[0033] A smart toilet is a type of sanitary ware that integrates various smart technology functions, aiming to provide users with a more convenient, comfortable, and hygienic experience. Typically, users can activate the drying function of a smart toilet to evaporate the moisture remaining on the skin, achieving a dry and clean effect.

[0034] In the related art, a low-speed fan is installed on the smart toilet to achieve the drying function. However, the drying efficiency of the low-speed fan is low and cannot meet the needs of users. In another implementation method of the related art, the drying function is achieved by installing a high-speed fan in the smart toilet. However, the DC power supply that drives the high-speed fan requires a larger installation space of the smart toilet and is more expensive.

[0035] Therefore, in the related art, there is a problem that the high-speed fan in the smart toilet that meets user needs requires a large installation space, which in turn leads to high costs.

[0036] The following is combined with Figures 1 to 6 , further elaborating on the embodiments of the present application, wherein the reference numerals of the various structures are in the attached Figures 1 to 6 There is a mention in it.

[0037] An embodiment of the present application provides an intelligent toilet drying device, including a power supply module 110, the power supply module 110 including a low-voltage power supply module and a high-voltage power supply module; a main control module 120, the power supply module 110 is electrically connected to the main control module 120, and the low-voltage power supply module is used to provide a control low voltage for the main control module 120; a high-speed fan drive circuit 130, the power supply module 110 is electrically connected to the high-speed fan drive circuit 130, and the high-voltage power supply module is used to provide a working high voltage for the high-speed fan drive circuit 130, and the high-speed fan drive circuit 130 is electrically connected to the high-speed fan 131; a non-isolated circuit 140, the non-isolated circuit 140 is electrically connected to the main control module 120 and the high-speed fan drive circuit 130, and the non-isolated circuit 140 is used to convert a first transmission electrical signal generated by the main control module 120 based on the control low voltage into a second transmission electrical signal, so that the high-speed fan drive circuit 130 drives the high-speed fan 131 into a working state based on the second transmission electrical signal.

[0038] Furthermore, if Figure 1 As shown, Figure 1 This is an optional functional module diagram of an intelligent toilet drying device provided by an embodiment of the present application, wherein the power supply module 110 is electrically connected to the high-speed fan drive circuit 130 and the main control module 120, and is used to provide different voltages for the high-speed fan drive circuit 130 and the main control module 120; the main control module 120 is electrically connected to the high-speed fan drive circuit 130 through the non-isolated circuit 140, and the high-speed fan drive circuit 130 is also electrically connected to the high-speed fan 131. The non-isolated circuit 140 converts the first transmission electrical signal indicating the start of the high-speed fan 131 into a second transmission electrical signal that can be recognized by the high-speed fan drive circuit 130, and controls the high-speed fan 131 to enter the working state based on the second transmission electrical signal.

[0039] Furthermore, the power supply module 110 includes multiple different power supply parts. In an embodiment of the present application, the power supply module 110 includes a low-voltage power supply module and a high-voltage power supply module (not shown in the figure). Typically, the high-voltage power supply module is connected to the industrial frequency alternating current (mains power) to provide working voltage for components in the intelligent toilet drying device, such as the high-speed fan 131, that need to enter a working state based on high voltage; and the low-voltage power supply module 110 can usually have a built-in working power supply, and the voltage provided by the working power supply is usually relatively low, which is used to provide working voltage for components in the intelligent toilet drying device, such as the main control chip, that need to enter a working state based on low voltage.

[0040] It should be noted here that high voltage and low voltage are relative. In the embodiment of the present application, the working voltage used in the main control module 120 is usually 5 volts (V), and the working voltage used in the high-speed fan drive circuit 130 is usually 311V. At this time, the 5V voltage used in the main control module 120 is called low voltage, and the 311V AC voltage used in the high-speed fan 131 is called high voltage.

[0041] Furthermore, the main control module 120 includes a main control chip (not shown in the figure), which is used to manage and control the various functional modules in the smart toilet. Specifically, the main control chip can be a microcontroller unit (MCU), an application-specific integrated circuit (ASIC), or a field-programmable logic device (FPGA). The choice of the main control chip can be set according to actual conditions and is not specifically limited in the present embodiment.

