[0030] A smart toilet is a sanitary device that combines modern technology and convenience. It's typically equipped with various intelligent features to provide a more comfortable and convenient user experience. Typically, a smart toilet seat is equipped with a heater that activates when the user sits down, enhancing the user experience.
[0031] Related technologies use sensor points placed at various locations on toilet seats to detect when a user sits down. However, this method requires high accuracy in determining the user's seat position. For example, if the user is a child or elderly person, their thin legs may not contact the sensor points, causing the smart toilet to fail to activate the seat heating function. Consequently, related technologies suffer from low accuracy in detecting when a user sits down.
[0032] The following combination Figures 1 to 3 , further elaborating on the embodiments of the present application, wherein each structure Figures 1 to 3 All of them are mentioned in.
[0033] The embodiment of the present application provides a toilet seat, a smart cover, and a smart toilet, wherein the toilet seat includes:
[0034] The upper shell 110 and the lower shell 120 are connected to form a seat ring cavity therebetween;
[0035] The conductive component 130 is closed and arranged in a surrounding manner in the seat ring cavity;
[0036] A control chip 140 , comprising a first control pin 141 and a second control pin 142 , wherein the first control pin 141 is electrically connected to the conductive component 130 ;
[0037] The heating component 150 is attached to the upper housing 110 and is electrically connected to the second control pin 142 ;
[0038] Among them, the control chip 140 outputs a first electrical signal through the first control pin 141 to charge the conductive component 130, and generates a time signal after the conductive component 130 reaches electrical balance. After the control chip 140 compares and obtains that the time signal is different from the preset signal, it sends a second electrical signal to the heating component 150 through the second control pin 142 to put the heating component 150 into working state.
[0039] like Figure 1 As shown, Figure 1 The figure is a schematic diagram of the structure of a toilet seat provided by one embodiment of the present application. The toilet seat includes an upper shell 110 and a lower shell 120. When the upper shell 110 and the lower shell 120 are connected, a seat cavity is formed between them. The components used in the embodiment of the present application can be placed in the seat cavity to achieve the corresponding functions. The upper shell 110 and the lower shell 120 can be made of materials such as polypropylene (PP), polyethylene (PE), and polyacrylate (ABS). The embodiment of the present application does not limit the specific materials of the upper shell 110 and the lower shell 120 of the toilet seat, and can be set according to actual conditions.
[0040] like Figure 2 As shown, Figure 2 This is a module schematic diagram of a toilet seat provided in an embodiment of the present application, wherein a control chip 140 is provided in the seat cavity, and the control chip 140 is connected to the conductive component 130 and the heating component 150 to sense the user's sitting situation through the conductive component 130, and turn on the heating component 150 when it is determined that the user is sitting, so that the heating component 150 enters the working state.
[0041] Combine Figure 1 、 Figure 2As can be seen, the conductive component 130 is connected to the control chip 140 and is disposed in a closed, encircling configuration within the seat cavity. In some embodiments, the conductive component 130 is a metal wire, which is disposed along the edges of the upper shell 110 and the lower shell 120. With this connection method, the metal wire can be inductively heated using a high-frequency induction machine during toilet seat production. In this case, the heated metal wire is just enough to weld the upper shell 110 and the lower shell 120 of the toilet seat. In addition, the cost of metal wire is extremely low, so the embodiments of the present application can achieve good detection results while reducing production costs.
[0042] It should be noted that, in addition to being a metal wire, the conductive component 130 can also be a component that can realize conductive induction, such as metal copper foil, conductive plastic or polymer, conductive coating, carbon nanotube, conductive rubber, liquid conductive medium, etc. The specific setting can be based on actual conditions, and the embodiment of the present application does not impose any restrictions.
