Description

Technical Field

[0001] This utility model relates to the field of toilet technology, and in particular to a seat-sensing automatic flushing toilet. Background Technology

[0002] In the field of bathroom fixtures, toilets, as a common facility in daily life, have always been a focus of attention due to the convenience and hygiene of their flushing mechanisms. Traditional toilets mostly use manual buttons or levers for flushing, requiring manual operation by the user, which is not only inconvenient but also prone to cross-infection of bacteria, posing certain hygiene risks. With the development of technology, automatic flushing toilets have gradually emerged. However, most existing automatic flushing toilets require external power supply, necessitating complex wiring during installation, placing higher demands on bathroom decoration and layout, and posing a risk of electric leakage, thus requiring improvement in safety.

[0003] Furthermore, some automatic flushing toilets currently use infrared sensing technology to achieve their automatic flushing function. However, the infrared sensor needs to continuously emit and receive infrared signals to monitor whether anyone is around the toilet in real time, which puts the entire system in a state of continuous operation for a long time. Even when the toilet is not in use, the infrared sensor continues to run, resulting in continuous power consumption and a problem of excessive energy consumption.

[0004] Therefore, there is an urgent need to develop a safer, more convenient, and energy-efficient automatic flushing toilet. Utility Model Content

[0040] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0041] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0042] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0043] like Figures 1 to 5 As shown, this embodiment provides a seat-sensing automatic flushing toilet, including a flushing control device 1, a seat ring 2, a mechanism box 3, and a flushing actuator (not shown in the figure). The seat ring 2 is movably installed in the mechanism box 3. Specifically, the flushing actuator used in this embodiment is prior art. In some embodiments, the automatic flushing mechanism of the toilet with application number 202411500742.0 can be used.

[0044] The flushing control device 1 includes a pressure detection mechanism 11, a wireless control module 12, and a power supply mechanism 13. The pressure detection mechanism 11, the wireless control module 12, and the power supply mechanism 13 are all installed inside the core box 3.

[0045] The power supply mechanism 13 is electrically connected to the wireless control module 12 and is used to provide working power to the wireless control module 12.

[0046] The pressure detection mechanism 11 is electrically connected to the wireless control module 12 and is used to detect the pressure change of the seat ring 2 and transmit the detected pressure signal of the seat ring 2 to the wireless control module 12.

[0047] The wireless control module 12 is communicatively connected to the flushing actuator. After receiving the pressure signal from the pressure detection mechanism 11, the wireless control module 12 controls the flushing actuator to start flushing.

[0048] This automatic flushing toilet with seat sensor effectively solves the problems existing in the background technology through innovative design. First, the flushing control device of this utility model is equipped with a power supply mechanism 13, which is connected to the wireless control module 12. This allows the entire system to operate without an external power source, avoiding the complex wiring process required when installing the toilet, reducing installation difficulty and limitations on bathroom layout, and eliminating the safety hazard of leakage caused by an external power source.

[0049] Secondly, the pressure detection mechanism 11 works in conjunction with the wireless control module 12, changing the traditional mode where infrared sensors need to operate continuously. This new type of automatic flushing toilet with seat-sensing mechanism only activates the entire circuit when the user sits on the seat ring 2, triggering the pressure detection mechanism 11 to detect a change in the pressure of the seat ring 2. The wireless control module 12 only controls the flushing actuator to start flushing when the pressure signal changes after the user leaves the seat ring 2. This pressure-change-triggered working mechanism ensures the toilet only consumes power during actual use, significantly reducing ineffective working time compared to continuously operating infrared sensors, thus significantly lowering energy consumption and achieving greater energy savings. Simultaneously, the pressure-change-based detection method is more accurate, effectively avoiding false flushing or non-flushing due to environmental interference caused by infrared sensors, improving operational stability.

[0050] Furthermore, through the coordinated operation of the flushing control device 1, seat ring 2, core box 3, and flushing execution device, the automatic flushing toilet with seat sensor of this utility model realizes the automatic flushing function, eliminating the need for manual operation, reducing the chance of cross-infection of bacteria, improving the hygiene and convenience of use, and bringing users a more comfortable, safe, and energy-saving bathroom experience.

[0051] In one embodiment, the wireless control module 12 includes a circuit board 121 and a wireless signal transmitter 122; the signal input terminal of the wireless signal transmitter 122 is electrically connected to the circuit board 121, and the signal output terminal of the wireless signal transmitter 122 is communicatively connected to the water circuit switch mechanism of the flushing actuator, for sending a flushing signal or a water shut-off signal to the water circuit switch mechanism of the flushing actuator, thereby opening or closing the water circuit switch mechanism, and thus controlling the flushing actuator to start or stop flushing;

[0052] The power supply mechanism 13 is electrically connected to the circuit board 121, and the pressure detection mechanism 11 is electrically connected to the circuit board 121.

