[0034] As an emerging intelligent device, smart switches are demonstrating their unique advantages and potential in the hotel industry. Firstly, smart switches significantly enhance the customer experience by providing a convenient, comfortable, and personalized stay. Guests can easily adjust room lights, air conditioning, televisions, and other devices via a mobile app or voice control, eliminating the need for manual operation and greatly improving convenience. Furthermore, smart switches also feature timed on / off switching, power consumption statistics, and energy-saving modes, effectively reducing hotel energy consumption and operating costs. The timed on / off function allows hotels to automatically turn off unnecessary electrical appliances after guests leave their rooms, preventing energy waste. Simultaneously, the power consumption statistics function helps hotel managers monitor the power usage of each room in real time, enabling them to promptly identify and resolve potential energy waste issues.

[0035] The introduction of smart switches has also significantly improved hotel management efficiency. Hotel managers can remotely monitor and control electrical equipment in each room through a central control system, promptly identifying and addressing equipment malfunctions and anomalies. Smart switches and sockets can also seamlessly integrate with other intelligent hotel systems (such as room management systems and energy management systems) to achieve data sharing and interoperability, providing strong support for hotel decision-making.

[0036] Furthermore, the introduction of smart switches has brought more innovative service possibilities to hotels. For example, hotels can provide guests with personalized lighting schemes or music playlists based on their needs and preferences; or provide smart health reminders and consultation services based on guests' lifestyles and health conditions.

[0037] In summary, smart switches in hotels are becoming an important part of the hotel's intelligent transformation, leading a new trend in the future hotel industry, thanks to their advantages in providing a convenient customer experience, energy conservation and environmental protection, improved management efficiency, enhanced security, and promotion of innovative services.

[0038] However, smart switches are generally quite large, and when installed in 86-type junction boxes, the internal wiring space is limited, making future maintenance inconvenient. Furthermore, installing smart switches is more complex than installing traditional switches, requiring professional installation. Before installing a smart switch, the power must be disconnected, and the neutral and live wires must be accurately identified, which typically requires technical knowledge and experience. If the installation process is unfamiliar, it may be necessary to seek assistance from an electrician, increasing installation costs and time.

[0039] Currently, smart switches on the market are generally large in size.

[0040] System stability: For whole-house smart systems, the stability of smart switches is a potential issue. While smart switches offer convenience and comfort, instability may occur during use, potentially impacting user experience and satisfaction.

[0041] In summary, existing smart switches suffer from technical bottlenecks in practical use, including excessive size, complex installation, high cost, and wasted space. These issues limit the application of smart switches in situations with limited space or requiring flexible installation, failing to achieve a more efficient and convenient installation and maintenance method.

[0042] Next, through some specific embodiments and accompanying drawings, we will describe in detail how this application solves the technical bottlenecks of the above-mentioned smart switches in actual use, such as excessive size, complex installation, high cost, and wasted space.

[0043] like Figure 1 As shown, a wireless smart switch includes a switch body and an electronic circuit board disposed within the switch body.

[0044] The switch body includes a rear shell, a middle cover plate, and a front cover plate. The middle cover plate is located between the rear shell and the front cover plate, and the middle cover plate is detachably connected to the rear shell and the front cover plate respectively.

[0045] The electronic circuit board integrates a main control module, a switching power supply circuit, and a wireless transceiver module. The main control module is used to control the power supply and communication functions of the switching power supply circuit, and the wireless transceiver module is used for wireless communication.

[0046] It should be noted that the wireless smart switch body consists of a rear shell, a middle cover plate, and a front cover plate, which are connected in a detachable manner. The middle cover plate is located between the rear shell and the front cover plate. This structural design ensures that the switch body's casing not only has good stability and reliability but also facilitates assembly and disassembly, making it convenient for future maintenance and replacement.

[0047] The electronic circuit board integrates several important functional modules, including a main control module, a switching power supply circuit, and a wireless transceiver module. The main control module controls the power management and communication functions of the entire system; it can be a Zigbee module or a Bluetooth module, the choice depending on actual needs. The wireless transceiver module is responsible for wireless communication functions, supporting wireless connections and data transmission between devices, thereby enabling remote control and wireless configuration.