[0043] It should be noted that the control chip 140 model selected in the embodiment of the present application is PIC12F615. It can be understood that the control chip 140 integrates multiple functional components such as an arithmetic unit, a controller, a memory, and an input / output device to realize functions such as signal comparison processing, control, and storage. For example, the arithmetic unit includes a comparison operator, which can perform logical operations on two newly generated signals, or on a newly generated signal and a preset signal, and then determine the control signal based on the comparison result to turn on or off the corresponding function. Of course, the specific model of the control chip 140 can be adjusted according to actual conditions, and the embodiment of the present application does not limit it.
[0044] like Figure 3 As shown, Figure 3 This is a schematic diagram of the circuit structure of a toilet seat provided in an embodiment of the present application. Specifically, the control chip 140 selected in the embodiment of the present application includes 8 pins, among which the first control pin 141 (pin 5) is directly connected to the conductive component 130, and the second control pin 142 (pin 3) is directly electrically connected to the heating component 150.
[0045] like Figure 1 As shown, the heating component 150 is arranged around the seat ring cavity and is usually arranged adjacent to the upper shell 110. In this way, when the heating component 150 enters the working state, the heat can be quickly transferred to the user through the upper shell 110, thereby achieving a good heating function of the toilet seat with minimal heat.
[0046] Furthermore, to improve the stability of component installation, the conductive component 130 and the heating component 150 installed in the seat ring cavity can be fixed by a fixing member. The fixing member can be double-sided tape, which is highly practical, low-cost, and easy to replace. Alternatively, the fixing member can be an adhesive, a joint, or other fixing component. The specific selection can be based on actual conditions and is not limited by this application.
[0047] Among them, the heating component 150 can be a heating component 150 that can generate heat, such as an electric heating wire, an aluminum foil heating sheet, a flexible heating film, a silicone heating sheet, etc., and can be specifically set according to actual conditions, and the embodiment of the present application does not limit it.
[0048] In some embodiments, a first resistor is further disposed in the seat ring cavity, one end of the first resistor is electrically connected to the conductive component 130 , and the other end of the first resistor is electrically connected to the first control pin 141 .
[0049] like Figure 3 As shown, in addition to being directly connected to the conductive component 130, the first control pin 141 can also be first connected to the first resistor R5, and then the first resistor R5 is connected to the conductive component 130. The first resistor R5 can act as a voltage divider to control the magnitude of the current flowing into the conductive component 130, and at the same time, protect the more sensitive control chip 140 from being damaged by excessive current.
[0050] In some embodiments, a transistor and a second resistor are also provided in the seat ring cavity, the first end of the transistor is electrically connected to one end of the second resistor, the second end of the transistor is electrically connected to the heating component 150, and the third end of the transistor is grounded; the other end of the second resistor is electrically connected to the second control pin 142.
[0051] In addition to being directly connected to the heating component 150, the second control pin 142 can also be first connected to the second resistor R2 and the transistor, and then connected to the heating component 150 through the transistor. The transistor includes three terminals: a first terminal being a base, a second terminal being a collector, and a third terminal being an emitter. That is, the base is connected to one terminal of the second resistor R2, the collector is connected to the heating component 150, and the emitter is grounded. The embodiment of the present application can drive the working state of the heating component 150 by driving the transistor. The transistor has a simple structure and is easy to install. At the same time, the transistor can also protect the control chip 140 from burning out, thereby extending the service life of the toilet seat.
[0052] Or, as Figure 3As shown, the collector of the transistor can be electrically connected to the heating component 150 through the connecting terminal J2. One end (end 1) of the connecting terminal J2 is used to connect to an external power supply, for example, the external power supply can be 12 volts (V) or 24V; the other end (end 2) is used to connect to the collector of the transistor; and the other end (not shown in the figure) is used to connect to the heating component 150. On the one hand, the connecting terminal can facilitate the plugging and unplugging of the heating component 150, improve the installation convenience and maintainability of the heating component 150, and eliminate the need for complicated welding or disassembly work; on the other hand, the connecting terminal usually has a reliable connection structure and sealing performance. Therefore, the connecting terminal can withstand large electrical loads and mechanical stresses, thereby ensuring the stability and safety of the electrical connection.
