Description

Technical Field

[0001] This utility model specifically relates to a toilet flushing tank press panel structure. Background Technology

[0002] As modern bathroom products develop towards intelligence, humanization, and aesthetics, the operating mechanism of toilet tanks not only needs to have good functionality, but also needs to take into account operational comfort, aesthetic design, and long-term reliability.

[0003] Currently, most common toilet tanks use a top-press flush valve structure, where users trigger the flush by pressing a button or panel on top of the tank. Traditional press-button designs typically involve a vertically sliding button, either independently mounted on or embedded in the panel, leaving noticeable structural gaps between it and the surrounding panel. This design not only results in a fragmented overall appearance and a lack of aesthetic unity, but also makes it easier for dust, limescale, and bacteria to accumulate in the gaps, making cleaning difficult and affecting the hygiene of the bathroom environment. Furthermore, because the button is a point-like or small-area press structure, users must apply precise force to the center of the button to effectively trigger the flush. The operating area is small, with a low margin for error, making it inconvenient to use, especially with wet hands or in poor visibility. In addition, these buttons are directly connected to the internal drain valve's opening and closing mechanism. The drain valve's sealing components (such as rubber diaphragms) have a certain pre-tightening force and frictional resistance when stationary, resulting in significant initial damping that must be overcome when pressing, making the operation feel heavy and potentially causing fatigue with prolonged use. Furthermore, what is even more prominent is that these buttons have a small pressing area, high hardness, and slightly protruding edges. When pressing them, you need to press down with your fingertips, which can easily cause scratches, cracks, or even breakage to the carefully maintained manicures of female users (such as gel nails, extension nails, etc.). This has become a common problem in daily use, affecting user experience and product friendliness.

[0004] This utility model was developed precisely because of the aforementioned shortcomings. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a toilet tank press panel structure that improves convenience and comfort.

[0006] This utility model is achieved through the following technical solution:

[0007] This utility model provides a toilet tank push-button panel structure. The toilet tank includes a tank body and a push-button valve disposed within the tank body. The push-button panel structure includes a panel bracket connected to the top of the tank body. The top of the panel bracket has an installation cavity groove. At least two push-button components are provided in the installation cavity groove. The two push-button components are rotatably connected to the panel bracket at their ends away from each other, and can swing up and down at their ends close to each other to achieve a push-button operation. The panel bracket is also connected to trigger components that correspond one-to-one with the push-button components. The trigger components are slidably connected to the panel bracket in the vertical direction, with their upper ends abutting against the push-button components and their lower ends abutting against the push-button valve. The installation cavity groove also provides a reset elastic component. The lower end of the reset elastic component abuts against the panel bracket, and its upper end abuts against the trigger components or push-button components to achieve elastic reset.

[0008] As described above, the toilet tank push panel structure has a flat first top surface area on the top of the push member, which covers the edge of the panel support.

[0009] As described above, the flush tank push panel structure has a second top surface area located on one side of the mounting cavity, and the first top surface area and the second top surface area are spliced ​​together to form a complete top surface.

[0010] As described above, the toilet tank push panel structure has a push area at the bottom of the mounting cavity and flat areas on both sides of the push area. The bottom of the push area has a V-shaped structure with a lower middle and higher sides. The pivot of the push member that is rotatably connected to the panel bracket is located at the end of the push area near the flat area.

[0011] As described above, the toilet tank push panel structure has a slot hole on the panel support and a shaft in the slot hole. The push member has a plug plate that is inserted into the slot hole. The plug plate has a guide channel for the shaft to be engaged when it is inserted into the slot hole, and a shaft hole that communicates with the guide channel and can be fitted onto the shaft.

[0012] As described above, the toilet tank push panel structure has an anti-detachment structure between the push member and the panel support to prevent the push member from swinging upward and thus prevent the push member from falling out.

[0013] As described above, the toilet tank push panel structure includes an anti-detachment structure comprising a limiting support plate disposed on the push member and inserted into a slot hole, the panel bracket having an anti-detachment protrusion on one side of the slot hole, and the limiting support plate having a buckle portion that abuts against the anti-detachment protrusion when the push member swings upward.

[0014] As described above, the toilet tank push panel structure has a limiting structure between the panel support and the push member to restrict the swing angle of the push member.

