[0002] An inflatable boat is a kind of boat that is inflated, and is mostly made of rubber, so it is also called a rubber dinghy. It can be compressed when not inflated. It is driven by a motor or human power. In order to improve the safety of the inflatable boat during navigation, improve the reliability of the inflatable boat, and prevent the sudden damage of the air chamber and the leakage of all the gas, an elastic partition plate is usually used to divide the air chamber into several sealed compartments with similar volumes, and each compartment is provided with an inflation device. The existing multi-chamber inflatable boat is provided with an air nozzle or an inflation device on each air chamber, and the user needs to inflate and deflate each air chamber one by one, which is inconvenient to operate.

[0003] A multi-chamber inflatable boat communication device is disclosed in Chinese Patent Utility Model No. CN220884721U, which comprises a bottom plate, two press-type inflation nozzles are arranged on the bottom plate, a press switch is arranged at the upper end of the press-type inflation nozzle, the press switch is located at the top of the bottom plate, an elastic cover is arranged above the bottom plate, the elastic cover and the bottom plate are sealingly connected, and a cavity channel is arranged between the elastic cover and the bottom plate. The utility model communicates multiple air chambers, and the cavity channel is arranged outside the air chamber. At the same time, the press-type inflation nozzle is used instead of the valve body inside the air chamber and the knob outside the inflatable boat body. However, after the device is installed on the inflatable boat provided with multiple air chambers, all the press switches need to be opened one by one to perform the inflation and deflation operation, which is complicated to operate. Moreover, the elastic cover is exposed outside the inflatable boat body and is easy to be damaged. Frequent opening and closing of the elastic cover also leads to poor sealing between the elastic cover and the bottom plate, which is easy to cause air leakage and affects the inflation and deflation effect.
