Figures 1 to 12 Further elaboration is made on the embodiments of the present application, wherein the structures of each part are mentioned.

[0041] The intelligent toilet is a sanitary device that combines modern technology and convenience, which is usually equipped with various intelligent functions to provide a more comfortable and convenient use experience. For example, the intelligent toilet is internally provided with multiple functional components such as a water pump, etc. for realizing various functions of the intelligent toilet such as flushing, deodorization, etc. In order to ensure the normal use of the intelligent toilet, it needs to be regularly maintained.

[0042] It can be understood that, as an intelligent toilet (for the convenience of description, which can also be referred to as "toilet" hereinafter) integrated with multiple high-tech functions, flushing is the most basic and important function of the intelligent toilet, therefore, it is crucial to efficiently and accurately detect the good or bad of the flushing component of the intelligent toilet. The flushing component is arranged in the intelligent toilet, and the intelligent toilet usually encapsulates the flushing component through ceramic in order to maintain the simplicity and neatness of the appearance. Thus, in the traditional method, the flushing component and the related circuit are detected by removing the ceramic to expose the flushing component, so as to realize the good or bad judgment of the flushing component. However, such a detection method needs to destroy the structure of the intelligent toilet as a prerequisite, and the repeated disassembly and installation make the detection efficiency of the flushing function component low.

[0043] Based on this, the embodiments of the present application propose a flushing function detection circuit and an intelligent toilet, aiming to improve the detection efficiency of the flushing function component of the intelligent toilet. The following will be described in detail, and the beneficial effects of each part will gradually appear.

[0044] Firstly, the flushing function detection circuit proposed by the embodiments of the present application is introduced, as shown in Figure 1 , Figure 2 and Figure 3 , Figure 1 is an optional structural schematic diagram of the flushing function detection circuit provided by an embodiment of the present application,

[0045] Figure 2 is another optional structural schematic diagram of the flushing function detection circuit provided by an embodiment of the present application, Figure 3 is still another optional structural schematic diagram of the flushing function detection circuit provided by an embodiment of the present application, wherein the flushing function detection circuit comprises:

[0046] a main signal lamp 110, one end of the main signal lamp 110 being grounded;

[0047] The controller 120 includes a power input end and a first control end. The power input end is used to connect with a power supply. The first control end is electrically connected with the other end of the main signal lamp 110. The first control end is used to output a first control signal to the main signal lamp 110 to control the main signal lamp 110 to turn on or off.

[0048] The controller 120 further includes a first voltage detection end and a first time detection end. The first voltage detection end and the first time detection end are both electrically connected with the first signal end of the flushing assembly. The first voltage detection end is used to receive a first electric signal from the first signal end when the flushing assembly enters a working state. The first time detection end is used to receive a second electric signal from the first signal end when the flushing assembly enters the working state. The controller 120 is a core control unit of the intelligent toilet, which is usually referred to as a control board or a main control board. The controller 120 is responsible for coordinating and managing various functions of the toilet, such as flushing and deodorizing, to ensure that each component can work normally according to the preset logic. The controller 120 can be a programmable logic controller (PLC), a distributed control system (DCS), a programmable automation controller (PAC), etc. The specific type of the controller 120 is not limited in the embodiments of the present application.

[0049] The one end of the main signal lamp 110 is electrically connected with the first control end (21-pin) of the controller 120. The other end of the main signal lamp 110 is grounded. The main signal lamp 110 can emit an explicit visual signal under a specific signal, so that the maintenance personnel can observe the current good or bad condition of the flushing assembly through the visual light signal.

[0050] Further, the power input end of the controller 120 is used to connect with a power supply. The power supply can be a commercial power supply. The commercial power supply is an alternating current power supply provided through a household power grid, which is usually 220 volts (V) or 110V. The commercial power voltage is usually different in different regions, and is adaptively adjusted according to the voltage supply scheme formulated by each region. After the intelligent toilet is connected to the commercial power supply, the built-in transformer (or voltage conversion circuit) converts the commercial power supply into low-voltage direct current (such as 12V, 24V, 5V, etc.) for use by internal electronic components such as the flushing assembly and the controller 120. The specific voltage conversion circuit is a common technical means for those skilled in the art, and will not be shown in the embodiments of the present application.