[0048] This electronic circuit board, through an optimized design, integrates multiple circuit boards required in traditional smart switches onto a single board, reducing the number of boards, saving space, and improving circuit reliability. Simultaneously, the integrated four-channel self-reset button circuit, four-channel indicator lights, and four-channel relay modules enable this smart switch to achieve powerful control functions and a flexible user experience while maintaining a compact size.

[0049] Compared with existing technologies, the wireless smart switch of this utility model achieves significant technical effects through the following technical means:

[0050] Reduced space occupation: By integrating multiple circuit function modules onto a single electronic circuit board, space is significantly saved. This not only reduces the size of the switch body (external dimensions: 86mm × 86mm × 28mm, embedded dimensions: 64mm × 59mm × 17mm) but also optimizes the wiring layout, facilitating installation and maintenance. Compared to traditional smart switches, which occupy more space and are more complex to install, this solution offers a more flexible installation method in space-constrained environments, resolving the installation and space utilization issues of traditional smart switches.

[0051] Simplified installation process: Due to the integrated design of the circuit board, the number of circuit boards required is reduced, which not only lowers manufacturing costs but also reduces the complexity of the installation process. Traditional smart switches require multiple circuit boards, and installation requires professional personnel to perform complex operations such as power disconnection and wiring. The design of this utility model simplifies the installation process, reduces the skill requirements for installers, and reduces installation time and costs.

[0052] Enhanced System Stability and Functional Integration: This wireless smart switch integrates a main control module, a switching power supply circuit, and a wireless transceiver module, ensuring stability while providing powerful wireless communication capabilities, supporting Bluetooth or Zigbee wireless protocols. This enables the device to achieve various intelligent control functions such as remote control, timed on / off switching, and status feedback, greatly improving the user experience. Through the application of the Bluetooth Mesh communication protocol, data transmission between the switch and other smart home devices is more secure and reliable, resolving potential issues caused by unstable wireless communication in existing smart switches.

[0053] Improved circuit reliability and resource conservation: By using a single circuit board and optimized power supply solutions (such as a non-isolated buck switching power supply constant voltage circuit), system reliability is improved, the number of components is reduced, and manufacturing costs are lowered. Compared to traditional smart switches that use multiple circuit boards, this design effectively reduces circuit board complexity and cost, providing consumers with a more cost-effective solution.

[0054] This utility model provides a wireless smart switch, including a switch body and an electronic circuit board disposed within the switch body. The switch body includes a rear shell, a middle cover plate, and a front cover plate, with the middle cover plate located between the rear shell and the front cover plate, and detachably connected to both the rear shell and the front cover plate. The electronic circuit board integrates a main control module, a switching power supply circuit, and a wireless transceiver module. The main control module controls the power supply and communication functions of the switching power supply circuit, and the wireless transceiver module is used for wireless communication. In this application, by integrating multiple functional modules onto a single electronic circuit board, the number of circuit boards required by traditional smart switches is significantly reduced, optimizing the space layout and effectively reducing the size of the switch body, making it more compact and easier to install and use. Compared to traditional smart switches, this solution effectively compresses the size of the switch body, thus better adapting to environments with limited space and solving the problems of excessive size and difficult installation of traditional smart switches. Simultaneously, the integrated design simplifies the installation process, reduces the operational complexity for installers, lowers the requirements for professional skills, shortens installation time, saves labor costs, and improves installation efficiency. In addition to size optimization, the electronic circuit board integrates key functions such as the main control module, switching power supply circuit, and wireless transceiver module. It supports Bluetooth or Zigbee wireless communication protocols, enabling intelligent functions such as remote control and timed switching, providing a richer user experience. Furthermore, through optimized power circuit design, this solution improves circuit stability and reliability, reduces the number of circuit components used, thereby lowering manufacturing costs and enhancing the overall product's cost-effectiveness.

[0055] In one embodiment of this application, the main control module is a Zigbee module or a Bluetooth module.

[0056] Zigbee modules are low-power, high-reliability wireless communication technologies suitable for smart homes, the Internet of Things (IoT), and other fields. Bluetooth modules, on the other hand, offer strong compatibility and widespread adoption, making them suitable for communication between various smart devices. The main control module communicates with remote devices via a wireless transceiver module, supporting functions such as remote control, timed switching, and status monitoring, thus enhancing the intelligence of the smart switch and the user experience.

