[0022] With the rapid development of technology, smart home products are gradually changing people's lifestyles. Among them, smart toilets, as an important part of modern home life, are developing towards a more intelligent and user-friendly direction. However, traditional smart toilets have some inherent limitations in sensing and control technologies, especially in a special environment such as a bathroom, where these limitations are particularly obvious. Traditional smart toilets mostly use infrared sensors for intelligent control, such as functions like automatic lid opening and automatic flushing. However, infrared sensors are easily interfered by various factors in actual applications, such as various heat sources, light sources, radio frequency radiation and hot airflows in the bathroom, as well as problems such as the blocking of human infrared radiation by clothes or bath towels. In addition, when the ambient temperature is close to the human body temperature, the detection and sensitivity of the infrared detector will significantly decrease, even leading to sensing failure, seriously affecting the user experience.

[0023] In view of this, an embodiment of the present application provides an intelligent toilet. This intelligent toilet combines the advantages of radar sensing technology and capacitive sensing technology. Through the sensing component, it can accurately sense the distance value (position) of the target human body, etc., so as to realize the intelligent control of the toilet functions according to the distance value (position) of the target human body. In addition, the radar sensing technology of the sensing component also has good anti-interference ability and can work stably in the complex environment of the bathroom. At the same time, the capacitive sensing technology of the capacitive sensor can ensure that the sensitivity, stability, reliability, etc. of the intelligent toilet will not change due to changes in environmental conditions or long-term use, and has the ability of waterproof and strong anti-interference. After the sensing component detects that the target human body is in the sensing area and generates a corresponding signal, the main control component can receive the signal and control the driving component according to the signal to control the operation state of the toilet, so that the intelligent toilet has a higher level of intelligence, can better meet the needs of users, and thus improve the user experience.

[0024] The following further elaborates on the embodiments of the present application in conjunction with the accompanying drawings.

[0025] See Figure 1 , Figure 1 which is a schematic structural diagram of the intelligent toilet provided by the embodiment of the present application. The intelligent toilet includes a toilet body 110, a sensing component 120, a capacitive sensor 130, a main control component 140, and a driving component 150. Among them, the capacitive sensor 130, the main control component 140, and the driving component 150 are all arranged on the toilet body 110, and the sensing component 120 is installed on the lower side of the toilet body 110. The sensing component 120, the capacitive sensor 130, and the driving component 150 are respectively connected to the main control component 140. Specifically, the sensing component 120 includes a microwave sensing module 121 and a foot sensing module 122. The microwave sensing module 121 can be used to detect the distance value from the target human body and generate an electrical signal according to the distance value. The foot sensing module 122 can be used to generate an action signal according to the foot movement of the target human body. The capacitive sensor 130 can be used to sense the target human body information and generate a command signal according to the sensed information. In addition, the control component 140 can be used to control the operation state of the toilet body 110 through the driving component 150 according to the electrical signal or the action signal, and turn on or off the power supply according to the command signal.

[0026] In a feasible embodiment, when the target human body approaches the toilet, without any contact or operation, the microwave induction module 121 can immediately detect the approach of the target human body and measure the distance between the target human body and the toilet. As the target human body gradually approaches, the microwave induction module 121 can generate corresponding electrical signals according to the distance value between the target human body and it, and transmit them to the main control component 140. At the same time, the foot induction module 122 installed under the toilet also starts to work. When the feet of the target human body touch the induction area, the foot induction module 122 can generate action signals according to the actions of the feet and transmit them to the control component 140. The capacitive sensor 130 can generate command signals by sensing the electric field change of the target human body. After this command signal is received by the main control component 140, it can be used to judge whether to turn on the power of the toilet. The main control component 140 can make a comprehensive judgment according to the received electrical signals, action signals and command signals, and decide the operating state of the toilet. For example, when the main control component 140 judges that the target human body is about to use the toilet, it can activate the toilet lid opening function through the driving component 150 to automatically open the toilet seat ring. In addition, since the capacitive sensor 130 senses the presence of the target human body, the main control component 140 can also turn on the power of the toilet to make it enter the standby state. Therefore, when the target human body needs to use other functions of the toilet (such as flushing, drying, etc.), the toilet can immediately respond and perform corresponding operations.