[0015] As described above, the toilet tank push-button panel structure includes a limiting groove on the push-button and a limiting boss on the panel bracket that is inserted into the limiting groove. The limiting groove has an arc-shaped side groove surface for abutting against the limiting boss, and the bottom of the limiting groove is provided with an arc-shaped rib for abutting against the limiting boss. The centers of the arc-shaped side groove surface and the arc-shaped rib are both coincident with the rotation axis of the push-button.

[0016] As described above, the toilet tank push panel structure includes a sliding member and a guide post arranged in parallel with each other. The panel support is provided with a sliding hole for the sliding member to slide through and a guide hole for the guide post to slide through.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. The pressing operation is light and effortless, improving the user experience. It adopts a swing-type pressing component and lever transmission structure, which converts the pressing force into an effective thrust on the trigger component through the rotating shaft. By using the lever principle to amplify the force, it significantly reduces the pressing force required to trigger the pressing water valve. It overcomes the problem of traditional direct-pressure buttons that are difficult to operate due to the large damping of the water valve. It is especially suitable for users such as the elderly and children, improving the comfort of use.

[0019] 2. Large operating area, high fault tolerance, and user-friendly human-computer interaction. The top of the pressing component has a large, flat first top surface area that can rotate around one end, making the entire surface an effective pressing area. The flushing action can be triggered without precisely pressing a specific position. At the same time, the two pressing components are spliced ​​together to form a complete top surface, which also includes large / small flush volume indicators for guidance. The operation is intuitive and convenient, improving the convenience and aesthetic coordination of human-computer interaction, while eliminating hard-to-clean corners and preventing dirt and grime from accumulating.

[0020] 3. High structural integration and stable and reliable operation: The panel bracket integrates functions such as rotational connection, guide sliding, limit anti-detachment, and elastic reset to achieve modular assembly; through the arc-shaped cooperation of the limit groove and the limit boss and the double guide column design, it ensures that the pressing part swings smoothly and the trigger component moves vertically, effectively preventing jamming, tilting or detachment, and ensuring the reliability and durability of long-term use.

[0027] The utility model will be further described below with reference to the accompanying drawings:

[0028] The orientations described in this utility model specification, such as "up," "down," "left," "right," "front," and "back," are based on the orientations in the accompanying drawings and are intended to facilitate the description of the relationships between the various components. They do not indicate the unique or absolute positional relationships between the various components, but are merely one embodiment of the utility model and are not a limitation on its implementation.

[0029] This embodiment introduces a toilet tank push-button panel structure, mainly used on the top panel of toilet tank A. It serves as a cover and a user-operated push-button switch. The toilet tank A includes a tank body A1 and a push-button valve A2 located within the tank body A1. The structure of the push-button valve A2 can refer to the patent solution of the inventor's previously filed patent number CN202220383338.X, entitled "Integrated Valve Body Drain Valve." Figures 1 to 4As shown, this type of toilet tank push panel structure includes a panel bracket 1 connected to the top of the tank body A1. The top of the panel bracket 1 has an installation cavity 10, and at least two push members 2 are provided in the installation cavity 10. The two push members 2 are rotatably connected to the panel bracket 1 at the end away from each other, and can swing up and down at the end close to each other to realize the pressing operation. The panel bracket 1 is also connected to a trigger component 3 corresponding to each push member 2. The trigger component 3 is slidably connected to the panel bracket 1 in the vertical direction, with its upper end abutting against the push member 2 and its lower end abutting against the push button of the push-type water valve A2. When the push member 2 swings down, it pushes the trigger component 3 to slide down and then pushes the push button of the push-type water valve A2 to realize the flushing function. The installation cavity 10 is also provided with a reset elastic member 4. The lower end of the reset elastic member 4 abuts against the panel bracket 1 and the upper end abuts against the trigger component 3 or the push member 2 to realize elastic reset. This structure employs a swing-type pressing component 2, overcoming the drawback of the sliding button requiring damping of the push-button water valve A2, which results in significant pressing resistance. Furthermore, the swing design allows for operation of most of the pressing component 2's surface, greatly increasing the operable area and improving operational comfort and convenience. The core of this pressing panel structure lies in transforming the traditional "vertical pressing" mode into a "lever-type swing" drive mechanism. The two pressing components 2, with the pivot P as the fulcrum, form a lever-like structure. The user applies a downward force near the center end of the pressing component 2, which, through lever amplification, is transmitted to the trigger component 3, thereby driving the water valve A2. Due to the lever principle, even if the water valve button itself has some initial resistance (such as sealing friction), it can be triggered with relatively small pressing force, significantly reducing the required operating force. Simultaneously, this structure decouples the pressing and resetting actions: pressing is performed by the user, while resetting is automatically completed by the resetting elastic component 4, improving the smoothness of use. The low-operating-force design utilizes the lever principle to convert local pressing force into effective trigger displacement, effectively reducing the pressing force required by the user, making it especially suitable for the elderly, children, and other people with less strength. The large operating area coverage, with the pressing component 2 being a large-area flat structure that can be swung, eliminates the need for precise pressing of specific points; the entire first top surface area 21 can serve as an effective operating surface, greatly improving the tolerance and convenience of use. High structural integration: the panel bracket 1 integrates multiple functional structures such as installation, guidance, limiting, and anti-detachment, achieving modular assembly and facilitating production, installation, and subsequent maintenance.

