A pneumatic control valve device comprises an internal hollow valve body, an elastic assembly and an electric control module. The valve body is provided with an air inlet channel, an inflation channeland an air release channel which communicate with the outside, and a one-way valve is arranged in the air inlet channel. The air inlet channel is used for introducing air, and the inflation channel is used for supplying air to a pneumatic cavity. The elastic assembly is arranged at the end, communicating with the outside, of the air release channel. The electric control module comprises a circuitboard, an elastic first electrode and a memory alloy wire connected with the first electrode. One end of the first electrode is connected with the elastic assembly, and the other end of the first electrode is electrically connected with the circuit board. The end, far away from the first electrode, of the memory alloy wire is electrically connected with the circuit board. The electric control module is used for controlling the elastic assembly to close or open the air release channel.
