The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0052] Nowadays, toilets are very common living facilities in every household, which bring great convenience to people's lives. When people use the toilet in cold weather, if the toilet does not have a heating function, it will seriously affect the use experience. And if economic and simple accessories such as toilet seat pads are used, there are also problems such as inconvenience in use and being easy to get dirty and difficult to clean.

[0053] At present, for the toilet seat with a heating function, there is a problem that the toilet seat cannot be heated when there is a power outage.

[0054] Based on this, the embodiments of this application propose a power supply control circuit. By setting an energy storage module in the power supply control circuit, it can control the energy storage module to supply power to the heating wire in the event of a power outage, without affecting the normal use of the seat heating function.

[0055] Refer to Figure 1 , Figure 1 is a schematic diagram of the internal structure of a toilet seat provided by an embodiment of this application. As shown by Figure 1 , the toilet seat includes a seat body 1, a heating wire 11 arranged inside the seat, and a power supply control circuit 12. Among them, the heating wire 11 can heat the seat after being powered on. The power supply control circuit 12 is electrically connected to the heating wire 11, and the power supply control circuit 12 can control the power supply to the heating wire 11.

[0056] Refer to Figure 2 , Figure 2 is the first block diagram of the power supply control circuit provided by an embodiment of this application. As shown by Figure 2As shown in the figure, the power supply control circuit includes an AC-DC power module 121, an optocoupler module 122, a first switch 123, a microcontroller 124, and an energy storage module 125. Among them, the first end of the AC-DC power module 121 is used to connect to the mains power 10, the second end of the AC-DC power module 121 is connected to the first end of the first switch 123, and the second end of the first switch 123 is connected to the power input end of the heating wire 11. The first end of the optocoupler module 122 is used to connect to the mains power 10, the second end of the optocoupler module 122 is connected to the first end of the microcontroller 124, and the second end of the microcontroller 124 is connected to the third end of the first switch 123. The first end of the energy storage module 125 is connected between the second end of the first switch 123 and the power input end of the heating wire 11, and the second end of the energy storage module 125 is grounded.

[0057] In the embodiment of the present application, the AC-DC power module 121 can convert alternating current (AC) into direct current (DC). Specifically, the AC-DC power module 121 can convert the mains power, which is an AC power source (such as 110V - 220V), into various DC voltages (such as common 5V, 12V, 24V, 48V, etc.) to adapt to the requirements of the toilet seat heating for specific DC voltage values. The AC-DC power module 121 can also keep the output DC voltage relatively stable under the conditions of input AC power voltage fluctuation, load change, etc., reduce the impact on the backend devices, and ensure the normal working performance of the devices. At the same time, it can also perform processing such as filtering on the rectified DC to reduce the AC components (such as ripple, etc.) and provide a relatively pure DC power supply.

[0058] In the embodiment of the present application, the optocoupler module 122, also known as an opto-isolator, is a device that converts the input signal into an electrical signal output through an optical signal. When detecting the presence of alternating current, the presence or absence of alternating current can be determined by measuring the voltage change across the optocoupler. Specifically, when alternating current passes through, the light-emitting element in the optocoupler module 122 will be activated, emit light, and then trigger the photosensitive element to generate an electrical signal. This electrical signal can be recognized and processed by the microcontroller 124 to determine the presence or absence of alternating current. The optocoupler module 122 is connected to the mains power 10. If alternating current exists, that is, the mains power is normally supplied, the optocoupler module 122 will generate an electrical signal and transmit it to the microcontroller 124. After receiving the electrical signal generated by the optocoupler module 122, the microcontroller 124 can determine the presence of alternating current, that is, it can determine that the mains power is normally supplied. If there is no alternating current, that is, the mains power is out of power, the optocoupler module 122 will not generate an electrical signal, that is, the optocoupler module 122 will not transmit an electrical signal to the microcontroller 124. Since the microcontroller 124 does not receive the electrical signal generated by the optocoupler module 122, it can be determined that there is no alternating current, that is, it can be determined that the mains power is out of power.

[0059] In the embodiment of the present application, the second end of the AC-DC power module 121 is connected to the first end of the first switch 123, the second end of the first switch 123 is connected to the power input end of the heating wire 11, and the first end of the energy storage module 125 is connected between the second end of the first switch 123 and the power input end of the heating wire 11. Therefore, when the first switch 123 is closed, the current and voltage of the commercial power passing through the AC-DC power module 121 can normally supply power to the heating wire 11, and the current and voltage of the commercial power passing through the AC-DC power module 121 can charge the energy storage module 125. When the first switch 123 is opened, the current and voltage of the commercial power passing through the AC-DC power module 121 are disconnected by the first switch 123 and cannot flow to the heating wire 11. At this time, the energy storage module 125 discharges to supply power to the heating wire 11.