[0030] As a preferred option, such as Figures 1 to 3As shown, the top of the pressing component 2 has a flat first top surface area 21. This first top surface area 21 covers the edge of the panel support 1, meaning the edge of the pressing component 2 extends as far as possible in all directions until it covers the edge of the panel support 1 when projected from top to bottom, thus covering the entire water tank A. This increases the operable area of ​​the top surface of the pressing component 2 and enhances the overall aesthetics of the water tank's top surface. The extended design of the first top surface area 21 not only improves aesthetics but, more importantly, achieves a "seamless coverage" effect. By covering the edge structure of the panel support 1, foreign objects (such as dust and water stains) are prevented from entering the internal mechanism, while also preventing fingers from getting stuck in the gaps and causing safety hazards. This design makes the product appearance closer to an integrated panel, enhancing its premium feel. It improves the simplicity and modernity of the product's appearance, conforming to the minimalist design trend; enhances waterproof and dustproof performance, extending the service life of the internal mechanism; eliminates the problem of dirt accumulating in the gaps at the edge of the pressing button, avoiding cleaning dead corners and improving hygiene.

[0031] like Figure 1 As shown, the panel bracket 1 has a second top surface area 11 located on one side of the mounting cavity 10. The first top surface area 21 and the second top surface area 11 are spliced ​​together to form a complete top surface. Of course, in fact, the panel bracket 1 may not have a second top surface area 11, that is, the complete top surface is formed by splicing two first top surface areas 21, which greatly improves the convenience of operation and the coordination of the shape. Preferably, corresponding markings can be set on the two first top surface areas 21, namely a large drainage volume marking and a small drainage volume marking. This spliced ​​top surface structure provides two assembly methods: one is that the panel bracket 1 has a second top surface area 11, which is suitable for the combination of a single-sided pressing part + fixed panel; the other is that the complete top surface is formed by splicing two pressing parts 2, which is suitable for symmetrical double pressing design. The latter is more conducive to realizing dual flushing function and has stronger visual symmetry. It can flexibly adapt to different water tank models and user needs, improving product versatility.

[0032] As a preferred embodiment, the bottom of the mounting cavity 10 has a pressing area 101 and flat areas 102 located on both sides of the pressing area 101. The bottom of the pressing area 101 has a V-shaped structure, with the middle being lower and the sides higher. The pivot P, which is rotatably connected to the panel bracket 1, is located at one end of the pressing area 101 near the flat area 102, so that the pivot P is positioned as close as possible to the two side edges, allowing as much of the first top surface area 21 as possible to be pressed. The V-shaped bottom structure and the offset arrangement of the pivot P together optimize the lever arm distribution. When the pivot P is set close to the edge, the effective pressing area of ​​the pressing element 2 expands towards the center, generating sufficient rotational torque even when force is applied at a position far from the pivot. The V-shaped structure also provides space for the swing of the pressing element 2, avoiding interference with the cavity. Extending the effective lever arm further reduces the pressing force; the V-shaped structure also has a drainage guiding function to prevent water accumulation; and it optimizes the use of internal space, improving structural compactness.

