Description

Technical Field

[0001] This invention belongs to the field of smart toilet button technology, and specifically relates to an integrated toilet button structure. Background Technology

[0002] As people's demands for quality of life increase, smart toilets are gradually becoming a necessity. Smart toilets not only have traditional manual flush buttons but also a flushing actuator for automatic flushing, making them more convenient to use. However, existing smart toilets use a separate design where the manual flush button is located on the tank lid and the flushing actuator is located inside the tank. This results in the actuator being either close to or below the water level line, making it prone to short circuits due to water ingress. Furthermore, the overall structure is complex, making maintenance difficult and production costs high. Summary of the Invention

[0003] To address the aforementioned problems, this invention discloses an integrated toilet button structure to overcome or at least partially solve these problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This invention provides an integrated toilet button structure, including a button assembly and a drive assembly;

[0006] The button assembly includes a button lever and a pressing lever. The pressing lever is located below the button lever and is used to press down the toilet's flush valve button, so that when the button lever is pressed, the button lever can drive the pressing lever to move downward.

[0007] The driving assembly includes a driving block and a driving source. The driving source can drive the driving block to move in a horizontal direction. The driving block is provided with a driving inclined surface. The pressing rod is provided with a pressing rod inclined surface that cooperates with the driving inclined surface. The pressing rod inclined surface is located below the driving inclined surface. When the driving source drives the driving block to move in a horizontal direction, the driving inclined surface provides downward pressure to the pressing rod inclined surface, driving the pressing rod to move downward.

[0008] Furthermore, the driving source is a motor, a gear is sleeved on the motor shaft of the motor, and the driving block is provided with teeth that mesh with the gear.

[0009] Furthermore, the button lever includes a first button lever and a second button lever arranged in parallel, and the pressing lever includes a first pressing lever and a second pressing lever arranged in parallel. The first pressing lever is located below the first button lever and is used to press down the half-press button of the drain valve button. The second pressing lever is located below the second button lever and is used to press down the full-press button of the drain valve button.

[0010] The driving block is located between the first pressing rod and the second pressing rod, and one end of the driving block is provided with a first driving inclined surface, and the other end of the driving block is provided with a second driving inclined surface. The first pressing rod is provided with a first pressing rod inclined surface that cooperates with the first driving inclined surface, and the second pressing rod is provided with a second pressing rod inclined surface that cooperates with the second driving inclined surface.

[0011] Furthermore, the driving component also includes a circuit board and a Hall switch;

[0012] The drive block is equipped with a magnet, and when the drive block moves to the middle position between the first pressing rod and the second pressing rod, the magnet and the Hall switch are in corresponding positions, and the Hall switch and the motor are both connected to the circuit board for signal transmission.

[0013] Furthermore, it also includes a housing assembly, which includes a fixedly connected upper button housing and a lower button housing. The driving block, the gear, the first pressing rod, and the second pressing rod are all located inside the lower button housing. The upper button housing has a first through hole and a second through hole. The lower end of the first button rod passes through the first through hole and corresponds to the upper end of the first pressing rod. The lower end of the second button rod passes through the second through hole and corresponds to the upper end of the second pressing rod.

[0014] A first limiting ring is fitted on the first button rod below the first through hole, and the outer diameter of the first limiting ring is larger than the inner diameter of the first through hole; a second limiting ring is fitted on the second button rod below the second through hole, and the outer diameter of the second limiting ring is larger than the inner diameter of the second through hole.

[0015] Furthermore, the lower housing of the button is provided with a first guide hole and a second guide hole. The first pressing rod passes through the lower housing of the button via the first guide hole, and the second pressing rod passes through the lower housing of the button via the second guide hole, so that the first pressing rod and the second pressing rod can only move in the vertical direction.

[0016] Furthermore, the lower shell of the button is provided with a limiting protrusion, which is located below the driving block to prevent the driving block from shaking up and down.

