastic member.

[0074] Optionally, in other embodiments, the locking assembly 13 may also be in other structural forms, as long as it exists in the aforementioned locking state.

[0075] There are various ways to adjust the locking assembly 13 to the unlocked state, such as manually adjusting the locking assembly 13 to the unlocked state, or triggering the locking assembly 13 to switch to the unlocked state by other actions. For example, when the seat 12 continues to rotate from the locked position to the seated position, the seat 12 may trigger the locking assembly 13 to switch to the unlocked state.

[0076] In certain embodiments, as Figure 4 As shown, the locking assembly 13 further includes a third elastic member 133, which acts between the slider 131 and the fixed support 11 to provide elastic force for the slider 131 to slide from the retreat position to the forward position. Under the action of the third elastic member 133, the slider 131 always tends to remain in the forward position. Figure 4At the angle shown, the third elastic member 133 provides the slider 131 with a force directed to the left.

[0077] Furthermore, in some embodiments, Figure 5 and Figure 6 As shown, the seat ring 12 is also provided with an unlocking trigger 124. Figures 7 to 9 As shown, the slider 131 is provided with a push member 1312. Figure 3 and Figure 4 As shown, after the seat 12 continues to rotate from the locked position relative to the fixed support 11 by a predetermined angle, the first hook 132 disengages from the second hook 1311. As the seat 12 continues to rotate, the unlocking trigger 124 acts on the push member 1312, providing a force for the push member 1312 to overcome the elastic force of the third elastic member 133, causing the slider 131 to move to the retracted position. Here, the continued rotation of the seat 12 acts as a trigger, which causes the slider 131 of the locking assembly 13 to switch to the retracted position, thereby unlocking the seat 12.

[0078] Furthermore, in some embodiments, when the unlocking trigger member 124 interacts with the push member 1312 , at least one of the contact surfaces thereof is a guide slope 1241 , and a guiding direction of the guide slope 1241 intersects with a deformation direction of the third elastic member 133 .

[0079] For example, in one embodiment, Figure 5 and Figure 6 As shown, the surface of the unlocking trigger 124 that contacts the push member 1312 is the guide slope 1241. Figures 7 to 9 As shown, the surface of the resisting member 1312 that contacts the unlocking trigger member 124 is the guiding slope 1241. The guiding direction of the guiding slope 1241 intersects the direction in which the slider 131 slides relative to the fixed support 11. When the seat 12 continues to reverse from the locked position, the unlocking trigger member 124 contacts the resisting member 1312, causing the slider 131 to slide toward the rearward position relative to the fixed support 11.

[0080] In order to ensure that the slider 131 can be kept in the retracted position when the seat 12 starts to rotate forward from the seated position so that the seat 12 can rotate forward to the open position, a switching component 14 can be further provided.

[0081] like Figures 7 to 9 As shown, the fixed support 11 is further provided with a switching component 14, and the switching component 14 is in a non-slip state. The switching component 14 in the non-slip state is used to prevent the slider 131 located in the retreat position from sliding toward the forward position.

[0082] Furthermore, in some embodiments, the switching assembly 14 also has a released state, and the seat ring 12 located in the open position provides the anti-rotation member 111 with a pressure force to overcome the second elastic member 1112, and the anti-rotation member 111 slides into the fixed support 11 under the action of the pressure force and triggers the switching assembly 14 to switch to the released state, and the slider 131 can slide from the rear position to the forward position relative to the switching assembly 14 in the released state.

[0083] It can be understood that the action of the seat ring 12 rotating forward to the open position can trigger the switching assembly 14 to switch to the released state through the anti-rotation member 111, thereby ensuring that the locking assembly 13 can switch to the unlocked state after the seat ring 12 rotates forward to the open position, preparing for the next reverse locking of the seat ring 12 in the locked position.

[0084] In some embodiments, as Figure 6 As shown, the seat ring 12 has a trigger slope 1232. During the process of the seat ring 12 rotating forward to the open position, the end of the anti-rotation member 111 extending outside the fixed support 11 slides over the trigger slope 1232. The point of action on the trigger slope 1232 that abuts against the anti-rotation member 111 is a marking point. During the forward rotation of the seat ring 12, the distance between the marking point and the rotation axis of the seat ring 12 gradually decreases, and the first direction is perpendicular to the rotation axis of the seat ring 12.

[0085] In some cases, the triggering inclined surface 1232 is a side wall surface of the anti-rotation groove 123. When the seat ring 12 rotates forward and the anti-rotation member 111 slides in the anti-rotation groove 123, the anti-rotation member 111 is gradually pressed and slid into the fixed support 11.

