Description

Technical Field

[0001] The present invention relates to the field of dampers, and in particular to a one-way damper and a toilet. Background Art

[0002] Toilet lids are often connected to the toilet body via a damper to prevent the lid from colliding with the toilet body at high speed when closing, causing damage to the toilet. The dampers currently used in toilet lids on the market include a shell, a shaft, and oil-repelling blades. The shell forms an oil-sealing chamber filled with damping oil. When the shaft rotates, it drives the blades to squeeze the damping oil, which flows from a hole or groove to another chamber. Because the damping oil flows slowly in small holes or grooves, it creates a resistance to descent.

[0003] However, although this type of damper can slow down the closing speed of the toilet lid, it will also slow down the opening speed of the toilet lid, causing the user to spend more effort to open the toilet lid when using the toilet, and the toilet lid opens relatively slowly, affecting the user experience. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a one-way damper that can achieve a one-way damping effect and has no damping effect when rotating in the reverse direction.

[0005] The present invention also provides a toilet with the one-way damper.

[0006] The one-way damper according to the first embodiment of the present invention includes:

[0007] a first rotating member;

[0008] a rotating shaft, the rotating shaft being rotatably connected to the first rotating member;

[0009] a locking member, the locking member having a locked state and a released state. In the locked state, the locking member connects the rotating shaft and the first rotating member, and the rotating shaft and the first rotating member can rotate synchronously; in the released state, the first rotating member rotates relative to the rotating shaft;

[0010] a damping member rotatably connected to the rotating shaft, and capable of providing reverse resistance when the rotating shaft rotates relative to the damping member;

[0011] Wherein, the first rotating member has a first rotation direction and a second rotation direction that are opposite. When the first rotating member rotates along the first rotation direction, the locking member switches to a disengaged state so that the first rotating member rotates without damping relative to the damping member; when the first rotating member rotates along the second rotation direction, the locking member switches to a locked state so that the first rotating member rotates with damping relative to the damping member.

[0012] The one-way damper according to the embodiments of the present invention has at least the following beneficial effects: The one-way damper of this embodiment can achieve a unidirectional damping effect, but has no damping effect during reverse rotation. When the first rotating member rotates in the first direction, it is not affected by the damping effect, allowing for rapid and effortless rotation. When the first rotating member rotates in the second direction, it is affected by the damping effect, limiting and buffering the rotational speed.

[0013] According to some embodiments of the present invention, the locking member is a torsion spring, which is sleeved on either the rotating shaft or the first rotating member and connected to the other one, and the rotation direction of the torsion spring is the same as the first rotation direction.

[0015] According to some embodiments of the present invention, the torsion spring further has an initial state. In the initial state, the torsion spring is sleeved on the rotating shaft and has a friction force F1. The rotating shaft has a damping force F2 relative to the damping member, and the friction force F1 is smaller than the damping force F2.

[0016] When the first rotating member rotates along the first rotation direction, the torsion spring gradually expands and the friction force F1 gradually decreases, so that the first rotating member rotates relative to the rotating shaft; when the first rotating member rotates along the second rotation direction, the torsion spring gradually contracts and the friction force F1 gradually increases until it is greater than or equal to the damping force F2, so that the first rotating member drives the rotating shaft to rotate synchronously.

[0017] According to some embodiments of the present invention, one axial end of the first accommodating cavity has a first opening for inserting the rotating shaft, and the mounting groove extends axially and penetrates to the end surface where the first opening is located.

[0019] According to some embodiments of the present invention, the one-way damper further includes an adjusting member, the damping member defines a second accommodating chamber, the second accommodating chamber having a first through hole for inserting the rotating shaft and a second through hole for inserting the adjusting member, and the second accommodating chamber is filled with damping oil;

[0020] The adjusting member is capable of adjusting the viscosity of the damping oil in the second accommodating chamber, so as to adjust the magnitude of the resistance when the rotating shaft rotates relative to the damping member.

[0021] According to some embodiments of the present invention, the adjusting member is threadedly connected to the damping member, and the adjusting member can be screwed into or out of the damping member to adjust the volume of the second accommodating chamber for accommodating the damping oil.

[0022] According to some embodiments of the present invention, the rotating shaft includes a first shaft portion and a first ring portion sleeved on the first shaft portion, the first shaft portion and the first ring portion define an annular third accommodating chamber, the adjusting member has a fourth accommodating chamber, the adjusting member can be inserted into the third accommodating chamber, the end face of the adjusting member and the cavity wall of the third accommodating chamber define a first oil chamber, and the first shaft portion is inserted into the fourth accommodating chamber, the end face of the first shaft portion and the cavity wall of the fourth accommodating chamber define a second oil chamber.

