[0007] According to the button assembly of the embodiment of the present invention, there are at least the following beneficial effects: when the user rotates the button body, the button body will drive the rotating shaft to rotate, and the rotating shaft will synchronously drive the trigger member to rotate, so that the trigger member gradually compresses the elastic member, allowing the trigger member to switch from the first position to the second position. When the trigger member is in the second position, the trigger member abuts against the switch member, thereby triggering the flushing function, and the toilet starts to flush. Since the maximum distance between the button body and the axis of the rotating shaft is greater than the maximum distance from the center line of the elastic member to the axis of the rotating shaft, according to the lever principle, it is equivalent to the force arm between the button body and the rotating shaft being greater than the force arm between the trigger member and the rotating shaft.

[0038] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0039] Reference Figure 1 and Figure 2 As shown, a key assembly 1000 provided by an embodiment of the present invention includes a rotating shaft 100, a key body 200, a trigger member 300, an elastic member 400 and a switch member 500. Along the axial direction of the rotating shaft 100, the key body 200 is fixedly connected to one side of the rotating shaft 100, and the trigger member 300 is fixedly connected to the other side of the rotating shaft 100. The key body 200 and the trigger member 300 are both extended in a direction perpendicular to the axial direction of the rotating shaft 100. The key body 200 and the trigger member 300 can be parallel to each other or at an angle to each other. When the key body 200 and the trigger member 300 are parallel to each other, the length of the key body 200 in the front-to-back direction is greater than the length of the trigger member 300 in the front-to-back direction. When along Figure 1 When the button body 200 is rotated in the rotation direction, the button body 200 drives the rotating shaft 100 and the trigger member 300 to rotate synchronously.

[0040] The button assembly 1000 of this embodiment is mainly used in toilets and is used to realize the flushing function. The trigger member 300 has a first position and a second position. When the button assembly 1000 is in the first position, the trigger member 300 does not contact the switch member 500 and does not trigger the flushing function. The first position can be understood as the initial position; when the button assembly 1000 is in the second position, the trigger member 300 contacts the switch member 500 and triggers the flushing function. The second position can be understood as the trigger position. The elastic member 400 is used to apply elastic force to the trigger member 300, so that the trigger member 300 can be reset from the second position to the first position. When the user needs to flush, he can rotate the button body 200. The button body 200 drives the rotating shaft 100 and the trigger member 300 to rotate around the axis of the rotating shaft 100. The trigger member 300 rotates from the first position to the second position, allowing the trigger member 300 to contact the switch member 500, thereby triggering the flushing function. When the user releases the button body 200, the trigger member 300 can automatically reset to the first position under the action of the elastic member 400.

[0041] It is understandable that the user needs to overcome the elastic force of the elastic member 400 to press the button body 200. In order to achieve a labor-saving effect, the present embodiment designs a lever structure. Figure 4 As shown, along the direction perpendicular to the axis X of the rotating shaft 100, the maximum distance between the key body 200 and the axis X is L1, and the maximum distance between the center line of the elastic member 400 and the axis X is L2. It can also be understood that the maximum distance between the contact position between the trigger member 300 and the elastic member 400 and the axis X is L2, and L1 is greater than L2. L1 can be understood as the force arm for the user to apply a pressing force on the key body 200, and L2 can be understood as the force arm for the trigger member 300 to apply a pressing force on the elastic member 400. According to the principle of leverage, the user only needs to apply a pressing force on the key body 200 that is less than the elastic force of the elastic member 400 to overcome the elastic force of the elastic member 400, thereby driving the key body 200 and the trigger member 300 to rotate, allowing the trigger member 300 to contact the switch member 500, and triggering the flush function. This can achieve a labor-saving effect, reduce the pressing force, and improve the hand feel. This form is easier to operate for users with weak hand strength (such as the elderly or children), increasing the convenience of use. Furthermore, the lever-type structure distributes some of the pressing force, reducing the mechanical stress on the key body 200. This reduces wear on the key body 200 over extended use, extending the service life of the key body 200. Furthermore, the lever-type structure allows users to apply force to the key body 200 from multiple positions, providing greater flexibility than the vertical front-facing pressure required by conventional keys. This offers significant advantages, particularly in unusual installation locations or where space is limited.

