Referring to fig. 3 to 7, in fig. 3, the exhaust valve plate 1 is attached to the exhaust base 3 and blocks the exhaust port 31, when the compressor exhausts air, the exhaust pressure overcomes the elastic force of the exhaust valve plate 1, the exhaust pressure pushes the right end of the exhaust valve plate 1 away from the exhaust port 31, the right end of the exhaust valve plate 1 is attracted to the magnet 5 in the process of moving to the exhaust baffle 2 (see fig. 4), and then the spiral spring 4 is compressed until the exhaust valve plate 1 moves to be in contact with the exhaust baffle 2, and the spiral spring 4 and the magnet 5 are accommodated in the circular groove 21 (see fig. 5); the spiral spring 4 provides buffer for the movement of the exhaust valve plate 1 to the exhaust baffle 2, and the buffer effect of the spiral spring 4 is favorable for reducing the impact force of the exhaust valve plate 1 and the exhaust baffle 2 and reducing the collision noise of the exhaust valve plate 1 and the exhaust baffle 2. When the compressor finishes the exhaust, the exhaust valve plate 1 recovers and deforms towards the exhaust port 31 under the action of the self elastic force, the air release valve plate 1 is stretched and deformed by pulling the coil spring 4 through the magnet 5 (see fig. 6), when the elastic force of the deformation of the spiral spring 4 reaches the suction force of the exhaust valve plate 1 and the magnet 5, the magnet 5 is separated from the exhaust valve plate 1 (see fig. 7), part of the kinetic energy of the exhaust valve plate 1 is converted into the elastic potential energy of the spiral spring 4, finally, the exhaust valve plate 1 returns to be attached to the exhaust base body 3 (see fig. 1) under the action of the elastic force of the spiral spring 4, the elastic potential energy is dissipated by simple harmonic vibration after the spiral spring 4 rebounds, the kinetic energy of the exhaust valve plate 1 when colliding with the exhaust base body 3 is favorably reduced, the collision impact force of the exhaust valve plate 1 and the exhaust base body 3 is reduced, and the collision noise of the.

It should be noted that, if the exhaust valve plate 1 is not separated from the magnet 5 after being attracted, on one hand, the coil spring 4 loses the buffering effect on the exhaust valve plate 1, and on the other hand, the attaching force between the exhaust valve plate 1 and the exhaust base 3 is also reduced, which affects the normal function of the compressor, so that the exhaust valve plate 1 needs to be separated from the magnet 5 before (or while) returning to the position where the exhaust valve plate 1 collides with the exhaust base 3.
Alternatively, this can be achieved by adjusting the relationship between the stiffness of the coil spring 4 and the attractive force of the magnet 5, for example, by setting the product of the distance from the magnet 5 to the discharge valve plate 1 and the stiffness of the coil spring 4 to be larger than the attractive force when the magnet 5 and the discharge valve plate 1 are attracted, so that the discharge valve plate 1 can be separated from the magnet 5 before returning to the discharge base 3.

In addition, in this embodiment, the amplitude of the tension deformation of the coil spring 4 is larger, which is beneficial to converting more kinetic energy of the exhaust valve sheet 1 into elastic potential energy of the coil spring 4, further beneficial to reducing the kinetic energy of the exhaust valve sheet 1 when colliding with the exhaust base body 3, further beneficial to reducing the collision impact force of the exhaust valve sheet 1 and the exhaust base body 3, and reducing collision noise.