[0042] Furthermore, the operating voltage required by the main control chip is usually low. Therefore, the main control chip can enter the working state based on the control low voltage provided by the low-voltage power supply module 110, while the operating voltage required by the high-speed fan drive circuit 130 is higher. If the main control chip and the high-speed fan drive circuit 130 are directly connected, safety hazards such as circuit short circuit and electric shock are very likely to occur. Therefore, in the embodiment of the present application, a non-isolated circuit 140 is used to connect the main control chip and the high-speed fan drive circuit 130, while ensuring the safe operation of the main control chip and the high-speed fan drive circuit 130, saving the installation space of the smart toilet.

[0043] Furthermore, the high-speed fan 131 can be a three-phase high-voltage brushless DC motor, an axial flow fan or a centrifugal fan, etc., and the embodiment of the present application does not make any specific restrictions.

[0044] Furthermore, when the user wants to enable the drying function of the smart toilet, the main control chip can generate a first transmission electrical signal. Since the frequency, pulse width modulation, etc. of the working voltage required by the main control chip and the high-speed fan drive circuit 130 are different, the first transmission electrical signal is first transmitted to the non-isolated circuit 140, and the non-isolated circuit 140 converts the first transmission electrical signal into a second transmission electrical signal suitable for the high-speed drive circuit. Afterwards, the high-speed fan drive circuit 130 drives the high-speed fan 131 into working state based on the second transmission electrical signal.

[0045] It is understandable that in related technologies, electromagnetic isolators or relays and other devices are usually used to achieve electrical isolation between the high-voltage working area and the low-voltage control area. Under this implementation method, the installation space occupied by the smart toilet will be relatively large, and the costs incurred in terms of materials, production and transportation will also be higher. The non-isolated circuit 140 used in the embodiment of the present application occupies a small volume. While achieving the same function, it occupies a smaller installation space, thereby reducing costs.

[0046] The following will further explain the smart toilet drying device provided in the embodiment of the present application.

[0047] In some embodiments, the main control module 120 includes a main control chip, the main control chip includes a first control transmission pin, the non-isolated circuit 140 includes a first signal transmission pin, the first control transmission pin is electrically connected to the first signal transmission pin, and the first control transmission pin is used to transmit the first transmission electrical signal to the first signal transmission pin.

[0048] Furthermore, the first transmission electrical signal is a pulse width modulation signal (PWM), such as Figure 2 、 Figure 3 As shown, Figure 2 This is a schematic diagram of the pins of an optional main control chip of an intelligent toilet drying device provided in one embodiment of the present application. Figure 3 This is a schematic diagram of an optional non-isolated circuit 140 pin of an intelligent toilet drying device provided by an embodiment of the present application, wherein a pin 1 is provided on the terminal of the main control chip, and pin 1 is used for grounding. In addition, a first control transmission pin (pin 2) is also provided on the terminal of the main control chip, and a first signal transmission pin (S PWM pin) is provided in the non-isolated circuit 140. The main control chip and the non-isolated circuit 140 are connected through the first control transmission pin and the first signal transmission pin. When the first transmission electrical signal is generated in the main control chip, the first control transmission pin can transmit the first transmission electrical signal to the first signal transmission pin.

[0049] In some embodiments, the non-isolated circuit 140 also includes a first light-emitting diode 141 and a first photoelectric receiving tube 142, the first signal transmission pin is electrically connected to the first light-emitting diode 141, and the first light-emitting diode 141 is electrically connected to the first photoelectric receiving tube 142; the first light-emitting diode 141 is used to convert the first transmission electrical signal transmitted by the first signal transmission pin into a first optical signal, and transmit the first optical signal to the first photoelectric receiving tube 142, and the first photoelectric receiving tube 142 is used to convert the first optical signal into a second transmission electrical signal.

[0050] Furthermore, the first light emitting diode 141 may be a low-power diode (LED) or an infrared LED, etc., and the first photoreceiving tube 142 may be a photodiode, a phototransistor or a photodetector, etc., and the embodiment of the present application does not impose any specific restrictions.

