Abstract: A message management method is performed at a computing device, the method including: storing received messages into a plurality of cache queues according to priorities of the received messages; extracting messages from the plurality of cache queues, and storing the extracted messages into a uniform cache queue, wherein the uniform cache queue includes multiple entries, each entry corresponding to a respective one of the plurality of cache queues; scheduling the stored messages in the uniform cache queue to a plurality of outputting scheduling queues according to their respective priorities; and transmitting the stored messages from the scheduling queues to respective terminals by using a transmit channel corresponding to the scheduling queues.

Abstract: An electronic cigarette includes a circuit unit, an oil container, an atomizing unit, and a sealing plug. The circuit unit is coupled to a lower portion of the atomizing unit. The oil container is mounted to the circuit unit and is detachable from the circuit unit. The atomizing unit is received in the oil container and is coupled to the circuit unit. The atomizing unit is detachable from the oil container and the circuit unit. The sealing plug is configured to secure and seal the oil container when the oil container is detached from the circuit unit. Any one of the atomizing unit and the oil container can be changed separately when it is damaged or worn-out, and use cost is also lowered.