[0086] When the user manually reverses the seat ring 12 to the locked position, the locking assembly 13 can be switched to a locked state, thereby locking the seat ring 12 in the locked position.

[0087] When the user sits down, the seat 12 continues to rotate relative to the locked position, triggering the locking assembly 13 to switch to the unlocked state. The switching assembly 14 switches to the anti-slip position, keeping the locking assembly 13 in the unlocked state. In this situation, when the user leaves, the seat 12 rotates back to the open position under the action of the first elastic member.

[0088] When the seat ring 12 is rotated to the open position, the stop member 111 triggers the switching assembly 14 to switch to the released state. The slider 131 will slide to the forward position under the action of the third elastic member 133 without being blocked by the switching assembly 14. The next time the seat ring 12 is reversed to the locked position, it can be locked again by the locking assembly 13.

[0089] like Figure 4 As shown, when the seat ring 12 is reversed to the locked position, the first hook 132 on the seat ring 12 can first squeeze the second hook 1311, so that the slider 131 overcomes the elastic force of the third elastic member 133 and slides slightly toward the backward position. After the first hook 132 squeezes and slides over the second hook 1311, the slider 131 returns to the forward position under the action of the third elastic member 133, and the first hook 132 is hooked with the second hook 1311, and the locking assembly 13 is in a locked state.

[0090] The states and positions of the various moving parts are summarized as follows:

[0091] The seat ring 12 has an open position, a locked position and a seated position;

[0092] The locking assembly 13 has a locked state and an unlocked state, and the slider 131 has a forward position and a backward position. In the locked state, the slider 131 included in the locking assembly 13 is located in the forward position, and in the unlocked state, the slider 131 included in the locking assembly 13 is located in the backward position.

[0093] The switch assembly 14 has a non-slip state and a released state.

[0094] Specifically, in some embodiments, Figures 7 to 10 As shown, the switching assembly 14 includes an elastic telescopic unit, one end of which is connected to the fixed support 11, and the elastic telescopic unit includes a non-slip portion 1411. When the elastic telescopic unit is deformed, the non-slip portion 1411 slides relative to the slider 131 in the telescopic direction of the elastic telescopic unit.

[0095] In the anti-slip state, the elastic telescopic unit has a first deformation amount, and the anti-slip portion 1411 abuts against the slider 131 located in the retreated position to prevent the slider 131 from sliding toward the forward position;

[0096] In the released state, the elastic telescopic unit has a second deformation amount, the anti-slip portion 1411 is staggered from the slider 131, and the second deformation amount is different from the first deformation amount;

[0097] When the anti-rotation member 111 slides into the fixed support 11 , it can drive the elastic telescopic unit to undergo a second deformation.

[0098] The elastic telescopic unit switches the switch assembly 14 between the anti-slip state and the release state by telescopic deformation. When the anti-rotation member 111 slides into the fixed support 11, the elastic telescopic unit is triggered to undergo telescopic deformation, and the deformation amount thereof is the second deformation amount.

[0099] When the seat ring 12 is rotated to the open position, the anti-rotation member 111 provides a pressing force. Under the action of the pressing force, the anti-rotation member 111 overcomes the elastic force of the second elastic member 1112 and slides into the fixed support 11. During the sliding process, the anti-rotation member 111 can drive the elastic telescopic unit to undergo elastic deformation, thereby changing the position of the anti-slip part 1411.

[0100] Specifically, a transmission structure may be arranged on the sliding path of the anti-rotation member 111 , and the transmission structure is used to apply a force to the elastic telescopic unit, so that the elastic telescopic unit undergoes a second deformation.

[0101] Or, as Figure 7 As shown, the sliding direction of the stop member 111 relative to the fixed support 11 is consistent with the direction of the telescopic deformation of the elastic telescopic unit. The end of the elastic telescopic unit not connected to the fixed bracket is located on the sliding path of the stop member 111 into the fixed support 11. As the stop member 111 slides into the fixed support 11, it presses against the elastic telescopic unit, causing the elastic telescopic unit to undergo telescopic deformation by a second deformation amount, thereby changing the position of the anti-slip portion 1411, causing the anti-slip portion 1411 to be offset from the slider 131. On this basis, the slider 131 can slide to the forward position under the action of the third elastic member 133.

[0102] In some embodiments, as Figure 7 and Figure 8 As shown, the slider 131 is provided with a through hole 1313 that passes through the direction of the elastic expansion unit. The elastic expansion unit passes through the through hole 1313 and is connected to the fixed support 11 at one end and corresponds to the anti-rotation member 111 at the other end. The second deformation is greater than the first deformation. Figure 9 and Figure 10 As shown, the portion of the elastic telescopic unit located in the through hole 1313 when the second deformation occurs is the thin rod segment 1412 , and the outer diameter of the anti-slip portion 1411 is greater than the outer diameter of the thin rod segment 1412 .