[0051] It can be understood that the main control chip and the high-speed fan drive circuit 130 are not directly electrically connected, but based on the non-isolated circuit 140, the first transmission electrical signal in the low-voltage working area is converted into a second transmission electrical signal that can flow into the high-voltage working area, thereby improving the stability and safety of the circuit in the intelligent toilet drying device.

[0052] In some embodiments, the non-isolated circuit 140 also includes a drive transmission pin, which is electrically connected to the first photoelectric receiving tube 142. The drive transmission pin is also electrically connected to the high-speed fan drive circuit 130. The first photoelectric receiving tube 142 transmits the second transmission electrical signal to the high-speed fan drive circuit 130 through the drive transmission pin.

[0053] Furthermore, if Figure 3 As shown, the drive transmission pin (Q1 pin) in the non-isolated circuit 140 is electrically connected to the first photoelectric receiving tube 142, and the drive transmission pin is also electrically connected to the high-speed fan driving circuit 130. When the first photoelectric receiving tube 142 converts the first optical signal into a second transmission electrical signal, the second transmission electrical signal can be transmitted to the high-speed fan driving circuit 130 through the drive transmission pin.

[0054] Furthermore, based on the non-isolated circuit 140, the intelligent toilet drying device can prevent electromagnetic interference between the main control module 120 and the high-speed fan drive circuit 130 through electrical isolation, thereby further improving the stability and safety of the circuit in the intelligent toilet drying device. In addition, electrical isolation can separate the main control circuit and the high-speed fan drive circuit 130, while facilitating inspection and maintenance.

[0055] It should be noted that Figure 3PA1, PA2, PA3 and PA4 are other pins in the non-isolated circuit 140. These pins can be electrically connected to other electronic devices according to actual conditions, and the embodiments of the present application do not impose specific limitations.

[0056] In some embodiments, the non-isolated circuit 140 also includes a drive feedback pin, which is electrically connected to the high-speed fan drive circuit 130, and the drive feedback pin is also electrically connected to the second light-emitting diode 143; the drive feedback pin is used to transmit the first feedback electrical signal sent by the high-speed fan drive circuit 130 to the second light-emitting diode 143, and the second light-emitting diode 143 is used to convert the first feedback electrical signal into a second optical signal.

[0057] Furthermore, if Figure 4 As shown, Figure 4 This is another optional non-isolated circuit pin diagram of the intelligent toilet drying device provided by an embodiment of the present application. The non-isolated circuit 140 also includes a drive feedback pin (Q2 pin). The high-speed fan drive circuit 130 is electrically connected to the non-isolated circuit 140 through the drive feedback pin. When the high-speed fan drive circuit 130 transmits the first feedback electrical signal to the second light-emitting diode 143 through the drive transmission pin, the second light-emitting diode 143 can convert the first feedback electrical signal into a second optical signal.

[0058] Furthermore, the first feedback electrical signal is used to represent relevant operating parameters of the high-speed fan 131 when it enters the working state, or a corresponding fault signal when a fault occurs in the high-speed fan 131 .

[0059] It should be noted that the parameters of the high-speed fan 131 represented by the first feedback electrical signal can be set according to actual conditions, and the embodiment of the present application does not impose any specific limitations.

[0060] It should be noted that Figure 4 PA5, PA6, PA7 and PA8 are other pins in the non-isolated circuit 140. These pins can also be electrically connected to other electronic devices according to actual conditions, and the embodiment of the present application does not make specific limitations.

[0061] In some embodiments, the non-isolated circuit 140 also includes a second photoelectric receiving tube 144 and a second signal transmission pin. The second photoelectric receiving tube 144 is electrically connected to the second light-emitting diode 143 and the second signal transmission pin, and the second signal transmission pin is electrically connected to the main control chip; the second photoelectric receiving tube 144 is used to convert the second optical signal transmitted by the second light-emitting diode 143 into a second feedback electrical signal, and transmit the second feedback electrical signal to the main control chip through the second signal transmission pin.

