Detailed Implementation

[0021] Example 1

[0022] like Figure 1-4 As shown, this embodiment provides a 220V push-button and sensor dual-purpose switch. Compared to existing Mijia smart switches on the market, such as the Mijia switch with model number DHKG01ZM, which are single-pole, single-control switches with fixed structures, making internal maintenance and panel installation inconvenient, and lacking dual push-button and sensor functions, this application uses an infrared panel and base snap-fit ​​structure, facilitating switch maintenance. This application also features both mechanical push-button and infrared sensor functions, increasing flexibility in use.

[0023] This application differs from existing smart switches in that it includes an infrared-transmitting panel 1 and a base 2. The infrared panel is mounted on the surface of the base. The base 2 has a latching part 21 with a slot 22, and the infrared-transmitting panel 1 has a hook 11 that engages with the latching part 21. This facilitates hooking and mounting, and makes it easy to disassemble and maintain the circuit board inside the base. The base 2 has a circuit board 3, which can be installed inside the base by screwing or embedding. Since screwing or embedding are commonly used installation methods, they will not be described in detail here. The bottom surface of the circuit board 2 has terminals, including a 220V neutral terminal 21 and a 220V live terminal 32. The 220V neutral terminal 31 and the 220V live terminal 32 are each equipped with a fixing screw 33 to secure the power cord. The base 2 has two symmetrically arranged fixing screw holes, which are used to fix the base 1 to a vertical surface, such as a wall, using fixing bolts 23.

[0024] The circuit board 3 includes an infrared receiving module 35 with an infrared receiving probe 34, an infrared transmitting module 37 with an infrared transmitting probe 36, a micro switch 38, a wireless transmission module 39, a processor module 40, a relay 41, and a power supply module 42. The processor module is model AT89S52-24PU, the power supply module is model AM11-5W05C [5V / 1000mA], the infrared receiving module is model VS1838B, the Bluetooth / WIFI module is model HC-04, the relay is model CDZ9-52PL, the infrared transmitting module is a 3528 surface-mount infrared emitting tube, and the micro switch is model 2*12*4.3. The power supply module 42 has a VCC terminal and a GND terminal, and the processor module 40 has a VCC terminal, a GND terminal, a P0 terminal, a P2 terminal, a P3 terminal, a P4 terminal, and a P5 terminal. The infrared receiving module includes a first infrared receiving module 35 and a second infrared receiving module 351. The infrared transmitting probe and the infrared receiving probe are respectively located on the top surface of the circuit board 3. Infrared emitting probes are integrated on an infrared emitting module. Infrared receiving probes are integrated on first and second infrared receiving modules, respectively. Each infrared emitting module has one or more infrared emitting probes. The first and second infrared receiving modules and the infrared emitting module are located on the same side of the top surface of circuit board 3. The micro switch 38 and the infrared receiving module with an infrared receiving tube are located on the same side of circuit board 3. The wireless transmission module uses either a Bluetooth or Wi-Fi transmission module. The first and second infrared receiving modules and the infrared emitting module each have a VCC terminal and a GND terminal.

[0025] In the electrical connection, the power module 42 is connected to 220V AC power. The power module 42 is electrically connected to the relay 41, and the relay 41 is also electrically connected to the P4 terminal of the processor module 40. One pin on the control side of the relay 41 is electrically connected to the processor module 40. The two ends of the controlled end of the relay 41 are respectively connected to the 220V live wire and neutral wire. Alternatively, one neutral wire and one live wire, or a single live wire with a broken end. The power module also has VCC and GND terminals, which provide 3-36V DC power for the circuit board. The power module 42 also has VCC and GND terminals that are electrically connected to the VCC and GND terminals of the processor module 40, respectively. The P0 and P1 terminals of the processor module 40 are electrically connected to the first and second infrared receiving modules, the P2 and P3 terminals of the processor module 40, and the wireless transmission module, respectively. The micro switch 38 is electrically connected to the P5 terminal of the processor module 40. The micro switch 38 is also electrically connected to the VCC terminal of the power module 42 and the VCC terminal of the processor module 40. The infrared emitting probe of the infrared emitting module is connected to the VCC terminal wiring and the GND wiring, respectively.

[0026] The working principle of the above structure is as follows: the base of this application is fixed to the corresponding position on the wall by fixing bolts, and the infrared panel is assembled to form the switch structure of this application by the cooperation of the hook and the buckle.

[0027] When the user presses the infrared panel, the infrared panel contacts the microswitch. The processor module's data pin P5 is at a high potential, and the processor module determines that the switch has been pressed. The processor module then sets its data pin P4 to a low level, activating the relay. The relay's controlled end then engages or disengages, achieving control.

[0028] When a hand slides across the sensing area, both the infrared probe and the infrared receiver module detect infrared light. This triggers voltage changes on terminals P0 and P1 of the processor module. The direction of the hand's movement can be determined based on the timing of the detection. If triggering the first infrared receiver module first, followed by the second, is set to "on," then triggering the second infrared receiver module first, followed by the first, is set to "off." Based on this principle, the processor module sets the control terminal of the relay, specifically the voltage on terminal P4, to control the opening and closing of the relay.

[0029] This switch is equipped with a wireless transmission module, which allows it to connect to devices such as Xiaomi gateways. It transmits the switch status to remote devices, enabling different device states to be controlled by forward and reverse hand gestures.

[0030] It should be noted that the above preferred embodiments are merely illustrative of the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