[0053] In some embodiments, a fourth resistor is further disposed in the seat ring cavity, one end of the fourth resistor is electrically connected to the third control pin, and the other end of the fourth resistor is grounded.
[0054] like Figure 3 As shown, in addition to being directly connected to one end of the second resistor, the first end of the transistor can also be connected to a fourth resistor R3 by setting it in the seat ring cavity. Furthermore, one end of the fourth resistor R3 is connected to the third control pin of the control chip 140 and the base of the transistor through a shunt, and the other end of the fourth resistor R3 is grounded.
[0055] It should be noted that the transistor model selected in the embodiment of the present application is STU9916. The specific model of the transistor can be adjusted according to actual conditions, and the embodiment of the present application does not impose any limitation.
[0056] Furthermore, pin 1 of the control chip 140 is used to connect to a 5V voltage, pin 6 of the control chip 140 is used for grounding, and pin 4 of the control chip 140 can be connected to other functional components according to actual conditions, and this embodiment of the present application does not impose specific limitations. The control chip 140 outputs a first electrical signal through the first control pin 141 (pin 5) to charge the conductive component 130 until the electrical energy can no longer be transmitted. A stable induced electric field is formed around the conductive component 130, and the conductive component 130 reaches electrical equilibrium. At this time, the control chip 140 generates a corresponding time signal. It can be understood that when no user is seated, the control chip 140 will generate a corresponding first time signal within the first time, and record the first time signal as a preset signal. The control chip 140 can store the time corresponding to the preset signal in the memory; since the user is a conductor, when a user is seated, the user will take away part of the charge in the metal wire. When the conductive component 130 reaches electrical balance again, the control chip 140 will generate a corresponding time signal within the second time; then, the control chip 140 will compare the time signal with the preset signal. Since the second time is usually greater than the first time, when the comparator determines that there is a difference between the time signal and the preset signal, it is determined that the user is seated; at this time, the control chip 140 sends a second electrical signal to the heating component 150 through the second control pin 142 to drive the heating component 150 into working state.
[0057] Because the conductive component 130 is disposed within the seat cavity, the charge in the conductive component 130 is attracted to the user regardless of where they sit. Compared to the related art, which deploys multiple sensing points to detect the user's seating position, the embodiment of the present application can achieve comprehensive detection of all positions on the toilet seat, thus providing better and more universal detection of user seating. Furthermore, the sensing components used in the related art are mostly made of rigid materials, suitable for sensing small areas. The metal wire used in the embodiment of the present application is relatively flexible and can be placed around the toilet seat, resulting in higher detection sensitivity.
[0058] In some embodiments, a vibration sensor 170 is further provided in the seat ring cavity, and the control chip 140 is connected to the vibration sensor 170 via a third control pin.
[0059] like Figure 1 、 Figure 2 and Figure 3 As shown, in the embodiment of the present application, a vibration sensor 170 is further provided in the seat cavity of the toilet seat, and the third control pin (pin 2) of the control chip 140 is connected to the vibration sensor 170. The control chip 140 can control the heating component 150 to enter a corresponding heating state of different levels according to the vibration signal of different intensities received by the vibration sensor 170.
[0060] Furthermore, the third control pin (pin 2) of the control chip 140 is also connected to one end of the resistor R1, and the other end of the resistor R1 is grounded. The resistor R1 plays a role in regulating and protecting the connection between the vibration sensor 170 and the control chip 140 to ensure that the electrical signal can be correctly transmitted and processed, while protecting the associated circuit from damage.
[0061] In some embodiments, a temperature detection component 160 is also provided in the seat ring cavity, one end of the temperature detection component 160 is electrically connected to the fourth control pin of the control chip 140, and the other end of the temperature detection component 160 is grounded. The temperature detection component 160 is provided on the heating component 150.