[0060] In the embodiment of the present application, the energy storage module 125 can be a super capacitor or an energy storage device. Among them, the super capacitor is also called the farad capacitor or the gold capacitor, and has an ultra-large farad-level capacitance. The super capacitor is a new type of energy storage device, which has the characteristics of short charging time, long service life, good temperature characteristics, energy saving and environmental protection. The super capacitor can store the energy of the separated charges. The larger the area for storing charges and the denser the separated charges, the larger its capacitance. The super capacitor has a strong power output performance and can instantaneously release a large current or high power, playing the function of "peak shaving and valley filling".

[0061] In the embodiment of the present application, the microcontroller 124, also called the microprocessor or MCU, is a highly integrated microcomputer. It integrates key functions such as a central processing unit (CPU), memories (RAM and ROM), various input / output interfaces (I / O), a timer / counter, and an interrupt system on a single chip, forming a complete microcomputer system. In the embodiment of the present application, when the microcontroller 124 receives the electrical signal generated by the optocoupler module 122, that is, when the microcontroller 124 detects the normal supply of the commercial power, it will send a first control signal to the first switch 123 to control the first switch 123 to close, so that the commercial power 10 supplies power to the heating wire 11 and the commercial power 10 charges the energy storage module 125. When the microcontroller 124 does not receive the electrical signal generated by the optocoupler module 122, that is, when the microcontroller 124 detects a power outage of the commercial power, it will send a second control signal to the first switch 123 to control the first switch 123 to open, so that the energy storage module 125 supplies power to the heating wire 11. That is, in the case of a power outage, the microcontroller 124 controls the energy storage module 125 to supply power to the heating wire 11, so that the normal use of the seat ring heating function is not affected even in the case of a power outage.

[0062] In some embodiments, refer to Figure 3 , Figure 3This is the second block diagram of the power supply control circuit provided by an embodiment of the present application. Figure 3 As shown, in addition to the AC-DC power module 121, optocoupler module 122, first switch 123, microcontroller 124, and energy storage module 125, the power supply control circuit further includes a power module 126. Among them, the power module 126 is connected in parallel between the second end of the first switch 123 and the first end of the energy storage module 125. In the embodiment of the present application, when the microcontroller 124 detects a power outage of the mains, it will send a second control signal to the first switch 123 to control the first switch 123 to open. When the first switch 123 is open, the power module 126 can also supply power to the heating wire 11 and charge the energy storage module 125.

[0063] In some embodiments, the power module 126 can be a storage battery or a mobile power bank. When the mains is normally supplied, the mains can also charge the power module 126.

[0064] In some embodiments, referring to Figure 4 , Figure 4 This is the third block diagram of the power supply control circuit provided by an embodiment of the present application. Figure 4 As shown, in addition to the AC-DC power module 121, optocoupler module 122, first switch 123, microcontroller 124, energy storage module 125, and power module 126, the power supply control circuit further includes a charging circuit 127. Among them, the charging circuit 127 is connected between the second end of the AC-DC power module 126 and the first end of the first switch 123. Among them, the charging circuit 127 can charge the energy storage module 125 at a set charging voltage to improve the charging rate of the energy storage module 125.

[0065] In some embodiments, referring to Figure 5 , Figure 5 This is the fourth block diagram of the power supply control circuit provided by an embodiment of the present application. Figure 5 As shown, in addition to the AC-DC power module 121, optocoupler module 122, first switch 123, microcontroller 124, energy storage module 125, power module 126, and charging circuit 127, the power supply control circuit further includes an overcurrent and overvoltage protection module 128. Among them, the overcurrent and overvoltage protection module 128 is connected between the second end of the first switch 123 and the first end of the energy storage module 125. The overcurrent and overvoltage protection module 128 can monitor the current and voltage in the circuit by detecting the magnitude of the current and voltage in the circuit. When the current or voltage value exceeds a certain specified range, the energy storage module 125 is protected by cutting off the circuit. This protection module integrates multiple protection characteristics and can protect the energy storage module 125 and the power supply itself from damage caused by faults or improper settings.