[0051] In addition, the power supply can also be a battery. In order to avoid the toilet being unable to complete the basic flushing work when the power is off, the intelligent toilet is usually equipped with a battery. When the commercial power is off, the toilet enters a working state based on the power of the backup power supply (battery).

[0052] The toilet flushing assembly includes a direct flushing mode and a pulse flushing mode. In the direct flushing mode, when the user triggers the flushing switch, the core controller disposed in the intelligent toilet sends a single electrical signal to control the opening of the flushing valve, and the water flows into the toilet at a constant pressure and speed to complete the flushing process. In the pulse flushing mode, when the user triggers the flushing switch, the core controller disposed in the intelligent toilet sends multiple pulse signals to control the opening of the water supply valve or the flushing valve. When the water supply valve is opened, the water in the toilet bowl is stored to a positioning line. When the flushing valve is opened, the toilet completes the sewage removal through siphon. The valve opening sequence of the pulse flushing mode is usually: water supply valve-flushing valve-water supply valve.

[0053] Further, the flushing assembly deployed in the toilet can be provided with the two modes described above and can be switched according to the actual needs of the user. Alternatively, flushing assemblies of different modes are deployed in different toilets, and the user can choose different toilets according to their own needs. The flushing assembly includes a first signal end, which sends an electrical signal to the connected other electronic elements when the flushing assembly enters the direct flushing mode.

[0054] The controller 120 further includes a first voltage detection end and a first time detection end, both of which are connected with the first signal end. When the flushing assembly enters the working state, the first signal end generates and sends two different electrical signals to the first signal end: one is a first electrical signal representing the voltage level, and the other is a second electrical signal representing the time information. The first voltage detection end receives the first electrical signal to monitor whether the working voltage of the flushing assembly is normal, and the first time detection end receives the second electrical signal to confirm whether the flushing assembly completes the task within the preset time range.

[0055] Alternatively, the first electrical signal and the second electrical signal can come from a single composite signal, and the first voltage detection end and the first time detection end of the controller 120 obtain the first electrical signal and the second electrical signal respectively by analyzing the composite signal.

[0056] Further, the controller 120 is deployed with a comparison determinator and a counter. The comparison determinator is used to compare the size of the first electrical signal and the preset voltage threshold, and obtain the comparison result of the two. Specifically, the controller 120 receives the first electrical signal sent by the flushing assembly through the first voltage detection end, and compares it with the preset voltage threshold. If the voltage is lower or higher than the set range, the comparison determinator outputs a first comparison signal, which is used to represent that the working voltage of the flushing assembly in the working state meets the preset requirements.

[0057] Furthermore, the counter is used to record and measure the number of time, pulses, or other events. When the flushing assembly enters the working state, the counter starts recording the duration of the flushing assembly's operation to ensure that the flushing assembly completes within a preset time range. If the flushing time meets the preset requirements, it indicates that the flushing intensity of the flushing assembly has reached the expected level, and the controller 120 outputs a first time signal, which characterizes that the working duration of the flushing assembly when it enters the working state meets the preset requirements. If the flushing time is too long or too short, it indicates that the flushing intensity of the flushing assembly has not reached the expected level, and the controller 120 can detect the abnormality through the counter and output a second time signal, which characterizes that the working duration of the flushing assembly when it enters the working state has not met the preset requirements.

[0058] In some embodiments, the flushing function detection circuit further includes a first switching transistor and a first resistor. The first terminal of the first switching transistor is electrically connected to a first signal terminal, the second terminal of the first switching transistor is used to connect to a power supply, and the third terminal of the first switching transistor is grounded. One end of the first resistor is electrically connected to the first signal terminal, and the other end of the first resistor is electrically connected to a first voltage detection terminal.