[0017] Furthermore, the lower shell of the button has raised ribs along the vertical direction on the surface that contacts the driving block.

[0018] Furthermore, the button assembly also includes a valve stem;

[0019] The upper end of the valve stem and the lower end of the lower pressure rod are fixedly connected by a threaded structure. A locking nut is fitted on the valve stem, which is used to lock and fix the valve stem and the lower pressure rod.

[0020] Furthermore, the button assembly also includes an elastic element;

[0021] The elastic element is used to provide a restoring force for the pressure rod after it has been pressed down.

[0022] The advantages and beneficial effects of this invention are:

[0023] In the integrated toilet button structure of this invention, a pressing rod is provided for pressing down the drain valve button of the toilet, and a button rod is provided above the pressing rod. When the button rod is pressed, the button rod can drive the pressing rod to press down the drain valve button, realizing manual flushing of the button structure; furthermore, by providing a driving source and a driving block with a driving slope, and a pressure rod slope surface on the pressing rod that cooperates with the driving slope surface, when the driving source drives the driving block to move in the horizontal direction, the driving slope surface can provide downward pressure to the pressure rod slope surface, driving the pressing rod to press down the drain valve button, realizing automatic flushing of the button structure. Automatic flushing; This integrated toilet button structure achieves a combined design of manual and automatic flushing, making the structure simpler and more compact, easy to disassemble and maintain, and with low production costs. Manual and automatic flushing do not interfere with each other. Furthermore, because the integrated toilet button structure can be fixed to the toilet tank lid, the drive source is kept away from the working water level line of the tank, effectively preventing water ingress failure. At the same time, this integrated toilet button structure can be directly applied to existing toilet structures, making installation convenient and requiring no additional design to the toilet structure, further reducing toilet production costs.

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0038] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] One embodiment of the present invention discloses an integrated toilet button structure, including a button assembly and a drive assembly.

[0040] Specifically, such as Figure 1 , Figures 4 to 7 As shown, the button assembly includes a button lever 1 and a pressing lever 2. The pressing lever 2 is located below the button lever 1 and is used to press down the toilet's flush valve button 3. That is, when the integrated toilet button structure is installed inside the toilet tank, the pressing lever 2 is suspended above the toilet's flush valve button 3, or the lower end of the pressing lever 2 abuts against the toilet's flush valve button 3. Thus, when the button lever 1 is pressed, it drives the pressing lever 2 to move downwards, pressing the flush valve button 3 and opening the toilet's flush valve for manual flushing. When the button lever 1 is not pressed, the return of the flush valve button 3 drives the pressing lever 2 to move upwards, resetting it to its initial position (i.e.,...). Figure 4(The location of the lower pressure bar 2).

[0041] Of course, the button assembly may also include an elastic element 20, which provides a restoring force to the pressing lever 2 after it has been pressed down. When the button lever 1 is not pressed, the elastic element 20 will drive the pressing lever 2 to move upward and reset it to its initial position.

[0042] And, as Figure 3 , Figure 5 , Figure 6 , Figures 9 to 11 As shown, the drive assembly includes a drive block 4 and a drive source. The drive source can drive the drive block 4 to move horizontally. The drive block 4 is provided with a drive ramp 6, and the pressure rod 2 is provided with a pressure rod ramp 7 that cooperates with the drive ramp 6, and the pressure rod ramp 7 is located below the drive ramp 6. When the drive source is not working, the drive ramp 6 on the drive block 4 is away from or lightly attached to the pressure rod ramp 7, and no force is generated between the drive ramp 6 and the pressure rod ramp 7. In this way, when the button lever 1 is pressed to drive the pressure rod 2 to move downward, the drive ramp 6 and the pressure rod ramp 7 do not affect each other, that is, the drive ramp 6 does not affect the downward movement of the pressure rod 2, thereby ensuring that the electric drive assembly does not affect the realization of the manual flushing function of the button structure. When the drive source operates, driving the drive block 4 moves horizontally, causing the drive ramp 6 to approach and press against the pressure rod ramp 7. A force is generated between the drive ramp 6 and the pressure rod ramp 7. Due to the ramp, this force has a vertical component, which drives the pressure rod ramp 7 downwards, causing the lower pressure rod 2 to press down and press the drain valve button 3, opening the toilet's drain valve and enabling automatic flushing. When the drive source again drives the drive block 4 horizontally, causing the drive ramp 6 to move away from the pressure rod ramp 7, no force is generated between them. The lower pressure rod 2 returns to its initial position under the action of the drain valve button 3.

