Description

Technical Field

[0001] This utility model relates to the field of switch technology, and in particular to a single-button wireless switch. Background Technology

[0002] In recent years, with the rapid development of science and technology, the types of electrical equipment have become increasingly diverse, and intelligent applications have been widely adopted by users. These electrical devices cleverly combine traditional circuit breakers and panel switches, utilizing wired technology as well as various wireless technologies such as radio frequency input / output, Bluetooth, Wi-Fi, and infrared to achieve functions such as scene application switching, mode setting adjustment, and status condition customization through physical buttons or mobile applications. The realization of these functions has greatly improved the convenience and technological feel of users' lives, making daily life more intelligent and humanized.

[0003] However, it is worth noting that many traditional power switches still use a single-circuit design. This design only has a simple on or off state, and its functionality is relatively limited. It is difficult to meet the diverse needs of modern intelligent systems, let alone to organically integrate with intelligent electrical devices, thus limiting the overall efficiency of intelligent systems and the improvement of user experience. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a single-button wireless switch, which solves the technical problem that traditional power switches are usually single-wire circuits and difficult to integrate with smart electrical devices.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a single-button wireless circuit breaker for connecting to the current input terminal of an electrical device, including a housing as a mounting carrier, and the wireless circuit breaker further includes:

[0006] A communication module housed within the casing for wireless communication with external devices, and integrated with RF433.

[0007] The remote control is used for pairing and to control the switching status of the relay module;

[0008] Button SW2, located on the surface of the housing, controls the pairing status between the communication module and the RF433 remote controller, as well as the communication status between the communication module and external devices, and controls the switching status of the relay module via the communication module.

[0009] A relay module located inside the housing on the live wire, used to receive commands from the communication module and control the connection and disconnection of the line.

[0010] Preferably, the communication module includes a chip M2, and a button SW2 is connected to the 9th pin of the chip M2.

[0011] On the pin.

[0012] Preferably, the housing is provided with an indicator light D4, which is used to display the pairing status of the communication module and the RF433 remote controller, as well as the wireless communication status of the communication module and external devices. The indicator light D4 is located on pin 14 of the chip M2.

[0013] Preferably, the relay module includes a relay switch RY1, with pins 3 and 4 of the relay switch RY1 connected in series on the live wire to control the on / off state of the live wire. A diode D3 is connected between pins 1 and 2 of the relay switch RY1. A transistor Q1 is connected to pin 1 of the relay switch RY1. A resistor R2 is connected between pin 1 of the transistor Q1 and the communication module. A grounded capacitor C4 and a resistor R3 are connected in parallel between pins 1 and 2 of the transistor Q1.

[0014] Preferably, the current input terminal of the communication module is provided with a chip M1 for AC-DC conversion.

[0015] Preferably, the current input terminal of the indicator light D4 is connected to a power conversion module, which includes a chip U1. A 5V power supply is connected to pin 3 of the chip U1.

[0016] Pin 1 of chip U1 is grounded. A diode D2 is connected to pin 2 of chip U1. Pin 2 of chip U1 is connected to pin 4. A grounded capacitor C1 and a capacitor C2 are connected to pin 2 of chip U1.

[0017] By employing the above technical solution, this utility model provides a single-button wireless switch, which has at least the following beneficial effects:

[0018] 1. This utility model achieves an intelligent upgrade of traditional switches through the integrated architecture of communication module, single-button control, and relay module. Only one physical button SW2 is needed to simultaneously complete three core functions: control the pairing status of the communication module and RF433 remote control, manage the wireless connection between the communication module and external devices (such as APP), and directly control the on / off action of the relay module. This highly integrated design greatly simplifies the user operation process and solves the pain point that traditional single-circuit switches cannot be compatible with intelligent electrical equipment systems. Users can quickly switch device modes (such as self-locking / momentary / automatic) through buttons, or use wireless communication to realize advanced functions such as remote control and timed tasks, significantly improving the interconnectivity and scene adaptability of electrical equipment. At the same time, the modular structure reduces production complexity, making the product both cost-effective and easy to install (such as direct series connection to the power supply live wire), providing a lightweight solution for the transformation of old circuits.

[0019] 2. This utility model significantly improves the reliability and safety of device interaction through the multi-state visual feedback mechanism of indicator light D4. This indicator light is directly connected to pin 14 of the communication module chip M2 and displays two key states in real time: one is the pairing progress between the communication module and the RF433 remote controller (e.g., fast flash to enter pairing, slow flash to reset network configuration), and the other is the communication status between the device and external wireless devices (e.g., constant light to turn on, off to turn off). Users can intuitively judge the device's operating stage based on the light pattern (constant light / fast flash / slow flash / off) to avoid pairing failure or communication interruption due to misoperation. This instant feedback mechanism not only reduces the learning cost but also provides clear safety guidance in circuit operation (e.g., wiring test, mode switching) and reduces the risk of live operation.