[0023] According to some embodiments of the present invention, a first step surface is provided on the first shaft portion, and a second step surface is correspondingly provided on the inner wall of the fourth accommodating cavity. The first step surface, the second step surface, the inner wall of the fourth accommodating cavity and the outer wall of the first shaft portion define a third oil cavity.

[0024] A toilet according to a second embodiment of the present invention comprises:

[0025] Toilet body;

[0026] A toilet cover, the toilet cover having a closing direction and an opening direction relative to the toilet body;

[0029] The toilet according to the embodiments of the present invention has at least the following beneficial effects: In some application scenarios, the second rotation direction is set to be the same as the closing direction of the toilet lid, so that the toilet lid rotates with damping relative to the toilet body when closing, thereby preventing the toilet lid from colliding with the toilet body at a relatively high speed during the closing process due to the effect of the toilet lid's own gravity. In other application scenarios, when the toilet has an automatic flap function, the second rotation direction can also be set to be the same as the opening direction of the toilet lid, so that the toilet lid rotates with damping relative to the toilet body when opening, thereby preventing the toilet lid from colliding with the toilet body at an excessively high flap speed when driven by the motor, causing damage.

[0042] In the description of the present invention, reference to terms such as "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the exemplary expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0043] like Figures 1 to 3As shown, the first embodiment of the present application provides a one-way damper, which includes a first rotating member 100, a rotating shaft 200, a locking member 300, and a damping member 400. One of the first rotating member 100 and the damping member 400 is disposed on the toilet body, and the other is disposed on the toilet lid. One end of the rotating shaft 200 is rotatably connected to the first rotating member 100, and the other end is rotatably connected to the damping member 400. When the rotating shaft 200 rotates relative to the damping member 400, the damping member 400 can provide reverse resistance to damp the rotation of the rotating shaft 200 relative to the damping member 400.

[0044] The rotating shaft 200 is connected to the first rotating member 100 via a locking member 300. The locking member 300 has a locked state and a disengaged state. In the locked state, the locking member 300 connects the rotating shaft 200 and the first rotating member 100, so that the rotation of the first rotating member 100 can drive the synchronous rotation of the rotating shaft 200. As a result, the user can feel the resistance generated by the damping member 400 when rotating the first rotating member 100. In the disengaged state, the first rotating member 100 is movably connected to the rotating shaft 200. The first rotating member 100 can rotate relative to the rotating shaft 200, while the rotating shaft 200 does not rotate. As a result, the rotation of the first rotating member 100 is not affected by the resistance generated by the damping member 400.

[0045] The first rotating member 100 has a first rotation direction and a second rotation direction that are opposite. When the first rotating member 100 rotates along the first rotation direction, the locking member 300 switches to a disengaged state so that the first rotating member 100 rotates without damping relative to the damping member 400; when the first rotating member 100 rotates along the second rotation direction, the locking member 300 switches to a locked state so that the first rotating member 100 rotates with damping relative to the damping member 400.

[0046] The locking member 300 can be a ratchet pawl structure. When the first rotating member 100 rotates in a set direction, the rotating shaft 200 does not rotate with the first rotating member 100. When the first rotating member 100 rotates in the opposite direction of the set direction, the first rotating member 100 drives the rotating shaft 200 to rotate synchronously. The locking member 300 can also be an elastic protrusion structure. For example, an elastic protrusion structure is provided on the end face of the rotating shaft 200. The protrusion can extend or retract in the radial direction of the rotating shaft 200. The inner wall of the first rotating member 100 is provided with a plurality of protruding teeth. One side of the protruding teeth is an inclined surface, and the other side is a cross-section. Therefore, when the first rotating member 100 rotates in the set direction, the protrusions elastically abut the inclined surfaces of each protruding tooth in turn, and the rotating shaft 200 does not rotate with the first rotating member 100. When the first rotating member 100 rotates in the opposite direction of the set direction, the protrusion abuts against the cross section of one of the protruding teeth. The rotation of the first rotating member 100 can drive the rotating shaft 200 to rotate synchronously, thereby causing the rotation of the first rotating member 100 to be subject to resistance.