[0033] To achieve the oscillation of the pressing element 2, such as Figures 3 to 5 As shown, the panel bracket 1 has a slot hole 12 and a shaft post 13 located in the slot hole 12. The pressing member 2 has a plug plate 22 that inserts into the slot hole 12. The plug plate 22 has a guide channel 23 for the shaft post 13 to engage when it is inserted into the slot hole 12, and a shaft hole 24 that communicates with the guide channel 23 and can be fitted onto the shaft post 13. This enables convenient installation. To prevent the pressing member 2 from coming off, preferably, an anti-disengagement structure can be provided between the pressing member 2 and the panel bracket 1 to prevent the pressing member 2 from swinging upward and thus preventing it from coming off. Figures 3 to 5 As shown, the anti-detachment structure includes a limiting support plate 25 disposed on the pressing member 2 and inserted into the slot hole 12. The panel bracket 1 has an anti-detachment boss 14 on one side of the slot hole 12. The limiting support plate 25 has a latching part 26 that can abut against the anti-detachment boss 14 when the pressing member 2 swings upward. This connection structure adopts a dual positioning method of "guide channel + shaft hole": the guide channel 23 is used to guide the shaft 13 to smoothly enter the shaft hole 24 during the assembly process, realizing rapid alignment; the shaft hole 24 is used to form a stable rotating pair. The anti-detachment structure limits the upward displacement of the pressing member 2 in abnormal states by the contact limiting of the latching part 26 and the anti-detachment boss 14, preventing detachment due to vibration or misoperation. The assembly process does not require additional tools, realizing "slide-in and positioning", improving production efficiency; the anti-detachment structure does not require screws or retaining rings, simplifying the structure and reducing costs; the dual limiting ensures the structural stability during long-term use.

[0034] As a preferred embodiment, in order to ensure that the pressing member 2 can swing smoothly and stably within a preset angle, a limiting structure can be provided between the panel support 1 and the pressing member 2 to restrict the swing angle of the pressing member 2. For example... Figures 3 to 5as shown, the described limiting structure comprises a limiting groove 27 disposed on the pressing member 2, and a limiting boss 15 disposed on the panel bracket 1 and inserted into the limiting groove 27. When the pressing member 2 swings upward until the limiting boss 15 abuts against the groove wall of the limiting groove 27, the first top surface regions 21 of the two pressing members 2 are substantially flush and in a horizontal state; the limiting groove 27 is provided with an arc-shaped side groove surface 271 for abutting against the limiting boss 15, the groove bottom of the limiting groove 27 is provided with an arc-shaped convex rib 272 for abutting against the limiting boss 15, and the centers of the circles of the arc-shaped side groove surface 271 and the arc-shaped convex rib 272 both coincide with the rotating shaft of the pressing member 2. The limiting structure adopts an arc-shaped matching design, which ensures that the limiting boss 15 moves along a circular trajectory inside the limiting groove 27, the movement trajectory is consistent with the rotation center of the pressing member 2, and lateral friction or jamming is avoided. The arc-shaped side groove surface 271 limits the maximum upward swing angle, and the arc-shaped convex rib 272 limits the maximum pressing-down stroke, so as to precisely control the swing range. Precise angle control is realized to ensure that the pressing member 2 remains horizontal after reset, improving the aesthetic appearance; the arc-shaped fit reduces wear and prolongs the service life; the bidirectional limiting protects the internal trigger assembly and prevents the water valve button from being damaged by overpressure.

[0035] As a preferred embodiment, as shown in Figure 6 , the described trigger assembly 3 is provided with a sliding member 31 and a guide post 32 arranged parallel to each other, and the panel bracket 1 is provided with a sliding hole 16 for the sliding member 31 to slidably pass through, and a guide hole 17 for the guide post 32 to slidably pass through. The sliding member 31 directly transmits the pressing force to the water valve button, and the guide post 32 cooperates with the guide hole 17 to form a guide pair, ensuring that the sliding member 31 moves only in the vertical direction and avoiding eccentric load or inclination. This dual-guide post structure improves motion stability and prevents the trigger assembly 3 from twisting or jamming during operation. It enhances the reliability and consistency of the triggering action, shares lateral forces to protect the water valve button from shear stress; the integrated design of the guide post and the sliding member is optional, which facilitates injection molding and reduces manufacturing costs.

[0036] The above are only the embodiments of the present utility model, and common general knowledge such as specific structures and characteristics well-known in the solutions are not described in excessive detail herein. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present utility model, which shall also be regarded as the protection scope of the present utility model, and these will not affect the implementation effects of the present utility model and the practicability of the patent. The protection scope claimed by the present application shall be subject to the content of the claims, and the descriptions such as the specific embodiments in the specification can be used to interpret the content of the claims.