[0043] Alternatively, the drive source can be controlled via remote control buttons to achieve automatic flushing; or the drive source can be controlled via a sensor, for example, when the infrared sensor on the toilet detects a person leaving the toilet, it will control the drive source to work and automatically flush; or the drive source can be controlled via both remote control buttons and a sensor.

[0044] In summary, in the integrated toilet button structure of this embodiment, by setting a pressing rod for pressing down the toilet's drain valve button, and a button lever above the pressing rod, when the button lever is pressed, the button lever can drive the pressing rod to press down the drain valve button, realizing manual flushing of the button structure; furthermore, by setting a driving source and a driving block with a driving slope, and by setting a pressure rod slope on the pressing rod that cooperates with the driving slope, when the driving source drives the driving block to move in the horizontal direction, the driving slope can provide downward pressure to the pressure rod slope, driving the pressing rod to press down the drain valve button, realizing automatic flushing of the button structure; this integrated toilet button... The integrated button structure achieves a unified design for both manual and automatic flushing, resulting in a simpler and more compact structure that is easy to disassemble and maintain, lower production costs, and ensures that manual and automatic flushing do not interfere with each other. Furthermore, because the integrated toilet button structure can be fixed to the toilet tank lid, the drive source is kept away from the working water level line of the tank, effectively preventing water ingress failure. This integrated toilet button structure can also be directly applied to existing toilet structures; installation is simpler and requires only the replacement of the tank lid, eliminating the need for additional design modifications to the toilet structure or replacement of the drain valve, further reducing toilet production costs.

[0045] In this embodiment, as Figures 1 to 5 , Figure 7 and Figure 8 As shown, the integrated toilet button structure also includes a housing assembly, which includes a motor housing 26, an upper button housing 12, and a lower button housing 13.

[0046] The motor housing 26, the upper button housing 12, and the lower button housing 13 are fixedly connected by a snap-fit ​​or rotary fastener structure, which facilitates the assembly and disassembly of the motor housing 26, the upper button housing 12, and the lower button housing 13. Of course, in other embodiments, the motor housing, the upper button housing, and the lower button housing can also be fixedly connected by screws, or by a combination of two or more of the screws, snap-fit ​​structures, and rotary fastener structures.

[0047] Furthermore, the drive block 4, gear 8, and pressing rod 2 are all located inside the lower housing 13 of the button. The upper housing 12 of the button has a through hole, through which the lower end of the button rod 1 passes and corresponds to the upper end of the pressing rod 2. A limiting ring 14 is fitted on the button rod 1 below the through hole, and the outer diameter of the limiting ring 14 is larger than the inner diameter of the through hole. The limiting ring 14 is used to limit the travel of the button rod 1, preventing the button rod 1 from completely entering the upper housing 12 of the button.

[0048] Additionally, a flexible element (not shown in the figure) is fixed to the lower end face of the button lever. When the lower end of the button lever contacts the upper end of the pressing rod, the flexible element acts as a buffer and shock absorber, effectively preventing noise generation and thus improving the user experience of the toilet. Of course, in other embodiments, the flexible element can be fixed only to the upper end face of the pressing rod; or flexible elements can be fixed to both the lower end face of the button lever and the upper end face of the pressing rod. The flexible element can be a rubber sheet.

[0049] Furthermore, such as Figures 1 to 6 As shown, the button assembly also includes a valve stem 18 and a return spring 21.