[0059] like Figure 2 As shown, the first switching transistor is Q1. In this embodiment, the first switching transistor is an NPN transistor. The base of the first switching transistor is electrically connected to the first signal terminal, the emitter of the first switching transistor is connected to the power supply, and the collector of the first switching transistor is grounded. This structure allows the first switching transistor to be turned on or off when an electrical signal from the first signal terminal of the flushing assembly is applied to the first terminal of the first switching transistor, thereby indirectly controlling the state of the main indicator light 110 through the controller 120.

[0060] In some embodiments, to optimize circuit performance and reliability, different types of switching transistors can be selected as the second switching transistor. For example, an N-channel metal-oxide-semiconductor field-effect transistor (NMOS transistor) can be used instead of a traditional bipolar transistor. NMOS transistors are characterized by low on-resistance, fast turn-on speed, and low power consumption, making them ideal for applications requiring frequent switching. In this case, the gate of the NMOS transistor corresponds to the base of a traditional bipolar transistor, the source corresponds to the emitter, and the drain is the collector. Using an NMOS transistor significantly improves the efficiency of the entire circuit and reduces the probability of overheating.

[0061] In addition, considering the problem of component aging caused by long-term operation, a temperature compensation circuit can be added between the second resistor and the second voltage detection terminal. The core idea of the temperature compensation circuit is to build a feedback loop based on thermistors or other temperature-sensitive elements. When the ambient temperature changes, the resistance of these elements will also change accordingly, thereby automatically adjusting the circuit parameters to maintain the optimal working state. Specifically, when the temperature rises, the resistance of the thermistor decreases, which will cause more current to flow into the second voltage detection terminal, and vice versa. In this way, even in extreme environments, the stability of the detection result can be ensured, prolonging the service life of the system.

[0062] As shown in Figure 3 , the first resistor is R31. The first resistor can perform voltage division processing on the electrical signal transmitted from the first signal terminal and transmit the processed signal to the first voltage detection terminal, so that the controller 120 can determine the working state of the flushing assembly according to the voltage level. This structure ensures the stability and accuracy of the signal transmission process, and prevents high voltage from directly entering the controller 120 and causing damage.

[0063] As shown in Figure 2 , the flushing function detection circuit provided by the embodiment of the application further includes a third resistor (R8) and a fourth resistor (R10). One end of the third resistor is electrically connected to the second electrode of the first switch tube, and the other end of the third resistor is used to be connected with the power supply. One end of the fourth resistor is electrically connected to the first electrode of the first switch tube, and the other end of the fourth resistor is grounded. The third resistor and the fourth resistor jointly form a voltage division network to provide a stable bias voltage for the first switch tube, ensuring that it can work normally under correct conditions.

[0064] In addition, the flushing function detection circuit can also be provided with other resistors such as resistors R9 and R11. One end of the resistor R9 is electrically connected to the first signal terminal, and the other end of the resistor R9 is electrically connected to the first electrode of the first switch tube. One end of the resistor R11 is electrically connected to the second electrode of the first switch tube, and the other end of the resistor R11 is electrically connected to the first time detection terminal of the controller 120.

[0065] Among them, the resistance value of R8 is 10 kilo-ohms (KΩ), the resistance value of R10 is 10 KΩ, the resistance value of R9 is 20 KΩ, and the resistance value of R11 is 1 KΩ. Of course, Figure 2 The resistance values of the resistors in the above embodiment are only examples, and can be adjusted according to actual conditions. GND represents the ground terminal.

[0066] As shown in Figure 3 , the flushing function detection circuit further includes a fifth resistor and a first capacitor. One end of the fifth resistor and the first capacitor is electrically connected to the first signal terminal, and the other end of the fifth resistor and the first capacitor is grounded.

[0067] Wherein, the fifth resistor is R32, and the first capacitor is C9. The fifth resistor and the first capacitor jointly play a role of filtering and smoothing signals, reduce the influence of external interference on the first voltage detection end, ensure that the signal transmitted from the first signal end to the controller 120 is more accurate and reliable, enhance the noise immunity and stability of the entire circuit, and improve the detection precision.

