Patent attributes
A pump-valve integrated mechanism includes an air pump driven by a power source. A main air channel provided inside the valve base is connected to the air pump and has a decompression structure. The main air channel is connected to an air inflation structure which includes a branch air channel and an air nozzle. A check valve is provided inside the branch air channel. The branch air channel between the check valve and the air nozzle is provided with an air deflation hole. An electromagnetic valve is provided between the air nozzle, the air deflation hole, and the check valve. During air inflation, the electromagnetic valve controls the check valve to become connected to the air nozzle, and the air deflation hole is closed. During air deflation, the electromagnetic valve controls the air nozzle to become connected to the air deflation hole and the check valve is closed.