[0062] Furthermore, if Figure 2 、 Figure 4 As shown, the non-isolated circuit 140 also includes a second photoelectric receiving tube 144 and a second signal transmission pin (SFG pin). The main control chip also includes a second control transmission pin (pin 3), which is connected to the second control transmission pin. After the second light-emitting diode 143 converts the first feedback electrical signal into a second optical signal, the second photoelectric receiving tube 144 can convert the second optical signal into a second feedback electrical signal recognizable by the main control chip and transmit it to the main control chip, so that the main control chip adjusts the operating state of the high-speed fan 131 based on the second feedback electrical signal. When the main control chip continues to generate another transmission electrical signal to control the operating state of the high-speed fan 131 based on the second feedback electrical signal, the specific implementation method of transmitting this transmission electrical signal to the high-speed fan drive circuit 130 is similar to the operating steps of the first transmission electrical signal described above and will not be repeated here.

[0063] In some embodiments, the main control chip is also electrically connected to the heating drive circuit 150, and the heating drive circuit 150 is electrically connected to the power supply module 110 and the heating element 160; the main control chip is used to send a third transmission electrical signal to the heating drive circuit 150, and when the heating drive circuit 150 receives the third transmission electrical signal, it controls the heating element 160 to enter a working state.

[0064] Furthermore, if Figure 5 As shown, Figure 5 This is another optional functional module diagram of the intelligent toilet drying device provided by an embodiment of the present application. The main control chip can also be electrically connected to the heating drive circuit 150, and the heating drive circuit 150 can control the connected heating element 160 to enter the working state or the sleep state.

[0065] Among them, the heating element 160 can be a heating wire, a heating tube, etc. It can be understood that the volume of the heating element 160 is usually small, which is convenient for installation in the smart toilet drying device.

[0066] Furthermore, the third transmission electrical signal can be associated with the first transmission electrical signal. When the main control chip generates the first transmission electrical signal, the third transmission electrical signal is generated at the same time. In this way, when the high-speed fan 131 enters the working state, the heating element 160 also enters the working state at the same time. Figure 6 As shown, the high-speed fan 131 blows the air from the air inlet to the heating element 160 at high speed to form hot air, and then the hot air is blown out from the air outlet.

[0067] In some embodiments, the main control chip is also electrically connected to the wind temperature detection sensor 170, and the wind temperature detection sensor 170 is electrically connected to the heating element 160. The wind temperature detection sensor 170 is used to send an overload signal to the main control chip so that the main control chip controls the heating element 160 to enter a sleep state based on the overload signal.

[0068] Furthermore, if Figure 5 As shown, the main control chip is also electrically connected to the wind temperature detection sensor 170, and the wind temperature detection sensor 170 is electrically connected to the heating element 160, wherein the wind temperature detection sensor 170 can be a thermistor, a thermocouple or a temperature sensor, etc., and a temperature threshold can be preset in the wind temperature detection sensor 170. When the temperature of the heating element 160 exceeds the temperature threshold, the wind temperature detection sensor 170 can send an overload signal to the main control chip. In this way, the main control chip can control the heating element 160 to enter a dormant state according to the overload signal, so as to avoid safety problems in the smart toilet drying device caused by excessive temperature of the heating element 160.

[0069] Furthermore, the wind temperature detection sensor 170 can also detect the temperature of the hot air blown out. Figure 6 As shown, Figure 6 This is an optional air flow diagram of an intelligent toilet drying device provided in an embodiment of the present application. The wind temperature detection sensor 170 can also be arranged between the heating element 160 and the air outlet to avoid the wind temperature detection sensor 170 directly contacting the heating element 160 and causing related safety problems due to excessive temperature. At the same time, it can ensure that the wind temperature felt by the user is within an appropriate range, thereby improving the user experience.

[0070] In some embodiments, the embodiments of the present application also provide a smart toilet, in which the above-mentioned smart toilet drying device can be arranged.

[0071] In some embodiments, the smart toilet further includes a remote control module, which is used to control the smart toilet drying device.

[0072] Furthermore, a remote application program may be deployed on the client, and the remote application program may control the intelligent toilet drying device to enter a working state or a dormant state through a remote control module.

[0073] 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.

[0074] 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. Technical personnel familiar with the art can also make various equivalent modifications or substitutions under the shared conditions that do not violate the spirit of the present application. These equivalent modifications or substitutions are all included in the scope defined by the claims of the present application.