[0068] In some embodiments, the flushing function detection circuit provided by the embodiments of the present application further includes a buzzer and an auxiliary signal lamp 130, and the controller 120 further includes a second control end (Beep pin) and a third control end (22 pin), one end of the buzzer is electrically connected to the second control end, the other end of the buzzer is grounded, one end of the auxiliary signal lamp 130 is electrically connected to the third control end, and the other end of the auxiliary signal lamp 130 is grounded.

[0069] Wherein, the second control end is used to output a second control signal to the buzzer to control the buzzer to open or close; and the third control end is used to output a third control signal to the auxiliary signal lamp 130 to control the auxiliary signal lamp 130 to open or close. The main signal lamp 110 in the embodiments of the present application is LED1, and the auxiliary signal lamp 130 is LED2.

[0070] In addition, as shown in Figure 1 The controller of the embodiments of the present application is further connected with other electronic elements, such as a terminal CN5, which is used to burn the required program; resistors R7, capacitors C6, C7 and C8, etc. which are used to avoid the breakdown of the controller caused by the input power and play a role of filtering. The controller can be connected with other components according to the actual situation, and the embodiments of the present application do not limit this.

[0071] As shown in Figure 4 , Figure 4 is a flushing detection flowchart provided by one of the embodiments of the present application, and the specific steps are as follows:

[0072] (1) When the flushing assembly enters a working state, the first signal end of the flushing assembly transmits a first electrical signal to the first voltage detection end (V_TEST1) of the controller 120, and it is judged whether the voltage signal received by V_TEST1 meets a preset voltage threshold value. For example, the voltage threshold value can be set to 5.5V, or it can be adaptively adjusted according to the actual situation, and the embodiments of the present application do not limit this. If it meets (Y), step (2) is entered; if it does not meet (N), the main signal lamp 110 and the auxiliary signal lamp 130 are turned on at the same time, and the buzzer enters a second working state;

[0073] Wherein, the second working state of the buzzer can be long buzzing of the buzzer;

[0074] (2) If the first electric signal meets the preset voltage threshold, then it is judged whether the first time detection end (SW1) meets the preset level signal, the level signal of the embodiment of the application is a low level signal, or the level signal can also be adjusted to a high level signal according to the actual circuit condition; if it meets (Y), step (3) is entered; if it does not meet (N), the auxiliary signal lamp 130 is bright, and the buzzer enters the first working state;

[0075] The first working state of the buzzer can be short buzzing of the buzzer, and the first working state and the second working state can be adaptively adjusted according to the actual situation, as long as they are two kinds of buzzer states that are convenient to distinguish.

[0076] (3) If the second electric signal meets the preset level signal, then it is judged whether the duration of the preset level signal meets the preset time threshold, and the time threshold can be set according to the actual situation, which is not limited in the embodiment of the application; if it meets (Y), the main signal lamp 110 is bright; if it does not meet (N), the auxiliary signal lamp 130 is bright, and the buzzer enters the first working state.

[0077] It can be understood that only when the working voltage and the working duration of the flushing assembly both meet the expected state, the controller 120 will issue the only visual signal, that is, the main signal lamp 110 is bright; and other situations can also convey different fault information to the maintenance personnel through other corresponding visual signals. Since the flushing function detection circuit provided in the embodiment of the application is built-in in the intelligent toilet, the maintenance personnel does not need to disassemble the ceramic body of the toilet during maintenance, but can know the good or bad condition of the flushing assembly through the signals detected by the controller 120, thereby avoiding the low detection efficiency caused by repeated disassembly and installation of the ceramic body in the traditional detection method.

[0078] In addition, since the toilet has a pulse flushing mode, in this mode, the pulse signal emitted by the flushing assembly is very short, and the traditional detection method uses a voltmeter or a multimeter to read the voltage, which can only see the number flashing, and cannot read the value, so there is the problem of inaccurate detection. Compared with the traditional detection method, the embodiment of the application can accurately receive the current electric signal by the controller 120 when the flushing assembly enters the working state, and judge the good or bad of the flushing assembly based on the current electric signal, thereby improving the accuracy of the flushing assembly detection.