[0027] In a feasible embodiment, after the target human body finishes using the toilet, the flushing function can be triggered by simply touching the foot induction module 122 with the foot. At the same time, since the microwave induction module 121 detects that the target human body has left the toilet by a certain distance, the main control component 140 judges that the toilet no longer needs to maintain the standby state, and can disconnect the power of the toilet through the driving component 150, thus achieving an energy-saving effect.

[0028] In a feasible embodiment, as Figure 2 shown, the toilet body 110 can be provided with an induction control circuit. Among them, the induction control circuit includes a sensing module 210, a main control module 220 and a driving module 230, and the sensing module 210, the main control module 220 and the driving module 230 are connected in sequence.

[0029] In a feasible embodiment, the sensing module 210 includes a foot induction unit 211. The foot induction unit 211 includes a first interface group 10, a resistor R1, a resistor R2, a capacitor C1 and a diode G. The first interface group 10 includes pins A1, A2 and A3. As Figure 2As shown, pin A1 is connected to the negative electrode of diode G. One end of resistor R1 is connected to pin A3, and the other end is connected to the positive electrode of diode G. One end of resistor R2 is connected to resistor R1, and the other end is connected to capacitor C1. Capacitor C1 is connected to the main control module 220, and pin A2 is grounded. When the foot of the target person touches the sensing area of the foot sensing unit 211, the foot sensing unit 211 can generate an action signal according to the movement of the foot and transmit it to the main control module 220.

[0030] In a feasible embodiment, as Figure 2 shown, the main control module 220 includes a Foot_Key interface. The foot sensing unit 211 can be connected to the main control module 220 through the Foot_Key interface, so that the action signal can be transmitted to the main control module 220 through the Foot_Key interface, enabling the main control module 220 to determine the operating state of the toilet according to the action signal.

[0031] In a feasible embodiment, the sensing module 210 further includes a microwave sensing unit 212. The microwave sensing unit 212 includes a second interface group 20, capacitor C2, capacitor C3, resistor R3, resistor R4, resistor R5, and resistor R6. The second interface group 20 includes pins B1, B2, B3, and B4. As Figure 2 shown, one end of resistor R3 is connected to pin B3, and the other end is connected to the main control module 220; one end of resistor R4 is connected to pin B4, and the other end is connected to capacitor C2; one end of resistor R5 is connected to pin B1, and the other end is connected to resistor R3; one end of resistor R6 is connected to resistor R5, and the other end is connected to the main control module 220. One end of capacitor C3 is connected to the main control module 220, and the other end is connected to capacitor C2. When the target person gradually approaches the toilet, the microwave sensing unit 212 can generate a corresponding electrical signal according to the distance value between the target person and it and transmit it to the main control module 220.

[0032] In a feasible embodiment, as Figure 2 shown, the main control module 220 is provided with an RXD1 interface and a TXD1 interface. The microwave sensing unit 212 can be connected to the main control module 220 through the RXD1 interface and the TXD1 interface, so that the electrical signal can be transmitted to the main control module 220 through the RXD1 interface and the TXD1 interface, enabling the main control module 220 to determine the operating state of the toilet according to the electrical signal.

[0033] In a feasible embodiment, as Figure 2As shown, the driving module 230 includes a third interface group 30, a resistor R7, and a capacitor C4. Among them, the third interface group 30 includes a pin M1, a pin M2, a pin M3, a pin M4, and a pin M5. The pin M1 and the pin M2 are connected to the main control module 220; one end of the resistor R7 is connected to the pin M4, and the other end is connected to the main control module 220; one end of the capacitor C4 is connected to the main control module 220, and the other end is grounded.

[0034] In a feasible embodiment, as Figure 2 shown, the main control module 220 is provided with a Ring_Motor+ interface, a Ring_Motor- interface, and a Ring_Sensor interface. The driving module 230 can be connected to the main control module 220 through the Ring_Motor+ interface, the Ring_Motor- interface, and the Ring_Sensor interface, so that the main control module 220 can control the operating state of the toilet through the driving module 230 according to the electrical signal or the action signal.

