In the above, the respective devices function as:

the elastic plunger 3 balances the air flow through the elastic capacity of the structure, when the air pressure is too high, the elastic plunger 3 is compressed, so that the air pressure is reduced, and in addition, when the air pressure is too low, the elastic plunger 3 extends due to too low pressure, so that the air pressure is improved;

With regard to the above-described device, the specific operation thereof will be described in detail hereinafter.

In this embodiment, the elastic plunger 3 includes an airtight ring pipe 301, and the inner wall of the airtight ring pipe 301 is mirror-polished to form a smooth mirror surface, which has two functions: firstly, the air tightness is improved, and the gas is prevented from overflowing from the concave-convex surface to influence the internal air pressure; and secondly, the rear closing baffle 303 can slide better. While polishing processes are very common in the art and are not illustrated here. Damping springs 302 are fixedly mounted on the inner walls of the two ends of the air-tight ring pipe 301, a sealing baffle 303 which is in contact with the air-tight ring pipe 301 in a fitting manner is fixedly mounted at the tail end of each damping spring 302, clear oil is smeared at the contact part of each sealing baffle 303 and the air-tight ring pipe 301, and the smeared clear oil can close the gap between each sealing baffle 303 and the air-tight ring pipe 301 under the action of atmospheric pressure.

In the above, it is further described that the damping spring 302, in order to better describe the function of the above structure, the damping motion is first described, and the damping motion is first occurred in the vibration motion, specifically: in the vibration, because the friction force always exists, the energy obtained by the vibration system at first continuously applies negative work to the system due to the resistance in the vibration process, so that the energy of the system is continuously reduced, the strength of the vibration is gradually weakened, the amplitude is smaller and smaller, and finally the vibration is stopped. The damping method is divided into three modes according to the damping intensity:

firstly, when the damping is strong, the damping vibrator hardly vibrates, the amplitude is gradually reduced, and stable balance is achieved, which is called over-damping;

when the damping is weak, the damping vibrator must slowly reduce the amplitude gradually through multiple vibrations and finally return to a balance position, so that the time for achieving stable balance is longer, which is called under-damping;

another situation is that the damped vibrator reaches a stable equilibrium at the smoothest speed and the shortest time, called critical damping.

In the invention, the damping spring is arranged as the buffer structure, the function of the damping spring is to buffer the air pressure by utilizing the characteristic of damping, and the aim of the damping spring is to always ensure the stability of the air pressure and prevent the frequent change of the air pressure caused by the elastic potential energy of the buffer structure or other reasons.
