[0033] Figure 5 This is a structural schematic diagram of another smart toilet provided in the embodiments of this application. Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0035] This application provides a smart toilet that can improve the flexibility of the smart toilet.

[0036] Figure 1 This is a structural schematic diagram of a smart toilet provided in an embodiment of this application. Figure 1 As shown, the smart toilet includes a main controller, a seat ring, 2N first sensors, a seat ring controller, a nozzle, and a nozzle motor, where N is an integer greater than 1.

[0037] 2N first sensors are symmetrically distributed on the seat ring. The seat ring controller is connected to the 2N first sensors and the main controller. The main controller is also connected to the nozzle motor.

[0038] 2N first sensors are used to detect signals to obtain 2N signals;

[0039] Seat ring controller, used to send 2N signals to the main controller;

[0040] The main controller is used to determine the user's seat position on the seat ring based on 2N signals, and to control the nozzle motor to operate based on the seat position in order to control the spray angle of the nozzle.

[0041] The 2N first sensors can detect signals in real time and obtain 2N signals, which can then be sent to the seat ring controller.

[0042] The 2N first sensors can also periodically detect signals to obtain 2N signals, which can then be sent to the seat ring controller.

[0043] The 2N first sensors can also detect signals under the control of the seat ring controller. For example, when the seat ring is in the lowered state, the seat ring controller can control the 2N first sensors to detect signals and obtain 2N signals, which can then be sent to the seat ring controller. Similarly, when the user is seated on the seat ring, the seat ring controller can control the 2N first sensors to detect signals and obtain 2N signals, which can then be sent to the seat ring controller. It is evident that the seat ring controller can control the first sensors to collect signals based on the state of the seat ring or the user's use of the smart toilet, avoiding signal collection when it is not needed, reducing unnecessary data collection and processing, and thus lowering the power consumption of the smart toilet.

[0044] The seat ring controller can directly send the 2N signals detected by the 2N first sensors to the main controller. Since the seat ring controller does not need to process the 2N signals detected by the 2N first sensors, the performance requirements for the seat ring controller can be reduced, allowing the use of a lower-performance seat ring controller and thus reducing costs.

[0045] The seat ring controller can also send 2N signals detected by the 2N first sensors to the main controller under certain conditions. For example, when a user is sitting on the seat ring, the seat ring controller can send 2N signals detected by the 2N first sensors to the main controller.

[0046] It is evident that the seat controller only sends the 2N signals detected by the 2N first sensors to the main controller under certain conditions, which avoids unnecessary signal transmission and processing, thereby reducing the power consumption of the smart toilet.

[0047] After receiving 2N signals detected by the 2N first sensors, the main controller can determine the user's sitting position on the seat ring based on the 2N signals. Then, it can control the nozzle motor to work based on the sitting position to drive the nozzle to rotate and control the spray angle of the nozzle.

[0048] The 2N first sensors can be symmetrically distributed across the entire seat ring to accurately determine the user's seating position across the entire seat ring, thereby accurately controlling the spray angle of the nozzles.

[0049] The 2N first sensors can also be symmetrically distributed in the front half of the seat ring.

[0050] When using a smart toilet, users usually sit in the front part of the seat. Therefore, 2N first sensors can be symmetrically set in the front half of the seat, which can reduce the number of first sensors required and thus reduce costs.

[0051] 2N first sensors can be equally spaced on the seat ring to accurately determine the user's sitting position on the seat ring, thereby accurately controlling the spray angle of the nozzle.

[0052] The 2N first sensors can also be arranged at non-equidistant intervals on the seat ring. Different intervals can be used at different locations depending on the probability of the user sitting down. First sensors can be arranged at smaller intervals in locations with a higher probability of user sitting down, and at larger intervals in locations with a lower probability of user sitting down. This reduces the number of first sensors while maintaining accuracy in determining the seating position, thereby reducing costs.

[0053] For example, Figure 2 This is a schematic diagram illustrating the configuration of a first sensor according to an embodiment of this application. Figure 2 As shown, the six first sensors are symmetrically and equally spaced in the front half of the seat ring.

[0054] In some embodiments, the first sensor is a pressure sensor, and the 2N signals are 2N pressure signals.

[0055] The main controller can first select the effective pressure signal from 2N pressure signals, and then determine the user's sitting position on the seat ring based on the effective pressure signal. Based on the sitting position, the controller can control the nozzle motor to work and control the spray angle of the nozzle.

[0056] The main controller can select the effective pressure signal from 2N pressure signals, based on the pressure value exceeding a pressure threshold. Then, it determines the user's seating position on the seat ring based on the location of the pressure sensor corresponding to the effective pressure signal. This seat position determines the user's buttock position, which in turn controls the nozzle motor. Therefore, by adjusting the nozzle's spray angle according to the user's seating position, the system ensures that the user's buttocks are cleaned regardless of their seating position, thus improving the flexibility of the smart toilet's cleaning function.