[0057] Zigbee modules are primarily used in home automation control networks. They are characterized by low power consumption and low data rate, making them suitable for short-range, low-data-volume communication scenarios. Zigbee modules connect to other smart home devices through standard protocols, enabling the establishment of a stable and secure wireless network within the smart home system. Their reliability and security have been verified, providing users with long-term stable service.

[0058] Compared to Zigbee, Bluetooth modules have a wider range of applications and support interconnection with various devices. Bluetooth technology boasts advantages such as high speed and low latency, making it suitable for more scenarios, such as mobile device control and instant feedback. Bluetooth modules offer strong compatibility, enabling easy pairing with devices like smartphones and tablets, further enhancing the ease and smoothness of user operation.

[0059] In this embodiment, by employing a Zigbee or Bluetooth module, the wireless smart switch not only meets the wireless communication needs of different application scenarios but also provides richer and more stable communication functions, overcoming the shortcomings of traditional smart switches in terms of communication protocols and stability. Choosing a Zigbee module effectively reduces power consumption and extends battery life, making it particularly suitable for the long-term use of wireless sensors and smart home devices. A Bluetooth module, on the other hand, enhances the interconnectivity between devices, making it suitable for smart home environments requiring frequent operation and real-time feedback. Overall, this solution enables more flexible, convenient, and intelligent control through wireless communication, enhancing the product's competitiveness and market adaptability.

[0060] In one embodiment of this application, the electronic circuit board also integrates a four-channel self-reset button circuit, which is connected to the main control module.

[0061] It should be noted that the self-reset button automatically returns to its original state after being pressed, so there is no need to manually restore the button to its original state after operation. The four-channel self-reset button circuit design supports operation of four independent channels, each channel can control different functions or devices. For example, users can switch between single or multiple switch channels using the button, thereby controlling different electrical appliances.

[0062] The four-channel self-reset button circuit integrates multiple button functions onto a single circuit board, reducing the number of external buttons required in traditional smart switches and simplifying and integrating the switch design. In practical applications, the buttons not only function as physical buttons but can also remotely control corresponding electrical appliances or devices by sending signals via a wireless communication module, in conjunction with the control logic of the main control module. The status of each button is indicated by an indicator light, enhancing the user's understanding of the device's status.

[0063] In this embodiment, by integrating a four-channel self-reset button circuit onto the electronic circuit board, compared to the multiple independent buttons in traditional smart switches, this integrated design reduces the size of the switch body, improving the product's aesthetics and convenience. The self-reset button boasts high reliability and durability, avoiding the aging or damage issues of traditional buttons and enhancing the overall product's durability. Simultaneously, the four-channel design allows users to customize button functions as needed, improving the device's flexibility and operability. Overall, this solution enhances the user experience and market competitiveness of wireless smart switches by integrating a self-reset button and offering diverse button functions.

[0064] like Figure 1 As shown, in one embodiment of this application, the electronic circuit board also integrates a four-channel indicator light, which is connected to the main control module.

[0065] It should be noted that the four indicator lights are used to display the operating status of each switch channel, such as whether the switch is on, whether the operation is normal, or whether a fault has occurred. Each channel is equipped with an independent indicator light, which uses different colored LEDs to display different statuses. Typically, a green indicator light indicates that the device is in normal working condition, a red indicator light indicates that the device is faulty, and a yellow indicator light indicates that the device is in standby or abnormal state.

[0066] The indicator lights' operation is controlled by the main control module, which monitors the status of each channel in real time and provides feedback through the indicator lights. When a user operates the switch, the indicator lights update in real time, allowing the user to clearly understand the device's current status. The integrated design of the indicator lights simplifies the scattered indicating components found in traditional smart switches, reduces the circuit board area, and improves the overall compactness of the layout.

[0067] In this embodiment, by integrating four indicator lights, the working status feedback of the wireless smart switch is optimized, allowing users to clearly understand the operating status of each channel. Compared with traditional switch indicator lights, the integrated indicator lights in this solution improve the compactness of the device and the stability of the system by reducing space occupation and simplifying circuit design. At the same time, the four-channel design can display the working status of each channel in more detail, reducing user misunderstandings or inconveniences and improving the user experience. Overall, this design enhances the intelligence and efficiency of the wireless smart switch.