[0066] In some embodiments, referring toFigure 6 , Figure 6 is the fifth block diagram of the power supply control circuit provided by an embodiment of the present application. As shown by Figure 6 , in addition to including an AC-DC power module 121, an optocoupler module 122, a first switch 123, a microcontroller 124, an energy storage module 125, a power module 126, a charging circuit 127, and an overcurrent and overvoltage protection module 128, the power supply control circuit further includes a current detection circuit 129 and an alarm circuit 1210. Among them, both the current detection circuit 129 and the alarm circuit 1210 are connected to the microcontroller 124. The circuit detection circuit 129 is also connected to the first end of the energy storage module 125. The circuit detection circuit 129 is used to detect the discharge current of the energy storage module 125, that is, the circuit detection circuit 129 is used to detect the magnitude of the current formed when the energy storage module 125 discharges the stored electrical energy. The circuit detection circuit 129 is connected to the microcontroller 124 and can transmit the detection signal of the discharge current to the microcontroller 124. The microcontroller 124 can be used to send a third control signal to the alarm circuit 1210 when it detects that the discharge current is less than a preset value, so that the alarm circuit 1210 issues an alarm. Among them, the alarm circuit 1210 can include a sound alarm circuit, an optical alarm circuit, or an acoustic-optic alarm circuit. That is, the alarm circuit 1210 can adopt a sound alarm circuit, which can issue a sound alarm when receiving the third control sent by the microcontroller 124 to remind the user that the electrical energy of the energy storage module 125 is low and the power module 126 is needed to charge the energy storage module 125. The alarm circuit 1210 can also adopt an optical alarm circuit, which can issue a light alarm (such as turning on a light or flashing a light) when receiving the third control signal sent by the microcontroller 124 to remind the user that the electrical energy of the energy storage module 125 is low and the power module 126 is needed to charge the energy storage module 125. The alarm circuit 1210 can also adopt an acoustic-optic alarm circuit, which can simultaneously issue a sound and a light alarm when receiving the third control signal sent by the microcontroller 124 to remind the user that the electrical energy of the energy storage module 125 is low and the power module 126 is needed to charge the energy storage module 125.

[0067] In the embodiments of the present application, when the mains power is normally supplied, the mains power can charge the energy storage module 125, enabling the energy storage module 125 to store electrical energy. Thus, when the mains power fails, the energy storage module 125 storing electrical energy can supply power to the heating wire 11, enabling the heating function of the toilet seat to be realized even in the case of a power outage. However, the electrical energy that the energy storage module 125 can store is limited. After the energy storage module 125 discharges to supply power to the heating wire, the electrical energy stored in the energy storage module 125 will be gradually consumed. If the power outage lasts for a long time, the electrical energy stored in the energy storage module 125 will be exhausted. By providing a current detection circuit 129 and an alarm circuit 1210 in the embodiments of the present application, when the current detection circuit 129 detects that the electrical energy stored in the energy storage module 125 is about to be exhausted, the alarm circuit 1210 can remind the user to connect a power module (such as a mobile power bank) to continue charging the energy storage module 125, so as to ensure the normal use of the toilet seat heating function in the case of a power outage.

[0068] In some embodiments, referring to Figure 7 , Figure 7 is the sixth block diagram of the power supply control circuit provided by an embodiment of the present application. As shown by Figure 7 , in addition to an AC-DC power module 121, an optocoupler module 122, a first switch 123, a microcontroller 124, an energy storage module 125, a power module 126, a charging circuit 127, an overcurrent and overvoltage protection module 128, a current detection circuit 129, and an alarm circuit 1210, the power supply control circuit further includes a second switch 1211. Among them, the first end of the second switch 1211 is connected to the second end of the first switch 123, the first end of the second switch 1211 is further connected to the first end of the energy storage module 125, the second end of the second switch 1211 is connected to the power input end of the heating wire 11, and the third end of the second switch 1211 is connected to the third end of the microcontroller 124. Thus, when the mains power 10 supplies power to the heating wire 11, the microcontroller 124 can control the on / off of the second switch 1211 to control the energization or non-energization of the heating wire 11, thereby controlling the heating of the toilet seat. Among them, if the heating wire 11 is controlled to be energized, the heating wire heats the toilet seat; if the heating wire 11 is controlled to be non-energized, the heating wire does not heat the toilet seat. When the energy storage module 125 supplies power to the heating wire 11, the microcontroller 124 can control the on / off of the second switch 1211 to control the energization or non-energization of the heating wire 11, thereby controlling the heating of the toilet seat. When the power module 126 supplies power to the heating wire 11, the microcontroller 124 can control the on / off of the second switch 1211 to control the energization or non-energization of the heating wire 11, thereby controlling the heating of the toilet seat.