[0079] In some embodiments, to enhance the flexibility and adaptability of the alarm system, more complex configurations can be made to the buzzer and auxiliary signal light 130. For example, different alarm modes can be set according to different types of faults: for minor problems, the auxiliary signal light 130 can only change color without flashing, and the buzzer emits a soft sound; while for serious faults, the auxiliary signal light 130 can be made to flash quickly and the buzzer emits a sharp and piercing sound. In addition, a smart control system can also be introduced, which uses the microcontroller 120 to dynamically adjust the alarm level according to the actual detection results, thereby realizing a more personalized and efficient user notification mechanism.

[0080] On the other hand, considering the problem of component aging caused by long-term use, a protection circuit such as a current limiting resistor or a zener diode can be added between the buzzer and the second control terminal to prevent excessive current from damaging the buzzer. At the same time, temperature compensation elements such as thermistors can be added to the auxiliary signal light 130 circuit to adjust the brightness to adapt to changes in ambient light, ensuring clear visibility under various lighting conditions. Such design not only improves the stability and reliability of the system, but also enhances the user's perception effect.

[0081] In some embodiments, the controller 120 is provided with a Bluetooth module and is wirelessly connected to an electronic device such as a mobile phone, computer, tablet, etc. In this way, without the need to add complex wiring and without the need to disassemble the ceramic body, the judgment result of the controller 120 can be accurately known based on the electronic device, reducing the complexity of the detection of the flushing assembly of the closestool.

[0082] In some embodiments, the controller 120 further includes a second voltage detection terminal (V_TEST2) and a second time detection terminal (SW2), both of which are electrically connected to the second signal terminal of the flushing assembly; the second voltage detection terminal is used to receive a first electric signal from the second signal terminal when the flushing assembly enters the working state, and the second time detection terminal is used to receive a second electric signal from the second signal terminal when the flushing assembly enters the working state;

[0083] Further, the controller 120 further includes a third voltage detection terminal (V_TEST3) and a third time detection terminal (SW3), both of which are electrically connected to the third signal terminal of the flushing assembly; the third voltage detection terminal is used to receive a first electric signal from the third signal terminal when the flushing assembly enters the working state, and the third time detection terminal is used to receive a second electric signal from the third signal terminal when the flushing assembly enters the working state.

[0084] In some embodiments, the flushing assembly includes a second signal terminal and a third signal terminal, both of which are used to send an electrical signal to other connected electronic components when the flushing assembly enters the pulse flushing mode. Based on this, the controller 120 is provided with a second voltage detection terminal and a second time detection terminal electrically connected with the second signal terminal, and a third voltage detection terminal and a third time detection terminal electrically connected with the third signal terminal, in addition to the first voltage detection terminal and the first time detection terminal.

[0085] The second voltage detection terminal and the third voltage detection terminal have similar functions as the first voltage detection terminal, and the second time detection terminal and the third time detection terminal have similar functions as the first time detection terminal, which will not be described here.

[0086] As shown in Figure 5 , Figure 6 , Figure 5 is a second voltage detection schematic diagram of the flushing function detection circuit provided in an embodiment of the present application, Figure 6 is a second time detection schematic diagram of the flushing function detection circuit provided in an embodiment of the present application. In some embodiments, the flushing function detection circuit provided in the embodiment of the present application further includes a second switch tube (Q2) and a second resistor (R34). The first pole of the second switch tube is electrically connected with the second signal terminal, the second pole of the second switch tube is used to be connected with the power supply, and the third pole of the second switch tube is grounded. One end of the second resistor is electrically connected with the second signal terminal, and the other end of the second resistor is electrically connected with the second voltage detection terminal.

[0087] As shown in Figure 5 , the second switch tube is Q2. In the embodiment of the present application, the second switch tube is an NPN type triode, the base of the second switch tube is electrically connected with the first signal terminal, the emitter of the second switch tube is used to be connected with the power supply, and the collector of the second switch tube is grounded. This structure makes it possible to control the second switch tube to be turned on or turned off when the electrical signal from the first signal terminal of the flushing assembly acts on the first pole of the second switch tube, so as to indirectly control the state of the main signal lamp 110 through the controller 120.