[0042] In some embodiments, the contact portion between the trigger member 300 and the switch member 500 can be configured as a conductive structure. When the trigger member 300 contacts the switch member 500, the internal circuit is turned on, thereby triggering the flush function. The button assembly 1000 of this embodiment electrically controls the flush function of the toilet.

[0043] In some other embodiments, the trigger member 300 triggers the flushing function by squeezing the switch member 500 .

[0044] In some embodiments, the button body 200 can be designed into various shapes to adapt to different devices and user needs and better integrate with the overall appearance of the product.

[0045] In some embodiments, the elastic member 400 may be configured as an elastic structure such as a spring or a leaf spring. When the elastic member 400 is configured as a spring, the axis of the elastic member 400 is the center line of the elastic member 400 .

[0046] Reference Figure 1 and Figure 2 As shown, in some embodiments, along the axial direction of the rotating shaft 100, an appearance part 600 is provided between the button body 200 and the trigger part 300, the button body 200 is located on the left side of the appearance part 600, and the trigger part 300 is located on the right side of the appearance part 600. The appearance part 600 can be understood as the shell structure of the smart cover of the toilet. The appearance part 600 is provided with a through hole 630, and the rotating shaft 100 is passed through the through hole 630. The rotating shaft 100 can rotate relative to the appearance part 600. The appearance part 600 separates the button body 200 from the trigger part 300. The button body 200 is exposed to the outside and the trigger part 300 is hidden inside, which can improve the appearance effect.

[0047] In some embodiments, reference Figure 3 As shown, the button assembly 1000 also includes a limiting member 610, and the elastic member 400 is located on one side of the trigger member 300. The limiting member 610 is located on the side of the trigger member 300 away from the elastic member 400. It can also be understood that the elastic member 400 and the limiting member 610 are respectively located on two sides of the trigger member 300 away from each other. When the trigger member 300 is in the first position, the elastic member 400 is compressed, and the elastic member 400 generates an elastic force. The elastic force of the elastic member 400 acts on the trigger member 300, so that the trigger member 300 abuts against the limiting member 610. The limiting member 610 can limit the trigger member 300 from rotating in the direction away from the elastic member 400, so that the trigger member 300 remains in the first position, and plays a limiting role on the trigger member 300. It can be understood that the trigger member 300 keeps pressing the elastic member 400, and the elastic member 400 and the limiting member 610 press against the trigger member 300, so that the trigger member 300 is not easy to loosen in the first position. It should be noted that, referring to Figure 4 、 Figure 8 and Figure 9 As shown, Figure 4 and Figure 8 , the trigger member 300 is in the first position, Figure 9 In the middle, the trigger member 300 is in the second position. In the front-to-back direction, the length of the limiting member 610 is less than the length of the trigger member 300, and a certain amount of space is left behind the limiting member 610 to avoid blocking the rear side of the trigger member 300. This arrangement can prevent the limiting member 610 from being blocked from rotating from the first position to the second position.

[0048] In some embodiments, reference Figure 3 and Figure 8 As shown, the key assembly 1000 further includes a support member 620, which is located on the side of the trigger member 300 facing away from the stop member 610. The elastic member 400 is located between the support member 620 and the trigger member 300. It can also be understood that the stop member 610, the trigger member 300, the elastic member 400, and the support member 620 are arranged in sequence along the circumference of the rotating shaft 100. The support member 620 is used to provide support for the elastic member 400. One end of the elastic member 400 abuts the trigger member 300, and the other end of the elastic member 400 abuts the support member 620, thereby clamping the elastic member 400 and allowing the elastic member 400 to provide elastic force. In some embodiments, the support member 620 and the stop member 610 are both connected to the side of the appearance member 600 near the trigger member 300. The support member 620 and the stop member 610 are constructed as a platform structure with a simple shape and easy processing and manufacturing.

[0049] In some embodiments, the flushing function can be triggered when the user presses the button body 200 downward, or when the user pushes the button body 200 upward, and the position of the elastic member 300 relative to the trigger member 300 can be set accordingly.

