Background technology:

2. With the continuous progress of electronic switching technology, intelligent control based on electronic switching technology is becoming more and more popular in smart home devices exposed to daily work and life.
3. The traditional electronic switch intercepts the power at certain periods of time on the power supply sine wave from the power supply firewire cable, and the resulting current will flow through the load, which will also make the voltage or current through the load no longer continuous and sudden change, resulting in the load light "flashing" or the equipment has abnormal noise, which greatly affects the user experience.


Technical implementation elements:

4. Based on this, it is necessary to provide an electronic switching circuit and smart home system for the above technical problems.
5. An electronic switching circuit comprises:
6. Energy storage module;
7. The charging module, connected with the energy storage module, is used to receive the charging signal provided by the external device, and after adjusting the charging signal, the charging voltage applicable to the energy storage module is output to enable the energy storage module to store electric energy;
8. The power supply regulating module is connected with the energy storage module to receive the power supply voltage output by the energy storage module, and after processing the power supply voltage, output the power supply driving signal;
9. The control module is connected with the power supply regulating module to generate a switching control signal under the power supply driving signal so that the electronic switch in the electronic switching circuit can control the on-off state between the external power supply and the load according to the switching control signal.
10. In one of the embodiments, the charging module comprises:
11. The rectifier unit is used to output DC voltage after the charging signal is rectified;
12. The voltage regulating unit, connected with the rectifier unit, is used to convert the rectified DC voltage into the charging voltage suitable for charging the energy storage module.
13. In one embodiment, the external device includes a wireless charging device, and the charging module also includes:
14. The wireless receiving unit is connected with the rectifier unit for magnetic coupling connection with the wireless charging device, receiving the wireless electromagnetic signal of the wireless charging device, and converting the wireless electromagnetic signal into the charging signal.
