Yaozhu Company developed the world's first automatic gas stove shut-off device, which can be directly installed and used by users themselves without replacing the gas stove and without changing their usage habits; when a user forgets to turn off the fire, it immediately activates an alert and shuts off the stove fire. The patented adapter developed for various stove models worldwide allows this automatic fire shut-off knob to be installed on all stoves globally. In the four years since its launch, domestic sales have exceeded 150,000 units, shutting off the stove fire for users more than 500,000 times. Development of the IoT smart knob has been completed, and cooperation with major smart home manufacturers is underway; additionally, it has gained the favor of domestic telecommunications operators, and market launch planning is in progress. Cloud data on cooking fire usage is closely related to safety, health, and long-term care. In March 2023, the project passed the subsidy approval of the Industrial Development Bureau's "Value-Added Project for Stove Switch Systems in Home-Based Elderly Care," and the project is currently being executed. Affected by the pandemic, the expansion of overseas markets officially commenced this year, and sales agency collaborations have already been initiated in Singapore and Malaysia.