[0050] In some embodiments, reference Figure 6 As shown, the limit member 610 is located above the trigger member 300, and the support member 620 is located below the trigger member 300. When the trigger member 300 is in the first position, the upper end of the trigger member 300 abuts the limit member 610. The elastic member 400 is located below the trigger member 300, with the upper end of the elastic member 400 abutting the lower end of the trigger member 300, and the lower end of the elastic member 400 abutting the support member 620. Alternatively, the upper end of the elastic member 400 is fixedly connected to the lower end of the trigger member 300, and the lower end of the elastic member 400 is fixedly connected to the support member 620, thereby securing the elastic member 400. In this case, when the user presses down on the button body 200, the trigger member 300 compresses the elastic member 400 and contacts the switch member 500, thereby triggering the flush function.

[0051] In other embodiments, the limit member 610 may be located below the trigger member 300, and the support member 620 may be located above the trigger member 300. When the trigger member 300 is in the first position, the lower end of the trigger member 300 abuts the limit member 610. The elastic member 400 is located above the trigger member 300, with the lower end of the elastic member 400 abutting the upper end of the trigger member 300, and the upper end of the elastic member 400 abutting the support member 620. Alternatively, the lower end of the elastic member 400 is fixedly connected to the upper end of the trigger member 300, and the upper end of the elastic member 400 is fixedly connected to the support member 620, thereby securing the elastic member 400. In this case, when the user pushes the button body 200 upward, the trigger member 300 compresses the elastic member 400 and contacts the switch member 500, thereby triggering the flush function.

[0052] In some embodiments, reference Figure 4 As shown, the button body 200 and the trigger member 300 are parallel to each other, and the button body 200 includes a pressing portion 210. The user drives the button body 200 to rotate by pressing the pressing portion 210. Along the axial direction perpendicular to the rotating shaft 100, the pressing portion 210 and the elastic member 400 are located on the same side of the rotating shaft 100. It can be understood that the L1 force arm of the button body 200 and the L2 force arm of the trigger member 300 are located on the same side of the rotating shaft 100. Such an arrangement can make the main structures of the button body 200 and the trigger member 300 extend toward the same side. The button body 200 and the trigger member 300 overlap with each other in the front-to-back direction, which can reduce the space occupied by the button assembly 1000 in the front-to-back direction, which is conducive to the miniaturization of the button assembly 1000.

[0053] Reference Figure 5 As shown, in some other embodiments, along the axial direction perpendicular to the rotating shaft 100, the pressing portion 210 and the elastic member 400 can be respectively located on both sides of the rotating shaft 100, that is, the L1 lever arm of the button body 200 and the L2 lever arm of the trigger member 300 are respectively located on both sides of the rotating shaft 100.

[0054] In some embodiments, reference Figure 8 and Figure 9 As shown, a clearance groove 310 is provided on the side of the trigger member 300 close to the elastic member 400. At least part of the structure of the elastic member 400 is located in the clearance groove 310. The elastic member 400 abuts against the inner wall of the clearance groove 310. After the clearance groove 310 is provided, it is equivalent to reserving a storage space for accommodating the elastic member 400. The overall space occupied by the trigger member 300 and the elastic member 400 can be reduced in the up and down directions, which is conducive to the miniaturization of the internal structure of the button assembly 1000.

[0055] In some embodiments, the elastic member 400 is located below the trigger member 300, and at least part of the switch member 500 is located below the trigger member 300. When the user rotates the button body 200, the button body 200 drives the trigger member 300 to swing downward, contacting the switch member 500 below, triggering the flush function. It is understood that with this arrangement, if the user applies a strong pressing force to the button body 200, this pressing force will also be directly applied to the switch member 500, affecting its structure.