[0057] The seat controller can first determine whether there is a pressure signal with a corresponding pressure value greater than the pressure threshold among 2N pressure signals. If there is a pressure signal with a corresponding pressure value greater than the pressure threshold among 2N pressure signals, it indicates that a user has sat on the seat and can send 2N pressure signals to the main controller. This can avoid transmitting signals when there is no user sitting on the seat, thereby reducing the power consumption of the smart toilet.

[0058] In some embodiments, the pressure sensor is a capacitive pressure sensor, and the 2N signals are 2N capacitive signals;

[0059] The main controller is specifically used to determine the user's seat position on the seat ring based on the capacitor signal whose corresponding capacitance value is greater than the capacitance threshold among 2N capacitor signals.

[0060] When the pressure sensor is a capacitive pressure sensor, the 2N signals are 2N capacitive signals.

[0061] The main controller first selects a capacitor signal from 2N capacitor signals whose capacitance value is greater than a capacitance threshold. Then, based on the position of the pressure sensor corresponding to the selected capacitor signal, it determines the user's sitting position on the seat ring. Based on this seat position, it determines the user's buttock position and, consequently, controls the nozzle motor accordingly. Therefore, by adjusting the nozzle's spray angle based on the user's sitting position, it ensures that the user's buttocks are cleaned regardless of how they sit, thus enhancing the flexibility of the smart toilet.

[0062] The seat controller can first determine whether there is a capacitor signal with a corresponding capacitance value greater than the capacitance threshold among the 2N capacitor signals. If there is a capacitor signal with a corresponding capacitance value greater than the capacitance threshold among the 2N capacitor signals, it indicates that a user has sat on the seat and can send 2N capacitor signals to the main controller. This can avoid transmitting signals when there is no user sitting on the seat and can reduce the power consumption of the smart toilet.

[0063] When a capacitive pressure sensor detects a person sitting down, its capacitance value changes. The capacitance value differs depending on whether a user is detected on the seat or not. The main controller can determine the presence of a user based on the capacitance value corresponding to the capacitance signal. The main controller can preset a capacitance threshold and compare it with the capacitance value detected by the capacitive pressure sensor. If the detected capacitance value is greater than or equal to the capacitance threshold, a user is confirmed to be seated; if the detected capacitance value is less than the capacitance threshold, no one is seated.

[0064] For example, such as Figure 2 As shown, when the capacitance values ​​corresponding to the capacitance signals collected by sensors 1, 2, 5, and 6 are greater than the capacitance threshold, the difference in capacitance values ​​between sensors 1 and 6 can be determined, yielding the first capacitance difference. Similarly, the difference in capacitance values ​​between sensors 2 and 5 can be determined, yielding the second capacitance difference. When both the first and second capacitance differences are within a preset range, it indicates that the hip position is centered, and the main controller can control the nozzle motor to center the nozzle for centered water spraying. When both the first and second capacitance differences are outside the preset range but greater than 0, it indicates that the user's center of gravity is close to sensors 1 and 2, and the main controller can control the nozzle motor to rotate the nozzle towards sensors 1 and 2 at a certain angle for tilted water spraying.

[0065] For example, such as Figure 2 As shown, when the capacitance values ​​corresponding to sensors 3 and 4 are greater than the capacitance threshold, it indicates that the user may be a child. The main controller can control the nozzle motor to center the nozzle so that the nozzle can spray water for cleaning.

[0066] The pressure sensor can also be a piezoresistive pressure sensor or a piezoelectric pressure sensor.

[0067] In some embodiments, the first sensor is a gravity sensor.

[0068] In some embodiments, the 2N signals are 2N gravity signals;

[0069] The main controller is specifically used to determine the user's sitting position on the seat ring based on the difference between the gravity values ​​corresponding to 2N gravity signals.

[0070] The main controller can first determine the corresponding gravity values ​​from 2N gravity signals to obtain 2N gravity values. Then, it can compare the magnitudes of the gravity values ​​corresponding to two symmetrically set gravity sensors and determine the tilt direction of the user's seating position based on the magnitudes of the gravity values ​​corresponding to the two symmetrically set gravity sensors.

[0071] For example, such as Figure 2 As shown, the difference in gravity values ​​between sensor 1 and sensor 6 can be determined to obtain the first gravity difference value. The difference in gravity values ​​between sensor 2 and sensor 5 can be determined to obtain the second gravity difference value. When the first and second gravity differences are within a preset range, it indicates that the hip position is centered, and the main controller can control the nozzle motor to center the nozzle for centered water spraying. When the first and second gravity differences are outside the preset range but greater than 0, it indicates that the user's center of gravity is close to sensor 1 and sensor 2. The main controller can control the nozzle motor to rotate the nozzle towards sensor 1 and sensor 2 at a certain angle for tilted water spraying.

[0072] The seat controller can first determine whether there is a gravity signal with a corresponding gravity value greater than the gravity threshold among 2N gravity signals. If there is a gravity signal with a corresponding gravity value greater than the gravity threshold among the 2N gravity signals, it indicates that a user has sat on the seat and can send 2N gravity signals to the main controller. This can avoid transmitting signals when there is no user sitting on the seat, thereby reducing the power consumption of the smart toilet.

