Abstract:
A driver comprising a switched mode power supply, wherein said switched mode power supply comprises an existing coil, the driver circuit further comprises: a first power transmission antenna (42) formed as a first coil which is either the existing coil of the switched mode power supply or coupled to the existing coil of the switched mode power supply, said first power transmission antenna (42) is adapted for being magnetically coupled to a second power receiving antenna (44) thereby forming a wireless power transmitter.
Abstract:
This utility model provides an air cleaner (100, 200, 300), which comprises a housing (101, 201, 301); a first air inlet (102, 202, 302); a first air outlet (103, 203, 303); an air fan (104, 204, 304) configured to be located in an air channel formed between the first air inlet and the first air outlet; a washing chamber (105, 205, 305) configured to be at least partially located in the air channel; a distributing device for distributing liquid into the washing chamber; and a dry chamber (110, 210, 310) configured to be communicated with the first air outlet and at least partially located in the air channel. In such air cleaner, it is not necessary to utilize the filter members since the water is used for air cleaning and humidification simultaneously. Moreover, the purified and humid air can be discharged directly or dried through the dry chamber before being discharged as required, which avoids the overhigh humidity of the air and can dehumidify the indoor air.