[0047] In some embodiments, the locking member 300 may also be a torsion spring 310, which is sleeved on either the rotating shaft 200 or the first rotating member 100 and connected to the other. When the rotating shaft 200 and the first rotating member 100 rotate relative to each other, the torsion spring 310 is subjected to circumferential torque and thus contracts or expands. Specifically, the torsion spring 310 has a rotation direction. It should be explained that, for example, Figure 4 As shown, the torsion spring 310 is provided with a connecting portion 311 for connecting to the rotating shaft 200 or the first rotating member 100. The connecting portion 311 extends radially outward along the torsion spring 310. The end provided with the connecting portion 311 is set as the head end and the other end is set as the tail end. The rotation direction of the torsion spring 310 is defined as the twisting direction from the head end to the tail end along the solid part of the torsion spring 310.

[0048] The rotation direction of the torsion spring 310 is configured to be the same as the first rotation direction and opposite to the second rotation direction. Furthermore, when the first rotating member 100 rotates in the first rotation direction, the torsion spring 310 gradually expands, switches to a disengaged state, and the first rotating member 100 rotates relative to the rotating shaft 200. When the first rotating member 100 rotates in the second rotation direction, the torsion spring 310 gradually contracts, switches to a locked state, and the first rotating member 100 drives the rotating shaft 200 to rotate via the torsion spring 310, thereby achieving a damped rotational connection between the first rotating member 100 and the damping member 400. The following description uses the case where the torsion spring 310 is sleeved on the rotating shaft 200 and the case where the torsion spring 310 is sleeved on the first rotating member 100 as examples.

[0049] In some embodiments, as Figure 2 As shown, the first rotating member 100 is defined by a first accommodating chamber 110, one end of the rotating shaft 200 is inserted into the first accommodating chamber 110, and the other end is connected to the damping member 400. The end of the rotating shaft 200 inserted into the first accommodating chamber 110 is set as the first end, and the end connected to the damping member 400 is set as the second end. The torsion spring 310 is sleeved on the first end of the rotating shaft 200 and inserted into the first accommodating chamber 110 along with the first end of the rotating shaft 200. One end of the torsion spring 310 extends radially toward the cavity wall of the first accommodating chamber 110 to form a connecting portion 311. A mounting groove 111 is provided on the inner wall of the first accommodating chamber 110, and the connecting portion 311 can be inserted into the mounting groove 111.

[0050] When the first rotating member 100 rotates along the first rotation direction, the torsion spring 310 gradually expands, the inner diameter of the torsion spring 310 increases, and the torsion spring 310 switches to a separated state. The torsion spring 310 and the rotating shaft 200 are movably connected, and the torsion spring 310 does not generate a tightening force on the rotating shaft 200. The rotation of the first rotating member 100 drives the torsion spring 310 to rotate, but the rotating shaft 200 remains relatively stationary, and thus the first rotating member 100 rotates without damping relative to the damping member 400. When the first rotating member 100 rotates along the second rotation direction, the torsion spring 310 gradually contracts, the inner diameter of the torsion spring 310 decreases, and the torsion spring 310 switches to a locked state. The torsion spring 310 generates a tightening force on the rotating shaft 200, so that the torsion spring 310 and the rotating shaft 200 are locked and connected to form an integrated structure. The torque of the first rotating member 100 is transmitted to the rotating shaft 200 through the torsion spring 310 to drive the rotating shaft 200 to rotate. Since there is a damping effect when the rotating shaft 200 rotates relative to the damping member 400, the first rotating member 100 rotates relative to the damping member 400 with damping.

[0051] Furthermore, the torsion spring 310 has an initial state. In the initial state, the torsion spring 310 is sleeved on the rotating shaft 200, and a predetermined friction force F1 is present between the torsion spring 310 and the rotating shaft 200, so that the torsion spring 310 is clamped tightly against the rotating shaft 200 in the initial state. The rotating shaft 200 exerts a damping force F2 relative to the damping member 400. The friction force F1 is smaller than the damping force F2.

[0052] When the first rotating member 100 rotates in the first rotational direction, the torsion spring 310 gradually expands, and the friction force F1 between the torsion spring 310 and the rotating shaft 200 gradually decreases, causing the rotating member to rotate relative to the rotating shaft 200. It should be noted that because the friction force F1 is initially less than the damping force F2, the rotating shaft 200 does not rotate when the first rotating member 100 rotates in the first rotational direction. When the first rotating member 100 rotates in the second rotational direction, the torsion spring 310 gradually contracts, and the friction force F1 between the torsion spring 310 and the rotating shaft 200 gradually increases until the friction force F1 is greater than or equal to the damping force F2. At this point, the rotating shaft 200 is driven to rotate by the friction force F1. In this case, the rotating shaft 200 rotates only when the first rotating member 100 rotates in the second rotational direction, resulting in a significant one-way damping effect.

