The damper assembly 23 includes a damper block 231, a plurality of compression springs 234, and at least two elastic members 235; the damping block 231 is a damping block 231 with an accommodating cavity 232, and through holes 233 for the connection block 21 to penetrate through are formed at two ends of the damping block 231; the two elastic members 235 are respectively fixed at the inner sides of the two through holes 233, are positioned between the through holes 233 and the connecting block 21, and the connecting block 21 is in close contact with the through holes 233; a plurality of compression springs 234 are arranged in the accommodating cavity 232 of the damping block 231, and both ends of each compression spring 234 are respectively elastically connected with the damping block 231 and the connecting block 21; a plurality of first limiting holes 211 for connecting the compression springs 234 are formed in the outer side of the connecting block 21, and a plurality of second limiting holes 236 which correspond to the first limiting holes 211 and are used for connecting the compression springs 234 are formed in the inner side of the damping block 231; the plurality of compression springs 234 are evenly distributed in an annular array; when the pressing plate 221 moves downward, the fixing rod 223 can slide in the limiting groove 213, so that the moving direction and distance of the pressing plate 221 are limited, and the damping spring 224 cannot be used normally due to the inclination of the pressing plate 221.

The device also comprises a heat dissipation component 3, wherein the heat dissipation component 3 comprises an air inlet 31 arranged at one side of the box body 1, an air outlet 32 arranged at the other side of the box body and a blower 33 fixed at the inner side of the air inlet 31; wherein, the air inlet 31 and the air outlet 32 both penetrate through the box body 1 and are communicated with the inside of the box body; in this embodiment, when needing to dispel the heat to the electromechanical device inside box 1, start hair-dryer 33, make hair-dryer 33 blow gas to electromechanical device's inner structure, near hair-dryer 33 produced the negative pressure this moment, inhale box 1 with external gas through air intake 31 in, and blow to electromechanical device inner structure through hair-dryer 33, take away the heat that produces when electromechanical device's inner structure operates, then blow out hot gas through air outlet 32, make box 1 inside and external one form a circulation gas circuit, thereby can dispel the heat to electromechanical device constantly and cool down.

Specifically, when the electromechanical device is operated in the box 1, a large amount of sound and vibration can be generated, wherein most of the sound can be absorbed by the sound insulation layer 13, so that the sound is prevented from being transmitted to the outer side of the outer shell 11 to cause noise influence, and meanwhile, the force generated by part of the vibration can be absorbed, and the transmission of the vibration is reduced.

The sound insulation layer 13 can be made of sound insulation felt material, and the sound insulation felt has good sound insulation performance and damping vibration attenuation effect; in addition, the sound insulation layer 13 can also be made of sound absorption cotton material, and the sound absorption cotton also has good sound insulation performance and damping vibration reduction effect, but compared with the sound insulation felt, the sound absorption cotton has weaker damping vibration reduction effect than that of the sound insulation felt, and the sound absorption cotton has poor flame retardance, so that when the disaster occurs in the electromechanical equipment, the disaster is easily diffused, the economic damage is deepened, and therefore the sound insulation felt material is selected for making. It should be noted that other materials than those used above may be applied to this embodiment.

In the embodiment, when the electromechanical device operates in the box 1, the vibration generated by the operation is transmitted to the connecting block 21 through the box 1, and when the box 1 is vibrated by the transverse force, the transverse direction of the connecting block 21 is vibrated, so that the compression spring 234 in the connecting block 21 is elastically deformed to generate an elastic force, and the generated elastic force and the transverse force are offset with each other, thereby reducing the transverse vibration of the outer housing 11; when the outer shell 11 receives the vertical force and vibrates, the connecting block 21 extrudes the damping spring 224 through the pressing plate 221 of the damping structure 22, so that the damping spring 224 is extruded to generate elastic deformation to generate elastic force, and then the elastic force of the damping structure 22 is offset with the vertical force, so as to slow down the vibration of the vertical direction of the box body 1.
