Description

Technical Field

[0002] Common power supply methods for smart bathroom appliances include battery power and hydroelectric power. Battery power involves embedding lithium batteries, dry cell batteries, or other components within the appliance to power its electronic components, enabling functions such as temperature display. Hydroelectric power involves embedding a miniature hydroelectric generator within the appliance as its power supply system to power its electronic components.

Detailed Implementation

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0032] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0033] Figure 1 This is a schematic diagram of a dual power supply manager based on hydropower generation provided by this utility model. This embodiment can be applied to provide temperature-controlled electrical energy for bathroom equipment at low cost. (See reference) Figure 1 The dual power supply manager specifically includes: a hydropower generation module 1, a battery module 2, and a processor 3. The power input terminal of the processor 3 is connected to the first power output terminal of the hydropower generation module 1 and the power replenishment terminal of the battery module 2. The second power output terminal of the hydropower generation module 1 is connected to the first power input terminal of the battery module 2. The processor 3 is also connected to a module 4 to be powered, providing power and control signals to the module to be powered.

[0034] The hydroelectric power supply module, in response to the water flow information of the bathroom equipment, generates power supply energy and evaluation energy, and provides power supply energy to the processor through the first power supply output terminal and evaluation energy to the battery module through the second power supply output terminal; the battery module is used to conduct the supplementary power supply circuit of the battery module when the evaluation energy received at the first power input terminal is less than the preset supplementary energy value, so as to provide supplementary energy to the processor through the supplementary energy terminal; the control unit of the processor, in response to the power information received at the processor's power input terminal, provides working power to the bathroom equipment's power supply module, where the power information is power supply energy, or power supply energy and supplementary energy.

[0035] The water flow information can be understood as the water flow rate of the bathroom fixtures. Different water flow rates result in different amounts of electrical energy provided by the hydroelectric power generation module. The lower the water flow, the lower the current or voltage output by the module, and the less electrical energy it provides. The supplied electrical energy can be understood as the energy generated by the hydroelectric power generation module and transmitted to the processor to power its operation. The evaluation energy can be understood as the reference signal output by the hydroelectric power generation module, used to assess whether the module can provide all the electrical energy required by the bathroom fixtures. The preset supplementary power value is used as a basis for measuring the power supply capacity of the hydroelectric power supply module. When the assessed power is less than the preset supplementary power value, it is considered that the hydroelectric power supply module cannot provide all the power required by the bathroom equipment. It is necessary to use the energy stored in the battery module to supplement the power supply that the hydroelectric power supply module can provide, so that the processor and other functional modules of the bathroom equipment can operate stably. Conversely, when the assessed power is not less than the preset supplementary power value, it is considered that the hydroelectric power supply module can provide all the power required by the bathroom equipment. That is, only the power supply that the hydroelectric power supply module can provide is needed for the processor and other functional modules of the bathroom equipment to operate stably.

[0036] Assuming the preset supplementary power value is 5V, under normal circumstances, when the water flow is small (e.g., water flow rate is 2-3L / min), the assessed power value is between 0.8-5V. When the water flow is large (e.g., water flow rate is greater than 3L / min), the assessed power value is greater than 5V. Based on the relative relationship between the assessed power value and the preset supplementary power value, it can be determined whether the supplementary power supply circuit of the battery module needs to be turned on, and whether it is necessary to provide supplementary power to the processor through the power supplement terminal.

[0037] Figure 2 This is a structural schematic diagram of a hydroelectric power generation module provided by this utility model. Figure 2 As can be seen from the diagram, the hydropower generation module includes: a hydroelectric generator 11, a rectifier bridge 12, a first capacitor C1, a first diode D1, a second diode D2, a linear regulator 13, a second capacitor C2, a first power output terminal 14, and a second power output terminal 15.

[0038] Specifically, in combination Figure 2The connection relationships of various components in the hydropower power supply module are described. It can be seen that the first end of the hydropower generator is connected to the first end of the rectifier bridge, the second end of the hydropower generator is connected to the second end of the rectifier bridge, the third end of the rectifier bridge is connected to the first end of the first capacitor, the second power supply output terminal, the first end of the first diode, and the third end of the linear regulator, respectively.

The port numbers of each component are not shown in the diagram.

[0040] Specifically, in combination Figure 3 The connection relationships of each component in the supplementary power supply circuit are explained.

[0041] For example, when "+DC" is between 0.8-5V, the second field-effect transistor Q2, the first field-effect transistor Q1 and the third diode D3 are turned on. The battery will transmit supplementary power to the processor's power input terminal through the first field-effect transistor Q1, the third diode D3 and the power supplement terminal 22. The supplementary power consumes the power stored in the battery 21.

[0042] Furthermore, the battery module also includes a charging unit; the charging unit is used to charge the battery using the supplied power when the supplied power is greater than a preset supply power value. The supply power exceeding the preset supply power value can be understood as a basis for ensuring sufficient power supply from the hydropower module. The purpose of this design is to store excess power in the battery, reducing the frequency of battery replacement and improving the utilization rate of new energy sources. Figure 4 This is a structural schematic diagram of a charging unit provided by this utility model.

Figure 4 In the figure, GND represents the ground signal, VCC1 represents the power output from the first power supply output terminal of the hydroelectric power supply module, the numbers around the battery charger 23 represent the port number of the battery charger 23, and the port numbers of the other components are not shown in the figure.

[0043] Specifically, in combination Figure 4 It can be seen that the first terminal of the battery charger is connected to the ground signal, the second terminal of the battery charger is connected to the positive terminal of the battery, the third terminal of the battery charger is connected to the first power supply output terminal, and the fourth terminal of the battery charger is connected to the ground signal through the fifth resistor.

The temperature detection unit is used to acquire water temperature data of the bathroom equipment and transmit the water temperature data to the processor. The water temperature data is used to assist the processor in generating temperature display control instructions, which instruct the display unit to display the temperature information of the bathroom equipment. The at least one display unit, in response to the temperature display control instructions sent by the processor, displays the temperature information corresponding to the temperature display control instructions.

[0045] Figure 5 This is a schematic diagram of a processor provided by this utility model, mainly showing the pins in the processor used to connect to the display unit. Figure 5 As can be seen, processor 3 includes 5 ports for connecting to the display unit, which are respectively connected to the wires represented by LED1, LED2, LED3, LED4 and LED5.

[0046] Specifically, the display unit includes four light-emitting diodes. Figure 6 This is a schematic diagram of the structure of a display unit provided by this utility model. Figure 6It includes four display units. Assume that LEDs A1, A2, A3, and A4 constitute the first display unit; LEDs B1, B2, B3, and B4 constitute the second display unit; LEDs C1, C2, C3, and C4 constitute the third display unit; and LEDs D1, D2, D3, and D4 constitute the fourth display unit.

This solution addresses the issues of battery-powered bathroom fixtures where the power supply time depends on the performance of the built-in battery, requiring frequent battery replacements during periods of high water usage, and resulting in poor intelligence and user experience. It also resolves the problem of bathroom fixtures with built-in hydroelectric generators experiencing insufficient power and current when water flow is low, leading to reduced electrical energy output, low brightness and flickering temperature indicators, and even malfunctions of some functional modules, thus affecting the usability of the bathroom fixtures.