[0053] The wireless control module 12, through the integrated design of the circuit board 121 and the wireless signal transmitter 122, achieves precise processing and wireless transmission of pressure signals. Furthermore, using the wireless signal transmitter 122 for signal transmission avoids the cumbersome wiring of traditional wired connections. Simultaneously, wireless communication reduces wear on mechanical contacts, improving system stability and lifespan. Moreover, the communication function can be controlled to activate only when pressure is triggered, further reducing energy consumption.

[0054] Preferably, the water circuit switch mechanism of the flushing actuator is a solenoid valve. By utilizing the characteristics of fast response speed and high control precision of the solenoid valve, the real-time execution and precise start and stop of the flushing command can be ensured.

[0055] In one embodiment, the pressure detection mechanism 11 includes an elastic force transmission component 111 and a pressure sensor 112. The pressure sensor 12 is electrically connected to the circuit board 121. The elastic force transmission component 111 is elastically mounted on the top surface of the circuit board 121 in a vertical direction, forming an elastic abutment. The elastic force transmission component 111 covers the pressure sensor 112, and its top extends to the outside of the mechanism box 3. The cooperation between the elastic force transmission component 111 and the pressure sensor 112 forms a sensitive pressure sensing structure. This design directly transmits pressure to the pressure sensor 112 through the deformation of the elastic force transmission component 111, avoiding the mechanical loss of rigid contact. Simultaneously, the elastic reset characteristic ensures the repeatability and reliability of pressure detection, effectively improving the stability and anti-interference capability of the sensing system.

[0056] Preferably, in the initial state (i.e., when the elastic force transmission component 111 is not subjected to external force or the pressure is lower than a preset pressure value), the top of the elastic force transmission component 111 protrudes from the top surface of the mechanism box 3, and there is a gap between the elastic force transmission component 111 and the pressure sensor 12. That is, in the initial state, the elastic force transmission component 111 maintains a non-contact state with the pressure sensor 12 through its own elastic force. When the pressure on the elastic force transmission component 111 is greater than the preset pressure value, the elastic force transmission component 111 compresses downward and presses the pressure sensor 112, so that the pressure sensor 112 generates a pressure signal and transmits it to the circuit board 121.

[0057] In one embodiment, the bottom of the seat ring 2 is provided with a pressing mechanism 21, and the bottom of the pressing mechanism 21 protrudes from the bottom surface of the seat ring 2. The position of the pressing mechanism 21 corresponds to the position of the pressure detection mechanism 11. When the seat ring 2 is subjected to force, the pressing mechanism 21 presses the pressure detection mechanism 11. The pressure detection mechanism 11 detects the pressure change of the seat ring 2 and transmits the detected pressure signal of the seat ring 2 to the wireless control module 12.

[0058] It is worth noting that the pressing mechanism 21 at the bottom of the seat ring 2 corresponds to the pressure detection mechanism 11, forming a direct pressure transmission path. When the user sits down, the pressing mechanism 21 directly presses down on the elastic force transmission component 111, ensuring that the pressure signal is quickly and accurately transmitted to the pressure sensor 112, avoiding signal attenuation or delay caused by indirect transmission. This structural design makes pressure detection more targeted, responding only to the actual force state of the seat ring 2, effectively eliminating external interference such as environmental vibration, and improving the accuracy and reliability of the sensing.

[0059] In one embodiment, the elastic force transmission component 111 includes an elastic cup 1111 and a force guide column 1112, wherein the force guide column 1112 is installed on the elastic cup 1111 in a vertical direction;

[0060] The elastic cup 1111 covers one end of the circuit board 121 near the seat ring 2, and the pressure sensor 112 is located in the movable cavity 1113 formed between the elastic cup 1111 and the circuit board 121;

[0061] The top of the mechanism box 3 is provided with a movable hole 31 for the guide column 1112 to move;

[0062] The position of the pressing mechanism 21 corresponds to the position of the guide column 1112. The top of the guide column 1112 extends through the movable hole 31 to the outside of the mechanism box 3. The bottom of the guide column 1112 is located inside the movable cavity 1113, and the guide column 1112 is located above the pressure sensor 112.

[0063] The elastic force transmission component 111 forms a precise pressure transmission and displacement control mechanism through the vertical linkage structure of the elastic cover cup 1111 and the guide column 1112. First, the guide column 1112 is installed vertically on the elastic cover cup 1111, with its top extending to the outside through the movable hole 31 of the movement box 3, and its bottom suspended in the movable cavity 1113 and directly above the pressure sensor 112. This ensures that the vertical pressure of the seat ring 2 is directly and without offset transmitted to the pressure sensor 112 through the guide column 1112, avoiding signal errors caused by tilted force and improving the accuracy of pressure detection.

