Abstract: A valve body including an outer wall, an inner wall, and a connecting wall is provided. The outer wall has a first upper surface, a first side surface, and a second side surface. At least one of the first side surface and the second side surface has a fluid hole. The inner wall is disposed within the outer wall. The inner wall shields the at least one fluid hole. A third side surface has an inner opening. The connecting wall is disposed within the outer wall. The connecting wall connects the inner opening of the inner wall and the fluid hole of the outer wall. Furthermore, an electromagnet switch valve and a bed structure are also provided.

Abstract: An air mattress control system is disclosed. The air mattress control system comprises a mattress and a gas regulating device. The mattress comprises a plurality of inflation layers. The gas regulating device comprises a first three-way solenoid valve, a pumping motor, a second three-way solenoid valve, a connecting conduit, a gas guiding device, and a control device. The pumping motor connects the first three-way solenoid valve and the second three-way solenoid valve connects the pumping motor. The connecting conduit connects the first three-way solenoid valve and the second three-way solenoid valve. The gas guiding device connects the connecting conduit and a plurality of the inflation layer. The control device controls the switch of the first three-way solenoid valve and the second three-way solenoid valve, and starting the pumping motor to inflate or deflate the plurality of inflation layers.

Abstract: A mattress structure including a base, an air bag structure and a fluid driving device is provided. The air bag structure is disposed on the base. The air bag structure includes a plurality of independent sub air bag structures. A plurality of supporting structures are disposed in each of the sub air bag structures. The fluid driving device is connected to the sub air bag structures so as so inject fluid to the sub air bag structures selectively. When the fluid driving device injects the fluid to at least one of the sub air bag structures so as to make the at least one of the sub air bag structures expand, each of the supporting structure is connected to two opposite surfaces of the expanded sub air bag structure.