[0073] In some embodiments, the main controller may include a comparator.

[0074] For example, in the case where there are 2N signals, which are 2N capacitance signals, the comparator can compare each capacitance signal with a capacitance threshold.

[0075] In some embodiments, the seat controller may include a comparator.

[0076] In some embodiments, Figure 3 This is a schematic diagram of another smart toilet provided in an embodiment of this application. Figure 3 The smart toilet shown is made of Figure 1 The smart toilet shown is optimized as follows. Figure 3 As shown, the smart toilet also includes a spray bar and a spray bar motor, with the spray bar motor connected to the main controller;

[0077] The main controller is also used to control the operation of the spray boom motor according to the seating position, so as to control the extension and retraction position of the spray boom.

[0078] Different users have different toilet usage habits, so their sitting positions may differ. For example, some users prefer to sit at the front of the seat, while others prefer to sit in the middle.

[0079] Users of different ages or genders have different habits when using the toilet, so their seating positions may differ. For example, children, with their shorter legs, tend to sit at the front of the seat, while adults, with their longer legs, tend to sit in the middle or at the back of the seat.

[0080] Therefore, if the extension and retraction position of the spray bar is the same every time, the water spray may be too far forward or too far back, resulting in a poor user experience.

[0081] Therefore, the main controller can control the spray bar motor to operate based on the user's seating position, driving the spray bar to extend and retract, thereby controlling the extension and retraction position of the spray bar and adjusting the water spray position. It is evident that adjusting the spray bar's extension and retraction position according to the user's seating position ensures accurate cleaning of the user's buttocks regardless of how the user sits, improving the flexibility of the smart toilet and enhancing the user experience.

[0082] In some embodiments, 2N first sensors are symmetrically distributed on the seat ring along the telescopic axis of the spray bar.

[0083] As can be seen, the 2N first sensors are symmetrically distributed on the seat ring along the telescopic axis of the spray bar, which ensures that the first sensors are axially symmetrical.

[0084] In some embodiments, Figure 4 This is a structural schematic diagram of another smart toilet provided in an embodiment of this application. Wherein, Figure 4 The smart toilet shown is made of Figure 3 The smart toilet shown is optimized as follows. Figure 4 As shown, the smart toilet also includes a second sensor, which is connected to the main controller.

[0085] The main controller is used to send control signals to the seat ring controller when it is determined that a user is approaching based on the signal detected by the second sensor.

[0086] Seat ring controller, used to control the operation of 2N first sensors according to control signals.

[0087] The main controller can determine the presence of a user based on the signal detected by the second sensor. If a user is present, it can further determine if another user is approaching based on the signal detected by the second sensor. If a user approaches the smart toilet, it indicates that a user may intend to use the smart toilet, and a control signal can be sent to the seat controller to initiate operation. The second sensor can be an infrared sensor, a microwave radar sensor, or a lidar sensor.

[0088] After receiving the control signal, the seat ring controller can first determine whether the seat ring is in the lowered state. If the seat ring is in the lowered state, it can control 2N first sensors to work, enabling all 2N first sensors to detect signals. If the seat ring is not in the lowered state, it can first control the seat ring to lower, and then control the 2N first sensors to work, enabling all 2N first sensors to detect signals.

[0089] It is evident that the first sensor collects signals only when a user may need to use the smart toilet in order to determine the user's seating position, thus avoiding unnecessary data collection and reducing the power consumption of the smart toilet.

[0090] In some embodiments, Figure 5 This is a structural schematic diagram of another smart toilet provided in an embodiment of this application. Wherein, Figure 5 The smart toilet shown is made of Figure 3 The smart toilet shown is optimized as follows. Figure 5 As shown, the smart toilet also includes an ambient temperature sensor and a water temperature sensor, which are connected to the main controller.

[0091] An ambient temperature sensor is used to detect ambient temperature.

[0092] A water temperature sensor is used to monitor the temperature of the sprayed water;

[0093] The main controller is also used to control the temperature of the sprayed water based on the ambient temperature.

[0094] If the water temperature is not suitable when washing a user's buttocks, it will cause discomfort and reduce the user experience. For example, in winter, if cold water is used for washing, the user will feel cold, resulting in a poor user experience.

[0095] Therefore, the ambient temperature sensor can detect the ambient temperature, and the water temperature sensor can monitor the temperature of the sprayed water. Before controlling the spraying, the main controller can heat the water according to the ambient temperature so that the sprayed water temperature can change with the ambient temperature, which can improve the user experience.

[0096] The main controller can determine the ambient temperature as the water spray temperature. For example, in summer, the ambient temperature can be determined as the water spray temperature.

[0097] The main controller can also determine the water spray temperature by summing the ambient temperature and the preset temperature. For example, in winter, when the ambient temperature is low, the water spray temperature can be determined by summing the ambient temperature and the preset temperature.

[0098] It should be understood that identical, similar, or corresponding content in different embodiments may be referenced to each other.

[0099] It should be understood that the above connection can be interpreted as an electrical connection.

[0100] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this application.

[0101] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