[0020] 3. This utility model solves the electrical stability problem in on / off control through optimized circuit design of the relay module. The 3-4 pins of the relay switch RY1 are connected in series with the live wire to achieve physical on / off. Its driving circuit includes triple protection: transistor Q1 receives the communication module signal through resistor R2 to accurately control the on / off of the relay coil; capacitor C4 connected in parallel between the pins of Q1 and resistor R3 form a grounded RC circuit to absorb the voltage spike at the moment of switching; diode D3 connected across the relay coil suppresses back electromotive force and prevents reverse current from damaging the control chip. This design significantly improves the lifespan and anti-interference capability of the relay in frequent switching scenarios. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] To address the technical challenge of traditional power switches, which are typically single-circuit circuits and difficult to integrate with smart devices, this application provides a single-button wireless switch. This module is suitable for AC power supply control with multi-load outputs, featuring high-voltage isolation protection and low-voltage signal triggering. It can be used with any device requiring switching, such as in homes, hotels like Home Inn and Hanting, campground tents, serviced apartments, and vehicles. The wireless switch is connected to the current input circuit of the device. Figures 1-6 As shown, Figure 6 The dotted lines in the diagram indicate that the two wires do not intersect. Including the housing 1, which serves as the mounting carrier, the wireless switch also includes:

[0031] A communication module 2, housed within the casing 1, is used for wireless communication with external devices. Wireless communication methods can include one or more of Wi-Fi, Bluetooth, radio frequency, and infrared. It is paired with the RF433 remote control. Currently, there are two main methods for resetting and configuring the communication module 2: One method involves pressing and holding button SW2 for more than 6 seconds until indicator light D4 flashes slowly, then releasing it. This clears the pairing between the router and the RF433 remote control within the communication module 2 and enters network configuration mode. Network configuration and adding RF433 devices can then be done via the app. The indicator light turns off after configuration is complete. The other method is to... (The text abruptly ends here, likely due to an incomplete sentence or missing information.) Clicking the reset button on the P will reset the product and put it into network pairing mode. There are two main ways to pair the RF433 remote control with communication module 2. Method 1: Press and hold button SW2 for more than 3 seconds until indicator light D4 flashes rapidly, then release. This will enter RF pairing mode. Press the button SW2 on the RF433 remote control or wireless switch to pair. After pairing, indicator light D4 will turn off. Several remote control buttons can be paired. Method 2: You can view the currently paired RF433 codes on the APP, and delete or add them. Press the button number you want to add, then press the RF433 remote control button. The controller or communication module 2 can be paired by pressing button SW2. This method utilizes the existing functions of communication module 2. By pressing and holding button SW2 for different durations, different commands are issued. Communication module 2 can also control the switching state of relay module 3. The input terminals of this wireless circuit breaker are connected to the L and N lines of the power supply output, and the output terminals are connected to the L and N lines of the appliance to be controlled. Before wiring, the power must be turned off, and a test pen must be used to confirm that the L / N lines are not energized before wiring. Ensure electrical safety and insulation. It is best to have a fuse inside the product for the L line, which controls the on / off state of the L line; therefore, the L / N lines must not be reversed. To prevent issues such as residual power after fuse failure or shutdown (which can cause problems like residual light when a bulb is off), press button SW2 to test if the live wire can be turned on and off normally. Indicator D4 will be constantly lit when on and off when off. It is preset to turn on automatically after power is supplied. Button SW2, located on the surface of housing 1, controls the pairing status of communication module 2 and RF433 remote control, as well as the communication status between communication module 2 and external devices, and controls the switching status of relay module 3 through communication module 2. Relay module 3, located inside housing 1 on the live wire, receives commands from communication module 2 and controls the connection and disconnection of the line.

[0032] For the APP that can wirelessly communicate with communication module 2, various intelligent settings can be configured. For example, the product can be set to self-locking and momentary operation modes on the APP. In self-locking mode, pressing the RF433 switch or the switch on the APP once will cause the product to switch between output on and off. In momentary operation mode, pressing the RF433 switch or the switch on the APP once will cause the product to output on and then cut off after one second. The product can also be set to support actuated switch mode on the APP. An actuated switch is connected in series at the input of the electrical device. When pressed, the product is de-energized, and when released, the product is re-energized. After being energized, the product switches between output on and off. For example, if the product is currently in the output on state, the input is de-energized, and then energized again, the product output is off, and vice versa. Furthermore, the APP can perform product switch control, set delay switch control, set timer switch control, and set cyclic tasks. Therefore, various personalized settings can be achieved through the APP that wirelessly communicates with communication module 2, realizing an organic integration with smart electrical devices.

[0033] In order to realize the various functions of the communication module 2 mentioned above, the communication module 2 includes a chip M2, and the button SW2 is connected to pin 9 of the chip M2. One model of the chip M2 can be Ai-WB2-01M.

[0034] To facilitate users in knowing the pairing status of communication module 2 with the RF433 remote controller and to display the wireless communication status between communication module 2 and external devices, an indicator light D4 is provided on the housing 1. Indicator light D4 is used to display the pairing status of communication module 2 with the RF433 remote controller and the wireless communication status between communication module 2 and external devices. Indicator light D4 is located on pin 14 of chip M2, thereby realizing the status display function.

[0035] Relay module 3 is used to control the on / off state of electrical equipment according to the instructions of communication module 2. The following is a circuit structure for implementing this function. Relay module 3 includes relay switch RY1. Pins 3 and 4 of relay switch RY1 are connected in series on the live wire to control the on / off state of the live wire. A diode D3 is connected between pins 1 and 2 of relay switch RY1. A transistor Q1 is connected to pin 1 of relay switch RY1. A resistor R2 is connected between pin 1 of transistor Q1 and communication module 2. A grounded capacitor C4 and a resistor R3 are connected in parallel between pins 1 and 2 of transistor Q1.

[0036] The communication module 2 has a specific working environment. Therefore, based on its own characteristics, it is necessary to convert the AC in the line to DC before inputting it into the communication module 2. Therefore, a chip M1 for AC-DC conversion is provided at the current input terminal of the communication module 2.

[0037] Indicator D4 can only operate under a specific voltage, so the input voltage needs to be converted to a specific voltage. Therefore, a power conversion module is connected to the current input terminal of indicator D4. The power conversion module includes chip U1. A 5V power supply is connected to pin 3 of chip U1, pin 1 of chip U1 is grounded, diode D2 is connected to pin 2 of chip U1, pins 2 and 4 of chip U1 are connected, and grounded capacitors C1 and C2 are connected to pin 2 of chip U1.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