[0062] like Figure 2 and Figure 3 As shown, in the embodiment of the present application, a temperature detection assembly 160 is further disposed within the seat cavity of the toilet seat. The fourth control pin (pin 7) of the control chip 140 can be directly connected to one end of the temperature detection assembly 160, and the other end of the temperature detection assembly 160 is grounded. The temperature detection assembly can sense temperature changes of the heating component 150 or the surrounding environment in real time and transmit the temperature data to the control chip 140, so that the control chip 140 can accurately grasp the current temperature conditions and effectively adjust the heating component 150.
[0063] Among them, the temperature detection component 160 can be a detection resistor RS. Further, the detection resistor RS can be a chip thermistor (NTC). In this way, the temperature detection component 160 can be integrated with the control chip 140 without the need for additional wire connection, thereby reducing the cost of the toilet seat and increasing the simplicity of the toilet seat installation.
[0064] In some embodiments, a voltage stabilizing chip is also provided in the seat ring cavity, the first end of the voltage stabilizing chip is electrically connected to the external power supply through the first filter circuit, the second end of the voltage stabilizing chip is electrically connected to the fifth control pin of the control chip 140 through the second filter circuit, the third end of the voltage stabilizing chip is grounded, and the first filter circuit and the second filter circuit both include at least one capacitor.
[0065] like Figure 2 and Figure 3As shown, in the embodiment of the present application, a voltage stabilizing unit 180 is further provided in the seat cavity of the toilet seat. The voltage stabilizing unit 180 includes a voltage stabilizing chip, which includes an input terminal (first terminal), an output terminal (second terminal), and a ground terminal (third terminal). The input terminal of the voltage stabilizing chip is connected to a first filter circuit, which includes capacitors C1 and C2 connected in parallel. The first filter circuit is connected to an external power supply via a connection terminal J1. The output terminal of the voltage stabilizing chip is connected to a second filter circuit, which includes capacitors C3 and C4 connected in parallel. The second filter circuit is also connected to the fifth control pin (pin 8) of the control chip 140. Capacitors C2 and C3 can also be connected to an external power supply to provide a certain degree of power supply stability when the power supply voltage fluctuates or the load changes temporarily.
[0066] Furthermore, the voltage stabilizing chip can effectively filter out clutter in the circuit by controlling the first filtering circuit and the second filtering circuit, thereby improving the stability of the power supply and meeting the voltage stability and reliability requirements of various components.
[0067] In some embodiments, a third resistor is further provided in the seat ring cavity, one end of the third resistor is electrically connected to the temperature detection component 160, and the other end of the third resistor is electrically connected to the third end of the voltage stabilizing chip.
[0068] Furthermore, the voltage stabilizing unit 180 can also be connected to the temperature detection component 160 via a third resistor R4. The third resistor R4 can transmit the electrical signal transmitted by the temperature detection component to the voltage stabilizing chip in the voltage stabilizing unit 180. The voltage stabilizing chip adjusts its output characteristics based on the received electrical signal to offset the impact of temperature changes on the voltage stabilizing unit 180, thereby achieving a response to ambient temperature changes. This allows the voltage stabilizing unit 180 to maintain a stable output under different operating conditions and adapt to various application requirements.
[0069] It should be noted that the voltage stabilizing chip model selected in the embodiment of the present application is 78LO5. The specific model of the voltage stabilizing chip can be adjusted according to actual conditions, and the embodiment of the present application does not impose any restrictions.
[0070] In some embodiments, the present application further provides a smart cover. The specific type of the smart cover can be set according to actual conditions and is not limited by the present embodiment. The smart cover can be rotatably connected to the toilet seat provided in the embodiment of the present application. When the smart cover is opened, the toilet seat can achieve high-accuracy detection of the user sitting down.
[0071] In some embodiments, the present application also provides a smart toilet, which includes a smart toilet body and the toilet seat mentioned above to improve the accuracy of the smart toilet in detecting when a user sits down.
[0072] It should also be understood that the various implementation methods provided in the embodiments of the present application can be combined arbitrarily to achieve different technical effects.
[0073] The above is a specific description of the preferred implementation of the present application, but the present application is not limited to the above implementation mode.