[0088] As shown in Figure 6 , the second resistor is R34. The second resistor can perform voltage division processing on the electrical signal transmitted from the second signal terminal, and transmit the processed signal to the second voltage detection terminal, so that the controller 120 can determine the working state of the flushing assembly according to the voltage level. This structure ensures the stability and accuracy of the signal transmission process, and prevents damage caused by too high voltage directly entering the controller 120.

[0089] In addition, as shown in Figure 5As shown, the flushing function detection circuit provided in this application embodiment further includes a resistor R12 with a resistance of 20KΩ, a resistor R13 with a resistance of 10KΩ, a resistor R14 with a resistance of 10KΩ, and a resistor R15 with a resistance of 1KΩ; as Figure 6 As shown, the flushing function detection circuit provided in this embodiment also includes a 20KΩ resistor R35, a 1KΩ resistor R36, and a 100 nanofarad (nF) capacitor C10, which serve as voltage dividers and circuit protectors. Of course, the flushing function detection circuit can also add necessary electronic components between the resistors according to actual conditions; this embodiment does not impose any limitations on this.

[0090] Similarly, such as Figure 7 , Figure 8 As shown, Figure 7 This is a schematic diagram of an optional third voltage detection circuit for a flushing function detection circuit provided in one embodiment of this application. Figure 8 This is an optional third time detection schematic diagram of a flushing function detection circuit provided in one embodiment of this application. The flushing function detection circuit provided in this embodiment of the application also includes a third switch Q3 and a voltage divider resistor R20.

[0091] In addition, such as Figure 7 As shown, the flushing function detection circuit provided in this application embodiment also includes a resistor R16 with a resistance of 20KΩ, a resistor R17 with a resistance of 10KΩ, a resistor R18 with a resistance of 10KΩ, and a resistor R19 with a resistance of 1KΩ; as Figure 8 As shown, the flushing function detection circuit provided in this embodiment also includes a 20KΩ resistor R22, a 1KΩ resistor R21, and a 100nF capacitor C11, to serve as a voltage divider and circuit protection. Of course, the flushing function detection circuit can also add necessary electronic components between the resistors according to actual conditions; this embodiment does not impose any limitations on this.

[0092] like Figure 9 As shown, Figure 9 This is a schematic diagram of another optional flushing detection process of the flushing function detection circuit provided in one embodiment of this application, and the specific steps are as follows:

[0093] (1) When the flushing assembly enters the working state, the second signal terminal of the flushing assembly transmits the first electrical signal to the second voltage detection terminal (V_TEST2) of the controller 120, and determines whether the voltage signal received by V_TEST2 meets the preset voltage threshold. For example, the voltage threshold can be set to 5.5V, or it can be adjusted adaptively according to the actual situation. This application embodiment does not limit this. If it meets the requirement (Y), proceed to step (2); if it does not meet the requirement (N), the main signal light 110 and the auxiliary signal light 130 light up at the same time, and the buzzer enters the second working state.

[0094] The second working state of the buzzer can be long buzzing of the buzzer.

[0095] (2) If the second electric signal meets the preset voltage threshold, then it is judged whether the second time detection end (SW2) meets the preset electric level signal. The electric level signal in the embodiment of the application is a low electric level signal, or the electric level signal can also be adjusted to a high electric level signal according to the actual circuit condition. If it meets (Y), step (3) is entered. If it does not meet (N), the auxiliary signal lamp 130 is bright, and the buzzer enters the first working state.

[0096] The first working state of the buzzer can be short buzzing of the buzzer. The first working state and the second working state can be adaptively adjusted according to the actual condition, as long as they are two kinds of buzzer states which are easy to distinguish.

[0097] (4) If the second electric signal meets the preset electric level signal, then it is judged whether the duration of the preset electric level signal meets the preset time threshold. The time threshold can be set according to the actual condition, and the embodiment of the application does not limit this. If it meets (Y), step (5) is entered. If it does not meet (N), the auxiliary signal lamp 130 is bright, and the buzzer enters the first working state.