[0050] The upper end of the valve stem 18 and the lower end of the pressure rod 2 are fixedly connected by a threaded structure, which allows the pressure rod 2 to press the drain valve button 3 through the valve stem 18. This not only expands the range that the pressure rod 2 can press, but also allows the drain valve button 3 to be pressed by the valve stem 18 even if it is located at the bottom of the toilet tank. Furthermore, the distance by which the valve stem 18 is screwed into the pressure rod 2 can be controlled so that the lower end of the valve stem 18 can just abut against the drain valve button 3, thus achieving the distance adjustment between the valve stem 18 and the drain valve button 3. Furthermore, a locking nut 19 is fitted onto the valve stem 18, which is used to lock and fix the valve stem 18 and the lower pressure rod 2. Specifically, the thread between the locking nut 19 and the valve stem 18 is a first thread, and the thread between the valve stem 18 and the lower pressure rod 2 is a second thread, with the first thread being a reverse thread of the second thread. In this way, when the locking nut 19 is fitted onto the valve stem 18 and abuts against the lower end of the lower pressure rod 2, the valve stem 18 and the lower pressure rod 2 can be relatively fixed and cannot rotate relative to each other, thereby achieving the locking and fixing of the two.

[0051] A return spring 21 is fitted onto the button lever 1, with its upper end connected to the upper end of the button lever 1 and its lower end connected to the button's upper housing 12. The return spring 21 has a preload; when the button lever 1 is pressed, the return spring 21 provides an upward return force to the button lever 1, causing it to return to its initial position (i.e., ...). Figure 4 (The position of the button lever 1); at the same time, the return spring 21 also provides an upward support force for the button lever 1, so that the button lever 1 will not move when the integrated toilet button structure realizes the automatic flushing function.

[0052] In this embodiment, as Figures 3 to 7 , Figures 9 to 11 As shown, the driving source is a motor 5, which is installed inside the motor housing 26. A gear 8 is sleeved on the motor shaft of the motor 5, and a tooth 9 that meshes with the gear 8 is provided on the driving block 4. The tooth 9 can be located at the upper end of the driving block 4. When the motor 5 rotates, the driving block 4 is driven to move in the horizontal direction through the meshing of the gear 8 and the tooth 9.

[0053] Of course, the driving source can also be other devices that can provide power. For example, the driving source can be a pneumatic cylinder or an electric cylinder, and the piston rod of the pneumatic cylinder or the electric cylinder is fixedly connected to the driving block.

[0054] Furthermore, the button lever 1 includes a first button lever 1-1 and a second button lever 1-2 arranged in parallel, and the pressing lever 2 includes a first pressing lever 2-1 and a second pressing lever 2-2 arranged in parallel. The first pressing lever 2-1 is located below the first button lever 1-1 and is used to press down the half-press button of the drain valve button 3. The second pressing lever 2-2 is located below the second button lever 1-2 and is used to press down the full-press button of the drain valve button 3. The driving block 4 is located between the first pressing lever 2-1 and the second pressing lever 2-2, and one end of the driving block 4 is provided with a first driving inclined surface 6-1, and the other end of the driving block 4 is provided with a second driving inclined surface 6-2. The pressure rod 2-1 has a first pressure rod inclined surface 7-1 that cooperates with the first driving inclined surface 6-1, and the second pressure rod 2-2 has a second pressure rod inclined surface 7-2 that cooperates with the second driving inclined surface 6-2. When the driving source drives the driving block 4 to move towards the first pressure rod 2-1, the first driving inclined surface 6-1 and the first pressure rod inclined surface 7-1 cause the first pressure rod 2-1 to move downward, pressing the half-stroke button of the drain valve button 3. When the driving source drives the driving block 4 to move towards the second pressure rod 2-2, the second pressure rod 2-2 causes the second pressure rod 2-2 to move downward, pressing the full-stroke button of the drain valve button 3. Of course, the first pressure rod can also be used to press the full-stroke button of the drain valve button, and the second pressure rod can also be used to press the half-stroke button of the drain valve button.