[0064] Specifically, when someone sits on the seat ring 2, the guide column 1112 is pressed by the seat ring 2, and the elastic cover 1111 deforms and compresses downward, causing the guide column 1112 to squeeze the pressure sensor 112 and trigger a signal. After the pressure is released, the elastic cover 1111 pushes the guide column 1112 upward to reset by its own elastic force, so that the top of the guide column 1112 protrudes out of the top surface of the mechanism box 3 again, ensuring that the detection mechanism can return to the initial state after each use, achieving repeatable and sensitive pressure response, and avoiding fatigue or jamming of the mechanical structure due to long-term pressure.

[0065] Furthermore, the design of the top of the guide column 1112 being exposed outside the mechanism box 3 shortens the action path between the pressing mechanism 21 and the guide column 1112, significantly reducing pressure transmission delay. The moment the user sits down, the pressing mechanism 21 presses the guide column 1112, which then quickly triggers the pressure sensor 112 through vertical displacement. Compared to traditional indirect transmission structures, this results in a faster response speed, ensuring timely activation of the automatic flushing function and optimizing the user experience.

[0066] Preferably, the top of the movement box 3 is also provided with an elastic sealing panel (not shown in the figure). The elastic sealing panel is placed above the movable hole 31, and the periphery of the elastic sealing panel is connected to the outer surface of the movement box 3. By setting the elastic sealing panel, the movable hole 31 can be covered to prevent moisture and dust from entering the interior of the movement box 3 through the movable hole 31.

[0067] Preferably, the elastic sealing panel is adhered to the outer surface of the mechanism box 3 on all four sides to achieve a tight contact. The elastic sealing panel is made of a flexible material, allowing it to deform under stress. In some embodiments, the elastic sealing panel may be made of silicone, rubber, or thermoplastic polyurethane, etc.

[0068] In one embodiment, the elastic force transmission component 111 is made of rubber or thermoplastic polyurethane. Utilizing the high elasticity and fatigue resistance of rubber and thermoplastic polyurethane, the elastic force transmission component 111 ensures that it returns to its initial state after the human body leaves the seat ring 2, avoiding elastic decay or permanent deformation due to long-term use. This not only improves the durability of the pressure detection mechanism 11, but also ensures the continuous sensitive response of the pressure sensor 112 to pressure changes in the seat ring 2 through stable elastic reset performance, maintaining the long-term reliability of the sensing system.

[0069] In one implementation, such as Figure 1 and Figure 5 As shown, the internal part of the core box 3 is provided with a mounting mechanism 32 for installing the flushing control device 1. The circuit board 121 and the mounting mechanism 32 are fixedly connected, and a mounting cavity 33 is formed between the circuit board 121 and the mounting mechanism 32.

[0070] The side wall of the mechanism box 3 is provided with a mounting hole 34 for the power supply mechanism 13 to move. The power supply mechanism 13 passes through the mounting hole 34 and is detached and installed in the mounting cavity 33.

[0071] In one implementation, such as Figure 4 and Figure 5 As shown, the installation mechanism 32 includes an installation mechanism body 321, a self-locking buckle 322, and an elastic fitting component 323;

[0072] The main body 321 of the mounting mechanism is provided with a dividing plate 3211 inside, which divides the mounting cavity 33 into a first mounting cavity 331 and a second mounting cavity 332; the power supply mechanism 13 is detached and installed in the first mounting cavity 331, and the elastic force transmission component 111 is located in the second mounting cavity 332.

[0073] The self-locking buckle 322 and the elastic fitting component 323 are respectively installed on both sides of the first mounting cavity 331;

[0074] The power supply mechanism 13 includes a battery 131 and a battery mounting base 132. The battery mounting base 132 has a battery mounting slot 1324 for mounting the battery 131, and the battery 131 is detachably installed and removed from the battery mounting slot 1324. One side of the battery mounting base 132 is detachably connected to the self-locking buckle 322, and the other side of the battery mounting base 132 abuts against the elastic engagement component 323. The power supply mechanism 13 achieves a quick installation and removal function of "press to lock, then press to pop out" through the engagement of the self-locking buckle 322 and the abutment of the elastic engagement component 323, enabling quick installation and removal of the power supply mechanism 13 without tools.

[0075] Specifically, during installation, pressing the battery mounting base 132 will automatically engage one side of the battery mounting base 132 with the self-locking buckle 322; during disassembly, pressing again will release the battery mounting base 132 with the self-locking buckle 322 and push the battery mounting base 132 out through the cooperation of the self-locking buckle 322 and the elastic engagement component 323. The operation can be completed without tools, which significantly improves the convenience and efficiency of battery replacement.