[0103] When the thin rod segment 1412 is located in the through hole 1313, based on the smaller outer diameter of the thin rod segment 1412, the slider 131 can slide toward the forward position under the action of the third elastic member 133. When the slider 131 slides to the hole wall of the through hole 1313 and abuts against the thin rod segment 1412, the slider 131 is in the forward position.

[0104] The outer diameter of the anti-slip portion 1411 is larger, so when the anti-slip portion 1411 is located in the through hole 1313, the sliding movement of the slider 131 in the forward direction is limited. When the anti-slip portion 1411 contacts the hole wall of the through hole 1313, the slider 131 is in the backward position.

[0105] like Figure 10 As shown, in some embodiments, the elastic expansion unit includes a stepped boss 141 and a fourth elastic member 142. The fourth elastic member 142 acts between the stepped boss 141 and the fixed support 11. The stepped boss 141 includes a thin rod section 1412 and a non-slip portion 1411. The deformation direction of the fourth elastic member 142 is the direction of expansion and contraction of the elastic expansion unit. For example, in some embodiments, the deformation direction of the fourth elastic member 142 is consistent with the sliding direction of the non-rotating member 111 relative to the fixed support 11.

[0106] More specifically, Figure 8 As shown, the through hole 1313 includes a narrow hole for the thin rod section 1412 to pass through and a wide hole for the anti-slip portion 1411 to pass through. The outer diameter of the anti-slip portion 1411 is larger than the width of the narrow hole, and the wide hole is located in the forward direction of the narrow hole.

[0107] When the slider 131 is in the forward position, the thin rod section 1412 is inserted into the narrow hole, and the anti-slip portion 1411 with a larger outer diameter is blocked under the slider 131, so that the elastic telescopic unit remains in the second deformation state.

[0108] When the slider 131 is located at the retreated position, the wide hole is opposite to the anti-slip portion 1411 , the anti-slip portion 1411 slides into the wide hole, and the deformation amount of the elastic expansion unit becomes the first deformation amount.

[0109] The following is a detailed description of the entire cycle of the seat ring 12 in forward and reverse rotation:

[0110] State 1: The seat ring 12 is in the open position. At this time, the anti-rotation member 111 provides a force for the elastic telescopic unit, causing the elastic telescopic unit to undergo the second deformation. The thin rod segment 1412 is inserted into the through-hole 1313, the anti-slip portion 1411 is located outside the through-hole 1313, and the slider 131 is in the forward position. The shoulder formed at the intersection of the anti-slip portion 1411 and the thin rod segment 1412 presses against the slider 131. The slider 131 prevents the elastic telescopic unit from changing to the first deformation state. In other words, the slider 131 in the forward position can prevent the elastic telescopic unit from switching to the first deformation state.

[0111] State 2: After the seat ring 12 rotates to remove the force applied to the anti-rotation member 111, the elastic expansion unit remains in the second deformation state under the action of the slider 131. The seat ring 12 continues to rotate to the locked position, and the first hook 132 and the second hook 1311 are hooked together, and the seat ring 12 remains in the locked position.

[0112] State Three: As the seat 12 continues to rotate from the locked position, the unlocking trigger 124 contacts the push member 1312, causing the slider 131 to slide toward the rearward position. As the slider 131 slides toward the rearward position, the first hook 132 disengages from the second hook 1311. Furthermore, once the previously pressed shoulder is freed from the restraint of the slider 131, the elastic expansion unit elastically deforms toward the first deformation amount, and the anti-slip portion 1411 slides into the through-hole 1313. This allows the slider 131 to remain in the rearward position. After the user leaves the toilet 20, the seat 12 rotates back to the open position under the action of the first elastic member, returning to State One.

[0113] Furthermore, in some embodiments of the present application, a toilet 20 is provided, such as Figure 11 As shown, it includes a base body 21 and any one of the above-mentioned automatic flip cover mechanisms 10 , and the fixed support 11 is installed on the base body 21 .

[0114] By employing the automatic flip mechanism 10 described in any of the above embodiments, the automatic flip function is achieved without relying on the circuit environment. Furthermore, the rotation stop 111 cooperates with the blocking portion 1231 to accurately limit the seat 12 to the open position, effectively preventing the seat 12 from rotating too far forward and colliding with other structures. The locking assembly 13 locks the seat 12 in the locked position, making it easier for the user to sit down.