[0053] Correspondingly, in other embodiments, the initial friction force F1 is greater than the damping force F2. Thus, when the first rotating member 100 rotates in the first rotational direction, the first rotating member 100 can initially drive the rotating shaft 200 to rotate slightly until the friction force F1 decreases to less than or equal to the damping force F2, at which point the first rotating member 100 rotates relative to the rotating shaft 200. When the first rotating member 100 rotates in the second rotational direction, the first rotating member 100 can directly drive the rotating shaft 200 to rotate, resulting in a faster damping response speed.

[0054] Further, such as Figure 3 As shown, the first accommodating chamber 110 has a first opening at one axial end for inserting the rotating shaft 200. A mounting groove 111 extends axially along the inner wall of the first accommodating chamber 110 and penetrates to the end surface where the first opening is located. Furthermore, during assembly, the rotating shaft 200 and the torsion spring 310 mounted on the rotating shaft 200 can be quickly installed into the first accommodating chamber 110 by aligning the connecting portion 311 with the mounting groove 111. This makes insertion and removal of the first rotating member 100 and the rotating shaft 200 relatively easy.

[0055] In other embodiments, a first accommodating cavity 110 is provided at one end of the rotating shaft 200, the first rotating member 100 is inserted into the first accommodating cavity 110, and a torsion spring 310 is sleeved on the first rotating member 100 and inserted into the first accommodating cavity 110 along with the first rotating member 100. One end of the torsion spring 310 extends radially toward the cavity wall of the first accommodating cavity 110 to form a connecting portion 311. A mounting groove 111 is provided on the interior of the first accommodating cavity 110, and the connecting portion 311 can be inserted into the mounting groove 111.

[0056] When the first rotating member 100 rotates along the first rotation direction, the torsion spring 310 gradually expands, the inner diameter of the torsion spring 310 increases, and the torsion spring 310 switches to a separated state. The first rotating member 100 and the torsion spring 310 are movably connected, and the torsion spring 310 does not generate a tightening force on the first rotating member 100. The rotation of the first rotating member 100 cannot drive the torsion spring 310 and the rotating shaft 200 to rotate, and thus the first rotating member 100 rotates without damping relative to the damping member 400. When the first rotating member 100 rotates along the second rotation direction, the torsion spring 310 gradually contracts, the inner diameter of the torsion spring 310 decreases, and the torsion spring 310 switches to a locked state. The torsion spring 310 generates a tightening force on the rotating shaft 200, so that the torsion spring 310 and the first rotating member 100 are locked and connected to form an integrated structure. The torque of the first rotating member 100 is transmitted to the rotating shaft 200 through the torsion spring 310 to drive the rotating shaft 200 to rotate. Since there is a damping effect when the rotating shaft 200 rotates relative to the damping member 400, the first rotating member 100 rotates with damping relative to the damping member 400.

[0057] In some embodiments, the damping element 400 can achieve rotational damping through a friction plate structure, or achieve a damping effect through the low-speed flow of damping oil. In other embodiments, the damping oil of the one-way damper has good viscosity and can adhere to the rotating shaft 200 to hinder the rotation of the rotating shaft 200 to achieve a damping effect. Specifically, Figure 2 and Figure 3As shown, the damping member 400 defines a second accommodating chamber 410, which has a first through-hole 411 for inserting the rotating shaft 200. The second accommodating chamber 410 is filled with damping oil. Furthermore, the rotating shaft 200 located in the second accommodating chamber 410 is wrapped in the damping oil, and the viscous force of the damping oil acts on the rotating shaft 200 during rotation, producing a damping effect. The one-way damper also includes an adjustment member 500. The second accommodating chamber 410 also has a second through-hole 412 for inserting the adjustment member 500. The adjustment member 500 can adjust the viscosity of the damping oil in the second accommodating chamber 410 to adjust the amount of resistance when the rotating shaft 200 rotates relative to the damping member 400.

[0058] In the prior art, when the shaft core rotates, it drives the blades to squeeze the damping oil, and the damping oil flows from the hole or groove to another chamber. In the initial state, there is less damping oil in the hole or groove, so the damping oil can move through the hole or groove to the other chamber at a relatively fast speed. At this time, the damping force is relatively small. As the damping oil in the hole or groove increases, the damping force gradually increases. After the hole or groove is filled with damping oil, the amount of oil remains constant, so that the damping force remains constant. Taking the use of this damper in the process of opening the toilet lid as an example, in the first half of the toilet lid opening process, the resistance of the damper is relatively small, and the toilet lid opens quickly. When the hole or groove connecting the two chambers is filled, the resistance of the damper is relatively large, and the toilet lid opens slowly, which causes the user to experience a noticeable sense of frustration when opening the toilet lid.