[0055] Thus, when the first button lever 1-1 is pressed, the first pressing lever 2-1 is driven to press down the drain valve button 3 to activate the half-flush function, or when the drive source drives the first pressing lever 2-1 to press down the drain valve button 3 to activate the half-flush function, the toilet can perform a half-flush. When the second button lever 1-2 is pressed, the second pressing lever 2-2 is driven to press down the drain valve button 3 to activate the full-flush function, or when the drive source drives the second pressing lever 2-2 to press down the drain valve button 3 to activate the full-flush function, the toilet can perform a full-flush. Therefore, this integrated toilet button structure can achieve two different flush amounts, which can be perfectly matched with existing drain valves that have both large and small flush functions.

[0056] In addition, the through holes on the button upper shell 12 are divided into a first through hole and a second through hole. The lower end of the first button rod 1-1 passes through the first through hole and corresponds to the upper end of the first pressing rod 2-1. The lower end of the second button rod 1-2 passes through the second through hole and corresponds to the upper end of the second pressing rod 2-2. The limiting ring 14 includes a first limiting ring 14-1 and a second limiting ring 14-2. The first limiting ring 14-1 is sleeved on the first button rod 1-1 below the first through hole, and the outer diameter of the first limiting ring 14-1 is larger than the inner diameter of the first through hole. The second limiting ring 14-2 is sleeved on the second button rod 1-2 below the second through hole, and the outer diameter of the second limiting ring 14-2 is larger than the inner diameter of the second through hole.

[0057] In addition, the valve stem 18 includes a first valve stem 18-1 and a second valve stem 18-2, the locking nut 19 includes a first locking nut 19-1 and a second locking nut 19-2, the return spring 21 includes a first return spring 21-1 and a second return spring 21-2, and the elastic element 20 includes a first elastic element 20-1 and a second elastic element 20-2.

[0058] Specifically, the upper end of the first valve stem 18-1 and the lower end of the first pressure rod 2-1, as well as the upper end of the second valve stem 18-2 and the lower end of the second pressure rod 2-2, are fixedly connected by a threaded structure. The first locking nut 19-1 is sleeved on the first valve stem 18-1 and is used to lock and fix the first valve stem 18-1 and the first pressure rod 2-1. The second locking nut 19-2 is sleeved on the second valve stem 18-2 and is used to lock and fix the second valve stem 18-2 and the second pressure rod 2-2. The first return spring 21-1 is sleeved on the first button lever 1-1. The upper end of the first return spring 21-1 is connected to the upper end of the first button lever 1-1, and the lower end of the first return spring 21-1 is connected to the button upper shell 12. It is used to provide an upward return force for the first button lever 1-1. The second return spring 21-2 is sleeved on the second button lever 1-2. The upper end of the second return spring 21-2 is connected to the upper end of the second button lever 1-2, and the lower end of the second return spring 21-2 is connected to the button upper shell 12. It is used to provide an upward return force for the second button lever 1-2. The first elastic element 20-1 and the second elastic element 20-2 can be springs, and both the first elastic element 20-1 and the second elastic element 20-2 are provided with preload. The first elastic element 20-1 is sleeved on the first pressing rod 2-1, with its upper end connected to the first pressing rod 2-1 and its lower end connected to the lower housing 13 of the button, for providing an upward restoring force to the first pressing rod 2-1. The second elastic element 20-2 is sleeved on the second pressing rod 2-2, with its upper end connected to the second pressing rod 2-2 and its lower end connected to the lower housing 13 of the button, for providing an upward restoring force to the second pressing rod 2-2.

[0059] In this embodiment, as Figure 3 and Figure 6 As shown, the drive assembly also includes a circuit board and a Hall switch 10.