[0068] like Figure 1 As shown, in one embodiment of this application, the electronic circuit board also integrates a four-channel relay, which is connected to the main control module.

[0069] It should be noted that the function of a relay is to control the switching of circuits, allowing users to remotely or locally switch electrical appliances on and off. Each relay channel can independently control different loads, such as different lights, home appliances, or other smart devices. The relay control logic is executed by the main control module. The main control module sends control signals through a wireless communication module or physical buttons according to user instructions, and the relay performs the corresponding current switching operation after receiving the signal.

[0070] The integrated design of the relays enables the switch to control multiple electrical appliances or devices simultaneously and to interact with other smart devices. Compared to traditional smart switches that require multiple relays and circuit boards, this solution simplifies circuit design and improves system stability and response speed through the integration of four relays.

[0071] In this embodiment, the integrated four-channel relay design not only enables the wireless smart switch to control multiple devices simultaneously, improving functional scalability and flexibility, but also reduces the number of relays and circuit boards required in traditional smart switches, lowering costs and space requirements. Through intelligent scheduling by the main control module and precise control by the relays, this solution can efficiently achieve remote control of multiple devices, meeting various user needs in smart homes. Simultaneously, the relay integration enhances the switch's reliability and durability, reduces reliance on external components, and strengthens system stability and security.

[0072] In one embodiment of this application, the electronic circuit board also integrates a zero-crossing detection circuit, which is connected to the main control module.

[0073] It should be noted that the zero-crossing detection circuit is integrated on the electronic circuit board and is mainly used to detect the zero-crossing point of the AC current, that is, the zero-crossing point in the AC current cycle. The working principle of the zero-crossing detection circuit is to determine the direction of the current and the trend of voltage change by monitoring the zero-crossing point of the voltage waveform. The circuit can generate a trigger signal when the voltage is zero by sampling the voltage waveform, thereby helping the system to perform effective power control.

[0074] A zero-crossing detection module is installed at the front end of the switching power supply circuit. This module converts the AC waveform signal into a digital signal suitable for subsequent control system processing through filtering and sampling. After filtering, the voltage signal passes through a zero-crossing detection circuit to generate a high-precision timing signal used to control the opening and closing of relays or other electrical components. The zero-crossing detection circuit generally includes a rectifier circuit, a comparator, and a filter. All circuit components are connected via a PCB board to ensure accurate signal transmission.

[0075] With the integration of zero-crossing detection circuitry, the intelligent switching system can accurately identify the phase of the current, control the switching timing of electrical equipment, reduce arcing or surges generated during switching, and extend the service life of the equipment. This circuit can quickly respond to voltage fluctuations and perform timely switching control, ensuring the safety and stability of the equipment.

[0076] In this embodiment, the integration of the zero-crossing detection circuit enables the smart switch to precisely control the on / off timing of electrical appliances, solving the surge problem that may occur during the installation of smart switches mentioned in the background art. Traditional smart switches may damage electrical equipment due to the instantaneous current surge generated during switching, especially under heavy loads. The zero-crossing detection circuit, by switching at the zero-crossing point of the AC voltage, can effectively reduce the damage of surges to equipment, extend the service life of equipment, and improve system stability. In addition, zero-crossing detection technology can also avoid sparks when the load is turned off, reducing potential safety hazards and further improving the safety and reliability of the smart switch.

[0077] like Figure 2-9 As shown in one embodiment of this application, the switching power supply circuit is a non-isolated buck switching power supply constant voltage circuit, which includes an LP2178 non-isolated buck switching power supply constant voltage control driver chip.

[0078] It should be noted that the constant voltage circuit of the non-isolated buck switching power supply uses the LP2178 non-isolated buck switching power supply constant voltage control driver chip. The LP2178 chip is a high-efficiency buck power supply chip launched by Shenzhen Xinmao Microelectronics Co., Ltd., suitable for devices with a wide input voltage range (85VAC to 265VAC). This chip features high integration, high efficiency, and small size, enabling it to perform constant voltage power supply functions without using an isolated power supply. Specifically, the LP2178 chip integrates high-voltage power transistors, constant voltage control mode, peak current control, and overcurrent protection functions, which effectively ensure the stability and safety of the power supply system.