[0098] (5) Similarly to steps (1) to (4), the signal output by the third signal end of the flushing assembly is detected by the third voltage detection end and the third time detection end of the controller 120. If the detection condition meets (Y), step (6) is entered. If the detection condition does not meet (N), the auxiliary signal lamp 130 is bright, and the buzzer enters the first working state.

[0099] (6) Similarly to steps (2) to (4), since in the pulse flushing mode, the second signal end outputs the signal related to the “water supplement function” of the flushing assembly, and the third signal end outputs the signal related to the “flushing function” of the flushing assembly, that is, after the flushing assembly completes the flushing action, the toilet still needs to be supplemented with water, therefore, the signal output by the second signal end of the flushing assembly still needs to be detected again based on the second voltage detection end and the second time detection end. Since the voltage meeting the preset voltage threshold has been detected according to the second voltage detection end, this does not need to be repeatedly detected, or the electric signal output by the signal end of the flushing assembly is detected based on steps (1) to (4). If the detection condition meets (Y), the main signal lamp 110 is bright. If the detection condition does not meet (N), the auxiliary signal lamp 130 is bright, and the buzzer enters the first working state.

[0100] In some embodiments, as shown in FIG. 1, Figure 10 the controller 120 is connected to the main signal lamp 110, the auxiliary signal lamp 130 and the buzzer 140. Figure 10This is another optional schematic diagram of the flushing function detection circuit provided in one embodiment of this application. The flushing function detection circuit provided in this embodiment of the application further includes a backup power supply module, a first signal backup module, a second signal backup module, and a third signal backup module that are connected to each other. The backup power supply module is used to connect to the backup battery, the first signal backup module is used to connect to the first signal terminal, the second signal backup module is used to connect to the second signal terminal, and the third signal backup module is used to connect to the third signal terminal.

[0101] The backup power module includes a connection terminal CN1. The backup power module connects to the backup battery via the BAT terminal and to the power supply via the VCC terminal. For example... Figure 11 As shown, Figure 11 This application provides an embodiment of a flushing function detection circuit, and also an optional schematic diagram. The VCC terminal is connected to the VBAT terminal of the controller 120 through a 51KΩ resistor R23, a 20KΩ resistor R24, a 1KΩ resistor R25, and a 100nF capacitor C12, so that mains power is supplied when mains power is available, and the controller 120 is powered by a backup battery when the mains power is off.

[0102] Furthermore, such as Figure 10 As shown, the backup power module also includes a diode. The anode of the diode is connected to the backup battery, and the cathode is connected to the main power supply. This design ensures that even if the main power supply fails, the backup battery can still provide stable power support to the entire circuit based on the unidirectional conductivity of the diode. The diode prevents reverse current flow and blocks backflow from the main power supply, thus protecting the backup battery from overcharging or damage.

[0103] In addition, such as Figure 10 As shown, the first signal backup module also includes capacitor C1, resistor R1, resistor R2, and diode D2. The first signal backup module is used for electrical connection to the first signal terminal. The second signal backup module is used for electrical connection to the second signal terminal. The second signal backup module is constructed using electronic components similar to those in the first signal backup module, and will not be described in detail here.

[0104] like Figure 12 As shown, Figure 12 This is an optional schematic diagram of a flushing function detection circuit provided in one embodiment of this application. Figure 12 The diagram shows the third signal backup module, which is used to electrically connect to the third signal terminal. The third signal backup module includes capacitors C1, C4, C5, and C6, resistors R5 and R6, diode D4, and Zener diode U1. Among them, the capacitors are used for filtering, the resistors are used for voltage division, the diodes are used to prevent current backflow, and the Zener diode is used to stabilize the output voltage.

[0105] Thus, in addition to being able to detect the good or bad of the flushing assembly through the controller 120, other components can also be accessed through the terminal C2, the terminal C3 and the terminal C4 to perform more detailed detection operations on the flushing assembly

[0106] In some embodiments, the application also provides a smart toilet, and the flushing function detection circuit mentioned above can be arranged in the smart toilet to improve the detection efficiency of the flushing function assembly of the smart toilet.

[0107] It should also be understood that various embodiments provided by the embodiments of the application can be combined arbitrarily to achieve different technical effects.
