[0002] Smart toilet seats typically come equipped with multiple functions such as heated seat, warm water washing, and warm air drying, greatly enhancing the user experience. To achieve these functions, smart toilet seats consume a certain amount of electricity when operating. Their overall heating power design is usually based on meeting the basic needs of users in most regions, without any special restrictions for specific power conditions.

[0003] However, the distribution of electricity resources is uneven globally. Some countries and regions face insufficient electricity supply due to geographical, economic, or policy reasons. To address this challenge, these regions often implement measures to limit daily household electricity consumption to ensure the rational allocation and sustainable use of electricity resources. Against this backdrop, the widespread use of high-energy-consuming appliances such as smart toilet seats, especially without power management measures, could lead to households reaching their daily electricity limits prematurely, thus restricting the normal use of other essential appliances and causing inconvenience to users. Therefore, developing a smart toilet seat that can adapt to areas with limited electricity supply is particularly important. Utility Model Content

[0028] Figure 1 This is a module block diagram of a low-power output smart cover provided in an embodiment of the present utility model;

[0029] Figure 2 This is another module block diagram of a low-power output smart cover provided in this embodiment of the utility model. Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] See Figure 1 A low-power output smart cover includes a power module, a main control module, a switch module, a load function module, and an interaction module. The power module is connected to an external power source and outputs power, such as AC mains, which it steps down and regulates to output the required 24V, 12V, 5V, and 3.3V supply voltages for each module. The power module is connected to both the main control module and the load function module, supplying power to both. When current flows through the positive terminal of the power module, through the load function module, and back to the negative terminal of the power module, a complete circuit is formed, and the load function module is powered.

[0032] The switch module is connected to the main control module and is turned on or off according to the control signal from the main control module. Simultaneously, the load function module is connected to both the power supply module and the switch module, controlling the power supply circuit from the power supply module to the load function module by turning the switch module on or off. In this embodiment, the combined output power of the load function module and the power supply module is less than 500W, meaning the overall output power of the smart cover is less than 500W, thereby alleviating household electricity consumption in areas with power rationing.

[0033] The interaction module is connected to the main control module. Users initiate the operation of the load function module and / or switch its operating mode through the interaction module. Specifically, the interaction module selects a working mode and transmits this mode signal to the main control module. The main control module then adjusts the control signal to the switch module accordingly, thereby controlling the load function module to switch to the desired operating mode. The interaction module includes a control terminal, which may include at least one of the following: buttons on the cover, a mobile phone, a remote control, or a tablet. Mode signals can be sent directly to the main control module via the buttons on the cover, or via a mobile phone, remote control, or tablet, or wirelessly.

[0034] In this embodiment, when low-power operation is required, the low-power mode is selected via the interaction module. The main control module sends a control signal to the switching module to reduce the on-time to off-time ratio of the switching module, i.e., to increase the duty cycle of the control signal, thereby reducing the power of the load function module and thus making the overall power less than 500W. It should be noted that the main control module's adjustment of the PWM duty cycle based on instructions from the terminal (interaction module) is a mature existing technology in the field of automatic control, and this adjustment process does not involve any improvement to the computer program.

[0035] This utility model's low-power output smart cover, when used in areas with power restrictions, activates the interactive module, and the main control module controls the switch module to open the load function module. The sum of the power output of the power module and the output of the load function module is less than 500W, meaning the total power of the device is less than 500W, thereby reducing household electricity consumption.

[0036] Continue reading Figure 1 The load function module includes several load function components, such as a water temperature control module, an air temperature control module, and a seat temperature control module. The switch module includes several sets of switch components. Each load function component is connected to a corresponding switch component; each load function component is connected to the power supply module, and each switch component is connected to the main control module.

[0037] See Figure 2 In one embodiment, the switching assembly includes an optocoupler. The emitter of the optocoupler is connected to the main control module, and the receiver of the optocoupler is connected to the load function module. The main control module controls the on / off state of the emitter via PWM regulation, thereby controlling the on / off state of the power supply circuit of the load function module. Using an optocoupler as a switch has the advantages of electrical isolation, strong anti-interference capability, and precise switch control.

[0038] In another embodiment, the switching assembly includes an optocoupler and a silicon controlled rectifier (SCR). The emitter of the optocoupler is connected to the main control module, and the receiver of the optocoupler is connected to the control electrode of the SCR. The anode of the SCR is connected to the load function module, and the cathode of the SCR is connected to the negative terminal of the power supply module. The main control module controls the illumination of the emitter via PWM regulation, thereby controlling the conduction or cutoff of the SCR, and consequently controlling the on / off state of the power supply circuit of the load function module.