[0056] Based on this, refer to Figure 3 and Figure 6 As shown, in some embodiments, along the axial direction of the rotating shaft 100, the switch member 500 and the trigger member 300 are arranged opposite to each other, and the trigger member 300 is provided with an inclined surface 320 on the side close to the switch member 500, and the switch member 500 is provided with a convex portion 510 on the side close to the trigger member 300. The side of the trigger member 300 close to the elastic member 400 is defined as the first side, and the side of the trigger member 300 away from the elastic member 400 is defined as the second side. At the position of the inclined surface 320 corresponding to the convex portion 510, the distance between the inclined surface 320 and the convex portion 510 along the axial direction of the rotating shaft 100 gradually decreases from the first side to the second side. It can also be understood that the distance between the inclined surface 320 and the convex portion 510 gradually decreases from bottom to top. When the trigger member 300 rotates from the first position to the second position, the inclined surface 320 will gradually approach the convex portion 510. As shown Figure 6 When the trigger member 300 is in the first position, the inclined surface 320 does not contact the convex portion 510, and there is a gap between the inclined surface 320 and the convex portion 510. Figure 7 When the trigger member 300 is in the second position, the inclined surface 320 abuts the protrusion 510, thereby triggering the flush function. At this point, the protrusion 510 blocks the trigger member 300, preventing it from rotating further downward and limiting its position. This arrangement converts the circumferential force exerted by the button body 200 on the trigger member 300 into an axial force exerted by the trigger member 300 on the protrusion 510 along the rotating shaft 100. This reduces the direct force exerted by the trigger member 300 on the switch member 500, protects the switch member 500 structure, and prevents the switch member 500 from breaking due to excessive force.

[0057] In some embodiments, the inclined surface 320 of the trigger member 300 can trigger the flushing function by squeezing the protrusion 510 .

[0058] Reference Figure 6As shown, in some embodiments, the protrusion 510 can be configured as a hemispherical structure, with the surface of the protrusion 510 being configured as an outwardly convex spherical surface. The protrusion 510 abuts the inclined surface 320 via the spherical surface. It can be understood that the inclined surface 320 and the protrusion 510 are in point contact, with a small contact area. This can reduce the friction between the protrusion 510 and the inclined surface 320, resulting in low damping and no jamming, which helps the trigger member 300 smoothly return to the first position. Without limitation, the protrusion 510 can also be configured as other irregular shapes, and the spherical surface can be a curved surface of other shapes.

[0059] Reference Figure 8 As shown, in some embodiments, a boss structure can be provided on the side of the trigger member 300 close to the switch member 500, and then the above-mentioned inclined surface 320 can be processed on the boss structure, so that the inclined surface 320 can be closer to the protrusion 510 of the switch member 500, thereby reducing the rotational stroke of the trigger member 300 and making it easier for users to operate the button body 200.

[0060] In some embodiments, reference Figure 1 As shown, the button body 200 is configured as a flat structure, which can be understood as the length of the button body 200 in the front-to-back direction being greater than the height of the button body 200 in the up-down direction. Specifically, the button body 200 is a rectangular parallelepiped structure. An identification portion is provided on the top of the button body 200, and the identification portion includes a silk-screen pattern. When the trigger member 300 is in the first position, the button body 200 is in a horizontal state, so that the identification portion faces the user, making it convenient for the user to quickly observe the identification portion and identify the control function of the button assembly 1000. In some other embodiments, the identification portion may include a luminous pattern or a raised texture structure, which is convenient for naked eye observation or finger touch identification. The operation method conforms to the user's usage habits, and the appearance is combined with the function icon indication to reduce the user's learning and use costs. In addition, the flat structure allows users to more easily identify the button assembly 1000 that controls the flushing function, and is less likely to cause misoperation.

[0061] The embodiment of the present utility model further provides a flushing device, comprising the button assembly 1000 of the above embodiment. The flushing device is applied to a toilet and is mainly used to realize the flushing function.

[0062] The present invention also provides a toilet, which includes the flushing device of the above embodiment, and thus has the above technical effects, which will not be described in detail here. The toilet can be understood as a product such as an ordinary toilet or a smart toilet.

[0063] In some embodiments, the toilet also includes a water tank, and the flushing device is used to drive the driving mechanism of the flushing to be arranged in the water tank. When the user presses the button body 200, the trigger member 300 rotates to the second position and abuts against the switch member 500, thereby turning on the circuit and controlling the driving mechanism in the water tank to realize the flushing function.