[0079] To meet the application requirements of smart switches, the buck power supply circuit adopts a Buck topology. This structure can regulate high input voltages (such as AC 220V) into a stable DC voltage to supply the internal circuitry. Furthermore, the circuit uses a combination of inductors and capacitors for filtering, ensuring a stable output voltage and preventing voltage fluctuations from affecting electrical equipment. The circuit also includes a temperature sensor and overcurrent protection to prevent system overload and protect circuit components from damage.

[0080] This non-isolated buck power supply circuit also features low power consumption and high conversion efficiency, effectively reducing size and cost compared to traditional isolated power supplies. The chip operates in a constant voltage control mode to ensure stable output voltage and meet the power requirements of other functional modules in the smart switch.

[0081] In this embodiment, by applying a non-isolated buck switching power supply constant voltage circuit, the intelligent switch of this invention significantly reduces the size and cost of the circuit while ensuring power supply stability. Compared to traditional isolated power supplies, non-isolated power supplies not only reduce one transformer and related isolation components but also reduce circuit complexity, shrink the overall size of the intelligent switch, and improve space utilization. Furthermore, the constant voltage control function provided by the LP2178 chip not only improves power supply efficiency but also avoids output voltage instability, ensuring the normal operation of each module of the intelligent switch. By optimizing power management, energy waste is reduced, further improving the overall performance and energy efficiency of the intelligent switch, thereby helping to reduce overall energy consumption and enhance user experience.

[0082] In one embodiment of this application, the wireless transceiver module includes a TLSR8258F512ET32 wireless transceiver chip.

[0083] It should be noted that the TLSR8258 chip is an ultra-low power, high-performance wireless transceiver chip that supports wireless communication protocols such as Bluetooth and Zigbee, meeting the needs of smart switches for efficient communication over short distances. This chip enables wireless interconnection between smart switches and other smart devices, supporting remote control of the switch status via smartphones or other control terminals.

[0084] The wireless transceiver module operates at a frequency of 2.4GHz, supports Bluetooth 4.0 and above, and supports the Zigbee protocol, enabling it to interconnect with other smart home devices and improve the overall intelligence level of the system.

[0085] In this embodiment, the integrated wireless transceiver module enables remote control and multi-device interconnection of the smart switch. The use of the TLSR8258F512ET32 chip not only improves the system's communication efficiency but also enhances its anti-interference capabilities, ensuring stable data transmission even in complex wireless environments. Through Bluetooth or Zigbee protocols, users can conveniently control the switch via smartphones, tablets, and other terminal devices, improving user convenience. Furthermore, the integration of this module allows the smart switch to support wireless networking, enabling it to work with other smart devices to form a complete smart home system, further enhancing the overall intelligence level of the smart home.

[0086] In one embodiment of this application, the outer dimensions of the switch body are 86mm×86mm×28mm; the embedded dimensions of the switch body are 64mm×59mm×17mm.

[0087] It should be noted that the switch body's external dimensions are 86mm × 86mm × 28mm, and its embedded dimensions are 64mm × 59mm × 17mm. This size design is adopted for the smart switch to address the problems of traditional smart switches being too large and inconvenient to install. Traditional smart switches are generally large, typically requiring 86mm × 86mm × 35mm of space. This leads to space constraints and wiring difficulties when installed in traditional 86-type junction boxes, posing a significant challenge to workers during installation, and the complex installation process requires professional personnel.

[0088] To overcome these problems, the intelligent switch of this invention adopts a more compact design. By designing the height of the switch body to 28mm instead of the traditional 35mm, the size of the switch is greatly reduced, making it easier to embed in a traditional 86-type junction box. At the same time, the internal circuit board of the switch adopts a single-board design, reducing the space occupied, providing more space for circuit layout, and simplifying the wiring process.

[0089] In this embodiment, by adopting an external dimension of 86mm×86mm×28mm and an embedded dimension of 64mm×59mm×17mm, the present invention successfully solves the problems of excessive space occupation and complex installation of traditional smart switches. The new smart switch does not require professional technicians during installation and can be installed in a smaller space, adapting to a wider range of building environments, especially suitable for locations with limited space. The smaller size also reduces manufacturing costs, effectively minimizing material waste and production costs. Furthermore, this design improves the convenience of installation and maintenance for users, making the smart switch easier to popularize and apply.

[0090] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