[0076] It is worth noting that the circuit board 121 is provided with a positive terminal connector (not shown in the figure) and a negative terminal connector (not shown in the figure), which are used to connect the positive and negative terminals of the battery 131, respectively. Specifically, the positive terminal connector and the negative terminal connector are respectively installed at designated positions on the circuit board, so that after the power supply mechanism 13 is installed in the first mounting cavity 331, the positive and negative terminals of the battery 131 can contact the positive terminal connector and the negative terminal connector, respectively, to achieve electrical connection.

[0077] Preferably, the mounting mechanism 32 further includes a limiting member 324 for limiting the mounting position of the elastic lid 1111. The elastic lid 1111 has limiting grooves (not shown in the figure) around its perimeter that cooperate with the limiting member 324. The limiting member 324 can limit the horizontal position of the elastic lid 1111, preventing horizontal displacement of the elastic lid 1111. The cooperation between the limiting member 324 and the circuit board 121 can limit the vertical position of the elastic lid 1111, preventing vertical movement of the elastic lid 1111.

[0078] In one embodiment, the battery mounting base 132 includes a mounting base body 1321, a first connector 1322 and a second connector 1323, the first connector 1322 and the second connector 1323 are respectively connected to both sides of the mounting base body 1321, and the battery mounting groove 1324 is formed between the first connector 1322 and the second connector 1323.

[0079] The first connector 1322 abuts against the elastic fitting component 323, and the second connector 1323 is detached from the self-locking buckle 322.

[0080] The battery mounting slot 1324 formed by the first connector 1322 and the second connector 1323 securely holds the battery 131, preventing poor contact caused by toilet vibration. Simultaneously, the first connector 1322 abuts against the elastic engagement component 323, and the second connector 1323 engages with the self-locking buckle 322, forming a bidirectional fixing structure. The elastic engagement component 323 provides continuous clamping force to ensure a stable electrical connection to the battery 131, while the self-locking buckle 322 is locked in position by the second connector 1323 to prevent accidental dislodgement. This structural design ensures reliable power supply while enabling quick installation and removal of the battery 131 through modular components. Users can easily perform maintenance with a simple press, significantly lowering the barrier to entry.

[0081] In one embodiment, the elastic fitting component 323 includes a fixing member 3231 and an elastic member 3232. The fixing member 3231 is fixedly installed on the mounting mechanism body 321. One end of the elastic member 3232 is fixedly connected to the fixing member 3231, and the other end of the elastic member 3232 abuts against the first connecting member 1322.

[0082] The second connector 1323 has a snap-fit ​​part 13231 at one end away from the mounting body 1321. The self-locking buckle 322 is used to engage or release the snap-fit ​​part 13231, thereby realizing the detachable installation of the power supply mechanism 13.

[0083] In specific operation, when installing, press the mounting base body 1321, and the self-locking buckle 322 automatically locks the locking part 13231; when disassembling, press again, and the self-locking buckle 322 releases the locking part 13231, and the battery mounting base 132 is pushed out through the cooperation of the self-locking buckle 322 and the elastic element 3232, so that part of the mounting base body 1321 is exposed in the mounting hole 34. The entire power supply mechanism 13 can be directly removed without tools, which significantly improves the convenience and efficiency of battery replacement.

[0084] It should be noted that the self-locking buckle 322 used in this embodiment is existing technology. Preferably, a commercially available push-type buckle can be used, which forms a releasable locking connection with the locking part 13231 through a pressing operation, enabling the quick installation and removal of the power supply mechanism 13. Specifically, the self-locking buckle 322 includes a housing and a hook that can move along the length of the housing. When the power supply mechanism 13 needs to be installed, by pressing the battery mounting base 132, the hook moves inward toward the housing and locks the locking part 13231, so that the power supply mechanism 13 is firmly installed in the first mounting cavity 331. When the power supply mechanism 13 needs to be removed, by pressing the battery mounting base 132 again, the hook moves outward toward the housing and releases the locking part 13231, so that the power supply mechanism 13 and the self-locking buckle 322 are disengaged. At the same time, due to the elasticity of the elastic element 3232 and the outward movement of the hook, the battery mounting base 132 moves outward toward the mechanism box 3, thereby exposing part of the mounting base body 1321 through the mounting hole 34, making it convenient to remove the entire power supply mechanism 13 and thus convenient to replace the battery.

[0085] In one embodiment, the self-locking buckle 322 is a push-button buckle of model PR-3 from Bozhong.

[0086] In some implementations, the elastic element 3232 is a spring.

[0087] In one embodiment, the power supply mechanism 13 further includes a sealing ring 133.
