Abstract: The switching device for an air purifier contains a circuit board, a timing and switching module, a manual switch, a fan module, a positive and negative ion production module, and a negative ion production module. The timing and switching module is configured on the circuit board, and the fan module is electrically connected to the circuit board. The two ion production modules are electrically connected to the timing and switching module and the manual switch. Under an automatic mode, the two ion production modules are activated alternately whereas, under a manual mode, the positive and negative ion production module is activated alone, thereby achieving greater flexibility.
