AI Technical Summary
In the existing technology, the power control board and command receiving board of the range hood need to be connected separately during the manufacturing process, which leads to a longer production process and increased costs, and may also cause connection errors.
The power control function and user command receiving function are integrated on a single circuit board, including a switch-mode power supply, bidirectional thyristors and command receiving components, to achieve a compact and reliable structure that controls the operation of the range hood through a single circuit board.
It simplifies the manufacturing process, reduces production costs, and improves the reliability and durability of the control board, avoiding connection errors.