[0060] Specifically, the drive block 4 is equipped with a magnet 11, and the Hall switch 10 is fixed to the lower shell 13 of the button or the motor 5. When the drive block 4 moves to the middle position between the first pressing rod 2-1 and the second pressing rod 2-2, that is, when both the first pressing rod 2-1 and the second pressing rod 2-2 are in their initial positions, the magnet 11 and the Hall switch 10 are in corresponding positions, and both the Hall switch 10 and the motor 5 are connected to the circuit board for signal transmission. When the drive block 4 moves to the position where the magnet 11 and the Hall switch 10 coincide, the Hall switch 10 generates an electrical signal and transmits it to the circuit board. The circuit board then controls the motor 5 to stop rotating, achieving precise control of the rotation of the motor 5.

[0061] Furthermore, compared to simply controlling the motor using time-based logic, Hall effect switches are more reliable. Because controlling the motor using time-based logic suffers from the problem of accumulated time variations—meaning there's a slight delay or extension during each motor run—this accumulated delay can cause the motor's stopping position to gradually deviate from the set position. This could lead to a situation where, when the motor stops, the drive block isn't positioned between the first and second pressure levers, causing either lever to press down on the drain valve button, keeping the drain valve in a continuous draining state. In contrast, the Hall effect switch uses a switch-like logic where the motor stops upon receiving a signal. Moreover, the Hall effect switch sends a signal precisely at the moment the magnet senses the signal, ensuring the motor stops at a consistently consistent position and preventing the accumulation of time variations.

[0062] In addition, such as Figure 7 and Figure 8 As shown, the lower housing 13 of the button is provided with a guide hole 15, which includes a first guide hole 15-1 and a second guide hole 15-2. The first pressing rod 2-1 passes through the lower housing 13 of the button via the first guide hole 15-1, and the second pressing rod 2-2 passes through the lower housing 13 of the button via the second guide hole 15-2, so that the first pressing rod 2-1 and the second pressing rod 2-2 can only move in the vertical direction, thereby realizing the movement guidance of the first pressing rod 2-1 and the second pressing rod 2-2.

[0063] In addition, such as Figures 7 to 9 As shown, the lower housing 13 of the button has a raised rib 17 along the vertical direction on the surface that contacts the driving block 4. The raised rib 17 can reduce the contact area between the lower housing 13 of the button and the driving block 4, thereby reducing the friction between them. In addition, the lower housing 13 of the button has a limiting protrusion 16, which is located below the driving block 4. Through the cooperation of the gear 8 and the limiting protrusion 16, the driving block 4 can be limited in the vertical direction to prevent the driving block 4 from shaking up and down.

[0064] In this embodiment, as Figures 3 to 9 As shown, a protrusion 24 extends axially on the gear 8, and a positioning groove 27 is provided on the lower housing 13 of the button to accommodate the protrusion 24. That is, when the gear 8 is assembled in the lower housing 13 of the button, the protrusion 24 on the gear 8 is located in the positioning groove 27, thereby achieving positioning support for the gear 8.

[0065] In addition, such as Figures 1 to 5 As shown, the housing assembly also includes a retaining nut 22.

[0066] Specifically, the upper end of the button housing 12 is provided with a fixing flange 23 along the circumferential direction, and the outer circumference of the button housing 12 is provided with threads that mate with the fixing nut 22. When the integrated toilet button structure is fixed on the water tank cover 25, the button housing 12 passes through the water tank cover 25, and the fixing flange 23 is located on the upper side of the water tank cover 25, while the fixing nut 22 is located on the lower side of the water tank cover 25. Through the clamping engagement of the fixing nut 22 and the fixing flange 23, the button housing 12 can be firmly fixed on the water tank cover 25, and it is easier to assemble and disassemble.

[0067] The above description is merely a specific embodiment of the present invention. Under the teachings of the present invention, those skilled in the art can make other improvements or modifications based on the above embodiments. Those skilled in the art should understand that the above specific description is only to better explain the purpose of the present invention, and the scope of protection of the present invention should be determined by the scope of the claims.