[0039] In other embodiments, the sum of the rated power of the load function module and the output power of the power supply module is less than 500W. Therefore, when the interaction module activates the load function module, the control module controls the switch module to conduct, and the load function module begins operation, resulting in an overall power consumption of less than 500W for the smart cover. The load function components employ low-power devices, ensuring that the sum of the output power of the load function module and the output power of the power supply module in low-power mode is less than 500W. The load function components include a water temperature control module, a seat temperature control module, and a fan temperature control module. The water temperature control module uses a water heating element with a rated power of less than or equal to 350W, the seat temperature control module uses a seat heating wire with a rated power of less than or equal to 50W, and the fan temperature control module uses a mica heating wire with a rated power of less than or equal to 200W. The water temperature control module and the fan temperature control module do not start operating simultaneously.

[0040] For example, the water temperature control module has a rated power of 350W, the fan temperature control module has a rated power of 200W, the seat temperature control module has a rated power of 50W, and other functional power (power supplied by the power module) is 70W. When the interaction module selects to start the load function module, the main control module controls the switch module to turn on, thereby enabling the power module to supply power to the load function module, and the load function module starts working. For example, when the low power mode is activated, the switch module controls all load function modules not to be activated simultaneously, that is, only some load function modules are activated, so that the sum of the output power of the activated load function modules and the power module is less than 500W. In this embodiment, the switch module controls the water temperature control module and the fan temperature control module not to start working at the same time. When the seat heating function and the water temperature heating function are activated, the fan temperature heating function is stopped, and the total output power = water temperature 350W + seat temperature 50W + power supply 70W = 470W, which is less than 500W. When the air heating and seat heating functions are turned on, the water heating function is stopped. The total output power of the machine = air temperature 200W + seat temperature 50W + power supply 70W = 320W, which is less than 500W.

[0041] In this embodiment, the load function module has a normal power mode and a low power mode. After the interaction module switches its operating mode, the main control module controls the load function module to switch to the low power mode. In the low power mode, the sum of the output power of the load function module and the output power of the power supply module is less than 500W. The main control module controls the switching module's on / off state via PWM regulation. The main control module can control the specific PWM duty cycle output of each load function component, thereby controlling the load function module to switch to the low power mode. The load function components and switching components are connected one-to-one, allowing for individual control of each load function component and thus enabling more low power modes.

[0042] For example: Assume the rated power of the water temperature control module is 1600W in an area with no power restrictions, the rated power of the fan temperature control module is 200W, the rated power of the seat temperature control module is 50W, and the power of other functions (power supply module) is 70W. When the low power mode is activated, the total power of the unit must not exceed 500W. This can be achieved by controlling the specific PWM duty cycle output of the water temperature control module, fan temperature control module, and seat temperature control module through the main control module, thereby limiting the power output of the entire unit. The total power is P1 = P water temperature + P fan temperature + P seat temperature + P other functions = 1600 * 20% + 200W * 20% + 50W * 20% + 70W = 440W, thus ensuring that the total power P1 does not exceed 500W.

[0043] Alternatively, the water temperature can be set to not be heated when the washing cycle is started; the air temperature can be set to not be heated when the drying cycle is started; and the seat temperature can be adjusted according to customer needs, thus ensuring that the total power of the machine does not exceed 500W. The maximum power of the machine is P2 = P water temperature + P air temperature + P seat temperature + P other functions of the machine = 0W + 0W + 50W + 70W = 120W, thus ensuring that the total power of the machine does not exceed 500W.

[0044] Alternatively, when the washing cycle is started, the water temperature is not heated; when the drying cycle is started, the air temperature can be adjusted according to customer needs (PWM control); the seat temperature can also be adjusted according to customer needs, thus ensuring that the total power of the machine does not exceed 500W. The maximum power of the machine is P2 = P water temperature + P air temperature + P seat temperature + P other functions of the machine = 0W + 200W + 50W + 70W = 320W; or, when the washing cycle is started, the water temperature is heated; when the drying cycle is started, the air temperature is not heated, the water temperature can be adjusted according to customer needs (PWM control); the seat temperature can also be adjusted according to customer needs, thus ensuring that the total power of the machine does not exceed 500W. The maximum power of the machine is P3 = P water temperature + P air temperature + P seat temperature + P other functions of the machine = 350W + 0W + 50W + 70W = 470W. The switching components are connected one-to-one with the load function components. By adjusting the PWM of each load function component individually through each switching component, the above-mentioned modes and many more modes can be realized, which will not be listed here.

[0045] This embodiment also provides a smart toilet, including the aforementioned low-power output smart seat, so that the smart toilet can be used in areas with power restrictions.

[0046] The foregoing description illustrates and describes preferred embodiments of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the present invention through the foregoing teachings or related technical or knowledge.
