The working process and principle of the utility model are as follows:

when the air pump starts to work, the motor rotates at a high speed to form an air pump vibration source. The vibration energy is weakened by the consumption of the vibration reduction and noise elimination chamber 214 in the first air pump mounting mechanism 21 around, and the vibration energy is continuously weakened by the consumption of the inner isolation cylinder assembly 223 after being transmitted to the second air pump mounting mechanism 22; still further lowered by the spring mount attachment 224.

When the air pump starts to work, the motor rotates at a high speed, and pneumatic components inside the air pump move at a high speed to form noise. The sound waves thereof are transmitted in the continuous compartment formed in the first air pump mounting mechanism 21 and the second air pump mounting mechanism 22 while being attenuated by the consumption of the vibration damping and silencing chamber 214, the inner isolation cylinder assembly 223. Because the joint surface of the first air pump mounting mechanism 21 and the joint surface of the second air pump mounting mechanism 22 are in the normal direction, the sound waves are folded in cavities and gaps with different sizes in different dimension directions, and the energy is continuously attenuated. After noise sound waves are transmitted into the air pump silencing mechanism 23 surrounding the outside of the first air pump installation mechanism 21 and the second air pump installation mechanism 22, the noise sound waves enter silencing folding cavities with different sizes and internal interval spaces which are continuously arranged in parallel around through the gaps 2344, enter the sealed first parallel surrounding silencing mechanism through holes on the upper bottom surface and the lower bottom surface, and further consume most noise sound waves with different frequencies in narrow spaces in different dimension directions, change, refract, reflect and superimpose acoustic properties such as phase wavelength, so that the multi-dimensional silencing subsystem has the function of eliminating noise with different frequencies for the operation of an air pump motor.

When the air pump starts to work, the motor rotates at a high speed, and pneumatic components inside the air pump move at a high speed to form noise. The sound wave can be transmitted and amplified through the air channel working devices such as an air pipe, an air cavity and the like. After the part of sound waves enter the air path conditioning silencer 236 through the air path, the cavity of the air path conditioning silencer adopts asymmetric, irregular curved surfaces and inclined surfaces in the dimensions of different directions up and down, front and back, left and right, and meanwhile, a spacing baffle is arranged in front of the air outlet hole, the sound waves are transmitted, refracted and reflected back and forth, consumed, and the acoustic properties such as phase wavelength are changed, overlapped and offset, and the first parallel folding silencing mechanism 234 and the first parallel surrounding silencing mechanism 235 which are enclosed outside also inhibit the amplification effect of the cavity resonance. Thereby conditioning uniform and low-noise air flow to be discharged through the air outlet.

The utility model adopts the design of continuously nesting and parallelly dissipating different dimensional spaces in a smaller space for vibration and noise generated by different reasons of the system, and plays roles of reducing the influence of vibration generated by the air pump on the control box body in the smaller control box body space, isolating different frequency noise generated by the air pump motor in operation, reducing the propagation and amplification of the noise through the air pipe cavity passage.

In conclusion, the utility model can greatly reduce vibration and transmission generated by the operation of the air pump in a small space, greatly reduce noise and transmission of the air pump, and has the characteristics of reasonable structure, simple assembly and low requirement on installation precision.

The air pump silencing mechanism 23 is provided with a positioning hole and is matched with the electromagnetic valve vibration reduction and sound insulation substructure 3 for positioning, the edge of the air pump silencing mechanism stretches out, the air pump silencing mechanism is lapped on the reinforcing ribs of the electromagnetic valve vibration reduction and sound insulation substructure 3, the multi-dimensional vibration reduction and sound insulation device system is fixed through upper and lower box body pressing, and vibration transmission is further reduced through flexible connection.

In a preferred embodiment, after the multi-dimensional vibration damping and sound insulation device system is installed and placed, the air pump installation module 6 and the electromagnetic valve group installation frame module upper portion 313 of the electromagnetic valve group installation frame module lower portion 312 in the electromagnetic valve group module 8 are in an inverted hanging state.

The working process and principle of the multidimensional vibration reduction and sound insulation device system are as follows:

when the air pump starts to work, the motor rotates at a high speed to form an air pump vibration source. The vibration energy is weakened by the consumption of the vibration reduction and noise elimination chamber 214 in the first air pump mounting mechanism 21 around, and the vibration energy is continuously weakened by the consumption of the inner isolation cylinder assembly 223 after being transmitted to the second air pump mounting mechanism 22; still further, the vibration energy transferred to the upper and lower cases 131, 132 is greatly reduced by the elastic attachment 224.

