▎ 摘　　要

NOVELTY - The gateway has a water tank (16) whose side is installed with an electromagnetic pump (1) through a mounting seat. An end of the electromagnetic pump is welded with a supporting rod (2). A top portion of the supporting rod is provided with an atomizing nozzle (5) through a clamping sleeve. A top portion of the water tank is connected with a PVC sleeve shell (10). A side of the PVC sleeve shell is connected with a heat absorbing box (11) through a bolt. An inner side of the heat absorbing box is filled with graphene heat absorbing cotton (13). An inner side layer of the PVC sleeve shell is provided with a waterproof curing layer. A top portion of a gateway (17) is provided with a rubber pressurizing plate (6). A top portion of the rubber pressurizing plate is embedded with a bearing (9). USE - Internet of things (IoT) gateway e.g. inter-network connector and protocol converter and computer system, for performing wide area network interconnection and local area network interconnection. ADVANTAGE - The gateway is simple in operation and convenient for production, and satisfy utilization requirements. The gateway avoids moisture entering the PVC sleeve shell. The gateway is convenient for injecting clean water on the electromagnetic pump so as to pump the clean water to the atomizing nozzle in a convenient manner.
