The safety protection device contains a control unit, a transmission unit, and a throttle unit. The control method contains the following steps: step A: setting a condition parameter X of the control unit; step B: engaging the safety protection device into an operational mode; step C: determining if an external condition X0 satisfies the condition parameter X; if yes, continuing to the step D; otherwise, returning to the step B; and step D: turning off the throttle unit through the transmission unit driven by the control unit. A valve is configured inside the throttle unit and connected to a base through a driving device and to the transmission unit. The control unit contains an energy storage/release device configured on the throttle unit. A moveable block is configured inside the energy storage/release device. The transmission unit, together with the block, controls the open and close of the valve.