[0035] In a feasible embodiment, the toilet body 110 further includes a function operation panel. When the distance value is less than the preset distance threshold, the control component 140 turns on the power supply, and the function operation panel enters the standby state. Specifically, since the capacitive sensor 130 can generate an instruction signal by sensing the electric field change of the target human body, the control component 140 can turn on or off the power supply according to the instruction signal after receiving the instruction signal. Therefore, when the capacitive sensor 130 senses that the target human body is approaching and the distance value between the target human body and the toilet is less than the preset distance threshold, the capacitive sensor 130 can send an instruction signal to the control component 140, so that the control component 140 turns on the power supply and places the function operation panel in the standby state. It should be noted that the preset distance threshold can be determined according to the user's usage habits or the actual size of the toilet. For example, the preset distance threshold can be set to 0.5 meters, which means that when the user is less than 0.5 meters away from the toilet, the toilet will make corresponding responses. The specific value of the preset distance threshold is not limited here.

[0036] In a feasible embodiment, the function operation panel is the control panel of the intelligent toilet and can include various function buttons and indicator lights for controlling various functions of the toilet. When the function operation panel is in the standby state, the function operation panel will wait for further operations by the user. When the user presses a certain button, the control panel will convert this operation into a corresponding control signal and send it to the control component 140. The control component 140 can control the corresponding functions of the toilet according to this control signal, such as flipping the lid, flushing, etc.

[0037] In a feasible embodiment, in order to achieve effective control of the toilet, the control component 140 may also receive some feedback signals, which can come from various sensors and actuators of the toilet, such as temperature sensors and water level sensors. The control component 140 can process and compare these feedback signals, and adjust the output of the control signal in real time to ensure the stability and accuracy of the toilet.

[0038] In a feasible embodiment, the toilet body 110 is also provided with a flushing module, which can be connected to the main control component 140. The flushing module can be used to receive the flushing instruction from the main control component 140 and execute the flushing function.

[0039] In a feasible embodiment, the flushing module includes a large flushing valve, a water inlet valve and an emergency flushing unit. It can be understood that the large flushing valve can be used in scenarios that require strong flushing. For example, when there is a large amount of solid waste, the large flushing valve can generate a large water flow pressure to ensure the flushing effect; the water inlet valve can control the inflow of water and adjust the water inflow according to the instruction of the main control component 140. In case of an emergency or when a quick response is needed, the emergency flushing unit can be immediately activated to provide a temporary flushing function.

[0040] In a feasible embodiment, after the main control component 140 sends the flushing instruction to the flushing module, the flushing module can select and execute the corresponding operations of the large flushing valve, the water inlet valve or the emergency flushing unit according to the type and content of the instruction.

[0041] In a feasible embodiment, after the flushing is completed, the flushing module can send a feedback signal to the main control component 140 to inform the flushing result and the current state of the toilet. The main control component 140 can perform corresponding processing according to the feedback signal, such as closing the water inlet valve, resetting the system, etc.

[0042] In a feasible embodiment, the toilet body 110 also includes a rear seat, an upper cover and a base. The rear seat is arranged on the base, the rear seat is connected to the upper cover, and the sensing component 120 can be arranged on the base. When the target person approaches the toilet base, the sensing component 120 can detect the approach of the target person, measure the distance between the target person and the toilet, and generate a corresponding electrical signal according to the distance value between the target person and it, and then transmit the electrical signal to the main control component 140, so that the main control component 140 can determine the operating state of the toilet according to the electrical signal.

[0043] In a feasible embodiment, the sensing component 120 can be sleeved in a cylindrical shell, and then the cylindrical shell can be installed on the base of the toilet. By sleeving the sensing component 120 in the cylindrical shell, the overall appearance of the toilet can be made more concise, and at the same time, the occupied space can be reduced. At the same time, it also helps to hide and protect the sensing component 120, reduce the interference and damage from the outside, and thus extend the service life of the sensing component 120.

[0044] The foregoing description of the disclosed embodiments enables those skilled in the art to practice or use the present application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application.
