The first gas transmission channel 140 of the one-way valve 001 is communicated with the main gas chamber of the air bed, and the second gas transmission channel 150 of the one-way valve 001 is simultaneously communicated with a plurality of auxiliary gas chambers through pipelines. Thus, when the inflation operation is performed, the inflator 002 is started, the sealing valve plate of the inflator 002 is opened to input the gas from the first gas transmission channel 140 to the diversion gas chamber, and then the gas is distributed from the diversion gas chamber to each auxiliary gas chamber through the pipeline; meanwhile, due to the fact that the sealing valve plate of the inflating pump is opened, the unidirectional sealing piece 200 is pushed open under the thrust action of the sealing valve plate, and gas enters the main air chamber of the inflating bed at the same time, so that the main air chamber and the auxiliary air chamber are inflated at the same time, and inflating efficiency is improved. After the inflation is finished, the air pressure in the main air chamber and the auxiliary air chamber is basically consistent, the air in the main air chamber cannot enter the auxiliary air chamber, a one-way sealing element 200 is arranged between the auxiliary air chamber and the main air chamber, and the air in the auxiliary air chamber cannot enter the main air chamber.

The one-way seal 200 is located on a side of the baffle 120 away from the first gas delivery passage 140, in other words, the first gas delivery passage 140 and the one-way seal 200 are respectively located on both sides of the baffle 120 in the axial extending direction of the cylinder 110. For convenience of description, the side of the baffle 120 close to the first gas transmission channel 140 is a first plate surface, and the side of the baffle 120 far from the first gas transmission channel 140 is a second plate surface. Under normal conditions, the one-way sealing element 200 can be always kept in a position of being attached to the second plate surface to block the side of the second air delivery channel 150 far away from the first port 111.