[0069] In some embodiments, referring to Figure 8 , Figure 8It is the seventh block diagram of the power supply control circuit provided by an embodiment of the present application. From Figure 8 As shown, in addition to the AC-DC power module 121, optocoupler module 122, first switch 123, microcontroller 124, energy storage module 125, power module 126, charging circuit 127, overcurrent and overvoltage protection module 128, current detection circuit 129, alarm circuit 1210, and second switch 1211, the power supply control circuit further includes a third switch 1212 and a main system control board 1213. Among them, the first end of the third switch 1212 is connected between the second end of the AC-DC power module 121 and the first end of the first switch 123, the second end of the third switch 1212 is connected to the main system control board 1213, and the third end of the third switch 1212 is connected to the fourth end of the microcontroller 124. The main system control board 1213 includes main functions such as controlling the water heating, drying heating, and spray gun movement of the intelligent toilet. During a power outage of the commercial power, it needs to be disconnected from the power supply to reduce the power consumption. Specifically, if the microcontroller 124 receives the electrical signal generated by the optocoupler module 122, it sends a fourth control signal to the third switch 1212 to control the third switch 1212 to close, so that the commercial power supplies power to the main system control board 1213. If the microcontroller 124 does not receive the electrical signal generated by the optocoupler module 122, it sends a fifth control signal to the third switch 1212 to control the third switch 1212 to open, so as to disconnect the power supply of the main system control board 1213. Thus, the power consumption can be reduced in the case of a power outage of the commercial power, and the heating function of the toilet seat can be ensured to be normal in the case of a power outage to the greatest extent. Refer to Figure 9 , Figure 9 is provided by an embodiment of the present application Figure 8 The circuit schematic diagram of the corresponding power supply control circuit.

[0070] In some embodiments, refer to Figure 10 , Figure 10 is the structural schematic diagram of the toilet seat provided by an embodiment of the present application. Refer to Figure 10, a temperature sensor 13 is provided inside the toilet seat ring. The temperature sensor 13 is used to detect the temperature of the toilet seat ring. The temperature sensor 13 is electrically connected to the microcontroller 124 to transmit a temperature detection signal to the microcontroller 124. The microcontroller 124 can control the on / off of the second switch 1211 according to the temperature detection signal to control the heating wire 11 to be energized or de-energized, thereby controlling the heating of the toilet seat ring. Specifically, the microcontroller 124 determines the temperature of the toilet seat ring based on the temperature detection signal. When the temperature of the toilet seat ring reaches the preset temperature, the microcontroller 124 can control the second switch 1211 to disconnect to control the heating wire 11 not to be energized, and the toilet seat ring does not continue to heat; when the temperature of the toilet seat ring is lower than the preset temperature, the microcontroller 124 can control the second switch 1211 to close to control the heating wire 11 to be energized to heat the toilet seat ring. Thus, the temperature of the toilet seat ring can be controlled to be maintained within the preset temperature range.

[0071] Referring to Figure 10 , a human sitting detection module 14 is also provided inside the toilet seat ring. The human sitting detection module is used to detect whether there is a human sitting on the seat ring. The human sitting detection module 14 is electrically connected to the microcontroller 124 to transmit a human sitting detection signal to the microcontroller 124. The microcontroller 124 can control the on / off of the second switch 1211 according to the human sitting detection signal to control the heating wire 11 to be energized or de-energized, thereby controlling the heating of the toilet seat ring. Specifically, the microcontroller 124 determines whether there is a human sitting on the toilet seat ring based on the human sitting detection signal. When there is no human sitting on the toilet seat ring, the microcontroller 124 can control the second switch 1211 to disconnect to control the heating wire 11 not to be energized, and the toilet seat ring does not continue to heat; when there is a human sitting on the toilet seat ring, the microcontroller 124 can control the second switch 1211 to close to control the heating wire 11 to be energized to heat the toilet seat ring. Thus, the heating function of the toilet seat ring can be controlled to be executed only when it is in use, and the heating function is not executed when the toilet seat ring is not in use, which can effectively reduce power consumption.
