A smart tap into which one or more power plugs can be inserted, the smart tap being characterized by being provided with a voltage waveform measuring means, a current waveform measuring means, a communication means, a control means, and an arithmetic unit, the voltage waveform measuring means and current waveform measuring means being means for measuring a voltage waveform and a current waveform of electricity supplied to each of one or more household electric appliances that are connected via the respective power plugs, the communication means being a means for transmitting the voltage waveform and the current waveform or results of processing the waveforms to a server that is installed at a different location than the smart tap and receiving control signals based on computation results of the server, and the control means being a means for performing on / off control of the electricity supplied to the household electric appliances and regulating the amounts of electricity to be supplied on the basis of the control signals. When powering multiple electric appliances, the smart tap identifies the household electric appliances that are connected with power plugs according to the measurement results of the electricity waveforms of the respective electric devices. Furthermore, the smart tap measures / computes the amounts of electricity required by the household electric appliances, and ascertains the operating status of each electric appliance and detects for abnormal operations to control an EoD system.

The invention relates to a dust removing method of a spring tube dust remover. The spring tube dust remover comprises a dust removing cavity, a purifying cavity and a dust hopper, wherein the purifying cavity and the dust removing cavity are separated by a separating plate; dust removing units are rotationally and symmetrically arranged on the lower surface of the separating plate; each dust removing unit comprises a fixing shaft and an electromagnetic loop; the electromagnetic loops can do reciprocating sliding along the axes of the fixing shafts; the electromagnetic loops are electrically connected with a dust removing power supply; dust removing tubes are fixedly arranged under the electromagnetic loops; the dust removing tubes and the fixing shafts are coaxially arranged; the lower ends of the dust removing tubes are fixedly arranged on conducting strips arranged at the lower part of the dust removing cavity in a sealing way; the conducting strips are electrically connected with the dust removing power supply; each dust removing tube comprises an electromagnetic spring and a dust removing net; the upper ends of the electromagnetic springs are electrically connected with the electromagnetic loops; the lower ends of the electromagnetic springs are electrically connected with the conducting strips; the electromagnetic springs are fixedly sheathed in the dust removing nets. The spring tube dust remover is novel and unique in structure and is capable of efficiently cleaning dust and effectively increasing the cleaning efficiency.