[0059] In this embodiment, the damping member 400 achieves damping through the viscosity of the damping oil, so the damping force is consistent when rotating at any angle. The shaft 200 can rotate 360 degrees relative to the damping member 400. Under the action of the damping oil, no matter how the rotation angle of the shaft 200 relative to the damping member 400 changes, the damping oil can play a role in damping the rotation of the shaft 200. Compared with the existing damper in which the shaft core drives the blades to squeeze the damping oil to move to achieve the damping effect when rotating, the damping force and resistance speed of the damping member 400 in this embodiment are relatively consistent, and the phenomenon of unstable damping effect will not occur. Applying this one-way damper to the opening and closing process of the toilet lid can make the opening and closing process of the toilet lid smoother and provide a better user experience.

[0060] There are many ways for the adjusting member 500 to adjust the viscosity of the damping oil. For example, by adding more damping oil within a certain volume to increase the oil pressure of the damping oil, the viscosity of the damping oil is higher and the damping effect is better. Alternatively, the adjusting member 500 can change the volume of the chamber that contains the damping oil, and by reducing the volume of the chamber to increase the oil pressure of the damping oil, a better damping effect is obtained. In some embodiments, the adjusting member 500 is threadedly connected to the damping member 400, and the adjusting member 500 can be screwed out or screwed into the damping member 400, that is, the adjusting member 500 can change the volume of the adjusting member 500 inserted into the second accommodating chamber 410 by rotating, thereby adjusting the volume of the second accommodating chamber 410 for accommodating the damping oil.

[0061] Furthermore, the adjusting member 500 cooperates with the rotating shaft 200 to separate a plurality of oil chambers. The rotating shaft 200 includes a first shaft portion 210 and a first ring portion 220 sleeved on the first shaft portion 210. The first shaft portion 210 and the first ring portion 220 define an annular third accommodating chamber 230. The adjusting member 500 has an axially extending fourth accommodating chamber 510. The adjusting member 500 can be inserted into the third accommodating chamber 230. The end surface of the adjusting member 500 and the wall of the third accommodating chamber 230 define a first oil chamber 240. The first shaft portion 210 is inserted into the fourth accommodating chamber 510. The end surface of the first shaft portion 210 and the wall of the fourth accommodating chamber 510 define a second oil chamber 250. In addition, a first step surface 211 is provided on the first shaft portion 210, and a second step surface 511 is correspondingly provided on the inner wall of the fourth accommodating chamber 510. The first step surface 211, the second step surface 511, the inner wall of the fourth accommodating chamber 510 and the outer wall of the first shaft portion 210 define a third oil chamber 260.

[0062] When the adjusting member 500 is screwed in axially, the volumes of the first, second, and third oil chambers 240, 250, and 260 decrease, increasing the viscosity of the damping oil therein and providing a better damping effect, making it suitable for damping and cushioning heavier toilet lids. When the adjusting member 500 is screwed out axially, the volumes of the first, second, and third oil chambers 240, 250, and 260 increase, decreasing the viscosity of the damping oil therein and providing a relatively less pronounced damping effect, making it suitable for damping and cushioning lighter toilet lids.

[0063] Based on the above, the one-way damper of the present application can achieve a one-way damping effect, and has no damping effect when rotating in the reverse direction. When the first rotating member 100 rotates in the first direction, it is not affected by the damping effect, allowing for fast and effortless rotation. When the first rotating member 100 rotates in the second direction, it is affected by the damping effect, which can limit and buffer the rotation speed.

[0064] An embodiment of the second aspect of the present application also proposes a toilet, comprising a toilet body, a toilet cover and the one-way damper mentioned in any of the above embodiments, wherein the first rotating member 100 is connected to the toilet cover, and the damping member 400 is connected to the toilet body so that the toilet body and the toilet cover are rotatably connected.

[0065] In some application scenarios, the second rotation direction is set to be the same as the closing direction of the toilet lid, so that the toilet lid rotates with damping relative to the toilet body when closing, avoiding the toilet lid colliding with the toilet body at a relatively high speed during the closing process due to the effect of the toilet lid's own gravity. In other application scenarios, when the toilet has an automatic flap function, the second rotation direction can also be set to be the same as the opening direction of the toilet lid, so that the toilet lid rotates with damping relative to the toilet body when opening, avoiding the toilet lid's flap speed being too fast when driven by the motor and hitting the toilet body and causing damage.

[0066] While the embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to the embodiments described above. Various modifications may be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof may be combined with one another unless there is a conflict.
