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.

Abstract: The present invention discloses a power supply wire receiving structure comprising a cable take-up unit and a charging wire. The charging wire is applicable to an electronic device and made of bullet-proof material so as to have high tensile strength. The charging wire is flat-shaped so that it is easy to be received in the cable take-up unit. The combination of the charging wire and the cable take-up unit enables the charging wire to be received in the cable take-up unit and facilitates the arrangement of the wire. Furthermore, the cable take-up unit can be coupled to a charging unit which has an accommodating groove so that the cable take-up unit is received in the accommodating groove of charging unit to reduce the product volume and be easy to carry.