Vibration energy transmitted to the lower box body 132 of the upper box body 131 by the vibration source of the air pump is continuously attenuated and mixed due to partition and change after passing through the inclined plane structure 43 and the groove structure 44, and finally is separated by the elastic column connecting module 11 connected between the upper box body 131 and the lower box body 132, so that rigid vibration of the box body is avoided. The vibration reduction and sound insulation box body substructure 1 realizes the vibration reduction function thereof.

When the air pump starts to work, the motor rotates at a high speed, and pneumatic components inside the air pump move at a high speed to form noise. The sound waves thereof are transmitted in the continuous compartment formed in the first air pump mounting mechanism 21 and the second air pump mounting mechanism 22 while being attenuated by the consumption of the vibration damping and silencing chamber 214, the inner isolation cylinder assembly 223. Because the joint surface of the first air pump mounting mechanism 21 and the joint surface of the second air pump mounting mechanism 22 are in the normal direction, the sound waves are folded in cavities and gaps with different sizes in different dimension directions, and the energy is continuously attenuated. After noise sound waves are transmitted into the air pump silencing mechanisms 23 surrounding the first air pump installation mechanism 21 and the second air pump installation mechanism 22, the noise sound waves enter silencing folding cavities with different sizes and internal interval spaces which are continuously arranged in parallel around through gaps, enter the sealed parallel surrounding silencing modules through holes on the upper bottom surface and the lower bottom surface, and further consume most noise sound waves with different frequencies in narrow spaces with different dimension directions, change acoustic properties such as phase wavelength, refract, reflect and superimpose the noise sound waves, so that the multi-dimensional silencing subsystem can realize the function of eliminating noise with different frequencies for the operation of an air pump motor.

When the air pump starts to work, the motor rotates at a high speed, and pneumatic components inside the air pump move at a high speed to form noise. The sound wave can be transmitted and amplified through the air channel working devices such as an air pipe, an air cavity and the like. After the part of sound waves enter the air path conditioning silencer 236 through the air path, the cavity of the air path conditioning silencer adopts asymmetric, irregular curved surfaces and inclined surfaces in the dimensions of different directions up and down, front and back, left and right, and meanwhile, a spacing baffle is arranged in front of the air outlet hole, the sound waves are transmitted, refracted and reflected back and forth, consumed, and the acoustic properties such as phase wavelength are changed, overlapped and offset, and the first parallel folding silencing mechanism 234 and the first parallel surrounding silencing mechanism 235 which are enclosed outside also inhibit the amplification effect of the cavity resonance. Thereby conditioning uniform and low-noise air flow to be discharged through the air outlet.

When the electromagnetic valve group starts to work, the internal iron core reciprocates and collides with other parts, so that vibration and noise are generated. The vibration wave is greatly reduced due to the buffer design of the ribs and ribs of the contact parts with the lower part 312 of the electromagnetic valve set mounting frame body module and the upper part 313 of the electromagnetic valve set mounting frame body module, and is further reduced due to the design of the inverted suspension structure and the connection mode. Noise sound waves enter the silencing folding cavities which are arranged around and are parallel and have different sizes and internal interval distances through gaps, and enter the sealed parallel surrounding silencing module through holes on the upper bottom surface and the lower bottom surface, so that most noise sound waves with different frequencies are further consumed in narrow spaces in different dimension directions, acoustic properties such as phase wavelength and the like are changed, refracted, reflected and overlapped, and the noise elimination function is realized. Because the noise acoustic characteristics are high-frequency, fine-hole noise-reducing cotton is paved on the surfaces of the noise-reducing folding cavity, the parallel surrounding noise-reducing modules and the like, and the noise-reducing function is further optimized.

The multidimensional vibration reduction and sound insulation device system adopts the design that different dimensional spaces are continuously nested and parallelly dissipated in a smaller space in a targeted manner for vibration and noise generated by different reasons, and plays roles of reducing the influence of vibration generated by an air pump and an electromagnetic valve during operation on a control box body, isolating different frequency noise generated by an air pump motor during operation, reducing noise generated by impact generated by the electromagnetic valve during operation, and reducing the propagation and amplification of the noise through an air pipe cavity passage in a smaller control box body space.

In conclusion, the multidimensional vibration reduction and sound insulation device system can greatly reduce vibration and propagation generated by the control system in the intelligent surface support system due to the operation of the air pump and the electromagnetic valve group in a small space, greatly reduce noise and propagation generated by the control system in the intelligent surface support system due to the operation of the air pump and the electromagnetic valve group, and has reasonable structure, simple assembly and low requirement on installation precision.
